A solution of file management system is proposed for MCS-51 based devices that are mainly used as various remote controllers. Storage devices such as SD are used to keep data and command contents that are received via network. Remote controllers listen, receive, and execute commands that come from network. A SD control circuit is proposed in the paper and a FAT32 file system for SD is realized to make it possible to collect, store, query, and maintain large amount of data for remote controllers.%本文提出一种基于MCS-51系列单片机的文件管理系统。它主要适用于远程控制设备，通过SD卡等存储设备实现通过局域网传输的控制命令信息的存储和管理。远程控制设备监听并接收通过网络发送过来的控制命令、根据控制中心的命令及时准确地对其控制对象进行控制。文中设计了远程控制设备的SD卡控制部分硬件接口电路，按照FAT32文件系统规范实现了基于SD卡的文件系统，以实现远程控制设备对大容量数据信息的采集、存储、查询、维护和管理。
