Any accident in any link may cause a chain reaction, resulting in large-scale power outages, personal injury, damage to main equipment, and even catastrophic accidents such as the collapse of the entire network. Therefore, the detection of the power system is the top priority in the power system of the Internet of Things. Generally, it is operated manually at high altitudes, and safety issues are difficult to guarantee. In the high temperature conditions of summer, the problem becomes particularly prominent. In addition, this kind of high-altitude transmission line is very long, and manual operation has great limitations. The observed problem information is not very comprehensive.
