Abstract

The invention discloses a wrist watch type multi-parameter biosensor and relates to a self-adaptive detection method for physiological parameters and a multi-parameter intelligent monitoring wrist watch by the adoption of the method. The method comprises the steps that (1) human physiological parameter signals are collected; (2) the human physiological parameter signals are subjected to self-adaptive wavelet decomposition, and feature predictors and updaters are selected point by point in the decomposition process; (3) waveform analysis is conducted, interference signals in the decomposed signals are eliminated, and human physiological parameter signals without interference are obtained. The monitoring wrist watch comprises a base body, wherein the base body is provided with a central processing unit, a physiological parameter sensor used for collecting the human physiological parameter signals and various other sensors. The central processing unit processes data by the adoption of a self-adaptive wavelet decomposition method to obtain the human physiological parameter signals without interference. The wrist watch type multi-parameter biosensor effectively solves the problem of instability caused by large contact resistance generated when a daily wearing mode is adopted. The wrist watch type multi-parameter biosensor is convenient to use and can collect various human physiological signals, movement signals, environment signals and the like in real time.

Description

technical field [0001] The invention relates to an adaptive detection method of physiological signals, and also relates to a multi-parameter intelligent monitoring watch adopting the method, which is mainly used for detecting human physiological parameters. Background technique [0002] With the improvement of living standards and health awareness, people hope to know their physical conditions at any time, so wearable biosensing systems emerge as the times require, but the wearable biosensing systems in the prior art are often clumsy and bulky. , needs special binding belt to be fixed, has influenced the daily life of the user, also affects the social interaction of attractive in appearance and the user. For the convenience and aesthetics of use, sensors (sensing devices) capable of collecting various required human physiological parameters / signals are placed on watch-shaped wearable sensing devices to form a sensor that can collect various human physiological parameters / sig...
