摘要
心率是衡量人体健康的重要生理指标。为了快捷有效地检测心率数据,设计了一种基于低功耗STC15L2K60S2单片机的腕带式无线心率检测仪。采用反射式光电传感器SON1303检测心率信号,通过硬件电路进行模拟信号处理后,单片机运行软件程序完成心率计算和数据处理,并借助CC2540蓝牙模块实现与上位机的无线通信。上位机软件基于Lab VIEW编写,可进行心率数据的监控和管理。腕带式佩戴方式和可充电锂电池供电对于心率检测更具便携性和实用性。样机测试表明,该设计具有良好的响应速度和准确性,适合在家庭和办公场所使用。
Heart rate is an important physiological index to measure human health. In order to effectively detect the heart rate data, a wrist-wear wireless heart rate detector is designed based on low power consumption single chip microcomputer STC15L2K60S2. Adopting reflection type photoelectric sensor SON1303 to detect heart rate signal, using hardware circuit to perform analog signal processing, the single chip microcom- puter runs software to complete heart rate calculation and data processing, and realizes wireless communication with the upper computer with the aid of CC2540 Bluetooth module. The upper computer software is programmed based on LabVIEW, which can implement the heart rate data monitoring and management. Wrist wearing and rechargeable lithium battery power supply are more portable and practical for heart rate detec- tion. Prototype tests show that the design has good response speed and accuracy, and is suitable for home and office use.
