具体实施方式
为使本发明的目的、技术方案和优点更加清楚,下面将结合本发明中的附图,对本发明中的技术方案进行清楚、完整地描述,显然,所描述的实施例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作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
下面结合图1-图6描述本发明的一种吊装路径规划模型构建方法、吊装路径规划方法及起重机。
图1是本发明提供的吊装路径规划模型构建方法的流程示意图。
如图1所示,本发明实施例提供的一种吊装路径规划模型构建方法,执行主体可以是远程控制系统,具体包括以下步骤:
101、建立起重机模型。
吊装是指起重机对设备的安装、就位的统称,在检修或维修过程中利用各种起重机将设备、工件、器具、材料等吊起,使其发生位置变化。
具体的,首先要建立起重机模型,也就是模拟起重机,将起重机以数字形式表达出来,可以理解为将起重机放置于坐标系内,起重机的各个组件结构都对应着不同的坐标。在数据库内仿真起重机,从而建立起重机模型。针对不同规格的起重机,由于其自身参数不同,所以建立的起重机模型也有所不同。
102、基于当前作业场景和起重机模型,构建吊装系统位形空间模型,吊装系统位形空间模型包括起重机的上车数据和下车数据。
确定起重机的当前作业场景,当前作业场景指的是起重机要进行作业的区域,例如,起重机在建筑工地,便可以将建筑工地作为当前作业场景。再将起重机模型放置于当前作业场景之中,构建吊装系统位形空间模型,其中,吊装系统位形空间模型可以是多维系统模型。吊装系统位形空间模型的表达式可以如(1)所示:
T=(C(p,d),U(α,β,L))   (1)
其中,C表示起重机的下车数据,U表示起重机的上车数据,p表示起重机的笛卡尔坐标,d表示起重机的方向向量,α表示主臂变幅角度,β表示上车回转角度,L表示吊钩升降长度,此处忽略的臂架长度数据,臂架的长度预先可知,如桁架臂架,基于已知的各段臂节,通过简单的加减可计算出臂架长度,伸缩式臂架可通过安装在臂架上的长度传感器预先测出。
当起重机状态确定时,也就是起重机位置保持不变没有移动时,可以实现起重机位形坐标(α,β,L)到笛卡尔坐标(x,y,z)的 相互转换。
整体来说,即吊装系统位形空间模型中展示着起重机的多种状态,包括下车数据中的行走参数、转向参数,上车数据中的主臂变幅角度、上车回转角度和吊钩升降长度等,使得吊装系统位形空间模型能够更加全面的反映出起重机的状态信息。
103、针对吊装系统位形空间模型和上车数据,生成起重机的上车栅格图数据;针对吊装系统位形空间模型和下车数据,生成起重机的下车栅格图数据。
具体的,在构建得到吊装系统位形空间模型之后,需要分别针对起重机的上车数据和下车数据进行单独的处理。根据起重机的工作特点,将其动作分成两个组合,一组为包含主臂变幅角度、上车回转角度和吊钩升降长度的上车动作,另一组为包含行走参数和转向参数的下车动作,由此将吊装系统位形空间模型的数据分为两次计算,减小了单次计算难度,也降低了耦合度。
当起重机不移动时,也就是在下车数据中的行走参数和转向参数确定的前提下,每一个U坐标代表起重机的一个位形状态,因此,便需要建立上车数据的所有上车栅格图数据,上车栅格图数据指的是主臂变幅角度、上车回转角度和吊钩升降长度所构成的栅格图。即主臂变幅角度、上车回转角度和吊钩升降长度这三个自由度,每种都有若干种大小不一的数据,然后分别将其进行排列组合,便可以构成整个的上车栅格图数据。
当起重机发生移动时,即下车数据中的行走参数和/或转向参数发生变化时,便需要计算出起重机的下车栅格图数据。其中,生成下车栅格图数据的方式与上车栅格图数据的生成方式相同,下车栅格图数据表示的为两个自由度方向的数据。
104、利用A星算法,结合上车栅格图数据和下车栅格图数据,构建吊装路径规划模型。
具体的,在得到上车栅格图数据和下车栅格图数据之后,便可以构建吊装路径规划模型。上车栅格图数据包括有若干个节点,下车栅格图数据中也包括有若干个节点,而不同的节点之后便会构成若干条线路,即若干条吊装路径。
利用A星算法,在上车栅格图数据和下车栅格图数据中进行寻优,将A星算法与上车栅格图数据和下车栅格图数据进行结合,便成功地构建出吊装路径规划模型。吊装路径规划模型的工作原理便是,在当前作业场景内得到上车栅格图数据和下车栅格图数据,然后利用A星算法,在上车栅格图数据和下车栅格图数据中进行遍历搜寻,从而得到目标路径。而采用A星算法规划路径具有全局最优性和连续性好的优点,能够有效精简位形数据量,降低计算复杂度。
