Problems solved by technology

[0005] In view of the deficiencies in the prior art, one of the purposes of the present invention is to provide a method for efficiently collecting big data of the power grid, which solves the problem that the inspection of transmission lines mainly relies on periodic inspections by operation and maintenance personnel. Although hidden dangers of equipment can be found, due to its own limitations , lack of detection of special environment and climate, and the change of external force in the line corridor cannot be grasped in time during the vacuum period of the patrol cycle, and it is very easy to cause line accidents due to lack of monitoring before the next patrol. In order to achieve the above objectives, the present invention adopts the following technical solutions To achieve:
