面向对象的中厚板轧线模拟系统设计开发

摘要

为实现轧线自动化系统离线调试和优化目的,开发了中厚板轧线模拟系统.应用面向对象技术进行模拟系统设计,将轧线划分为设备对象、仪表对象和轧件对象.单体对象通过封装的服务更新自身属性,通过开放的公共属性建立对象之间的关联.基于过程控制系统平台环境进行模拟系统开发,采用多线程结构满足中厚板轧线多个工艺区域的模拟要求,以时间触发器控制模拟时间步长,采用实际数据回放方法产生模拟系统的轧制工艺数据.模拟系统实现了从坯料上线开始到轧制结束生产过程的模拟,设计开发的中厚板轧线模拟系统已应用于实际工程项目,满足了轧线自动化系统的离线调试要求.%Simulation system was developed, in order to achieve the purpose of offline functional debugging and optimization for the plate rolling line automation system. For the system, it was designed based on the object-oriented technology. Plate mill line was divided into equipment object, instrument object and plate piece object, in which single object attributes are updated by private service and different objects are associated through public property. Based on process control system platform environment, multi-thread structure was used to meet the simulation requirements of multiple process areas. Time trigger was used to control simulation time step, and actual rolling process data can be generated through data playback method. The process from putting slab online to end of rolling was simulated. The developed simulation system was used for one practical project, and the offline commissioning requirements were satisfied well.
