Description
Technical field
The utility model relates to a kind of ultrasonic wind speed measurement mechanism, especially a kind of self calibration ultrasonic wind speed measurement mechanism of accurately measuring wind, wind direction.
Background technology
In the past, the measurement for wind speed and direction was to adopt the mechanical type anemoclinograph that is comprised of vane, weathervane, blade basically.The mechanical type anemoclinograph not only in use is subjected to the environmental restraint such as low temperature, sand and dust, and also wear and aging very easily of its mechanical part, can't guarantee to move reliably and with long-term, its measurement range narrow (2 ~ 40m/s), error large (greater than 2%) and can not measure instantaneous wind speed.What generally use at present is ultrasonic aerovane for this reason.Ultrasonic aerovane is compared with mechanical anemometer, does not contain moving component, the machinery-free wearing and tearing, and reliability is high, long service life; Good environmental adaptability can satisfy the use of the rugged surroundings such as dust storm, high low temperature (40 ~ 70 ℃) and can measure instantaneous wind speed; Precision is relatively high, and measurement range is large, has been widely used in the fields such as environmental monitoring, wind-powered electricity generation, meteorology, tunnel, navigation, aviation.
The point-to-point time difference method measuring wind of the general employing of existing ultrasonic aerovane.Hardware configuration is to be provided with the MCU control module, be connected to ultrasound emission module, probe temperature sensor, heating module and communication module with the MCU control module, ultrasonic receiver module joins by Echo Processing module and MCU control module, is connected to the ultrasonic probe group (many to ultrasonic probe) of same one dimension A, the B that can be installed in one dimension (X), bidimensional (X, Y) or three-dimensional (X, Y, Z) at 2 with ultrasound emission module and ultrasonic receiver module.Method of testing is ultrasonic transceiver module after starting, and obtains to come back the travel-time (Tab, Tba) at same one dimension (X, Y or Z) ultrasonic wave propagation path, again according to formula
Calculate the component (D be ultrasonic probe spacing) of vector wind on one dimension/bidimensional/three-dimensional, obtain bidimensional/three-dimensional velocity under the conventional coordinates through the vector compose operation, and calculate wind direction θ with the trigonometric function method, by communication module output wind speed and direction.When existing anemoclinograph is installed, use north arrow to adjust the wind direction initial point and align with south/north, orientation, measure azimuthal error because installation process exists, with software adjustment compensate again after needing to install for this reason.Set probe temperature sensor is the detection probe temperature in good time, by heating module control probe temperature.There are the following problems for existing ultrasonic aerovane:
1. because the D in the formula is invariable design load (preset value), therefore the precision that the wind speed precision depends on probe spacing of surveying changes then thereupon proportional variation of measured air speed error in processing, assembling or use procedure such as probe spacing;
2. software adjustment compensating operation is loaded down with trivial details after installing, and wastes time and energy.Particularly anemoclinograph is being installed such as sports equipment tops such as car and boat, mobile platforms, the wind direction angle can move and conversion with equipment base, redirects not only that trouble also causes error easily, the impact precision that determines the wind direction.
