地下矿可视化管控系统空间数据模型

摘要

为了满足地下矿可视化管控系统可视化表达、空间分析、自动化建模与模型动态更新功能的需要,分析了矿山空间现象的特征与典型的三维空间数据模型,据此设计了一种包含三维骨架模型、顾及拓扑面向实体的三维矢量空间数据模型( TEVDM)和八叉树块段模型(OBM)的混合时空数据模型.该模型利用TEVDM和OBM表达空间实体的精确边界和内部属性,引入网络化、层次化、参数化的实体与网络复合模型(PENDM)来描述并巷工程与生产系统的骨架,引入行为模型描述具有行为特征的人员和设备,利用复杂要素对具有完整语义的要素集合体进行描述.最后给出了用该模型描述矿山空间现象和进行空间分析应用的示例,表明该模型比传统模型在矿山领域具有更好的实用性.%In order to realize the visualization, spatial analysis, automatic modeling and dynamic updating of model, the mine spatial environment and traditional 3D spatial data models were analyzed. Then an entity-oriented spatio-temporal hybrid data model was designed. It integrated the 3D parameter skeleton model, Topology-concerned and Entity-oriented 3D Vector Data Model (TEVDM) and Octree-Block Model ( OBM). The TEVDM and OBM were used to express the boundary and internal property of orebodys. The Parametric Entity-Network Data Model (PENDM) was introduced into the model to describe the skeleton of the roadway engineering and production systems. Particularly, a behavior model was introduced into the model to describe the personnel and devices with behavior characteristics. The model also included the complete spatial feature which could describe the set of semantically related entities. Finally, some samples of using this model were given to describe the mines' spatial phenomenon and carry out spatial analysis. The samples show this model has better practicability in mining than traditional models.
