    System and method for controlling and monitoring equipment of an aircraft
    The present invention relates to a system for controlling and monitoring equipment of an aircraft, each device being able to be switched between at least two logic activation status values.
    Such a system is intended to be used in a cockpit of the aircraft, to facilitate the work of the crew to control the performance of functions during the evolution of the aircraft.
    It can also be implemented by a remote operator of the aircraft.
    To control the equipment of the aircraft, it is usually made available to the crew, especially in the cockpit of the aircraft, a control panel (the majority of orders are grouped in the "upper table" at the top of the aircraft. cockpit), comprising a set of control members, for example control buttons such as switches, each dedicated to a particular piece of equipment. Each control button allows an operator to control the activation of the associated equipment, in particular to select an activation state for this equipment from among the possible activation states, for example a running state, in which the equipment operates in a nominal mode, and a shutdown state.
    The equipment can be grouped by systems. On the one hand, each system may comprise several equipment suitable for jointly performing a particular service or function. On the other hand, an equipment can participate in the realization of more than one function and belong then to several different systems. The crew also has a display device (commonly called "synoptic"), for example one or more screens, on which can be displayed the activation status and / or operation of each of the equipment . Thus, the majority of systems is associated with a window that can display a logic diagram of the system, and the activation status and / or operation of each of its equipment.
    Such a display enables the crew to follow the activation and / or operating state of an equipment, and more generally of the system (s) to which they belong, in response to an action on the command button associated with this equipment.
    Each function can take at least two distinct activation states, for example an activated state, in which the function is active, that is to say in which the equipment of the associated system performs this function, and a deactivated state, in which which the function is inactive.
    To change the activation state of a function, for example to change from the active state to the inactive state or to go from the inactive state to the active state, the crew must perform a series of operations on the equipment of the system associated with the function, according to a predefined procedure. This procedure can be displayed in a window dedicated to all procedures.
    The operations are for example actions to be executed such as commands of all or part of the equipment of the system, by means of the dedicated control buttons (for example arranged on the upper table), and checks, by the operator, of the application of these commands on the display window (or synoptic) associated with the system.
    Thus, to change the activation state of a function, the operator must turn his attention successively to the window showing the procedure to be implemented for this activation or inactivation, then on the control panel, to change the activation state of a device of the system carrying out the function, then on the window associated with this system, to check the taking into account of this command.
    This dispersion of information and commands / monitoring results in an overload of work for the operator, and does not allow him to have a global awareness of the situation, in particular the link between the activation status of the various equipment of the system and the activation status of the associated function.
    In addition, in the event of equipment failure, this fault state may be displayed without the crew being able to know if the function or functions performed by this equipment are affected.
    The known control and monitoring systems are therefore not entirely satisfactory.
    An object of the invention is to provide a control and monitoring system, which makes it possible to manage the equipment of the aircraft in a simplified manner, by providing the pilot with a global awareness of the link between the states of activation and operation of the aircraft. equipment and the states of activation and operation of the functions performed using these devices.

The subject of the invention is also a method for controlling and monitoring equipment of an aircraft, each device being able to be switched between at least two logic activation state values, said control and monitoring method comprising the following successive steps: - selection, by an operator, via a human machine interface, of a functional state of activation of a function to be performed by at least two of the equipment of a system of said aircraft, the functional state of activation of said function being configurable between at least one active state and an inactive state of said function, - detection of the selection of said activation functional state, - determination, from the functional state activation of said selected function, a logic activation state of each of said at least two devices of said system, so that, when each of said at least two devices is in the determined activation logic state, said function is in the selected activation functional state.

The invention will be better understood on reading the description which follows, given solely by way of example, and with reference to the appended drawings, in which: FIG. 1 is a diagram showing a control system and monitoring according to one embodiment of the invention; FIG. 2 is a functional diagram or block diagram associated with a system of an aircraft, intended to be displayed to an operator by the control and monitoring system of FIG. 1, in a first configuration of the equipment of the system ; Figure 3 is a diagram of a method according to an embodiment of the invention; FIG. 4 is a functional diagram or block diagram associated with a system of an aircraft, intended to be displayed to an operator by the control and monitoring system of FIG. 1, in a second configuration of the equipment of the system .
    A system 2 for controlling and monitoring equipment of an aircraft according to one embodiment of the invention is illustrated schematically in FIG.
    This control and monitoring system 2 is for example intended to be mounted in an aircraft, in particular in a cockpit, for the crew of the aircraft. Alternatively, the control and monitoring system 2 may also be located on the ground, in particular in a ground station, and may be intended for the control and monitoring of an aircraft remotely from the ground station.
    The control and monitoring system 2 is intended to allow the management by an operator of functions performed by equipment of the actuator type of the aircraft.
    These actuator type devices form systems. A system comprises a plurality of separate devices capable of jointly performing a particular function.
    These systems are aircraft systems, and include, in particular, energy management systems, for example an electrical system, a fuel management system, a propulsion system, and / or fluid transfer systems, for example a system conditioning ....
