Abstract

The invention discloses a physical sign non-contact intelligent monitoring system based on a millimeter-wave radar. A millimeter-wave radar front-end module transmits and receives a millimeter-wave radar signal, and the millimeter-wave radar front-end module is connected with a signal processing module; a signal processing module is connected with a communication interface module, analyzes the echo signals after sampling quantification to obtain vital sign data, including frequency parameters of respiration and heartbeat, of a tested person, and transmits a processed information result to an upper computer through the communication interface module; and the upper computer compares the received vital sign data with preset data, uploads the data and a comparison result to a background server, gives an alarm to the mobile terminal if the comparison result is abnormal, and automatically gives an alarm when the comparison result exceeds a preset maximum value. According to the invention, the real-time intelligent monitoring of vital signs of indoor old people is realized, including monitoring of breathing and heartbeat parameters, and real-time alarm is carried out in case of abnormality so as to prevent accidents.

Description

technical field

[0001] The invention belongs to the technical field of millimeter waves, and relates to a non-contact intelligent monitoring system for signs based on millimeter wave radar. Background technique

[0002] Radar is an object detection system that uses radio waves to determine the range, angle or speed of moving objects. The electromagnetic wave generated by the transmitter in the radar system captures the reflected wave of any measured target in the path of the transmitted signal through the transmitting antenna and the receiving antenna (separately or together as the previous one), and the receiver and processor complete the reception of the signal, analysis and processing.

[0003] Since the beginning of the 21st century, the rate of aging in my country has continued to increase, and the growth rate of aging is faster than the world average. The health problems of the elderly and their care issues have attracted more and more attention from the society. How...
