Based on the above mobile terminal hardware structure and communication network system, the present invention provides various embodiments of the method.

Fig. 3 is a flowchart of an embodiment of an electronic price tag relay communication method provided by the present application. When the steps are executed, the steps may be executed in sequence as in the flowchart, or multiple steps may be executed simultaneously according to the actual situation, which is not limited herein. The electronic price tag relay communication method comprises the following steps:

step S310, when a base station fails to establish communication connection with at least one target electronic price tag for M times within a first preset time, the base station sets p electronic price tags as relay price tags based on a preset rule;

step S330, the base station sends a communication instruction to the target electronic price tag through the relay price tag;

step S350, when the relay price tag receives the response information of the target electronic price tag within a second preset time, the relay price tag forwards the response information to the base station;

step S370, the base station receives the response information.

Through the embodiment, firstly, when the base station fails to establish communication connection with at least one target electronic price tag for M times within a first preset time, the base station sets p electronic price tags as relay price tags based on a preset rule; secondly, the base station sends a communication instruction to the target electronic price tag through the relay price tag; when the relay price tag receives response information of the target electronic price tag within second preset time, the relay price tag forwards the response information to the base station; and finally, the base station receives the response information, so that when the base station fails to establish communication connection with at least one target electronic price tag for M times within a first preset time, the base station can send a communication instruction to the target electronic price tag through a relay price tag set based on a preset rule, and thus the communication connection with the target electronic price tag is established.

The above steps will be specifically described with reference to specific examples.

In step S310, when the base station fails to establish a communication connection with at least one target electronic price tag M times within a first preset time, the base station sets p electronic price tags as relay price tags based on a preset rule.

In the present embodiment, the first preset time may be set according to actual conditions, for example, 5s, 10s, and the like. M, p may each be a positive integer. M can be set according to actual conditions, for example, 3 times, 4 times and the like.

In this embodiment, the base station may request one or more of the electronic price tags to establish a communication connection to manage the electronic price tags. The electronic price tag may comprise the target electronic price tag. The target electronic price tag may refer to an electronic price tag whose distance from the base station is greater than a preset threshold. When the distance between the base station and the electronic price tags is greater than the preset threshold, the base station and the electronic price tags, that is, the target electronic price tags, may not establish communication connection, so that normal data communication cannot be completed. The preset threshold may be set according to actual conditions, for example, the preset threshold may be two meters, three meters, or the like.

It is to be understood that in other embodiments, the target electronic price tag may also be an electronic price tag satisfying a preset condition. The preset condition can also be set according to the actual situation.

In this embodiment, before the step of setting p electronic price tags as the relay price tag by the base station based on the preset rule when the base station fails to establish the communication connection with at least one target electronic price tag M times within the first preset time, the method further includes:

step S3101, the base station obtains and stores the signal strength of the uplink signal of at least one electronic price tag;

step S3102, the base station calculates an average value of the signal strength of the uplink signal of the last N times per electronic price tag.

Specifically, N may be a positive integer. The base station can acquire and store the signal intensity of the uplink signal of at least one electronic price tag which establishes communication connection with the base station, and then respectively calculate the average value of the signal intensity of the uplink signal of each electronic price tag for the last N times. Taking N as 5 as an example, the base station may obtain and store the signal strength of the uplink signal of at least one electronic price tag, and respectively calculate an average value of the signal strength of the uplink signal of the latest 5 times of each electronic price tag, where the average value of the signal strength of each electronic price tag is the sum of the signal strengths of the uplink signals of 5 times divided by 5.

In other embodiments, the base station may further obtain and store the signal strength of the uplink signal of at least one electronic price tag, and select the signal strength of the uplink signal of each electronic price tag for any N times within a preset time period to calculate an average value of the signal strength of each electronic price tag.

In this embodiment, the base station may further receive price tag information reported by each electronic price tag. The price tag information may further include a current sleep period of the electronic price tag, tag information, a current display state of the electronic price tag being normal or abnormal, a current electric quantity value of the electronic price tag, a position of the electronic price tag, and the like. The tag information may refer to identification information of the electronic price tag, and the identification information may be a mark of each electronic price tag, and is used to identify the electronic price tag. The identification information may be a unique number carried by the electronic price tag when the electronic price tag leaves a factory, a random code automatically generated by the electronic price tag, and a unique code, a character, a number, and the like set by a user for each electronic price tag. It should be noted that the above identification information is only an exemplary illustration, and is not limited thereto.

In this embodiment, the base station may establish a mapping relationship between an average value of signal strengths of a plurality of electronic price tags and tag information of the plurality of electronic price tags, so that in a subsequent step, the base station may search the mapping relationship based on the tag information of the electronic price tags to determine the average value of the signal strengths of the electronic price tags or search the mapping relationship based on the average value of the signal strengths to determine the electronic price tags corresponding to the average value of the signal strengths. It is understood that the mapping relationship between the tag information of the electronic price tag and the average value of the signal intensity of the electronic price tag may be one-to-one or many-to-one.

In this embodiment, the step of setting, by the base station, p electronic price tags as relay price tags based on a preset rule includes:

step S3103, the base station selects p electronic price tags whose signal strength is close to a preset value as the relay price tags based on the preset rule;

In this embodiment, p may be less than or equal to the number of target electron price tags. For example, when the base station fails to establish communication connection with 4 target electronic price tags M times within a first preset time, the base station may select 4, 3, 2, or 1 electronic price tags with signal strength close to a preset value as the relay price tags based on the preset rule.

