The accompanying drawings, which are included to provide a further understanding of the disclosure and are incorporated in and constitute a part of this specification, illustrate exemplary embodiments of the disclosure and together with the description serve to explain the principles of the disclosure.
Fig. 1 is a topological diagram of the structure of a multi-type card number verification device according to at least one embodiment of the present disclosure.
Detailed Description
The present disclosure will be described in further detail with reference to the drawings and embodiments. It is to be understood that the specific embodiments described herein are for purposes of illustration only and are not to be construed as limitations of the present disclosure. It should be further noted that, for the convenience of description, only the portions relevant to the present disclosure are shown in the drawings.
It should be noted that the embodiments and features of the embodiments in the present disclosure may be combined with each other without conflict. The present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
In a modern access control system, if a card reader is replaced, because the number of the card numbers read by different card readers is different, the card number information stored by the original server is no longer suitable for a new card reader, and an access control manager needs to re-enter the card number for authorization, thereby bringing huge workload. For example, the card number information digits of the HID card information and the IC information are different, the data personnel stores the HID card format, and the user wants to replace the IC card, which results in that the user authentication cannot realize the door opening.
In at least one embodiment of the disclosure, the disclosure provides a compatible method of a multi-type card number verification device, and when the card reader types are different, the card number compatibility module is used for processing to make the information of the card number compatible module consistent with the database of the original server side. As shown in fig. 1, the multi-type card number verification device comprises a card reader, a card number information compatible module and a server. The method comprises the following steps: the card reader obtains card type parameters and card numbers, sends the card type parameters and the card numbers to the card number information compatible module and the server side, the server side sends the corresponding target card number length to the card number information compatible module according to the card type parameters, and the card number information compatible module converts the card numbers into the target card numbers with the same length as the target card numbers.
The server side comprises a database, the database is used for storing personnel information, and the personnel information comprises door opening permission.
The card number information compatible module is also used for sending the target card number to the server side, and the server side searches the personnel information according to the target card number and obtains the door opening authority of the personnel information. The door opening authority is to allow the door to be opened or forbid the door to be opened. The person information is stored in a hash table.
The server also comprises a hash value calculation module, and the target card number is divided into arrays and sent to the hash value calculation module.
The hash value calculation module calculates the address of the hash table according to the array, and the server side acquires the personnel information stored in the hash table according to the address of the hash table and acquires whether the personnel information has the door opening permission.
The card reader compatible system also includes an access control device and a lock actuator.
The server sends the door opening permission to the access control equipment, and the access control equipment controls the lock execution mechanism to complete corresponding actions according to the door opening permission.
When the door opening authority is allowed to open the door, the lock actuating mechanism completes the door opening action; when the door opening authority is that the door is forbidden to open, the lock execution mechanism keeps the door locked state, sends the reason for forbidding opening the door to the server side, and also can return the reason for forbidding opening the door to the card reader, and informs the card reader that the door cannot be opened through a text display or voice broadcast mode.
The operation of the reader compatible system provided by the present disclosure is described in detail below in a specific preferred embodiment. However, the examples selected are merely illustrative of the present disclosure and do not limit the scope of the present disclosure.
The front-end verification device, namely the card reader, detects card verification information including the card type and the card number, transmits the information to the card number information compatible module, and compares the information with the card type parameter set by the server. The server side tells the verification equipment that the length of the card number is within 4 digits, if the verification equipment actually reads that the card number is 8 digits, the 8 digits are converted into effective 4 digits, the data of the card number is consistent with the card number in the database, and therefore the compatible function of different card reader types is achieved. The server splits the read card number and divides the card number into an array with the length of 4. This array is issued 3 times to the interface CreatHash (uint8 id, uint32dwHashType) that calculates the hash value of the string. And when dwHashType is 0, the calculated hash value is used for determining the position of the character string in the hash table, when dwHashType is 1, when dwHashType is 2, the calculated hash value is used for verifying the character string, the returned character string is used for calculating the address of the hash table, and finally the node value of the hash table of the user is inquired. And reading corresponding personnel information in the hash table according to the node, judging whether the personnel has the door opening authority, if so, executing door opening, if not, forbidding door opening, and reporting the reason for forbidding door opening to the server.
And the server sends a command to the access control equipment to issue an instruction for allowing or forbidding opening the door to the lock execution mechanism according to the verification result.
The compatible method of the multi-type card number verification equipment provided by the disclosure has the compatible function and the card type conversion function of different entrance guard card types. When different card readers are replaced, the entrance guard host dynamically configures the types of different entrance guard cards, starts the compatible function, solves the problem of card number compatibility rules, and card numbers of terminals with different lengths and sizes can be compatible according to the configuration rules. Therefore, after the card reader type is changed, the problem that the user repeatedly inputs the card number again can be solved, and the user experience is improved; the entrance guard does not need to be authorized again, and the entrance guard can be replaced noninductively.
It will be understood by those skilled in the art that the foregoing embodiments are merely for clarity of illustration of the disclosure and are not intended to limit the scope of the disclosure. Other variations or modifications may occur to those skilled in the art, based on the foregoing disclosure, and are still within the scope of the present disclosure.
