The development of distributed data acquisition system based on virtual instrumentation

The distributed data acquisition system is exploited to build a virtual laboratory in the network based on virtual instrumentation.In the laboratory,operating the system or logging on the laboratory server to control the programmes and data acquisition devices is available out of the limitation of time or space.Variable sensors with their corresponding signal conditioning circuits,and peripheral interface circuit make up the different acquisition modules.LabVIEW is made use of programming for not only data acquisition,analysis and calculation,but also dealing with the results.
