Description

But the RFID screen display label of wireless charging

Technical field

The utility model relates to the RFID technical field, but particularly a kind of RFID screen display label of wireless charging.

Background technology

Radio-frequency (RF) identification (RFID) technology is a kind of contactless automatic identification technology, and it can automatically be identified target and obtain desired data by radiofrequency signal.The RFID electronic tag is the core of RFID technology, is the real data carrier of rfid system.

The RFID electronic tag is divided into passive and active two kinds.The passive RFID electronic label decipherment distance is short, transmitted data amount is little, need the higher power of read write line emission.Type active RFID electronic label has overcome the deficiency of passive RFID electronic label, but depend on battery serviceable life, generally at 1-2, relatively short, some type active RFID electronic labels have been reserved replacement structure of battery, but Renewal process is very loaded down with trivial details, and expense is high, efficiency is low, uses inconvenient.

Therefore, but the RFID technical field is badly in need of that a kind of decipherment distance is long, transmitted data amount is large, long service life and have the RFID screen display label of the wireless charging of screen display function.

The utility model content

But the utility model provides a kind of RFID screen display label of wireless charging, and technical scheme is as follows:

But the RFID screen display label of wireless charging, is characterized in that, comprising:

The rectification circuit module, an end is connected with the energy receiving antenna, and the other end is connected with rechargeable battery;

This rechargeable battery, be connected with radio-frequency communication module, single-chip data processing module, display module;

This radio-frequency communication module, an end is connected with the signal transmitting and receiving antenna, and the other end is connected with this single-chip data processing module;

This single-chip data processing module, be connected with this display module.

The beneficial effects of the utility model are:

1. but the RFID screen display label of wireless charging, have the functions such as decipherment distance is long, transmitted data amount is large, screen display.

2. but the RFID screen display label of wireless charging is improved on the basis of original type active RFID electronic label, cost-saving, increases economic efficiency.

3. but the RFID screen display label of wireless charging, adopt rechargeable battery, and can adopt the wireless charging mode to be charged to rechargeable battery, extended serviceable life, practical and convenient, has applicability widely.

The accompanying drawing explanation

Describe the utility model in detail below in conjunction with the drawings and specific embodiments:

But Fig. 1 is the process flow diagram of the RFID screen display label of the utility model wireless charging.

Embodiment

For measure, creation characteristic that the utility model technology is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

But Fig. 1 is the process flow diagram of the RFID screen display label of the utility model wireless charging.The utility model comprises:

Rectification circuit module 102, one ends are connected with energy receiving antenna 101, and the other end is connected with rechargeable battery 103;

Rechargeable battery 103, be connected with radio-frequency communication module 104, single-chip data processing module 105, display module 106;

Radio-frequency communication module 104, one ends are connected with signal transmitting and receiving antenna 107, and the other end is connected with single-chip data processing module 105;

This single-chip data processing module 105, be connected with this display module 106.

During the utility model work, energy receiving antenna 101 receives electromagnetic radio-frequency (RF) energy based on electromagnetic induction principle, and radio-frequency (RF) energy is changed into to high-frequency current be sent to rectification circuit module 102, rectification circuit module 102 changes into DC current by high-frequency current, rechargeable battery 103 is charged, 103 pairs of radio-frequency communication module 104 of rechargeable battery, single-chip data processing module 105, display module 106 power supplies.
