基于SCADA系统的中间数据库系统在油气管道调控中心的应用

摘要

中间数据库系统是用于采集和存储SCADA系统数据，作为SCADA系统数据对外应用的平台，其他各应用系统与中间数据库通过接口交换信息。这样既保障了SCADA系统的安全，又满足了各项业务的需要。 SCADA系统实时服务器与中间数据库系统数据采集接口服务器的通信将采用OPC方式；中间数据库系统发布成以OPCSERVER和ODBC数据接口，供PPS、ERP、泄漏检测、离线仿真等应用系统提供数据支撑；OPC接口服务器负责将管道运行参数实时写入到中间数据库系统中，SCADA系统与应用系统无直接的数据接口，全部通过中间数据库服务器为各种应用提供数据。为提高中间数据库系统的时效性，其网路架构应和SCADA共存于一个网络之内，若实际要求不允许的话，可通过网闸及核心交换机内置的防火墙与SCADA系统进行物理隔离。%Intermediate databases system is used for data acquisition and storage SCADA system, as an external application of SCADA system data platform, among other various application system and the database through the interface to exchange information. This is to ensure the safety of the SCADA system, and meet the needs of each business.SCADA system real-time server and database system between data acquisition interface way of communication will use the OPC server. Among the OPCSERVER and ODBC database system is released into the data interface, for PPS, such as ERP, leak detection, offline simulation application system to provide data support.OPC interface server is responsible for the pipeline operation parameters real-time written to intermediate databases systems, SCADA system and application system is the direct data interface, all through the intermediate databases servers to provide data for a variety of applications.To improve the efficiency of the database system and among its network architecture with SCADA coexist in a network, if the actual requirements is not allow, can through the gate and core switches the built-in firewall and physical isolation SCADA system.
