Health monitoring device and method based on millimeter-wave radar

Abstract

The invention relates to a health monitoring device and method based on millimeter-wave radar. The health monitoring method comprises the following steps: a signal acquisition module acquires information of a to-be-detected human body, and obtains a modulation pulse phase change signal generated by the distance of the human body according to the information of the human body; a signal processing module adopts a wavelet transformation method to separate and reconstruct a respiration signal, a heartbeat signal and a body movement signal according to the modulation pulse phase change signal so asto determine health indexes of the human body, and compares and analyzes the health indexes with preset values so as to determine prompt information, wherein the health indexes comprise a cardiopulmonary resonance index, heart rate variability and respiratory variability; and an index prompting module displays prompt information. The device can provide completely interference-free, contact-free and penetrable health monitoring, and is particularly suitable for health monitoring in environments such as beds, toilets and vehicles.

Description

technical field [0001] The invention belongs to the technical field of health monitoring equipment, and in particular relates to a health monitoring device and method based on millimeter wave radar. Background technique [0002] The monitoring of human physiological parameters is generally required in families, hospitals, and nursing homes. Most of the monitoring equipment currently used is suitable for measuring electrodes, which are directly in contact with the skin to measure physiological parameters such as ECG and blood pressure, and directly display them on the screen. There are two issues to consider here. First of all, the electrodes and wiring lead to the inconvenience of the subjects, especially chronic disease patients and the elderly for long-term monitoring. For newborns or burn patients, it is often not feasible or unpopular to place electrodes on the patient. Second, the measured physiological parameters are directly displayed without further analysis and in...
