Embodiment Construction

[0043] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0044] Such as figure 1Shown: a drone-based altitude measurement device, including a first processor, an ultrasonic ranging module electrically connected to the first processor, a voice alarm module, and a stabilized power supply module.

[0045] In a practical application scenario, the stabilized power supply module supplies power to the UAV height measurement device, and the first processor in the UAV height measurement device starts the ultrasonic ranging module after obtaining the working voltage.

[0046] The ultrasonic ranging module obtains the height information of the drone, and sends the height information to the first processor.

[0047] The first processor judges whether the altitude information exceeds...

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.

Description

technical field [0001] The invention relates to the field of distance measurement of unmanned aerial vehicles, in particular to an altitude measurement device and method based on an unmanned aerial vehicle. Background technique [0002] It is very important for UAVs to feed back flight altitude information in real time during flight. At present, the height measurement devices installed on UAVs often have complex structures, limited ranging distances, and unstable work. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides an altitude measurement device based on an unmanned aerial vehicle. [0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a height measuring device based on an unmanned aerial vehicle, comprising a first processor, an ultrasonic ranging module electrically connected to the first processor, a voice alarm module, a stable voltage su...
