背景技术
在工业领域,为了更加方便地对工业生产活动进行监管,对生产环节中包含的人、机、料、法、环等五要素进行数字孪生,已然是不可阻挡的发展大潮。然而,现有的对这些要素进行数字孪生的技术通常缺少专门的对其历史状态的数字孪生理论和技术。
因此,如何实现对目标对象的历史状态的数字孪生,是一个亟需解决的问题。

具体实施方式
下面通过附图以及具体实施例对本申请技术方案做详细的说明,应当理解本申请实施例以及实施例中的具体特征是对本申请技术方案的详细的说明,而不是对本申请技术方案的限定,在不冲突的情况下,本申请实施例以及实施例中的技术特征可以相互组合。
需要理解的是,在本申请实施例的描述中,“第一”、“第二”等词汇,仅用于区分描述的目的,而不能理解为指示或暗示相对重要性,也不能理解为指示或暗示顺序。在本申请实施例的描述中“多个”,是指两个或两个以上。
本申请实施例中的术语“和/或”,仅仅是一种描述关联对象的第一关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。另外,本文中字符“/”,一般表示前后关联对象是一种“或”的关系。
在数字孪生领域,可以将客观世界各种对象的历史状态孪生成对象的历史数据。例如,实体物具有空间的性质,该性质可以通过几何形状以及集合位置来进行标识,而实体物各个过去时刻的空间信息以及自身其它属性可以用于表示实体物的历史状态。将这些信息孪生成统一的数据结构就是对实体物历史状态的数字孪生。又例如,当需要对客观世界中发生的各种事件进行数字孪生时,可以将客观世界中的事件的历史状态孪生成事件对应的历史数据,而历史数据中各个过去时间的各种属性,可以被用来标识事件的历史状态。并且,不同的事件之间存在着内置的关联关系,这些关联关系也可以对其进行数字孪生,以实现对事件孪生后的数据更有效的管理。
基于以上思路,本申请提供一种孪生目标对象的历史状态的方法。
参见图1,为本申请实施例提供的一种孪生目标对象的历史状态的方法的流程图,该方法的执行主体可以是具有计算功能的各类设备,例如笔记本电脑、台式计算机以及服务器等等,也可以是各类移动终端设备,例如手机、平台以及其它可以实现计算功能的终端设备等。应理解,上述设备仅为举例说明,本申请不做限制。该方法具体步骤如下:
步骤S101:针对目标对象以及附属于该目标对象的至少一个子对象,分别建立目标对象模型以及至少一个子对象模型。
其中,上述目标对象可以包括第一目标实体物或者目标事件。进一步地,当目标对象包括第一目标实体物时,其对应的子对象包括子实体物,而当目标对象包括目标事件时,其对应的子对象则包括子事件。
针对上述不同的目标对象与子对象的组合,以下将分别介绍第一目标实体物与子实体物、目标事件与子事件的附属关系:
其一,第一目标实体物与子实体物之间的附属关系可以是整体与部分的关系,也可以是包含与被包含的关系。例如,第一目标实体物指的可以是车间甲,而附属于该第一目标实体物的子实体物则可以是该车间甲中的机器1、机器2、机器3等,体现第一目标实体物与子实体物之间包含与被包含的关系。又例如,第一目标实体物可以指的是某一卡车,而该第一目标实体物对应的子实体物则是卡车所牵引的半挂车、车头、轮胎等,体现目标实体物与子实体物之间整体与部分的关系。
而当目标对象包括第一目标实体物时,针对目标对象对应创建的目标对象模型也可以称为第一目标实体物模型,针对子对象对应创建的子对象模型也可以称为子实体物模型。
其二,目标事件与子事件之间的附属关系则可以是属于关系,换言之,目标事件与至少一个子事件之间存在概念上的整体与部分的关系。例如,假设目标事件为请假事件,而作为一个整体的该请假事件可以拆分为几个不同的子事件,例如:子事件1:请假人发起请假申请,子事件2:部门主管审批请假申请,子事件3:经理审批请假申请。因此,从概念上来说,这三个子事件均为目标事件的附属事件。
相应的,当目标对象包括目标事件时,针对目标对象对应创建的目标对象模型也可以称为目标事件模型,针对 子对象对应创建的子对象模型也可以称为子事件模型。
