Low-power-consumption optical-energy electronic tag

Abstract

Disclosed in the invention is a low-power-consumption optical-energy electronic tag comprising an optical energy collection module, a wireless charging module, an energy storage module, a controller, a wireless data storage module, a wireless data reading-writing module, an electric paper display module and a wireless data communication module. The controller is connected with the wireless data storage module electrically; and the wireless data storage module is connected with the wireless data reading-writing module electrically. A solar cell panel is arranged on the top of a tag body; an electric paper display screen is arranged at one side of the tag body; and a rechargeable battery is arranged at one side of the controller. According to the optical-energy electronic tag, the consumption speed of the power inside the battery can be decreased; energy conservation and environment protection are realized; the charging way of the batter is increased; a phenomenon that the electronic tag can not work normally due to insufficient power supply can be prevented; and practicability and work stability of the electronic tag are improved. With the electric paper display ways, the electric energy consumption can be reduced effectively; the battery load is reduced; the service life of the battery is prolonged; and the cost is lowered.

Description

technical field [0001] The invention relates to an electronic label, in particular to a light energy electronic label with low power consumption. Background technique [0002] With economic development and technological progress, remote sensing electronic tags have entered various application fields; remote sensing electronic tags can be divided into passive electronic tags and active electronic tags from the power supply mode; The device obtains energy, while the active electronic tag obtains energy directly from an external power source. [0003] However, the active electronic tags that appear on the market today are powered by batteries, and the batteries need to be powered all the time, resulting in a large amount of power consumption and a waste of resources; and the way to charge the batteries is too simple, which may lead to insufficient battery power and make the Active electronic tags do not work properly. In terms of display of active electronic tags, the traditi...
