Three way catalyst( TWC) is a device used in automotive exhaust system. In view of the problem that the force value and dis-place of TWC need monitoring before it is to be used, this paper presents a design project of using PCI-6221 multi-function data ac-quisition card and LabVIEW to establish a virtual instrument system, and gives the design steps, which realizes the detection and judg-ment on the device and uses the characteristics of the computer to carry out data processing and storage. After the application of the sys-tem, its acquisition precision and detection accuracy with a good practical value have a high level,.
