  • Patent number: 12317209
    Abstract: The present disclosure provides a communication method of an electronic shelf label system, a system, a computer device and a storage medium. The method includes: configuring, by a server, an offset of each of base stations in a corresponding synchronization sub-network based on neighboring relationships between all the base stations in each of the synchronization sub-networks, so that each of the base stations calculates synchronization frame transmission time in a predetermined signal transmission cycle based on the offset; calculating, by each of the base stations, idle time in a synchronization channel based on the synchronization frame transmission time, so that each of the base stations receives a target synchronization frame sent by a superior base station in the idle time of the synchronization channel. According to the present disclosure, the synchronization frames sent by all the base stations has central and adjacent feature in time.

  • Publication number: 20250056447
    Abstract: The present disclosure provides a communication method of an electronic shelf label system, a system, and a computer device. The method includes: repeatedly sending, by each of the plurality of base stations, a synchronization frame, wherein the synchronization frame includes a packet sequence number, and each of the synchronization frames includes a different packet sequence number; receiving, by the electronic shelf label, the synchronization frame at a receiving time point scheduled to wake up; determining whether the packet sequence number of the synchronization frame is the same as a packet sequence number corresponding to the receiving time point; and adjusting, if both are the same, by the electronic shelf label, a duration of the next sleep to compensate for the time difference, so as the next reception of a synchronization frame includes a packet sequence number corresponding to the receiving time point.

  • Publication number: 20250045128
    Abstract: A shelf label communication method based on a synchronous network, a shelf label system and a computer device are provided. The synchronous network includes a base station topological structure, including a master base station, a first-level secondary base station directly connected to the master base station, and a (i+1)th-level secondary base station directly connected to an ith-level secondary base station, and each base station being connected to only one superior base station. The first-level secondary base station obtains a first synchronization signal from the master base station, so the first-level secondary base station starts to operate according to system time of the master base station. Further, the (i+1)th-level secondary base station obtains a second synchronization signal from the ith-level secondary base station, so that the (i+1)th-level secondary base station starts to operate according to local system time of the ith-level secondary base station.

  • Patent number: 12153969
    Abstract: The disclosure provides a shelf label communication method based on a synchronous network, a shelf label system and a computer device. In the method, an electronic shelf label establishes a first timing task of a timer when receiving a timing service instruction; determines a timing duration of the first timing task based on a time difference between current local system time when the timing service instruction is received and the instruction execution system time, and starts the first timing task; the electronic shelf label cyclically calibrates a current timing duration in the first timing task based on the periodically received base-station system time, to obtain the calibrated current timing duration.
