物品拣选调度请求的处理方法及相关设备

技术领域
本申请涉及物流技术领域，更具体地，是物品拣选调度请求的处理方法及相关设备。
背景技术
仓库等物品存储空间内，一般设置有多个物品拣选区域。通常地，不同的物品拣选区域内存放的物品类型不同。例如，仓库内设置有3个拣选区域，拣选区域A存放有食品，拣选区域B存放有饮料，拣选区域C存放有日用品。
通常地，待拣选的物品会来自不同的拣选区域，为了提高物品拣选效率，可以在物品存储空间内布置驱动装置如移动机器人，以及布置物品承载装置如拣选车，移动机器人可以为物品承载装置提供驱动力，以使物品承载装置从一个拣选区域运动至另一拣选区域，物品承载装置在到达每个拣选区域后可以装载从该拣选区域拣选出的物品。
具体地，物品拣选的过程为，接收到调度请求后，根据与调度请求相关的拣选资源的状态信息，状态信息如驱动装置的占用情况、拣选车的占用情况等，生成调度任务。其中，拣选资源的状态信息包含在上下文容器中，调度系统每当接收到一个调度请求，便需要根据上下文容器中的状态信息生成调度任务。但是上下文容器中的状态信息可能会更新，若调度请求需要的状态信息被更新，便会影响该调度请求的处理过程，使得调度请求的处理过程出错。

具体实施方式
下面将结合本申请实施例中的附图，对本申请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申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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，都属于本申请保护的范围。
仓库等物品存储空间内，设置有多个位置不同的拣选区域。物品拣选是从一个或多个存储区域获得物品，并将物品运送到指定区域。为了提高物品拣选效率，可以在物品存储空间内布置至少一个驱动装置如移动机器人，以及布置至少一个物品承载装置如拣选车。物品承载装置主要用于，承载从拣选区域中拣选出来的物品，驱动装置主要用于为物品承载装置提供驱动力，使得物品承载装置可以去往各个拣选区域的位置点或其他位置点。另外，为了给驱动装置补充能源，在物品存储空间内还设置有至少一个能源桩，能源桩如充电桩，驱动装置运行至能源桩可以补充能源。
通过以上对应用场景的说明可知，物品存储空间内部署有驱动装置、物品承载装置等各种拣选设备。为了实现物品拣选，需要对拣选设备生成调度任务，根据拣选任务进行调度。调度指的是对拣选设备的指派并控制，主要包括：控制哪个驱动装置去哪个位置点，以驱动位于该位置点的物品承载装置，以及驱动装置如何从当前位置点到达该位置点；在驱动装置没电的情况下，需要去往哪个位置点的能源桩补充能源，以及如何从当前位置点到达该位置点；一个物品承载装置需要去往哪几个拣选区域，以装载从这些拣选区域拣选出来的物品，等等。
需要说明的是，调度任务是根据拣选资源的状态信息生成的，拣选资源可以包括拣选设备及拣选设备所需要工作在的物品存储空间的布局情况。拣选资源的状态信息可以包括但不局限于，物品承载装置是否空闲、物品承载装置的位置点、驱动装置是否空闲、驱动装置的位置点、能源补给装置是否空闲、能源补给装置的位置点、驱动装置是否需要充电、物品承载装置是否装载完毕、物品存储空间的布局地图等等。其中布局地图中可以包含关键位置点信息，关键位置点可以包括但不局限于交叉道路的位置、拣选区域的位置点等。
对拣选设备的调度包括多种类型，不同类型的调度需要的状态信息不同，所有的状 态信息都保存在上下文容器中。但写入进程接收到拣选资源的状态信息后，会向上下文容器中写入状态信息，从而可能更新上下文容器中的状态信息。若在一次调度请求的处理过程中，调度请求使用的状态信息发生变化，会导致本次调度请求的出错。
因此，为了避免出现以上问题，本申请提供了一种物品拣选调度请求的处理方法。如图1所示，该物品拣选调度请求的处理方法包括步骤S101～S103。
S101：接收到与物品拣选相关的调度请求后，确定调度请求对应的目标拣选资源状态信息。
