1. A shelf label system, comprising:
one or more base stations;
at least one server that communicates with the one or more base station and is configured to:
obtain a target network topological structure according to a master base station having a shallowest topological depth and a ranging result between a base station and a superior base station of the base station, wherein each base station in the target network topological structure has a single superior base station;
generate a transceiving time slot periodic table by allocating a transceiving time slot to each base station according to the target network topological structure; and
obtain a synchronous network of the shelf label system by instructing the one or more base stations to transmit and receive synchronous signals according to the transceiving time slot periodic table; and
one or more electronic shelf labels that receive the synchronous signals from the one or more base stations.
