Definitions
- the invention relates to a method for detecting obstacles during operation of an aircraft, in which environmental data is detected using at least one sensor and visualized on at least one display, and in which a processing of the data is performed by at least one computing unit and a human-machine interaction of at least one arithmetic unit is controlled.
- the invention further relates to a device for obstacle detection in an operation of an aircraft, which has at least one sensor for detecting environmental data and which is provided with at least one display for visualizing the data, as well as the at least one computing unit for processing the data and at least one Computing unit for a human-machine interaction has.
- the invention is primarily designed for operation in motorized aircraft.
- the object of the present invention is to develop a method and a device of the type mentioned in the introduction in such a way that a high-quality and at the same time energy-efficient and economical obstacle recognition is supported.
- the device according to the invention is a distributed system in which several arithmetic units each assume a defined task in the entire system.
- Each computer uses an operating system.
- the operating system can also run on single-core processor architectures and therefore does not meet any special requirements of a multi-core processor. Furthermore, it does not have to meet the requirements of a real-time system.
- BUS Binary Unit System
- Each processor has an executable program which receives data from the BUS, processes it and sends its own data to the BUS.
- the arithmetic unit is connected to a bus to which the data is delivered and from which it receives data for processing.
- This display is designed as a head-up display and connected to a computing unit.
- This arithmetic unit receives data from the BUS using an executable program, processes and visualizes it on the display.
- the pilot By visualizing the data on a connected head-up display, the pilot has all the necessary information in his main field of vision.
- head-up display instead of the head-up display, other suitable displays for visualization can be used, such as a suitable for displaying electronic data glasses.
- control device connected to the BUS. In it, data are received by the bus and processed and transferred to the bus.
- the object of the control means is to set up the entire distributed system to control and formezu ⁇ provide data for visualization.
- the control device also has the task of ensuring human-machine interaction.
- Possible hardware variants for the control device are a tablet PC or another embedded system (“embedded system").
- Figure 1 A simplified representation of a variant of a distributed overall system as an overview
- Figure 2 shows another graphical variant of a distributed
- Figure 3 is a representation to illustrate a first variant of the procedure
- Figure 4 is a diagram illustrating another
- Figure 1 shows the three components "Head-Up Display", “Human Machine Interaction” and “Sensor Technology” (Variant A).
- Figure 2 shows that the invention by further components with defined tasks, here z. B. "data recording”, is extensible (variant B).
- FIGS 3 and 4 show an example of two implemented procedures.
- Figure 3 illustrates how an object detected by a sensor is processed and visualized on the head-up display.
- Figure 4 shows how an operator interacts with the system via the controller and retrieves this data from the computational units of other components, such as a computer. As head-up display and sensors, are received and processed.
- the invention operates with a single-processor system having at least one processor core. Advantages of this system compared to multiprocessor systems are a lower energy consumption and only passive cooling, since waiving the coordination between multiple physical processors, the required amount of computing power is much lower. Further advantages are a smaller size and lower costs.
- the object of the invention is, in particular, to capture data from the aircraft and its surroundings by means of peripherals, to process them and to visualize them on a head-up display.
- the pilot is visualized by the invention data indicating its current attitude. Being able to capture, combine and calculate data from the aircraft and its environment makes the application valuable to a pilot, because by calculating new data, for example, dangerous situations can be identified.
- Another object of the invention is to ensure the recording of all received data and the extraction of this data from the system.
- the application of the invention does not require actively intervening in the systems of the aircraft. It is a purely passive system that collects, processes and visualizes data.
- the aircraft used in the invention is in particular a motorized aircraft. According ei ⁇ ner embodiment is a plane.
- Figure 1 subtasks throughout the system and communicate data to each other over a BUS.
- the invention can be extended as shown in Figure 2 by other components with defined tasks - here: data recording on a separate data storage device.
- the new component is connected to the other components through the BUS.
- An object is detected by a sensor as shown in Figure 3.
- Data about the object is processed by a computing unit and passed on to other computing units via a bus.
- the data is received, for example, from the processing unit of the head-up display, to be visualized on the head-up display.
- the pilot interacts with the system via the controller as shown in Figure 4, e.g. a warning message is confirmed.
- the data of the control device are processed by a computing unit and passed on via a bus.
- the data is received and processed by the processing units of the components "Head-Up Display” and "Sensor Technology”.
- z. B the information shown in the display and the data processing in the component "sensors”.
- the control and configuration is located on a computer with user interface. This is connected to the network of decentralized computing units. Each of these computational units has a defined task to fulfill in the system and is therefore equipped with appropriate software. For example, the head-up display is connected to one of the arithmetic units. Data intended for this computing unit (HUD) are understood, processed, possibly processed and visualized.
- HUD computing unit
- Each of the arithmetic units is able to perform a specific task through its configuration. Furthermore, it is able to take over the tasks of other computing units, in which it is configured accordingly. Since the In ⁇ gence of the entire system to a decentralized distributed System, central processing and decision by a central unit is not necessary. For example, a failure of the MMI group still allows the rest of the system to parse critical values and display appropriate alerts on the HUD.
- One of the computational units of the system is responsible for providing the distributed system with configuration during the initial commissioning phase.
- the configuration contains the tasks, limit values and behavioral rules for data.
