[0002] The flight control panel is an indispensable part of the flight instruments of modern large airliners. As a part of the human-machine interaction unit, it is the main input device for pilots to control and operate. At the same time, it is also an important output device, usually used to display the operating status and important parameters of the system. Through the flight control panel, the pilot can manually complete most of the operations required for flight. For example, the TCAS / ATC control panel is a typical flight control panel.

[0003] Simulation is an imitation of the abstract attributes of a certain level of a real system. People use such a model for experiments, obtain the required information from it, and then help people make decisions on problems at a certain level of the real world. Flight control panel simulation is to use computer technology to model the control panel and simulate the input and output functions of real physical devices for system integration verification testing.

On the one hand, the modeling cycle is relatively long, and on the other hand, the response to demand changes is relatively slow. However, the time for system integration and verification is tight and the tasks are heavy. An effective modeling and simulation method must be available to discover problems in time, accurately locate the reasons, and quickly find reasonable solutions. Based on the requirements of the system development process, it has become increasingly important and urgent to build a fast and flexible control panel simulation method. Summary of the Invention

[0053] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention.

Unless otherwise defined, the technical terms or scientific terms used herein shall have the ordinary meanings as understood by those of ordinary skill in the art to which the present invention pertains.

Similarly, unless the context clearly indicates otherwise, the singular forms "a", "an" or "the" and similar terms do not denote a limitation of quantity, but rather indicate the presence of at least one.

[0055] Based on the technical problems in the prior art that when simulating a flight control panel through modeling, due to numerous configuration items in the flight control system, traditional control panel simulation models different configuration items separately, resulting in a long modeling cycle and slow response to demand changes; the present invention aims to disclose a simulation method, device and storage medium for a flight control panel. The method defines the display content and execution logic of the control panel through an XML file and a Python script file, realizes the generalization modeling of the control panel, supports dynamic loading, can quickly verify the correctness of the modeling, greatly shortens the control panel modeling time, and reduces the development cost.

[0056] The embodiments shown in the accompanying drawings are hereinafter combined to further specifically introduce the simulation method, device and storage medium disclosed in the present invention for a flight control panel.

[0057] The simulation method for a flight control panel provided by the present invention includes creating a system framework, initializing an SOA componentization engine, and loading the functional modules of the system; wherein, the functional modules include an engineering management module, an ICD management module, a control library module, a simulation panel editing module, a simulation panel execution module, a data processing module, and a data channel module; reading an engineering configuration file, initializing engineering nodes, ICD data, and device boards; reading configuration parameters, initializing the data channels of the device boards, enabling data functions, and starting to listen for channel data; reading a panel configuration file, initializing the control panel and displaying it, preparing a script execution context, and executing initialization logic; starting a listening thread to listen for user operation events and data message events.

[0058] The system framework created in this embodiment is as Figure 1 shown, wherein, the engineering management module is used to achieve unified centralized management of simulation panels for different types of cockpits through an engineering management method; the ICD management module is used for visual editing of ICDs and importing / exporting ICD description files, supporting visual editing of ICDs, and the content that can be edited includes data format, data content, field attributes, etc.; the control library module is used for configuring and managing the basic control units in the flight panel, and users can build a target control panel through the basic control units provided by this module; the simulation panel editing module is used for customizing the display content of the simulation panel and editing the execution logic of the simulation panel; the simulation panel execution module is used for dynamically loading the layout file of the control panel and displaying the control panel, and at the same time, it can execute simulation logic according to the panel input and output; the data processing module is used for generating a structured ICD instance according to the ICD description information, and providing ICD serialization and ICD deserialization functions; the data channel module is used for configuring and managing multiple types of data channels, and can complete functions such as adding, deleting, modifying, querying, starting and stopping, and data sending and receiving of data channels. Moreover, the engineering management module, the ICD management module, the control library module, the simulation panel editing module, the simulation panel execution module, the data processing module, and the data channel module are developed in a componentized manner, and there is loose coupling between each module; wherein,

[0059] Specifically, the control library module includes common control units in an aviation control panel, such as buttons, binary switches, DIP switches, rotary encoders, digital tubes, indicator lights, multifunctional keyboards, etc.; among the above controls, operation-type controls all support sending user operation events, and display-type controls all support responding to display events. The user operation events and display events are defined as follows Figure 2(a) and 2(b)As shown. Moreover, when the user operates the controls in the simulation panel, the controls generate user operation events. When the simulation panel execution module monitors a user operation event, it calls the user event handling function in the script to complete operations such as message definition, message serialization, and message sending; when the simulation panel execution module monitors a data message event, it calls the data message handling function in the script to complete operations such as message deserialization, display event definition, and display event sending; when the control panel monitors a display event, it calls the property setting function of the corresponding control to complete the modification of the control display content.

