Description

一种用于实现货物拣选的立体仓库搬运调度系统及方法
本公开要求在2020年07月24日提交中国专利局、申请号为202010722774.0、申请名称为“一种用于实现货物拣选的立体仓库搬运调度系统及方法”的中国专利的优先权,其全部内容通过引用结合在本公开中。
技术领域
本公开涉及仓储物流技术领域,尤其涉及一种用于实现货物拣选的立体仓库搬运调度系统及方法。
背景技术
目前,随着物流业的高速发展,为了提高仓库的运行效率,通常采用诸如自动导引车(Automated Guided Vehicle,AGV)等自动化搬运设备,用于实现对货物的自动化运输。同时,由于仓库占地面积通常有限,土地的取得成本和使用成本较高,为了尽可能提高空间使用率,降低运行成本,现有仓库也会采用密集存储的方式存放货物。
现有技术中,为了能够同时解决自动化运输提高效率,以及密集存储降低成本两个问题,设计有一种密集存储仓库使用的四向穿梭车(以下简称四向车)以及四向车运行的专用仓库,如图1a~1b所示。图1a为仓库的剖视图,可见仓库每层包含数个相邻的存储货物的货位,其中穿插有若干供四向车搬运货物的巷道,并且每层货架包括供四向车行驶的轨道,每个货位上设置托放载具的支架,货位间共用立柱支撑。图1b为仓库俯视图,可见货物通过密集堆放,可以节省大量空间,而通过体型较小的四向车可以灵活在各货位间穿行,托运载具上的货物运输到货位,或者将货物运输至仓库的接驳点出库。
但是,四向车属于成本较高的搬运设备,并且必须在轨道上行驶,使得采用四向车存取货物的仓库中,由于轨道的设置使仓库布局难以灵活改 变,仓库建设以及使用成本较高。

具体实施方式
为使本说明书的目的、技术方案和优点更加清楚,下面将结合本说明书具体实施例及相应的附图对本公开技术方案进行清楚、完整地描述。显然,所描述的实施例仅是本公开一部分实施例,而不是全部的实施例。基于本说明书中的实施例,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,都属于本公开保护的范围。
以下结合附图,详细说明本公开各实施例提供的技术方案。
图2为本说明书实施例提供的用于实现货物拣选的立体仓库搬运调度系统的示意图,该系统包括:一个或多个控制中心100、一个或多个第一搬运设备102、一个或多个第二搬运设备104,至少一个立体仓库106以及至少一个升降设备108,并且立体仓库106设置有多层,并由至少一个升降设备108该立体仓库106联通各层,控制中心100分别与第一搬运设备102和第二搬运设备104通信。其中,立体仓库106可划分为底层以及若干高层。底层上设置的货位为底层货位,各高层上设置的货位为高层货位。图2中为了方便理解,仅包含了一个控制中心100,以及一个立体仓库106。
由于仓库存储货物的目的是通过集中存储多种大量货物,例如,方便根据订单需要拣选出所需货物,而本说明书提供的系统中立体仓库的货物是由载具承载的,而载具需要通过第一搬运设备102、第二搬运设备104以及升降设备108来运输,因此在本说明书中的搬运任务也是为了实现货物拣选,并且可由控制中心100根据订单确定。
具体的,在立体仓库进行货物分拣时,需要先根据需要分拣的货物,确定货物存放的货位,然后通过各设备执行搬运任务,使货物出库到达分拣区,并进行分拣,之后在分拣完成后再将剩余货物入库存储,实现货物的分拣。于是,在本说明书中的搬运任务,是为了实现货物分拣而执行的 将载有货物的载具进行搬运的任务。
在货物分拣时,该控制中心100用于根据接收到的订单,确定订单包含的各货物所在的货位,之后确定从货位到达底层接驳点110的路径,再根据路径确定执行搬运任务的第一搬运设备102、第二搬运设备104以及升降设备108,分别向所述第一搬运设备102、第二搬运设备104和升降设备108发送用于执行该搬运任务的搬运指令,在货物在分拣区分拣完成后,控制中心100可再根据载具所在的底层接驳点110,以及货物需要存放的货位位置,确定从底层接驳点110到达货位的路径,根据路径确定执行搬运任务的第一搬运设备102、第二搬运设备104以及升降设备108,分别向所述第一搬运设备102、第二搬运设备104和升降设备108发送用于执行该搬运任务的搬运指令,经上述过程立体仓库完成货物分拣。
另外,还需要说明的是,本说明书中的实现货物拣选的立体仓库及相关方法不仅适用于在仓储场景下商品货物的拣选,也同样适用于工厂生产场景下的成品、半成品或半加工品等货物的拣选,拣选出的货物用于实现某个生产环节或用于某个生产节点。本说明书对货物拣选的应用场景不做具体限定。于是,在本说明书中,立体仓库106的底层设置有至少一个底层接驳点110,底层中的至少部分底层货位布置有载具114和载具支架116中的至少一种,底层货位中的载具支架116用于放置由第二搬运设备104搬运的载具114。其中,载具支架116可根据需要安装在底层货位中,或者从底层货位中移除,当选择不同的底层货位安装载具支架116时,可以在底层行程不同的放置载具114的区域,放置载具114的区域之间的空位可作为巷道,供第二搬运设备104承载载具114时通行。载具支架116用于第二搬运设备104放置载具114,第二搬运设备104将盛放货物的载具114放置于底层货位的载具支架116上,也就是将该货物存放入库。
另外,该立体仓库106的底层接驳点110为与立体仓库106外的对接的接驳点,例如,叉车或者其他搬运设备可从底层接驳点110取出需要出 库的载具114,或者将需要入库的载具114搬运至底层接驳点110,再由第一搬运设备102、第二搬运设备104以及升降设备108中的至少一种,根据控制中心100发送的搬运指令,将载具114从底层接驳点110搬运至底层货位或者高层货位。
在本说明书中,该载具114用于承载货物,但对于载具114具体形式本说明书不做限定,例如,该载具114可以是托盘、料箱等等,只要可以容纳或者承托货物即可。
另外,立体仓库106除底层外的其它高层中的各高层设置有至少一个高层接驳点112,各高层分别设置有供第一搬运设备102运行的轨道118,并且高层中的至少部分高层货位布置有载具114。各高层中的每个高层货位上设置有用于放置载具114的结构,例如支撑杆、托板等等。
