A human body balance signals measuring system and the method of analysis thereof that has a measuring device, a filter amplifier, an A/D convertor (analog to digital convertor), a signal receiving module, and a data analyze module. The measuring device is linked with the filter amplifier. The filter amplifier can detect and collect the voltage signals caused by pressure change and then filter and amplify the signals. The signals are send to the A/D convertor to convert the analog circuit signals into digital signals for the receiving module to use these voltage change values for human body center of gravity offset evaluation to obtain the COP (center of pressure) offset and COP offset velocity. The data analyze module uses the measured body center of gravity offset for MSE (multiscale entropy) to quantitative the dynamic of human body center of gravity and verify the accuracy of this measuring system.一種人體平衡訊號量測系統及其分析方法,該人體平衡訊號量測系統係包括了一量測感測器、一濾波放大器、一A/D轉換器、一訊號接收模組及一數據分析模組,其中該量測感測器係與濾波放大器相介接,而該量測感測器可將壓力變化後的電壓訊號擷取出來,並經由濾波放大器進行訊號濾波及訊號放大,而後再藉由A/D轉換器,將類比的電路訊號轉換成數位訊號,並輸入訊號接收模組中,以此電壓變化值差來做人體重心偏移的分析,以求得COP位置偏移及COP偏移速度,並再由數據分析模組將所量測之人體重心偏移量的多尺度熵值,用於量化人體重心偏移量的動態特性,並以此驗證本量測系統的準確性。1...量測感測器11...重量感測器12...訊號轉換電路2...濾波放大器21...濾波電路22...放大電路3...A/D轉換器4...訊號接收模組5...數據分析模組
