Design And Application Of Remote Meter Reading System Based On GPRS

Electricity is wildly used by society, and it influences all fields of the social economy and the life of people. Electric power industry has been developing rapidly with the fast development of economy. But the current level of the automatic management in electric network is low, especially in numerous users system. The traditional manpower reading mode, which can not response to emergence immediately, is inefficient and has many errors. So it is urgent to improve the quality and security of power supply, and to realize the high effect and exact reading system. The new request is realization of automatic attempering and management in the electric network. In order to resolve the problems, it is necessary to resort to computer technology and new communication technology.This thesis discusses all kinds of Automatic Electric Power Remote Management System and AMR (Automatic Meter Reading) technology in current electric fields, and expatiates on an advanced energy management system which based on GPRS (General Packet Radio Service) and relevant technology. The Automatic Electric Power Remote Management System based on GPRS in the thesis includes three central parts: client computers and service computer, GPRS network, concentrator and readers. All of them create a network communication system which is managed by MIS (Management Information System) with protocols of lays and embedded software. The system in the thesis is improved on current similar systems, in which terminal assets mainly use ARM and embedded system technology, and it is more adaptive to the electric innovation.The frame of this thesis is arranged as follows: firstly it introduces the definition of administration of electric power management and relative background of development, and the characteristics of current technology and products; secondly introduces the whole design of the electric power management system based on GPRS and embedded technology; thirdly analyzes the functions of the system, and introduces the software realization of every part such as client computer ,service computer, and reading terminal; finally summarizes the system based on GPRS in the thesis, and describes the trend of the system. Also the author hopes to provide some helpful experiences for relative workers.
