非接触式生理参数检测系统的设计与实现

Design and Implementation of a Non-contact Physiological Parameter Detection System

体温、心率、呼吸率和睡眠质量等是人体常见的重要生理参数,能够反映被测者的生理状况。传统的生理参数监测主要采用接触式电极、传感器等与人体直接接触监测人体的生理参数,在检测时会给被测者带来行动不便、操作不便、心理负担等问题。通过设计一款非接触式生理参数监测系统,改进传统监测系统存在的不足。采用毫米波雷达来检测人体的心率、呼吸率、体温和睡眠质量等生理参数,以及红外测温的方法检测人体的体温,使用STM32微处理器作为主控制器,实现人体常见生理参数的非接触式实时监测和显示,对生理参数的异常进行及时报警提示,呵护被测者的健康。

Body temperature,heart rate,respiratory rate and sleep quality are common and important physiological parameters of the human body,which can reflect the physiological status of the subjects.The traditional physiological parameters monitoring mainly uses contact electrodes,sensors and other direct contact with the human body to monitor the physiological parameters of the human body,which will bring inconvenience to the subjects,inconvenient operation,psychological burden and other problems.Through the design of a non-contact physiological parameter monitoring system,the shortcomings of the traditional monitoring system are improved.The millimeter wave radar is used to detect the physiological parameters such as heart rate,respiratory rate,body temperature and sleep quality,and the infrared temperature measurement method is used to detect the body temperature.STM32 microprocessor is used as the main controller to realize the non-contact real-time monitoring and display of the common physiological parameters,alarm and prompt the abnormal physiological parameters in time,and protect the health of the subjects.
