Abstract
Considering the requirements of internal communication capability of a flight control computer of a sample unmanned aerial vehicle (UAV), we propose a four-channel FlexRay bus redundancy management scheme, which focuses on the aspects of hardware redundancy, fault detection, logic switching, and system recovery.According to the communication and redundancy management mechanism on the designed FlexRay, real-time and reliable communication between functional units is realized, and the time to deal with communication error is less than 30 ms.Test results verify the correctness and practicality of the design in accordance with design specifications, and the design can meet the internal communication requirements of unmanned flight control computers.关键词