其中，本方法的执行装置可以接收调取请求，调度请求可以是外部设备发送的，也可以调度系统内部生成的。例如，驱动装置可以向本方法的执行装置发送请求充电的调度请求。又如，调度系统包括本方法的执行装置及控制装置，控制装置根据监测到的各个拣选设备的状态，确定某个物品承载装置需要从某个位置点去往另一位置点装载物品，则向本方法的执行装置发送调度请求。
接收到调度请求后，本方法的执行装置首先需要确定该调度请求需要使用哪些拣选资源状态信息。为了便于描述，这些拣选资源状态信息可以称为目标拣选资源状态信息。
拣选资源状态信息可以存储在存储容器中，在一个具体实现方式中，拣选资源状态信息存储在上下文容器中，则可以在上下文容器中，确定与调度请求对应的目标拣选资源状态信息。需要说明的是，上下文容器中除了可以存储拣选资源状态信息，还可以存储配置信息，例如工作状态中的驱动装置的能源下限及补充能源时所补充的能源的上限。上下文容器中还可以存储调度任务，调度任务可以以文件或者数据库的形式存在。上下文容器中还可以记录调度过程出现的异常信息及错误。
具体地，为了确定出每种类型的调度请求对应的拣选资源状态信息，需要预先设置调度请求的类型与其所需要的拣选资源状态信息的对应关系。例如，一种类型的调度请求为为驱动装置补充能源，则该种类型的调度请求需要的拣选资源状态信息包括但不局限于：驱动装置的位置、所有能源补充装置的位置、所有能源补充装置的占用情况、物品存储空间的道路布局。又如，一种类型的调度请求为将物品承载装置由一个位置点驱动至另一位置点，则该种类型的调度请求需要的拣选资源状态信息包括但不局限于：物品承载装置的位置点、所有驱动装置的位置、所有驱动装置的占用情况、物品存储空间的道路布局。再如，一种类型的调度请求为为空闲的驱动装置分配驱动物品承载装置的任务，则该种类型的调度请求需要的拣选资源状态信息包括但不局限于：所有物品承载装置的拣选任务完成进度、空闲的驱动装置的位置、所有物品承载装置的位置、物品存 储空间的道路布局。当然，以上仅仅是示例说明，调度请求的类型及调度请求需要的拣选资源状态信息并不局限于此，还可以根据实际需求为其他内容。
基于以上预设的、调度请求的类型与拣选资源状态信息的对应关系，确定目标拣选资源状态信息的方式是，确定调度请求的类型，根据所述对应关系确定所述类型对应的拣选资源状态信息，该拣选资源状态信息对应的状态即目标拣选资源状态信息。
S102：生成目标拣选资源状态信息的镜像信息。
其中，目标拣选资源状态信息表示的是拣选资源当前的状态信息，若目标拣选资源的状态发生变化，会实时反映到目标拣选资源状态信息中。例如，目标拣选资源状态信息中包含驱动装置的电量，随着时间的推移，驱动装置的电量会不断减少，因此目标拣选资源状态信息中驱动装置的电量会不断变化。又如，目标拣选资源状态信息中包含驱动装置的忙闲状态，驱动装置可能在确定目标拣选资源状态信息时为空闲状态，但马上又被人工设置成为了忙碌状态，驱动装置会立即向目标拣选资源状态信息发生修改指令，将目标拣选资源状态信息中的该项信息修改为忙碌。当然，目标拣选资源状态信息的变化并不局限于上述两种，还可以是其他。
总结来看，由于使用目标拣选资源状态信息生成调度任务是需要一段时间的，如果目标拣选资源状态信息在这个时间段内发生变化，则会使调度任务的生成过程出现错误。因此，需要在确定目标拣选资源状态信息后，复制目标拣选资源状态信息，得到目标拣选资源状态信息的镜像信息。
在一个具体实现方式中，目标拣选资源状态信息保存在上下文容器中，可以复制上下文容器中的目标拣选资源状态信息，生成上下文容器镜像，并将复制的目标拣选资源状态信息存储在上下文镜像中。需要说明的是，上下文容器镜像中的拣选资源状态信息只是用于对步骤S101的调度请求进行处理，以生成调度任务。状态写入进程更新上下文容器中的拣选资源状态信息，不会影响上下文容器镜像中的目标拣选资源状态信息。
不同的调度请求所需要的拣选资源状态信息可能不同，接收到一个调度请求后，便为该调度请求生成对应的上下文容器镜像。另外，上下文容器镜像也可以称为调度窗口。
S103：根据目标拣选资源状态信息的镜像信息，生成物品拣选的调度任务。
