Abstract
The utility model discloses a kind of RFID supervisory system, be mainly used in Wine cellar, comprise RFID label tag, RFID antenna, rfid interrogator and application system, the utility model significantly improves the Sensitivity of intensive aerial array to the response signal of RFID label tag; Effectively prevent the cross jamming of adjacent antenna.
Description
Technical field
The present invention relates to monitoring technique field, relate in particular to a kind of RFID supervisory system being mainly used in Wine cellar.
Background technology
Traditional grape wine process technology comprises the link of preserving new wine with wine cellar.Due to the special storage performance of wine product, grape wine is to the internal environment in wine cellar, and putting position etc. have strict requirement, adds suitable supervisory system be conducive to the management of wine product and the quality promoting wine product for wine cellar.
RFID is a kind of non-contact automatic identification technology, automatically identify destination object by radiofrequency signal and obtain related data, in prior art, exist by RFID label tag is attached on burgundy bottle, with the RFID antenna be placed under wine cabinet, information reading is carried out to RFID label tag, information is sent to rfid interrogator by RFID antenna, and rfid interrogator is sent to application system to after information acquisition decoding, thus carries out the technology of system management to the position that grape wine is placed.
But there is following defect in this technology:
In prior art, rfid interrogator is as follows to gathered RFID label tag response signal processing mode: carrier wave, by detecting circuit, is removed by the carrier signal first RFID label tag read; Then, the signal unloading ripple is amplified through amplifier; Then, be mingled with the tag response signal of noise by comparator circuit by after amplification, the value as input voltage is large compared with fiducial value, and output valve is 1, otherwise output valve is 0, and so far, the response signal of RFID label tag is detected.
And be the demand meeting wine cellar technique, in practice, often there is the crisscross intensive situation of putting of multiple wine cabinet.In this case, the transmission range of signal of RFID antenna will inevitably cover other adjacent RFID antenna, even if control to work when two adjacent R FID antennas are different, the coil of adjacent R FID antenna also can produce electromagnetic induction thus cause cross jamming to the signal of the RFID antenna of duty.
Those skilled in the art need play creationary thinking, promote and read accuracy rate to the RFID label tag of the wine cellar supervisory system based on RFID.
Summary of the invention
The utility model provides a kind of Wine cellar supervisory system based on RFID, is intended to make up above-mentioned technological deficiency.
The technical scheme that the utility model adopts is as follows:
A kind of RFID supervisory system, comprises RFID label tag, RFID antenna, rfid interrogator and application system; Described RFID antenna reads described RFID label tag and carries out information transmission to described rfid interrogator, and described rfid interrogator is sent to described application system to after information acquisition decoding; It is characterized in that: described rfid interrogator comprises detecting circuit, amplifying circuit, filtering circuit and analog to digital converter.
Based on a Wine cellar supervisory system of RFID, comprise RFID label tag, RFID antenna, rfid interrogator and application system; Described RFID label tag embeds on bottle, described RFID antenna embeds in the underlay screen of the wine cabinet placing bottle, described RFID antenna is carried out reading process to described RFID label tag and is carried out information transmission to described rfid interrogator, and described rfid interrogator is sent to described application system to after information acquisition decoding; It is characterized in that: described rfid interrogator comprises detecting circuit, amplifying circuit, filtering circuit and analog to digital converter.
Preferred scheme is further: the multiple RFID antenna comprising at least 2 placed by the wine cabinet of each placement bottle, and all RFID antenna form intensive aerial array in Wine cellar.
Compared with prior art, technique effect of the present invention is: by the change to rfid interrogator structure, improves the read-write sensitivity of the rfid interrogator of multiple antennas in zonule, effectively controls the cross jamming between RFID antenna.

Embodiment
The present invention will be further described for the embodiment of showing below in conjunction with accompanying drawing.
As Fig. 1, the embodiment 1 shown in 2:
A kind of Wine cellar supervisory system based on RFID, comprise RFID label tag 1, RFID antenna 2, rfid interrogator 3 and application system 4, RFID antenna 2 reads the information of RFID label tag 1, the information of reading is sent to rfid interrogator 3 by RFID antenna 2, and rfid interrogator 3 sends to application system 4 after detecting the response signal of RFID label tag 1;
Described RFID label tag 1 embeds on bottle, and described RFID antenna 2 embeds in the underlay screen of the wine cabinet placing bottle, and RFID antenna 2 is arranged according to the concrete distribution of wine cabinet, forms intensive antenna array in Wine cellar.
Comparison diagram 3 and Fig. 4:
The rfid interrogator 3 of prior art comprises: detecting circuit 31, amplifying circuit 32 and comparator circuit 33; Rfid interrogator of the present utility model comprises: detecting circuit 31, amplifying circuit 32, filtering circuit 34 and analog-to-digital conversion device 35.
Prior art and difference of the present utility model are: prior art, by by being mingled with the RFID label tag response signal of noise by comparator circuit 33, according to the comparing result of the response signal and fiducial value that will be mingled with noise, directly obtains the Output rusults of 0 or 1.
And the processing scheme of rfid interrogator of the present utility model to RFID response signal is: first pass through detecting circuit 31 to the carrier signal that RFID label tag 1 reads, carrier wave is removed; Then, the signal unloading ripple is amplified through amplifier circuit 32; Then, the response signal being mingled with the RFID label tag 1 of noise after amplification is carried out filtering partial noise by filtering circuit 34; Finally, the response signal of filtered RFID label tag 1 is converted to digital signal by analog to digital converter 35 at a high speed, and rejects the noise section in this signal by existing algorithm, thus the response signal of RFID label tag 1 is detected.
The superiority of this mode is: fiducial value that is direct for the response signal being mingled with noise and comparator circuit compares and draws 0 or 1 of digital output value by prior art; Because criterion is single, the concrete condition of noise and response signal cannot be understood definitely, and then response signal is made judge accurately.And the utility model carries out high speed analog-to-digital conversion to the response signal of RFID label tag, draw its waveform, by existing algorithm rejecting noise section wherein, detect response signal, significantly improve the sensitivity detected of the response signal of RFID label tag 1; Effectively prevent the cross jamming of adjacent antenna.
The above, be only a certain item embodiment of the present utility model, the present invention is not limited to the restriction of above-described embodiment, and protection scope of the present invention is only defined by claims.
