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 i^th-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 i^th-level secondary base station, so that the (i+1)^th-level secondary base station starts to operate according to local system time of the i^th-level secondary base station.
