Problems solved by technology

[0005]The pitot tube wind speed sensor needs to use a differential pressure gauge to measure the difference between the dynamic pressure and the static pressure, and then obtain the corresponding The Pitot tube used in the Pitot tube wind speed sensor is generally longer in length and larger in size, and can only measure the wind speed in one direction, so it cannot be used in occasions where the wind direction is uncertain.

Abstract

The invention discloses an array type self-adaptive wind direction and wind speed measuring device and method. The device comprises a mounting frame, a reference air pressure sensor, an air pressure sensor array and a rotating base, the mounting frame is arranged on the rotating base; the reference air pressure sensor is arranged in the mounting frame; the air pressure sensor array comprises a plurality of air pressure sensor modules which are evenly arranged on the outer side face of the installation frame in the circumferential direction. The air pressure sensor array composed of the multiple air pressure sensors directly collects air pressure data of the multiple sensors, and has the advantages of being novel and simple in structure, small in overall size, low in manufacturing cost, large in space utilization rate, wide in application and the like.

Description

technical field [0001] The invention relates to a wind direction and wind speed measuring device and method, in particular to an array type adaptive wind direction and wind speed measuring device and 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 (including propeller type, wind cup type, etc.) Wind speed sensor and ultrasonic wind speed sensor etc. [0003] Among them, the mechanical wind speed sensor generally relies on the wind to blow a propeller or three uniform wind cups to rotate, and the Hall switch induces a magnet to output a pulse signal, which is counted by a counter and converted to obtain the actual wind speed. However, the propeller-type wind speed sensor can only measure the wind speed in a single direction; while the measu...
