In modern enterprises, with the implementation of video monitoring system in the factory, the security department can realize real-time and all-weather video monitoring at the gate of the factory, factory buildings, office buildings, perimeter walls, warehouses and other targets, and monitor the main channels and production sites in the factory. The administrative department can understand the work situation of employees, strengthen the attendance management of employees, and improve work efficiency, It is necessary to monitor the production and office places by video. The production management department can timely understand the working conditions of each workshop and the production situation of the assembly line, but the video image must be kept confidential. Some workshops need to realize unmanned operation because the working environment is harmful to human health, which requires remote monitoring of the production process. Some equipment are not easy to access due to the installation location, The danger of manual patrol operation is great, and the camera is needed for remote monitoring. The enterprise leaders can use desktop computers in the office to understand the real-time production situation of each main production link at any time, deal with emergencies, and conduct two-way voice communication with the scene. When they go out, they can use B / S mode to log in to the system to understand the production situation at any time.
According to the specific needs of the company to provide you with the most simple and applicable solutions, the implementation of the system in the design process mainly follows the following principles:
1. Applicability principle:
The front-end equipment has strong network adaptability: it adopts ID identification and supports DHCP, PPOE, virtual IP, etc. The front-end video server system is designed in the way of thin machine system terminal (supporting automatic upgrade of terminal device program, reducing maintenance cost and convenient function expansion). Stun server is specially designed in the background system to maximize the penetration of virtual network.
Client support B / s, C / S mode, suitable for all kinds of network environment, expand different applications, such as in the company’s website to promote the company’s products, image and so on.
System background service equipment, front-end optical equipment, support general equipment, easy to maintain and upgrade.
2. Scalability of platform construction:
Application platform, support distributed deployment, close to the user group network, reduce the pressure of the backbone network, shorten the access route, to achieve better results. Support system expansion. When expansion is needed, the early construction system can be directly connected to avoid repeated construction.
3. Meet the application needs of special industries:
Support multi-level anomaly detection alarm, send to mobile phone PHS, etc.
4. High reliability
Support 7×24 hours online service, system design should have good backup / recovery mechanism.
Strict authority authentication and management function, complete system log, perfect system backup and fault recovery mechanism.
6. Ease of use
It is required that the system is simple and easy to use, the process of obtaining service is simple, and it meets the requirements of ergonomics.
7. Make full use of existing resources
Make full use of the existing network resources, existing equipment resources, suitable and general terminal peripheral monitoring, audio and other equipment, avoid repeated investment.
According to the specific needs of your company, we will provide more detailed design scheme; The construction of the system is based on the “safe system” monitoring system platform; This paper briefly describes the connection mode of monitoring points
Design scheme 1:
1. No pan tilt fixed focus monitoring point connection mode:
2. Connection mode of fixed focus monitoring point with pan tilt:
3. Connection mode of monitoring point with pan tilt and zoom:
4. Network structure diagram of monitoring system:
Note: the figure above is the schematic diagram of the whole network structure; All the cameras in the system are surveillance cameras with pan tilt; According to the current situation of the plant, the structure is designed. On the principle of no repeated construction and saving resources, the existing monitoring equipment in the plant is connected to the monitoring system to be built through KINGHOO’s video server (DVS) to form the whole monitoring system; After the completion of the system, managers can log in to the system through C / s and B / S mode to observe the status of monitoring points, and can also conduct workshop management meetings through the system to improve production efficiency and work efficiency（ Note: the “ping an online” monitoring system can also be perfectly combined with the video conference system. After the system is implemented, it can be used independently or jointly to achieve twice the result with half the effort. If necessary, we will provide a reasonable solution).
Design scheme 2:
The scheme adopts H.264 video monitoring all-in-one machine, which is small in size, scientific research to achieve two-way voice communication, convenient and simple networking (can achieve wireless network) and suitable for indoor operation.
The network structure of the monitoring system is as follows:
Note: the effect of the video monitoring system mainly depends on the selection of the camera. In the first design scheme, the camera is optional (users can choose according to their own needs); In the second design, the selection of camera is relatively simple.
The functions of the system are as follows
Real time high-definition video monitoring of each gate;
Video recording of each point can be recorded for security check;
Effectively ensure the safe and standardized operation of the production site;
Materials and labor discipline inspection;
Real time monitoring of material handover at each gate;
By adjusting the focal length of the lens, you can clearly observe the specific details of vehicle access;
Monitor the arrival of employees at the gate during commuting;
Check the actual production labor discipline of employees at any time.
