Abstract

This paper discusses the virtual instrument based on PXI bus and automated test system implementations,using a standard data acquisition card,DMM cards,analog input and output(AIO) cards and specially designed signal conditioning circuit and automatic test systems and engine control resources composed of the test system's hardware system. In this paper,automatic test system software development using virtual instrument software platform,the most popular LabVIEW development,LabVIEW software development is characterized by simple structure,easy to use,widely used by engineers in various industries. As the entire engine electronic control unit of a lot of test items,and the need for multiple products in parallel tests,so this issue also selected the TestStand as test executive management software. The application shows that the test system is stable and the test results are credible.
