基于ZigBee的智能教室监控系统设计

Design of Intelligent Classroom Monitoring System Based on ZigBee

为了提升智能教室的设备利用率和维护效率,设计了基于ZigBee的智能教室监控系统。该系统由部署在教室里的传感器采集教室信息,通过ZigBee网络将信息汇聚到协调器,并经过STM32控制中心处理,上传到远程数据库进行管理。用户通过登录系统,能够实时监测教室里的环境,远程控制设备开关,并能在管理界面预先设定环境阈值,实现设备的自动化管理。同时,在教室外连接液晶显示屏,数据经过网关处理之后显示在显示屏上,用户可通过显示屏查看室内人数、温度、湿度等数据信息,从而帮助督导查课、学生快速找到合适的自习室。经测试,该系统操作简便,能够稳定地采集教室信息、准确控制设备,具有较好的实用前景。

In order to improve the equipment utilization and maintenance efficiency of the smart classroom, a ZigBeebased smart classroom monitoring system was designed. The system collects classroom information by sensors deployed in the classroom, converges it to the coordinator through the ZigBee network, and processes it through the STM32 control center, and finally uploads it to the remote database for management. By logging in to the system, users can monitor the environment in the classroom in real time, remotely control the switch of equipment, and can preset environmental thresholds on the management interface to realize the automatic management of the equipment. At the same time, an LCD screen is connected outside the door of the classroom, and the data is displayed on the screen after being processed by the gateway. Users can view the umber of people in the room, temperature and humidity and other data information through the screen,so as to help supervisors check classes and students quickly find a suitable self-study room.The test results show that the system is easy to operate, can stably collect classroom information, and accurately control equipment, which has a good practical prospect.
