摘要
分析了实时数据库的结构特征和设计的流程,深入研究了目前数据库技术常用的算法,描述了实时数据库系统结构框架,给出了应用于微机线路保护上位机软件中的实时数据库的数据模型及数据库的具体实现过程。在此基础上运用Visual C++编程,实现了模块化程序设计。对所编制的软件进行了测试,结果表明,实时数据库系统满足设计要求,系统性能达到了预期的目的,可以应用于实时性要求较高的变电站综合自动化之中。
The real-time database structure frame of the system is brought forward. The data model and the realization process of the real-time database are given out, which applied to the field of substation automation system microcomputer protection software. Based on this methodology, the software system realizes modularization programming using VC ＋ ＋. Finally, the software programmed is tested. The test results show that the real-time system can satisfy the design requirement, and system performance had achieved the expected target. Compared with the traditional database systems, it also has the merits of high storage and query speed and can be applied to the substation automation system with high real-time requirement.
