基于实时信息驱动的制造过程可视化监控平台

摘要

针对目前由于缺乏有效的手段支持离散制造过程实时监控，导致生产车间透明程度低、信息流实时性差等问题，采用面向对象的方法构建制造资源本体模型(ROM)和一种支持生产系统实时监控的对象模型(IMPV)，并定义了 IMPV 的对象数据模型、可视化表征模型、对象操作模型和信息交互控制模型。在此基础上，设计并实现了一种支持制造过程实时可视化监控的体系架构，详细讨论了 IMPV的实例化方法以及基于规则映射的资源感知与信息集成模式，最后将该可视化监控系统应用于某发动机装配车间中，取得了良好的应用效果。%In order to deal with the low visibility for manufacturing processes,the time-lag effects of the information,and other problems,which were caused by the lack of the efficient measurements in the real-time monitoring of the discrete manufacturing process status,an object-oriented modeling ap-proach was adopted to establish the resource ontology model(ROM)and the interface model for man-ufacturing process visibility(IMPV).Further,the data model,the visualization model,the operation model and the information interface model of IMPV were proposed and defined.Based on that,a framework of the real-time visual monitoring for manufacturing processes was designed,and the in-stantiation method of IMPV and the information integration mode were discussed based on mapping rules.Finally,the results of the visual monitoring system’s applications on an engine assembly line demonstrate that the proposed system can improve the productivity and efficiency.