以上即为目标对象包含不同种类的对象时,这些对象之间的附属关系的含义。而对于本申请实施例提出的方案而言,目标对象模型对应于上述的目标对象,用于描述目标对象的历史状态;至少一个子对象模型对应于上述至少一个子对象,用于描述至少一个子对象的历史状态。其中,这些各个对象模型中,均包括时间属性,用于描述对象模型中的数据对应的时间。
需要说明的是,被创建的各个对象型的存在形式可以包括不同种类。例如,既可以是由数据表的形式保存在数据中,也可以是由图像的形式进行保存,还可以是由其他可能的数据保存形式进行存储,本申请不做限制。
步骤S102:将目标对象模型与至少一个子对象模型中的时间属性的取值设置为第一历史时间,第一历史时间用于指示目标对象模型与至少一个子对象模型中数据对应的时间。
可选的,各类对象模型中,时间属性是用于描述对象模型中的历史数据对应的时间。
示例性的,对于实体物模型而言,时间属性是用于描述实体物模型中的历史数据对应的时间。例如,对于车间甲而言,其对应的对象模型的第一条历史数据可能是车间甲投入使用的记录,而该记录对应的时间即为车间甲投入使用的时间,此时,该记录对应的时间属性的取值可能是:2020年1月1日。又例如,车间甲对应的模型中的某一条数据表示的是车间甲中出现了一台新机器,因此,该记录所对应的时间属性的取值则可能是:2020年6月1日。
而对于事件模型而言,时间属性则可以是用于描述各个事件发生或持续的时间。例如,假设目标事件为请假事件时,其对应的事件模型中的时间属性可以是该请假事件从发起请求到结束审批的全过程的时间,如:2020年1月1日-2020年1月2日。又例如,至少一个子事件中的子事件1(请假人发起请假申请)这一事件对应的事件模型的时间属性的取值可以是2020年1月1日10:00-2020年1月1日-12:00。
这样,用户可以通过这些对象模型中的时间属性,获知各个历史数据对应的时间,从而更清晰的获取对象模型对应的对象的历史状态以及其对应的信息,加强了对各类目标对象的信息的管理。
可选的,上述第一历史时间可以是当前时刻之前的至少一个时刻或是当前时刻之前的至少一个持续时间段。
示例性的,当目标对象模型是针对上述车间甲创建而成时,上述记录车间甲投入使用的历史数据对应的第一历史时间可以被记录为2020年1月1日的某一时刻,也可以被记录为1月1日这一整个持续时间段。具体历史数据选择哪一种第一历史时间进行记录,可以根据实际需求选择,本申请不做限定。
而当目标对象模型是针对目标事件进行创建时,在上述关联至目标对象模型的子对象模型中,其时间属性的值在目标对象模型中时间属性的值的范围内。
示例性的,参见图2,为本申请实施例提供的目标事件与子事件时间范围的示意图。从图2中可以看到,目标事件的从开始时刻到结束时刻所持续的时间,覆盖了子事件1、子事件2以及子事件3所持续的时间。
可选的,各类对象模型中还可以包括数据时间属性,该数据时间属性用于描述对象模型中的历史数据被记录或是被修改的时间。
示例性的,以上述车间甲的第一条历史数据为例进行说明。虽然车间甲的该条历史数据对应的时间属性表明该车间是于2020年1月1日投入使用的,但是,由于对象模型的创建发生在2022年1月1日,因此,该条历史数据对应的数据时间属性的取值即为2022年1月1日。以上述请假事件为例进行说明则是:虽然该对象模型的时间属性的取值可能是2020年1月1日-2020年1月2日,但是,对象模型的创建时间可能较事件发生的时间(例如2020年2月1日)推迟很多,因此,对于对象模型中的数据时间属性,其取值即为2020年2月1日。
另外,对于某些历史数据,可能出现错误修订的情况,例如某次错误勘定时,发现模型中的一条历史数据中的数值存在错误,可以对其进行修改,并且,此时该条历史数据对应的数据时间属性的取值也会及时更新,用以表示该条历史数据的最新修订时间。
在本方式中,通过数据时间属性,可以更加准确地向用户展示历史数据,并展示历史数据的更新情况,提高了用户精细化管理对象信息的程度。
步骤S103:建立目标对象模型与至少一个子对象模型的第一关联关系,第一关联关系用于将至少一个子对象模型关联至目标对象模型。
具体的,针对现实中,目标对象与至少一个子对象存在的关联关系,建立目标对象模型与至少一个子对象模型的第一关联关系,该第一关联关系用于将上述至少一个子对象模型关联到目标对象模型。
