Abstract

The invention relates to a capacitive wind speed sensor and a wind speed measuring method. The capacitive wind speed sensor comprises a base, a bearing sleeve, a rotating shaft, a support, a first conductive plug steel sheet and a second conductive plug steel sheet; the bearing sleeve is arranged on the base, the rotating shaft is inserted into the bearing sleeve, the top of the rotating shaft is connected with the support, the first conductive plug steel sheet is arranged on one side of the support, a second conductive plug steel sheet is arranged on the other side of the support, a capacitance detection module is arranged in the base, the first conductive plug steel sheet and the second conductive plug steel sheet are both electrically connected with the capacitance detection module, and the wind speed is rapidly calculated through a method for measuring the wind speed through a capacitive wind speed sensor. The capacitive wind speed sensor is simple and novel in structure, low in manufacturing cost, high in detection sensitivity and simple and convenient in measurement method.

Description

technical field [0001] The invention relates to the technical field of wind speed sensors, in particular to a capacitive wind speed sensor and a wind speed measurement method. Background technique [0002] The wind speed sensor is a sensor that continuously measures the wind speed. It is widely used in the fields of meteorology, agriculture and construction machinery. According to the measurement principle, it can be generally divided into mechanical (propeller type, wind cup type) wind speed sensor, pitot tube type sensors and ultrasonic wind speed sensors, etc. [0003] The mechanical (propeller type, wind cup type) wind speed sensor generally relies on the wind to blow three uniform wind cups to rotate, and the Hall switch senses the magnet to output a pulse signal. The pulse signal is calculated by the counter technology to obtain the actual wind speed. value, but this type of sensor is greatly affected by the dynamic balance of the 3 wind cups, the weight of the wind c...
