Embodiment 1

[0020] This embodiment provides a redundant control method for an aircraft, which is applicable to an aircraft with two CAN buses, wherein one CAN bus constitutes a redundant communication circuit for multiple flight control processors, and the other CAN bus constitutes a plurality of The control communication loop between the flight control processor and the mounted device.

[0021] figure 1 The flow chart of the redundant control method of the aircraft provided by the embodiment of the present invention is figure 1 As shown, the method includes:

[0022] S100, during the initialization process of the aircraft, determine a main flight control processor from the multiple flight control processors of the aircraft, determine other flight control processors as backup flight control processors, and determine the control priority of the backup flight control processors right.

[0023] During the initialization process of the aircraft, one of the multiple flight control processor...

Embodiment 2

[0047] In order to describe the redundant control process of the aircraft in the present invention in more detail, the present invention is described in detail through Embodiment 2.

[0048] figure 2 The communication line block diagram of the aircraft provided for the embodiment of the present invention, such as figure 2 As shown, the aircraft includes two CAN buses, one of which constitutes a redundant communication circuit for multiple flight control processors, and the other CAN bus constitutes a control communication circuit between multiple flight control processors and mounted devices.

[0049] In this embodiment, the structure of each flight control processor is the same. In practical applications, the flight control chip (such as the control chip whose model is STM32F756) of the ARM embedded platform and the sensor module can be used to jointly form the flight control processor. The number of control processors is more than two, preferably three. In practical appli...

Abstract

The invention discloses a redundancy control method of an aircraft. The method comprises steps as follows: in an aircraft initialization process, a main flight control processor is determined from multiple flight control processors of the aircraft, other flight control processors are determined as spare flight control processors, and the control priority of the spare flight control processors is determined; the main flight control processor controls a mounted device of the aircraft through a control communication loop and judges whether the main flight control processor fails in real time, if failure occurs, control failure information of the main flight control processor is broadcasted to each spare flight control processor through a redundancy communication loop, and the spare flight control processor at the highest priority level is controlled to serve as a new main flight control processor to continuously control the aircraft. By means of the technical scheme, redundancy of the whole flight control process can be guaranteed, and safety guarantee of the aircraft is improved.

Description

technical field [0001] The invention relates to the field of aircraft control, in particular to a redundant control method for an aircraft. Background technique [0002] UAVs are now widely used for aerial photography in the consumer market, as well as disaster relief support, power inspection, scientific surveying and mapping, and plant protection in the professional market. At present, most UAV systems mainly use the traditional serial port communication method between the various component subsystems, that is, the flight control system is the center, and the gimbal system and the Electronic Speed ​​Control (ESC) power system (Electronic Speed ​​Control, ESC) are connected through the serial port. etc.; but the serial port communication method has defects in the system-wide anti-jamming, multi-redundancy, scalable and reliable security requirements, and has serious security risks. [0003] With the passage of time, UAV system solutions based on the Controller Area Network...
