Fault-tolerant and the Development of Instrumentation

对容错技术与仪表的发展进行了探讨。首先 ,从工业生产过程的安全经济运行与控制需要出发 ,介绍了过程控制中容错的基本思想。针对过程控制和现场总线技术的发展进程 ,尝试提出了容错仪表控制装置的概念及现代仪表技术发展中应遵循的若干原则。

In this paper, the fault-tolerant in process control and the instrument development are approached. Firstly, the fault-tolerant process control is introduced according to the safety and economics requirement of chemical, power, iron and steel processes. Based on the state of the art of present process control and field bus instrument & control systems, the concept of fault-tolerant instrument, and some research essentials for process control and instrumentation are proposed.
