Air traffic control system for air traffic control and method for transmitting video and / or image data

Description

[0001] The invention relates to an air traffic control system for air traffic control. Furthermore, the invention relates to a method for transmitting video and / or image data in an air traffic control system.

[0002] Air traffic control systems (ATC systems) are used for air traffic control or airspace monitoring for both civil and military applications. These systems typically include several air traffic controller workstations, where air traffic controllers receive information about aircraft in the airspace, such as airplanes, helicopters, drones, and the like, in order to control and manage the airspace and the aircraft therein.

[0003] Typically, each air traffic controller workstation is equipped with a processing unit, i.e., a computer running an operating system, as shown, for example, in US Pat. No. 6,628,321 B1, EP 1 936 583 A1, and in "Whitepaper: Introduction to remote virtual tower." These processing units receive the image and / or video data necessary for air traffic control or surveillance.

[0004] In addition, EP 1 7991 364 A1 discloses an air traffic control system in which transmitter-side video compression units can be designed as FPGAs in order to compress image data streams before they are transmitted via a fiber optic cable.

[0005] It is known from the prior art that video and / or image data is transmitted as optical signals via fiber optic cables. However, the fiber optic cables used are complex to install and maintain.

[0006] Furthermore, it is considered a disadvantage of the state-of-the-art air traffic control systems that the air traffic controllers are limited in their operation and / or functionality due to the permanently installed processing units. This also results in high noise levels, as several air traffic controllers must work in one room at their assigned air traffic controller workstations.

[0007] The object of the invention is to provide a cost-effective and simply constructed air traffic control system, while at the same time increasing the functionality.

[0008] The object is achieved according to the invention by an air traffic control system for air traffic control according to claim 1.

[0009] The basic idea of ​​the invention is to transmit video and / or image data via an Ethernet connection between a machine configured to run an operating system and a device without an operating system, i.e. a device with a correspondingly simple design. This reduces the costs of the air traffic control system while simultaneously increasing its functionality. This is due, among other things, to the fact that an Ethernet connection is used to transmit the video and / or image data instead of fiber optic cables. The Ethernet connection can also be bidirectional. This means that control commands assigned to the control function can also be transmitted via the Ethernet connection, so that the machine can be controlled via the device without an operating system using the Ethernet connection.

[0010] The noise level can also be reduced. This is due, among other things, to the fact that individual air traffic controllers can be more easily distributed throughout the room or even move to another room, as they are no longer tied to their controller workstations.

[0011] The control function ensures that the machine provides the desired video and / or image data so that it is transmitted to at least one operating system-free device.

[0012] The operating system running on the machine can be a Linux-based operating system. However, other operating systems may also be planned.

[0013] The operating system-free device, which is connected to the machine via the Ethernet connection, can thus provide a type of remote access to the machine, since both the control and the response to the control, namely the transmitted video and / or image data, are carried out via the Ethernet connection.

[0014] The at least one machine and the operating system-free device are arranged or integrated into a common network, for example a local area network (LAN) or a wide area network (WAN).

[0015] In principle, however, the machine and the operating system-free device can be located in different rooms, as they can communicate with each other via the Ethernet connection. This makes it possible for the machine to be housed, for example, in a server room or similar.

[0016] The machine running the operating system can also be referred to as an OS device. The device without an operating system can also be referred to as a non-OS device.

[0017] The devices assigned to the machine, also known as downstream systems, can be radio devices, telephones, video cameras or other devices from which corresponding data is to be transmitted via the machine to the operating system-free device.

[0018] The data received, i.e. the data requested by the devices assigned to the aircraft, can then be output accordingly on the operating system-free device so that the air traffic controller can perceive it.

[0019] The machine forwards the received control commands to the devices assigned to it to request the corresponding data. In other words, the machine forwards the control commands to the appropriate device(s).

