In access control applications, the use of traditional metal key door locks, although the cost is low, but the opening key is easy to be copied, lost, rusted, etc., and inconvenient to carry and other shortcomings, it is far from meeting the requirements of modern building security. The high-end commercial buildings with beautiful environment require more advanced and high-end door locks, and pursue smart management methods. In this way, a new type of “proximity card smart access control system” has won people’s trust with its brand-new use concept, and has quickly gained popularity. Application, the system organically combines the “induction card” and the “lock”, and then replaces the “key” with the “induction card”, and cooperates with the computer software to realize the remote real-time management of the center, realizes the highly intelligent access control, and effectively solves the problem of traditional door locks. Many deficiencies, and its excellent management and use functions bring unexpected convenience to people.
Especially for some confidential archives, central computer rooms, cultural relic storage rooms, and safe passages of financial industry business points with higher security requirements, these places usually store extremely high economic value or extremely important and confidential items, except Except for certain staff, ordinary people are not allowed to enter. However, these “profitable” places can easily become the targets of criminals. Therefore, it is particularly important to build an access control system with extremely high security. In this way, an advanced security application special case of the building sensor card intelligent access control system-AB door double-door interlocking access control system came into being.
The smart card AB door double-door interlocking access control is a very ingenious application of the smart access control system. It is necessary to install a double-door interlocking access control on a passage that needs to strictly control the entry and exit of personnel. When people pass, they must pass the first door. The second door can be opened after closing the door. This effectively isolates the space on both sides of the passage and prevents criminals from trailing into the safe area. The double-door interlocking system can also be used with closed-circuit monitoring equipment to realize the center’s monitoring of card-swiping personnel, and it can also install a fingerprint scanner to achieve more advanced fingerprint AB door double-door interlocking access control.

Note: The system can be linked to the closed-circuit monitoring system to realize the function of swiping the card to capture images. When a person swipes a card at the card reader, the system software will take a real-time screenshot of the corresponding camera monitoring screen and store it in the database together with the card swiping record for query. The system software interface can monitor the access control point in real time.
System function introduction
1. System features
First, explain the concept of double-door interlocking of AB door. The so-called double-door interlocking linkage means that the two doors of AB have the function of interlocking linkage, that is, when one door is opened, the other door will not open, only when both doors are open. Only when it is closed can any of the doors be opened. In the application of access control in high-security places, after entering the first door, a certain person must lock the first door according to the operation requirements before entering the second door. If the first door is not closed as required after entering the first door, the Can not enter the second door, the purpose of this is to prevent criminals from stalking the crime.
According to the requirements of different places, this system can be extended to multi-door interlocking access control with ABC three doors and more doors to achieve higher level of security requirements. It can also cooperate with the central remote control to realize the AB interlocking double door access control combining the local confirmation door opening and the central remote opening door. The features of the system are as follows:
●Double door interlock function
When any door is controlled and needs to be opened, the other door is absolutely prohibited from being opened, and it has the function of automatic anti-following-in. For special places, multi-door interlocking with more than 3 doors can also be realized.
●Emergency door closure and alarm function
When an alarm occurs, the door can be closed urgently through the management software. Two doors can be forcibly closed at the same time, so that both inside and outside the door cannot be opened, guarding the enemy outside the door or imprisoning criminals between the two doors, and at the same time reporting to the public security organs or relevant personnel.
●Alarm linkage function
When other parts of the alarm system have an alarm signal, the two doors are forcibly closed at the same time. It can be linked with the closed-circuit monitoring system. When the system alarms, the controller outputs an alarm signal to the closed-circuit monitoring hard disk video recorder or matrix machine to start the corresponding camera.
●Multiple identification systems
The system controller supports non-contact IC card recognition, biometric recognition (such as fingerprint recognition, iris recognition, palm recognition, etc.).
●Unclosed door reminder function
When any door is opened for more than the specified time and is not closed or falsely locked, the door will be closed through the on-site buzzer or the alarm of the management host.
●Duress to open the door alarm function
If the cardholder opens the door under duress, just enter the duress password to open the door, and an alarm signal will be issued when the door is opened. It not only guarantees personal safety, but also can report to the police in time.
●Software remote opening function
For those who have no identity to open the door, if they are allowed to enter, they can press the door open button on the management software interface to open the door, but they are limited by the logical relationship of the interlock linkage.
The system can also be set to open the door remotely through the central software during non-working hours: After the staff enters the password or swipes the card, presses the fingerprint, the controller passes the verification but does not open the door, and the management center staff confirms and decides to open the door through the software remotely .
●Intelligent management
Manage the authority, time of entry and exit, and entry method of personnel entering and exiting through the management computer. The management computer can monitor the incoming and outgoing personnel and the corresponding events in real time, and store the corresponding data at the same time for later query.
2. Other functional goals of the system
(1) Replace the mechanical key with a non-contact card, which can only be used with the authorization of the management center;
(2) Management functions such as card issuance, authorization, cancellation, and recycling;
(3) Multiple door opening methods such as card opening, card + password opening, fingerprint opening, etc.;
(4) Anti-duress function: When criminals threaten the card holder to open the door, the card holder can enter the duress code on the card reader password keyboard. At this time, the access control point is normally unlocked, but the controller has unknowingly activated the alarm The signal is transmitted to the management center.
(5) Anti-passback and anti-following function: The system guarantees that one person can open the door with one card, and only swipe in can be swiped out. That is to say, the same card can only be swiped to open the door after swiping the card to enter the door, thus preventing one card. Use by multiple people. At the same time, only one person can pass each time the card is swiped.
(6) Fire linkage alarm to open the door (this function can be set to open or close);
(7) Power is supplied by UPS power supply after power failure, which can support 8-12 hours;
(8) Door opening records are summarized to the computer to generate reports for inquiries;
(9) Image capture and comparison function:
When the user is authorized to issue the card, the user’s photo is stored in the database. When the user swipes the card or presses the fingerprint to open the door, the computer software interface will call up the corresponding photo of the card or fingerprint in real time, and take a snapshot of the corresponding camera monitoring screen. A picture is displayed on the software interface, and the staff on duty can compare them. If they find that they do not match, they can lock the access control through the software for processing.
(10) Automatic alarm:
1) Unauthorized card swiping cannot open the door;
2) The door is opened abnormally/or closed abnormally;
3) The indoor infrared alarm or smoke alarm system will automatically alarm.