进一步地,在本说明书中,立体仓库106各层布置的载具114上可以盛放有仓库存储的货物,或者闲置的其他载具114。每层货位的占用率,即布置有载具114的货位与总货位数量之比,可根据需要配置。则高层的高层货位的占用率可在0~100%之间设置,底层的底层货位的占用率可在0~100%之间设置。
更进一步地,由于立体仓库的106的中的加强筋和横梁等结构,以及货位中已经存放的载具114,使第一搬运设备102或第二搬运设备104在承托载具114时无法从一个货位直接行驶到相邻的另一个货位,因此立体仓库106的各层中均设置有巷道,用于第一搬运设备102或第二搬运设备104在承托载具114时通行。
本说明书提供的图3为立体仓库的俯视示意图,其中,左侧为高层的示意图,可见该高层中包含轨道118,使第一搬运设备102可在轨道118上行驶,右侧为底层的示意图,可见底层不包含轨道118。并且,在俯视图中可见该立体仓库106每层都设置有巷道,用于第一搬运设备102或第二搬运设备104通行。
另外,需要说明的是在本说明书中,不同层的巷道布局可以不完全相同,具体可根据需要设置。其中,由于密集存储式仓库中若需要搬运不与巷道相邻的货位中的货物,需要先将与巷道相邻的货位中的货物搬运出来,使与巷道相邻的货位称为临时巷道,再由搬运设备将不与巷道相邻的货位中的货物搬运出来,因此通常为了搬运效率考虑,不与巷道相邻的货位和与其相邻的巷道旁的货位中存放的货物的库存保有单位(Stock keeping Unit,SKU)相同。此时,仓库中货位与巷道的排列顺序为:1巷道、4货位、1巷道,如图4a所示,既可以增加货物存储密度,也不影响仓库运行效率。
但是,当单一的SUK没有足够多的货物需要两个以上的货位进行存储时,图4a所示的布局则可能影响仓库运行效率,因此通常可以采用图4b所示的布局,也就是仓库中货位与巷道的排列顺序为:1巷道、2货位、1巷道。
在本说明书中,立体仓库每层都可以采用,如图4a或图4b所示的布局,或者两种布局混用的方式进行布局,本说明书对此不做限定。并且,还可根据存放货物的需求,每层采用不完全相同的布局。例如,A层存储的是大件商品,占用空间较大,单一的SUK便有足够多的货物需要两个以上的货位进行存储,则A层可以全部采用图4a的布局,而A+1层存储的是小件商品,则A+1层可以全部采用图4b的布局。
在本说明书中,该第一搬运设备102具体可以是在轨道上行驶的搬运设备,例如,四向穿梭车,该第二搬运设备104具体可以是在平面上行驶的搬运设备,例如,AGV。当然,本公开对于第一搬运设备102和第二搬运设备104的具体形式不作限制,具体可根据需要设置,只要第一搬运设备102可以沿轨道行驶,并搬运高层货位中的载具114,第二搬运设备104可以在底层行驶,并搬运底层货位中的载具114即可。
当控制中心100根据订单确定需要执行的搬运任务时,该控制中心100 可先确定待执行的搬运任务,并根据该搬运任务,确定执行搬运任务的第一搬运设备102,并向第一搬运设备102发送搬运指令。
则第一搬运设备102可根据控制中心100发送的搬运指令,在高层货位中取出或放入搬运指令指示的载具114,以及在高层货位与高层接驳点1102之间搬运搬运指令指示的载具114。
第二搬运设备104可根据控制中心100发送的搬运指令,在底层货位中取出或放入搬运指令指示的载具114,以及在升降设备108与底层货位之间、底层货位与底层接驳点110之间或在升降设备108与底层接驳点110之间搬运搬运指令指示的载具114。立体仓库106的底面是第二搬运设备104行驶的平面,该底面具体可以是立体仓库106所在位置的地面,或者是立体仓库106底层设置的用于第二搬运设备104行驶的平台,例如在立体仓库106底层钢制的平台,用于第二搬运设备104行驶。
升降设备108用于根据控制中心100发送的搬运指令上升或下降至指定层,并在各层之间至少搬运搬运指令指示的载具、第一搬运设备和第二搬运设备中的一种或多种的组合。
其中,指定层即为执行搬运任务时,升降设备108所需到达的层,例如,从3层搬运载具114至底层,则控制中心100可分别发送两个搬运指令至升降设备108,搬运设备108根据第一次接收的搬运指令到达3层(即,第一次接收的搬运指令指示的指定层),当载具114已经搬运至该升降设备108中时,搬运设备108可以根据第二次接收的搬运指令到达底层(即,第二次接收的搬运指令指示的指定层)。当然,上述仅为一种示例,上述举例过程中该控制中心100也可仅发送一个搬运指令,则指定层按照顺序分别为3层以及底层,使升降设备108根据搬运指令先后达到3层以及底层,将3层的载具114搬运至底层。
另外,在本说明书中,高层中的至少部分高层货位还布置有用于放置载具的载具支架114,该载具支架114与前述底层货位不止的载具支架114 相同,具体如何布置已经经过说明,在此不再赘述。
并且,在本说明书中,高层货位中设置的载具支架116,或者,高层货位上设置的用于放置载具114的结构,与轨道118之间的距离大于第一搬运设备102在未承载载具114时的高度,使得第一搬运设备102可驶入高层货位下方,并从高层货位的下方以背驮方式搬运载具114并离开高层货位。
在本说明书提供的一个实施例中,以从任一高层货位中搬运载具114至底层接驳点110进行货物出库的过程为例,对立体仓库搬运调度系统执行搬运任务的过程进行说明。
该立体仓库搬运调度系统的控制中心100根据待执行的搬运任务,当确定需要将位于高层货位的货物搬运至底层接驳点110出库时,首先,可确定该高层货位所在层的各第一搬运设备102。
之后,从确定出的各第一搬运设备102中确定执行该搬运任务的第一搬运设备102,并发送搬运指令。其中,该控制中心100可以根据各第一搬运设备102是否空闲,或者待执行搬运指令的数量,从各第一搬运设备102中确定执行该搬运任务的第一搬运设备102。
当然,本公开对于采用何种策略选择第一搬运设备102不做限制,具体可根据需要设置,例如该控制中心100可简单的从各空闲的第一搬运设备102中任选一个第一搬运设备102,作为执行该搬运任务的第一搬运设备102。或者进一步的,从各空闲的第一搬运设备102中确定距离该搬运任务的货物所在的高层货位最近的第一搬运设备102,作为执行该搬运任务的第一搬运设备102。
