摘　　要：目的:研究基于MSP430单片机和CH376接口芯片的U盘方式心率失常记录仪存储系统的设计和实现。方法:以MSP430单片机为核心,采集到的人体心电信号经模拟数字转换器(ADC)变为数字信号输入到MSP430中,单片机将数据通过CH376接口芯片写入U盘中。结果:实现了MSP430单片机对CH376接口芯片读写操作的控制,将采集的心电数据实时存储于U盘。结论:基于MSP430单片机和CH376接口实现心电信号的存储是可行的,完全满足心率失常记录仪的存储心电信号和采集数据的要求。Objective： Research based on the design and implementation of MSP430 and CH376 storage system of arrhythmia recorder which on the U disk way. Methods： With MSP430 single chip microcomputer as the core, the collected human ECG signals were turned into digital signals which stored in MSP430 through the AD converter, then MCU write datum to U disk by CH376. Results： It realizes the read and writing functions of interface chip CH376 from the control of MSP430 microcontroller, which let the acquisition of ECG signal output to the U disk. Conclusion： ECG signals for storage based on MSP430 microcontroller and CH376 interface chip is feasible, and the method can completely satisfy the ECG signal storage and data collection of arrhythmia recorder.
