Problems solved by technology

Birds pose a great threat to the safety of power transmission and transformation equipment in the power grid. In recent years, the tripping faults of transmission lines caused by bird damage and leakage of insulating porcelain bottles account for a high proportion of line fault tripping. The scientific protection of transmission lines in the power sector is also increasing. Pay attention, from organizational measures to technical measures, a lot of manpower and material resources have been invested. Traditional bird repelling equipment uses pure ultrasonic or voice to drive birds, without intelligent analysis function. This kind of bird repelling device has many shortcomings: ① Intermittent ultrasonic The method will cause environmental pollution and waste electric energy; ②The method of intermittently making threatening sounds will generate environmental noise, and it is easy for birds to adapt; ③The one with passive infrared control can only send out audio signals, but cannot automatically charge, and the maintenance cost is high; ④Not available Tower security warning function

[0011] 1) The bird repelling part of the existing high-voltage tower monitoring system cannot actively identify whether there are birds moving around the tower, and the long-term ultrasonic and threatening sounds will make the birds adapt, and the power consumption is high, the cost is high, and the environmental pollution is serious.

[0012] 2) The flashover and lightning strike positioning errors in the existing high-voltage tower monitoring system are large, time-consuming and laborious, and the specific types of flashover and lightning strike cannot be accurately judged

[0013] 3) The tower inclination detection in the existing high-voltage tower monitoring system mainly adopts the manual method, which is inefficient. Due to the large number of towers, the manual method cannot detect the inclination of the tower in time, and there is a huge potential safety hazard

[0014] 4) In the meteorological environment detection in the existing high-voltage tower monitoring system, the information of the small meteorological environment near the tower cannot be accurately obtained, and the real-time performance of the obtained meteorological information is poor

[0015] 5) In the existing high-voltage tower monitoring system, the intrusion alarm generally uses manual methods to check the line, the workload is heavy, and the tower cannot be monitored in real time, and the accuracy is poor

[0016] 6) The icing detection of transmission lines in the existing high-voltage tower monitoring system has been unable to measure accurately. The commonly used video monitoring methods are high in cost, large in error, and single in method, and cannot accurately judge various icing conditions in the harsh environment on site.

[0017] 7) The functions of each unit in the existing high-voltage tower monitoring system cannot work normally under ultra-low temperature conditions, and the ability to adapt to the environment is poor, and the monitoring work in harsh weather environments cannot be completed

[0018] 8) The power supply method in the existing high-voltage tower monitoring system generally uses disposable batteries, which cannot meet all-weather and harsh environment monitoring work, and the use environment is greatly restricted

[0019] 9) The existing high-voltage tower monitoring system works independently, and the information is generally transmitted by wire or wireless short-distance transmission, without forming a wireless network, which brings great difficulties to maintenance and monitoring work, poor real-time information and low accuracy. The monitoring center cannot accurately monitor the status of the tower
