Wind speed and direction testing device based on light spot position sensitivity

Abstract

The invention discloses a wind speed and direction testing device based on light spot position sensitivity, comprising a wind-sensitive rod, a light spot position detection sensor and a light emitter, wherein the wind-sensitive rod is of vertical cantilever structure; the light emitter is arranged at the suspended terminal of the wind-sensitive rod; and the light spot position detection sensor is horizontally arranged below the wind-sensitive rod. Compared with the traditional testing devices, the testing device of the invention has the advantages of small volume, adjustable range, convenient installation or carrying, low power consumption, small temperature drift, convenient maintenance, etc.

Description

technical field [0001] The invention relates to a sensing test device for measuring wind speed and direction, in particular to a wind speed and direction test device based on light spot position sensitivity. Background technique [0002] At present, most of the weather stations in China are manually observed weather stations, and the measured data are read from the instruments manually. This makes the measurement of meteorological data requires a lot of manual labor. And measuring instruments cannot be installed in many places, so that the automatic detection of meteorological conditions cannot be completed. With the popularity of computers, weather detection can be fully automated, and then automatic weather stations appear. An automatic weather station is a weather station that automatically performs meteorological observation, data collection, and transmission under the control of electronic equipment or computers. The emergence of automatic weather stations saves a lo...
