Centralized monitoring system and monitoring method for unmanned aerial vehicle to patrol power transmission line

Disclosed is a centralized monitoring system for an unmanned aerial vehicle to patrol a power transmission line, comprising a centralized monitoring subsystem, mobile substations and unmanned aerial vehicle flying platforms. The centralized monitoring subsystem is connected to the mobile substations in a one-to-many manner, and the mobile substations are connected to the unmanned aerial vehicle flying platforms in a one-to-one manner. By combining remote centralized monitoring with local monitoring, centralized monitoring is conducted on information about the flying state of more than one line-cruising unmanned aerial vehicle, the pod state, the power transmission line, the patrol result and the like, personnel, devices and patrol lines related to patrol tasks of the unmanned aerial vehicle are planned and managed, and centralized management and fault diagnosis are conducted on the patrol result, to enhance the degree of informationalization and automation of the patrol process and patrol result processing of the unmanned aerial vehicle, to improve the patrol efficiency of the unmanned aerial vehicle, and to provide technical support for realizing the secure and reliable operation of the line patrol of the unmanned aerial vehicle.
