具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、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。
目前，当管理方需要校验物品货架的实际摆放情况是否符合陈列图纸时，须人工进行抽检或者稽查，这导致校验效率非常低，且校验结果的准确性并不高。为了解决现有技术存在的问题，在本申请的一些实施例中：部署于物品货架上的多个电子架签之间，可基于视距通信进行标识信息的传递，各电子架签可将自身的标识信息及接收到的标识信息作为相对位置数据发送至服务器。从而，服务器可获得大量的能够反映各电子架签与其视距范围内的电子架签之间位置关系的相对位置数据，服务器可根据这些相对位置数据确定出多个电子架签之间的实际摆放位置关系，基于此，可判断电子架签之间的实际摆放位置关系是否符合陈列图纸。
以下结合附图，详细说明本申请各实施例提供的技术方案。
图1a为本申请一实施例提供的一种电子架签系统的结构示意图。如图1a所示，该系统包括：服务器11和多个电子架签10。
本实施例中，多个电子架签10之间可采用视距通信进行数据传输。其中，视距通信是指在视距条件下，无线信号无遮挡地在发送端与接收端之间直线传播。电子架签10可与其视距范围内的其它电子架签进行通信。另外，电子架签10还可与服务器11进行通信，其中，电子架签10与服务器11之间可以是无线或有线网络连接。例如，电子架签10与服务器11之间可通过无线访问接入点(AP，Access Point)实现相对位置数据的传输。当然，电子架签10与服务器11之间还可采用其它网络连接方式实现相对位置数据的传输，例如，移动网络等。其中，移动网络的网络制式可以为2G(GSM)、2.5G(GPRS)、3G(WCDMA、TD-SCDMA、CDMA1100、UTMS)、4G(LTE)、4G+(LTE+)、WiMax、5G以及未来的6G或7G等中的任意一种。
图1b为一实施例提供的一种电子架签系统的应用状态示意图。如图1b所述，多个电子架签10部署于物品货架中，以其中的至少一个电子架签为例，每个电子架签10的安装位置可对应物品货架上的一个陈列位置。其中，电子架签10的数量可根据物品货架中所需校验的陈列位置的数量而确定，电子架签10的数量可以是两个或多于两个。多个电子架签10在物品货架上的部署结构可灵活调整。
在一些实际应用中，管理方可利用陈列管理软件的辅助手段，预先设计陈列图纸，从而通过陈列图纸表征出多个电子架签10在物品货架上的部署结构，工作人员可按照陈列图纸进行电子架签10的部署。为了降低操作复杂度，工作人员可按照陈列图纸表征出的多个电子架签10在物品货架上的部署结构，保证在各部署位置上安装上电子架签即可，这样，工作人员无需区分不同的电子架签，也无需进行电子架签与部署位置的配对，大大降低了操作复杂度。当然，本实施例并不限于此，陈列图纸中还可表征出各部署位置配对的电子架签的标识，工作人员可根据各部署位置配对的电子架签的标识，将多个电子架签10安装到各自对应的部署位置上。
图1b中示出了一种示例性的部署结构，在图1b中，物品货架的各陈列位置成排成列分布，电子架签10按照与陈列位置一一对应的方式进行部署，从而，电子架签10的部署结构也是成排和/或成列部署。当然，图1b中示出的部署结构仅是示例性的，电子架签10与陈列位置可以不一一对应，而且，电子架签10也可按照其它部署规则进行部署，例如，可按照隔行部署、隔列部署、星型部署等等规则，本实施例对此不作限定，所需的部署规则可体现在陈列图纸中。值得说明的是，图1b中仅示出了一个物品货架，但这不应造成对本实施例保护范围的限定，本实施例中，物品货架的数量可以是多个，相应地，多个物品货架上均可部署电子架签10。
为了实现视距传输，每个电子架签10中可安装视距通信装置，电子架签10之间可利用视距通信装置进行视距通信，视距通信装置可包含视距发送单元和/或视距收发单元。其中，视距通信装置可以是红外通信装置，当然也可以是其它能够支持视距通信的通信装置，本实施例对此不作限定。
本实施例中，根据硬件结构的不同，各电子架签10可支持的视距通信功能可能不同。
例如，电子架签10上仅配置有视距接收单元时，电子架签10则只能支持视距接收功能。
又例如，电子架签10上仅配置有视距发送单元时，电子架签10则只能支持视距发送功能
又例如，电子架签10上配置有视距接收单元和视距发送单元时，电子架签10则可支持视距收发功能。
据此，按照各电子架签10可支持的视距通信功能的不同，至少可将多个电子架签10划分为以下三类：
第一类电子架签可用于基于视距通信接收视距范围内的第一目标电子架签10发送的标识信息；并将自身的标识信息和第一目标电子架签10的标识信息作为相对位置数据发送至服务器11。
第二类电子架签可用于在触发事件发生时，基于视距通信将自身的标识信息发送给视距范围内的第二目标电子架签10。
第三类电子架签可用于在触发事件发生时，基于视距通信将自身的标识信息发送给视距范围内的第二目标电子架签10，以及基于视距通信接收视距范围内的第一目标电子架签10发送的标识信息；并将自身的标识信息和第一目标电子架签10的标识信息作为相对位置数据发送至服务器11。
在具备了硬件支持的情况下，电子架签之间可进行标识信息的传递。其中，标识信息可以是电子架签的设备标识号、身份编码等等能够体现身份的信息，基于标识信息，可区分不同的电子架签。对于上述的第一类和第三类电子架签来说，其可获取到视距范围内的其它电子架签的标识信息，而获取到的标识信息可有效表征出电子架签之间的相对位置，因此，上述的第一类和第三类电子架签可将其自身的标识信息和接收到的标识信息作为相对位置数据发送至服务器11，以供服务器11确定多个电子架签10之间的相对位置关系。