    For example, each system can be an air sampling system (BAS for "Bleed Air System" in English), a conditioning system (ECS for "Environmental Control System" in English), an anti-icing system, a pressurization system , an auxiliary power unit (APU for "Auxiliary Power Unit" in English), an electrical system, for example distribution or generation of electrical energy, a dynamic air turbine (RAT for "RAM Air Turbine") or a wiring system, a fire detection system, a fuel transfer system, a hydraulic system, a propulsion system (for example IPPS for "Integrated Power Plant System"), a landing system, a lighting system, an oxygen management system, a water management system, a brake management system.
    Each actuator type equipment can intervene in the realization of several functions, and even belong to two separate systems.
    Each actuator type equipment is a device having a physical impact on the system to which it belongs, this impact depending on the activation state of this equipment.
    Each actuator-type device can indeed be switched between at least two activation logic states, hereinafter called activation states, in particular a state of operation, in which the equipment is active, and a stop state, in which the equipment is inactive.
    In addition, each equipment can operate in a normal operating state, in which the equipment operates or is able to function optimally, in a degraded state of operation, which may correspond to a failure of this equipment, or in a state of operation. lost operation, in which the activation state of the equipment is inactive and can no longer be controlled.
    Each function is performed by several actuator type equipment separate from the system to which this function is attached. In the context of the present application, the term "separate actuator-type equipment" means actuator-type equipment whose activation states can be switched independently of one another.
    In addition, the equipment associated with a function will subsequently be called the equipment suitable for carrying out this function together, and a system associated with a function will be called the system comprising these devices.
    Each function can take at least two activation functional states, also subsequently called activation states, for example an active state, in which the function is performed by the associated equipment, and an inactive state, in which the function is not performed by the associated equipment. The activation state of each function depends in particular on the state of activation and operation of each of the equipment associated with this function.
    The functions are for example energy transfer functions between at least two devices, including electrical transfer functions, hydraulic, fuel, air volumes or mechanical energy transfer.
    In this case, the active state of the function corresponds to an active transfer of energy between at least two devices, while the inactive state of the function corresponds to a lack of energy transfer between these devices.
    Functions may also include storage or energy transformation functions.
    At least some of the functions can operate in a manual mode, wherein the activation state of the function can be manually changed by an operator, and an automatic mode, in which the activation state of the function is changed from automatically by the control and monitoring system 2.
    In addition, each function can operate according to at least two operating states, in particular a normal state (without limitation), and at least one degraded state, for example a degraded state with safety margin, a degraded state without safety margin, also called emergency state, and a lost state. The states of normal and degraded operation can be noted that the function is in the active or inactive activation state. More generally, the activation state of a function and its operating state can be independent of one another.
    In the normal operating state, the function is performed or can be performed in a nominal way, without limitation.
    In a degraded state of operation, the use of the function generates limitations.
    A degraded operating state of a function may result from a failure of equipment participating in this function. In particular, a function can be degraded if one of its equipment is unavailable due to a loss of its resource (eg electrical).
    In addition, each function can be controllable or uncontrollable.
    When the function is controllable, the activation state of the function can be configured from the active state to the inactive state, and vice versa from the inactive state to the active state.
    When the function is uncontrollable, the activation state of the function can not be changed, ie the function is blocked in the active state or the inactive state.
    In particular, a lost operating state of a function is a state in which the function is in the idle state and is not controllable. The activation status and the mode (automatic or manual) of a function are configurable by an operator by means of the man-machine interface 16.
    On the other hand, the operating state (normal, degraded, etc.) and the controllable or uncontrollable character of a function can not be modified by an operator, but are characteristics of the function recognized by the control system 2 and monitoring.
    The control and monitoring system 2 is configured to allow an operator to control the activation status and the manual or automatic mode of the functions of the various systems of the aircraft, and to control accordingly the activation states of the aircraft. equipment associated with these functions.
    The control and monitoring system 2 is also configured to inform the operator of the activation status, the manual or automatic mode, the current operating state, and the controllable or uncontrollable character of these functions.
    The control and monitoring system 2 comprises a central processing unit 10, a display device 12 and a man-machine interface 16.
    The display device 12 comprises a screen 14 and means for processing the graphic information, for example a graphics processor and an associated graphics memory.
    The graphics processor is adapted to process the graphical information stored in the graphics memory and achieve the display on the screen 14 of this information or a representation thereof. The man-machine interface 16 is intended in particular to enable control of the activation status and mode of the various functions associated with the systems by an operator, for example a member of the crew of the aircraft. The man-machine interface 16 comprises for example a tactile control device, configured to detect the position of one or more members, hereinafter referred to as control members, on a surface of this tactile control device.
    In known manner, these control members may be a stylet or the fingers of an operator.
    In the remainder of the description, an embodiment will be considered in which this touch control device and the screen 14 have a common shape, in the form of a touch screen.
    Thus, the man-machine interface 16 is configured to detect the position of one or more control members on the surface of the screen 14.
    Some touch control device technologies make it possible to detect the position of control members without there being a contact between the control member and the surface of the tactile control device. Subsequently, the expression "on" a surface or "on" a screen shall be understood to mean "on or near" that surface or screen. The central processing unit 10 is adapted to execute applications necessary for the operation of the control and monitoring system 2. The central processing unit 10 comprises for this purpose a processor 18 and one or more memories 20.
