Embodiment Construction

[0035] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0036] For a better understanding of the present invention, it should be noted that in the present invention, body movement refers to the behavior state of a living body; respiration rate refers to the average number of respirations per minute; heart rate refers to the average number of heartbeats per minute.

[0037] The transient calm state refers to the detection of the presence of living things, but it is in the transition period to the steady state calm state.

[0038] The state of small movements refers to slight shaking movements such as turning around and raising hands.

[0039] The state of large movements refers to sudden standing, stretching, walking and other large shaking movements....

Abstract

The invention discloses a radar-based non-contact vital sign measuring system and method. The system comprises a radio frequency transceiver module, a signal collecting device, a signal processing device and a display device which are sequentially connected. The radio frequency transceiver module is used for transmitting a radar signal to a living body and receiving a radar echo signal reflected by the living body to form original echo data. The signal collecting device is used for collecting the original echo data and transmitting the original echo data to the signal processing device. The signal processing device is used for processing the received original echo data to form vital sign information of the living body. The display device is for displaying vital sign information of the living body. The system uses a microwave radar signal as a sensing medium to achieve non-contact measurement and improve the comfort of the living body. The respiratory rate, the heart rate and the body motion of the living body can be effectively extracted to achieve the purpose of real-time monitoring and early warning.

Description

technical field [0001] The invention relates to the fields of biomedical engineering and radar signal processing, in particular to a radar-based non-contact vital sign measurement system and method. Background technique [0002] At present, the traditional measurement method of vital signs (breathing / heart rate / body movement) is determined by physically contacting the living body with a pressure sensor and sensing the pressure changes caused by the abdominal ups and downs of the living body and the beating of the heart. This kind of contact-based measurement requires the living body to wear a specific sensor, which will make the measured living body feel uncomfortable and is not suitable for long-term measurement. The parameter measurement of the living body is realized through radar technology. The measured living body does not need to wear any sensors, and only needs to lie quietly within the monitoring range of the radar to realize non-contact and non-inductive measuremen...
