the access control panel is used for outputting pilot off-site signals or on-site signals controlled by pilots when the pilots leave seats; or outputting a cockpit door locking signal or a cockpit door unlocking signal controlled by a pilot;
the cipher device is used for outputting a correct signal of the secret information or an error signal of the secret information after receiving the secret information input by the pilot and comparing the secret information with the pre-stored door opening information;
the logic controller is connected with the access control panel, the cipher device and the cockpit door and is used for distributing the highest access right for controlling the cockpit door to be opened and closed according to whether the cockpit door locking signal and the pilot in-place signal are received when the pilot is in the seat and receives the abnormal door opening signal; or (b)
The method is used for allocating the highest access rights in the seats of single-flight operators according to the received correct signals of the secret information or the received error signals of the secret information input by the pilot leaving the seats.
The access control system of the cockpit door according to the present embodiment will be described in detail with reference to the drawings. Referring to fig. 1, a schematic structural diagram of an access control system for a cockpit door in an embodiment is shown. The cockpit door access control system 1 according to the present embodiment is used for controlling a cockpit door 2 of an aircraft, as shown in fig. 1, where the cockpit door access control system 1 includes an access control panel 11, a password device 12, and a logic controller 13.
In this embodiment, please refer to fig. 2, which shows a schematic plan view of an access control panel in an embodiment. As shown in fig. 2, the access control panels 11 are respectively disposed on two sides of the pilot, one side of the access control panel 11 is provided with an access control knob 111, and the other side is provided with a cockpit door unlocking indicator light 112 and a cockpit door automatic opening indicator light 113. The door control knob 111 is provided with:
an AUTO-lock gear, AUTO gear 111A, for outputting pilot on-position signals by pilot control; under normal conditions, when the knob is in the AUTO gear, the driving cabin door is locked after being closed.
A pilot out of gear, LEAVE gear 111B, for control by the pilot to output a pilot out of gear signal;
a lock gear for outputting a cockpit door lock signal, i.e., a DENY gear 111C, by pilot control. In this embodiment, the lock gear also indicates when the pilot has turned the knob to the DENY gear after the pilot has received an abnormal cabin entry request while sitting, at which point the cockpit door is locked.
And a door opening gear for outputting a door opening signal, i.e., a UNLK gear 111D, by pilot control.
In this embodiment, the access control panel 11 is specifically configured to output a pilot out-of-position signal or an in-position signal by controlling the LEAVE gear 111B by the pilot when the pilot LEAVEs his seat. In this embodiment, the pilot on-position signal is represented by a "0" and the pilot off-position signal is represented by a "1".
In this embodiment, the access control panel 11 is further configured to output a cockpit door lock signal or a cockpit door lock signal by controlling the DENY gear 111C by a pilot. The cockpit door lock signal is indicated by a "1" and the cockpit door unlock signal is indicated by a "0". The access control panels are respectively arranged at two positions on two sides of the pilot, and the like, so that one pilot cannot operate at the same time.
The cipher 12 connected to the entrance guard control panel 11 and set on the cockpit door is used to receive the secret information from pilot and compare with the pre-stored door opening information to output the correct signal or error signal of the secret information. In other words, after receiving the secret information input by the pilot, the secret information input by the pilot is compared with the pre-stored door opening information, and if the secret information input by the pilot is consistent with the pre-stored door opening information, the cipher outputs a correct signal of the secret information, which is indicated by '1'. If the secret information input by the pilot is inconsistent with the pre-stored door opening information, the cipher outputs an error signal of the secret information, which is indicated by 0. In this embodiment, the confidential information is input only once, and thus, the pilot outside the cockpit can easily destroy the confidential information. The pilot in the cockpit can still reject the abnormal access request at this time to keep the cockpit safe. In this embodiment, the code device 12 is disposed at a fixed approximate location of the cockpit door, door sidewall, or roof.
