III. Programme overview

For the owner's request, we design to ds7400xi bus system alarm host hardware platform security center software as software platform for large alarm system.

Ds7400xi is bus-multi zone alarm control hosts, all with functionality, scalability, quality and stability characteristics, are widely used in the community, buildings, factories, and other occasions in the large alarm system.

The main features of the host are:

1. stand with eight to two core bus (without power supply) Extensible 120 zone, a total of 128 zones.

(Note: the host 4.0 version number before total defense to 128, 4.0 after the start of the number of total protection zones, for currently listed 248 4.0 later versions, the programme achieve earlier, host version 3.0 + series)

2. bus length up to 1.6km (f φ1.0 m m 2).

You can take bus amplifier to extend the length of the bus. You can use a star, concatenated and mixed etc. to flexible cabling, in no more than the total number of stand, paragraphs bus bus expansion device is no limit to the number of requests.

3. Add 15 keyboard, divided into eight separate partitions, separate independent defense/disarmed.

4.90 group personal action password; 15 programmable zones functionality; 400 historical events for inspection.

5. you can select multiple zone expansion modules; there are 8 zone expansion modules ds7432, single-zone expansion modules ds7457, dual-zone expansion modules ds7460, with an output of single-zone expansion modules ds7465 and probe with code.

6. auxiliary output bus interface can connect ds7488 and dsr-32 relay output modules, and other peripherals.

For zone alarm and output one-to-one, many-to-one, one-to-many and many other alarm/output relationship.

7. adoption of the ds7412 modules can be converted to the RS232 interface for direct connection with the computer, or through a network interface device and lan connections.

8. accessible via pstn and alarm centre connection, support for 4 + 2, contactid, and other distribution formats.

9. for keyboard programming or remote control programming.

10. take the self-test function, online self detection system, part of the normal or not, and through the keyboard and display fault part of means of communication, facilitating maintenance and management.

In this system there are a total of 250 zone and 80 patrol point, through the Security Center software can be the trigger signal ds7400xi defense as a patrol of signal processing, so the system has a total of 330 zone number, total needs 3 ds7400xi host (v3.09 version).

The system in addition to patrol point, divided into eight partitions, each partition contains the unified management of floors, belongs to host liquid crystal keyboard arm/disarm and eliminating police, all of the information and alarm information is real-time in Security Center management software in the reaction, and automatically shows the warning area of the electronic map.

In terms of processing on the bus, because the building relative structure and clear, so the wiring is relatively easy, 3 1 root rvv mm2 4-core wire throughout the pipeline as well to the top three hosts of the bus, do not use more core of all the bus lines are placed in a multiple-core wire in order to prevent bus between potentially interfere with each other.

And bus extension equipment selection on use of 8 zone ds7432 expansion module, installed in the floor of the weak current wells, each floor of the detector and patrol buttons have the lines into the layer of weak current shaft connected to the power supply on and ds7432.

In guard tour system for processing, as will patrol system and alarm system integrated with the patrol system is on-line wired patrol system, will the zone access ds7400xi patrol switch as a 24-hour use of intangible zone, the Security Center software defined the zone to patrol zone and therefore can display real-time State Patrol.

The system can freely define patrol line, you can start multiple scheduled auto patrol line, you can manually start the patrol line and may prompt timely patrol, patrol is not timely, the patrol ahead, patrol errors trigger information. In the patrol button select, we chose a design more innovative patrol button, the button by Reed pipe and led, in accordance with normally open contact method to connect to the correct input on DS7432, when the band patrol officers will patrol with magnetic pen touch of the button, the Reed pipes will pick-up, light-emitting diodes and defense line conduction and shiny, tip patrol signal successfully trigger. Actual performance is quite good.

The design of the alarm linkage, we as a party provides two solutions, one soft linkage, we provide security center software interface through the appropriate API function to superior BA management system through a local area network transfer alert information.

Another is theHard linkage, through model 32 for DSR32 relay output module will alarm information through contacts connected to BA systems DI acquisition board, one DS7400XI host (4.0 version) you can connect four DSR32 relay output modules, the system realizes a one-to-one linkage, from superior BA system then on acquisition to the linkage of signal processing. Actual use since the hard easy linkage programme implementation, signal reaction speed is quite fast, so using this method.

The choice of the detector, taking into account the complex environment of relatively stable, attractive and relatively high requirements, so a large number of selection of the slimline ceiling DS936 passive infrared detector.

IV. conclusion:

The system uses a total of 3 single host, need DS7400XI PC provides three serial ports, therefore with a multi-channel serial port expander, system debugging has been damaged DS7412 serial communication module, the analysis of the phenomenon is due to the use of multi-channel serial port expander caused by quality problems, finally swapped the brand better serial port expander will solve the problem.

In the system of the actual use made of such problems, a patrol routes to patrol officers will also trigger the routes alarm zone positives, last in the software will patrol line along the zone select the patrol of a certain range of time can be automatically bypass, a good solution to the problem.

Taking into account the larger the system, if you use regular room centralized power supply can not meet the requirements, the systems of power supply are basically concentrated for electricity, nearby is the power supply on the detector relative concentration of supply.

The system to use hardware linkage, and the linkage of the hardware device can be used only by DSR32 DS7400XI host itself driven, and not by the Security Center software control, and set the inconvenience.

Current DSR32 relay modules and alarm management software is available through the serial port communication compatible use, much easier to system integration.

