摘 要： 针对当前的照明系统存在智能化程度低、调节能力差的问题，导致能耗较高，提出一种基于ZigBee无线传感网络的智能照明系统设计方法，根据外面环境中的亮度、能见度、污染物浓度等参数构造智能化控制模型，以照明系统的输出功率为约束条件，引入占空比控制算法，对最佳节能点进行寻优，通过迭代计算，配合传感器节点硬件模块进行智能化调节。以真实模块为例进行测试，设计的系统可以智能化地调节照明系统的工作条件，最大程度的节约能源，达到实用要求。

Abstract： Since the energy consumption is high in the intelligent illumination system due to the low intelligent degree and poor adjustment ability of the current illumination system， a design method of intelligent illumination system based on ZigBee wireless sensor network is put forward. According to the brightness， visibility， pollutant concentration and other parameters in the outside environment， an intelligent control model was structured. Taking the output power of the illumination system as the constraint condition， the duty ratio control algorithm is introduced to search the optimum energy?saving point， and marched up with the hardware module of sensor node by means of iterative calculation to perform the intelligent adjustment. The real module taken as an example was tested. The designed system can adjust the working conditions of the illumination system intelligently， save the energy to the maximum extent， and meet the practical requirements.
