根据心电信号的特征以及本课题的具体要求，基于单片机心电信号数据采集的设计主要包括有以下几个部分。首先是模拟信号的处理，得到的信号传送到AD转换电路进行模数转换，出来的离散数字信号，经过单片机控制器处理后上传给上位机处理和储存，或者可以设计DA转换器把数字信号再转换为模拟信号方便示波器的观察。当然，系统中还要有个电源电路为各个芯片提供电压。
Data collection system is also a core component, including simulation of the collection, the collection of figures, and figures of export volume control signals. According heart electrical signal characteristics and the specific requirements of the topic, based on data collection Chanpianji heart electrical signal design include the following components. First, analog signal processing, signal transmission to be offered a module conversion conversion circuits, separated by the digital signal processing upload after Shanpianji controller to win the processing and storage, or can design DA converters to digital signals to analog signal conversion for the convenience oscilloscope observation. Of course, the system also has a power circuit voltage to the chip to provide.