OPC technology in monitoring and control system (1)

1 creation of OPC technology

OPC (OLE for Process Control) technology is an object link and embedded technology in process control applications, contains a series of industrial automation interface specification.

This technique is to address the application software and a variety of device drivers for the communication of that hardware manufacturers and software developers separate, greatly improving the working efficiency.

With the continuous development of industrial production, due to the expansion of production scale and complexity of the process, industrial control software design face enormous challenges, namely to integrate an increasing number and variety of information.

In the traditional control systems, smart devices and smart device and system software information sharing is achieved through the drivers, the devices from different manufacturers use different drivers, forcing the industrial control software contains an increasing number of underlying communication module; in addition, because relative specific application drivers typically do not support hardware changes, allows industrial control software and hardware upgrades and maintenance is extremely inconvenient. There are at the same time, two customers not on the same device for data read and write because they have different, independent of the driver, at the same time on the same device, you may cause access violation, or even crash the system. OPC technology there is a great way to address these issues. OPC to OLE/COM/DCOM technology, uses the client/server mode for the industrial automation software object-oriented development with a unified standard, the standard defines application Microsoft operating system in the PC-based Automation client to Exchange data between real time. Using this standard, the hardware developer will replace the software developers for their own hardware product development integrated OPC interface program, and software developers may waive development driver work, put more effort into the development of its core product. This not only avoids the development of repetitive, but also improved the system of openness and interoperability.

2 application of OPC technology

OPC is connecting to a data source (OPC Server) and data users (OPC applications) software interface standard.

The data source can be a PLC, DCS, barcode reader and other control devices. With the control system, as the data source of the OPC server can be either and OPC applications running on the same computer, the local OPC Server or on a separate computer running remote OPC server. OPC interface can apply through the network to the lowest control equipment available to the original data as the data consumer (OPC applications) HMI (hardware monitoring interface)/SCADA (supervisory control and data acquisition), batch processing, and other automation programs and even more top historical databases, and other applications, can also be used for the application and a direct connection to a physical device. So the OPC interface is suitable for many systems have a high thickness softness of interface standards. OPC technology innovations are the users the ability to move any visualization or control system and choose any of the hardware (i.e. PC Board) through the OPC together, as shown in Figure 1.

As can be seen from the figure, the OPC standard software bus enables multiple onsite line systems can be integrated, such as PROFIBUS, CANopen network (open control local) network, Device Net (network), etc., can also be an in-depth reflection OPC and fieldbus standardization relations: OPC to provide field bus outside the important additional performance fieldbus field standardization's main goal is rapid, reliable data transfer.

While OPC enables standard communication can achieve such a degree that any OPC Server and application software to run networking will have no problems.

Multi-core processor application trend of high-performance video system design (1)

Clock frequency increases brought about by the high power consumption, deep sub-micron semiconductor manufacturing process leakage current of high power and more design challenges led processor design manufacturers begin thinking of turning to multi-core integrated solution.

Multi-core processor technology is improving processor performance of effective method, because the actual performance of the processor is a processor in each clock cycle to the total amount of the processing instruction, which increases a kernel, processors each clock cycle executable unit number will double. At the end of the dual-core processors started to enter the high-end server products. With Intel and AMD company has introduced a dual-core CPU, multi-core CPU in the application of the personal computer has become an irreversible trend, multi-core architecture in processor performance, low power consumption, reduced system circuit area, etc. have shown significant advantages.

In some ways, the embedded applications on processor needs tougher, especially for low-power, low cost.

To meet the current embedded device applications increasingly higher performance requirements, and as much as possible to reduce power consumption, in the field of high-end embedded processors a significant change is from the frequency increasing shift to multi-core architecture. Multi-core processor demand in many product areas increased significantly. To enhance the products a competitive advantage, embedded processor provider in multi-core competition began offering out there.

High-performance video system requires a multi-core processor

For embedded systems design engineers, the number of kernel is not a fashionable or product marketing gimmick, but when it is based on product performance requirements, power consumption, integration, cost, and other aspects of the trade-offs.

In particular, consumer electronics applications, single-core processor remains absolute. But some require more processing, control of applications, a dual-core processor already not in early spring, and such application duomeitilei products accounting for a large proportion, such as video surveillance (particularly with intelligent analysis function of monitoring equipment), video conference system, digital camera, automotive visualization system and so on.

For video surveillance applications, for example, with video monitoring application of the scale and networked, intelligent video surveillance system will be the development of an inevitable trend.

A new generation of intelligent analysis function monitoring system greatly extend video surveillance applications, in addition to the traditional security applications, human behavior recognition and intelligent traffic will open up a lot of emerging applications market.

Intelligent video analysis algorithm implementation forms most of the software, embedded software, the final product quality and performance of the performance of the hardware platform.

After all, the embedded platform resources are limited, relatively ordinary computer platforms, embedded platform computing capabilities relative to low for many, the core chip cache relatively small, the memory capacity of relatively small, and so on. These will give intelligent video analysis algorithms embedded implementation difficulty, intelligent video analysis algorithms for embedded implementations will be optimized. Hardware platform will lead to optimization strategies and extent different, if you choose, the higher the processor, in underlying operating instructions and on the open operation more optimization tools are complete, the system overall performance will be optimized for the better.

Intelligent video surveillance equipment most embedded devices.

