ECG
基于单片机的ECG数据采集与预处理
本课题首先介绍了心电信号检测电路的设计，给出了心电信号采集电路具体的设计方法与部分实现电路。并采用了线性光电耦合器放大电路，对前置级运算放大电路及后置级放大电路进行光电隔离，有效地抑制了各种干扰。 其次，主要进行基于AT89C52低功耗MCU的便携式心电监护仪及其系统的研究。
根据人体心电信号的特征，设计性能优良的心电信号采集系统，选用低功耗8位单片机AT89C52和大容量Flash存储器对采集的心电信号进行记录、分析及处理(MCU-based ECG data acquisition and pre-treatment of the subject introduced first ECG detection circuit design, are given specific ECG acquisition circuit design method and some realization of the circuit. And the use of a linear optocoupler amplifier, the pre-amplifier circuit-level operations and post-class amplifier circuit for photoelectric isolation, effectively a variety of interference suppression. Secondly, AT89C52 mainly low-power MCU-based portable ECG monitor their systems. ECG in accordance with the characteristics of the human body, the design performance of the ECG acquisition system, selection of low-power 8-bit MCU AT89C52 and large-capacity Flash memory on the acquisition of the recorded ECG, analysis and processing)