示例性的,为了便于明晰上述第一关联关系的含义,以下将分别针对实体物与事件,对上述第一关联关系进行 介绍。
参见图3,为本申请实施例提供的一种可能的实体物之间关联关系的示意图。在图3中,存在车间甲以及包含在车间甲中的机器1、机器2、机器3,假设以车间甲为目标实体物,那么,在创建实体物模型后,可以根据车间甲与机器1、2、3之间的包含与被包含的关系,建立车间甲对应的目标实体物模型与机器1、2、3对应的子实体物模型1、2、3之间的第一关联关系,该第一关联关系用于将子实体物模型1、2、3关联到目标实体物模型上。
对于现实中的事件而言,以上述请假事件为例,该请假事件可以被拆分为三个子事件,因此,对于针对上述请假事件以及三个子事件创建完成的目标对象模型以及三个子对象模型而言,可以根据请假事件与三个子事件整体与部分的关系,创建模型之间的第一关联关系,该第一关联关系可以用于将子对象模型关联到目标对象模型上。
可选的,上述第一关联关系可以用于指示目标对象模型和至少一个子对象模型是父子关系(或者说是包含与被包含关系、整体与部分关系等)。其中,将目标对象模型标识为父模型,将至少一个子对象模型标识为子模型,上述父子关系用于指示子模型从属于父模型,对应到现实中,则表示子对象从属于目标对象。
在本方案中,可以根据目标对象的情况,对各种目标对象进行数字孪生,得到其对应的对象模型,这样,通过对各个对象进行模型创建,为用户提供各对象的信息,实现了对目标对象的数字化管理。同时,通过时间属性记录了对象模型中各个历史数据对应的时间,使得对象模型中保存的信息更加准确、全面。并且,还可以根据现实中对象之间的层级关系,创建对象模型之间的关联关系,这样,通过对象模型间的关联关系,向用户提供了现实中对象之间的关系的信息,提高了用户管理目标对象的效率。
可选的,上述创建的各个对象模型还包括模型标识,该模型标识用于唯一标识对应的对象模型。
示例性的,该模型标识可以是具有固定长度的数字序列。例如,每个对象模型可以由6位数字身份标识号(Identity,ID)唯一标识,目标对象对应的目标对象模型的唯一标识可以记为000010,子对象1对应的子对象模型1的唯一标识可以记为000110,子对象2对应的子对象模型2的唯一标识可以记为000210,子对象3对应的子对象模型3的唯一标识可以记为000310;这样,每个对象模型都可以有其唯一对应的模型标识。
在本方式中,每个模型都具有其全系统唯一模型标识,使得后续访问时能够实现对模型的精准查找,提高了对模型的管理效率。
可选的,上述创建的各个模型还包括成员属性,该成员属性用于描述用户自定义的数据。
具体的,模型的成员属性中可以包含若干成员。所谓成员,指的是一种数据结构,所有对象(实体物或事件)的差异化属性的信息,均可以通过该数据结构进行存储,并保存在该其对应的模型中。
示例性的,参见图4,为本申请实施例提供的一种成员结构的示意图。在图4中,成员包括了不同的成员信息,例如,成员ID、成员名称、成员数据类型以及成员值等。通过这种结构化的数据信息,用户可以为不同的实体物模型增添其对应的成员信息。例如,车间甲对应的目标实体物模型中,可以增加描述车间人数的成员信息,或是描述车间中机器数量的成员信息。依据如图4所示的成员结构,用于描述车间人数的成员信息以及用于描述车间中机器数量的成员信息则可以表示为如表1所示的数据。
表1
在本方式中,用户可以通过成员属性,分别将每个对象(实体物或事件)的差异化信息保存在其对应的模型中,避免了因单独的对象(实体物或事件)所具有的特异化信息而对整体的模型进行修改,提高了本方案的适配性与实用性。
以上介绍了在模型创建时,不论是针对实体物还是事件都可以进行的操作步骤。而面对实体物和事件之间的不同特性,以下将分别介绍如何针对实体物或事件的特性进行模型创建的方法。
首先介绍当目标对象包括第一目标实体物,子对象包括子实体物时,创建对象模型时还可以执行的操作步骤。
可选的,在针对实体物进行模型创建时,创建得到的各类对象模型中还包括空间属性,该空间属性用于描述目标对象模型以及至少一个子对象模型的以下一项或多项信息:坐标系信息、几何形状信息、空间位置信息、空间旋转角度信息、空间范围信息。
