Design Principles of Ultrasonic Wind Speed and Direction Instrument Based on POE Power Supply

ultrasonic testing equipment can avoid problems of traditional wmd speed and wind direction test equipment, such as low accuracy and short life, ultrasonic wind speed and direction instrument based on the POE power supply utilizes ultrasound transmission characteristics to achieve the measurement of wind speed and direction of three-dimensional space, and provides a new power supply mode for remote monitoring equipment, thereby solving problems of complex route, communication signal attenuation and the like due to long distance of communications and power supply. The paper introduces the power supply principle, core control and measurement data transmission principle, and mechanical structure principle with adjustable angle of ultrasonic wind speed and direction instrument based on POE power supply.
