摘　　要：提出一种基于ARM和μC/OS-Ⅱ的SD卡嵌入式文件系统设计,其主要功能是用文件的形式记录列车发电车厢油量信息,为控制、降低列车油量消耗提供了一种很好的解决方案.该系统设计分为硬件和软件两部分:硬件由LPC2210控制SD卡座实现;软件采用C语言和汇编语言混合编程.只需修改本系统的少量底层驱动代码,便可嵌入至其他目标系统中.A design of the SD card embedded file systems based on the ARM and μC/OS-Ⅱ is proposed. The main function of this system is to record the oil consumption information in the form of FATFS. It provides a good solution to control and reduce the train＇s oil consumption. The system is composed of softwares and hardwares. The hardware part is realized by LPC2210 which controls SD card. The software part is realized by using assembly language in conjunction with C code. For the other embedded use ,only a small number of amendments to the system＇s underlying code drivers are needed.
