Description

电子货架标签定位系统及方法、电子货架标签及导轨 技术领域
本发明涉及电子价签技术领域,尤其涉及电子货架标签定位系统及方法、电子货架标签及导轨。
背景技术
本部分旨在为权利要求书中陈述的本发明实施例提供背景或上下文。此处的描述不因为包括在本部分中就承认是现有技术。
电子货架标签应用于零售商超可以实现价格的灵活管理,同时零售商对于电子价签实现定位功能有明确需求。获取电子价签的准确位置,对零售商和消费者都有重要价值。从零售商管理角度,可以利用准确的位置信息,生成优化的拣货和补货路径,提高运营效率。消费者可以得到优化的购物路径,提升购物体验。
现有的定位方法包括三角定位。在(x1,y1)(x2,y2)(x3,y3)三个确定位置部署AP,电子价签在位置E接收到来自BS1,BS2,BS3三个AP的无线信号,通过接收信号强度RSSI估算电子价签到BS1,BS2和BS3的距离r1、r2和r3,计算图1中三个圆相交的区域可以获得E点的位置。
三角定位存在如下缺点:实际环境中无线信号存在不确定性,信号的多径和衰落都导致RSSI的大幅变化,难以得到准确的距离值。零售场景由于货架和顾客对信号的遮挡和衰减加剧了无线环境的复杂度,定位精度收到很大影响,一般只能做到几米的精度。商超场景中超过80cm就会导致通道位置错误,这个精度无法满足零售商的需求。
现有的定位方法还包括UWB定位。UWB定位采用TDOA(Time Difference Of Arrival,到达时间差)原理。如图2所示,电子价签以纳秒级窄脉冲重复不间断的广播发送数据帧到周围的模块,每个定位模块利用高敏度的接收器测量数据帧到达接收器天线的时间,利用不同定位基站之间无线电信号传播的时间差,得出电子价签相对于多组定位模块的距离差。根据信号到达两个模块的时间差,则可以确定定位标签位于以这两个模块为焦点的双曲线上。如果有三个以上的基站,则可以建立起多个双曲线方程,这些双曲线方程的交点就是价签的二维坐标位置。
UWB定位存在如下缺点:
1.UWB系统需要单独部署,同时UWB信号衰减更快,需要密集增加定位基站,增加了零售商的设备投入成本。
2.UWB对部署实施要求较高,混凝土墙或金属对UWB信号有强衰减,导致定位精度变差或无法定位。
3.UWB方案在标签侧功耗大,无法满足零售商对于电子货架标签5-10年使用寿命的要求。

导轨标识区安装有身份识别装置,身份识别装置包括导轨ID,导轨ID由无线标签ID号依顺序排列汇总而成。
具体的,所述身份识别装置采用导轨标签;其中,导轨标签内写入导轨ID。所述身份识别装置采用二维码;其中,二维码由导轨ID生成。
具体的,导轨标签和多个无线标签通过粘贴或者侧插方式固定在导轨上。
在本发明实施例中,如图2所示,所述导轨上还包括刻度,用于辅助商品对齐。即可以辅助店员对齐商品。
本发明还提出一种电子货架标签定位系统,如图3所示,包括:上面所述的电子货架标签、上面所述的导轨、PDA和后台服务器;其中导轨安装于商品货架上。
通过绑定导轨ID和货架ID可以得到导轨位置,绑定关系存储到后台服务器。价签安装到导轨,读取导轨上无线标签ID并上传服务器端,通过对比无线标签ID号,获得所在导轨及货架的位置。
具体的,所述PDA用于:扫描商品货架ID和导轨ID,形成货架和导轨ID的绑定关系;扫描电子货架标签ID和商品ID,形成电子货架标签和商品的绑定关系;绑定关系传送至后台服务器;
电子货架标签用于:读取导轨上的无线标签ID并传送至后台服务器;
后台服务器用于:推送商品及价格信息显示在电子货架标签上;基于无线标签ID确定导轨ID,基于货架和导轨ID的绑定关系、导轨ID,确定货架信息,基于货架信息得到对应电子货架标签位置。
其中,PDA(Personal Digital Assistant)个人数字助手。
在本发明实施例中,具体的定位流程如下:
1、导轨制备:将无线标签依次粘贴或侧插固定到导轨标签区域,通过PDA依次读取无线标签ID,汇总后生成导轨ID,将导轨ID写入导轨标签。汇总的导轨ID也可以生成二维码粘贴或侧插固定到导轨标识区。在这个阶段生成该导轨ID和每个无线ID的绑定关系。为达到较好的定位精度,每个无线标签大小在3cm-5cm。
图4中R101内容为T101T102T103T104T105T106T107T108,读取或者扫码一次即可获得该导轨上按顺序排列的所有tag ID。
2、在货架上粘贴门店唯一的条码,可以是一维码、二维码或者RFID标签,作为货架ID标识。参见图5中的S001。
3、导轨绑定:将准备好的导轨安装到货架上,PDA先扫描货架ID,然后依次扫描每层导轨ID,形成货架和导轨ID的绑定关系。由上可知导轨ID和每个无线标签的绑定关系,从而建立起货架ID和无线标签的绑定关系,如表1和图6所示。
表1货架ID和无线标签的绑定关系
位置 导轨ID 无线标签ID
S001货架第四层 R104 T401T402T403T404T405T406T407T408
S001货架第三层 R103 T301T302T303T304T305T306T307T308
S001货架第二层 R102 T201T202T203T204T205T206T207T208
S001货架第一层 R101 T101T102T103T104T105T106T107T108
4、安装电子货架标签,电子货架标签和商品位置遵循从左侧对齐的原则。分别扫描电子货架标签ID和商品ID,形成电子货架标签和商品的绑定关系。绑定信息上传服务器后,服务器推送商品及价格信息显示在电子货架标签上,如图7和表2所示。
表2商品和电子货架标签的绑定关系
电子货架标签 商品
ESL1 商品A
ESL2 商品B
ESL3 商品C
ESL4 商品D
ESL5 商品E
ESL6 商品F
ESL7 商品G
ESL8 商品H
ESL9 商品I
5、后台服务器启动定位,电子货架标签读取导轨无线标签并上报。服务器通过对比导轨ID和无线标签ID绑定关系得到准确导轨ID,再通过导轨ID和货架的绑定关系得到货架信息。这样可以精确得到对应商品的位置信息。
例如图7中第五个电子货架标签ESL5,读取到导轨上的标签ID T204,通过查找表1,可准确得知该货架标签位于S001货架第二层导轨中第四个标签区域。
在本发明实施例中,所述后台服务器还用于:基于电子货架标签和商品的绑定关系、电子货架标签位置,生成商品陈列图,如图8所示。
图9为本发明实施例中电子货架标签定位方法流程图一,如图9所示,该方法包括:
步骤901:PDA扫描商品货架ID和导轨ID,形成货架和导轨ID的绑定关系;扫描电子货架标签ID和商品ID,形成电子货架标签和商品的绑定关系;绑定关系传送至后台服务器;
步骤902:电子货架标签读取导轨上的无线标签ID并传送至后台服务器;
步骤903:后台服务器推送商品及价格信息显示在电子货架标签上;基于无线标签ID确定导轨ID,基于货架和导轨ID的绑定关系、导轨ID,确定货架信息,基于货架信息得到对应电子货架标签位置;
其中,电子货架标签为上面所述的电子货架标签,导轨为上面所述的导轨;导轨安装于商品货架上。
在本发明实施例中,如图10所示,还包括:
步骤1001:后台服务器基于电子货架标签和商品的绑定关系、电子货架标签位置,生成商品陈列图。
