Type information；The RFID reader includes reader, decoder and transmitter, and the RFID reader for reading in real time
The product signal of RFID label tag output, the decoder is for the real-time decoding product signal, generation decoded signal, the transmission
Device is for exporting the decoded signal；The comparator is connect by signal wire with host computer；The first fortune is equipped in the host computer
Calculate unit, backup units, processing unit and Database Unit；The certificate of authority is prestored in first arithmetic element and matching is calculated
Method is used to that decoded signal to be combined to generate First ray code key；The backup units are secret for backing up decoded signal and the first access
Key is simultaneously exported to comparator；The second arithmetic element and comparing unit are equipped in the comparator；It is pre- in second arithmetic element
There are the certificate of authority and matching algorithm, for combining decoded signal to generate the second sequence code key；The comparison operation unit is used for
Comparison operation First ray code key and the second sequence code key, and when the First ray code key is consistent with the second sequence code key pair
Host computer exports feedback signal；The processing unit is when receiving feedback signal, by First ray code key combination decoded signal,
It constitutes product certification and product certification is written in Database Unit.
Preferably, in the above-mentioned communication system based on RFID: further including client；The host computer passes through http protocol
Signal interaction is carried out with client.
It is further preferred that in the above-mentioned communication system based on RFID: the client is using cell phone client and/or PC visitor
Family end.
It may further be preferable that in the above-mentioned communication system based on RFID: leading between the RFID reader and host computer
It crosses http protocol and carries out signal interaction.
Compared with prior art, the comparator that the application can not be accessed by increasing an outer net is based on decoded signal
Two groups of sequence code keys are generated respectively, and ensure that the interpretation to decoded signal is errorless by the comparison of sequence code key, to realize
The promotion of the safety of whole system.
Detailed description of the invention
The utility model is described in further detail with specific embodiment with reference to the accompanying drawing:
Fig. 1 is the system schematic block diagram of the utility model.
Each appended drawing reference and component names corresponding relationship are as follows:
1, RFID label tag；2, RFID reader；3, host computer；
Specific embodiment
In order to illustrate more clearly of the technical solution of the utility model, further retouched below in conjunction with each embodiment
It states.
As shown in Figure 1:
A kind of communication system based on RFID comprising: RFID label tag 1, RFID reader 2,3 comparator of host computer, 4 He
Client 5；The RFID label tag 1 is installed in equipment, is used for real-time output products signal, includes equipment in the product signal
Id information and device type information；The RFID reader 2 includes reader, decoder and transmitter, and the reader is used for
The product signal of RFID label tag output is read in real time, the decoder is used for the real-time decoding product signal, generates decoded signal,
The transmitter is for exporting the decoded signal；
The comparator 4 is connect by signal wire with host computer 3；The first arithmetic element, backup are equipped in the host computer 3
Unit, processing unit and Database Unit；The certificate of authority and matching algorithm are prestored in first arithmetic element, for combining
Decoded signal generates First ray code key；The backup units for back up decoded signal and first access code key and export to than
Compared in comparator 4 described in device 4 be equipped with the second arithmetic element and comparing unit；The certificate of authority is prestored in second arithmetic element
With matching algorithm, for combining decoded signal to generate the second sequence code key；The comparison operation unit is used for comparison operation first
Sequence code key and the second sequence code key, and host computer 3 is exported when the First ray code key is consistent with the second sequence code key
Feedback signal；The processing unit, by First ray code key combination decoded signal, constitutes product card when receiving feedback signal
Simultaneously product certification is written in Database Unit for book.The host computer 3 carries out signal interaction by http protocol and client 5.
Cell phone client and/or pc client can be used in the client 5.Pass through HTTP between the RFID reader 2 and host computer 3
Agreement carries out signal interaction.
In practice, the course of work is as follows:
When the equipment for posting RFID label tag 1 enters in its radio frequency effective range, RFID reader 2 reads RFID label tag in real time
The product signal of 1 output generates decoded signal according to the product signal, and exports the decoded signal to upper by http protocol
Machine 3；The first arithmetic element in host computer 3 passes through the certificate of authority prestored and matching algorithm, generates the in conjunction with the decoded signal
