Electronic speed regulator over-temperature protecting method, adjusting method, device thereof and unmanned aerial vehicle

Abstract

An embodiment of the invention provides an electronic speed regulator over-temperature protecting method, an adjusting method, a device thereof and an unmanned aerial vehicle. The over-temperature protecting method comprises the steps of acquiring the temperature of the electronic speed regulator; when the temperature is between a first temperature threshold and a second temperature threshold, regulating the highest output rotating speed of the electronic speed regulator for limiting the current rotating speed so that the current rotating speed does not exceed the highest output rotating speed; regulating the output rotating speed of the electronic speed regulator according to the highest output rotating speed. and when the temperature is higher than a second temperature threshold, stopping output of the electronic speed regulator, thereby stopping operation of the motor. Through the electronic speed regulator over-temperature protecting method, the adjusting method, the device thereofand the unmanned aerial vehicle, the highest output rotating speed of the electronic speed can be stepwisely reduced; and for maintaining balance of the unmanned aerial vehicle, the output rotating speeds of other electronic speed regulators are simultaneously regulated, thereby realizing slow landing of the unmanned aerial vehicle, and preventing an explosion accident caused by stopping output on the condition of an overhigh temperature; and furthermore when the temperature is higher than the second temperature threshold, outputting of the electronic speed regulator is controlled for stopping operation of the motor, thereby protecting the electronic speed regulator from damage caused by the overhigh temperature.

AI Technical Summary

Problems solved by technology

The electronic governor is composed of resistors, capacitors, MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistor, Metal-Oxide-Semiconductor Field-Effect Transistor), and other devices. In the application, the heat dissipation parts of the electronic governor need to be exposed, and are easily covered by the liquid dust, which is prone to poor heat dissipation

[0004] When the temperature of the electronic governor exceeds the limit value, most of the electronic governors used in drones do not have over-temperature protection or disconnect the output after the temperature exceeds the limit value, which causes the electronic governor to have poor heat dissipation temperature. When the temperature rises, the performance of the electronic governor will decrease, be damaged, or even burn out and cause a fire, or the output will be disconnected after the temperature exceeds the limit, resulting in the loss of power of the UAV and a bombing accident
