Abstract

The invention discloses a fiber interference technology-based sleep health monitoring system and relates to the technical field of intelligent health monitoring. The fiber interference technology-based sleep health monitoring system is characterized by comprising a flexible structure in contact with human body, a narrow-linewidth semiconductor laser device, a fiber interference system and a signalmodulator, wherein the narrow-linewidth semiconductor laser device, the fiber interference system and the signal modulator are sequentially connected, and the fiber interference system is connected with the flexible structure; the fiber interference system is composed of a 2*2 coupler, a 3*3 coupler, two optical fibers, two reflectors and three photoelectric detectors and is connected in a Michelson mode or a Mach-Zehnder mode. The fiber interference technology-based sleep health monitoring system acquires external disturbance information by collecting and analyzing optical signals from threedifferent phases, analyzes and processes the three acquired optical signals through the signal modulator to acquire information during sleep of a user such as pressure, breath and heartbeat. The fiber interference technology-based sleep health monitoring system has the advantages of being high in sensitivity, resistant to electromagnetic interference, diversified in data acquisition and high in practicality.

Description

technical field [0001] The invention relates to the technical field of intelligent health monitoring, in particular to a sleep health monitoring system based on optical fiber sensing technology. Background technique [0002] The emergence of wearable smart health monitoring devices has provided human beings with various devices for real-time monitoring of health status at any time. These wearable monitoring devices are implemented in the form of watches, belts, helmets, insoles, and even anklets. But in actual use, wearing a device on the body is always inconvenient. Human beings spend about one-third of their time in a sleeping state, lying on mattresses. If a health monitoring device can be installed on the mattress, it is possible to monitor human health without wearing a monitoring instrument. Health monitoring on the bed can also monitor people's sleep conditions, understand the individual's sleep conditions, and prevent the elderly or patients from breathing poorly or...
