Flight control method and system based on three-IMU redundancy technology

Abstract

The invention discloses a flight control method and system based on a three-IMU redundancy technology. The flight control system comprises a self-detection CPU, a three-IMU redundancy unit, a triple-redundancy voting output unit and a flight action control unit, wherein the self-detection CPU performs real-time receiving on data transmitted by the three-IMU redundancy unit in real time and performs parsing on a received data packet, the triple-redundancy voting output unit receives the data processed by the self-detection CPU and flight parameters and performs voting, and the flight action control unit receives the flight parameters transmitted by the triple-redundancy voting output unit, converts the flight parameters into electrical signals and then executes actions. In this way, the phenomenon that an unmanned aerial vehicle is out of control due to a fault of the flight control system is effectively avoided or reduced, the flight safety of the unmanned aerial vehicle is effectivelyguaranteed, the defects of poor stability and the like of conventional flight control are overcome, and the problem about emergency backup of the flight control system of the unmanned aerial vehicleis solved.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a flight control method and system with triple-IMU redundancy technology. Background technique [0002] Unmanned aircraft, referred to as "UAV", is an unmanned aircraft that is controlled by radio remote control equipment and its own program control device, or is completely or intermittently operated autonomously by an on-board computer. At present, with the development of science and technology, drone technology is becoming more and more mature, and drones are widely used due to their fast speed and flexible operation. From a certain point of view, UAVs can complete complex air flight tasks and various load tasks under unmanned conditions, and can be regarded as "air robots". [0003] UAV flight control refers to the control system that can stabilize the flight attitude of the UAV and control the autonomous or semi-autonomous flight of the UAV. It is the brain of the UAV...
