Abstract of Descriptions The present invention relates to a drone rescue device and method based on acoustic wave positioning, including a drone, a support device for a trapped person on the ground, and a ground control PC. The drone is provided with a communication module, a horn, an audio identification module at the drone side, and a sound source positioning module. The support device for the trapped person on the ground includes a wearable bracelet and a portable sound-producing device. The wearable bracelet and the portable sound-producing device are in communication connection with each other. A Bluetooth module, an audio identification device on the ground person side, and a sound-producing device control module are arranged in the wearable bracelet. The drone is controlled to hover in a search area so that the search area covers an entire target area. After an audio signal sent by the drone is identified by the audio identification device on the ground person side, the portable sound-producing device is controlled to emit the audio signal. The drone calculates coordinate information of a ground person according to the received audio signal and time delay of a microphone, performs marking, focusing and camera shooting, and transmits the information to the ground control PC.
