摘　　要：现代无人机对飞行控制计算机的性能与安全性要求越来越高,使得基于CAN总线技术的一类飞行控制计算机内部总线负载情况越来越严重,因此有必要研究一种高数据传输率和高安全性的总线FlexRay代替CAN。基于CAN总线的分布式飞行控制计算机的网络结构和内部通信机制,设计了基于FlexRay网络的飞行控制计算机总线通信系统,并进行了通信测试验证,结果验证了FlexRay相对CAN在实时性、通信速率和效率上的优越性,为日后在新型飞行控制计算机上用FlexRay总线替代CAN总线打下了坚实的理论基础。The modern uninhabited aerial vehicle（UAV） increases the pertormance ana secunty reqmrements of the flight control computer, makes internal bus heavy load of flight control computer based on CAN bus more and more severe. It is necessary to study high data transfer rate and high security bus - FlexRay instead of CAN. Based on the network structure and internal communication mechanism of the uninhabited aerial vehicle （UAV） flight control computer and CAN bus, it designs the flight control computer communication system based on FlexRay Bus, and develops the internal communication software. Actual test proves that FlexRay Bus has great advantages over CAN bus in real time, communication speed and efficiency. This provides a solid foundation to using FlexRay instead of CAN in the new distributed UAV flight control computer.
