为使本发明实施例的目的、技术方案和优点更加清楚明白,下面结合附图对本发明实施例做进一步详细说明。在此,本发明的示意性实施例及其说明用于解释本发明,但并不作为对本发明的限定。In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following describes the embodiments of the present invention in detail with reference to the accompanying drawings. Here, the illustrative embodiments of the present invention and the description thereof are used to explain the present invention, but not as a limitation to the present invention.
图1为本发明实施例中电子价签移动位置确定方法的流程图,如图1所示,该方法包括:Fig. 1 is a flowchart of a method for determining the moving position of an electronic price tag in an embodiment of the present invention. As shown in Fig. 1, the method includes:
步骤101,监测电子价签的心跳数据同时被多个基站设备接收时的信号强度序列,所述信号强度序列包括多个基站设备对应的信号强度值;Step 101: Monitoring the signal strength sequence when the heartbeat data of the electronic price tag is simultaneously received by multiple base station devices, where the signal strength sequence includes signal strength values corresponding to the multiple base station devices;

在本发明实施例中,监测电子价签的心跳数据同时被多个基站设备接收时的信号强度序列,所述信号强度序列包括多个基站设备对应的信号强度值;根据监测到的电子价签的信号强度序列,判断电子价签是否发生移动;在判断结果为电子价签发生移动时,根据电子价签在移动后的心跳数据同时被多个基站设备接收时的信号强度序列,确定电子价签移动后的位置。以上过程的实现只需要监测电子价签的心跳数据同时被多个基站设备接收时的信号强度序列,即可确定电子价签的移动后的位置,不需要用到ibeacon、uwb和wifi等技术,因此经济成本低。In the embodiment of the present invention, the signal strength sequence when the heartbeat data of the electronic price tag is simultaneously received by multiple base station devices is monitored, and the signal strength sequence includes the signal strength values corresponding to the multiple base station devices; according to the monitored electronic price tag Determine whether the electronic price tag has moved; when the result of the judgment is that the electronic price tag has moved, determine the electronic price according to the signal strength sequence when the heartbeat data of the electronic price tag is simultaneously received by multiple base stations The position of the sign after the move. The realization of the above process only needs to monitor the signal strength sequence when the heartbeat data of the electronic price tag is received by multiple base station equipment at the same time, and then the position of the electronic price tag after the movement can be determined. It does not need to use ibeacon, uwb and wifi technologies. Therefore, the economic cost is low.
在步骤101中,需要监测监测电子价签的心跳数据同时被多个基站设备接收时的信号强度序列,所述信号强度序列包括多个基站设备对应的信号强度值,监测过程可以由计算设备完成,例如控制模块,其中,电子价签的心跳数据首先发送到多个基站设备中,电子价签可以有一至多个,基站设备可以有多个,图2为本发明实施例中电子价签、基站设备和控制模块之间的通信关系,如图2所示,一个电子价签的心跳数据可以发送至多个基站设备,且可以周期性地在公共信道上发送心跳数据,距离近的基站设备接收到的信号强度值大,距离远的基站设备接收到的信号强度值小;一个基站设备也可以获得接收多个电子价签的心跳数据,且可以持续接收多个电子价签的心跳数据,因此,对于一个电子标签来说,该电子价签的心跳数据被一个基站设备接收时会产生一个信号强度值,因此,多个基站设备的心跳数据同时被多个基站设备接收时,会产生多个信号强度值,多个信号强度值形成信号强度序列,每个基站设备将接收该电子价签时的信号强度值发送至控制模块,因此,控制模块在同一时刻会监测到电子价签的心跳数据同时被多个基站设备接收时的信号强度序列,控制模块在每一时刻即获得了监测到的电 子价签的信号强度序列,通过持续监测,可持续获得监测到的电子价签的信号强度序列,一个电子价签对应一个信号强度序列。在步骤102中,根据监测到的电子价签的信号强度序列,判断电子价签是否发生移动。在步骤103中,在判断结果为电子价签发生移动时,即可根据电子价签移动后的心跳数据同时被多个基站设备接收时的信号强度序列,确定电子价签移动后的位置。可以看到,以上确定价签移动后的位置的过程不需要用到ibeacon、uwb和wifi等技术,经济成本低。In step 101, it is necessary to monitor the signal strength sequence when the heartbeat data of the electronic price tag is simultaneously received by multiple base station devices. The signal strength sequence includes the signal strength values corresponding to multiple base station devices. The monitoring process can be completed by the computing device For example, in the control module, the heartbeat data of the electronic price tag is first sent to multiple base station devices. There can be one or more electronic price tags, and there can be multiple base station devices. Figure 2 