[0001] The invention belongs to the field of simulation technology, and in particular relates to a cross-resolution interaction method for equipment models. Background Art

[0002] Equipment, as an important material basis for national defense and military modernization, is the main battlefield for digital technology practice. Building a digital model of equipment and conducting pre-war practice through combat simulation can achieve equipment effectiveness testing, personnel tactics and tactics training, etc. Through combat simulation experiments, the time of each OODA loop in combat can be effectively shortened, and effective attacks can be launched faster than opponents to win battlefield games. With "digital intelligence" transformation, we can promote "digital intelligence" training and continuously improve the digital intelligence level of training.

[0003] As the core content of the simulation system, the simulation model must establish a model of appropriate granularity for different simulation levels such as campaigns, tasks, engagements, and projects in order to adapt to different simulation scenarios and simulation platforms. The granularity of the entity in the model is closely related to the model resolution. The smaller the granularity, the higher the model resolution. The resolution of the model refers to the minimum granularity of the entity described by the model and the level of detail in the attributes, behaviors, inputs, outputs, etc. of the entity described by the model.

[0004] Simulation models of different granularities usually run on different simulation platforms. Only through cross-resolution interaction of models can the consistency of the same equipment models on different simulation platforms be guaranteed. However, due to the different granularity of model descriptions at different levels, different information generated and required, different model description methods, and different simulation platforms on which the models run, multi-resolution models of the same equipment are difficult to interconnect, which brings challenges to cross-resolution interaction of models.

DETAILED DESCRIPTION

[0014] The equipment model cross-resolution interaction method of the present invention is described in detail below through the accompanying drawings and embodiments.

[0015] Embodiment 1 This embodiment discloses a method for equipment model cross-resolution interaction, wherein the resolution of the equipment model is from low to high. m resolutions, resolution1-resolution m ; Resolution i The model is a low-resolution model with a resolution of i The model with +1 is a high-resolution model, where i=1,2,...,m-1; the low-resolution model and the high-resolution model realize cross-resolution interaction of the model through data interaction.

[0016] In the disclosed embodiments, the data interaction includes instruction information interaction, real-time situation information interaction, and report information interaction; the consistency of models of different resolutions is ensured through instruction information, real-time situation information, and report information; the instruction information includes task instructions, action instructions, and action target instructions; the real-time situation information includes platform longitude, latitude, altitude, speed, and direction information; the report information includes action completion report and task completion report; the task instructions include task start instructions.

[0017] like Figure 1 As shown, the specific implementation plan of the equipment model cross-resolution interaction method includes the low-resolution model sending a task start instruction, an action instruction and an action target instruction to the high-resolution model; the high-resolution model feeds back real-time situation information to the low-resolution model in real time, and sends an action completion report and a task completion report after the action and the task are completed.

[0018] The low-resolution model and the high-resolution model maintain initial state synchronization in different scenes, and the high-resolution model waits to receive the low-resolution model task start instruction. i Low-resolution model and resolution i +1 high-resolution model to achieve interaction as an example, the interaction implementation steps are as follows: 1) Resolution i The low-resolution model is converted to high-resolution i The high-resolution model of +1 sends a task start instruction. After receiving the instruction, the high-resolution model initializes the simulation.

[0019] 2) Resolution i The low-resolution model is converted to high-resolution i +1 high-resolution model sends action instructions and action target instructions, resolution i +1's high-resolution model receives and interprets action instructions and action target instructions, and carries out corresponding actions. Action instructions include maneuvering actions, detection actions, strike actions, etc., and action target instructions include maneuvering positions, detection targets, strike targets, etc.

[0020] 3) Resolution i +1 High-resolution model during operation, real-time resolution i The low-resolution model feeds back the current real-time situation information, with a resolution of i The low-resolution model receives and analyzes the real-time situation information, and then displays it after situation synchronization. The real-time situation information includes the current platform longitude, latitude, altitude, speed, direction and other location information.

[0021] 4) Resolution i +1 high resolution model action completed, stop the action, to the resolution i The low-resolution model sends an action completion report message and waits for the next action instruction.

[0022] 5) Resolution i +1 The high-resolution model in the scene where all model actions are executed, and the resolution i The low-resolution model sends a task completion report message, and the cross-resolution interaction ends. i The low-resolution model is prepared to schedule the high-resolution model of the next task slice for simulation.

[0023] Furthermore, in the embodiment of the present disclosure, taking the red and blue aircraft maneuvering chase scene as an example, the equipment model cross-resolution interactive verification is performed, and the specific implementation process includes: (1) The low-resolution model is an aircraft with air maneuverability and is not restricted by actual kinematics. It only sets the target maneuvering position of the aircraft and does not specify the flight path of the aircraft model. The high-resolution model is a six-degree-of-freedom aircraft. The red target aircraft flies in a pre-made curve, and the blue pursuit aircraft dynamically pursues the target aircraft.

[0024] (2) Use the file method for interaction. Different resolution models achieve cross-resolution interaction through file I / O. Specifically, the instruction information, real-time situation information, report information, etc. that need to be interacted are written into different files respectively, and the reading and writing are realized through the processes of two simulation programs of high and low resolution models. The interaction files include task slice instruction files, equipment instruction files, real-time situation synchronization files of each equipment, report files of each equipment, and task slice report files, as listed in the following table. The interaction files are as Figure 2 shown.

[0025] (3) At the start of the task, the low-resolution model sets the command.txt file, and the high-resolution model polls this file at 1s intervals. After detecting the setting, the high-resolution model initializes the simulation and prepares to receive action instructions.

[0026] (4) At the start of the action, Equipment No. 01 starts to act. Taking the maneuver action as an example, the low-resolution model of Equipment No. 01 writes to the command_01.txt file, and the written content includes the instruction code corresponding to the maneuver action and the maneuver target position code. The high-resolution model of Equipment No. 01 polls this file at 0.1s intervals. After detecting the action instruction, it parses the action instruction and the action target instruction and conducts the maneuver action.

[0027] (5) When the high-resolution model starts to maneuver, during the maneuver process, it writes the current platform position information, including platform longitude, latitude, altitude, speed, orientation, etc., to the interaction_01.txt file at 0.1s intervals, as Figure 3 shown. The low-resolution model reads this file at 0.1s intervals and simultaneously obtains the real-time position information. To achieve the consistency of equipment situation information with different resolutions, as Figure 4 shown; the left side is the low-resolution model of the aircraft, and the right side is the high-resolution model.

[0028] (6) At the end of the action, the high-resolution model stops writing to the interaction_01.txt file. Immediately afterwards, the high-resolution model writes the instruction code corresponding to the maneuver action to the report_01.txt file and sends an action completion report. The low-resolution model polls this file at 0.1s intervals. After detecting the instruction, it stops the maneuver.

[0029] (7) At the end of the task, the high-resolution model sets the report.txt file, and the low-resolution model polls this file at 1s intervals. After detecting the setting, the low-resolution model ends this slice task, and this cross-resolution interaction ends.

[0030] The low-resolution model prepares to schedule the high-resolution model of the next task slice to conduct the simulation.
