Description

Cockpit interaction system of an aircraft and associated interaction method

The present invention relates to an interaction system of the cockpit of an aircraft.

The present invention also relates to an associated interaction method.

The field of the invention is the field of aeronautics, and more particularly the field of visualizations low heads flying aircraft.

In a manner known per se, the mission of the crew of the aircraft requires a multitude of data from very different systems. This often implies the need to ensure effective and rapid interactions between these different systems and between the crew and these systems. The last type of interaction is known as "man-machine interaction".

Among the systems that can be used by the crew in the cockpit, there are notably systems, known as avionics, such as for example a flight management computer, and so-called open world systems, such as for example an EFB tablet. (English "Electronic Flight Bag" or "Electronic Flight Bag" in French).

The applications implemented by avionic systems are subject to certification and must demonstrate the availability and integrity necessary for the function they perform and the consequences of loss or error of these functions.

Other functions necessary for the preparation of the mission, maintenance tasks, data receptions (weather for example), do not have the same constraints and are therefore developed in the open world to reduce their cost. Some applications on EFB tablets are available on the market to meet this growing need.

However, for security reasons, open world systems can not support the functions of avionics systems. Indeed, these systems of the open world are often completely segregated systems of the avionics world so that they can not interfere with the operation of these systems.

When the use of both worlds systems is required in the cockpit, known methods of the state of the art often provide the crew to use these systems separately, for example by performing a separate data entry in each of the systems. It is conceivable that these methods increase the cognitive load provided by the crew.

In addition to the problems of interaction between the systems of the avionic world and the open world, there are problems in human-machine interactions especially when it comes to the systems of the avionics world. Indeed, the man-machine interactions with the systems of the avionics world are usually done directly via control means dedicated to these systems such as for example different types of keyboards and sliders. These control means are generally fixedly adapted to the ergonomics of the cockpit and to a reference position of the pilot. However, since the position of the pilot evolves according to particular phases of flight, the interactions with these control means can pose difficulties.

To at least partially solve the problem of interaction between the systems of the avionics world and the open world, there is known a method proposed by EP 2 165 156 B1 for displaying a stream of images from a system of the world open on one or more avionics screens.

This method makes the use of this system of the open world simpler but does not entirely solve the problem of interaction between the systems of the avionic world and the open world. In addition, this method does not make man-machine interactions more flexible.

The present invention aims to ensure the interactions between the open world systems and the avionics world of the cockpit of an aircraft, while simplifying man-machine interactions including systems of the avionics world.

To this end, the invention relates to a cockpit system of an aircraft comprising a secure avionics equipment having a plurality of modifiable configurations; a remote tablet of the avionics equipment and movable relative thereto, the tablet being able to generate digital data comprising data for modifying at least one configuration of the avionic equipment; and exchange means adapted to transmit the digital data generated by the tablet to the avionics equipment to modify the corresponding configuration thereof.

According to other advantageous aspects of the invention, the system comprises one or more of the following characteristics, taken separately or in any technically possible combination:

- The avionics equipment is able to further generate digital data and / or an image stream for the tablet;

the exchange means are able to further transmit the digital data and / or the stream of images generated by the avionic equipment to the tablet;

the tablet comprises an application module configured to generate the digital data intended for the avionic equipment and to receive the digital data derived therefrom; the avionic equipment comprises an application module configured to generate the digital data intended for the tablet and to receive the digital data derived therefrom;

the operation of the application modules of the avionics equipment and the tablet is synchronized permanently or temporarily;

the tablet comprises a display screen capable of displaying images originating from the stream of images transmitted from the avionic equipment via the exchange means;

the tablet has a plurality of modifiable configurations;

the tablet comprises a processing module able to modify at least one configuration of the tablet according to interaction data;

the avionic equipment comprises an interaction module capable of generating interaction data following actions exerted by a user on the avionic equipment, the digital data transmitted from the avionic equipment to the tablet via the means of communication; exchange correspond to these interaction data;

- The avionics equipment includes a display screen adapted to display images from a stream of images;

the tablet includes a processing module able to generate an image flow, the exchange means being able to transmit the image flow generated by the tablet to the avionics equipment;

the system comprises interruption means able to activate or deactivate the operation of the exchange means; and

the tablet is formed by an electronic device such as an electronic flight bag or an avionics tablet.

