基于ARM9和FAT的高速海量数据采集系统

摘要

针对一些控制系统,为了能够快速获取实时数据,并借助上位机系统进行离线分析,提出了移植FAT文件系统到ARM中,将实时采集的海量数据保存到SD卡的设计方案;该方案以S3C2440 ARM9为嵌入式平台,结合文件系统和SD卡存储技术设计了数据采集系统,应用MATLAB等软件对数据进行分析处理,实现了对控制系统模型的矫正;经飞思卡尔智能车系统的设计证明,这种方案在系统建模和系统特性分析上具有较强的应用价值.%A design of high speed mass data acquisition system is introduced, which is designed to acquire mass real time data from some control systems, and to do off-line analysis by PC. The design is based on S3C2440 ARM9 embedded platform combined with FAT file system and SD card storage technology, and it uses MATLAB to analysie the obtained data with the purpose to adjusting the control system model. The design of Freescale intelligent car system proves that the system works well and is valuable to the modeling and performance analysis of the system.
