基于USB-Host的大容量数据采集方案研究

摘要

针对目前数据采集系统面临的不足,介绍了一种使用U盘作为存储介质的大容量数据存储方案。该方案使用C8051F020单片机作为主控制器,CH376则工作在USB-Host方式下通过USB接口完成对U盘的识别与数据的写入。经过软硬件的测试,该方案能够成功实现大容量数据采集功能,并可极大地方便户外作业,满足不同场合的需要。%In view of the insufficiency in data acquisition system,this paper introduces a mass storage data collecting system using U disk storage media.The system uses C8051F020 as a main controller.CH376 worked in the way of USB-Host which can complete identifying U disk and writing the data.After software and hardware testing,this program can realize the function of mass storage data acquisition successfully.This system brings enormous convenience to the work in the open air and can meet different needs flexibly.
