地下矿可视化生产管控系统参数化数据模型

在融合面向实体的数据模型和网络数据模型的基础上,引入参数对象,设计一种网络化、层次化、参数化的实体与网络复合模型(PENDM),解决该系统中RPS的空间数据建模问题,形成以井巷为空间参照的井巷与生产系统整体模型.运用面向对象的思想建立PENDM的主要数据结构.PENDM采用面向实体的元素描述井巷工程和生产系统的实体特征,采用网络元素描述系统内部网络的空间拓扑结构,采用参数描述实体轮廓、定位信息、设备信息和其他附属信息.结合具体应用分析PENDM在地下矿山生产管控系统中的作用.研究结果表明:该模型能够实现复杂生产系统信息管理、空间分析和三维体模型的自动建立,解决了矿山井巷工程与生产系统的表达、自动建模与快速更新以及漫游路径和救避灾路线的求解问题,对于其他(如通风量计算)的需要网络的专业分析同样有效.

Parametric data model for underground mine 3D visual production management and control system

In order to establish the spatial data model of the RPS for the UM3DVPMCS,a new networked,hierarchical,hybrid and parametric entity-network data model(PENDM) was designed,which integrates entity-oriented data model and network data model and has some parameter elements.When the PENDM was used to describe roadways and production systems,a roadways and production systems frame model(RPSFM) was formed.The object-oriented data structures of the PENDM were given.The PENDM describes the features of RPS with entity-oriented elements and the spatial topological relationships of inner network with network elements.It defines the entity outline,device information and other additional informations with parameters.Finally,the model was applied in the underground mine 3D visual production management and control system(UM3DVPMCS),and some applications were analyzed.The results show that the model is suitable for information management of complex production systems,spatial analysis,and automatic modeling of three-dimensional volume models,and solves the problems of the expression: Automatic modeling and rapid renewal of roadways and production systems and obtaining the roaming path and escape route.It is also effective to solve the other professional analysis problems(such as ventilation calculation) which need network.
