摘要:目前随着我国互联网技术以及半导体技术的飞速发展,人们对日常生活的智能化、网络化需求越来越强烈。同时由于快速的发展,能源电力供应存在着短缺的局势,节能发展清洁能源已成为当代发展趋势。LED灯有着使用寿命长,光效利用率高以及节能等特点正在逐渐取代传统路灯照明。目前大部分的大功率LED路灯系统只是最原始的照明方式,并没有智能化的控制系统。有一些路灯可能存在一定的控制功能,但不可以自动完成一些检测照明的任务。本文主要对LED路灯的风力发电、智能监控管理技术,以及ZigBee网络技术进行研究与设计。控制对象使用第四代LED灯具,并集成恒流驱动和PWM脉冲调光技术。控制策略采用ZigBee网络技术,并结合网络拓扑结构的ZigBee Z-Stack协议栈,实时采集LED路灯照明的参数。使用CC2530芯片进行逻辑判断,实现智能调光、分组群控、调色温等复杂功能。同时,采用风力发电,以及铅酸蓄电池与超级电容混合储能方式进行发电。该LED路灯照明控制系统实现了“传感器实时采集,传感网络数据透传,节能绿色能源,上位机集中管理”的设计目标。77923

Design and Development of LED Street Light Control System Based on Wireless Intelligent Information Processing
Abstract:At present, With the rapid development of Internet technology and semiconductor technology in china。People's daily life of the intelligent, network demand more and more intense。 At the same time, there is a shortage of energy and electricity supply because of the rapid development。 And Energy-saving development of clean energy has become a contemporary development trend。 LED lights have a long service life。 The light efficiency and high efficiency and energy saving features are gradually replacing the traditional street lighting。 At present most of the high-power LED street light system is simply a direct lighting and lack the necessary intelligent control system。 Some may have control functions, but can not automatically detect the lighting situation。 This paper mainly studies and designs the wind power generation, intelligent monitoring and management technology of LED street lamp and ZigBee network technology。 The controlling objects use the fourth generation of LED lamps, and integrated constant current drive and PWM pulse dimming technology。 The controlling strategy use ZigBee network technology, and combined with the network topology ZigBee Z-Stack protocol stack and real-time collection of LED street lighting parameters。 Using CC2530 chip logic to determine, to achieve intelligent dimming, group group control, color temperature and other complex functions。 At the same time, the use of wind power, and lead-acid batteries and super capacitor hybrid energy storage for power generation。 The LED street lighting control system to achieve the design goals that "sensor real-time acquisition, sensor network data transmission, energy-saving green energy, the host computer centralized management" 。