    The processor 18 is adapted to execute applications contained in the memory 20, in particular an operating system allowing the conventional operation of a computer system.
    The memory 20 comprises different areas of memory containing in particular information relating to the various systems of the aircraft and applications intended to be executed by the processor 18.
    The information relating to the systems of the aircraft include in particular, for each system, information relating to the equipment of this system, in particular the states of activation and operation possible for each of these devices.
    This information also includes, for each function that can be performed by a system, at least one procedure for changing the activation status and / or the mode of this function.
    Each procedure generally comprises a series of operations implemented on one or more equipment of the system associated with the function, with a view to modifying the activation state and / or the mode of the function.
    This series of operations generally includes commands for modifying states of activation of the equipment, followed by verification of the application of these commands.
    This series of operations is usually ordered.
    The memory 20 includes a display application, intended to allow an operator to track and / or control the activation status, the operating state and the mode of the functions of the aircraft systems.
    The memory 20 furthermore comprises a configuration application 40 capable of detecting an action of selection of an activation state and / or a mode of these functions by an operator.
    The memory 20 further comprises a control and monitoring application 44, configured to monitor and control the equipment of the systems, in particular in response to a command from an operator. The display application, hereinafter referred to as a display module 30, is configured to control the display, on a dedicated window of the screen 14, for each system, of a functional block diagram representative of this system.
    In particular, this functional block diagram comprises, for each function proper to be performed by the system, an object representative of the activation state and the current mode of this function.
    Each object includes for example an icon representative of the function and one or more symbol (s) or alphanumeric indication (s) associated with this icon.
    Each function is represented on this functional block diagram by an object having at least a first attribute, indicative of the current activation state of the function.
    This object has at least one second attribute indicative of the mode of the function and / or at least one third attribute indicative of the operating state of the function and / or at least one fourth attribute indicative of the controllable or uncontrollable character. of the function. Displaying such attributes limits the interpretation needed to raise awareness of the situation, and thus allows the operator to quickly become aware of the situation.
    In particular, in the event of equipment failure, the display module 30 is able to signal the function or functions that no longer function in a normal operating state as a result of this failure, which enables the operator to visualize directly which functions are impacted, thus limiting the workload for the operator.
    A degraded, backed up or lost operating state of a function can be signaled when the function is active or when the function is inactive.
    The signaling of a degraded state of operation, of backup or lost of a function, when this function is active, allows an operator to take note of the fact that this function can induce limitations because it is incompletely realized.
    The signaling of a degraded state of operation, of backup or lost of a function, when this function is inactive, makes it possible to inform an operator that the function could induce limitations because it would be incompletely realized if it had to be activated, or can not be activated. Such a signaling allows an operator to anticipate future malfunctions of a function.
    Moreover, when a function is uncontrollable, for example blocked in the active state or in the inactive state, the signaling of this uncontrollable character allows the operator to anticipate a future lack of response from the system following a command to change the activation state of the function.
    As described in more detail below in the context of an example, a power transfer function is for example represented on the functional block diagram by an arrow symbolizing this energy transfer.
    The first attribute, indicative of the current activation state of the function, is then for example a color of the arrow and / or a type of arrow pattern, and / or an alphanumeric indication displayed next to the arrow and whose content and / or type of display depends on the current activation state of the function.
    The second attribute, indicative of the mode of the function, and the fourth attribute, indicative of the controllable or uncontrollable character of the function, are for example alphanumeric indications.
    When the energy transfer function is active, the arrow is for example represented by a solid line or by a dashed line, in particular of green color.
    According to this example, when the energy transfer function is inactive, the arrow is for example represented by a broken line, in particular of gray color.
    In addition, two or three alphanumeric indicators are arranged opposite each arrow, the color of these indicators being indicative of the activation state and / or the mode of the function. In particular, a first indicator, for example "OFF", is associated with an inactive activation state, in manual mode, a second indicator, for example "ON", is associated with an active activation state, in manual mode, and a third flag, for example "AUTO", is associated with an automatic mode, whether the activation state is active or inactive.
    When the function is inactive in manual mode, the first alphanumeric indicator is displayed in green, the second and third indicators being displayed in gray. When the function is active in manual mode, the second alphanumeric indicator is displayed in green, with the first and third indicators being displayed in gray. When the function is in automatic mode, whether the activation state is active or inactive, the third alphanumeric indicator is displayed in green, the first and second indicators being displayed in gray.
    The third attribute, indicative of the operating state of the function, comprises for example a specific color of the object associated with the function, for example, in the case of a transfer function, a specific color of the function. the representative arrow of this energy transfer, for example an orange color when the function is degraded.
    The third attribute preferably also comprises a specific type of display of the alphanumeric indicator representative of the activation state and / or the mode of the function.