Intelligent video surveillance belong to traditional video surveillance expansion and extension of, the traditional video monitoring on hardware platforms, intelligent video surveillance also must possess. But intelligent video surveillance and compared to traditional video surveillance, the user needs more diversified, for example: as a subway system users, their function is to detect whether the yellow line across the waiting crowd density is too large for suspicious objects, etc.; for a left bank system users, what they need is the ATM machine of intelligent monitoring analysis including whether to install fake keyboard, install the tunka, ATM machines, whether acts of violence, whether criminals face, etc. Therefore, on the one hand, the user needs of diversity can make the algorithm with the needs of users. On the other hand, smart video processing requirements chip with powerful processing capabilities, there are many algorithms must use parallel processing. Therefore, the traditional single-kernel microcontroller solutions facing great challenges, integration of MCU and DSP heterogeneous dual-processor or multiple-processor solution and a powerful computing capacity of multi-core processor is a smart video surveillance embedded platform alternative.

Dual-core processor — convergence-BF561

BF561 Blackfin ADSP processor is a product family in a member with high performance, it includes two independent ADI processor core, each processor core contains a double accumulator signal processor, a class of RISC instruction set, each kernel uses full SIMD architecture that contains video acceleration processing and image processing instructions.

Convergence-processor features reduce or avoid the use of separate digital signal and control processor requirements, reducing material costs while greatly simplifies hardware and software development tasks. Blackfin processor while providing comprehensive power management scheme, unique low-power and low voltage design (can be less than 2V Blackfin external voltage supply), reduces overall power consumption for 24 x 7 video surveillance is of great significance.

Dual-core BF561 has twice the processing performance BF533 processors, twice the on-chip memory, greatly enhancing data bandwidth and maintenance and code BF533 processors are fully compatible.

328KB BF561 processor with on-chip memory provides two parallel data-port, can be directly connected parallel AD and DA converters or other common peripherals. BF561 processor also built-in multiple independent DMA controller, supports data transfer automatically, so that processor core to minimize the burden. In addition, BF561 Blackfin processor continued with rich interfaces, to design a great convenience, for example, two dual-channel full duplex sync serial port, twoA support ITU-R 656 video data format of concurrent peripheral interface, SPI port.

Businesses must-have: 7 shopping centre electronic anti-theft alarm technology type description

The loss of the goods has undoubtedly increased the burden on enterprises, to this end, the burglar alarm industry applications.

Loss prevention gradually as the leader of domestic enterprises. Here to introduce 7 new shopping centre, electronic anti-theft alarm technology types.

(1) sound magnetic system

Tuning fork only in the oscillation frequency is the same as the circumstances causing resonance.

Acousto-magnetic system (Acusto Magnetic) is the application of this principle, achieving almost physics with zero false positives, fixed merchandise sound magnetic system labels into the system of detection area, produces resonance, but only in the receiver receives fourth consecutive by resonance signal (every 1/50 seconds), it emits a beep.

Acoustic characteristics of the magnetic system is an intrusion detection rate is high, nearly zero false positives, immunity, protect's exports width up to 3. 5 m, there are two kinds of hardware and software, on the Mall anti-theft tag most types of goods can be protected, and can repeat degaussing, even in the POS cash drawer side system is still functioning.

Sound magnetic system including the vertical system, channel type system and covert system of different kinds, more than 10 kinds of models to choose from, can be widely used in department stores, supermarkets, stores, video stores, grocery stores, drug stores, also available in the Office building and the environment.

(2) radio system

Radio systems (Radio Frequency, RF) using radio waves as the emission of the signal received, the detection in the frequency range of the electromagnetic wave 8.8MHz 7.4-, center frequency is caused by the label 8.2MHz in 8.5MHz interference, thereby triggering the alert.

The biggest advantage of radio system is a system cost is very low, easy to install. However, due to its anti-theft tag for the loop type, so the system vulnerable to interference of some items, such as cash drawer, and other electronic products, metal, etc., caused by a system of false positive or not.

Radio system with soft and hard two labels, you can protect most of the items in the shopping centre.

Two bearing distance between generally cannot be greater than 0. 9 m, usually used in only one import and export of shopping malls. Radio system with vertical and channel-both for the protection of the Department stores, clothing stores, supermarkets, etc.

(3) the electromagnetic systems

Electromagnetic wave systems (Electromagnetic System) using electromagnetic waves as the heartbeat.

Electromagnetic wave system label smallest, label the price is cheap, can duplicate the degauss, but vulnerable to magnetic or metallic substances in which produce false positives. Protection of width is generally 0. 9 meters. The system will not be on magnetic materials (such as audio and video tapes, magnetic card).

The new generation of channel-type electromagnetic systems is a software-controlled electronic anti-theft system, using a digital processing techniques and degaussing systems, cash register monitoring, closed circuit television monitoring system integration.

Use the quick degaussing plate, can duplicate the degauss, system cost. Electromagnetic systems have vertical and channel two. Application environment more in libraries, bookstores, music stores, hotels, supermarkets, etc.

(4) microwave systems

Microwave systems (Microwave System) using microwave as heartbeat, insensitive to ambient interference, its flexibility to covert installation (such as hidden under the carpet or hanging on the ceiling), suitable for shop decorative and attractive benefits.

But because of the large range of the receptacle shall, in a certain region cannot arrange merchandise, this gold to the inch, the businessmen will limit the use of space, therefore suitable for large department stores and store larger music shops, boutiques.

