背景技术
电子价签(ESL，Electronic Shelf Label)是一种放置于货架上，以替代纸质价签并用于显示产品的价目、名称、产地等商品信息的电子显示装置。电子价签可以接收服务端下发的价签信息，并将价签信息中的商品信息显示在其显示屏幕上，减少纸质价签更换商品信息的成本，提高更新效率。
商品陈列巡检在零售行业里属于高频刚需，目前商品陈列巡检需要巡检人员确定每个电子价签与对应商品的摆放位置，将所有电子价签的摆放位置与陈列效果图进行比较，从而查找出摆放错误的商品对象，这种巡检方式会消耗大量的人力成本以及时间成本；另一种巡检方式是巡检人员通过图像识别来确认电子价签的显示信息，进而判断电子价签的位置及其对应的商品是否摆放正确，这种巡检方式对图像识别系统的要求很高，导致实现成本过高。因此，如何以低成本的方式实现自动确定电子价签的摆放位置是目前亟需解决的问题。

具体实施方式
在下面的描述中阐述了很多具体细节以便于充分理解本说明书。但是本说明书能够以很多不同于在此描述的其它方式来实施，本领域技术人员可以在不违背本说明书内涵的情况下做类似推广，因此本说明书不受下面公开的具体实施的限制。
在本说明书一个或多个实施例中使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本说明书一个或多个实施例。在本说明书一个或多个实施例和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示 其他含义。还应当理解，本说明书一个或多个实施例中使用的术语“和/或”是指包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本说明书一个或多个实施例中可能采用术语第一、第二等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本说明书一个或多个实施例范围的情况下，第一也可以被称为第二，类似地，第二也可以被称为第一。取决于语境，如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
首先，对本说明书一个或多个实施例涉及的名词术语进行解释。
电子价签：一种带有信息收发功能的电子显示装置，主要应用于超市、便利店、药房等显示价格信息的电子类标签。放置在货架上，可替代传统纸质价格标签的电子显示装置，每一个电子货架标签通过有线或者无线网络与商场计算机数据库相连，并将最新的商品信息通过电子价签上的屏显示出来。
光电对管：又称光电开关，内部结构为一个发光二极管和一个光敏三极管。由振荡回路产生的调制脉冲经发射电路后，由发光管辐射出光脉冲。当被测物体进入受光器作用范围时，被反射回来的光脉冲进入光敏三极管。并在接收电路中将光脉冲解调为电脉冲信号，再经放大器放大和同步选通整形，然后用数字积分光电开关或RC积分方式排除干扰，最后经延时(或不延时)触发驱动器输出光电开关控制信号。
电子价签所在的空间位置，可以用于检查当前货物的摆放与预期是否一致，检查电子价签与货物是否相符，通过准确的获取电子价签在货架上的位置，可以保证商品陈列的准确性，降低价签与商品不对应导致的投诉率与合规风险。准确的电子价签空间位置，为拣货亮灯系统的可用性提供基础。实时准确空间位置的电子价签，添加信标发射功能后，保证室内导航功能所需定位锚点信息的实时性与准确性。室内定位能力是商超运营数字化战略中重要的基础设施。商超零售门店中广泛布局导轨供电的ESL(电子价签)，通过有效设计策略和方案，在导轨供电ESL区域共享ESL硬件作为定位锚点基础设施，实现满足营运数字化需求的空间定位能力，将可发挥ESL基础设施的更多潜能，并大大缩减定位能力建设的设备投入及维保投入。结合新零售场景，开发出来除价格信息展示功能以外的更多需求，赋予电子价签更高ROI(投资回报率)，为电子价签更大范围的普及应用提供基础。
