本发明实施例的一个方面能够达到的有益效果为:在本发明提供的高速列车需求元模型建立和处理方法和装置中,利用预先建立的高速列车结构树数据,依次选取高速列车结构树中的各结构点对应的需求项将其作为需求元模型中的需求对象,通过确定需求对象的需求属性以及属性关联信息构建需求元模型,使得建立的需求元模型与高速列车的结构具有对应关系。在具体构建、设计高速列车时,就可以通过调用各结构或组分对应的
需求元模型进行相应的设计、构建工作。由于高速列车的各结构、组件均具有对应的需求元模型,因此在设计高速列车时可以调用不同的需求元模型,无需重复设计、研发,因此大大减少了重复的研发工作,充分利用现有资源,提高研发效率,快速高效的完成快速列车的开发设计工作。

为了使本技术领域的人员更好地理解本发明中的技术方案,下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都应当属于本发明保护的范围。
本发明公开了一种高速列车需求元模型建立方法和装置,可以通过建立需求元模型对应各种需求数据,有效提高高速列车的开发效率,减少人力和资源浪费。
参见图1,为本发明实施例提供的一种高速列车需求元模型建立和处理方法流程示意图。
S101,获取预先建立的高速列车结构树的全集数据,所述高速列车结构树基于所述高速列车的结构建立得到,不同的高速列车类型对应不同的高速列车结构,不同的高速列车结构对应不同的高速列车结构树。
在本发明具体实现时,首先根据高速列车的结构,创建了高速列车结构树。不同的高速列车类型对应不同的高速列车结构,不同的高速列车结构对应不同的高速列车结构树。具体实现时,可以基于预先建立的结构树模板以及收集的不同车型的不同结构,动态的组建车型结构树实例,生成高速列车结构树数据库。当在创建具体的高速列车需求元模型时,首先获取所述高速列车对应的高速列车结构树全集数据。高速列车结构树可以通过高速列车的标识、类型或者名称检索得到。参见图2,为本发明实施例提供的高速列车结构树的一个示例示意图。高速列车结构树可以按照列车、车辆、组分(组份)、部件、子部件、零件等层级逐层构建,某一层级又包括不同的组成部分。列车为最高层级,车辆对应某一节或某几节车厢,组分(组份)又包括承载组份、走行组份或者车体组份等。某一组份又可以包括不同的部件层,部件层又可以包括子部件层等。例如,车辆01包括承载组份01、走行组份02,承载组份01又包括车体结构01、头型结构02、车体断面03、车体附件结构04等。每一部件层又可以包括不同的子部件,具体如图2所示。当然,也可以根据其他方式构建高速列车结构树,本发明对此不进行限定,只要构建的高速列车结构树能与高速列车的结构对应即可。
S102,利用所述预先建立的高速列车结构树的全集数据,依次选取所述高速列车结构树中的各结构点对应的需求项,将所述需求项确定为需求元模型的需求对象。
在本发明中,需求元模型又可以称之为需求数据元模型,用于表示需求数据的模型。
在本发明具体实现时,构建需求元模型时,需求元模型包括需求对象、对象属性(又可称之为需求属性)、属性关联信息(又可称为关系)3个元
素。
具体实现时,可以采用三元组表示高速列车需求元模型(RMM):
RMM={<Object><Property><Association>}
其中,<Object>表示需求对象、<Property>表示对象属性、<Association>表示属性关联信息。
具体实现时,如图2所示,可以将高速列车结构树中的各结构点对应的需求项确定为需求元模型中的需求对象。其中,需求对象可以包括列车、车辆、组分、部件、子部件、零件中的一种或多种。
具体实现时,需求对象可以表示高速列车不同层次的设计对象,包括了产品、组件、零件等,即高速列车产品结构不同层级的描述。具体可以表示为:
<Object>=<Product>|<Assembly>|<Part>
其中,<Product>表示产品、Assembly表示组件,Part表示零件。
在一种可能的实现方式中,所述依次选取所述高速列车结构树中的各结构点对应的需求项,将所述需求项确定为需求元模型的需求对象包括:按照需求元模型元类、需求元模型类、需求元模型实例的层级顺序依次选取所述高速列车结构树中的各结构点对应的需求项,将所述需求项确定为需求元模型的需求对象。其中,所述需求元模型元类用于描述设计模型中的基本组件;所述需求元模型类用于描述与具体物理对象相关联的模型,由所述需求元模型元类赋值得到;所述需求元模型实例用于描述具体设计对象,由所述需求元模型类赋值得到。
S103,确定所述需求元模型的各需求对象的对象属性以及属性关联信息;其中,所述对象属性包括主体属性、关键属性、旅客属性、质量约束属性中的一种或多种;所述属性关联信息包括隶属关系、包含关系、拥有关系中的一种或多种。
前面提到,在构建需求元模型时,需要确定3个元素:需求对象、对象属性以及属性关联信息。在确定需求对象后,即需要确定各需求对象的对象属性以及属性关联信息。
其中,对象属性参数集合可以包含高速列车不同产品层次的相关的需
求属性,具体可以包括主体属性、关键属性、旅客属性、质量约束属性中的一种或多种。其中,主体需求属性包括路网属性、环境属性);关键需求属性主要对应性能属性、结构属性;旅客需求属性可以包括功能属性、性能属性、约束属性;质量约束属性(英文全称为Total Quality Control,英文缩写为TQC)属性可以包括质量、交货期、过程、服务人员等属性要求。
