摘要
为了方便教师授课时掌握当节课剩余时间,提高教学效率,并可对时间进行远程校准,设计了一种以TI(德州仪器)公司的CC2530芯片为核心的基于ZigBee技术的教学时间管理系统。利用实时时钟芯片(DS1302)作为基准时间,对系统预先写入课程时间表,实现自动记录北京时间与当前课剩余时间。构建ZigBee无线网络,控制中心可远程对各节点发送控制命令。分析了系统的工作原理、硬件设计、软件流程。实验结果表明,该系统能够可靠的完成数据的采集与处理,并实现远程控制,提高了系统的实用性。
In order to help teacher master the remaining time of current class,improve teaching efficiency,the time can be calibrated remotely.A teaching time management system is designed.Real-time clock chip （DS1302）is used as reference time,the system is pre-written curriculum schedule,and recording the Beij ing time and remaining time.ZigBee wireless network is built to send control commands to each node.The working principles of the system,the hardware design and software workflow are analyzed.The experiment turns out that the date acquisition and procession can be done by the system reliably,and remote control is realized,improving the applicability of the system.
