摘要
针对石化企业MES系统中的历史数据库部分，介绍了用VC实现从PHD实时数据库到ORECLE的历史数据存储；在石油炼油与化工运行系（MES）实施中，PHD实时数据库是系统的一个模块，通过自带的RDI（实时数据接1：2）连接DCS和PLC等数据采集设备．并通过PHD—PHD的数据采集方式实现了对大量重要的实时生产数据的采集、加工和处理以及对大量的历史数据的长期存储，并能提供多种访问PHD服务器数据的方式。论述了PHD实时数据库的数据采集方式、数据存储和数据处理。介绍了PHD Server访问数据的主要方法，并提出了应注意的几点问题。
In the allusion to the historical database of petrochemical enterprise＇s MES System, this paper introduced how to realize the storage from PHD real-time database to ORECLE historical database by using VC; in the implementation of petroleum refining and chemical industry operation system, PHD real-time database is a module which connects DCS, PLC and other data collection device with self＇s RDI, and collects and processes large amount of real-time producing data in PHD-PHD data collection mode. This module can save large amount of historical data and provide multi means for access to PHD server data. This paper also discusses the PHD real-time database＇s data sampling mean, data storage mean and data processing mean, introduces main access data mean of PHD Server, and provides some questions needing attention.
