An automatic test device for the kinetic energy efficiency of the UAV arm

Abstract

The invention discloses an unmanned-aerial-vehicle-arm kinetic efficiency automation test device. The device comprises a test platform and a test terminal. The test platform and the test terminal carry out data interaction through wireless communication. The test platform is used for bearing a unmanned aerial vehicle arm to be tested and possesses a power supply interface used for connecting the unmanned aerial vehicle arm to be tested and a signal interface. The test platform is also used for adjusting a control signal pulse width of the unmanned aerial vehicle arm to be tested according to a control signal sent by the test terminal so as to adjust a rotating speed and power of the unmanned aerial vehicle arm to be tested, and is used for collecting a voltage, a current and a thrust parameter generated by a propeller during a unmanned aerial vehicle arm operation process. The test terminal is used for receiving the voltage, the current and the thrust parameter collected by the test platform, carrying out mean value filtering on the received voltage, the current and the thrust parameter and calculating and acquiring arm kinetic efficiency. The device can automatically measure the arm kinetic efficiency according to a preset program so that automation of kinetic efficiency test work is realized.

Description

technical field [0001] The invention belongs to the technical field of multi-rotor UAVs, and more specifically relates to an automatic test device for the kinetic energy efficiency of the UAV arm. Background technique [0002] During the production process of the UAV, it is necessary to ensure the consistency of the dynamic performance of each arm. Therefore, it is necessary to test the dynamic performance of each arm before assembling the whole UAV; among them, kinetic energy efficiency is the most important performance indicator. To measure the kinetic energy efficiency of a machine arm, it is first necessary to measure the power consumption of the whole machine arm and the thrust generated by the machine arm under the state of power consumption; according to the power consumption and thrust, the unit power consumed by the machine arm can be obtained The lift force that can be provided; the lift force corresponding to each power point of the arm can be measured, and the ki...

Problems solved by technology

[0003] In the existing drone industry, most of the tests on the kinetic energy efficiency of drone arms are self-developed and used by manufacturers. Usually, various finished instruments (such as voltmeter, ammeter, electronic scale, etc.) are assembled together, and manually Adjust the knob to change the pulse width value of the control signal, thereby changing the working state point of the machine arm, and record the current and thrust values ​​corresponding to each working state point in turn, and the efficiency is low; more importantly, when testing the kinetic energy efficiency of the drone arm, The arm of the UAV to be tested is in a state of high-speed rotation; and the testers need to adjust and read data at a position close to the test equipment, which poses a great safety hazard to the testers, and there is a risk of being hit by a high-speed rotating propeller risk of injury