The logic controller 13 is connected with the access control panel 11, the cipherer 12 and the cockpit door 2 and is used for distributing the highest access right for controlling the opening and closing of the cockpit door according to whether the cockpit door locking signal and the pilot in-place signal are received when the pilot is in the seat and receives the abnormal door opening signal; or the logic controller 13 is used for allocating the highest access rights in the seats of the single flight crews according to the received correct signals of the secret information or the error signals of the secret information input by the pilot leaving the seats.
Referring to FIG. 3, a logic circuit diagram of a logic controller in one embodiment is shown. As shown in fig. 3, the logic controller 13 includes a first nand gate 131, a first and gate 132, a second and gate 133, a second nand gate 134, a first nor gate 135, a first nor gate 136, a third and gate 137, a second nor gate 138, and a second nor gate 139. The first nand gate 131 is connected with the first and gate 132, and the first and gate 132 is connected with the second and gate 133; a second nand gate 134 is connected to the second and gate 133 and is connected in parallel to the first and gate 132; the first nor gate 135 is connected to a first not gate 136, and the first not gate 136 is connected to a third and gate 137; the second and gate 133 and the third and gate 137 are connected in parallel to the second nor gate 138, and the second nor gate 138 is connected to the second nor gate 139. In this embodiment, the first nand gate 134 is configured to receive a response signal that can be fed back by the pilot to the abnormal door opening signal at the same time within a predetermined period of time. The predetermined period of time is set to 30s in the present embodiment. Therefore, the response signal is called as a 30s response signal in the embodiment, namely, the double pilots feed back an abnormal door opening signal within 30s, and simultaneously output a cab door locking signal, wherein the 30s response signal is 1; the 30s double pilots do not feed back abnormal door opening signals at the same time, namely, the driving cabin door unlocking signals are output at the same time, and the 30s response signals are 0; the 30s double pilots do not feed back the abnormal door opening signals at the same time, namely, the abnormal door opening signals comprise that one pilot outputs a cockpit door locking signal, the other pilot outputs a cockpit door unlocking signal, the double pilots output the cockpit door unlocking signal after 30s, and the 30s response signal is 0".
In this embodiment, because it is impossible for the knob of the access control panel 11 to make LEAVE and DENY act simultaneously, the logic controller further includes a first or gate 140 and a second or gate 141 connected to the first nand gate 131.
In this embodiment, 4 preset scenes are set to achieve the allocation of the highest rights.
A first preset scenario:
preset scene 1: double pilots are in the seat, have no disability and suffer from hijacking
During normal flight, the unit places both side knobs in the AUTO position. The left and right pilots receive the abnormal door opening signal, and simultaneously adjust the door control knob to the DENY gear and receive the emergency door opening signal. At this time, the cockpit door is locked, and the cockpit unit, namely two pilots commonly have the highest authority. See table 1: the truth table for scenario 1 is preset.
When the double pilots are in the seats and receive the abnormal door opening signals, the highest access control authority is distributed to the cockpit unit through a logic circuit diagram shown in fig. 3 according to the received cockpit door locking signals, pilot in-place signals and emergency door opening signals input by the cabin unit.
Table 1: truth table of preset scene 1
A second preset scenario: double flying seats, disabled single flight personnel and no robbery
Third preset scenario: double flying seats, disabled double pilots and no robbery
If the unit is disabled, two persons cannot necessarily adjust the control knobs on two sides to the DENY gear at the same time. The cabin unit can use an emergency access code (an abnormal door opening signal is received) outside the cockpit, two DENY signals cannot be obtained simultaneously within a period of time, and then the cabin door is automatically opened, and the cabin unit can enter the cockpit to control an airplane.
Specifically, when the pilot seats and receives the abnormal door opening signal, the highest access control authority is allocated to the cabin unit through a logic circuit diagram shown in fig. 3 according to the response signal, the pilot in-place signal and the cockpit door unlocking signal which are fed back by the pilot during a preset time period and are simultaneously fed back by the pilot. See table 2 for truth tables for preset scenarios 2 and 3.
