Description
Technical field
This utility model relates to RF identification (RFID, Radio Frequency Identification) technology, particularly relates to a kind of RFID label tag.
Background technology
Along with the fast development of wireless communication technology, RFID technique is monitored efficiently as one and is applied to various occasion such as charge station, supermarket etc. with recognition methods.RFID is a kind of contactless automatic identification technology, relates to chip, antenna, wireless receiving and dispatching, data conversion and coding and numerous ambits such as electromagnetic wave and electromagnetic field.Compared with bar code identification technology, magnetic card identification technology and IC-card identification technology etc., distinctive untouchable, capacity of resisting disturbance is strong, can identify the advantages such as multiple objects simultaneously with it for RFID, has been increasingly becoming one of fitst water in automatic identification family and widest technology of application.Conventional RFID tag has broadband character, with two the RFID communication frequency ranges (840-845MHz and 920-925MHz) supporting GB to define simultaneously.Owing to RFID communication uses near field communication technology, other signals of communication around applied environment are lost due to wireless channel, typically do not interfere with RFID proper communication.But, when RFID technique being incorporated in indoor distribution communication system, when being used for monitoring indoor distribution passive device, RFID communication can be caused very strong jamming by indoor communications signal (such as GSM900), causes rfid system normally to work.
Utility model content
For solving above-mentioned technical problem, this utility model embodiment provides a kind of RFID label tag.
The technical scheme of this utility model embodiment is as follows:
A kind of wireless radio frequency discrimination RFID label, described RFID label tag includes: antenna, SAW filter and RFID label chip；Described antenna electrically connects with described SAW filter, and described SAW filter electrically connects with described RFID label chip；Described RFID label chip is communicated with RFID card reader by described antenna；Described SAW filter filters the interference signal outside RFID working band scope.
In this utility model embodiment, described antenna includes the plane microstrip antenna being arranged on printing board PCB.Can also be other form antennas.
In this utility model embodiment, described RFID label tag also includes the bar code at front or the back side being arranged at described RFID label tag；Described bar code characterizes the identification information of described RFID label tag.
In this utility model embodiment, described bar code includes one-dimensional or two-dimensional bar.
In the structure of the RFID label tag of this utility model embodiment, SAW filter is set between RFID label chip and antenna, SAW filter suppresses the high and low frequency interference signal outside working band, improve the interference free performance of RFID label tag.Even if the RFID label tag of this utility model embodiment being incorporated in indoor distribution communication system, RFID communication will not be interfered by indoor communications signal.It addition, the id information of RFID label tag is converted to one-dimensional or two-dimensional bar by this utility model embodiment, and it is affixed on RFID label tag surface, it is simple to use the equipment such as general purpose hand-held mobile terminal such as mobile phone to read, convenient and swift.

Detailed description of the invention
In order to more fully hereinafter understand feature and the technology contents of this utility model embodiment, the realization to this utility model embodiment is described in detail below in conjunction with the accompanying drawings, appended accompanying drawing purposes of discussion only for reference, is not used for limiting this utility model embodiment.
Fig. 1 is the structure composition schematic diagram of the RFID label tag of this utility model embodiment, as it is shown in figure 1, the RFID label tag of this utility model embodiment includes: antenna, SAW filter and RFID label chip；Described antenna electrically connects with described SAW filter, and described SAW filter electrically connects with described RFID label chip；Described RFID label chip is communicated with RFID card reader by described antenna；Described SAW filter filters the interference signal outside RFID working band scope.
In this utility model embodiment, described antenna includes the plane microstrip antenna being arranged on printing board PCB, it is also possible to for other form antennas, as long as can be arranged in RFID label tag, and can communicate with RFID card reader.
Fig. 2 is the external structure schematic diagram of the RFID label tag of this utility model embodiment, as in figure 2 it is shown, in this utility model embodiment, described RFID label tag also includes the bar code at front or the back side being arranged at described RFID label tag；Described bar code characterizes mark (ID) information of described RFID label tag.In this utility model embodiment, described bar code includes one-dimensional or two-dimensional bar.
Below by way of concrete example, it is further elucidated with the essence of the technical scheme of this utility model embodiment.
The RFID label tag of this utility model embodiment is the anti-interference RFID label tag being integrated with surface acoustic wave (SAW, Surface Acoustic Wave) band filter, and the interference signal outside RFID working band can be suppressed for the impact of RFID proper communication.Simultaneously, by printing one-dimensional or two-dimensional bar outside RFID label tag, the id information of RFID label tag is converted to the one-dimensional or two-dimensional bar information being prone to read, it is to avoid use RFID card reader, only uses general mobile terminal equipment i.e. to can read the id information of RFID label tag.
The anti-interference RFID label tag internal structure that this utility model embodiment proposes is as it is shown in figure 1, include antenna, SAW filter and RFID label chip.Wherein:
Antenna: antenna is usually the plane microstrip antenna on pcb board material, it is also possible to for other form antennas；
SAW filter: be used for filtering outside RFID working band that to disturb signal, filter passband scope be RFID working band scope；
RFID label chip: for common RFID tag chip, be used for communicating with RFID card reader.
For the ease of reading the id information within RFID label tag, the id information of RFID label tag is also converted to common one-dimensional or two-dimensional bar form, and is printed upon on RFID label tag front or the back side, as shown in Figure 2 by this utility model embodiment.When needing the id information inquiring about RFID label tag, it is only necessary to use wireless universal mobile device (such as smart mobile phone) to scan one-dimensional or two-dimensional bar acquisition id information.
In the structure of the RFID label tag of this utility model embodiment, SAW filter is set between RFID label chip and antenna, SAW filter suppresses the high and low frequency interference signal outside working band, improve the interference free performance of RFID label tag.Even if the RFID label tag of this utility model embodiment being incorporated in indoor distribution communication system, RFID communication will not be interfered by indoor communications signal.It addition, the id information of RFID label tag is converted to one-dimensional or two-dimensional bar by this utility model embodiment, and it is affixed on RFID label tag surface, it is simple to use the equipment such as general purpose hand-held mobile terminal such as mobile phone to read, convenient and swift.
The above; it is only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that this utility model discloses; change can be readily occurred in or replace, all should contain within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with described scope of the claims.
