[Abstract]:With the rapid development of computer technology, the combination of computer technology and electronic measurement technology has formed an automatic test system, which has made a qualitative leap in electronic measurement technology.The automatic test system has more advantages than the traditional electronic measuring instruments in the aspects of test speed, efficiency, precision, reliability and the exchangeability of test data.Virtual electronic measuring instrument integration system is a set of automatic test system developed by Jilin University. With the modular design concept, various electronic measuring instruments can be integrated into a module card that can realize the corresponding measurement function.Then it is connected by custom bus technology to form a testing tool which can realize various electronic measurement functions.The main work of this paper is the research and design of the integrated system infrastructure of virtual electronic measuring instruments.First, study the existing bus technology, extract a bus technology suitable for the system; second, design the communication protocol between the system controller and various modular instruments; third,The design of USB2.0 system controller is used to realize the data communication between host computer and modularized instrument. The design of USB2.0 system controller includes hardware circuit design and firmware program development.The system driver is the "bridge" of communication between the host computer and the system controller, which encapsulates the function of the USB interface operation. The upper computer LabVIEW accesses the USB universal driver by calling the function in the DLL.Implement the operation of USB interface.Finally, the system test proves that the integrated system infrastructure of virtual electronic measurement instrument designed in this paper can realize the communication between the host computer software and the modular instrument, and achieve the design goal.
