Description

Technical Field

[0001] The present invention relates to the technical field of security facilities for access control in airport terminals, and particularly to an intelligent access control system for conveyor belt openings in airports. Background Art

[0002] The landside of a civil aviation airport refers to the area where passengers or non - passengers can freely enter and exit, while the airside refers to the area where aircraft operate and the areas within buildings such as terminals, freight stations, and checkpoints that are connected to the aircraft operating area through security check channels. According to the relevant regulations of "Security Facilities for Civil Transport Airports" (MHT 7003 - 2017), areas with different security levels on the airside and landside must be closed for management, and security facilities (hereinafter referred to as security facilities) must be installed at the access points between the landside and the airside and between areas with different security levels on the airside. According to this regulation, openings where the luggage conveyor belts on the landside and airside of the terminal are connected, openings of conveyor belts between the luggage sorting area and the luggage claim area, and openings where the cargo conveyor belts on the landside and airside of the freight station are connected (collectively referred to as conveyor belt openings) should all be closed for management and security facilities should be installed to prevent unauthorized entry or item transfer. Currently, the conveyor belt openings in airports are mainly closed for management using physical isolation facilities such as lockable metal grilles or electric fire - resistant rolling shutters, but there are the following problems:

[0003] (1) During the opening or locking of the physical isolation facilities, the conveyor belt openings are unattended, and it is impossible to prevent someone from illegally entering the airside from the landside of the conveyor belt opening or from illegally entering the luggage sorting area from the luggage claim area.

[0004] (2) The operation of the physical isolation facilities and the inspection of their opening or locking 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 large amount of manpower and there is a risk of oversight.

[0005] (3) The conveyor belt openings lack an intelligent access control system, and it is impossible to remotely operate and centrally manage the physical isolation facilities of the conveyor belt openings, and it is impossible to monitor in real - time the opening or locking status of the physical isolation facilities, whether someone has illegally crossed the conveyor belt opening, etc. When someone illegally crosses or illegally opens the physical isolation facilities, it is impossible to alarm and link with the monitoring cameras and notify the duty personnel to go and handle it.

[0006] (4) Installing an electric fire shutter at the conveyor belt opening can be used as a closed management facility for the conveyor belt opening. It can be electrically controlled and can be linked with the fire protection system to open or lock. However, according to the "Fire Shutter - Part 3: Fire Shutter Controller" (GB14102.3 - 2024) and the "Fire Shutter Control System and Fire Shutter Control Method" (patent for invention, publication number CN117052269A) and other comparative documents, the electric fire shutter belongs to a fire protection facility and cannot be connected to the security platform for centralized management as a traffic control system facility. It does not have intelligent traffic control functions such as real - time monitoring of personnel illegally crossing the conveyor belt opening, accessing video surveillance cameras to monitor the conveyor belt opening in real - time, and alarm linkage.

[0007] (5) If additional systems such as access control, alarm, and video surveillance are added at the conveyor belt opening for intelligent traffic control of the conveyor belt opening, according to the existing technology, multiple sets of access control controllers, alarm processors, POE switches, etc. need to be added according to the number of conveyor belt openings, and there are also more cables laid from the weak - current room to the conveyor belt opening, which will greatly increase the project cost and is not conducive to implementation.

[0008] Therefore, it is very necessary to design an intelligent traffic control system for airport conveyor belt openings. Summary of the Invention

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

[0034] (4) The RS485 / TCP communication conversion module 1-23 can obtain the alarm signal of the infrared human detector 4 and convert it into a TCP network signal; when the infrared human detector 4 detects that someone illegally crosses the conveyor belt hole 9, the infrared human detector 4 sends out an audible and visual alarm on the spot, and transmits the alarm signal to the system workstation 7 through the RS485 / TCP communication conversion module 1-23. The system workstation 7 starts the alarm speaker 7-1 to send out an alarm sound, and links the POE monitoring camera 5 to inspect the scene.

[0036] The invention provides an intelligent access control system for the opening of a conveyor belt at an airport. By integrating circuits such as a power module, an I / O control module, an RS485 / TCP communication conversion module, and a POE switch module, and providing system management software and mobile phone APP software, the system structure is simplified, the material cost of equipment cables and the engineering cost are reduced, and the implementation is facilitated.
