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 RFID management system for Medical refrigerator, is installed within Medical refrigerator, comprises RFID label tag 1, RFID antenna 2, rfid interrogator 3 and application system 4; Described RFID antenna 2 is carried out reading process to described RFID label tag 1 and is carried out information transmission to described rfid interrogator 3, after the 3 pairs of information acquisition decodings of described rfid interrogator, information is sent to described application system 4.
In embodiment 1, RFID label tag 1 is embedded on each medicine and reagent pipe of Medical refrigerator, and RFID antenna 2 is distributed in the read-write panel be arranged in below each Reagent Tube, RFID antenna 2 forms the intensive aerial array of 10*10, the central point spacing of horizontal and vertical two adjacent RFID antenna 2 is 11mm, and RFID antenna 2 is uniformly distributed in the plane of writable area panel.Realize the information to each medicine and reagent in Medical refrigerator.
But the environment of Medical refrigerator is special, the array that RFID antenna 2 is formed is too intensive, if use the rfid interrogator 3 of general technology to read, such problem will be produced: the transmission range of signal of RFID antenna 2 must cover other adjacent RFID antenna 2, even if control to work when two adjacent R FID antennas 2 are different, the coil of adjacent R FID antenna 2 also can produce inductive reaction to aerial signal, thus causes cross jamming to the signal of the RFID antenna 2 of duty.
For avoiding producing the problems referred to above, described rfid interrogator comprises detecting circuit 31, amplifying circuit 32, filtering circuit 34 and analog to digital converter 35.
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 3 of the present utility model comprises: detecting circuit 31, amplifying circuit 32, filtering circuit 34 and analog-to-digital conversion device 35.
The difference of prior art and rfid interrogator of the present utility model is:
In prior art, rfid interrogator is as follows to gathered RFID label tag response signal processing mode: carrier wave, by detecting circuit 31, is removed by the carrier signal first RFID label tag 1 read; Then, the signal unloading ripple is amplified through amplifying circuit 32; Then, be mingled with the tag response signal of noise by comparator circuit 33 by after amplification, the value as input voltage is little compared with fiducial value, and output valve is 1, otherwise output valve is 0, and so far, the response signal of RFID label tag 1 is detected.
And the processing scheme of rfid interrogator of the present utility model 3 pairs of RFID response signals 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 amplifying 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 the technical solution of the utility model 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 RFID label tag response signal; Effectively prevent the cross jamming of adjacent antenna.
The above, it is only a certain item embodiment of the present utility model, the present invention is not limited to the restriction of above-described embodiment, all above-described embodiment is done according to technical spirit of the present invention similar amendment, change and replacement, still belong in the scope of technical scheme of the present invention.Protection scope of the present invention is only defined by claims.
