具体实施方式
为使本发明的目的、技术方案和优点更加清楚明白，下面结合实施方式和附图，对本发明做进一步详细说明。在此，本发明的示意性实施方式及其说明用于解释本发明，但并不作为对本发明的限定。
发明人发现：现有技术中通过对商超内所有的电子价签进行重新定位，来发现电子价签位置变化的方案，不仅不能及时地发现价签位置变化，而且对位置不变的价签启动重新定位，也会大大浪费电子价签及***的功耗，降低价签的使用寿命。
由于发明人发现以上技术问题，针对商超环境的全场电子价签，提出了一种可以自动检测电子价签位置移动的方法，再对有位置变化的价签进行针对性的重新定位，实时性更高，降低电子价签及***功耗，延长电子价签的使用寿命。下面对该检测电子价签位置变化的方案进行详细介绍如下。
图1是本发明实施例中检测电子价签位置变化的方法的流程示意图，如图1所示，该方法包括如下步骤：
步骤101：控制器发送检测模式启动指令至预设数量的第一电子价签和第二电子价签；
步骤102：第一电子价签在接收到检测模式启动指令后，发送第一电子价签的身份信息；
步骤103：第二电子价签根据检测模式启动指令，在预设检测时间段内，接收相邻电子价签的身份信息，将接收到的相邻电子价签的身份信息发送至控制器；
步骤104：控制器根据第二电子价签接收到的相邻电子价签的身份信息，以及预先存储的第二电子价签与相邻第一电子价签的身份信息的关系，确定第二电子价签的位置变化情况，在确定出第二电子价签的位置发生变化时，对第二电子价签进行重新定位。
如图1和图8所示，本发明实施例提供的检测电子价签位置变化的方法，工作时：
首先，控制器可以通过基站发送检测模式启动指令至预设数量的第一电子价签和第二电子价签，即控制大量的第一电子价签和第二电子价签进入检测模式。
其次，每一第一电子价签在接收到检测模式启动指令后，分时隙错开发送第一电子价签的身份信息，该身份信息可以是电子价签编码等，此时，多个第一电子价签为处于发送模式的电子价签；第二电子价签根据检测模式启动指令，在预设检测时间段内，即在检测时间窗内，接收所有相邻电子价签的身份信息，将接收到的相邻电子价签的身份信息可以通过一基站发送至控制器(控制中心)，此时，第二电子价签为处于接收模式的电子价签，如果第二电子价签的位置未发生变化，那么接收到的是预先存储的相邻第一电子价签的身份信息，如果第二电子价签的位置发生了变化，那么接收到的就可能与预先存储的相邻第一电子价签的身份信息有区别的电子价签的身份信息。
接着，控制器根据第二电子价签接收到的相邻电子价签的身份信息，以及预先存储的第二电子价签与相邻第一电子价签身份信息的关系，确定第二电子价签的位置变化情况；该第二电子价签与相邻第一电子价签身份信息的关系可以是一张表格或图表等，该关系中存储了与第二电子价签相邻的第一电子价签身份信息，该关系的示意可以如下表1所示。控制器可以将第二电子价签接收到的相邻电子价签的身份信息到上述关系中去匹配，如果第二电子价签接收到的相邻电子价签的身份信息与该关系中的相邻第一电子价签身份信息匹配不一致，那么第二电子价签的位置发生了变化。
Figure PCTCN2019084902-appb-000001
表1
与现有技术中，对商超内所有电子价签全部进行重新定位检测电子价签位置发生变化的方案相比较，本发明实施例提供的技术方案实现了无需对商超内所有的电子价签进行重新定 位，即可基于电子价签的相邻电子价签的信息变化情况，及时地检测出发生位置变化的电子价签，并对发生位置变化的电子价签进行针对性地重新定位即可，节省了位置没有变化的电子价签的功耗及***功耗，延长了电子价签的使用寿命。
具体实施时，该检测电子价签位置变化的方法可以应用于下文提到的检测电子价签位置变化的***。
下面再对本发明实施例涉及检测电子价签位置变化的方法的各个步骤进行详细介绍如下。
在一个实施例中，第二电子价签根据检测模式启动指令，在预设检测时间段内，接收相邻电子价签的身份信息，将接收到的相邻电子价签的身份信息发送至控制器，包括：
第二电子价签根据检测模式启动指令，在预设检测时间段内，接收相邻电子价签的身份信息，估计相邻电子价签的信号功率，将接收到的相邻电子价签的身份信息及估计出的相邻电子价签的信号功率发送至控制器；
控制器根据第二电子价签接收到的相邻电子价签的身份信息，以及预先存储的第二电子价签与相邻第一电子价签的身份信息的关系，确定第二电子价签的位置变化情况，包括：
