牵引变电所综合自动化系统中实时数据库技术

Real-time database technology in the comprehensive automation system for the traction substation

根据牵引变电所综合自动化系统的结构与特点,在分析实时数据和事务的特征基础上,提出了采用DCOM技术实现内存数据库的访问接口及共享方法;采用多串口服务器、以太网及交换机等的连接实现通讯;设计了牵引变电所综合自动化系统的一个驻留内存的实时数据库,实现对变电所信息的共享,提供给调度、管理和流程等系统控制。

The structure and characteristic of the comprehensive automation system for the traction substation are described, the characteristics of the real-time data and transactions are analyzed, the DCOM technology is used to realize the accessing interface of the memory database, and the sharing method of the memory database is presented. The communication is achieved by using the connection between the serial interface server, the Ethernet network and the switch. A real-time database of the comprehensive automation system for the traction substation is also designed to realize information sharing for the system control of scheduling, managing and flows.
