Abstract
Description
Technical Field
[0001] The present invention mainly relates to the technical field of wireless communication, and in particular, to an electronic price tag registration adaptation method, device, and electronic device. Background Art
[0002] In places such as shopping malls and stores, traditional commodity price displays use paper price tags. If a merchant wants to modify the selling price of a commodity, not only does he need to manually find the corresponding paper price tag of the commodity and replace it manually, but also needs to update the price of the commodity in the cash register system at the same time to keep the price displayed on the price tag consistent with the price in the cash register system. If the price of a commodity changes frequently or there are many commodities whose prices need to be changed, the price change operation of paper price tags is time-consuming and laborious and prone to errors.
[0003] An electronic shelf label (ESL) overcomes the above deficiencies of paper price tags. It is an electronic display device with information sending and receiving functions and can replace traditional paper price tags. For example, when a price change is needed, it only needs to be modified in the background cash register system or the price displayed on the electronic price tag can be modified in real time through a smart handheld terminal, saving a large amount of labor costs and management costs.
[0004] After the electronic price tag is registered to the base station, due to possible changes in the surrounding environment of the electronic price tag or the base station, or changes in the states of the electronic price tag and the base station itself, during the use of the electronic price tag system, the strength of the connection signal between the electronic price tag and the base station will continuously change. However, the existing electronic price tag systems do not adopt targeted solutions for the existing changes. Therefore, during the use of the electronic price tag, the response speed of the electronic price tag varies greatly, and even the electronic price tag does not respond. The electronic price tag and the base station cannot be adaptively adjusted, that is, the transmission signal strength of the electronic price tag and the transmission signal strength of the base station cannot be automatically adjusted according to the actual situation during the use of the electronic price tag system, so that the electronic price tag cannot be connected (or registered) to the optimal base station, or the transmission signal strength cannot be dynamically adjusted after connection, affecting the communication stability of the electronic price tag system. Summary of the Invention

[0038] Embodiment 1
[0039] Figure 1 is an overall schematic diagram of the communication interaction relationship between the electronic price tag and the base station in the present invention. Figure 2 is a flowchart of an adaptive method for electronic price tag registration in an embodiment of the present invention. Refer to Figure 1 and Figure 2 , the method 200 is applied to the electronic price tag side and includes:
[0040] S210. When the electronic price tag is in the registration state, scan and obtain the transmission signal strength of the base stations in the environment; wherein the base stations include registered base stations, and the registered base station is the base station that the electronic price tag has currently successfully registered with.
[0041] After the electronic price tag is registered, a communication connection relationship can be established between it and the base station. With the long-term use of the electronic price tag system, changes in either the electronic price tag and the base station itself or the surrounding environment may cause changes in the communication signal between the electronic price tag and the base station. Therefore, it is necessary to pay attention to such changes in order to take corresponding measures. The most direct manifestation of the above changes is the transmission signal strength of the base station. Therefore, it is necessary to obtain the transmission signal strength of the base station so as to understand the strength of the transmission signal of the base station during the use of the electronic price tag system. In this embodiment, the electronic price tag periodically scans to obtain the broadcast signals of the base stations in the environment, where the base stations include registered base stations and other base stations, and the registered base station is the base station that the electronic price tag has currently successfully registered with. After the electronic price tag scans the broadcast signal of the base station, it can obtain the transmission signal strength of the base station.
[0042] For example, the electronic price tag can periodically scan the broadcast signal of the base station (once every 15 / 60 seconds) and record the broadcast signal strength of the base station in the current environment. The electronic price tag 1.0 and the electronic price tag 2.0 can record up to 32 and 8 base station broadcast signals respectively. The power of the signal sent by the electronic price tag is generally -10.5dBm to 2.5dBm, and the default is 0dbm. Its received signal sensitivity is -85dbm. Generally, the default power of the signal sent by the base station is 7.5dBm, and the received signal sensitivity is -93dbm.
