摘要
利用51系列单片机开发指脉采集系统,以实现对社区或医院住院病人等的脉搏数据采集、存储、报警等功能。该系统采用低功耗的AT89C2051单片机作为处理器,利用计时中断的方法计算脉搏信号的频率,结合液晶显示器显示测量结果。该系统具成本低,实用性强等特点。有较好的市场前景,符合便携式数字化医疗器械的发展需求。
Using 51 series MCU to develop a finger pulse collection system to gather the pulse data among the patients in communities and inpatients, the functions of storage and alarm are also provided.The processor is a low-power MCU, i.e.AT89C2051, time interrupt is set to measure the pulse rate. With the LCD, doctors will easily read the results and refer to any storing data.
