Security technology in the Beijing Olympics security application

The idea put forward by the Beijing Olympic Games is the "Green Olympics, high-tech Olympics and people's Olympics", we should base ourselves on a fast development of security technology to ensure the security and the Olympic Games, the security market will bring strong State of the Olympic Games.

In order to build a harmonious society, building green city, security system, particularly for video surveillance network needs will become more and more exuberant. This article discusses the security system of the latest technological advances, the Beijing 2008 Olympic Games security mechanisms.

The 29th Olympic Games to be held in Beijing in 2008, the most attention of the world's first Olympic Games in Beijing to provide the level of security.

As China's socio-economic development, China's construction project and the annual large-scale activities more and more, and the rest of the world, China is facing social and economic development because the contradictions arising from social security issues are also faced with the threat of terrorism and criminal brings hazards. Terrorism and the protection of urban safety has become a focus, enhanced security and counter-terrorism demand growth is very strong. It is estimated that between now and 2008, the Beijing Olympics will be the cause for the public safety building 500 billion yuan market. Security and protection of the latest technological advances in the security field of technology was also in the process of rapid development, so far, the major breakthrough has been achieved are: 1. standard-definition (SDStandardDefinition) class analog color CCD camera, not only the image sharpness has reached 540 lines (color), 570 lines (b/w), has all DI high resolution (72 × 576) of TV monitoring system. In addition, also launched a million pixels (1280 x 1024 or higher) level of a webcam, a high-definition (HDHlgh Definiton) series of next-generation camera.

2. in the image compression introduced H264 (or MPEG4 part 10 is), and will gradually replace MPEG4 and covers over the leading position of image compression. Because it can make use of bandwidth and storage capacity needed than dropped MPEG4 50 percent, the realization of the GIF format video in real-time on ordinary ADSL transmission, while row because H.264 encoding algorithm has a network layer and network layer structure, so for normal broadband with and wireless network adaptability to strengthen, not because of a network of influence the quality of transmission error. But H264 is still a hybrid (macroblocks) coding framework standard, the encoder is other encoder complexity of 3 times, the decoder is other decoder complexity of 2 times. In addition, in the space compression and time compression on strong scalability of small compressed (Wavelet) has also been applied. 3. launch the SoC (System on ChiP) single-chip system, allows the system to increase the complexity of the case, the device volume but can greatly narrowed. For example, the PhilipS company launched the μ m used 65 low-power CMOS technology with intelligent energy management technology ARM processor; Axis ETRAX companies (run simple Linux system CPU) and image compression chip ARTPEC-2. Especially the PhiliPs company recently introduced V I p e r Π Multimedia SoC platform, integrated with two tm3260 kernel for h.264 encoding operation provides powerful processing capability, integrated MIPS kernel PR4450 as operating system processor and inherited 7Nexperla powerful coprocessor, resolution up to 1920 × 1080 × 60i, there is a great improvement, will become the main force of security monitoring. 4.DSP chip features are more powerful, such as the PhiliPs company PNX-1500, 1700, TI DM642 company (720MHz) and Equator BSP-15 companies, such as new digital network security equipment, laying the Foundation for research and development. Upcoming also Leonardo da Vinci (Davinci) system, i.e. DM642 +. 5. except for CCD, CMOS and other imaging devices, it also launched a new concept of image sensing and processing system DPS (Digital PxelSystem), DPS is a pure digital image pickup system, it packs in-image sensor and image processor. DPS's core technology is a pick of pixels contains an ADC (analog to digital converters, digital analogto), capture the light signal, set fire to it directly and converted to digital signals, and therefore minimize the analog signal transmission noise generated by the operation. The advantages of the DPS will make the camera have a wider dynamic range to easily capture destination, can watch great site, and you can get a clear image detail, conducive to small things like monitor, its intelligent optical processing system will far superior to traditional CCD.

6 £ ® DVR DVR technology has greatly improved, has developed 24-32-channel full real-time embedded DVR and a high level of image acquisition and compression Board card, an international leading level. Network video recorder NVR and double-compression technology (MPEG4, JPEG) in dual stream DVR is beginning to appear. Network video recorder is likely to support the NVR LAN.WAN, PSTN.ISDN, XDSL, networks, and intelligent analysis functionality more closely.

