Design And Realization Of Sensor Experiment Teaching System Based On Virtual Instrument

Virtual instrument refers to the computer through the good performance of modular hardware and flexible and efficient software combined to complete various tests,measurement and automation applications.Virtual experiment teaching is a new type of experimental teaching mode which is developed with the development of information technology.It can solve the problems existing in traditional experimental teaching effectively.Based on the experimental teaching center of electronic information technology experimental teaching environment for example,solve the following problems in the experimental teaching of experimental equipment such as:(1)the number and types of sets can not meet the demand;(2)the restriction of time,space,personnel;(3)experimental equipment renewal slow,cannot follow the advanced technology.In order to solve the above problems in the traditional experiment teaching,improve the efficiency of teaching and scientific research,electronic information technology based virtual simulation experimental teaching center in the experimental center of the existing Lab VIEW software,virtual instrument technology and the use of national instruments,designed a sensor based on Virtual Instrument experimental teaching system of virtual experiment platform my school.This thesis describes the experimental principle of the performance measurement bridge circuit strain gages,and thus the design of the main function of this experimental system,respectively,to design the hardware and software architecture of the system from the two aspects of the simulation model and the actual model.The simulation model is only performed by a computer equipped with LabVIEW software.On the front panel of the experiment system,users can log in,select the experiment,input data and read,and generate the experiment report.The actual mode consists of a slave computer connected with the data acquisition hardware and an upper computer operated by the user.The slave computer is responsible for data acquisition and processing,and the user sends and obtains the experimental data using the host computer.
