Abstract

An array silicon pressure all-weather wind power sensor comprises four silicon pressure sensor sets, a disconnection silica gel protection layer, a directional gyro, a temperature sensor, a control unit, a USB and a concentrator.Each silicon pressure sensor set is composed of 12 silicon pressure sensors, a CMOS signal processing circuit and a temperature compensation circuit and is in a rectangular shape.The disconnection silica gel protection layer is used for conducting wind power and used for protecting the silicon pressure sensor sets.The directional gyro is used for indicating directions and sending directions to the control unit.The control unit is used for receiving 48 pressure signals sent by the four silicon pressure sensor sets.Raindrop signals and wind power signals are distinguished according to the pressure signals; when the array silicon pressure all-weather wind powder sensor sets form a cuboid, the current wind power direction and forward wind power are calculated according to wind power of the four faces and the directions indicated by the directional gyro; the array silicon pressure all-weather wind power sensor is used for storing error compensation and non-linear error and environment temperature additional error compensation caused by vibration impact of the silicon pressure sensor.

Description

technical field [0001] The invention relates to the technical field of silicon piezoresistive pressure sensors, in particular to an array type silicon pressure all-weather wind sensor. Background technique [0002] Wind force refers to the magnitude of the force shown by the wind blowing on an object. Generally, according to the various phenomena produced by the wind blowing on objects on the ground or water surface, the wind force is divided into 18 levels, the minimum is 0, and the maximum is 17. [0003] Wind speed is the forward speed of the wind. The greater the air pressure difference between two adjacent places, the faster the air flows, the greater the wind speed, and the greater the force of the wind. Therefore, the wind force is usually used to express the size of the wind. The unit of wind speed is expressed in meters per second or kilometers per hour. When issuing weather forecasts, most of them use wind scales. [0004] In order to measure the wind force mo...
