摘要
设计实现了一个基于Zigbee物联网的教室环境监测系统。系统共分为感知层、网络传输层和应用层三个层次。感知层利用热释电红外传感器、光照强度传感器和温湿度传感器采集教室内人数、光照强度、温湿度环境数据;网络传输层采用Zigbee技术构建无线物联网络,通过Zigbee网关服务器,将感知层的环境数据传输给应用层;应用层设计了上位机查询管理软件与移动终端查询软件。实验结果表明,该系统可以实时查询教室内人数、光照和温湿度信息,为教室资源合理调配,室内灯光照明、空调运行的科学管理提供有效依据。
A classroom environment monitoring system is designed and implemented based on Zigbee Internet of things.The system is divided into three layers:sensing layer,network transport layer and application layer.The sensing layer uses the pyroelectric infrared sensor,the light intensity sensor,the temperature and humidity sensor to collect the number of people, light intensity,temperature and humidity information in a classroom.The network transport layer uses Zigbee technology to construct wireless network.Through the Zigbee gateway server,the environment data of the sensing layer is transmitted to the application layer.The application layer designs the host computer query management software and mobile terminal query software.The experimental results show that the number of people in the classroom,light intensity,temperature and humidity information can be real-time queried using this system.Furthermore this system can provide effective basis for the rational allocation of classroom resources,scientific operation of indoor lighting and air conditioning.
