Digital crosswind sensor for monitoring wind speed and wind direction of crosswind

Abstract

The invention relates to a digital crosswind sensor for monitoring the wind speed and the wind direction of crosswind, comprising a probe, a differential pressure sensor, a temperature sensor, a microprocessor and a signal conversion interface, wherein a differential pressure signal is sensed by the differential pressure sensor according to the air pressure change caused by ambient air flow of a part to be measured, converted into a corresponding air speed value according to a certain formula and transmitted to an upper computer through a signal conversion interface for display; the differential pressure sensor has the advantages of high sensitivity and high measurement precision due to the adoption of a micro-electronic chip; the temperature sensor is used for monitoring ambient temperature changes in real time and further converting the changes into an air density value under a corresponding condition so as to correct the air density value in real time, thereby overcoming the defect that the temperature sensor is greatly influenced by the ambient temperature and has lower measurement precision; the microprocessor has strong vibration and interference resistance by using a digital filtering algorithm; the signal conversion interface has good expansibility; and in addition, the used part is formed by assembling small-packaging low-power consumption electronic devices, and has small size and low power consumption.