shows the electronic price tag and base station in the embodiment of the present invention. The communication relationship between the device and the control module is shown in Figure 2. The heartbeat data of an electronic price tag can be sent to multiple base station devices, and the heartbeat data can be sent periodically on a common channel, and the base station device close to it can receive it. The signal strength value of is large, and the signal strength value received by the base station equipment far away is small; a base station equipment can also receive the heartbeat data of multiple electronic price tags, and can continuously receive the heartbeat data of multiple electronic price tags, therefore, For an electronic tag, the heartbeat data of the electronic price tag will generate a signal strength value when received by a base station device. Therefore, when the heartbeat data of multiple base station devices are received by multiple base station devices at the same time, multiple signals will be generated Strength value. Multiple signal strength values form a signal strength sequence. Each base station device sends the signal strength value when receiving the electronic price tag to the control module. Therefore, the control module will monitor the heartbeat data of the electronic price tag at the same time. The signal strength sequence when received by multiple base station equipment, the control module obtains the signal strength sequence of the monitored electronic price tag at every moment. Through continuous monitoring, the signal strength sequence of the monitored electronic price tag can be continuously obtained. An electronic price tag corresponds to a signal strength sequence. In step 102, it is determined whether the electronic price tag has moved based on the monitored signal strength sequence of the electronic price tag. In step 103, when the result of the judgment is that the electronic price tag has moved, the position of the electronic price tag after the movement can be determined based on the signal strength sequence when the heartbeat data after the electronic price tag is moved simultaneously received by multiple base station devices. It can be seen that the above process of determining the position of the price tag does not need to use technologies such as ibeacon, uwb, and wifi, and the economic cost is low.
具体实施时,根据监测到的电子价签的信号强度序列,判断电子价签是否发生移动的方法可以有多种,下面给出其中一种实施例。During specific implementation, there may be multiple methods for judging whether the electronic price tag has moved according to the monitored signal strength sequence of the electronic price tag, and one of the embodiments is given below.
在一实施例中,根据监测到的电子价签的信号强度序列,确定电子价签发生移动,包括:In an embodiment, determining that the electronic price tag has moved based on the monitored signal strength sequence of the electronic price tag includes:
与在初始位置时的电子价签的心跳数据同时被多个基站设备接收时的信号强度序列相比,若设定监测时长内监测到的电子价签的心跳数据同时被多个基站设备接收时的信号强度序列中超过设定个数的信号强度值发生变化,且变化范围超过第一设定强度变化范围,则判断结果为电子价签发生移动,否则判断结果为电子价签未发生移动。Compared with the signal strength sequence when the heartbeat data of the electronic price tag at the initial position is received by multiple base station devices at the same time, if the heartbeat data of the electronic price tag monitored during the set monitoring period is received by multiple base station devices at the same time If the signal strength value of the signal strength sequence exceeds the set number changes, and the change range exceeds the first set strength change range, the judgment result is that the electronic price tag has moved, otherwise the judgment result is that the electronic price tag has not moved.
