摘要

摘要: 针对综采工作面各系统进行数据对接过程中，需要频繁进行数据点表与语义对应，导致综采工作面系统互联和数据共享成本激增的问题，提出了一种基于过程控制统一对象模型（OPC UA）的智能化综采工作面信息模型。根据智能化综采工作面的物理组成、功能模块及各模块间的信息流要求，采用面向对象的方式给出了智能化综采工作面信息模型架构。在该架构的基础上，对综采工作面中物理对象及开采过程数据进行数字化和模型化描述，形成工作面级信息模型。详细介绍了信息模型中基础组件、监控组件集与功能组件集对象涉及的静态属性集和过程属性集的各类元素。采用OPC UA与统一建模语言（UML）联合建模方式对智能化综采工作面信息模型进行实例化：利用UML类图辅助进行信息模型结构的描述，然后转换为OPC UA信息模型XML描述文件，将信息模型结构数据和属性数据映射到OPC UA地址空间模型，启动OPC UA服务器。实际应用结果表明，综采工作面各系统可访问服务器地址空间，顺利获取智能化综采工作面信息模型的结构和对象数据语义，从而快速完成数据的采集、入库和更新。为验证信息模型的应用效果，在OPC UA服务器开发的基础上，开发了综采工作面信息管理与集成分析平台，现场应用试验表明，平台显示的监控数据与现场实际运行结果一致，后台数据均来源于地址空间信息模型，从而验证了信息模型结合OPC UA协议实现综采工作面信息互联互通的可行性。

Abstract: In the process of data connection of each system in fully mechanized working face, it is necessary to perform frequent correspondence between the data point table and the semantics, which leads to the surge of system interconnection and data sharing cost of fully mechanized working face. An information model of intelligent fully mechanized working face based on OLE for process control unified architecture(OPC UA) is proposed. According to the physical composition, functional modules and the information flow requirements between modules of intelligent fully mechanized working face, the information model architecture of intelligent fully mechanized working face is proposed by using object-oriented method. On the basis of this architecture, the physical objects and mining process data in fully mechanized working face are digitized and modeled to form a face-level information model. The static attribute set and process attribute set of basic component, monitoring component set and functional component set objects in information model are introduced in detail. The information model of the intelligent fully mechanized working face is instantiated by adopting the combined modeling mode of the OPC UA and the unified modeling language(UML). The UML class diagram is used to assist in the description of the information model structure, and then converted into the OPC UA information model XML description file. The information model structure data and attribute data are mapped to the OPC UA address space model, and the OPC UA server is started. The practical application results show that each system of fully mechanized working face can access the server address space, and successfully obtain the structure of intelligent fully mechanized working face information model and object data semantics, so as to complete the data collection, storage and update quickly. In order to verify the application effect of the information model, based on the OPC UA server, the information management and integrated analysis platform of fully mechanized working face is developed. The field application test show that the monitoring data displayed by the platform is consistent with the actual operation results (the background data are all from the address space information model), thus verifying the feasibility of the information model combined with the OPC UA protocol to realize the information interconnection of fully mechanized working face.