其中，目标拣选资源状态信息的镜像信息是根据调度请求确定出来的，因此，直接使用镜像信息便可以为调度请求生成调度任务。调度任务与调度请求是相关的，调度任务的内容是对调度请求的处理内容。
例如，调度请求为给某个驱动装置补充能源，则调度任务为控制该驱动装置沿着某 行进路线到某个能源补给装置进行充电。又如，调度请求为将某个物品承载装置驱动至某个位置点，则调度任务为为该拣选车确定某个空闲的驱动装置，并控制该驱动装置将该物品承载装置驱动至该某个位置点。
需要说明的是，不同的调度请求，生成调度任务的方式不同。以上述所举的三种调度请求为例，说明调度任务的生成过程。
例如，调度请求为为驱动装置补充能源，且目标拣选资源状态信息包括：驱动装置的位置、所有能源补充装置的位置、所有能源补充装置的占用情况、物品存储空间的道路布局。则生成调度任务时，根据驱动装置的位置、所有能源补充装置的位置及所有能源补充装置的占用情况，确定出距离驱动装置最近的且未被占用的能源补充装置，并根据物品存储空间的道路布局，生成行进至该驱动装置行进至该能源补充装置的运动路线。
又如，调度请求为将物品承载装置由一个位置点驱动至另一位置点，且目标拣选资源状态信息包括：物品承载装置的位置点、所有驱动装置的位置、所有驱动装置的占用情况、物品存储空间的道路布局。则生成调度任务时，根据物品承载装置的位置点、所有驱动装置的位置及所有驱动装置的占用情况，确定出距离该物品承载装置最近且空闲的驱动装置，并根据物品存储空间的道路布局，生成驱动装置将物品承载装置从一个位置点驱动至该另一个位置点的运动路线。
再如，调度请求为为空闲的驱动装置分配驱动物品承载装置的任务，且目标拣选资源状态信息包括：所有物品承载装置的拣选任务完成进度、空闲的驱动装置的位置、所有物品承载装置的位置、物品存储空间的道路布局。则生成调度任务时，根据所有物品承载装置的拣选任务完成进度、所有物品承载装置的位置及空闲的驱动装置的位置，确定出距离空闲的驱动装置最近且拣选任务的完成进度为已完成的物品承载装置，并根据物品存储空间的道路布局，生成空闲的驱动装置行进至该物品承载装置的运动路线。
当然，以上调度任务的生成方式仅仅是示例说明，不同的调度请求的目标拣选资源状态信息不同，生成调度任务的方式也不同。在实际应用中，可以使用调度算法的求解器、指派算法求解器及充电排班求解器等处理模块，对调取请求进行处理。
需要说明的是，生成调度任务后，可以对目标拣选资源状态信息进行更新。例如，调度任务是为某个驱动装置分配驱动某个物品承载装置的任务，则该驱动装置的拣选资源状态信息由空闲改为工作中，且目标拣选资源状态信息中包含该驱动装置与该物品承载装置的对应关系。以目标拣选资源状态信息在上下文容器中为例，对目标拣选资源状态信息的更新指的是更新上下文容器中的目标拣选资源状态信息。
由于调度任务是根据目标拣选资源状态信息的镜像生成的，然而目标拣选资源状态信息可能在拣选任务生成过程中发生变化，为了避免生成的调度任务在执行过程中发生错误，在下发调度任务之前，对调度任务关联的拣选资源的状态信息进行检查，检查拣选资源状态信息与调度任务是否存在冲突，若存在冲突则删除该调度任务。例如，调度任务为使用驱动装置1将物品运载装置从位置A驱动至位置B，在生成调度任务时，与该调度任务关联的驱动装置1的电量高于预设阈值，但是在调度任务下发之前检查时驱动装置1的电量低于预设阈值，则为了避免调度错误则将该调度任务删除。
需要说明的是，拣选资源状态信息与调度任务之间的冲突指的是预设的不能及时完成调度任务的冲突，如上述驱动装置电量低于预设阈值，则需要耗费较长时间补充电量，又如驱动装置由空闲状态变为忙碌状态。对于某些情况本方法并未将其预设为冲突情况。例如，驱动装置的位置在调度任务计算时为A点，但调度任务下发时为B点，A点与B点相隔不远，或者驱动装置在B点相比A点距离需要驱动的物品运载装置更近，则可以仍下发该调度任务，使位于B点的驱动装置去执行调度任务。又如，驱动装置需要驱动的物品运载装置的位置由C点变为D点，但C点与D点相隔不远，或者物品运载装置在D点相比A点距离驱动装置更近，则仍可以下发该调度任务，以使驱动装置驱动位于D点的物品运载装置。
