Description

Technical Field

[0001] This invention relates to novel aircraft air traffic management technology, and in particular to a method and system for route construction and visualization of flight rules based on dynamic three-dimensional digital commands. Background Technology

[0002] With the rapid development of new aircraft such as drones and electric vertical takeoff and landing (eVTOL) aircraft, airspace, especially low-altitude airspace, is facing unprecedented traffic pressure. Traditional air traffic management mainly relies on fixed routes, pre-arranged flight plans, voice communication, and rule manuals in text and chart form. This approach has the following inherent drawbacks: 1. Rigid and outdated: Traditional airspace rules are static and fixed, making it difficult to update and load rules quickly and dynamically based on real-time airspace status, weather changes, or emergencies, resulting in the airspace structure being difficult to "transform from static to dynamic". 2. Complex and error-prone: The aircraft or pilot needs to manually interpret complex textual and graphical rules (such as graphics, tables, and written restrictions), and relies on indirect instructions for flight control, resulting in low efficiency and significant differences in human-machine understanding and safety challenges. 3. Safety challenges: For non-cooperative or highly automated aircraft, there is a lack of direct, digital commands that enable the aircraft to "understand and fly clearly," resulting in limited perception and avoidance capabilities.

[0003] Existing drone management systems (such as UTM) attempt to integrate some rules, but lack unified, three-dimensional, and dynamic rule injection and expression capabilities, making it difficult to transform abstract flight restrictions into three-dimensional digital commands that the aircraft can directly execute.

[0004] Therefore, there is an urgent need for an innovative management mechanism that can dynamically and three-dimensionally manage airspace rules and enable the loading of digital rules commands and their direct execution by aircraft.

[0005] It should be noted that the information disclosed in the background section above is only for understanding the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0006] The main objective of this invention is to overcome the deficiencies in the aforementioned background technology and provide a method and system for route construction and visualization of flight rules based on dynamic three-dimensional digital commands.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A method for route construction and flight rule visualization based on dynamic 3D digital commands includes the following steps: S01. Rule-based instruction: Semantically analyze and logically decompose textual flight regulations and airspace management rules to generate dynamic three-dimensional digital instructions that are bound to the airspace grid and time dimension; S02. Dynamic road construction: Based on the dynamic three-dimensional digital instructions, the airspace grid is screened for navigability, and the navigable airspace grids are linked according to spatial connection relationships to plan and form a three-dimensional dynamic route that conforms to the rule constraints; S03. Visual presentation: The three-dimensional dynamic flight path and the corresponding dynamic three-dimensional digital commands are rendered into visual graphics to present the flight rules in a three-dimensional way; S04. Comply with regulations: During flight, obtain dynamic three-dimensional digital commands corresponding to the airspace grid where the aircraft is located and the airspace it is about to enter in real time, and execute compliant flight actions or adjustments according to the commands.

[0008] Further, step S01 includes: Semantic analysis of flight rules is performed to extract spatial, temporal, and behavioral conditions. The parsed rule logic is bound to specific spatial grid identifiers to generate structured, dynamic, three-dimensional digital instructions. The dynamic three-dimensional digital instructions include at least spatial constraint instructions for limiting the accessible airspace range, speed limit instructions for limiting the flight speed range, and action permission instructions for indicating the types of flight actions that can be performed, and each instruction is effective only under the corresponding airspace grid and specific time conditions.

[0009] Further, step S02 includes: Based on the start and end points of the flight mission and the planned flight time, the accessibility of each grid cell in the airspace grid model is judged and screened according to dynamic three-dimensional digital commands. Based on spatial connectivity, passable grid cells that meet the command constraints are sequentially linked to form a continuous three-dimensional dynamic route that runs through the starting point and the ending point. When changes in the external environment cause dynamic three-dimensional digital commands for some airspace grids to be updated, the affected flight routes are replanned to generate updated compliant flight routes.

[0010] Further, step S03 includes: The spatial restriction commands in the dynamic three-dimensional digital commands are rendered as three-dimensional electronic fences; The traversable paths in the three-dimensional dynamic air route are rendered as virtual air corridors; The display is presented through an augmented reality interface or a 3D map interface, and the rules and instructions corresponding to a specific airspace grid area are highlighted before the aircraft enters that area.

[0011] Further, step S04 includes: During flight, the aircraft subscribes to and obtains dynamic 3D digital commands corresponding to its current position and predicted path from the central management system in real time. The instructions are used as input to the flight control system, which automatically adjusts the flight status or pushes auxiliary decision-making information to the operator, such as pushing correction instructions or providing visual prompts. When a deviation from the current command requirements is detected in the flight status, or when the command itself is updated, a corrective command is pushed to the aircraft to guide it back to compliant flight.