[0020] One aspect provides that the air traffic control system has at least one air traffic control center, in particular an air traffic controller workstation, with the operating system-free device being assigned to the air traffic control center. In this respect, the operating system-free device is provided near the air traffic controller, who thus has direct access to the operating system-free device. The air traffic controller workstation can be a virtual air traffic controller workstation.

[0021] Another aspect provides that the operating system-free device is configured to process different data contents assigned to different air traffic control centers, in particular to different air traffic controller workstations. In this respect, it is possible for the video and / or image data actually intended for two different air traffic control centers or air traffic controller workstations to be available on an operating system-free device.

[0022] The operating system-free device that receives the different data contents, for example, two different video streams, can forward them to different display devices assigned to the operating system-free device. The display devices can each be assigned to a specific air traffic control center or air traffic controller workstation.

[0023] It can also be provided that two different data contents are displayed on a single display device, for example, in two different areas of the display device. The display shown by the display device can thus be divided into at least two separate areas in which different data contents are displayed, for example, a lower area and an upper area of ​​the display device. This can also be referred to as a split screen. This enables an operator or air traffic controller to monitor two different areas via one display device.

[0024] In principle, the different data contents can originate from two machines that are connected to the operating system-free device via a corresponding Ethernet connection.

[0025] In addition, the operating system-free device can receive at least two data sets, for example, two video streams. In particular, the data sets have the same data content.

[0026] In principle, redundancy can be created if multiple data sets are transmitted to the device without an operating system, which are then forwarded accordingly by the device without an operating system. The first data set and the second data set can be referred to as the main data set and the redundant data set ("standby"), respectively. The second data set can provide the same information as the first data set, especially if the first data set is faulty or fails.

[0027] The machine is the source from which the operating system-free device receives the video and / or image data. In this respect, the machine itself provides the data content. Alternatively, the video and / or image data is provided by a separately implemented source accessed by the machine. In either case, the source of the video and / or image data is associated with the machine.

[0028] Because the intermediate system is cloud-based and / or server-based, multiple different operating system-free devices can easily access the same machine via the cloud-based intermediate system. The cloud-based intermediate system is also part of the network, for example, the local area network or the wide area network.

[0029] According to an embodiment not part of the claimed invention, the at least one machine is based on its own hardware; in particular, the at least one machine is designed as a standalone computing unit. This means that the machine is a computer running the corresponding operating system. The computer is connected to the operating system-free device directly via the Ethernet connection configured as a peer-to-peer connection or via the interposed intermediate system, which is signal-transmittingly connected to both the computer and the operating system-free device via a corresponding Ethernet connection.

[0030] According to the claimed invention, the at least one machine is a virtual machine. This means that the machine is provided via a server or a computer network. In other words, the virtual machine represents a software encapsulation of a computing unit within an executable hardware system. The virtual machine thus replicates the computer architecture of a real, existing hardware computing unit.

[0031] Furthermore, the at least one machine is provided in a hardware system, as part of a cloud, or as part of a data center, which is configured to simultaneously establish connections with multiple operating system-free devices. As already explained, multiple operating system-free devices can be provided in the air traffic control system, which simultaneously access the at least one machine or receive data from the at least one machine. In this respect, these are bidirectional communication connections, with connections originating from the machine and connections going to the machine. The machine is provided virtually in a cloud or on a server (data center), with which the operating system-free device communicates via the Ethernet connection.

[0032] According to the invention, the operating system-free device is assigned to a touch-sensitive module. The machine can be easily controlled via the touch-sensitive device or module, since an operator of the touch-sensitive device or module can easily interact with the touch-sensitive display device, i.e., the corresponding screen of the touch-sensitive device or module, to enter inputs. The corresponding inputs entered on the touch-sensitive device or module are processed by the operating system-free device and converted into control commands. The operating system-free device is configured to control the machine via the Ethernet connection using the control commands. For this purpose, the operating system-free device therefore has the corresponding control function.

