Detailed Description

The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

Example 1

The embodiment introduces a model-based visual missile defense penetration probability verification method, which comprises the following steps:

judging whether interception is successful or not according to the size of miss distance by tracking anti-ship missiles and interception missiles launched in advance;

The invention provides a model-based visual missile defense penetration probability verification method, which adopts model-based system engineering, utilizes the advantages of MBSE, computer technology and virtual reality technology, and converts the design of missile complex system equipment into missile development from a document-based mode to a method taking a model as a design concept. The method is characterized in that documents, design specification manuals and design interface descriptions required in the design process of a missile complex system in the past are abandoned, the traditional low-efficiency work design method is changed, the advantages of an integrated model in missile design are exerted by establishing a modularized, normalized and digitized basic model and a service logic model for the missile system, the integrated model is used for supporting the completion of a series of activities such as requirement analysis, part design, detail optimization, application scene planning and efficiency evaluation in the design process of the missile system, and meanwhile, the activity feedback and verification among interactions can be supported. The missile system is designed by combining a virtual reality technology and is displayed in a visual mode, interactive and immersive design experience is provided, and the missile system can be used in the fields of missile design feasibility verification, design demonstration, cognitive tests and the like.

As shown in fig. 5, the application process of the visualized missile defense probability verification method based on the model provided by the embodiment specifically involves the following steps:

step one, based on a real battlefield environment, a virtual reality carrier-based aircraft missile launching scene is constructed by utilizing an open source engine UE 4. The construction of the virtual natural environment comprises the following steps: terrain, virtual vegetation, roads, electromagnetism, clouds, etc. The development of the scene is performed by the UE4 engine, which mainly includes the following important components: three-dimensional terrain model creation, meteorological model creation such as illumination and the like, and vegetation coverage rendering. In order to make the constructed scene terrain more realistic, the elevation data of the DEM is used for realizing the elevation data, and the terrain is adjusted through a terrain editor carried by the UE4, so that the constructed virtual terrain and the real terrain keep basic consistency. The process flow of constructing the virtual three-dimensional terrain model is shown in fig. 6. The method mainly comprises the steps of selecting DEM elevation data of a required geographic position through geospatial data cloud selection, reading the downloaded DEM elevation data by using a GlobalMapper, intercepting a required area, selecting a rendering mode as gradient rendering, displaying an elevation gray-scale map used by terrain software at ordinary times, recording the required minimum and maximum altitudes and areas, exporting an hfz format file, importing the file into World Machine for processing, and selecting the derived elevation map format as RAW16 after the processing is finished. The terrain is then created in the UE4 after the terrain is processed. New terrain creation is selected in the UE4 and import from a file, into which we process the raw file. Wherein, the value of X, Y and Z in Scale here, we can click "Fit To Data" To adjust automatically To Fit the Data, and finally click "Import" To Import. In order to make the terrain more realistic, the material of the vegetation is constructed for rendering the terrain in later period. The texture of the texture is superposed by multiplication through two texture maps, multiplication is carried out by using a texture node multiplex, the node can automatically adapt to the input parameters, if two vectors are input, the operation of the vectors is carried out, and if the vectors are scalar, the common algebraic multiplication is carried out. To maintain the realism of the vegetation we also need to use SimpleGrassWind material nodes to simulate the effect of grass being blown by wind. The manufactured material ball is used for rendering the terrain, a real geographic space environment is constructed by manufacturing a cloud layer effect, and light sources such as solar illumination are added to complete the construction of a virtual combat geographic environment scene.

And step two, establishing a missile launching system model and a behavior model thereof, wherein the missile system comprises a dynamic model, a missile guidance model, a target model and an environment model inside the missile. The dynamic model comprises a pneumatic model, an oil cylinder model, a quality calculation model and a ballistic planning calculation model. The GNC model of the missile may in turn consist of a GPS, guidance and control model. The environment model mainly comprises a gravitation model and an atmosphere model. And modeling the carrier-based aircraft body. The main body of the fuselage is composed of cuboids in a standard basic model, and the model is built through three basic elements of points, lines and surfaces in a polygon modeling mode. The specific operation is dragging a basic model cuboid in a scene, clicking a right mouse button on the dragged three-dimensional model, selecting 'converting into an editable polygon' operation from a menu bar, selecting modes such as points, edges, elements and the like under the 'editable polygon' command for further processing, and establishing a three-dimensional model of the automobile body after the processing, wherein the three-dimensional model is shown in the figure below. And constructing a wing empennage for the fuselage model. In the construction of the three-dimensional model of the wing and the empennage, Boolean operation (BOOLEAN) is mainly applied, namely two or more objects are overlapped, and the operations of addition, subtraction and intersection of the objects are further realized. In the modeling process of the wing and the empennage, firstly, a cuboid with a corresponding size is created in a view, the side surface of the cuboid is extruded to form the concave-convex feeling of a specific part of the wing, and the empennage part is subtracted from the cuboid by Boolean operation.

