【摘要】 本文第一部分介绍一种热连轧过程控制计算机系统的特点。该系统由两级递阶计算机网组成,含有约300个闭环控制回路,控制着由加热区到卷取区整条生产线。我们介绍它的系统网络结构、精轧控制算法和过程控制软件系统。本文第二部分对塔形网络结构和分散处理计算机网,就下列问题进行了讨论和比较。例如,控制方法的安排,系统结构、系统可靠性、响应速度和某些控制算法。我们认为:上述系统虽然有许多优点,但在我们今后的设计中仍有若干需改进之处。更多还原

【Abstract】 In the first part of this paper, some features of the process control com-puter system of a hot mill plant are introduced. The system has been set upa two- level hierarchical computer network, which manipulates about 300closed control loops and controls whole process from the reheating zone tothe coiling zone. Some reviews on system architecture, finishing roll controlalgorithms and process control softwares are presented. In the second part,some outlooks on the pyramid type of network system as concerns the arran-gement of control means, the systsm architectures and its reliabilities, theresponse speed and the control algorithms are paid in comparison with thedistributed computer network. An attempt has been made to indicate that,although there exist more outstanding merits on the system as stated above,it is still necessary to give the development in our future design.更多还原
