Design And Realization Of Public Lighting Remote Monitor Equipment

The controlling method for traditional public light system cann't satisfy the needs of modern city, for the questions exiting in it such as low efficiency, high cost, unable to monitor. Along with social and technical unceasing development, the characters of advanced public light remote measuring and controlling system are automatic, reliable, saving and convenient, the public light remote computer supervisory system has already become municipal administration vivid project which various municipal governments care for extremely. In this paper, within the analysis of extant public light supervisory system's function and the society request to the public light control management, studing the working principles, functions and characters of the public light remote measuring and controlling system, we unify with the aid of the automation control and data acquisition system and the advanced communication technology—GPRS wireless communication. Also a new public light remote measuring and controlling device is designed, which the real-time computer measuring and controlling of the urban public light is realized.This equipment use the MSP430F149 of TI company as MCU, which the detection and control of contactor status,voltage,current are realized. The equipment connects to monitor center via GPRS wireless remote communication method. Also it can receive monitor center command, upload the data to monitor center, and on the basis the communication protocol is made. The LCD HMI is designed, so users can check the public light establishment status. Besides, the MCU serial port is extended, which realize the cable anti-burglary function based on power line carrier technology and remote meter reading function base on DL/T-645 protocol, so users can know the locale status and adopt measures to solve problems.The first chapter has first summarized briefly the system project background, the situation and development of domestic and foreign street lights supervisory system and my main work. The second chapter analyse the advantadges and disadvantadges of different remote communication method, combined with public light remote measuring and controlling system functions and pricinples, determine the general design scheme. The third chapter describes the hardware design of public light remote measuring and controlling device in detail. The forth chapter analyze the entirely structure and the implement method of public light remote measuring and controlling device. The fifth chapter studys the configuration scheme and functions of center monitor software. The sixth chapter introduces the realization of public light remote measuring and controlling device. At last, we summarize the article.
