| Abstract: | Design of data acquisition system based on embedded technology is introduce, h mainly contains two parts, the hardware and the software. The hardware mainly contains microprocessor chip SEP4020, pre - amplifiers processing electric circuit, the AD transformation chip, the USB connection chip and so on. The software adopts operating system μC/OS- It and VI. In the analysis of the Surface EMG pre-amplification processing electric circuit design, the embedded real-time operating system μ C/OS-]] transplant and the structures of VI is taking as the focus. This data acquisition system has a good real time perfmaance on the signal analysis,processing, and the display. |
