Abstract

An unmanned aerial vehicle rescue device and method based on sound wave positioning, comprising an unmanned aerial vehicle, a supporting device for persons trapped on the ground, and a ground control PC. Source locating module, supporting devices for trapped persons on the ground include a wearable wristband and a portable sounding device, and the wearable wristband and the portable sounding device are connected for communication. The wearable wristband is equipped with a Bluetooth module, an audio recognition device and a sounding device for ground personnel. The control module controls the drone to hover at the interval of the search area, so that the search area covers the entire target area. After the audio signal sent by the drone is recognized by the audio recognition device on the ground personnel, it controls the portable sounding device to send out the audio signal. The man-machine calculates the coordinate information of the ground personnel according to the received audio signal and the delay of the microphone, marks and focuses the camera, and transmits the information to the ground control PC.

Description

technical field [0001] The present invention relates to the field of emergency rescue, in particular to a UAV rescue device and method based on acoustic wave positioning. Background technique [0002] The geographical environment of electric power field work is complex, a large number of equipment are in mountainous areas, the terrain is complex, the natural environment is harsh, and many mountainous areas are even uninhabited areas, which brings many difficulties to the operation and maintenance of electric power equipment Risks to personnel: With the continuous construction and development of the power grid, the number of power equipment under the jurisdiction of each person continues to increase. Finding the path in the field is not only time-consuming and labor-intensive, but may also get lost, which poses certain safety hazards. In field operations, there is often no communication signal, which leads to personnel losing contact. The search and rescue is very difficult. ...
