Design and Application of a Measuring and Diagnosing System Based on Networked Virtual Instrument

With the rapid development of virtual instrument technology and network technology, the networked virtual instruments appear great potential in remote measuring and diagnosing field. This paper first presents a measuring and diagnosing system for complicated electric equipments based on PXI/VXI networked virtual instruments, then analyze the architecture of the network and the hardware, software configurations. Currently, the system has been successfully implemented in a large, complicated electric equipment for measuring and diagnosing, and achieved good results.
