基于Zigbee的自动演示实验教学系统的设计

Design of automatic demonstration teaching system based on Zigbee

针对当前高校演示实验教学的特点,设计了一种以Zigbee无线网络为载体的演示实验自动教学系统。该系统具有自动教学、讲解清晰、讲解同演示设备同步等优点。系统采用主从方式,由教学播放器、从控制器、无线射频遥控器组成,能同时连接128台讲解实验设备,可全天开放实验教学,无需教师参与,提高了教学质量,减轻了教师教学负担,同时提高了学生参与实验的积极性。

According to the characteristics of the experimental teaching, an automatic demonstration teaching system based on ZigBee wireless network is designed. The system has the advantage of automatic teaching without human, speak clear, synchronize with experimental equipment and etc.. The system adopts master-slave mode, including audio player, slave controller and RF remote controller, it can connect 128 experiment equipments together. The lab which install this system can be opened during daytime for the whole campus students, without teachers to participate in. And also can improve the quality of teaching greatly, reduce the burden of teachers in teaching, and let students be positive during the experiment.
