Design Of GPRS Network Energy Meter Based On ADE7758

Along with the development of computer,network and communication technology, various automatic energy meter reading technology is been widely used in distribution network.Combining with China's national conditions, The paper study and design a set of GPRS network energy meter based on ADE7758 .The paper first introduced energy meter development's course as well as the present situation, and elaborated each kind way of energy meter reading and discussed the respective advantages and disadvantages.briefed the future tendency of the energy meter technological development.Then the topic elaborated the network energy meter's goal function,compared to the advantages and disadvantages of various system construction's design proposal at home and abroad to determine the issue of the energy meter construction's design According to need of function, TI's MSP430FG4619 is selected as energy meter's MCU and design energy meter's testing and control system to simplify the design of energy meter's circuit and improve the system's handling ability;Data acquisition part uses electrical energy measurement special-purpose chip ADE7758 to improve the network energy meter's precision;the use of LCD module provides friendly people-machine interface; In the analysis of current commonly used system network construction and the disadvantage and advantage of the embedded turning on plan ,the topic determine the system's network construction and the embedded turning on plan, communication module realizes the electrical energy quantity parameter long-distance transmission through the wireless GPRS MC39i and embedded TCP/IP protocol stack; The calibration of energy meter ensure the accuracy of energy meter.The paper introduced in detail the process of GPRS communication realization.According to system's own need, carried on.the approprite cutting out to TCP/IP protocol stack not only simplified the TCP/IP protocol but also satisfied the network communication's request of energy meter.
