| Abstract: | A kind of high speed multi channel data acquisition system based on AD7865 is introduced in this paper and the data acquisition system hardware circuit and GAL（ General Array Logic）program are designed too. Based on AD7865 analog- to - digital converter, an analog quantity input channel circuit and digital interface circuit design of the data acquisition system are completed and at the last, high speed and accuracy multi channel data acquisition system is realized in the computer numerical control＇s gear measurement. |
