Design of Human Biomedical Signal Simulator Based on the SOPC

With the improvement of people´s living standard, the demand of strengthening their health is increasing day by day. The emergence of multi-parameter monitor will always check whether the body´s normal physiological parameters. However, with the increase of biomedical monitors, Functional testing of biomedical monitor are gradually strengthened. This paper designs a multi-parameter, high-performance, low power portable instrumentation, biomedical signal simulator. The system uses SOPC technology will integrate in one CPU, and design digital logic and distinctive Signal conditioning circuit in order to achieve technical indicators and monitoring functions, and achieve a variable resistance and increase the self-checking system. The paper designs the detailed waveform circuit, signal conditioning circuit and biomedical signal detection circuit, finally the system simulates various biomedical signal waveforms and show the data output by the man-machine interface. The system can be accomplished conveniently and quickly by using Altera Quartus II, SOPC Builder and Nios II IDE software. In a word, hardware design is more flexible than before, and system upgrades more and more convenient.
