Technical Field
The utility model relates to a meteorological instrument device field especially relates to a dedicated anemometry device of unmanned aerial vehicle.
Background
With the rapid development of unmanned aerial vehicles, it becomes possible to integrate various meteorological instruments into the unmanned aerial vehicle for observation. In meteorological observation, measurement of a wind direction in real time is very important for analysis of a result. The existing wind direction measuring devices are all based on land platforms and are composed of a section of rotatable measuring device. However, on the unmanned aerial vehicle platform, when the mode of hovering, based on the setting of hovering at the fixed point, the problem of spin appears in the unmanned aerial vehicle, therefore current anemometry device can't directly use on the unmanned aerial vehicle platform.
Because the observation to the wind direction is the important component that unmanned aerial vehicle air pollution detected, the source of air contaminant, especially high-altitude wind direction information can be judged in the survey of wind direction, has the guide effect to the result of air quality detection. To achieve this, it is necessary to do so with a wind direction transducer. But because unmanned aerial vehicle, especially many rotor unmanned aerial vehicle do not have clear and definite directionality in the work, so ordinary wind direction changer can't the direct mount use on unmanned aerial vehicle. Therefore, it is very meaningful to design a dedicated wind direction detection device of unmanned aerial vehicle, and this design is emphatically to the transformation of traditional wind direction changer and the measurement research of accurate wind direction.
SUMMERY OF THE UTILITY MODEL

Detailed Description
The following combines the attached drawing to be right the utility model provides a specific implementation of dedicated anemometry device of unmanned aerial vehicle does the detailed description.
The specific block diagram of the utility model is shown in fig. 1, wherein the data acquisition circuit mainly comprises an electronic compass three-axis magnetic field sensor QML5883L, a single chip microcomputer MSP430F149 and a voltage type wind direction transmitter YJ-FX 100. The MSP430 series single-chip microcomputer is mainly characterized by low power consumption, 3.3v low voltage of a power supply, 0.1uA of power consumption current under a RAM data holding mode, 250uA/MIPS (million instructions per second) of power consumption in an active mode, and 50nA of maximum leakage current of an I/O input port, so that the MSP430 series single-chip microcomputer is very suitable for being applied to a monitoring system of an unmanned aerial vehicle platform. In addition, considering that the F149 model has a hardware multiplier, the hardware multiplier has higher response speed in practical application; the 12-bit A/D converter arranged in the single chip ensures that the resolution and the precision of the result meet the design requirements.
The wind direction sensor adopted by the system is a YJ-FX100 voltage type wind direction sensor. The range is-180 degrees, the working temperature range is-20-80 degrees, and the output voltage is 0-5V. Experiments verify that the sensor has good linearity and repeatability, the resolution can reach within 0.1 degree, and the design requirement can be met. When the system starts, the vane of the wind direction sensor rotates to the current wind direction, the output voltage of the sensor correspondingly changes, the output voltage value is subjected to AD conversion through the single chip microcomputer MSP430F149, and the current angle of the wind direction sensor is recorded. And finally, the single chip microcomputer carries out angle compensation by using the angle data of the electronic compass to obtain the final wind direction angle.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
