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...

Embodiment

[0049] see figure 1 , figure 1 It shows a UAV engine control device 100 provided by the embodiment of the present application. The UAV engine control device 100 includes: a detection mechanism 110 , a servo mechanism 120 , and a control mechanism 130 . The detection mechanism 110 is arranged on the engine, the detection mechanism 110 and the servo mechanism 120 are connected with the control mechanism 130, and the servo mechanism 120 is connected with the choke valve 150 of the carburetor 160 of the engine. The detection mechanism 110 is used to detect the working state of the engine, and send the information on the working state of the engine to the control mechanism 130 . The control mechanism 130 is used to judge whether the engine is turned off midway according to the working state information, and if the engine is turned off halfway, send a door closing command to the servo mechanism 120 . The servo mechanism 120 is used to drive the choke valve 150 to close according t...