本实施例中，电子架签10在向服务器11发送相对位置数据时，可对相对位置数据进行加密和签名，而服务器11可直接对相对位置数据进行解析、处理、存储和响应等等操作，从而保证了电子架签10与服务器11之间的所有中间转发设备无法进行窃听、伪造和篡改，安全性高，并发性能好，这为服务器11校验位置关系奠定了数据安全基础。
据此，服务器11可接收到大量的相对位置数据，通过这些相对位置数据，可确定出两两电子架签10之间的相对位置，进而可确定出多个电子架签10之间的实际摆放位置关系，并对多个电子架签10之间的实际摆放位置关系进行校验。在一些实际应用中，服务器11可将陈列图纸中包含的多个电子架签10之间的摆放位置与其确定出的实际摆放位置关系进行比对，从中定位出差异点位，从而筛选出摆放不符合陈列图纸的电子架签10。
另外，服务器11中获取各电子架签10各自关联的至少一个物品的物品信息，并可基于确定出的多个电子架签10之间的实际摆放位置关系及各电子架签10各自关联的至少一个物品的物品信息，生成物品货架中各物品的实际陈列关系，并对物品货架中各物品的实际陈列关系进行校验。在一些实际应用中，前述的陈列图纸中还可包含物品货架上各物品之间的摆放关系，服务器11可将陈列图纸中包含的物品货架上各物品之间的摆放关系与其确定出的各物品的实际陈列关系进行比对，从中定位出差异点位，从而筛选出摆放不符合陈列图纸的物品。
在物品货架上，各物品的陈列方式多种多样，从陈列位置的维度来说，每个陈列位置上可包含至少一个物品，当单个陈列位置上包含多个物品时，这些物品可以属于同一物品类，例如，一个陈列位置上可摆放多瓶A牌牛奶；这些物品也可属于不同物品类，例如，一个陈列位置上可摆放可成对出售的碗和筷子。本实施例对此均不作限定。
据此，在一些实际应用中，电子架签系统中还可包含手持终端，手持终端用于采集物品货架中任意物品的物品信息，包括编码信息、所属类别等等；手持终端还可用于采集各物品所在陈列位置所对应的电子架签10的标识信息，并将物品信息和电子架签10的标识信息关联发送至服务器11。服务器11可据此获取到各电子架签10各自关联的至少一个物品的物品信息，以便在对物品货架进行位置关系校验时，根据多个电子架签10之间的实际摆放位置关系，准确地确定出各物品的实际陈列关系。
本实施例中，部署于物品货架上的多个电子架签10之间，可基于视距通信进行标识信息的传递，从而可获得大量的能够反映各电子架签10与其视距范围内的电子架签10之间位置关系的相对位置数据。这些相对位置数据将被发送到服务器11，服务器11可根据这些相对位置数据确定出多个电子架签10之间的实际摆放位置关系，基于此，可判断电子架签10之间的实际摆放位置关系是否符合陈列图纸。因此，本申请实施例中，可基于视距通信实现电子架签10之间的相互定位，从而准确地确定出电子架签10之间的实际摆放位置关系，进而可实现对物品货架的摆放情况的智能校验和稽查，可有效提高校验效率和准确度。
在上述或下述实施例中，对于各电子架签10来说，其可能在多个方向上支持视距通信功能，为方便描述，将电子架签10上支持视距通信功能的方向描述为数据传输方向，例如，当电子架签10的上、下、左、右四个侧面上均配置有视距通信装置时，则电子架签10可在其上、下、左、右四个数据传输方向上支持视距通信功能。其中，电子架签10在其不同数据传输方向上所配置的视距通信装置可不完全相同，相应地，电子架签10 在不同数据传输方向上可支持的视距通信功能也可不完全相同。
例如，电子架签10的上和下两个侧面上均安装有视距发送单元和视距接收单元，则电子架签10在上和下两个数据传输方向上，均可支持双向通信模式。
又例如，电子架签10的左侧面上仅安装有视距发送单元，则电子架签10在左向的数据传输方向上，则仅可支持单向通信模式。
再例如，电子架签10的右侧面上仅安装有视距接收单元，则电子架签10在右向的数据传输方向上，则仅可支持单向通信模式。
据此，多个电子架签10中任意两个视距范围存在重合的电子架签10之间，可根据各自所支持的视距通信功能，在视距通信过程中，可采用前述的双向通信模式或单向通信模式。
当两个视距范围存在重合的电子架签10中的任一个电子架签10在与对方相对的数据传输方向上仅支持单向通信模式时，该两个电子架签10之间可采用单向通信模式。
在单向通信模式下，两个电子架签10可分为发送方和接收方：发送方可将标识信息发送至接收方；接收方则可接收发送方发送的标识信息，而无需将自身的标识信息回传给发送方。
图2为一实施例提供的一种电子架签系统中多个电子架签10在单向通信模式下的通信状态示意图。图2示出了一个物品货架上部署的多个电子架签10之间的单向通信状态，例如，电子架签A与电子架签B之间的相对侧面上分别配置有视距发送单元tx和视距接收单元rx，仅可支持两者之间采用单向通信模式，因此，电子架签A和B之间，A可作为发送方，B作为接收方，A可将自身的标识信息发送给B，而B可接收A的标识信息。又例如，电子架签D和E之间，E作为发送方，D作为接收方，E可将自身的标识信息发送给D，而D可接收E的标识信息。基于图2所示的单向通信状态，图2中的电子架签D将可获取到电子架签C、I和E的标识信息，而电子架签D则将自身的标识信息分享给电子架签H和F，而并未获取到任何其他电子架签的标识信息。因此，可将图2中的电子架签C归类为前述实施例中的第一类电子架签，将图2中的电子架签G归类为前述实施例中的第二类电子架签，而将其它的电子架签归类为第三类电子架签。
