Problems solved by technology

[0002] Current NFC (Near Field Communication, near field communication) tags are generally powered by batteries, and its biggest feature is low power consumption. Even at low frequency, it can only last for about five years. In most cases, the battery The label will be discarded after the power is exhausted, causing a serious waste of resources, and the discarded battery will also cause damage to the environment
For this reason, rechargeable lithium batteries are used in related technologies to extend the working time of tags as much as possible, and reduce operating costs by reducing the frequency of replacement. Communication tags have high energy consumption, do not meet the energy-saving and environmental protection requirements for near-field communication tags, and have low user experience

Abstract

The invention discloses a near-field communication tag and its control system, wherein the near-field communication tag includes: a near-field communication coil for detecting a magnetic field signal when the card reader is within a set range; a control module; and an energy collection module , the energy harvesting module is connected with the near-field communication coil and the control module respectively, and the energy harvesting module is used to convert the magnetic field signal detected by the near-field communication coil into an electrical signal when the near-field communication coil detects a magnetic field signal; the energy storage module, the energy The storage module is respectively connected with the energy collection module and the control module, and the control module is used for controlling the charging of the energy storage module under the action of the electric signal. The near-field communication tag is charged under the action of a magnetic field signal, realizes wireless charging, does not need battery power supply, is more energy-saving and environmentally friendly, and has the advantages of low cost and low power consumption.

Description

technical field [0001] The invention relates to the technical field of electronic tags, in particular to a near-field communication tag and a control system thereof. Background technique [0002] Current NFC (Near Field Communication, near field communication) tags are generally powered by batteries, and its biggest feature is low power consumption. Even at low frequency, it can only last for about five years. In most cases, the battery After the power is exhausted, the label will be discarded, causing a serious waste of resources, and the discarded battery will also cause damage to the environment. For this reason, rechargeable lithium batteries are used in related technologies to extend the working time of tags as much as possible, and reduce operating costs by reducing the frequency of replacement. Communication tags have high energy consumption, do not meet the energy-saving and environmental protection requirements for near-field communication tags, and have low user e...
