以无线传感器网络构建的照明节电系统的设计

Design of a lighting system for energy saving based on wireless sensor network

为实现室内照明灯具的节电需求,采用无线传感器网络技术,设计了智能的照明节电系统,提出了一种照明控制算法,能根据感测到的室内光照度、人的位置信息,对用户所在位置附近灯具的调光指数进行计算,从而自动调节灯具亮度。实验结果表明,当用户进入某区域时,该区域附近的灯具能根据自动计算的调光指数调整亮度,以达到节电的目的。

For energy saving of indoors lightings, an intelligent lighting system for energy saving using wireless sensor network technology was designed. A lighting control algorithm,which can calculate the dimming factors for the lightings near user＇s position by indoor light intensity and people position information, was proposed. Using the algorithm, the system can adjust lightings brightness automaticly. The test results indicate that the system may fulfill the goal of electricity-saving since the lightings near the region can adjust lamp brightness automaticly by the dimming factors of automatic computing when a user enters an region.
