The Factory video surveillance system preliminary design of existing resources and the performance of the network needs to meet the front-end video capture subsystem, the monitoring center video management system construction to meet the Ministry of Public Security to carry out the views of the City Security Alarm System construction work " performance requirements, and strive to the stability of the system, reliable data storage and archiving video data on a regular basis.
First, the video surveillance system to protect the personal safety of the plant and the staff in the area of public activities, protection of production equipment and other important facilities and property, prevention of human destruction activities, and events after the accident occurred, the first time to obtain video, provide strong evidence for the timely processing and accountability. This is the basic functional requirements of video surveillance. Another important aspect of the video surveillance system in the factory daily production process, play the role of auxiliary production, and unattended production line.
According to the relevant provisions of the requirements of government departments and the internal management of production safety, and in accordance with the relevant national standards, combined with factory video surveillance needs to develop a network video surveillance system functions to achieve the following objectives:
1) video capture features: front-end video capture system captures video compression and in accordance with the transfer requirements, the encoding process converts through Access Gateway to meet the exchange online transmission of information in the digital format.
2) video transmission function: After compression, the coding processing of video information, in accordance with the workflow in a factory private network for transmission, according to the security management permission, constitute the transmission network system at all levels. Management needs to meet the monitoring system, and transfer to a higher level system and stored.
3) Information processing functions: all levels of the received video information, etc., the processing, for processing the stored information of the call by the video classification and attribution.
4) video storage and backup functions: monitoring center server data and information on the history of video information, the system log should be stored, storage and backup, network system based on permissions playback.
5) system control functions: under a license issued by the network users control commands sent to the front-end system, the monitoring center and authorized users to call and control of any front-end all the way to monitor the image.
Third, the system design
In the modern enterprise, the factory implementation of a comprehensive network video surveillance system: real-time 24-hour video surveillance security monitoring part of corporate factory gate, factories, office buildings, perimeter walls, warehouses and other goals, the main thoroughfare of the factory and produced venue monitoring; the administrative monitoring part of the office space video surveillance, to understand the staff work to strengthen employees attendance governance, improve work efficiency; governance produced throughout the implementation part of the production line and shipping monitoring, as well as when the work of each workshop and pipeline the fruit of the situation. Some video images to be kept confidential, or some workshop harmful to human health due to the working environment need unattended remote monitoring of the production process can be used; certain equipment due to the installation location is not easy to close manual inspection homework greater risk, camera remote supervision; business leaders use a desktop computer at the office, to keep abreast of all the major producing links in real time produced a situation to deal with emergencies, two-way voice communication with the site, browser access when they go out into the system the understanding produced at any time.
This monitoring system is composed of departments as follows:
Front-end: millions of high-definition digital video cameras installed in each monitoring point, according to the different models of the monitoring environment use an ordinary bolt, the infrared bolt, infrared hemisphere and high-speed ball.
Transmission: the distance to the monitoring center according to the camera select the transmission mode, the distance (400 meters) through the network cable and switch cascading into the monitoring center, the distance through the network cable and switch cascading plus trunk fiber and fiber-optic transceiver enters the monitoring center.
Monitoring center: The monitoring center consists of four parts, the engine room switch, DVR host, TV wall, the management host.
The control center: The control center by the management host, display equipment.
Client: client host through client software to access the camera, and up to 36-way with the screen display.
The front of all the cameras signal access to the engine room switch, each of the DVR access switches, display 16 images each host connected to LCD TV or monitor via the VGA signal and LCD TV connected to the DVR increase the number of TV (for example, coupled with the LCD splicing screen), these TV HD decoder box to access the engine room switches (each TV with a decoder box). The video data is stored in each DVR host, according to the recording time, you need to mount a different size of the hard drive or disk cabinet. The operation of the monitoring center management host, including image preview, the screen switches on the wall to see the host videos can also be based on the need to achieve alarm linkage. The DVR monitoring center each client through the switch access to Internet, remote users (such as superiors) image preview and capture, the video operation (set different permissions for different users).
Advantages and characteristics of the system
Network video surveillance system not only powerful in performance over conventional analog video surveillance system. The advantage of the system is mainly manifested in the following aspects:
To achieve high-quality remote video surveillance: the system is completely web-based, state-of-the-art architecture, stable performance, high quality, dynamic image processing, intelligent analysis.
Monitor the blind spot: the current network technology can support a variety of transmission line network video surveillance system through the network, you can install the camera to the network can be accessible anywhere.
Unified platform management: centralized management of diverse ways, easy to operate, fully support a common network protocol, the high degree of integration.
The recording time is unlimited, easy expansion: network video surveillance system supports centralized and distributed network storage expansion is extremely easy. On demand and expansion, storage devices can be located anywhere in the network, and the flexibility to develop storage backup strategy.
More fully utilize existing network: the rational use of the existing network resources, saving cabling costs, reduced project cycle. In addition, you can choose the Power-over-Ethernet (POE), twisted pair to provide a stable power supply.
Choice to provide more products and features: network video technology has the ability to provide a high level of integration, can be integrated with other features and services, the continuous can develop. Recognized standard protocols and information network, the system enables the integration of a large number of products has become very easy. Convert network technology means to a sustainable use of the system will invest.
Allow the system to be able to continue as a going smooth upgrade and expansion: network system is both flexible and fully scalable to meet changing requirements and expansion needs of the user. Increased monitoring front-end and the monitoring workstation plug-and-play, smooth upgrade, continued expansion anywhere deployment.