    For example, a normal operating state is indicated by green or gray alphanumeric indicators depending on the current activation status and mode. A degraded state of operation is indicated by an orange box surrounding the alphanumeric indicators, the color of these indicators being green or gray depending on the current activation state and the mode of the function. A lost operating state is indicated by a line blocking the indicator associated with the current activation state and the current mode of the function. In this lost operating state, the function is not controllable.
    In addition, when a function is not controllable, a specific color of the alphanumeric indicator associated with the activation status or the selected mode can indicate whether the activation state and the current mode of the function comply with the activation state and the selected mode.
    Preferably, the display module 30 is also configured to control the display on the window, for at least some of the functions, in particular for at least one energy transfer function, of at least one operable control object. by an operator, by means of the touch screen 14, to change the activation state and / or the mode of this function.
    For example, the actuation of this object by an operator is intended to control an activation or deactivation in the manual mode of the function, or a selection of the automatic mode for the function.
    Preferably, the display module 30 is configured to display this control object in a specific representation, for example highlighted, when a modification of the activation state of the function is recommended, in order to incite the control unit. operator to change the activation state of the function. Following such an operator control action, and following a change in the activation state and / or mode of a function by the control and monitoring system 2 in response to this actuation , the display module 30 is adapted to update on the screen 14 the type of display of the object representative of this function.
    In particular, the display module 30 is able to update the first attribute of this object, indicative of the current activation state of the function and / or its second attribute, indicative of the mode of the function.
    Such an update allows the operator to become aware of the consideration of its control action, and the actual modification of the activation state and / or the mode of the function.
    As described in more detail below, following an action to change the activation state of a function, the control and monitoring module 44 is able to control the activation state of the equipment. performing this function so that the activation state of the function is that selected by the operator.
    Preferably, as a result of such a modification action, the display module 30 is configured to display on the window dedicated to the system associated with the function, for each of the equipment performing this function, an object representative of the state activation and operation of this equipment.
    These objects are preferably displayed temporarily, i.e. for a predetermined duration, so as not to overload the display window because they correspond to logical and non-functional elements.
    Such a display allows the operator to become aware of the changes in the activation logic states made in order to modify the activation state of the function, and thus to improve his awareness of the situation.
    Such a display also allows the operator to understand the operation of the system, so as to be able to manually control each of the equipment of the system in case of failure.
    Moreover, when a function is in a degraded, back-up or lost operating state as a result of a failure of a device associated with this function, the display module 30 is adapted to signal this failure, for example by displaying an object representative of the degraded operating state of this equipment.
    Preferably, when such a failure occurs, the display module 30 displays an object representative of the operating state of each equipment associated with the function in a degraded operating state as a result of this failure.
    Such a display enables an operator to become aware of the equipment (s) in question when a function is in a degraded, back-up or lost operating state, while minimizing the workload necessary for the operator.
    The display module 30 is thus able to control the display on the screen 14, at every instant, of information relating to: - the current activation state, active or inactive, the functions implemented by a system, - in manual or automatic mode, of these functions, - in the operating, normal, degraded or lost state of these functions, - in the activation and operation states of the equipment of the system, at least when these equipment are in degraded or lost operating state or participate, with another equipment in degraded or lost operating state, to the implementation of a function, - the controllable or uncontrollable nature of these functions.
    Preferably, the display module 30 is also configured to display a logical block diagram of a system in addition to the functional block diagram.
    On such a logical block diagram, each piece of equipment is represented by a specific object, and the different objects are connected together as are the equipment in the system. The display of such a logical block diagram makes it possible, for example, for an operator, following an incident, to analyze the incident a posteriori. Indeed, the progress of a procedure following a failure should involve only the functional synoptic.
    Such a logic block is for example displayed in response to a command from an operator on a dedicated command icon, or automatically, for example in case of failure.
    This logical block diagram can be displayed in addition to or in replacement of the functional block diagram of the system. The configuration application 40, hereinafter called configuration module 40, is able to detect an action of selection of a state of activation of the function by an operator via the human machine interface 16.
    This selection action comprises, for example, actuation of the actuatable object associated with the function by an operator, by means of the man-machine interface 16, in particular by means of the touch screen 14.
    Preferably, the configuration module 40 is also configured to detect an action of selection of a mode of the function by an operator via the human machine interface 16.
    In addition, the configuration module 40 is also configured to detect an action to select an activation state of a device. The system control and monitoring application 44 of the system, hereafter called control and monitoring module 44, is configured to check in real time the activation state (on / off) of each of the equipment of the system. and the operating status (normal, degraded, etc.) of these devices.
    The control and monitoring module 44 is also configured to derive, from the activation and operation states of the equipment of the system, the activation status and the operating state of the functions implemented by this system.
    In particular, if a failure occurs on a device, the control and monitoring module 44 is able to detect this failure and to deduce which functions of the system are affected by this failure, including which functions are in degraded operating state, rescue or lost.
    The control and monitoring module 44 is configured to transmit this information to the display module 30, in particular the activation state, the mode, the operating state and the controllable or uncontrollable nature of each of the functions, for display by the display module 30, on the screen 14, of this information.
    Furthermore, the control and monitoring module 44 is configured to control the activation states of the various equipment of a system, according to an activation state of one or more functions implemented by this system selected by an operator and detected by the configuration module 40.
