Problems solved by technology

[0003] Transmission line online monitoring devices are generally composed of a main control unit, a power supply unit, and a sensor (image, video) unit, but the existing detection devices still have the following problems: 1. Online monitoring devices often use operator-based mobile networks for communication, According to different transmission types, different communication modules are selected, but in some remote mountainous areas, the operator's signal cannot be covered at all, resulting in low reliability of the line operation; The failure will cause the other sensors to fail to collect normally at the same time
