针对现有的心率测量方法基本上要求测试人员处于静止不动的状态下进行测量这一问题,设计了一种由光电探头、信号处理电路、数据采集卡和电脑组成的双波长心率测量系统。并应用该系统对移动中的右手与应用HKG-07B指甲式红外脉搏传感器对同一人体静止的左手进行了对比实验。实验结果表明,双波长心率测量系统测量准确率高达96.8%,同时也证明了双波长心率测量系统适合于运动状态下的心率测量。 In view of the existing measurement method of heart rate basically requiring the tester to measure under the static state, a dual-wavelength heart rate measuring system composed of photoelectric probe, signal processing circuit, data acquisition card and computer is designed. And the system is used to compare the moving right hand with the HKG-07B fingernail infrared pulse sensor on the same human left hand. The experimental results show that the accuracy of dual-wavelength heart rate measurement system is up to 96.8%, and the dual-wavelength heart rate measurement system is also proved to be suitable for heart rate measurement under exercise.
