Abstract
The invention discloses an RFID (radio frequency identification) multi-card-in-one integration method, and belongs to the technical field of wireless communication. According to the RFID multi-card-in-one integration method, an RFID card integrated with multiple UIDs (unique identifiers) is included and comprises a read-write unit for an RFID label and a control unit for operating the related RFID label; a high-capacity data memory is used as an information storage medium for the RFID card, and RFID information to be integrated is stored in the memory according to a linear address; the data format in each piece of information in the memory is organized according to an RFID protocol of an ISO standard, namely each piece of data in the memory is an independent RFID card; when the integrated RFID card gets close to a certain card reader, the card reader sends an inquiry instruction.
Description
Technical field
The present invention relates to RFID multi-use card method, belong to wireless communication technology field.
Background technology
Radio-frequency (RF) identification and RFID(Radio Frequency IDentification) technology, also known as electronic tag, radio frequency identification, it is a kind of communication technology, read and write related data by radio signals identification specific objective, and without the need to setting up machinery or optical contact between recognition system and specific objective.
Existing rfid system all uses iso standard agreement (as ISO-14443), and the different card-reading apparatus that different manufacturers is produced communicates mutually.But there is a lot of drawback based on the RFID card-reading system of above-mentioned technology.First, different system uses different RFID label tag, when someone has the rfid card of some, can bring inconvenience to holder.Secondly, not association between rfid card, which results in RFID label tag data in the staff that holds and forms information island.
Summary of the invention
In order to overcome above-mentioned deficiency, the object of the invention is to drawings RFID multi-use card method.
The present invention takes following technical scheme:
RFID multi-use card method, comprises the rfid card of integrated multiple UID, comprises the read-write cell of RFID label tag and the control module for performing the control relating to described RFID label tag, with the information storage medium of jumbo data-carrier store as rfid card, and will integrated RFID information be needed linearly to store in memory address, in storer, the data layout of every bar information inside is all according to the RFID protocol tissue of iso standard, namely in storer, every bar data are all independently rfid cards, when integrated rfid card is near certain card reader, card reader sends inquiry instruction, rfid card returns the UID of every bar record in storer after receiving inquiry instruction, at this moment card reader distinguishes different information by anti-collision algorithms, when card reader sends reading request of data again, integrated card returns the data of needs according to the UID that card reader is specified, described storer is not can access completely for each card reader, needs checking during card reader Card Reader, and after card checking, card reader can only read granted access region.
Specific RFID label tag read-write algorithm is: when card reader reads unification card, all UID in unification card output card, card reader reads one of them UID by anti-collision algorithms, whether card reader checking UID belongs to this system, if do not belong to, continue through anti-collision algorithms and read next UID, until find the UID needing communication card; After finding UID, card reader sends selection instruction, selects UID, shields the communication of other card, until power on next time after unification card receives the selection instruction of card reader; After card reader selects UID, unification card presents single deck tape-recorder state to card reader, until power on next time.
Beneficial aspects of the present invention: unified rfid card, efficiently solves the problem that multiple rfid card data exist information island, retain the independence between different information simultaneously, make data security reliable.
Accompanying drawing explanation
Fig. 1 is that RFID integrated card of the present invention stores schematic diagram;
Fig. 2 is RFID integrated card communication process schematic diagram of the present invention.
Embodiment
Fig. 1: shown in.Integrated rfid card of the present invention uses jumbo storer to store the information of multiple card, and Fig. 1 is the data structure that the many cards of memory inside store.Specify according in RFID protocol, each rfid card has a unique mark UID, and the data space of certain length, and multiple said structure is integrated in a rfid card by integrated rfid card of the present invention, each card information as a record, as shown in Figure 1.
Communication process is as Fig. 2, when integrated card enters the Card Reader region of card reader, after receiving inquiry instruction, whole UID in card send by integrated card, card reader selects corresponding rfid card, and sends checking request, and after card receives checking request, whether this card reader of verification has the right operation sheet, if be verified, send mandate, after card reader mandate, read-write operation can be carried out to rfid card appointed area.
Comprising the rfid card of integrated multiple UID, comprising the read-write cell of RFID label tag and the control module for performing the control relating to described RFID label tag, with the information storage medium of jumbo data-carrier store as rfid card, and will integrated RFID information be needed linearly to store in memory address, in storer, the data layout of every bar information inside is all according to the RFID protocol tissue of iso standard, namely in storer, every bar data are all independently rfid cards, when integrated rfid card is near certain card reader, card reader sends inquiry instruction, rfid card returns the UID of every bar record in storer after receiving inquiry instruction, at this moment card reader distinguishes different information by anti-collision algorithms, when card reader sends reading request of data again, integrated card returns the data of needs according to the UID that card reader is specified, described storer is not can access completely for each card reader, needs checking during card reader Card Reader, and after card checking, card reader can only read granted access region.
Specific RFID label tag read-write algorithm is: when card reader reads unification card, all UID in unification card output card, card reader reads one of them UID by anti-collision algorithms, whether card reader checking UID belongs to this system, if do not belong to, continue through anti-collision algorithms and read next UID, until find the UID needing communication card; After finding UID, card reader sends selection instruction, selects UID, shields the communication of other card, until power on next time after unification card receives the selection instruction of card reader; After card reader selects UID, unification card presents single deck tape-recorder state to card reader, until power on next time.
