Multi-base-station electronic tag system based on batch paging

Abstract

The invention relates to a multi-base-station electronic tag system based on batch paging. The multi-base-station electronic tag system can maintain large-scale updating of electronic shelf tags undera low conflict probability and is rapid, accurate and efficient in updating. Base stations can perform paging through broadcasting. After receiving the paging request of the base station, the specific electronic shelf label can send own information to the base station; and after receiving the response information of the one or the batch of electronic shelf labels, the base station allocates new connection parameters one by one and issues the new connection parameters to the corresponding electronic shelf labels, and the base station sends the service data issued by the background management device to the electronic shelf labels through the newly allocated connection parameters. The system has the advantages that 1, the system solves the problem of high communication conflict probability between a large number of electronic shelf labels and a base station through a batch-limited paging wake-up mechanism; and secondly, the system is effectively controlled to be integrally maintained under a low conflict probability by means of reducing internal communication conflicts and external conflicts.

Description

technical field [0001] The invention relates to a large-scale update of electronic shelf labels that can not only maintain a low conflict probability, but also update quickly, accurately, and efficiently. At the same time, the system layout is simplified, and the maintenance frequency of electronic shelf labels is low. A paging multi-base station electronic label system belongs to the technical field of electronic shelf labels. Background technique [0002] Electronic shelf label is a product that has emerged in recent years. It replaces the traditional paper shelf label, making the modification of the label content faster and more accurate, saving a lot of labor costs, and more environmentally friendly. In order to facilitate system erection and wiring, the electronic shelf label system generally adopts wireless communication, which improves the convenience of the actual application of the entire system. However, in supermarkets and other occasions where electronic shelf l...

AI Technical Summary

Problems solved by technology

Although this electronic shelf label system based on multi-radio frequency base stations can meet the occasions where electronic shelf labels are used intensively in large quantities such as supermarkets (it realizes large-scale electronic shelf label management by increasing the number of radio frequency modules in the relay station), its shortcomings First, the problem of communication collision between the electronic goods price tag and the base station still exists (in the traditional way, the tag randomly initiates a heartbeat signal to the base station or wakes up the base station at regular intervals. The probability of collision of the communication signal in this way varies with The number of tags needs to increase linearly. When the number of tags and base stations is relatively large, communication conflicts are more frequent, which will seriously affect the use of the system); second, the increase in the number of radio frequency modules not only increases the production cost of the system, but also increases the cost of the system. Increasing the energy consumption of the system will also increase the volume of the relay station; the third is that the layout of the base station in the system is relatively unreasonable, which makes the energy consumption of the electronic shelf label relatively large, thereby increasing the maintenance frequency of the electronic shelf label
