摘要
可靠的控制系统对于确保生产过程能连续、安全、经济地运行十分重要。系统的排错设计和容错设计是提高控制系统可靠性的有效手段。通过对控制系统和冗余、容错技术的分析,重点从控制系统的硬件和软件两个方面,介绍了利用容错技术提高控制系统可靠性的措施和方法。
The reliable control systems play an important role for production.The error-eliminate design and the error-tolerate design are the effective measures for enhancing the reliability of process control systems.The redundancy and the fault-tolerant technology of process control systems have been analyzed in this paper.The measure of enhancing the reliability is introduced in hardware and software two sides emphases.
