摘要
遥感数据远程备份的目的是实现遥感数据的动态备份和快速恢复,确保遥感数据的安全存储与可靠访问。任务管理是遥感数据远程备份中的重要技术之一。本文对遥感数据远程备份中涉及的任务进行分析,提出一种任务管理方案,然后从任务创建、任务运行、人机交互、异常处理四个方面详细论述这一方案,最后基于该方案实现了遥感数据远程备份任务管理子系统。
The purpose of remote sensing data remote backup is to achieve the dynamic remote sensing data backup and rapid recovery,to ensure the security of remote sensing data storage and reliable access.Task management is one of core technologies of remote sensing data remote-backup.Through analysing the tasks involved in remote backup of remote sensing data,this paper proposed a task management program,and then discussed this program in detail from the task creation,task running,human-computer interaction,exception handling,the last remote sensing data remote backup task management subsystem was carried out based on this program.
