Description

Technical Field

[0001] The invention belongs to the field of aerospace technology and relates to a management system and method for collaborative work rights management of front and rear cabins of an aircraft. Background Art

[0002] On all types of aircraft, the authority to plan routes, preset headings, and operate the autopilot functions to make the aircraft fly according to the planned route or preset heading usually only belongs to the pilots in the cockpit (front cabin), and the relevant staff in the passenger cabin (rear cabin) do not have the relevant authority.

[0003] On some special aircraft models, in order to perform tasks such as aerial photography and aerial measurement, the relevant staff in the cabin (rear cabin) have higher command authority than the pilots in the cockpit (front cabin) when performing tasks.

[0004] On a certain type of aircraft, cabin (rear cabin) staff can only observe the position information of the aircraft relative to the coastline, route, airport and aviation beacon through the electronic map display. The information displayed on the electronic map display all comes from the onboard global positioning system. The control components of the onboard global positioning system are all on the dashboard of the cockpit (front cabin). On this type of aircraft, the autopilot system is coupled with the global positioning system to control the aircraft to fly according to the route planned by the onboard global positioning system. All the control components of the autopilot system are on the control panel of the cockpit (front cabin). That is, the authority to plan the route and control the autopilot of this type of aircraft is in the front cabin, and the cabin (rear cabin) staff only have the right to observe, not the right to control. When a problem with the route planning is found, or the actual position of the aircraft deviates from the planned route and does not meet the mission requirements, the cabin (rear cabin) staff need to notify the cockpit (front cabin) pilot to modify the route planning or control the aircraft to deviate through the machine communication system and other means. It is impossible to directly modify the route planning or control the aircraft to deviate, resulting in low efficiency and poor results in mission execution. Summary of the invention

[0005] Technical problems solved by the present invention:

[0006] In a certain type of aircraft, cabin (rear cabin) related staff with higher command authority do not have control authority over the aircraft. When performing tasks, they cannot directly solve problems after discovering them, and need to command the pilot to perform them indirectly, resulting in low efficiency and poor results in task execution. In order to overcome the deficiencies of the prior art, the purpose of the present invention is to give cabin (rear cabin) related staff appropriate control authority while ensuring the flight safety of the aircraft, and to reasonably realize the authority allocation between the cockpit (front cabin) pilot and cabin (rear cabin) related staff.

[0007] Technical solution of the present invention

[0008] A collaborative authority management system for front and rear cabins of an aircraft includes an authority switch, a front cabin control display, and an autopilot system arranged in the front cabin of the aircraft, and a rear cabin control display arranged in the rear cabin. The authority switch is connected to the front cabin control display and the rear cabin control display respectively, and the front cabin control display and the rear cabin control display are both connected to the autopilot system.

[0009] Furthermore, the front cabin and the rear cabin are both provided with integrated displays, and the integrated displays of the front cabin and the rear cabin are both connected to the autopilot system for displaying the working status of the autopilot system.

[0010] Furthermore, a waypoint editing module and a route planning module are provided in the front cabin control display and the rear cabin control display. The waypoint editing module is used to edit waypoints in the front cabin control display and the rear cabin control display; the route planning module is used to plan routes in the front cabin control display and the rear cabin control display.

[0011] Furthermore, the waypoints edited by the waypoint editing module and the route planning module in the front cabin control display and the waypoints and the planned routes are stored in the front cabin data storage module; the waypoints edited by the waypoint editing module and the route planning module in the rear cabin control display and the planned routes are stored in the rear cabin data storage module, and the front cabin data storage module and the rear cabin data storage module are independent of each other.

[0012] Furthermore, the front cabin control display includes a display module, and the waypoints and route information in the front cabin data storage module are called and displayed through the display module; the rear cabin control display includes a display module, and the waypoints and route information in the front cabin data storage module are called and displayed through the display module.

[0013] A method for managing the collaborative work rights of front and rear cabins of an aircraft is provided. When the control right is in the front cabin, the display module in the front cabin control display calls the waypoint and route information of the data storage module in the front and rear cabin control displays, and has the authority to call the route and change the route. After the call is successful, the display modules of the front and rear cabin control displays synchronously display the results of calling and changing the current route. At this time, the rear cabin does not have the control right, and the rear cabin control display does not have the authority to call the route and change the route. If the rear cabin control display calls the route and changes the route, the display module in the rear cabin control display displays "no authority, call failed / change failed";

