Description
Technical field
The utility model will be related to technical field of RFID, specifically a kind of RFID intelligent cabinet dress for eliminating electromagnetic shielding measure
It sets.
Background technique
The existing realization technology of RFID intelligent cabinet is by between cabinet bin and bin and between cabinet door and cabinet body
Gap plus outside electromagnetic shielding material, make bin become independent insulating space, thus realize eliminate RFID scanning cabinet
Interior string is read, the function for each bin number of articles of accurately making an inventory.
The realization technology of the existing additional electromagnetic shield material of RFID intelligent cabinet designs and produces manufacture difficulty in structure
Greatly, finished product yield is lower, and the cabinet of overall cost height enterprise, some types even can not accomplish that bin shields completely at all, and
With the aging of shielding material, shield effectiveness is reduced, and be will appear string between bin and is read, product service life is short.
Utility model content
The utility model by be designed to provide it is a kind of eliminate electromagnetic shielding measure RFID intelligence cabinet device, with solve
The problems mentioned above in the background art.
To achieve the above object, the utility model will provide the following technical solutions:
A kind of RFID intelligence cabinet device for eliminating electromagnetic shielding measure includes multiple RFID intelligent cabinets placed side by side, institute
Show that the top of RFID intelligent cabinet is equipped with RFID reader, the lower section of RFID reader is successively arranged multiple bins from top to bottom, often
RFID antenna array and label are equipped with inside a bin.
As the utility model by further technical solution: the antenna amount of the RFID antenna array be 1 or 1
More than.
As the utility model by further technical solution: the antenna type of the RFID antenna array be elliptic polarization
Antenna.
As the utility model by further technical solution: the antenna type of the RFID antenna array be linear polarization day
Line.
As the utility model by further technical solution: the antenna type of the RFID antenna array be circular polarisation day
Line.
Compared with prior art, the utility model by beneficial effect be: compared with the prior art, the utility model will propose
Method, do not need to add the gap between bin and between cabinet door and cabinet body any additional electromagnetic shielding material, lead to
It crosses deployment aerial array in each bin and aerial array RSSI maximum is taken to determine bin where RFID label tag, eliminate string in cabinet
It reads, each bin number of articles of accurately making an inventory.

Specific embodiment
Below in conjunction with the utility model by the attached drawing in embodiment, to the utility model by the technical solution in embodiment
It being clearly and completely described, it is clear that described embodiment is only the utility model by a part of the embodiment, rather than
Whole embodiments.Embodiment based on the utility model by, those of ordinary skill in the art are not making creative labor
Every other embodiment obtained under the premise of dynamic, belongs to range of the utility model by protection.
Embodiment 1: Fig. 1-5, a kind of RFID intelligence cabinet device for eliminating electromagnetic shielding measure, comprising multiple arranged side by side are please referred to
The RFID intelligent cabinet 1 of placement is equipped with independent RFID reader 2, RFID read-write at the top of each RFID intelligent cabinet 1
Device 2 is used to read the information of label 4, and the lower section of RFID reader 2 is successively arranged multiple bins 5 from top to bottom, in each bin 5
Portion is equipped with RFID antenna array 3 and label 4.Wherein, the antenna amount of RFID antenna array 3 is 1 or 1 or more.Antenna
Type include but is not limited to linear polarized antenna, circular polarized antenna and elliptic polarized antenna.
Its specific works method is as shown in figure 3, the specific method is as follows: firstly, RFID reader 2 successively scans each bin
Label 4 in 5, then each label 4 takes the maximum value in the RSSI value of all readings of RFID antenna arrays 3, later basis
The corresponding antenna of RSSI maximum value determines the bin 5 where label 4, finally counts the label 4 of each bin 5 of single cabinet, whole in this way
The label 4 that each bin 5 of cabinet is stored just accurately is made an inventory out.
Illustrate specific method by second bin 5, as shown in Fig. 2, second bin 5 deploys antenna 2, houses two
A label, by the decaying of bin 5 itself, the label 4 in left side by the RSSI value that the antenna 1 of bin 5 above is read is-
72dBm；The RSSI value read by the antenna 27 of current second bin is -48dBm；It is read by the antenna 38 of following bin 5
The RSSI value got is -68dBm respectively；The antenna 49 of bottom bin 5 is read less than the label, then the RSSI of 4 antennas
Maximum value is the corresponding -48dBm of antenna 27, then determines second bin 5 that label 3 is stored in where antenna 27.Similarly may be used
To determine label 4 in second bin 5.
Embodiment 2 on the basis of embodiment 1 can also be by taking currently bin 5 and adjacent bin 5 to be made an inventory
The RSSI maximum value that RFID aerial array 3 is read determines 4 place bin 5 of label.Detailed process is as shown in Figure 4.
Embodiment 3, on the basis of embodiment 1, furthermore it is also possible to first currently take RFID days wait current bin 5 of making an inventory
The RSSI maximum value that linear array 3 is read, then the intersection of the label 4 that takes the RFID antenna array 3 of other bins 5 to read and corresponding
Then RSSI maximum value takes the greater in the two RSSI maximum values to every label 4 to determine bin where label.Specifically
Process is as shown in Figure 5.
It is obvious to a person skilled in the art that the utility model is not limited to the details of above-mentioned exemplary embodiment,
And without departing substantially from the utility model by spirit or essential attributes in the case where, can realize this reality in other specific forms
It is incited somebody to action with novel.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this
Utility model by range be indicated by the appended claims rather than the foregoing description, it is intended that being equal for claim, will be fallen in
All changes in the meaning and scope of important document are included will be interior in the utility model.It should not be by any attached drawing mark in claim
Note is construed as limiting the claims involved.
In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped
Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should
It considers the specification as a whole, the technical solutions in the various embodiments may also be suitably combined, forms those skilled in the art
The other embodiments being understood that.
