Large Capacity Information Storage Method for Ocean Monitoring Equipments
Shiyang Zhang · Ocean Technology · 2011
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.
