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.

Abstract: Methods, systems and computer devices are provided for adjusting a frame-listening cycle. The method includes: configuring, by a server, a fixed frame-listening cycle of an electronic shelf label according to a time period; and sending, by the server, a second frame-listening cycle modification command through a base station when the server is to issue the fast response service during the low power consumption time period, so that the electronic shelf label modifies the current frame-listening cycle to a fast frame-listening cycle according to the second frame-listening cycle modification command. According to the present disclosure, the electronic shelf label can not only respond to the fast response service in real time, but also keep the low power consumption of a long frame-listening cycle, thereby simultaneously satisfying the requirements of high real-time performance and low power consumption of the electronic shelf label.
