摘要
介绍了一种基于AT89C52单片机的具有脉搏检测与显示功能的智能脉搏测量器。运用AT89C52准确测量计算出每分钟的脉搏数,测量结果用LCD显示。系统中采用HK-2000A集成化脉搏传感器,利用测周法进行脉搏测量,采用防脉冲干扰滑动平均法进行数据处理,因而在提高精度的同时也大大提高了系统的响应速度。重点进行了软件的设计,运用Proteus成功进行了仿真与调试。测试结果表明,系统功能较强、工作稳定且使用方便。
This paper describes an intelligent pulse measuring device based on AT89C52, with a pulse detection and display functions. It uses AT89C52 to measure pulse rate per minute accurately, and the measurement results are displayed in LCD. The system uses HK-2000A integrated pulse sensor and the method of cycle measurement is used to monitor the pulse rate, and the moving average algorithm is applied to data processing. The accuracy is thus improved and the response speed is also increased. The software design uses the Proteus successfully to simulate and debug. Test results show that the system is more powerful, stable and easy to use.
