Abstract
An electronic label is provided, including: a first power supply unit, which is configured to supply power to the electronic label; a first control unit, which is configured to monitor at least one of a power supply voltage and a remaining power of the first power supply unit. The first power supply unit includes a first booster circuit, and is configured to turn on the first booster circuit to boost the power supply voltage when at least one of the following conditions is met: the power supply voltage is lower than a first preset voltage threshold; and, the remaining power is lower than a first preset power threshold. The invention also provides a method for monitoring an electronic label, an electronic label monitoring device, and an electronic label system.
