Description

AI ESL system and its operating method {ESL SYSTEM AND OPERATING METHOD THEREOF}

The present invention relates to an AI ESL system and a method of operating the same. It provides an AI ESL system and a method of operating the same that can minimize radio interference and physical mesh network connections between ELS tags.

Conventional distribution stores use paper-type labels that display product information and prices to display and sell multiple products on shelves. However, attaching paper labels to hundreds to tens of thousands of product items was unreasonable as it required a lot of time and manpower to manage and maintain them.

Accordingly, the ESL (Electronic Shelf Label) system has recently been developed and used to provide product information and prices using electronic tags instead of paper labels.

Recently used ESL systems use wireless ESL tags to display product-related information. However, when there are a large number of product items, there is a disadvantage that network traffic increases rapidly when communicating with wireless ESL tags.

Of course, it is not limited to this, and it is effective for a plurality of wired ESL tags 1320 to be grouped into a plurality of groups, and each group of wired ESL tags to be serially connected to the wired and wireless router 1310. Through this, packet signals can be delivered simultaneously to multiple grouped wired ESL tag groups and sequentially delivered to wired ESL tags within the group. Because a large number of wired ESL tags are located within one wired tag group, there is an issue that the load on the router increases when they are all connected to the wired and wireless router 1310 at the same time. Therefore, to improve transmission speed and safety, it is effective to group 2 to 30 wired ESL tags into one group and connect them in series. Preferably, multiple lines are located on one shelf, and it is desirable to group each line into one group. Therefore, it is desirable to group 5 to 20 wired ESL tags in one group.
