Automated Test System Based on Virtual Instrument Technology for Embedded Computer System

Gong Yu-di

Abstract

An automated test system(ATS) based on PXI bus and LabVIEW for computer system embedded in the certain product was designed.In the ATS,the virtual instrument technology was employed and the software was developed based on LabVIEW 8.0.This system was composed of computer system embedded in the product,PXI-1042 chassis,PXI-8186 controller,PXI-7811R digital intelligent DAQ card,PXI-6224 DAQ card,PXI-6713 analog output card and VMIPMC-5565 reflective memory card and user interface based on virtual instrument technology.The system can simulate diversified excitation signal and sensor signal for testing.The ATS can test,inspect and analyze the embedded computer systems in the product automatically.With the use of ATS,the efficiency and reliability for product testing and inspecting are improved.
