Real-time heart sound signal diagnosis system and diagnosis method thereof

The invention discloses a real-time heart sound diagnosis system and a diagnosis method thereof. The real-time heart sound diagnosis method comprises the following steps: receiving real-time heart sound data and performing framing processing; reading the heart sound data frame by frame, performing noise reduction and filtering processing, and then performing caching; extracting heart sound envelopes of the cached heart sound data subjected to noise reduction and filtering processing through a first algorithm, and screening a heart sound envelope conforming to physiological characteristics; extracting a characteristic parameter set of the heart sound envelope conforming to the physiological characteristics; and inputting the characteristic parameter set of the heart sound envelope as an input node into a diagnosis model to obtain a diagnosis result. The real-time heart sound diagnosis system and the diagnosis method thereof can be used to obtain accurate real-time heart sound diagnosisresults and provide more
