This paper designs a land air integrated inspection and control platform for converter stations based on inspection data integration. In the Hardware part, LKT4304 encryption chip, DJI Mavic Mini Drone FlyCam UAV and Hardware security chip are designed. In the software part, based on the patrol data integration, the air-land integrated patrol control route of converter station is planned, and the air-land integrated patrol control logic of converter station is generated, thus realizing the air-land integrated patrol control of converter station. The test results of the platform show that the designed integrated patrol management and control platform for land-air patrol data of converter station has good performance, and all functional modules are running in order, which is reliable and has certain application value, and has made certain contributions to improving the operation safety of converter station.
