DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] The purpose of the present invention is to provide a distributed simulation system that integrates equipment task components, to support the development of equipment task components under various mode tasks for a distributed simulation system that synthesizes virtual and real elements, and to provide an integrated design, thereby achieving the purpose of streamlining the system framework scale, improving code reuse rate, and simplifying the system usage process.

[0018] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1 As shown, the present invention provides a distributed simulation system integrating equipment task components, including an equipment task setting subsystem and an equipment entity data model; during simulation, the equipment task setting subsystem drives the equipment entity data model to run according to the received simulation task information to obtain the simulation result.

[0020] like Figure 2As shown, the equipment task setting subsystem includes a task component operation branch determination module (not shown in the figure), a simulation task module, an equipment drive task module, an equipment entity task module and an equipment component task module; wherein the simulation task module, the equipment drive task module, the equipment entity task module and the equipment component task module successively implement the front-end input of digital simulation or digital-physical combined simulation, the equipment digital model operation drive data input, the equipment digital model operation solution data input and the engineering-level simulation control information input, branch operation, and converge at the equipment simulation model operation part.

[0021] In a specific application example, based on the general operating platform for distributed simulation supporting combat level and engineering level, and relying on the model template development framework, a "hierarchical, common bottom layer, multi-branch" task component design and development mechanism is formed under a unified software architecture to complete the task component structure design, task component interface design and task component operation branch design. It can connect the task data information generated by full digital, simulator and actual equipment in different modes of simulation tests such as engineering-level simulation, large-sample statistical simulation, man-in-the-loop simulation and online training simulation of actual soldiers and equipment, drive the operation of the shared equipment entity data model, and output the model solution process and results to the simulation platform data bus.

[0022] The specific contents are as follows: the simulation task information includes a task information source and task information; the task information includes at least one task driving event.

[0023] (1) The task component operation branch determination module is used to: determine a simulation mode according to the task information source; the simulation mode includes a plurality of operation branches corresponding to the task information, thereby determining the content and flow of the equipment digital model operation information release.

[0024] In the task component operation branch determination module, when the task information source is a real-equipment guided task information source, the corresponding simulation mode is a real-soldier real-equipment online training simulation mode; when the task information source is a simulator / software simulation task information source, the corresponding simulation mode is a human-in-the-loop simulation mode; when the task information source is a simulation platform-generated task information source, the corresponding simulation mode is a large sample statistical simulation mode or an equipment engineering-level simulation mode.

[0025] (2) The simulation task module is used to: receive the task information and the simulation mode, and construct a simulation drive logic flow according to the task information and the simulation mode. Determine an operation branch identifier according to the simulation drive logic flow, and the operation branch identifier is used to indicate the order or position of subsequent equipment drivers in the overall simulation task.

[0026] The simulation task module can realize the front-end input of a certain equipment model participating in digital simulation or digital-physical combined simulation. It has a high degree of coupling correlation with the adopted simulation platform. It subscribes to the task-driven events on the simulation platform data bus according to the data type of the task component interface, and loads dependent files or calls related information service interfaces for subsequent task execution according to the initial simulation configuration information.

[0027] (3) The equipment driving task module is used to determine the corresponding equipment binding data package based on the simulation driving logic process and the task information source. The equipment driving task module needs to receive equipment binding data packages from different sources without distinction, including data sources such as actual installation connection, simulator / software, and simulation platform generation.

[0028] In the equipment driving task module, when the task information source is the actual installation and docking task information source, since the binding data package of the actual installation and docking is the most comprehensive, the corresponding equipment binding data package is determined in the following ways: obtaining it through the middleware software in an online integrated manner, and directly parsing and driving the equipment digital model to run; wherein, the middleware software includes DDS middleware, HLA middleware and TENA middleware.

