IFC标准铁路四电工程信息模型数据存储标准1 总则1.1 编制原则本标准的编制遵循以下原则:(1)兼容性原则。本标准与buildingSMART组织已发布的IFC(Industry Foundation Class)标准保持最大限度的兼容。(2)可移植性原则。本标准仅规范铁路四电工程领域的基础数据模型。该数据模型中的元素可以被不同技术平台的不同编码方式使用。(3)抽象性原则。本标准仅定义在国内外广泛应用,且被整个领域共同认知与接受的重要铁路四电工程元素,以使本标准的固定模型最小化。(4)可扩展性原则。本标准可与具体的信息分类、编码、字典相结合、对本标准定义的元素进行进一步“修饰”或限度,而不扩大和改变元素的基本含义,从而满足特定用户的信息存储与交换需求。(5)可选择性原则。本标准中定义的任何元素在信息存储与交换需求中都是可选的。(6)可重复性原则。本标准中定义的任何元素在数据交换与存储的应用中都是可重复的。(7)易用性原则。本标准提供标准作者之间、作者与软件开发人员之间描述标准的形式化文件与可读性文件,从而不给相关人员增加过多的工作负担。1.2 编制范围本标准目前涵盖铁路通信、信号、电力变电、接触网专业领域。1.3 适用范围本标准适用于铁路工程BIM实施标准制定、铁路BIM软件研发和铁路BIM应用研究。1.4 引用规范本标准引用以下标准和规范:GB/T 16656.1—2008工业自动化系统与集成产品数据表达与交换第1部分:概述与基本原理(ISO 10303—1:1994)。GB/T 16656.11—2010工业自动化系统与集成产品数据表达与交换第11部分:描述方法:EXPRESS语言参考手册(ISO 10303—11:2004)。GB/T 16656.21—2008工业自动化系统与集成产品数据表达与交换第21部分:实现方法:交换文件结构的纯正文编码(ISO 10303—21:2002)。ISO 16739:2013工业基础类平台规范。buildingSMART Industry Foundation Classes IFC4x1。2 术语和缩略语2.1 术语下列术语适用于本标准:182016年第5期

IFC实体(entity):表示具有共同特性的概念或物理对象的一类集合。属性(attribute):对实体特性的抽象描述。直接属性(direct attribute):对实体特征进行直接描述的信息单元。标准反向属性(inverse attribute):定义获取关联实体的信息单元,以保证参照完整性。衍生属性(derived attribute):从其他属性计算得到的信息单元。属性集(property set):属性的集合。模式(schema):构造部分或全部模型的数据项的集合。信息模型(information model):某领域概念及关系的一种抽象的数据语言表达。空间结构单元(spatial structure element):通常表示物体的空间主体及其主要组成结构。空间组成(spatial composition):指空间结构单元之间部分与整体间的组成关系。空间分解(spatial decomposition):指空间结构单元间整体与部分间的分解关系。空间包含(spatial containment):指空间结构单元包含实体的关系。被空间包含(contained in spatial structure):指实体被空间结构单元包含的关系。实体组成(entity composition):指组合件包含实体的关系。Express-G:EXPRESS语言的图形子集,用图形化的方法描述概念与概念之间的关系。2.2 缩略语下列缩略语适用于本标准。AEC/FM:Architecture,Engineering,Construction and Facilities Management/建筑、设计、施工和设备管理。BIM:Building Information Modeling/建筑信息模型。IFC:Industry Foundation Classes/工业基础类。HVAC:Heating,Ventilation and Air Conditioning/暖通空调。XML:Extensible Markup Language/可扩展标记语言。3 铁路四电工程信息模型基础数据体系结构3.1 铁路四电工程信息模型基础数据体系结构铁路四电工程信息模型基础数据体系结构是在IFC4和铁路工程信息模型数据存储标准1.0版的基础上,根据铁路四电工程的特点及需求进行扩展。为了维持IFC标准的可延续性,在扩充过程中遵循了以下扩展原则:(1)四电专业在领域层、共享层做扩展,不增加新领域。(2)主要利用既有实体进行扩展。(3)主要通过增加属性或预定义类型来扩充实体。(4)当以上两点都不能满足需要时,增加新实体,并增加相应的通用属性类。根据上述原则进行扩展,如图3.1所示。在资源层(Resource Layer)、核心层(Core Layer)没有扩展。在领域层(Domain Layer)的电气领域(Electrical Domain)和建筑控制领域(Building Controls Domain)、共享层(Interop

Layer)根据四电专业特点新增和扩展了一些实体。3.2 铁路四电工程空间结构组成铁路四电工程空间结构组成如图3.2所示。在铁路车站(IfcRailwayStation)下面包含多个配送系统(IfcDistributionSystem)。配送系统可以是通信、信号、接触网、电力或者变电系统。图3.3是IFC4中一个配电系统的电路图,铁路四电系统基本上和该系统类似。一个配送系统(IfcDistributionSystem)通过IfcRelAggregates包含多个子配送系统,配送系统内部通过IfcRelAssignsToGroup包含多个设备、接线盒和线缆,设备和线缆通过IfcRelNests包含多个端口;端口之间通过IfcRelConnectsPorts关联。2016年第5期19

