本实施例提供了一种基于数字孪生映射的主从联动控制方法,图1是根据本申请实施例的基于数字孪生映射的主从联动控制方法的流程图一,如图1所示,该方法包括如下步骤:
步骤S101:加载预设数字孪生系统,预设数字孪生系统包括:数字孪生体和验证模型,数字孪生体为从设备在数字空间中的动态复制体,验证模型是在数字空间中用于进行碰撞验证的数字模型;
需要说明的是,数字孪生技术是充分利用物理模型、传感器更新、运行历史等数据,集成多学科、多物理量、多尺度、多概率的仿真过程,在虚拟空间中完成映射,从而反映相对应的实体装备的全生命周期过程;它可以完全绕过现实实物也就是从设备,直接通过操控数字孪生体进行模拟、仿真和预测。
步骤S102:获取主设备运动时的运动参数,将运动参数输入到数字孪生体中,获取数字孪生体执行运动参数得到的运动结果;
需要说明的是,从设备为位于屏蔽室中的从机械手,主设备为位于屏蔽室外的主机械手,主机械手可以是操作人员直接人为施加作用力,来使其运动,在主机械手运动时获取主机械手的运动参数;将主设备的运动参数输入到数字孪生体中,能够使得数字孪生体实时映射当前从机械手各个关节的空间状态,且还能够对数字孪生体进行缩放、透视以及360转角观察,方便对从设备的精细化操作。
步骤S103:通过验证模型对运动结果进行碰撞验证;
其中,验证模型中可以是预先设置有验证数据,能够将数字孪生体执行运动参数得到的运动结果与验证数据进行匹配,进而来判断碰撞验证是否通过。
步骤S104:若碰撞验证通过,则根据运动参数控制从设备运动,否则进行告警。
通过步骤S101至步骤S104,基于数字孪生技术,在虚拟空间中完成从设备的映射,也就是数字孪生体为从设备在数字空间中的动态复制体,一方面,将主设备的运动参数输入到数字孪生体中,能够使得数字孪生体实时映射当前从机械手各个关节的空间状态,方便对从设备的精细化操作,另一方面,将主设备的运动参数在输入至屏蔽室中从设备之前,先将主设备的运动参数输入到数字孪生体中,能够对数字孪生体执行运动参数得到的运动结果进行碰撞验证,在碰撞验证通过后则根据运动参数控制从设备运动,进而即使主设备与从设备结构上存在差异时,由于有防碰撞验证环节的存在,提高了从设备运行的安全性,解决了相关技术中对屏蔽室内从设备远程操作时存在不易观察的问题,方便操作人员对屏蔽室内的从设备进行观察,掌握屏蔽室内从设备的运行状况,并提高了从设备运行的安全性。
在其中一些实施例中,图2是根据本申请实施例的通过验证模型对运动结果进行碰撞验证的方法流程图,如图2所示,该方法包括如下步骤:
步骤S201:控制验证模型根据运动结果进行运动,并判断验证模型运动过程中预设的碰撞区是否被接触;
步骤S202:若碰撞区均未被接触,则碰撞验证通过,否则碰撞验证不通过;
需要说明的是,验证模型可以是设有碰撞区的数字孪生体的复制体,也可以理解为验证模型是从设备的仿真模型,进而验证模型可以是由各个虚拟关节组成的,碰撞区可以是各个关节的外轮廓,也可以是预先设置的验证模型的周边区域,其中,周边区域可以是根据屏蔽室内从设备所在位置处的环境信息进行设置的。当验证模型根据运动结果进行运动时,若存在碰撞区均未被接触到,则碰撞验证通过,一旦存在碰撞区被接触到,则进行告警,也即是则碰撞验证不通过。
在其中一些实施例中,运动参数包括各关节角度,图3是根据本申请实施例的获取主设备运动时的运动参数的方法流程图,如图3所示,该方法包括如下步骤:
步骤S301:获取主设备运动时的各主电机角度;
步骤S302:根据各主电机角度,确定主设备运动时的各关节角度。
其中,主设备也就是主机械手,可以是操作人员人为施加作用力来驱使主设备各关节运动,考虑到主设备的各关节运动是依靠人为施加的作用力,进而主设备各关节运动的角度与人为施加作用力的大小有关;主设备各关节运动,则主设备中的各主电机进行转动,进而可通过获取主电机转动的角度,来间接确定主设备运动时的各关节角度;
其中,电机角度=电机减速比*关节角度,进而可在已知电机减速比和电机角度的情况 下,确定关节角度;考虑到主设备中电机所控制的机械手部件位置不同,存在电机减速比的不同,进而可根据对应机械手部件位置的电机减速比和电机角度,确定该机械手部件位置处的关节角度。
通过上述步骤S301至步骤S302,根据主设备运动时的各主电机角度,来反推主设备运动时的各关节角度,使得所确定的主设备各关节角度,更加精确。
在其中一些实施例中,图4是根据本申请实施例的根据运动参数控制从设备运动的方法流程图一,如图4所示,该方法包括如下步骤:
步骤S401:若碰撞验证通过,则将各关节角度转换成与从设备相对应的各从电机角度;
步骤S402:根据各从电机角度控制从设备运动;
需要说明的是,从设备的运动是由设于屏蔽室外部的与从设备相对应的各从电机通过控制齿轮耦合,来实现从设备各关节的运动,进而在已知各关节角度的情况下,来确定与从设备相对应的各从电机角度,便于从设备中的各个从电机根据对应的从电机角度精确控制从设备的运动,以完成特定环境下屏蔽室内的操作任务。
在其中一些实施例中,图5是根据本申请实施例的根据运动参数控制从设备运动的方法流程图二,如图5所示,若碰撞验证通过,则将各关节角度转换成与从设备相对应的各从电机角度包括如下步骤:
