【摘要】 容错、可靠性和分布式体系结构在工业控制系统中是非常重要的应用技术.本文讨论了文献存在的不同容错体系结构.在具有分布式系统体系结构的工业控制系统基础上,建立了三冗余同构的CAN现场总线控制系统,研究了它的组合系统可靠性.描述了该系统具有故障时,系统重构部件的组合使用优先权队列.分析表明三冗余结构现场总线控制器可大大提高控制系统的可靠性和容错能力.更多还原

【Abstract】 The fault-tolerance,reliability and distributed architecture are the most important technology in in- dustrial control systems.The redundant system with the three same units is built for CAN fieldbus control sys- tem based on the distributed architecture of industrial control application.The paper represents the method of combinational application of the components in according to the priority sequence of system reliability when the fault of system occurs.The analysis indicates that the redundant controller with the three same units improves the more reliability and fault-tolerant ability of control systems.The redundant system with the three same units is built for CAN fieldbus control.更多还原
