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.
本发明提供了一种无人机冗余飞控模块的无扰切换方法和装置,该装置通过第一飞控模块和所述第二飞控模块相互发送预设频率的PWM波信号以监控对方的状态,当其中一个飞控模块发生故障则将另一个飞控模块设置为主控制模块,由于数据在第一飞控模块和第二飞控模块之间始终是双向传输的,因而在第一飞控模块在先发生故障再恢复主控制功能后,其也可以在第一时间接收第二飞控模块传输的飞行数据进行同步,从而实现了无人机飞行控制的无扰切换。
