[0090] On the basis of the first embodiment of the present invention, in the second embodiment of the present invention, when the respiratory rate or heartbeat frequency of the target person is at a preset dangerous threshold, the network connection notification is associated with the frequency-modulated continuous-wave millimeter-wave radar user terminal, so that the associated user terminal can immediately know the abnormal situation of the target person, so as to prevent worse consequences. It can be understood that the network connection may be a wired network connection or a wireless network connection. It is not limited here. In some cases, the alarm module can also be set to immediately send out an alarm when it is judged that the monitored object has fallen, such as a buzzer, etc., to remind people in the same room to respond quickly.

Abstract

The invention provides a sleep monitoring method and device and a radar system based on a frequency modulated continuous wave millimeter wave radar. The method comprises the steps that a first reflection signal of target space under an unmanned state and a second reflection signal of the target space under a manned state are collected through the frequency modulated continuous wave millimeter waveradar; the frequencies of the first and second reflection signals are mixed with a local oscillating signal respectively to obtain a first frequency mixing signal and a second frequency mixing signal, wherein the local oscillating signal is a signal which has the same frequency as a transmission signal from a moment generated by the frequency modulated continuous wave millimeter wave radar. The respiratory frequency, heart beating frequency and body turning frequency of a target person are obtained according to the first and second frequency mixing signals. A detecting signal is extracted ina manner in which the frequencies of the transmission signal and a receiving signal are mixed, the circuit designing is simple, resources consumed by hardware is less, and the cost is saved.

Description

technical field [0001] The present invention relates to the technical field of information communication, in particular to a sleep monitoring method, device and radar system based on frequency modulation continuous wave millimeter wave radar. Background technique [0002] With the acceleration of the pace of life, people's life pressure is increasing, more and more people are in a sub-health state, and the number of people with insomnia is gradually increasing. At the same time, as the problem of aging society becomes increasingly prominent, the health problems of more and more empty nesters, especially chronic and sudden diseases such as cardiovascular and cerebrovascular diseases, have received widespread attention. Therefore, how to monitor human health indicators such as breathing and heartbeat in real time in an indoor environment, and how to determine whether a person has entered a deep sleep have become issues that need to be considered when paying attention to human ...
