Description
Technical Field
The present invention relates to an automatic flight control technology of an aircraft, and in particular, to an interactive control of an automatic flight system of an aircraft, and in particular, to a flight mode control device and a flight mode control method for an aircraft, and an aircraft including the flight mode control device.
Background
The automatic flight system is one of the core control systems of modern aircraft and one of the most frequent human-computer interaction functional systems in the various systems of the aircraft. Presently, pilots primarily perform interactive control related to automatic flight systems via control devices such as flight mode control panels, typically located in the middle of the hood of the cockpit, which in some existing implementations are used for simultaneous manipulation or use by left/right pilots.
For example, the control functions or control modes of the flight mode control panel as described above can be generally classified into four categories: system management (including such things as switching on/off of APs, ATs, FDs, selection of the main FMS (FMS i.e. flight management system), selection of true magnetic heading/barometric reference, etc.); vertical mode control; horizontal mode control; and (4) controlling the speed. Wherein, AP is called Auto Pilot, namely an automatic driving system; AT is called Auto Throttle system; FD is collectively called Flight Director, i.e., a Flight guidance system.
In the airplane type widely adopted at present, a mode of combining a traditional display window and a hardware control device is adopted. However, such designs generally require a relatively large number of hardware control devices, which makes the overall design of the interactive control scheme of the automatic flight system relatively inflexible, with many limitations in terms of interfaces, device layout, etc., and with less intuitive control of the maneuvers required by the pilot.
In other prior art, the concept of touch control is applied. However, since the aircraft is not always in a very stable flight state during the flight process, when the flight state is not very stable, the touch control method is relatively easy to cause a malfunction. This entails a certain deficiency or risk in the safety of the system for such core control systems as the interactive control of the automatic flight system.
Therefore, it is desirable to provide a new flight mode control device and a flight mode control method associated with an automatic flight system of an aircraft, so as to at least partially alleviate or compensate the above-mentioned disadvantages of the prior art, and to provide a flight mode control method that is friendly and convenient to operate and provides high system safety.

The flight mode control device comprises a touch display device 1, a physical control device and a channel controller 5. Typically, the physical manipulation means may comprise, for example, a knob 21, a push-button switch 22 (i.e., a push button).
The touch display device 1 is in operable communication connection with the automatic flight system 3 via a first channel, and is configured to be capable of displaying an interactive interface for an operator to control the operation of the automatic flight system 3, wherein the touch display device 1 is further configured to be capable of generating a first type of control instruction in response to a touch operation, and sending the first type of control instruction to the automatic flight system 3 to control the operation thereof.
And the physical manipulation device is in operative communication with the automatic flight system 3 via a second channel, which is independent of the first channel, and is configured to be able to generate a second type of control instruction in response to the physical manipulation and to send the second type of control instruction to the automatic flight system 3 to control its operation.
It will be understood that the rotation adjustment function of the knob 21 and the push control function of the push selector switch 22 may be integrated on the same operating device, i.e., an operating device may be designed which is responsive to a rotation operation or a push operation thereof by the pilot. A preferred physical actuation means may be embodied by a device comprising two layers of inner and outer knobs 21 and a push selector switch 22 integrated on the inner knob 21. For example, the pilot can select the control parameter to be adjusted by the external knob 21, adjust the value of the selected control parameter by the internal knob 21, and press the selection switch 22 for confirmation of the operation. It is to be understood that in the embodiments described below in connection with the rotary knob 21 or the push-on selector switch 22, the rotary knob 21 or the push-on selector switch 22 may generally be replaced by the integrated operating device described above.
In the flight mode control device, the passage controller 5 is configured to be able to selectively disable the first passage or the second passage. In this way, it is possible to selectively control the operation of the automatic flight system 3, or to carry out operations related to the control of the flight mode, according to different conditions or situations, using only the manoeuvre mode that is more suitable for the current conditions or situations.
According to the above scheme, the pilot can perform control operation of the flight mode, such as selection of the flight mode, and numerical adjustment of speed, altitude, heading and the like, through the touch display device 1 or through a physical control device. For example, the crew member can perform intuitive interaction with the touch screen, and can perform more reliable and faster operation with the knob 21 to avoid the risk of misoperation. In the case where one of the two control methods or two channels fails or is not suitable for performing a control operation in the current state, a backup operation may be performed using the other. It should be understood that the automatic flight system 3 further performs corresponding operations on the flight control system 4 according to the control instruction or control information of the pilot, wherein the association between the automatic flight system 3 and the flight control system 4 may follow various configurations, which is not described herein.
According to some preferred embodiments of the present invention, the physical manipulation device is in communication connection with the touch display device 1, and the touch display device 1 is further configured to be able to obtain a first type of control instruction generated by the physical manipulation device and update the displayed interactive interface according to the first type of control instruction. Therefore, no matter the physical manipulation device or the touch display device 1 is used for manipulation, the relevant operation information can be displayed on the display interface in real time.
According to some preferred embodiments of the present invention, the channel controller 5 comprises a flight status monitoring device configured to be able to acquire flight status parameters of the aircraft, the channel controller 5 being configured to be able to selectively disable the first channel or the second channel depending on the acquired flight status parameters.