值得说明的是，虽然图2中示出的所有电子架签之间均标示了单向通信路径，但这仅是为了凸显单向通信模式的通信状态，并不应造成对本实施例保护范围的限定。应当理解的是，本实施例中，对于任意一个电子架签10来说，其不同数据传输方向上所采用的视距通信模式可不完全相同，并不局限于图2中示出的在各数据传输方向上都采用单 向传输模式这一种通信状态。
图3为本申请一实施例提供的电子架签系统中任意两个电子架签10之间进行单向通信的过程示意图。
如图3所示，两个电子架签10中包含一个发送方和一个接收方。对于作为发送方的电子架签10来说，可在输出时隙内循环输出自身的标识信息。对于作为接收方的电子架签10来说，可在侦听时隙内启动视距接收功能，以接收发送方发送的标识信息。
其中，发送方的输出时隙的起点为触发事件发生时。触发事件可以是发送方中的预设定位周期到达，也可以是接收到服务器11下发定位指令等等，本实施例对此不作限定，发送方可定时自动启动标识信息的发送操作，也可按照服务器11的相关指令启动标识信息的发送操作。
另外，发送方的输出时隙大于接收方的休眠时隙，而且，发送方的输出时隙不再受电子架签10本身的侦听时隙和休眠时隙的限制。其中，休眠时隙是指电子架签10处于深度休眠状态的时期。本实施例中，为了降低电子架签10的功耗，可在电子架签10中设定定时器，电子架签10可在定时器的定时唤醒之下，定时醒来，进入侦听时隙，在侦听时隙中，电子架签10可接收数据；而在侦听时隙之外的时期即为休眠时隙，在休眠时隙中，电子架签10的电流可达到4uA，比侦听时隙中的电流5mA低3个数量级，因此，电子架签10处于休眠时隙时可有效降低功耗。而且，本实施例中，在满足工作需求的情况下，还可将侦听时隙的长度设定的足够短，例如，侦听时隙的长度可比休眠时隙的长度短2～3个数量级，这可进一步降低电子架签10的整体功耗。
基于此，如图3所示，发送方在输出时隙26s内循环发送自身的标识信息，由于接收方的休眠时隙为25s，因此，可保证接收方至少可在发送方的输出时隙的最后1s之内进入侦听时隙，从而接收方可成功接收到发送方发送的标识信息。
值得说明的是，接收方在侦听到发送方正在向其发送标识信息时，其工作状态可不再受到侦听时隙的控制，也即是，无论侦听时隙是否足够用于完成接收发送方的标识信息的工作，接收方可持续保持在工作状态，直至完成发送方的标识信息的接收工作。
据此，本实施例中，可将标识信息的接收过程压缩在电子架签10正常的活动周期内，标识信息的接收过程不会增加电子架签10在侦听时隙内的功耗，这可有效维持电子架签10持续稳定的低功耗状态。
在发送方和接收方进行标识信息的传递过程中，本实施例并不限定标识信息的信息格式，例如，标识信息可整体携带在一个数据包中进行传递，当然，标识信息还可采用 其它的信息格式进行传递。在一种实现方式中，发送方可将自身的标识信息拆分为N个数据段，N为正整数；按照N个数据段的排列顺序，确定N个数据段各自对应的序列号；根据N个数据段及其各自对应的序列号，分别进行数据编码，以获得N个数据包；将N个数据包发送至接收方。
如图3所示，发送方的标识信息携带在6个数据包中，发送方可在输出间隙内按序循环输出这6个数据包。而接收方进入侦听时隙时，可能首先接收到的是6个数据包中的非首个数据包，图3中接收方在进入侦听时隙时首先接收到的是第1个数据包，此时，接收方可继续接收发送方后续的数据包，也即是第2-6个数据包，直至完成6个数据包的接收工作。对于接收方来说，可根据各数据包中的序列号判断是否完成了全部数据包的接收工作。在完成数据包的接收工作后，接收方可通知发送方接收工作已完成，发送方将停止输出数据包；当然，接收方也可不通知发送方，发送方将在输出时隙结束后停止输出数据包。
图4为一实施例提供的一种数据包的结构示意图。如图4所示，每个数据包中可包含起始位、序列号和数据段。图中以“11”作为起始位，之后是序列号，序列号用于表征当前数据段在标识信息中的位置，序列号之后为数据段。数据包中还可包含奇偶校验位用于校验数据包的完整性。数据包中还可在数据段之后用一空白间隔表征数据包的结束，以实现分段。
图3中两个电子架签10之间进行单向通信的过程中，即采用了如图4所示的数据包结构。在图3中，发送方的标识信息为0X112233445566，发送方将标识信息拆分为6个数据段“11”、“22”、“33”、“44”、“55”和“66”，按照6个数据段的排列顺序，可确定出各数据段对应的序列号，据此，第一个数据包中至少包含的字节有：11000000010001，第二个数据包中至少包含的字节有：11000100100010，同理，其它的数据包不再赘述。
图5为一实施例提供的一种视距通信编码协议示意图。如图5所示，按照图4的数据包结构，电子架签10的视距发送单元可采用PWM脉冲输出，并按照曼彻斯特编码方式进行数据包的发送，也即是以电平的变化表征数据包中的逻辑1和逻辑0，以形成数据流，从而实现数据包的视距传输。当然，本实施例并不限于此。
据此，可实现两个电子架签10之间的单向通信。在单向通信模式下，作为接收方的电子架签10在接收到作为发送方的电子架签10发送的标识信息后，可将其自身的标识信息及接收到的标识信息发送至服务器11。参考图3可知，作为接收方的电子架签10 可能会接收到多个标识信息，例如，图3中的电子架签D可接收到3个标识信息，这种情况下，电子架签D可将接收到的所有标识信息均发送至服务器11。
当两个视距范围存在重合的电子架签10与对方相对的数据传输方向上均支持双向通信模式时，该两个电子架签10之间还可采用双向通信模式。
在双向通信模式下，两个电子架签10之间可相互传递标识信息。
