Abstract

The invention is to provide a UAV (unmanned aerial vehicle) redundant system based on a CAN bus. The system comprises a CAN physical layer, a CAN protocol layer and a UAV control redundant backup. The CAN physical layer comprises a CAN bus interface; through the CAN bus interface adopted in a UAV control system, UAV inner wiring is reduced; the CAN protocol layer and the UAV control redundant backup are connected with the CAN bus interface; the CAN protocol layer is used for presetting flag bits of main / backup data in the UAV control redundant backup; and the UAV control redundant backup is used for determining the main / backup data as effective backup data based on the flag bits of the main / backup data and a preset redundant backup mechanism, thereby realizing redundant backup of the UAV control system, and improving reliability of the control system.

Description

technical field [0001] The present application relates to the field of unmanned aerial vehicles, in particular to a CAN bus-based redundant system for unmanned aerial vehicles. Background technique [0002] UAVs have a wide range of applications in disaster prevention and rescue, scientific investigation, wind power inspection, industrial environmental protection and other fields, and the flight control system of UAVs is an important part of UAVs. and practicality play an important role. Especially in industrial drones, the manufacturing cost of industrial drones is high, especially for fixed-wing drones, such as expensive carbon fiber materials for the fuselage; Before users, they will go through a large number of long-term flight tests to improve the reliability of industrial drones and facilitate the promotion and application of industrial drones. [0003] In the existing technology, it is very necessary to ensure and improve the reliability of industrial drones in al...
