A solar electronic tag

Abstract

The invention provides a solar electronic label which comprises a photovoltaic power supply module, a voltage detection module and a main processor. The input end of the main processor is connected with the output end of the voltage detection module, the photovoltaic power supply module supplies power to the modules of the electronic label, and the voltage detection module is used for detecting the output voltage of the photovoltaic power supply module. When the output voltage is smaller than a first voltage threshold value, the main processor controls the electronic label to send a second wireless radio frequency signal according to stored product identifier information when a first wireless radio frequency signal is received. When the output voltage is larger than a second voltage threshold value, the main processor controls the electronic label to read and write the product identifier information to be output according to the received second wireless radio frequency signal, whereinthe first voltage threshold value is smaller than the second voltage threshold value. The intelligence and the convenience of the electronic label can be improved.

Description

technical field [0001] The invention relates to the technical fields of photovoltaic power generation and radio frequency identification, in particular to a solar electronic label. Background technique [0002] With the rapid development of intelligent technology, electronic tags are widely used in industrial automation, commercial automation and other fields, such as anti-counterfeiting, warehouse management, logistics distribution management and production line management. At present, the existing electronic tags include passive electronic tags and active electronic tags. Passive electronic tags have a short recognition distance and require reading devices to provide energy and store less information. Most active electronic tags use batteries to provide energy, and in daily life There are various power consumption situations during use, such as standby power consumption, working power consumption, and abnormal power consumption. Therefore, it is often necessary to replace ...