[0033] According to the invention, the operating system-free device has a bidirectional data connection to the touch-sensitive module. The control commands are entered via the touch-sensitive module and transmitted to the operating system-free device via the bidirectional data connection. These commands are then transmitted from the operating system-free device to the machine via the Ethernet connection. Conversely, data transmitted from the machine is forwarded via the operating system-free device to the touch-sensitive module so that it can be displayed on the touch-sensitive module, which comprises the display device. The data forwarded from the machine to the touch-sensitive module may be data other than the requested video and / or image data, for example, information.

[0034] The video and / or image data, which are also transmitted from the machine to the operating system-free device via the Ethernet connection, can be forwarded from the operating system-free device to the display device, in particular the touch-sensitive module, via a separately designed image and / or video data connection.

[0035] For example, the operating system-free device comprises a field-programmable (logic) gate array (FPGA), as well as a data memory, particularly a DDR memory. In this respect, the operating system-free device is simple and cost-effective, as it only comprises the FPGA for receiving and forwarding the video and / or image data or the control commands. The received video and / or image data is at least temporarily buffered in the data memory.

[0036] Furthermore, the operating system-free device can be designed as part of a peripheral device, in particular as part of a radar screen or as part of an electronic flight progress strip system. The operating system-free device can also be designed as part of a media system. In this respect, it is possible for the operating system-free device to be implemented in a peripheral device of the air traffic control system that would otherwise be used anyway, so that no additional hardware is required. This makes it possible, in particular, to limit the required installation space.

[0037] In principle, the number of devices used can be reduced, especially the number of screens used. A single-screen solution is proposed, where the air traffic controller can see all the information on a single screen. In other words, all functions can be displayed on a single screen. This significantly reduces the number of devices, space requirements, and waste heat.

[0038] The requested video and / or image data is transmitted indirectly to the device without an operating system via an intermediate system. Therefore, a cloud-based solution is provided due to the intermediate system.

[0039] The display device can be integrated into the operating system-free device or designed separately from the operating system-free device. The display device is assigned to an air traffic control center, so that the requested video and / or image data is displayed at the air traffic control center, particularly where the air traffic control center is an air traffic controller workstation. This allows the operator or air traffic controller to receive the relevant information directly at their workstation. Due to the operating system-free device, the operator or air traffic controller has greater freedom in terms of working methods and functionality.

[0040] In principle, data for a graphical user interface (GUI) can be transmitted from the machine to the operating system-free device via the Ethernet connection.

[0041] Specifically, the data transmitted from the machine to the operating system-free device is transmitted using a protocol that includes a user-defined Ethertype field in the Ethernet frame. This protocol can be used to transfer video and / or image data between the machine running the operating system and the operating system-free device. It is particularly optimized for GUI (Graphic User Interface) data.

[0042] Additionally, other data types can be sent to the operating system-free device for individual use via the Ethernet connection.

[0043] The data storage may include an active area and an inactive area.

[0044] The active area may be provided to transmit the video and / or image data (to the display device).

[0045] The inactive area can be designed to implement changes transmitted over the Ethernet connection. In other words, the data stored in the inactive area is modified based on commands transmitted over the Ethernet connection.

[0046] Once all data has been changed due to the commands transmitted over the Ethernet connection, the active and inactive areas swap so that a revised display can appear on the display device.

[0047] It may be provided that the graphical user interface to be displayed is divided into areas, for example areas with 32x32 pixels or other types of areas.

[0048] Only the areas that have changed are transmitted to the device without an operating system, reducing the amount of data transmitted over the Ethernet connection. This also reduces the required bandwidth.

[0049] Furthermore, an area can be provided in the data memory in which error / warning messages are stored that could be displayed when the operating system-free device is booted up if an error occurs, for example if the Ethernet connection is faulty or not available.

[0050] With the custom and proprietary protocol and the OS-free device, it is therefore possible to display error / warning messages from the OS-free device or to customize the video output.

[0051] In principle, the machine can be controlled via the operating system-free device. For example, the operating system-free device can be used to set frequencies to be used for air traffic control, activate certain air traffic control features such as "cross-coupling," and set up conferences and / or ground-to-ground communication links.

