A practical port monitoring system (photo) (1)

I. preface

1.1 description

With the development of the society, port security monitoring has become a port of a weak current construction important aspects, this article describes a practical port monitoring system.

The programme is designed to simulate the way as the basis, as well as digital system, application modernization of monitoring equipment technology, surveillance video image control, storage, transport, query into unified management, both complementary and mutually reinforcing, jointly build a practical, quick port monitoring system in order to protect the security of the port.

This monitoring system form as shown in the following figure, is divided into front end device, signal transmission device, Center video switching control device.

System main equipment are international famous brands of equipment, with circuit breakers, short-circuit, disassembly and Assembly can be warning function.

1.2 design basis

According to the user's specific requirements, we believe that taking digital images to the core multimedia computer closed circuit monitoring alarm system has become mainstream, Digital hard disk video set screen divider, video switch, tape recorders of all functions, itself can connect alarm detector, alarm, video mobile reconnaissance, through the decoder control pan/tilt and lens, you can also transfer images over the network and control signals, implement in control management.

1.3 design principles

Monitoring system for the purpose in addition to maintaining the security of the port, another purpose is to serve the management, to provide modern tools of management.

Control system design is guided by the following principles, in order to achieve the best results and optimal cost performance.

1. applicability:

System design should meet the needs of the port management, such as video motion detection and control of the cloud, provisioning, etc.

In addition to these features, there are audio and video recording, alarm systems and monitoring systems of linkage, and other useful features.

2. Advanced:

The system must be adapted to scientific and technological development in the direction of certain extraordinary scalability in the development process can continue to expand, with considerable development potential in choice of equipment should be implemented in the system after some years, also able to maintain their perfect function, complete, and not backward.

3. reliability:

All use of the technology and equipment must have been certified as "mature and object-oriented engineering", you need to take full account of the construction of situations that may occur to avoid various unstable factors, ensure that the quality of the project.

4. efficiency:

Port system application monitoring system for the ultimate goal is to increase the intensity of the port supervision of safety, the maximum savings in manpower, thereby enhancing the regulatory efficiency, reduce the labor intensity.

Therefore the system should be designed to fully embody the "police" the technology to design principles to ensure the effective and efficient operation.

II. system analysis and solution

2.1 system topology and layout design

As smart as an important component of the port, monitor and control more and more applications in the port of informatization, the container terminal operation managers understand the important areas of real-time access to first-hand the image information, greatly improving the management of a rapid reaction capability.

The entire system structure as shown in the figure below.

2.1.1 monitoring system front side camera selection and places:

In the yard of four high pole lamp installed four, in the parking lot at installation on high pole a fast ball camera, consider using the United States DISCOVER famille high-resolution low illuminance of high-speed fast ball camera DIS-9000SD, it meets vision monitoring and meet close-range monitoring, horizontally 360 °, vertical flexible fast rotation 180 °, monitoring, timely, fast-tracking of moving objects.

It has a progressive scan processing, and conversion, cumulative, and wide dynamic frame technology that provides full 24 hours monitoring, able to render all day and all night out of high-definition and vivid image. Yard east of the installation of two zoom air gun camera to monitor yard quick ball camera exposure to two cargo between location and assembling the head, while monitoring the yard east of the channel. Yard northeast corner and office building with a roof top gun, Minister Coke port three piers and complex surrounding comprehensive monitoring.

Color selection of gun-type camera DIS-539EX with Japan COMPUTAR company electric zoom lens H30Z1015AMS (30 x zoom) to reach the entire phase of the port area of Omni-directional, barrier-free zone of control.

In the port of gate gate settings 1 road dedicated camera DIS-529EX, dedicated to filming and out of the vehicle. In order to protect the camera does not directly be struck by lightning in the strong electricity import distribution Chamber, we will use 10 power surge arrester (Ann Shijie SV-3/220) protected outdoor 10 camera power supply for protection.

A total of five-storey office tower, a Foreign Office Hall, set two colour constant speed dome camera DIS-RD2200 for travellers visiting the Hall.

Is set to take on an office door one day DIS-539EX, record all into the Hall. Due to the building as a Prism-type, floor, or so long, the second layer to layer on each floor two bolt, 8 Department DIS-208C. In addition to internal office building, the building after work may go off corridor lamp, consider building camera equipped with infrared light, darkness in the State of implementation monitoring of the video.

Recommends that the Office building of the elevator in the small elevator camera.
