Computer based virtual instrument technology developed practical ability of undergraduates

On information times with the scale expansion situation in university, in order to develop undergraduates' practical ability and meet needs of talent for social development, the teacher should explore new ideas for practical teaching. This work inspires undergraduates to design their own comprehensive experiment by using the advantages of virtual instrument technology. Virtual instrument is a demand for the organization in accordance with instrument data acquisition system. It is a computer instrumentation systems with the general-purpose computer as the core hardware platform, designed by the user who defined functions, with a virtual panel, the test functions was realized by test software. This method optimizes practical teaching, develop the innovation ability and shape the quality of modern engineering of undergraduates.