图6为一实施例提供的一种电子架签系统中多个电子架签10在双向通信模式下的通信状态示意图。图6示出了一个物品货架上部署的多个电子架签10之间的双向通信状态，例如，电子架签A与电子架签B之间的相对侧面上均配置有视距发送单元tx和视距接收单元rx，可支持两者之间采用双向通信模式，因此，电子架签A和B之间，A可将自身的标识信息发送给B，而B可接收A的标识信息；同时，B可将自身的标识信息发送给A，而A可接收B的标识信息。基于图6所示的双向通信状态，图6中的电子架签D将可获取到电子架签C、I和E的标识信息，而电子架签D则同时将自身的标识信息分享给电子架签C、I和E。因此，图6中的所有电子架签10都可归类为上述的第三类电子架签。
同样，值得说明的是，虽然图6中示出的所有电子架签之间均标示了双向通信路径，但这仅是为了凸显双向通信模式的通信状态，并不应造成对本实施例保护范围的限定。应当理解的是，本实施例中，对于任意一个电子架签10来说，其不同数据传输方向上所采用的视距通信模式可不完全相同，并不局限于图6中示出的在各数据传输方向上都采用双向传输模式这一种通信状态。
另外，本实施例中，为了提高电子架签系统对不同应用场景的适应性，视距范围存在重合的两个电子架签10之间所采用的视距通信模式，可基于电子架签系统中各电子架签10之间的实际摆放位置关系以及各电子架签10所支持的视距通信模式而自动确定，例如，在实际摆放关系中，电子架签a和电子架签b的视距范围存在重合，若两者相对侧面上的硬件结构仅能支持单向通信模式，则两者之间自动采用单向通信模式；若两者相对侧面上的硬件结构可支持双向通信模式，则两者之间自动采用双向通信模式；而若两者相对侧面上的硬件结构无法支持任何通信模式，例如，两者相对侧面上均配置的是视距接收单元，则两者之间无法进行视距通信。当然，本实施例并不限于这种自动确定视距通信模式的实现方式，本实施例中，还可在陈列图纸中标示出各电子架签在各数据传输方向上的视距通信模式，工作人员可按陈列图纸进行电子架签的安装，以使各电子架签按照陈列图纸中标示出的视距通信模式进行通信；还可通过服务器向各电子架签发 送模式控制指令的方式，按需调整各电子架签在不同数据传输方向上的视距通信模式，等等。
图7为本申请一实施例提供的电子架签系统中任意两个电子架签10之间进行双向通信的过程示意图。
如图7所示，可将两个电子架签10中的任意一个设定为发起方，而将另一个设定为响应方。对于发起方来说，可在触发事件发生时，在输出时隙内循环输出信息交互请求，直至接收到响应方发出的同意指示，并在接收到响应方发出的同意指示时，与响应方交换标识信息。而对于响应方来说，可在侦听时隙内启动视距接收功能，以接收发送方发送的信息交互请求；并在接收到信息交互请求时，向发起方发送的同意指示，以与发起方交换标识信息。
其中，发起方的输出时隙的起点为触发事件发生时。触发事件可以是发起方中的预设定位周期到达，也可以是接收到服务器11下发定位指令等等，本实施例对此不作限定，发起方可定时自动启动信息交互请求的发送操作，也可按照服务器11的相关指令启动信息交互请求的发送操作。
另外，发起方的输出时隙大于响应方的休眠时隙，而且，发起方的输出时隙不再受电子架签10本身的侦听时隙和休眠时隙的限制。关于电子架签10的侦听时隙和休眠时隙的相关描述可参考前文，在此不再赘述。
基于此，如图6所示，发起方在输出时隙26s内循环发送信息交互请求，由于响应方的休眠时隙为25s，因此，可保证响应方至少可在发起方的输出时隙的最后1s之内进入侦听时隙，从而响应方可成功接收到发起方发送的信息交互请求。响应方在接收到发起方的信息交互请求时，可向发起方回传同意指示，从而建立起双方之间的标识信息交换通道，双方可利用标识信息交换通道进行标识信息的交换。
值得说明的是，当发起方和响应方建立起标识信息交换通道后，发起方的工作状态可不再受到输出时隙的限制，响应方的工作状态也可不再受到侦听时隙的限制。也即是，无论发起方的输出时隙、响应方的侦听时隙是否足够用于完成接收发送方的标识信息的工作，双方都可持续保持在工作状态，直至完成标识信息的交换。
据此，本实施例中，可将标识信息的接收过程压缩在电子架签10正常的活动周期内，标识信息的接收过程不会增加电子架签10在侦听时隙内的功耗，这可有效维持电子架签10持续稳定的低功耗状态。
在发起方和响应方进行标识信息的传递过程中，本实施例并不限定标识信息的信息 格式，例如，标识信息可整体携带在一个数据包中进行传递，当然，标识信息还可采用其它的信息格式进行传递。在一种实现方式中，发起方和响应方均可将自身的标识信息拆分为N个数据段，N为正整数；按照N个数据段的排列顺序，确定N个数据段各自对应的序列号；根据N个数据段及其各自对应的序列号，分别进行数据编码，以生成N个数据包；双方可交换各自生成的N个数据包。
基于双方各自生成的N个数据包，发起方可将其首个数据包携带在信息交换请求中，而响应方可将其首个数据包携带在同意指示中。这样，双方可通过交换首个数据包，确认建立起标识信息交换通道，之后，双方可交换各自剩余的N-1个数据包。
例如，如图7所示，发起方的标识信息携带在6个数据包中，发起方可在输出间隙内循环输出其第1个数据包。而响应方进入侦听时隙时，可能接收到发起方的首个数据包，此时，响应方可将自身的首个数据包回复给发起方，至此，双方可成功建立起标识信息交换通道，并可交换各自剩余的5个数据包。
而对于各自剩余的N-1个数据包，双方可按图7所示的方式，按照数据包的顺序逐个进行数据包的交换。当然，双方也可按照其它方式进行剩余的N-1个数据包的交换，本实施例对此不作限定。例如，响应方可在全部接收完发起方剩余的N-1个数据包之后，再向发起方发送其自身剩余的N-1个数据包。
