【摘要】：磨矿生产是整个选矿厂生产过程中的关键环节,磨矿自动化与信息化的发展水平直接影响整个选矿厂的生产能力和经济效益。近年来,自动化得到了快速发展,磨矿自动化技术也在不断提高,大型选矿厂成套DCS设备的引进为选矿厂带来了巨大收益,然而自动化系统与信息管理系统严重脱节,不能在自动化与信息化之间实现信息交换,使信息管理系统无法实时地获得现场的生产数据,给选矿厂的生产管理、信息管理、生产调度带来了巨大阻碍。为了避免“信息孤岛”现象的出现,将磨矿自动化系统与信息化系统有效集成到一起显得尤为重要。课题研究了目前广泛使用的自动化系统与信息化系统的集成技术和方法,在查阅大量参考文献和了解系统集成原则的情况下,详细设计了磨矿自动化与信息化集成方案。该文阐述了串口通信在下位机、上位机以及监管计算机中的实现方法。采用串口通信实现不同厂家、不同型号的PLC与不同组态软件间的数据通信,实现了下位机仪表与组态软件和监控计算机的数据集成,还实现了组态软件与信息监管平台间的数据交换。采用Visual Studio 2010设计了OPC客户端,采用C#语言编写的OPC客户端程序对Win CC或者Kepware等OPC服务器进行数据采集,将采集到的数据可以直接写入数据库服务器中,供磨矿信息化监管系统使用和分析,实现磨矿自动化系统与信息化系统的集成;此外还可以在OPC客户端中编写串口程序,再以OPC转串行通信的方式实现磨矿自动化系统与磨矿信息化监管系统的集成。最后对系统集成的不同方法在承德某选矿厂进行了测试,验证了可行性,课题论述的方法可直接用于磨矿自动化系统与信息化系统的集成。
[Abstract]:Grinding production is the key link in the production process of the whole concentrator. The development level of grinding automation and information directly affects the production capacity and economic benefit of the whole concentrator.In recent years, automation has been developed rapidly and grinding automation technology has been continuously improved. The introduction of complete sets of DCS equipment in large concentrator has brought great benefits to the concentrator. However, the automation system and information management system are out of step with each other.The information exchange between automation and information can not be realized, which makes the information management system unable to obtain the field production data in real time, which brings great obstacles to the production management, information management and production scheduling of the concentrator.In order to avoid the phenomenon of "information island", it is very important to integrate the grinding automation system with the information system effectively.This paper describes the realization of serial communication in lower computer, upper computer and supervision computer.The serial port communication is used to realize the data communication between different manufacturers, different types of PLC and different configuration software, and the data integration between the instrument and configuration software and the monitoring computer is realized.The data exchange between configuration software and information supervision platform is also realized.The OPC client is designed with Visual Studio 2010. The OPC client program written in C # is used to collect data from OPC servers such as Win CC or Kepware. The collected data can be written directly into the database server.The information supervision system for grinding can be used and analyzed to realize the integration of the grinding automation system and the information system, in addition, the serial port program can be written in the OPC client.The integration of grinding automation system and grinding information supervision system is realized by OPC to serial communication.Finally, the different methods of system integration are tested in a concentrator in Chengde, and the feasibility is verified. The method discussed in this paper can be directly used in the integration of grinding automation system and information system.