It is further preferred that the channel controller 5 comprises vibration monitoring means configured to enable a vibration parameter of the aircraft to be obtained, the channel controller 5 being configured to disable the first channel when the obtained vibration parameter exceeds a preset vibration parameter threshold, while only allowing control of the operation of the automatic flight system 3 by the second channel via, for example, the knob 21, pressing the selector switch 22. The vibration parameters mentioned herein may for example comprise vibration frequency and/or vibration amplitude. The detection of the vibration parameter may for example be provided by a vibration detection sensor integrated inside the flight mode control device.
According to the above-mentioned solution, for example, when the aircraft has a significant bump due to factors such as disturbance of air flow during the flight of the aircraft, the channel controller 5 can automatically determine that the current flight state may be relatively unfavorable for the touch operation mode, and to avoid the misoperation caused by the touch operation mode, the first channel is automatically disabled, or the operation of the automatic flight system 3 is automatically disabled by performing the touch operation on the touch display device 1.
Referring to fig. 2, according to some preferred embodiments of the present invention, the knob 21 or button is arranged with a strip of edge indicator light 23, the strip of edge indicator light 23 being configured to be illuminated when the first channel is disabled, so as to alert the pilot that the tactile means has been turned off.
According to some preferred embodiments of the present invention, the physical manipulation device is communicatively connected to the channel controller 5, and the physical manipulation device is further configured to be able to instruct the channel controller 5 to disable the first channel or to release the disabling of the first channel in response to a preset first touch operation. I.e. to resume use of the previously disabled or disabled first channel. Further preferably, the first touch operation is set to press the knob 21 or the button for a preset first duration.
Referring to fig. 2-3, according to some preferred embodiments of the present invention, the touch display device 1 includes a display screen having a plurality of display areas for displaying a plurality of interactive sub-interfaces, respectively, each of which is associated with a type of operation of the automatic flight system 3. And, a knob 21 or a button is disposed at the edge of each display area.
Fig. 3 shows a specific example of a display interface of the touch display device 1, in which a plurality of graphic regions 11 are included. It is understood that the display interface containing the plurality of graphic areas 11 in the present invention may adopt an interface layout substantially consistent with the PFD interface currently in the mainstream. Therefore, the display interface can also be used as a standby display channel in the case of PFD failure. The PFD is called Primary Flight Display, and the PFD interface is the main Flight Display interface.
As shown in fig. 3, in this specific implementation, the display interface is divided into five graphic zones 11, the first graphic zone 11 is a speed mode selection and adjustment zone, the second graphic zone 11 is a heading track mode selection and adjustment zone, the third graphic zone 11 is a main mode control zone (including AT, AP, APPR, etc.), the fourth graphic zone 11 is a height mode selection and adjustment zone, and the fifth graphic zone 11 is a vertical speed/track mode selection and adjustment zone. Wherein, the APPR is fully called Approach, namely the Approach mode.
The rectangular boxes distributed over the various graphics areas 11 represent controls for selection, such as mode selection or speed/mach number, which can be interacted with by finger touch, or can be selected by means of knobs 21 arranged at the lower edge of the display interface. The graphical zone 11 may be customized according to the actual designed graphical interfaces of speed, altitude, heading, etc., which may be designed to correspond well with the PFD interface in order to improve the intuitiveness of the display interface. Each graphics field 11 may also be subject to numerical adjustments such as speed, heading, altitude, heading track, etc., which may be manipulated in particular by touch, slide or knob 21 controls.
According to some preferred embodiments of the present invention, during normal cruise conditions, when the aircraft is in a stable control state, such as speed in SPD mode (i.e., speed mode), heading in HDG mode (i.e., heading mode), AT on, AP on, altitude hold 23000, level flight, only the current mode and value indication may be displayed in the display interface, with no other mode controls operable, such as shown in fig. 4. The displayed content can be more concise and intuitive, and the pilot can clearly judge the current flight state conveniently.
A flow example of a flight mode control method to which the flight mode control apparatus according to the above preferred embodiment of the present invention is applied will be briefly described below with reference to fig. 5.
The pilot brings the flight mode control device into an active state by approaching, for example, a control panel or a touch screen. And judging whether the vibration parameters exceed a preset vibration parameter threshold value or not by monitoring the vibration parameters of the airplane.
In the event of an overrun, the first channel is disabled, allowing control of the operation of the automatic flight system 3 only by physical handling means such as the knob 21, i.e. enabling the full knob 21 control mode, which would otherwise allow operation in both of the aforesaid handling modes.
And optionally the first channel may be disabled manually by long pressing of the knob 21 or the like, thereby allowing only control of the operation of the automatic flight system 3 by physical manipulation means such as the knob 21.
While specific embodiments of the invention have been described above, it will be appreciated by those skilled in the art that these are by way of example only, and that the scope of the invention is defined by the appended claims. Various changes and modifications to these embodiments may be made by those skilled in the art without departing from the spirit and scope of the invention, and these changes and modifications are within the scope of the invention.