The present invention also relates to a tablet of the system as defined above, used as a remote control of the avionics equipment of this system. The present invention also relates to an interaction method implemented by an interaction system comprising a secure avionic equipment having a plurality of modifiable configurations, a remote tablet of the avionic equipment and mobile relative thereto, the tablet being able to generate digital data comprising data for modifying at least one configuration of the avionic equipment, and exchange means.

The method comprises the transmission by the exchange means of the digital data generated by the tablet to the avionics equipment to modify the corresponding configuration thereof.

These features and advantages of the invention will become apparent on reading the description which follows, given solely by way of nonlimiting example, and with reference to the appended drawings, in which:

FIG. 1 is a schematic view of an interaction system according to a first embodiment of the invention; and

FIG. 2 is a schematic view of an interaction system according to a second embodiment of the invention.

The interaction system 10 of FIG. 1 can be used in the cockpit of an aircraft by the crew of the latter.

By aircraft, it is understood any controllable craft to fly in particular in the Earth's atmosphere, such as an airplane, a helicopter, a drone, etc.

By cockpit of this aircraft, it is understood the place from which the piloting of the aircraft takes place. The cockpit is disposed inside the aircraft in a manner known per se or is deported from the aircraft. In the latter case, it is in particular a remote pilot center remotely performing the piloting of the aircraft as is particularly the case of a drone.

By aircraft crew, we understand one or more pilots operating the aircraft from the cockpit. When the crew is composed of several pilots, the notion "pilot" used by the following description relates to one of these pilots, preferably to the pilot operating directly the interaction system according to the invention.

With reference to FIG. 1, the interaction system 10 comprises an avionic equipment 12, a shelf 13 remote from the avionics equipment 12, and means 14 for exchanging digital data and image streams between the avionics equipment. 12 and the tablet 13.

The avionic equipment 12 has for example an onboard avionics system known per se or an association of such systems. In the example described, the avionic equipment 12 has a flight plan planning device such as a flight management system of the FMS type (known as the "Flight Management System") known per se.

The avionic equipment 12 comprises an interaction module 21, a processing module 22, an image buffer 23 and a display screen 24.

The avionic equipment 12 has a plurality of modifiable configurations. By modifiable configuration, any operating parameter of this equipment that is capable of being modified in order to modify the operation of the avionic equipment 12 is understood.

These configurations are for example stored in a suitable form in a storage module 26 of this equipment 12, also visible in FIG.

The interaction module 21 is a device control member 12 by the pilot. It is thus in the form of a known keyboard or a pointing device such as a mouse also known per se.

As a result of an action exerted by the crew on the interaction module 21, it is able to generate interaction data describing this action.

The display screen 24 has for example one of the avionics screens cockpit of the aircraft, known per se. This screen is able to display a stream of images from the image buffer 23.

The processing module 22 makes it possible to control the operation of the equipment

12.

The processing module 22 is for example at least partially in the form of software executable by a processor of the avionic equipment 12 and stored for example in a memory provided for this purpose in this equipment 12.

According to another exemplary embodiment, the processing module 22 is at least partially in the form of a programmable circuit.

In particular, the processing module 22 makes it possible to control the operation of the equipment 12 by modifying one or more configurations of this equipment as a result, for example, of receiving interaction data from the interaction module 21.

The processing module 22 furthermore makes it possible to generate images to form a stream of images and to transmit this stream of images to the buffer 23 for display on the display screen 24. The images of this stream illustrate for example, the operation of the avionic equipment 12 and / or the modifications of its configurations.

The tablet 13 is in particular a touch pad from the open world and known in itself. This tablet 13 is mobile in the cockpit. In the example described, the tablet 13 is an EFB tablet that can be used by the pilot to construct a flight plan.

This tablet 13 has a plurality of modifiable configurations to control its operation.

These configurations are for example stored in a suitable form in a storage module 36, also visible in FIG.

In a similar way to the equipment 12, the tablet 13 comprises an interaction module 31, a processing module 32, an image buffer 33 and a display screen 34.

