[0005] With the increasingly wide application of electronic price tag systems in various retail fields, electronic price tags carry the display of important information such as product name and product price. If the display of such information fails, it may have a significant impact on store operations.

[0006] The current electronic price tag system feeds back to the user whether the update price tag display instruction is issued and whether the execution result is successful according to the update price tag display instruction issued each time by the background server. The user finds the failed price tag according to the feedback result, reissues the update instruction, and if the reissue still fails, it proves that the price tag is damaged and is replaced with a new price tag. The update instruction is reissued until the display is successful.

[0007] The prior art needs to manually find the result of the issuance and execution of each update task and find the price tag that may have display abnormalities for targeted investigation and processing. This process requires the user to access the update result feedback by the background system, and the user needs to spend a lot of time and effort to find the price tag in a large store. The processing speed is slow and the work efficiency is low. In addition, the price tag display and the product information of the customer checkout system caused by the display abnormality of the price tag, especially the price, are inconsistent, which may cause the product information and the actual checkout information to be inconsistent when the customer purchases the product, thereby reducing the customer experience.

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, further detailed description of the embodiments of the present application will be given below in conjunction with the drawings. Herein, the illustrative embodiments of the present application and the description thereof are used to explain the present application, but not as a limitation of the present application.

[0031] Fig. 1 is a schematic diagram of a system for displaying a warning of an electronic price tag in the embodiments of the present application, comprising a background server 101, at least one base station 102 and a plurality of electronic price tags 103 within the signal coverage range of each base station, wherein,

[0032] The background server is configured to:

[0033] receive the product data sent by the client system; when the current background server retransmission number has not reached the maximum background server retransmission number, issue an update task to the electronic price tag through the base station according to the product data, until an update success message sent by the base station is received;

[0034] The base station is configured to:

[0035] receive the update task, and when the current base station retransmission number has not reached the maximum base station retransmission number, issue the update task to the electronic price tag, until an update success message sent by the electronic price tag is received;

[0036] The electronic price tag is configured to:

[0037] after receiving the update task, obtain the product data in the update task, start a corresponding type of timeout protection after any step of processing the product data fails, and display a warning icon of an abnormal display of the electronic price tag on the screen when the timing duration of each type of timeout protection is reached.

[0038] Compared with the technical solution in the prior art which needs to manually find the result of the issuance and execution of each update task and find the price tag that may have a display abnormality for targeted troubleshooting, the embodiments of the present application warn by displaying a display icon that may have an abnormality on the screen of the price tag to inform the clerk that the display of the price tag may have a problem, so that the clerk can initiate a re-push update instruction to the background system or reissue an update instruction after replacing the price tag when seeing the icon warning during the inspection, and timely solve the problem caused by the abnormal display of the price tag.

[0039] Fig. 2 is a detailed flowchart of the process of displaying a warning of an electronic price tag in the embodiments of the present application.

[0040] In an embodiment, the background server is configured to:

[0041] receiving the commodity data sent by the client system; clearing the retransmission number of the background server, issuing an update task to the electronic price tag through the base station according to the commodity data, adding 1 to the current retransmission number of the background server; after receiving the update failure sent by the base station, if the current retransmission number of the background server does not reach the maximum retransmission number of the background server, retransmitting the update task; if the current retransmission number of the background server reaches the maximum retransmission number of the background server, sending the update failure to the client system;

[0042] The base station is used for:

[0043] After receiving the update task, clearing the retransmission number of the base station, issuing the update task to the electronic price tag, and adding 1 to the current retransmission number of the base station; after receiving the update failure sent by the electronic price tag, if the current retransmission number of the base station does not reach the maximum retransmission number of the base station, retransmitting the update task, and if the current retransmission number of the base station reaches the maximum retransmission number of the base station, sending the update failure to the background server.

[0044] The step of processing the commodity data includes data verification, data processing, and data display;

[0045] In an embodiment, the electronic price tag is specifically used for:

[0046] Verifying the commodity data;

[0047] When the data verification is passed, if the first timeout protection has been started, closing the first timeout protection, and simultaneously processing the commodity data; the timing duration of the first timeout protection is a first duration;

[0048] When the data verification fails, feeding back error packet information to the base station, and simultaneously starting the first timeout protection;

[0049] When the data processing fails, sending the update failure as an update result to the background server, and simultaneously starting the second timeout protection; the timing duration of the second timeout protection is a second duration;

[0050] When the data processing succeeds, if the second timeout protection has been started, closing the second timeout protection, and simultaneously displaying the commodity data;

[0051] When the data display fails, sending the update failure as an update result to the background server, and simultaneously starting the third timeout protection; the timing duration of the third timeout protection is a third duration;

[0052] When the data display succeeds, if the third timeout protection has been started, closing the third timeout protection, and sending an update success message to the background server through the base station;

[0053] The base station is specifically configured to: when receiving the error packet information and the current base station retransmission number does not reach the maximum base station retransmission number, issuing an update task to the electronic price tag, and adding 1 to the current base station retransmission number.