In this embodiment, the preset rule may be set according to actual requirements, for example, the preset rule may be to select an electronic price tag near the middle position between the base station and the target electronic price tag as the relay price tag. w may also be set according to the actual situation, for example, setting the w to 2, 3, and the like.

In this embodiment, when the base station obtains and stores the signal strength of the uplink signal of at least one electronic price tag, and calculates the average value of the signal strength of the uplink signal of each electronic price tag for the last N times respectively, and when the base station fails to establish communication connection with at least one target electronic price tag after M times within the first preset time, the base station may search the mapping relationship based on the preset rule to select p electronic price tags having signal strengths close to w × u as the relay price tags, so that the electronic price tags which are in good communication with the base station and located at the intermediate positions between the base station and the target electronic price tags may be selected as the relay price tags, so as to implement data communication between the base station and the target electronic price tags through the relay price tags.

In this embodiment, taking the first preset time value as 10s, the M value as 3, the N value as 5, and the w and p values as 2 as an example, the base station may obtain and store the signal strength of the uplink signal of at least one electronic price tag, and calculate an average value u of the signal strength of the uplink signal of the last 5 times of each electronic price tag, and when the base station fails to establish a communication connection with at least one target electronic price tag for 3 times within 10s, 2 electronic price tags close to the middle positions of the base station and the target electronic price tag and having signal strengths close to 2u may be selected as the relay price tag.

In step S330, the base station transmits a communication command to the target electronic price tag through the relay price tag.

In this embodiment, the step of the base station transmitting the communication command to the target electronic price tag through the relay price tag includes:

step S3301, the base station sends a relay command and the communication command to the relay price tag;

and step S3302, the relay price tag receives the relay instruction and the communication instruction, and forwards the communication instruction to the target electronic price tag based on the relay instruction.

In this embodiment, the relay command may include a command to forward the communication command.

In this embodiment, after the step of transmitting the communication command to the target electronic price tag by the base station through the relay price tag, the base station further includes:

and step S3303, determining whether the response information of the target electronic price tag is received within a second preset time.

In the present embodiment, the second preset time may be set according to actual conditions, for example, 10s, 15s, and the like. After the step of sending the communication instruction to the target electronic price tag through the relay price tag, the base station may determine whether the relay price tag receives response information of the target electronic price tag within a second preset time.

In another embodiment, it may be determined whether the base station receives the response information of the target electronic price tag within a second preset time.

In this embodiment, after the step of determining whether the response message of the target electronic price tag is received within the second preset time, the method further includes:

step S3304, when the relay price tag does not receive the response information of the target electronic price tag within the second preset time, the relay price tag sends relay failure information to the base station.

Specifically, the base station may first send a relay instruction and the communication instruction to p relay price tags, where the relay price tags may receive the relay instruction and the communication instruction, forward the communication instruction to the target electronic price tag based on the relay instruction, and then determine whether response information of the target electronic price tag is received within the second preset time. When the relay price tag does not receive the response information of the target electronic price tag within the second preset time, the relay price tag sends relay failure information to the base station, and the base station receives the relay failure information and returns to the step S310 to reset a new relay price tag.

In step S350, when the relay price tag receives the response information of the target electronic price tag within a second preset time, the relay price tag forwards the response information to the base station.

In this embodiment, taking the second preset time as 15s as an example, when it is determined that the relay price tag receives the response information of the target electronic price tag within 15s, the relay price tag may forward the response information to the base station; when it is determined that the relay price tag does not receive the response information of the target electronic price tag within 15s, the relay price tag may transmit relay failure information to the base station.

In step S370, the base station receives the response information.

In this embodiment, when the relay price tag receives the response information of the target electronic price tag within the second preset time, the relay price tag forwards the response information to the base station, and the base station receives the response information, so that a part of the electronic price tags can have a function of a "base station repeater" without adding hardware equipment, a data communication function between the base station and a distant electronic price tag, that is, the target electronic price tag, is realized, and the situation that the communication success rate of the edge electronic price tag is low or normal communication cannot be effectively improved.

when the relay price tag receives response information of the target electronic price tag in a second preset time period, the relay price tag forwards the response information to the base station;

receiving, by the base station, the response information.

In the embodiment, firstly, when a base station fails to establish communication connection with at least one target electronic price tag for M times within a first preset time, the base station sets p electronic price tags as relay price tags based on a preset rule; secondly, the base station sends a communication instruction to the target electronic price tag through the relay price tag; when the relay price tag receives response information of the target electronic price tag within second preset time, the relay price tag forwards the response information to the base station; and finally, the base station receives the response information, so that when the base station fails to establish communication connection with at least one target electronic price tag for M times within a first preset time, the base station can send a communication instruction to the target electronic price tag through a relay price tag set based on a preset rule, and thus the communication connection with the target electronic price tag is established.

In this embodiment, the computer program, when executed by the processor, further implements:

Through the electronic price tag relay communication equipment, firstly, when a base station fails to establish communication connection with at least one target electronic price tag for M times within a first preset time, the base station sets p electronic price tags as relay price tags based on a preset rule; secondly, the base station sends a communication instruction to the target electronic price tag through the relay price tag; when the relay price tag receives response information of the target electronic price tag within second preset time, the relay price tag forwards the response information to the base station; and finally, the base station receives the response information, so that when the base station fails to establish communication connection with at least one target electronic price tag for M times within a first preset time, the base station can send a communication instruction to the target electronic price tag through a relay price tag set based on a preset rule, and thus the communication connection with the target electronic price tag is established.
