| Remote wireless data acquisition and transmission technology in real-time digital communication technology has been used in industrial production. At present, although the power system to realize the remote meter reading function, saving a lot of manpower, but most of the remote meter reading using wired communication mode, line maintenance workload is large, the communication quality is high, if the special transmission line information. In the user terminal to collect information, using the method of wireless communication will use electric information is passed back to the switchboard, avoid the communication lines maintenance work, increase the flexibility of the data acquisition. Mature application and development of mobile wireless data communication network for the wireless transmission of electric power information provides technical feasibility, construction and stable operation of GPRS mobile wireless data communication network based on to the safe and reliable transmission of power data to provide a guarantee.China’s traditional power meter reading work generally adopts the artificial method, by power distribution company personnel responsible for each community or township, records for each of the electric energy data, this method not only exist meter reading errors. Due to the large workload of manual meter reading error rate the disadvantage of high, State Grid Corporation and some power R & D units began very early meter reading system, and carried out the application of remote meter reading in many areas. The remote meter reading of the early morning is limited to the recording, and the function is single. This stage of remote meter reading system can not only record power user consumption information, but also has monitoring functions, have a certain awareness of environment of electricity can predict failure or find fault in a timely manner.Main content: wireless remote meter for power users and power companies have what practical significance, the research and development of wireless remote meter reading system to transfer and wireless remote meter reading system in Fu Shun the application of Power Supply Bureau.Analysis of wireless remote meter reading system development process, summed up the wireless remote meter reading system, the key technology. According to the demand of electric power users, and the overall scheme design of the remote meter reading system is analyzed. Study the electric power measurement theory, design the electric power metering circuit. Study the main communication theory, design wireless remote meter reading system of communication circuit. Data center system design, research data center management system development environment and development tools, data center communication program design.Analysis of the characteristics of power users in Fushun area, according to the power users, the distribution characteristics and mobile base station location, a reasonable choice of the mode of operation of the wireless remote meter reading system data accurately hair back to the data center. |