The display screen 34 is for example a touch display screen capable of displaying images of a stream of images from the image buffer 33.

The interaction module 31 has, for example, tactile sensors integrated in the touch screen 34. These sensors are capable of generating interaction data following a tactile movement exerted by the pilot on the touch screen 34. The interaction data thus generated describe this tactile movement.

The processing module 32 controls the operation of the tablet 13.

As in the previous case, the processing module 32 is at least partially in the form of software executable by a processor of the tablet 13 and stored in a suitable memory. As a variant, the processing module 32 is at least partially in the form of a programmable circuit.

The processing module 32 controls the operation of the tablet 13 by modifying one or more configurations of this tablet 13.

The processing module 32 furthermore makes it possible to generate images to form a stream of images. These images illustrate, for example, the operation of the tablet 13 and / or the modifications of its configurations.

According to one embodiment, the tablet 13 further comprises a mechanical support arranged for example fixedly or movably in the cockpit.

This support makes it possible in particular to fix the tablet 13 in a position desired by the driver and to connect it to a power source and possibly to a computer network as will be explained later.

The exchange means 14 are in the form of two transmission channels 42, 43 between the tablet 13 and the equipment 12.

These transmission channels 42, 43 are for example formed by a wired or wireless computer network established between the equipment 12 and the tablet 13 possibly passing through the support when the tablet 13 is equipped with it. The wired network may be formed by copper cables and / or optical fiber.

Those skilled in the art will therefore easily understand that the exchange means 14 may have a wired network when the tablet 13 is placed on the support and a wireless network (WiFi type for example) when the tablet 13 is removed from it. this. The switching between the two types of networks is done for example automatically when the tablet 13 is placed on the support or removed from it.

According to the first embodiment of the invention, one of the transmission channels, for example the channel 43, makes it possible to transmit interaction data from the interaction module 31 of the tablet 13 to the interaction module 21 avionics equipment 12.

The other transmission channel, namely the channel 42, makes it possible to transmit an image stream generated by the processing module 22 of the avionic equipment 12 to the image buffer 33 of the tablet 13.

In this case, the image buffer 33 of the tablet 13 comprises a suitable type of mixer for mixing a stream of images from the equipment 12 and a stream of images generated by the processing module 32 of the tablet 13 to display for example simultaneously the two streams on the display screen 34 of the tablet 13. This mixture is performed for example point by point, without exchange of digital data.

Finally, according to an exemplary embodiment, the exchange means 14 comprise interrupt means able to activate or deactivate the operation of these exchange means 14.

The means of interruption are for example in the form of a physical button allowing the pilot to activate or deactivate the transmission of digital data and / or image flow through one and / or the other transmission channels 42, 43.

The interaction method in the cockpit implemented by the interaction system 10 will now be explained.

Initially, the operation of the exchange means 14 is deactivated.

When it is necessary to establish a data exchange and / or image flow between the tablet 13 and the equipment 12, the pilot activates, during an initial step of the method, the operation of the exchange means 14 via for example the button associated with these exchange means 14.

Then, in a next step, the processing module 22 of the equipment 12 transmits via the transmission channel 42, a stream of images to the image buffer 33 of the tablet 13. This image stream is transmitted for example simultaneously to the buffer 23 of the avionics equipment 12 which displays it on the display screen 24 of this equipment 12.

The stream of images transmitted to the tablet 13 is optionally mixed with a stream of images generated by the processing module 32 of this tablet 13 and is displayed on the display screen 34 of this tablet 13.

In a next step, the driver exerts an action on the interaction module 31 of the tablet 13 which then generates interaction data describing this action.

In particular, when it is a touch pad, the action exerted by the driver corresponds to a movement exerted by the driver on the display screen 34 of this tablet which displays the flow of images from the screen. equipment 12.

The interaction data generated by the interaction module 31 of the tablet 13 are then transmitted via the transmission channel 43 to the interaction module 21 of the avionic equipment 12 which then transmits them to the processing module 22 of this device. equipment 12.

The processing module 22 analyzes the received interaction data and modifies according to these data at least one configuration of the equipment 12. It then generates a corresponding image stream which is transmitted again to the tablet 13.

