[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, and 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 present invention provides a sleep monitoring method, device and radar system based on frequency-modulated continuous-wave millimeter-wave radar. The second reflected signal in space. Mixing the first reflected signal and the second reflected signal with the local oscillator signal to obtain the first mixed frequency signal and the second mixed frequency signal; wherein the local oscillator signal is one generated by the frequency-modulated continuous wave millimeter-wave radar A signal with the same frequency as the transmitted signal at all times. According to the first mixed frequency signal and the second mixed frequency signal, the breathing frequency, heartbeat frequency and turning information of the target person are acquired. The invention extracts the detection signal by mixing the transmission signal and the reception signal, the circuit design is simple, the hardware consumes less resources, 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 ...
