一种用于声纳系统的高速数据实时存储系统

在声纳工程领域,试验数据都是不可多得的宝贵资料,因此经常需要对大量数据进行实时存储。Windows操作系统能在一定程度上满足大量数据的存储,但实时性不够好。本文提出了一种基于嵌入式实时操作系统VxWorks的海量数据存储方法,并解决了大硬盘的I/O访问、数据在Windows操作系统下转存的问题,这些方法都已经得到了实际的应用。

A Design of Fast Real - time Data Storing System for Sonars

In Sonar engineering,experiment data are precious,so they often need to be stored on disks in real-time.Windows OSes can sometimes fulfill the storing of masses of data,but it has limitations in real-time applications.In this article,a method for storing massive data on embeded real-time OS VxWorks is proposed.At the same time,the problem of I/O access of a large hard disk on VxWorks is also solved in this article.And as another important part of this application,how the data stored under VxWorks to be converted to separate files under Windows OS is also mentioned.All methods in this article have already been applied in real systems.
