摘　　要：目的为实现远程猝死监测系统中对采集数据的保存及传输,设计并实现了一种基于STM32的数据存储及传输系统。方法系统将采集到的12位数据经过处理,变为212格式,然后将数据保存在W25Q128BV芯片中,最后经过USB接口上传至PC机进行后续的分析。结果实验结果证明该系统有效地节省了Flash空间,数据传输速度快。结论该数据存储及传输系统是远程猝死监测系统研究开发的基础。Objective In order to realize the data storage and transmission in the remote sudden death monitoring system, one data storage and transmission system based on STM32 is designed and achieved. Methods The 12-bit data is transformed to 212 format by data processing, saved in the W25Q128BV chip, transmitted to PC through USB interface for follow-up analysis at last. Results The experimental results show that the system can effectively save the capacity of the Flash and improve the transmission speed. Conclusions The data storage and transmission system is the foundation for the development of the remote sudden death monitoring system.
