Abstract

The embodiment of the invention discloses a signal processing method and a signal processing device. The signal processing method comprises the following steps: acquiring heart shock signal data and heart vibration signal data of a user within a period of time, wherein the heart shock signal data and the heart vibration signal data are synchronized in time, acquiring linked feature parameters of the heart shock signal data and the heart vibration signal data, wherein the linked feature parameters are used for expressing the correlation features of the heart shock signal data and the heart vibration signal data in time / frequency domain, and outputting the linked feature parameters. With the adoption of the embodiment provided by the invention, more feature parameters can be obtained, more information is provided for preventing cardiovascular diseases, and heart shock signals and heart vibration signals are effectively utilized.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a signal processing method and device. Background technique [0002] With the development of computer technology, a large number of products have emerged in the smart wearable and non-wearable markets, such as smart bracelets and smart watches, which are common products related to health detection in people's daily life. In addition, there are sleep monitoring belts on the bed, smart mattresses and other non-wearable smart devices that use acceleration sensors to detect human physiological information. The core physiological information obtained by such non-wearable smart devices is the Ballistocardiogram (BCG) signal, which is mainly used to obtain the parameter of real-time average heart rate. The BCG signal mainly describes the recoil effect of the blood on the blood vessel when the heart ejects the arterial blood in the heart to the aortic arch during the contracti...
