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.