(5) frequency system

Frequency-division system (SplitFrequency) is made of high-tech low frequency radio frequency technology and signal security system.

When a detection zone anti-theft tag entry, label receives a launcher passes signal, and put it into half, and then has been divided into half of the information transmitted to the receiver, the receiver has received only half a signal when a beep, can effectively avoid interference from other radio waves. The system label light, small, cheap, stable performance, high rate of detection, anti-jammings well, does not cause false positives. Products are vertical and subtle type two, is a fashion shop more ideal anti-theft system.

(6) the intelligent system

Intelligent systems application unique technology, is an internally by IC control, battery-driven, set hard tags and alarm group as one of the system.

When the label was prized or with the goods being brought out shopping centre, the system will automatically alarm. The system can make the entire Mall-wide goods are protected, accurate report, tags can be reused, without damage of goods. Used to protect valuables, such as fashion, leather, fur coat, etc.

(7) the principle of system failure

Undermine the principle of the anti-theft system is a hard tags or magnetic locks.

Hard tag contains ink, when the thief trying to dismantle this hard tag, hard tags will emit ink, contaminated goods and thieves. Magnetic lock very easily dismantled, forcibly removed will destroy the goods, it is easy to use, has a very good deterrent effect, and the cost is very low, in clothing, glasses, jewelry, ties, silks and other goods, labels can be reused.

Intel R1000: RFID UHF storm eye?

【 RFID radio frequency Express 2007 April 13 rising 】 in March this year, is the most important news is that Intel developed UHF frequency bands highly integrated R1000 chip products.

With the debut of a high-profile R1000 product, wrapping his side's low-cost, multifunction and provincial energy consumption, aura has also sparked domestic and foreign trade experts and industry enterprises of the strong interest and buzz. RFID radio news reporter respectively within the industry, whether on Intel R1000 throws a drastic change in UHF market surveys and interviews.

Technology cost much advantage to create new business opportunities

It is understood that there are many technology Intel R1000 advantages, such as: single-chip products manufacturing cost less than $ 40, the volume of only 8x8mm, power consumption is only about 1.5W, feature highly integrated more comprehensive.

Intel has released a press release that the passive UHF RFID R1000 reader and 90 per cent of discrete components (RFID radio frequency express note: include receiving, transmission, baseband, modulation and demodulation functionality) integrated into a chip, design flexibility and further enhance the performance, lower energy consumption, even through the USB connection to your laptop 2.5W to obtain power; at the same time, support from a distance of handheld readers to distant access control readers, a wide range of applications.

In practice, UHF RFID reader has a broad development space, including supply chain management, asset tracking, access control systems, etc.

Although at present, RFID UHF technology is more mature, there are a number of standards, labels, price has decreased; however, the RFID UHF readers have become larger and more complex and more expensive trend, price from a few hundred dollars to $ 2000, consumes more energy, manufacturing components up to several hundred. And highly integrated R1000 seems to be able to resolve this issue, reduce the complexity of the chip design and production costs, enables manufacturers to produce smaller, cheaper and more innovative reader, thereby opening up new application areas of RFID.

User technical threshold lowered to promote reading and writing equipment manufacturers developing

Intel R1000 and several development tools package for sales to improve reader OEM supply of products to market faster, while also enabling end users of reader use, supply, remote management easier.

These have included Firmware. The tool supports the EPCglobal Gen 2 and ISO 18000-6C standard all models and data rate, including built-in support for dense reader mode DRM and carrier sense LBT, compliance with United States Communications Commission (FCC) and the European Telecommunications Standards Institute (ETSI).

In the development of the Intel Intel R1000 and end users, and enterprise software companies cooperate closely in the development of a set of software that can be used for device detection, management and supply, making enterprises from readers to data center can be better integration and data management.

Through cooperation, Intel, on the basis of the R1000, launched a based software solutions and software design kits (SDK), which with the leading software provider of high level application software as well as new standards compatible. At the same time, the SDK will also allow users to use common programming techniques to program on the reader, rather than having to hard to understand and use the microcontroller code.

At present, ultra-high frequency field technical difficulty high, industry experts believe that if you scale to achieve highly integrated reader chip manufacturing, you can significantly reduce technical barriers, and promote the emergence of the manufacturer of the reader; such as increasing ISO 18000-6B standards support, R1000 will further promote the UHF read/write device to miniaturization (RFID radio frequency express note: handheld, portable) direction.

UHF industry chain in rhythm with the competition and cooperation

As R1000 chips, Alien, Thing Magic and Samsung Techwin, 12 RFID reader manufacturers are also planned for the next few months, the manufacture and sale of used R1000 chip UHF RFID reader product.

If ThingMagic plans to complete the beginning of may – the reader module will use the R1000 Mercury5e and designed to be embedded handheld (PDA) or print — in the form of the encoder with Mercury4e, Mercury5e volume significantly reduced energy consumption is further reduced. There is also the Deister Germany developed two RFID reader module UDK2 and UDK20. In addition, some manufacturers also plans to use the R1000 production of micro-module, using this module, laptops or personal digital assistant to a RFID reader.

At the same time, competitive product R1000 have bright, including representatives from the United States Starport system and WJ communications company research and development of integrated chips also came to UHF "racetrack".

Of these, the company launched the Starport system SP7001 chip for UHF Gen 2 readers, advantage is small size, you can embed phone application for consumers; the disadvantage is that does not support dense reader module and cannot be used in supply chain management.