电子价签(ESL)作为商超零售行业数字化的基础设施，已经在行业大批量复制，期望通过简单的低成本硬件和软件升级，增加ESL的自身精细定位相关基础能力，实现零售场景ESL硬件的更多数字化价值挖掘。蓝牙技术的ESL增加标准Beacon定位信号源功能，受限于ESL位置调整带来的位置不确定性，难以得到推广。排面巡检在零售行业里面属于高频刚需，自动化排面巡检期望可以检出ESL位置错乱，通过图像识别来确认ESL显示信息，进而确定ESL身份的方法，对图像获取系统的性能指标提出较高要求，阻碍该需求的自动化方案低成本实现。
现有技术中通过独立部署的定位Beacon信标系统来实现电子价签的自定位功能，物流仓储行业一般采用独立部署的定位Beacon信标系统。独立部署的定位Beacon信标系统一般要求5米网格内部署至少1个Beacon信标。商超场景下，独立部署Beacon信标系统缺点包括：单独系统，独立造价，硬件成本较高、一次性使用，设备使用寿命有限，后期维保支出较高、安装位置受限现场条件，需要专业部署人员与工具系统、受限部署密度，一般采用蓝牙指纹技术来计算位置，需要现场采集指纹数据。
现有技术中还通过RFID定位系统来实现电子价签的自定位功能，使用RFID锚点定位的系统，需要在电子价签导轨上面均匀密布RFID贴片，并且在电子价签上面配置RFID读卡芯片，通过RFID读卡芯片读取导轨RFID贴片ID信息，再在事先绘制好的导轨RFID位置图中寻找对应ID编号，确定其所在位置。商超场景下，RFID锚点定位系统缺点包括：系统造价较高、数据库维护线上线下一致的导轨RFID位置图需要一定成本、RFID通信占用无线信道，影响现场无线设备通信稳定性与可靠性。
现有技术中还通过赋予特定位置ESL定位Beacon信标功能的定位系统来实现电子价签的自定位功能，通过选取固定在特征位置点的ESL，使用大容量电池作为标准Beacon广播信标，实现室内定位系统。该系统缺点包括：ESL位置可能会随SPT宽度及位置调整而更换位置，影响定位功能、现场环境变化导致的信号遮挡将对定位精度带来不确定性影响、赋予定位功能的ESL作为单独ESL种类，需要有独立的管理系统来管理。
基于此在本说明书中，提供了一种位置识别方法，本方法通过供电导轨设计和ESL软硬件设计，实现ESL导轨范围内的精准自定位能力，赋予ESL精准定位锚节点能力。本说明书同时涉及一种位置识别系统，一种计算设备，一种计算机可读存储介质以及一种计算机程序，在下面的实施例中逐一进行详细说明。
图1示出了根据本说明书一个实施例提供的一种位置识别方法的流程图，包括步骤102，其中，所述位置识别方法应用于位置识别系统，所述系统包括设置有定位标记信息的供电导轨、以及安装在所述供电导轨上的电子价签，且所述电子价签中设置有光电对管。
步骤102：所述电子价签，基于所述光电对管读取对应的所述供电导轨上的定位标记信息，并根据所述定位标记信息，确定在所述供电导轨的目标位置。
其中，供电导轨可以理解为安装在货架上为电子价签供电的装置，一个供电导轨上可以安装多个电子价签，获取到每个电子价签的准确位置，从而可以知道每个电子价签与对应的商品是否对应一致，保证商品与电子价签两者的摆放位置正确。定位标记信息可以理解为用于确定电子价签在供电导轨上位置的信息。
在实际应用中，以商超场景为例，商超中包括多个供电导轨，每个供电导轨上安装有多个电子价签，每个电子价签对应一种商品。为了保证电子价签与商品之间对应的准确性，因此需要确保电子价签安装在预设的位置上，因此该方法中电子价签通过光电对管读取对 应的定位标记信息，根据定位标记信息确定自身在供电导轨上的位置。需要注意的是，相较于其他获取定位标记信息的方式，本方法采用光电对管读取定位标记信息，由于光电对管的价格便宜，安装结构简单，使得本说明书提供的位置识别方法实现成本低，同时也能达到准确的识别效果。在具体实施时，还可以为电子价签配备一个后台管理系统，后台管理系统可以根据工作人员提前设置的商品陈列表实时监控每个电子价签是否在正确的位置，从而确保所有供电导轨上的电子价签的位置都正确无误。
