Intelligent Control System of LED Street Lamp Based on ZigBee

设计了一种基于Zig Bee的物联网智能LED路灯控制系统。路灯节点采用AVR单片机作为核心处理芯片,通过光电传感器检测外部信号,可根据环境明暗、交通情况和定时开关等条件以不同方式控制LED灯照明;使用MBI1802驱动芯片恒流驱动LED灯,功率在20%~100%范围内可调,调节误差〈2%,恒流电流偏差〈±1.7%;以Zig Bee无线通信网络与控制中心进行远程控制、故障报警等信号传输,实现了路灯智能化、远程化的节能控制。

The development of LED street lamp control system based on Zig Bee network is presented in this paper. Using AVR microcontroller as the core processing chip, the lamp node detects the external signal by photoelectric sensor, controls LED lamp lighting in a different way according to the environment light, traffic conditions and timing;using the MBI1802 drive chip constantly drives LED lamp, power regulations are in the range of20% ~100%, adjustment error is less than 2%, constant current deviation is less than 1.7%; communication between nodes and center is realized with Zig Bee wireless network, to carry messages of remote control and alarm signal. The results indicate that the system is intelligent, long-distance and energy conservation.
