Definitions
- the description relates to resource management in an aircraft, in particular a military aircraft such as a combat aircraft.
- the description relates to a resource allocation device and an aircraft with such a resource allocation device.
- military aircraft in particular combat aircraft, can be viewed as a system network of sensors, effectors and control devices. Fighter planes often operate in a group consisting of two or more aircraft.
- a combat aircraft is typically designed in such a way that it can also act as a self-sufficient system.
- the concept of the self-sufficient system is understood to mean that the devices located in a combat aircraft communicate and interact with one another in order to be able to perform a task. This does not preclude the combat aircraft from communicating with external facilities such as a command post or another combat aircraft.
- a resource allocation device for an aircraft has an operator interface and a control unit.
- the operator interface is designed to receive user input and to generate control commands based on this.
- the control unit is designed to activate one of a plurality of possible use cases for resource allocation to processes based on the control commands.
- the control unit is further designed to execute one or more processes and, when executing the processes, to access a peripheral device or more peripheral devices of the aircraft, an application case defining which process receives which share of a total of available resources of the aircraft.
- a use case is a mission schedule, which defines the key data and the operation of the processes during a certain mission or a phase of an operation.
- a use case can also be referred to as a resource allocation plan. The way of working is valid as long as the selected application is active. Different use cases can be selected or activated for different missions or phases of an operation. Thus, a use case defines which process receives how many resources and which resources while the said use case is selected or active. This makes it possible to make a preselection before using the aircraft as to which processes are to be carried out with which resources and under which conditions.
- a process can also be referred to as a task or process and accesses peripheral devices and their functions in order to receive data and, based on this data, and possibly after a processing step, to deliver a result or intermediate result.
- Processes in a fighter aircraft often access sensors that record the environment. Under different mission or combat scenarios or deployment or flight phases, different sensor modes of operation are advantageous or different sensors are operated in different ways and with different intensities (and thus with varying energy requirements). This way of working can be part of a previously defined use case. The use of such use cases can relieve the pilot, because for certain scenarios only the corresponding use case has to be selected without the pilot having to worry about the selection of sensors and the allocation of resources to individual processes.
- a use case is loaded into the control unit and this use case defines how the resources are allocated to a process.
- the processes access peripheral devices when they are running.
- the approach described here for resource allocation makes it possible to dynamically adapt the available resources during an operation or mission of the aircraft as a function of the external conditions.
- the framework conditions for the use of the resources can be dynamically adapted by the corresponding processes during the operating time of the aircraft.
- the processes running on a flight computer can be dynamically assigned a different share of the resources. This means that it is not necessary to assign resources to the peripheral devices manually and individually. Rather, this is done in a bundled manner by selecting a suitable use case, with one use case advantageously allocating the resources of several peripheral devices to several processes.
- the user interface can be designed as a human-machine interface in an aircraft, e.g. as a display together with input elements (e.g. buttons or switches or other known input elements suitable for a combat aircraft) in a cockpit of the aircraft.
- input elements e.g. buttons or switches or other known input elements suitable for a combat aircraft
- An operator can make inputs via the user interface and information can be displayed to this operator.
- the resource allocation device can have a configuration interface which is designed so that use cases are loaded into the control unit before the start of a mission of the aircraft.
- the use cases can, for example, be loaded as files into a memory of the control unit and held there for retrieval by the operator during the operating time of the aircraft.
- the priorities or the relevant information change.
- it is highly relevant to monitor the area in front of the aircraft in order to avoid collisions.
- the tracking of a movement path of an object may be of higher relevance because this information is decisive in order to accomplish the mission.
- the control unit makes it possible that, depending on the flight phase or the mission, a process receives the resources specified in advance according to an application in order to process the data relevant in the respective flight or mission phase with the required precision and in the required time and the corresponding Deliver results.
- the resource allocation device as described herein enables a dynamically changeable implementation of the operational concerns and / or requirements for an aircraft as well as a variable allocation of resources to the processes carried out by the control unit depending on a respective situation.
- a peripheral device is an element from the group comprising the following elements: an infrared sensor, an optical camera, a radar system, a laser sensor, an active or passive sensor for electronic warfare, a communication system.
- the resource allocation device as described herein in particular allocates the authorization to a process to use one of these peripheral devices with a certain priority and for a certain time.
