一种新型的动态心电数据存储器设计

设计了一种基于SD卡的动态心电数据存储器。本存储器由四个模块组成，心电采集模块完成心电数据的采集、SD记忆卡读写模块可以实现大容量心电数据的暂存，模数转换模块实现模拟心电信号的数字化，LCD显示模块可用来显示系统菜单和状态信息。主机与各模块之间的数据传输通过两种总线协议串行外围设备接口SPI总线和内部集成电路12C总线实现，并给出了部分接口电路。本心电数据存储器具有很好的稳定性，但干扰性能强、具有长达30d的存储能力。

Design of a new Holter data memory

A Holter-based SD card data storage has been developed. It consists of three modules, such as ECG acquisition module, SD Card Memory Modules, USB data communication module and LCD module. SD memory card reader module can achieve large-capacity temporary storage of ECG data. And analog-digital conversion module can do for analog to digital ECG. LCD displaying module can be used to display the system menu and status information. The host and the module data transfer between the two kinds of bus protocol via a serial peripheral interface SPI bus and the internal IC I2C bus for realization. And it gives-some of the interface circuit. The Holter data memory has not only a very good stability, but also do interfere with performance. Meanwhile, it is strong and has storage capacity up to 50 days.
