Module 18 is to support the multichannel RFID module 18 of mutiple antennas 16, such as the RFID reader of multiport.In this way, mutiple antennas
16 can arrange in pairs or groups the small number of RFID module 18 such as one or two, can be realized under the control of control unit 20, pass through
The alien frequencies work simultaneously of mutiple antennas 16 further increases recognition efficiency to identify to article at the same time it can also reduce O&M
Cost.
Fig. 4 to Fig. 7 is please referred to, in one embodiment, the quantity of RFID module 18 is at least two, each RFID module 18
Control unit 20 is communicated to connect respectively.Preferably, in the present embodiment, at least two RFID moulds are provided on article-storage device 100
Block 18, each RFID module 18 under the control of control unit 20, respectively drive each antenna 16 communicated to connect thereon simultaneously simultaneously
Alien frequencies work.
Specifically, as shown in Figure 4 and Figure 5, by taking two RFID modules 18 of dual-port work at the same time as an example: in control unit
Under the logic level signal control of 20 outputs, at the T1 moment, the first RFID module 18 and the second RFID module 18 are in preparation
Working stage.Antenna 16 on the T2 moment, the port 1 of the first RFID module 18 works in X frequency range；Second RFID module 18
Antenna 16 on port 1 works in Y frequency range, since X and Y frequency range is not overlapped, so the day on the port 1 of the first RFID module 18
Antenna 16 on the port 1 of line 16 and the second RFID module 18 can complete same time alien frequencies work.At the T3 moment, level is again
Low level is returned, the work of subsequent time is prepared.At the T4 moment, the work of antenna 16 on the port 1 of the first RFID module 18 is in Y frequency
Section, the antenna 16 on the port 1 of the second RFID module 18 works in X frequency range, this is exactly the opposite with the working method at T2 moment.Such as
This, the first RFID module 18 is work in the moment in X+Y frequency range (such as 920MHz to 925MHz frequency range) from T1 to T4, second
RFID module 18 is also work in the moment in X+Y frequency range (such as 920MHz to 925MHz frequency range) from T1 to T4.So repeat
T1 to T4 moment, work while can realizing double antenna.
It similarly, is the day on other ports in the first RFID module 18 and the second RFID module 18 by control unit 20
Line 16 also distributes two setting frequency ranges, by control logic same as before, realizes the first RFID module 18 and the 2nd RFID mould
Antenna 16 on block 18 on all of the port works at the same time, and at any one time, and each antenna 16 is in different setting frequencies
Work in section, each antenna 16 exchange setting frequency range in different moments, so that each antenna 16 traverses each setting frequency range work,
The scan efficiency for effectively improving each antenna 16 greatly improves Item Information acquisition speed.
As shown in Figure 6 and Figure 7, by taking two RFID modules 18 of four ports work at the same time as an example: being exported in control unit 20
Logic level signal control under, 1 antenna 16 of port of the first RFID module 18 works at the T2 moment in X frequency range, in order to complete
Alien frequencies works while double antenna, and control unit 20 can select an antenna 16 aforementioned antenna therewith in the second RFID module 18
16 pairing works.As shown in 7 figures, the antenna 16 on port 2 in the second RFID module 18 or the antenna 16 on port 3 can
It is worked at the same time with 1 antenna 16 of port of the first RFID module 18.As time goes by, at the T4 moment, antenna 1 works in Y frequency range,
And then relevant work is in X frequency range for the antenna 16 on the antenna 16 or port 2 on the port 2 in the second RFID module 18, so
It can make mutually match 2 antennas that can work independently in different frequency ranges at various moments, to realize two of four ports
Double antenna alien frequencies work simultaneously between RFID module 18.
Similarly, 2 antenna 16 of port of the first RFID module 18 works at the T2 moment, can be with the second RFID module 18
Antenna 16 on antenna 16 or port 4 on port 1 carries out pairing work.For on the port 3 of the first RFID module 18
For antenna 16, in the present embodiment due to only with two frequency ranges of X and Y, and the two frequency ranges are same by both of the aforesaid
When the antenna 16 that works occupy, therefore the antenna 16 on the port 3 of the first RFID module 18 can not be same with both of the aforesaid at the T2 moment
When the antenna 16 that works work at the same time, control unit 20 can distribute newly for the antenna 16 on the port 3 of the first RFID module 18
A setting frequency range, can be added and work at the same time.In this way, by needing the antenna 16 worked at the same time to distribute identical quantity to be each
Setting frequency range, control unit 20 can control each RFID module 18 to drive the work of each 16 alien frequencies of antenna simultaneously, and worked
Each antenna 16 of control in journey carries out frequency range rotation, and the promotion of further 16 scan efficiency of antenna can be realized.For more
The RFID module 18 of multiport can ibid understand, as long as by control unit 20 be RFID module 18 each antenna 16 at the same time
Different setting frequency ranges is distributed when work.