并且,控制中心100在向第一搬运设备102发送搬运指令时,还可以异步向升降设备108发送搬运指令,使升降设备108上升或下降至至该高层货位所在层(即指定层),也就是该搬运任务的载具114所在层。则升降设备108可根据该搬运指令移动至该层,等待第一搬运设备102将载具114 搬运至高层接驳点112,并通过高层接驳点112接收载具114。需要说明的是,在本说明书中该控制中心100向不同的搬运设备发送的搬运指令不完全相同。
然后,第一搬运设备102在根据接收到的搬运指令,经所在层的巷道行驶至该搬运任务的载具114所在的高层货位下方,并以背驮的方式从高层货位中搬运出载具114,并再次经所在层的巷道行驶至所在层的高层接驳点112处,通过高层接驳点112将载具114放置于升降设备108中。并在放置完成后,向控制中心100发送搬运指令执行完毕的信息。
需要说明的是,该向第一搬运设备102发送的搬运指令包含有需要搬运的高层货位的标识,高层接驳点112的标识,以及从高层货位到达高层接驳点112的路径,当该立体仓库106包含多个高层接驳点112时,控制中心100可通过路径优化确定高层接驳点112的标识以及路径,作为第一搬运指令包含的信息,发送至第一搬运设备102。使第一搬运设备102按照优化后的路径搬运载具114至高层接驳点112。
控制中心100根据该第一搬运设备102发送的搬运指令执行完毕的信息,确定该升降设备108已经通过高层接驳点112取得载具114,并根据当前搬运的载具114对应的搬运任务,向该升降设备108发送搬运指令,该搬运指令包含有该升降设备108下一步需要达到的指定层,以该示例为例指定层为底层。
则升降设备108可根据控制中心100再次发送的搬运指令,确定将当前搬运的载具114运至立体仓库106的底层,并向控制中心100发送搬运指令执行完毕的信息。
控制中心100根据升降设备108发送的搬运指令执行完毕的信息,确定载具114已经运送至底层。之后,可从各第二搬运设备104中确定执行搬运任务的第二搬运设备104,并向确定出的第二搬运设备104发送搬运指令。其中,从各第二搬运设备104中确定执行搬运任务的第二搬运设备104 的逻辑,可以与从各第一搬运设备102中确定执行该搬运任务的第一搬运设备102的逻辑相同,本说明书对此再赘述。
第二搬运设备104根据控制中心100发送的搬运指令,经底层的巷道行驶至升降设备108处,并搬运该升降设备108搬运的载具114。之后,再次经底层的巷道行驶至底层接驳点110处,将载具放置于底层接驳点110上,并向控制中心100发送搬运指令执行完毕的信息。
最后控制中心100可根据第二搬运设备104发送的执行完毕的信息,确定该搬运任务执行完毕。
其中,底层接驳点110中也可包含载具支架116,该载具支架116可以是输送机形式的,并且可与输送线相连,使第二搬运设备104运输至接驳点110的货物可以沿输送线运输至指定区域(如,拣货区域,或者打包区域等)。
最后,控制中心100在接收到第三搬运指令执行完毕的信息后,确定货物被正确的运输至接驳点110,搬运任务执行完毕。
在本说明书的另一实施例中,当需要出库的货物位于底层货位时,该控制中心100可从各第二搬运设备104中确定执行搬运任务的第二搬运设备104,并向确定出的第二搬运设备104发送搬运指令。
第二搬运设备104根据接收到的搬运指令,经底层的巷道行驶至底层货位处,并搬运底层货位存放的载具114。
之后,第二搬运设备104再次经底层的巷道行驶至底层接驳点110处,将载具放置于底层接驳点110处,并向控制中心100发送搬运指令执行完毕的信息。
最后,控制中心100在接收到第二搬运设备104发送的搬运指令执行完毕的信息后,确定载具114被正确的搬运至底层接驳点110,搬运任务执行完毕。
在本说明书提供的一个实施例中,以从底层接驳点110搬运载具114 至任一高层货位进行入库的过程为例,对用于实现货物拣选的立体仓库搬运调度系统执行搬运任务的过程进行说明。
首先,该系统的控制中心100根据待执行的搬运任务,当确定需要将已经运输至底层接驳点110的载具114搬运至高层货位入库时,首先,可从各第二搬运设备104中确定执行搬运任务的第二搬运设备104,并向确定出的第二搬运设备104发送搬运指令。当然,确定执行搬运任务的第二搬运设备104的逻辑,本说明书不再赘述。
之后,第二搬运设备104根据接收到的搬运指令,经底层巷道行驶至接底层节驳点110处搬运载具114,并再次经底层的巷道行驶至升降设备108处,将载具放置于升降设备108上。并在放置完成后,向控制中心100发送搬运指令执行完毕的信息。
并且,控制中心100在向第二搬运设备104发送搬运指令时,还可以异步向升降设备108发送搬运指令,使升降设备108移动至底层(即指定层),也就是底层接驳点110所在层。则升降设备108可根据该搬运指令移动至底层,等待第二搬运设备104搬运载具114至升降设备108处。
控制中心100在接收到第二搬运设备104发送的搬运指令执行完毕的信息后,可根据搬运指令执行完毕的信息以及搬运任务包含的货物需要存放的高层货位所在层,继续向升降设备108发送搬运指令,该搬运指令对应的指定层为货物需要存放的高层货位所在层。
升降设备108根据再次接收到的控制中心100发送的搬运指令,将载具114运至高层货位所在层,并向控制中心100发送搬运指令执行完毕的信息。另外,该升降设备108在到达指定层时,还可通过高层接驳点112将载具114运出该升降设备108。
控制中心100根据升降设备108发送的搬运指令执行完毕的信息,从该高层货位所在层的各第一搬运设备102中确定执行搬运任务的第一搬运设备102,并向确定出的第一搬运设备102发送搬运指令。
第一搬运设备102根据接收到的搬运指令,经所在层的巷道行驶至高层接驳点112处,搬运升降设备108从底层提升上来的载具114,并再次经所在层的巷道行驶至高层货位下方,将载具114放置于高层货位处。
最后,第一搬运设备102在放置载具114后,可向控制中心100发送搬运指令执行完毕的信息,控制中心100在接收到该第一搬运设备102发送的搬运指令执行完毕的信息后,确定载具114被正确的运输至高层货位,搬运任务执行完毕。
进一步地,在本说明书中,第一搬运设备102可以采用多种方式从高层货位中搬运出载具114或者存放载具114。
