Synchronous network construction method, price tag system, computer equipment and storage medium

Abstract

The present invention provides a synchronization network construction method, a price tag system, computer equipment and a storage medium. The method includes: establishing an initial network topology structure of a base station; Depth traversal to obtain the topology depth corresponding to each base station; adjust the initial network topology structure according to the ranging results from each base station to the superior base station, and obtain the target network topology structure; according to the target network topology structure, assign each base station to The sending and receiving time slots are obtained from the periodic table of sending and receiving time slots to obtain the synchronization network of the price tag system. The invention solves the problem of mutual interference between multiple base stations in the electronic price tag system in the prior art when sending and receiving signals, and maintains time synchronization between multiple base stations by establishing a synchronization network, and based on the time-sharing of the synchronization network Gap to send and receive data to prevent signal interference, improve the stability and data throughput of the electronic price tag system.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method for constructing a synchronization network, a price tag system, a computer device and a storage medium. Background technique [0002] As the electronic price tag system is more and more widely used in various retail fields, and the scale of the store is also getting larger and larger, multiple base stations need to be deployed in the store, and multiple base stations communicate through asynchronous cellular networks; however, in the existing asynchronous cellular networks In the network, the sending and receiving signals of multiple base stations in the store are asynchronous, and the time slots used are prone to conflict, which may cause interference between the sending and receiving signals of multiple base stations, resulting in the communication failure between the base station and the price tag. [0003] It can be seen that there is a problem of mu...
