在研究比较了多种嵌入式实时操作系统后,采用嵌入式实时操作系统VxWorks,在扩充的海量flash上运行文件系统来管理数据和代码,可以很好的解决试验数据的记录和传输问题。为了更有效地管理大容量的nandflash存储芯片上的数据文件,在VxWorks系统上设计了文件系统,实现了TureFFS块设备驱动,与本机dosFs文件系统挂接的在海洋监测仪器内测记录节点,从而解决系统信息的大容量存储和快速导出的方法。
After comparing a variety of embedded real-time operating system, the use of embedded real-time operating system VxWorks, in the expansion of massive flash file system to run on the management of data and code, can be a good solution to test data recording and transmission problems. In order to manage the data files on the nandflash memory chip more efficiently, a file system is designed on the VxWorks system, which realizes the TureFFS block device driver and records the nodes recorded in the marine monitoring instrument with the native dosFs file system. So as to solve the large-capacity system information storage and rapid export method.
