【Abstract】 Thelw are three basic requirements in the development of virtual instrument: opening industrial standard,interchangeability and interoperateability.Based on the three re- quirements,this paper indicates the problems should be solved in the application of virtual instrument,and presents a solving method of using fire wire (IEEE-1394)which will be widely used in external device wire in the virtual instrument,and the development needed to do.更多还原