由以上技术方案可知，本申请提供了一种物品拣选调度请求的处理方法，该方法在接收到调度请求后，确定与调度请求对应的拣选资源状态信息，并生成拣选资源状态信息的镜像，进而使用拣选资源状态信息的镜像来生成调度任务。这样，即使拣选资源状态信息被更新，并不会影响拣选资源状态信息的镜像信息，从而避免了拣选资源状态信息更新对调度请求的影响。
为了方便理解上述处理过程，结合图2所示的上下文容器进行说明。图2示出了本申请提供的物品拣选调度请求的处理过程示意。如图2所示，上下文容器中的方框表示拣选资源状态信息。接收到调度请求后，从上下文容器中选择该调度请求需要的拣选资源状态信息，并将选择的拣选资源状态信息复制至上下文容器镜像中，使用上下文容器镜像中的拣选资源状态信息，生成调度任务。
在实际应用中，以上步骤S101中接收到与物品拣选相关的调度请求后，且在确定目标拣选资源状态信息之前，如图3所示，还可以包括：对调度请求的检查步骤。
具体地，检查与物品拣选相关的调度请求是否存在错误；若调度请求存在错误，则 根据错误的类型生成对应的错误信息，并返回错误信息；若调度请求不存在错误，才执行确定调度请求对应的目标拣选资源状态信息步骤。
其中，接收到的调度请求可能存在错误，不同的调度请求包含的错误内容及导致错误的原因可能不同。例如，调度请求是驱动装置发送的，调度内容为请求执行驱动任务，该驱动装置的能源可能在设置的能源下限，并不能进入工作状态。又如，某个拣选区域的拣选人员未将该拣选区域的物品完全拣选至物品承载装置，但在物品承载装置上按下完成按钮，则物品承载装置发送调度请求，调度请求内容为将物品承载装置驱动至下一拣选区域的位置。由于拣选人员的误操作，造成调度请求的错误。再如，物品承载装置发送调度请求，调度请求的内容为将物品承载装置驱动至一个拣选区域的位置执行拣选任务，拣选任务为装载从拣选区域拣选出来的物品，但是该物品承载装置并未绑定有拣选任务。
为了保证调度任务的准确性，在生成调度任务之前可以对调度请求进行检查。不同的调度请求检查的内容不同，可以预先设置调度请求所对应的检查内容，接收到调度请求后，根据该对应关系便可以确定该调度请求对应的检查内容。进而根据检查内容对调度请求进行检查。例如，调度请求为驱动装置请求执行驱动任务，需要检查驱动装置是否空闲、能源是否在能源下限以下等。又如，调度请求为物品承载装置需要从某个拣选区域去往另一个拣选区域的位置点执行拣选任务，需要检查物品承载装置是否绑定有拣选任务，是否完成该某个拣选区域的拣选任务等。需要说明的是，以上调度请求及调度请求对应的检查内容均为示例说明，在实际应用中并不局限于此。
如图3所示，若检查发现调度请求存在错误，则将错误信息返回给发送调度请求的装置。进一步地，还可以将错误信息上报至调度系统，以提示系统人员错误。若检查未发现调度请求存在错误，则确定上下文容器并按照上述图1中步骤S102及S103进行调度处理，生成调度任务。
需要说明的是，以上对调度请求的处理可以由调度进程处理。调度系统除了包括调度进程外，还可以包括写入进程，写入进程主要用于更新拣选资源状态信息。例如写入进程向上下文容器中写入拣选资源状态信息，写入即上述更新动作，包括新增、删除及修改等具体动作。在具体实现中，写入进程可以直接接收到的拣选资源状态信息写入上下文容器，也可以对接收到的拣选资源状态信息进行检查，以检查所述拣选资源状态信息中是否包含错误的拣选资源状态信息，若拣选资源状态信息不包含错误的拣选资源状 态信息，则将拣选资源状态信息写入到上下文容器中。
如图4所示的向上下文容器中写入拣选资源状态信息的流程，具体包括步骤S401～S404。
S401：接收拣选资源状态信息。
其中，拣选资源状态信息可以包括但不局限于物品存储空间布局图、物品承载装置的拣选资源状态信息、驱动装置的拣选资源状态信息、驱动装置绑定的拣选任务状态信息。其中拣选任务状态信息可以包括但不局限于，拣选任务包含的物品分别来自于哪些拣选区域。拣选资源状态信息可能是拣选设备发送的，也可以是其他设备发送的，如物品存储空间的布局图可能是调度系统中的地图管理模块发送的，物品承载装置的拣选资源状态信息可能是物品承载装置发送的，驱动装置的拣选资源状态信息可能是驱动装置发送的，驱动装置绑定的拣选任务的拣选资源状态信息可能是调度系统中的某个模块发送的。