发起方和响应方均可根据各数据包中的序列号判断是否完成了全部数据包的接收工作。在完成数据包的接收工作后，双方将停止输出数据包。另外，双方之间交换标识信息过程中的数据包的结构以及编码协议等可参考前文中的描述，在此不再赘述。
据此，可实现两个电子架签10之间的双向通信。在双向通信模式下，双方均可获取到对方的标识信息并发送至服务器11。参考图6可知，每个电子架签10可能会接收到多个标识信息，例如，图6中的电子架签I可接收到4个标识信息，这种情况下，电子架签I可将接收到的所有标识信息均发送至服务器11。
值得说明的是，虽然图2和图6中分别示出了多个电子架签10在双向通信模式下的通信状态。但这并不代表多个电子架签10之间只能存在其中一种通信模式，多个电子架签10中任意两个视距范围存在重合的电子架签10之间可灵活设定通信模式。例如，图2中的A和B之间可采用单向通信模式，而图2中的A和H之间可采用双向通信模式。
图8为本申请另一实施例提供的一种位置关系校验方法的流程示意图。如图8所示，该方法可适用于电子架签，该方法包括：
100、基于视距通信接收视距范围内的第一目标电子架签发送的标识信息；
101、将自身的标识信息和第一目标电子架签的标识信息作为相对位置数据发送至服务器，以供服务器根据相对位置数据进行电子架签摆放位置关系校验。
本实施例提供的位置关系校验方法，可应用于各种需要进行位置关系校验的场景中，例如大型储物场所中的物品位置关系校验、电子架签位置关系校验等等，本实施例对此不作限定。
本实施例中，电子架签部署于物品货架中，与物品货架中的其它电子架签以及服务器可构成电子架签系统，本实施例中的电子架签可与电子架签系统中的其它电子架签进行视距传输，还可与服务器进行通信。电子架签在物品货架上的安装位置可对应物品货架上的一个陈列位置，电子架签在物品货架上的部署位置可灵活调整。在一些实际应用中，管理方可利用陈列管理软件的辅助手段，预先设计陈列图纸，从而通过陈列图纸表征出电子架签系统中各电子架签在物品货架上的部署结构，工作人员可按照陈列图纸进行电子架签的部署。
为了实现视距传输，电子架签中可安装视距通信装置，电子架签可利用视距通信装置与其视距范围内的电子架签进行视距通信。本实施例中，电子货架可基于视距通信接收视距范围内的第一目标电子架签发送的标识信息，并将自身的标识信息和第一目标电子架签的标识信息作为相对位置数据发送至服务器。
电子架签在向服务器发送相对位置数据时，可对相对位置数据进行加密和签名，而服务器可直接对相对位置数据进行解析、处理、存储和响应等等操作，从而保证了电子架签与服务器之间的所有中间转发设备无法进行窃听、伪造和篡改，安全性高，并发性能好，这为服务器校验位置关系奠定了数据安全基础。
据此，服务器可接收到大量的相对位置数据，通过这些相对位置数据，可确定出两两电子架签之间的相对位置，进而可确定出多个电子架签之间的实际摆放位置关系，并对多个电子架签之间的实际摆放位置关系进行校验。在一些实际应用中，服务器可将陈列图纸中包含的多个电子架签在物品货架上的部署结构与其确定出的实际摆放位置关系进行比对，从中定位出差异点位，从而筛选出摆放不符合陈列图纸的电子架签。
本实施例中，电子架签可基于视距通信接收其视距范围内的其它电子架签发送的标识信息，且可将自身的标识信息和接收到的标识信息发送至服务器，从而服务器可获得能够反映电子架签与其视距范围内的其它电子架签之间位置关系的相对位置数据。服务器可根据相对位置数据确定出电子架签与其它电子货架之间的实际摆放位置关系，基于此，可判断电子架签的实际摆放位置是否符合陈列图纸。因此，本申请实施例中，可基 于视距通信实现电子架签之间的相互定位，从而准确地确定出电子架签之间的实际摆放位置关系，进而可实现对物品货架的摆放情况的智能校验和稽查，可有效提高校验效率和准确度。
在上述或下述实施例中，电子架签还可监听预设的触发事件，并在触发事件发生时，基于视距通信将自身的标识信息发送给视距范围内的第二目标电子架签。
其中，触发事件可以是电子架签中的预设定位周期到达，也可以是接收到服务器下发定位指令等等，本实施例对此不作限定。电子架签可定时自动启动标识信息的发送操作，也可按照服务器的相关指令启动标识信息的发送操作。
对电子架签来说，其可能在多个方向上支持视距通信功能，为方便描述，将电子架签上支持视距通信功能的方向描述为数据传输方向，例如，当电子架签的上、下、左、右四个侧面上均配置有视距通信装置时，则电子架签可在其上、下、左、右四个数据传输方向上支持视距通信功能。其中，电子架签在其不同数据传输方向上所配置的视距通信装置可不完全相同，相应地，电子架签在不同数据传输方向上可支持的视距通信功能也可不完全相同。
例如，电子架签的上和下两个侧面上均安装有视距发送单元和视距接收单元，则电子架签在上和下两个数据传输方向上，均可支持双向通信模式。
又例如，电子架签的左侧面上仅安装有视距发送单元，则电子架签在左向的数据传输方向上，则仅可支持单向通信模式。
再例如，电子架签10的右侧面上仅安装有视距接收单元，则电子架签10在右向的数据传输方向上，则仅可支持单向通信模式。
据此，当电子架签在某一数据传输方向上的通信模式为单向通信模式时，电子架签作为该数据传输的其中一端，与该数据传输另一端电子架签之间进行标识信息的传递。为方便描述，将该数据传输两端的电子架签分别称为发送方和接收方，其中，本实施例中的电子架签可以作为发送方，也可以作为接收方。以下将对发送方和接收方的通信过程进行详细说明。
