基于OPCUA的3D实时监控系统设计与实现

Design and Implementation of 3D Monitoring System Based on OPC UA

为实现智能制造系统的闭环反馈,对生产过程进行实时智能监控管理是一个核心环节。针对生产过程监控的实时性、异构设备数据传输的通用性、生产监控移动性的要求,开发了基于OPC UA(OPC Unified Architecture)的服务端,建立了生产系统监控场景的3D统一表达模型,并通过3D模型轻量化技术和生产系统场景模型动态调度技术,基于开源图形引擎分别在windows和android平台上开发了3D监控客户端,实现了对于生产过程中各个设备参数的实时数据通信和生产过程的实时仿真。通过机器人焊接工厂的案例表明,该系统可以直观实时监控生产过程。

With the rapid development of industrial automation, users＇ demands on the safety of data collection, data transmission and data interaction during manufacturing process are increasing, along with which is the serious communication problem because of device heterogeneity. Besides, due to the rapid expansion of mobile application, more and more mobile devices such as mobiles and Pads are pouring into monitoring system. In this paper, a 3D monitoring system based on OPC UA is designed and implemented to meet the requirement of real-time and versatility of devices. The 3D monitoring system is composed of an OPC UA server and an OPA UA client, which is developed with 3D virtual reality technology with open source image engine osg both on computer and Android Pad. The real-time data communication and production process simulation of each equipment parameter during manufacturing process are realized. A case study of welding factory shows that the 3D monitoring system can monitor the manufacturing process vividly and in real time.
