Abstract

The invention discloses an access control system for the cockpit door of an aircraft and the aircraft. The access control system includes an independently operated main latch device and a backup latch device, a controller, a verification device located on one side of the passenger compartment, and a verification device located on the cockpit. Pilot's control panel on one side. Wherein, the backup latch device is an electromagnetic lock assembly, and the controller communicates with the verification device and the pilot control panel, and the verification device is preset with first and second verification information. The controller can send an unlock request to the pilot control panel in response to the first verification information input through the input interface, and control the electromagnetic lock assembly and / or main latch mechanism unlocked. According to the access control system for the cockpit door of the aircraft and the aircraft of the present invention, the risk of hijacking by a single pilot can be completely eliminated while realizing the function of preventing cabin occupants from illegally entering the cockpit.

Description

technical field [0001] The invention relates to the technical field of aircraft security, in particular to the design of an aircraft cockpit door security system or an access control system, and in particular, relates to an access control system for an aircraft cockpit door and an aircraft. Background technique [0002] The reason for the disappearance of Malaysia Airlines MH370 in 2014 has not yet been determined, and the hijacking of the pilot is one of the guesses. The cause of the crash of the Germanwings A320 in 2015 was determined to be that the co-pilot locked the cockpit door after the captain went to the bathroom and took control of the plane alone, causing the crash. Since then, how to eliminate the potential risk of hijacking or crashing when a single pilot is in the cockpit has attracted much attention in the field of civil aviation. [0003] The current access control system design for the cockpit door is generally based on the following two requirements: [0...
