Embodiment Construction

[0025] Such as figure 1 As shown, a passive non-contact electronic shelf label system includes a product information server 1 , a portable read-write device 2 , and a plurality of passive non-contact electronic shelf labels 3 .

[0026] The passive non-contact electronic shelf label 3 is installed on the shelf, and its structure includes: RF electromagnetic field energy collection module 3-1, dual interface communication memory 3-2, power management module 3-3, central controller 3-4 and dual Steady state display 3-5.

[0027] The RF electromagnetic field energy acquisition module 3-1 can collect the energy of the RF electromagnetic field sent by the portable read-write device 2 through the antenna and convert it into electrical energy. The carrier frequency of the RF signal ranges from low frequency 100kHz to high frequency, ultrahigh frequency and microwave 6GHz.

[0028] The dual-interface communication memory 3-2 can carry out non-contact two-way radio frequency communica...

Abstract

The invention relates to a passive non-contact type electronic goods shelf label system. An existing system is high in cost and low in efficiency. The passive non-contact type electronic goods shelf label system comprises a goods information server, a portable read-write device, and a plurality of passive non-contact type electronic goods shelf labels, wherein the passive non-contact type electronic goods shelf labels comprise a radiofrequency electromagnetic field energy harvesting module, a double-interface communication storage, a power management module, a central control unit and a bi-stable state display screen. The portable read-write device comprises a radiofrequency communication module corresponding to the radiofrequency electromagnetic field energy harvesting module and the double-interface communication storage, a communication module which communicates with the goods information server, a power module, an information input module and a display screen, the goods information server runs the goods information management system, and goods information data are stored on a hardware of the goods information server. Batteries do not need to be arranged on the electronic goods shelf labels in the passive non-contact type electronic goods shelf label system, and therefore use and maintenance costs are reduced, update can be conducted without a cable contact method due to using a non-contact method, and the update is convenient and high-efficiency.

Description

technical field [0001] The invention belongs to the technical field of RFID radio frequency identification, relates to an electronic shelf label, in particular to a passive non-contact electronic shelf label system. Background technique [0002] Usually in shops, supermarkets and other stores, most of them pass product information such as prices to customers through paper shelf labels. When using this paper-based shelf label, the product content needs to be printed or printed. When the product content is updated, the shelf label needs to be reprinted or printed, and manual replacement management is required. Since the replacement and maintenance of shelf labels relies heavily on manual work, the replacement and maintenance efficiency of shelf labels is low, and it is prone to errors in product information such as prices. [0003] In order to solve such problems, some electronic shelf label systems have appeared in recent years, which display product information electronical...
