Problems solved by technology

[0005] However, the inventor found that the main flight controller will only synchronize the flight data when it is in a normal working state. Any flight data, resulting in the inability to effectively monitor the status of the UAV when it restores the main control function, there are certain security risks

Abstract

The invention provides an undisturbed switching method and device for redundant flight control modules of an unmanned aerial vehicle, and the device comprises the steps: enabling a first flight control module and a second flight control module to transmit PWM wave signals with a preset frequency to each other so as to monitor the states of each other, and enabling the other flight control module to be set as a main control module when one flight control module breaks down, since the data is always bidirectionally transmitted between the first flight control module and the second flight control module, the first flight control module can receive the flight data transmitted by the second flight control module at the first time for synchronization after the first flight control module breaks down and then recovers the main control function, thereby realizing the undisturbed switching of the flight control of the unmanned aerial vehicle.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicle flight control, in particular to a disturbance-free switching method and device of a redundant flight control module of an unmanned aerial vehicle. Background technique [0002] Unmanned aerial vehicle, referred to as "UAV", is an unmanned aerial vehicle controlled by radio remote control equipment or its own program control device. With the development of science and technology, UAV technology is becoming more and more mature. UAVs are widely used due to their fast speed, flexible operation, wide application, low cost, and good maneuverability. They not only play an extremely important role in modern warfare. , and has a broader prospect in the civilian field. [0003] The UAV flight control module is the core of the UAV. For UAVs using a single flight control module, if the flight control module is abnormal or faulty during the flight, it will directly cause the UAV flight control to appe...
