基于SON1303的简易运动心率仪设计

Design of Simple Exercising Heart Rate Meter Based on the SON1303

为适应运动状态下的心率检测,以低功耗微控制器STC11L01E为控制核心,采用性能优秀的绿光光电反射式传感器SON1303采集心率信号,并通过滤波、放大、信号调理再送入微控制器处理,设计平滑抗干扰算法得到的心率数据由数码管实时显示,在心率失常时给出报警信号。经实物检测心率准确率达到98%以上,可有效检测心率。整个系统采用低功耗设计。

In order to adapt to the heart rate detection under the state of motion, using the low power con-sumption microcontroller STC11L01E as the control core, and using the performance excellent green photoelectric reflection sensor SON1303 to collect the heart rate signal, and through filtering, amplification, signal conditioning. Then send microcontroller to process, the heart rate data displayed on LED numeric tube after smooth anti-jamming algorithm and issue alarm signals when the heart rate is abnormal, the accuracy of heart rate was more than 98.5% under physical detection, so it’s effective. The whole system is designed with low power consumption.
