Introduction Instrumentation for a long time in scientific experiments occupy a very important role, is also the instrument of our physical education, physics experiment to carry out an important foundation. The development of puter technology and applications to the instrument in the field has brought profound changes, in particular the emergence of virtual machines and applications can be said to be a revolution in the field of equipment, but for a long time, whether they are in our physical education activities, Still dominated by traditional instruments, puters and measuring instruments are basically still in the isolated state, which will greatly affect our understanding oftheart equipment and hands, so learning some basic knowledge of the virtual instrument is quite necessary. The virtual instrument panel has a virtual personal puter equipment. It is mon personal puterbased simulation software function and control of hardware ponents. Operators through friendly graphical interface and graphical programming language to control the operation of equipment, plete testing by the volume of the collection, analysis, judge, show that the data generated and stored. Virtual machines have the following characteristics. 1） Virtual instruments to make full use of puter hardware and software resources to break through the traditional instruments in data processing, storage and expression, and other restrictions, have made traditional instruments unparalleled. 2） Software is the core of the virtual instrument. In general puter platform to configure the appropriate modular hardware, the next great deal of work is the preparation of the software. 3） Virtual instrument structure flexible, easy to upgrade, virtual instrument hardware structure is relatively fixed, and the software does have a great deal of flexibility to upgrade the operating system or software, virtual machines can be updated replacement. Virtual machines for its outstanding merits, have shown strong vitality, and the emergence of widely used test equipment will have a very profound impact. 2 .the position and apparatus operating principle With the pletion of a number of parameters of the equipment has been tested in the field of measuring a real problem with traditional instruments often very difficult to achieve. The most mon is by increasing the types of equipment to multiparameter measurements, but this only increased the cost of measurement, but also reduces the reliability. The use of virtual instrument design, can easily achieve a number of parameters of measurement, the instruments to test the temperature, force, pressure, displacement, mechanical vibration parameters 5, a total of 6channel, the channel testing with the exchange, At the same time can be measured one or more of the parameters. We use temperature, force, pressure, displacement, vibration sensor signal conditioning devices with the pletion of the acquisition and signal amplification。 Using virtual instrument multiparameter measurement Lv Dongmei Lv Xiang 1. Bijie Department of Physics Teachers College, Guizhou 2. Space Station Electrical and Mechanical Services Group, 3422, Zunyi of Guizhou [Abstract] The concept of virtual instruments and the advantages of virtual instrument with elaborate multiparameter measurement of the child design process. [Key words] virtual instruments。 multiparameter measurement. Key words: TAB24。 the use of data acquisition cards to plete A / D conversion by the puter to plete the final data analysis, to deal with. Hardware equipment is mainly responsible for signal conditioning and analogtodigital conversion, through the bus and PC puters to exchange data. Users to use the mouse or keyboard directly in the virtual panel on the operation can be easily pleted the parameters of the test, analysis, printing and other functions. 3. the instrument hardware design Virtual hardware equipment, including puter hardware and equipment hardware consists of two parts, of which only equipment needed is the hardware design. The The hardware equipment from the main sensors, signal the same token, data acquisition cards and four puter parts. To cover a larger range and meet certain measurement accuracy, the choice of different parameters measuring range of more than sensors. For example, force measurement in the range of 01KN, precision measuring % (FS), should be measured by the upper limit of the four sensors assistance to cover their range. NI signal conditioning devices selected panies ( Nationnal Instruments, National Instruments, is a virtual pr
