Since the process needs personnel to intervene in the simulation deduction process through human-computer interaction, when the system simulation scene becomes more complex, the difficulty of tasks such as the judgment of the guidance intervention condition satisfaction and the grasp of the sending time of the guidance intervention instruction increases, resulting in frequent misjudgment, omission and delay.

[0026] The descriptions of the embodiments herein, including any references to directions and orientations, are for ease of description only and should not be construed as limiting the scope of the invention. The following description of preferred embodiments involves combinations of features, which may exist independently or in combination; the invention is not particularly limited to the preferred embodiments. The scope of the invention is defined by the claims.

[0027] likeFigures 1-5 As shown in the figure, the embodiment of the present application proposes a rule-based aerospace equipment system-level simulation guidance and intervention system, which comprises: a scenario loading subsystem, which is used to parse the structured data in an external scenario file to form initialization data required for guidance and intervention rule editing and situation display, the scenario loading subsystem comprising a scenario reading module and a scenario parsing module; a guidance and intervention rule editing subsystem, which is used to define, generate and send rules for guidance and intervention, the guidance and intervention rule editing subsystem comprising a rule management module, a rule design module, a rule verification module and a rule sending module; a situation display subsystem, which is used to visually display the guidance and intervention process and display detailed parameters of the guidance and intervention results, the situation display subsystem comprising a simulation data parsing module and a visual view module; and a rule guidance and intervention model, which is used to monitor the condition satisfaction of a simulation scene according to conditional logic and send a guidance and intervention instruction set according to the condition satisfaction, the rule guidance and intervention model comprising a rule parsing module, an instruction set management module and a condition calculation module.

[0028] As shown in the figure, Figure 2 In the embodiment, the scenario loading subsystem comprises a scenario reading module and a scenario parsing module, the scenario reading module is used to read scenario file information from an external simulation platform, display scenario file set summary information in a state of being simulated and having a start simulation deduction condition in a user interactive interface, when a user determines to select a certain scenario file, the scenario reading module reads the user-determined scenario file into the system; the scenario parsing module is used to extract all simulated objects, parameters of the objects and relationship data of the objects in the read-in scenario file to form initialization data required for guidance and intervention rule editing and situation display.

[0029] As shown in the figure, Figure 3 In the embodiment, the guidance and intervention rule editing subsystem comprises a rule management module, a rule design module, a rule verification module and a rule sending module, the rule management module stores and manages rule templates, the rule management module associates corresponding management rule templates according to scenario parsing data, and completes instantiation of the management rule templates according to scenario types, simulation objects, parameters of the simulation objects, relationship data of the simulation objects and corresponding task plans in the scenario parsing data to generate instantiated rules; the rule design module provides user revision of the instantiated rules, and provides rule editing functions in a graphical design panel manner; the rule verification module provides legality verification of the current rules and displays result information after the legality verification ends; the rule sending module is used to convert the graphical rule instances into structured data and send them to the rule guidance and intervention model.

[0030] As shown in the figure, Figure 4As shown, in this embodiment, the situation display subsystem includes a simulation data parsing module and a visualization view module. The simulation data parsing module is used to listen to the port where the simulation platform publishes simulation data, and parse the data of the simulation platform in real time according to the agreed communication protocol and data format and send it to the visualization view module. The visualization view module is used to display the initial situation related to the scenario based on the initialization data passed by the scenario parsing module during the initialization phase, and to filter out the data related to the current scenario based on the output data of the simulation data parsing module and according to the scenario ID during the running phase, so as to display the basic situation and guidance rule execution process information during the simulation operation.

[0031] like Figure 5 As shown, in this embodiment, the rule-guided model includes a rule parsing module, an instruction set management module, and a condition calculation module. The rule parsing module is used to parse a set of rule units from the structured data of the rules. Each rule unit includes an instruction set, a condition set, and an execution mode. The rule parsing module generates relational data between the instruction set and the condition set, sends the instruction set and the relational data to the instruction set management module for caching, and uses the condition set and the execution mode as input parameters for the condition calculation module. The instruction set management module is used to cache the instruction set and relational data sent by the rule parsing module, send instruction sets that meet the rule conditions, and release the cached instruction sets that are no longer subject to condition calculation. The condition calculation module is used to decompose the condition set input by the rule parsing module into condition units according to nested logic and AND / OR relational logic, and start condition calculation according to the execution mode input by the rule parsing module. When the condition is met, the instruction set management module is triggered to send a message about the instruction set. When the condition calculation ends, the instruction set management module is triggered to release a message about the instruction set cache.

