The war form is changing from a single domain to multi-domain coordination. The combat confrontation space breaks through the three-dimensional geographical space, forming a joint feature of multiple domains such as land, sea, air, space, electricity, network, and cognitive fields. It plays a vital role and significance in threat reconnaissance, organizational confrontation, command and control, and coordinated cooperation in multi-domain joint confrontation.

[0003] Traditional simulation systems often focus on a single field or simple virtual environment construction, and it is difficult to truly and comprehensively simulate complex confrontation scenarios of multi-domain integration. In addition, there are many deficiencies in virtual-real interaction, real-time mapping, and system scalability and flexibility, and they cannot meet the requirements of efficient and accurate support for different types of confrontation tests. At the same time, in the research and development and testing of related equipment, they often face problems such as high field test costs and difficulty in effectively conducting equipment effectiveness verification in confrontation environments. There are shortcomings such as low test efficiency, long cycles, high costs, inconsistent technologies, high interaction difficulties, insufficient tests, and unsatisfactory verification results.

[0004] Therefore, how to meet the needs of complex multi-domain confrontation test environments for internal and external linkage, efficient interaction between virtual and real resources, and real-time scheduling is an issue that technical personnel in this field urgently need to solve.

[0064] 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.

[0065] like Figure 1 As shown, the embodiment of the present invention discloses a multi-domain integrated confrontation test environment virtual-real mapping parallel simulation system, including: an infrastructure layer, a data resource layer, an operation support layer and a system application layer;

[0066] The infrastructure layer is used to connect to various physical devices, platforms and systems that actually participate in the confrontation test in multiple physical domains, collect real physical data resources of multiple heterogeneous systems, perform preprocessing, and transmit the preprocessed real physical data resources to the data resource layer in real time;

[0067] The data resource layer is used to store and manage the received heterogeneous data resources;

[0068] The operation support layer includes a heterogeneous resource interface gateway, a data service bus and five basic service modules; the heterogeneous resource interface gateway is used to realize the interconnection and interoperability between various heterogeneous data resources; the data service bus is used as a communication middleware to realize the real-time distribution and resource sharing of various heterogeneous data resources; the five basic service modules are used to realize simulation service, situation service, evaluation service, proxy service and time system service respectively;

[0069] The system application layer includes a set of tools for realizing test environment modeling, scenario simulation and deduction, confrontation scenario situation display and test data evaluation.

[0070] The present invention establishes a proxy model of the corresponding component of the actual or semi-physical simulation system in the virtual simulation test system. Through the proxy model, the interaction between the component model and other components or simulation engines remains unchanged, while the business logic of the component model is solved by the actual system or semi-physical simulation system, that is, the mapping relationship between the combat events in the virtual confrontation space and the test resources in the real space is completed, and the efficient interaction and real-time scheduling between virtual and real resources are realized, and parallel scenes in a multi-domain integrated confrontation environment are created, so that trainees can get highly simulated training close to actual combat. Figure 2 shown.

[0071] Below, each layer of the system of the present invention is further described.

[0072] 1. Infrastructure layer: The infrastructure layer provides the software and hardware basic support environment and network support platform for the system of the present invention, covering various physical equipment, platforms and systems actually involved in the confrontation test, such as real weapons and equipment, communication equipment, sensors, etc., distributed in multiple physical fields such as sea, land, air, space, electricity, and network, responsible for collecting real physical data, and transmitting the data to the data acquisition module and data preprocessing module through the sensor interface. The data acquisition and preprocessing modules perform preprocessing operations such as cleaning, filtering, format conversion, etc. on the acquired raw data, extract key information, and transmit the processed data to the data resource layer in real time.

[0073] 2. Data resource layer:

[0074] The data resource layer stores and manages the resource data of multiple domains such as sea, land, air, space, electricity, and network required by the system of the present invention, including model data, simulation data, test data, equipment data and other resources under real soldiers and equipment systems, semi-physical simulation systems, virtual simulation systems and non-standard application systems. Among them, the model data defines the object models between different systems to realize the interaction between heterogeneous systems; the data resource management of the data resource layer covers database unification, data structure unification, distributed storage and call, and provides underlying data support for the virtual-to-real mapping parallel simulation system of the multi-domain integrated confrontation experimental environment.