其中,坐标系信息用于指示对象模型具体选定的参考坐标系的信息,空间位置信息用于指示对象模型所对应的对象所处的位置信息,几何形状信息用于指示对象模型对应的对象形状的信息,空间范围信息用于指示对象模型对应的对象所在的空间范围信息。其中,需要注意的是,至少一个子对象模型中的空间范围不超过目标对象模型的空间范围。
可选的,基于上述空间属性所包含的信息,对象模型间的第一关联关系还包括在过去时刻,实体物几何形状之间的几何关系,以及空间位置之间的空间关系。
其中,实体物几何形状之间的几何关系用于指示实体物之间存在的相交、相离、接触等关系,同时还可以指示实体物之间的距离等数据。
实体物空间位置之间的空间关系用于指示对象模型对应的实体物在空间上相互之间有联系,例如:包含、相离、接触等,也用于指示对象模型对应的实体物之间有一定的空间距离。
通过上述方式,在对象模型中增加空间属性,使得对象模型所包含的对象信息更加全面完善。同时,对象模型间的关联关系还包括了几何关系以及空间关系,使得各个对象模型之间的联系更加紧密,有助于实现针对对象模型进行的快速查找等管理。
可选的,各个对象模型中空间属性的取值可以通过以下不同方式完成。
方式一、单坐标系
参见图5,为本申请实施例提供的一种为空间属性赋值的方法的流程图。
步骤S501:在目标对象模型中建立第一坐标系,该第一坐标系可以保存在目标对象模型中的空间属性中。
步骤S502:根据第一坐标系确定目标对象模型以及该目标对象关联的至少一个子对象模型的空间位置信息。
步骤S503:根据第一坐标系确定目标对象模型以及至少一个子对象模型的几何形状信息。
步骤S504:服务器根据上述空间位置信息以及几何形状信息,为目标对象模型以及至少一个子对象模型中的空间属性赋值。
在本方式中,服务器仅根据目标对象模型中的第一坐标系,为目标对象以及目标对象模型所关联的子对象模型的空间属性赋值,这样,目标对象与子对象拥有了统一的参考坐标系,其相对位置的关系显示的更为直观且密切,进一步地加强了目标对象模型以及子对象模型之间的关联性,提高了对象模型的管理效率。
方式二、双坐标系
参见图6,为本申请实施例提供的另一种为空间属性赋值的方法的流程图。
步骤S601:服务器在目标对象模型中建立第一坐标系,在第一子对象模型中建立第二坐标系;其中,第一子对象模型为上述至少一个子对象模型中的一个,第二坐标系的原点是根据第一坐标系的原点确定的。
步骤S602:服务器根据第一坐标系确定目标对象模型的空间位置信息,并根据第二坐标系确定与上述目标对象模型关联的至少一个子对象模型的空间位置关系。
这样,所有与目标对象模型关联的子对象模型的空间位置信息均是基于同一个参考坐标系确定的,更有助于对子对象模型的管理。
步骤S603:服务器根据第一坐标系确定目标对象模型的几何形状信息,并根据第二坐标系确定与上述目标对象模型关联的至少一个子对象模型的几何形状信息。
步骤S604:服务器根据上述空间位置信息以及几何形状信息,为目标对象模型以及至少一个子对象模型中的空间属性赋值。
在本方式中,服务器分别在目标对象模型以及子对象模型中建立了第一坐标系以及第二坐标系,并且,第二坐标系的原点是根据第一坐标系的原点建立的,这样,赋值后的各类模型的空间属性即保有内置的关联关系,也具备一定的独立性,提高了精细化管理对象模型的程度。
可选的,上述各类对象模型中还包括位置属性,该位置属性用于描述目标对象在当前时刻之前的至少一个时刻的位置变化,或者,在当前时刻之前的至少一个持续时间段内的位置变化。
示例性的,服务器在为模型中的位置属性进行赋值时,可以在第一目标实体物的空间位置信息发生变化时,将该空间位置信息的变化保存在目标对象模型中。同样,当子实体物的空间位置信息发生变化时,服务器也可以将对应的信息保存在子实体物对应的子对象模型中。
在本方式中,通过位置属性记录了实体物的位置变化情况,完善了对象模型中保有的数据,提高了管理对象模型的程度。
可选的,当上述至少一个子实体物中的第二子实体物的空间位置发生变化,从目标实体物的空间范围内移出时,服务器更新该第二子实体物对应的第二子实体物模型与目标实体物模型的第一关联关系,并更新该第二子实体物模型的空间属性以及时间属性,以确保将该位置变化被记录在第二子实体物模型中。
