面向对象的机械系统虚拟人机界面建模方法的研究

针对机械系统虚拟人机界面的设计问题，应用面向对象技术和方法，将机械系统虚拟人机界面划分为多个相互关联的类和对象，定义了各个类和对象的属性及服务，确定了类与对象之间的层次结构关系，在此基础上搭建了虚拟人机界面的设计构架。选取某一车辆驾驶室人机界面作为设计实例，验证了面向对象的机械系统虚拟人机界面的建模方法。结果表明：该建模方法能够实现对人机界面各个元件的组织管理，正确体现各元件的相互关系。应用面向对象的建模方法可以提高机械系统虚拟人机界面设计软件系统的可靠性、可维护性和可扩充性。

Modeling method of virtual human-machine interface in mechanical system based on object-oriented technology

Applying object-oriented technology, virtual human-machine interface in mechanical system was defined by interdependent classes and objects, whose attributes and services were defined and hiberarchy relationships among which were confirmed. And then the frame of virtual human-machine interface was constructed, and its object-oriented design was realized with the aid of computer. Through this method, the human-machine interface of a vehicle cab was designed as an instance. Results showed that every element of the interface could be managed easily, the relationships among elements could be expressed clearly, and the dependability, maintainability and expandability of human-machine interface were improved.
