The design of the multifunction power quality monitor

According to the IEC and national standards, the powerful data-processing capability of DSP and the high precision A/D data acquisition chip are used for data synchronous acquisition and analysis, monitoring values are computed in the DSP which communicates with ARM via serial port and FIFO. Making full use of some characteristics of ARM module, such as its high performance and ample periphery interfaces. And embedding with excellent real time operating system-Linux is also applied to complete statistics, analysis, storage, communications, display the power parameter after processing. This power quality monitor adopts advanced and reasonable hardware framework of superstratum plus substrate machine, making the work division in the monitor more clear and the function more strong.
