一种实现海洋监测仪器大容量信息存储的方法

Large Capacity Information Storage Method for Ocean Monitoring Equipments

现代化建设对海洋监测仪器信息存储提出了更高的要求,尤其是要客观真实地反映实验现象,需要的测试点增多、记录数据量加大,使得许多小存储量海洋监测仪器不能满足当前实验的要求。通过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,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文件系统挂接在海洋监测仪器内测记录节点,从而解决了系统信息的大容量存储。最后通过利用该方法设计的钽丝测波仪进行实验,实验结果较好地还原了波浪的真实图像。研究的方法具有广泛的适用性,在其他海洋测试系统中也有广泛的应用前景。

Ocean exploration and military applications have put forward higher demands for ocean monitoring equipment.Especially imaging experiment phenomena with extension,manifold testing point and log data result in ocean monitoring equipments with small memory not suitable for applications.A method of data storage and transmission with the embedded operating system VxWorks and Ture Flash File System（TureFFS） drivers based on the NAND flash device is presented.To effectively manage the data files on the NAND flash storage chip of large capacity,a file system on the VxWorks system is designed to realize TureFFS communication with VxWorks dosFs on the ocean monitoring equipments.Thus,large capacity information storage of ocean monitoring equipment can be implemented.Finally,experiments using Tantalum thread wave measure equipment are conducted to verify the effectiveness.The scheme may be applied for other ocean monitoring equipment systems.