具体的,控制中心100根据搬运任务,确定搬运任务对应的高层货位,例如,载具114入库的高层货位,可视为搬运任务对应的高层货位,或者确定将载具114入库存放时的高层货位,也可视为搬运任务对应的高层货位。
之后,控制中心100可根据高层货位的位置以及高层货位相邻的巷道位置,向确定出的第一搬运设备102发送搬运指令。
则第一搬运设备102可根据控制中心100发送的搬运指令,在与高层货位相邻的轨道位置,从高层货位的侧方取出载具114至该第一搬运设备102上,或者,将第一搬运设备102上搬运的载具114从高层货位的侧方放入高层货位中。如图5所示。图5为本说明书提供的第一搬运设备从侧方取放载具的示意图,第一搬运设备102位于高层货位相邻的巷道位置,从高层货位侧方取放货物。
或者,控制中心100在确定搬运任务对应的高层货位后,根据高层货位的位置以及高层货位的上方的其他货位的位置,向确定出的第一搬运设备102发送搬运指令。
则第一搬运设备102可根据控制中心100发送的搬运指令,从高层货位的上方取出载具114至第一搬运设备102中,或者,从第一搬运设备102 中将载具114从高层货位的上方放入至高层货位中。
更进一步地,在本说明书中,第二搬运设备104也可以采用多种方式从底层货位中搬运出载具114或者存放载具114。
具体的,控制中心100根据搬运任务,确定搬运任务对应的底层货位,例如,载具114入库的底层货位,可视为搬运任务对应的底层货位,或者确定将载具114入库存放时的底层货位,也可视为搬运任务对应的底层货位。
之后,控制中心100可根据底层货位的位置以及底层货位相邻的巷道位置,向确定出的第二搬运设备104发送搬运指令。
则第二搬运设备104可根据控制中心100发送的搬运指令,在与底层货位相邻的巷道位置,从底层货位的侧方取出载具114至该第二搬运设备104上,或者,将第二搬运设备104上搬运的载具114从底层货位的侧方放入底层货位中。
或者,控制中心100在确定搬运任务对应的底层货位后,根据底层货位的位置,向确定出的第二搬运设备104发送搬运指令。
则第二搬运设备104可根据控制中心100发送的搬运指令,在底层货位相邻的巷道位置,进入底层货位的下方,从底层货位的下方取出载具114至第二搬运设备104上,或者从第二搬运设备104上将搬运指令指示的载具114放入底层货位中。
另外,在本说明书中,由于针对每个立体仓库106,该立体仓库106中可设置有至少一个升降设备108,因此为了使载具114可以放置于该立体仓库106的任一层,当立体仓库106中包含多个升降设备108时,多个升降设备108所能到达的指定层之间至少存在重叠。
也就是通过重叠的层,各升降设备108可以实现联通该立体仓库106的各层。如图6所示,其中,该立体仓库106一共有4层,以及3个升降设备108分别联通,底层与1层、1层与2层、2层与3层。当然,各升降 设备108可位于立体仓库106的不同位置。
控制中心100可通过一个或多个升降设备108,将载具运输至该立体仓库106中的任一层。例如,上述图6中,若想将3层的货物运输至底层,则控制中心可以分别调用1~3层的第一搬运设备102以及相应的升降设备108,使各升降设备108和各层的第一搬运设备102,以接力的形式将货物从3层运输至底层。
在本说明书中的升降设备108中可以设置有轨道118,使得升降设备108内的轨道118可以与立体仓库106的高层中设置的轨道118连接,则第一搬运设备102在高层沿轨道移动时,可以行使至升降设备108内,并直接将载具114放置于升降设备108内,或者由升降设备108将该第一搬运设备102搬运至其他层。如图7所示。
更进一步地,在本说明书中,当升降设备108中也设置有的轨道118时,该控制中心100还可通过升降设备108将第一搬运设备102在从不同层之间调用。
具体的,在本说明书中,控制中心100可根据部分高层或者所有高层对应的待执行的搬运任务,确定各高层所需的第一搬运设备102的数量。其中,控制中心100可将搬运任务涉及到的高层货位所在的层,作为与搬运任务对应的高层。例如,A搬运任务需要从3层搬运出载具114,则3层就是对应该A搬运任务的高层,或者B搬运任务需要将载具114搬运至3层中的某个高层货位,则3层就是对应该B搬运设备人的高层。另外,该控制中心100可根据各高层对应的待执行的搬运任务的多少,确定各高层所需的第一搬运设备102的数量,当高层对应的待执行的搬运任务越多,则该高层所需的第一搬运设备102的数量越多。当然,由于仓库中每层空间有限,数量过程的第一搬运设备102可能导致设备可行驶路径减少或者路径拥堵,因此在本说明书中该控制中心100还可根据预设的每层高层的第一搬运设备102的最大数量,确定各高层所需的第一搬运设备102的数 量。其中,该第一搬运设备102的最大数量可以根据每层布局的不同而不同,当高层中布置的载具114的数量越少时,说明第一搬运设备102可通行的区域越多。
之后,控制中心100可根据各高层所需的第一搬运设备102的数量和当前各高层的第一搬运设备102的数量,确定各高层需要调用的第一搬运设备102,并发送调用指令给需要调用的第一搬运设备102。
则第一搬运设备102还用于,根据接收到的控制中心100发送的调用指令,沿轨道118行驶至升降设备108内,通过升降设备108到达调用指令指定的高层。
另外,在本说明书上述对立体仓库106的结构描述中,各高层分别设置的高层接驳点112都是独立在升降设备108外的,这是由于若第一搬运设备102无法到达升降设备108内,需要由高层接驳点112将载具114运至升降设备108内,再由升降设备108将载具114搬运至指定层。
而若升降设备108内也设置有轨道118,并且第一搬运设备102可以驶入升降设备108内,则在本说明书中也可将高层接驳点112设置为位于升降设备108内。
于是第一搬运设备102进一步用于,根据控制中心100发送的搬运指令,行驶至升降设备108内的高层接驳点112处,将载具114放置于高层接驳点112,或者,从高层接驳点112的取出载具114。
进一步地,在本说明书中,由于仓库建设时可能会受到各方面的影响,导致每层布局不同,而当立体仓库106的高层中存在无法由轨道连通的所有区域的层时,如图8所示,若需要在两个区域间调用第一搬运设备102,则该控制中心100可用于:
针对无法由轨道118连通的所有区域的层,当需要在该层的不同区域间调用第一搬运设备102时,将调出第一搬运设备102区域作为出发区,将调入第一搬运设备102区域作为目的区,控制中心100用于确定距离该 层最近的由轨道连通的所有区域的层,作为中间层。
控制中心100向出发区中的第一搬运设备102发送调用指令、向联通中间层与出发区的升降设备108发送搬运指令以及向联通中间层与目的区的升降设备108发送搬运指令,使第一搬运设备102通过两个升降设备108以及中间层的轨道116后,从出发区到达目的区。
更进一步地,本说明书提供的系统中,当存在两个以上的立体仓库106时,各立体仓库106的底面互相连通。如图9a和图9b所示。其中,图9a为对应图8的两立体仓库地面互相连通的简单示意图,表示两个立体仓库只有底层由于连通,因此可视为是一个整体,图9b为详细示意图,可见两个立体仓库是独立分别在底面上设置的。
并且控制中心100可根据至少部分立体仓库106对应的待执行的搬运任务,确定各立体仓库106所需的第一搬运设备102的数量。
根据各立体仓库106所需的第一搬运设备102的数量和当前各立体仓库106的第一搬运设备102的数量,确定各立体仓库106需要调用的第一搬运设备102。
将调出第一搬运设备102的立体仓库106作为出发仓库,将调入第一搬运设备102的立体仓库106作为目的仓库,并向出发仓库中的第一搬运设备102发送调用指令、向第二搬运设备104、出发仓库的升降设备108以及目的仓库的升降设备108发送搬运指令,使第一搬运设备102通过两个升降设备108以及第二搬运设备104从出发仓库调用至目的仓库。
其中,第二搬运设备104还用于,根据调用指令从出发仓库的底层将第一搬运设备102搬运至目的仓库的底层。
需要说明的是,由于第一搬运设备102可通过轨道行驶至升降设备108内,因此第二搬运设备104可将升降设备108内的第一搬运设备102视为是升降设备108内的载具114,并以搬运载具114相同的方式,将第一搬运设备102从升降设备108内搬运出来。而且由于各立体仓库106的底层是 联通,因此第二搬运设备104可以通过底层从一个立体仓库106到达另一个立体仓库106,实现第一搬运设备102的在不同立体仓库106间的调用。
另外,在本说明书中,升降设备108内设置有无动力的移载设备120或有动力的移载设备120,高层接驳点112至少包括位于升降设备内的移载设备120。其中,有动力的移载设备120可主动移动至于移载设备120上的载具114,例如,辊筒线、运输线、双向伸缩叉等等,具体形式不限,而无动力的移载设备120至少可包括用于放置载具114的载具支架116。
第一搬运设备102进一步用于,行驶至所述升降设备108内的作为高层接驳点112的移载设备处120,将载具114放置于所述移载设备120上,或者,从作为高层接驳点112的移载设备120上取出载具114。
进一步地,在本说明书中,立体仓库106的各高层中至少部分的在升降设备108与高层对接的位置外设置有无动力的移载设备120或有动力的移载设备,120。则本说明书中的高层接驳点还至少包括位于升降设备外的移载设备。如图10所示。
当升降设备108位于高层时,位于升降设备108外的移载设备120与位于升降设备108内的移载设备120对接,并将载具114从升降设备108内的移载设备120上输送至升降设备108外的移载设备120上,或者,将载具114从位于升降设备108外的移载设备120上的输送至升降设备108内的移载设备120上。
需要说明的是,在本说明书中当升降设备108内外的移载设备120均为无动力的移载设备120时,该第一搬运设备102可以是从侧方取出或存放载具114的方式,将载具114推送至移载设备120上。当升降设备108内外的移载设备120中任一为有动力的移载设备120时,可以通过该有动力的移载设备120推动载具114。
另外,在本说明书中,立体仓库106的底层的指定区域设置有至少一个底层接驳点110,也就是说底层接驳点110也可以是至底层中的指定的一 块区域。
于是,第二搬运设备104用于从底层货位或升降设备108中取出载具114,并将载具114搬运至底层接驳点110,将载具114放置于指定区域内。或者,从指定区域的底层接驳点110取出载具114,并将载具114搬运至底层货位或升降设备108。
由于底层货位可以设置有用于放置载具114的载具支架116,并且载具支架116与底层的之间的最小距离可以高于第二搬运设备104的高度,因此底层货位的载具支架116通常与底层存在高度差。同理,升降设备108由于要从高层接驳点112获取货物,而高层接驳点112的高度与第一搬运设备102适配,因此升降设备108通常与底层也存在高度差。
于是,当底层接驳点110是位于底层的一块指定区域时,第二搬运设备104中需设置有具有提升载具114和放置载具114的装置,例如可以提升降低的货叉,使得第二搬运设备104可以从底层的指定区域将载具114搬运至高度不同的底层货位或升降设备108中。
进一步地,在本说明书中,在升降设备108内置有移载设备120时,该立体仓库106的底层也可设置有动力的移载设备120,以便当升降设备108位于底层时,底层的移载设备120与位于升降设备108内部的移载设备120对接,用于将载具114从升降设备108内的移载设备120输送至底层的移载设备120上,使得第二搬运设备104可从底层的移栽设备120中取出载具114,或者,第二搬运设备104在将载具114放置于底层的移栽设备120时,该底层的移载设备120可将载具114从底层的移载设备120输送至升降设备108内的移载设备120上。
于是,本说明书中的第二搬运设备104进一步用于,从底层的移载设备120上取出载具114,并将载具搬运至底层接驳点112,并将载具114放置于指定区域内。或者,第二搬运设备104可从指定区域的底层接驳点112取出载具114,并将载具114搬运至底层的移载设备120上。如图11所示, 虚线表示了载具114移动路径。
