Overhead power transmission line on-line inspection and monitoring device based on hierarchical wireless communication

The utility model discloses an overhead power transmission line on-line inspection and monitoring device based on hierarchical wireless communication. The device comprises an inspection and monitoring data receiving unit and a plurality of tower terminal units. Each of the tower terminal units comprises a power supply module, a data measurement module, and a host module. Each of the power supply modules is respectively connected with the corresponding data measurement modules and the corresponding host module. Each of the host modules comprises a data acquisition module, a microprocessor, and a wireless bridge. The data measurement modules, the data acquisition modules, the microprocessors, and the wireless bridges are sequentially connected together. The wireless bridges of the adjacent tower terminal units are connected together by Wi-Fi to form the hierarchical chain-shaped structure, and the wireless bridge of the tower terminal unit on the tail of the chain is connected with the inspection and monitoring data receiving unit. The overhead power transmission line on-line inspection and monitoring device is advantageous in that the manual line patrol can be replaced, and the problems of the wireless public network such as weak signal or no signal can be solved; the construction is easy to realize, and the later maintenance can be facilitated; the use is stable and reliable, and the costs are low; the safety management can be facilitated, the anti-damaging capability is good, and the device can be used as the emergency protection communication channel of the power network.
