[0032] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings. Here, the exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0033] In the description of this specification, the terms "include", "including", "have", "contain", etc. are all open terms, which mean including but not limited to. The descriptions with reference to the terms "one embodiment", "a specific embodiment", "some embodiments", "for example", etc. mean that the specific features, structures or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. The order of steps involved in each embodiment is used to schematically illustrate the implementation of the present application, and the order of steps is not limited and can be appropriately adjusted as needed.

[0034] First, the terms involved in the embodiments of the present invention are explained.

[0035] Reflective memory network: It is composed of reflective memory cards, optical fibers, and reflective memory network switches. The simulation nodes in the reflective memory network need to be inserted with reflective memory cards, and data interaction is achieved by connecting the reflective memory cards to optical fibers.

[0036] GBB: General Blackboard Technology is an in-memory database mainly used in simulation. It can store all data in the simulation process in memory to improve data access efficiency.

[0037] Distributed simulation: Multiple simulation nodes are interconnected through a network, and joint simulation is participated by one or more simulation platforms.

[0038] The inventor found that during the operation of the simulation system in the distributed simulation, a large amount of simulation data will be generated. These simulation data have the characteristics of large data volume, complex data structure, and high data real-time requirements, and need to meet the simulation system's demand for rapid reading and writing of simulation data. Generally, in order to ensure the consistency of the simulation data, a data reading and writing mutually exclusive mode is adopted, that is, at the same time, only the reading or writing of simulation data is allowed, and this mode will cause the reading and writing efficiency of data to be reduced. Therefore, the embodiment of the present invention proposes to adopt a general blackboard technology, by double buffering the data in the memory, when the simulation is running, one copy of the data is only used for reading, and the other copy of the data is only used for writing, and the next simulation cycle, the uses of the two copies of the data are interchanged, and the mode of exchanging this memory space for time is adopted to improve the reading and writing efficiency of data.

[0039] In addition, in a distributed simulation environment, simulation data between simulation nodes needs to be shared to ensure consistency, and a large amount of simulation data needs to be exchanged between simulation nodes. Existing distributed simulation communication methods mainly include HLA, DDS, RPC, MQ and other methods, all of which use TCP / IP as the communication protocol. When the number of simulation nodes is large and the amount of data is large, it is impossible to meet the high real-time transmission requirements of simulation data. The embodiment of the present invention proposes to use a method based on a reflective memory network to realize the interaction between simulation nodes. Compared with the traditional method of using Ethernet interconnection, it has the advantages of small interaction delay, large data transmission throughput, and data transmission does not occupy CPU resources, and can achieve ns-level data transmission delay.

[0040] Figure 1 FIG. 1 is a schematic diagram of an interactive system for distributed simulation data in an embodiment of the present invention. Figure 1 As shown, the system includes: a plurality of simulation nodes 10, and each simulation node deploys a reflective memory network environment 101, a simulation system 102 and a GBB data management system 103, and the reflective memory network environment includes a reflective memory network card;

[0041] The simulation system 102 is used to: after performing simulation and obtaining simulation data, write the simulation data into the GBB data management system; and read the simulation data from the GBB data management system according to data requirements;

[0042] The GBB data management system 103 is used to: write the changed simulation data into the reflective memory card in each simulation cycle; after writing is completed, send an interrupt message to the reflective memory card; after receiving the notification message, read the changed simulation data from the reflective memory card and store it in the GBB data management system;

[0043] The reflective memory card 101 is used to: after receiving an interrupt message from the GBB data management system, send the interrupt message and the changed simulation data to the reflective memory cards of other simulation nodes; after receiving an interrupt message sent by other simulation nodes, send a notification message to the GBB data management system of the simulation node where the reflective memory card is located.

[0044] In one embodiment, the system further comprises a reflective memory network switch;

[0045] The reflective memory card is connected to the simulation node through the PCI serial port and the driver is installed;

[0046] The simulation nodes and the reflective memory network switches are interconnected by optical fibers.

[0047] Figure 21 is a schematic diagram of a reflective memory network environment in an embodiment of the present invention. A reflective memory network environment is deployed on each simulation node 1. The models of the reflective memory card and the reflective memory network switch 2 are not limited here.

