Embodiment Construction

[0031] The following is further described in detail through specific implementation methods:

[0032] Such as figure 1 As shown, this embodiment discloses a synchronization method for electronic price tags, including the following:

[0033] The networking step is to allocate the wake-up time zone and the ID information corresponding to the flag for the newly connected price tags; the networking steps specifically include:

[0034] Receive the association request information sent by the price tag;

[0035] Send the association response information to the price tag, the association response information includes the update broadcast broadcast channel, the clock synchronization signal, the assigned time zone, and the assigned ID information.

[0036] In the update broadcasting step, an update broadcast is generated and broadcasted according to the current time zone information and the acquired update information; in each time zone, the gateway executes the update broadcast step ...

Abstract

The invention relates to the technical field of Internet of Things price tags, in particular to a synchronization method for an electronic price tag, which comprises the following contents of: a networking step: allocating an awakening time zone and ID information corresponding to a flag bit to a newly accessed price tag; an update broadcast step: generating an update broadcast according to the current time zone information and the acquired update information, and broadcasting the update broadcast; wherein the update broadcast comprises update state data, and the update state data comprises information about whether each price tag awakened in the current time zone needs to be updated or not. Wherein the update state data comprises a plurality of flag bits in one-to-one correspondence withthe ID information of the waken price tag in the current time zone, and the value of each flag bit indicates whether the content of the price tag corresponding to the flag bit needs to be updated or not. The synchronization method for the electronic price tags can solve the problems that in an existing electronic price tag system, the number of the price tags managed by the same gateway is limited, and the synchronous updating process of the price tags is high in power consumption.

Description

technical field [0001] This application relates to the technical field of Internet of Things price tags, specifically a synchronization 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] In the current solution, when upda...
