摘　　要：针对金属冶炼行业实时监控系统的开发过程中软件复用度低的问题,设计并实现一种iHistorian实时数据库访问构件。该构件为开发人员提供了基于组件对象模型(COM)的接口,实现了iHistorian实时数据库的存储、数据查询及数据转发功能,解决了一个iHistorian连接授权,多个客户端访问的问题。该构件被封装成动态链接库(DLL)文件,可方便地在基于iHistorian的实时监控系统中复用,从而缩短了软件开发周期,降低了软件开发成本。该构件已在"大型设备实时监控系统"中得到成功运用。A kind of iHistorian real-time database accession component is presented,aiming at the problem of low scalability of the realtime monitoring software development in the metal smelting industry.This component provides interface based on component object model（COM） and has the functions of iHistorian real-time database accession,querying data,in database and real-time data transmitting.Also more than one client access iHistorian real-time database which has one hardware key by the component.The component is packaged dynamic linkable library（DLL） file and reuse in the real-time monitoring system.The software development cycle is shortened and the software development cost is reduced.The component is used in large equipment real-time monitoring system successfully.
