Abstract

The invention relates to an ultrasonic positioning device for unmanned aerial vehicles and a positioning method thereof. The positioning device comprises an ultrasonic transmitting unit installed on atransmission line tower and an ultrasonic receiving and positioning unit installed on an unmanned aerial vehicle. The ultrasonic transmitting unit comprises a regular polyhedral ultrasonic transmitting array, a transmitting array controller, a solar cell panel and a storage battery connected in turn. The ultrasonic receiving and positioning unit comprises an L-shaped ultrasonic receiving array, an ultrasonic acquisition unit and a signal processing and positioning module connected in turn. Through the special design of the ultrasonic transmitting array and the receiving array, the communication between the transmitting part and the receiving and positioning part is not needed. The transmitting part transmits signals all the time, and the receiving part installed on the unmanned aerial vehicle can complete positioning only by receiving signals. Therefore, positioning is realized efficiently.

Description

technical field [0001] The invention belongs to the field of multi-rotor unmanned aerial vehicles, and relates to spatial positioning of unmanned aerial vehicles, in particular to an ultrasonic positioning device and a positioning method of a multi-rotor unmanned aerial vehicle for patrolling power transmission lines. Background technique [0002] With the gradual expansion of the scale of the power grid and the rapid increase in the amount of transmission line equipment, the traditional manual inspection can no longer meet the demand, especially in the western region of my country, where there are many mountains and rivers, the workload of manual inspection is difficult, and the inspection efficiency is low. [0003] In recent years, the UAV intelligent inspection technology has developed rapidly, and it is not affected by the terrain. It patrols along the transmission line, which greatly improves the inspection work efficiency, and the UAV can carry different advanced airbo...