[0048] In one embodiment, the GBB data management system uses a structure of a main entity table, an entity table, a message table, and a description table to store simulation data;

[0049] The main entity table is used to store basic data of simulation entities in the simulation data, and the basic data of simulation entities includes the number of simulation entities and entity types; for example, the main entity table corresponding to the simulation system 1 includes simulation entity 1, simulation entity 2, and simulation entity 3;

[0050] The entity table is used to store the entity identification, state data and reference relationship of the main entity table of the simulation entity in the simulation data; for example, the entity table 1 of the simulation system 1 stores the detailed data of the simulation entity 1;

[0051] The message table is used to store the interaction messages between simulation systems in the simulation data;

[0052] The description table is used to store detailed data of each data structure of each simulation entity in the simulation data, wherein one data structure corresponds to one description table. For example, simulation entity 1 includes maneuvering data, which includes information such as speed, heading, and position, and the maneuvering data is stored in the description table.

[0053] In one embodiment, the GBB data management system encapsulates a simulation data read access interface and a simulation data write access interface;

[0054] The simulation system writes the simulation data into the GBB data management system through the simulation data write access interface;

[0055] The simulation system reads simulation data from the GBB data management system through a simulation data read access interface.

[0056] Through interface encapsulation, the underlying implementation details of the GBB data management system, such as the relationship between the main entity table and entity table, are shielded, so that developers can access business data without having to learn and master the GBB data management system, reducing learning and development costs and improving development efficiency. The simulation data read access interface and the simulation data write access interface are public interfaces for simulation data. The simulation system, etc., can realize real-time reading and writing of simulation data by calling the above simulation data read access interface and simulation data write access interface, so as to achieve the purpose of sharing simulation data between different processes and systems deployed on the simulation node. Figure 3The following is a schematic diagram of the simulation data sharing principle of the GBB data management system in the embodiment of the present invention. In addition to the simulation system, other systems such as the acquisition and playback system and the data display system can access the above simulation data public interface. The GBB data management system integrates data access, data storage, data management, memory management and data monitoring functions, and also has memory.

[0057] In one embodiment, the GBB data management system is specifically used for:

[0058] In each simulation cycle, the simulation data of the simulation system of the simulation node where the GBB data management system is located is written into the corresponding data area of ​​the simulation node in the reflective memory card;

[0059] After writing is completed, an interrupt message is sent to the reflective memory card;

[0060] After receiving the notification message, according to the simulation node identifier in the notification message, the simulation data is read from the corresponding data area of ​​the simulation node corresponding to the simulation node identifier in the reflective memory card and written into the GBB data management system.

[0061] Figure 4 The schematic diagram of the reflective memory card area division in the embodiment of the present invention. In a distributed simulation environment, the simulation systems running on different simulation nodes may be different, or the simulation entities running are different. For example, the red party entity model is executed on simulation node A, and the blue party entity model is executed on simulation node B. In order to ensure the synchronization and consistency of simulation data between different nodes, it is required that the simulation data can be exchanged between simulation nodes, and the real-time performance of data interaction needs to meet the simulation requirements. Therefore, the present invention adopts data communication technology based on reflective memory network to solve the data interaction between simulation nodes.

[0062] First, the data area of ​​the reflective memory card is divided according to the number of simulation nodes in the reflective memory network environment. For example, if the size of the reflective memory card is 256MB and there are N nodes in total, it is divided into N sub-areas, and the size of each sub-area is 256 / N (MB); then the mapping relationship between the simulation node identifier and the sub-area is established, and each simulation node writes the simulation data that needs to be interacted to the corresponding sub-area, see Figure 4 .

[0063] Figure 5The schematic diagram of simulation data interaction based on the reflective memory card in the embodiment of the present invention. After the GBB data management system of the simulation node finishes writing the simulation data, the reflective memory card sends an interrupt message and the changed simulation data to other simulation nodes, and the interrupt message carries the simulation node identifier; after receiving the interrupt message, the reflective memory card of the other simulation node sends a notification message to the GBB data management system of the simulation node where the reflective memory card is located, and the notification message carries the simulation node identifier. After receiving the notification message, the GBB data management system reads the simulation data from the reflective memory card according to the simulation node identifier.