控制器根据第二电子价签接收到的相邻电子价签的身份信息、估计出的相邻电子价签的信号功率，以及预先存储的第二电子价签与相邻第一电子价签的身份信息及信号功率的关系，确定第二电子价签的位置变化情况。
具体实施时，第二电子价签根据检测模式启动指令，在预设检测时间段内，除了接收相邻电子价签的身份信息，还需要估计相邻电子价签的信号功率；控制器在判断第二电子价签的相邻第一电子价签的变化情况时，除了根据电子价签的身份信息，还需要结合信号功率信息，提高了检测电子价签位置变化的准确性。
具体实施时，上述预先存储的第二电子价签与相邻第一电子价签的身份信息及信号功率的关系也可以是如上表1所示的表格，在此不再举例。
在一个实施例中，控制器根据第二电子价签接收到的相邻电子价签的身份信息、估计出的相邻电子价签的信号功率，以及预先存储的第二电子价签与相邻第一电子价签的身份信息及信号功率的关系，确定第二电子价签的位置变化情况，包括：
控制器将第二电子价签接收到的相邻电子价签的身份信息与所述关系中的第一电子价签的身份信息进行比对，将第二电子价签估计出的相邻电子价签的信号功率与所述关系中的信号功率进行比对；
在第二电子价签接收到的相邻电子价签的身份信息与所述关系中的第一电子价签的身份信息不一致时，或在第二电子价签接收到的相邻电子价签的身份信息与所述关系中的第一电 子价签的身份信息一致，且第二电子价签估计出的相邻电子价签的信号功率与所述关系中的信号功率之间的功率差值大于预设功率阈值时，控制器确定第二电子价签的位置发生变化。
具体实施时，在判断第二电子价签的相邻第一电子价签的信息变化情况时，该变化情况可以包括如下几种情况：
示例1：如图2所示，如果第二电子价签(1号电子价签)接收到的相邻电子价签的身份信息为2号电子价签、3号电子价签、4号电子价签、5号电子价签和6号电子价签，这与存储在上述关系中与第二电子价签相邻的第一电子价签身份信息一致，并且接收功率差值(第二电子价签估计出的相邻电子价签的信号功率与所述关系中的信号功率之间的功率差值)小于阈值，那么确定第二电子价签的位置未发生变化。
示例2：如图3所示，如果第二电子价签接收到的相邻电子价签的身份信息为7号电子价签、8号电子价签、9号电子价签、10号电子价签、11号电子价签、12号电子价签，这与存储在上述关系中与第二电子价签相邻的第一电子价签身份信息不一致，那么确定第二电子价签(1号)的位置发生变化，有可能被移动了。
示例3：经过对比匹配，虽然第二电子价签接收到的相邻电子价签的身份信息为2号电子价签、3号电子价签、4号电子价签、5号电子价签，然而，经过比对，第二电子价签接收到的相邻电子价签的信号功率发生了变化，如果功率变化情况超过预设变化阈值(即第二电子价签估计出的相邻电子价签的信号功率与所述关系中的信号功率之间的功率差值大于预设功率阈值)，即变化较大，就确定第二电子价签的位置发生了变化，有针对性地对发生位置变化的第二电子价签进行重新定位，降低了功耗及提高了检测电子价签位置变化的准确性。
下面再结合图4举一实例，以说明本发明如何实施。
检测价签位置移动(变化)的方法可以包括如下几个步骤：
1.控制中心(控制器)通过基站设备控制大量的模块A(第一电子价签)和模块B(第二电子价签)进入检测模式(可以通过发送检测模式启动指令的方式)；
2.模块A按照控制信息(检测模式启动指令)在同步时间点开始分时隙错开发送自己的身份信息(第一电子价签的身份信息)；
3.模块B按照控制信息(检测模式启动指令)在同步时间点开始在检测时间窗内，接收所有模块A发送的身份信息(如果第二电子价签的位置发生了变化，接收的不是模块A的身份信息，而是位置发生变化之后的相邻的电子价签的身份信息)；
4.检测时间窗结束后，模块B将收到的模块A身份和信号功率通过基站设备发送给控制中心；
5.控制中心收集所有模块B上报的邻居模块A的信息(如果第二电子价签的位置发生 了变化，接收的不是模块A的身份信息，而是位置发生变化之后的相邻的电子价签的身份信息)，并按照一定周期重复上述步骤，并判断邻居模块A的信息是否有变化，并且变化是否超过设定的门限；
6.如果超过设定门限(预设阈值)，控制中心则认为模块B有位置变化，启动重新定位。
通过上述方案，可以基于电子价签的相邻电子价签的信息变化情况，自动实时地检测价签位置移动，对有位置移动的价签进行有针对性的重新定位，降低电子价签及***功耗，提高电子价签使用寿命。