[0075] 3. Operation support layer:

[0076] The operation support layer includes a heterogeneous resource interface gateway, a data service bus and five basic service modules.

[0077] (1) The data resource layer and the operation support layer realize the unified integration of data resources and the operation support platform through standardized access and control interfaces and gateways.

[0078] On the basis of having the conditions for virtual-real resource mapping in business logic, it is necessary to solve the problem of interconnection and integration between the virtual simulation test system and the real installation and semi-physical simulation system. The method of interconnection and integration between heterogeneous resources is to develop a heterogeneous resource interface gateway as a bridging tool between heterogeneous resources. By realizing the mapping of software interfaces and communication protocols between systems, it provides support for the interconnection, intercommunication and interoperability between heterogeneous resources. The functional composition of the interface gateway is as follows: Figure 3 shown.

[0079] The heterogeneous resource interface gateway includes: a scenario loading module, a publication and subscription management module, a heterogeneous system interface conversion module, a communication protocol conversion module, a data transceiver module, a data acquisition module and a time synchronization client module.

[0080] The scenario loading module is used to load simulation scenario data from the database or local files and initialize the local virtual simulation test system.

[0081] The publication and subscription management module is used to complete the establishment and cancellation of publication and subscription relationships, so that the communication middleware can send and receive data on demand, and when there is no need to send or subscribe to related data, the corresponding publication and subscription relationship is cancelled.

[0082] The heterogeneous system interface conversion module is used to realize the interactive data mapping between the local virtual simulation and testing system and the heterogeneous system, converting the data generated in other systems (such as entity attributes, location data, motion characteristics, combat information, etc.) into the format required by the virtual simulation and testing system, and at the same time receiving the return instructions of the heterogeneous system and passing them to the virtual simulation and testing system.

[0083] The communication protocol conversion module is used to realize the communication protocol conversion between the virtual simulation test system and the heterogeneous system, so that the information can be communicated according to the publishing / subscription, message communication and other modes agreed upon by the virtual simulation test system.

[0084] The data transceiver module is used to send or receive data published or subscribed through the communication middleware, respond to and execute simulation control instructions, including: simulation control instructions, such as simulation initialization, operation, pause, continue, stop and other functions.

[0085] The data acquisition module is used to merge all data or the data required in this test configuration by calling a unified data recording interface, store them in a local database, and summarize the test data after the test to form a complete test collection database.

[0086] The time synchronization client module is used to achieve the time unification between heterogeneous systems and virtual simulation test systems, ensuring the coordinated advancement of the astronomical time, operational time and test environment of the entire system. Through the time synchronization client module, time information is obtained from the clock source, the time synchronization function of each node is completed, and the time synchronization between this node and other nodes is ensured.

[0087] (2) The data service bus adopts real-time distributed DDS communication middleware based on data center architecture, supports topic publishing and subscription and dynamic publishing and subscription, and supports QoS strategy.

[0088] To meet the requirements of real-time, reliability and robustness in application fields such as distributed joint training systems. The present invention relates to distributed general real-time communication middleware technology, providing real-time distributed DDS communication middleware based on data center architecture, adopting a centerless discovery mode, supporting topic publication and subscription and dynamic publication and subscription methods, and supporting QoS strategies such as reliability, persistence, and multicast. It can interconnect with other standard-compliant middleware to complete seamless connection between distributed heterogeneous training resources such as real-installation systems, construction simulation systems, and virtual simulation systems, solve the interconnection and interoperability problems between various test nodes, and realize efficient and real-time distribution and resource sharing of multi-source heterogeneous multi-domain data. The data bus provides two modes of direct connection and gateway access. The communication middleware of the present invention can solve the following technical problems:

[0089] 1) Efficient and flexible data transmission: Based on the data center architecture, an efficient data distribution mechanism is implemented to publish and subscribe data. Different data can be transmitted in different forms and protocols, which facilitates users to make different choices based on the data transmission size, frequency, and reliability, ensuring the real-time data transmission during training.