进一步地,在本说明书的另一种实施方式中,控制中心100可以根据需要,向第二搬运设备104发送运输至该立体仓库106之外的指定区域的搬运指令,则该第二搬运设备104可以根据搬运指令,将载具114搬运至指定区域。也就是说,在本说明书中不限制第二搬运设备104仅能在立体仓库106内运行,第二搬运设备104由于是在底层的平台上运行的,因此不受轨道的限制,可以更灵活的与系统外或者立体仓库106外的设备对接,以运出载具114或者运入载具114。其中外部的设备可以是工作人员控制的叉车、输送载具114的辊筒线、生产线、工作人员分拣货物的区域等等,本说明书对此不做限制。
更进一步地,该系统还可包括:至少一个外部缓存区,该外部缓存区形式为立体存储或平面存储中的至少一种,本说明书对此不做限定。当该外部缓存区为立体存储形式时,该外部缓存区中也可设置有升降设备108,用于联通外部缓存区各层。当然,若该外部缓存区没有设置升降设备108,也可通过立体搬运设备,如叉车等,搬运外部缓存区中高层的载具114,并且,该外部缓存区的布局结构也可为上述图2~4b所示的形式。
在本说明书中,外部缓存区可与立体仓库106共用各第二搬运设备104,该第二搬运设备104在外部缓存区与至少一个立体仓库106之间搬运载具114,或接驳载具114。例如,则当需要将立体仓库106中的货物搬运至外部缓存区时,控制中心100可向第二搬运设备发送搬运指令,则可由该第二搬运设备104将载具114运输至外部缓存区缓存。
当然,当该外部缓存区为平面存储形式时,该外部缓存区也可以是由设置于地面的载具支架116组成的缓存区域,该外部缓存区可用于盛放货物中出库入库频率较高的货物,减少立体仓库106的在就114出库入库的频率,降低入库频率较高的货物在搬运时占用的各搬运设备的时间。通常 来说,该外部缓存区相对于该立体仓库106的存储量更小,结构更加简单,只要能实现货物的缓存即可,因此如前所述可以仅由设置于地面的载具支架116组成。
基于图2所示的用于实现货物拣选的立体仓库搬运调度系统,以及上述搬运任务执行过程的描述,可见本说明书提供的系统,通过在立体仓库混合使用第一搬运设备以及第二搬运设备,利用立体仓库中的升降设备搬运功能,使得第一搬运设备和第二搬运设备可协作在密集存储仓库中搬运货物,避免了在仓库底层铺设轨道,使得仓库布局可以灵活改变,并可减少第一搬运设备需求数量,降低了仓库运行成本,实现了搬运效率的提升。
另外,在本说明书中,为了增加第二搬运设备104在未搬运载具114时路径选择的灵活度,立体仓库106的底层中的至少部分底层货位的载具支架116的高度高于第二搬运设备104在未承载载具114时的高度。
第二搬运设备104进一步用于,在未承载载具114时可选择行地在至少部分底层货位下方穿行,或者,从至少部分底层货位的下方以背驮方式搬运载具114。
进一步地,立体仓库106的底层中的至少部分底层货位间立柱的间隔大于第二搬运设备104的宽度,以及,立体仓库106的底层中至少部分相邻的两根立柱之间的连接件的最低点的高度高于第二搬运设备102在未承载载具114时的高度。第二搬运设备102进一步用于,在未承载载具114时可选择性地在底层中至少部分相邻的两根立柱之间穿行。
基于图2所示的系统,本说明书还提供一种立体仓库搬运调度方法,如图12所示。
图12为本说明书提供的立体仓库搬运调度流程示意图,立体仓库至少存在一个或多个,立体仓库至少由一个升降设备连通立体仓库的各层,立体仓库的底层设置有至少一个底层接驳点,底层中的至少部分底层货位布置有载具和载具支架,底层货位中的载具支架用于放置由第二搬运设备搬 运的载具,立体仓库除底层外的其它高层中的各层分别设置有至少一个高层接驳点,高层分别设置有供第一搬运设备运行的轨道,并且高层中至少部分高层货位布置有载具,该搬运流程具体可包括以下步骤:
S200:确定待执行的搬运任务。
需要说明的是,该搬运任务是用于立体仓库实现货物分拣,使搬运设备搬运载具的任务,可根据接收到的订单确定。
S202:根据所述搬运任务,确定执行搬运任务的第一搬运设备、第二搬运设备以及升降设备。
S204:向确定出的所述第一搬运设备、第二搬运设备和升降设备分别发送搬运指令,使所述第一搬运设备、第二搬运设备和升降设备配合将载具从所述立体仓库的高层货位或底层货位中搬运至底层接驳点,或将底层接驳点的载具搬运至所述立体仓库的高层货位或底层货位中。
本说明书提供的搬运方法具体可以由控制中心执行,该控制中心可以是一台货或者多台设备,例如由多台服务器组成的分布式服务器,本说明书对此不做限定,当然由于立体仓库可以是一个或多个,可以设置一个控制中心确定多个立体仓库的搬运任务,并调度设备执行搬运任务,或者也可由多个控制中心分别确定不同的搬运任务,并调度设备执行搬运任务。并且,当有多个控制中心时,各控制中心可共享确定的搬运任务,以便多个控制中心可协同完成多个搬运任务。
另外,该方法的详细执行过程可参考上述用于实现货物拣选的立体仓库搬运调度系统中对于执行搬运任务的过程的描述,本说明书对此不再赘述。
进一步地,在本说明书中,以控制中心执行该搬运调度流程为例说明,由于该第一搬运设备可以从高层货位的上方或者侧方搬运载具,因此在向确定出的第一搬运设备发送搬运指令,使第一搬运设备执行搬运任务时,控制中心可根据搬运任务,确定搬运任务对应的高层货位,根据高层货位 的位置以及高层货位相邻的巷道位置,向确定出的第一搬运设备发送搬运指令,使第一搬运设备根据搬运指令,在巷道位置从高层货位的侧方取出搬运指令指示的载具至第一搬运设备上,或者使第一搬运设备根据搬运指令,从第一搬运设备上将搬运指令指示的载具从侧方放入高层货位中。
其中,与高层货位相邻的巷道位置,为与高层货位之间没有立体仓库的加强结构(如,加强筋)或者,隔板等仓库结构的巷道位置,由于巷道为用于第一搬运设备搬运载具时行驶的通道,第一搬运设备需要从高层货位搬运出载具,沿巷道行驶,因此每个高层货位与相邻巷道之间必定存在一条没有格挡的通路。当然,如上述系统中所述的立体仓库平面布局可以有多种,则至少通过搬运其它载具,也可使任一高层货位与巷道连通。
或者,控制中心可根据搬运任务,确定搬运任务对应的高层货位,根据高层货位的位置以及高层货位的上方的其他货位的位置,向确定出的第一搬运设备发送搬运指令,使第一搬运设备根据搬运指令,在高层货位的上方的其他货位的位置,从高层货位的上方取出搬运指令指示的载具至第一搬运设备中,或者使第一搬运设备根据搬运指令,从第一搬运设备中将搬运指令指示的载具下放至高层货位上。
