基于通用数字声纳平台的软件备份技术研究

Research of Software Backup on a General Digital Sonar Platform

按照软件工程的思想,运用读取代码、验证代码、备份代码的方法备份系统软件,通过对专用存贮芯片的代码重写,解决专用存贮介质上软件备份的难题,实现通用与专用存贮介质的软件备份,达到通用数字声纳平台软件备份研究的目的。为数字声纳装备的软件维护,特别是军用声纳装备的战场快速保障提供了借鉴参考,具有重要的现实意义。该文从软硬件两方面解决了专用存贮介质上声纳软件备份的难题;实现了多种文件系统及不同存贮格式上的系统软件备份;在软件备份研究中汲取了软件工程的思想。

According to an idea of software engineering,system software backup is accomplished by the reading of codes, writing of codes and backup of codes. In order to settle the problem of special storage medium backup, by rewritting the codes of chips, research of software backup on a general digital sonar platform of general and special storage mediums is achieved. It offers references for software maintenance of digital sonar, especially fast safeguard of military sonar in a battlefield. The innovation points of this article include：settle the problem of special storage medium backup from software and hardware, achieve system software backup on multi-file systems and different storage format,derive software engineering idea for research software backup.