[0064] In order to realize the transmission of data objects, the data that needs to be interacted during the simulation operation is structured and defined. In one embodiment, the simulation data is read and written using a predefined data structure. For example, entity attributes are defined as EntityInfo, entity location information is defined as GeoPosStruct, etc., and the defined data structure is used as the simulation data interaction standard, requiring the simulation system to read and write according to the defined data structure. At the same time, in order to meet the expansion needs of the simulation system, data expansion is supported.

[0065] In one embodiment, the GBB data management system is specifically used for:

[0066] When the changed simulation data is written into the corresponding data area of ​​the simulation node in the reflective memory card, the address of the corresponding data area is queried according to the simulation node identifier of the simulation node;

[0067] Calculate the writing position of the simulation data in the address according to the data type in the interrupt message;

[0068] The dummy data is written at the write location.

[0069] The following will combine the specific simulation system to explain in more detail the process of distributed simulation data interaction based on GBB and reflective memory network environment, so as to provide support for distributed simulation. The distributed simulation process based on GBB and reflective memory network environment is as follows:

[0070] 1. Build a reflective memory network environment. Here, it is assumed that the reflective memory card has been installed, the optical fiber has been connected, and the driver has been installed. Use the reflective memory card management tool to query the nodeid of the reflective memory card as the simulation node identifier, recorded as ID (equivalent to the IP address configured by the network card). Here, it is assumed that there are two simulation nodes participating in the simulation. The ID of simulation node A is 0x1, and the ID of simulation node B is 0x2.

[0071] 2. Based on the provided development kit, including the defined data structure and interface, a simulation system is developed. The SSG simulation system is deployed on simulation node A to run the first entity model; and the VBS simulation system is deployed on simulation node B to run the second entity model;

[0072] 3. SSG simulation system on simulation node A and VBS simulation system on simulation node B;

[0073] 4. During the simulation operation, the SSG simulation system and the VBS simulation system respectively call the simulation data write access interface to write the simulation data to the GBB data management system, and at the same time need to read the simulation data of the other party from the GBB data management system. For the GBB data management system, the status data of all entities in the two simulation systems are stored at the same time;

[0074] 5. In each simulation cycle, the GBB data management system will write the changed simulation data into the reflective memory card, specifically the data area corresponding to the simulation node. Here, it is assumed that the simulation system on the simulation node A needs to write the status data of two simulation entities to the reflective memory card in one simulation cycle. Then, the address of the reflective memory card is queried according to the ID (0x1) of the simulation node A. Assuming that the address is 0x00000000 to 0x00000FFF, the size of the entity status data is 32 bytes, and the write address of the entity status data is calculated according to the data type (here it is assumed to be 0x0000001F). Starting from the address 0x0000001F, first write an integer 2 (4 bytes) to indicate that there are 2 entity status data behind, and then write the specific status data of 2×32=64 bytes in total;

[0075] 6. After completing the simulation data writing work of a simulation cycle, the reflective memory card sends an interrupt message, in which the simulation node ID and data type are sent as parameters to other simulation nodes;

[0076] 7. When the reflective memory card of the simulation node B receives the interrupt message, it parses the ID (0x1) and data type of the simulation node in the interrupt message, calculates the sub-area of ​​the simulation node according to the ID as 0x00000000, and calculates the starting position of the simulation data writing according to the data type as 0x0000001F, and then reads 4 bytes as an integer (2) according to the convention, and then reads 2 32-byte data, and converts the data into StatusInfo format;

[0077] 8. Write the simulation data in the reflective memory card into the GBB data management system. When the VBS simulation system reads data from GBB again, it will read the updated data.

[0078] 9. After the above steps, the interaction of simulation data between the simulation systems in the two simulation nodes is completed.

[0079] The embodiment of the present invention further proposes a distributed simulation data interaction method, which is applied to a simulation system. The principle of the method is similar to that of the distributed simulation data interaction system, and will not be described in detail here.

[0087] Step 703: after receiving the notification message, read the changed simulation data from the reflective memory card and store it in the GBB data management system.

[0088] The embodiment of the present invention further proposes another distributed simulation data interaction method, which is applied to a reflective memory card.
