Description

Technical Field

[0001] The present application belongs to the field of combat simulation technology, and specifically relates to a formal description method and related devices for wireless communication scenarios. Background Art

[0002] With the rapid development of modern military information technology, combat simulation and scenario generation have become key supporting technologies for improving troop training effectiveness and weapon system verification capabilities. The U.S. Army began researching reusable, standardized combat scenarios in 2004 and established the Modular Scenario Description Language (MSDL) research group in 2005. The group is dedicated to standardizing the modeling and expression of scenario content through standardized and structured methods, thereby improving the efficiency of simulation and deduction in complex battlefield environments. my country's GJB 7854-2012 specifies the components of combat simulation scenarios and their description requirements, but does not provide a formal description or the constraint relationship between the elements; GJB 7878-2012 focuses on the general requirements for Army joint tactical training exercise scenario data, proposes four description principles such as targeting, practicality, accuracy, and foresight, and specifies the content and description requirements of exercise scenario data, but the main content is still an unstructured description; GJB 9364-2018 uses XML to specify the data exchange format for electronic countermeasure combat simulation scenarios, but the element content is still in database format. The scenario description method and format often depend on the combat simulation system, with a high degree of coupling and poor reusability and scalability.

[0003] In recent years, some studies have attempted to improve scenario description technology through formal methods. However, traditional formal description methods are mainly aimed at modeling elements of conventional combat scenarios. In the application field of wireless communication scenarios, there are still significant limitations. It is difficult to accurately characterize the relationship between the dynamic electromagnetic environment and complex communication elements, and it is impossible to simulate actual communication equipment in a virtual-realistic manner, which seriously restricts the simulation and verification capabilities of the communication system effectiveness. Summary of the Invention

[0075] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0076] In recent years, some studies have attempted to improve scenario description technology through formal methods. However, current scenario description methods are mainly aimed at modeling elements of conventional combat scenarios. In the application field of wireless communication scenarios, there are still significant limitations: first, there is no formal constraint relationship for communication characteristic parameters such as electromagnetic spectrum resource allocation and channel interference model; second, there is a lack of the ability to describe the spatiotemporal correlation of dynamic time-varying environments (such as mobile node trajectories and multipath effects); third, it cannot effectively support the link quality prediction and anti-interference analysis required for wireless communication effectiveness evaluation, making it impossible for the simulation system to test, evaluate and verify the combat effectiveness of wireless communication scenarios.

[0077] At present, with the increasing networking and intelligence of battlefields, the complexity and dynamics of wireless communication elements in combat scenarios are becoming increasingly prominent: the electromagnetic environment is highly heterogeneous and uncertain, and node mobility causes rapid changes in channel states. Traditional scenario description methods are difficult to accurately characterize these characteristics, which seriously restricts the simulation and verification capabilities of communication system performance.

[0078] In order to solve the above problems, the applicant has developed a new formal description method for wireless communication scenarios, which can simulate actual communication equipment in a virtual and real way, and improve the expression accuracy and cross-platform reusability of wireless communication scenario data.

[0079] Specifically, see Figure 1 , Figure 1 It is a flowchart of an implementation method of a formal description method of a wireless communication scenario of the present application.

[0080] like Figure 1 As shown, the method includes:

[0081] S100: Obtain a wireless communication device configuration table.

[0082] Among them, the wireless communication equipment configuration table includes the model, quantity and parameters of the wireless communication equipment participating in the scenario simulation.

[0083] Specifically, the parameters of the wireless communication device may include operating frequency band, operating type, transmit power, sensitivity, manufacturer, etc.

[0084] Exemplarily, the wireless communication device configuration table may be as follows:

[0085]

[0086] As shown in the configuration table data above, 3 radio stations A and 2 radio stations B participate in the scenario simulation.

[0087] When participating in scenario simulation, wireless communication devices need to connect to the channel simulator and the service generator for semi-physical simulation. They also need to configure the port connection relationship between the wireless communication device and the channel simulator. The parameters of the wireless communication device also include the port of its corresponding channel simulator. For example, "Radio A-1" can be used to identify radio station A bound to port 1 of the channel simulator.

[0088] S200. Based on the combat scenario instruction, a target combat scenario is obtained from a preset combat scenario template library.

[0089] After the wireless communication equipment is configured, the user can select a specific target combat scenario from the template library.

[0090] Among them, the target combat scenario includes the battlefield environment and combat organization grouping. The battlefield environment includes the battlefield area, combat zone and meteorological parameters, etc.; the combat programming grouping includes all basic combat units participating in the scenario simulation, among which the basic combat unit can be a single soldier equipped with weapons, or a vehicle equipped with ammunition, etc.

