Research On Networked Monitoring System Or Solar LED Lighting

With the growing of energy crisis and the development of city lighting, solar LED lighting as akind of green environmental protection lamps and lanterns, has applied more and more widely. Dueto solar LED lighting system affected by light and temperature and other random environmentfactors, therefore the solar LED lighting need to have a complete monitoring system to monitor theparameters.Through analyzing the status and trend of monitoring lighting, and characteristics of solar LEDlighting component, combined with their respective advantages of wired and wireless datatransmission, this paper gives a solar LED lighting control system scheme which is the two type ofnetwork data transmission structure combining CAN with GPRS.According to modular design concept, it designs hardware and software module of lowerterminal node based on STM32F103VCT6controller, completing data acquisition and bottomcontrol and data network transmission task. Based on the theory of network programming, andthrough comparing the advantages and disadvantages of B/S structure and C/S structure, this paperchoose C/S structure which is good real-time interactive, powerful function and high security, todesign upper monitoring software in VS2008environment. In order to meet the need of highconcurrency communication requirements of server software and client software, GPRS node, theI/O model of server software adopts completion port model. According to the data storagerequirements, using ACCESS2003database to store data for interacting with the server software.On the basis of user experience requirements, it designs the client software in NI MeasurementStudio environment which provides a simple and friendly management interface, completing theissuing of user control instructions and displaying of monitoring information and other tasks.It designs, manufactures and debuggs hardware system, and gives the designing of main features of the uppersoftware modules.The functional and performance test for the whole system has been done.The results showthat, the scheme is feasible, and the monitoring system can complete the monitoring task, and theserver software based on completion port model is superior to the traditional model of serversoftware.
