Height measurement device and method based on unmanned aerial vehicle

Abstract

The invention relates to a height measurement device and method based on an unmanned aerial vehicle. The device comprises a first processor, an ultrasonic ranging module, a voice alarm module and a voltage-stabilized power supply module, wherein the ultrasonic ranging module, the voice alarm module and the voltage-stabilized power supply module are electrically connected with the first processor.Through the height measurement device comprising the first processor, the ultrasonic ranging module, the voice alarm module and the voltage-stabilized power supply module, the structure is simple, themeasured distance is far, and operation is stable; moreover, since the ultrasonic technology is utilized to detect a height distance, the device has the characteristics that frequency is high, wavelength is short, the diffraction phenomenon is small, and particularly the directionality is good and rays can be formed and propagated in a fixed direction; and through the method, flight height can bedetected in real time during flight of the unmanned aerial vehicle, a voice alarm can be given when the flight height of the unmanned aerial vehicle is excessively high or excessively low or the height change rate is abnormal, and therefore the flight safety of the unmanned aerial vehicle is effectively guaranteed.
