摘　　要：在制造技术逐渐数字化、信息化与智能化的背景下,本文提出了一种基于开放平台通信统一架构(OPC UA)的多机系统互联互通的实现方法。首先,对3PRR并联机械系统与选择顺应性装配机器手臂(SCARA)机器系统建立了基于OPC UA的信息模型,实现了语义统一;然后,给出了一种基于OPC UA的多机系统互联互通的架构,并针对跨车间、跨局域网的问题,综合应用OPC UA和Web Service技术实现其互联互通;最后,搭建了相应的验证平台,并通过网页应用和第三方软件客户端验证了本文方法的有效性。Under the background that manufacturing technology is becoming digitalized, informationized and intelligent gradually, a method is proposed to implement the interoperability of multi-machine systems based on open platform communication unified architecture(OPC UA). Firstly, OPC UA based information models are established for 3PRR parallel mechanical system and selective compliance assembly robot arm(SCARA) machine system, which realize the semantic unification. Then an architecture based on OPC UA is presented to realize the interoperability of multi-machine system. To solve the problem of cross-workshop and cross-LAN between devices, OPC UA and Web Service technology are comprehensively used to realize its interoperability. Finally, a corresponding verification platform is built, and the effectiveness of this method is verified by a web application and a third-party software client.