另外,在本说明书中由于该第二搬运设备也可采用不同方式从底层货位取出货物,如以从底层货位的下方或者侧方搬运载具,因此在向确定出的第二搬运设备发送搬运指令,使第二搬运设备执行搬运任务时,控制中心可根据搬运任务,确定搬运任务对应的底层货位,根据底层货位的位置以及底层货位相邻的巷道位置,向第二搬运设备发送搬运指令,使第二搬运设备在底层货位相邻的巷道位置,从底层货位的侧方取出搬运指令指示的载具至第二搬运设备上,或者使从第二搬运设备上将搬运指令指示的载具从侧方放入底层货位中。
进一步地,控制中心还可根据搬运任务,确定搬运任务对应的底层货位,根据底层货位的位置,向第二搬运设备发送搬运指令,使第二搬运设 备在底层货位相邻的巷道位置,进入底层货位的下方,从底层货位的下方取出搬运指令指示的载具至第二搬运设备上,或者使从第二搬运设备上将搬运指令指示的载具放入底层货位中。
另外,若升降设备内设置有轨道,用于与高层中设置的轨道连接,使第一搬运设备行驶至升降设备内。
控制中心还可至少部分地根据各高层待执行的搬运任务,确定各高层所需的第一搬运设备的数量,并根据各高层所需的第一搬运设备的数量和当前各高层的第一搬运设备的数量,确定各高层需要调用的第一搬运设备。之后,向确定出的需要调用的第一搬运设备发送调用指令,使第一搬运设备还根据接收到的调用指令,行驶至升降设备内,通过升降设备到达调用指令指定的高层。
进一步地,若高层接驳点设置为位于升降设备内,控制中心在向第一搬运设备发送搬运指令时,可根据搬运任务,确定搬运任务对应的升降设备内的高层接驳点,并根据升降设备内的高层接驳点的位置,向确定出的第一搬运设备发送搬运指令,使第一搬运设备行驶至升降设备内的高层接驳点处,将载具放置于高层接驳点,或者,从高层接驳点的位置取出载具。
更进一步地,升降设备内设置有无动力的移载设备或有动力的移载设备,高层接驳点至少包括位于升降设备内的移载设备。则控制中心可根据搬运任务,确定搬运任务对应的升降设备内的高层接驳点。根据升降设备内的高层接驳点的位置,向确定出的第一搬运设备发送搬运指令,使第一搬运设备行驶至升降设备内的作为高层接驳点的移载设备处,将载具放置于移载设备,或者,从作为高层接驳点的移载设备上取出载具。
并且,当升降设备外还设置无动力的移载设备或有动力的移载设备时,高层接驳点还至少包括位于升降设备外的移载设备,则控制中心还可根据搬运任务,确定搬运任务对应的高层接驳点,根据高层接驳点所在层,向升降设备发送搬运指令,使升降设备在高层接驳点所在层,通过位于升降 设备外部的移载设备与位于升降设备内部的移载设备对接,将载具从升降设备内的移载设备输送至升降设备外作为高层接驳点的移载设备,或者将位于升降设备外作为高层接驳点的移载设备上的载具输送到升降设备内的移载设备上。
另外,在本说明书中,该立体仓库的底层接驳点为立体仓库与外界接驳载具的区域,而若立体仓库外是叉车等可以从底层叉取载具的设备,则可以在立体仓库的底层的指定区域设置有至少一个底层接驳点。控制中心在向确定出的第二搬运设备发送搬运指令时,还可根据搬运任务,确定搬运任务对应的指定区域设置的底层接驳点,根据指定区域设置的底层接驳点,向第二搬运设备发送搬运指令,使第二搬运设备从底层货位或升降设备取出搬运指令指示的载具,并将载具搬运至底层接驳点,将载具放置于指定区域内,或者,从指定区域的底层接驳点取出搬运指令指示的载具,并将载具搬运至底层货位或升降设备。
进一步地,升降设备内还可设置有动力的移载设备,相应的则立体仓库的底层地面设置有动力的移载设备,控制中心在控制升降设备搬运载具时,可以根据搬运任务,确定搬运任务对应的底层接驳点,并向升降设备发送搬运至底层的搬运指令,使升降设备移动至底层,底层地面的移载设备与位于升降设备内部的移载设备对接,将载具从升降设备内的移载设备输送至底层的移载设备,或者将底层地面的移载设备上的载具输送到升降设备内的移载设备上。
在上述情况下,载具在底层从升降设备中运出至底层的移载设备上,则控制中心可根据搬运任务,确定搬运任务对应的指定区域设置的底层接驳点,根据指定区域设置的底层接驳点,向第二搬运设备发送搬运指令,使第二搬运设备从底层地面的移载设备上取出载具,并将载具搬运至底层接驳点,将载具放置于指定区域内,或者,当第二搬运设备是要将载具运输至升降设备,有升降设备提升至其他层时,第二搬运设备根据接收到的 搬运指令,可从指定区域的底层接驳点取出搬运指令指示的载具,并将载具搬运至底层地面的移载设备上
另外,若立体仓库的高层中存在无法由轨道连通所有区域的高层,针对无法由轨道连通的所有区域的高层,当控制中心确定需要在该高层的不同区域间调用第一搬运设备时,如,前述系统中所述的需要根据执行搬运任务的需要调用第一搬运设备时,则控制中心可将调出第一搬运设备区域作为出发区,将调入第一搬运设备区域作为目的区,并确定距离该高层最近的由轨道连通所有区域的其他高层,作为中间层。并向出发区中的第一搬运设备发送调用指令、向连通中间层与出发区的升降设备发送搬运指令以及向连通中间层与目的区的升降设备发送搬运指令,使第一搬运设备通过两个升降设备以及中间层,从出发区到达目的区。
更进一步地,当立体仓库包括包含两个以上时,在本说明书中各立体仓库的底面互相连通,控制中心若确定需要在不同立体仓库间调用第一搬运设备,则可将调出第一搬运设备的立体仓库作为出发仓库,将调入第一搬运设备的立体仓库作为目的仓库。
并向所述出发仓库中的第一搬运设备发送调用指令、向第二搬运设备、所述出发仓库的升降设备以及所述目的仓库的升降设备发送搬运指令,使所述第一搬运设备通过所述两个升降设备以及所述第二搬运设备从所述出发仓库调用至所述目的仓库。
另外,在本说明书提供的另一实施例中,在立体仓库外设置一个或多个外部缓存区,外部缓存区的形式为立体存储或平面存储。外部缓存区与立体仓库共用至少部分第二搬运设备,或,第二搬运设备在外部缓存区与至少一个立体仓库之间搬运和/或接驳载具。
则控制中心在确定待执行的搬运任务时,可根据存储外部缓存区与立体仓库中的货物库存信息,以及订单信息,确定待执行的搬运任务。也就是说需要考虑外部缓存区存储的货物,以及外部缓存区存储货物的能力。
基于图12所示的方法,通过在立体仓库混合使用第一搬运设备以及第二搬运设备,利用立体仓库中的升降设备搬运功能,使得第一搬运设备和第二搬运设备可协作在密集存储仓库中搬运货物,避免了在仓库底层铺设轨道,使得仓库布局可以灵活改变,并可减少第一搬运设备需求数量,降低了仓库运行成本,实现了搬运效率的提升。
