Abstract
The utility model discloses an ultrasonic wind speed and wind direction measuring device belonging to the field of wind speed and wind direction measuring device. The measuring device comprises a wind-sensitive rod, an ultrasonic emitter and at least three ultrasonic receiver, wherein the wind-sensitive rod is of a vertical cantilever structure; the ultrasonic emitter is fixed at the overhanging tail end of the wind-sensitive rod; the three ultrasonic receivers are fixed on a base in the form of equilateral triangle; the base is horizontally arranged below the wind-sensitive rod; and the projection of the fixed end of the wind-sensitive rod on the base and the center of the equilateral triangle consisting of the three ultrasonic receivers are superposed. In the utility model, only one ultrasonic emitter and three receivers are used for achieving the aims of measuring the wind speed and the wind direction; compared with the prior art, the measuring device has simple structure; furthermore, by adopting the wind-sensitive rod, the distance from the ultrasonic emitter to the ultrasonic receivers is not changed under the blowing of the wind, thus greatly reducing the volume of the measuring device and improving the measurement sensitivity.
Description
Technical field
The utility model relates to a kind of device of wind speed and direction field of measuring technique, in particular a kind of ultrasonic wind speed and direction measuring device.
Background technology
The measurement of wind speed and wind direction all has great significance in numerous fields, uses as environmental monitoring, air handling system and industrial or agricultural.The air velocity transducer of using in measuring wind speed mainly contains mechanical type, hot type and non-hot type etc.
But these air velocity transducers all respectively have shortcoming: the big and damage easily of the structure of mechanical vane weathervane; The hot type air velocity transducer is subjected to the influence of environment temperature and humidity big and power consumption is big; Ultrasonic air velocity transducer emission of typical case and detection receive a stationkeeping, and therefore structure is bigger relatively.
In the last few years, some novel air velocity transducers were developed.Advantages such as it is little to have a volume based on the miniature current velocity sensor of micro electronmechanical (MEMS) technology, and price is low are to study focus recent years, but MEMS hot type air velocity transducer have power consumption big, exist temperature to float, shortcoming such as sensitivity is low.In addition, traditional ultrasonic wind speed sensor measuring system also has shortcomings such as volume is big.
The utility model content
The utility model purpose: the purpose of this utility model is to overcome the deficiencies in the prior art, a kind of ultrasonic wind speed and direction measuring device is provided, ultrasonic transmitter is fixed in the end of wind sensitive rod, wind sensitive rod can depart from the position when static when the wind action lower swing, thereby can change the distance of transmitter to three receiver, can improve sensitivity greatly.
Technical scheme: the utility model is achieved through the following technical solutions, the utility model comprises wind sensitive rod, base, ultrasonic transmitter and at least three ultrasonic receivers, wherein: wind sensitive rod is vertical cantilever design, ultrasonic transmitter is fixed at the unsettled end of wind sensitive rod, ultrasonic receiver is being fixed on the base of equilateral triangle, the base level is located under the wind sensitive rod, the projection of the stiff end of wind sensitive rod on base and the center overlaid of the equilateral triangle formed of three ultrasonic receivers.
Described base is a disc-shaped base, and described base radius is not less than the radius of wind sensitive rod.
Principle of work of the present utility model is: ultrasonic transmitter and three receivers have constituted a tetrahedron, and wherein three ultrasonic receivers are the equilateral triangle distribution, and their position can not change; The position of ultrasonic transmitter changes along with the swing of wind sensitive rod.Like this, the distance of ultrasonic transmitter to three ultrasonic receiver just can change, by measure ultrasound wave from ultrasonic transmitter to each ultrasonic receiver travel-time or mistiming of each ultrasonic receiver just can be regarded as distance, thereby learn the angle of wind sensitive rod inclination and the direction of inclination, and then record wind speed and direction.
Beneficial effect: the utility model only with a ultrasonic transmitter and three receivers just reached can measuring wind the also purpose of energy measurement wind direction, compared with prior art, not only simple in structure, and owing to adopted wind sensitive rod, ultrasonic transmitter can be taken place in the wind to the distance of ultrasonic receiver, thereby can reduce volume widely and improve measurement sensitivity.
