Design of Electric Energy Meter for Long-distance Data Information Transfers which based upon GPRS Technology

With the popularization of Internet in China, as GPRS service improved increasingly, electric energy meter transmits the data information and controlling command remotely and wirelessly. Based on the current electric energy meter, with the well-functioned ARM kernel microprocessor, it not only finishes the power data´s measuring and processing, but also realizes the TCP/IP by cutting. By ARM kernel microprocessor controlling GPRS module, electric energy meter could be linked to the Internet by use of GPRS service. The overall system is stable and reliable because it is managed by mu C/OS-II operating system. This is especially for some outlying areas where the Cable Network hasn´t been popularized. It not only raises the efficiency of electric energy meter data information´s acquisition and transition, but also the national measure management of electric energy improved greatly.
