Software System for Automotive Wiring Harness Testing Based on Virtual Instrument

Abstract

Development of modern information technology provides a technical platform for the wide application of virtual instrument technology. Here we apply virtual instrument technology to test the faults of wiring harnesses, such as short circuit , broken circuit , wiring error , poor contact, poor insulation and unsatisfactory impedance and monitor the product quality at real-time. We use LabVIEW of the graphical programming language based on virtual instrument as the tool to develop the testing software. It realizes the functions such as the data acquisition, storage, analysis and display, single point wiring harness testing, all wiring harness testing, impedance testing, query and statistics, etc. We uses software instead of hardware so that functions can be added or cut down at random without adding any other hardware facilities.
