Description

Technical Field

[0002] With technological innovation and the increasing complexity of airborne systems, the traditional R&D model based on closed internal network collaboration is becoming increasingly unsuitable for airborne system applications. Establishing an airborne system collaborative R&D ecosystem based on the airborne industrial internet can provide a unified basic information platform for the R&D of civil aircraft airborne systems, achieving an industrial ecosystem that fully integrates information technology and airborne system development.

[0003] Simulation is a crucial step in the forward development of airborne systems. It can identify design flaws early, reducing the iteration cycle after product development. To avoid the high modification costs and extensive iteration time associated with physical design errors discovered during the system integration testing phase, and to address the difficulty of integrating and verifying products developed by remote airborne units during joint simulation, existing methods use a hierarchical hybrid clock synchronization method to synchronize the clocks of the hardware-in-the-loop simulation interface and the simulation system within the same local area network environment. However, this still fails to achieve remote hardware-in-the-loop joint simulation. Summary of the Invention

[0055] The following embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0056] It should be noted that, unless otherwise specified, the technical or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.

[0057] like Figure 1 As shown, the embodiment of the present invention discloses a remote adaptation method for a simulation center, which is applicable to an ARINC664 interface airborne device, including:

[0058] S101, parse the ARINC664 bus protocol data packet into output variables to interact with the bus. Figure 2 Shown, including:

[0059] Obtain the virtual link number; after identifying the AFDX port number, obtain the FDS by identifying the FDS ID and, consequently, the FDS frame data set; parse the frame data to generate an array. To enable interaction with the bus, the ARINC 664 bus protocol data sent by the physical device under test is generated into an array through the above steps, allowing the data to be read by the simulated bus.

[0060] S102: Configure the mapping relationship between output and input variables and bus parameters.

[0061] S103. Generate ARINC664 interface adaptation code: read the data mapping table, read data from the data bus and submit it to the data bus, and accept scheduling instructions.

[0062] S104: Encapsulate the ARINC664 interface adaptation code to generate an executable simulation task.

[0063] Furthermore, the method further includes step S5, which is used to receive a satellite timing signal, specifically including:

[0064] Based on the precise clock information of the received satellite timing signal, the ARINC664 interface data is timestamped;

[0065] The simulation center obtains interface data through a dedicated network and calls timing resources to achieve clock unification between the ARINC664 interface and the virtual integration and simulation verification system.

[0066] Based on the precise clock information provided by the received satellite timing signals, input and output interface terminals can time-stamp ARINC 664 interface data in real time. The Industrial Internet-based simulation center retrieves interface data through a dedicated network and calls timing resources to achieve clock synchronization between the ARINC 664 interface and the virtual integration and simulation verification system, improving the real-time performance of remote co-simulation of ARINC 664 interface physical devices.

[0067] Optionally, the adaptation method includes driving an Ethernet network to encapsulate input variables into bus protocol packets for stimulus input and fault injection into the airborne device under test. The Ethernet network driver remotely connects the executable simulation task to the simulation center via the Industrial Internet private network, completing the reception of ARINC 664 interface data from the simulation bus and the stimulus input and fault injection into the physical device under the ARINC 664 interface. Receiving the input stimulus or fault injection into the physical device under test is the reverse process of step S101.

[0068] In one embodiment, based on Figure 3 The physical architecture shown provides a remote real-time co-simulation method for equipment in different locations, which is applicable to airborne physical equipment with ARINC664 interface. Figure 4 ,include:

[0069] S201: Generate a device-side executable simulation task, which is generated based on the aforementioned remote adaptation method of the simulation center. This method uses the same inventive concept as the aforementioned remote adaptation method of the simulation center and can achieve the same beneficial effects, so it will not be repeated here.

[0070] S202: The remote user configures the simulation resources required for the current hardware-in-the-loop joint simulation environment as needed. The simulation resources are configured using the following method:

[0071] Remote users configure the semi-physical joint simulation environment based on user authority control, call the model adapter and the virtual integration and simulation verification system of the simulation center through the virtual cloud desktop, and configure on demand to form a joint simulation environment for the current ARINC664 interface airborne equipment.

