Design and implementation of monitoring and control system for hot strip rolling based on VB and SQL

本文设计并实现了带钢连轧监控系统。建立了模拟实际生产线的带钢连轧仿真模型,应用了SQL数据库技术处理大量的模拟仿真数据。介绍了系统实现中的VB平台与SQL2000数据库的连接以及操作技术,建模时用到的查表算法技术和动态绘图技术三个关键技术。系统实现了对连轧过程的带钢入口和出口实际厚度、宽度、温度进行监测,并以动态曲线的形式显示;建立轧制模型,设定各种轧制参数,并将数据保存到数据库中,以便管理及查询;模拟仿真结果反馈控制实际参量,令实际值逼近模型的理想值。

The design and implementation of a monitoring and control system for hot strip rolling is introduced in this paper. The hot strip rolling model which is the simulation of the practical rolling system is built. SQL database technology is used to handle the mass of the rolling data. The linkage and operation method between SQL2000 and VB are introduced, as well as the key technologies for the implementation of the system model： the table look-up technology and dynamic drawing technology. This system can monitor the thickness, width, temperature of the steel strip in the entry or the exit, show them in a dynamic way. Parameters are calculated and set in the model and sent to rolling stands, and practical rolling parameters are feedback.