Table 2: truth table for preset scenes 2 and 3
Fourth preset scenario: single flight seats (one pilot leaves the cockpit and the other pilot is in the cockpit), no disability and no hijacking
During cruise, either pilot may leave the cockpit. Before leaving, one side of the access control knob is adjusted to the LEAVE gear, namely one side outputs an on-position signal, and the other side outputs an off-position signal (the other side of the access control knob is still in the AUTO gear). The door password (or fingerprint sensor) in the pilot is activated. The pilot can open the door by clicking a personal code on the door password device (or using a certain finger to collect fingerprints on the fingerprint collector). After the pilot leaves, the cabin door is closed and automatically locked. The highest access rights at this point is the pilot's personal code (or some finger print). The next highest authority is either side of the control knob. The lowest authority is the cabin crew emergency entry password. There are two ways to access the cockpit from the passenger cabin: a) Using the correct personal password or fingerprint; b) The cabin crew emergency access code is used and the pilot in the cockpit does not reject the access request.
Specifically, in a single flight attendant sitting, access control maximum authority is assigned to the out-of-seat pilot by a logic circuit diagram as shown in fig. 3 based on the on-position signal of the on-position pilot, the out-of-position signal of the out-of-seat pilot, and the correct signal of the secret information input by the pilot. See table 4 for a truth table for preset scenario 4.
Table 3: truth table of preset scene 4
Fifth preset scenario: single-flight pedestrian sitting, no disability and hijacking
The cabin door cipher device (or fingerprint collector) in the cockpit is provided with a self-locking function: if the personal code (or finger print) is input once with error (namely the error signal of secret information), the power is automatically cut off, and the control right of the cabin door is lost. A pilot encountering hijacking outside the cockpit may lock the dead door code by entering a wrong personal code (or a wrong finger print). At the moment, the access control knob of the highest access right of the cockpit is at any side. Even if a terrorist acquires a cabin emergency entry code, a single pilot can still adjust the control knob to the DENY position to DENY access.
Specifically, in a single flight crew sitting, the gate cap is assigned to the pilot still sitting in the cockpit crew by the logic circuit diagram shown in fig. 3 according to the presence signal of the pilot in place, the absence signal of the pilot out of place, and the error signal of the secret information input by the pilot. See table 4 for a truth table for preset scenario 5.
Table 4: truth table of preset scene 5
The access control system of the cockpit door of the embodiment has the highest access control right through the distribution of the highest access right, when a hijack is encountered, a flight unit in the cockpit has the highest access control right, and the possibility that terrorists attack the cockpit is eliminated. When a single flight pedestrian is sitting, the pilot leaving the seat has the highest access control right and can timely return to the cockpit, so that the occurrence probability of an intentional crash event is effectively reduced. When a single flight driver sits and encounters hijacking, the flight units in the cockpit regain the highest access control right, and terrorists are prevented from entering the cockpit when the flight units are in the gap. When the flight unit of the cockpit is disabled, the cabin unit has the highest right of entering the cockpit. Therefore, the access control system of the cockpit door can effectively cope with various preset scenes, prevent hijacking and intentional crash events and ensure flight safety.

And when the pilot seats and receives the abnormal door opening signal, the highest access control authority is distributed to the cabin unit according to the response signal, the pilot in-place signal and the cockpit door unlocking signal which are fed back by the pilot to the abnormal door opening signal in a preset time period.
Or the control method comprises the following steps:
s1', in the presence of a single flight attendant, the highest access control right is allocated according to the received correct signal of the secret information or the received error signal of the secret information input by the pilot leaving the seat.
Specifically, in a single flight attendant sitting, the highest access rights are assigned to the out-of-seat pilot based on the on-position signal of the on-position pilot, the out-of-position signal of the out-of-seat pilot, and the correct signal of the confidential information entered by the pilot.
In a single flight crew sitting, access control maximum authority is assigned to the pilot still sitting by a logic circuit diagram as shown in fig. 3 according to the on-position signal of the on-position pilot, the off-position signal of the off-position pilot, and the error signal of the secret information input by the pilot.
