Research Of Wireless Monitoring And Management System Of City's Street Lamps

The street lamp lighting is an important part of municipal infrastructure, and it holds the vital position in traffic safety, social security, people's life and city's, appearance and scene, also it indicates the degree of city's strength and maturity. So it is an inevitable appeal and a significant symbol of lighting control and management to design a kind of lighting system, which has the advantages of high automation and reliable operation and can save power energy efficiently. Fortunately, the development of modern computer centralized control technology gives us an efficient path to solve the problem. The wireless monitoring and management system of city's street lamps is the efficient and inevitable product of the application of the modern computer technology to the municipal construction, and it realizes computer centralized monitoring, control and management.The wireless monitoring and management system of city's street lamps performs monitoring and control to the city's street lamps together by wireless transmission and computer. It is composed of one monitoring center, several monitoring terminal mainframes, several monitoring terminal inferior-frames and communication equipment. The communication mode between the monitoring center and each monitoring terminal is the General Packet Radio Service. The monitoring terminal mainframes and inferior-frames adopt power line carrier communication technology to realize data exchange. The human-computer interface of the monitoring center is organized by ASP+SQL Server which has powerful functions and can be maintained conveniently. This system can not only improve efficiency, short repairing time, reduce maintaining cost but also realize the control management by time and stages, decrease electricity expenses greatly. And it will produce giant social and economic benefits in saving energy, protecting environment and guaranteeing social security.The main work includes several hereinafter points:1. Research the developmental status of the monitoring system of street lamps during recent years, and put forward a more advanced and more efficient design scheme.2. Research the composition, business and the wireless DDN system of the General Packet Radio Service to realize the communication between the monitoring center and terminal.3. Research the characteristic, superiority and applied occasion of the power line carrier communication technology, and make it the communication method of the monitoring terminal mainframes and inferior-frames.4. Apply ASP and SQL Server to organize the human-computer interface of the monitoring center and to realize all kinds of functions.
