Physiological parameter monitoring sleep assisting method based on optical fiber sensing

Abstract

The invention belongs to the related fields of sensor technology, wearable equipment and the like, and discloses a physiological parameter monitoring sleep assisting method based on optical fiber sensing, which comprises the following steps of: arranging a physiological signal acquisition front end at a rest position of a user; the physiological signal acquisition front end is used for acquiring a BCG signal of a user; the BCG signal is preprocessed; and monitoring and distinguishing the preprocessed BCG signal through an algorithm model. Based on the principle that weak physiological movement can cause optical fiber micro-bending deformation to further cause light intensity change, a physiological parameter monitoring system based on optical fiber sensing and through monitoring data, the system adaptively detects fine light intensity change through an optical detector to obtain ballistocardiogram signals, and the ballistocardiogram signals are transmitted to the optical fiber sensing system. A signal processing algorithm is used for obtaining information such as heart rate, respiratory rate and body movement. Experiments show that the developed system can measure physiological parameters in a non-inductive manner in a zero-load state, and has a wide application prospect in the field of health and medical treatment.

Description

technical field [0001] The invention belongs to the related fields of sensor technology, wearable equipment, etc., and in particular relates to a sleep aid method for monitoring physiological parameters based on optical fiber sensing. Background technique [0002] One-third of a person's life is spent in sleep. Sleep is a need of life, and people cannot live without sleep. The quality of sleep plays a vital role in human health. In the current fast-paced era, sleep diseases such as insomnia, lethargy, night terrors, and nightmares are becoming more and more serious. There are often sleep monitoring wristbands and watches on the market because they need to be worn and touch the skin during measurement. Therefore, they have poor comfort and poor individual compliance, which makes many users unable to adapt. [0003] The monitoring of cardiopulmonary function is an important part of health monitoring, and the real-time measurement of heart rate and respiration rate is the prem...
