The emergence of smart meters is inevitable .Respect to the traditional mechanical meters, Smart meters is higher precision, further more, the smart meters have the function such as achieve multirate billing, automatic meter reading, prepaid fees .The smart meter have the function of data protecting , event logging and automatic meter reading because of the IC. In this paper, a simple design of smart meters will be made description. It will make the data transfer though GPRS and 485.