[0014] When the authority switch switches the control to the rear cabin, the cabin / rear cabin related staff can observe the route tracking situation and call the route, so that the autopilot system controls the aircraft to fly according to the route called by the display module in the rear cabin control display. Specifically, when the control is in the rear cabin, the display module in the rear cabin control display calls the waypoints and route information of the data storage modules in the front and rear cabin control displays, and has the authority to call the route and change the route. After the call is successful, the display modules of the front and rear cabin control displays synchronously display the results of calling and changing the current route; at this time, the front cabin does not have the control authority, and the front cabin control display does not have the authority to call the route and change the route. If the front cabin control display calls the route and changes the route, the display module in the front cabin control display displays "No authority, call failed / change failed";

[0015] The aircraft's real-time position information is obtained through the inertial navigation computer, which receives the route information from the data storage modules of the front and rear cabin control displays, and compares the aircraft's real-time position information with the route information to obtain the deviation between the aircraft's real-time position and the route. The inertial navigation computer transmits the deviation result to the autopilot system, and the autopilot system automatically controls the aircraft to fly according to the planned route.

[0016] Furthermore, the autopilot system automatically controls the aircraft to fly along the planned route, and relevant cabin / rear cabin staff observe the deviation between the aircraft's real-time position and the route through the display module in the rear cabin control display. When the deviation value is greater than the set threshold, the autopilot system automatically controls the aircraft to fly, continuously reducing the deviation from the route until the deviation value is less than the set threshold. The autopilot system automatically controls the aircraft to fly along the planned route, thereby realizing the aircraft's automatic navigation function.

[0017] Furthermore, when the deviation value is less than the set threshold, the relevant cabin / rear cabin staff will use the heading keeping function in the autopilot system to control the aircraft to further reduce the deviation between the aircraft's real-time position and the planned route until the mission requirements are met, thereby realizing the route deviation correction function.

[0018] Beneficial Effects

[0019] The advantage of the present invention is that it is suitable for the collaborative work of cockpit (front cabin) pilots and cabin (rear cabin) related staff, and the working scene is very special. The present invention reasonably realizes the synchronization and handover management between the front and rear cabin equipment or systems, does not interfere with the normal operation of the front and rear cabins, and realizes information sharing, better supports the decision-making of the crew, enhances the mutual support ability of the cockpit (front cabin) pilots and cabin (rear cabin) related staff, speeds up the response speed to abnormal situations and improves the handling ability.

[0020] This function enables cabin (rear cabin) staff to plan routes and control autopilots in the same way as cockpit (front cabin) pilots if they have the authority, and can flexibly switch various autopilot functions according to actual conditions, thereby enabling cabin (rear cabin) staff to correct route deviations and further eliminate steady-state deviations between the aircraft's actual position and the planned route.

[0021] This function is advanced and original among similar technologies at home and abroad. BRIEF DESCRIPTION OF THE DRAWINGS

In the detailed description below, many specific details are proposed to provide a comprehensive understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by illustrating examples of the present invention. The present invention is by no means limited to any specific settings and methods proposed below, but covers any improvements, replacements and modifications of structures, methods, devices without departing from the spirit of the present invention. In the accompanying drawings and the following description, known structures and technologies are not shown to avoid unnecessary ambiguity in the present invention.

[0028] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other, and the embodiments can refer to and quote each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] like Figure 1As shown, the present invention proposes an aircraft front and rear cabin collaborative work authority management system, including an authority switch, a front cabin control display, and an autopilot system arranged in the front cabin of the aircraft, and a rear cabin control display arranged in the rear cabin, the authority switch is connected to the front cabin control display and the rear cabin control display respectively, and the front cabin control display and the rear cabin control display are both connected to the autopilot system; integrated displays are arranged in the front cabin and the rear cabin, and the integrated displays in the front cabin and the rear cabin are both connected to the autopilot system for displaying the working status of the autopilot system.

[0030] Among them, a waypoint editing module and a route planning module are set in the front cabin control display and the rear cabin control display. The waypoint editing module is used to edit waypoints in the front cabin control display and the rear cabin control display; the route planning module is used to plan routes in the front cabin control display and the rear cabin control display; the waypoints edited by the waypoint editing module and the route planning module in the front cabin control display and the planned routes are stored in the front cabin data storage module; the waypoints edited by the waypoint editing module and the route planning module in the rear cabin control display and the planned routes are stored in the rear cabin data storage module, and the front cabin data storage module and the rear cabin data storage module are independent of each other; the front cabin control display includes a display module, and the waypoints and route information in the front cabin data storage module are called and displayed through the display module; the rear cabin control display includes a display module, and the waypoints and route information in the front cabin data storage module are called and displayed through the display module.

