唐钢冷连轧机过程控制系统

为提高唐钢新建5机架冷连轧机组的自动化控制水平并保证产品控制精度,设计开发了过程控制系统.系统平台采用通用PC服务器和Windows 2000操作系统.过程控制系统设计为数据库、人机界面和核心控制系统三部分.数据库系统采用Oracle数据库,存储运行过程中需要保存和交换的大量数据.使用VB开发人机界面,实现人机交互功能.核心控制系统基于VAIronment软件开发环境,采用C++编程,实现系统管理、数据通讯、运行信息管理、标签信息管理、过程跟踪等辅助功能,并通过模型计算实现核心的设定计算功能.现场应用表明,该系统具有非常高的设定精度.

Process Control System for Tandem Cold Mill in Tangsteel

With the purpose of upgrading automation control level,a process control system has been developed for the new five-stand tandem cold mill in Tangsteel,using the PC server and Windows 2000 operation system as the system platform.Database,human-machine interface(HMI) and core control system are all included in the design of the process control system,where the Oracle database is used to store all the data needed to save or exchange and the HMI is developed with VB language to implement the man-machine interaction.Based on the VAIronment software development environment,the core control system is developed with C language to implement such auxiliary functions as system management,data communication, running message management,tag message management and process tracking,with the core set values computed through computation module.The application result in site shows that the system can provide accurate setting values.
