基于时空动态知识图谱的明渠实时调度模式智能识别研究
Intelligent identification of real-time regulation pattern in open channels based on spatiotemporal dynamic knowledge graph
摘要
Abstract
Based on the hydraulic characteristics of open channels and the actual demand of engineering projects,real-time pattern recognition for intelligent regulation can provide decision-making support for engineering manage-ment,thus enhancing the intelligent level of water transfer projects.This study,aiming at the problem of low effi-ciency in regulation pattern recognition due to the numerous related elements,complex relationships,and strong time-varying nature of real-time open channel regulation,constructs a knowledge graph that describes the spatiotem-poral dynamic changes of the hydraulic characteristics of open channels,using the Wangnou-Ruwugou river section of the Jiaodong Water Transfer Project as an example.Firstly,HEC-RAS software was utilized for historical scenario simulation analysis to obtain prior knowledge,such as optimal initial gate opening values and gate opening adjust-ment trends under different regulation patterns that meet their respective regulation objectives.Then,based on the Density-Based Spatial Clustering of Applications with Noise-Random Forest(DBSCAN-RF)classification algo-rithm,historical scenario classification analysis was conducted to obtain a labeled classification sample set.Finally,the Neo4j graph database was used to structurally store historical scenario characteristics and simulation and classifi-cation knowledge,forming a spatiotemporal dynamic atlas,ultimately achieving intelligent recognition of real-time scheduling patterns for open channels.关键词