以车间甲为目标实体物为例,车间甲中的机器1为上述第二子实体物,当机器1出现了从车间甲转移至另一车间的记录时,服务器可以对应的更新车间甲以及机器1对应的目标实体物模型与第二子实体物模型的第一关联关系,并同时更新第二子实体物模型的空间属性以及时间属性,以确保该记录能顺利保存在第二子实体物模型中。
可选的,在孪生第一目标实体物或是至少一个子实体物的历史状态时,还可以通过第一目标实体物或至少一个子实体物对应的目标对象模型或至少一个子对象模型,生成在当前时刻之前至少一个时刻或至少一个持续时间段内,各个对象模型对应的对象记录。
其中,通过目标对象模型生成的对象记录可以被标记为父对象记录,用于描述目标对象在当前时刻之前至少一个时刻或至少一个持续时间段内的属性状态。通过至少一个子对象模型生成的对象记录可以被称为子对象记录,用于描述至少一个子对象在当前时刻之前至少一个时刻或至少一个持续时间段内的属性状态。
示例性的,通过完成建立的目标对象模型中包含的历史状态,生成一条用于描述该历史状态的父对象记录,该记录中包含了目标对象模型对应历史状态中的各个属性的值。例如,根据车间甲成立这一历史状态,生成一条父对象记录,该父对象记录中则包含了车间甲投入使用的时间、车间甲所处的空间位置、车间甲投入使用时包含的车间人员等等。
在本方式中,通过模型生成应的对象记录,使得用户能够获得关于对象统一且规范的历史状态信息,提高了用户的使用体验,并且降低了获取信息的复杂度。
可选的,对于生成的父对象记录以及至少一个子对象记录,还可以执行以下处理方式:建立父对象记录与至少一个子对象记录的第二关联关系,该第二关联关系用于将至少一个子对象记录关联至父对象记录,或者,该第二关联关系还用于指示父对象记录对应的实体物模型与至少一个子对象记录对应至少一个子实体物模型具有第一关联关系。
其中,至少一个子对象记录中的每个子对象记录都具有唯一的父对象记录,且记录中均包括时间范围这一属性,用于指示各个记录所对应的属性状态所持续的时间范围。并且,至少一个子对象记录中的每个子对象记录的时间范围都在父对象记录的时间范围之内。
在本方式中,将生成的父对象记录与子对象记录进行联系,能够贯彻实体物之间的关联关系,加强对象之间、信息之间的关联关系,提高了对象信息管理的效率。
可选的,当目标对象模型的空间属性中包含空间范围信息时,上述目标对象模型对应的父对象记录以及至少一个子对象模型对应的子对象记录用于描述该目标对象以及至少一个子对象在当前时刻之前至少一个时刻或当前时刻之前至少一个持续时间段内的空间范围的变更信息。
需要说明的是,在当前时刻之前的至少一个时刻或当前时刻之前的至少一个持续时间段内,子对象记录中的空间范围被包含在所述父对象记录的空间范围内。
在本方式中,对象记录中包含了对应的实体物的空间范围变化情况,能够有效地帮助用户获得对应信息。
可选的,当目标对象模型的空间属性中包含空间位置信息时,上述目标对象模型对应的父对象记录以及至少一个子对象模型对应的子对象记录还用于描述该目标对象以及至少一个子对象在当前时刻之前至少一个时刻或当前时刻之前至少一个持续时间段内的空间位置移动的变更信息。
需要说明的是,在当前时刻之前的至少一个时刻或当前时刻之前的至少一个持续时间段内,至少一个子对象的空间位置被包含在所述父对象记录的空间范围内。
在本方式中,对象记录中包含了对应的对象的空间位置变化情况,能够有效地帮助用户获得对应信息。
可选的,当目标对象模型的空间属性中包含几何形状信息时,上述目标对象模型对应的父对象记录以及至少一 个子实体物模型对应的子对象记录用于描述该目标对象以及至少一个子对象在当前时刻之前至少一个时刻或当前时刻之前至少一个持续时间段内的几何形状的变更信息。
需要说明的是,在当前时刻之前的至少一个时刻或当前时刻之前的至少一个持续时间段内,子对象记录中的几何形状被包含在所述父对象记录的几何形状内。
在本方式中,对象记录中包含了对应的实体物的几何形状变化情况,能够有效地帮助用户获得对应信息。
以上介绍了目标对象包括第一目标实体物时,可以执行的方法步骤。以下将对目标对象包括目标事件,子对象包括子事件时,创建模型时可以执行的步骤进行介绍。
