Noncontact sleep monitoring device based no ultrawide-band radar and noncontact sleep staging method based on ultrawide-band radar

Abstract

The invention provides a noncontact sleep monitoring device based no ultrawide-band radar and a noncontact sleep staging method based on ultrawide-band radar. The noncontact sleep monitoring device based no ultrawide-band radar comprises an ultrawide-band radar module, a data acquisition and transmission module, a power module, a data cable and an upper computer. The noncontact sleep staging method includes: using the noncontact sleep monitoring device to acquire radar echo data of a human body lying down and transmit the same to the upper computer; allowing the upper computer to perform DC component removal and Fourier transform on the radar echo data, and analyzing and distinguishing body movement states through frequency-domain waveform; subjecting the radar echo data to digital filtering and Fourier transform to extract sign characteristic parameters; staging the sleep states according to the analyzed and extracted body movement states and sign characteristic parameters. The noncontact sleep monitoring device based no ultrawide-band radar and the noncontact sleep staging method based on ultrawide-band radar can acquire body movement and sign information in noncontact and interference-free manner and can stage the sleep condition, and good comfort and convenience of use are provided.

Description

technical field [0001] The invention relates to the fields of sleep monitoring and sleep assessment, in particular to a non-contact sleep monitoring device and a sleep staging method based on ultra-wideband radar. Background technique [0002] In the prior art, the commonly used method in medicine is to use polysomnography, let the human body wear a chest breathing belt, abdominal breathing belt, and cooperate with electrocardiogram, electroencephalogram, myoelectricity and the method of blood oxygen concentration measurement to make a comprehensive diagnosis. Traditional testing and diagnosis methods need to use multiple testing methods at the same time, which is inconvenient to use in most occasions. In addition, a large number of electrodes need to be pasted on the human body, which is not used to people who try it at the beginning, but it will affect the sleep test results, and it is also inconvenient for multiple measurements over a long period of time. [0003] After ...

Problems solved by technology

Although the patent provides a radio wave echo signal analysis method and sleep breathing disorder detection, which is more convenient than traditional polysomnography, but the method of extracting information from the echo and the method of sleep staging are insufficiently described. In today's intelligent society, it still cannot meet the needs of users
