Description

Technical Field

[0001] The present invention relates to the task planning technology in the field of environmental construction, and particularly to a method for task planning and deduction of an unmanned aerial platform based on environmental construction, which is applicable to the scenario of blue-side training environmental construction and can also be applied to the field of task planning and deduction in other scenarios. Background Art

[0002] Unmanned aerial platforms generally include unmanned aerial vehicles, airships, unmanned helicopters, and small unmanned aerial vehicles. The blue side, also known as the "threat target" or "imaginary enemy", is an organization specifically formed to simulate the enemy according to the enemy's establishment, equipment, and tactical principles. The blue side uses various types of unmanned aerial platforms to simulate the enemy (satellites, precision-guided weapons, aircraft) to create an air threat in a specific area. There are two difficulties in task planning in the ground station system:

[0003] First, there are differences in capabilities and operational uses between unmanned aerial platforms and the blue-side threats to be created, especially the differences from threats such as satellites and precision-guided weapons are very large.

[0004] Second, the number of unmanned aerial platforms faced in task planning is large and the model differences are significant. Existing task planning for unmanned aerial platforms is developed for specific models of unmanned aerial platforms and can only support one model of unmanned aerial platform to perform specific tasks. Moreover, different types of unmanned task planning systems are usually not compatible with each other.

[0005] In addition, traditional task planning does not have the ability to deduce, cannot intuitively display the dynamic process of task execution for combat commanders and soldiers, and is not conducive to unmanned aerial platform operators understanding the task in advance. Summary of the Invention

[0006] In view of this, the present invention proposes a method for task planning and deduction of an unmanned aerial platform based on environmental construction. This method equivalently decomposes the complex task requirements of environmental construction into small tasks that can be executed by the unmanned aerial platform, and then conducts task planning such as route, payload, and link communication for the unmanned aerial platform to generate an unmanned aerial platform task plan. Through simulation analysis and dynamic demonstration, it comprehensively analyzes and verifies flight safety and task feasibility.

[0007] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0008] A method for task planning and deduction of an unmanned aerial platform based on environmental construction specifically includes the following steps:

[0009] (1) Receive the environmental construction requirements issued by the superior;

[0010] (2) If the environmental configuration requirement is a task of the blue - side simulation object, perform equivalent processing to convert the task of the blue - side simulation object into a task that can be executed by an unmanned aerial platform; otherwise, execute step (3); the tasks of the blue - side simulation object include simulated satellite reconnaissance tasks, simulated precision - guided weapon strike tasks, simulated reconnaissance - strike tasks, and simulated interference tasks;

[0011] (3) Analyze the environmental configuration requirement to determine the type of simulation task. Analyze and decompose complex simulation tasks, and extract the task area, time requirements, payload usage requirements, and other constraint conditions for the activities required by the unmanned aerial platform to achieve specific task effects. Other constraint conditions include speed and dimension;

[0012] (4) Determine the basic elements of environmental information, expected effects, and available resource environment configuration according to the requirements and constraint conditions extracted in step (3), and complete task quantification by integrating unmanned aerial platform information and mission payload information, and conduct screening of unmanned aerial platforms and payloads;

[0013] (5) Form a mission scenario based on the selection results of the unmanned aerial platform and the payload;

[0017] Among them, the specific steps of step (2) are as follows:

[0018] (201) Analyze to obtain the area, entry time, and duration for which the unmanned aerial platform needs to configure a threat by simulating the blue - side's mission execution or taking the blue - side's mission objective as the object, and comprehensively consider the flight ability of the unmanned aerial platform to identify the acquisition area and time of the unmanned aerial platform for forming an air threat;

[0019] (202) Determine the mission modes that need to be completed by the unmanned aerial platform in the mission area according to the blue - side's mission mode, including coverage search, fixed - point reconnaissance, and fixed - point strike;

[0020] (203) Determine the corresponding working mode of the payload according to the blue - side's working mode;

[0021] (204) According to the characteristics of the blue side's mission, through look-up table and interpolation calculation methods, calculate the constraint conditions of the flight altitude, speed, and attitude that the unmanned aerial platform should maintain to achieve the mission effect.

[0022] Among them, in step (6), mission planning is carried out according to the mission scenario to generate the mission plan for the unmanned aerial platform. The specific steps are as follows:

[0023] (601) Combine the mission scenario, calculate the approximate route of the unmanned aerial platform according to the take-off and landing airport of the unmanned aerial platform and the assigned mission situation, and analyze the communication shielding situation of the unmanned aerial platform in combination with the terrain to obtain the flight corridor of the unmanned aerial platform;

The mission planning results that fail the inspection are readjusted for task allocation until the requirements of the environmental configuration are met.

[0028] Among them, the specific steps of step (7) are as follows:

[0029] (701) Start the simulation;

[0030] (702) Analyze the mission scenario to determine the time nodes and spatial regions of the simulation deduction, and at the same time determine the target position information, threat area information, and meteorological information;
