Description

Technical Field

[0001] This invention relates to the field of simulation. More specifically, it relates to a simulation system, method, device, and medium based on combat behavior trees. Background Technology

[0002] Combat behavior models are a reflection of human factors in simulation systems, including situational awareness, behavioral decision-making, behavioral execution, and information interaction. They are crucial elements in system-on-systems confrontation simulations. To meet the needs of joint simulation experiments involving multiple branches of the armed forces, the combat methods, command decisions, and combat rules vary among these branches. This is especially true when researching joint operational tactics, where the construction of combat models becomes more complex. Combat models are flexible and adaptable to different combat scenarios, targets, and conditions.

[0003] Traditional modeling methods are generally rule-based, simulating combat behavior by configuring key parameters. This approach has certain limitations. Since users can only edit the parameters of the combat model, when the combat rules or logic change, a new model must be built. It is difficult to simulate the complex and ever-changing behavior of combat entities in a comprehensive manner, resulting in low model reusability. In addition, complex behavioral models built based on state machines are complex to model, and their reusability and scalability are also limited. Summary of the Invention

[0030] To more clearly illustrate the present invention, the following description, in conjunction with embodiments and accompanying drawings, further explains the invention. Similar components in the drawings are indicated by the same reference numerals. Those skilled in the art should understand that the specific description below is illustrative rather than restrictive and should not be construed as limiting the scope of protection of the present invention.

[0031] Existing combat behavior modeling systems have the following shortcomings:

[0032] 1) The lack of formal description of the specific processes of combat behavior is not conducive to the transfer, reuse and sharing of combat behavior models;

[0033] 2) The lack of an effective model reuse mechanism limits the established combat behavior models to a limited number of platforms;

[0034] 3) Lack of support for complex combined combat missions makes it difficult to represent the dynamic processes of equipment;

[0035] 4) The modeling process based on finite state machines and other methods is too complex.

[0036] In view of this, one embodiment of the present invention provides a simulation system based on a combat behavior tree, such as... Figure 1 As shown, the system includes a combat behavior modeling module, a combat behavior description module, an atomic combat behavior model library, a combat behavior model secondary development library, and a combat behavior execution engine module, wherein...

[0037] The combat behavior modeling module is used to provide an editing canvas and to edit the combat behavior tree structure in response to user operations;

[0038] The combat behavior description module is used to generate a behavior tree description file by formatting a description based on the combat behavior tree structure output by the combat behavior modeling module.

[0039] The atomic warfare behavior model library is used to store atomic warfare behavior models to obtain an atomic behavior library;

[0040] The combat behavior model secondary development library is used to dynamically extend the atomic combat behavior model to obtain a combat behavior model extension library.

[0041] The combat behavior execution engine module is used to receive the behavior tree description file and call the atomic behavior library and the combat behavior model extension library.

[0042] This embodiment achieves fully autonomous combat behavior modeling by setting up a combat behavior modeling module, improves the efficiency of combat behavior modeling by setting up an atomic combat behavior model library, and enhances the scalability and reusability of combat behavior modeling and simulation by setting up a combat behavior model secondary development library. The combat behavior models generated by the combat behavior modeling module and the combat behavior models in the atomic combat behavior library are reusable and scalable. Users can edit or recreate combat behavior models based on existing ones, which improves modeling efficiency and model reusability.

[0043] In one specific embodiment, the combat behavior modeling module provides an editing canvas where users can edit combat behavior tree nodes, connect nodes, automatically format the layout, and import / export the combat behavior tree.

[0044] Each combat behavior tree node includes the node type, node name, and upstream and downstream connection control points. Users can connect two behavior tree nodes by selecting the control points of two nodes.

[0045] In one specific embodiment, the tree description file stores the combat behavior node type, combat behavior node name, combat behavior node parameters, and the connection relationship of the combat behavior nodes, and specifies the execution order of the behavior tree nodes through the connection of the behavior tree nodes.

[0046] In one specific embodiment, a JSON file, an XML file, or a database is used to describe the combat behavior tree, thereby describing the combat behavior node type, combat behavior node name, combat behavior node parameters, and the connection relationships between combat behavior nodes.

[0047] The following example uses a JSON file to illustrate the description of a combat behavior tree:

[0048]

[0049]

[0050] Among them, OperationNodeType is the type of combat behavior node, OperationNodeName is the name of combat behavior node, and OperationNodeParameters are the parameters of combat behavior node.

[0051] In one specific embodiment, the combat behavior description module uses a database or a markup language file for storage. The data file generated by the description can be imported and exported by the combat behavior modeling module, and can be run through the combat behavior execution engine module.

