摘　　要： 本文介绍了一种8031两模冗余容错单片机系统,该系统采用脉冲级同步、总线采样比较检错和检查点恢复等技术,具有故障卷回恢复、诊断隔离、降级运行功能,从而较大地提高系统的可靠性。 This paper presents a duplex redundancy fault—tolerant system of 8031 single—chip microcomputsr (SCM), in which many kinds of techniques, including pulse synchronization, error detection with bus sampling comparison, and checkpoint recovery, etc. are applied. The system is of the functions of fault rollback recovery, diagnosis for isolation and degraded running. Therefore, its reliability has greatly been improved.