在单向通信模式下，发送方可将标识信息发送至接收方；接收方则可接收发送方发送的标识信息，而无需将自身的标识信息回传给发送方。据此，当电子架签作为接收方时，当电子架签处于单向通信模式时，可在侦听时隙内启动视距接收功能，以接收发送方发送的标识信息；当电子架签作为发送方时，可在输出时隙内循环输出自身的标识信息，以便接收方接收到该标识信息，其中，输出时隙的起点为触发事件发生时，输出时 隙大于接收方的休眠时隙。
另外，当电子架签作为发送方时，其输出时隙大于接收方的休眠时隙，而且，其输出时隙不再受其本身的侦听时隙和休眠时隙的限制。其中，休眠时隙是指电子架签处于深度休眠状态的时期。本实施例中，为了降低电子架签的功耗，可在电子架签中设定定时器，电子架签可在定时器的定时唤醒之下，定时醒来，进入侦听时隙，在侦听时隙中，电子架签可接收数据；而在侦听时隙之外的时期即为休眠时隙，在休眠时隙中，电子架签的电流可达到4uA，比侦听时隙中的电流5mA低3个数量级，因此，电子架签处于休眠时隙时可有效降低功耗。而且，本实施例中，在满足工作需求的情况下，还可将侦听时隙的长度设定的足够短，例如，侦听时隙的长度可比休眠时隙的长度短2～3个数量级，这可进一步降低电子架签的整体功耗。
基于此，电子架签作为发送方时的输出时隙大于接收方的休眠时隙，可保证接收方可在发送方的输出时隙内进入侦听时隙，从而接收方可成功接收到发送方发送的标识信息。
值得说明的是，当电子架签作为接收方在侦听到发送方正在向其发送标识信息时，电子架签的工作状态可不再受到侦听时隙的控制，也即是，无论侦听时隙是否足够用于完成接收发送方的标识信息的工作，电子架签可持续保持在工作状态，直至完成发送方的标识信息的接收工作。
据此，本实施例中，可将标识信息的接收过程压缩在电子架签正常的活动周期内，标识信息的接收过程不会增加电子架签在侦听时隙内的功耗，这可有效维持电子架签持续稳定的低功耗状态。
在电子架签进行标识信息的传递过程中，本实施例并不限定标识信息的信息格式，例如，标识信息可整体携带在一个数据包中进行传递，当然，标识信息还可采用其它的信息格式进行传递。在一种实现方式中，当电子架签作为发送方时，可将自身的标识信息拆分为N个数据段，N为正整数；按照N个数据段的排列顺序，确定N个数据段各自对应的序列号；根据N个数据段及其各自对应的序列号，分别进行数据编码，以获得N个数据包；将N个数据包发送至接收方。同理，当电子架签作为接收方时，可接收发送方发送的N个数据包。
例如，电子架签作为发送方时，可将标识信息拆分为6个数据段，以生成6个数据包，电子架签可在输出间隙内按序循环输出这6个数据包。而接收方进入侦听时隙时，可能首先接收到的是6个数据包中的非首个数据包，此时，接收方可继续接收发送方后 续的数据包，也即是第1-5个数据包，直至完成6个数据包的接收工作。当电子架签作为接收方时，可根据各数据包中的序列号判断是否完成了全部数据包的接收工作，在完成数据包的接收工作后，电子架签可通知发送方接收工作已完成，发送方将停止输出数据包；当然，电子架签也可不通知发送方，发送方将在输出时隙结束后停止输出数据包。
在一些实际应用中，每个数据包中可包含起始位、序列号和数据段。起始位之后是序列号，序列号用于表征当前数据段在标识信息中的位置，序列号之后为数据段。数据包中还可包含奇偶校验位用于校验数据包的完整性。数据包中还可在数据段之后用一空白间隔表征数据包的结束，以实现分段。
例如，电子架签的标识信息为0X112233445566，电子架签作为发送方时，可将标识信息拆分为6个数据段“11”、“22”、“33”、“44”、“55”和“66”，按照6个数据段的排列顺序，可确定出各数据段对应的序列号，据此，第一个数据包中至少包含的字节有：11000000010001，第二个数据包中至少包含的字节有：11000100100010，同理，其它的数据包不再赘述。
电子架签作为发送方时，可与接收方之间按照约定的通信编码协议进行通信。电子架签可采用PWM脉冲输出，并按照曼彻斯特编码方式进行数据包的发送，也即是以电平的变化表征数据包中的逻辑1和逻辑0，以形成数据流，从而实现数据包的视距传输。当然，本实施例并不限于此。
据此，可实现电子架签与其视距范围内的电子架签之间的单向通信。在单向通信模式下，电子架签作为接收方时，在接收到作为发送方的电子架签发送的标识信息后，可将其自身的标识信息及接收到的标识信息发送至服务器。电子架签作为接收方时可能会接收到多个标识信息，这种情况下，电子架签可将接收到的所有标识信息均发送至服务器。
当电子架签在某一数据传输方向上的通信模式为双向通信模式时，电子架签在该数据传输方向上与其视距范围内的电子架签之间进行标识信息的交换。为方便描述，将双向通信的两端电子架签分别称为发送方和接收方，其中，本实施例中的电子架签可以作为双向通信的发起方，也即是启动双向通信的一方，也可以作为响应方。以下将对发起方和响应方之间的双向通信过程进行详细说明。
在双向通信模式下，两个电子架签之间可相互传递标识信息。当电子架签作为响应方时，电子架签可在侦听时隙内启动视距接收功能，以接收视距范围内的发起方发送的信息交互请求；并向发起方发送同意指示以建立与发起方之间的标识信息交换通道；利 用标识信息交换通道与发起方交换标识信息，以获得发起方的标识信息。当电子架签作为发起方时，可在输出时隙内循环输出信息交互请求，输出时隙的起点为触发事件发生时，输出时隙大于视距范围内的响应方的休眠时隙；并在接收到响应方发送的同意指示时，与响应方交换标识信息。
其中，发起方的输出时隙的起点为触发事件发生时。触发事件可以是发起方中的预设定位周期到达，也可以是接收到服务器下发定位指令等等，本实施例对此不作限定，发起方可定时自动启动信息交互请求的发送操作，也可按照服务器的相关指令启动信息交互请求的发送操作。