应理解,在现实世界中,事件的发生通常会与实体物有关,因此,在针对事件创建模型时,还可以对与该事件相关的实体物一并进行模型创建。为了与上述目标对象可能包括的第一目标实体物进行说明上的区分,以下介绍的与事件相关的实体物将被记为第二目标实体物。需要说明的是,该第二目标实体物指的是与目标对象包括的目标事件相关的实体物,而上述第一目标实体物可以是任意实体物。换言之,在某种程度上,第一目标实体物中可以包括第二目标实体物。
参见图7,为本申请实施例提供的一种孪生第二目标实体物的历史状态的方法的流程图,该方法具体步骤如下:
步骤S701:针对第二目标实体物建立第二目标实体物模型,该第二目标实体物模型用于描述第二目标实体物的历史状态,且该模型中包括时间属性。
步骤S702:将第二目标实体物模型中的时间属性的取值确定为第二历史时间,该第二历史时间用于表示第二目标实体物模型中数据对应的时间。
其中,第二目标实体物模型中的时间属性的取值用于描述的是第二目标实体物模型中存在的数据对应的时间,例如,假设第二目标实体物为笔记本电脑时,那么在该第二目标实体物对应的第二目标实体物模型中存在某一历史数据,记录了该实体物投入使用的信息,那么,该数据对应的时间属性的取值即为该实体物投入使用的时间,而非该历史数据被记录的时间。
步骤S703:建立第二目标实体物模型与目标事件模型的第三关联关系,该第三关联关系用于将第二目标实体物模型关联至目标事件模型。
应理解,上述第二目标实体物模型创建的具体步骤与目标对象模型创建的具体步骤类似,此处不再赘述。
具体的,在创建第二目标实体物模型后,基于第二目标实体物与目标事件在现实中的关联关系,建立第二目标实体物模型与目标对象模型之间的第三关联关系。例如,假设第二目标实体物为工厂A,而目标对象为发生在工厂A中的请假事件,那么,此时,第二目标实体物与目标对象具有空间关系,该空间关系指示了目标对象发生在目标实体物的空间范围内。因此,在创建完成第二目标实体物模型以及目标事件模型后,依据上述空间管理,建立第二目标实体物模型与目标对象模型之间的第三关联关系,将第二目标实体物模型关联至目标对象模型。
在本方式中,创建了与目标对象模型相关联的第二目标实体物模型,完善了对事件历史状态进行孪生的方案,加强了模型中保存信息的全面性,提高了事件信息的管理效率。
可选的,在上述创建针对各类事件创建的对象模型中,还包括空间属性,该空间属性用于描述目标事件以及至少一个子事件发生时的位置信息。
示例性的,以上述目标事件为请假事件,至少一个子事件为请假事件拆分出的子事件1、2、3为例,请假事件发生时的位置可能是工厂A,而子事件发生时的位置则可能分别是车间甲、车间甲以及行政楼。这些位置信息被对应保存在创建出的对象模型中,以完善模型中的数据对于发生的事件的描述。
可选的,上述模型中的空间属性可以包括空间范围和/或空间位置。其中,子对象模型中记录的空间范围被包含在子对象模型对应的父模型的空间范围内;或者说,子对象模型中记录的空间位置被包含在该子对象模型对应的父模型的空间位置的范围内。
可选的,在孪生目标对象模型、至少一个子对象模型以及第二目标实体物模型的历史状态时,还可以根据目标事件在历史不同时间的属性参数,基于该事件对应的目标对象模型,生成对应的目标事件对象记录;其次,根据上述至少一个子对象模型在历史不同时间的属性参数,基于该时间对应的至少一个子对象模型,生成对应的子事件对象记录。其中属性参数包括属性名称、数据类型、属性值中的至少一种。
示例性的,通过完成建立的目标对象模型中包含的历史状态,生成一条用于描述该历史状态的目标事件对象记录,该记录中包含了目标对象模型对应的历史状态中的各个属性的值。示例性的,该目标事件记录中可以包含请假 事件发生的时间、空间位置以及空间范围。
在本方式中,通过模型生成应的对象记录,使得用户能够获得关于对象统一且规范的历史状态信息,提高了用户的使用体验,并且降低了获取信息的复杂度。
可选的,对于生成的目标事件对象记录以及至少一个子事件对象记录,还可以执行以下处理方式:
建立目标事件对象记录与至少一个子事件对象记录的第四关联关系,该第四关联关系用于将至少一个子事件对象记录关联至目标事件对象记录。
其中,至少一个子事件对象记录中的每个子事件对象记录都有且只有一个目标事件对象记录,所有对象记录中均包含时间范围这一属性,用于指示各个记录所对应的属性状态所持续的时间范围。并且,子事件对象记录中的时间范围在目标事件对象记录的时间范围之内。
