间歇式液相本体聚丙烯装置计算机控制与管理系统

The Computer Advanced Control and Administration System for Batch Liquid Phase Bulk Polypropylene Plants

介绍一种间歇式液相本体聚丙烯装置计算机先进控制与管理系统。它是由"基本控制层"和"上位控制层"构成的经济适用型集散控制装置。该装置采用了多屏显示技术、网络通讯技术、PLC程控技术、ActiveX控件技术和面向对象程序设计方法、数据库技术以及闭环辩识、预测控制、反应优化、底层PID控制与上层先进控制无扰动自动切换等多种技术和控制方式,因而可以灵活有效地实现聚合反应的全过程自动化生产和安全保护。

A computer advanced control and administration system for batch liquid phase bulk polypropylene plants is introduced. It is a low cost integrated and distributed control system composed by a downlevel basic control layer and an uplevel advanced control layer. The system adopted several new technologies such as multiscreen display,network communication,programming logic control,active components,database,closed loop identification,predictive control,non disturbance switch between PID and advanced control,and so on. Therefore,it effectively realizes the automation production and safe protection of polypropylene plant.
