基于无线传感器网络的智能照明控制系统

随着节能、环保概念的普及，绿色照明理念开始推广，智能照明控制系统的需求日益增加。本文的智能照明控制系统由无线传感器网络、OPCDA服务器和用户界面组成。无线传感器网络采用星型结构，由ATmegal6L和nRF905组成网络节点控制LED灯。无线网络中的基站通过RS232连接PC机中的OPCDA服务器。opcN务器将设备状态传递给用户界面，并将接收的控制命令下达给无线网络节点。最后，本文利用nRF905无线模块模拟组建一个智能照明控制系统，运行结果表明，系统具有良好的可扩展性。

Intelligent Lighting Control System Based on Wireless Sensor Network

With the population of energy conservation and environmental protection, the green lighting concept is becoming promoted, and the demand of intelligent lighting control system is increasing. This intelligent lighting control system is consisted of wireless sensor network, OPC DA server and the user interface. Wireless sensor network structure is star-type topology. ATmega16L and nRF905 are used to build the wireless sensor network nodes which connect the LED lights. The base station in the wireless network is communicated with the OPC DA server which is in the host computer by RS232 bus. The OPC DA server is applied to transmit the LED lights states to the user interface and send the control commands to the wireless network nodes. Finally, this article use nRF905 wireless transmitter modules simulate an intelligent lighting control system, the result shows that our system has good expansibility.
