针对当前数控系统软件可重用性差的现状 ,本文采用建立面向对象的数控软件模型的方法来提高数控软件的可重用性。在分析数控软件结构的基础上 ,建立了数控软件的通用类库 ,由类的继承性实现各个功能模块代码的可重用 ;采用客户 /服务器模式建立了运行于双CPU、Windows95 /NT平台下的通用对象关系模型 ,并实现了多任务并行调度。实际应用表明 ,该方法是可行的。
In view of the current poor reusability of numerical control system software, this paper adopts the method of establishing object-oriented numerical control software model to improve the reusability of numerical control software. Based on the analysis of numerical control software structure, a universal class library of numerical control software is established, and the reusability of each functional module code is realized by the inheritance of classes. The client / server model is used to establish a dual-CPU, Windows95 / NT platform Universal object relational model, and achieve multi-task parallel scheduling. Practical application shows that this method is feasible.