[0052] The operating system-free device comprises, in particular, a microcontroller that is connected to the FPGA for signal transmission. The microcontroller is assigned to the interface of the operating system-free device to the display device, in particular to the touch-sensitive module.

[0053] For example, the microcontroller communicates with the display device or the touch-sensitive module via the data connection, for example the USB connection.

[0054] In this way, the microcontroller can detect an input (press and / or release on the display device or touch-sensitive module) and send it to the FPGA. The FPGA converts the information received from the microcontroller into a corresponding control command, which is transmitted to the machine via the Ethernet connection.

[0055] In addition, the operating system-free device can have several interfaces, for example an audio interface, whereby the data received via the interfaces can be processed in the FPGA of the operating system-free device.

[0056] The touch-sensitive module or device is essentially a touch-sensitive display module or display device, which displays the received image and / or video data. Further advantages and features of the invention will become apparent from the following description and the drawings, to which reference is made. In the drawings: Figure 1 a schematic view of an air traffic control system for air traffic control, Figure 2 a schematic view of an air traffic control system for air traffic control, and Figure 3 a schematic view of an air traffic control system according to the invention for air traffic control.

[0057] In Figure 1 an air traffic control system 10 for air traffic control is shown, which is not part of the claimed invention and which comprises a machine 12 running an operating system and an operating system-free device 14.

[0058] The operating system-free device 14 is connected to the machine 12 via an Ethernet connection 16 so that data can be exchanged between the operating system-free device 14 and the machine 12 via the Ethernet connection 16.

[0059] The Ethernet connection 16 ensures, in particular, that the machine 12 and the operating system-free device 14 are integrated into a common network 18, for example, a local area network (LAN) or a wide area network (WAN). However, the operating system-free device 14 can be located in a different room than the machine 12. For example, the operating system-free device 14 is assigned to an air traffic control center 20, i.e., an air traffic controller's workstation, whereas the machine 12 is located in a server room or the like.

[0060] Furthermore, the Ethernet connection 16 ensures that control commands can be transmitted to the machine 12 via the operating system-free device 14. For this purpose, the operating system-free device 14 includes a corresponding control function that ensures that the operating system-free device 14 is configured to control the machine 12 accordingly.

[0061] In general, the air traffic control system 10 ensures that the operating system-free device 14 receives, among other things, video and / or image data from a source 22 associated with the machine 12.

[0062] In the embodiment shown, the machine 12 itself provides the source 22.

[0063] Furthermore, in the embodiment shown, the machine 12 and the operating system-free device 14 are directly connected to each other via a so-called peer-to-peer connection, so that the corresponding data is exchanged directly. Furthermore, the control commands are transmitted directly from the operating system-free device 14 to the machine 12 via the peer-to-peer connection.

[0064] In addition, the air traffic control system 10 includes a display device 24 associated with the operating system-free device 14. The display device 24 can be used to display the transmitted video and / or image data that the operating system-free device 14 receives from the source 22 or the machine 12.

[0065] In the embodiment shown, the display device 24 is designed as a touch-sensitive module 26, via which an operator can make inputs that are converted into control commands by the operating system-free device 14 and then transmitted to the machine 12, i.e., via the Ethernet connection 16.

[0066] For this purpose, an input is transmitted to the operating system-free device 14 via a data connection 28 via the touch-sensitive module 26 or the display device 24, which is designed to be touch-sensitive. The data connection 28 can be a USB connection that exists between the display device 24 or the touch-sensitive module 26 and the operating system-free device 14. In particular, the data connection 28 is a bidirectional data connection, so that data is also transmitted from the operating system-free device 14 to the display device 24 or the touch-sensitive module 26.

[0067] The operating system-free device 14 converts the inputs received via the data connection 28 into the control commands and transmits the control commands via the Ethernet connection 16 to the machine 12, which then implements the corresponding commands.

