Problems solved by technology

Due to the characteristics of the Mesh protocol and the special requirements of the price tag on data transmission and power consumption, if the price tag is directly added to the Mesh network as a node device, network collisions are likely to occur during networking or data transmission, which will cause slow networking speed. , The problem of high power consumption, it is difficult to meet the specific parameter requirements of mainstream manufacturers and customers

Embodiment 1

[0022] Such as figure 1 As shown, the low-energy electronic price tag system in this embodiment includes an electronic price tag and a gateway device.

[0023] The electronic price tag includes a network sending module, a time zone synchronization module, a data update module and a dormancy module. The network sending module is used to use the first preset duration as a time zone, wake itself up at a random time in each time zone and broadcast the network Information; the time zone synchronization module is used to receive the time zone synchronization information sent by the gateway device and set its own time zone synchronously according to the time zone synchronization information and calculate the next wake-up time. The sleep module is used to make the electronic price tag in sleep mode, and the data update module is used for Obtain the update content from the gateway device and update the display content of the electronic price tag.

[0024] In this embodiment, when the ...

Embodiment 2

[0060] The difference between this embodiment and Embodiment 1 is that the electronic price tag includes a wake-up broadcast module, which is used to broadcast readiness information after the electronic price tag is woken up, and the gateway device includes a label update judgment module and an update transmission module. The module is used to judge whether the electronic price tag needs to be updated according to the ready information. The update transmission module is used to establish a connection with the electronic price tag after detecting that the electronic price tag needs to be updated, and send the update content to the electronic price tag; the time zone setting module is also used to When it is detected that the electronic price tag does not need to be updated, it will synchronize the time zone with the electronic price tag and assign its next wake-up time. Correspondingly, S500 of the communication method of the corresponding electronic price tag includes:

[0061...

Embodiment 3

[0067] The difference between this embodiment and Embodiment 1 is that in this embodiment, multiple data transceiver modules are set on the gateway device, and the broadcast module is updated to send broadcast content on multiple channels at the same time, so that the broadcast content can be broadcast on multiple channels at the same time. Broadcasting can further reduce the time required for the electronic price tag to receive the broadcast and reduce power consumption.

Abstract

The present invention relates to the technical field of electronic price tags, specifically a low-energy electronic price tag system, including an electronic price tag and a gateway device. The gateway device includes an update acquisition module, a listening module, and a time zone setting module. The update acquisition The module is used to obtain the update content of the electronic price tag from the server, the listening module is used to listen to and receive the networking information sent by the electronic price tag, and the time zone setting module is used to receive the information sent by the electronic price tag Send the time zone synchronization information to the electronic price tag after the networking information; the electronic price tag includes a networking sending module, a time zone synchronization module, a data update module and a sleep module, and the networking sending module is used for the A time zone, wakes itself up at a random time in each time zone and broadcasts networking information. The low-energy electronic price tag system provided by the present invention can reduce the power consumption of the electronic price tag, improve the networking efficiency, and shorten the networking time.

Description

technical field [0001] The invention relates to the technical field of electronic price tags, in particular to an electronic price tag system with low energy consumption. Background technique [0002] In recent years, the new retail format that integrates online and offline is gradually gaining widespread attention in the market. At the same time, it is also facing the problem of how to realize the connection between offline supermarkets and online e-commerce platforms, that is, how to synchronize product information changes in a timely and accurate manner. Go to different scenes online and offline. Traditional paper labels cannot do this, but electronic price tags (ESL) can update product information in a timely manner through wireless communication and synchronize to major platforms, thereby improving the efficiency of retail operations. Therefore, electronic shelf labels will become an important driving force behind new retail. [0003] However, for such a new type of d...