在上述实施例中,首先获得在初始位置时的电子价签的心跳数据同时被多个基站设备接收时的信号强度序列,在步骤101中,控制模块在同一时刻会监测到电子价签的心跳数据同时被多个基站设备接收时的信号强度序列,即获得了电子价签在初始位置时的信号强度序列,一个电子价签对应一个信号强度序列。In the above embodiment, first obtain the signal strength sequence when the heartbeat data of the electronic price tag at the initial position is received by multiple base station devices at the same time. In step 101, the control module will monitor the heartbeat of the electronic price tag at the same time. The signal strength sequence when the data is received by multiple base station devices at the same time, that is, the signal strength sequence when the electronic price tag is at the initial position is obtained, and one electronic price tag corresponds to a signal strength sequence.
控制模块持续监测电子标签的信号强度序列,价签位置不移动的条件下,长期多次监测到的电子价签的信号强度序列中的信号强度值的平均值波动幅度很小,不超过3dB,因此,最好以设定监测时长内监测到的信号强度序列来判断,设定监测时长可以是10分钟,也可以是1小时,可以根据具体情况来定。设定个数可以是基站设备的数量的一半,举一例,一电子价签向10个基站发送心跳数据,即信号强度序列中的信号强度值为10个,设定个数可以是5个,当然,也可以大于或小于5个,可以根据具体情况来定。The control module continuously monitors the signal strength sequence of the electronic tag. Under the condition that the position of the price tag does not move, the average value of the signal strength value in the signal strength sequence of the electronic price tag monitored many times for a long time fluctuates very little, not exceeding 3dB. Therefore, it is best to judge by the signal strength sequence monitored during the set monitoring period. The set monitoring period can be 10 minutes or 1 hour, which can be determined according to the specific situation. The set number can be half of the number of base station equipment. For example, an electronic price tag sends heartbeat data to 10 base stations, that is, the signal strength value in the signal strength sequence is 10, and the set number can be 5. Of course, it can also be greater than or less than 5, depending on the specific situation.
若设定监测时长内监测到的电子价签的心跳数据同时被多个基站设备接收时的信号强度序列中超过设定个数的信号强度值发生变化,且变化范围超过第一设定强度变化范围,则判断结果为电子价签发生移动。例如,第一设定强度变化范围可以大于5dB,可以根据具体情况来定。若设定监测时长内监测到的电子价签的心跳数据同时被多个基站设备接收时的信号强度序列中超过设定个数的信号强度值发生变化,且变化范围超过第 一设定强度变化范围,则确定电子价签发生移动,举一例,在1小时内,监测到的电子价签的信号强度序列中有一半的信号强度值发生变化,且变化范围大于5dB,可以确定电子价签发生移动。If the heartbeat data of the electronic price tag monitored during the set monitoring period is simultaneously received by multiple base station equipment, the signal strength value exceeding the set number in the signal strength sequence changes, and the change range exceeds the first set strength change Range, the judgment result is that the electronic price tag has moved. For example, the first set intensity variation range may be greater than 5dB, which may be determined according to specific conditions. If the heartbeat data of the electronic price tag monitored during the set monitoring period is simultaneously received by multiple base station equipment, the signal strength value exceeding the set number in the signal strength sequence changes, and the change range exceeds the first set strength change Range, it is determined that the electronic price tag has moved. For example, within 1 hour, half of the signal strength value in the signal strength sequence of the monitored electronic price tag has changed, and the change range is greater than 5dB, it can be determined that the electronic price tag has occurred mobile.
在一实施例中,电子价签在移动后的心跳数据同时被多个基站设备接收时的信号强度序列采用如下方法获得:In one embodiment, the signal strength sequence of the moved heartbeat data of the electronic price tag when simultaneously received by multiple base station devices is obtained by the following method:
确定连续时长的多个时刻;Determine multiple moments of continuous duration;
获得在每一时刻下,电子价签的心跳数据同时被多个基站设备接收时的信号强度序列;Obtain the signal strength sequence when the heartbeat data of the electronic price tag is simultaneously received by multiple base station equipment at each moment;
若每一信号强度序列中的信号强度值均在第二设定强度变化范围内,计算多个信号强度序列的平均值,确定所述平均值为电子价签在移动后的心跳数据同时被多个基站设备接收时的信号强度序列。If the signal strength value in each signal strength sequence is within the second set strength change range, calculate the average value of multiple signal strength sequences, and determine that the average value is the heartbeat data of the electronic price tag after the movement is simultaneously increased. The signal strength sequence when receiving by a base station equipment.
