| Abstract: | The DAQ instrument applied in the automotive road test was studied and developed based on 80C196KC microcontroller.Its hardware circuits,software structure and measure error were respectively analyzed in detail.Due to the design of the high accurate 32-bit hardware timer and the same grade and independent four-channel sampling circuit to the impulse signal in the instrument,the problem of real time to the test system based on Windows and the problem of same grade data acquisition to multi-channel signal were settled effectively.All the experiments indicate that the instrument is of reliable,of high accuracy and of broad application. |
