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, there will be problems of slow networking speed and high power consumption, and it is difficult to meet the needs of mainstream manufacturers and customers. Customer specific parameter requirements

Embodiment 1

[0043] Such as figure 1 and figure 2 As shown, the communication method for electronic price tags in this embodiment is based on the following electronic price tag communication system, which includes electronic price tags and gateway devices.

[0044] 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 ...

Embodiment 2

[0083] The difference between this embodiment and Embodiment 1 is that in this embodiment, S500 includes:

[0084] S510: After the electronic price tag wakes up, it sends broadcast information to notify the gateway device;

[0085] S520: After receiving the broadcast information of the electronic price tag, the gateway device judges whether the electronic price tag needs to be updated, if yes, execute S530, otherwise execute S540;

[0086] S530: The gateway device establishes a connection with the electronic price tag, sends update content to the electronic price tag, and the electronic price tag updates the display content according to the updated content;

[0087] S540: The gateway device synchronizes the time zone with the electronic price tag and allocates its next wake-up time;

[0088] S550: The electronic price tag enters a dormant state. The electronic price tag actively sends broadcast information after waking up, and the gateway device uniformly judges whether ther...

Embodiment 3

[0090] The difference between this embodiment and Embodiment 1 is that, in S500 of this embodiment, the gateway device sends broadcast content on multiple channels at the same time.

Abstract

The invention relates to the technical field of electronic shelf labels, in particular to a communication method for electronic shelf labels. The communication method includes a networking step whichincludes steps executed by an electronic shelf label and steps executed by a gateway device. The steps executed by an electronic shelf label include: S110, the electronic shelf label wakes itself up at a random time in the current time zone and broadcasts networking information; S120, the electronic shelf label listens to a gateway, S130 is executed if the electronic shelf label receives time zonesetting information sent by the gateway device, otherwise, S140 is executed; S130, the electronic shelf label stops broadcasting, sets its own time zone according to the time zone setting information, and then goes into a sleep state; and S140, the electronic shelf label goes into a sleep state, and executes S110 in the next time zone. The steps executed by the gateway device include: S210, the gateway device listens to and receives networking information sent by the electronic shelf label; and S240, the gateway device sends time zone setting information to the electronic shelf label. The communication method for electronic shelf labels of the invention can reduce the power consumption of electronic shelf labels and improve the networking efficiency.

Description

technical field [0001] The invention relates to the technical field of electronic price tags, in particular to a communication method for electronic price tags. 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 demand, the...