[0068] Depending on the commands received, the machine 12 provides different video and / or image data via the Ethernet connection 16, which are thus transmitted to the operating system-free device 14.

[0069] The operating system-free device 14 is in turn configured to transmit the transmitted video and / or image data to the display device 24 or the touch-sensitive module 26 so that they can be displayed there.

[0070] For this purpose, the bidirectional data connection 28 or a separately designed image and / or video data connection 30 can be used, which only transmits data in one direction, namely from the operating system-free device 14 to the display device 24 or the touch-sensitive module 26.

[0071] Basically, the operating system-free device 14 comprises an FPGA 32, a data memory 34 and a microcontroller 35, which is connected to the FPGA 32 for signal transmission.

[0072] The microcontroller 35 is assigned to the interface of the operating system-free device 14 to the display device 24 or the touch-sensitive module 26, i.e., the data connection 28. In this respect, the microcontroller 35 receives the inputs made via the display device 24 or the touch-sensitive module 26, which are then transmitted from the microcontroller 35 to the FPGA 32.

[0073] The FPGA 32 is configured to process the information transmitted by the microcontroller 35 and convert it into control commands. The FPGA 32 then sends the control commands to the machine 12 via the Ethernet connection 16.

[0074] In addition, the FPGA 32 is configured to process the video and / or image data received from the machine 12 via the Ethernet connection 16.

[0075] In addition, the FPGA is coupled to the data memory 34 so that the received video and / or image data can be at least temporarily stored in the data memory 34.

[0076] In the embodiment shown, the machine 12 is also designed as an independent computing unit 36, i.e., as a standalone computer. In other words, the machine 12 is based on its own hardware.

[0077] Alternatively to the Figure 1 In the embodiment shown, in which the display device 24 is configured separately from the operating system-free device 14, the operating system-free device 14 can also be configured as part of a peripheral device, for example, as part of a radar device screen or as part of an electronic control strip system. In this respect, existing components of the air traffic control system 10 can be used to ensure the functionality of the operating system-free device 14.

[0078] Furthermore, it can alternatively be provided that the operating system-free device 14 itself is designed as a touch-sensitive device so that the operator or air traffic controller can make the corresponding inputs directly on the operating system-free device 14.

[0079] In addition, it can be provided that the operating system-free device 14 is connected to more than one display device 24 or touch-sensitive module 26.

[0080] The operating system-free device 14 can in principle receive several, in particular different, data sets of image and / or video data, which are transmitted to the different display devices 24 or touch-sensitive modules 26.

[0081] The operating system-free device 14 can also receive multiple, in particular different, data sets of image and / or video data, even though only one display device 24 or touch-sensitive module 26 is provided. The corresponding display can then be divided, which is also referred to as screen splitting. The areas after the optional screen splitting are in Figure 1 marked with "A" and "B" for example.

[0082] In principle, the air traffic control system 10 is designed such that the operating system-free device 14 can process different data contents that can be assigned to different air traffic control centers 20.

[0083] This means, for example, that different content can be displayed on multiple display devices 24. Thus, two or more display devices 24 can be coupled to the operating system-free device 14, so that the different content can be displayed on different display devices 24.

[0084] However, the different contents can also be displayed in different areas of a corresponding display on a display device 24, so that they are assigned to only one air traffic control center 20. An air traffic controller can then monitor several areas simultaneously.

[0085] In Figure 2 an alternative embodiment is shown which is not part of the claimed invention, which differs from the embodiment according to Figure 1only differs in that the machine 12 is not directly connected to the operating system-free device 14 via a peer-to-peer connection, but via an Ethernet connection 16 in which an intermediate system 38 is provided.

[0086] The intermediate system 38 is, for example, cloud-based, so that the intermediate system 38 is arranged within the network 18, for example the local network or the wide area network.

[0087] The intermediate system 38 generally ensures that several operating system-free devices 14 can be connected to the one machine 12.