Research experts and industry enterprises the benevolent see benevolence and Moses

3G clairvoyance: video monitor thousands of miles away you

With China Telecom, China Mobile 3 g network, the public official yongcheng into the 3 g times.

Citizens feel the 3 g mobile phone bring convenience, making such a doubt, the 3 g mobile phone, high-speed mobile Internet features, also give rise to many new products? also extent changes life?

Terrible than the furtive pinhole?

Recently, the journalist received net of stringing, that someone is selling a more terrible than the furtive pinhole of monitoring devices, use the camera, you can use the 3 g mobile phone anytime, anywhere viewing dynamic of the monitored object.

It can and 3 g mobile phone network, via cell phone or computer, to a certain place at any time monitor. Users that have this stuff, after all what privacy? if you will use this technology to the illegal activities that will give the State and private property losses? in order to find out the truth, the reporter on this matter were investigated.

10: 00 am yesterday, reporters follow users provide contact information, dial a phone number, the phone is a surname WONG, Deputy Chief of the said user's candid camera device is a misunderstanding.

Their distribution is based on a 3 g technology network monitoring appliance. Can be abbreviated as 3 g camera. According to Wong Deputy General introduction, the so called 3 g camera, is the latest remote monitoring device. They not only all the procedures, and is the latest high-tech applications. This product is suitable for shops, homes, schools, offices and other places. And police, located on the video, this new monitoring device completely realized and 3 g networking, in addition to being able to see on the computer, you can see with the 3 g mobile phone.

To see a woman face freckles

In the company, the Deputy Chief told reporters demonstrates the functionality of the "telescope", he used the 3 g mobile phone to enter a Web address, immediately showed a place there is space, there seems to be a very big flat gate, Wong said this is the door to a foreign company.

The effect of out of control, the image is very clear, you can see what people are wearing clothes, or even a woman head wearing what head flower can distinguish out, than the traditional monitoring devices do not know how many times the clear. Even more surprising is that this preparation can go a week since the video information, including photos, automatically send SMS alarm. Journalists through the computer into a company of Jinhua monitoring system, the camera is looking in the company of the elevator, walking to work on time, to see clearly. Press the frame once amplification, the image still even see a woman face of freckles.

High technology is changing lifestyle

The company's yellow collectively, such monitoring device, it is precisely in order to protect the security of the CAAC, users do not understand the situation some concern is understandable.

In addition, the product is not a spy supplies, hope and "peeping". If it was used for illegal purposes, that's not the product itself. As someone said "more terrible than the furtive pinhole", it is better understood as a means to improve the monitoring, let criminals feel worse. As with the development of technology, some lifestyle will change.

On the new challenges of the traditional privacy

Journalists in the interview, the biggest feature of 3 g data flow velocity is greatly improved, the actual realization of the concept of the mobile Internet, let everyone out on the wired Internet relies heavily on the next one to two years, more people will choose to surf through the phone.

When people enjoy this great communication advances, also aware of the mobile Internet to life changes.

A surname Luo people interviewed by a reporter said, if their boss in his work on the "telescope", you can monitor them anytime, anywhere, he will feel to work as prick in the back, that's what privacy.

But the view was also expressed that this technique as long as the application to the case, it is a good thing. Interview a surname Lu's parents told reporters that if schools charge a device, he can watch son via mobile phones in the classroom is not mischief.

Existing public security video surveillance system exists three major defects

1 November, at its twelfth session, held in fair, gonganbudisanyanjiusuo Merlin, turning to face the public security information for monitoring video technology, said that, at present, with the monitoring network-scale is continually expanding and surveillance video applications, the existing public security video surveillance system is already insufficient to meet the needs of the police, a line-policemen for video surveillance network performance and the technical means to put forward higher requirements, mainly in three respects:

First, the monitoring network of image quality and a gap between the demands of case handling.

This issue arose in addition to the part of the quality of the camera Terminal capture needs to increase, one important reason is that in order to save storage space and transport costs, the video images are often large compression, decoding, details missing, many on the detection of useful information with data compression and loss.

Secondly, monitor network application without a smart technology.

Video surveillance network video content analysis also rely on artificial access real-time viewing, manually. With the expansion of the scale of monitoring networks, a massive growth of video data, image monitoring and access to a large amount of manpower, become restricted full video surveillance network performance bottlenecks. From mass-surveillance video get useful information or intelligence has become increasingly difficult. From a practical point of view of the application, the information should be retrieved and the query and the current application of the surveillance video is mostly just a reproduction of the scene to monitor and playback, it is difficult to meet modern security information application needs.

Third, video data mainly in monitoring designed online transfer, you cannot truly and police network data sharing between.

Monitoring of the equipment in the network number of the camera is very large, and whether real-time viewing or subsequent video file browsing, users can only access a small part of video resources, and limited to network bandwidth, the shared application could not be large. Similarly, other sectors of society's video surveillance data can not be achieved on the public network users access and sharing. This has caused a large amount of video data is a one of the islands of information, not fast and effective reach the hands of the police investigation.

Merlin Dr said, in response to the above questions, submit a surveillance video gonganbudisanyanjiusuo structured description of technical solutions.

Video is a structured description of how to video (unstructured data) to retrieve employee successive application of technology in depth. Surveillance video structured description of key technologies include surveillance video keyframe extraction and video summary, image feature extraction techniques, intelligent video analysis technology, chip technology and embedded devices, monitors, video structured description of the standard system, and so on five key technology.