    In particular, the control and monitoring module 44 is configured to determine, from a selected activation state of a function, as detected by the configuration module 40, the logic activation state of each device. of the system for achieving this activation functional state.
    In particular, the control and monitoring module 44 is configured to determine, from the selected activation functional state and the current operating logic state of the equipment of the system associated with the function, a series of operations. to implement to switch the activation state of the function from its current activation functional state to the selected activation functional state.
    This series of operations includes, for example, commands for modifying the logic states for activating at least two devices of the system, followed by a verification of the application of these commands. This series of operations is determined by the control and monitoring module 44 in accordance with a procedure associated with the function, stored in the memory 20.
    Furthermore, the control and monitoring module 44 is configured to implement this series of operations, by sending successively to the equipment associated with the function a control signal, in order to switch these devices into the logical state of activation adapted to the selected activation functional state.
    In addition, the control and monitoring module 44 is able to verify, after sending each command to a device, that this command has been received and taken into account by the equipment. In some cases, an activation state or a mode selected by an operator for a first function is incompatible with the activation state or the current mode of a second function. Such an incompatibility can for example occur when two functions are exclusive activation, that is to say when the activation of a function requires the deactivation of another function.
    In such a case, the control and monitoring module 44 is able to detect such an incompatibility, and to modify the activation state and / or the mode of the second function accordingly by informing the operator of such a device. derivative effect. After a modification of the activation state and / or the mode of a function, the control and monitoring module 44 is configured to check the activation state and the current mode of this function. , and for transmitting to the display module 30 the activation state and the current mode of the function, with a view to modifying the first attribute and / or the second of this function on the screen 14.
    On the other hand, when the automatic mode is selected for a function, the control and monitoring module 44 is able to automatically select the activation state of this function, in accordance with predefined procedures.
    In addition, when the manual mode is selected for a function, the control and monitoring module 44 is configured to determine, based on the current state of the system and these procedures, a command to change the state of the system. activation of this function to be performed by the operator, and to control the display by the display module 30 of the control object associated with this command in a specific representation, for example highlighted, in order to prompt the operator to change the activation state of the function. The command determined by the control and monitoring module 44 is for example a command that would be selected by the control and monitoring module 44 if the function was in automatic mode.
    FIG. 2 illustrates, by way of example, a functional block diagram able to be represented by the display module 30 on a window 50 of the screen 14.
    The functional block diagram shown in FIG. 2 relates to a fuel management system.
    This system is capable of implementing several distinct functions, in particular energy storage or transformation functions, and energy transfer functions. To this end, the system includes several equipment, including first and second sets of fuel tanks, each set of tanks being associated with a fuel storage function.
    The system further comprises first and second engines, each adapted to be fueled by at least one of the sets of tanks and to transform the energy provided by this or these sets of tanks into mechanical energy.
    The system also comprises several pumps, suitable for transferring fuel from a given set of tanks to the other set of tanks or to a motor or several engines of the aircraft.
    For example, the system includes a first set of pumps configured to transfer fuel from the first set of tanks to a first engine of the aircraft and / or to the second set of tanks, and a second set of pumps configured to transfer fuel to the first set of tanks. fuel from the second set of tanks to a second engine and / or to the first set of tanks.
    Each set of pumps comprises for example a first pump and a second pump, which can be operated together or separately.
    As illustrated in FIG. 2, each function that can be performed by the system is represented on the functional block diagram by an object representative of this function and the current activation state of this function.
    The functional block diagram illustrated in FIG. 2 furthermore comprises a button 90 operable between a first position corresponding to an automatic mode in which all the functions that can be in an automatic mode are in this mode, with an activation state of the functions that do not can be changed manually, and a manual mode in which the activation status of the functions can be changed by an operator. In Figure 2, the manual mode is selected.
    In particular, the fuel transfer functions between the equipment of the system are distinguished from the functions of use or storage of fuel.
    In particular, the fuel storage function performed by the first set of tanks, respectively by the second set of tanks, is represented by an object 100, respectively 102, which is for example of polygonal shape. This object is partially colored, the colored proportion of the object being representative of the filling level of the set of tanks.
    Also shown on the functional block diagram is an indicator 103 of the balance of the mass of fuel between the two sets of tanks.
    This indicator 103, in the form of a spirit level, allows an operator to visualize a possible imbalance of the mass of fuel, and to control accordingly a transfer of fuel between the sets of tanks of the aircraft. This indicator displays a fuel mass balancing function. A more comprehensive center of gravity management function could also involve the mass and position of passengers, baggage, etc.
    Moreover, the energy transformation functions performed by the motors are each represented by an object 104, 106.
    Each energy transfer function, which in this example is a fuel transfer function, is represented by an arrow oriented in a predetermined direction. This arrow connects two objects representing another function or equipment, the direction of the arrow being representative of the direction of the transfer of energy.
    In the example illustrated in Figure 2, six distinct energy transfer functions are represented as six arrows.
    A first arrow 108 connects the object 100 representative of the fuel storage function of the first set of tanks to the object 104 representative of the energy transformation function by the first engine. The first arrow 108 is oriented towards the object 104.
