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.
