Embodiment 1

[0039] Embodiment 1 of the present invention provides a UAV flight control system based on distributed redundancy bus, its structure is as follows figure 1 As shown, it includes: motion controller, three flight control computers (denoted as flight control computer Ⅰ, flight control computer Ⅱ, flight control computer Ⅲ), three GPS (denoted as GPSⅠ, GPSⅡ, GPSⅢ), three IMUs (denoted as IMUI, IMUII and IMUIII) and three barometric altimeters (denoted as barometric altimeter I, barometric altimeter II and barometric altimeter III).

[0040]Three GPSs, three IMUs and three barometric altimeters are respectively connected to the bus to encapsulate the collected data into data packets and transmit them to the bus; each flight control computer receives the data packets transmitted by the bus, and according to the data packets The device ID in the ID identifies which device the data packet comes from, compares the data of different devices with the same data type label, and votes accor...

Embodiment 2

[0060] Embodiment 2 of the present invention provides a UAV flight control method based on a distributed redundancy bus, which includes:

[0061] Step S101, the bus carries the data packets transmitted by each acquisition device; the transmitted data packets include: device ID, data type label, data content part and check digit; the data type part includes data collected from each GPS Satellite data, measurement data collected by each IMU or flight altitude of the drone measured by each barometric altimeter;

[0062] Step S102, each flight control computer receives in real time the data packet transmitted from each acquisition device carried on the bus; each flight control computer analyzes the data packet received at the current moment, and obtains the device ID, data type label, data content part and check digit;

[0063] Step S103, each flight control computer identifies the device source of the data packet according to the device ID in the data packet, compares the data w...

Abstract

The invention provides a UAV flight control system and flight control method based on a distributed redundancy bus, wherein each GPS, IMU and barometric altimeter are connected to the bus, and the measurement data are encapsulated into data packets in real time and transmitted to the bus. to the bus; each flight control computer receives the data packets transmitted by the acquisition equipment carried on the bus in real time; The data packet of the obtained flight parameters is transmitted to the rest of the flight control computer; the flight parameters calculated by itself are encapsulated into the data packet and transmitted to the actuation controller; the data packet includes: device ID identification, data type label, data content part and check digit. The present invention configures a plurality of flight control computers and acquisition devices to work in parallel through the distributed redundancy bus, so that the present invention has stronger fault tolerance and improves the reliability of unmanned aerial vehicle flight.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle flight control system and flight control method based on a distributed redundancy bus. Background technique [0002] Unmanned aerial vehicle (Unmanned Aerial Vehicle, referred to as UAV) is an unmanned aircraft controlled by radio remote control equipment and its own program control device. With the rapid development of drone technology, drones have been widely used in civil industries such as urban management, agriculture, geology, meteorology, electric power, emergency rescue, and video shooting. [0003] UAVs usually include motion controllers, flight control computers and acquisition equipment, such as IMU (Inertialmeasurement unit, inertial measurement unit), GPS, altitude measurement modules (such as barometer, ultrasonic ranging, radar ranging), etc. The IMU, GPS, and altitude measurement modules transmit the measurement data to the fligh...
