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)

谐波抑制的一个重要趋势是采用有源电力滤波器，有源电力滤波器也是一种电力电子装置，且相关技术的研究也日渐成为研究的热点。本文阐述了几种常见APF的拓扑结构及各自的优缺点，详细分析了基于瞬时无功功率理论的谐波检测方法，比例控制和前馈控制两种电流环控制策略以及SPWM和SVPWM两种调制策略。(the harmonic suppression is an important trend of active power filters, active power filter is a power electronic devices, and related technologies are increasingly become a hot topic. This paper describes the topology and their advantages and disadvantages of several common APF, a detailed analysis of the harmonic detection method based on instantaneous reactive power theory, and proportional control and feedforward control of)
