Auto-testing and control system for heat exchange experiment with wind tunnel based on virtual instruments

A Auto-testing and control system is made up by applying virtual instruments technology on heat exchange experiment with wind tunnel. This distributed control system combines computer technology and auto-testing technology. How to build the software and hardware of auto-testing and control system is introduced particularly, and hardware is substituted by software in some extents of this system. The way of data analysis by computer is given, the accuracy and stability of this system is analyzed at the same time. The application of virtual instrument technology on fluid machinery is explored in this paper.