[0029] When the task information source is a simulator / software simulation task information source, since the binding data packet generated by the simulation has the driving information of the equipment digital model operation, but lacks the TSPI information related to the parent node platform, it needs to be supplemented through the simulation data bus. The corresponding equipment binding data packet is determined in the following ways: obtaining through middleware software in an online integrated manner; wherein the middleware software includes DDS middleware, HLA middleware and TENA middleware.

[0030] When the task information source is a task information source generated by a simulation platform, since the amount of information in the binding data packet generated by the simulation platform is small and sometimes even insufficient to support the operation of the equipment digital model, the corresponding equipment binding data packet is determined in the following ways: obtaining the binding parameters by solving the binding parameters in a synchronous integrated binding settlement model, and importing the complete binding data packet through a preset parameter file using an offline intermediate interface integration method. The format types of the preset parameter file include XML, txt, dat and Excel.

[0031] (4) The equipment entity task module is used to: identify and parse the equipment binding data packet to obtain equipment driving information; drive the equipment entity data model to run based on the simulation driving logic process and the equipment driving information to obtain simulation results; and generate equipment component control instructions based on the equipment driving information.

[0032] Specifically, the equipment entity task module is a task component related to the operation and solution of the equipment digital model. It is used to identify and parse equipment binding data packets under different mode applications. At the same time, it needs to identify the information source. It is the convergence point of different branch directions from different task sources.

[0033] (5) The equipment component task module is used to: call the corresponding equipment component to execute the corresponding digital simulation according to the equipment component control instruction; and record the operating status of each equipment component participating in the digital simulation.

[0034] Specifically, the equipment component task module is an extension module that supports the equipment engineering-level simulation mode. It needs to receive control instructions for equipment digital model solution issued by the equipment entity task module through the simulation data bus and feedback operation process / status information to achieve more fine-grained equipment mechanism simulation. In most cases, it is related to the hardware operating environment / system and generally runs slowly.

[0035] The equipment entity task module is also used to determine the execution status of the simulation drive event according to the operation status of multiple equipment components.

[0036] The equipment driving task module is also used to determine the simulation task status according to the execution status of multiple simulation driving events, and send the simulation task status to the simulation task module for display.

[0037] (6) The task component interface setting module is used to set the component interface according to the simulation drive logic flow and the equipment drive information to form a plurality of connected operation branches corresponding to the simulation task information. In other words, the task component interface design of the equipment model mainly includes a task identification part and an equipment drive information identification part. Table 1 below is an interface definition information table constructed in an example.

[0039] In summary, the present invention focuses on the needs of various application modes such as engineering-level simulation, large-sample statistical simulation, human-in-the-loop simulation, and online training simulation of real soldiers and equipment. Under a unified software architecture, the task model component framework and operation process are designed according to the idea of ​​"hierarchical, common bottom layer, and multiple branches". First, the task component is divided into simulation task module, equipment drive task module, equipment entity task module, equipment component task module and other levels, and then the component interface design is completed according to the task identification and equipment drive information, and finally multiple operation branches corresponding to the simulation task are formed. The present invention can share the running part of the equipment simulation model, and the technicians who improve the code reuse rate and simplify the system use process ensure that the simulation task component is simple and easy to use.

[0040] In a specific practical application, the equipment digital simulation test is used as the specific implementation verification load, design task components, operation processes and logic, such as Figure 2 and Figure 3 As shown, the specific steps are as follows: (1) With the general simulation platform model template framework as the underlying support, the task component program architecture is constructed, which mainly includes the initialization part, the time and rule-based task triggering part, the task parsing and execution part, the configuration interface part, and the simulation process or simulation result display interface part.

[0041] (2) Development of the task component configuration interface. The model view is designed based on the principle of hierarchical multi-branch. The attack and defense confrontation training simulation, deduction simulation, statistical simulation, and signal-level simulation are completed in a "check-box" manner. The execution branches are mutually exclusive. The configuration file type (.ini or .xml), content format, and default loading path are designed.

