Visible light communication based intelligent electronic shelf label system and application method thereof

Abstract

The invention relates to a visible light communication based intelligent electronic shelf label system and an application method thereof. The system comprises a server, a transmitter and a receiver; the server is used for acquiring label information with label ID (identity) and sending the label information according to the label ID; the transmitter is used for receiving the label information with the label ID sent by the server after establishing communication with the server, converting the label information into a corresponding visible light signal and sending the visible light signal; the receiver is used for receiving the visible light signal sent by the transmitter, converting the visible light signal, generating to-be-displayed label information according to the label ID and displaying the to-be-displayed label information. The system has high anti-jamming capability, so that stability and reliability in information transmission are guaranteed.

Description

technical field [0001] The invention relates to an electronic shelf label system, and provides an intelligent electronic shelf label system based on visible light communication and a method for applying the intelligent electronic shelf label system based on visible light communication. Background technique [0002] At present, most shopping malls and supermarkets (hereinafter referred to as "supermarkets") still use paper shelf labels to display information related to commodities, and manage commodity information based on barcode technology and back-end servers. With the development of large-scale chain operations of supermarkets, promotional discounts and other activities are becoming more and more frequent, and product information is becoming more and more comprehensive and flexible. Paper shelf labels and their management systems highlight their disadvantages: [0003] 1) The production of paper labels needs to be completed in advance and requires a lot of printing consum...

AI Technical Summary

Problems solved by technology

For commodities with frequent price changes (such as fresh meat and vegetables), it takes a lot of printing and management costs;

[0004] 2) The placement of paper labels and subsequent maintenance and replacement require a lot of manpower and cannot be automated

In particular, large-scale supermarkets have frequent operations such as product information changes, price adjustments, and shelf relocations. Replacing and maintaining paper labels has become an extremely cumbersome task.

In addition, in the case of a large number of products, manual placement of labels is also prone to errors, resulting in reduced sales (such as placing a high-price label on a low-priced product by mistake) or transaction disputes (such as placing a low-price label on a high-priced product by mistake). commodity department), increasing the additional maintenance cost of the supermarket;

[0005] 3) The specification of the paper label depends on the label template, not only the display content is limited, but also limited by the label production cycle and cost, it is not easy to realize flexible content customization for different commodities to promote sales

However, due to serious wireless interference and radiation problems in traditional wireless communication technologies, the security, reliability and stability are poor.

The deployment and implementation of the ESL system based on traditional wireless communication technology is still relatively complicated, the signal reliability is lacking, and the cost is high, which leads to restrictions on its large-scale promotion and implementation
