基于GPRS与ZigBee的LED路灯智能监控系统设计

在城市照明路灯管理系统中,由于传统的定时或人工控制方法耗工、耗时、工效低,已不能满足现代路灯控制的需求.由于LED路灯节能、高效的特点,被广泛采用.系统采用网络拓扑结构,利用GPRS与ZigBee无线通信组网技术,以AVR单片机（MCU）为控制核心,实时检测环境亮度,并根据亮度等级实现LED路灯照度的自动调节.系统具有手动/自动控制双模式,可根据需要切换,为城市路灯照明系统的监管提供一种自动的高效的节能策略,具有监控、报警、故障诊断、节能等优势.

LED lights intelligent monitoring system design based on GPRS and ZigBee

In the civil street lighting management,the traditional timing or manual controlling approach cannot meet the modern needs of street lighting requirements due to its large labor and long time consumption with low efficiency.LED lights are widely used as of low energy and high efficiency features.The system proposed in this paper is designed in networking topology structure using GPRS and ZigBee wireless communication technology,takes an AVR microcontroller （MCU） as the control core to adjust the brightness of the LED lights automatically with the surrounding brightness detected in real time.The system can work in two different patterns by the requirement,automatic or manual operation,and offers an automatic and efficient energy-saving strategy for the civil street lighting system with the advantages as real-time control and supervisory,alarming,fault diagnosis,energy-saving,and so on.