在上述实施例中,连续时长可以是1小时等根据具体情况来确定的时长,在该连续时长内,取多个时刻,在每一时刻,对每一电子价签,获得电子价签的心跳数据同时被多个基站设备接收时的信号强度序列。电子价签移动后的信号强度序列是指电子价签在移动后稳定的信号强度序列,即在电子价签停止移动后,信号强度值在持续时长内都处于稳定的情况。第二设定强度变化范围可以为小于3dB,当然,也可以是根据具体情况来确定的其他范围值;在每一时刻,若上述该电子价签的心跳数据同时被多个基站设备接收时的信号强度序列中的信号强度值均在第二设定强度变化范围内,例如均小于3dB,则可确定该电子价签的信号强度序列稳定,此时计算多个时刻对应的多个信号强度序列的平均值,确定所述平均值为电子价签移动后的信号强度序列。In the above embodiment, the continuous duration may be a duration determined according to specific circumstances such as 1 hour. Within the continuous duration, multiple moments are taken. At each moment, for each electronic price tag, the heartbeat of the electronic price tag is obtained. The signal strength sequence when data is received by multiple base station equipment at the same time. The signal strength sequence after the electronic price tag moves refers to the stable signal strength sequence of the electronic price tag after the movement, that is, after the electronic price tag stops moving, the signal strength value is stable for the duration. The second set intensity variation range can be less than 3dB, of course, it can also be other range values determined according to the specific situation; at each moment, if the heartbeat data of the electronic price tag is received by multiple base station devices at the same time The signal strength values in the signal strength sequence are all within the second set strength variation range, for example, all are less than 3dB, then the signal strength sequence of the electronic price tag can be determined to be stable, and then multiple signal strength sequences corresponding to multiple moments are calculated Determine the average value of the signal strength sequence after the electronic price tag moves.
具体实施时,根据电子价签在移动后的心跳数据同时被多个基站设备接收时的信号强度序列,确定电子价签移动后的位置的方法可以有多种,下面给出其中一个实施例。In specific implementation, according to the signal strength sequence when the heartbeat data of the electronic price tag is simultaneously received by multiple base station devices, there may be multiple methods for determining the position of the electronic price tag after the movement. One embodiment is given below.
在一实施例中,根据电子价签在移动后的心跳数据同时被多个基站设备接收时的信号强度序列,确定电子价签移动后的位置,包括:In an embodiment, determining the position of the electronic price tag after moving based on the signal strength sequence when the heartbeat data of the electronic price tag after being moved is simultaneously received by multiple base station devices, including:
将电子价签在移动后的心跳数据同时被多个基站设备接收时的信号强度序列,输入至定位匹配模型,确定电子价签移动后的位置,所述定位匹配模型包括电子价签的位置和信号强度序列的匹配关系。The heartbeat data of the electronic price tag after the movement is received by multiple base station equipment at the same time the signal strength sequence is input into the positioning matching model to determine the position of the electronic price tag after the movement. The positioning matching model includes the position of the electronic price tag and The matching relationship of the signal strength sequence.
在上述实施例中,定位匹配模型包括电子价签的位置和信号强度序列的匹配关系,因此,在获得一个电子价签在移动后的心跳数据同时被多个基站设备接收时的信号强度序列,即可获得对应的电子价签的位置。In the above embodiment, the positioning matching model includes the matching relationship between the position of the electronic price tag and the signal strength sequence. Therefore, the signal strength sequence when the heartbeat data of an electronic price tag after moving is simultaneously received by multiple base stations is obtained, You can get the location of the corresponding electronic price tag.
具体实施时,定位匹配模型可以采用多种方法获得,下面给出其中一个实施例。During specific implementation, the positioning matching model can be obtained by various methods, and one of the embodiments is given below.
