Problems solved by technology

[0003] However, when the common heart rate method is detected, the extraction and calculation method of the heart rate is relatively simple, which leads to insufficient accuracy. At the same time, in common systems, when the system power supply voltage is unstable, the system cannot perform detection, which leads to insufficient service life of the system. long

Abstract

The invention discloses a BCG-based non-contact heart rate monitoring method and system. According to the invention, a BCG acquisition module is fixedly installed outside a control module; the output end of the control module is connected with the input end of the BCG acquisition module; the output end of the BCG acquisition module is connected with the input end of the control module; a vibration sensor is fixedly installed at the input end of the BCG acquisition module; the output end of a processor module is connected with the input end of a data recording module; the output end of a data analysis module is connected with the input end of a data early-warning module; the output end of the data early-warning module is connected with the input end of a receiving terminal; the output end of the receiving terminal is connected with the input end of a display terminal; and a lifting wavelet module and a heart rate extraction module are arranged in the BCG acquisition module, so data acquired by the vibration sensor and the BCG acquisition module can be precisely analyzed and processed, and the stability of the data is improved.

Description

technical field [0001] The invention belongs to the technical field of heart rate detection, in particular to a BCG-based non-contact heart rate monitoring method and system. Background technique [0002] Due to the constraints of sensors, electrode sheets, wires, battery life and other factors, wearable vital signs monitoring technology seriously affects the user experience and comfort, and brings great difficulties to practical applications. The non-contact vital sign monitoring technology is a promising vital sign monitoring technology because it does not have any impact on the user and completes the collection of vital signs without feeling. For example, heart rate monitoring currently mainly uses manual observation of chest rise and fall to judge heart rate, which is time-consuming and labor-intensive and prone to errors. Or use wearable thermal resistance lead heart rate monitoring or abdominal pressure belt heart rate monitoring, which has high accuracy. [0003] Ho...
