[b]Metal access control principle[/b]
How does the [url=http://www.pc15.net/view_4342.html]metal access control[/url] keyboard work? First of all, we need to understand it. It is an access control integrated machine with a keyboard. Generally, it emits electromagnetic waves at a fixed frequency. The frequency is 13.56MHz. When the RFID proximity card enters the vicinity of the metal access control, it will trigger the coil on the induction card. The current and the antenna that triggers the proximity card emit a signal to the reader.
[b]Metal access control workflow[/b]
When the RFID proximity card is held into the working area of the reader, the reader of the metal access keypad recognizes the RFID tag, and the host authenticates and judges the identity of the tag. If the result is true, then the internal core control of the metal access control keyboard is A command to open the door is sent to the relay, and the energization of the relay causes the magnetic lock device to pull in and open the door lock.

When the internal access control of the metal access control keyboard is false, the person entering the door is judged to be an illegal user. At this time, the host will issue an erroneous alarm sound. If the device is subjected to human violence, the metal access control keypad will be triggered to issue an alarm control. The command, which drives the language prompt, sends the information of the cardholder illegally entering the access control to the host, so that the administrator can understand the situation in the first time and facilitate the processing.

[b]Identification mode of metal access control keyboard[/b]
Mode 1: Unidirectional sensing mode

The user uses an authorized proximity card outside the door to perform the unlocking task after confirming the legal identity through the metal access keypad.

Mode 2: Two-way sensing mode

The user uses an authorized proximity card outside the door to identify the identity through the metal access control keypad. The controller driver turns on the electric lock and releases the user. The user also needs to present the authorized proximity card. After the metal access control keyboard is recognized, the lock is unlocked. .

Mode 3: Card + Password Mode

After the user swipes the card, the user needs to enter the correct password on the metal access control keyboard to perform the unlocking task. The password can be a personalized password. This advantage is applied to situations where the security level is higher.

Mode 4: Card Number + Password Mode

The user can verify the opening of the door by entering the correct card number and password on the metal access keypad in the format of "*card number*password#". This mode can be used if you forget to bring a card. (This type of door opening method varies from device to device)

The work of the metal access control keyboard is not difficult to understand. It is only necessary for the user to open the door according to the correct operation method.[/url]