    Similarly, a second arrow 110 connects the object 102 representative of the fuel storage function of the second set of tanks to the object 106 representative of the energy transformation function by the second engine. The second arrow 110 is oriented towards the object 106.
    The first arrow 108 and the second arrow 110 symbolize the fuel transfer function of the first set of tanks to the first engine and the fuel transfer function of the second set of tanks to the second engine respectively.
    A third arrow 112 and a fourth arrow 114 connect the first arrow 108 to the second arrow 110, the third arrow 112 facing the second arrow 110 and the fourth arrow 114 facing the first arrow 108.
    The third arrow 112 and the fourth arrow 114 symbolize the fuel transfer function of the first set of tanks to the second engine and the fuel transfer function of the second set of tanks to the first engine respectively.
    A fifth arrow 116 and a sixth arrow 118 interconnect the two objects 100, 102 representative of the fuel storage function of the first and second sets of tanks, the fifth arrow 116 being directed towards the object 102 and the sixth arrow 118 being oriented towards the object 100.
    The fifth arrow 116 and the sixth arrow 118 symbolize the fuel transfer function of the first set of tanks to the second set of tanks and the fuel transfer function of the second set of tanks to the first set of tanks respectively.
    The various objects representative of the functions performed by the system as illustrated in FIG. 2 have at least one attribute indicative of the current active or inactive activation state, of the associated function, and of the current operating state. , normal or degraded, etc. of this function.
    Preferably, each of the arrows 108, 110, 112, 114, 116 and 118, representative of a power transfer function, has at least a first attribute, indicative of the current activation state of the function, at the minus a second attribute, indicative of the mode of the function, at least one third attribute, indicative of the operating state of the function, and at least one fourth attribute indicative of the controllable or uncontrollable nature of the function.
    The first attribute is for example a color of the arrow and / or a type of drawing of the arrow, and / or an alphanumeric indication displayed next to the arrow and whose content and / or display mode depends on the current activation state of the function.
    For example, the arrow is represented by a dashed but uninterrupted line, in particular of green color, when the function is active. According to this example, when the energy transfer function is inactive, the arrow is for example represented by a broken line, in particular of gray color.
    In the example shown in Figure 2, the arrows 108 and 110 are represented by a dotted line, which means that the transfer of fuel from the first set of tanks to the first engine is active, and that the transfer of fuel from the second set of tanks to the second engine is also active.
    In contrast, the arrows 112, 114, 116 and 118 are represented by a broken line, which means that no fuel transfer between the first and second sets of tanks, between the first set of tanks and the second engine, or between the second set of tanks and the first engine, takes place.
    Furthermore, each arrow 108, 110, 112, 114, 116 and 118 is provided with a symbol 120 of connector type, placed along the arrow. Each symbol 120 comprising a first portion 120a, in the form of a male connector, for example in the form of a square, and a second portion 120b, in the form of a female connector, for example in the form of a hook.
    The relative position of the first 120a and second 120b portions of a connector 120 is indicative of the activation state of the associated function.
    In particular, when the function is active, the first 120a and second 120b parts of the connector are nested, as shown on the arrows 108 and 110. When the function is inactive, the first 120a and second 120b parts of the connector 120 are away one of the other, in particular facing each other on the broken line of the arrow, as shown on the arrows 112, 114, 116 and 118.
    Preferably, the color of a connector 120 is also indicative of the activation state of the associated function and / or the controllable or uncontrollable character of this function. Thus, the fourth attribute, indicative of the controllable or uncontrollable character of a function, is for example formed by a specific color of the connector 120.
    For example, when the function is controllable and active, the connector 120 is green, and when the function is controllable and inactive, the connector 120 is gray in color. When the function is uncontrollable, whether active or inactive, the connector 120 is for example orange.
    In addition, each arrow 108, 110, 112, 114, 116 and 118 is associated with at least one alphanumeric indicator, indicative of the activation state of the function and the mode of this function.
    For example, as illustrated in FIG. 2, two or three alphanumeric indicators are arranged opposite each arrow 108, 110, 112, 114, 116 and 118. A first indicator 124, for example "OFF", is intended to signal a inactive state of the function in manual mode, a second indicator 126, for example "AUTO", is intended to signal an automatic mode of the function, regardless of its activation state, and a third indicator 128, for example "ON" is intended to signal an active state of the function in manual mode. The first, second and third indicators are successively arranged from upstream to downstream of the arrow.
    Preferably, the three indicators 124, 126 and 128 are displayed simultaneously when the automatic mode is selected, and this mode is indicated by displaying the indicator 126 representative of the automatic mode of the function in a predetermined color, for example in green the other indicators 124, 128 being displayed in another predetermined color, for example in gray.
    On the other hand, when one of the active or inactive states is selected in manual mode, only the two indicators 124 and 128 can be displayed, the current activation state of the function being indicated by displaying the indicator 124 or 128 representative of this activation state in a predetermined color, for example in green, the other indicator 128 or 124 being displayed in another predetermined color.
