Embodiment Construction

[0033] Please refer to figure 1 , figure 1 A schematic diagram of an electronic shelf label system 100 according to an embodiment of the present invention is shown. The electronic shelf label system 100 includes a shelf 110 , electronic shelf labels 131 and 132 , and a radio frequency signal transceiver 120 . The electronic shelf labels 131 and 132 are arranged on the shelf 110 , and the electronic shelf labels 131 and 132 are respectively arranged with radio frequency antennas 1311 and 1321 . In addition, the radio frequency signal transceiver 120 performs data transmission and reception with the electronic price tags 131 and 132 through the radio frequency antennas 1311 and 1321 respectively. Wherein, the angle A1 between the connection line between the radio frequency signal transceiver 120 and the radio frequency antenna 1311 on the electronic price tag 131 and the extending direction HD1 of the signal emission H plane of the radio frequency antenna 1311 is smaller tha...

Abstract

An electronic shelf label (ESL) system is disclosed. The ESL system includes a shelf, at least an ESL, and a radio-frequency (RF) signal transceiver. The ESL is disposed on the shelf. The ESL includes a RF antenna, and the RF antenna defines a signal transmitting H-plane. The RF signal transceiver transceives data with the ESL through the RF antenna, wherein, a connection line between the RF signal transceiver and the RF antenna has an included angle smaller than a pre-determined angle with the signal transmitting H-plane of the RF antenna.

Description

technical field [0001] The present invention relates to an electronic shelf label system, and in particular to an electronic shelf label system for data transmission and reception through radio frequency signals. Background technique [0002] In the existing technical field, there is an application method of providing an electro-phoretic display (EPD) as an electronic shelf label (Electronic Shelf Label, ESL). Among them, on the electronic shelf label, the radio frequency signal is used to transmit data with the radio frequency signal transceiver. The shelf manager can use the set multiple radio frequency signal transceivers to perform corresponding electronic shelf label management actions. [0003] However, since there are often many different noises in the storage area of ​​the goods (such as the store), the signal and noise ratio (SNR) of the radio frequency signal for data transmission between the electronic shelf label and the radio frequency signal transceiver is low...
