Fig. 1 is the flow chart of IC card management method embodiment one of the present invention, the IC card management method of the embodiment include with
Lower step:
S10. as user in card reader when brush IC card, the first brush that card reader reads the card number of the IC card and stored
Card record, and the record of swiping the card of the card number of the IC card and first is sent to access controller；
In this step, the first memory space for swiping the card record is provided in IC card, which can store N item and swipe the card
Record.User swipe the card every time open the door when, all current charge time can be written the first of IC card and swiped the card in record.In addition, working as
When user card punching, what card reader can read the card number of the IC card and its be stored first swipes the card record, and then card reader will
The card number and the first record of swiping the card are sent to access controller；
S20. access controller according to received card number from multiple IC card that itself is stored swipe the card record in obtain
Second swipes the card record corresponding to the IC card, and the charge time that described second swipes the card in record the latest is determined as joining
Examine the time；
In this step, since each user is when swiping the card, current charge time is in addition to the first brush in write-in IC card
Card record is outer, can also be sent to access controller and be stored, so, access controller is just stored with the IC card of multiple users
It swipes the card record.When the card number of IC card transmitted by access controller receives card reader and its first swipe the card record when, just from from
Second is transferred out corresponding to the IC card in what body was stored swipe the card record to swipe the card record, and second is swiped the card record in the latest
One charge time is as reference time TC.
S30. access controller by the reference time and institute received first swipe the card record in charge time one by one into
Row compares, and judges whether the reference time is later than described first and swipes the card all charge times in recording, if so, holding
Row step S40；If it is not, thening follow the steps S50；
S40. alarm signal is exported；
S50. door open command is issued.
In step S30 into step S50, according to comparison result, it is possible that following three kinds of situations:
(1) if, first swipe the card record in chronological sequence sequence successively are as follows: TI1, TI2, TI3, TI4, TI5, TI6, second
Swipe the card record are as follows: TI1, TI2, TI3, TI4, TI5, TI6, i.e., first swipe the card record swipe the card with second record recorded in swipe the card
Time is identical.The charge time that second, which swipes the card, in recording the latest is TI6, so, TI6 is confirmed as reference time TC.It is logical
Cross and compare and can obtain, reference time TC (TI6) with first swipe the card record in one of them charge time it is identical, that is, there is no evening
Swipe the card all charge times in record in first, at this point, then can " temporary " think that the IC card for legal card, and then executes step
Rapid S50.
(2) if, first swipe the card record are as follows: TI1, TI2, TI3, TI4, second swipes the card record are as follows: TI1, TI2, TI3, TI4,
TI5, TI6, the charge time that second, which swipes the card, in recording the latest are TI6, so, TI6 is confirmed as reference time TC.By comparing
It can obtain, reference time TC (TI6) is later than first and swipes the card all charge times in recording, and has replicated at this point, can confirm
Card, and then executable step S40.Copy card is likely to be this IC card, it is also possible to be that other IC card (such as are working as lawless people
In the case where swiping the card after duplication IC card earlier than legal card)；
(3) if, first swipe the card record are as follows: TI1, TI2, TI3, TI4, TI5, TI6, second swipes the card record are as follows: TI1, TI2,
TI3, TI4, TI5, it is because card reader is controlled to gate inhibition that second, which swipes the card, which records record of swiping the card compared to first to lack charge time TI6,
Communication goes wrong when device processed sends TI6, and there is no successfully store charge time TI6 for access controller.In this case, institute is true
The reference time TC recognized be TI5, can obtain by comparing, reference time TC (TI5) be not later than first swipe the card record in institute
Some charge times, at this point, then can " temporary " think the IC card be legal card, and then execute step S50.
Finally it should be noted that, it is so-called it is " temporary " think the IC card be legal card, be as it is possible that being following feelings
Condition: swiping the card immediately after lawless people replicates IC card, due to being swiped the card earlier than legal card, so system can miss the copy card
Think into legal card.In this case, when legal card is swiped the card again, since what access controller was stored second swipes the card note
Record is swiped the card the record for having recorded a charge time more than the first of legal IC card, so duplication can be mistakenly considered into the legal card
The user for blocking, and then exporting alarm signal, and working as the legal card knows that the IC card of oneself is obviously legal card, but produces report
It is alert, so that it may to know that certain someone replicates the IC card of oneself, and then related personnel can be looked for handle.
The technical solution for implementing the embodiment can all swipe the card to first stored in IC card when by each user card punching
It records and is compared with the second record of swiping the card stored in access controller, therefore, it can be ensured that no matter an IC card is replicated
How many times, only one can effectively use.Multiple cards are replicated if it is user oneself, the more people of card is cannot achieve and replicates use
Purpose；If it is by other people bootleggings, user also can quickly have found the case where card is replicated, and then can contact relevant people
Member carries out crash handling to copy card.
On the basis of the above embodiments, further, between step S10 and step S20, further includes:
S60. access controller judge institute received first swipe the card record whether be it is empty, if so, confirming that the IC card is
Then legal card executes step S50；If it is not, thening follow the steps S20.
In this embodiment, if judging, first swipes the card and is recorded as sky, illustrates that the IC card is that platform operator passes through
Card sender or card reader license to the card of user, are legal cards, so, step S50 can be performed；If judging, first swipes the card note
Record is not sky, and step S20 can be performed.
In practical applications, it sometimes appear that the case where user frequently swipes the card, for example, when user card punching, if card reader with
The communication of access controller is just gone wrong, and brushing card data can not successfully be sent to access controller, so access controller
It is just unable to control enabling, user may swipe the card again at this time, if Communication does not solve, door not opened still, such as these
Deng the case where frequently swiping the card there have been user.In this case, first can swiping the card, to be divided at least two different for record
Classification, and each classification corresponds to corresponding interval, for example, being divided into two class of A, B, wherein the corresponding interval of A class is big
In 2 minutes, the corresponding interval of B class was 0-2 minutes.Moreover, after the step S10 of above-described embodiment, further includes:
S70. current charge time is obtained, and calculate the current charge time to swipe the card in record the latest with described first
The difference of one charge time；
S80. the interval according to corresponding to each classification determines classification corresponding to the difference；
S90. by the current charge time be written described first swipe the card record in respective classes in.
In this embodiment, by reaching just being written in the record that such is distributed for certain class record standard, so, when
When user frequently swipes the card, current charge time can only be written first swipe the card record B class in, first can't be occupied and swiped the card record
The memory space of middle A class.
Still further, the step S90 of above-described embodiment are as follows:
Judge described first swipe the card record respective classes space whether write it is full, if so, being recycled according to time order and function
Described first is covered to swipe the card charge time for having been written into record.
In this step, when N item record has write full in IC card, circulation covering is carried out according to time order and function, it can be ensured that N
