Hardware System for Automotive Wiring Harness Testing Based on DAQ Instrument

Abstract:

With the development platform based on Advantech DAQ board, we have completed the design of multi-channel analog switch, decoding circuit and impedance testing circuit and built a good hardware platform for the automotive wiring harness testing system. Testing software is used to import different values into the digital I/O of data acquisition card of the hardware of to choose the tested points and then the voltage signal is read from every loop and the voltage signal is sent into the computer. Analyzing, processing, displaying is done by the testing software so that the hardware system becomes the development platform for Lab-VIEW software application.
