Embodiment Construction

[0037] see figure 1 , which is a flow chart of the heart rate and respiration detection method in the embodiment of the present invention. The heart rate breathing detection method comprises the following steps:

[0038] Step S1: Obtain the heart rate and respiration signal collected by the heart rate and respiration detection device; wherein, the heart rate and respiration detection device includes an elastic cloth for fixing on an external bearing structure carrying the human body, and an acceleration sensor, and the acceleration sensor is set on the cloth.

[0039] In one embodiment, the cloth body is preferably a cloth with certain elasticity, such as canvas, by setting the acceleration sensor on the cloth body, and then setting the cloth body under a load-bearing structure that carries the human body, such as under a nylon bed or under a canvas chair, Furthermore, the elastic cloth body can prevent the acceleration sensor from popping off from the carrying structure whe...

Abstract

The invention relates to a heart-rate and breathing detection method and system. The heart-rate and breathing detection method includes the steps that heart-rate and breathing signals collected by a heart-rate and breathing detection device are obtained, wherein the heart-rate and breathing detection device comprises a cloth body which is used for being fixed on a bearing structure for bearing thehuman body and has the elasticity and an acceleration sensor, and the acceleration sensor is arranged on the cloth body; the heart-rate and breathing signals are subjected to Kalman filtering and band-pass Butterworth filter processing, and heart-rate and breathing signals after denoising are obtained; whether the heart-rate and breathing signals after denoising are effective or not is judged, ifthe heart-rate and breathing signals after denoising are inefficient, heart-rate and breathing signals collected by the detection device continue to be obtained, and if the heart-rate and breathing signals after denoising are effective, the effective heart-rate and breathing signals are processed by dividing the effective heart-rate and breathing signals into two parts, one part is used for obtaining heart-rate information, and the other part is used for obtaining breathing information. According to the heart-rate and breathing detection method and system, a clumsy and heavy wearing device isnot required to be worn, harm such as radiation to the human body can also be avoided, and using is convenient and fast.

Description

technical field [0001] The present invention relates to a heart rate and respiration detection method and system, in particular to a non-contact heart rate and respiration detection method and system. Background technique [0002] Heart rate and respiration are the most important physiological parameters of the human body. There are two main ways to detect heart rate and respiration: [0003] (1) The wearable device is worn on the human body to measure and display the current heart rate and respiration of the human body through direct contact with the human body. However, the existing wearable devices are usually heavy, and when the human body wears the wearable device, it feels clumsy and uncomfortable. [0004] (2) The radar-based physiological motion sensor detects, generates electromagnetic radiation from the radiation source through a non-contact human body, and then receives the signal of each frame fed back from the human body, processes the signal, and then obtains ...
