面向对象的FMS控制系统模型与实现

为了使FMS(柔性制造系统)控制软件系统具有开放性,本文提出了面向对象的FMS控制系统模型.模型设计采用面向对象的模块化原则,并基于CORBA标准的面向对象开发平台,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).为了证实提出的控制模型,在VC++5.0编程平台下开发了FMS控制软件,同时以上海交通大学生产与控制技术研究所FMS示范系统为实例进行了验证.

An Object - oriented Model for FMS Control and Implementation

In searching for an open architecture for the FMS control software system, an object - oriented FMS control model is proposed. The object - oriented principles and the standard CORBA development platform are applicated in the design for control model , each physical cluster of related machinery is represented 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. To verify the proposed 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 floor at the Production System and Control Technology Institute of Shanghai Jiaotong University.
