In this embodiment, the preset serial number divides all serial numbers into two parts, wherein one part is the serial number associated with the preset serial number, and the other part is the serial number not associated with the preset serial number. The serial number to be detected is matched with the preset serial number, the relevance between the serial number to be detected and the preset serial number is indicated, and the serial number to be detected belongs to the serial number relevant to the preset serial number. Therefore, the serial numbers needing to be inquired and compared only have serial numbers associated with the preset serial numbers, and the serial numbers not associated with the preset serial numbers do not need to be compared with the serial numbers to be detected, so that the inquiry and comparison times of the serial numbers to be detected improve the data processing speed of the serial numbers of the access cards, and the response speed of the access cards is improved.

In the above embodiment, the serial number is divided into two serial numbers, namely, a normal serial number and an abnormal serial number, that is, the normal serial number belongs to the serial numbers in the white list, and the query comparison result is the serial number in the access card which is used by most users and allowed to pass; and the abnormal serial number belongs to the serial numbers in the blacklist, the query comparison result is forbidden, and a small part of serial numbers in the forbidden cards are forbidden to pass. Because the quantity of normal serial numbers is more, adopt the mode of unusual serial number as the judgement condition, make the inquiry of the serial number that awaits measuring is compared the number of times and is reduced, has improved the data processing speed to the serial number of access control card to the response speed of access control card has been improved, and in addition, the unusual serial number that uses the quantity less for the quantity of the serial number that the storage was judged the condition reduces, thereby further reduces the number of times is compared in the inquiry of the serial number that awaits measuring, has further improved the data processing speed to the serial number of access control card, thereby further improved the response speed of access control card.

In one embodiment, the obtaining serial numbers sequentially arranged according to a preset rule according to each serial number includes: respectively acquiring corresponding pre-recorded serial numbers according to the serial numbers; detecting whether the difference value of any two adjacent pre-recorded serial numbers is matched with a preset difference value or not; and when the difference value of any two adjacent pre-recorded serial numbers is matched with a preset difference value, setting the pre-recorded serial numbers as serial numbers corresponding to the serial numbers. In this embodiment, to each before the entrance guard's card authorizes, this moment storage area in the entrance guard's card is the serial number that has not yet corresponded, moreover, because the serial number of entrance guard's card is unordered, different serial numbers need compare with the serial number on the entrance guard's card that awaits measuring one by one. In the access control card management device, corresponding pre-recorded serial numbers are respectively obtained according to the serial numbers, wherein the pre-recorded serial numbers are self-defined numerical values, and each access control card corresponds to a temporary pre-recorded serial number when authorized.

In one embodiment, an access card management device is implemented by using the access card management method described in any one of the above embodiments. In one embodiment, the access control card management device is provided with a functional module for realizing the access control card management method corresponding to each step. In one embodiment, as shown in fig. 2, there is provided an access card management apparatus 10, including a reading module 100, a writing module 200, and a processing module 300, where: the reading module 100 is configured to obtain a serial number of each access card; the reading module 100 is further configured to obtain a serial number to be detected; the processing module 300 is configured to obtain serial numbers sequentially arranged according to a preset rule according to each serial number; the processing module 300 is further configured to detect whether the serial number to be detected matches a preset serial number; the processing module 300 is further configured to, when the serial number to be detected matches the preset serial number, sequentially compare the serial number matching the preset serial number with the serial number to be detected; the writing module 200 is used for writing the serial number into the corresponding storage area of the access control card. In one embodiment, the reading module 100 includes a card reader, and the reading module 100 is configured to read a serial number of an access card and a serial number to be tested.

In one embodiment, the reading module 100 is configured to obtain a serial number of each access card. The serial number of entrance guard's card is the number that each entrance guard's card is unique, and the serial number on each entrance guard's card all is different, does not have the entrance guard's card of the same serial number promptly. Because the uniqueness of the serial number of the access card, the entry of the serial number of each access card only needs once, namely, the entry operation of the serial number is completed once by the reading module 100, and the corresponding serial number of the access card can be stored in the access card device without considering the occurrence of repeated serial numbers. Moreover, the serial number is stored in a database by the read module 100, and the database containing the serial number may be independent of the read module 100, i.e. the size of the serial number does not affect the memory size of the read module 100. In one embodiment, the serial number of the access card is acquired from a database through a wireless transmission system, and the database containing the serial number is a database in a server in a background. Moreover, the serial number is only used when the access card is authorized and revoked, for example, when the access card needs to be authorized, the reading module 100 respectively transmits the serial number to the database and the processing module 300, the serial number is stored in the database, the processing module 300 obtains the serial number corresponding to the serial number according to the serial number, and the processing module 300 transmits the corresponding relationship between the serial number and the serial number to the database for storage, that is, the database includes the serial number and the corresponding relationship between the serial number and the serial number; when the access control card needs to be cancelled, the access control card management device inquires a corresponding serial number in a database according to the acquired serial number, so that the serial number of the access control card needing to be cancelled is determined, and the access control card is convenient to cancel from the database. Thus, when the access control card is initialized, that is, before no access control card is recorded into the database, the reading module 100 is convenient to determine the number of the access control cards through the obtained serial number of the access control card, and is convenient to subsequently distribute the serial numbers which correspond to and are orderly arranged into different access control cards. In one embodiment, the serial number of the access card is a 32-bit serial number of the Mifare 1 card, and the serial numbers of each batch of Mifare 1 cards are not necessarily continuous, that is, the serial numbers of each batch of Mifare 1 cards have no rule to follow.

In one embodiment, the processing module 300 is configured to obtain serial numbers sequentially arranged according to a preset rule according to each serial number, and write the serial numbers into a corresponding storage area of the access cards, where the serial number of each access card corresponds to one serial number.

The processing module 300 can obtain the corresponding access card according to the obtained serial number, and due to the fact that the serial number of the access card is in disordered arrangement, when the serial number is used as a standard for query comparison, all the entered serial numbers need to be compared, and the number of the compared serial numbers is too large. In order to solve the above problem, the serial numbers that are arranged in an unordered manner are arranged in an ordered manner, and the processing module 300 obtains the serial numbers that are arranged in an ordered manner according to a preset rule according to each serial number, which indicates that the processing module 300 arranges the unordered serial numbers according to a certain rule, each serial number corresponds to one serial number, and all the serial numbers are arranged in a regular and ordered manner. Like this, carry out the permutation in order according to certain law at all serial numbers, no matter what serial number corresponds is which serial number, as long as guarantee the serial number with serial number one-to-one can carry out reordering to unordered serial number, makes the serial number by the serial number replaces to make unordered serial number arrange with orderly mode, be convenient for follow-up only need compare partial serial number when inquiring to the serial number that awaits measuring, thereby be convenient for follow-up comparison number of times of in-process of comparing, improved the data processing speed to the serial number of access card, thereby improved the response speed of access card. In other embodiments, the serial number and the serial number are stored in different components, for example, the serial number and the one-to-one correspondence relationship between the serial number and the serial number are stored in an external database, the serial number is stored in a storage area of the access card, and an abnormal serial number for comparing with the serial number to be detected is stored in the card reader, wherein, because the number of used access cards is large, the number of compared serial numbers is large, in order to reduce the occupancy rate of the memory space of the card reader, the number of used serial numbers which cannot be compared by query is relatively small, that is, the abnormal serial number is used as a judgment standard, and the number of times of query and comparison is further reduced, so as to further improve the data processing speed of the serial number of the access card, thereby further improving the response speed of the access control card.