基于同一发明构思，本发明实施例中还提供了一种检测电子价签位置变化的方法，该方法可以应用于下面实施例介绍的控制器，如下面的实施例所述。由于该检测电子价签位置变化的方法解决问题的原理与上述应用于检测电子价签位置变化的***的方法相似，因此该检测电子价签位置变化的方法的实施可以参考上述应用于检测电子价签位置变化的***的方法实施，重复之处不再赘述。以下所使用的，术语“模块”或者“单元”可以实现预定功能的软件和/或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来实现，但是硬件，或者软件和硬件的组合的实现也是可能并被构想的。
图5是本发明实施例中检测电子价签位置变化的方法的流程示意图，该方法可以应用于下面实施例介绍的控制器，如图5所示，该方法包括如下步骤：
步骤201：发送检测模式启动指令至预设数量的第一电子价签和第二电子价签；
步骤202：接收第二电子价签根据检测模式启动指令，在预设检测时间段内，反馈的相邻电子价签的身份信息；
步骤203：根据第二电子价签接收到的相邻电子价签的身份信息，以及预先存储的第二电子价签与相邻第一电子价签的身份信息的关系，确定第二电子价签的位置变化情况；
步骤204：在确定出第二电子价签的位置发生变化时，对第二电子价签进行重新定位。
在一个实施例中，接收第二电子价签根据检测模式启动指令，在预设检测时间段内，反馈的相邻电子价签的身份信息，可以包括：
接收第二电子价签根据检测模式启动指令，在预设检测时间段内，反馈的相邻电子价签的身份信息和信号功率；
根据第二电子价签接收到的相邻电子价签的身份信息，以及预先存储的第二电子价签与相邻第一电子价签的身份信息的关系，确定第二电子价签的位置变化情况，可以包括：
根据第二电子价签接收到的相邻电子价签的身份信息、估计出的相邻电子价签的信号功率，以及预先存储的第二电子价签与相邻第一电子价签的身份信息及信号功率的关系，确定 第二电子价签的位置变化情况。
具体实施时，控制器除了接收第二电子价签收到的第一电子价签的身份信息，还接收第二电子价签估计出的信号功率；并且控制器在判断第二电子价签的相邻第一电子价签的变化情况时，除了根据电子价签的身份信息，还结合信号功率，进一步提高了检测电子价签位置变化的准确性。
在一个实施例中，根据第二电子价签接收到的相邻电子价签的身份信息、估计出的相邻电子价签的信号功率，以及预先存储的第二电子价签与相邻第一电子价签的身份信息及信号功率的关系，确定第二电子价签的位置变化情况，可以包括：
将第二电子价签接收到的相邻电子价签的身份信息与所述关系中的第一电子价签的身份信息进行比对，将第二电子价签估计出的相邻电子价签的信号功率与所述关系中的信号功率进行比对；
在第二电子价签接收到的相邻电子价签的身份信息与所述关系中的第一电子价签的身份信息不一致时，或在第二电子价签接收到的相邻电子价签的身份信息与所述关系中的第一电子价签的身份信息一致，且第二电子价签估计出的相邻电子价签的信号功率与所述关系中的信号功率之间的功率差值大于预设功率阈值时，确定第二电子价签的位置发生变化。
具体实施时，控制器根据身份信息及信号功率的变化情况，例如信号功率对应的信号强度，发现第二电子价签与相邻第一电子价签的距离发生了变化，如果信息变化情况超过预设变化阈值，即超出变化较大，就需要确定第二电子价签的位置发生了变化，有针对性地对发生位置变化的第二电子价签进行重新定位，进一步降低了功耗及提高了检测电子价签位置变化的准确性。
基于同一发明构思，本发明实施例中还提供了一种检测电子价签位置变化的方法，该方法可以应用于下面实施例介绍的电子价签(第一电子价签)，如下面的实施例。由于该检测电子价签位置变化的方法解决问题的原理与上述应用于检测电子价签位置变化的***的方法相似，因此该检测电子价签位置变化的方法的实施可以参考上述应用于检测电子价签位置变化的***的方法的实施，重复之处不再赘述。以下所使用的，术语“模块”或者“单元”可以实现预定功能的软件和/或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来实现，但是硬件，或者软件和硬件的组合的实现也是可能并被构想的。
图6是本发明实施例中应用于第一电子价签的检测电子价签位置变化的方法的流程示意图，如图6所示，该方法包括如下步骤：
步骤301：接收检测模式启动指令；
步骤302：在接收到检测模式启动指令后，发送第一电子价签的身份信息。
