随着互联网、传感器、多媒体等技术的快速发展，许多学校构建了现代化的多媒体教室，利用先进的网络拓扑 架构将音响、麦克风、投影仪、服务器、显示器等设备集成在一起。多媒体教室的运行将会产生不兼容、效率低、音响输出不正 常等软硬件资源问题。传统的被动维护模式影响多媒体教室正常使用，亟需利用传感器、视频监控和数据挖掘等技术构建新 型多媒体教室维护创新模式，实施主动型的运行维护模式，提高多媒体教室建设和维护的成效。

With the rapid development of the Internet, sensor and multimedia technology, many schools build modern multimedia classrooms, using the advanced network topology to integrate the audio, microphone, projector, server and display together. The operation of multimedia classroom has the defects of incompatibility, low efficiency, abnormal sound-output, etc. The traditional passive maintenance mode affects the normal use of multi-media classroom. It is urgent to construct innovation mode by using sensors, video monitoring and data mining in the multi-media classroom to carry out the active maintenance. The innovation mode can improve the effectiveness of multimedia classroom construction and maintenance.
