Abstract

The invention discloses an online wind speed measurement system and a test method. The measurement system includes a test pipeline, a monitoring board, a differential pressure detection circuit, a voltage signal acquisition conversion circuit, a single-chip microcomputer, a communication module, and a receiving terminal; the test method is as follows: 1) Place the measurement system in the wind field; 2) Measure the wind speed through the detection board, and convert the wind speed signal into a voltage signal; 3) Then collect the voltage signal through the differential pressure detection circuit, and transmit it after the voltage signal acquisition conversion circuit to the single-chip microcomputer; 4) process the received concave voltage signal through the single-chip microcomputer and restore it to wind speed; 5) the single-chip microcomputer sends the wind speed signal to the receiving terminal through the communication module. The invention has simple structure, convenient test and can accurately measure low wind speed.

Description

technical field [0001] The invention relates to the technical field of wind speed monitoring, in particular to an online wind speed measurement system and a testing method capable of accurately measuring low wind speeds. Background technique [0002] At present, there are mainly mechanical, pressure, thermal, and acoustic methods for wind speed online monitoring technology. According to these test methods, corresponding mechanical rotary anemometers, pressure anemometers, thermal anemometers, acoustic anemometers, vortex anemometers, etc. have been formed on the market. However, there is a common defect in the different existing wind speed test methods: the measurement of low wind speed <7m / s is inaccurate, and effective measurement cannot be carried out for ultra-low wind speed <0.3m / s. Moreover, due to the unique gas laminar flow characteristics of low wind speed, neither the pressure type nor the thermal type can detect data or the detection is inaccurate. The mech...
