摘要

介绍了一种基于改进的分布式恢复块(DRB)的分布式过程控制容错系统。系统中的容错条款通过使用DRB覆盖软件故障;通过复制和DRB实现硬件故障;系统软件故障通过复制、松耦合、周期性状态消息和重新启动能力;通过复制和多种互连路径实现网络故障。可维护性通过驻留在系统管理器节点上的自动重启功能和日志功能得到增强。该系统被称为扩展分布式采油区块(EDRB)，已被实施并集成到化学处理系统中

A distributed fault tolerant architecture for nuclear reactor and other critical process control applications

A distributed fault tolerant system for process control that is based on an enhancement of the distributed recovery block (DRB) is described. Fault tolerance provisions in the system cover software faults by use of the DRB; hardware faults by means of replication and the DRB; system software faults by means of replication, loose coupling, periodic status messages, and a restart capability; and network faults by means of replication and diverse interconnection paths. Maintainability is enhanced through an automated restart capability and logging function resident on a system supervisor node. The system, called the extended distributed recovery block, or EDRB, has been implemented and integrated into a chemical processing system.<>
