摘　　要：由于飞行器控制系统中需要共享的数据量急剧增加且系统控制周期越来越快,导致数据传输总线的网络负载率越来越高,系统的实时性和可靠性受到影响而变差.为此,综合总线任务调度算法、冗余设计方法和网络管理策略,提出一种多功能双CAN网络混合调度策略.实验结果表明:该策略不但可以实现数据传输通道的冗余备份功能,提高了系统的可靠性,而且还保证了关键指令信息传输的实时性和非实时状态信息传输的公平性.Due to the data quantity increasing dramatically and the system control cycle becoming more and more fast,the busload of aircraft data transmission network becomes higher and higher. The real time and reliability of aircraft control system becomes worse. To solve this problem, colligated from bus task scheduling algorithm, system redundancy design method and network management strategy, a multifunctional dual CAN network mixed scheduling strategy is presented in this paper. The results show. This strategy, not only realizes redundant backup of the data transmission channel to improve the system reliability, but also ensures real time of the key command information massages and fairness of the state information massages.
