【摘要】：由于社会的快速发展,人均能源需求量也日趋增加,进而产生了能源资源短缺和环境污染等一系列急需解决的问题,研究低污染、可再生的新能源及其发电技术引起了各国的关注,尤其是风光互补发电技术已成为了目前各国的研究热点,其中具有代表性的风光互补路灯照明系统已在一些地区投入使用,但由于研究还不够深入,出现了性价比不高、寿命短、智能化监控水平低等问题。针对一些风光资源较丰富的中小型城市,在路灯照明系统使用新能源路灯之前的过渡阶段,设计了一种交叉式结构路灯监控系统：在公路两侧,一侧保持常规LED路灯不变,另一侧全部替换成风光互补LED路灯,采用ZigBee和GPRS两级网络结构,对交叉式路灯系统进行监控,实现对路灯的智能化管理,使得在节约电能的基础上提高路灯的供电可靠性。首先,阐述了风光互补发电技术、路灯照明监控系统的研究现状和ZigBee及GPRS无线通信技术的理论,分析了风光互补LED路灯系统的组成部分和目前存在的问题；其次,提出了交叉式结构路灯系统的构架,对基于ZigBee和GPRS的交叉式风光互补路灯监控系统进行了总体设计,包括交叉式结构路灯系统的网络拓扑结构、组网流程、采用Cluster-Tree与AODV算法相结合的改进路由算法和通信协议部分；再次,设计了路灯监控系统的硬件电路,包括风光互补LED路灯终端节点电路、常规LED路灯路由节点电路和子网网关电路,其中终端节点、路由节点和网关内协调器的核心控制器均选用了CC2430芯片,路灯节点电路包括无线射频电路、供电电路、数据采集电路和LED路灯驱动控制电路；最后,设计了路灯监控系统软件部分,包括路灯节点的控制流程、子网网关工作流程和主控中心的监控流程。设计的交叉式风光互补路灯监控系统在节约电能的基础上,整体上提高了路灯的供电可靠性。
[Abstract]:As a result of the rapid development of society, the per capita energy demand is increasing day by day, resulting in a series of urgent problems, such as the shortage of energy resources and environmental pollution, and the study of low pollution. Renewable new energy sources and their power generation technologies have attracted the attention of all countries, especially the wind-to-wind complementary power generation technology, which has become a research hotspot in various countries at present, in which the typical wind complementary street lamp lighting system has been put into use in some areas. But because the research is not deep enough, there are some problems, such as low cost performance ratio, short life span and low level of intelligent monitoring. For some small and medium-sized cities with abundant scenery and resources, a cross structure street lamp monitoring system is designed during the transition period before the street lamp lighting system uses new energy sources: on both sides of the highway, one side of the street lamp remains the same as the conventional LED street lamp. The other side is replaced by the LED street lamp with complementary scenery and adopts the network structure of ZigBee and GPRS to monitor the cross type street lamp system to realize the intelligent management of the street lamp and to improve the power supply reliability of the street lamp on the basis of energy saving. Firstly, the paper expounds the research status of wind power complementary generation technology, street lamp lighting monitoring system and the theory of ZigBee and GPRS wireless communication technology, analyzes the components and existing problems of the wind complementary LED street lamp system. The architecture of cross structure street lamp system is put forward, and the overall design of cross type landscape complementary street lamp monitoring system based on ZigBee and GPRS is carried out, including the network topology and network flow of cross structure street lamp system. The improved routing algorithm and communication protocol are combined with Cluster-Tree and AODV algorithm. Thirdly, the hardware circuit of the street lamp monitoring system is designed, including the terminal node circuit of LED street lamp with complementary scenery. Conventional LED street lamp routing node circuit and subnet gateway circuit, in which the terminal node, routing node and the core controller of the coordinator in the gateway are all selected CC2430 chip. The street lamp node circuit includes radio frequency circuit, power supply circuit, and so on. Data acquisition circuit and LED street lamp drive and control circuit. Finally, the software part of the street lamp monitoring system is designed, including the control flow of the street lamp node. The work flow of the subnet gateway and the monitoring flow of the main control center. The design of the cross wind complementary street lamp monitoring system improves the power supply reliability of the street lamp on the basis of energy saving.
