Description

Technical Field

[0001] This invention relates to the field of airport terminal access control and security facilities, and in particular to an intelligent access control system for airport conveyor belt openings. Background Technology

[0002] The landside of a civil aviation airport refers to the area freely accessible to both passengers and non-passengers, while the airside refers to the area within the aircraft movement area and buildings such as terminals, cargo terminals, and access gates, separated from the aircraft movement area by security checkpoints. According to the relevant regulations in the "Security Facilities for Civil Transport Airports" (MHT 7003-2017), areas on the airside and areas with different security levels must be closed off, and security facilities (hereinafter referred to as security facilities) must be installed at the entrances from the landside to the airside and between areas with different security levels on the airside. According to this regulation, the openings connecting the airside and landside of the baggage check-in conveyor belt in the terminal building, the conveyor belt openings between the baggage sorting area and the baggage claim area, and the openings connecting the airside and landside of the cargo conveyor belt in the cargo terminal (collectively referred to as conveyor belt openings) should all be closed off and equipped with security facilities to prevent unauthorized entry or the transfer of items. Currently, airport conveyor belt openings are mainly closed off using physical isolation facilities such as lockable metal grilles or electric fireproof roller shutters, but the following problems exist:

[0003] (1) During the period when the physical isolation facilities are open or closed, the conveyor belt opening is unattended and cannot prevent people from illegally entering the airside from the landside of the conveyor belt opening or illegally entering the baggage sorting area from the baggage claim area.

[0004] (2) The operation of physical isolation facilities and the inspection of their opening or closing status can only be carried out manually one by one. For large airports with dozens or hundreds of conveyor belt openings, this will undoubtedly consume a lot of manpower and there is a risk of oversight.

[0005] (3) The conveyor belt opening lacks an intelligent access control system, which cannot remotely operate and centrally manage the physical isolation facilities of the conveyor belt opening. It cannot monitor in real time the opening or closing status of the physical isolation facilities, or whether someone illegally crosses the conveyor belt opening. When someone illegally crosses or illegally opens the physical isolation facilities, it cannot alarm and link the monitoring camera to notify the on-duty personnel to handle the situation.

[0006] (4) Although electric fireproof roller shutters installed at the conveyor belt opening can be used as closed management facilities for the conveyor belt opening, and can be electrically controlled and linked with the fire protection system to open or close, according to the comparative documents such as "Fireproof Roller Shutter Part 3: Fireproof Roller Shutter Controller" (GB14102.3-2024) and "Fireproof Roller Shutter Control System and Fireproof Roller Shutter Control Method" (invention patent, publication number CN117052269A), electric fireproof roller shutters belong to fire protection facilities and cannot be connected to the security platform for centralized management as access control system facilities. They do not have intelligent access control functions such as real-time monitoring of personnel illegally crossing the conveyor belt opening, real-time monitoring of the conveyor belt opening by connecting video surveillance cameras, and alarm linkage.

[0007] (5) If access control, alarm, video surveillance and other systems are added to the conveyor belt opening to implement intelligent access control, the existing technology requires multiple access control controllers, alarm processors, POE switches and other equipment to be added according to the number of conveyor belt openings. In addition, there are many cables to be laid from the weak current room to the conveyor belt opening, which will greatly increase the project cost and make it difficult to implement.

[0008] Therefore, it is essential to design an intelligent access control system for airport conveyor belt entrances. Summary of the Invention

[0029] The system workstation 7 is connected to an alarm speaker 7-1, has built-in system management software and mobile APP management software, and is connected to the security platform.

[0030] The main functions and control principles of an intelligent access control system for airport conveyor belt entrances include:

