摘要
通过开发电子教室中的电子白板系统代替传统教学中的黑板教学,从而大大提高教学的质量和效率。使用DCOM技术设计和实现了电子教室中的电子白板功能,使用连接点和接收器完成白板操作。已经实现的电子白板系统具有较好的交互性和实时性,经运行测试,能够满足基本的教学需要。DCOM作为COM的扩展,具有位置透明性、网络安全性、跨平台调用的优点,而且DCOM本身已经处理了底层网络协议的所有细节,他的连接点和接收器技术非常适合于开发像电子白板这样的多用户协作程序。
By developing electronics white- board system instead of traditional black board teaching in the electronics classroom, the quality and efficiency of teaching are improved greatly. The function of electronics white - board in the electronics classroom is designed and realized by using DCOM, and it＇ s operation is accomplished by using connection point and receiver. Through testing, it possesses better interactivity and real - time, and can satisfy the basic teaching＇s needs. As the extension of COM, DCOM possesses seat transparency, network safety and the call by striding terrace, and itself has dealt with all details of first floor networking protocol, its connection point and receiver technology are fit for developing multi - users＇ cooperation program like the electronics white - board very much.
