摘　　要：数控设备作为现代数字化车间中核心制造装备,如何解决多种数控设备的联网问题,对于车间的统一管理,设备故障预警以及加工过程还原具有重要意义.通过对数控系统传统采集方式、基于适配器和代理的MTConnect标准和当前广泛流行的基于OPC UA通信协议的分析,基于OPC UA协议相比于其他技术更加的安全、可靠、中性.围绕OPC UA体系框架,本文设计了一种基于OPC UA标准架构的网络采集服务器.同时,为兼容多种采集方式,提出一种可扩展的OPC UA服务器架构,阐述了系统中模块间的通信方式.针对部分数控设备数据传输方式,运用了设计中间层作为中介的设计理念,进行了OPC UA服务器模块的设计.最后,在自主研发的数控系统和多家国内外著名厂商的数控系统上,对该模型进行了验证,证明了该模型的正确性和实用性.As the most important manufacturing equipment in the modern digital workshop,numerical control equipment can solve the problems of various equipment networking,which is of great significance to the unified management of the workshop,the early warning of equipment failure and the recovery of the processing process.Based on the analysis of the traditional acquisition method of CNC system,the MTConnect standard based on adapters and agents and the popular communication protocol based on OPC UA,the OPC UA protocol is more secure,reliable and neutral than other technologies.Based on the framework of OPC UA system,this paper designs a network acquisition server based on the architecture of OPC UA standard.At the same time,in order to be compatible with a variety of collection methods,an extensible OPC UA server architecture was proposed,and the communication mode between modules in the system was elaborated.Aiming at the data transmission mode of some numerical control devices,the design concept of designing the middle layer as the intermediary was applied to design the OPC UA server module.Finally,the model is verified on the self-developed CNC system and the CNC system of many famous manufacturers at home and abroad,and the correctness and practicability of the model are proved.