[0043] S220. If the transmission signal strength of the registered base station is less than the first threshold and lasts for a period of time, and the electronic price tag does not scan the optimal base station, then report the information that the transmission signal strength of the registered base station is less than the first threshold to the registered base station; where the optimal base station is the base station with the strongest transmission signal strength, and the information reported by the electronic price tag is used for the registered base station to determine whether to adjust the transmission signal strength of the registered base station.
[0044] In this embodiment, if the transmission signal strength of the registered base station obtained by the electronic price tag is less than the first threshold, and the first threshold is a reference value set according to the actual situation, it indicates that the transmission signal strength of the registered base station is weak at this time, and the communication between the electronic price tag and the registered base station is weak and unstable. Since the electronic price tag periodically scans to obtain the broadcast signals of the base stations in the environment, the electronic price tag can compare the broadcast signals of the base stations it scans to obtain the optimal base station, and the optimal base station is the base station with the strongest transmission signal strength and can last for a period of time.
[0045] The optimal base station is one of all the base stations. The requirement that the optimal base station needs to have the strongest transmission signal strength and last for a period of time is to avoid the situation where the judgment of the optimal base station is distorted, that is, the situation where the instantaneous transmission signal strength of a certain base station is strong. If the electronic price tag does not scan the optimal base station, it indicates that the transmission signal strength of the registered base station currently connected to the electronic price tag is the strongest (compared with other base stations). Therefore, the electronic price tag cannot maintain good communication by changing the registered base station. When the electronic price tag does not scan the optimal base station, report the information that the transmission signal strength of the registered base station is less than the first threshold, that is, the signal that the transmission signal strength of the registered base station is weak, to the registered base station, which is used for the registered base station to decide what adjustment method to take to strengthen the communication signal strength between the electronic price tag and the base station. For example, when the electronic price tag is registered or the registered base station is the optimal base station, if the electronic price tag receives the transmission signal strength of the registered base station lower than -85dbm, the electronic price tag will actively report the information that the transmission signal strength of the registered base station is weak to the registered base station.
[0046] In some embodiments, if no broadcast signal of any base station is scanned for a continuous period of time, the electronic price tag is restored to the unregistered state so that the electronic price tag can be re-registered according to subsequent new conditions. For example, the connection scanning time of the electronic price tag is set to 8 minutes. If the electronic price tag cannot scan any broadcast signal of the base station for 8 consecutive minutes, the electronic price tag is restored to the unregistered state.
[0047] In some embodiments, the status parameters of the electronic price tag are reported to the registered base station, where the status parameters include the transmission signal strength of the registered base station, the transmission signal strength of the electronic price tag, and the battery power of the electronic price tag. Since the subsequent registered base station needs to determine whether to adjust its transmission signal strength, the electronic price tag can report its status parameters to the registered base station regularly or according to the actual situation, so that the registered base station can make corresponding judgments and adjustments.
[0048] In some embodiments, when the transmission signal strength of the registered base station is less than the first threshold and lasts for a period of time, if the electronic price tag scans the optimal base station, the optimal base station is selected as the registered base station of the electronic price tag, that is, the electronic price tag can maintain good communication by changing the registered base station. The relationship between the electronic price tag and the base station is many-to-one. An electronic price tag can only be connected to one base station, and one base station can be connected to thousands of electronic price tags (not simultaneously). Generally, a store or shop has two base stations and nearly two thousand electronic price tags. Multiple base stations send broadcasts, and a single electronic price tag is scanned passively. The electronic price tag actively registers to the base station with the strongest transmission signal strength. When the base station connected by the electronic price tag is offline or the transmission signal strength is lower than that of other base stations for a continuous period of time, the electronic price tag actively migrates to the base station with a stronger transmission signal strength. For example, if the electronic price tag is already registered and the transmission signal strength of the current registered base station is less than 5 dB of other base stations scanned and statistically analyzed for 5 consecutive minutes, the electronic price tag actively migrates to the base station with a stronger transmission signal strength. After the migration is successful, the base station with a stronger transmission signal strength synchronizes the information to the original registered base station.
