| Abstract: | AIM To construct the mathematical model between the non contact detecting system for life parameters and piezoresistive acceleration sensor. METHODS Mathematic model for the piezoresistive acceleration sensor and the return wave of self dithering of the detecting system was constructed by using the principle of the senor and detecting sys tem, and the mathematic model was simulated and analyzed by computer. RESULTS The amplitude of the return wave of self dithering of the detecting system could be attenuated 19.7 times by means of adaptive signal processing with this mathematic model. CONCLUSION The results simulated and analyzed by the computer match with the analysis in theory for the mathematic model, and this model can provide theoretical instruction on restraining the self dithering of the the non contact detecting system for life parameters. |