[0031] (1) The system workstation 7 has built-in system management software and mobile APP management software. Staff can use the system workstation 7 or the mobile APP client software to send instructions to the I / O control module 1-22 of the dedicated control box 1 to switch the power supply of the roller shutter motor 2-11 and the electromagnetic lock body (including door magnet) 3, and to open or close the electric roller shutter device 2. When the airport is operational, the system workstation 7 sends a command to the I / O control module 1-22 to activate the roller shutter motor 2-11 at a predetermined time. The I / O control module 1-22 then connects the power supply to the roller shutter motor 2-11 via relay 1-3 for standby. After the airport is closed and the electric roller shutter device 2 is locked, the system workstation 7 sends a command to the I / O control module 1-22 to deactivate the roller shutter motor 2-11. The I / O control module 1-22 then disconnects the power supply to the roller shutter motor 2-11 via relay 1-3 to prevent unauthorized opening of the electric roller shutter device 2. When it is necessary to activate the electric roller shutter device 2, the system workstation 7 sends a command to the I / O control module 1-22 to activate the roller shutter motor 2-11. -22 issues a command, and the I / O control module 1-22 automatically cuts off the power supply to the electromagnetic lock body (including the door magnet) 3 to unlock it, and drives the roller shutter motor 2-11 to roll the metal roller shutter 2-2 into the roller shutter head 2-1; when it is necessary to lock the electric roller shutter device 2, the system workstation 7 issues a command to the I / O control module 1-22, and the I / O control module 1-22 automatically turns on the power supply to the electromagnetic lock body (including the door magnet) 3, and drives the roller shutter motor 2-11 to lower the metal roller shutter 2-2 to the top of the luggage or cargo conveyor belt 10. After the electromagnetic lock body (including the door magnet) 3 attracts the iron bottom frame (electromagnetic lock suction plate) 2-3 of the metal roller shutter, it locks the electric roller shutter device 2.

[0032] (2) The dedicated control box 1 is equipped with the electromagnetic lock switch 1-4 and the roller shutter controller 1-5. The staff can use the electromagnetic lock switch 1-4 and the roller shutter controller 1-5 to manually open or close the electric roller shutter device 2.

[0033] (3) The I / O control module 1-22 can obtain the open or closed status signal of the electric roller shutter device 2 through the door magnet in the electromagnetic lock body (including door magnet) 3 and transmit it to the system workstation 7. When the electric roller shutter device 2 is not opened or closed within the specified time, or is forcibly opened, the system workstation 7 activates the alarm speaker 7-1 to emit an alarm sound and links the POE monitoring camera 5 to inspect the scene.

[0034] (4) The RS485 / TCP communication conversion module 1-23 can acquire the alarm signal of the infrared human body detector 4 and convert it into a TCP network signal; when the infrared human body detector 4 detects that someone illegally crosses the conveyor belt opening 9, the infrared human body detector 4 will issue an audible and visual alarm on site and transmit the alarm signal to the system workstation 7 through the RS485 / TCP communication conversion module 1-23. The system workstation 7 will activate the alarm speaker 7-1 to emit an alarm sound and link the POE monitoring camera 5 to inspect the site.

[0035] (5) The system workstation 7 can remotely configure the I / O control module 1-22, RS485 / TCP communication conversion module 1-23, POE switch module 1-24, and POE monitoring camera 5, and can monitor the working status of the dedicated control box 1, roller shutter motor 2-11, electromagnetic lock body (including door magnet) 3, infrared human body detector, and POE monitoring camera 5, thereby achieving the purpose of centralized control and management of security facility system.

[0036] This invention provides an intelligent access control system for airport conveyor belt openings. By integrating power modules, I / O control modules, RS485 / TCP communication conversion modules, and PoE switch modules, and providing system management software and mobile APP software, it realizes the functions of access controllers, alarm processors, PoE switches, and electric roller shutter controllers for conveyor belt opening access control. This simplifies the system structure, reduces equipment and cable material costs and engineering costs, and facilitates implementation. The electric roller shutter can be operated via a system workstation, mobile APP, or manually. It allows real-time monitoring of the status of conveyor belt opening access control facilities and situations such as unauthorized crossings. In case of abnormalities, an alarm is triggered to activate monitoring cameras. The system allows for centralized management of conveyor belt opening access control facilities and networking with a security platform, thereby achieving intelligent access control for airport conveyor belt openings and facilitating use. This intelligent access control system for airport conveyor belt openings solves the technical challenges of intelligent access control for airport conveyor belt openings and complies with relevant industry standards and specifications for civil aviation airport security facilities.

The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. Furthermore, those skilled in the art will recognize that, based on the ideas of the present invention, there will be changes in the specific implementation methods and application scope.