[0012] A flight route construction and visualization flight rules system based on dynamic three-dimensional digital commands, comprising: The rule digitization parsing engine is used to parse textual flight rules and transform them into machine-readable, dynamic, three-dimensional digital instructions bound to the airspace grid and time dimension. The grid route construction module is used to select passable grids in the airspace grid and link them to generate a three-dimensional dynamic route that conforms to the rule constraints, based on the dynamic three-dimensional digital instructions. A visual interactive terminal is used to receive and render the three-dimensional dynamic flight path and the corresponding dynamic stereo digital commands, and present them in a stereo graphical manner. The dynamic guidance module is used to compare and guide the aircraft based on its real-time status and corresponding dynamic 3D digital commands during flight, ensuring compliant flight.

[0013] Furthermore, the system also includes a rule dynamic mapping module, which is used to update the dynamic three-dimensional digital instructions corresponding to the affected airspace grid in real time when rule adjustments are triggered by changes in the external environment, and synchronize the updates to the route construction and flight guidance stages.

[0014] Furthermore, the rule digitization analysis engine is specifically used to structurally encode the spatial conditions, temporal conditions, and behavioral conditions in flight rules, generate dynamic three-dimensional digital instructions that include spatial constraint instructions, speed limit instructions, and action permission instructions, and bind the instructions to a specific airspace grid and time period to achieve spatiotemporal dynamic expression.

[0015] Furthermore, the grid route construction module is specifically used to perform path search and optimization based on dynamic three-dimensional digital commands in the airspace grid model according to flight mission requirements, generate a three-dimensional dynamic route that meets the command constraints throughout the entire process, and trigger local replanning of the affected flight segments when the command is updated.

[0016] Furthermore, the visual interactive terminal presents the visual information through an augmented reality interface or a 3D map interface; The dynamic guidance module interacts with the central management system through airborne communication equipment to realize real-time subscription of digital commands, status comparison and correction command push, forming a flight control closed loop with digital commands as the core.

[0017] The present invention has the following beneficial effects: This invention provides a method and system for flight route construction and visualization based on dynamic three-dimensional digital commands. It effectively solves the problems of existing technologies where flight rules mainly rely on text, charts, or manual instructions, leading to high understanding costs, complex execution, and susceptibility to ambiguity and errors. The core of this invention lies in transforming static airspace into a dynamic interactive environment. It utilizes airspace grid technology to construct a dynamic flight route network and parses traditional flight rules into dynamic three-dimensional digital commands bound to the airspace grid and time dimension. This transformation changes flight rules from "human-readable rules" to "machine-readable commands," and from "post-event correction" to "pre-event guidance," achieving dynamic expression, automatic execution, and visualization of rules.

[0018] The dynamic three-dimensional digital instructions, serving as a digital carrier of flight rules, essentially transform rules existing in the form of text, clauses, or manual instructions into digital instruction units with clear structures and parameter constraints. By binding them to airspace grid units and the time dimension, rules are no longer merely global constraints but are transformed into local constraints acting on specific spatial locations and time periods, achieving refined management of flight rules in both space and time. This not only supports rule constraints for individual flight missions but also serves as a fundamental control unit in a continuously operating airspace management system. Rules exist in a unified data structure, possessing reusability and composability, enabling different modules to collaborate based on the same rule expression. For example, instructions generated by the rule digital parsing engine can directly serve as the planning basis for the grid route construction module and the execution basis for the dynamic guidance module, thereby achieving centralized management and distributed execution of rules at the system architecture level. This forms a closed loop of rule formulation, updating, and execution, improving the overall consistency and controllability of airspace management. Furthermore, different instructions can be bound to the same airspace grid at different time periods, supporting a time-segmented management mode, making airspace resource utilization more flexible, and providing a sustainable technical foundation for expanding to city-level and regional-level low-altitude airspace operation scenarios.

[0019] During the route construction phase, this invention uses dynamic 3D digital commands as constraints for route planning, unifying the route generation process with the rule execution process. The route is not generated independently, but dynamically constructed within an airspace grid under rule constraints. This makes the route itself the carrier of rule execution, reducing the possibility of rule conflicts during flight from the outset. During the flight execution phase, a closed-loop execution system centered on digital commands is constructed through a dynamic guidance module. The aircraft continuously receives commands corresponding to its current position and predicted path, and adjusts its flight status in real time accordingly. This transforms rule execution from "post-event inspection" to "real-time guidance" and "advance constraints."

[0020] Meanwhile, this invention uses a visual interactive terminal to display dynamic 3D digital commands in a three-dimensional way, transforming invisible and difficult-to-understand text rules into intuitive and perceptible spatial objects. For example, spatial restrictions are rendered as 3D electronic fences, and permitted paths are rendered as virtual air corridors, significantly reducing the cost of rule understanding and improving the consistency and accuracy of execution. Through the above technical solutions, this invention establishes a collaborative working mechanism at multiple levels, including rule generation, route construction, flight execution, and rule presentation.

