Qingchun Zhang

Abstract

Aiming at demands of the data acquisition device with high performance-to-price ratio from engineering and teaching experiment system,a data acquisition system is designed.It adopts Labview graphical development software,high-precision and high-speed data acquisition device MAX197,8051 microcontroller and USB interface that integrated into the chip CY7C68013.It achieves the 8 channels 12-bit data acquisition,1 channel 8-bit D/A output and 16 channels digital I/O.Also it can display the detected temperature.A/D maximum sampling frequency can be 100kHz.This data acquisition appliance has the high performance-to-price ratio.It may be propagated in applications.
