Abstract: As a kind of computer technology applied in automation industry, virtual instrument (vi) technology is a new direction of instrument designing. Based on the analysis of micro-propeller current meter, a new current velocity measuring system of hydraulic river model is developed. The system is designed with VI technology, merging some computer resources and the related hardware together. The paper focuses on the total architecture of the system virtual instrument, design pattern, data structure and hardware driving technology. IN contrast to the method of traditional text programming, the graphic programming of LabVIEW to design VI is clearer in logic and easier to simplify the system developing process. It is also more efficient to enhance the automatic level of the other river model instruments.