[0054] Further, when receiving the error packet information and the current base station retransmission number reaches the maximum base station retransmission number, sending an update failure information to the background server. After receiving the update failure information sent by the base station, if the current background server retransmission number does not reach the maximum background server retransmission number, the background server issues an instruction to retransmit the update task to the base station, so that the base station retransmits the update task.

[0055] In the above embodiment, the data verification includes format, quantity, data correctness verification, etc., and the data processing includes decompression, integrity check, etc. It should be noted that whether the first timeout protection is started means whether the timing (or first timeout protection timing duration countdown) of the first timeout protection is currently started. If the timing (or countdown) is started, it is determined that the first timeout protection has been started. Whether the second timeout protection is started means whether the timing (or second timeout protection timing duration countdown) of the second timeout protection is currently started. If the timing (or countdown) is started, it is determined that the second timeout protection has been started. Whether the third timeout protection is started means whether the timing (or third timeout protection timing duration countdown) of the third timeout protection is currently started. If the timing (or countdown) is started, it is determined that the third timeout protection has been started. After the timing duration of the first timeout protection, the second timeout protection and the third timeout protection, the warning icon of the electronic price tag display abnormality is displayed on the screen. Specifically, after the timing duration of any one of the first timeout protection, the second timeout protection and the third timeout protection, the warning icon of the electronic price tag display abnormality is displayed on the screen. More specifically, when the timing duration countdown of any one of the first timeout protection, the second timeout protection and the third timeout protection is 0, the warning icon of the electronic price tag display abnormality is displayed on the screen. When the electronic price tag fails to update, it sends an update failure message to the base station, and the base station sends an update failure message to the background server. When the electronic price tag successfully updates, it sends an update success message to the base station, and the base station sends an update success message to the background server. After receiving the update failure information sent by the base station, if the current background server retransmission number does not reach the maximum background server retransmission number, the background server issues an instruction to retransmit the update task to the base station, so that the base station retransmits the update task.

[0056] The electronic price tag can discover that the price tag display may be abnormal by receiving the update task failure issued by the background server. However, there are some scenarios in which the electronic price tag and the background server expect the price tag display to be inconsistent, such as the price tag being offline due to a fault or being out of the base station signal coverage range. In this case, the price tag can also detect the price tag out-of-sync (i.e., the price tag cannot receive the synchronization signal sent by the base station at a fixed period) by an automatic method. For example, if the price tag is in an out-of-sync state for a certain threshold time, a pre-warning icon of the price tag offline is displayed on the screen.

[0057] Referring to FIG. 3, a flowchart of the electronic price tag displaying an offline abnormality pre-warning in the embodiment of the present application is shown.

[0058] In an embodiment, the electronic price tag is also used for:

[0059] After synchronization to the base station, entering a synchronization state, configuring a synchronization flag, and clearing the out-of-sync number;

[0060] After periodic wake-up, receiving the synchronization signal and judging whether the synchronization signal sent by the base station can be correctly received;

[0061] If the synchronization signal sent by the base station can be correctly received, the local time is calibrated according to the time deviation between the synchronization signal and the local time, and the next periodic wake-up is waited for;

[0062] If the synchronization signal sent by the base station cannot be correctly received, the current out-of-sync number is increased by 1; and whether the current out-of-sync number reaches a maximum out-of-sync number is judged;

[0063] If the current out-of-sync number reaches the maximum out-of-sync number, a failure state is entered, the synchronization flag is cleared, and a pre-warning icon of the electronic price tag offline abnormality is displayed on the screen;

[0064] If the current out-of-sync number does not reach the maximum out-of-sync number, the synchronization signal is continuously received.

[0065] In the above embodiment, the electronic price tag is in an out-of-sync state by default after factory shipment. After entering the store, the electronic price tag selects an optimal base station for synchronization.

[0066] Referring to FIG. 4, in an embodiment, the electronic price tag is also used for:

[0067] Periodically collecting the environmental temperature or collecting the environmental temperature when there is an update service;

[0068] Judging whether the collected environmental temperature is within the temperature range corresponding to the burning type of the electronic price tag;

[0069] If not, a pre-warning icon of the electronic price tag displaying temperature abnormality is displayed on the screen;

[0070] If yes, the environmental temperature is continuously collected.

[0071] In the above embodiment, the electronic price tag is burned with the price tag type when it leaves the factory, including frozen price tags and normal temperature price tags, each type of price tag corresponds to a temperature range, as long as the electronic price tag is in the corresponding temperature range, it is safe.