[0072] S203. Upload the device-side executable simulation task and the model-side executable simulation task to the configured simulation environment via the industrial Internet private network. The model-side executable simulation task is implemented by a remote user using a virtual cloud desktop to call the model adaptation service provided by the simulation center. The remote user completes the following operations based on the model adaptation task:

[0073] Import the model, automatically analyze the SCADE / Simulink model, and extract the model interface information: what parameters and inputs and outputs the model requires, such as data types, initial values, and other specific parameters.

[0074] Configure the mapping relationship between input and output variables and data in the real-time bus.

[0075] Automatically generate adapter code: read the data mapping table, read data from the data bus, submit the results to the data bus, and accept scheduling instructions;

[0076] Automatically encapsulate the model and adapter code to generate simulation tasks that can be executed on the model side.

[0077] S204: The remote user at a different location sends a simulation control command to implement simulation.

[0078] All simulation tasks are sent to the real-time simulation bus for scheduling. Before performing a specific simulation, the relevant parameters of the simulation project must be configured. Remote users can call the simulation configuration and control components to achieve the following functions:

[0079] 1) Configure the relevant parameters of the simulation project, such as the full-speed and real-time modes of the bus, the synchronization period of the simulation; configure the parameters of each simulation task, such as synchronous or asynchronous mode, the synchronization period interval in synchronous mode, remote or local mode, and background display or hiding;

[0080] 2) Control the running status of each simulation task, such as start, pause, stop, single step and other operations.

[0081] Furthermore, the remote user gives simulation control commands, such as start, pause, stop and other control commands, to control the running status of the simulation task.

[0082] The real-time simulation bus is developed based on virtual shared memory and combined with a data read and write synchronization mechanism. Each simulation task runs as an independently running application, and the read and write operations of the shared memory are processed separately to ensure the coordinated operation of the joint simulation.

[0083] The simulation task obtains simulation control instructions from the bus and executes simulation behaviors, including initialization, restart, and loading specified scenarios. The simulation task can also obtain the required input data from the bus and submit the output results of the simulation run to the bus.

[0084] The scheduling process of the real-time simulation bus will reserve resource space based on the priority attributes of each simulation task to ensure that high-level tasks can complete simulation control instructions first and are not blocked by other tasks.

[0085] Furthermore, the remote real-time joint simulation method for devices at different locations further includes:

[0086] Monitor ARINC664 interface data in real time, and filter and display ARINC664 interface data within the simulation cycle after the simulation is completed.

[0087] Remote users can call the data acquisition and monitoring component to select the ARINC664 interface data or model output parameters to be monitored and display them graphically. After the simulation is completed, remote users can call the simulation data analysis and processing component to select the ARINC664 interface data or model output parameters to be monitored and filter and display them.

[0088] In one embodiment, an adaptor is provided, see Figure 5 ,include:

[0089] Parsing module, used to parse ARINC664 bus protocol data packets into output variables to interact with the bus;

[0090] Mapping module, used to configure the mapping relationship between output and input variables and bus parameters;

[0091] A generation module is used to generate ARINC664 interface adaptation code: read the data mapping table, read data from the data bus and submit it to the data bus, and accept scheduling instructions;

[0092] The encapsulation module is used to encapsulate the ARINC664 interface adaptation code and generate executable simulation tasks.

[0093] Optionally, the parsing module is specifically configured to:

[0094] Get the virtual link number;

[0095] After identifying the AFDX port number, obtain the FDS by identifying the FDS ID and then obtain the FDS frame data set;

[0096] Parse the frame data and generate an array.

[0097] Optionally, the terminal further includes a time synchronization module, specifically configured to:

[0098] Based on the precise clock information of the received satellite timing signal, the ARINC664 interface data is timestamped;

[0099] The simulation center obtains interface data through a dedicated network and calls timing resources to achieve clock unification between the ARINC664 interface and the virtual integration and simulation verification system.

[0100] Optionally, the terminal further includes an Ethernet network driver module, which is specifically used to encapsulate input variables into bus protocol data packets to perform stimulus input and fault injection on the airborne device to be tested.

[0101] The input / output interface terminal 20 provided in the embodiment of the present application and the remote adaptation method of the above-mentioned simulation center adopt the same inventive concept and can achieve the same beneficial effects, which will not be repeated here.

[0102] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