S402：检查拣选资源状态信息中是否包含错误的状态信息。
需要说明的是，状态信息类型不同，错误的内容可能不同。对于需要具有两个信息项对应的状态信息，检查状态信息是否包含具有对应关系的两个信息项。
例如，物品承载装置的拣选资源状态信息为工作中，则表示物品承载装置并未空闲，其对应有物品的拣选任务，若在拣选资源状态信息中并未检测到该物品承载装置对应的拣选任务，则认为该拣选资源状态信息为错误的拣选资源状态信息。又如，驱动装置的拣选资源状态信息为工作中，则表示驱动装置为某个物品承载装置占用，若在拣选资源状态信息中并未检测到驱动装置对应的物品承载装置，则认为该拣选资源状态信息为错误的状态信息。当然，以上对拣选资源状态信息及拣选资源状态信息的检查内容仅仅是示例说明，在实际应用中还可以是其他。
需要说明的是，两个信息项出现的错误可能是，仅有一个信息项，如仅有物品承载装置并没有对应的驱动装置或者反之。或者，出现了两个信息项以上的对应。例如，布局地图中的某个拣选区域对应有多个物品承载装置，但可以理解的是，一个位置点并不可能被多个物品承载装置占用，因此这种拣选资源状态信息为错误的状态信息。
S403：若拣选资源状态信息包含错误的状态信息，则标记错误的拣选资源状态信息，并记录错误的内容。
其中，若拣选资源状态信息存储在上下文容器中，则标记为错误的拣选资源状态信息也可以存储到上下文容器中，由于该拣选资源状态信息标记为错误，因此在使用拣选 资源状态信息进行调度时，可以先检查拣选资源状态信息是否存在错误标记，并选择不具有错误标记的拣选资源状态信息。或者，标记为错误的拣选资源状态信息存储在其他容器中，若错误日志文件等。
S404：若拣选资源状态信息不包含错误的状态信息，则将拣选资源状态信息存储到上下文容器中。
由以上技术方案可知，以上提供了一种保存拣选资源状态信息的流程，在保存之前可以对拣选资源状态信息进行检查，发现错误的拣选资源状态信息并进行隔离，从而保证了拣选资源状态信息的正确性，进而保证了使用拣选资源状态信息生成的调度任务的准确性。
以向上下文容器保存拣选资源状态信息为例，写入进程可以向上下文容器中写入拣选资源状态信息，调度进程可以从上下文容器中取出拣选资源状态信息生成调度任务。写入之前及调取之前均可以包含错误检查，以保证调度过程的准确性。
在实际应用中，物品存储空间内部署的驱动装置可能有多个，但驱动装置使用的数据通信格式可能不同，调度系统与各个驱动装置通信时，如发送拣选资源状态信息返回错误信息发送调度请求等时，需要进行通信格式的转换。其中通信格式也可以称为通信协议。
例如，不同型号的驱动装置产自不同的厂家，不同厂家使用的通信格式不同。不同型号的驱动装置的工作原理也可能不同，例如有些型号的驱动装置使用拖拽的方式驱动拣选车，有些型号的驱动装置使用牵引的方式驱动拣选车，有些型号的驱动装置使用顶的方式驱动拣选车。
因此，如图5所示，可以为不同类型的驱动装置设置对应的代理模块，代理模块将驱动装置与调度系统之间的通信格式进行转换，以使通信格式转换为调度系统及驱动装置各自能够识别的通信格式。其中，调度系统可以为物品拣选调度请求的处理设备，或者物品拣选调度请求的处理为调度系统中的一个设备。
基于包括上述代理模块的处理，拣选资源状态信息包括驱动装置发送的拣选资源状态信息，且驱动装置发送的拣选资源状态信息经过驱动装置代理模块的格式转换后，转换为统一格式的拣选资源状态信息；调度请求包括驱动装置发送的调度请求，且驱动装置发送的调度请求经过驱动装置代理模块的格式转换后，转换为统一格式的调度请求。
另外，调度系统还可以设置可视化控制界面，以实时显示驱动装置的运行状态，同时可以接收人工下发的调度指令，以调度驱动装置去驱动物品承载装置或者补充能源。
本申请还提供了物品拣选调度请求的处理设备，用于执行上述物品拣选调度请求的处理方法。见图6，其示出了本申请提供的一种物品拣选调度请求的处理设备的结构，具体包括：通信接口601、存储器602、处理器603及总线604。
