一种柔性容错TTCAN协议调度算法的设计与应用

摘要

CAN bus has been widely used in the current weapons and equipment. Since it uses priority-based non-destructive bitwise arbitration mechanism,there are some flaws of real-time and reliability in the communication. In response to these problems,this paper introduces a time-triggered TTCAN protocol. After the analysis of the popular scheduling algorithm of TTCAN protocol,we put forward a four-point program to optimize the algorithm and design a new fault-tolerant scheduling algorithm,and finally we have an example of a certain type of tanks for the application background to verify it.%CAN总线在当前的武器信息装备中已经得到广泛的应用，其采用的基于优先级的非破坏性逐位仲裁机制，在通信实时性和可靠性等方面存在一定缺陷。针对上述问题，引入了基于时间触发的TTCAN协议，在分析当前流行的TTCAN协议调度算法的基础上提出了4点优化方案，设计出一种新型容错调度算法，并以某型坦克为应用背景进行了实例验证。
