Aiming at influence of damp and dust under mine on inaccuracy of measurement of domestic wind instruments

put forward a smart multi-channel wind speed and direction equipment for mine. Its system software is designed by multi-platform module

using multi-stage fitting for measurement parameter error correction and ultrasonic sensors

dry wet temperature sensor

pressure sensor

signal conversion circuit are integrated on handheld terminal

realize multi-channel

fast and accurate measurement and autonomous calibration of instrument parameters. Compared with the test results of the traditional instrument

the average test error of this intelligent instrument is only 2. 47 % under the national standards

and the measuring effect and its stability is significantly higher than the traditional mechanical wind equipment.