[0049] In some embodiments, if the transmission signal strength of the registered base station is greater than the second threshold, the transmission signal strength of the electronic price tag is reduced with reference to the ratio of the transmission signal strength of the registered base station to its rated signal strength (the maximum signal transmission strength of the base station) to save the power consumption of the electronic price tag, where the second threshold is greater than the first threshold. In this embodiment, if the transmission signal strength of the registered base station is greater than the second threshold, it indicates that the transmission signal strength of the registered base station is strong at this time. Therefore, the transmission signal strength of the electronic price tag can be adjusted downward according to the ratio of the transmission signal strength of the registered base station to its rated signal strength, so as to save the power consumption of the electronic price tag while maintaining stable communication.
[0050] The electronic price tag registration adaptation method provided in this embodiment enables the electronic price tag to report information that the signal strength of the registration base station it sends is less than the first threshold. Consequently, the registration base station can dynamically adjust the signal strength of the registration base station based on the above information, making the communication between the electronic price tag and the registration base station more stable.
[0051] Embodiment 2
[0052] Figure 1 is an overall schematic diagram of the communication interaction relationship between the electronic price tag and the base station in the present invention. Figure 3 is a flowchart of the electronic price tag registration adaptation method in another embodiment of the present invention. Refer to Figure 1 and Figure 3 , the method 300 is applied to the electronic price tag side and includes:
[0053] S310. Scan the broadcast signals of the base stations in the environment to obtain the current signal strength and rated signal strength of each base station.
[0054] When the electronic price tag is not registered, the electronic price tag can scan the broadcast signals of each existing base station in the environment, and then obtain the signal strength and rated signal strength of each base station. By comparing the signals of each base station, the optimal base station can be obtained. The optimal base station is the base station with the strongest signal strength and can last for a period of time.
[0055] In some embodiments, the electronic price tag records the signal strength and rated signal strength of each base station it scans, as well as the signal strength and rated signal strength of the electronic price tag itself, so that the electronic price tag can analyze and compare the signal strength of the corresponding base station, and then make an accurate judgment, including judging whether the base station has a fault, etc. For example, if there is a sudden change or abnormality in the signal strength of a certain base station recorded by the electronic price tag, it indicates that the base station device may have a fault, and the electronic price tag can report the relevant information to the base station or to a server such as the cloud, and the staff can check the base station device that may have a fault according to the relevant information.
[0056] S320. Send a registration request message to the optimal base station among all the base stations.
[0057] When the electronic price tag is not registered, select the optimal base station and send a registration request message to the optimal base station to complete the registration of the electronic price tag. The electronic price tag selects the optimal base station for registration, enabling the electronic price tag to have the optimal communication state at the beginning of registration.
[0058] In some embodiments, if the transmission signal strength of the optimal base station is less than the third threshold, the transmission signal strength of the electronic price tag is enhanced. In this case, although the optimal base station can be scanned among the current base stations, even so, the optimal base station still cannot well meet the communication requirements between the electronic price tag and the base station. Therefore, the transmission signal strength of the electronic price tag can be enhanced, thereby improving the success rate of electronic price tag registration and the stability of communication. For example, if the electronic price tag is registered to or about to register to the optimal base station, but the transmission signal strength of the base station received by the electronic price tag is lower than -85 dbm, the transmission signal strength of the electronic price tag can be increased by 0.5 dbm.
[0059] S210. When the electronic price tag is in the registration state, scan and obtain the transmission signal strength of the base stations in the environment; where the base stations include the registered base station, and the registered base station is the base station that the electronic price tag has currently successfully registered to. This step has been described in detail above and will not be elaborated here.
[0060] S220. If the transmission signal strength of the registered base station is less than the first threshold and lasts for a period of time, and the electronic price tag does not scan the optimal base station, then report the information that the transmission signal strength of the registered base station is less than the first threshold to the registered base station; where the optimal base station is the base station with the strongest transmission signal strength, and the information reported by the electronic price tag is used for the registered base station to determine whether to adjust the transmission signal strength of the registered base station. This step has been described in detail above and will not be elaborated here.
