Description

Technical Field

[0001] The invention relates to the technical field of marine deck aviation support training, testing and evaluation simulation, and in particular to a simulation scenario generation method for evaluating a deck aviation support mission plan. Background Art

[0002] The simulation scenario method for evaluating the shipboard aviation support mission plan is a simulation of the actual combat training system. Corresponding to the military scenario, the concept of simulation scenario is proposed. Military scenarios are mainly used by military personnel to imagine and assume the situation of combat and military exercises in the form of scenario documents. Simulation scenarios require the initialization data required by the simulation system and the setting data of some events during the simulation operation. The analysis and design of simulation scenarios refers to determining the description content and description method of simulation scenarios.

[0003] XML is an extensible markup language that can be used to mark data and define data types. It is a source language that allows users to define their own markup languages. XML is a standard general-purpose markup language with good scalability, separation of content and form, and strict grammatical requirements. XML's custom description method facilitates data exchange between different fields, different platforms, and different systems. It has a good hierarchy and tree structure, and can clearly express the logical and hierarchical relationship of the hypothetical content. Compared with the XML language, the use of XML Schema for hypothetical description can flexibly implement the tagging and constraints of hypothetical content, effectively describe complex hypothetical content and organization, and can be parsed by XML parser. XML Schema has strong scalability, can support more data types, and can be constrained in a more standardized manner.

[0064] Input the mission plan in the form of a Gantt chart, and extract information including the number of carrier-based aircraft, the type of carrier-based aircraft, the number of carrier-based aircraft, the mission number of each carrier-based aircraft, the mission start time, the mission end time, the mission duration, etc. through the mission parser; and convert the extracted information into a document in XML format and store it in the mission scenario element of the scenario element;

[0065] See also Figure 3 , Figure 3 It is a flowchart of the task parser, which parses the Gantt chart of the carrier-based aircraft aviation support scheduling plan into a document in XML format. The method flow includes the following steps:

[0066] The first step is information extraction: extract all carrier-based aircraft information and task information from the Gantt chart of the task plan; extract the number of each carrier-based aircraft, the number of each carrier-based aircraft, the number of task plans, the task number, the task start time, the task end time, the task duration, etc. by parsing the row objects, row numbers, column objects, column numbers, image blocks of each row, etc. of the Gantt chart;

[0068] Step 2: Information analysis: Based on the information obtained from the first step, refer to Figure 3 The flowchart of the task parser numbers the carrier aircraft and tasks respectively. If the carrier aircraft No. i matches the task No. j, the task plan is claimed, and the start time, end time and duration of the task are obtained, and recorded and written in the XML document; if there is no match, it continues to pair with the next task until each carrier aircraft corresponds to each task, and the tasks of each carrier aircraft are listed in chronological order. After the XML document is completed, the loop ends and the document is saved. (This step is an innovation)

[0069] The third step is to write an XML document: Write an XML document for the mission information corresponding to the carrier-based aircraft parsed in the second step.

[0071] To explain the task parser more clearly, Figure 4 This is a task parser example diagram. For further explanation of the task parser using a simple example, please refer to Figure 4 , this example parses the carrier-based aircraft scheduling plan in the form of a Gantt chart into an XML format document; Figure (a) is a Gantt chart of a high-intensity task plan for carrier-based aircraft. As can be seen from the figure, the horizontal axis is the time axis, the time t ranges from 0 to 1080, and the task is performed for 18 hours every day. The vertical axis is the carrier-based aircraft number, and the carrier-based aircraft number is 1-42 from top to bottom. The task number is 1-6, which are task 1 (red) catapult takeoff, task 2 (green) flight, task 3 (blue) Marshall waiting route, task 4 (yellow) arrested landing, task 5 (pink) maintenance / shutdown, and task 6 (cyan) support station / refueling. The task start time, task end time, and task duration of each carrier-based aircraft can be clearly obtained from the figure; pass it through After parsing by the task parser, an XML document as shown in Figure (b) can be obtained, which has good hierarchy. The sub-elements of the output task plan include the number of carrier-based aircraft 42 and the carrier-based aircraft numbers 1-42. The sub-elements of the carrier-based aircraft numbers include the task number, task start time, task end time, and task duration. As can be seen from Figure (a), the first task number of carrier-based aircraft 1, carrier-based aircraft 2, and carrier-based aircraft 3 is 1, the start time of task 1 is 0, the end time is 10, and the duration is 10; the first task number of carrier-based aircraft 4 is 5, the start time of task 5 is 0, the end time is 12, and the duration is 12. Therefore, this example converts a Gantt chart of a high-intensity carrier-based aircraft task plan into a document in XML format.

[0072] Step 3: Initialize the scenario information and generate the simulation scenario file;

[0073] Step 3.1: Initialize scenario background and scenario description;

[0074] The method for initializing the scenario background and scenario description includes: parsing the corresponding part of the XML Schema scenario markup language file, loading the scenario background and scenario description, the scenario background is what kind of task is performed for what event, the scenario description includes background time, duration, and scenario goal, and the goal is to describe the effect to be achieved through this task.

[0075] Step 3.2: Initialize environment information;

[0076] The method for initializing the deck environment, weather conditions, and sea state information of the deck aviation support includes: parsing the corresponding part of the XML Schema assumption markup language, loading the initialization, loading different deck environments according to the deck type, including the basic attributes and spatial attributes of the four areas of the take-off area, landing area, parking area, and island area; displaying different weather conditions according to temperature, air pressure, sky cloud cover, precipitation, wind speed, and wind direction; and loading the sea state level of the marine environment in real time according to the size of wind and waves.

[0077] Step 3.3: Initialize entity information;

[0078] The method of initializing the position, state and other information of each entity includes: parsing the corresponding part of the XML Schema assumption markup language file, loading entity parameters, including initial state value, mount, weapon, fuel volume, etc., controlling the entity position information through longitude and latitude, etc.

[0079] Step 4: Perform simulation and evaluation of the shipboard aviation support mission plan.

[0080] In the computer simulation environment of the shipboard aviation support system, based on steps 2 and 3, the assumption information is initialized and the parsed mission plan information is input. With the entity as the carrier, the scheduling task operation is performed according to the action information at each moment, and the shipboard aviation support simulation assumption deduction is carried out. The scheduling task plan is evaluated according to the output data information, and the simulation assumption deduction and evaluation of the shipboard aviation support mission plan are realized.

[0081] The above describes the specific operation and main features of the present invention. Based on the XML Schems scenario markup language, the scenario description information of the shipboard aviation support is improved and enriched, the content and rule system of the aviation support scenario are clearly expressed, and it can be supplemented and expanded according to specific needs; a task parser is set to parse the input scheduling task plan into an XML document and store it in the task scenario element; for the complex marine shipboard environment, different physical equipment, environmental conditions, support conditions, etc. are generated by assumption, and a variety of shipboard aviation support task scheduling plans are input for simulation assumption deduction and evaluation, providing a comprehensive, standard, and real-life simulation deduction environment scenario generation for the evaluation of shipboard aviation support task scheduling plans, making the training tasks in the marine shipboard environment more standardized and hierarchical, making the training more orderly and more practical, reducing the cost required for actual training, and comprehensively improving the efficiency of aviation support.
