System function and structure
Preface
The so-called anti-tailing refers to the interlocking function of two doors. When one door is opened, the other door cannot be opened, and the other door is allowed to be opened only after the first door is closed. Bank robberies usually occur when criminals use violent means to rob the bank’s business halls and vaults by hijacking, forcing bank staff, or directly using blasting and other bad methods, resulting in economic damage to the bank and a serious threat to the bank. Personal safety of employees.To this end, we launchedAnti-tailing access controlThe system is an access control security control system specially developed for criminals who use trailing or coercive methods to enter the business hall to carry out illegal activities.
1. Overview of the bank anti-trailer access control system
1. Bank anti-tailingAccess control systemdemand analysis
• Use computer technology, network communication technology, automatic control technology, and digital image processing technology to conduct strict and scientific management of high-risk locations such as banks and treasuries to improve the image of banks, financial institutions and other enterprises and improve the security level of the entire location .
• Strictly monitor and control certain banks, treasury and other important areas or departments, such as: treasury entrances and exits, business hall entrances and exits, etc.
• Adopt advanced non-contact inductive card reading technology to avoid physical damage to the card caused by multiple insertion of a contact card or inconvenient unlocking with a hardware lock.
• With multiple alarm states, bank employees can trigger alarm events without the gang’s knowledge. Through networking with the management control host, the central controller can collect on-site alarm information in time and deal with them immediately to ensure the personal safety of the bank’s property and employees .
• Conduct unified management of bank employees, requiring all employees to enter the vault or business hall to pass strict identity authentication (by swiping a card or other door opening methods), and the employee’s card swiping record can be used as an attendance record at the same time, which can be statistically analyzed.
2. Design principles of bank anti-trailing access control system
The prerequisite for the design of the bank’s anti-trailing access control system is to meet the various needs of users. Utilize its advanced, mature, reliable, flexible technology and good price-performance ratio to maximize the long-term interests of users and allow users to obtain the greatest return with the smallest investment.
The following are the main design principles of this system:
• Practicability: The function of the bank’s anti-trailing access control system should meet actual needs. It should not be flashy. The one-sided pursuit of the system’s advancement will inevitably lead to excessive investment and inconsistent with actual applications. Therefore, the practicability of the system is the first principle that should be followed.
• Ease of operation: The operation of the front-end products and software of the bank’s anti-trailing access control system is simple and easy to understand, and the general users or operators can operate independently through simple training or provided manuals. Security adopts TCP/IP and RS485 combination networking, which has higher reliability and more stable performance. It has powerful real-time monitoring function, door interlock function and linkage control, etc., to ensure the safety and reliability of the entire system.
• Scalability: Adopting the access control system control technology, when the user’s needs change, it can be easily realized through the powerful functions of the access control. For example, the number of interlocking door points can be flexibly increased or decreased (it is necessary to increase the number of interlocking doors at the same time), to meet different periods and occasions with different functional requirements, through the linkage function to perform more linkage alarm control, etc. Regularly go to the company website to upgrade the latest management software for free to ensure that the system is always in the leading position.
3. Realization of bank anti-tailing access control system
• Interlock linkage function: When any door is open, the opening of the other door is absolutely prohibited, with automatic anti-following-in function. For special places, linkage and interlocking of more than 3 doors can also be realized.
• Two-way card reading function: Two-way card reading can be realized for two doors, that is, both the inner door and the outer door can be used to read cards in and out.
• Unclosed door reminder function: When any door is opened for more than a specified time (0~255 seconds can be set) and is not closed or falsely locked, it will be prompted to close the door through the on-site buzzer or the management host alarm.
• Emergency door lock and alarm function: When an alarm occurs, press the emergency door button in the business room to lock the two doors at the same time, so that both the inside and the outside of the door cannot be opened. Imprisoned between two doors. At the same time, report to the Public Security Bureau or relevant personnel.
• Duress to open the door alarm function: If the cardholder opens the door under the threat of criminals, just use the duress password to open the door. When the door is opened, an alarm signal (alarm or light) will be sent to the monitoring center, which not only ensures personal safety, but also instantly Call the police.
• Alarm linkage function: When there is an alarm signal from other parts of the alarm system, the two doors will be forcibly locked at the same time, making it impossible for the gangster to succeed.
