【摘要】 近年来，CIMS(Computer Integrated Manufacturing Systems，计算机集成制造系统)在离散行业中的应用越来越广泛。与此同时，国际市场的竞争日益激烈，迫使企业加速推出质量好、成本低的产品，以期更有力地参与市场竞争。于是，流程工业开始在本企业执行CIPS(Computer Integrated Process System，计算机集成过程系统)，即CIMS在流程工业的应用。本文旨在研究CIPS在钢铁行业中的应用。 由于CIPS源于CIMS，因此本文首先简要介绍了CIMS的相关内容，包括CIMS的概念、构成、实施等。接着给出了CIPS的定义，讨论了流程工业集成自动化的发展过程，研究了CIPS的内容、体系结构、关键理论技术，并对CIPS的研究进行了展望。 然后，在对钢铁企业生产过程和流程特点分析的基础上，对钢铁企业CIPS进行了具体的研究。在此基础上，鉴于我国钢铁行业整体自动化和管理水平较低的现状，从功能和控制两个方面提出了一种CIPS的4层体系结构，并提出了如何具体实施CIPS。 最后，以CIPS为指导，建立了某钢铁厂炼铁分厂高炉集成自动化系统，并构造了高炉铁水硅含量预报模型。前者采用SCADA／HMI(Supervisory Control And Data Acquisition／Human Machine Interface，监控及数据采集／人机界面)实现系统功能，网络连接采用工业以太网，以实现数据的透明化。后者基于BP神经网络建模，在对传统的BP算法加以改进的基础上，结合时间序列的方法建立神经网络预报模型。 经实际投产运行后，该集成自动化系统效果显著，铁水硅含量预报模型预报效果理想，达到了预期目标。更多还原

【Abstract】 In recent years, the CIMS (Computer Integrated Manufacturing Systems) has been applied in the discrete industry wider and wider. At the same time, in the face of the increased international competition in the global marketplace which has heightened the need to develop high quality and low cost products that can compete, the flow industry attempted to implement the CIPS (Computer Integrated Process System), i.e. CIMS application in the flow process industry. This paper aims at studying the application of CIPS in the steel trade.The CIMS are first introduced briefly in this paper, as CIPS is derived from CIMS. The content and structure of CIMS are presented. Then the CIPS is defined, and the development of the integrated automation in the flow industry is discussed. After the detailed comparison between the CIPS and CIMS, the primary content and and the key theories and technologies of CIPS are investigated.Next, based on the analyzing of the operations of the steel trade, the CIPS of the steel trade is studied. Considering the actuality of our country’s steel trade, A CIPS 4 layers systematic structure is presented. The implement of CIPS in the steel trade is also studied.In the end of this paper, according to the principle of CIPS, the iron-smeltery integrated automation system is build. Furthermore, a time-series prediction model is developed to predict silicon content in hot metal. The former uses SCADA/HMI(Supervisory Control And Data Acquisition/ Human Machine Interface) to implement system function, and the network is connected by industry Ethernet. The latter is based on improved BP neural network.The result shows the integrated automation system works effectively and the prediction effect of the model is ideal.更多还原