And thirdly, constructing a ship-borne missile penetration control system model by using Magicbraw system modeling software based on a real battlefield environment. When a very complex problem needs to be solved, the problem can be decomposed into a plurality of small problems to be solved one by one, so that the workload cost for solving the complex problem can be reduced, and the method is the basis of modular modeling. The missile system is used as a crucial ring in the design of a weapon equipment system, plays an important role in the field of defense and military, and the research and improvement of the missile system are the key points of the research, but the missile system is not complex, and comprises a plurality of complex small systems, so that the research is required, at least in the traditional sense, the mathematical equation or the kinetic equation can be accurately described clearly without the traditional meaning, even if the structure of the missile system is constructed by using a mathematical model, the functional disorder can be caused, the model is not easy to understand, and therefore, each small system with independent functions needs to be decomposed, the simplification processing is carried out under the condition of meeting the design requirement, and the complete closure of the missile system is ensured.

For functional decomposition or complex small system decomposition of the missile system, an object-oriented method can be adopted, the object-oriented method can be understood as an object which abstracts different transactions into interaction according to different characteristics of the transactions, and the interaction objects can be regarded as basic units forming the system, so that the functional decomposition of the whole system can be realized by using the object. For example, a missile launching system of a ship-borne aircraft is divided into two main components: the system comprises two independent functional modules of a carrier-based aircraft system and a missile system. According to the two use cases, a corresponding MBSE model is independently developed, and a corresponding module definition graph, a parameter graph, an activity graph and the like are developed and used for capturing parameters (or attributes) related to the inside of the MBSE model and internal states related to the implementation functions. Task scenarios are modeled using activity or sequence diagrams. The activity partitions (also called swimlanes) in the activity diagram or the life lines in the sequence diagram represent the system, external systems, and users. For the missile system model, a task scene is represented by an activity diagram. The active partition is a preliminary logical subsystem.

Taking the missile launching process as an example, firstly, the missile is initialized, the flight control system and the cruise system are initialized and confirmed, and the initialization state is judged by using a Decision Node in the SysML language, which is shown as a diamond in the figure. Two selection buttons appear when the program runs for simulating whether the initialization is successful. If the initialization is in a problem and the system does not finish the initialization, the information state is returned. And after the initialization of the two systems is completed, the initialization completion state information is transmitted out, and then the propulsion system carries out the target driving action.

And fourthly, calculating missile penetration probability, and performing a simulation experiment by using a Monte Carlo method, wherein the number of penetration warheads is the final expected sample, and the sample is the result of one penetration experiment. The sample values are considered functions of random variables, which are then real functions defined over a number of different event spaces, with a certain probability density. The event directly influencing the quantity of the penetration warheads is a warhead intercepted event, and the intercepted event is related to event discovery, event tracking and event identification and is also related to the quantity of the intercepted warheads of an intercepting party and an intercepting strategy.

The simulation process of the attack and defense confrontation of the ballistic missile and the interception missile is as follows:

firstly, setting the launching point position of the anti-ship missile and the target position, and taking the target position as the position of a defense system and the launching point position of the ship-air missile. Simulating an anti-ship missile trajectory through the established anti-ship missile model, and inputting the trajectory data into a defense system model;

designing the maximum distance R detected by a defense radar system, and when the anti-ship missile enters a radar detection range, starting to read the missile path data of the anti-ship missile by a radar;

and thirdly, determining a preset interception height H, and predicting trajectory information behind the anti-ship missile through a radar to obtain the position of a predicted interception point P. And ballistic information of the anti-ship missile reaching the P position;

fourthly, calculating the launching data of the ship-air missile according to the predicted interception point;

and fifthly, launching the interception missile, tracking the anti-ship missile and the interception missile through the radar, finally judging whether interception is successful according to the size of the miss distance, and if interception is successful, ending. If the interception fails, the anti-ship missile hits the target;

and sixthly, outputting a confrontation result, wherein the confrontation result comprises whether interception is successful, miss distance, real interception point position information, intercepted projectile trajectory information and the like.

And step five, developing a joint simulation framework. The driving interaction of the SysML model to the model in the VR scene is realized by developing a joint simulation framework as shown in FIG. 1. The interoperation interface between Magic Draw and UE4 in the architecture adopts UDP for communication, so that for Magic Draw, plug-in development is required, and the plug-in Magic Draw Project is used for acquiring states and signals in system simulation and sending the states and signals out; the development of the Server communication Server mainly realizes the functions of client login, message receiving and forwarding, receives the message sent by the Magic Draw and forwards the message to the UE 4; the C + + development mode of the UE4 is needed to be used in the UE4, a class for realizing UDP communication is added to the UE, an Actor named MyUDPClient is created in a project, communication in a blueprint is realized through the Actor, signals are received and judged, corresponding events are triggered, and corresponding functions are executed; the framework comprises output equipment which is mainly used for showing the virtual reality of the system. The Server communication development framework is shown in fig. 7 below, and the Server adopts a C # programming language for development, realizes Socket programming, and realizes single-to-multiple conversation through UDP communication. The IP address of the host is bound, the Port number Port is set to be 9999, then the addresses of the client UE4 and the Magic Draw in the same local area network are bound, thread calling is carried out, and the UDP data message is received and forwarded. The following is a part of codes in the program, mainly a process of communication connection between the server and the client.

