攀钢1450热连轧改造系统过程计算机之间的通讯

Communication Among the Process Computers of Pangang1450 Hot Strip Mill Transformation System

简单介绍了攀钢1450热连轧改造系统过程计算机之间相互通讯的三种方式。描述了系统中数据中心、各过程控制计算机的功能,并详细说明了加热炉、粗轧、精轧过程计算机之间以及过程计算机与数据中心之间的通讯接口,在通讯程序中运用了自动重发,重连等机制,保证了通讯的快速性、正确性和可靠性。实践表明,通讯系统运行平稳可靠。

Three communication methods between computers of the hot strip mill system are introduced simply. Data center of this system and functions for each process control computer are described. The communication interfaces among the process computers of heating fumaere, rough mill and finishing mill as well as the interface between the process computer and data center are also specified. The practice shows that the communication system is running stably and rehably.
