Embodiment 1

[0051] Turn on the switch module before the UAV is about to take off, and the autopilot sends a start signal after receiving the start command sent by the ground station; figure 2 , the start signal is input from pin 1 of the button switch KN6A-202F, and the output is transmitted from pin 2 to the control module. The control module selects STM32F103C8T6, the start signal is input from pin 17, and the control module judges whether it is continuously received within 2s Two start signals, if received, the start signal will be output from pin 30. There are two sets of MOS tubes in the drive motor. The drive motor receives the start signal and enables to open the two sets of MOS tubes, so that the drive motor is connected to the start power supply. The drive motor then drives the engine through the reducer to start.

Embodiment 2

[0053] There is a Hall speed sensor in the autopilot. Turn on the switch module before the drone takes off. The preset start signal triggers the command in the autopilot. When the trigger condition is met, that is, when the Hall speed sensor detects that the transmitter speed is less than 100RPM, The autopilot sends a start signal through the signal line; figure 2 , the start signal is input from pin 1 of the button switch KN6A-202F, and output from pin 2 to the control module; for example image 3 , the control module selects STM32F103C8T6, the start signal is input from U7 pin 17, and the control module judges whether the start signal is received three times continuously within 3s, and if received, the start signal is output from pin 30. like Figure 4 , the start signal is sent to the optocoupler isolation module N1 pin 2, when there is no start signal input, IO is high level, the internal diode of N1 is not conducted, the signal is cut off, and the engine does not work; ...

Abstract

The invention belongs to the UAV control system and its control method, which solves the problems of the unintentional touch of the airborne starter in the prior art, which may lead to false start, and the problem of self-start due to misjudgment, and further provides an automatic UAV. The starting system and its control method. The self-starting system includes a starting power supply, a switch module connected in sequence, a control module, a drive motor, a reducer and an engine; the specific control method is to turn on the switch module before the drone takes off; the autopilot sends a start signal through the signal line, and the switch module Transmission to the control module; if the control module receives multiple startup signals continuously within the preset time, the drive motor will be started, otherwise it will not be started; if the drive motor is judged to be started by step 2, the control module will control the drive motor to start, and the drive motor will pass The reducer starts the engine. It effectively avoids the problems of self-start caused by false start and misjudgment, and further improves the safety of the drone.

Description

technical field [0001] The invention belongs to an unmanned aerial vehicle control system and a control method, in particular to an unmanned aerial vehicle self-starting system and a control method thereof. Background technique [0002] At present, with the intelligent and modular evolution of drones, the functional complexity and fineness of drones are getting higher and higher. UAVs are widely used by all walks of life due to their high precision, long distance and remote control. With the favor of the industry, various drones have emerged as the times require. In the UAV and aircraft model industry, due to the low load capacity of the UAV, considering the weight of the whole machine, most UAVs are not equipped with an engine self-starting device. Before the drone takes off, the operator holds the starter and starts the engine before taking off. However, during the actual mission flight, due to environmental factors such as temperature, humidity, and altitude, the engine ...
