This paper presents one pre-pay intelligent power metering management system based on ARM Cortex-M3 which is composed of power supply control cabinet and PC server ，between them data transmission is carried out through TCP/IP. The ADE7753AR single energy chip with SPI communication interface is used to design the energy metering module. The embedded ARM processor and STM32F103ZE chip with Cortex-M3 kernel are used as the core of the accounting management controller. The control cabinet is connected to the metering module and the controller through the RS-485 bus, which can achieve higher reliability and the performance price ratio of the system. The centralized management mode is adopted to implement mobile phone campus card pay, which will provide convenient and quick, and has broad application prospect.