[0090] 2) Dynamic quality control QoS: Provide quality control strategies at the application layer to balance the stability and efficiency of system operation to the greatest extent when conducting simulation interactions with large amounts of data;

[0091] 3) Compatibility with multiple distributed systems: Provide a set of mechanisms and frameworks that support different underlying implementations, and be compatible with distributed technology systems such as HLA, TENA, and DDS;

[0092] 4) Flexible switching of transmission modes: Use different data transmission channels (such as RTPS, multicast, TCP, UDP, reflective memory network, etc.) according to actual needs, and flexibly switch between different channels, supporting cross-LAN remote interconnection and WAN interconnection;

[0093] 5) Fast system access: Provides visual interface modeling tools and code generation tools that can quickly generate various system interconnection code frameworks, and uses the same API in different operating environments to provide the system with the ability to quickly access the training network;

[0094] 6) Unified development environment: It can unify different technical implementations at the development level, shield the differences in underlying technical details as much as possible, and reduce the difficulty of distributed system development.

[0095] (3) Five basic service modules:

[0096] The five basic service modules are: simulation service module, situation service module, assessment service module, agent service module and time system service module;

[0097] 1) The simulation service module is used to provide simulation services based on the combination of discrete time and continuous time. In the simulation service based on discrete time, time is regarded as discrete points, and only the changes in the state of the virtual simulation test system at discrete time points are recorded. For example, if the time acceleration ratio is set to X, the system state changes are displayed at intervals of X seconds; in the simulation service based on continuous time, time is regarded as an uninterrupted and smooth flow process, and the changes in the state of the virtual simulation test system at any time are recorded; the combination of the two modes can simulate the entire complex simulation system more accurately, drive model resources for simulation calculations, and complete the integrated verification of typical military intelligent confrontation system scenarios.

[0098] 2) The situation service module is used to provide situation data fusion, processing and publishing services;

[0099] 3) The evaluation service module is used to provide the construction of an evaluation indicator system based on a flowchart and provide data collection, processing and analysis capabilities;

[0100] 4) The proxy service module is used to connect and coordinate simulation entity components (real soldier L, constructor V, virtual C) in different physical domains. By completing the communication protocol and data format conversion between heterogeneous systems, the data between different systems is converted into a unified or mutually recognizable format, and the information exchange and data analysis between data resources and communication middleware in different physical domains are completed. The multi-domain resources such as real, simulated, and virtual in the LVC system are accessed to the test system, and the interconnection and interoperability with other nodes are realized, so as to improve the authenticity and practicality of the simulation. The specific functions that can be realized include:

[0101] A) Complete information exchange and data parsing between LVC resources and DDS communication middleware.

[0102] B) Complete the time advancement and synchronization of this node;

[0103] C) Perform local simulation management and control on LVC resources participating in the experiment.

[0104] The specific workflow of the proxy service module is as follows:

[0105] a) Request reception. Entities from different domains, such as real soldiers L, constructors V, and virtual C, send requests to the proxy through the network. These requests include information from other domains, request for coordinated action instructions, etc. For example, in a military confrontation simulation, a real soldier unit in a real soldier system requests the location information of a virtual aircraft model in order to adjust its own action strategy.

[0106] b) Identity verification and permission check: The proxy service module verifies the entity information sent by the request to ensure that the request source is a legitimate and authorized entity; at the same time, it checks whether the entity has sufficient permissions to obtain resources and perform the requested operation.

[0107] c) Request parsing and conversion. Parse the request to determine the type and purpose of the request. Since entities in different domains may use different communication protocols, data formats, and expressions, the proxy service module needs to convert the request into a format that the target domain can understand. For example, the real soldier domain uses a command format based on military communication standards, while the virtual model uses a specific message format inside the software. The proxy service needs to convert the real soldier command into a message that the virtual model can receive.

[0108] d) Targeting and resource searching. Based on the request, the proxy service determines the target domain or target resource to be accessed, which involves searching for the corresponding resource in a distributed multi-domain database, model library or server cluster.

