System of human basic parameters signal acquisition

With the application of large-scale integrated circuits, large amounts of data acquisition and statistical analysis become more and more simple, the collection of human body basic physiological parameters can be realized in the school laboratory. Firstly, obtain the corresponding signal respectively by hardware circuit, then sent to the virtual instrument for realtime display. Virtual instrument is powerful, realistic appearance and flexible interface, so it can display various forms of parameters (R.WANG et al 2007, M.Kostic 1998), also can process the data acquisition. As a programming language, the completed virtual instrument can be generated as an application, dynamic link library or installation package, it can still run divorced from the LabVIEW environment.
