摘　　要：介绍了一种三相电能计量系统,具有精度高、智能化的特点,能够测量各相有功电能、无功电能、电流及电压有效值等参数,采用Freescale单片机为主控芯片,辅以专业计量芯片和外围电路,降低了成本,提高了设备的可移植性和可靠性。系统还可以与上位机进行通信,实现智能化。In this paper, a three-phase energy metering system is introduced, it is an intelligent and high precision system. This system has functions of meter all phases active energy, reactive energy, current rms, voltage rms and so on. The metering system is designed with freescale single chip and professional metering chip and peripheral circuits, it decreases the cost, improves system portability and reliability. The intelligent system can also be cowmunicated with the host computer.