    Thus, in the diagram of FIG. 2, the functions represented by arrows 108, 110, 116 and 118 are in automatic mode, while the functions represented by arrows 112 and 114 are in manual mode, and in a state of inactive activation.
    Furthermore, each arrow 108, 110, 112, 114, 116 and 118 comprises an object 132 for controlling the current activation state of the associated function via the mode of this function. This object 132 is movable by an operator along the associated arrow between a position of inactivation of the function in manual mode, a position to switch to automatic mode of activation / inactivation, and a position of activation of the function. manual mode.
    In the inactivation position in manual mode, the object 132 is positioned opposite the indicator 124 for signaling an inactive activation state of the function.
    In the activation position in manual mode, the object 132 is positioned opposite the indicator 128 for signaling an active activation state of the function.
    In the position of passage in automatic mode, the object 132 is positioned opposite the indicator 126 intended to signal an automatic management of the activation state of the function. The control object 132 comprises, for example, a square shape surrounding the first portion 120a of the connector 120 associated with the function, as illustrated in FIG. 2. The control object 132 can be moved between the three positions by an operator using the of the man-machine interface 16, in particular by moving a control member on the touch screen 14 from the area of this screen displaying the control object 132 to the target position for this control object.
    Such a displacement of the control object 132 allows an operator to select a selected activation state of the associated function via one of its available modes.
    The third attribute is for example a specific color of the arrow and / or an alphanumeric indication displayed next to the arrow and whose content is displayed only when the operating state of the function is degraded, backed up or lost. In particular, in a normal operating situation, the color of the arrow is that associated with the normal operating state of the function, that is to say green or gray according to its activation state, and in a state of degraded operation, emergency or lost, the arrow is orange.
    Moreover, the window 50 displays a command icon 150 that can be operated by an operator, and whose operation makes it possible to display, as a replacement or addition to the functional block diagram, a logical block diagram of the equipment of the system.
    The window 50 also displays command icons 152 that can be actuated by an operator, and whose operation makes it possible to display an object representative of the logical states of activation and operation of certain equipment of the system, for example associated with a particular function. .
    An exemplary implementation of a device control method of a system of an aircraft using the control and monitoring system 2 will now be described with reference to Figure 3, which is a diagram of the implementation of this method, and Figures 2 and 4, which illustrate a window displayed on the screen 14 for the pilot during the implementation of this method.
    This example is described in connection with the control of the fuel storage system described with reference to FIG.
    In the exemplary implementation of the described method, consider an initial state 200 of the system which is that shown in Figure 2.
    In this initial state, the display module 30 controls the display, on a window of the screen 14, of a functional block diagram representative of the activation state of the functions implemented by the system, such as shown in Figure 2.
    In this initial state 200, only the fuel transfer functions of the first and second set of tanks to the first and second engines respectively, represented by the arrows 108 and 110, are active.
    The fuel transfer functions between the two sets of tanks, represented by the arrows 116 and 118, are in the automatic mode with an inactive activation state.
    The fuel transfer functions between the first set of tanks and the second engine and between the second set of tanks and the first engine, represented by the arrows 112 and 114 respectively, are in the manual mode with an inactive activation state.
    In a step 202, an operator selects, via the human machine interface 16, an activation state of one of the functions of the system, with a view to modifying this activation state. For this purpose, the operator moves the control object 132 from the activation state of this function from its current position to the selected position.
    For example, if, despite the automatic management of the fuel balance, an imbalance of the masses of fuel between the first and second sets of tanks is found, an operator activates in manual mode the fuel transfer function from the first set of tanks to the second set of tanks, by moving the control object 132 associated with the arrow 116 from its current position, ie opposite the indicator 126 of the automatic mode, to a position opposite the indicator 128 of the active activation state.
    In this example, the modification of the selected activation state also corresponds to a modification of the mode of the function, from the automatic mode to the manual mode.
    In a step 204, the configuration module 40 detects this selection action of the activation state.
    In the described example of activation of the fuel transfer function from the first set of tanks to the second set of tanks, the configuration module 40 detects the change of the activation state from the inactive state to the first set of tanks. active state, and the change from the automatic mode to the manual mode associated with it.
    Then, during a step 206, the control and monitoring module 44 determines, from the activation functional state selected for the transfer function, a logic activation state of each of the system equipment associated with the transfer function. this function, so that when each of these devices is in the activation logic state determined by the control module, the function is in the selected activation functional state.
    In particular, during step 206, the control and monitoring module 44 determines, from the selected activation functional state and the current operating logic state of the equipment of the system associated with the function, a series of operations to be implemented in order to switch the activation state of the function from its current activation state to the selected activation state.
    This series of operations is determined by the control and monitoring module 44 in accordance with a procedure associated with the function, stored in the memory 20.
    In step 206, the control and monitoring module 44 checks whether the activation state selected for the function is compatible with the current activation state and / or with the current mode of the other functions implemented. by the system.
    If an incompatibility between the activation state selected for the function and the current activation state and / or with the current mode of a second function is detected, the control and monitoring module 44 detects this incompatibility.
