摘要
介绍数据校正技术的基本原理,并以某石化企业为背景,分析数据校正系统的总体结构和功能模块。经校正的物流平衡数据可支持MES层中的多项应用,达到了很好的应用效果。
Beginning with the three layers model (ERP/MES/PCS) of CIMS in process industry,the method,structure and components of data reconcillation system are analyzed.On the background of some chemical plant,the mass-flow data are reconciliated with the method,and the material balance results are used to support some application of MES layer.A study case of the material balance system is given in a petrochemical plant.
