中文摘要	The paper designs a module of data storage with U-disk based on index file. It meets the fast storing requirement of a great deal of original data gained in the online profile measurement system of spiral weld steel pipe with large diameter. The module consists of DSP control system and extended USB host chip named CH375. It realizes the function of data storage in the U-disk, using the program that embedded in DSP. A format of data storage based on index file is applied to improve the speed of file storage, and it leaves out the searching work of FAT area and root area on the U-disk. Experiments show that the module is stable and has excellent transplantation. The module can be used in many other systems that need the function of fast data storage.