[0109] e) Data acquisition and processing. Obtain the requested data and services from the target domain. During the acquisition process, it is necessary to interact with the server and model of the target domain and obtain resources according to the rules and interfaces of the target domain. After acquiring the data, the proxy service pre-processes the acquired data, such as data cleaning and format unification.

[0110] f) Response conversion and return. Convert the processed response data into a format that the requesting entity can understand, and then return it to the requesting entity through the network. Ensure that the content of the response is complete, accurate and meets the receiving requirements of the requesting entity.

[0111] g) Logging and monitoring. The proxy service module will record relevant information of the entire request-response process, including the source of the request, the content of the request, the corresponding content, processing time, etc. These logs can be used for subsequent system monitoring, troubleshooting and performance evaluation; at the same time, through real-time monitoring of the proxy service, abnormal requests, service overload and other problems can be discovered in a timely manner.

[0112] 5) The time synchronization service module is used to provide distributed system time unification tools and mechanisms in a distributed environment, and coordinate the system time synchronization among distributed test nodes.

[0113] In a distributed environment, the time of various test resources is autonomous, the message transmission between systems is asynchronous, and time management is mainly used to provide time unification function during system operation. The time service module of the present invention provides distributed system time unification tools and mechanisms to coordinate system time synchronization between distributed test nodes. It provides time calibration services that comply with the NTP-V4.0 protocol standard or achieves time consistency through GPS / Beidou clock access.

[0114] The detailed simulation test timing technology mainly includes:

[0115] A) Network soft synchronization method uses the network time protocol (such as NTP) to synchronize each semi-physical device to a standard time source (such as a server). Each client divides the local time signal into synchronization signals of different frequencies through a frequency division algorithm to meet the requirements of heterogeneous systems for different time granularities.

[0116] B) Network hard synchronization method, each node is connected to the Beidou (GPS) time system equipment, and the standard pulse signal is divided into synchronization signals of different frequencies through hardware to meet the requirements of heterogeneous systems for different time granularities.

[0117] C) A time synchronization method combining software and hardware. The time server is connected to the Beidou (GPS) time system equipment and broadcasts the standard time through the hardware interface (serial port). Each client divides the standard second pulse signal into synchronization signals of different frequencies through a frequency division algorithm to meet the requirements of heterogeneous systems for different time granularities.

[0118] 4. The system application layer includes a complete set of application tools to support test verification, including interface adaptation tools, simulation control tools, situation display tools and analysis and evaluation tools. The functions of each tool are further explained below:

[0119] 1) The interface adaptation tool adopts a unified modeling language and combines the characteristics of the simulation test task to build the test environment through interactive format modeling, interactive relationship modeling and protocol mapping relationship modeling. The modeling result generates an interface code framework through the code generation module, and after development, a complete interface program or protocol mapping gateway is formed. The test system is connected to the test environment through the interface program or gateway during operation.

[0120] 2) As software for controlling and simulating the entire process, the simulation control tool supports the development of corresponding simulation models and physical and semi-physical proxy models, and completes the conversion of test plans and test intentions into electronic and digital assumption files that can be recognized by computers. At the same time, it issues test process control instructions and distributes various types of data to simulate and deduce the assumptions, providing support for the later analysis, research, optimization, and statistics of the plan, and can verify the integration of typical intelligent confrontation system scenarios.

[0121] 3) The situation display tool is based on military and commercial standard geographic information systems to intuitively display the situation of the confrontation scenario (2D or 3D), so that situation analysts and test organizers can control the progress of the situation or switch map viewpoints at any time according to the time or place of concern, and supports real-time situation display and offline data display;

[0122] 4) Analysis and evaluation tools are used based on scientific quantitative analysis theories such as event operations and decision support, and use a variety of advanced business intelligence technologies such as data acquisition and statistical analysis to build a simulation evaluation index system, and provide a unified software framework and extension interface for the development of evaluation method libraries, evaluation model libraries, and evaluation algorithm libraries, establish simulation evaluation method models, and post-evaluation, real-time evaluation, and factor evaluation. Use mathematical methods to conduct statistics and analysis on test data, and then provide support for the evaluation of the performance, effectiveness, and applicability of equipment systems.

[0123] Next, the workflow of the system of the present invention is further described.
