摘　　要： 制造设备间的广泛互联、互操作是制造领域实现广泛物联的重要前提.对数控系统进行实时监测,收集数控系统加工参数、刀具几何参数、零件质量检测等异构数据,进行有效地关联监控是目前研究的热点.基于OPC(object linking and embedding for process control)UA(unified architecture)连接数控系统,建立基于MTConnect的"适配器-代理(adapter-agent)"通用数控系统实时监控体系.研究实时监控数据模型、通信框架及其访问策略,给出了机床加工过程监控数据的标准数据模型.开发的原型系统在某航空薄壁件的实际加工过程进行实时监控,实现了加工过程数据、离线数据的综合可视化表达,验证了所提出的数控系统信息集成方法的有效性.该方法构建的数据模型清晰地表达了各加工要素,具有很好的可扩展性. Extensive interconnection and interoperability among manufacturing equipment are an important prerequisite for the realization of extensive association. It is the focus of the current research to monitor the NC（numerical control） system in real time, and collect the relevant processing data of the NC system, the geometric parameters of the cutting tools and the quality of the parts. NC system is connected via OPC（object linking and embedding for process control） UA（unified architecture）. Then, the real-time monitoring system of ＂Adapter-Agent＂ universal CNC（computer numerical control） system based on MTConnect is established. The real-time monitoring data model, communication framework and access strategy are studied. Meanwhile, a prototype system is developed for real-time monitoring in the actual process of a thin-wall part of aircraft. The system can implement the processing data and off-line data integrated visual expression, and verify the validity of the information integration method of CNC system of the proposed data model, the scalable model can implement a clear expression of the processing elements.