在本方式中,将生成的目标事件对象记录与子事件对象记录进行联系,能够贯彻对象之间的关联关系,加强了对象之间、信息之间的关联关系,提高了对象信息管理的效率。
以上介绍了通过建立对象模型实现对象(即实体物或事件)历史状态的孪生的方案。基于同一发明构思,以下介绍建立后的模型的几种可能的应用。
应用1、订阅对象的历史状态
参见图8,为本申请实施例提供的一种订阅目标对象历史状态的方法的流程图。该方法由与终端设备通信相连的计算机、服务器等设备共同执行,为便于说明,下面以服务器与终端设备为例,描述本方法的具体实施步骤。
步骤S801:服务器接收来自终端设备的第一请求,该第一请求用于请求订阅目标对象的历史状态。
其中,该第一请求中可以携带用于确定目标对象模型的信息,而该信息具体可以是:目标对象模型的模型标识;或者,目标对象模型中的一个或多个属性的值;或者,目标对象模型的模型标识以及目标对象模型中的一个或多个属性的值。
例如,当终端设备需要订阅目标对象模型时,可以向服务器发送第一请求,该第一请求中携带了目标对象模型的模型标识,服务器接收到该第一请求后,即可根据该模型标识完成对目标对象模型的订阅操作。
这样,服务器可以通过第一请求中携带的信息,从若干对象模型中确定出目标对象模型。而这若干对象模型则存储在服务器对应的数据库中(在创建完成若干对象模型后,这些对象模型即可存储在服务器对应的数据库中,如此,确保了后续信息查询的可靠性)。
步骤S802:服务器响应于第一请求,对目标对象模型执行订阅操作。
示例性的,该订阅操作可以是将被订阅的目标对象模型的标识信息保存在对应的订阅数据表中,该订阅数据表中记录有所有被订阅的对象模型的标识信息。
仍以目标对象模型为例进行说明,服务器在接收到请求订阅目标对象模型的第一请求后,响应于该第一请求,将目标对象模型的模型标识保存至订阅数据表中,用以实现对目标对象模型的订阅。
步骤S803:服务器从若干对象模型中确定出至少一个子对象模型,所述至少一个子对象模型与目标对象模型具有第一关联关系;对至少一个子对象模型执行订阅操作。
示例性的,服务器在确定目标对象模型后,从目标对象模型中获取目标对象模型与至少一个子对象模型的第一关联关系的相关信息,并根据该第一关联关系的信息从若干对象模型中确定出上述至少一个子对象模型,即,子对象模型1、子对象模型2、子对象模型3,并随即订阅这三个对象模型。类似的,当服务器接收到的第一请求是用于订阅子对象模型1时,根据子对象模型1中与第一关联关系相关的信息,服务器可以根据该第一关联关系确定目标对象模型,并随之订阅目标对象模型。换言之,服务器既可以根据关联关系,从父模型中确定并订阅子模型,也可以根据关联关系,从子模型中确定并订阅父模型。
步骤S804:当目标对象模型和/或至少一个子对象模型发生变化时,将变化情况发送至终端设备。
在完成对目标对象模型与至少一个子对象模型的订阅之后,服务器会检测这些模型的数据情况,一旦发生目标对象模型和/或至少一个子对象模型的数据发生变换,或是发生了子对象模型变化时,服务器即刻向终端设备发送上述变化情况。其中,子对象模型变化用于指示与目标对象模型具有第一关联关系的子对象模型的数量发生变化,以目标对象模型是车间甲为例,当车间甲中的部分机器被淘汰时,车间甲中存在的机器数量会发生变化,此时,与目标实体物模型具有第一关联关系的子对象模型的数量也会发生变化,此时,即表示发生了子对象模型变化。
在本方案中,基于模型之间存在第一关联关系,在订阅目标对象模型后,可以根据目标对象模型中的关联关系, 对被关联到的至少一个子对象模型执行同样的订阅操作。这样在用户只需发出订阅目标对象模型的指示,就可以同时订阅与目标对象模型相关联的模型,并及时获得这些模型的变化信息。能够以简单的操作获得更全面的信息,提高了订阅操作的智能化程度。
需要说明的是,以上仅以模型之间的第一关联关系为例进行了说明,当目标对象包括目标事件时,其对应创建的目标对象模型还可能会包含有与第二目标实体物模型之间的第三关联关系。因此,在实际应用中,还可以根据目标对象模型与第二目标实体物模型之间的第三关联关系,进行上述订阅过程;或者同时根据目标对象模型中包括的第一关联关系以及第三关联关系进行上述订阅操作,即:在请求订阅目标对象模型后,同时订阅至少一个子对象模型以及第二目标实体物模型。