[0042] This step is to design the running branch in the task component running branch determination module. The designed running branch can be used as a guide for data call and flow in the subsequent actual simulation process. Figure 2 For example, "Engagement Level Simulation", "Man in the Loop", and "Installation in the Loop" are all "checked" in this step. In subsequent applications, it will be determined whether it is an engagement level simulation. If not, the task source set in the running branch will be called and the corresponding processing will be performed; if so, it will be determined whether there is a man in the loop.

[0043] (3) Design and development of simulation task modules, design of task initialization interface, including configuration ports such as simulation time, number of simulations, engine time ratio and number of entities, and design of publish / subscribe data topics and event topics related to associated equipment model entities.

[0044] in, Figure 2 The "Start Task Trigger", "Iterations", and "Task End" are all set in this step; Figure 3 The "start", "number of launches", and "end" in are also completed in this step. Specifically, the equipment task data packet is received and parsed through the simulation task module to obtain the task information source and task information, and then the simulation mode is determined, thereby providing the basic task information required for the completion of the operation branch.

[0045] (4) Design and development of equipment-driven task modules. Design the task-driven interface content according to the operation requirements of the digital model and refer to the actual interface protocol, including the physical model initialization and segmented execution operation support part; design the middleware interconnection API interface that connects to the actual installation or simulator / software. The middleware is implemented in the form of UDP communication (configure the network address and port as the unique identifier); design the task parsing and processing functional module.

[0046] in, Figure 2 "Analysis of platform generated task information source", "Analysis of simulation task information source" and "Analysis of actual installation and connection task information source" are implemented in this step.

[0047] (5) Design and development of equipment entity task module. Design the equipment entity model loop execution module, mainly designing the publish-subscribe data topics related to task execution through the simulation platform data bus.

[0048] in, Figure 2 The "calling equipment physical task module" and "calling equipment digital module" are both implemented in this step. When executing the above modules, the actual simulation drive process can be obtained according to the simulation drive logic process and equipment drive information, such as Figure 3 shown.

[0049] Figure 3 In the process, determine whether it is the weapon control mode; if it is the weapon control mode, receive various metadata, receive the launch order, and determine whether the launch conditions are met; if the launch conditions are not met, cancel the launch; if the launch conditions are met, determine whether it is the actual weapon control mode; if it is not the actual weapon control mode, bind the simulated weapon control parameters, launch the weapon, and call the engagement level model to control the weapon maneuver; if it is the actual weapon control mode, bind the actual weapon control parameters, launch the weapon, and call the engagement level model to control the weapon maneuver; if it is not the weapon control mode, read the interface parameters to determine whether the entity is equipped with weapons; if the entity is not equipped with weapons, cancel the launch; if the entity is equipped with weapons, determine whether it is the signal level mode; if it is the signal level mode, bind the signal level mode metadata, launch the weapon, call the signal level model to control the weapon maneuver, and determine whether the number of launches has been completed; if it is not the signal level mode, bind the large sample mode metadata, launch the weapon, call the engagement level model to control the weapon maneuver, and determine whether the number of launches has been completed; if the number of launches has not been completed, return to the step of determining whether it is the signal level mode; if the number of launches has been completed, end.

[0050] (6) Design and development of equipment component task modules, design of extended functions associated with the operation of equipment entity task modules, including signal-level simulation control instructions (equipment and facility control instructions, target machine control instructions, operation instructions, etc.), status feedback information (object status, target machine status, environmental status, simulator / equipment and facility signal input, etc.); design of signal-level simulation configuration interface and supporting file loading path; design of seeker signal-level simulation data interaction format.

[0051] when Figure 2 When executing "calling equipment entity task module" and "calling equipment digital module", more specific and precise control can be achieved through the equipment entity's control over its internal components.

[0052] (7) Data recording function module design: Four types of task information source recording function modules are designed accordingly. The interactive data topics are associated with the four simulation modes and the recording cycle can be set.

[0053] (8) Complete the packaging and integration of task components, assemble them together with the equipment entity data model into an equipment distributed simulation system, and load them into the simulation platform to support various types of simulation tests.
