呼吸监测系统的研究

Research on Implementation of Respiratory Monitoring System

采用AT89C52单片机作为核心控制模块,经过A/D处理技术将呼吸模拟信号转换为数字信号,并通过DS1302时钟的计数、AT24C02的EEPROM存储设备将信息读取到LCD12864液晶显示器上。该系统用于监测、记录人体呼吸不良时的血氧饱和度参数值,并在不良时给予警报处理。此外,通过RS232进行串口通信将记录的数据传输到上位机(即PC机)达到远程监测的目的。

The design of respiratory monitoring system,by using AT89 C52 microcontroller as the core control module,transfers breathe analog signal into digital signal through A/D processing technology,and displays information on LCD12864 monitor by counting of DS1302 clock and EEPROM storage device of AT24 C02. The system is used to monitor and record oxygen saturation parameters of human respiratory,then to give the alarm processing in bad condition. In addition,it transfers the recorded data to the host computer（PC machine） through RS232 serial communication,so as to achieve the purpose of remote monitoring.