[0088] If the air traffic control system 10 comprises an intermediate system 38, in particular a cloud-based one, it can be provided that several operating system-free devices 14 are coupled to the machine 12 via the intermediate system 38, so that the different contents of the video and / or image data can be transmitted to different operating system-free devices 14, which are in particular assigned to different rooms of the air traffic control system 10.

[0089] This makes it possible for different data contents to be sent to air traffic controllers working in different rooms in order to transmit the information to all air traffic control centers 20 of the air traffic control system 10. This is independent of where the corresponding air traffic control centers 20 are located, as long as they have access to the cloud-based intermediate system 38.

[0090] In Figure 3An embodiment of the air traffic control system 10 according to the invention is shown, which differs from the two previous embodiments in that two operating system-free devices 14 are provided, each associated with a display device 24 or a touch-sensitive module 26. The two operating system-free devices 14 are each connected to the at least one machine 12 via the intermediate system 38, as shown in Figure 3 emerges.

[0091] In the Figure 3 In the embodiment shown, the machine 12 is also designed as a virtual machine which does not have an independent computing unit 36.

[0092] As from Figure 3 As is clear, the virtual machine is provided in a data center 40 that includes multiple virtual machines. This can also be referred to as a server system.

[0093] The data center 40 or the (virtual) machine 12 can be part of a cloud, which generally ensures that the corresponding data can be accessed from outside.

[0094] In principle, several connections to or connections from different operating system-free devices 14 can be established simultaneously, as described in Figure 3 is also shown. This is particularly due to the provision of the cloud-based intermediate system 38, which is integrated into the network 18 via the corresponding Ethernet connections 16.

[0095] The different versions that are available in the Figures 1 to 3are shown, however, have in common that the machine 12, regardless of whether it is a virtual or a physical machine, is connected to the at least one operating system-free device 14 via the Ethernet connection 16, via which video and / or image data is transmitted in one direction and control commands in the other direction.

[0096] The video and / or image data received by the operating system-free device 14 are processed internally by the operating system-free device 14 and transmitted to a display device 24, which may be integrated into the operating system-free device 14 or may be designed separately from the operating system-free device 14.

[0097] In any case, the display device 24 is assigned to an air traffic control center 20 so that the received video and / or image data can be displayed to the operator or air traffic controller.

[0098] In principle, the air traffic control system 10 is thus configured to carry out a method for transmitting video and / or image data, in which, in a first step S1, video and / or image data are provided via the machine 12 on which the operating system is running.

[0099] In a second step S2, the machine 12 and / or devices associated with the machine 12 (downstream systems), such as radios, walkie-talkies, or the like, are controlled via the operating system-free device 14 using control commands to request video and / or image data to be transmitted. The machine 12 can forward the corresponding control commands to the devices connected to it, which then implement the control commands accordingly to provide the requested data. This is then again done via the machine 12.

[0100] The control commands are transmitted to the machine 12 via the Ethernet connection 16. This is done via corresponding inputs on the display device 24 or the touch-sensitive module 26.

[0101] In a third step S3, the requested video and / or image data are transmitted from the machine 12 or the source 22 assigned to the machine 12 via the Ethernet connection 16 to the operating system-free device 14 and processed by the operating system-free device 14.

[0102] In a fourth step S4, the video and / or image data transmitted and processed by the operating system-free device 14 are displayed on the display device 24, which is assigned to the operating system-free device 14, in particular is designed separately therefor or is integrated in the operating system-free device 14.

[0103] In the Figure 1In the non-inventive embodiment shown, the video and / or image data (as well as the control commands) are transmitted directly via the peer-to-peer connection, whereas in the embodiments according to the Figures 2 and 3 the intermediate system 38 is provided, via which the corresponding data (and control commands) are transmitted via the Ethernet connection 16.

[0104] In principle, a simply constructed and easy-to-maintain air traffic control system 10 is thus created, with which the video and / or image data can be transmitted in a simple manner.
