Abstract :A new design of DSP + ARM portable power quality monitoring device is proposed in this paper .TMS320F2812 DSP and
high precision AD7656 are used for power quality data synchronous acquisition .Monitoring values are computed in the DSP, which
communicates with ARM S3C2440 embedded with Linux system via serial port and FIFO and transfers power data and computed
values .The data are stored in large capacity storage device and displayed in the LCD .The data transmission between PC and ARM is
fulfilled by network and the operating parameter of monitoring terminal is set .Feasibility and reliability of the device are validated by
experimental test,and the results show that the device is in accord with the electric power quality monitoring standard .
