[0053] The inventors of this application have discovered that most current ECG and heart sound signal acquisition devices collect heart sound signals using a single channel. Furthermore, the acquisition of ECG and heart sound signals is often intermittent, which results in the collected ECG and heart sound signals failing to reflect their corresponding relationship in real time, thereby reducing the accuracy of cardiac status analysis.

[0054] Through the above-mentioned embodiments, the present application can simultaneously collect ECG signals and heart sound signals by integrating the first electrode group, the second electrode group, and the heart sound sensor group on the same positioning belt. The present application can simultaneously collect multi-channel heart sound signals by providing a multi-channel heart sound sensor group.

[0060] According to an exemplary embodiment, signal conversion unit 172 is electrically connected to signal amplification unit 171 and converts the amplified ECG signal and heart sound signal into a first signal. The first signal may be a digital signal converted from analog signals obtained by amplifying the ECG signal and heart sound signal. Signal conversion unit 72 may be an analog-to-digital conversion chip or an analog-to-digital conversion component.

[0061] According to an exemplary embodiment, the microprocessor unit 173 is electrically connected to the signal conversion unit 172 to process the first signal to obtain a second signal. The second signal may be a digital signal obtained by encoding the digital signal with a proprietary protocol frame structure.
