摘要
现在的人们越来越注重自身健康,特别是老年人,他们需要定期体检,但是在医疗水平落后的区域定期体检很难实现。因此文中设计了一款以STC89C52单片机为控制核心,采用HKG-07A红外式脉搏传感器采集数据,通过A/D转换器,送给液晶显示测量结果。经过与医用脉搏测量仪比较,系统具有精度高、性能稳定、反应迅速、性价比高的特点,而且结构简单、使用简洁方便,具有很高的市场价值。
Now people pay more and more attention to their health, especially to old people, they needregular physical examination, but in the area of regular medical examination not developed, which is avery difficult to achieve. Therefore, this paper designed a STC89C52 microcontroller as control core,using HKG-07A infrared pulse sensor data collection, through the A./D converter, for liquid crystaldisplay measurement results. After testing and medical pulse comparison, this system has high accuracy,stable performance, quick response, highratio of performance to price, and has the advantages of simplestructure, the use of simple and convenient, has the very high market value.