[0031] like Figure 2 As shown, the present invention proposes a method for managing the collaborative work authority of the front and rear cabins of an aircraft. When the control right is in the front cabin, the display module in the front cabin control display calls the waypoints and route information of the data storage modules in the front and rear cabin control displays, and has the authority to call the route and change the route. After the call is successful, the display modules of the front and rear cabin control displays synchronously display the results of calling and changing the current route. At this time, the rear cabin does not have the control right, and the rear cabin control display does not have the authority to call the route and change the route. If the rear cabin control display calls the route and changes the route, the display module in the rear cabin control display displays "no authority, call failed / change failed";

[0032] When the authority switch switches the control to the rear cabin, the cabin / rear cabin related staff can observe the route tracking situation and call the route, so that the autopilot system controls the aircraft to fly according to the route called by the display module in the rear cabin control display. Specifically, when the control is in the rear cabin, the display module in the rear cabin control display calls the waypoints and route information of the data storage modules in the front and rear cabin control displays, and has the authority to call the route and change the route. After the call is successful, the display modules of the front and rear cabin control displays synchronously display the results of calling and changing the current route; at this time, the front cabin does not have the control authority, and the front cabin control display does not have the authority to call the route and change the route. If the front cabin control display calls the route and changes the route, the display module in the front cabin control display displays "No authority, call failed / change failed";

[0033] like Figure 3 As shown, the real-time position information of the aircraft is obtained through the inertial navigation computer, the inertial navigation computer receives the route information from the data storage modules of the front and rear cabin control displays, and compares the real-time position information of the aircraft with the route information to obtain the deviation between the real-time position of the aircraft and the route. The inertial navigation computer transmits the deviation result to the autopilot system, and the autopilot system automatically controls the aircraft to fly according to the planned route.

[0034] like Figure 4 As shown, the autopilot system automatically controls the aircraft to fly along the planned route, and the cabin / rear cabin related staff observe the deviation between the aircraft's real-time position and the route through the display module in the rear cabin control display. When the deviation value is greater than the set threshold, the autopilot system automatically controls the aircraft to fly, and continuously reduces the deviation from the route until the deviation value is less than the set threshold. The autopilot system automatically controls the aircraft to fly along the planned route, thereby realizing the aircraft's automatic navigation function.

[0035] like Figure 5 As shown, when the deviation value is less than the set threshold, the cabin / rear cabin staff use the heading hold function in the autopilot system to control the aircraft to further reduce the deviation between the aircraft's real-time position and the planned route until the mission requirements are met, thereby realizing the route deviation correction function.

[0036] The system and method of the present invention are used on a certain type of aircraft, and the products involved include: authority switch, front cabin control display, rear cabin control display, autopilot system. The peripheral equipment involved includes inertial navigation computer, integrated display, etc. The system of the present invention has the following functions:

[0037] (1) Route planning authority management

[0038] The aircraft cockpit (front cabin) is provided with an authority switch and a front cabin control display; the aircraft cabin (rear cabin) is provided with a rear cabin control display. The authority switch is integrated on the front cabin control display and is controlled by the pilot in the cockpit (front cabin).

[0039] The front cabin control display and the rear cabin control display both include a waypoint editing module, a route planning module, a storage module and a display module.

[0040] The waypoint editing module is used to edit waypoints in the front cabin control display and the rear cabin control display; the route planning module is used to plan routes in the front cabin control display and the rear cabin control display; the storage module is used to store the waypoints and planned routes edited by the front cabin control display and the rear cabin control display; the display module is used to call and display the waypoints and route information in the storage module.

[0041] The front cabin waypoint editing module and the rear cabin waypoint editing module are independent of each other. The front cabin control display and the rear cabin control display can edit waypoints independently without being interfered by the other control display.

[0042] The front cabin route planning module and the rear cabin route planning module are independent of each other. The front cabin control display and the rear cabin control display can plan routes independently without being interfered by the other control display.

[0043] The front cabin data storage module and the rear cabin data storage module are independent of each other. The waypoints edited by the waypoint editing module and the route planning module in the front cabin control display and the planned routes are stored in the front cabin data storage module; the waypoints edited by the waypoint editing module and the route planning module in the rear cabin control display and the planned routes are stored in the rear cabin data storage module.

[0044] The functions of calling and displaying waypoints and route information of the front cabin display module and the rear cabin display module are affected by the permission switch. In addition, the front cabin display module and the rear cabin display module have the function of synchronous display. The specific performance is:

[0045] When the authority switch is switched to the "rear cabin" position, the front cabin control display and the rear cabin control display both highlight the control authority to the driver and navigator in the "rear cabin". At this time, the route planning of the rear cabin control display is valid, that is, the rear cabin control display has the authority to call waypoints and routes, and can call waypoints and routes in the storage module. After the call is successful, the front cabin and rear cabin control displays will synchronously display the called waypoints and routes on the map screen. At this time, if the front cabin control display calls the waypoints and routes of the storage module, the front cabin control display will prompt "No authority, call failed".