对象属性具体可以用下式表示:
<Property>=<主体属性>|<关键属性>|<旅客属性>
对象属性参数的描述由属性标识id、参数名t、参数类型a、参数值v四元组组成,可以描述为Property={id,t,a,v}。
其中,属性关联信息又可以称为关系信息用于描述对象属性之间的各种关系信息,主要包括各设计对象之间,即高速列车产品层级对象之间关系、各属性之间的关系以及设计对象与属性之间的关联关系。关联关系信息集合可以定义为一个4元组(a_id,a_role,a_property,a_operation)其中a_id为关联向量的标识,a_role为关联角色集合,即与该关联涉及的对象实例或属性的标识,a_property为关联自身的属性,a_operation为对关联属性进行操作的方法集。
具体地,关联关系可以包括以下任意一种或多种关系:
(1)隶属关系:部件属于某个产品,即产品结构中下层结构隶属于上层结构,语义含义为“隶属”。例如,部件属于某个产品,即产品结构中下层结构隶属于上层结构,语义含义为“隶属”。车辆隶属于列车、走行组份隶属于车辆、承载组份隶属于车辆、动力组份隶属于车辆、其它组份隶属于车辆。
(2)包含关系:产品包含某些部件,即上层结构包含下层层级,语义含义为“包含”。产品包含某些部件,即产品上层结构包含下层结构,语义含义为“包含”。列车包含车辆、车辆包含走行组份、车辆包含承载组份、车辆包含动力组份、车辆包含其它组份。
(3)拥有关系:对象拥有属性的关系,语义含义为“拥有”。
其中,关联关系还可以包括对象与对象之间的关系、对象与属性之间的关系、属性与属性之间的关系,具体可以根据需要灵活设置。
S104,根据各所述需求对象的对象属性以及属性关联信息建立需求元模型。
参见图3,为本发明实施例提供的需求元模型视图的一个实例示意图。产品为需求对象,其可以拥有属性(has property),即需求属性;其还可以具有关系(has Association),即关联信息。其中,需求属性也可以具有关系(has Association),即关联信息。需求属性可以包括主体需求属性、关键需求属性、旅客需求属性等。其中,主体需求属性又可以包括路网、环境属性;关键需求属性又可以包括结构属性、性能属性。产品可以具有或者包含部件(has Assembly),部件可以具有或者包含零件(has Part)。当然,产品也可以具有或者包含零件(has Part)。
前面提到,高速列车需求元模型定义分为三个层次,需求元类、需求类以及需求实例,元类描述设计模型中使用的基本组件;类用来描述与具体物理对象相关的设计模型;实例则对应具体的设计对象,是用户对设计对象的实现,实例是类的一个赋值实现。
其中,在构建需求元模型时,也是按照需求元模型元类、需求元模型类、需求元模型实例的层级顺序依次选取需求对象,逐步根据所述需求对象的对象属性以及属性关联信息建立需求元模型的。具体实现时,需求元模型通过赋值的操作,逐步由需求元类赋值生成需求类,再由需求类赋值最终形成高速列车需求实例,具体赋值过程如图4所示。元类通过赋值得到类,类通过赋值得到实例。图4所示为需求元模型赋值的一个示例。
其中,需求元模型元类即列车/车辆需求元模型元类是需求元模型的基础层以及最低层,为需求元模型类提供数据基础。是囊括了所有与高速列车相关的所有需求数据集合,其基于元模型的描述和格式,所包含的数据包括对象数据、需求属性数据以及关系数据。其中:对象数据是指高速列车所包含的所有相关的产品结构数据,并且之间不存在具体的层级关系,所有结构在需求元模型元类中都是独立存在的数据项。属性数据是指与高速列车相关的所有用户需求项的数据集合,所有的需求项按照不同的分类属性进行分类,即按照主体需求、关键需求、旅客需求划分。
其中,需求元模型类是需求元模型的第二层,需求元模型类的构建过
程是通过需求元模型元类通过赋值实例化后得到的针对单一对象,基于元模型的描述和格式,其所包含的数据包括对象数据、需求属性数据以及关系数据。其中:对象数据,描述的是单一的对象,通过对元类赋值得到。需求属性数据,包含了所有与单一对象相关的需求项数据,并且也分为了主体需求(路网需求、环境需求)、关键需求、旅客需求等。关系数据,主要描述了与对象相关的关系数据。
参见图5,为本发明实施例提供的列车级元模型示意图。在图5中,按照需求对象、属性、关系3部分构建了需求元模型。参见图6,为本发明实施例提供的走行组份需求元模型示意图。其中,描述了走行组份的需求元模型,包括对象、属性、关系3个部分。关系又可以包括对象-对象关系、属性-属性关系、对象-属性关系。具体参见图6。
S105,将建立的各需求元模型保存在数据库中构成需求元模型数据库,所述需求元模型数据库用于当接收到调用所述需求元模型的指令时,响应调用所述需求元模型的指令输出对应的需求元模型数据以构建高速列车各结构。
具体实现时,根据建立好的各需求元模型构建需求元模型数据库。当在进行高速列车的具体设计开发时,可以调用所述需求元模型数据库获得相应的需求元模型数据以构建高速列车各结构。