Intelligent security monitoring and rapid reaction systems design and implementation (1)

Abstract: design of a rapid reaction embedded intelligent security monitoring system, moving target tracking, locating, fast capture facial images.

Using pattern recognition and image processing technology for facial feature extraction for analysis, and its characteristic quantities and face library feature to match the amount, whether or not to be illegal, and if you start alarm program.

With the improvement of living standards and the strengthening of security awareness, video monitoring system has been widely applied.

Current monitoring and control more to PC-based, you can only play a simple video recording function, also require special monitoring screen. For those few people access important places, through manual mode on the screen monitor is a chore, but PC also equipped with high-capacity hard drive to hold all of the video image, hard drive usage. To address this situation, this article has designed a unattended monitoring system. System in the range into the monitor does not save video image, when someone enters a monitoring areas will start the video recording of the program, while automatically fast capture face, using pattern recognition and image processing technology for facial feature extraction for analysis, and its characteristic quantities and face library features to match, determine whether the illegal workers, if the conduct of the police, and through remote monitoring center network reminder note. For seldom someone appears, use the monitoring system can reduce data capacity, reduce monitoring staff and do not worry about missing monitor object. This system is the original generation of products based on the hardware circuit design and software algorithms that have been improved. Proven system of reaction speed, speed, etc., are all recognition processing has been improved.

1 system overview

Camera control in the master system to work, in the absence of moving objects into the camera's data is not stored.

When someone enters into shooting the master system immediately control camera on illegal entry into the specified region of the human body for track and trace the process on face detection and quickly and accurately obtain the facial image, start the video recording feature at the same time; and then through a series of digital image processing methods on the facial image analysis and processing, to determine whether an attempted break-in, if you start the alarm system. Take advantage of more of these subsystems can form a monitoring network, various subsystems over a network connection with the monitoring center. Each subsystem has intelligent monitoring capabilities, so monitoring center only equipped with a duty officer to monitor more than 20 monitoring points, greatly reducing the use of the personnel.

2 system hardware

Because the system handle the data volumes larger and require real-time; it uses a combination of DSP and FPGA, coupled with the image data acquisition chip and memory chips that constitute the core image processing unit.

At the same time equipped with local alarm module, network transmission, etc, so as to constitute a complete surveillance system. System block diagram shown in Figure 1. Compared with the original system, this system made the following improvements: the original just as data buffered on-chip FPGA design for a master, control data input conditioning and output alarm, and the DSP, specifically used for image processing and transport. This can improve data processing speeds, thereby improving the responsiveness of the system.

2.1 system selection of major chip

(1) image acquisition chip adopts TVP5150.

TVP5150 with ultra-low power consumption, support NTSC/PAL/SECAM, format, high-performance video decoder. In normal working hours, it is only 115 mW of power consumption, by setting the internal registers, you can convert analog video signal YUV4: 2: 2 format ITU-R BT.656 digital signal, and direct to DM642 for processing.

(2) to provide a system of rapid reaction capabilities, image processing chip selection are particularly critical, complex factors, TI DSP selection of company-specific multimedia chip TMS320DM642 (hereinafter referred to as "DM642").

DM642 C64x kernel based, 720 MHz clock frequency, each instruction cycle can parallel 8 32 bit instructions that can reach 5 760 MIPS peak computation [6]. DM642 using level 2 cache structure (L1 and L2), which greatly improves the speed of the program. On-chip 64 bit the EMIF (External Memory Interface) interface to SDRAM and Flash memory, and so on for seamless connection, greatly facilitates the removal of large amounts of data. In addition, DM642 also owns three dedicated video port (VP0 ~ VP2) for receiving, processing, video and audio data, system extension is very convenient. In addition, DM642 the EMAC estuary and port extension from EMTF out ATA port, also when processing is complete of massive data provides storage channel [5]. DM642 need plus SDRAM (4-M64 bit) used to hold the procedure and cache digital video, and FLASH (4 M8 bit) for curing procedures for ROM boot.

(3) FPGA logic is responsible for implementing the system, output control, and internal cache timing control.

To achieve image real-time acquisition and processing, you need video acquisition and image processing work in parallel. Acquisition to the image data sent to the cache before the DSP interface design is crucial to the design of a direct impact on the responsiveness of the system. To increase the read speed of data cache, you can use FPGA internal resources to build high-speed dual-port RAM as the inner cache, the data frame processing alternate for data acquisition and processing at the same time, its internal structure shown in Figure 2, shown within the dotted line box. Acquisition of digital video signals through filtering, then fed into A logical unit, A responsible for generating clock and data logic control. Input video data in A control signal, into the buffer register b and c, and D in control unitControl, to a dual-port RAM. In order to achieve the real-time image acquisition and processing, makes FPGA for image data buffering and DSP read the image data will sync to RAM into equal 2 blocks, i.e. RAM1 and RAM2. In the system work, a piece for buffered image data, FPGA classification after signal buffer to write to the store; another piece of the DSP is used to read the image data, the DSP can be directly on the store of data operations. The cache structure of another feature is the FPGA and DSP on dual-port RAM addressing is switching back and forth. Because the DSP read RAM speed greater than the speed of the FPGA to write RAM, so the switching signal is issued only by the FPGA. When the FPGA classification buffered data is full RAM1, DSP FPGA to sending a break signal, at which point DSP read data in RAM1, FPGA RAM2 buffered data to be written. When data is full in RAM2, FPGA and DSP interrupt signal DSP read data in RAM2, RAM1 FPGA buffered data. So alternating image data read and write at the same time, which improves the speed of data processing.

