Description
Technical field
The present invention relates to technical field of RFID, specifically a kind of bin article for eliminating RFID intelligent cabinet electromagnetic shielding measure
Checking method.
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.
Summary of the invention
The purpose of the present invention is to provide it is a kind of eliminate RFID intelligent cabinet electromagnetic shielding measure bin article checking method,
To solve the problems mentioned in the above background technology.
To achieve the above object, the invention provides the following technical scheme:
A kind of bin article checking method for eliminating RFID intelligent cabinet electromagnetic shielding measure comprising the steps of:
A, RFID antenna array is used in each bin, signal covers all RFID label tags in lattice；
B, RSSI attenuation model is established to each bin；
C, RFID label tag is centainly greater than other bin days by the RSSI maximum value that current bin RFID antenna array is read
The RSSI value that line is read；
D, bin where each label determines according to the RSSI maximum value that each antenna is read, all labels are done equally
The label of processing, the whole each bin storage of cabinet just accurately is made an inventory out.
As further technical solution of the present invention: the read method of the RSSI maximum value is as follows: first taking lattice to be made an inventory
The RSSI maximum value that mouthful RFID antenna array is read, then the RFID label tag that takes other bin RFID antenna arrays to read intersection and
Corresponding RSSI maximum value, then takes the greater in the two RSSI maximum values to every label.
As further technical solution of the present invention: the RSSI maximum value is that each label is rounded all bin RFID of cabinet
The RSSI maximum value that aerial array is read.
As further technical solution of the present invention: the RSSI maximum value is that each label takes bin to be made an inventory and adjacent
The RSSI maximum value that the RFID antenna array of bin is read.
As further technical solution of the present invention: the antenna amount of the RFID antenna array is 1 or 1 or more.
As further technical solution of the present invention: the antenna type of the RFID antenna array is linear polarized antenna, circle
Poliarizing antenna and elliptic polarized antenna.
As further technical solution of the present invention: in the step D, each label takes RFID antenna array to read
RSSI maximum value, bin where determining label according to RSSI maximum value respective antenna.
Compared with prior art, the beneficial effects of the present invention are: compared with the prior art, method proposed by the present invention is not required to
Any additional electromagnetic shielding material is added to the gap between bin and between cabinet door and cabinet body, by each bin
It disposes RFID antenna array and RFID antenna array RSSI maximum is taken to determine bin where RFID label tag, eliminate the interior string of cabinet and read,
It accurately makes an inventory each bin number of articles.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Embodiment 1: please referring to Fig. 1-5, a kind of bin article checking method for eliminating RFID intelligent cabinet electromagnetic shielding measure,
As shown in figure 3, the specific method is as follows: firstly, RFID reader successively scans each bin label, then each label is taken all
The maximum value in RSSI value that RFID antenna array is read, later according to where the corresponding antenna judgement label of RSSI maximum value
Bin, finally counts the label of each bin of single cabinet, and the label of each bin storage of cabinet whole so just accurately is made an inventory out.
Illustrate that specific method, the second bin deploy the second antenna by the second bin, houses third label and the 4th
Label, by the decaying of bin itself, third label by the RSSI value that the first antenna of the first bin above is read is-
72dBm；The RSSI value read by the second antenna of current second bin is -48dBm；By the third antenna of following third bin
The RSSI value read is -68dBm respectively；4th antenna of bottom 4th bin is read less than the label, then 4 antennas
RSSI maximum value is the corresponding -48dBm of the second antenna, then determines the second bin where third label is stored in the second antenna.
It similarly can be determined that the 4th label in the second bin.
Embodiment 2 on the basis of embodiment 1 can also be by taking the RFID of currently bin to be made an inventory and adjacent bin
The RSSI maximum value that aerial array is read determines bin where 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 wait current bin RFID antenna battle array of making an inventory
The RSSI maximum value read is arranged, then the intersection and corresponding RSSI maximum of the RFID label tag for taking other bin RFID antenna arrays to read
Then value takes the greater in the two RSSI maximum values to every label to determine bin where label.Detailed process such as Fig. 5
It is shown.
