On November 19, on the online monitoring platform of the transmission line of the State Grid Shaanxi Electric Power Company, the monitoring personnel can intuitively learn the peripheral environment of the Shaanxi section of the Changji-Guquan ±1100 kV UHV DC transmission line project at the touch of a finger. The inspection benefited from the smart power transmission video surveillance system successfully deployed by the company in cooperation with Huawei Technologies Co., Ltd. and Zhiyang Innovation Technology Co., Ltd., which realized the full automatic collection, efficient transmission and intelligent identification of hidden dangers of transmission line channels and operating environment.
The Shaanxi section of the Changji-Guquan ±1100 kV UHV DC transmission line project is located in the uninhabited area of the Qinling Mountains. The terrain is complex and the roads are rugged. The safety of the line channels has become an important factor affecting the reliable operation of the power grid. At the same time, because the unmanned area does not cover the mobile base station signal, it is impossible to obtain the image of the transmission line, micro-weather and ice coating in time. How to solve this problem, improve inspection efficiency and reduce the rate of missed inspections, has become a major problem that plagues high-quality operation and maintenance of transmission lines.
"This time we jointly solved the communication problem of overhead transmission lines in unmanned areas. Through these technologies, even if the poles and towers are in high mountains and the terrain is complex, the on-site operating conditions, images, videos, and meteorological units can still be transmitted back. The safe operation of our transmission lines provides a pair of eyes with a high recognition rate to ensure timely monitoring of on-site conditions and achieve controllability." After the company deployed a smart power transmission video monitoring system, Kong Zhizhan, director of the transmission department of the company's equipment department, said excitedly.
This set of smart power transmission video monitoring system adopts the technical solution of smart power transmission line in non-signal area based on 5G microwave private network. Luo Yanhong, deputy director of the Guanzhong Operation and Maintenance Division of Shaanxi Maintenance Company, introduced: “This program uses five types of terminals to cooperate to meet the transmission line monitoring needs of non-signal areas in areas without communication signal coverage." This scheme can not only create data for areas without signal. The transmission channel returns the data of various online sensors installed in the no-signal zone to the background, and the terminal equipment can be installed within 30 minutes by only 2 people, and it can also be upgraded and debugged remotely, which has a wide range of applications.
Another bright spot in the Shaanxi section of the Changji-Guquan ±1100 kV UHV project is the use of Huawei's self-developed low-power and high-computing AI module Atlas 200. The front-end monitoring device combines Atlas 200 to intelligently analyze the collected pictures, and can automatically identify large construction machinery such as cranes, excavators, cement pump trucks, bulldozers, as well as pictures of hidden dangers such as mountain fires and smoke. Upload the background in time to improve the detection of hidden dangers Efficiency and accuracy. At the same time, the monitoring video frequency is increased to once per minute, real-time monitoring, reducing communication dependence. In addition, the line patrol UAV loaded with Atlas200 can realize real-time warning, which greatly improves the inspection efficiency.
The application of the smart power transmission video monitoring system is part of the construction of the ubiquitous power Internet of Things by the State Grid Shaanxi Electric Power Company. The company’s equipment department will use the system to continue to explore smart and efficient inspection modes and contribute to the construction of the ubiquitous power Internet of Things .
