Abstract

The invention provides a sleep detection method and detection system based on body vibration signals. The system comprises a first amplifier, a filter, two second amplifiers, an analogue/digital signal converter, a signal interface and a server sequentially connected with a sensor, wherein the first amplifier is connected with the signal interface; one second amplifier is connected with the signal interface; and the server is used for analyzing the received signals and outputs the analysis result to information terminal equipment. The detection method comprises the following steps: collecting the body movement signals, and judging the sleep state according to the waveform amplitude variance of the body movement signals; converting the body vibration signals into electric signals by a piezoelectric sensor; extracting the breathing heart rate through the signal processing circuits such as an amplifying module; and evaluating the sleep quality by use of a sleep detection algorithm established based on movement amplitude, heart rate and breath. The test result indicates relatively high accuracy; and the method does not influence normal life of a user and is of great significance to non-contact sleep detection.

Description

technical field [0001] The invention relates to a sleep detection method and a detection system, in particular to a sleep detection method and a detection system based on body shock signals. Background technique [0002] People spend one-third of their time in sleep, and sleep plays an important role in assessing people's daily life conditions such as work pressure, fatigue and mental status. The medical understanding of the structure and process of sleep is accomplished by polysomnography. It can perform all-day monitoring, record various physiological indicators in time, and has real-time monitoring capabilities such as alarms. However, these devices are mainly concentrated in hospitals and research institutes, and their price of tens of millions restricts their popularity. In recent years, with the promotion of mobile applications, the development level of miniaturized and miniaturized detectors has been continuously improved. Tracking sleep quality has also become a fo...