[0061] For the electronic price tag registration adaptive method provided in this embodiment, the electronic price tag reports the information that the transmission signal strength of the registered base station is less than the first threshold, so that the registered base station can dynamically adjust the transmission signal strength of the registered base station according to the above information, making the communication between the electronic price tag and the registered base station more stable. In addition, when the electronic price tag is registered for the first time, it selects the optimal base station for registration, so that the electronic price tag has the optimal communication state at the beginning of registration.
[0062] Embodiment III
[0063] Figure 1 is the overall schematic diagram of the communication interaction relationship between the electronic price tag and the base station in the present invention. Figure 4 is the flowchart of another embodiment of the electronic price tag registration adaptive method in the present invention. Refer to Figure 1 and Figure 4 , Method 400 is applied to the base station side and includes:
[0064] S410. When the electronic price tag is in the registration state, receive the information that the transmission signal strength of the registered base station reported by the electronic price tag is less than the first threshold; where the registered base station is the base station that the electronic price tag has currently successfully registered to.
[0065] After the electronic price tag is registered, a communication connection relationship can be established between the registration base station and the electronic price tag. With the long-term use of the electronic price tag system, changes in either the electronic price tag and the registration base station itself or the surrounding environment may cause changes in the communication signal between the electronic price tag and the registration base station. Therefore, it is necessary to pay attention to such changes in order to take corresponding measures. The most direct manifestation of the above changes is the transmission signal strength of the registration base station, and the electronic price tag needs to obtain the transmission signal strength of the registration base station and report it to the registration base station. The registration base station receives the information that the transmission signal strength of the registration base station reported by the electronic price tag is less than the first threshold, so as to understand the strength of the transmission signal strength of the registration base station.
[0066] S420. Determine whether it is necessary to adjust the transmission signal strength of the registration base station.
[0067] In this embodiment, if the transmission signal strength of the registration base station is weak, that is, the transmission signal strength of the registration base station is less than the first threshold, then increase the transmission signal strength of the registration base station. If the transmission signal strength of the registration base station meets the requirements, it indicates that there may be related problems with the electronic price tag. For example, the battery power of the electronic price tag is insufficient, the electronic price tag fails, the position of the electronic price tag is inappropriate, etc., then relevant processing needs to be carried out on the electronic price tag.
[0068] In some embodiments, determining whether it is necessary to adjust the transmission signal strength of the registration base station is judged according to all the electronic price tags currently connected to the registration base station. If the transmission signal strengths of the registration base station and all the electronic price tags are less than the first threshold, then adjust the transmission signal strength of the registration base station. Otherwise, report the information that the position of the electronic price tag needs to be adjusted. It can be understood that "all electronic price tags" in this embodiment can be understood as most electronic price tags, and only need to be able to judge whether it is a problem of the electronic price tag or the registration base station itself through the feedback of the electronic price tags connected to the registration base station. For example, when the electronic price tag is connected to the optimal base station, if the transmission signal strength of the registration base station scanned continuously for a period of time is lower than a certain reference value (such as -85dbm), the electronic price tag actively reports the information that the transmission signal strength of the registration base station is weak. The registration base station counts the reported transmission signal strengths of all the electronic price tags it connects, compares with the transmission signal strengths of other base stations in the same network, and decides whether to increase the transmission power of the registration base station, or report to a cloud server or the like that the current electronic price tags with weak transmission signal strength need to adjust their positions, etc.
