摘　　要：采用USB Host器件CH375与通用型单片机AT89S52实现U盘接口,设计了海底取样钻机传感器大容量数据采集系统。该系统遵守USB海量存储设备类规范和软件协议,支持FAT16文件系统。大量现场采集数据可以及时保存到U盘中,并且可读取U盘通过显示器以文本或曲线方式进行数据回放。利用U盘的良好移动性,方便与计算机进行数据交换,达到现场大容量数据采集、室内数据分析的目的。该仪器为海底地层的特性分析提供了重要的技术手段。Based on the method that used USB Host of chip CH375 and universal SCM AT89S51 to carry out USB disk interface, this paper designed a data acquisition system of the seabed sampling large capacity drilling rig sensor. The system complied with the USB mass large storage class standard and software protocol to support the FAT16 file system, Large number of real-time data could be collected to the USB disk, and these data could be read through the display of text or diagram, Based on the good mobility of USB disk, it is convenient to exchange the acquired data with computer, so it realizes large-capacity data acquisition and indoor data analysis, The instrument provides an important method to analyze the characteristic of seabed strata.
