Updating control method and system for electronic price tag display information

Abstract

The invention provides an updating control method and system for the electronic price tag display information, and the method comprises the steps that before the execution time reaches, an AP base station sends a commodity sales template to an electronic price tag according to the identification information in the commodity management information obtained from a server; the electronic price tag stores the received commodity sales template and compares whether the internal time of the electronic price tag reaches the execution time or not; the electronic price tag switches and displays a corresponding sales template according to a comparison result, wherein the commodity management information comprises the electronic price tag identification information of a to-be-switched template and thecommodity sales template, and the commodity sales template comprises the commodity information and the corresponding execution time. The AP base station issues the template in advance, so that the commodity template can be normally and timely switched and displayed without the participation of the AP base station when the execution time reaches, the display switching time is reduced, and in addition, a plurality of price tags are ensured to synchronously refresh the display template.

Description

technical field [0001] The invention relates to the technical field of commodity electronic price tags and communication, in particular to a method and system for updating and controlling display information of electronic price tags. Background technique [0002] The existing electronic shelf label (ESL) system includes a server, an electronic shelf label and an AP base station. The AP base station can enable the server to communicate normally with the electronic price tag without being interfered by other smart terminals such as mobile phones and computers. Electronic price tag is an electronic display device with information sending and receiving function, which is mainly used in electronic electronic price tags for displaying price information in supermarkets, convenience stores, pharmacies, etc. [0003] In the current living environment, many large shopping malls, supermarkets, convenience stores, pharmacies and other application scenarios still use paper electronic pr...

Problems solved by technology

[0004] However, in the existing technology, if the product information of a certain type of product changes, the AP base station will issue a new template to the electronic price tag only when the start time is reached. The new template includes the changed product information and the end time is reached. Then switch back to the default template, this mode will have the following disadvantages: 1. When the number of electronic price tags is large, the AP base station will not be able to issue new templates to each electronic price tag in time due to communication problems, resulting in the failure of electronic price tags in time Toggle display of new templates

2. When the number of electronic price tags is large, there will be a large switching display time no matter at the beginning or at the end

3. When the number of electronic price tags is large, if the AP base station is disconnected or malfunctions midway, it will affect the normal switching of the electronic price tags and display the new template

[0005] How to solve the above problems that cannot be displayed normally and in a timely manner, and reduce the switching display time, and cannot ensure that multiple price tags can refresh the display template synchronously is an urgent problem to be solved
