Solid state wind sensor

Abstract

The invention provides a solid state wind sensor, comprising a windward cylinder, a wind-guiding component and a sensor set, wherein the wind-guiding component is installed at the lower part of the windward cylinder, and comprises a left side portion and a right side portion; the inner sides between the left side portion and the right side portion form an accommodating space, and each sensor in the sensor set is fixed in the accommodating space. The outside of the windward cylinder is provided with a plurality of windward minipores, and wind-guiding channels are formed in the windward cylinder and the wind-guiding component to correspond to the windward minipores; under wind pressure, the windward minipores are conducted to corresponding wind-guiding pipes of corresponding sensors in the sensor set through corresponding wind-guiding channels. The solid state wind sensor transmits pressure difference through a housing channel, so as to eliminate the flexible pipe between a wind sensing component and a pressure difference sensor, thereby substantially reducing the size of a pressure difference type solid state wind sensor, and improving solid state wind sensor ageing resistance.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a solid-state wind sensor. Background technique [0002] Wind speed and wind direction are important meteorological parameters, which are of great significance to people's daily life, meteorological environment, national defense aviation, industrial and agricultural production, and transportation. Therefore, wind speed and wind direction measuring instruments have been widely used in many occasions. [0003] There are many kinds of wind speed and wind direction measurement principles and corresponding measuring instruments. Among them, the mechanical wind speed and direction instrument is the standard for meteorological observation, which is composed of a wind cup anemometer and a wind vane. In the wind cup anemometer, there are three or four hemispherical or parabolic empty cups, which are evenly distributed along one side to form a rotating structure. Under the action of wind f...

Problems solved by technology

[0006] However, for figure 1 In the solid-state two-dimensional anemometer shown, the wind sensing part and the differential pressure sensor are connected by a hose, which hinders the further reduction of the volume of the anemometer, and the existence of the hose reduces the anti-aging performance of the anemometer