具体地，所述电子价签，发送所述目标位置至控制器；
所述控制器，根据商品陈列表和所述目标位置确定所述电子价签的安装信息，其中，所述商品陈列表中包括每个商品对应的商品摆放信息以及商品标签信息，所述商品摆放信息用于确定商品与摆放位置的对应关系，所述商品标签信息用于确定商品与电子价签的对应关系。
其中，控制器可以理解为后台管理系统的处理器，控制器根据工作人员输入的商品陈列表可以判断电子价签是否在正确位置，商品陈列表中记录了商品、位置、电子价签标识之间的对应关系，举例说明，A商品对应的位置为供电导轨的第1位，该位置对应的电子价签标识应该为电子价签1，则当电子价签1发送自身的目标位置至控制器之后，控制器可以依据商品陈列表进行判断，判断电子价签1发送的目标位置与商品陈列表中的关系对应，则确定电子价签1安装在正确位置。
其中，电子价签安装在供电导轨上之后，接受供电导轨的供电。电子价签会立即基于光电对管读取供电导轨上的定位标记信息，从而根据定位标记信息判断出自身在供电导轨上的目标位置，目标位置可以理解为电子价签在供电导轨上的相对位置，目标位置可以是电子价签在供电导轨上的第几位，也可以是电子价签的排列顺序，例如，供电导轨上安装有10个电子价签，每个电子价签对应有一个定位标记信息，根据每个电子价签对应的定位标记信息可以知道每个电子价签在供电导轨上的具体位置，也可以确定这10个电子价签的排列顺序。即同供电导轨上的电子价签可以依据对应的定位标记信息进行相对位置排序。
在实际应用中，供电导轨上可能会安装多个电子价签，但每个电子价签不确定对于自身所在供电导轨的位置，因此，电子价签可以读取自身所在位置对于的定位标记信息，从而确定在供电导轨的具体位置。
在本说明书一实施例中，供电导轨上设置有定位标记信息，分别是00和01。将电子价签A安装在其中一个定位标记信息对应的位置之后，电子价签基于光电对管读取所在位置的定位标记信息为00，则电子价签可以确定自身在供电导轨的第1位，即在定位标记信息为00的位置。
本说明书实施例提供的位置识别方法，通过在供电导轨上配置定位标记信息，使电子价签安装在供电导轨上之后，可以基于光电对管读取电子价签所在位置对应的定位标记信 息，从而判断出自身在供电导轨上的目标位置，以低成本的方式实现电子价签的自定位功能。
具体地，所述基于所述光电对管读取对应的所述供电导轨上的定位标记信息，包括：
所述电子价签，确定安装在所述供电导轨的安装位置，基于所述光电对管读取与所述安装位置对应的定位标记信息。
其中，安装位置可以理解为在供电导轨上安装电子价签的位置，在实际应用中，供电导轨可以设置为任意位置都可以安装，则在电子价签安装至供电导轨上之后，才能确定出该电子价签对应的安装位置。通过读取该安装位置对应的定位标记信息，从而确定电子价签在供电导轨上的目标位置。
在本说明书一实施例中，供电导轨上任意地方可以安装电子价签，在电子价签A安装与供电导轨上之后，确定电子价签A的安装位置，电子价签A基于光电对管读取该安装位置对应的定位标记信息，并确定自身所在供电导轨上的目标位置。
在另一个实施例中，安装位置也可以是供电导轨上提前设置好的，具体地，所述基于所述光电对管读取对应的所述供电导轨上的定位标记信息，包括：
所述电子价签，安装在所述供电导轨的安装位置，基于所述光电对管读取所述安装位置的定位标记信息。
在实际应用中，也可以提前设置供电导轨上可以安装电子价签位置，当电子价签安装在某个安装位置之后，电子价签可以通过光电对管读取该安装位置的定位标记信息。
在本说明书另一实施例中，供电导轨上设置有3个安装位置，分别是安装位置1、安装位置2、安装位置3，在电子价签A安装在供电导轨上的安装位置1之后，电子价签A基于光电对管读取安装位置1对应的定位标记信息，根据该定位标记信息确定自身所在供电导轨上的具体位置。
在实际应用中，定位标记信息可以是位置编码，则电子价签可以根据位置编码确定在供电导轨的目标位置。具体地，所述定位标记信息包括位置编码；
