Another important aspect, the video surveillance system can play an auxiliary role in the daily production process of the factory, and realize the unattended production line. According to the requirements of government departments and internal safety production management regulations, and in accordance with the relevant national standards, combined with the video surveillance needs of the factory to develop a network video surveillance system to achieve the following objectives: 1) video capture function: front-end video capture system to capture video and according to transmission It is required to perform compression and encoding processing, and convert into an information format that can be transmitted through the access gateway to be transmitted on the digital exchange network. 2) Video transmission function: The video information compressed and encoded is transmitted in the factory private network according to the workflow, and constitutes the transmission network system at all levels according to the security management authority. At the same time, it can meet the monitoring system management needs, transfer to the superior system and store. 3) Information processing function: Each level of system processes the received video information, etc. according to video classification and attribution, and processes the called storage information.



4) Recording storage and backup function: The monitoring center server should store, store and back up the historical data information of the video information and system log, which can be played back according to the rights in the network system.

5) System control function: According to the authorization, the control commands sent by the network user are transmitted to the front-end system, so that the monitoring center and the authorized user can call and control any one of the front-end monitoring images.

Third, system design

In modern enterprises, the factory implements a comprehensive network video surveillance system: the security monitoring part can perform real-time all-weather video surveillance on the target, plant, office building, perimeter wall, warehouse and other targets of the enterprise, and carry out all major channels and production sites in the plant. Monitoring; administrative monitoring part of the office to carry out video surveillance to understand the work of employees, strengthen employee attendance management, improve work efficiency; production management part of the production line and shipments to implement full monitoring, and timely understand the work of each workshop and assembly line Production situation. Some video images need to be kept secret, or some workshops are unattended due to the harmful effects of human health in the work environment. Remote monitoring and production can be used. Some equipments are not easy to access due to the installation location, and manual inspections are more dangerous. You can use the camera. Remote supervision; business leaders use the desktop microcomputer in the office to keep abreast of the real-time production status of each major production link, handle emergencies, and conduct two-way voice communication with the site. When going out, you can use the browser access method to enter the system and keep abreast of the production situation. The components of the monitoring system are as follows: 1. Front-end: Install a million high-definition digital cameras at each monitoring point, and select different models such as ordinary guns, infrared guns, infrared hemispheres, and high-speed balls according to the monitoring environment. 2. Transmission: According to the distance from the camera to the monitoring center, the transmission mode is selected. The distance (within 400 meters) enters the monitoring center through the network cable and the switch cascade. The remote network cable and the switch cascade and the backbone fiber and optical transceiver enter the monitoring center. . 3. Monitoring Center: The monitoring center is mainly composed of four parts, the computer room switch, the DVR host, the TV wall, and the management host. 4. Sub-control center: The sub-control center is composed of management host and display device. 5. Client: The client host accesses the camera through the client software, and supports up to 36 channels on the same screen. The signals of all the cameras on the front end are connected to the room switch. Each DVR host also accesses the switch. Each host displays 16 channels of images, and connects to the LCD TV or monitor through the VGA signal. In addition to the LCD TV connected to the DVR host, You can increase the number of TV sets (for example, add LCD splicing screens). These TVs are connected to the room switch through HD decoding boxes (each TV is equipped with a decoding box). The video data is stored in each DVR host, and different sizes of hard disks or disk cabinets need to be mounted according to the recording time. All operations of the monitoring center are realized through the management host, including image preview, screen switching on the wall, viewing host recording, and alarm linkage function as needed. Each DVR host in the monitoring center accesses the Internet through a switch. Remote users (such as superior leaders) can perform image preview, snapshot, and video recording through the client (set different permissions according to different users). System Advantages and Features The network video surveillance system is not only powerful, but also surpasses the conventional analog video surveillance system in performance. The advantages of this system are mainly reflected in the following aspects: 1.
