摘要:
Disclosed herein is an electronic shelf label system. The electronic shelf label system includes a plurality of electronic tags that are installed on a product display stand and confirms the residual amount of a battery to turn-on a battery warning light when the residual amount is smaller than a reference voltage and transmits replacement request signals to inform the replacement time of the battery; and a wired/wireless communication converter that relays information between the electronic tags and a server and transmits the replacement request signals received from the electronic tags to be relayed thereby to the server. The electronic shelf label system of the present invention can intuitively and easily confirm the timing when the battery of the electronic is replaced, thereby making it possible to improve the efficiency in the working of replacing the battery.

Disclosed herein is an electronic shelf label system. The electronic shelf label system includes a wired/wireless converter wirelessly transmitting product information according to request of a server, at least one rail installed on a product display stand and including a plurality of electrical wirings, at least one first electronic tag installed in the rail and performing wireless communication with the wired/wireless converter, and a plurality of second electronic tags each installed in the rail and performing wired communication with the first electronic tag through the electronic wirings. The electronic shelf label system uses the hybrid communication in which wire and wireless are mixed, thereby making it possible to provide the smooth communication environment by removing a shadow area of communication while dispersing communication traffic.

Provided a wideband chip antenna in which the outer surface of a dielectric or magnetic body block is surrounded by a conductor. The wideband chip antenna comprises one or more slots or slits that are formed on the top surface of the wideband chip antenna and of which predetermined portions are opened; one or more slits that are formed on the bottom surface of the wideband chip antenna and of which predetermined portions are opened; and one or more windows that are formed on one or more side surfaces of the wideband chip antenna by opening predetermined portions thereof. The wideband chip antenna can simultaneously transmit and receive signals at various bands, and the size thereof can be reduced. Further, the resonance property of the antenna can be easily adjusted, and a wider bandwidth can be secured.
