摘　　要：针对传统教室用电器利用率低的问题,本文基于Zigbee设计了智能教室控制系统,通过Zigbee无线网络,对教室险情监控、人数统计、无线控制灯开关系统进行设计。该系统以STM32单片机为核心,通过Zigbee终端无线接收和发送信号到Zigbee协调器,协调器通过无线网以点播的方式接收和控制每个Zigbee终端的信号,从而进行无线控制,同时通过SIM900实现远程信息传递。实验结果表明,用户可以通过该系统远程实时监测教室环境,控制灯的开关,并通过红外对管统计进出教室的人数。该控制系统便捷灵活、操作简便,达到了预期设计目的,具有良好的经济实用前景。In view of the low utilization rate of electrical appliances in traditional school classrooms,this paper designs the danger monitoring,population statistics and wireless control light switch system through Zigbee wireless network.The system takes the STM32 MCU as the core,and wirelessly receives and transmits signals to the Zigbee coordinator through the Zigbee terminal.The coordinator receives and controls the signal information of each Zigbee terminal on the on-demand basis through the wireless network,thereby achieving the purpose of wireless control.Remote information transfer is realized through SIM900.The experimental results show that the user can remotely monitor the classroom environment remotely,control the lights in the classroom,and count the number of people entering and leaving the classroom through the infrared tube.The control system is convenient,flexible and easy to operate,and achieves the intended design goal.The study has good economic and practical prospects.
