Study On A Non-contact Vital Sign Monitoring System

Vital signs include heart rate, respiration, blood pressure, body temperature, such as index, the traditional signs monitoring means for medical institutions to master more, with the development of mobile portable devices, wearable equipment as well as people living standard rise, people pay more attention to their own health than ever before. But the traditional monitoring devices exist limitations such as :electrodes in contact with the skin contact signs, limited by cable, intervention monitoring may cause physiological parameters change. In the case of special scenarios which cannot contact monitoring, contact monitoring equipment has great limitations. Non-contact vital signs monitoring equipment can solve such problems.This paper puts forward a kind of non-contact vital signs monitoring system, the system sets sedentary breathing, heart rate monitoring, environmental monitoring, and other functions into an organic whole, can provide reference for household intelligent robot. In this paper, research work is focused on:(1) for signs and non-contact detection technology research;(2) for the design of the radar monitoring system;(3) real-time heart rate respiration signal monitoring system design;(4) based on embedded vital signs of biological radar monitoring system implementation.In this paper, research work are the main innovation points:(1) design the starting point for practical application. Considered the system miniaturization, lightweight in order to improve the portability, sufficient to reduce the power consumption of the system, extend battery life, etc., finally designed a vital signs monitoring products.(2) based on office and family environment, to achieve the real-time signs of signal acquisition, filtering, amplifying, separation and signal recognition, and can accurately response is obtained through the human body signs transformation of heart rate and respiratory parameters.(3) the laboratory’s algorithm, PC environment improvement and transplanted to the embedded platform, implement the practical application of the algorithm, the transition, the real reason algorithm theory help to solve the practical problems;(4) the exploration and implements the sedentary monitoring, set up a sedentary relatives and friends to remind and reward mechanism, help people to a certain extent, reduce the sedentary, to overcome the sedentary.