It is then conceivable that the interaction system 10 according to the first embodiment makes it possible to use the tablet 13 as a remote control of the avionic equipment 12.

This use of the interaction system 10 is particularly advantageous when the aircraft is in the cruising phase. Indeed, in this phase, the position of the pilot's seat is generally set back compared to the avionics screens, which makes direct interaction with control organs associated with these screens difficult.

In this case, the tablet 13, because of its mobility, has a greater flexibility than the control organs associated with the avionics screens and can be used with its support or without it even when the pilot is moved away from the avionics screens.

This allows in particular to display the pilot information on the flight while giving a possibility to control the avionics equipment 12 without changing its position.

This control of the avionic equipment 12 can vary from a simple change of the display to a modification of an avionics function.

In addition, the interaction system 10 provides the necessary security for the avionics equipment 12 because only interaction data are transmitted thereto.

The interaction data can be of different natures. According to an advantageous embodiment of the invention, the interaction data comprises a so-called "zoom" operation corresponding to the enlargement or decrease of the image displayed on the tablet. For example, in this case, the stream of images transmitted by the avionics equipment to the tablet includes a map or a flight plan. The crew can therefore exercise the zoom operation on the tablet and the corresponding interaction data are transmitted to the avionics equipment. Then, these data are processed by the equipment which then determines that it is a zoom operation and returns to the tablet a stream of images corresponding to an enlarged or diminished map or flight plan ( e).

This first embodiment of the invention may be completed by other advantageous features of the invention.

Thus, according to an exemplary embodiment of this mode, the exchange means 14 comprise in addition to the two transmission channels 42, 43 described above, two other transmission channels between the equipment 12 and the tablet 13.

One of these channels is adapted to transmit interaction data from the interaction module 21 of the avionics equipment 12 to the processing module 32 of the tablet 13, and the other channel is adapted to transmit a stream image generated by the processing module 32 of the tablet 13 to the image buffer 23 of the avionic equipment 12.

In this case, the image buffer 23 of the equipment 12 comprises a mixer of suitable type and making it possible to mix a stream of images coming from the tablet 13 and a stream of images generated by the processing module 22 of this device. equipment for displaying for example simultaneously the two streams on the display screen 24 of this equipment. As in the previous case, this mixture is for example point by point, without digital data exchange.

In addition, the interaction data transmitted from the equipment 12 to the tablet 13 make it possible to remotely modify at least one configuration of the tablet 13.

It is conceivable that these advantageous features of the invention can further control the operation of the tablet 13 from the equipment 12 and display on the display screen 24 of the avionics equipment 12 data from the world such as information relating to the airline or cabin, or information from an EFB tablet.

This use of the interaction system 10 makes it possible to display and interact with the tablet 13 while ensuring the necessary security and segregation of the avionic equipment 12. According to this embodiment, no data transmission functional only to the avionics equipment 12, only the image flows and interaction data from the open world that can reach this equipment.

An interaction system 1 10 according to a second embodiment will now be described with reference to FIG.

This interaction system 1 10 is substantially similar to the interaction system 10 according to the first embodiment of the invention.

In particular, as in the previous case, the interaction system 1 10 comprises an avionic equipment 1 12, a shelf 1 13 remote from the avionic equipment 1 12 and exchange means 1 14 between the avionic equipment 1 12 and the tablet 1 13.

As in the previous case, the avionic equipment 1 12 comprises an interaction module 121, a processing module 122, an image buffer 123 and a display screen 124 which are analogous to the interaction module 21, respectively. the processing module 22, the image buffer 23 and the display screen 24 described above.

Similarly, the tablet 1 13 comprises an interaction module 131, a processing module 132, an image buffer 133 and a display screen 134 which are respectively analogous to the interaction module 31, to the processing module 32, the image buffer 33 and the display screen 34 described above.

Unlike the avionics equipment 12 and the tablet 13 previously described, each of the avionics equipment 1 12 and the tablet 1 13 further comprises an application module 125, 135.

Each of these application modules 125, 135 is for example in the form of software executed by a processor respectively of the avionics equipment 1 12 and the tablet 1 13, and is capable of generating and processing functional data relating to to the operation respectively of this equipment 1 12 or of this tablet 1 13.

