Electronic price tag, gateway and electronic price tag system

Abstract

The invention discloses an electronic price tag, a gateway and an electronic price tag system, and relates to the technical field of electronic price tag networking, and the electronic price tag comprises a data dynamic sending module which is used for randomly selecting time in a preset time interval and sending broadcast information to the gateway; the wake-up time selection module is used for entering sleep to select the wake-up time in the next time interval when the feedback information of the gateway is not obtained; and the time calculation module is used for stopping sending the broadcast information when the feedback information is obtained, entering dormancy and calculating the time for sending the data updating request information by next wake-up according to the time zone parameter information. The gateway comprises a time zone configuration module which is used for configuring a time zone and sending time zone parameter information to the electronic price tag. The electronic price tag system comprises the electronic price tag and a gateway. According to the invention, the broadcast information is sent by segmenting the electronic price tags and randomly waking up the electronic price tags within the segmentation time, so that automatic and rapid networking of the plurality of electronic price tags and the gateway is realized, and the network collision probability is reduced.

Description

technical field [0001] The invention relates to the technical field of electronic price tag networking, in particular to an electronic price tag, a gateway and an electronic price tag system. Background technique [0002] At present, in stores such as supermarkets and convenience stores, the selling price information is generally conveyed to customers through shelf labels of paper media arranged at product placement positions. In the case of shelf labels using this paper medium, because the management of shelf labels has to rely on manual labor, it is prone to the problem of untimely updates and wrong selling prices; and every time the product information changes, it must be updated. Printing or handwriting is a waste of resources and inconvenient to operate. [0003] In recent years, Electronic Shelf Label (Electronic Shelf Label) is being gradually applied. It is an electronic display device placed on a shelf that can replace traditional paper price tags. Each electronic...

Problems solved by technology

[0004] When updating the data of the electronic shelf label, the electronic shelf label generally adopts the communication method that the electronic shelf label actively queries the server for the information that needs to be updated. Since in an application system, there are countless labels whose information is being updated, their wake-up is Random and dynamic, each tag has the problem of requesting data and downloading data from the server at the same time, that is, when tags request data and download data, collisions will occur, resulting in information loss

Therefore, there is an urgent need for an electronic shelf label system that assigns a fixed time zone to it when the electronic shelf label is networked, so as to avoid the problem of mutual collision and interference when multiple electronic shelf label data are updated and broadcast.