[0091] Specifically, the combat organization group includes the organization information of the basic combat unit. Each basic combat unit is composed of the elements shown in the following formula:

[0092] E::= <entityname> <entityid> <entityattributes> <entityspace> <entityactlist> <entitytasklist>,

[0093] In the formula, EntityName and EntityId are the name and identification of the basic combat unit, respectively. The identification consists of a string of numbers and is the unique code of the entity. The identification can encode each item in the element content with a number to facilitate storage and retrieval. For example, the first digit of the identification code can use "1" to represent the red team, "2" to represent the blue team, and the second digit can use "1" to represent the infantry.

[0094] EntityAttributes is the basic attribute set of the basic combat unit, including attribute information such as status, relationship, and level; EntitySpace is the spatial attribute of the basic combat unit, which describes the spatial position of the entity, such as the configuration area of each action entity; EntityActList is the action attribute list of the basic combat unit, which represents the behavioral actions that the entity can perform; EntityTaskList is the task list of the basic combat unit, which describes the tasks that the entity must complete according to the combat plan. This attribute loads the task data when the model is instantiated.

[0095] For example, see Figure 2 , Figure 2 This is a schematic diagram of an implementation method of the combat formation of this application. Figure 2 As shown, the combat formation includes two squads, the left wing and the right wing, each squad includes three tanks. For each combat unit, an action command is constructed. For example, the left wing tank 1 moves from the initial position A to the position B along the path L1 from the combat time 00:00:00 to 00:30:00, and at the same time, the right wing tank 4 moves from the initial position C to the position D along the path L2.

[0096] S300. Allocate the wireless communication devices in the wireless communication device configuration table to the basic combat units of the target combat scenario, establish a communication subnet, and obtain a combat scenario communication model.

[0097] After obtaining the target combat scenario and wireless communication equipment configuration table, it is necessary to bind the wireless communication equipment to the basic combat units one by one, establish a mapping relationship, and establish a communication subnet including one or more wireless communication devices to obtain a communication model.

[0098] Specifically, see Figure 3 , Figure 3 yes Figure 1 A flow chart of an implementation method corresponding to S300.

[0099] like Figure 3 As shown, the method for establishing a communication subnet includes:

[0100] S301. Traverse the basic combat units, and each time a target basic combat unit is traversed, determine whether the target basic combat unit has joined the communication subnet.

[0101] First, the basic combat units can be traversed one by one to determine whether they have joined the communication subnet;

[0102] If you have joined, then:

[0103] S302. Continue to traverse the next target basic combat unit.

[0104] If the target basic combat unit has already established a communication subnet, you can skip the target basic combat unit and traverse the next one.

[0105] If not established, then:

[0106] S303: Determine whether the target combat unit has been assigned a wireless communication device.

[0107] If no wireless communication device is assigned:

[0108] S304. Randomly assign a target wireless communication device to the target basic combat unit.

[0109] S305. Traverse the associated basic combat units that have a direct command relationship with the target basic combat unit, and determine whether the associated basic combat unit has been assigned a wireless communication device each time a related basic combat unit is traversed.

[0110] It is understandable that if the target combat unit has been assigned wireless communication equipment, it is possible to directly enter S305.

[0111] If the associated basic combat unit is not assigned wireless communication equipment, then:

[0112] S306. Allocate a wireless communication device of the same model as the target wireless communication device to the associated basic combat unit.

[0113] S307. Continue traversing the next associated basic combat unit.

[0114] If the associated basic combat unit has been assigned wireless communication equipment, then:

[0115] S308: Determine whether the wireless communication device of the associated basic combat unit is consistent with the model of the target wireless communication device, and whether a communication subnet has been established.

[0116] If the wireless communication device of the associated basic combat unit is the same model as the target wireless communication device and a communication subnet has been established, then:

[0117] S309. Add the target basic combat unit to the communication subnet of the associated basic combat unit.

[0118] After the target basic combat unit is added to the communication subnet of the associated basic combat unit, S307 may be executed to continue traversing the next associated basic combat unit.

[0119] If the wireless communication device associated with the basic combat unit is not consistent with the target wireless communication device in model, or the communication subnet has not been established, S307 may be directly executed to traverse the next associated basic combat unit.

[0120] S310: After the associated basic combat units of the target basic combat unit are traversed, it is determined whether the target basic combat unit has joined the communication subnet.

[0121] If you do not join the communication subnet,

[0122] S311. Initialize the target basic combat unit and establish a communication subnet.

[0123] Then, S302 may be executed to continue traversing the next target basic combat unit.

[0124] It is understandable that if the target basic combat unit has already joined the communication subnet of the associated basic combat unit, S302 can be directly executed to continue traversing the next target basic combat unit.

[0125] To Figure 2 Taking the assignment of radio stations to combat units as an example, we first traverse to tank 1. Tank 1 has no assigned wireless communication equipment and has not joined the communication subnet. Therefore, we randomly assign radio station A-1 to tank 1.