These application modules 125, 135 are for example substantially similar and allow to implement substantially identical functions. In this case, the operation of these modules 125, 135 can be synchronized as will be explained later.

The application module 125 of the avionic equipment 1 12 is able to communicate with the processing module 122 of this equipment 1 12 to modify at least one configuration thereof. Similarly, the application module 135 of the tablet 1 13 is able to communicate with the processing module 132 of the tablet 1 13 to modify at least one configuration thereof.

As in the previous case, the exchange means 1 14 are in the form of two transmission channels 142, 143 between the shelf 1 13 and the equipment 1 12.

These transmission channels 142, 143 are for example formed by a wired or wireless computer network established between the equipment 1 12 and the tablet 1 13 possibly passing through the support when the tablet 1 13 is equipped with it.

According to the second embodiment, the exchange means 1 14 allow exchanges of functional data between the application modules 125, 135 of the avionic equipment 1 12 and the tablet 1 13.

In particular, in this case, one of the transmission channels, for example the channel

142, allows the transmission of functional data from the application module 125 of the avionic equipment 1 12 to the application module 135 of the tablet 1 13 and the other channel, namely the channel 143, allows the transmission of functional data in the direction reverse.

To secure the exchanges, the exchange means 1 14 comprise a secure gateway 144, 145 for example for each of the transmission channels 142,

143. These gateways 144, 145 make it possible to control the conformity of the exchanged functional data with a predetermined secure exchange protocol and then present filters of the functional data transiting via the channels 142, 143.

Finally, as in the previous case, the exchange means 1 14 may comprise interrupt means capable of activating or deactivating the exchanges of the functional data via one of the transmission channels 142, 143 or else, via the two channels 144, 145.

These interruption means are for example in the form of a physical button actuated by the pilot.

The interaction method in the cockpit implemented by the interaction system 1 10 will now be explained.

Initially, the operation of the exchange means 1 14 is deactivated.

When it is necessary to establish a functional data exchange between the application modules 125, 135 of the avionic equipment 1 12 and the tablet 1 13, the pilot activates, during an initial step of the method, the operation of the exchange means 1 14 via for example the button associated with these exchange means.

Then, in a next step, the application module 125 of the avionic equipment 1 12 sends to the application module 135 of the tablet 1 13 functional data. This data then passes through the transmission channel 142 via the secure gateway 144.

If these data comply with the corresponding secure protocol, they are transmitted to the application module 135 of the tablet 1 13.

In another step, implemented in parallel, after or before the previously described step, the application module 135 of the tablet 1 13 sends to the application module 125 avionics equipment 1 12 functional data. This data then passes through the transmission channel 143 via the secure gateway 145.

If this data is in accordance with the corresponding secure protocol, it is transmitted to the application module 125 of the avionic equipment 1 12. This secure protocol may for example have an increased security compared to that of the gateway 144 because the transmission is carried out towards avionics equipment 1 12.

Moreover, when these data transmitted to the avionic equipment 1 12 are intended to change a major configuration of this equipment, such as for example a configuration relating to the mission of the aircraft, the method further comprises an additional step when which the pilot must confirm or reject such a change.

It will be understood that the second embodiment makes it possible to implement functional data exchanges between two application modules, one belonging to the avionics world and the other to the open world.

These application modules can for example be used as software relating to the mission planning of the aircraft.

Thus, for example, the functional data transmitted between the two modules may include the current position of the card, the zoom factor, range, etc.

In addition, the operation of both modules can be synchronized temporarily or permanently.

In this case, these two modules become completely synchronous from the point of view of the pilot. Thus, for example, it is possible to implement a preparation of the flight plan by means of the tablet while seeing it being built in the avionics world simultaneously. If, for example, the pilot zooms on a map displayed on the tablet, the same zoom is transposed on the map displayed on the avionics screen.

Of course, it is possible to mix different types of interaction between the tablet and the avionics equipment described in connection with the first embodiment with those of the second embodiment. Thus, for example, it is possible to simultaneously implement exchanges of interaction data and / or an image flow with functional data exchanges.

Other embodiments also remain possible.
