Abstract
The current consumption method of Electric Power Industry is “electricity consumption first, paying for it later”. The trend of consumption method is Pre-order Electricity. If we adopt the Pre-order Electricity System, we need to replace Traditional Energy Meter with Prepayment Energy Meter. But this alteration is costly. And the alarm action of Prepayment Energy Meter are bells and alarm lamp, users can not receive alarm information timely. In this paper, we present the design of Multi-user Electric Power Management Device. The device uses TMS320F2812 as CPU, with peripheral devices such as mobile phone communication module MC55, so the device supports remote operation and sends alarm information via SMS, it also can communicate with the master station by GPRS. The device can be seamlessly integrated into the existing power system in order to read meter, achieve billing and Pre-order Electricity functions. In addition, the device has the Harmonic Measurement function, so it is a high cost-effective application.

Summary
The current consumption method of Electric Power Industry is “electricity consumption first, paying for it later”. If we adopt the Pre-order Electricity System, we need to replace Traditional Energy Meter with Prepayment Energy Meter. The most alarm action of IC card Prepayment Energy Meter are bells and alarm lamp, users can not receive alarm information timely. The device can collect Energy Meters’ electric energy information via RS485 Communication Interface or Pulse Collection Interface, and do electricity charge calculation, choose alarm operation or power on/off operation according to the balance, and there is a SMS notification after every operation, so users can receive alarm and operating information timely. The device can collect many Energy Meters’ electric energy information via RS485 Communication Interface, to achieve Multi-user Electric Power Management purposes. The device has the Harmonic Measurement function, so it is a high cost-effective application
