Virtual instrument transformer automatic calibration device in the application and research

trol to achieve dynamic load the driver and removal, so that with system-level functions; data processing functions: the driver response to the data processing, according to measurement procedure, and of the whole and storage, but also determine the tolerance with automatic functions: Data management: the use of ADO technology to access various databases, to achieve test data, delete,[link widoczny dla zalogowanych], check, change and other data operations and maintenance. 1.3 External interface system which is PC virtual instrument that direct benefits. The traditional test equipment is a separate system, and different external devices to communicate difficult or impossible. But for PC virtual instrument, the PC,[link widoczny dla zalogowanych], with RS232 serial port, parallel port, USB interface, network interface, but also according to the demand expansion slot on the bus, so almost any device and Internet communications, makes the instrument with good open. External interface of the system with the usual serial and parallel port and network interface, and add a small LCD touch screen and dual monitors, no keyboard, you can single submission, with a scalable and suitable for field operation and so on. 2 virtual instrument of analysis and discussion can be seen from the program, the introduction of the virtual instrument technology transformer automatic calibration device, greatly improved the overall performance, making a relatively closed system into relatively independent open standard system, improve the system scalability, maintain and upgrade more convenient. From this development, we recognize the virtual instrument in the application of test equipment should be noted in some perspective. 2.1 The modular design of dedicated hardware is a feature of the virtual instrument virtual instruments with the PC hardware platform and common good scalability, so the hardware module will help build different application systems. Treated as a common link capacity, such as filtering,[link widoczny dla zalogowanych], amplification, shaping, A / D conversion can be considered part of common hardware such as programmable control module, built to a certain extent, a common dedicated hardware, thereby greatly increasing the speed of development instruments. 2.2 The underlying driver software design is personalized Another feature of the virtual instrument the operating system is now mostly Windows95/98 series, but as a non-real-time multitasking operating system, real-time support in certain issues; embedded operating system may be a good solution, but GM and development of resources is the biggest obstacle; free software Linux is perhaps instrumentation choice of software developers in the future. But at present, the VxD technology as the representative in Windovrs95/98 Windows device driver versions and even Windows2000Workstation is still a good solution, WDM technology is Window8 family of operating system driver development trend of development, can focus. In short, the underlying drive technology with the operating system platform of choice is closely related to the driver as long as the development is open and has a standard access interface, hardware access functions can be completed, the specific system can personalized design. 2.3 a multi-functional instrument is the basic characteristics of virtual instrument Pc machines take advantage of powerful features for data, images, sounds and other information processing, so that a single instrument as a functional combination of many instruments. In the underlying software, hardware support and the upper rich expression, the one instrument with the function of several instruments have become a basic feature of the virtual instrument. Different functions depends mainly on the software implementation, this must be noted in software development using object-oriented design concepts and work to strengthen the construction of library equipment to make the software truly become a virtual instrument of the soul. 3 Summary This paper introduces the development of virtual instrument background, the main transformer of the virtual instrument in the automatic calibration device application and the composition of virtual calibrator, and finally proposes the development of the virtual instrument should pay attention to the problem . Transformer transformer automatic automatic calibration device can measure and improve data management (equivalent to network applications including networking) capabilities, the introduction of virtual instruments in view, the functions become more powerful and perfect,[link widoczny dla zalogowanych], but also on the level of automated testing to a level, and as the popularity of computer technology, a wide range of virtual instruments that will continue to emerge. Contribute significantly to the level of our instruments. References: [1】 Tang reunification. Zhao Wei. Electrical Measurement and Instrument Technology Review and Prospect of Yuan [J】.
