Embodiment Construction

[0039] Such as figure 1 As shown, a non-contact sleep monitoring device suitable for households includes transmitting and receiving antennas tan1, tan2, a non-contact bio-radar front end, and a DSP processor. The front end of the non-contact bio-radar is used to transmit narrow pulse signals to detect the breathing signal of the sleeper man in the sleep state, transmit the pulse sequence signal to the chest wall of the sleeper through the transmitting antenna tan1, and pick up the reflection back containing the sleeper's breathing information through the receiving antenna tan2 The wave signal is output to the DSP processor after relevant detection and variable delay processing. The DSP processor processes the breathing signal, and uses breathing pattern recognition algorithms (preprocessing, feature extraction, cluster analysis) to automatically recognize and control the breathing pattern.

[0040] Among them, the front end of the non-contact bioradar includes a narrow pulse shap...

Abstract

The invention discloses a household non-contact sleeping monitoring device and a household non-contact sleeping monitoring method. The device comprises a transmitting antenna, a receiving antenna, a non-contact biological radar front end and a DSP (Digital Signal Processor), wherein the non-contact biological radar front end is used for transmitting a pulse sequence signal to the chest wall of a sleeper in an oriented way through the transmitting antenna; the receiving antenna is used for picking up a reflected echoed signal including breathing information of the sleeper; the reflected echoed signal is output to the DSP through relevant detection and variable delay processing; and the DSP is used for performing steps such as preprocessing, breathing characteristic vector extraction and cluster analysis on a breathing signal of the sleeper to realize automatic recognition and control of a breathing mode. According to the device and the method, a sound and light alarm can be made on the premise of not influencing normal sleeping of a human body, so that the sleeper who stops breathing temporarily is forced to wake up.

Description

Technical field [0001] The invention relates to a breathing signal monitoring technology, in particular to a non-contact sleep monitoring device and method suitable for families. Background technique [0002] In recent years, with the increasing progress of modern medicine, sleep medicine has gradually established and developed as an important part of modern medicine. The research on sleep breathing is directly related to the research on sleep diseases, so sleep breathing has become a more concerned issue in sleep medicine, especially sleep apnea hypopnea syndrome (Sleep Hypopnea Syn-drome, SAHS) has been widely Pay attention. [0003] Sleep apnea syndrome is a disease that seriously endangers people’s health and lives. Epidemiological data in the United States show that the main cause of sleep apnea syndrome is adult men over 40 years old, and the population incidence rate is as high as 1%. -4%, there is no relevant epidemiological data in my country. Sleep apnea syndrome refers...