另外，电子架签作为发起方时，其输出时隙大于响应方的休眠时隙，而且，电子架签的输出时隙不再受其本身的侦听时隙和休眠时隙的限制。关于电子架签的侦听时隙和休眠时隙的相关描述可参考前文，在此不再赘述。
基于此，电子架签作为发起方时，可在输出时隙内循环发送信息交互请求，由于响应方的休眠时隙小于电子架签的输出时隙，因此，可保证响应方至少可在电子架签的输出时隙之内进入侦听时隙，从而响应方可成功接收到电子架签发送的信息交互请求。电子架签作为响应方时，可在接收到发起方的信息交互请求时，可向发起方回传同意指示，从而建立起双方之间的标识信息交换通道，双方可利用标识信息交换通道进行标识信息的交换。
值得说明的是，当标识信息交换通道后，电子架签的工作状态可不再受到输出时隙和/或侦听时隙的限制。也即是，无论电子架签的输出时隙和/或侦听时隙是否足够用于完成标识信息的传递，电子架签都可持续保持在工作状态，直至完成标识信息的传递。
据此，本实施例中，可将标识信息的接收过程压缩在电子架签正常的活动周期内，标识信息的接收过程不会增加电子架签在侦听时隙内的功耗，这可有效维持电子架签持续稳定的低功耗状态。
在电子架签进行标识信息的传递过程中，本实施例并不限定标识信息的信息格式，例如，标识信息可整体携带在一个数据包中进行传递，当然，标识信息还可采用其它的信息格式进行传递。在一种实现方式中，电子架签可将自身的标识信息拆分为N个数据段，N为正整数；按照N个数据段的排列顺序，确定N个数据段各自对应的序列号；根据N个数据段及其各自对应的序列号，分别进行数据编码，以生成N个数据包；电子架签可在双向通信模式下，与视距范围内的电子架签交换各自生成的N个数据包。
当电子架签作为发起方时，电子架签可将其首个数据包携带在信息交换请求中，而 电子架签作为响应方时，电子架签可将其首个数据包携带在同意指示中。这样，在双向通信模式下，可通过交换首个数据包，确认建立起标识信息交换通道，之后，电子架签可与其视距范围内的电子架签交换各自剩余的N-1个数据包。
例如，电子架签可将自身的标识信息拆分为6个数据段，以生成6个数据包。电子架签作为发起方时，可在输出间隙内循环输出其第1个数据包，而响应方进入侦听时隙时，可能接收到发起方的首个数据包，此时，响应方可将自身的首个数据包回复给电子架签，至此，双方可成功建立起标识信息交换通道，并可交换各自剩余的5个数据包。
而对于各自剩余的N-1个数据包，双方可按照数据包的顺序逐个进行数据包的交换。当然，双方也可按照其它方式进行剩余的N-1个数据包的交换，本实施例对此不作限定。例如，响应方可在全部接收完发起方剩余的N-1个数据包之后，再向发起方发送其自身剩余的N-1个数据包。
电子架签可根据各数据包中的序列号判断是否完成了全部数据包的交换工作。在完成数据包的交换工作后，电子架签将停止传递数据包。另外，电子架签在双向通信模式下的数据包的结构以及编码协议等可参考前文中的描述，在此不再赘述。
据此，可实现电子架签与其视距范围内的电子架签之间的双向通信。在双向通信模式下，电子架签可获取到对方的标识信息并发送至服务器。每个电子架签可能会接收到多个标识信息，这种情况下，电子架签可将接收到的所有标识信息均发送至服务器。
值得说明的是，虽然上文中分别阐述了电子架签的两种通信模式。但这并不代表电子架签只能采用其中的一种通信模式，电子架签的不同数据传输方向上可采用不同的通信模式，例如，图2中的电子架签A与其右侧的电子架签B之间可配置单向通信模式，而电子架签A与其下侧电子架签H之间则可配置双向通信模式。
另外，上述位置关系校验方法的各个实施例中的各技术细节，可参考前文中电子架签系统中的相关描述，在此不再赘述，但这不应造成对本申请保护范围的损失。
相应地，本申请实施例还提供一种存储有计算机程序的计算机可读存储介质，计算机程序被执行时能够实现上述方法实施例中可由电子架签执行的各步骤。
图9为本申请又一实施例提供的另一种位置关系校验方法的流程示意图。如图9所示，该方法适用于电子架签，该方法包括：
200、监听设定的触发事件；
201、在触发事件发生时，基于视距通信将自身的标识信息发送给视距范围内的目标电子架签，以便目标电子架签将其自身的标识信息和接收到的标识信息作为相对位置数 据发送至服务器，以供服务器根据相对位置数据进行电子架签摆放位置关系校验。
本实施例提供的位置关系校验方法，可应用于各种需要进行位置关系校验的场景中，例如大型储物场所中的物品位置关系校验、电子架签位置关系校验等等，本实施例对此不作限定。
本实施例中，电子架签部署于物品货架中，与物品货架中的其它电子架签以及服务器可构成电子架签系统，电子架签可以其它电子架签进行视距传输，还可与服务器进行通信。电子架签可对应物品货架上的一个陈列位置，电子架签在物品货架上的部署位置可灵活调整。在一些实际应用中，管理方可利用陈列管理软件的辅助手段，预先设计陈列图纸，从而通过陈列图纸表征出各电子架签在物品货架上的部署结构，工作人员可按照陈列图纸进行电子架签的部署。
为了实现视距传输，电子架签中可安装视距通信装置，电子架签可利用视距通信装置与其视距范围内的电子架签进行视距通信。本实施例中，电子货架可基于视距通信将自身的标识信息发送给视距范围内的目标电子架签，以便目标电子架签将其自身的标识信息和接收到的标识信息作为相对位置数据发送至服务器，以供服务器根据相对位置数据进行电子架签摆放位置关系校验。
电子架签在与其视距范围内的目标电子架签进行标识信息的传递过程中，可作为发送方且采用单向通信模式，具体过程可参考前述实施例中有关单向通信模式的相关描述，在此不再赘述。
另外，上述位置关系校验方法的各个实施例中的各技术细节，可参考前文中电子架签系统中的相关描述，在此不再赘述，但这不应造成对本申请保护范围的损失。
