The Development Of Rapidly Recombination Measurement & Control Experimental System Based On VC++

Generally, the traditional measurement systems are constructed by special instruments and programs which have been designed.These traditional methods are with a single function and poor flexibility and expansibility. The development of Virtual Instrument Technology provides a new idea for mechanical engineering measurement. Software system of Virtual Instrument offers a serial of instrument panels which could be called. The relations between different modules would be completed by developer. In this way, measurement system could be made up flexibly. Moreover, for testing technicians, they hope that the constructing of measurement system is only related to the theory and technology of testing rather than the complicated job of software programming. This is also the requirement of the contemporary science research and the flexibility experiment system of college laboratory. Therefore, it has important practical and theoretical meaning to develop the rapidly recombination measurement & control experimental systems by modularization methods.In accordance with the requirement of the course experiment of Mechanical Engineering Measurement, the frame design of the hardware platform which is based on the mechanical platform with five degrees of freedom, the multifunction DAQ card, and several kinds of sensors & clamps is discussed in this paper . With inclusion of the requirement of recombination and flexibility ,the construction of the main modules of the software platform and the pivotal technology to constructing and realizing a measurement system without programming are analyzed.The paper concentrates on the implementation methods of the technologies of the designing of function control, the dynamic management & using of controls and the communication between controls based on the Visual C++ development environment and Measurement Studio integrated development software.Furthermore, the detail illustration of the concrete design are presented. Finally, the application of the rapidly recombination measurement & control system for some classic experiments has verified its feasibility and validity.
