摘要
众所周知,从计算机技术介入到工业控制应用领域开始,伴生的“信息孤岛”问题就一直困绕着业界。“信息孤岛”相当严重地限制了信息交换继而约束了应用领域的拓展。
     济南鲍德气体有限公司担负着济钢全公司的压缩空气、氧气、氮气等气体的供应任务。主要生产设备包括1~6#制氧机、水处理系统、集中空压机站、氧压机站等。现有的各控制系统种类复杂,型号各不相同,控制方式也不同。随着自动化生产的发展、管控一体化的要求和不同厂家系统之间系统融合的需要,同时也为了简化和降低不同系统对接成本的需要,应采用一些通用的技术手段来解决不同系统的对接问题,以实现不同厂家的硬件和软件所构成的计算机系统之间的数据交换和通讯。
     本文基于鲍德气体有限公司管控中心项目,本课题的主要工作是针对济南鲍德气体有限公司管控中心现有的各控制系统各自独立的情况,对实现各系统与服务器之间的数据通讯、网络安全以及信息Web发布等进行对象分析,根据现场实际运行情况,找出与不同厂家的硬件以及软件进行通讯的合适的通讯协议或合理的方案,彻底实现控制系统与管理系统的数据共享。
     在此基础上,在管控中心设置统一的管理监控平台,通过Web浏览器进行信息发布。让企业的上层管理者能够及时、直观地了解生产现场的运行情况。并将这些实时数据长期保存,对实时数据和历史数据进行各种数据挖掘分析(如厂级性能计算、厂级故障诊断、负荷计算等等),改变多个控制系统各自独立,无法进行综合分析,无法进行统一规划和利用全局资源的局面。同时也可以向上一级总公司能源中心系统提供其所需要的实时和历史生产数据。
     该项目在全国空分行业属于首次应用。它创新地实现了安全稳定的工业控制网与信息管理网的有机融合。采用不同通讯协议实现了复杂多样的数据源和采集平台之间的信息传递及安全隔离。实现了生产无扰的安全在线不停产改造和分布式Web的远程数据访问技术。数据的核算告别人为平衡的历史,使管理走向科学性、快速性和准确性。为济钢气体公司管理的扁平化奠定了坚实的基础。
It is well known that since the computer technology involved in industrial control applications, industries have been troubled by the problem of "isolated-islands of information". It seriously limits the exchange of information and also restrains the expansion of application fields.
     Jinan Baode Gas Co. LTD is a company to supply Jigang with different kinds of gas like compressed air, oxygen and nitrogen. The factory has many equipments that include No.1~6 oxygen plant, water-treatment systems, centralized air-compress stations and oxygen-compress stations. The existing control systems have complicated types, different models and control methods. With the development of the production automation, the requirements of integration between management and control, and the needs of gathering among the systems from different manufacturers, different problems docking system should be solved by using some common technical means. They can also simplify and reduce the cost of different systems docking. Therefore, data exchange and communications between computer systems comprised by different hardware and software made by different companies can be implemented.
     Based on the project, we firstly analyze the communication protocol, network security and reliability that each control system supports. Then we propose reasonable solutions based on industrial Ethernet and achieve data sharing of control and management systems.
     On this basis, managing and monitoring platform is settled in the managing and control center and information is distributed through a Web browser. Then the managers will directly know the situation of fieldwork in time. They can store the real-time data and doing different analysis of real-time data and historical data (such as factory-level performance, the plant level fault diagnosis, burthen calculation, etc.). Without this project, different control systems are independent. It is hard to do comprehensive analysis, unified planning and usage of global resources. At the same time, it can supply real-time and historical production data energy center system for upper corporation needs.
     The project is first application on air-separate vocation. It integrated industrial control network which operates safely and stably and information management network. It uses different communication protocols to transmit and separate data between complex resources and collection platforms safely. It achieves online non-stop improvement without disturbing production and Distributed Web and remote data access technology. It ends the history of artificial balance and makes the management scientific, fast and accurate. It also sets solid foundation of management for Jigang Baode Gas Company.