[0032] like Figure 8 The diagram shown is a flowchart of a rule-based aerospace equipment system-level simulation guidance and intervention method according to an embodiment of the present invention. The method includes the following steps:

[0033] S10, through the scenario loading subsystem, parses the structured data in the external scenario file to form the initialization data required for instruction rule editing and situation display;

[0034] S20, through the guidance rule editing subsystem, defines, generates, and sends rules for guidance intervention;

[0035] S30, through the situation display subsystem, provides data visualization during the intervention process and detailed parameter display of the intervention results; and

[0036] S40, monitoring the condition satisfaction of the simulation scenario according to the condition logic by the rule guidance model, and sending a guidance instruction set according to the condition satisfaction.

[0037] As Figure 6 shown, in combination with the rule-based space equipment system-level simulation guidance intervention system and method of the present embodiment, a space equipment system-level simulation guidance intervention method is exemplified. Through structured data analysis processing, multi-thread parallel processing and other technical approaches, the rule generation function, rule logic analysis and management function, rule logic legality verification function, rule logic execution and monitoring function and the like that meet the requirements of complex system simulation scenario guidance intervention are realized on the basis of automation. The specific technical solutions are as follows:

[0038] (1) The rule is generated based on the content data of a system-level simulation scenario file. The rule includes multiple rule units, which are independent of each other. The rule unit includes three aspects, a condition set, a guidance instruction set and an execution mode of the rule unit. The condition set is n{n|n∈N} condition units combined by and relationship. The guidance instruction set is a group of guidance instruction units that meet the condition. The execution mode of the rule unit includes single execution, multiple execution and loop execution.

[0039] Among them, the condition unit type includes but is not limited to absolute time, relative time, relative distance, regional position relationship, object parameter (including environmental object). The instruction unit type includes but is not limited to: parameter change, path change, command relationship change, communication relationship change, damage state change, firepower plan change.

[0040] (2) After the rule is generated, it is sent to the simulation engine (i.e. simulation scenario) that has started the scenario.

[0041] (3) The simulation engine forwards the rule to the rule guidance model entity, and the rule guidance model entity starts the rule guidance operation according to the rule definition content.

[0042] (4) The rule guidance model entity disassembles the guidance rule into rule units, so that the calculation logic of each rule unit is independently and parallelly run.

[0043] (5) The rule guidance model runs the rule unit according to the execution mode type information of the rule unit.

[0044] (6) In each execution mode, the condition set in the rule unit is split into condition units. Each simulation step judges each condition unit, and obtains the calculation result of the condition set according to the and logic.

[0045] (7) When the condition set calculation result is true, the rule guide template entity is guided, the condition set information is output, and the instructions are sent to the corresponding simulation entity in the simulation scene according to the executor information of each instruction in the intervention instruction set corresponding to the condition set.

[0046] (8) The condition set information and the instruction set information obtained by the guide state module are saved to the guide database, and the obtained information is displayed.

[0047] (9) The parameter detail window of each guide instruction receiving object is displayed by the state display subsystem, and the change of the parameter details of each frame is tracked and displayed.

[0048] Referring to Figure 7 , an example of expressing the guide rules by a graphical multi-layer nested relationship in the above method is shown. Figure 7 In the condition definition area, the condition items 1, 2 and 3 are expressed as an AND relationship by the condition group (AND), and the condition group (AND), the condition item 4 and the condition item 5 are expressed as an OR relationship by the condition group (OR). The intervention instruction item set in the intervention instruction definition area is all the intervention instructions that satisfy the condition logic.

[0049] In summary, the present application solves the problems of the traditional guide function, such as easy to miss, delay, timeliness is not strong, and complex rule support is not strong. The main performance is that the definition and analysis of complex instructions are realized by the multi-layer nested mode of the condition unit through the AND or relationship, and the response loop of rule analysis, condition calculation and instruction sending is shortened by the rule guide model, which improves the efficiency of rule guide execution, ensures the execution efficiency of simulation deduction, and ensures the real-time of guide intervention. At the same time, the state display subsystem records and realizes the condition satisfaction result and the guide instruction sending result of the rule guide, and tracks and displays the detailed parameter change of the target simulation entity of the instruction, so that the rule guide process is complete closed loop. While realizing the full process automation, the adaptability of the complex guide rules of the space equipment system simulation is ensured, the guide function of the multi-level complex rule logic is supported, and the accuracy and real-time of the guide intervention process execution are ensured.

[0050] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
