摘　　要：本文论述 STD 总线双机容错系统的设计与实现,该系统为工矿企业提供高可靠性的处理机模块。本系统采用双机容错原理,模块内部包含两个CPU 协同工作,还可用同样的处理机模块作为热备份,当运行模块失效后系统能自动切换到备份模块运行,实现系统的不间断运行。文中最后讨论了系统的软硬件结构及主要实验结果。This design and implementation of a double modular.fault-tolerant computer sys-tem interfacing to STD-BUS is presented for the industrial process oriented processor withhigh reliability.There are two CPUS which cooperate in a processor module and the sameprocessor module as the warm spare module in the system.When active module failed,thespare is switched on,thus making the system uninterrupted running.Finally,the paper dis-cussed the hardware and the software structures of the system and its main experimental re-sults.
