ZigBee＋GPRS的LED路灯监控系统

将ZigBee技术和GPRS移动通信技术相结合，设计了一种基于ZigBee＋GPRS的LED路灯照明远程监控系统。系统采用两级双网组网模型和簇-链型网络拓扑结构，通过网络化、智能化控制，实现了灯具的遥测、遥控。此外，提出了一种应用于路灯照明的亮度自适应节能控制算法，该算法可根据时段、环境亮度和人员活动情况改变PWM信号的占空比，自动调节LED的亮度，充分利用LED的可控性，实现最佳照度控制，达到节能目的。

LED Street Lamp Monitoring System Based on ZigBee+GPRS

Combining ZigBee technology and GPRS mobile communication technology, an LED street lamp monitoring system based on ZigBee-FGPRS is designed. Using two pairs of network models and cluster-chain network topology, the system achieves telemetry and remote control of street lamp through the network and intelligent control. A brightness adaptive energy-saving control algorithm suitable for street lamp illumination is proposed. According to the time periods, ambient brightness and staff movements , the algorithm can change the duty cycle of PWM signal, automatically adjust LED brightess and make full use of the controllability of the LED to realize the best illumination control and energy saving.
