Unmanned aerial vehicle flight control system based on controller area network (CAN) bus

Abstract

The invention discloses an unmanned aerial vehicle flight control system based on a controller area network (CAN) bus. The unmanned aerial vehicle flight control system comprises a master control chip, a conversion control chip and a sensor unit, wherein the sensor unit comprises an attitude sensor, a magnetic sensor, an atmospheric pressure altimeter, a temperature sensor, a rotary speed sensor and a global positioning system (GPS) receiving module, which are respectively used for acquiring information about attitude, magnetic course, height, cylinder temperature and exhaust temperature, rotary speed, and position and speed; the conversion control chip converts the input rotary speed information of an unmanned aerial vehicle engine and the cylinder temperature and exhaust temperature of the unmanned aerial vehicle engine, and then transmits the converted information to the master control chip through the CAN bus; and the master control chip operates unmanned aerial vehicle flight control according to the information which is acquired by the sensor unit, and the conversion control chip outputs a steering engine control signal according to control policy information which is output by the master control chip. The unmanned aerial vehicle flight control system provided by the invention has the characteristics of high anti-interference capacity and high expansion capability, and is high in generality.

Description

technical field [0001] The invention belongs to the field of automatic control, in particular to a CAN bus-based drone flight control system. Background technique [0002] UAVs are widely used in disaster prevention and rescue, scientific investigation and other fields, and the flight control system is an important part of UAVs, which plays an important role in the intelligentization and practicalization of UAVs. The existing UAV flight control system has the problems of poor anti-interference ability and scalability, which has become a bottleneck restricting the development of UAV flight control system. Contents of the invention [0003] Aiming at the shortcomings of the traditional UAV flight control system, a UAV flight control system based on CAN bus with strong anti-interference ability and good scalability is provided. The UAV flight control system can be used for fixed-wing unmanned aerial vehicles Flight controls for drones and unmanned helicopters. [0004] The ...
