The Analysis And Design Of The Streetlights Remote Monitoring System Based On ZigBee&GPRS

Through the monitoring remote system,city street management technology personnel do not use the "day night patrol line,running lights" manual inspection can through the system can collect remote city LED street lamps and related parameters,and control lights and other functions,to guarantee the normal work of the street.However,due to the previous single light control to the current network control monitoring system development process,many problems are still,For example,if increase the number of street lamp more data at the scene after the patch,will greatly increase the complexity and difficulty of software development,can't meet the needs of remote monitoring technology of communication network now;Due to the street lamp remote monitoring system structure is relatively complex,coupled with a variety of structure in communication network at the same time,which requires the network to integrate the different platform,must implement the communication between each other.It is difficult to solve these problems with traditional methods.Therefore,how to realize the remote monitoring function of street lamp is the most economical and efficient,and it is a new problem we should solve.In this paper,GPRS remote mobile communication technology and ZigBee wireless short-range communication technology characteristics and advantages,to find a ZigBee based wireless technology and GPRS communication technology street lamp remote monitoring system.Combining ZigBee and GPRS two technologies in order to build the street lamp remote intelligent monitoring network,solve the geographic scope of the traditional street lamp remote monitoring system and the limitation of the network mode,can achieve the function of street lamp remote monitoring.Firstly,this paper analyzes the development situation and existing problems of the street lamp remote monitoring system,and draws the main research contents of this paper.Secondly,the design of the system is analyzed,including LED drive circuit,dimming control,monitoring system function composition and control strategy.ZigBee technology has the ability in short distance ad-hoc networks within a small range,which can quickly on a small area of the street terminal data acquisition node controller the street terminal data collected through the realization of long-distance transmission and data communication technology GPRS.Then,this paper has a detailed analysis of the structure of the system as a whole,ZigBee network nodes and the GPRS data transmission module of software and hardware design and implementation,the PC software design of remote monitoring.center,and the entire system commissioning and validation.Finally,the analysis and design of the street lamp remote monitoring system based on ZigBee and GPRS are summarized,and the prospect of the follow-up work is also presented.