[0126] Traverse the combat units that have a direct command relationship with Tank 1, namely Tank 2 and Tank 3. First, traverse to Tank 2. If it is determined that Tank 2 has not been assigned a radio, directly assign Tank 2 a radio of the same model, A-2;

[0127] Then traverse to Tank 3. If Tank 3 has been assigned radio station A-3 and the communication subnet "Left Wing Squadron Combat Network" has been established, then Tank 1 will be directly added to the communication subnet "Left Wing Squadron Combat Network".

[0128] If tank 3 has been assigned radio station B-1 or radio station A-3 but no communication subnet has been established, all combat units with direct command relationship with tank 1 will be traversed. At this time, tank 1 has not yet joined the communication subnet. In this case, tank 1 will be initialized and a communication subnet will be established, and then the traversal will continue to the next tank.

[0129] Based on the above steps, wireless communication equipment with the same functions can be assigned based on the mutual command and communication relationships between combat units, automatically generating the assignment relationship between combat units and communication equipment. At the same time, combat units with the same command relationship will automatically establish a communication network, reducing the possibility of manual configuration errors through automatic configuration.

[0130] S400. Based on the network configuration instructions, configure parameters for each communication subnet in the combat scenario communication model.

[0131] The network configuration instructions include parameters of each communication subnet specified by the user.

[0132] After wireless communication devices are allocated and communication subnets are established, users can configure parameters for each communication subnet, including time, operating frequency, operating type, operating mode, and transmit power.

[0133] Once the parameters of a communication subnet are configured, they take effect on all wireless communication devices within the subnet, reducing manual planning workload.

[0134] In some implementations, a user may also configure parameters for a specific wireless communication device, thereby increasing flexibility.

[0135] S500. Based on the service configuration instruction, configure service parameters for each wireless communication device in the combat scenario communication model.

[0136] Furthermore, it is also necessary to define service parameters for each wireless communication device. The service parameters may include service sending address, service type, message length, interval, and number of retransmissions.

[0137] In one embodiment, except for the service sending address which needs to be manually defined by the user, all other parameters can be automatically matched based on a preset parameter model.

[0138] Specifically, see Figure 4 , Figure 4 yes Figure 1 A flow chart of an implementation method corresponding to S500.

[0139] like Figure 4 As shown, the method for configuring service parameters includes:

[0140] S501. Based on the service configuration instruction, send an address for each wireless communication device service in the combat scenario communication model.

[0141] The service configuration instruction includes a service sending address of each wireless communication device specified by the user.

[0142] S502. Call the service model of the combat scenario template library to configure the service type, message length, interval and number of retransmissions for each wireless communication device in the combat scenario communication model.

[0143] S600: Configure a channel model for each link in the communication subnet.

[0144] After configuring the communication network parameters and the service parameters of the wireless communication devices, you need to configure a channel model for the scenario to calculate channel propagation parameters such as link transmission loss, delay, multipath, and Doppler.

[0145] In one embodiment, the user may determine whether the link of the entire model adopts a single channel model or adopts multiple different signal models based on the complexity of the scenario.

[0146] Among them, the signal model can be a traditional ITU statistical model or an AI-driven model such as ChannelGPT. Users can preset the signal model library and configure the signal model by calling the signal model in the signal model library.

[0147] Specifically, see Figure 5 , Figure 5 yes Figure 1 A flowchart of an implementation method corresponding to S600 is shown in FIG.

[0148] like Figure 5 As shown, the steps of configuring the channel model include:

[0149] S601. Based on the model number configuration instruction, determine whether the combat scenario communication model is applicable to the single signal model.

[0150] Among them, the model number configuration instruction includes a single model configuration instruction and a multi-model configuration instruction. The single model configuration instruction is used to specify a single signal model applicable to the entire combat scenario communication model; while the multi-model configuration instruction is used to determine that the entire combat scenario communication model needs to adopt multiple different signal models.

[0151] First, the user determines the number of configured signal models based on the complexity of the scenario or the generalization capability of the preset signal model, and selects the signal model to be adopted from the signal model library when deciding to adopt a single signal model.

[0152] For example, when the battlefield environment is a single environment, such as an island reef environment, a single signal model can be used.

[0153] If, based on the number of models configured, it is determined that the operational scenario communication model is not suitable for a single signal model, then:

[0154] S602: traverse the links in the combat scenario communication model, and each time a target link is traversed, determine whether the operating frequencies of the two wireless communication devices in the target link are the same.

[0155] When multiple different channel models need to be used, signal model matching needs to be performed link by link.

[0156] If the two wireless communication devices of the target link operate at the same frequency, then:

[0157] S603: Based on the parameters of the wireless communication device and the elements of the basic combat unit corresponding to the wireless communication device, configure a channel model for the target link.

