State Grid uses RFID and other technologies to monitor the condition of covers, cables and other equipment

5日,一个报警信息出现在模拟toring large screen of the Energy Big Data Center of Tianjin Binhai Power Supply Company of the State Grid: “The abnormality of the well cover of No. 18 Central Avenue”. The staff used the information collected by the big data to call the smart camera installed near the alarm work well to view the live video, and found that there were unidentified personnel to open the manhole cover, and then immediately contacted the nearby cable operation and maintenance personnel. After 10 minutes, the operation and maintenance personnel rushed to the No. 18 industrial well to recover the manhole cover, and timely eliminated the safety hazards brought to the public by the illegal opening of the manhole cover.

The pilot-installed intelligent well has an unauthorized open alarm function and a built-in acceleration gravity sensor. When the manhole cover is tilted under unauthorized conditions and the vibration exceeds this threshold, an alarm is generated and the abnormal information is fed back to the energy big data center. At the same time, the back of the manhole cover integrates the environmental monitoring terminal, and regularly collects environmental parameters such as water level, gas, temperature and humidity in the working well, which is convenient for the operation and maintenance personnel to accurately grasp the working environment and improve the efficiency of maintenance work.

Luo Kaixin, deputy director of the cable transportation inspection room of State Grid Tianjin Binhai Co., Ltd. introduced that Binhai Company actively promoted the "two networks integration" landing first test, as an important part of the cable full scene security protection system, intelligent work well and mushroom shaped cable warning pile Smart cameras work together. The cable warning pile can realize the detailed information of the cable path by scanning the RFID electronic tag through the handheld terminal. The intelligent camera has edge calculation function, and utilizes the key technology of cable line visualization protection such as automatic intrusion detection of foreign objects based on image processing technology and intelligent identification of hidden danger types, intelligent analysis and real-time warning of external damages appearing in the line channel to create civil air defense and physical defense. An efficient visual protection system for transmission lines combined with technical defense.
