The paper introduces concepts and the general idea of Intelligent Virtual Controls based on Qin's Model,and advances a new instrumental mode ,that is Virtual Intelligent Twist and Rotate Speed Measurer ,which can be used in measuring the frequently used physical parameters in the rotate mechanical systems ,including twist ,rotate speed ,power and the axes-oriented force. The three-layered hiberarchy ,including the interface layer ,the testing and service layer and the hardware driving layer, is brought forward to design the Virtual Intelligent Twist and Rotate Speed Measurer ,which is a new creative method .In the hiberarchy, the lower layers provide the service and support to the upper ones, and the upper layers realize the functions of instruments with call-back of the lower ones .In the framework the three ones divide the work and cooperate well. An Virtual Instrument based on IVC-based-VI is successfully developed which is used in the twist and rotate speed measurement of the mechanical area.
