Virtual System Of Monitoring And Analysis Physiological Signal Based On DSP

In recent years, along with the emergence of virtual instrument, the design and production of instruments have been changing. Based on Virtual Instrument Technology biomedical equipment has begun to appear. National Instruments Developed a Virtual Instrument language Lab-VIEW, it has abundant functions .Using I/O instrument realize acquainting and testing of signals, using powerful software realize calculating and analyzing and disposing of data, using the displayer to simulate the tradition control panel, in order to realize all kinds of testing functions through computer.Through the development of modern medical equipment trend analysis, combined with the virtual instrument technology and high-speed digital signal processing technology, we design a family of portable apply to real-time physiological signal monitoring device.TMS320VC5402 as the core of the system hardware modules, we introduced a system of hardware modules in all parts of the circuit design.Completed part of the DSP and PC part of the process of preparation. The signal achievement of the collection, display, as well as filtering, frequency conversion, such as auto-correlation algorithm.
