摘要
设计了一种基于虚拟仪器的心率监测系统。该系统由STC12C5A60S2单片机最小系统、心率传感器与上位机组成。STC12C5A60S2单片机具有片内AD转换器,可以直接采集心率传感器输出信号,并通过串口发送测量数据至上位机。在上位机利用虚拟仪器设计软件LABVIEW对采集的信息进行实时处理,实现心率的实时测量、心跳波形的实时显示及数据存储。该监测系统体积小,功耗低,能对心电信号实时显示和存储,适合家庭使用,对心血管疾病的预防和长期监护具有重要意义。
A new type of heart rate detection system based on LABVIEW is developed in the paper. The system consists of STC12C5A60S2 MCU minimum system, heart rate sensor and computer machine. STC12C5A60S2 microcontroller with onchip ADC can acquis heart rate sensor output signal directly, and send measurement data to PC machine through the serial port,in the PC machine Lab VIEW software is used to process collection information, realize the real-time heart rate(HR) monitoring, display heartbeat waveform and storage data. The monitoring system has the advantages of small volume, low power consumption, real-time ECG signal display and storage, suitable for family use. And it has important significance for prevention and long-term monitoring of cardiovascular disease.
