摘 要: | 介绍了EMTDC软件快照功能的基本原理,提出了一种基于数据整体存取技术实现EMTDC仿真模型快照数据存取功能的方法。该方法以应用程序为单位构造成员变量结构体,以结构体为单位对快照数据进行存储空间的分配和恢复,以页面为单位进行数据的刷新,不需要区分单个变量的数据类型,也不需要为每个变量分别添加快照功能的处理代码,有效地提高了程序代码的开发效率和执行效率。

Application of Overall Data Storage Approach in EMTDC Snapshot |
| |
Abstract: | This paper introduces the fundamental theory of EMTDC snapshot,and promotes an approach based on data-entity access technique to realize data read and write of EMTDC snapshot.The approach uses application program as basic unit to construct structure of member variables,uses structure of member variables as basic unit to allocate and recover memory space of snapshot data,and uses page as basic unit to update snapshot data.The approach needs neither to distinguish the type of single variable,nor to add code to process each variable of the snapshot data,thus efficiently increase the efficiency of the program's develop and execution. |
