[0010] According to one aspect of the present invention, the control command of the cabin control panel has a higher priority than the control command of the door control switch.

[0011] According to one aspect of the present invention, the cabin door control switch includes a cabin door control switch located inside the first-class cabin seat box and an outside cabin door control switch. The inside cabin door control switch is set on the inside panel of the first-class cabin seat box, allowing operation inside the first-class cabin seat box. This structure conforms to the operating habits and cognition, is convenient for passengers to operate, and can prevent passengers from being accidentally pinched by the cabin door when operating the switch; in addition, the layout position of this control switch is close to the mechanical structure of the control cabin door, which is convenient for maintenance. The outside cabin door control switch is set on the outer door frame of the first-class cabin seat box, allowing operation outside the seat box. This structure has a clear layout position and appearance, and the installation height is convenient for flight attendants or passengers to operate while standing.

[0012] According to one aspect of the present invention, the cabin door control switch is of button type, having a cabin door closing button and a cabin door opening button, which are respectively used to control the closing and opening of the cabin door, wherein the cabin door closing button is arrow-shaped, pointing in the direction of the nose of the aircraft, wherein the cabin door opening button is arrow-shaped, pointing in the direction of the tail of the aircraft.

[0013] According to one aspect of the present invention, the sensor includes a cabin door closing sensor, which has a proximity sensing block and a proximity switch sensor, wherein the proximity sensing block is installed in the cabin door of the first-class seat and moves with the cabin door, wherein the proximity switch sensor is installed on the slide rail of the cabin door of the first-class seat, close to the extreme position of the cabin door when opening or closing, wherein during opening or closing of the cabin door, when the position movement of the cabin door overlaps with the proximity switch sensor, the proximity switch sensor sends a signal of the position of the cabin door to the cabin door control module, and then the cabin door control module sends a cabin door command to the cabin door actuator, instructing the cabin door actuator to stop actuating.

[0014] According to one aspect of the present invention, the sensor includes a cabin door infrared sensor, which has a transmitting end and a receiving end, wherein the transmitting end transmits an infrared beam, wherein the receiving end receives the infrared beam, wherein when an object blocks the infrared beam, the receiving end cannot receive the infrared beam, and the cabin door infrared sensor sends a signal indicating that the infrared beam is blocked to a cabin door control module, and then the cabin door control module sends a cabin door command to a cabin door actuator, instructing the cabin door actuator to stop actuating.

[0015] According to one aspect of the present invention, the cabin control panel includes a cabin control page, which receives door status information sent by a door control module, and displays the door status information of the door on the cabin control page, wherein the door status information includes: open, closed, locked, over-control, faulty, etc.

[0016] According to one aspect of the present invention, a door status indicator light is also included, which receives door status information sent from the door control module and indicates the door status through the color of the light.

[0017] According to one aspect of the present invention, a door status indicator light is disposed on the outer wall panel of the first-class cabin seat box, and the door status indicator light has five colors, corresponding to five states of the door: open, closed, locked, over-control, and fault.

[0018] Lock: When the cabin door is locked by the flight attendant through the door control page, passengers cannot open and close the cabin door through the door control switches inside and outside the first-class seats.

[0019] Override: The door control module is designed with automatic door control logic, which can override the control instructions on the door control page and the door control switch. When the flight attendant locks the door through the door control page, passengers cannot operate the door opening and closing through the door control switches inside and outside the first-class seats.

[0020] Fault: When a door fails, the door status indicator light indicates the fault status.

[0021] When the cabin door is open, the indicator light turns green; when the cabin door is closed, the indicator light turns red; when the cabin door is locked by the flight attendant, the indicator light turns purple; when the cabin door is overridden by the cabin door control module, the indicator light turns blue; when the cabin door fails, the indicator light turns yellow.

[0022] According to one aspect of the present invention, the priority of the door control module in overriding the door is higher than the control instructions of the cabin control panel and the control instructions of the door control switch.

The door control module communicates with the door control device, door status indicator light, door sensor, and door actuator through a data bus, and communicates with the cabin control panel through an avionics network.

[0024] The door control module collects the door control signals from the cabin control panel and the door control switch, drives the door actuator to open and close the door. The door control module collects the signals of the sensors installed on the door (door closing sensor, door infrared sensor) and sends them to the door control module. After judging and processing the sensor signals, the door control module sends the door status to the cabin control system through the avionics network for the door status indication on the door control page, and sends the door status to the door status indicator through the data bus to indicate the door status.

[0025] The door control module is connected to the aircraft's avionics network to enable flight attendants to control the first-class seat doors, monitor their status and perform other operational needs.

[0026] This patent application takes into account the operation scenarios of civil aircraft, for example: the control and monitoring of the cabin door of the first-class cabin by the cabin control component (for example: when the aircraft takes off and lands, the flight attendant can confirm that the cabin door is in the open state through the cabin door control page 12).

[0027] The invention systematically designs a door control architecture and logic for first-class cabin seat doors, takes into account actual operating conditions such as door opening, closing, and override control, adds override technology compared to the mechanical control of other cabin doors, and installs sensors on the cabin doors to achieve precise control of door position, accidental collision, etc., and increases the control of the first-class cabin seat doors by the cabin control components.

[0028] The invention is based on the use requirements of the first-class cabin door and the aircraft operation scenarios, and designs the functions and logic of the cabin door control component. When designing the architecture of the first-class cabin door control component, reference was made to the design of the cockpit of a civil aircraft, and logical cabin door control (control device) and feedback (cabin door status indication) were provided for the relevant personnel using the cabin door to ensure that the connection between the cabin door control and its indication is easy to understand, which facilitates the management and monitoring of the cabin door. In addition, different cabin door operating modes and corresponding operating logics are designed in combination with the cabin door use requirements under different aircraft operation scenarios, which improves the automation level of cabin door control.
