BEST MODE FOR CARRYING OUT THE INVENTION

[0046] The IC card management method of the present invention can be applied to an access control system. First, the access control system includes a platform end, a device end, and a user end, and the platform end includes an access control server and a workstation; and the device end includes an access control controller (or It is: access control main controller + access control sub-controller), card reader and card issuer; client is IC card. Moreover, the platform operator issues the card authorization to the user through the card issuing machine or the card reader. When the user swipes the card on the authorized door, the card reader writes a card record to the sector of the IC card, and also to the door. The controller is forbidden to transmit the same record, and the access controller saves this record. N card records can be stored in the IC card. For newly issued IC cards, N credit card records are empty. Of course, when the N card records are full, the original card record can be cleared by the card issuing machine. The access controller can store the credit card records of multiple IC cards, personnel and card data, authorization data, and sub-device data, and determine the calibration of the card reader.

1 is a flowchart of Embodiment 1 of an IC card management method according to the present invention. The IC card management method of the embodiment includes the following steps:

[0048] S10. When the user swipes the IC card on the card reader, the card reader reads the card number of the IC card and the stored first card record, and sends the card number of the IC card and the first card record. To the access controller;

[0049] In this step, the IC card is provided with a storage space of the first credit card record, and the storage space can store N credit card records. Each time the user swipes the door, the current card is written to the first card record of the IC card. In addition, when the user swipes the card, the card reader can read the card number of the IC card and the stored first card record, and then the card reader sends the card number and the first card record to the access controller;

[0050] S20. The access controller acquires the second card record corresponding to the IC card from the card record of the plurality of IC cards stored by itself according to the received card number, and records the second card record at the latest. One of the cards is determined as a reference time;

[0051] In this step, since each user is swiping, the current swipe card is sent to the access controller for storage in addition to the first swipe record in the IC card, so the access controller is A credit card record of an IC card storing a plurality of users. When the access controller receives the card number of the IC card sent by the card reader and the first card record record, the second card record corresponding to the IC card is retrieved from the card record stored by itself, and the The latest one in the second card record is used as the reference daytime TC.

[0052] S30. The access controller compares the reference time between the reference cards in the received first card record, and determines whether the reference time is later than any of the first card records. a swipe, if yes, step S40; if no, step S50;

[0053] S40. outputting an alarm signal;

[0054] S50. Issue a trick instruction.

[0055] In steps S30 to S50, according to the comparison result, the following three situations may occur:

[0056] (1) If the first card record is in the order of: TI1, ΤΙ2, ΤΙ3, ΤΙ4, ΤΙ5, ΤΙ6, the second card record is: ΤΙ1, ΤΙ2, ΤΙ3, ΤΙ4, ΤΙ5, ΤΙ6, That is, the first card record and the first The swipes recorded in the second swipe record are identical. The latest card swipe in the second swipe record is TI 6, so TI6 is confirmed as the reference diurnal TC. By comparison, the reference day TC (TI6) is the same as one of the first swipe records, that is, no later than any of the first swipe records, this can be " Temporarily, "the IC card is considered to be a legitimate card, and then step S50 is performed.

[0057] (2) If the first card record is: ΤΠ, ΤΙ2, ΤΙ3, ΤΙ4, the second card record is: TI1, TI2, ΤΙ3, ΤΙ4, ΤΙ5, ΤΙ6, the latest card in the second card record吋6 is ,6, so ΤΙ6 is confirmed as the reference 吋TC. By comparison, the reference day TC (TI6) is later than any of the first card records in the first card record, and then the copy card can be confirmed, and step S40 can be performed. The copy card may be this IC card, or it may be another IC card (for example, when the unlawful person copies the IC card before the legal card is swiped);

[0058] (3) If the first card record is: ΤΠ, ΤΙ2, ΤΙ3, ΤΙ4, ΤΙ5, ΤΙ6, the second card record is: ΤΙ1, ΤΙ2, ΤΙ3, ΤΙ4, ΤΙ5, the second card record is compared with the first Swipe records are missing the card 吋

16 is because the card reader has a problem communicating to the access controller, and the access controller has not successfully stored the card 吋6. In this case, the confirmed reference diurnal TC is ΤΙ5. By comparison, the reference diurnal TC (ΤΙ5) is not later than any of the first swipe records in the first swipe record.吋 "The IC card is considered to be a legitimate card, and step S50 is performed.

[0059] Finally, it should be noted that the so-called "temporary" considers the IC card to be a legitimate card because it may be the following: When the unlawful person copies the IC card, the card is swiped immediately, because it is earlier than the legal card. , so the system will mistake the copy card for a legitimate card. In this case, when the legal card is swiped again, since the second swipe record stored by the access controller is more than the first swipe record of the legal IC card, the legal card is mistakenly considered. The card is copied, and then the alarm signal is output. When the user of the legal card knows that his IC card is a legitimate card, an alarm is generated, and it is known that someone must copy their own IC card, and then the relevant personnel can be processed. .

[0060] The technical solution of the embodiment is implemented, because each time the user swipes the card, the first card record stored in the IC card is compared with the second card record stored in the access controller, thereby ensuring a No matter how many times an IC card is copied, only one can be used effectively. If the user copies multiple cards by himself, the purpose of copying and using one card cannot be realized; if it is illegally copied by others, the user can quickly find out that the card is copied, and then the relevant personnel can be contacted to invalidate the copy card. deal with. [0061] On the basis of the foregoing embodiment, further, between step S10 and step S20, the method further includes:

[0062] S60. The access controller determines whether the received first card record is empty, and if yes, confirms that the IC card is a valid card, and then performs step S50; if not, step S20 is performed.

[0063] In this embodiment, if it is determined that the first card record is empty, it indicates that the IC card is a card authorized by the platform operator to the user through the card issuing machine or the card reader, and is a legal card, so, the executable steps are performed. S50. If it is determined that the first card record is not empty, step S20 may be performed.

[0064] In practical applications, there may be cases where the user frequently swipes the card. For example, if the user swipes the card, if the communication between the card reader and the access controller is just a problem, the card data cannot be successfully transmitted to the access controller, so The access controller can't control the trick, so the user may swipe the card again. If the communication problem is not solved, the door can't be locked, and so on, the user frequently swipes the card. In this case, the first card record can be divided into at least two different categories, and each category corresponds to a corresponding interval range, for example, divided into two categories, A and B, wherein the interval corresponding to the class A is greater than For 2 minutes, the class B corresponds to an interval of 0-2 minutes. Moreover, after step S10 of the above embodiment, the method further includes:

[0065] S70. Acquire a current swipe, and calculate a difference between the current swipe and the latest one of the first swipe records;

[0066] S80. Determine a category corresponding to the difference according to an interval range corresponding to each category;

[0067] S90. Write the current swipe card into a corresponding category in the first swipe record.

[0068] In this embodiment, since a certain type of recording standard is written into the recorded record of the class, when the user frequently swipes the card, only the first swipe record is written to the current swipe. In the class, it does not occupy the storage space of class A in the first card record.

Further, step S90 of the above embodiment is:

[0070] determining whether the space of the corresponding category of the first swipe record is full, and if so, overwriting the swipes that have been written in the first swipe record in a loop.

[0071] In this step, when the N records in the IC card have been filled, the loop coverage is performed successively according to the time interval, so that N records are ensured to be the latest recording time.
