针对现有教室能源管理的不足,提出一种教室灯光监控系统.系统依托CC2530嵌入式硬件平台,采用Contiki操作系统搭建6LoWPAN协议栈,建立可自组网的无线传感器网络.节点集成光照度和人体红外传感器,并添加相应的资源供外部访问,采集的数据通过网关节点发送至监控中心,实现无线传感网络接入互联网.在此基础上,采用Node.js技术屏蔽由于网络环境不同导致的应用层协议不兼容问题,实现B/S模式的监控系统.结果表明:该系统可以在互联网环境下对系统资源实时访问,实现对教室照明情况的实时监控.
Aiming at the shortcomings of existing classroom energy management, this paper proposes a classroom lighting monitoring system.The system relies on CC2530 embedded hardware platform to build a 6LoWPAN protocol stack by using Contiki operating system to establish a self-organizing wireless sensor network.The nodes integrate illumination and human infrared Sensors, and add the appropriate resources for external access, the collected data is sent to the monitoring center through the gateway node to achieve wireless sensor network access to the Internet.On the basis of using Node.js technology to shield the application layer due to different network environments Protocol incompatibility and realize B / S mode monitoring system.The results show that the system can access system resources in real time under the Internet environment and real-time monitoring of classroom lighting conditions.