所述根据所述定位标记信息，确定在所述供电导轨的目标位置，包括：
所述电子价签，根据所述位置编码，确定在所述供电导轨的目标位置。
具体实施时，供电导轨配置有位置编码，本说明书一实施例中采用二进制条形编码作为位置编码，如图2所示，图2示出了根据本说明书一个实施例提供的一种供电导轨位置编码示意图，其中，供电导轨上配置有位置编码，供电导轨的位置编码采用二进制编码，黑色条代表二进制0，白色条代表二进制1，当电子价签安装在供电导轨上时，电子价签基于光电对管读取到所在位置的二进制编码，从而确定自身在供电导轨上的所在位置。位置编码配置在供电导轨上时，可以采用递增编码方法，例如图2中，从左侧至右侧为0000、0001……1110，也可以采用递减编码方法，从左侧至右侧为1111、1110……0000，需要注 意的是，供电导轨上部两条编码信息条可以为二进制编码的高位，也可以为二进制编码的低位，导轨下部两条编码信息条可以为二进制编码的低位，也可以为二进制编码的高位，供电导轨上的位置编码的编码顺序以及编码高低位可以根据实际应用场景确定，本说明书在此不作具体限制。
在本说明书一实施例中，供电导轨上配置有位置编码000至111，为了保证每个位置编码都可以对应一个位置编码，该供电导轨可以安装8个电子价签，当电子价签A安装在该供电导轨上之后，通过光电对管读取所在位置的位置编码，为010，则电子价签可以确定自身在供电导轨上的位置是从左至右数第3个位置，后续可以通过后台管理系统进一步确定该电子价签所在的位置是否与预期的位置一致，从而确保电子价签的位置安装正确，使得电子价签与所在位置的商品具有对应关系。
具体地，所述位置编码包括二进制位置编码，其中，所述二进制位置编码的位数与所述光电对管的数量相同，所述二进制位置编码通过黑白贴条确定，且所述光电对管对准所述二进制位置编码的中央区域；
所述电子价签，根据所述位置编码，确定在所述供电导轨的目标位置，包括：
所述电子价签，根据所述二进制位置编码，确定在所述供电导轨的目标位置。
实际应用中，所述电子价签，会将所述二进制位置编码转换成目标位置编码，根据所述目标位置编码确定在所述供电导轨的目标位置。
其中，位置编码可以理解为供电导轨上配置的二进制位置编码，当电子价签安装在供电导轨上之后，则可以对所在位置的二进制位置编码进行读取，将读取获得的二进制位置编码转换成目标位置编码之后，确定电子价签的目标位置。例如，读取的二进制位置编码为0001，目标位置编码为十进制位置编码，也可以设置为其他进制位置编码，如八进制位置编码、十六进制位置编码等，则转换成目标位置编码之后为1，由于供电导轨上位置编码的顺序为从左至右，左侧第1位为0000，则确定该电子价签对应的目标位置为左侧第2位。
需要注意的是，供电导轨上二进制位置编码的位数，与电子价签上配置的光电对管的数量相同，每个光电对管只能读取位置编码中的一位，并且根据光电对管的读取方式，采用黑白贴条设置二进制位置编码，光电对管感应到黑色贴条则表示为二进制0，光电对管感应到白色贴条则表示为二进制1。例如，二进制位置编码0000有四位，则电子价签上应配置有4个光电对管，每个光电对管分别对准一路位置编码，参见图3，图3示出了本说明书一实施例提供的一种电子价签示意图，其中，电子价签背部安装有4路光电对管，通过光电对管识别供电导轨的位置编码，从而确定电子价签所在位置对应的位置编码，在图3中，电子价签通过4路光电对管感应到位置编码0010。具体实施时，电子价签背部，贴近供电导轨底面的区域，上下顺序均匀配置光电对管，配置的光电对管的数量可以根据供电导轨的位置编码确定，例如供电导轨的位置编码有5位，则电子价签相对应配置有5路 光电对管，本说明书中对位置编码的位数，以及光电对管的数量不作具体限制，可以根据实际情况确定。