- the available resource of a peripheral device is the usage time of a peripheral device by a process.
- a process is an operation from the following list of operations: searching for an object, observing an object of interest, identifying an object, controlling a guided missile released by one's own aircraft, tracking an object,
- control unit is designed to dynamically and selectively access one or more of the peripheral devices when executing a process based on a current utilization of the peripheral devices.
- peripheral devices For the process of observing an object, for example, the infrared sensor, the optical camera, or the radar system or a Combination of these can be chosen.
- the control unit can select one or more of the peripheral devices in question for the process. This approach enables the peripheral devices to be dynamically assigned to the processes so that the resources in the aircraft are used better overall and a single bottleneck (for example in the form of a single, heavily used peripheral device) does not block or slow down the execution of several processes.
- control unit is designed to contain a plurality of use cases, each use case differing from the other use cases in that each use case assigns different proportions of the totality of available resources to the processes.
- control unit is designed to activate a specific use case from the plurality of use cases based on the control commands during the operating time of the aircraft.
- control unit is designed to assign a priority to the processes, the control unit also being designed to service the processes with resources according to their priority if the total of available resources is not sufficient for all processes with the resources assigned to them according to plan to use.
- control unit is designed to automatically allocate more resources to a process when a condition defined in the use case occurs.
- This embodiment comes into play when the sensors of the aircraft detect an enemy object or a weapon aimed at the aircraft or a missile on approach. In this case, i.e. when this condition occurs, the process that is tracking the enemy object or the approaching missile is allocated more resources without the need for the pilot to intervene.
- aircraft with a resource allocation device as described herein is indicated.
- the aircraft is a military aircraft, such as a combat aircraft.
- the resource allocation device can, however, also be used in other vehicles in which the resource allocation of devices to processes plays a relevant role, in particular in the military sector.
- the resource allocation device can be used in combat ships or military land vehicles.

- the configuration interface can be designed, for example, as a wired or wireless data transmission interface to which an external computer can be connected in order to transmit the data of one or more applications to the control unit 40.
- the system status database 42 and the object tracking database 44 are designed as volatile or non-volatile memory modules.
- the memory modules can be part of the control unit 40 or exist separately therefrom. If the memory modules are separated from the control unit 40, then there is at least one data connection between the control unit 40 and the memory modules which data can be exchanged in at least one direction (reading, from the memory modules to the control unit), but preferably bidirectionally.
- the sensor management 50 is implemented as a function in the control unit 50 and is executed by it.
- the sensor management 50 for its part contains further functions such as the control specification unit 52 and the request generation unit 54.
- the control specification unit 52 contains at least the active use case, which specifies the resource allocation to processes.
- the control specification unit 52 can contain several other predefined applications. However, only one use case is preferably active at a time. It is also conceivable that the control input unit 52 activates its own application case for different system areas, but in such a case each application case can exclusively have one or more processes and one or more resources / peripheral devices so that the assignments of several applications do not collide or create a conflict.
- the active application is selected via the operator interface 20.
- the control specification unit 52 receives information from the system status database 42 and the object tracking database 44.
- the system status database 42 contains information about the aircraft in which the resource allocation device 10 is arranged. This information contains the status information about the aircraft as such and about the individual systems of the aircraft, such as the operating status, the load, the measured values reported by sensors, etc., and also information about the surroundings of the aircraft.
- the object tracking database 44 contains information about objects which are external to the aircraft and which can generally be referred to as objects defining the situation or the scenario.
- objects defining the situation or the scenario.
- information on the objects, their movement and other parameters are held.
- control unit 40 executes processes (tasks) which access peripheral devices 60, such as, for example, sensors of the type described above, receive data from the peripheral devices, and process or forward this data in order to contribute to the fulfillment of a mission afford to.
- the control unit 40 thus carries out computer-implemented processes which have at least read access to the peripheral devices and which further process the data thus obtained.
- the use case activated in the control specification unit 52 indicates, based on the specifications of the use case and possibly with the addition of the information from the system status database 42 and the object tracking database 44, the processes which the control unit 40 executes and which access the peripheral devices 60 (e.g. sensors) , Resources too.
