摘要： 在分析C/OS-II系统的基础上增加多MCU容错实时操作功能，可以对当前任务运行状态实时进行一致性操作，使多MCU中的一个节点在出现死节而崩溃时，其他节点可以实现死节的决策，并恢复其坏死节点的任务状态使其继续运行。通过三MCU方式结构及运行验证，改进的系统表现出稳定可靠的容错能力。

Abstract: The paper analyzes C/OS-II system, and adds some fault-tolerant operating modules based on multi-MCU modules. The modules achieve the coherent real-time operation for the current state of the running tasks. If one of the multi-MCU modules breakdowns, other MCU modules can judge the fault and resume bad system state to run on decision-making. The fault-tolerant real-time operating system, which shows a stable dependable fault-tolerant ability, has been tested on three MCUs.
