| Abstract: | A method for improving the reliability of the STD industrial microcomputer is proposed, which consists in two STD microcomputefrs working on-line (hot-redundancy). In an industrial control system, a dual system (hot-redundancy) is better than a duplex system (cold redundancy)as there exist no such problems as switch-over and data abandonment. A comparison-arbitrator unit for the dual STD microcomputer, system (DSMS) and fault-tolerant software for generating correct data output have been developed. The fault-tolerant techniques adopted for hardware and software in the system are discussed in detail. |