    The control and monitoring module 44 modifies the activation state and / or the mode of the second function accordingly, and informs the display module 30 of this modified activation state and / or modified mode.
    In response, the display module 30 moves the control object 132 associated with this second function from its current position to a position opposite the indicator 124, 126 or 128 corresponding to the modified activation state and / or the modified mode.
    For example, to activate the fuel transfer function from the first set of tanks to the second set of tanks, the control and monitoring module 44 determines the logical operating state of each of the pumps of the first set of pumps allowing for the effective activation of this transfer function.
    In addition, the control and monitoring module 44 detects that the active activation state of the fuel transfer function from the first set of tanks to the second set of tanks necessarily implies an inactive activation state of the function. transferring fuel from the second set of tanks to the first set of tanks.
    As a result, the control and monitoring module 44 selects the manual mode of this fuel transfer function while keeping the inactive activation state of this fuel transfer function.
    In addition, the control and monitoring module 44 informs the display module 30 of this modified mode.
    In response, the display module 30 moves the control object 132 associated with this second function from its current position, ie opposite the indicator 126, to a position opposite the indicator 124 corresponding to a state of Inactive activation of the function in manual mode, as shown in Figure 4.
    In a step 208, the control and monitoring module 44 implements the series of operations determined during step 206, by sending, to each of the equipment, or at least to the equipment that is not in operation. determined logic activation state, a logic control signal for switching these devices into the determined activation logic state.
    In step 208, the control and monitoring module 44 checks, after sending each control signal to a device, that this command has been received and taken into account by the equipment, that is to say that is, the logic activation state of this equipment has been switched to the determined activation logic state.
    In addition, the control and monitoring module 44 informs in real time the display module 30 of the logic activation state of the equipment associated with the function. Preferably, the display module 30 then displays, for each of these devices, an object representative of the logic activation state of this equipment.
    In particular, to activate the fuel transfer function from the first set of tanks to the second set of tanks, the control and monitoring module 44 sends a control signal to the pumps of the first set of pumps, or at least the pumps of this set which are not in the logic activation state determined in step 206, in order to switch these pumps in the determined activation logic state.
    The control and monitoring module 44 verifies, after sending each control signal to a pump, that the logic activation state of this pump has been switched to the determined activation logic state.
    During a step 210, the logic activation state of the pumps of the first set of pumps is then displayed on the functional block diagram by the display module, as illustrated in FIG. 4.
    In particular, two sets of icons 220, 222 representative of two pumps of the first set of pumps are displayed on the functional block diagram of FIG. The color of these icons is representative of the logic activation state of these pumps.
    Then, during a step 210, the control and monitoring module 44 checks the activation state of the function.
    If this activation functional state conforms to the selected activation functional state, the control and monitoring module 44 transmits this information to the display module 30. The display module 30 then modifies the first attribute, indicative of the activation state of the function, on the functional block diagram.
    In particular, as illustrated in FIG. 4, the display module 30 represents the arrow 116 in the form of an unbroken discontinuous line, displays in gray the indicator 124 associated with the manual mode and the inactive activation state. , and displays in green the indicator 128 associated with the active activation state in manual mode of the fuel transfer function from the first set of tanks to the second set of tanks.
    The system and the control method described thus allow an operator to directly control the functions implemented by a system, without having to individually control each equipment involved in the implementation of these functions.
    Moreover, the automatic determination by the control system of the logic activation states of the equipment of a system adapted to a selected activation functional state of a function facilitates the work of the crew. In particular, this automatic determination makes it possible to avoid systematic consultation of the procedure to be implemented for the desired activation functional state change, and also makes it possible to minimize the training time required to take control of the system. by an operator. Without necessarily avoiding the systematic consultation of the procedure, the latter is lightened which effectively reduces the training time. This automatic determination of the logic commands also makes it possible to minimize the risk of error.
    In addition, the control of a function can be performed by an operator by referring only to the screen of the display device, which facilitates the work of the operator. The display on the display device of a functional block diagram representative of a system, and the activation state of each of the functions implemented by this system also allows an operator to have a global awareness. the situation, in particular the link between the logical state of activation of the different equipment of the system and the functional state of activation of the associated functions. In addition, in the event of equipment failure, this functional block diagram provides the operator with a precise indication of the functions that are affected by this failure, as well as the impact of this failure on these functions.
    It should be understood that the embodiments described above are not limiting.
    In particular, although the invention has been illustrated with reference to a fuel management system, the invention can be applied to the control and monitoring of other types of aircraft systems, including management systems. energy, for example an electrical system, a fuel storage system, a propulsion system.
    In addition, according to one variant, the man-machine interface comprises, in replacement or in addition to the tactile control device, one or more control members, for example a mouse or a joystick, and / or a keyboard ...
    In the exemplary embodiment of the invention, the display module 30, the configuration module 40 and the control and monitoring module 44 are made in the form of software stored in the memory 20 and able to be executed by the user. processor 18, associated with the memory 20. In a variant, the display module 30, the configuration module 40 and the control and monitoring module 44 are made at least partially in the form of programmable logic components, or in the form of dedicated integrated circuits, included in the control and monitoring system 2.
