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
What the present invention relates to is a kind of sensing testing device of measuring wind wind direction, in particular a kind of wind speed and direction testing device based on light spot position sensitivity.
Background technology
At present, domestic weather station major part still is the weather station of artificial observation, by manually going to read the data that measure from instrument.This just makes when measuring weather data, needs a lot of hand labors.And much places all can't install and measure instrument, thereby can't finish the automatic detection of weather condition.And along with the popularizing of computing machine, meteorological detection can realize full automation, and then automatic weather station occurs.Automatic weather station is the weather station that carries out meteorological observation and Data acquisition,, transmission under electronic equipment or computer control automatically.The appearance of automatic weather station has been saved manually a large amount of even can have been accomplished unattended meteorological the detection.At present, in automatic weather station during the measuring wind wind direction widespread use still be traditional vane and weathervane.
Traditional wind speed measuring device comprises vane and pitot tube, respectively based on machinery and aerodynamic principle.In five sixties of 20th century, heated filament (film) wind gage and laser Doppler Velocimeter have appearred successively, respectively based on heat transfer principle and Doppler effect.The particle imaging knotmeter (PIV) that the eighties grows up, its ultimate principle is the interior at certain time intervals displacement of trace particle in the measurement flow field, thereby obtains the quantitative information of flow field velocity.These mechanical hook-up volumes are bigger, cost an arm and a leg, and have often maintenance of moving-member.
Sensor develops to miniaturization in recent years, obtains very big development based on the wind speed wind direction sensor of pyrogen reason, also exists simultaneously to measure the restriction that range, power consumption and temperature such as float at the aspect.
Summary of the invention
Goal of the invention: the objective of the invention is to overcome the deficiencies in the prior art, a kind of wind speed and direction testing device based on light spot position sensitivity is provided, come the measuring wind wind direction by the light spot position sensitivity principle.
Technical scheme: the present invention is achieved by the following technical solutions, the present invention includes wind sensitive rod, light spot position detecting sensor and optical transmitting set, wherein: wind sensitive rod is vertical cantilever design, optical transmitting set is located at the unsettled end of wind sensitive rod, and light spot position detecting sensor level is located under the wind sensitive rod.
Described wind sensitive rod is a hollow structure, is convenient to the power supply of optical transmitting set.
The projection of the stiff end of described wind sensitive rod on the light spot position detecting sensor and the center overlaid of light spot position detecting sensor, described light spot position detecting sensor is circular, and the radius of light spot position detecting sensor is not less than the radius of wind sensitive rod.Can guarantee that the light that sends after the wind sensitive rod bending can also be in the valid analysing range of light spot position detecting sensor when maximum range is measured.
Described wind sensitive rod is length-adjustable wind sensitive rod, can regulate the measuring wind speed range.
Principle of work of the present invention is: by wind speed and direction being converted into mechanically deform and then realizing the measurement of wind speed and direction with the opto-electronic conversion class, wind acts on and makes it crooked on the wind sensitive rod, the optical transmitting set focused light source emits light into the light spot position detecting sensor, obtains wind speed and direction information by the light spot position coordinate that detects on the sensor.
Beneficial effect: the present invention compare with traditional proving installation have that volume is little, measuring range adjustable, easy to install and carry, low in energy consumption, temperature drift is little and be convenient to plurality of advantages such as maintenance.
