摘　　要：介绍了一种由 8Xc196单片机控制的用于检测人体呼吸节律、体温参数监护仪的设计。系统采用液晶显示器 ( L CD)作为显示屏 ,具有实时显示呼吸波及其频率、体温参数以及呼吸频率、体温 2 4 h趋势图和自动报警功能。并可通过 RS2 3 2接口与This paper introduces the design of a monitoring system to measure the respiration and temperature of a body with an 8Xc196 single-chip microcomputer. This system can measure and display the respiration wave, respiration frequency and the body temperature in real-time with a liquid crystal display (LCD) and give an alarm when the parameters are beyond the normal scope. In addition, this device can provide a 24 hours trend graph of the respiration frequency and the body temperature parameters measured. Data can also be exchanged through serial communication interfaces (RS232) between the PC and the monitor.
