Electronic shelf label system communication method

Abstract

The present invention discloses an electronic shelf label system communication method. The method comprises: S1: a server sends data information to at least one wireless reader, wherein the data information comprises electronic label information; S2: each wireless reader transmits the electronic label information to electronic shelf labels; S3: each electronic shelf label returns confirmation signals of receiving the electronic label information back to the corresponding wireless reader; and S4: the at least one wireless reader sends the confirmation signals returned by the electronic shelf labels to the server, wherein the step S1 and / or the step S2 and / or the step S3 and / or the step 4 employ Sub-GHz communication frequency ranges for communication. The problem is solved that signal rectilinear propagation and communication performances are not good in an infrared communication method; the employed Sub-GHz communication frequency ranges have lower power consumption than 2.4G communication frequency ranges; and the electronic shelf label system communication method has higher communication speed advantage than a low-frequency wireless radio wave method. The electronic shelf label system communication method can an electronic shelf label system with low power consumption and high-speed communication.

Description

technical field [0001] The present invention relates to the technical field of electronic shelf labels, in particular to a communication method for an electronic shelf label system, which belongs to the technical field of the wireless Internet of Things and is applied to industries such as supermarket retailing, warehousing and logistics, and intelligent manufacturing. Background technique [0002] For a long time, the traditional retail industry has used paper price tags to display commodity prices. With the development of the retail industry, the variety of goods is increasing, and a large number of price changes caused by frequent various promotional activities are generally used to manually modify the price tag. However, manual modification has a certain time delay and error rate. The shortcomings of paper price tags in these aspects are highlighted. [0003] In order to solve the above problems, some wireless electronic shelf label systems have emerged, usually using i...
