Method and system for automatically upgrading electronic tag, and electronic tag

Abstract

The invention belongs to the technical field of electronic tags, and discloses an electronic tag automatic upgrading method and system, and an electronic tag, and the method comprises the steps: starting an automatic grouping mode when each electronic tag receives an upgrading preparation broadcast, and enabling each electronic tag and other associated electronic tags to form a tag group; therefore, a plurality of electronic tags can be dynamically and automatically grouped before upgrading, and then the electronic tags carry out data transmission complementation with the corresponding parent devices or child devices in the tag groups according to partial or all upgrading data received by the electronic tags, so that data mutual communication in each tag group is ensured, parallel upgrading is realized, and the upgrading efficiency is improved. The upgrading time can be effectively shortened, and the batch upgrading efficiency is improved. In addition, the success rate of batch upgrading can be improved.

Description

technical field [0001] The invention belongs to the technical field of electronic labels, and in particular relates to an automatic upgrade method and system of electronic labels, and electronic labels. Background technique [0002] In the market, wireless electronic tags with 2.4G communication capability are usually used to mark goods. There are often a large number of scattered shelves in the warehouse, and a large number of electronic tags are scattered on each shelf. [0003] Because 2.4G wireless communication is limited by factors such as transmission power and obstacles in space, the distance that can effectively transmit a large amount of data is limited. When the firmware programs in these electronic tags need to be upgraded in batches, the electronic tags to be upgraded need to be Collect them centrally, use a host computer terminal, upgrade the firmware content through 2.4G wireless broadcast, and wait for the electronic label to be upgraded. If any tags are not...

AI Technical Summary

Problems solved by technology

It can save manpower, but it needs to arrange multiple host computer terminals and connect to the network to communicate with the server, which requires a lot of hardware costs

[0005] More importantly, regardless of setting up one host computer terminal or multiple host computer terminals, there are situations where the host computer terminal needs to repeatedly broadcast redundant content. time consuming

The reason is that there is a lot of interference in the 2.4G channel, which can easily cause data transmission errors

However, the host computer terminal uses a one-to-many method to send upgrade data, and it is impossible to determine the firmware content that each electronic label has successfully received. It can only send the complete firmware program repeatedly, which will inevitably cause redundancy of sent data and reduce the upgrade efficiency.
