The Working Principle Of Electronic Shelf Label

When shopping in supermarkets and retail stores, it's common to see a small display next to each product that shows information about the product. These are electronic shelf labels. Electronic shelf labels are an important part of the electronic shelf label system. They are mainly used to display product and promotional information, replacing traditional paper labels.

The electronic shelf label system consists of a server, software, gateway (base station/access point) and price tag. Install the software on the server, enter the product information into the software, and send the product information in the software to the gateway (base station/access point) through the network. The gateway (base station/access point) then sends this information to the price tag. The core components of the system are the main computer and database, which store basic information and price information for all products. Install the electronic shelf label system application software on the server, and then encode and process the product information in the database. These updated information (such as prices) are transmitted to the gateway (base station/access point) via the Ethernet or serial communication port. A gateway (base station/access point) sends an RF radio signal containing product data information to a range of price tags.

Electronic shelf labels are wireless data receivers with identification codes that can receive these radio frequency signals and restore them to valid digital signals for display. The electronic shelf label system has both point-to-point and group communication functions.

The working principle of the electronic shelf label system is mainly based on wireless communication technology, which can realize real-time updating and display of commodity prices and other related information. Nowadays, electronic shelf labels are widely used in places such as supermarkets, convenience stores, fresh food supermarkets, home furnishings and daily necessities stores. These places have a wide range of products and prices change frequently. Electronic shelf labels can update price information in real time, improving the efficiency and accuracy of product management.

It is believed that with the advancement of technology, electronic shelf label systems will enter more fields. Through integration and collaboration with other systems, electronic shelf label systems can achieve more functions and improve overall operational efficiency.