Speed dome technology panorama of intelligent network night vision is direction (1)

Speed dome is a related optical, mechanical, electronic, and other areas of high technology products, its high-speed scanning preset, large ratio of low-speed capture, preset, and privacy zone mask, direct control properties, click tracking, alarm linkage, Chinese characters, overlay, wide dynamic capabilities of both good and bad to decide the quality of a high speed dome, while supporting all performance basis mainly with zoom lens with integrated camera, electronic slip ring and high-performance stepper motor performance.

Speed dome of birth history is not long, but it looks delicate, control of flexible, intelligent and so won users, many ball machine manufacturers also increase the intensity of research and development of high-speed ball, now manufacturers have made high speed dome basic control functions are relatively mature.

The function of diversity, networking and intelligence can be said that the current Quick ball the major trends in product development.

Speed dome as a monitoring system of the front-end device Imaging is clear, focused accuracy quickly is the key indicator, which in turn depends on the product selected a key components — integrated camera.

Integrated camera performance mainly in the image is clear, the focus is accurate, and zoom, color, and resolution.

Speed dome of horizontal and vertical directions of movement by two stepping motors, Center matrix to speed dome of movement commands are microprocessor-driven motor, motor or bad decision speed dome all motion parameters, like the preset point of high-speed scanning, large ratio of low-speed capture, cruise queue, figure scan, automatic tracking and enlarge accuracy can not be separated on motor processing and precise control.

At the minimum speed control when the image of jitter level to reflect the performance of high-speed ball in the mouth; preset point of accuracy depends on the degree of precision mechanical structure and stepping motor performance and control level, it can be said for motor control level can truly reflect the enterprise manufacturing speed dome level.

Quick ball camera function diversity refers to the product features will be strengthened, and can be applied to different environments, and more comprehensive, better compatibility.

Zoom and auto-tracking function is the latest high speed dome, two major technological breakthrough. Zoom is the monitoring process, the discovery monitor target, using the mouse to click the object, the high-speed ball the image transferred to the screen Center and click on the object's size smart zoom. Auto-tracking functionality is based on image processing techniques for extracting images in motion vector, speed dome under image moving object in the direction of movement.

Lightning protection technology has always been a subject of study of high speed ball, used only for the control signal to lightning protection, speed dome on video of lightning protection is also achieved a major breakthrough.

Network high speed dome will be the speed dome developed another direction, use now convenient network technology transfer video and control signals will greatly extend high-speed ball in monitoring industry applications, network capabilities as well as the products brought in some new applications, such as the current video monitoring is increasingly used in power and transport sectors, etc.

Intelligent speed dome in the main body and other equipment comprising intelligent recognition (face recognition and alarm, anomaly alarm, license plate recognition, etc.), automatic tracking (tracking moving objects), alarm linkage, automatic alarm and video, and other functions that the application of the "monitor" is more familiar, more intelligent and user-friendly.

Integrated high speed smart balls are equipped with large x optical zoom lens, the higher horizontal resolution, built-in high speed dome, you can quickly and accurately achieve positioning monitor; zoom features to more efficient surveillance camera focus objects images, suitable for monitoring public places and roads; in addition the General high speed intelligent ball with preset, pattern scan, automatic cruise, you can better achieve the city monitoring and many other special requirements.

Integrated high speed dome and PTZ cameras in General with more intensity than hidden, and thus very suitable for road traffic monitoring, in the present system of urban surveillance applications, integrated high speed smart ball has frequently to debut in a variety of applications.

Speed dome automatically tracking technology

Automatic tracking technology is based on intelligent recognition, image difference calculation, automatic identification of Visual range target movement direction, and automatically control the head on the goal of moving objects are tracked in the scope of the intelligent high speed dome camera to the left of this period, through the automatic configuration of high-definition zoom lens so that all actions are explicitly passed to the control center.

Once a zone when alarming, other related intelligence high speed dome will automatically rotate to alarm point began tracking, ensuring the monitoring image to record the movement of the target object.

In view of the above questions, the second generation of automatic tracking technology uses a lock tracking, that is, the operator specifies goals, intelligent speed dome will automatically track the trajectories of moving objects, for a specific person or object, you can lock tracking camera, even if other people or moving objects into the camera monitoring range, the camera will not be locked before with lost of target objects.

In a large square of the flow, as long as the manual lockout tracked target, it will not appear because of external reasons of tracking is not accurate.

At the same time, suddenly disappear for monitoring objectives of the special circumstances of a certain product set the disappearing after the associated object three options, the first was the place continued to keep track of disappearance; the second is that you can zoom in to the best tracking rate is continuously tracked targets mobile objects; the third is interrupted after automatic tracing, you can zoom in to the starting point of tracking rate.

Additionally, as the intelligence high speed dome gradually deepening of application, the user for movement and hardware selection is more extensive.

Some intelligence high speed dome is via built-in a paragraph integration movement to implement auto-tracking function, which makes the class high speed dome camera compatibility, if the use of other brands of movement would not be able to implement automated tracking capabilities. For compatibility, intelligent speed dome has a modular design, intelligent speed dome hardware can realize automatic tracking, this indoor IP high speed dome are compatible with more movement, use a wider range.

