A Study on the Application of Virtual Instrument to the Sensor Technology’s Experiment

The characteristic of virtual instrument and its application to the sensor experiments are studied in this paper by using the design of multi-channel quality testing equipment based on LabVIEW.Compared with the quality of traditional measuring instruments,the system not only has the characteristics,such as more simple structure,low cost,convenient,and reliable and so on,but also gets better visual effect of the experiment,makes the principle more visualized and easy to command.At the same time teacher’s workload will be greatly reduced by adopting virtual instrument in the experiment of sensors,so it has good practical value.