相应地，本申请实施例还提供一种存储有计算机程序的计算机可读存储介质，计算机程序被执行时能够实现上述方法实施例中可由电子架签执行的各步骤。
图10为本申请又一实施例提供的又一种位置关系校验方法的流程示意图。适用于电子架签系统中的服务器，如图10所示，该方法包括：
300、接收多个电子架签发送的相对位置数据，相对位置数据包含电子架签自身的标识信息和其视距范围内的电子架签的标识信息；
301、根据相对位置数据，确定多个电子架签之间的实际摆放位置关系，并对多个电子架签之间的实际摆放位置关系进行校验。
本实施例中，多个电子架签可与服务器进行通信，其中，电子架签与服务器之间可以是无线或有线网络连接。例如，电子架签与服务器之间可通过无线访问接入点(AP， Access Point)实现相对位置数据的传输。当然，电子架签与服务器之间还可采用其它网络连接方式实现相对位置数据的传输，例如，移动网络等。其中，移动网络的网络制式可以为2G(GSM)、2.5G(GPRS)、3G(WCDMA、TD-SCDMA、CDMA2000、UTMS)、4G(LTE)、4G+(LTE+)、WiMax、5G，Bluetooth low energy等中的任意一种。
多个电子架签部署于物品货架中，每个电子货架标签可对应物品货架上的一个陈列位置，多个电子架签在物品货架上的部署结构可灵活调整。在一些实际应用中，管理方可利用陈列管理软件的辅助手段，预先设计陈列图纸，从而通过陈列图纸表征出各电子架签在物品货架上的部署结构，工作人员可按照陈列图纸进行电子架签的部署。
多个电子货架之间可在各自的视距范围内传递标识信息，据此，对于多个电子架签中的一部分电子架签来说，可获取到其视距范围内其它电子架签的标识信息，这类电子架签可将自身的标识信息和接收到的标识信息作为相对位置数据发送至服务器。其中，有关电子架签之间的标识信息的传递过程可参考前述实施例中的相关描述，在此不再赘述。
本实施例中，电子架签在向服务器发送相对位置数据时，可对相对位置数据进行加密和签名，而服务器可直接对相对位置数据进行解析、处理、存储和响应等等操作，从而保证了电子架签与服务器之间的所有中间转发设备无法进行窃听、伪造和篡改，安全性高，并发性能好，这为服务器校验位置关系奠定了数据安全基础。
据此，服务器可接收到大量的相对位置数据，通过这些相对位置数据，可确定出两两电子架签之间的相对位置，进而可确定出多个电子架签之间的实际摆放位置关系，并对多个电子架签之间的实际摆放位置关系进行校验。在一些实际应用中，服务器可将陈列图纸中包含的多个电子架签之间的摆放位置与其确定出的实际摆放位置关系进行比对，从中定位出差异点位，从而筛选出摆放不符合陈列图纸的电子架签。
另外，服务器可获取各电子架签10各自关联的至少一个物品的物品信息，并可基于确定出的多个电子架签之间的实际摆放位置关系及各电子架签各自关联的至少一个物品的物品信息，生成物品货架中各物品的实际陈列关系，并对物品货架中各物品的实际陈列关系进行校验。在一些实际应用中，前述的陈列图纸中还可包含物品货架上各物品之间的摆放关系，服务器可将陈列图纸中包含的物品货架上各物品之间的摆放关系与其确定出的各物品的实际陈列关系进行比对，从中定位出差异点位，从而筛选出摆放不符合陈列图纸的物品。
在物品货架上，各物品的陈列方式多种多样，从陈列位置的维度来说，每个陈列位 置上可包含至少一个物品，当单个陈列位置上包含多个物品时，这些物品可以属于同一物品类，例如，一个陈列位置上可摆放多瓶A牌牛奶；这些物品也可属于不同物品类，例如，一个陈列位置上可摆放可成对出售的碗和筷子。本实施例对此均不作限定。
据此，在一些实际应用中，电子架签系统中还可包含手持终端，手持终端用于采集物品货架中任意物品的物品信息，包括编码信息、所属类别等等；手持终端还可用于采集各物品所在陈列位置所对应的电子架签10的标识信息，并将物品信息和电子架签的标识信息关联发送至服务器。服务器可据此获取到各电子架签各自关联的至少一个物品的物品信息，以便在对物品货架进行位置关系校验时，根据多个电子架签之间的实际摆放位置关系，准确地确定出各物品的实际陈列关系。
本实施例中，部署于物品货架上的多个电子架签之间，可基于视距通信进行标识信息的传递，这个过程将产生大量的相对位置数据。这些相对位置数据将被发送到服务器，服务器可根据这些相对位置数据确定出多个电子架签之间的实际摆放位置关系，基于此，可判断电子架签之间的实际摆放位置关系是否符合陈列图纸。因此，本申请实施例中，可基于视距通信实现电子架签之间的相互定位，从而准确地确定出电子架签之间的实际摆放位置关系，进而可实现对物品货架的摆放情况的智能校验和稽查，可有效提高校验效率和准确度。
另外，上述位置关系校验方法的各个实施例中的各技术细节，可参考前文中电子架签系统中的相关描述，在此不再赘述，但这不应造成对本申请保护范围的损失。
相应地，本申请实施例还提供一种存储有计算机程序的计算机可读存储介质，计算机程序被执行时能够实现上述方法实施例中可由服务器执行的各步骤。
需要说明的是，在上述相关方法实施例及附图中的描述的一些流程中，包含了按照特定顺序出现的多个操作，但是应该清楚了解，这些操作可以不按照其在本文中出现的顺序来执行或并行执行，操作的序号如100、101等，仅仅是用于区分开各个不同的操作，序号本身不代表任何的执行顺序。另外，这些流程可以包括更多或更少的操作，并且这些操作可以按顺序执行或并行执行。需要说明的是，本文中的“第一”、“第二”等描述，是用于区分不同的消息、设备、模块等，不代表先后顺序，也不限定“第一”和“第二”是不同的类型。