Reading the IP address and Port number specified in the configuration file:

ServerIp＝ System.Configuration.ConfigurationManager.AppSettings["ServerIp"]；

ServerPort＝ System.Configuration.ConfigurationManager.AppSettings["ServerPort"]；

binding IP address and port number:

IPEndPoint ipEndPoint＝new IPEndPoint(IPAddress.Parse(ServerIp), int.Parse(ServerPort))；

serverSocket.Bind(ipEndPoint)；

thread calling, receiving UDP data message:

serverSocket.BeginReceiveFrom(byteData,0,byteData.Length, SocketFlags.None,ref epSender,new AsyncCallback(OnReceive), epSender)；

the Server communication data structure is as follows:

the client logs in the server:

client- > server login: begin | Login | ClientName | End

Server- > client reply: begin | LoginOK | ClientName | End

The client logs out:

client- > server log-out: begin | LoginOut | ClientName | End

Data transmission:

client- > server sends control command:

In the co-simulation process, Server is the bridge for communication between Magic Draw and UE 4. The Server operates in the same LAN as Magic Draw and UE4, and is an "intermediate station" for communication between devices in the LAN, where all messages are aggregated and forwarded. And monitoring the message in the channel all the time in the operation process of the Server, analyzing the received information, and forwarding the message to the corresponding client according to the information obtained by analysis. Another important function of the Server is to monitor and manage the registered devices, and the Server monitors the active devices in the lan and displays the list of devices for device management. In the message interface, the content from communication among different devices can be observed, so that an operator can conveniently observe the communication content and find problems in time.

Step six; a MagicDraw plug-in was developed. The plug-in is selected to be developed in Eclipse, and an Eclipse environment for modeling tool development is set. The configuration of the development environment is mainly divided into the following steps:

(1) eclipse SDK is installed.

And starting Eclipse IDE, typing Eclipse SDK in a filter box in All Available Sites, clicking to select Eclipse SDK, and clicking Next to install the software.

(2) Pre-configured items of software are imported.

The software provides a pre-configured Eclipse project, is positioned in openapi under a software installation directory, and imports a java file Eclipse.

(3) The MAGIC _ DRAW _ INSTALL _ direct link is set.

Right-clicking MAGIC _ DRAW _ INSTALL _ DIRECTORY link, then selecting Properties, selecting Resource in an open dialog box, clicking Edit button, entering an Edit link address dialog box, enabling the link to point to our Magic Draw installation DIRECTORY, and clicking OK to complete link setting after selecting the installation position.

(4) Selecting Target platform.

When the software is subjected to plug-in development, firstly, a Target Platform of a project is selected, a MagicDraw project is expanded, then a Target definition file MagicDraw blocks + Running Platform is opened, and a Set as Target Platform is clicked. To this point Eclipse is ready for a plug-in code development and run/debug environment.

Finally, the packaging plug-in is stored in a specified directory.

Step seven; UE4 communication development. Firstly, a C + + class named UDPClient is added into a project file browser of UE4, a father type of the C + + class is selected to be an Actor, and corresponding h files and cpp files are automatically added into a project source file after the C + + class is added. The Visual Studio 2010 is used to open project source files and develop UDP functions.

The Sockets module of the UE4 encapsulates the socket, and first includes the socket.h in the udpclient.h file, and calls the socket module. The UDP communication function required by the project is realized by writing the constructor, and the specific constructor name and the function method are as follows:

(1) BeginPlay (): for obtaining the IP and Port numbers of the server and client.

(2) InitSocket (): the Port number of the UE4 is 8001 for binding the IP of the UE4client and the Port. And setting the buffer size, checking the buffer interval time, and binding a callback function for receiving the message.

(3) OnUdpDataReady (): for the reception and decision of data. Defining a data receiver receiveData, judging the received data to see whether the data is the message of the established communication structure, so as to effectively delete the message and avoid the phenomenon that the received data is copied to the receiver due to the overlarge receiving amount caused by the redundancy of the data.

(4) SendToServer (): for sending messages to the Server. Establishing an internet addr address based on a platform, binding Ip and Port of a Server with the internet addr address, judging whether the Ip and Port are effective or not, and if the Ip and Port are effective, transmitting a message to be sent out through a function.

(5) EndClient (): the user UE4 sends "logout | UE4 Client" to the Server, exits the Server Server on behalf of the UE4, and ends the UDP communication.

Step eight; to make the entire design more visible so that designers get an immersive design visualization verification experience, the developed UE4 project is integrated onto the VR hardware device HTC vive.
