Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and a system for electronic price tag communication and a computer-readable storage medium.

Background

In the electronic price tag system, in order to avoid mutual interference of transmission signals between base stations, adjacent base stations generally adopt different channels to form a structure similar to a cellular network. The price tag also can transmit signals, and the duration of the signals is longer in partial scenes; meanwhile, because the number of price tags is large, comprehensive consideration is needed when channel configuration of the base station and the price tags is carried out, and transmission signals between the base station and the base station, between the base station and the price tags and between the price tags cannot interfere with each other.

In order to solve the above problems, the transmission of signals is generally completed by manually planning and selecting different channels or adopting a simple collision avoidance waiting strategy, but the method is limited to a place with a small price tag number.
