Design of Remote Virtual Signal Analyzing Instrument Based on LabVIEW

Virtual signal analyzing instrument was developed based on LabVIEW and was published on the Web server with the Remote Panels technology of LabVIEW.A Web-based virtual instrument test network was built.Network communication of B/S model was real-ized.Users may directly operate the virtual instrument of server through the browser of client.The remote measurement and analysis of signal,data storage,and waveform display was realized.The purpose of sharing resources was reached.The system was tested in practical task.The test shows that the system completes the networked control of instrument and remote measurement of object.The system has the characteristic of fully functions and easily operation.The system can proceed not only the signal display and analysis in real-time,but also the analysis and processing of gathering result in the memory under the off-line condition.It shows the advantages of virtual instru-ment technology and networked measurement and control technology.