[0046] When the authority switch is switched from "rear cabin" to other positions, the front cabin control display and the rear cabin control display both highlight the control authority to the driver and navigator in the "front cabin". At this time, the route planning of the front cabin control display is valid, that is, the front cabin control display has the authority to call waypoints and routes, and can call waypoints and routes in the storage module. After the call is successful, the front cabin and rear cabin control displays will synchronously display the called waypoints and routes on the map screen. At this time, if the rear cabin control display calls the waypoints and routes of the storage module, the rear cabin control display will prompt "No authority, call failed".

[0047] (2) Inertial navigation computer control authority management

[0048] The inertial navigation computer is interconnected with the satellite antenna to analyze satellite signals in real time and obtain the aircraft's real-time position information.

[0049] The inertial navigation computer determines the position of the authority switch in real time. When the authority switch is in the "rear cabin" position, the inertial navigation computer receives the route information from the data storage module of the rear cabin control display, and compares the aircraft's real-time position information with the route information to obtain the deviation between the aircraft's real-time position and the route. When the authority switch is not in the "rear cabin" position, the inertial navigation computer receives the route information from the data storage module of the front cabin control display, and compares the aircraft's real-time position information with the route information to obtain the deviation between the aircraft's real-time position and the route.

[0050] The inertial navigation computer transmits the deviation results such as yaw angle and yaw distance to the front and rear cabin control displays, and the front and rear cabin display modules display them on the map screen for the front cabin pilot and cabin / rear cabin related staff to observe the route tracking situation.

[0051] The inertial navigation computer transmits the deviation results such as yaw angle and yaw distance to the autopilot system. When the front cabin pilot and cabin / rear cabin staff turn on the automatic navigation function of the autopilot system, the autopilot system will automatically control the aircraft to fly according to the planned route.

[0052] (3) Autopilot system control authority management

[0053] The autopilot system can automatically control the aircraft to fly according to the specified attitude and track, and achieve automatic stabilization and control of the aircraft's three-axis attitude angles and the aircraft's spatial position in three directions.

[0054] The autopilot system determines the position of the authority switch in real time. When the authority switch is switched to the "rear cabin" position, the autopilot system controls the aircraft to fly according to the relevant cabin (rear cabin) staff. When the authority switch is switched from "rear cabin" to other positions, the autopilot system controls the aircraft to fly according to the cockpit (front cabin) pilot.

[0055] (4) Cabin (rear cabin) route deviation correction function

[0056] When performing tasks such as aerial photography and aerial surveying, a certain type of aircraft needs to fly along a planned route. By turning on the automatic navigation function, the autopilot system can automatically control the aircraft to fly along the planned route, thereby assisting the crew in completing tasks such as aerial photography and aerial surveying.

[0057] Because the routes are mainly edited and monitored by the navigator in the rear cabin when performing tasks such as aerial photography and aerial surveying, on certain aircraft, cabin (rear cabin) staff also have the authority to control the autopilot. When performing a task, the pilot in the cockpit (front cabin) switches the authority switch to the "rear cabin" position, and the cabin (rear cabin) staff calls the route required for the task, and then turns on the automatic navigation function. At this time, the autopilot system is interconnected with the inertial navigation computer, and receives the deviation data information between the real-time position of the aircraft and the route sent by the inertial navigation computer. When the deviation value is greater than the set threshold, the autopilot system automatically controls the aircraft to fly, continuously reducing the deviation from the route until the deviation value is less than the set threshold. The autopilot system automatically controls the aircraft to fly according to the planned route, realizing the automatic navigation function.

[0058] Due to the limitations of objective conditions such as instrument accuracy and environmental factors, when the autopilot system's automatic navigation function is turned on and the aircraft is controlled to fly along the planned route, there will inevitably be a steady-state deviation between the aircraft's actual flight path and the planned route. Steady-state deviation usually does not affect the achievement of flight missions. However, in some cases, users hope to further reduce steady-state deviations to improve mission completion.

[0059] Cabin / rear cabin staff can observe the deviation between the aircraft's real-time position and the route through the display module in the rear cabin control display. When the deviation value is less than the set threshold, cabin / rear cabin staff can use the heading hold and other functions in the autopilot system to manipulate the aircraft to further reduce the deviation between the aircraft's real-time position and the planned route until the mission requirements are met. At this time, cabin / rear cabin staff exit the heading hold and other functions and resume the automatic navigation function. The autopilot system will control the aircraft to maintain automatic navigation with a small deviation, realizing the cabin (rear cabin) route deviation correction function.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the field can easily think of various equivalent modifications or substitutions within the technical scope disclosed by the present invention, and these modifications or substitutions should all be covered within the protection scope of the present invention.
