基于CORBA面向对象的FMS控制系统模型

A CORBA-Based Object oriented Model for FMS Control

为了使ＦＭＳ控制软件系统具有开放性，本文提出了基于ＣＯＲＢＡ 面向对象的ＦＭＳ控制系统模型，将相关可编程设备的物理单元抽象为对象。为了方便异构物理单元的集成，各个物理单元对象通过继承抽象单元类共享公共通讯协议（ 单元与单元之间及单元与总控制器之间通讯协议） 。此外，ＦＭＳ的其它相关物理和抽象实体也抽象为对象。为了证实本文提出的控制模型，在ＶＣ＋ ＋ ５ ．０ 编程平台下编制了ＦＭＳ控制软件，并在上海交通大学生产与控制技术研究所ＦＭＳ示范系统进行了检验。

In searching for an open architecture for the FMS control software system,this paper proposes a CORBA-based object oriented FMS telegraph and data model.Among others,it represents each physical cluster of related machinery as an object.To facilitate the integration of heterogeneous physical cells,such cell objects share a common protocol of interacting with the main control process through inheritance form the abstract cell class.Other related physical and abstract entities in FMS are also modeled as objects.To verify the proposed CORBA-base object oriented model for FMS control,a prototype FMS control system has been implemented in VC++5.0 and has been tested in connection with the physical FMS shop at the Production System and Control Technology Institute of Shanghai Jiao Tong University.
