基于OPC UA的纺织智能染整车间信息模型研究与实现

为建立纺织染整行业智能染整车间系统,提出了一种基于OPC UA的信息系统建模方案。以平幅连续生产车间为例,在分析重点设备的物理模型的基础上,抽象出“染整设备类型”和“监控单元类型”,用于设备和监控单元公共的属性及控制方法的定义,同时通过各类设备的私有属性定义其特有的性质。模型定义符合OPC UA国际标准,设备能对外提供规范的服务,呈现统一接口和通信规范,实现了设备和系统间的互联互通。在建立设备模型的基础上,搭建了纺织智能染整车间的逻辑模型和整体架构,采用OPC UA通信规范,实现了设备端与制造执行系统的数据通信。该模型和车间架构在实际生产中的应用,为OPC UA技术在纺织行业的应用进行了探索和实践。

Research and implementation of information model for textile intelligent dyeing and finishing workshop based on OPC UA

In order to establish a system of intelligent dyeing and finishing workshop in textile dyeing and finishing industry,an information system modeling scheme based on OPC UA was proposed. Taking the flat continuous production workshop as an example,the " dyeing and finishing equipment type" and "monitoring unit type" were abstracted on the basis of analyzing the physical model of the key equipment,which were used to define the common attributes,control methods of the equipment and monitoring unit,and unique properties through the private properties of various devices. The model definition fully complies with the OPC UA international standard,enabling the device to provide standardized services to the outside,presenting a unified interface and communication protocal,and achieving interconnection and interoperability between devices and systems. On the basis of establishing the equipment model,the logical model and overall architecture of the textile intelligent dyeing and finishing workshop were built.The data communication between the equipment end and the manufacturing execution system was implemented by using the OPC UA communication protocol. The model and workshop architecture have been applied in actual production,providing important references to use of OPC UA technology in the whole textile industry.
