It is the adoption of isomerous dcs for units in a power station which makes the information of production process as a whole in a enterprise can not be synthetized and integrated , which block the all - around automation to realize in the enterprise . in allusion to the problem , the paper following put forward a solution scheme of establishing a general data interface facing dcs control system . on the base of which , establishing a general data interface facing symphony and ovation dcs system , and thus realizing the synthesis and integration for real - time data between two dcs system 通用数据接口将电力企业的底层生产网络与上层管理信息系统连接起来,它向下采集并综合处理和存储底层不同dcs控制系统的生产过程信息,并屏蔽各个dcs控制系统开发平台、网络通讯协议以及数据格式的互异性为上层管理信息系统提供实时数据与历史数据,从而使得所有与生产运行有关的决策者、操作者及相关的应用程序都可以很方便及时得获得当前生产过程的实时数据和历史纪录,同时这个数据接口也将上层管理信息系统的指令、决策以及相关程序指令传送给底层相应的具体生产设备。