具体实施时，在根据黑白贴条设置二进制位置编码时，可以在每一段二进制位置编码中留有空白区域，以此区分不同的安装位置，当电子价签安装在二进制位置编码区域时，能够获取到正常的二进制位置编码，当电子价签安装在空白区域时，获得到非正常的二进制位置编码，因此在电子价签根据目标位置编码确定目标位置时，需要进行安装位置是否为异常位置的判断。
所述电子价签，在所述二进制位置编码为待验证位置编码的情况下，获取所述电子价签的相邻电子价签对应的相邻位置编码；
所述电子价签，根据所述相邻电子价签对应的相邻位置编码判断是否在异常位置，若是，发送报警信息，若否，根据所述相邻电子价签对应的相邻位置编码确定目标位置。
其中，待验证位置编码可以理解为空白区域对应的位置编码，本说明书实施例中，由于空白区域中未设置黑白贴条，则待验证位置编码默认为0000。当电子价签获取的二进制位置编码为0000的情况下，则进行所在位置是否为异常位置的判断。
相邻电子价签对应的相邻位置编码可以理解为在电子价签两边的供电导轨对应的相邻位置编码，例如，电子价签1、电子价签2、电子价签3依次安装在供电导轨上，则电子价签2的相邻电子价签为电子价签1和电子价签3，根据相邻电子价签对应的相邻位置编码则可以判断出电子价签2的具体位置。举例说明，电子价签1对应的相邻位置编码为0010，电子价签对应的相邻位置编码为0011，则可以说明根据电子价签2的位置编码0000确定出的目标位置是异常位置，此时，电子价签2可以发送报警信息。需要说明的是，电子价签发送报警信息可以是直接发送异常报警信息至后台管理系统，提醒工作人员该电子价签安装位置错误；也可以是启用蜂鸣器等声音装置提醒安装工作人员重新安装，本说明书对电子价签的报警方式不作具体限制，根据实际情况确定。
相应的，本说明书另一实施例中，电子价签2只有一个相邻电子价签为电子价签3，而电子价签3对应的位置编码为0001，则当电子价签2的位置编码为0000时，说明电子价签安装在供电导轨的最左侧，则电子价签2的安装位置正确。
在实际应用中，由于供电导轨上配置有位置编码，为了保证每个电子价签都对应有所在安装位置的位置编码，例如，电子价签1安装在供电导轨上之后，识别出所在位置的位置编码为0000，电子价签2安装在供电导轨上之后，识别出所在位置的位置编码为0001，则可以根据供电导轨的长度信息和电子价签的宽度信息确定供电导轨上的定位标记信息。
具体地，所述系统还包括控制器，其中，
所述控制器，获取所述供电导轨的长度信息以及所述电子价签的宽度信息，根据所述长度信息和所述宽度信息，确定所述供电导轨上的定位标记信息。
其中，控制器可以理解为后台管理系统中的控制器，控制器可以用于确定供电导轨上 的定位标记信息的范围。根据供电导轨的长度信息和电子价签的宽度信息确定供电导轨的定位标记信息，实际上是先确定该供电导轨上可以安装多少个电子价签，根据安装的电子价签的数量确定定位标记信息的范围，并根据预设的起始定位标记信息确定出供电导轨上的定位标记信息。
具体地，根据所述长度信息和所述宽度信息，确定所述供电导轨上的定位标记信息，包括：
所述控制器，根据所述长度信息和所述宽度信息，确定所述供电导轨上所述电子价签的可安装位置，并为所述可安装位置配置对应的定位标记信息。
在实际应用中，为了确保每个电子价签都可以获取到不同的位置编码，因此需要保证每个位置编码上至多安装一个对应的电子价签，因此需要根据供电导轨的长度信息和电子价签的宽度信息去确定供电导轨所能安装电子价签的最大数量，即供电导轨上对于电子价签的可安装位置，根据可安装位置确定出供电导轨的位置编码范围，并根据预设的起始定位标记信息为每个可安装位置配置对应的定位标记信息，从而确定出供电导轨上的定位标记信息。
其中，位置编码范围可以理解为供电导轨上位置编码的数量范围，当供电导轨上位置编码为4路时，代表供电导轨的位置编码范围为0000-1111，总计布局了16组不同的位置编码。