Speed dome products technology development status and trends

Network high speed dome

Network high speed dome is the development of high-speed ball features, is an important branch of traditional analog intelligence high speed dome camera with the perfect combination of Internet technology.

Quick ball tracking technology to security monitoring and bring new perspective

Quick ball has developed the technology, functionality is already very mature, however, is also faced with serious product homogeneity.

Quick ball prospects plaguing the ball machine development and production firms, many manufacturers in intelligent trend driven by automatically tracking technology as their own creative play. However, subject to technical and cost constraints, intelligent features also cannot get a wide range of applications, then the intelligent road to development will be a general interest in the industry.

Quick ball intelligent functionality

As the most representative of front-end monitoring equipment, fast ball, long-distance control, zoom, high definition images, presets cruise, automatic tracking, and other functions in green cities, transport, stadiums, port and other projects/industry increasingly play an important role.

But as the terrorist activity, plus the entire monitor profession toward the digitization, network development process, fast balls of intelligent features are more on the agenda. But in this trend, the auto-tracking has become a fast ball in recent years the rapid development of intelligent technology.

Front-end intelligent functionality

Current Quick ball already have some preliminary intelligence features, such as detecting machine internal temperature and humidity, automatically launch internal heating and cooling equipment, intelligent monitoring fans State, intelligent recognition system features such as a series-Kuk, however these intelligent functionality is specific to the ball machine internal working environment and ball machine performance Intelligent detection, not object to the outside world was monitoring Intelligent detection and analysis, and to monitor the front-end machine on target for Intelligent detection, you will need to combine IVS, intelligent modules (software) to complete.

Although it has not formed of intelligent application needs generally, but it can be expected, it will be a lot of applications to play traditional product incomparable role, but also in the future it will become fast ball technology one of the major trends. Quick ball of intelligent features are divided into the front-end machine independently and from back-end software platform with a common front camera operation to complete. Back-end intelligent software algorithms by the background analysis of video and then quick ball issue-driven commands. At the front end finish fast ball intelligent functionality, there are two ways to implement the algorithm of the smart module embedded into the DSP chip dome camera, the other is increased and intelligent module, the module's intelligent function of control input to the ball machine.

Automatic tracking technology

Auto-tracking is based on intelligent recognition, image difference calculation, automatic identification of Visual range target movement direction, and to automatically control the PTZ tracking of moving targets, at the same time meet the high definition of auto-zoom lens, when the target into the dome view until you leave the time, all video is clearly transmitted to the control center.

Once the system is an area when alarming, related quick ball will automatically rotate to alarm point began tracking, and can be set to start video or capture and start around lights, alarm and other linkage function.

On the ball, the mobile tracking feature can not require a back-end software platform to control, as long as the front-end to automate tracking of tasks.

When the target object into the ball machine vision range, the machine can automatically identify the target movement direction, and automatic control on cloud platform rotation and track on a moving target, so that the object is located in the central than-surface, while automatically to zoom on target. Automatic tracking continued into target left visible range of ball, the ball back to the original observation point for the next track.

Fast tracking the ball is on the ball machine mechanical tests for object tracking depends on its speed and accuracy, and in the action they are taking the center position, local amplification characteristics to meet the monitoring image clarity.

Automatic tracking of classification

Current Quick ball automatically tracks mainly in the area of automatic tracking and lock the precise tracking.

Regional track mainly refers to the machine if you have set up regional, track its trajectory, tracking is out of range, the machine automatically return to the VIP-points to a new round of tracking. Regional tracing functionality is suitable for monitoring objects or moving objects less environment, if you have a mobile person or object into the scope of the monitoring camera, the camera will be automatically tracked, but you cannot lock a particular character or target. Once in the monitoring area have multiple objects at the same time, the camera will follow the target object.

Lock tracking, that is, the user specifies the target, the opportunity to automatically track the ball object trajectory.

Lock tracking technology is implemented via a template matching algorithm, in Plaza such large-scale and people flow region can have very good monitoring results, as long as the manual lockout tracked targets, even if there are other moving objects in the monitoring area have not lost VIP-to lock target.

Lock tracking can be set to manual and automatic locking.

To manually lock tracking via mouse on the screen than to keep track of goals-a box, lock tracking the target. Regardless of the target movement or still are on other mobile objects for automatic tracking, tracking fast and smooth. Even in more than one appears on the screen, move the object ball is not on track. This feature applies to the complex environment of security monitoring. For example, catch the thief. If the monitor than-surface found a thief stealing, as long as the thief image than a box for-manually lock the ball machine will only track thief, without going to the track being the victim of theft, where, in a timely manner that thief caught for smoothly towards the opportune time.

The mobile automatic lock tracking is the first automatic tracking of moving objects, that is, the first movement with who.

If the first mobile destination stop and a second target move, it will automatically track the second mobile goals, tracking quickly and smoothly. This feature applies to unattended occasions, such as Treasury, arsenal, power stations and other important places.

Quick ball intelligent development prospects

At present, the faster the ball of the intelligent identification and tracking, and other technology is still in the emerging phase, the feature is not yet fully mature, complex situations or target move too

Fast, easy to lose. But there is no denying that these advanced technologies have given security monitoring industry innovation vision, with increased reliability, and the more the development of new technologies, such as: target of stateful, traffic statistics, face recognition, intelligent video surveillance system would be more widely applied.