[0052] In a specific example, the atomic combat behavior model is an indivisible and reusable combat behavior model, including root node, sequence node, selection node, condition judgment node, negation node, subtree node, repeat node, delay node, start mission node, stop mission node, sensor power-on node, sensor power-off node, weapon launch node, and jammer activation node.

[0053] In a specific example, to improve the reusability and richness of the combat behavior model, the combat behavior model secondary development library provides header files, static link library files, and dynamic link library files required for secondary development, supporting the expansion of the combat behavior model library through dynamic link libraries.

[0054] The header files required for secondary development have the file extension .h, the static link library files have the file extension .lib or .a, and the dynamic link library files have the file extension .dll or .so.

[0055] It should be noted that the expanded combat behavior model library can be edited and described in the combat behavior modeling module, and can be called and executed by the combat behavior execution engine module.

[0056] In one specific embodiment, the combat behavior execution engine module includes an executable program module and a secondary development library module. The executable program module provides an interface for running the combat behavior tree, and the secondary development library module is used to embed the combat behavior execution engine into other executable programs in response to user operations, enabling secondary customization development.

[0057] In one specific embodiment, the combat behavior execution engine module takes the combat behavior tree description file output by the modeling module as input, calls the atomic behavior library and the combat behavior model extension library, and performs simulation operation on the combat behavior model.

[0058] It should be noted that the execution process of the combat behavior model is the execution of the combat behavior tree, and the basic order of execution of the combat behavior tree is from top to bottom and from left to right.

[0059] In one specific embodiment, the combat behavior execution engine module includes an executable program module and a secondary development library module, wherein,

[0060] The executable program module is used to provide users with an interface for running the combat behavior tree;

[0061] The secondary development library module supports embedding the combat behavior execution engine into other executable programs for secondary customization development.

[0062] A second embodiment of the present invention provides a simulation method based on a combat behavior tree, such as... Figure 2 As shown, including,

[0063] Perform combat behavior modeling, and use the combat behavior modeling module to create, edit, import and export combat behavior models;

[0064] Expand the combat behavior model library by extending the combat behavior models through a secondary development library;

[0065] Run the combat behavior model, call the secondary development interface to run the combat behavior tree, or use the executable module to run the combat behavior tree.

[0066] In one specific embodiment, the process of editing the combat behavior model using the combat behavior modeling module can be saved, and the saved combat behavior tree model can be imported and exported.

[0067] It is worth noting that the process and principle of the simulation method based on combat behavior tree in this embodiment of the invention are similar to the process and principle of the aforementioned simulation system based on combat behavior tree. Relevant details can be found in the reference, and will not be repeated here.

The communication sections perform communication processing via networks such as the Internet. Drives are also connected to the I / O interface as needed. Removable media, such as disks, optical disks, magneto-optical disks, semiconductor memories, etc., are installed on the drive as needed so that computer programs read from them can be installed into the storage section as required.

In such an embodiment, the computer program can be downloaded and installed from a network via a communication component, and / or installed from a removable medium.

[0071] A fourth embodiment of this application provides a computer-readable storage medium having a computer program stored thereon, which is implemented when executed by a processor:

[0073] Expand the combat behavior model library by extending the combat behavior models through a secondary development library;

[0074] Run the combat behavior model, call the secondary development interface to run the combat behavior tree, or use the executable module to run the combat behavior tree.

The computer-readable medium can be a computer-readable signal medium or a computer-readable storage medium. For example, a computer-readable storage medium can be, but is not limited to, an electrical, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, or device, or any combination thereof.

In this embodiment, the computer-readable storage medium can be any tangible medium containing or storing a program that can be used by or in conjunction with an instruction execution system, apparatus, or device.

[0076] Computer-readable signal media may include data signals propagated in baseband or as part of a carrier wave, carrying computer-readable program code. Such propagated data signals may take various forms, including but not limited to electromagnetic signals, optical signals, or any suitable combination thereof. Computer-readable signal media may also be any computer-readable medium other than computer-readable storage media, which can send, propagate, or transmit programs for use by or in connection with an instruction execution system, apparatus, or device.

[0077] Program code contained on a computer-readable medium may be transmitted using any suitable medium, including but not limited to wireless, wire, optical fiber, RF, etc., or any suitable combination thereof.

In this regard, each block in the flowchart or schematic diagram may represent a module, segment, or portion of code containing one or more executable instructions for implementing the specified logical function. It should also be noted that in some alternative implementations, the functions marked in the blocks may occur in a different order than those shown in the drawings. For example, two consecutively indicated blocks may actually be executed substantially in parallel, and they may sometimes be executed in reverse order, depending on the functions involved. It should also be noted that each block in the schematic diagram and / or flowchart, and combinations of blocks in the schematic diagram and / or flowchart, can be implemented using a dedicated hardware-based system that performs the specified function or operation, or using a combination of dedicated hardware and computer instructions.
