摘要： An electronic shelf label communication system and method. The system includes a processor, a plurality of wireless access points and an electronic shelf label. The electronic shelf label is configured to actively send a heartbeat data package to the plurality of wireless access points after periodically waking up. Each of the plurality of wireless access points is configured to: receive the heartbeat data package of the electronic shelf label, obtain signal strength data when the heartbeat data package of the electronic shelf label is received, and send the signal strength data to the processor. The processor is configured to: receive the signal strength data corresponding to the heartbeat data package sent by the plurality of wireless access points, and determine an optimal wireless access point corresponding to the electronic shelf label according to the signal strength data.

摘要： The present invention provides an electronic shelf label communication system, method and apparatus. The system comprises: a processor configured to send update data to a wireless access point corresponding to an electronic shelf label group where an electronic shelf label requiring data update is located; the wireless access point configured to send a group wakeup message to the electronic shelf label requiring data update, and send, after the electronic shelf label requiring data update wakes up according to each of countdown durations for receiving the update data, the unsent update data packages corresponding to the electronic shelf label to electronic shelf labels requiring data update in a same electronic shelf label group simultaneously, until all of the update data packages corresponding to the electronic shelf label are sent; and the electronic shelf label configured to wake up periodically, receive the group wakeup message and obtain the plurality of countdown durations for receiving the update data, and wake up again according to each of the countdown durations for receiving the update data, and receive the unreceived update data packages once, until all of the update data packages are received. The present invention has high efficiency and low power consumption.