可选的,服务器向终端设备发送变化情况时,可以选择以下方式进行发送:
当目标对象模型和/或至少一个子对象模型发生变化时,生成与订阅项相匹配的订阅信息,其中,订阅项是第一请求中携带的;将订阅信息发送至终端设备。
其中,第一请求中携带的订阅项可以是对象模型中包含的各类属性的名称,例如空间属性或是位置属性等;还可以是对象模型中用户需要重点关注的部分信息,例如,可以是成员属性中成员的名称。
这样,当对象模型中的数据发生变化时,服务器可以根据第一请求中包含的订阅项,对应地生成订阅信息,例如,第一请求中携带的订阅项仅包括空间属性,当目标对象模型和/或至少一个子对象模型的空间属性发生变化时,服务器生成的订阅信息可以是只用于指示目标对象模型和/或至少一个子对象模型的空间属性的变化的订阅信息。
在本方式中,服务器依据第一请求中携带的订阅项,为终端设备发送对应的订阅信息,既能够满足用户的订阅需求,也避免了用于对其它模型信息的跟踪,实现了对象信息的精细化管理。
应用2、查询目标对象的历史状态
参见图9,为本申请实施例提供的一种查询目标对象历史状态的方法的流程图。该方法具体步骤如下:
S901:服务器接收来自终端设备的第二请求,该第二请求用于查询目标对象模型。
与应用1类似,该第二请求中可以携带用于确定目标对象模型的信息,而该信息具体可以是:目标对象模型的模型标识;或者,目标对象模型中的一个或多个属性的值;或者,目标对象模型的模型标识以及目标对象模型中的一个或多个属性的值。
步骤S902:服务器响应于该第二请求,从若干对象模型中确定出目标对象模型。
步骤S903:服务器根据目标对象模型中有关第一关联关系的信息,从若干对象模型中确定出至少一个子对象模型,该至少一个子对象模型对应的实体物与目标对象模型对应的实体物具有第一关联关系。
步骤S904:服务器向终端设备输出目标对象模型与至少一个子对象模型的信息。
这样,服务器即可根据目标对象模型与至少一个子对象模型之间的第一关联关系,从父模型确定出子模型,并同时将其输送至终端设备,以完成对第二请求的响应。
在本方式中,用户只需要输入一个对象模型的查询信息,即可获取若干与该对象模型关联的对象模型的信息,简化了用户的查询操作,提高了用户的使用体验。
可选的,第二请求中还可以携带查询项,用以指示服务器根据对应的查询项进行反馈。
示例性的,查询项可以是对象模型中的空间属性和/或成员属性,而服务器在接收到包含查询项的第二请求时,从确定出的目标对象模型中确定出空间属性和/或成员属性的信息,并生成对应的查询信息发送至终端设备。
在本方式中,通过查询项的限制,可以由针对性的发送对象模型中的信息,提高了对对象模型管理的精细化程度。
应用3、删除目标对象的历史状态
参见图10,为本申请实施例提供的一种删除目标对象历史状态的方法的流程图。该方法具体步骤如下:
S1001:服务器接收来自终端设备的第三请求,该第三请求用于删除目标对象模型。
S1002:响应于第三请求,服务器从若干对象模型中确定出目标对象模型,并根据目标对象模型中的有关第一关联关系的信息,确定出与目标对象模型具有第一关联关系的至少一个子对象模型。
S1003:删除目标对象模型与至少一个子对象模型。
在本方式中,通过目标对象模型与至少一个子对象模型的第一关联关系,在接收到删除目标对象模型的指令后,同时删除与目标对象模型具有第一关联关系的至少一个子对象模型,简化了用户操作,提高了用于的使用体验。
以上介绍了基于目标对象模型与至少一个子对象模型之间的第一关联关系进行的订阅、查询、删除操作,但是实际使用中,不仅仅可以只根据第一关联关系进行上述操作,还可以根据各个对象模型之间的空间关系进行对象模型的订阅、查询、删除操作。
以空间属性为例,如图3所示,机器1、2、3所占据的空间范围包含于车间甲所占据的空间范围内,此时,车间甲与机器1、2、3存在包含与被包含的空间关系。这样,在执行订阅、查询、删除操作时,服务器可以根据车间甲对应的目标实体物模型具有的空间关系,确定出机器1、2、3对应的子实体物模型1、2、3,并对其执行对应地操作。
