Abstract

The invention discloses a control method and a device for an ultrasonic receiving device. The control method comprises the following steps of determining a target receiver of the ultrasonic receivingdevice, wherein the ultrasonic receiving device comprises at least two ultrasonic receivers, and the target receiver is one of the ultrasonic receivers which directly faces an ultrasonic transmittingdevice on the ultrasonic receiving device; according to the determined target receiver, controlling the state of each ultrasonic receiver on the ultrasonic receiving device. Therefore, the error of ultrasonic ranging is reduced, and the measuring accuracy is improved.

Description

technical field [0001] The present application relates to, but is not limited to, ultrasonic technology, and particularly relates to a control method and device for an ultrasonic receiving device. Background technique [0002] Ultrasound is a part of the sound wave, which is inaudible to the human ear and has a frequency higher than 20KHZ (kilohertz); the propagation of ultrasonic waves has the characteristics of strong directivity, slow energy consumption, and long propagation distance in the medium, so ultrasonic waves are often used in distance measurement. [0003] An implementation of ultrasonic ranging includes an ultrasonic transmitter and an ultrasonic receiver, and the difference between the time when the ultrasonic receiver receives the ultrasonic signal and the time when the ultrasonic transmitter sends the ultrasonic signal is multiplied by the propagation speed of the ultrasonic signal to obtain Distance between ultrasonic transmitter and ultrasonic receiver. ...
