摘要：
A dynamic physiological measuring system is disclosed. The dynamic physiological measuring system includes a sensor array, an amplifier unit, a triaxial accelerometer and an adaptive filter. The sensor array is disposed on an animal body portion and located on different positions. The sensor array can detect a dynamic physiological signal to generate a plurality of photoplethysmogram signals. The amplifier unit amplifies the photoplethysmogram signals to generate a plurality of amplified photoplethysmogram signals. The triaxial accelerometer generates a predetermined noise signal. Each of the real physiological signals has a main physiological signal and a real noise signal. The adaptive filter can remove the real noise signal by the predetermined noise signal. Therefore, the photoplethysmogram sensors with different positions can be combined with a noise reduction module to detect the dynamic physiological signal, so that the distortion produced by motion artifact can be compensated to extract the accurate signals.本發明提供一種動態生理量測系統,其包含感測陣列、放大單元、三軸加速度規及適應性濾波器。感測陣列設於動物體部位上且彼此位於相異之位置,並感測動態生理訊號以產生光體積描述訊號。放大單元放大光體積描述訊號並輸出光體積描述放大訊號。三軸加速度規用以產生預測雜訊。實際生理訊號具有主要生理訊號與實質雜訊,適應性濾波器可利用預測雜訊來消除實質雜訊。藉此,利用多個位於不同位置的光體積描述訊號感測器結合雜訊處理模組來同時量測動態生理訊號,可彌補運動雜訊所造成之失真並準確地得知生理狀況。100‧‧‧動態生理量測系統200‧‧‧生理訊號擷取模組300‧‧‧雜訊處理模組310‧‧‧三軸加速度規320‧‧‧適應性濾波器400‧‧‧訊號轉換模組410‧‧‧希爾伯特-黃轉換器420‧‧‧零相位數位濾波器