[0069] In some embodiments, the status parameters reported by all the electronic price tags connected to the registered base station are statistically analyzed, and the transmission signal strength of the registered base station is adjusted. The status parameters include the transmission signal strength of the registered base station, the transmission signal strength of the electronic price tag, and the battery power of the electronic price tag, and then it is determined whether the transmission signal strength of the registered base station needs to be adjusted. For example, the registered base station obtains a signal strength curve similar to a normal distribution graph based on the signal strength of all the price tags statistically analyzed. The registered base station obtains the transmission signal strength of the networking base stations and the number of registered electronic price tags in the current environment, and then compares the transmission signal strength and the number of registered electronic price tags in the networking base stations. 1. If the transmission signal strength of the registered base station is 3 dBm higher than the average value, or the number of registered electronic price tags exceeds 3000 and is twice the average registration number, it is reported that the transmission signal strength of the electronic price tag reported to the cloud is weak, and the position of the electronic price tag needs to be adjusted; 2. Otherwise, the transmission signal strength of the registered base station is increased by 0.5 dBm, that is, the transmission signal power is increased by 12.3%, and the electronic price tag is replied with the transmission signal power (strength) of the current base station to obtain the transmission signal power of the electronic price tag; 3. According to the transmission signal strength of the electronic price tag fed back by the registered base station, if it is weaker than -80 dbm, the transmission signal strength of the electronic price tag is increased by 0.5 dBm, and if it is stronger than -65 dbm, the transmission signal strength of the electronic price tag is decreased by 0.5 dBm. In addition, if the lowest value of the transmission signal strength curve statistically analyzed by the registered base station every 30 minutes is higher than -80 dbm and the transmission signal strength of the base station is higher than the default power of the transmission signal strength, the registered base station decreases its transmission signal power by 0.5 dBm.
[0070] S430. If the transmission signal strength of the registered base station needs to be adjusted, then adjust the transmission signal strength of the registered base station.
[0071] In some embodiments, if the registered base station chooses to increase its transmission signal strength, it needs to coordinate the transmission power with the electronic price tags with weak current signals. After the increase in the transmission signal strength is successful, the registered base station synchronizes the information to other base stations in the same network. Of course, the difference in the transmission signal strength between base stations in the same environment should not be too large to avoid unbalanced load. The transmission signal strength of the registered base station cannot be blindly increased, and it needs to be adjusted according to the transmission signal strength of the statistically analyzed electronic price tags to avoid the situation where the electronic price tag can receive the broadcast signal of the base station but cannot connect to the base station.

Refer to Figure 1 and Figure 5 , the method 500 is applied to the base station side and includes:
[0075] S510: Send a broadcast signal.
[0076] The base station sends a broadcast signal so that when the electronic price tag is not registered, the electronic price tag can scan the broadcast signals of each base station existing in the environment, and then obtain the transmission signal strength and the rated signal strength of each base station. By comparing the signals of each base station, the optimal base station can be obtained. The optimal base station is the base station with the strongest transmission signal strength and can last for a period of time.
[0077] S520: After receiving the registration request information of the electronic price tag, grant the registration of the electronic price tag and record the transmission signal strength of the registered base station reported by the electronic price tag.
[0078] As the optimal base station, after receiving the registration request information of the electronic price tag, the base station grants the registration of the electronic price tag and completes the registration process of the electronic price tag. When the electronic price tag is registered for the first time, it selects the optimal base station for registration, so that the electronic price tag has the optimal communication state at the beginning of registration.
[0079] S530: Send the information that the electronic price tag registration is successful to the electronic price tag.
[0080] In this embodiment, the information that the electronic price tag registration is successful is sent to the electronic price tag. Further, after granting the registration of the electronic price tag, the current transmission signal strength and the rated signal strength of the registered base station can also be sent to the electronic price tag.
[0081] S410: When the electronic price tag is in the registered state, receive the information that the transmission signal strength of the registered base station reported by the electronic price tag is less than the first threshold; where the registered base station is the base station currently successfully registered by the electronic price tag. This step has been described in detail before and will not be repeated here.
[0082] S420: Determine whether it is necessary to adjust the transmission signal strength of the registered base station. This step has been described in detail before and will not be repeated here.
[0083] S430: If it is necessary to adjust the transmission signal strength of the registered base station, then adjust the transmission signal strength of the registered base station. This step has been described in detail before and will not be repeated here.
[0084] The electronic price tag registration adaptation method provided in this embodiment enables the registration base station to dynamically adjust the transmission signal strength of the registration base station according to the information that the transmission signal strength of the electronic price tag reported to the registration base station is less than the first threshold, making the communication between the electronic price tag and the registration base station more stable. In addition, when the electronic price tag is registered for the first time, it selects the optimal base station for registration, so that the electronic price tag has the optimal communication state at the beginning of registration.
