The invention discloses a base station power supply device and an electronic price tag system, and relates to the technical field of electronic price tags. The base station power supply device comprises an input power supply interface module which comprises an adapter input power supply interface, a POE input power supply interface and a USB input power supply interface and is used for providing power supply input interfaces for an adapter power supply, a POE power supply and a USB power supply; the POE module is connected with the adapter input power supply interface and the POE input power supply interface and used for receiving an adapter power supply input through the adapter input power supply interface and a POE power supply input through the POE input power supply interface so as to realize seamless and rapid switching between the adapter power supply and the POE power supply to supply power to the base station; the USB input power supply interface is connected with a base station, and a USB power supply directly supplies power to the base station through the USB input power supply interface; and the switching circuit is connected with the POE module and controls the POE module to output voltage to supply power to the base station. According to the embodiment of the invention, the power supply stability of the base station is improved, and the operation reliability of the electronic price tag system is ensured.
Description
technical field [0001] The invention relates to the technical field of electronic price tags, in particular to a base station power supply device and an electronic price tag system. Background technique [0002] Electronic Shelf Label, also called Electronic Shelf Label (ESL), is an electronic display device with information sending and receiving function, which is mainly used in electronic labels for displaying price information in supermarkets, convenience stores, pharmacies, etc. The electronic price tag can be placed on the shelf and can replace the electronic display device of the traditional paper price tag. Each electronic price tag is connected to the computer database of the shopping mall through a wired or wireless network, and the latest commodity information is displayed on the electronic price tag. screen is displayed. In fact, the electronic price tag successfully incorporated the shelf into the computer program, got rid of the situation of manually replacing ...
