高性能实时数据库组件设计

高性能实时数据库系统组件设计,可以解决电力、通讯、石油、化工、冶金、制造业等产业型企业,进行信息化与自动化系统建设时,所面临的管理信息系统与SCADA(Super Control and Data Acquisition)系统怎样进行实时信息交换的问题,以及在网络环境下怎样实现不同平台的应用系统的信息共享问题,怎样提供标准和开放的访问实时信息的方法问题,以及如何提供方便的在线维护实时数据信息点的手段问题。建立在基于TCP/IP协议的客户机/服务器模式和“查询”、“Push”和点对点(Peer To Peer)主动数据传递方式的数据通信技术的层次化网络SCADA(Super Controland Data Acquisition)模型上的实时数据库系统组件(Real Time Database,简称RT-DB),完全满足产业型企业高速数据通信、高可用性、系统稳定性、可维护性等高性能指标的需要,可以充分解决上述问题。实践证明,应用高性能实时数据库组件提升产业性企业的信息化与自动化系统的性能是十分有效的方法。

A DESIGN FOR THE REAL-TIME DATABASE COMPONENT WITH HIGH ABILITY

While the information, or automation system is constructed for the industry enterprise in the realm of electrical power, communication, petroleum, chemical engineering, metallurgy,and manufacture etc, each developer must front the problems of how to carry on real-time exchange of information needed between the management information system and the SCADA (Super Control and Data Acquisition)system, how to share the information of the applied system with different platform in the networks, how to scheme the method of real-time data accessing with open and standard interface, and how to supply the convenient method of real-time data node maintaining on line. Based on hierarchical network SCADA communication model for the SCADA system, the real-time database (RTDB) component with high ability is designed for solving those problems, and is built by using Client/Server mode based on the TCP/IP protocol, the communication technique of data query, data push, and master/slaver data transferring for peer to peer. This RTDB component satisfies all capability of the applied system for industry enterprise to demand the high-speed communication, the high usability, the system stability, and the system maintainability etc. It is a very efficient method that RTDB component with high ability implement to enhance the capability of information and automation system for the industry enterprise.