[0060] In addition, the control library module can load user-defined control units developed according to specifications. For example, Figure 3 As shown, the embodiment defines a feasible base class, and users can inherit this base class to develop custom controls. Among them, setProperyValue() is the control initialization interface, and the initialization of basic properties has been implemented in the base class. Each custom control needs to implement it by itself according to the extended properties; getProperyValue() is the interface for obtaining the control property value, which is used for the sending script to obtain the control property information, and each custom control needs to implement it according to the situation; showAction() is the display event handling interface, and each custom control needs to implement it according to the situation; sendAction() has been implemented in the base class, and it generates a user operation event after being called, and each control calls it according to the situation. During real-time operation, the control library module provides a control instantiation interface to the system through the service interface, and the instantiation interface is defined as Figure 4 As shown.

[0061] The simulation panel editing module describes the layout information of the simulation panel through an XML format file. Specifically, the XML layout file includes a file root node PanelRootGroup, which contains multiple Panel nodes; the Panel node describes the attribute information of the simulation panel, including the name, associated script, associated data channel, and control (Item node) position information; the Item node describes the attribute information of a single control, including type, name, position, size, and other private attribute information. The simulation panel editing module describes the execution logic of the simulation panel through a Python script file. Specifically, the Python script uses a templated definition, and this script contains a user operation event response processing function doAciton and a data message event response processing function processPacket. In the response processing function, the getIcdPacket can be called to obtain the ICD instance, the getProperty can be called to obtain the control property value, the sendPacket can be called to serialize and send the ICD data, the analysePacket can be called to deserialize the ICD data, and / or the setProperty can be called to construct and send an echo event; the panel layout description and logic file can be directly edited in a text editor. During operation, the simulation panel execution module constructs the display and control panel by loading and running the XML layout description file, and realizes the control response and echo logic by loading and running the panel Python logic file through pybind11.

[0062] The data processing module provides ICD instantiation, ICD serialization, ICD deserialization interfaces, etc. to the system through the service service interface. The definitions of each interface are as follows Figure 5 As shown; it can be seen from the interface that in this implementation, the ICD instance is described by a JSON format string as the ICD information exchange protocol between C++ and Python.

[0063] The data channel module supports access to discrete quantity boards, ARINC429 boards, ARINC664 boards, RS422 boards, RS485 boards, CAN boards, Ethernet boards, and other various device boards. For the above-mentioned hardware with communication functions, the physical communication interface is converted into a data channel in the data channel module. After initializing the channel, it is registered to the communication data bus. The principle is as follows Figure 6 As shown. The main functions included in the data channel interface are: setting the channel interface identifier, obtaining the channel interface identifier, opening the channel, closing the channel, writing data, reading data. The functions included in the data bus interface are: obtaining all channel lists, obtaining a channel with a certain Id, registering a channel, unregistering a channel, writing data to a single channel, reading data from a single channel, writing data to multiple channels, reading data from multiple channels. The UML interface design diagrams of the data channel and the data bus are as Figure 7 and Figure 8as shown

[0064] When the above data channel receives message data, it calls the data identifier parsing script to parse the data packet identifier; then determines the ICD information of the message data through the ICD binding table, and packages the ICD information and the message data into a data message event and sends it to the simulation panel execution module. The matching process of the ICD is as follows Figure 9 as shown. The data channel module defines the relationship between the ICD and the data packet identifier through the ICD binding table, and the data packet identifier is dynamically parsed through the data channel association script.

[0065] According to the read panel configuration file, the steps for initializing and displaying the control panel include the following

[0066] Step 1, read the control panel XML layout file, parse the attribute description information of the control object, and form a control object list;

[0067] Step 2, traverse the control object list, and sequentially call the control instantiation interface provided by the control repository module to instantiate the control object according to the control object type, and initialize each control according to the attribute description information of the control object, including position, size, and display style;

[0068] Step 3, start the display event listening thread to listen for display events.

[0069] According to the read panel configuration file, the initialization steps for the simulation panel execution module to prepare the script execution context and execute the initialization logic are as follows

[0070] Step 11, use the pybind11 function to import the Python basic running module and set the Python script index directory;

[0071] Step 12, expose the ICD instantiation, ICD serialization, and ICD deserialization interfaces of the data processing module and the data sending interface of the data channel management module to the Python running context through the pybind11 function;

[0072] Step 13, read the Python script path information associated with the control panel, use pybind11 to load the script, and check whether the script conforms to the template specification; if it does not meet the specification requirements, prompt the user; if it meets the specification requirements, execute the initialization logic in the script.

[0073] Another embodiment of the present invention discloses a simulation device for a flight control panel. When the device runs, it implements the above-mentioned simulation method for the flight control panel. The simulation method for the flight control panel can be divided into multiple modules or units when executed.