- the control specification unit 52 defines, based on the active application, which process of the control unit 40 is allowed to access which sensor 60 for how long and with which performance level. This allocation of resources takes place in consideration of the specifications in the application.
- the operator interface 20 also supplies control commands to the request generation unit 54, which is responsible for the direct control of the peripheral devices 60 based on the specifications of the control input unit 52.
- the request generation unit 54 can be connected to each peripheral device 60 so that control commands can be transmitted to the peripheral devices 60.
- the request generation unit 54 accesses information in the object tracking database 44 in order, for example, to adjust the sensors appropriately so that an object to be tracked is appropriately detected by a sensor or a group of sensors.
- the peripheral devices 60 supply their output values both to the operating interface 20, where they are displayed to the pilot, and to the Object tracking database 44 which stores updated information about an object.
- FIG. 2 shows a resource allocation device 10 which, compared to the example in FIG. 1, furthermore contains a request allocation unit 56.
- the request assignment unit 56 assigns a peripheral device 60 or a sensor to a request supplied by the request generation unit 54. A further functional separation has thus taken place here.
- a peripheral device 60 or a sensor assigns a peripheral device 60 or a sensor to a request supplied by the request generation unit 54.
- a further functional separation has thus taken place here.
- only a resource request is generated by the request generation unit 54, but the resource is not accessed directly.
- the access to the peripheral devices and the assignment of the peripheral devices to a process takes place in this example by the request assignment unit 56.
- the request assignment unit 56 has, in particular, the task of load distribution between the individual peripheral devices.
- the peripheral devices supply information about their assignment and their utilization to the request assignment unit 56, so that a better load distribution can take place here, comparable to a closed control loop.
- the resource allocation device 10 described here enables a functional separation between the request for a function by the pilot and the selection and allocation of a resource by the
- Resource allocation device 10 In an aircraft, the pilot only specifies which function is to be carried out using the resource allocation apparatus 10, and the application specifies how the function is carried out and which resources are used for it.
- the control input unit 52 is embedded as a functional block in a flight control computer and evaluates inputs from the pilot as well Sensor values about the situation of the aircraft, the surroundings and objects in the vicinity of the aircraft.
- the pilot can use the operating interface 20 to set the focus for the observation and the control input unit 52 determines, based on the application, which sensors are controlled and how in order to deliver the results desired by the pilot with the accuracy and / or depth of detail specified for the application .
- the pilot can, for example, prioritize a terrain area or an object, and the control specification unit controls the peripheral devices 60 accordingly and assigns corresponding resources to the processes carried out by the control unit 40.
- the control specification unit 52 prioritizes from a plurality of processes in order to meet the priorities specified by the pilot, taking into account the resource allocation specified in the application.
- the pilot does not access the processes directly in order to assign them a priority, but rather specifies which task the control specification unit 52 should primarily carry out and the control specification unit 52 assigns resources to the processes according to the active use case, thus those specified by the pilot Task is accomplished.
- more resources can be automatically assigned to a process if there is more information about the information processed by that process. If, for example, a process is tracking an object which turns out to be an object belonging to hostile forces, the control specification unit 52 can allocate more resources to this process in accordance with the previously defined and active use case. It is also conceivable that the pilot specifies the relevance of an object via the operating interface 20, then the process tracking this object also receives more resources, provided that the active application allows the pilot to classify an object.
- the peripheral devices 60 can be sensors, communication devices or other functional units of an aircraft.
- the control input unit 52 can, for example, be designed to access another aircraft of its own association via a communication connection and to receive measurement results from Query the sensors of the other aircraft for your own needs. This can be done, for example, when the other aircraft is in a better position to deliver better reconnaissance results or when the own aircraft does not have enough resources or these are fully utilized.
- the load distribution and the allocation of resources to processes of the control unit 40 can thus take place not only locally on an aircraft, but also distributed over several aircraft.
- FIG. 3 shows, by way of example, a combat aircraft 1 which contains a resource allocation device 10 as described with reference to FIGS. 1 and 2.
- resource allocation device 10 can also be used in other vehicles, in particular military combat vehicles.
- Resource allocation device 10 Resource allocation device 20 Operating interface 30 Configuration interface 40 Control unit 42 System status database 44 Object tracking database 50 Sensor management 52 Control specification unit 54 Request generation unit 56 Request allocation unit
