Design of Intelligent Monitoring System of Electrical Devices for Teaching Buildings Based on Internet of Things

摘要:

针对校园用电严重浪费问题,为实现校园节能,结合物联网和多种数据传输技术,设计了一种对学校教学楼各教室内电器集中化、网络化和智能化的监控系统;该系统以监控网关为自动控制中心,对ZigBee网络的终端节点采集的每个教室光强、温度、人员活动以及所有教室常用电器开关状态等信息,自动做出智能判断并向ZigBee网络终端下达开关常用电器以及门窗的指令；同时,连接至校园网的监控网关也作为服务器,采用浏览器/服务器和客户端/服务器模式,在Windows客户端、Android手机客户端和Web浏览器实时远程查看每个教室用电器的工作状态,并可以远程人为干预各教室门窗和用电器的开关;该系统不但实现了远程人为控制用电器,而且可根据各教室的光强、温度以及人员活动等情况,自动智能控制每个教室内常用电器及门窗的开关;实际测试表明,该系统具有良好的可靠性和稳定性,大大减少了校园的能源浪费。

Abstract:

Aiming at the waste of electric energy and reducing energy consumption in university, a centralized, network and intelligent monitoring system for the electrical devices in the classrooms in the teaching buildings of schools is designed in combination with the Internet of Things and various data transmission technologies. As the automatic control centre of the system, the monitor gateway can do intelligent judgments with the data sent from the terminal sensing unit concerning illumination intensity, temperature, activity of students and switch states of every electrical devices in all classrooms. Meanwhile, using the Browser/Server and Client/Server mode, the monitor gateway connected with campus network can act as server,and the operator can view the working states of every electrical devices and control the switch of every electrical devices, windows and doors in all classrooms in real time by the Windows client, Android client and Web browser. Not only can the electrical devices in one classroom in the teaching buildings of schools be controlled remotely with human intervention,but also can be controlled automatically and intelligently with the light intensity, temperature and human activity of this classroom by this system. Practical tests show that the system has good reliability and stability, greatly reducing the campus waste of energy.
