Unmanned aerial vehicle engine control device and method

Abstract

The embodiment of the invention provides an unmanned aerial vehicle engine control device and method. The device comprises: a detection mechanism, a servo mechanism and a control mechanism; the detection mechanism is arranged on an engine, the detection mechanism and the servo mechanism are connected with the control mechanism, and the servo mechanism is connected with a choke valve of a carburetor of the engine; the detection mechanism is used for detecting the working state of the engine and sending the working state information of the engine to the control mechanism; the control mechanism is used for judging whether the engine stalls halfway or not according to the working state information, and sending a choke valve closing instruction to the servo mechanism if the engine stalls halfway; and the servo mechanism is used for driving the choke valve to close according to the choke valve closing instruction so as to restart the engine. The unmanned aerial vehicle engine control deviceand method solve the technical problems that the engine cannot be automatically restarted, the operation is inconvenient and the working efficiency of equipment for supplying power by using the engineis reduced in the prior art.

Description

technical field [0001] The present application relates to the technical field of engine control, in particular, to an engine control device and method for an unmanned aerial vehicle. Background technique [0002] As the power supply unit of various equipment, the engine plays a vital role in the development of science and technology. Piston engines are commonly used in small and medium drones. At present, most piston engines use carburetors to supply oil, and all carburetors include a choke structure, which is mainly used to assist the engine to start normally. If there is no oil in the engine cylinder or the oil circuit is not full of fuel, the choke valve needs to be closed manually before the engine starts, so that the negative pressure generated in the casing can effectively suck the fuel in the oil circuit when the engine is running, and the choke valve needs to be opened during normal operation. The damper ensures that sufficient air can be sucked into the cylinder a...

AI Technical Summary

Problems solved by technology

However, when the engine is running, it often stalls

During the flight of the UAV, if the choke door is manually controlled, the UAV needs to be landed, which will affect the normal operation of the UAV.

In addition, for the engine installed in a narrow space, it is difficult to manually control the choke valve

That is, there are technical problems in the prior art that the engine cannot be automatically restarted, the operation is inconvenient, and the working efficiency of the equipment powered by the engine is reduced.