在本说明书一实施例中，电子价签的宽度信息为7cm(厘米)，供电导轨最大可安装电子价签的长度信息为90cm，因此计算出供电导轨上的可安装位置为12个，则安装的电子价签数量不能大于12，为了保证这12个电子价签有不同的位置编码，因此供电导轨至少需要布局12组位置编码，因此确定出供电导轨可采用4路二进制编码，根据预设的起始定位标记信息0000，确定出供电导轨上的定位标记信息为0000至1111，满足精度需求，保证该供电导轨上最大数量安装电子价签时，也可以使得每个电子价签读取到不同的位置编码。
在本说明书另一种可行的实施例中，电子价签还可以基于位置分布信息确定自身在供电导轨上的目标位置。具体地，所述电子价签，获取供电导轨对应的位置分布信息，根据所述位置编码在所述位置分布信息中确定所述电子价签在所述供电导轨的目标位置。
其中，位置分布信息可以理解为工作人员提前设定的供电导轨以及电子价签的对应位置的信息，例如，预期将电子价签1、电子价签2安装在供电导轨A的最左侧和最右侧，或者将电子价签3、电子价签4安装在供电导轨B的最左侧和最右侧，则位置分布信息中则记录这些分布信息，在获取供电导轨A的位置分布信息之后，则可以知道在最左侧第1位应该安装的是电子价签1，在最右侧安装的是电子价签2，根据电子价签的定位标记信息，即位置编码，可以在位置分布信息中进行查找，查找到电子价签1对应的位置应该在最左侧，则可以确定实际电子价签的目标位置为左侧第1位。
在实际应用中，可以是每个供电导轨都对应一个位置分布信息，也可以是所有供电导轨对应同一个位置分布信息，位置分布信息可以实现判断电子价签是否在正确位置的功能。
在本说明书一实施例中，获取供电导轨A对应的位置分布信息，根据电子价签的定位标记信息，即位置编码0000，在位置分布信息中进行查找，查找到对应的位置编码0000的安装位置在在供电导轨A的最左侧，则确定电子价签1在供电导轨A上的目标位置为供电导轨的最左侧。
在实际应用中，当电子价签安装在供电导轨上进行上电或电子价签通过自身供电启动之后，电子价签即可立即进入识别位置编码的工作状态，获取到所在位置的位置编码，而在识别过程中，若电子价签识别到多个位置编码，即位置编码发生变化，说明电子价签处于位置编码黑白交替的区域，则在位置编码发生变化时，可以利用一位或多位标志线状态的变化进一步准确的判断出电子价签的目标位置。
具体地，所述电子价签，在初始安装于所述供电导轨，基于所述光电对管读取定位标记变化信息，并根据所述定位标记变化信息确定目标定位标记信息。
其中，定位标记变化信息可以理解为电子价签的定位标记信息的变化过程信息，例如，电子价签识别出位置编码从0001变化至0010，则可以确定电子价签安装时处于这两个位置编码对应的黑白交替的区域。当电子价签位于位置编码对应的黑白交替的区域时，根据根据对应的定位标记变化信息进一步判断出电子价签的实际位置。
在实际应用中，当电子价签刚安装至供电导轨上时，电子价签基于光电对管读取的定位标记信息可能会发生变化，确定电子价签在供电导轨的目标位置还需要根据电子价签的安装方向确定，参见图4，图4示出了本说明书一实施例提供的一种电子价签安装示意图，其中，安装方向是顺时针安装电子价签至供电导轨上，图4中的定位标记变化信息为0001-0010，对于出现变化的位置编码是高1-2位的话，取最终状态的前一种状态作为位置编码逻辑状态，对于出现变化的位置编码时高3-4位的话，取最终状态作为位置编码逻辑状态，图4中由于是第3位发生变化，则取最终状态作为位置编码逻辑状态，则电子价签对应的定位标记信息为0010，根据当前定位标记信息确定电子价签在供电导轨的目标位置。
在本说明书一实施例中，在电子价签1安装在供电导轨时，是按照逆时针方向安装，获取到电子价签1的定位标记信息之后，发现电子价签1的定位标记信息发生变化，定位标记变化信息为0111-1000，确定出电子价签1对应的目标定位标记信息为“0111”，根据目标定位标记信息确定电子价签1在供电导轨上的目标位置。
具体地，所述定位标记变化信息中包括至少两个定位标记信息；
所述电子价签，根据所述定位标记变化信息确定目标定位标记信息，包括：
所述电子价签，根据所述至少两个定位标记变化信息计算目标定位标记信息。
