一、前言可靠性是人们共同追求的目标。本文试从一米七冷连轧机计算机控制系统结构出发,根据该系统十年的运行状况,运用数学模型的方法分析该系统的可靠性。可靠性并不是什么新概念,事实上人们天天都和可靠性打交道。系统的可靠性是在给定的时间内,在一定的环境下能够正常运行的概率。可靠性如何测量或分析呢?下面将用冷连轧机计算机控制系统的例子,采用较为系统的方法,对其可靠性作一初步探讨。二、计算机控制系统图武钢一米七冷连轧机计算机控制系统是由西德AEG公司设计研制的三级分散型计
First, the preface Reliability is the common pursuit of people’s goals. Based on the structure of the computer control system of one meter seven cold tandem rolling mill, this paper analyzes the reliability of the system according to the operating conditions of the ten years of the system and the mathematical model. Reliability is not a new concept, in fact, people are dealing with reliability every day. The reliability of a system is the probability that it will be able to operate normally in a given environment for a given period of time. Reliability how to measure or analyze? The following will be cold tandem mill computer control system example, a more systematic approach to its reliability for a preliminary study. Second, the computer control system diagram Wuhan Iron and the seven meters continuous cold rolling mill computer control system is designed by the West Germany AEG three decentralized meter