在20世纪90年代,对于一个技术的改进可以很明显地区分是硬件上的改进(例如,对二极管、晶体管、开关等电路结构的改进)还是软件上的改进(对于方法流程的改进)。然而,随着技术的发展,当今的很多方法流程的改进已经可以视为硬件电路结构的直接改进。设计人员几乎都通过将改进的方法流程编程到硬件电路中来得到相应的硬件电路结构。因此,不能说一个方法流程的改进就不能用硬件实体模块来实现。例如,可编程逻辑器件(Programmable Logic Device,PLD)(例如现场可编程门阵列(Field Programmable Gate Array,FPGA))就是这样一种集成电路,其逻辑功能由用户对器件编程来确定。由设计人员自行编程来把一个数字系统“集成”在一片PLD上,而不需要请芯片制造厂商来设计和制作专用的集成电路芯片。而且,如今,取代手工地制作集成电路芯片,这种编程也多半改用“逻辑编译器(logic compiler)”软件来实现,它与程序开发撰写时所用的软件编译器相类似,而要编译之前的原始代码也得用特定的编程语言来撰写,此称之为硬件描述语言(Hardware Description Language,HDL),而HDL也并非仅有一种,而是有许多种,如ABEL(Advanced Boolean Expression Language)、AHDL(Altera Hardware Description Language)、Confluence、CUPL(Cornell University Programming Language)、HDCal、JHDL(Java Hardware Description Language)、Lava、Lola、MyHDL、PALASM、RHDL(Ruby Hardware Description Language)等,目前最普遍使用的是VHDL(Very-High-Speed Integrated Circuit Hardware Description Language)与Verilog。本领域技术人员也应该清楚,只需要将方法流程用上述几种硬件 描述语言稍作逻辑编程并编程到集成电路中,就可以很容易得到实现该逻辑方法流程的硬件电路。
控制器可以按任何适当的方式实现,例如,控制器可以采取例如微处理器或处理器以及存储可由该(微)处理器执行的计算机可读程序代码(例如软件或固件)的计算机可读介质、逻辑门、开关、专用集成电路(Application Specific Integrated Circuit,ASIC)、可编程逻辑控制器和嵌入微控制器的形式,控制器的例子包括但不限于以下微控制器:ARC 625D、Atmel AT91SAM、Microchip PIC18F26K20以及Silicone Labs C8051F320,存储器控制器还可以被实现为存储器的控制逻辑的一部分。本领域技术人员也知道,除了以纯计算机可读程序代码方式实现控制器以外,完全可以通过将方法步骤进行逻辑编程来使得控制器以逻辑门、开关、专用集成电路、可编程逻辑控制器和嵌入微控制器等的形式来实现相同功能。因此这种控制器可以被认为是一种硬件部件,而对其内包括的用于实现各种功能的装置也可以视为硬件部件内的结构。或者甚至,可以将用于实现各种功能的装置视为既可以是实现方法的软件模块又可以是硬件部件内的结构。
上述实施例阐明的系统、装置、模块或单元,具体可以由计算机芯片或实体实现,或者由具有某种功能的产品来实现。一种典型的实现设备为计算机。具体的,计算机例如可以为个人计算机、膝上型计算机、蜂窝电话、相机电话、智能电话、个人数字助理、媒体播放器、导航设备、电子邮件设备、游戏控制台、平板计算机、可穿戴设备或者这些设备中的任何设备的组合。
为了描述的方便,描述以上装置时以功能分为各种单元分别描述。当然,在实施本说明书时可以把各单元的功能在同一个或多个软件和/或硬件中实现。

这些计算机程序指令也可存储在能引导计算机或其他可编程数据处理设备以特定方式工作的计算机可读存储器中,使得存储在该计算机可读存储器中的指令产生包括指令装置的制造品,该指令装置实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能。
这些计算机程序指令也可装载到计算机或其他可编程数据处理设备上,使得在计算机或其他可编程设备上执行一系列操作步骤以产生计算机实现的处理,从而在计算机或其他可编程设备上执行的指令提供用于实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能的步骤。
在一个典型的配置中,计算设备包括一个或多个处理器(CPU)、输入/输出接口、网络接口和内存。
内存可能包括计算机可读介质中的非永久性存储器,随机存取存储器(RAM)和/或非易失性内存等形式,如只读存储器(ROM)或闪存(flash RAM)。内存是计算机可读介质的示例。
计算机可读介质包括永久性和非永久性、可移动和非可移动媒体可以由任何方法或技术来实现信息存储。信息可以是计算机可读指令、数据结构、程序的模块或其他数据。计算机的存储介质的例子包括,但不限于相变内存(PRAM)、静态随机存取存储器(SRAM)、动态随机存取存储器(DRAM)、其他类型的随机存取存储器(RAM)、只读存储器(ROM)、电可擦除可编程只读存储器(EEPROM)、快闪记忆体或其他内存技术、只读光盘只读存储器(CD-ROM)、数字多功能光盘(DVD)或其他光学存储、磁盒式磁带,磁带磁磁盘存储或其他磁性存储设备或任何其他非传输介质,可用于存储可以被计算设备访问的信息。按照本文中的界定,计算机可读介质不包括暂存电脑可读媒体(transitory media),如调制的数据信号和载波。
还需要说明的是,术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含,从而使得包括一系列要素的过程、方法、商品或者设备不仅包括那些要素,而且还包括没有明确列出的其他要素,或者是还包括为这种过程、方法、商品或者设备所固有的要素。在没有更多限制的情况下,由语句“包括一个……”限定的要素,并不排除在包括所述要素的过程、方法、商品或者设备中还存在另外的相同要素。
