Detailed ways

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.

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:

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;

Step 102: Determine whether the electronic price tag has moved according to the monitored signal strength sequence of the electronic price tag;

Step 103: When the result of the judgment is that the electronic price tag has moved, determine the position of the electronic price tag after the movement according to the signal strength sequence when the heartbeat data of the electronic price tag is received by multiple base station devices at the same time.

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.

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.

In an embodiment, determining that the electronic price tag has moved based on the monitored signal strength sequence of the electronic price tag includes:

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.

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.

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.

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.

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:

Determine multiple moments of continuous duration;

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;

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.

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.

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.

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:

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.

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.

During specific implementation, the positioning matching model can be obtained by various methods, and one of the embodiments is given below.

In an embodiment, the positioning matching model is obtained by the following method:

Obtain the signal strength sequence when the heartbeat data of electronic price tags in different locations are simultaneously received by multiple base stations;

Determine the matching relationship between each position and the signal strength sequence corresponding to the position, and obtain multiple matching relationships;

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;

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.

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.

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:

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;

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;

From the corresponding matching relationship, the position of the electronic price tag after the movement is determined.

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.

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.

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;

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.

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.
