Research And Design Of Street Lamp Monitoring System Based On Wireless Network

With the rapid development of urban construction,the scale of the infrastructure of the city street lighting is constantly expanding.The load of the existing street lamp monitoring system becomes more and more big,which not only makes the management and maintenance of the street lamp more difficult,but also causes the huge waste of energy.In the field of industrial control,the remote control and intelligent control system can effectively improve the efficiency of control management and reduce maintenance costs,which has gradually become a trend of development.At present,most of the domestic city street lamp management still uses traditional way.Especially in the street lamp maintenance it is unable to realize the real-time monitoring of each lamp lights.The progressive realization of intelligent city streetlight monitoring and management system is very necessary.In order to realize the intelligent control system,this paper presents the design and implementation of street lamp control management system based on wireless network.In this paper,three-layer-distributed streetlight monitoring system is designed,including the monitoring center,data concentrator and single lamp control terminal.The system adopts GPRS wireless communication technology and power line carrier communication technology.The street lamp monitoring system can realize the remote monitoring and management of street lamps,especially the single lamp monitoring system.This system is suitable for the traditional high pressure sodium lamp and transforms the traditional street lamp control system,which can realize the intelligent control and management system of street lamp,in order to achieve the goal of saving energy and reducing the maintenance cost.Firstly,by investigating the research status of urban street lamp monitoring system at home and abroad,this paper analyzes the practical significance of the system in practical application combined with the actual demand of domestic street lighting system.Secondly,the street lamp monitoring system in the communication technology and the existing schemes are compared.The overall design of the monitoring system is carried out,combined with the system functional requirements.Then,it focuses on the two aspects of the hardware and software of street lamp monitoring terminal,including the development of communication protocol,the design of GPRS module and power carrier module,the software and hardware design of the monitoring terminal,etc.Finally,the function of each system is tested and the whole test is carried out,which can realize the remote monitoring and management function of cluster and single lamp.The design work of this paper mainly includes the construction of the system environment,the design of hardware and software of the monitoring terminal,the development of the communication protocol,etc.In order to ensure that the bottom monitoring terminal can achieve effective network,the communication protocol is designed for the communication of street lamp monitoring terminal based on ModBus protocol.Monitoring terminal software program design is the focus of this paper.The terminal of the software program is mainly responsible for the communication between the terminals,data packet analysis,related control operations,data acquisition and other functions.