步骤S501:获取从设备中各从电机的减速比;
步骤S502:根据各减速比与各关节角度的乘积,确定各从电机角度。
需要说明的是,从设备中各从电机所控制的机械手部件位置不同,存在从电机减速比的不同,利用电机角度=电机减速比*关节角度,可根据对应从机械手部件位置的从电机减速比和关节角度,确定该从机械手部件位置处的关节角度。
在其中一些实施例中,图6是根据本申请实施例的基于数字孪生映射的主从联动控制方法的流程图二,如图6所示,该方法还包括如下步骤:
步骤S601:获取从设备运动时的各关节扭矩增量;
其中,从设备运动时的各关节扭矩增量,是指从设备末端负载所引起的关节扭矩增量,各关节扭矩增量可通过从设备各关节的实际关节扭矩和初始关节扭矩相减得到;
步骤S602:根据各关节扭矩增量和预设的增量,判断从设备的负载是否超过预设负载;
例如,将各关节扭矩增量与对应的预设增量进行比较,得到偏差,如果偏差较小,则说明是主从联动的系统误差,可触发主设备对从设备做运动补偿;如果偏差较大,则说明不仅仅是系统引起的误差,存在从设备的负载(从设备的实际负载)远超预设负载,则需要调整负载参数;在调整负载参数后,可得到新的预设增量,直到各关节扭矩增量和新的 预设增量的偏差在合理范围内,则说明调整的负载参数是合理的。
通过步骤S601至步骤S602,根据从设备运动时的各关节扭矩增量与预设的增量,来判断从设备的负载是否超过预设负载,进而便于调控从设备的负载参数,降低从设备超预设负载工作的时间,提高从设备的使用寿命。
在其中一些实施例中,数字孪生体包括第一数字孪生体和第二数字孪生体,第一数字孪生体和第二数字孪生体均为从设备在数字空间中的动态复制体;获取主设备运动时的运动参数,将运动参数输入到数字孪生体中,获取数字孪生体执行运动参数得到的运动结果包括:获取主设备运动时的运动参数,将运动参数输入到第一数字孪生体中,获取第一数字孪生体执行运动参数得到的运动结果。
图7是根据本申请实施例的基于数字孪生映射的主从联动控制方法的流程图三,如图7所示,通过验证模型对运动结果进行碰撞验证之后,该方法还包括:
步骤S701:若碰撞验证通过,则根据运动参数控制第二数字孪生体运动;
其中,若碰撞验证通过则控制从设备根据运动参数进行运动的同时,也控制从设备的复制体——第二数字孪生体根据运动参数进行运动,这样的情形下,位于屏蔽室内外的第二数字孪生体与位于屏蔽室内的从设备实时映射,也就是第二数字孪生体的运动情况始终与屏蔽室内从设备的运动情况保持一致;
步骤S702:获取第二数字孪生体在单位时间内的运动信息;
例如,可以是以天为单位记录第二数字孪生体在几个月的运动信息,如,第二数字孪生体中各从电机角度、各从电机运动每天运动的时间等;
步骤S703:根据运动信息预测从设备的使用寿命;
例如,可根据所记录的大量的第二数字孪生体的运动信息,基于大量信息的积累,并结合实际经验,来间接预测屏蔽室内从设备中各重要元器件的寿命范围,当其接近最大寿命范围时,可进行相应元器件或者从设备的更换提醒。
通过上述步骤S701至步骤S703,基于位于屏蔽室内外的第二数字孪生体与位于屏蔽室内的从设备实时映射,进而通过位于屏蔽室内外的第二数字孪生体的运动信息来间接预测屏蔽室内从设备的使用寿命,便于操作人员进行及时检修和更换。
需要说明的是,在上述流程中或者附图的流程图中示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行,并且,虽然在流程图中示出了逻辑顺序,但是在某些情况下,可以以不同于此处的顺序执行所示出或描述的步骤。
在一些实施例中,图8是根据本申请实施例的基于数字孪生映射的主从联动控制系统的结构框图,如图8所示,基于数字孪生映射的主从联动控制系统包括主设备81、主控制 器82、工控机83、从控制器84和从设备85;

其中,工控机83还可对数字孪生体进行展示,工控机83上展示的数字孪生体可接受操作人员输出的控制指令进行缩放、透视以及360转角观察,方便操作人员间接实现对从设备85的精细化操作。
从控制器84,一端与工控机83连接获取运动参数,另一端与从设备85连接用于根据运动参数控制从设备85运动。
上述的基于数字孪生映射的主从联动控制系统,基于数字孪生技术,在虚拟空间中完成从设备的映射,也就是数字孪生体为从设备在数字空间中的动态复制体,一方面,将主设备的运动参数输入到数字孪生体中,能够使得数字孪生体实时映射当前从机械手各个关节的空间状态,方便对从设备的精细化操作,另一方面,将主设备的运动参数在输入至屏蔽室中从设备实体之前,先将主设备的运动参数输入到数字孪生体中,能够对数字孪生体执行运动参数得到的运动结果进行碰撞验证,在碰撞验证通过后则根据运动参数控制从设备运动,进而即使主设备与从设备结构上存在差异时,由于有防碰撞验证环节的存在,提高了从设备运行的安全性,解决了相关技术中对屏蔽室内从设备远程操作时存在不易观察的问题,方便操作人员对屏蔽室内的从设备进行观察,掌握屏蔽室内从设备的运行状况,并提高了从设备运行的安全性。
