基于图形控件的电气操作票系统的设计

DESIGNING ELECTRICAL OPERATION ORDERING SYSTEM BASED ON GRAPHIC COMPONENT

结合发电厂的实际情况,采用面向对象的软件开发技术,充分利用面向对象技术的封装性、多态性等特性,开发出一套集微机开票与信息管理为一体的操作管理系统。在Visual Basic 6.0开发环境下开发出电气图形控件,其内部封装了丰富的属性与事件,并提供了操作逻辑闭锁功能,具有图形逼真、易于使用等特点。在Visual C++6.0开发环境下设计的开关器件操作类与电气图形控件的接口进行了无缝连接,实现了图形点击开票功能;设计的设备操作类以开关器件操作类为成员,并封装了所有可能出现的操作任务,实现了微机自动开票功能。

Based on practical situation in power plants,a set of operating management system which integrates the function of microprocessor issuing orders and information management together is developed by adopting object-oriented programming（OOP） technology and making full use of the polymorphism and encapsulation of OOP.The electrical graphic control developed in developing environment of Visual Basic 6.0 encapsulates ample properties and events,and provides the function of operation logic interlock,possesses many features such as vivid images and easy-to-use,etc.The switch component operation class designed in developing environment of Visual C＋＋6.0 connects seamlessly with the interface of electrical graphic control,and the function of issuing the order by clicking on graph is successfully implemented.Device operation class designed takes switch component operation class as the member and encapsulates all operation tasks possibly occurring,thus the microprocessor automatic order issuing function is realized.