其中，定位标记变化信息中包括至少两个定位标记信息，参见图4，图4中的定位标记变化信息包括0001-0000-0010，目标定位标记信息可以理解为根据定位标记变化信息中 的最后两种状态的定位标记信息，计算出的最终电子价签对应的定位标记信息。
在实际应用中，计算电子价签的目标定位标记信息需要根据安装方向确定，在顺时针安装的情况下，对于出现变化的位置编码是高1-2位的话，取最终状态的前一种状态作为位置编码逻辑状态，对于出现变化的位置编码时高3-4位的话，取最终状态作为位置编码逻辑状态。例如，顺时针安装电子价签，电子价签对应的定位标记变化信息为“0001-0010”，则计算出的目标定位标记信息为“0010”，根据目标定位标记信息确定电子价签在供电导轨上的目标位置。
在本说明书一实施例中，沿用上例，根据电子价签1的定位标记变化信息计算出电子价签1的目标定位标记信息为“0111”，则根据目标定位标记信息确定电子价签1在供电导轨上的目标位置，目标位置为电子价签在0111对应的安装位置，即左数第8位。
本说明书提供的一种位置识别方法，应用于位置识别系统，所述系统包括设置有定位标记信息的供电导轨、以及安装在所述供电导轨上的电子价签，且所述电子价签中设置有光电对管，其中，所述电子价签，基于所述光电对管读取对应的所述供电导轨上的定位标记信息，并根据所述定位标记信息，确定在所述供电导轨的目标位置。本方法基于现有的供电导轨和电子价签进行低成本改造，在供电导轨上配置二进制位置编码，在电子价签上配置光电对管，使电子价签基于光电对管读取在供电导轨上所在位置的二进制位置编码，从而确定自身所在位置，达到电子价签自定位的目的，并且本方法不受环境因素等影响，从而可以定位精确度。
下述结合附图5，以本说明书提供的位置识别方法在商超货架的应用为例，对所述位置识别方法进行进一步说明。其中，图5示出了本说明书一个实施例提供的一种位置识别方法的处理过程流程图，具体步骤包括步骤502至步骤508。
步骤502：所述供电导轨，为所述供电导轨上的电子价签供电。
其中，供电导轨为商超中某个货架上的供电导轨，该供电导轨上安装有3个电子价签，分别是电子价签1、电子价签2以及电子价签3。每个电子价签安装在不同的安装位置，每个安装位置对应一个二进制位置编码。
步骤504：所述电子价签，在确定所述供电导轨供电的情况下，确定安装在所述供电导轨的安装位置。
其中，该供电导轨在为3个电子价签供电之后，这3个电子价签立即进入位置识别的工作状态，每个电子价签都会确定自身的安装位置，电子价签1确定安装在供电导轨的安装位置1，电子价签2确定安装在供电导轨的安装位置2，电子价签3确定安装在供电导轨的安装位置3。
步骤506：所述电子价签，基于所述光电对管读取与所述安装位置对应的定位标记信息。
其中，由于供电导轨上只设置了3个可安装位置，因此该供电导轨上的定位标记信息 设置为2位二进制位置编码，从而确保每个可安装位置都对应不同的二进制位置编码，所以每个电子价签上安装有2路光电对管。电子价签1基于光电对管读取安装位置对应的定位标记信息，为二进制位置编码00；电子价签2基于光电对管读取安装位置对应的定位标记信息，为二进制位置编码01；电子价签3基于光电对管读取安装位置对应的定位标记信息，为二进制位置编码10。
步骤508：所述电子价签，根据所述定位标记信息，确定在所述供电导轨的目标位置。
其中，电子价签1读取二进制位置编码00之后，将二进制位置编码00转换成十进制位置编码0，则确定电子价签1在供电导轨的目标位置为第0位，即左侧第1位。电子价签2读取二进制位置编码01之后，将二进制位置编码01转换成十进制位置编码1，则确定电子价签1在供电导轨的目标位置为第1位，即左侧第2位。电子价签3读取二进制位置编码10之后，将二进制位置编码10转换成十进制位置编码2，则确定电子价签1在供电导轨的目标位置为第2位，即左侧第3位。后续可以基于电子价签与商品的对应关系，进一步判断电子价签是否与商品的对应关系是正确无误的。