本实施例提供的一种吊装路径规划模型构建方法,包括:建立起重机模型;基于当前作业场景和起重机模型,构建吊装系统位形空间模型,吊装系统位形空间模型包括起重机的上车数据和下车数据;针对吊装系统位形空间模型和上车数据,生成起重机的上车栅格图数据;针对吊装系统位形空间模型和下车数据,生成起重机的下车栅格图数据;利用A星算法,结合上车栅格图数据和下车栅格图数据,构建吊装路径规划模型,由于构建的吊装路径规划模型是基于上车栅格图数据和下车栅格图数据,使得通过将整个的路径划分为上车和下车两组,有效地降低了路径搜索时的数据量,提高了路径规划效率。
进一步的,在上述实施例的基础上,本实施例中的上车数据包括:主臂变幅角度、上车回转角度和吊钩升降长度;对应的,针对吊装系统位形空间模型和上车数据,生成起重机的上车栅格图数据,包括:确定吊钩升降长度;划分吊钩升降长度为预设数量的升降区间;针对每个升降区间的端点,基于主臂变幅角度和上车回转角度在吊装系统位形空间模型内进行遍历搜索,计算上车碰撞信息,生成起重机的上车栅格图数据。
具体的,起重机的上车数据中主臂变幅角度、上车回转角度和吊钩升降长度三个动作,其三个动作之间的关系为:在起重机工作时,吊钩升降长度动作往往是在吊装过程的起始和结尾进行的动作,而主臂变幅角度、上车回转角度则是中间过程的动作。因此,为了进一步提高路径搜索的速度,可以选择将吊钩升降长度L作为控制参数进行上车栅格图数据的获取。
划分吊钩升降长度为预设数量的升降区间,然后获取每个升降区间的端点,即L={L0,L1,L2,L3,L4……Lm},对应的区间则是【L0,L1】、【L1,L2】、【L2,L3】……【Lm-1,Lm】。然后按主臂变幅角度α和上车回转角度β进行遍历搜索,(α,β)={(α0,β0),(α0,β1),(α0,β2)……(α1,β0),(α1,β1),(α1,β2)……(αn,βq)},计算上车碰撞信息,针对每一个L端点数据均生成一组对应的栅格图数据。图2是本发明提供的栅格图的结构示意图。如图2所示,为栅格图示意图,其中,径向方向为主臂变幅角度相关,旋转角度为上车回转角度,因此每组栅格图数据的每个栅格中包含碰撞信息、边缘信息、载荷信息等,而每一个设定的吊钩升降长度L对应一组这样的数据,一共有m组对应的栅格图数据。所有的m组栅格图数据构成了整个的起重机上车栅格图数据。通过对m组栅格图数据进行路径规划,可得到n条有效路径(指从起点到终点具有n种路径),比较n条有效路径,选出最优的路径作为当前的结果路径。
进一步的,在上述实施例的基础上,本实施例中的下车数据包括行走参数和转向参数;对应的,针对吊装系统位形空间模型和下车数据,生成起重机的下车栅格图数据,包括:基于行走参数和转向参数,在吊装系统位形空间模型内进行扫描遍历,得到下车碰撞信息;根据下车碰撞信息,生成起重机的下车栅格图数据。
具体的,上述实施例对生成起重机的上车栅格图数据方式进行了 具体说明。因此,在起重机移动时,需要先取得上车数据的碰撞结果,然后再去计算下车数据的碰撞结果,结合上车碰撞结果和下车碰撞结果,得到最终的碰撞结果。其实际意义表示起重机在下车的行走、转向和上车的变幅、回转、吊钩升降时都确保整个吊装系统不发生碰撞。
其中,生成下车栅格图数据的过程则是,首先基于行走参数和转向参数,在吊装系统位形空间模型内进行扫描遍历,得到下车碰撞信息,然后再根据下车碰撞数据,生成下车栅格图数据。下车栅格图数据指的便是起重机行走参数与转向参数的一一对应关系,下车栅格图数据则能够反映出所有的行走参数条件下对应的转向参数,同理也能够反映出所有的转向参数条件下对应的行走参数。
进一步的在上述实施例的基础上,本实施例中的利用A星算法,结合上车栅格图数据和下车栅格图数据,构建吊装路径规划模型,可以包括:利用A星算法,分别对上车栅格图数据和下车栅格图数据进行路径规划,得到上车路径规划模型和下车路径规划模型;结合上车路径规划模型和下车路径规划模型,构建吊装路径规划模型。
具体的,A星算法又称为A*搜寻算法。A星算法的特点是在检查最短路径中每个可能的节点时引入了全局信息,对当前节点距终点的距离做出估计,并作为评价该节点处于最短路线上的可能性的量度。因此,在本实施例中采用A星算法可以更好地完成路径的规划。
为了在路径规划的过程中,尽量的减少数据处理量,增加数据处理的速度。分别对上车栅格图数据和下车栅格图数据进行路径规划,通过分组处理能够降低单次计算难度,降低耦合度。通过将吊装路径规划模型分割为上车路径规划模型和下车路径规划模型,也能够使得在下车没有移动时,更加快速的完成上车路径规划,并且通过A星算法进行路径规划,能够做到全局性最优。
