| Abstract: | Data acquisition for harmonic power is realized by combination of embedded system's hardware and software.The core of hardware is S3C2440 of ARM9 as the main control chip and the software takes real-time embedded operating system(μC/OS-II) as operation platform.Signal conditioning circuit module and others were designed and the driver and application programs were written.Acquitted data were analyzed and processed after Fast Fourier Transform and processed harmonic component was shown and saved to realize the function of this system. |
