摘要
心率与体温是衡量人体健康的重要指标,为了快速、便捷对心率和体温同时测量,设计了一种简易的集心率、体温测量于一体的装置。系统硬件以单片机AT89C51为核心,采用DS18B20温度传感器采集体温信号,MPX2100压力传感器采集心率信号,送入单片机AT89S51,软件采用C语言编程,将采集到的信号由AT89C51运算处理后,再由液晶显示出来。系统经Proteus仿真表明,符合设计的预期要求。
Heart rate and body temperature are important indicators to measure the health of human body. In order to measure heart rate and body temperature quickly and conveniently at the same time,this paper designs a set of simple de- vice to measure heart rate and body temperature. The hardware of the system based on AT89C51 SCM as the core,adopts temperature sensor-DS18B20 to acquire the signal of temperature,and it adopts pressure sensor-MPX2100 to acquire the signal of heart rate, then it sends them into microcontroller-AT89S51. The software uses C language programming to processes the collected signals by AT89CSland then displays them through the liquid crystal. The system shows that it accords with the expected design through Proteus simulation.
