Multi-channel integrated non-contact vital sign monitoring system

Abstract

The invention discloses a multi-channel integrated non-contact vital sign monitoring system. The system comprises a vision part, an ultra-wideband radar part and an infrared temperature measurement part. Through wireless monitoring of various vital signs (including heart rate, breath and body temperature) of multiple targets, vital sign information of each target is displayed in real time, real-time monitoring function of the targets is achieved, and an alarm will be given out in time when the target vital signs are abnormal.

Description

technical field [0001] The invention belongs to the field of medical technology / electronic information technology based on multi-sensor fusion monitoring, and in particular relates to a non-contact vital sign monitoring system. Background technique [0002] In recent years, the state has introduced a series of policies to support the development of medical and health care. The development of intelligent monitoring and smart medical care has also become an important trend of development. With the in-depth advancement of smart medical care, the need to obtain as much vital sign information as possible in real time and comprehensively analyze health status is becoming more and more urgent. [0003] Traditional vital sign monitoring methods are mainly contact-based, usually using sensors such as pressure, electricity, and magnetic field, and calculating information such as human respiration rate and heart rate by measuring changes in physical quantities such as capacitance and ...

Problems solved by technology

Due to the limitations of contact, this method will make it inconvenient for the subject to move, and the deployment is cumbersome, it is difficult to meet the real-time needs, and for some special groups, such as infants, burn patients and other groups, or people with In the rescue of obstacles, the target cannot be effectively monitored, which limits its scope of use

[0004] Ultra-WideBand (UWB) radar has the characteristics of low power consumption and high resolution, and provides a non-contact, one-meter monitoring method for multiple people, and can perform non-contact monitoring of multi-target heart rate and breathing vital signs , but limited by its low target recognition, susceptible to interference and other shortcomings, it is difficult to be practically applied; the infrared imager can accurately measure the body temperature information of the detected target, but it also has the problem of low target recognition; the binocular camera has many Good target recognition, but no vital signs