[0158] For two wireless communication devices operating at the same frequency, a channel model can be configured based on the parameters of the wireless communication devices and the elements of the basic combat unit. The parameters of the wireless communication devices may include operating frequency, transmit power, antenna type, and receiver sensitivity, while the elements of the basic combat unit may include the position, attitude, speed, and orientation of the basic combat unit.

[0159] Specifically, in one embodiment, signal model matching can be performed based on preset matching rules. By inputting the parameters of the wireless communication device and the element content of the basic combat unit corresponding to the wireless communication device into the preset matching rules, the signal model corresponding to the target link can be obtained.

[0160] In another embodiment, the signal model can also be matched based on a pre-trained deep learning neural network model. The parameters of the wireless communication device and the element content of the basic combat unit corresponding to the wireless communication device are input into the pre-trained deep learning neural network model to obtain the channel model corresponding to the target link.

[0161] Among them, the deep learning neural network model can adopt any classification model commonly used in this field, such as convolutional neural network, etc. The parameters of the wireless communication equipment with labeled signal models and the element content of the basic combat unit can be used as a sample set for training until the loss function converges. The specific process will not be repeated here.

[0162] S700. Formalize the parameters of the combat scenario communication model to obtain a scenario file.

[0163] Based on the above steps, the communication model and signal model settings are completed. Finally, the model parameters can be formally described to obtain the final scenario file.

[0164] In one embodiment, the parameters configured in the above steps may be converted into a standard JSON or XML format configuration file, and integrity verification may be performed to complete a formal description of a wireless communication scenario.

[0165] In another embodiment, in order to avoid communication interference between different communication networks, the formal description method also includes frequency band space-time conflict detection. Figure 6 , Figure 6 It is a flow chart of an implementation method of frequency band space-time conflict detection in this application.

[0166] like Figure 6 As shown, frequency band space-time conflict detection includes:

[0167] S10. Determine whether there are wireless communication devices with the same operating frequency in different communication subnets.

[0168] In order to avoid wireless communication devices with the same operating frequency existing in different communication subnets, in this embodiment, after the network configuration is completed, frequency band time-space conflict detection can also be performed.

[0169] If wireless communication devices with the same operating frequency exist in different communication subnets, then:

[0170] S20: trigger and save conflict warning information.

[0171] The conflict warning information is used to describe wireless communication devices with the same operating frequency. The warning information is displayed to the user to remind the user of possible signal interference problems.

[0172] S30 : Calculate, based on the channel model, the communication loss between wireless communication devices with the same operating frequency described in the conflict warning information.

[0173] After the signal model is configured, the communication loss can be calculated based on the signal model.

[0174] S40: Determine whether communication interference exists between wireless communication devices based on the parameters of the wireless communication devices and the communication loss.

[0175] Specifically, the difference P1-P2 between the transmission power P1 of the wireless communication device at the transmitting end and the receiver sensitivity P2 of the wireless communication device at the receiving end can be calculated, and then it can be determined whether P1-P2 is less than the communication loss PL. If P1-P2 < PL, it means that there will be no communication interference between the two wireless communication devices. If P1-P2 > PL, it means that communication interference will occur between the two wireless communication devices.

[0176] Furthermore, if there is no communication interference between the wireless communication devices, then:

[0177] S50: Eliminate conflict warning information.

[0178] If there is communication interference between wireless communication devices, the user needs to reconfigure the parameters of the communication subnet to avoid communication interference.

[0179] Based on the formal description methods shown in the above-mentioned embodiments, it is possible to complete the construction of a combat scenario for wireless communication, and save these data in a standardized format according to a standard format, thereby achieving the reusability of the scenario and improving the versatility of the scenario.

[0180] When performing virtual-to-real mapping of wireless communication equipment, the command relationship and network connection relationship of wireless communication equipment corresponding to basic combat units are intelligently configured, which greatly reduces the workload of combat formations in allocating communication equipment one by one and improves the efficiency of scenario planning. By intelligently configuring the channel model in the scenario, channel simulation at the scenario level and link level can be achieved, and communication conflict resolution can be supported, which greatly improves the usability of communication scenario planning.

[0181] In addition, this description method is compatible with the scenario description language of traditional combat simulation engines. The combat simulation engine can be directly used for scenario simulation, and the relationship between communication equipment networks, links, and channels can be calculated through additional modules. The corresponding communication services are sent to the actual communication equipment, and the channel simulator is connected for semi-physical simulation, which can effectively improve the authenticity of wireless communication scenario simulation.

[0186] The device allocation module 23 is used to allocate the wireless communication devices in the wireless communication device configuration table to the basic combat units of the target combat scenario, and establish a communication subnet to obtain a combat scenario communication model. Each communication subnet includes one or more wireless communication devices of the same model.
