1. A shelf label communication method based on a synchronous network, comprising:
establishing, by an electronic shelf label, a first timing task of a timer in response to receiving a timing service instruction sent by a server through a base station in a synchronous network, wherein the timing service instruction comprises an ID identifier of at least one electronic shelf label, a service instruction type, a configuration parameter and an instruction execution system time;
determining, by the electronic shelf label, a timing duration of the first timing task based on a time difference between a first current local system time when the timing service instruction is received and the instruction execution system time, and starting, by the electronic shelf label, the first timing task;
cyclically calibrating, by the electronic shelf label and in response to periodically receiving a synchronization signal comprising base-station system time that is sent by the base station, a second current local system time when the synchronization signal is received and a current timing duration of the first timing task based on the base-station system time, to obtain a calibrated current timing duration; and
executing, by the electronic shelf label, the timing service instruction based on the service instruction type and the configuration parameter in response to determining that the current timekeeping duration of the first timing task is equal to the calibrated current timing duration.