7. using 100Hz deinterlace monitor, as a result of the high frame and progressive technology, you can make the image screen flicker-free and more stable so that Visual effects have been improved and protected by all ages. Next, display device from traditional 480 interlaced (intgrlacedscanning) transition to 1080i or 720 p progressive scan (ProgressivescaNning), and 1080p Full HD appears (full HD) display format. 8. has the video image of intelligent analysis called smart video, images of intelligent search and tracking will be the focus of the camera target tracking is becoming the focus of the application; "video content analysis software" demand it through automatic identification and retrieval of information contained in the image, while in traffic statistics (conning people) and automatic behavior recognition (behavior recognition) are applied. Latest video recording solution based entirely on the server, and uses the PCI $ hardware or software with encoding function, the system not only with multiple PCI 10 PCs, are more likely to be up to date on your knife back-Server (Blade-sever), to capture the public's image within the storage subsystem. At the same time, to achieve a more intelligent, distribution, requires intelligent video technology advanced to the camera to be in itself previously, and you can decide when to send the data to the back-end. 9.IP cameras and CCTV software is becoming increasingly popular meal; in addition to IP camera popularity also introduces network ball camera, network matrices, etc. Network camera development trend is to be able to support TCP, RTP, Multlcast multicast protocols, unicast protocol etc Uncast network protocol, and has high resolution and automatic conversion function day and night. In addition, through to large network power supply (PoEPower over Ethernet) and implementation of network cable 1000m long distance transmission on the LRE (Long Range Ethernet) has also been notable. 10. network monitoring system is gradually becoming a mainstream application that launched the virtual matrix switching systems-based streaming media technology network monitoring solution. Disk arrays and storage area network (SAN) and external, in conjunction with the storage (NAS) will be the ideal storage media. 11. night vision camera application through the Gulf war and the Iraq war and has opened up its mystery, thermal imaging camera can identify, within 1km in identifying vehicles within 2km in 15-track aircraft within 20km, discovery and recognition through the General objectives of disguised covertly for day and night observation and has high anti-interference ability. In addition, the emergence of the use of active infrared night vision camera system through active radiation and use target reflection infrared observation of the first to implement a night vision technology, total image resolution than through the target's own emission of infrared radiation of the thermal imaging system (usually 320 × 240 pixels).

12. Human biometric recognition began to have more practical applications. In human biometric identification system, the current distribution is a fingerprint recognition system accounts for 48 per cent, a face recognition system accounted for 14%, iris recognition system accounted for 10 per cent, voice recognition system accounts for 7 per cent, PalmPrint identification system accounted for 6%. There are also being introduced the Palm vein biometric including: hand vein recognition (Pain vein), in the enterprise, identify the dorsum (back vein), finger vein recognition (finger vein). Future, biometrics may will be the multimodal applications, instead of relying on a single technology to be identified. 13.R F I D is ready, after the 2006 global commercial company giant wall to its replacement will take the lead in the traditional bar code, but the spectrum of Division and national standards have yet to be determined. 14. the digitization, network, and intelligent will be the future of security technology development, digital monitoring software and standards will be decisive, increasingly require an open and accessible system upgrade. In the standard and universal, to be able to carry out the combination of various functional modules, can apply to a distributed network architecture, as well as be able to access the products from different manufacturers, introduced security middleware concepts and technologies, and advocates of excellent software components (Software Component) to fundamentally improve the efficiency of software production. Rising demand for Olympic security due to the international security situation is becoming increasingly complex, the Olympic host nation of the Olympic Games security inputs also rapid growth-by-session. 2004 Athens Olympic Games; Greece Government spent $ 116, used only for security has a cost of up to 15 million euros, almost equivalent to the 2000 Sydney Olympic Games, the total cost. With 325 billion deal to buy the United States international science and Technology Corporation (SAIC) of C41 (Communication ControlCommand Coordination) security system, security system set C4I command, control, communications, computers, and other functions, coordination of police, firefighters and Coast Guard, the Athens Olympics in 250 km2 area monitoring of 47 complexes, established centres of 63 instructions are on the system of coordination. Athens Olympic Games was high on the security input so is determined by the peninsula of Greece national geographic factors, as well as Greece national security capability of itself determine the conditions, during the Olympic Games in Athens, the United States and even sent the Marines and the FBI and other agencies involved in Olympic security effort. Because of the situation in China and the Olympic Games in Athens are very different and China have an independent deal with large-scale Olympics ability of Security Affairs, and the ability of the Chinese police have also adopted the Olympic torch relay and other big events. So the Beijing Organizing Committee for the external confirmation of the 2008 Beijing Olympics security expenditure budget is $ 300 million, Beijing security investment accounted for only to the overall budget of approximately 1/5. According to FBI official website data show that in the Beijing Olympic Games, Beijing Office of the FBI does not get involved in the 2008 Beijing Olympic Games security work, only in the Chinese context requirements; provide appropriate assistance to work.

