摘 要
本设计是在 PROTEUS 环境下完成的，以单总线数字温度传感器
DS18B20、AT89C51 单片机、HK-2000A 集成化脉搏传感器、ND-3 微振
动传感器、LM041L 字符型显示器构成的多功能实时生理参数监测仪
系统的硬件电路及软件系统的设计。本文介绍了 PROTEUS 和 KEIL 软
件， DS18B20 单线数字温度传感器、AT89C51 单片机和 LM041L 字符
型显示器的结构、性能特点以及工作原理，以及 HK-2000A 集成化脉
搏传感器和 ND-3 微振动传感器的性能参数。该系统可以完成对温度、
心率、步数等参数的采集、处理和显示，并且能在这些参数超过设定
的阈值时，进行报警提示。

AbstractMy
design is depend on PROTEUS, using the extensively used
single-bus digital temperature sensor DS18B20, AT89C51 MCU,
HK-2000A integrated pulse sensor, ND-3 micro-vibration
sensor, LM041L character display design a multi-functional
real-time physiological parameters monitor,s hardware
circuits and software system.PROTEUS and KEIL software,
DS18B20 single-wire digital temperature sensor, AT89C51 MCU
and LM041L character display structure, performance
characteristics and working principles, as well as the
HK-2000A integrated pulse sensors and ND-3 micro-vibration
sensor performance parameters is introduced in this paper.
This system can be completed on collect, processing and
display the parameters the temperature, heart rate, paces,
and more than these parameters in the threshold that we set
for alarm.
