The flow chart of the method has the following steps: Step S201: When the access control machine senses the access card, the step S202: the access control machine reads the information of the identification information column of the access card, which includes the unique serial number of the access card and the key reading and identification. The number of times of the information and the number of credits on the number of times of card swiping, first determine whether the format and content are correct access cards; step S203: the access control machine compares the card blacklist, if the card is blacklisted, the access control machine writes back the access card The content of the identification information bar is such that the access control card cannot be used; step S204: if the access control card does not conform to the blacklist of the card, the access control machine will read the key in the identification information and perform the value on the number of times of card swiping, and then return Write to the card number field of the access card, and open the door; Step S205: The access control device updates the card card information, including the card swipe time and the access control number, and returns to the database of the access control management module for storage; step S206: access control mode The group performs abnormality detection; step S207: reading each card information with the same identification code in the database, according to the order of the time of the card, the comparison first The value of the last two card number fields is compared. Step S208: If the value of the number of times of card swiping is regularly accumulated, it represents a normal access card. If the number of times of card swiping is irregularly accumulated, it is determined that there is illegal access control. Card; and step S209: generating a blacklist of cards and downloading them to the access control machine. When the blacklist card with the identification information bar is read and recognized by the access control machine next time, the access control list of the blacklist of the card will be written back to delete the card identification. The contents of the field make it unusable.
其中數值比對係依據邏輯如下:d=a(n)-a(n-1); 其中a(n)代表後一筆刷卡次數值,a(n-1)代表前一筆刷卡次數值,n=1,2,3,4...至最新一筆,a(0)為發卡時的初始值;當d=常數(>0),代表僅有一張卡片正常使用;以及當d=0或負數,代表有多張相同識別碼的卡片在使用,為一非法的門禁卡。 The numerical comparison is based on the following logic: d=a(n)-a(n-1); Where a(n) represents the value of the subsequent number of credits, a(n-1) represents the previous number of credits, n=1, 2, 3, 4... to the latest, a(0) is the initial at the time of card issuance Value; when d=constant (>0), it means that only one card is used normally; and when d=0 or negative number, it means that there are multiple cards with the same identification code in use, which is an illegal access card.
其中門禁卡被門禁機讀取的內容,包含卡片唯一序號及用密鑰讀取識別資訊;其中以密鑰讀取識別資訊區的某一欄位,被當作刷卡次數儲存欄位。 The content of the access card read by the access control machine includes the unique serial number of the card and the identification information read by the key; wherein a certain field of the identification information area is read by the key, and is used as a card storage time field.
