基于Visual FoxPro的CAI课件鼠标智能交互技术

＂继电接触控制系统＂是《电工学》中的重要内容,这部分内容通常需要使用多媒体课件来辅助教学活动以达到预期教学效果。传统的课件通常是使用Office组件——PorwerPoint制作的静态画面,具有难以接受用户交互、难以实时反映电路状态等缺陷。介绍了《笼型电动机直接起动控制线路的电气控制原理》课件的设计过程,讨论了使用计算机高级语言（Visual Fox-Pro6.0）编程手段,实现CAI课件的鼠标智能交互技术,使课件具有能够最大限度接受用户鼠标交互、实时反映电路及电路元件状态等优点,变静态为动态,变单媒体为多媒体,有效化解教学难点。

The Mouse Intelligent Interaction Technology of CAI Courseware Based on Visual FoxPro

"Relay access control system" is very important part of "Electrical Engineering",in order to achieving desired teaching effect,this section commonly use multimedia courseware as supplement.Traditional courseware often use static images which was made by Office components——PorwerPoint,it has many defects such as accepting user interaction difficultly,difficultly to real-time reflecting circuit status and so on.This chapter mainly introduces the design procedure of the courseware"cage motor starting control circuit directly to the electrical control principle",discusses the way how to use computer high-level language(Visual FoxPro6.0) to achieve the mouse interaction techniques of CAI courseware,from this way,the courseware will have many advantages like accepting the interaction of user mouse to it’s maximum,real-time reflecting the state of the circuit or circuit components,changes the Static to dynamic,the single media to multimedia,which to some extent effectively solve the difficulties of teaching.
