摘要
针对人体在运动过程中体征参数多变、实时在线监测不易实现的问题,设计了一种无线运动传感器节点监测系统。系统采用STM32F103单片机作为主控芯片,利用ADS1292心电检测芯片、LMT70温度传感器以及MPU6050运动传感器,对人体在运动过程中的心率、体温和运动步数等参数进行采集。上位机采用LabVIEW搭建,通过无线传输,实现体征参数和运动步数的实时显示、超阈值报警与数据记录。经测试:系统工作稳定、测量准确度高,心率的相对误差为0%~1.67%,体温的相对误差为0%~4.11%,系统误差在5%以内。相较之传统的人体体征监测系统更加智能、更加便于对人体在运动状态下的体征参数和运动参数进行系统化集中化管理。
Aiming at the problem that life parameters are changeable and real-time on-line monitoring is not easy to realize during the movement of human body,a wireless motion sensor node monitoring system is designed.The system uses STM32 single chip microcomputer as the main control chip,using ADS1292 ECG Detection Chip,LMT70 temperature sensor and MPU6050 motion sensor to collect the parameters such as heart rate,body temperature and movement step number of human body during movement.The upper computer is built by LabVIEW,through wireless transmission,real-time display of physical sign parameters and moving steps,super threshold alarm and data recording are realized.The test shows that the system is stable and accurate,the relative error of heart rate is 0%~1.67%,the relative error of temperature is 0%~4.11%,and the system error is less than 5%.Compared with the traditional monitoring system of human physical signs,it is more intelligent and more convenient to systematize and centralize the physical sign parameters and motion parameters of the human body in the state of motion.