IFC标准铁路四电工程信息模型数据存储标准1 总则1.1 编制原则本标准的编制遵循以下原则:(1)兼容性原则。本标准与buildingSMART组织已发布的IFC(Industry Foundation Class)标准保持最大限度的兼容。(2)可移植性原则。本标准仅规范铁路四电工程领域的基础数据模型。该数据模型中的元素可以被不同技术平台的不同编码方式使用。(3)抽象性原则。本标准仅定义在国内外广泛应用,且被整个领域共同认知与接受的重要铁路四电工程元素,以使本标准的固定模型最小化。(4)可扩展性原则。本标准可与具体的信息分类、编码、字典相结合、对本标准定义的元素进行进一步“修饰”或限度,而不扩大和改变元素的基本含义,从而满足特定用户的信息存储与交换需求。(5)可选择性原则。本标准中定义的任何元素在信息存储与交换需求中都是可选的。(6)可重复性原则。本标准中定义的任何元素在数据交换与存储的应用中都是可重复的。(7)易用性原则。本标准提供标准作者之间、作者与软件开发人员之间描述标准的形式化文件与可读性文件,从而不给相关人员增加过多的工作负担。1.2 编制范围本标准目前涵盖铁路通信、信号、电力变电、接触网专业领域。1.3 适用范围本标准适用于铁路工程BIM实施标准制定、铁路BIM软件研发和铁路BIM应用研究。1.4 引用规范本标准引用以下标准和规范:GB/T 16656.1—2008工业自动化系统与集成产品数据表达与交换第1部分:概述与基本原理(ISO 10303—1:1994)。GB/T 16656.11—2010工业自动化系统与集成产品数据表达与交换第11部分:描述方法:EXPRESS语言参考手册(ISO 10303—11:2004)。GB/T 16656.21—2008工业自动化系统与集成产品数据表达与交换第21部分:实现方法:交换文件结构的纯正文编码(ISO 10303—21:2002)。ISO 16739:2013工业基础类平台规范。buildingSMART Industry Foundation Classes IFC4x1。2 术语和缩略语2.1 术语下列术语适用于本标准:182016年第5期

IFC实体(entity):表示具有共同特性的概念或物理对象的一类集合。属性(attribute):对实体特性的抽象描述。直接属性(direct attribute):对实体特征进行直接描述的信息单元。标准反向属性(inverse attribute):定义获取关联实体的信息单元,以保证参照完整性。衍生属性(derived attribute):从其他属性计算得到的信息单元。属性集(property set):属性的集合。模式(schema):构造部分或全部模型的数据项的集合。信息模型(information model):某领域概念及关系的一种抽象的数据语言表达。空间结构单元(spatial structure element):通常表示物体的空间主体及其主要组成结构。空间组成(spatial composition):指空间结构单元之间部分与整体间的组成关系。空间分解(spatial decomposition):指空间结构单元间整体与部分间的分解关系。空间包含(spatial containment):指空间结构单元包含实体的关系。被空间包含(contained in spatial structure):指实体被空间结构单元包含的关系。实体组成(entity composition):指组合件包含实体的关系。Express-G:EXPRESS语言的图形子集,用图形化的方法描述概念与概念之间的关系。2.2 缩略语下列缩略语适用于本标准。AEC/FM:Architecture,Engineering,Construction and Facilities Management/建筑、设计、施工和设备管理。BIM:Building Information Modeling/建筑信息模型。IFC:Industry Foundation Classes/工业基础类。HVAC:Heating,Ventilation and Air Conditioning/暖通空调。XML:Extensible Markup Language/可扩展标记语言。3 铁路四电工程信息模型基础数据体系结构3.1 铁路四电工程信息模型基础数据体系结构铁路四电工程信息模型基础数据体系结构是在IFC4和铁路工程信息模型数据存储标准1.0版的基础上,根据铁路四电工程的特点及需求进行扩展。为了维持IFC标准的可延续性,在扩充过程中遵循了以下扩展原则:(1)四电专业在领域层、共享层做扩展,不增加新领域。(2)主要利用既有实体进行扩展。(3)主要通过增加属性或预定义类型来扩充实体。(4)当以上两点都不能满足需要时,增加新实体,并增加相应的通用属性类。根据上述原则进行扩展,如图3.1所示。在资源层(Resource Layer)、核心层(Core Layer)没有扩展。在领域层(Domain Layer)的电气领域(Electrical Domain)和建筑控制领域(Building Controls Domain)、共享层(Interop

Layer)根据四电专业特点新增和扩展了一些实体。3.2 铁路四电工程空间结构组成铁路四电工程空间结构组成如图3.2所示。在铁路车站(IfcRailwayStation)下面包含多个配送系统(IfcDistributionSystem)。配送系统可以是通信、信号、接触网、电力或者变电系统。图3.3是IFC4中一个配电系统的电路图,铁路四电系统基本上和该系统类似。一个配送系统(IfcDistributionSystem)通过IfcRelAggregates包含多个子配送系统,配送系统内部通过IfcRelAssignsToGroup包含多个设备、接线盒和线缆,设备和线缆通过IfcRelNests包含多个端口;端口之间通过IfcRelConnectsPorts关联。2016年第5期19