在一实施例中,所述定位匹配模型采用如下方法获得:In an embodiment, the positioning matching model is obtained by the following method:
获得不同位置的电子价签的心跳数据同时被多个基站设备接收时的信号强度序列;Obtain the signal strength sequence when the heartbeat data of electronic price tags in different locations are simultaneously received by multiple base stations;
确定每一位置与该位置对应的信号强度序列的匹配关系,获得多个匹配关系;Determine the matching relationship between each position and the signal strength sequence corresponding to the position, and obtain multiple matching relationships;
根据电子价签的每一位置,和电子价签在每一位置的心跳数据同时被多个基站设备接收时的信号强度序列,获得电子价签的位置与信号强度序列的多个匹配关系;According to each position of the electronic price tag, and the signal strength sequence when the heartbeat data of each position of the electronic price tag is simultaneously received by multiple base stations, multiple matching relationships between the position of the electronic price tag and the signal strength sequence are obtained;
将多个匹配关系分为多个匹配关系群组,确定所述多个匹配关系群组为定位匹配模型,其中,若电子标签的相邻位置之间的距离在设定距离范围内,则电子标签的相邻位置对应的匹配关系在一个匹配关系群组内。The multiple matching relationships are divided into multiple matching relationship groups, and the multiple matching relationship groups are determined to be a positioning matching model, wherein if the distance between adjacent positions of the electronic tag is within a set distance range, the electronic The matching relationship corresponding to the adjacent position of the label is in a matching relationship group.
在上述实施例中,首先获得电子价签的多个位置,所述位置为物理位置,从而可以从不同的位置发出心跳数据,可以把所有电子价签所在的物理位置录入到控制模块;对一个电子价签来说,在每一位置上都有一个对应的信号强度序列,该信号强度序列是电子价签在该位置上时,该电子价签的心跳数据同时被多个基站设备接收时新城的,因此,可每一位置与该位置对应的信号强度序列形成一个匹配关系,多个不同的位置即可形成多个匹配关系,然后对多个匹配关系进行分组,形成多个匹配关系群组,分组的原则是,如果电子标签的相邻位置之间的距离在设定距离范围内,例如,设定距离范围为小于10cm,电子标签的位置1和位置2之间的距离为10cm时,则位置1和位置2形成的匹配关系再一个匹配关系群组里,这些匹配关系群组即为定位匹配模型。In the above-mentioned embodiment, firstly obtain multiple positions of the electronic price tag, which are physical locations, so that heartbeat data can be sent from different positions, and the physical locations of all electronic price tags can be entered into the control module; For electronic price tags, there is a corresponding signal strength sequence at each location. When the electronic price tag is at that location, the heartbeat data of the electronic price tag is simultaneously received by multiple base stations. Therefore, each position can form a matching relationship with the signal strength sequence corresponding to that position, and multiple different positions can form multiple matching relationships, and then group the multiple matching relationships to form multiple matching relationship groups , The principle of grouping is that if the distance between adjacent positions of the electronic tag is within the set distance range, for example, the set distance range is less than 10cm, and the distance between position 1 and position 2 of the electronic tag is 10cm, Then, the matching relationship formed by position 1 and position 2 is in another matching relationship group, and these matching relationship groups are positioning matching models.
在一实施例中,将电子价签在移动后的心跳数据同时被多个基站设备接收时的信号强度序列,输入至定位匹配模型,确定电子价签移动后的位置,包括:In one embodiment, inputting the signal strength sequence of the heartbeat data of the electronic price tag after being moved by multiple base station devices into the positioning matching model to determine the position of the electronic price tag after the movement includes:
从定位匹配模型中的多个匹配关系群组中,确定电子价签在移动后的心跳数据同时被多个基站设备接收时的信号强度序列对应的匹配关系群组;From the multiple matching relationship groups in the positioning matching model, determine the matching relationship group corresponding to the signal strength sequence when the heartbeat data of the electronic price tag is simultaneously received by multiple base station devices after moving;
从所述对应的匹配关系群组中,确定电子价签在移动后的心跳数据同时被多个基站设备接收时的信号强度序列对应的匹配关系;From the corresponding matching relationship group, determine the matching relationship corresponding to the signal strength sequence when the heartbeat data of the electronic price tag after the movement is received by multiple base station devices at the same time;
从所述对应的匹配关系中,确定电子价签移动后的位置。From the corresponding matching relationship, the position of the electronic price tag after the movement is determined.
