Industry Overview

With the comprehensive transformation of the power network, all substations and substations are required to achieve unmanned operation to improve production efficiency. At present, the power bureau has established an operation management duty room and dispatch department, but cannot timely grasp the operation status and command the handling of operation obstacles. The main issues are as follows:
1. Dispatch and command operations rely entirely on telephone contact, making it impossible to provide guidance for on-site operations and predict the situation of on-site operations; Due to the inability to ensure on-site safety, unmanned substations still rely more on manned methods; 
2. The use of operation team inspection methods cannot guarantee timely detection and handling of equipment hazards, and can only be handled after the fact, which affects the power supply reliability of the power bureau to meet the standard; 
3. The scheduled inspection method is largely an unreasonable allocation of resources; 
4. The security requirements for power communication are very high, but currently many computer rooms in power communication are in an unmonitored state, which is a great hidden danger to the security of power communication. Therefore, most computer rooms adopt a manned mode, which is difficult to maintain and monitor in some remote areas. 
Therefore, establishing a technologically advanced and powerful monitoring system has been put on the development agenda of the power sector. The power monitoring system establishes a monitoring center in the power dispatch communication center to monitor and monitor relevant data, environmental parameters, and images of each substation and substation, so as to be able to understand and grasp the situation of each substation and substation in real time and directly, respond to the situation in a timely manner, and adapt to the development needs of modern society. 
Considering the application characteristics, environment, and requirements of the industry, the monitoring points are scattered and far apart, making it inconvenient to lay network cables or optical fibers. At the same time, there are a large number of monitoring points, and county and city power supply bureaus need to view images from multiple monitoring points, so the bandwidth requirements for wireless systems are very high. At the same time, the equipment needs to meet the requirements of stable and reliable operation in harsh outdoor environments. Combining these characteristics, wireless video surveillance solutions are an ideal choice. 

Wireless video surveillance system implementation functions:
The wireless monitoring system for unmanned computer rooms in the power industry is mainly used to monitor the real-time operation status of equipment in the computer room (such as power supply and distribution systems, UPS power supplies, air conditioning, fire protection systems, security access control systems, etc.), the environmental and dynamic status of equipment operation, and record historical data. It realizes the remote control management function of the power computer room, making the monitoring of the power industry computer room unmanned or less manned, and providing strong guarantees for the efficient management and safe operation of the computer room. The system can be divided into three parts: front-end collection and processing, data transmission, and back-end monitoring and management. The effective combination of the three ensures that the system can transmit real-time, fast, and accurate images and data of the substation back to the monitoring center. 
Industry characteristics and equipment selection:
1. The scope involved is wide and the distance is far. The monitoring points are far away from the monitoring management center and distributed in a scattered manner. Therefore, it is necessary to choose a wireless bridge with a longer transmission distance. 
2. Generally, the data and image information collected by the village power station need to be summarized to the township power station first, and then transmitted back to the county power station by each township power station. Therefore, it is required that the wireless devices installed at the township power station and county power station provide a large bandwidth to meet the bandwidth requirements for transmission services and ensure the stability of the wireless link. 
3. Some monitoring points are not visible from the monitoring center and there is obstruction in between, requiring the installation of relays. 
4. It is required to monitor the video images and automated control data collected from all monitoring points in real-time around the clock, with extremely high stability requirements for wireless links. Therefore, it is necessary to require the device to have high receiving sensitivity, large bandwidth, and good stability performance. 
5. Considering the large number of monitored images, the management method of the monitoring center should be simple, clear at a glance, and have low management costs. 
6. The system has great flexibility, and newly added monitoring points can easily connect to existing wireless networks, requiring strong scalability. 
The confidentiality requirements for wireless networks are high. 
When collecting automation control data, in order to achieve business transmission, it is necessary to use an Ethernet to serial converter to convert all collected data into IP packets for wireless transmission.
