Description
Technical field:
The utility model relates to a kind of wind detection sensor, especially can measure the wind-force of three-dimensional space vectors wind and the parallel sensor of wind direction simultaneously.
Background technology:
Wind vector is one of basic meteorological element, also is one of the most basic characteristic quantity of atmospheric boundary layer.Wind is owing to air flow produces, and is that pulsation by many small scales is superimposed upon the trivector on the large scale rule air-flow.On meteorology, often keep watch and consider as two-dimensional vector.It is determined by two parameters, i.e. wind speed (modulus of wind vector) and wind direction (argument of wind vector).The device that is used for measuring these two parameters is called as wind detection sensor, is mainly used in weather preparation and analysis of Wind Energy Resource, the addressing of wind field microcosmic, blower fan and the calculating of wind field generated energy etc.And in the meteorological observation field, the degree of accuracy of wind detection sensor can directly have influence on the accuracy of weather preparation; In the wind energy development field, the performance of wind detection sensor can have influence on directly that can the automatic control system of aerogenerator optimum pounces on and grasps wind resource and generate electricity.Therefore, along with the development of environmental science and the large-scale application of wind generating technology, research can anemometer widespread use, that degree of accuracy is high become current urgent problem.
According to surveying wind principle difference, the main type of anemometer has: (1) utilizes the heat dissipation type that concerns between the intensity of cooling of heating object and the speed air flow, mainly is to be used to measure little wind speed, but energy measurement wind direction not.(2) utilize sound wave in atmosphere velocity of propagation and the temperature of air and wind speed between the acoustics formula that concerns, the acoustics wind gage does not have rotatable parts, has working stability, not fragile, response is fast, can measure wind speed component along any assigned direction, but cost an arm and a leg, and long-term stability in use is poor.(3) utilize the aerodynamic rotary of airflow, comprise two kinds of vane formula and propeller types.Because bigger than other wind detection sensor measurement ranges, cost is lower, so what be most widely used at present is vane formula wind gage.But based on vane formula and wind wheel type, because runner is a moving element, factors such as mechanical friction, silt dust accretions make the reliability of instrument not high, and error is bigger, and long-term stability in use is relatively poor.And swinging of weathervane can not be aimed at wind direction accurately, can produce the side component, the reduction mean wind speed of meeting part.
Modern weather monitoring station multidirectional the development of whole day unmanned.Set up automatic weather monitoring station, press for the precision height, and the automatic monitor of stable performance under various environment-the comprise wind detection sensor that reaches this requirement.
Summary of the invention:
But in order to obtain the wind detection sensor of high reliability, high precision, long service life widespread use, the utility model provides a kind of parallel wind detection sensor, this sensor not only can be measured the wind-force and the wind direction of three-dimensional space vectors simultaneously, cost is low, simple in structure, can also be applied to various survey wind fields widely and close.
The technical solution of the utility model is as follows:
A kind of parallel-type three-dimensional wind detection sensor of the present utility model, it comprises parallel-connection type six-dimension force sensor device and sense wind apparatus,
Described parallel-connection type six-dimension force sensor device comprises as the Stewart platform of matrix and six resistance strain type pressure sensors, described matrix comprises upper and lower support platform and six elastic supporting bars that are connected upper and lower support platform, and pastes the resistance strain gage of described six resistance strain type pressure sensors on six elastic supporting bars respectively; Described sense wind apparatus is a spherical shell, and this spherical shell is connected on the upper support platform of Stewart platform.The size and Orientation of sense suffered wind-force on the wind apparatus be can record by six-dimension force sensor, the speed and the direction of air-out just can be resolved then by aerodynamic principle.
The utility model proposes and a kind ofly can measure the wind-force of three-dimensional space vectors and the parallel wind detection sensor of direction simultaneously, its sense wind apparatus is made spheroid, like this can according to aerodynamic principle calculate easily from the size of the wind-force of any direction with feel wind apparatus the relation between the stressed size; The parallel-connection type six-dimension force sensor device is a kind of sextuple power/torque sensor based on the Stewart platform, what install on six flexible members of the upper and lower platform of connection of Stewart platform is resistance strain type pressure sensor, the resistance strain type sensor key property is the accuracy height, non-linear and hysteresis error is little, creep is little, and comprehensive compensation has all been carried out in zero balance, zero temperature influence, the influence of sensitivity temperature and the output sensitivity standardization of sensor.
When the natural wind of any direction affacts on the sense wind apparatus in from three dimensions, can produce acting force thereon, the varying in size of wind, the size of acting force is also different.Just can measure suffered wind-force size and direction on the sense wind apparatus by the parallel-connection type six-dimension force sensor device that links to each other with the sense wind apparatus, when the parallel-connection type six-dimension force sensor device that its ultimate principle is based on the Stewart platform is subjected to feeling the wind force vector that passes on the wind apparatus, six elastic supporting bars on it produce elastic deformation, make and stick on its surperficial resistance strain gage (conversion element) also in company with producing distortion, after the resistance strain gage distortion, its resistance will change (increase or reduce), through corresponding metering circuit this resistance variations is converted to electric signal (voltage or electric current) again, thereby external force is transformed to electric signal, so can calculate the size and Orientation of wind-force by the Stewart parallel principle.Parallel-connection type six-dimension force sensor device output voltage signal is delivered to single-chip microcomputer after amplifier amplifies then, utilizes wind action power and respective relationships can calculate the size and Orientation of output wind speed again.
