【摘要】：我国水泥行业目前存在着产能过剩、能耗过高等问题,解决问题的关键就是淘汰落后的产能,降低企业能耗,优化生产工艺参数,提升水泥产品的质量。对水泥企业来说,生产和管理都需要越来越精细的水泥生产数据,也就面临着海量生产数据的存储和管理问题。本文在分析水泥生产数据的基础上,研究利用计算机和网络等信息技术对水泥生产数据进行科学有效的存储及管理。本文的工作主要体现在以下几个方面:(1)研究水泥工艺,对生产数据的来源进行分析,将生产数据分为原始数据、基础数据、报警数据和报表数据,总结出生产数据具有来源广、种类多和数据量大的特点。(2)综合考虑水泥企业的地理分布特点和基础网络等因素,为提高系统的可用性,研究采用分布式的存储方式进行生产数据的存储。采用磁盘阵列和双机热备技术,完成了集团总部和水泥分厂的物理存储;采用SQL server作为数据库,完成了集团总部和水泥分厂的数据库与数据表设计。(3)研究分厂数据库到集团总部数据库的数据同步技术。依照生产数据的数据特点和同步要求,设计采用SQL server复制技术和WebService技术解决了数据从分厂到集团总部的数据同步问题;为提高数据同步的可靠性,设计和开发了数据同步的监控和维护模块。(4)研究生产数据的访问控制技术。在数据访问控制方面,采用基于角色的访问控制模型对用户访问权限进行控制;在数据访问上,采用.NET三层架构的数据访问模式进行生产数据的访问,提高了数据访问的安全性和访问数据的灵活性。该研究项目已在多家水泥企业中得到应用,为企业管理和优化控制提供了全面、高效的数据支持,提高了企业的信息化水平。
[Abstract]:The problems of overcapacity and excessive energy consumption exist in the cement industry of our country at present. The key to solve the problem is to eliminate the backward production capacity, reduce the energy consumption of enterprises, optimize the production process parameters, and improve the quality of cement products. For cement enterprises, production and management need more and more fine cement production data, so they are faced with the problem of storage and management of mass production data. Based on the analysis of cement production data, this paper studies the scientific and effective storage and management of cement production data by computer and network information technology. The work of this paper is mainly reflected in the following several aspects: 1) studying cement technology, analyzing the source of production data, dividing production data into raw data, basic data, alarm data and report data, summarizing that production data has a wide range of sources. In order to improve the usability of the system, the distributed storage method is studied to store the production data in order to improve the availability of the system. The physical storage of headquarters and cement plant is completed by using disk array and dual-computer hot standby technology, and SQL server is used as database. The database and data table design of the group headquarters and cement branch plant is completed. The data synchronization technology from the branch plant database to the group headquarters database is studied. According to the data characteristics and synchronization requirements of production data, SQL server replication technology and WebService technology are used to solve the problem of data synchronization from branch factory to group headquarters, in order to improve the reliability of data synchronization, Design and development of data synchronization monitoring and maintenance module. 4) Research of production data access control technology. In the aspect of data access control, the role-based access control model is used to control user access rights, and in data access, the data access mode of .NET three-tier architecture is used to access the production data. The security of data access and the flexibility of accessing data are improved. The research project has been applied in many cement enterprises, which provides comprehensive and efficient data support for enterprise management and optimization control, and improves the information level of enterprises.
