Study On Network Virtual Instruments Applied In Handling Qualities Analysis

Virtual Instruments is one of new technologies which is evolving with the development of computer technology. Utilizing the powerful computing capability of computer and flexible software techniques, it overcomes the limitations of traditional instruments and implements different kinds of instruments architectures demanded based on limited hardware. In our thesis, firstly, we introduce the concepts of measurement and control system, the concepts of network measurement and control system. Secondly we introduce the concepts, characteristics, and development of virtual instrument, we introduce the framework and common development software of VI and then detailedly discuss the data transmitting technology and data transmitting mode. At last, we implement a network measurement and control system for a plane experiment.The main part of this thesis is the design of a network measurement and control system of a plane experiment. The system implement the functions that remote startup computer, remote control, data acquisition, data storage and data remote transmitting. What finished in this paper has been successfully applied in data acquisition and process system operated on the iron bird integrated test equipment in flying control lab specially set up for some third generation military training plane.