• Button to open the door function: For those who do not have the identity to open the door, if they are allowed to enter, they can press the door open button in the business room (each door corresponds to a button), which can realize convenient door opening, but is limited by the interlock linkage logic relationship .
• Emergency double opening function: When picking up the cash drawer in the morning and evening or in a very emergency situation (such as fire, poisonous gas, etc.), press the emergency door opening button in the business room to open both doors at the same time.
• Intelligent management: It is safe and convenient to manage the authority, time and method of entering and exiting personnel through the management computer. The management computer can monitor the incoming and outgoing personnel and corresponding events in real time, and store the corresponding data at the same time for later query.
• Multiple identification systems: the system supports non-contact IC card identification systems, biometric systems (such as fingerprint recognition, iris recognition, palm recognition, etc.)
• Multi-card door opening function: In important areas, the system can set the multi-card door opening method, that is, when opening a door, multiple people must simultaneously identify the identity within a specified time before the door can be opened. The system can set up 2-8 people.
2. Design of the bank’s anti-trailing access control system
1. The principle of the bank’s anti-trailing access control system
The digital human intelligent anti-following door system is mainly aimed at banks, treasury and other departments in the important links of extracting or storing valuables, and an effective measure to prevent sudden robberies. This system is installed inside the passages of banks and vaults, with a total of two doors.System equipment includes: management software, communicator, field controller, electronic lock system, identification system (such asCard reader) And indoor control buttons.
The use process of the intelligent anti-trailing door system (as shown in the figure below):

3. Application occasions of bank anti-trailer access control system
• Banks, treasury, finance and other important regions or departments need to be closely monitored.
• The places to be monitored are widely distributed and large in number, and occasions where unified network management is required.
• The place to be monitored is in the same area, but it is not convenient for wiring due to factors such as the environment, and each controller point is equipped with network resources (such as local area network).
4. Case analysis: (take the business halls of Beijing Bank of Communications as an example)
This system uses aDouble door interlock controllerControl two doors: public area A area-transit area B area door 1#, transit area B area-controlled area C area door 2#, all personnel entering and leaving the bank’s business hall must use a combination of swiping card and password, when When bank personnel need to enter the controlled area C: first verify their identity outside door #1 (such as swiping a card and add a password), and the system will automatically detect the status of door #2. If the personnel’s identity verification is passed, and the system detects that door #2 is In the closed state, door 1# opens and personnel enter zone B (transfer area), and the system automatically closes gate #1. At this time, the personnel are safely locked in zone B of the transfer; personnel verify their identity in front of gate #2 (such as swiping a card to add Password), and the system automatically detects the status of door 1#. If the personnel authentication is passed and the system detects that door 1# is closed, door 2# opens and the person enters the controlled area C, and the system automatically closes door 2# .
When a person arrives from the controlled area C to area A: the person verifies their identity in door 2# (such as swiping a card and adding a password), and the system detects the status of door 1#. If door 1# is closed, door 2# opens and the person Entering area B, the system automatically closes door 2#; personnel verify their identity in area B (such as swiping a card and adding a password), and the system checks the status of door 2#. If door 2# is closed, door 1# opens and personnel arrive at area A , The system automatically closes 1# door.

Flowchart of using intelligent anti-trailer door system
If a bank employee swipes a card + a 4-digit duress code on the first door when being duressed by an illegal person, the first door can be opened normally at this time, and an alarm signal will be issued when the door is opened. Or alarm bells, etc.); remind the staff on duty to take corresponding measures. These actions are carried out quietly without the knowledge of illegal personnel, which can further protect the lives of employees.
After entering the transit area, employees should deal with the criminals, delaying time and waiting for the security department to take action. Can deliberately not close the first door, at this time the second door cannot be opened in any way. When the gangsters are extremely vicious, employees can close the first door and re-enter the duress password when opening the second door to pass the duress alert to the relevant departments again. Employees in the business hall can transmit the alarm to the relevant departments through the alarm device installed in the hall, or press the emergency double-close button in the business hall after the gangster enters the transfer area, and the system enters the alarm state, and it is in the transfer area. The personnel in the area will not be able to open the door in any way until the manual switch is turned on again. Since this method may threaten the lives of employees who are still in the transfer area, the double-close button cannot be activated under compelling circumstances.
When a fire or other emergencies occur in the business hall, you can also press the “emergency double open” button in the business hall and open the double doors at the same time to complete the quick and safe evacuation of all personnel, which meets the fire safety requirements.
