Passive electronic tag system

Abstract

A passive electronic tag system comprises an LED light bar, the LED light bar is connected with an electronic tag, and the electronic tag is connected with a system base station. The electronic tag comprises a circuit board, a display screen, a thin-film solar panel and a tag shell. The circuit board, the display screen and the thin-film solar panel are arranged in the label shell; an energy storage module, a control module, a first wireless communication module and a display driving module are arranged on the circuit board; the thin-film solar panel is connected with the energy storage module; the energy storage module is connected with the control module; the control module is connected with the first wireless communication module and the display driving module, and the display driving module is connected with the display screen; the LED light bar is adjacent to the thin-film solar panel, the system base station is provided with a third wireless communication module and a CPU processing module, the CPU processing module is connected with the third wireless communication module, and the third wireless communication module is connected with the first wireless communication module.The power supply mode is reliable, operators do not need to update one by one on site, and time and labor are saved.

Description

technical field [0001] The invention relates to an electronic label system, in particular to a passive electronic label system. Background technique [0002] At present, electronic tags have begun to be widely used in supermarket systems. Their features such as remote price adjustment and low power consumption under static conditions are an upgraded substitute for traditional paper. However, the electronic tags currently on the market basically use button batteries as the power source. Based on the industry's usual requirement of 3-5 years of use, the electronic tags must plan their working methods with the lowest energy consumption, and a large amount of time must be spent sleeping. On the one hand, the sleep state affects the response timeliness of the electronic tag, and on the other hand, it also limits the scalability of more functions such as the flashing light and the splash screen of the electronic tag. There are also some electronic label systems that use wired pow...
