All-angle infinite rotation single potentiometer and high-precision wind speed detection method

Abstract

The invention relates to the technical field of wind speed measurement, provides an all-angle infinite rotation single potentiometer and a high-precision wind speed detection method, and aims to solve the problem that errors are large when the wind speed is measured through pulse counting in the prior art. According to the main scheme, the potentiometer comprises a base (1) and a top cover (2), an inner carbon film ring (6) and an outer carbon film ring (5) are arranged on the base (1), the inner carbon film ring (6) is provided with an inner carbon film ring opening (6-1), the outer carbon film ring (5) is provided with an outer carbon film ring opening (5-1), the inner carbon film ring opening (6-1) and the outer carbon film ring opening (5-1) are staggered, a rotating shaft (3) is arranged in the center of an electrode holder (1), and the rotating shaft (3) is connected with the top cover (2). And an electrode plate (4) is arranged on the rotating shaft (3) and comprises an inner carbon film ring contact (4-1) in contact with the inner carbon film ring and an outer carbon film ring contact (4-2) in contact with the outer carbon film ring. And the wind speed is calculated through the rotation angle alpha of the potentiometer in unit time.

Description

technical field [0001] The invention relates to the technical field of wind speed measurement in meteorological undertakings, and provides a full-angle infinitely rotating single potentiometer and a high-precision wind speed detection method. Background technique [0002] The air is in constant motion, and the airflow generated by the air movement is called the wind. The movement of the wind has both speed and direction. It plays an important role in weather forecasting and is often widely used as a good forecast indicator. At present, wind speed collectors, which are widely used in digital networked systems of meteorological sensors, have high requirements on the accuracy and resolution of the measured wind speed data, and because they are used in meteorological services, wind speed collectors are generally installed outdoors. Long transmission distance and high measurement accuracy. According to the requirements of meteorological stations, the instantaneous wind speed is ...
