High-voltage transmission line video monitoring system creates a "five-remote" power safety protection network

Network News: With the development of computer technology, communication technology, power system protection and automatic control technology, the level of automated operation in the power industry has been continuously improved. At present, it has been realized that the equipment operation status and related data of the production site can be transmitted to the remote dispatching center. At the same time, the dispatching center can also control and adjust the remote on-site equipment, which is often called "telemetry", "telecommunication", "remote control" and "remote adjustment".

However, for some important power facilities, such as high-voltage transmission lines, it is far from enough to have only "four remotes". Because the dispatching center cannot intuitively understand the on-site situation, the transmission site is damaged and interfered by various man-made or natural disasters, and there is no record of video data, which cannot be timely prevented or effectively traced to the scene of the incident, resulting in immeasurable losses. Undoubtedly, if the fifth remote - "remote viewing" is added on the basis of the "four remotes" to realize remote real-time video monitoring, it can truly solve many problems of intuitive monitoring of power facilities.

For video monitoring of high-voltage transmission lines, due to the wide distribution of lines, long distances, and complex application environments, how to transmit monitoring data back to the dispatching center has become the biggest problem. Recently, Shenzhen Telikang Technology Co., Ltd. has built a multi-hop high-bandwidth wireless transmission network based on the wireless GPRSDEGECDMA3G transmission method and launched a high-voltage transmission line video monitoring system. At present, the high-voltage transmission line video monitoring system has been put into practical use in Jilin and other places. The high

-voltage transmission line video monitoring system is based on the public network wireless (GPRSDEGECDMA3G) data channel as a transmission method, and the transmission includes environmental data information, alarm data information (alarm information such as tower climbing alarm and vibration alarm), video information (line video monitoring, tower base video monitoring, infrared night video monitoring), so as to realize the online real-time monitoring of the high-voltage transmission and transformation line/tower base. At the same time, it has a powerful monitoring center, which can support real-time alarm capture pictures, real-time video, and local storage. It also has a full-duplex voice channel for intercom. At the same time, it is powered by its own solar energy to complete all-weather work and achieve the effect of real-time monitoring.

With the rapid development of the national economy, the demand for electricity in all walks of life is increasing, and the quality of power supply (stability, uninterrupted and accompanying services) provided by the power supply department is also becoming higher and higher. Therefore, the safety of the power grid operation of long-distance high-voltage transmission lines is particularly important. As a fully functional video surveillance system tailored for safe power transmission, the high-voltage transmission line video surveillance system plays an irreplaceable role in ensuring the safe operation of power.