Beijing 2008 Olympics security constitute requirements analysis 1. Olympic competition and training venues of security requirements. Beijing-this new 19 venues (six temporary Stadium),Reconstruction and expansion of 13, totaling 32 venues. Therefore new venue security facilities construction, as well as the original venue security facilities of perfection; and Olympic-related ancillary services facilities; and during the Olympic Games to the Olympic family members, leaders, journalists and spectators provide service areas. safety of buildings and facilities. 2. focus on the crucial goals, including the provision of services for the games of the important communication facilities. Electric hot water and other needs special protection. In accordance with the Beijing municipal science and technology to create an overall planning requirements, to the end of 2007, the city's vital parts of the body, focus areas, bustling place of science and technology create an to 100 per cent compliance, Olympic venues surrounding areas and even entire cities, all Olympic Games create security and stability of the external environment. 3. community of science and technology to create an will play. The next few years, Beijing will on 900 million square metres of damaged housing reconstruction, built thousands of new security community, all kinds of new urban residential security to comply with the specifications, as-built houses will gradually put into security building. In 2006, the city's defense, security, integration of non-safety community scale will reach 95%, Olympic adjacent communities to achieve 100 per cent. 4. establishing urban emergency system to effectively cope with the "climate, pollution, traffic, fire, earthquake, biological" major types of disaster, such as occurrence of dangerous chemicals or toxic gas leak and other emergencies, people of terrorist activity, public health emergencies and other needs emergency treatment, or services in fire protection, security alarm and other urban features to reduce urban disaster potential losses. 5. in the transport security during the Olympic Games. To this end to wipe the Olympic Lane, and strict penalties other vehicles on their discretionary consumption, you can significantly improve traffic flow during the Olympic Games. Intelligent transportation systems (ITS) and transit priority bus lane to strengthen law enforcement should not be stuck in empty.

6. implement the electronic ticketing system. E-ticket is a racy smart chip to paper tickets, and other media, used for the shortcut, prosecutorial and tickets and to enable the holder to conduct real-time and accurate location tracking and querying management. E-tickets directly with the appropriate management information system, including general audiences, key suspects, athletes, venue staff members, every Member of staff can be accurately tracked. Through the electronic ticket for authorization, you can limit persons in stadiums in every region of the access area, if that person has entered a ban on the entry area or location, monitor staff by telephone or radio notification near security staff or staff to halt, or continuous trace. Olympic video surveillance scheme selection principles Olympic selection which technology monitoring, both to meet demand and cost savings that people care about. Alternative programmes mainly IP cameras, traditional analog cameras and network video server, network-based DVR this third category. 1.DVR is a low-cost choice, but at this point you want to convert the network DVR video systems NVR (Network Video Recorder) is possible. 2. in the long term, IP camera will be more common, however, need to have real IP camera monitoring function, to use the most advanced DVR or dynamic detection systems have storage and intelligent integrated and to achieve low-cost or has unique performance advantages. 3. currently, the most realistic is the use of the existing analog system to create the desired play IP video networks. That is, to continue using your existing analog equipment, while flat camera, digital cameras, digital video recorder, PC and server directly connected to the network, analog cameras are available through the video server access to the network. In this way, the platform can be used to require video surveillance. Athens Olympic Games, with more than 700 United Kingdom Indigovision8000 codec MPEG4 compression on the audio signal and control data for transmission over IP networks, form a large IP video surveillance system. This solution is both the analog and digital systems join to solve all kinds of user environment complex security problems. Using streaming media technology to optimize the Olympic monitoring network platform although network monitoring to monitor work at any time, any place can be, but the network bandwidth is insufficient, the instability of network lines, and so often makes network monitoring in the image delay is long, image, frame rate, picture quality is unsatisfactory. While the use of Figure 7 bearing of streaming media technology, to protect the image relative good at the same time increase the compression ratio, reduced transport and storage resources. Streaming media (Streamng Media) refers to the data network by time order transmission and playback of continuous audio/video data streams. In the security industry application streaming technology, mainly for the transmission of video images, forwarding and VOD, and has the following advantages: 1. streaming media technology to monitor images, sounds, and other information from the server to the user's computer for continuous, uninterrupted transmission, users do not need to wait for all the entire file is downloaded, but only after a few seconds or 10 seconds of startup delay to watch. When sound video in the user's PC to play at the same time, the remainder of the image file will be downloaded from the server to continue.

2. streaming media technology, to some extent, the breakthrough network bandwidth for multimedia information transfer limits. For example, GIF resolution, 25 frames of a video image in real time about the bandwidth consumed 30Mbps, using streaming media technology is only the bandwidth consumed 500Kbps-1Mbps. 3. using streaming media technology that allows remote administration and centralized storage, thus ensuring the effectiveness of the monitoring system. And the use of fiber optic or coaxial cables for video transmission, has an obvious cost advantages and flexibility and expansion. Of course, in order to transfer the data on the Web, streaming video stream technology need to be addressed from audio/video source encoding/decoding to the network-media services, media streaming, the client's authorization to monitor, control and storage problems. However, with the development of broadband networksThe streaming media technology and related application has been found to be the future of high-speed broadband network for mainstream applications.
