when the fact that the display operation unit receives the pre-positioning releasing signal is detected, the pre-positioning actuator is electrified, and a seventh control instruction is sent to the pre-positioning actuator, wherein the seventh control instruction is used for indicating the pre-positioning actuator to perform reverse operation so that the pre-positioning mechanism moves towards the first preset position;

when the fact that the pre-positioning actuator receives a positioning signal sent by the pre-positioning sensor is detected, the pre-positioning actuator is powered off, an eighth control instruction is sent to the pre-positioning actuator, the positioning signal is used for indicating the pre-positioning mechanism to reach a first preset position, and the eighth control instruction is used for indicating the pre-positioning actuator to stop executing reverse rotation operation. The disarming operation is completed.

In order to realize the automatic pre-positioning function after the cabin door is closed, the method further comprises the following steps:

In order to prevent the cabin door lock shaft from moving, and further prevent the cabin door from being accidentally opened in the air, the safety of the accidental opening of the cabin door is improved. The method further comprises the following steps:

In order to ensure the safety of the flight in the emergency state, the method further comprises the following steps:

when detecting that the display operation unit receives the emergency signal, detecting whether the display operation unit receives a door opening signal;

when detecting that the display operation unit receives a door opening signal, executing the opening operation of the cabin door;

sending an eleventh control instruction to the opening actuator, wherein the eleventh control instruction is used for indicating the opening actuator to start the emergency actuating device so as to open and lock the cabin door to the maximum position;

when a first complete opening signal sent by a gust lock sensor is received, the power supply for the opening actuator is stopped, a second complete opening signal is sent to the display operation unit, the first complete opening signal is used for indicating the cabin door to be opened and locked to the maximum position, and the second complete opening signal is used for indicating the display operation unit to control the complete opening signal lamp to be on.

The method for operating the cabin door combines the control panel instruction to electrify different actuators, drives the actuators to move, and enables the cabin door to finish unlocking of the flight lock, unlocking of the pre-positioning, unlocking, lifting, opening, locking and opening of the gust lock and reverse door closing actions.

The method for operating the cabin door can realize automatic operation of the boarding door, and in the face of the increasingly heavy boarding door of a large-sized wide-body passenger plane, the device can effectively reduce physical strength paid by operators for unlocking and lifting the boarding door, reduces risk of bringing people out of the airplane when the cabin door is opened, is simple and clear in operation interface, clear in cabin door state indication, and capable of effectively realizing mechanism blanking, merging cabin door monitoring and actuation signal detection units, and better realizes state monitoring and centralized management of the cabin door of the airplane.

The foregoing is merely a detailed description of the embodiments of the present invention, and some of the conventional techniques are not detailed. The scope of the present invention is not limited thereto, and any changes or substitutions that can be easily made by those skilled in the art within the technical scope of the present invention will be covered by the scope of the present invention. The protection scope of the present invention shall be subject to the protection scope of the claims.