进一步的,在上述实施例的基础上,本实施例中的建立起重机模型,可以包括:获取起重机的结构数据,结构数据包括尺寸信息、运 动参数和载荷参数;基于尺寸信息、运动参数和载荷参数,建立起重机模型。
具体的,获取起重机的结构数据的方式可以是直接读取起重机的产品说明书,也可以是人为输入关键数据,也可以是通过各种传感器测量不同的数据,只要能够准确地获取到起重机的结构数据即可。在准确的获取到起重机的尺寸信息、运动参数和载荷参数之后,将其转化为空间模型,也就是通过线条的方式模拟起重机结构进行仿真。通过准确地获取尺寸信息、运动参数和载荷参数,也能够保证模拟起重机的准确度,从而提高吊装路径规划模型的精准度。
基于同一总的发明构思,本发明还保护一种吊装路径规划方法。
图3是本发明提供的吊装路径规划方法的流程示意图。
如图3所示,本实施例提供的吊装路径规划方法,执行主体可以是车载控制器,也可以是远程控制终端等,主要包括以下步骤:
301、确定吊装路径的起点和终点。
具体的,在进行路径规划时,首先要确定出起重机工作的起点和终点,即吊装路径的起点和终点。通常,吊装起点是确定的,或者可以直接根据定位系统获取到。因此,在具体实现过程中,无需输入起点数据,可以直接输入终点数据,也就是只需确定出吊装路径的终点即可。而确定吊装终点的方式,可以是直接读取用户输入的终点数据,也可以是用户指定位置后,自动定位出终点的位置,只要能够有效地获取到吊装路径的起点和终点即可。
302、输入起点的坐标和终点的坐标至吊装路径规划模型,输出吊装规划路径为最优的吊装路径,吊装路径规划模型为根据上述任一实施例的吊装路径规划模型构建方法得到的。
具体的,在获取到吊装路径的起点和终点之后,便可以将起点数据和终点数据输入至吊装路径规划模型,吊装路径规划模型便会根据起点和终点进行路径规划计算,输出吊装规划路径。
其中,吊装路径规划模型规划起点到终点之间的吊装路径的过程,可以理解为,吊装路径规划模型首先规划出上车路径,然后再规划出下车路径,再将上车路径与下车路径结合,最终得到吊装规划路径。通过分组规划上车路径和下车路径,能够有效地降低数据处理量,提高数据处理速度。吊装路径规划指的是在起点和终点之间选择最为合适的实现路径,在当前作业场景内构建的吊装系统位形空间模型,可以理解为纵横交错的网格,通过A星算法可以快速地完成对每个网格节点的遍历,搜寻出最合适的路径,完成吊装路径规划,例如最终完成的吊装路径规划,为吊装用时最短的路径。其中,随着数据量的增长,A星算法的运算效率会有所降低。
需说明的是,在同一种起重机同一作业场景内,进行吊装路径规划时,只需要获取到吊装路径的起点和终点即可。而当起重机发生变化,或者是作业场景发生变化时,便需要重新构建吊装系统位形空间模型,以重新构建吊装路径规划模型,从而保证路径规划的准确性。
进一步的,在上述实施例的基础上,输出吊装规划路径之后,还可以包括:分别针对上车栅格图数据和下车栅格图数据,从起点开始搜索上车栅格图数据节点和下车栅格图数据节点;针对每个上车栅格图数据节点和下车栅格图数据节点,确定已行代价和预测代价;标记已行代价和预测代价于开启列表中,在开启列表中搜索总代价最小的节点,作为新的起点开始搜索,直至搜索至终点。
具体的,在完成吊装路径规划之后,还需要对吊装路径规划模型输出的吊装路径进行校准修正。修正的方式可以是分别校准上车路径和下车路径,分别针对上车栅格图数据和下车栅格图数据,从起点开始向周围搜索,确定出每个上车栅格图数据节点和下车栅格图数据节点,然后针对每个上车栅格图数据节点和下车栅格图数据节点,确定已行代价和预测代价,并将已行代价和预测代价于开启列表中,开启列表指的是已经搜索过的节点。然后在开启列表中搜索总代价最小的 节点,作为新的起点开始搜索,重复搜索操作,直至搜索至终点,然后再从开启列表中找到最优路径,作为最终的吊装规划路径,从而便完成了对吊装规划路径的优化校准。
进一步的,在上述实施例的基础上,本实施例中在输出吊装规划路径之后,还可以包括:基于吊装系统位形空间模型,转化吊装规划路径为起重机的动作序列;基于动作序列,生成起重机控制指令。
具体的,在确定出吊装规划路径之后,便需要将其吊装规划路径转化为起重机的动作序列,基于动作序列,生成起重机控制指令,从而控制起重机按照确定的吊装规划路径进行移动,起重机的控制指令控制起重机的各个部分按照吊装规划路径进行动作,最终完成吊装起点至终点的控制,起重机便完成吊装作业,由于吊装路径规划的合理性,便可以有效地提高吊装作业效率。
本发明中通过对起重机动作解耦合,灵活适用于起重机不同的工作模式,提高路径规划模块的计算效率。而且上车和下车的分层处理可以实现位形空间降维;降低了数据量并标准化起重机的位形坐标参数,提高了路径规划算法的性能。
