Description of drawings

To combine accompanying drawing and embodiment that the utility model is described further below, in the accompanying drawing:

Fig. 1 is the logic diagram of the RFID tag read device of the utility model embodiment.

Embodiment

For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

As shown in Figure 1, be used for the RFID label is read and write according to the RFID tag read device of the utility model, this RFID tag read device comprises a plurality of read-write antenna 100, antenna handover module 200 and processing module 300.

Wherein, a plurality of read-write antennas 100 shown in Fig. 1 comprise the read-write

antenna

1001,1002 ..., 100n, will use wherein any one of read-write antenna 100 representative below.Each above-mentioned read-write antenna 100 can corresponding RFID label.General RFID label comprises the RFID chip that stores its unique identity information and is used to receive and dispatch the RFID antenna of radiofrequency signal.Above-mentioned each read-write antenna 100 can be corresponding with it a RFID label the RFID antenna separately and coupling separately, thereby read-write antenna 100 can confirm to RFID antenna receiving-sending radiofrequency signal, thereby a certain assigning RFID label is is accurately read and write in realization.

Antenna handover module 200 comprises interface unit 210 and switch unit 220, all is electrically connected with above-mentioned each read-write antenna 100.One side interface unit 210 can be read and write antenna 100 with each and carry out the radiofrequency signal exchange; Can switch through the 210 pairs of read-write antennas 100 in switch unit 220 control interface unit on the other hand, thereby the read-write antenna 110 that inserts in the operation is this time confirmed in the work of control read-write antenna 100.

Processing module 300 comprises radiofrequency signal processing unit 310 and the control module 320 that is electrically connected with this radiofrequency signal processing unit 310, can carry out exchanges data between the two.Wherein, radiofrequency signal processing unit 310 also is electrically connected with the interface unit 210 of antenna handover module 200, thereby can carry out the radiofrequency signal exchange with interface unit 210.On the one hand, can be from interface unit 210 received RF signals, be sent to control module 320 after converting the radiofrequency signal that receives to electric signal, by control module 320 it is handled.On the other hand, can send radiofrequency signal (for example lastest imformation), send to corresponding RFID label through read-write antenna 100 again to interface unit 210.Control module 320 also is electrically connected with the switch unit 220 of antenna handover module 200, thereby can carry out exchanges data with switch unit 220.Control module 320 through decide to switch unit 220 input control orders the read-write

antenna

1001,1002 ..., 100n job order, for example, decision is that the mode according to training in rotation inserts read-write antenna 100, still specifies and inserts a certain read-write antenna 100.

In operating process according to the RFID tag read device of the utility model; Control module 320 sending controling instructions give the switch unit 220 of antenna handover module 200 to confirm to insert the mode of read-write antenna 100; For example training in rotation mode or specific mode will be that example is described with the training in rotation mode below.After control module 320 specifies switch unit 220 to insert read-write antenna 100 according to the training in rotation mode; For example at first insert read-write antenna 1001001; On the one hand; Read-write antenna 1001 receives the radiofrequency signal that comprises this RFID label identity information from the RFID label, and the radiofrequency signal that receives is sent to the radiofrequency signal processing unit 310 of processing module 300; Radiofrequency signal processing unit 310 sends to control module 320 after converting this radiofrequency signal to electric signal; Control module 320 has obtained the identity information of this RFID label immediately, and can carry out analyzing and processing to identity information, for example, carries out The matching analysis etc.On the other hand, control module 320 can also be managed the identity information in the RFID label, and particularly, control module 320 sends the identity information that upgrades with the form of electric signal and gives radiofrequency signal processing unit 310; The electrical signal conversion that radiofrequency signal processing unit 310 will comprise the identity information of renewal becomes radiofrequency signal, and sends to interface unit 210; Thereby the identity information that will upgrade through the read-write antenna 1001 that inserts is written in the RFID chip of RFID label, thereby realizes the management to the RFID label.When read-write equipment need carry out when mutual another one RFID label; Switch unit 220 for example inserts read-write antenna 1002 according to the training in rotation mode; Adopt read-write antenna 1002 to carry out alternately, comprise and obtain identity information and identity information managed etc. with this another RFID label.And the like, other read-write antenna 100 can carry out with other RFID label alternately, read-write antenna 100 corresponding RFID labels in the reciprocal process.

Can find out from above; In the RFID of the utility model tag read device; Through a plurality of read-write antennas are set; And the antenna handover module is set to insert the read-write antenna according to certain mode, can realize corresponding RFID label of read-write antenna in the operation, through the read-write antenna that inserts an independent RFID label is managed separately and operated.Thereby in implementation procedure, do not need the corresponding read-write equipment of a RFID label, only need a read-write equipment to get final product, therefore practiced thrift cost, made things convenient for operation yet, need not carry a plurality of read-write equipments in the operation.

Should be understood that, concerning those of ordinary skills, can improve or conversion, and all these improvement and conversion all should belong to the protection domain of the utility model accompanying claims according to above-mentioned explanation.