前面已经得到了定位匹配模型,该定位匹配模型包括多个匹配关系群组,将电子价签在移动后的心跳数据同时被多个基站设备接收时的信号强度序列,输入至定位匹配模型后,根据上述过程可确定电子价签移动后的位置。以上确定电子价签移动后的位置的过程为最短距离匹配运算,通过该最短匹配运算可以减少查找匹配关系的数量,提高运算的效率。The positioning matching model has been obtained above. The positioning matching model includes multiple matching relationship groups. After the heartbeat data of the electronic price tag is received by multiple base stations at the same time, the signal strength sequence is input into the positioning matching model, According to the above process, the position of the electronic price tag after the movement can be determined. The above process of determining the position of the electronic price tag after moving is the shortest distance matching operation, and the shortest matching operation can reduce the number of matching relationships and improve the efficiency of the operation.
具体实施时,基站设备的数量可能非常大,而信号强度序列中的信号强度值的个数对应基站的个数,因此信号强度值也有很多个,信号强度值的个数增加会提高计算准确性,但过多的信号强度值会加重计算的负担,因此,在基站设备的数量非常大时,可减少信号强度序列中的信号强度值的个数,下面给出其中一种减少的方法。In specific implementation, the number of base station equipment may be very large, and the number of signal strength values in the signal strength sequence corresponds to the number of base stations, so there are many signal strength values, and an increase in the number of signal strength values will improve calculation accuracy , But too many signal strength values will increase the burden of calculation. Therefore, when the number of base station equipment is very large, the number of signal strength values in the signal strength sequence can be reduced. One of the reduction methods is given below.
在一实施例中,电子价签的心跳数据同时被多个基站设备接收时的信号强度序列中的多个基站设备对应的信号强度值按照从大到小排序;In an embodiment, the signal strength values corresponding to the multiple base station devices in the signal strength sequence when the heartbeat data of the electronic price tag is simultaneously received by multiple base station devices are sorted from large to small;
若多个基站设备对应的信号强度值的个数超过设定值,信号强度序列包括排序后的前设定值个信号强度值。If the number of signal strength values corresponding to multiple base station devices exceeds the set value, the signal strength sequence includes the sorted previous set value signal strength values.
在上述实施例中,减少信号强度序列中的信号强度值的个数的原理是只取前设定值个较大的信号强度值,因此,首先电子价签的心跳数据同时被多个基站设备接收时的信号强度序列中的多个基站设备对应的信号强度值按照从大到小排序,设定值可以是10个,根据具体情况而定,例如,基站设备超过20个,电子价签的信号强度值的个数超过20,设定值取10,则信号强度序列包括排序后的前10个信号强度值。In the above embodiment, the principle of reducing the number of signal strength values in the signal strength sequence is to only take the previous set value and the larger signal strength value. Therefore, first, the heartbeat data of the electronic price tag is simultaneously transmitted by multiple base station devices. The signal strength values corresponding to multiple base station devices in the signal strength sequence during reception are sorted from largest to smallest. The set value can be 10, depending on the specific situation. For example, if there are more than 20 base station devices, the value of the electronic price tag If the number of signal strength values exceeds 20, and the set value is 10, the signal strength sequence includes the first 10 signal strength values after sorting.
综合上述实施例,下面给出一个实施例,说明电子价签移动位置确定的一个详细流程,图3为本发明实施例中电子价签移动位置确定的一个详细流程图,如图3所示,包括:Based on the above embodiments, an embodiment is given below to illustrate a detailed process of determining the moving position of an electronic price tag.
