精简FAT文件系统在数据采集中的应用

Reduced FAT file system applied to data acquisition

针对控制系统为了能够获取实时海量数据,并借助上位机系统对获取的数据进行离线统计、分析,提出了精简FAT文件系统的方法,并将其移植到控制系统的微处理器中,把实时采集的数据保存到SD卡的设计方案。该方案具有占用系统空间小、运行效率高、海量数据存储、可移植于各种单片机系统的特点。经智能车系统的设计证明,该方案具有较强的应用价值。

In order to acquire real-time mass data and to do off-line analysis by PC,A method of reduced FAT file system is introduced,which can be transplanted to the MPU of some control systems that save real time data into SD card.This reduced FAT file system requires less system space and operates efficiency,and can be transplanted every kind of MPU to save mass real time data.The design of intelligent car system proves that the design works well and of strong using value.
