Breath, and result is transmitted to system centre service；
B, pass through in logical RFID label tag recognizing apparatus identification range when a luggage, system can be collected into n times on
The data message of RFID label tag, and these data, from multiple different passages, system carries out data and once cleans first, right
The different RFID label tags of same luggage carry out returning master；
The number of times of C, the RFID label tag that will can be collected in knowledge and magnanimity stage, computing comparing module, quantity is stored in a label
Two dimensional model in, this model include time shaft, valid data；
D, when the knowledge and magnanimity stage complete, system carries out calculus of differences to the sampling model of each passage, in the mould of multiple passages
Interfering channel is found out in type, and is removed, draw unique match passage；Using second order difference method, basic formula is：△2Yt=△
(△ Yt)=△ Yt+1- △ Yt=Yt+2-2Y t+1+Yt (Yt is values of the Y in t).
E, system take the one-to-one matching of people's luggage and passage, afterwards according to preset Service control flow to gate and correlation
Equipment is controlled.
Compared with prior art, the beneficial effects of the invention are as follows：
(1) present invention can guarantee that RFID recognition device to the leakage knowledge rate of RFID label tag under the premise of 0, to recognize RFID label tag；
In the case of can solve the problem that multiple RFID recognition devices read a RFID simultaneously simultaneously, specific knowledge can be accurately judged
Other equipment.
(2) in the present invention, more than 2 groups of identification antenna has been installed additional in luggage passage, it is adjacent very in multigroup RFID passages
In the case of near, when label passes through passage, can be recognized by adjacent multiple passage RFID devices, and in the present invention, protected
On the premise of card leakage knowledge rate is 0, by creating data model and degree of correlation matching algorithm, and in system each functional module pass
Connection coordinates, the lifting label that identifies of single channel be the matching rate of the label passed through in this passage more than 99.9%, significantly
The misclassification rate for reducing system, it is ensured that the recognition accuracy of system equipment.
Brief description of the drawings
Fig. 1 is system principle diagram of the invention；
Fig. 2 is workflow diagram of the invention.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Fig. 1-2 is referred to, the present invention provides a kind of technical scheme：A kind of anti-error read apparatus of multichannel RFID label tag, including
RFID label tag recognizing apparatus 1, control module 2, memory module 3, RFID recognition module 4, alarm module 5 and data operation are compared
Module 6, the RFID label tag recognizing apparatus 1 are arranged in luggage passage, the connection of the RFID label tag recognizing apparatus 1 RFID recognitions
Module 4, the RFID distinguishes the link control module 2 of module 4, and the control module 2 is also respectively connected with memory module 3, alarm mould
Block 5 and data operation comparing module 6.
In the present embodiment, 2-6 groups identification antenna is also equipped with luggage passage, in the present invention, is installed additional in luggage passage
More than 2 groups of identification antenna, multigroup RFID passages it is adjacent it is close in the case of, when label passes through passage, can be by adjacent
Multiple passage RFID devices are recognized, and in the present invention, on the premise of ensureing that leakage knowledge rate is 0, by creating data model
And degree of correlation matching algorithm, and the association of each functional module coordinates in system, the label that lifting single channel is identified is this
The matching rate of the label passed through in passage greatly reduces the misclassification rate of system, it is ensured that system equipment more than 99.9%
