Wind speed is one of the important monitoring parameters to ensure mine safety. The commonly used mine wind speed sensor can be divided into ultrasonic type, impeller type and hot wire type according to the design principle. The accuracy of the latter two methods is not high enough because they are susceptible to steam and coal dust in mines. The ultrasonic wind speed sensor has better measuring accuracy. In this paper, ultrasonic wind speed sensor, ultrasonic sending and receiving circuit combined with ADC sampling function of the chip, to obtain the received ultrasonic amplitude change data, statistics of ultrasonic waveform changes caused by blowing, according to the number of changes in the wind speed frequency, and then calculate the real-time wind speed.
