Calibration system of wind direction sensor

Abstract

The invention relates to a calibration system of a wind direction sensor, comprising a base. The calibration system is characterized in that the base is provided with a rotating disc, a photoelectric sensor, a control circuit and a driving motor; the edge of the rotating disc is provided with a plurality of through holes at equal intervals; the central position of the rotating disc is provided with a fixed hole; the transmitting end and receiving end of the photoelectric sensor are respectively arranged at the two sides of the rotating disc; and the control circuit is electrically connected with the photoelectric sensor, the driving motor and the wind direction sensor respectively; and the number of the through holes is 36. The calibration method of the calibration system provided by the invention comprises the following steps: a. firstly, judging whether signals are input or not; b. judging whether pulse signals are input or not; and c. reading a wind direction value and sending the wind direction value to an upper personal computer (PC). According to the invention, as the driving motor and the photoelectric sensor are arranged, automatic calibration of the wind direction sensor is realized, and the speed and accuracy of calibration are increased; and for the calibration method provided by the invention, data acquisition is completed automatically, so that the original fussy mode of manual reading is changed.

Description

technical field [0001] The present invention relates to a wind direction sensor calibration system, more specifically, to a wind direction sensor calibration system which can automatically complete the detection of the wind direction sensor. Background technique [0002] Modern society has higher and higher requirements for automation, but in recent years, the calibration of wind direction sensors has largely remained at the manual calibration stage. This calibration method is time-consuming, has low calibration efficiency, and is prone to false readings. Therefore, it is necessary to design a system for automatically calibrating the wind direction sensor. Contents of the invention [0003] In order to overcome the disadvantages of the above-mentioned technical problems, the present invention provides a wind direction sensor calibration system that can automatically complete the detection of the wind direction sensor. [0004] The wind direction sensor calibration system ...
