The Sensor Virtual Experiment And Virtual Laboratory Based On The Virtual Instrument

The Virtual Experiment and Virtual Laboratory appear with the development of computer technique and Virtual Instrument technique. As a new experiment method, the Virtual Experiment is out of the limits of time and space, and it has superiority that the Traditional Experiment doesn't have. The sensor which plays an important role is the initial link of measurement and control system. The sensor's category is numerous and the knowledge involved is wide. We can understand sensor from the work principle, the structure and the constitution, the adjusting circuit and the characteristic analysis. The thesis studies the Sensor Virtual Experiment and Virtual Laboratory with Virtual Instrument technique. Firstly, using LabVIEW, the sensor virtual experiment can collect and analyze data automatically through the serial communication bus and PCI bus data acquisition equipments and create the experiment report. With the development of network technique, the Network Virtual Laboratory which has great capacity to contain information whose form is various becomes an important form and the information can be shared through internet. Secondly, the thesis studies the Sensor Network Virtual Laboratory. When Virtual Instrument is published on network, the Virtual Laboratory is created on network. Thirdly, the thesis studies several different methods to publish the Virtual laboratory on network with Virtual Instrument tenique, such as publishing the VI on network, using the DataSocket Server, ActiveX technique and the dynamic web page based on the Virtual Instrument etc. In addition, several other methods are introduced to establish Virtual Laboratory, such as Flash, Video etc. In the end, the thesis gives the summary to the study and outlook to the development direction of the sensor Virtual Laboratory in the future.
