Embodiment Construction
[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0032] The UAV line inspection detection system realizes line inspection monitoring and detection operations through the cruise system, information collection system and data remote transmission system. Its overall structure is as follows: figure 1 shown.
[0033] The cruise system first uses GPS or 4G network base station positioning technology for rough positioning, and then achieves a more accurate and reliable cruise effect through non-coplanar MIMO relative positioning and radio frequency tag array positioning. The wireless reader on the UAV remotely activates the radio frequency tags on the route, and determines the relative distance according to the signal arrival time TOA fed back by the radio frequency tags. There is a time difference of arrival (TDOA) in time, from which the relative ball angle can be calculated, and then the relative ...
