Description
Technical field
The invention relates to a kind of RFID tag module (radio frequencyidentification tag module), and particularly relevant for a kind of RFID tag module with metal tape.
Background technology
(radio frequency identification system is a kind of by the system of radio magnetic wave with the technology of carrying out non-contacting data access (data access) RFIDsystem) to radio-frequency recognition system.Radio-frequency recognition system comprises computer, a reader (reader) and a RFID tag (RFID tag) that has data bank in.Reader is electrically coupled to computer, and RFID tag is disposed on the thing to be identified (identification-required good), and this thing to be identified for example is one the casing (box) of article to be transported (transportation-requiredarticle) to be housed.
When for example being transported out factory and passing through the goods gate for the thing to be identified of casing, the antenna that one of reader is disposed at goods gate place sends wireless signal, and RFID tag receives this wireless signal and returns another wireless signal to reader.Therefore, computer can be according to the information of wireless signal that reader read and built-in data bank, to discern the basic document of this thing to be identified.
Yet, when thing a plurality of to be identified single or that pile up passes through goods gate (goods gate), the article in each thing to be identified or the stacked state of these things to be identified can influence the wireless communication (wireless communication) between reader and each RFID tag, the wireless signal that the antenna that makes the part of these RFID tag can't receive reader is launched.In addition,, also can exert an influence, cause RFID tag to be difficult for being read transmission of wireless signals if the content loaded thing has a large amount of metal ingredient persons in the casing.Therefore, reader can't read the wireless signal that RFID tag is launched effectively, makes the computer of radio-frequency recognition system can't correctly discern the thing to be identified of process goods gate, and then causes the blind spot on the logistics keyholed back plate.In view of this, the induction mode of existing radio-frequency recognition system has improved necessity in fact.
Summary of the invention
The invention provides a kind of RFID tag module, it receives with the ability that transmits wireless signal preferable.
The present invention proposes a kind of RFID tag module, comprises a metal tape (metal band) and a RFID tag (radio frequency identification tag).Metal tape forms a continuous type ring body (continuous ring).RFID tag is adjacent to metal tape and comprises an antenna (antenna) and a chip (chip).Antenna and metal tape produce electromagnetic induction.Chip is electrically coupled to antenna.
Useful technique effect of the present invention is: because the RFID tag module of embodiments of the invention has metal tape, so the accommodating body with above-mentioned RFID tag module is during through the goods gate, the wireless communication between the RFID tag of RFID tag module and the reader more can not be subjected to the interference of the electronic component put accommodating body inside.Therefore, compare with prior art, RFID tag module of the present invention receives with the ability that transmits wireless signal preferable.
For above-mentioned and other purposes, feature and advantage of the present invention can be become apparent, preferred embodiment cited below particularly, and conjunction with figs. are described in detail below.

Embodiment
Figure 1A illustrates the schematic perspective view of a kind of accommodating body of one embodiment of the invention.Figure 1B illustrates the enlarged diagram of the accommodating body of Figure 1A.The accommodating body that Fig. 1 C illustrates a plurality of Figure 1A piles up and synoptic diagram by the goods gate.Please refer to Figure 1A and Figure 1B, the accommodating body of present embodiment (container) C1 comprises a ccontaining body (containing body) B1 and a RFID tag module 200.Ccontaining body B1 for example is a casing, and it has an accommodation space (containingspace) S1.In the present embodiment, the material of ccontaining body B1 can be the material of non-conductive class, and it comprises stationery.Yet in another embodiment, ccontaining body B1 can be the material of conduction class.
It should be noted that RFID tag module 200 can be disposed on the inside surface or outside surface of ccontaining body B1 with being electrically insulated if the material of ccontaining body B1 is the material of non-conductive class.Yet,, be disposed to the insulation of RFID tag module 200 electrotropisms the outside surface of ccontaining body B1 if the material of ccontaining body B1 is the material of conduction class.
Please refer to Figure 1A, Figure 1B and Fig. 1 C, a plurality of accommodating body C1 pile up accommodating body structure T1 with what the mode of Fig. 1 C was stacked into 3 layers and every layer 9 accommodating body C1, and the metal tape 210 of the RFID tag module 200 of these accommodating bodies C1 of each layer almost is positioned on the sustained height.In addition, can put a plurality of electronic components in the ccontaining body B1 of each accommodating body C1, for example be display panels.
When these accommodating bodies C1 that piles up accommodating body structure T1 passes through goods gate D1, reader R1 is by its antenna A1 emission wireless signal, and produce electromagnetic induction between the antenna 224 of the metal tape 210 of each RFID tag module 200 and corresponding RFID tag 220, make each chip 222 receive the wireless signal that reader R1 is sent.Then, each chip 222 is by antenna 224 another wireless signals of emission of correspondence, and produce electromagnetic induction between the antenna 224 of each RFID tag module 200 and the corresponding metal tape 210, make reader R1 receive the wireless signal that each RFID tag 220 is responded.Therefore, be electrically connected to the information of the data bank of wireless signal that the computer C2 of reader R1 can be read according to reader R1 and The built-in, to discern the basic document of these accommodating body C1 that pile up.
This mandatory declaration be, the metal tape 210 of each layer is positioned under the situation of sustained height, the effect of the wireless communication between these RFID tag 220 and the reader R1 is preferable.In addition, in another embodiment, the placing direction of these accommodating bodies C1 of each layer can be done different variations, still can reach the valid wireless signal communicating between these RFID tag 220 and the reader R1.
By as can be known above-mentioned, because the RFID tag module 200 of accommodating body C1 has the metal tape 210 around accommodation space S1, so when a plurality of accommodating body C1 in the mode of piling up during through the goods gate, the RFID tag 220 of each RFID tag module 200 and the wireless communication between the reader more can not be subjected to the interference of the electronic component put accommodating body C1 inside or the influence of piling up disposing way of accommodating body.Therefore, compare with prior art, the reception of each RFID tag module 200 of present embodiment is preferable with the ability that transmits wireless signal.
In sum, the RFID tag module of embodiments of the invention has following one of them or other advantages at least:
One, because RFID tag module of the present invention has metal tape, so the accommodating body with above-mentioned RFID tag module is during through the goods gate, the wireless communication between the RFID tag of RFID tag module and the reader more can not be subjected to the interference of the electronic component put accommodating body inside.Therefore, compare with prior art, RFID tag module of the present invention receives with the ability that transmits wireless signal preferable.
Two, because RFID tag module of the present invention has metal tape, so when a plurality of accommodating bodies passed through the goods gate in the mode of piling up, the wireless communication between the RFID tag of these RFID tag modules and the reader more can not be subjected to the influence of piling up disposing way of these accommodating bodies.Therefore, compare with prior art, the reception of the RFID tag module of embodiments of the invention is preferable with the ability that transmits wireless signal.
