摘要
采用ZigBee技术,进行了LED智能照明系统设计与开发。在LED路灯上加装传感器模块,检测环境的照度、温度的变化以及行人、车辆的活动状况,并采用ZigBee模块对LED路灯进行组网和数据传输,进而完成了以对传统LED路灯系统实现自动控制及节能降耗为目的的智能化改造。在进行系统整体设计开发的同时,为解决实际系统中的传感器误报、漏报,协调器负担过重,数据拥堵以及节点掉网等关键问题,采用软判决、节点绑定、点对点通信以及节点的掉网检测及重新入网等方法,提高了系统的稳定性。通过该系统方案的设计开发及示范系统的搭建与验证,实现了LED路灯的无线组网,依据环境照度变化自动控制系统的开启与关闭,对LED路灯的自动、手动控制的切换,依据行人及车辆的活动状况进行相应LED路灯的联动调光,对LED路灯状态进行监控与管理等功能,并达到了节能降耗的目的。
This paper presents the design and development of LED intelligent lighting system by using ZigBee technology.In order to detect the variation of brightness,temperature,pedestrians and vehicles,sensor modules are added to the LED street lamp,and ZigBee modules are used to construct wireless network and data transmission.It realizes intellectualized reconstruction of traditional LED lamp system based on the purposes of automatic control and energy saving.At the same time,in order to solve the problems of misstatements and omission of the sensors,overload of the coordinator,some solutions are used to enhance the stability of the system,such as soft decision,node binding,point to point communication,and detection of the enter/drop from the wireless network.Experiment results show that the intelligent LED lighting system realized network construction,system automatic on/off according to environmental illumination,automatic/manual switching,ganged lighting control,and system management and status monitoring.
