, remote monitoring and control equipment development. Graphical program programming is simple and intuitive, the development and high efficiency. With the continuous development of virtual instrumentation and graphical programming language, test and control areas will bee the most popular trends. The development direction of virtual instrument As a new instruments, the advantage of the virtual instruments is that userdefined functions and structure of the instrument, and easy to build, Conversion flexible it has been widely used in electronic measurement, acoustic analysis, fault diagnosis, aerospace, mechanical engineering, construction Engineering, railway transportation, biomedical, and many other aspects of teaching and research. With the development of puter hardware and software technology, munications technology and work technology, providing a vast world of the development of the virtual instrument, Chinese and foreign equipment sector is the large market. Monitoring equipment will be the efficient, highspeed, high precision and high reliability, and automation, intelligence and work direction. Open standards for data collection will put instrument on a standardized, universal, serial and modular way. The virtual instrument as a new teaching tool, has been slowly walked into the classroom and laboratory and is gradually changing the traditional mode of electronic technology teaching, which is the inevitable development of modern educational technology. In the construction of electric and electronic laboratory, some laboratory equipment have been conventional aging, some have technical backward, in the current school funds under the circumstances of less, If buy regular instrument and meter, it is difficult for the school to pay for it and it is not fit with the school’s situation. Moreover, with the test equipment digitalized, puterized trend, the traditional test instruments have the trend been gradually replaced. If the virtual instrument technology, puterbased, building integrated test platform, instead of conventional instruments , meters, not only to meet the needs of electrical and electronic experimental teaching, and will these puter course