[0021] Compared with existing technologies, this invention has significant advantages: First, by binding rules with airspace grids and the time dimension, it achieves real-time updates and immediate effectiveness of flight rules, enabling airspace management to quickly respond to dynamic situations such as weather changes and emergencies, demonstrating the advantages of dynamism. Second, it realizes machine-to-machine rule transmission and execution, reducing reliance on human understanding and intervention, lowering the risk of human operation, and improving operational efficiency and safety, demonstrating the advantages of automation. Third, by presenting rules in a three-dimensional visualization manner, it lowers the understanding threshold and enhances the perception of airspace status by operators and supervisors, demonstrating the advantages of intuitiveness. Fourth, the rules exist in the form of digital instructions, which are easily adapted to different types of aircraft and management systems, suitable for large-scale, high-density flight scenarios, and have strong scalability.

[0022] In summary, this invention constructs a flight rule management and execution system with dynamic three-dimensional digital instructions at its core. This system ensures that rules exist in a unified digital form at each stage of generation, display, and execution, realizing a complete closed loop from rule parsing, route construction, visualization, to flight execution. This significantly reduces the need for manual intervention, effectively improves flight safety and operational efficiency in complex airspace environments, and provides reliable technical support for airspace management in high-density, automated flight scenarios.

[0023] Other beneficial effects of the embodiments of the present invention will be further described below. Attached Figure Description

[0028] The embodiments of the present invention will be described in detail below. It should be emphasized that the following description is merely exemplary and not intended to limit the scope and application of the present invention.

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of the present invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] This invention aims to address the problems of traditional flight rules relying on manual interpretation, low execution efficiency, and susceptibility to errors. It proposes a method for flight rule construction and visualization based on dynamic three-dimensional digital instructions. This method transforms textual rules into dynamic three-dimensional digital instructions bound to airspace grids and time dimensions, enabling machine-readable and three-dimensional visualization of flight rules. By supporting dynamic route construction and real-time guidance, it significantly improves the automation level and operational safety of airspace management. Ultimately, it enables aircraft to achieve the effect of "understandable and clear" flight rules when performing missions, reducing the need for manual intervention and operational risks.

[0031] See Figure 1 This invention provides a method for route construction and flight rule visualization based on dynamic three-dimensional digital commands, comprising the following steps: Step S01. Rule-based instruction: Semantically analyze and logically decompose the static textual flight regulations and airspace management rules (including control requirements, etc.) to generate dynamic three-dimensional digital instructions that are bound to the airspace grid and time dimension.

[0032] In some embodiments, step S01 includes: performing semantic parsing on the flight rules to extract the spatial conditions, temporal conditions, and behavioral conditions therein; binding the parsed rule logic with specific airspace grid identifiers to generate structured coded dynamic stereo digital instructions; wherein the dynamic stereo digital instructions include at least spatial constraint instructions for limiting the airspace that can be entered, speed limit instructions for limiting the flight speed range, and action permission instructions for indicating the types of flight actions that can be performed, and each instruction is effective only under the corresponding airspace grid and specific time conditions.

[0033] The semantic parsing process can be performed by manually annotating historical rule texts to construct a rule knowledge graph and training samples, and then using rule template matching or machine learning models (such as Named Entity Recognition (NER) and relation extraction models). In actual deployment, airspace administrators can also first decompose and annotate the rules using graphical tools, and the system can then convert them into structured digital instructions. These dynamic three-dimensional digital instructions can be encoded using structured data objects or message formats (such as those defined based on serialization formats like JSON, XML, or Protocol Buffers).

[0034] Step S02. Dynamic route construction: Based on the dynamic three-dimensional digital instructions, the airspace grid is screened for navigability, and the navigable airspace grids are linked according to spatial connection relationships to plan and form a three-dimensional dynamic route that conforms to the rule constraints, thereby realizing the construction of compliant routes with the help of the airspace grid.

[0035] In some embodiments, step S02 includes: judging and filtering the drivability of each grid cell in the airspace grid model according to the start point, end point and planned flight time of the flight mission, based on dynamic three-dimensional digital instructions; linking the drivable grid cells that meet the instructions in sequence based on spatial connection relationships to form a continuous three-dimensional dynamic flight route that runs through the start point and end point; and replanning the affected flight route segments when changes in the external environment cause the dynamic three-dimensional digital instructions of some airspace grids to be updated, so as to generate updated compliant flight routes.

[0036] The spatial grid can be divided into three-dimensional grids of different scales according to spatial complexity and management requirements. The granularity of the grid is a trade-off between accuracy and computational efficiency, and can be configured and optimized according to actual computing power and spatial management needs. The spatial grid model and its corresponding instruction set can be managed using spatial databases or spatiotemporal indexing technology to support fast querying and updating.

[0037] Step S03. Visual presentation: The three-dimensional dynamic flight path and the corresponding dynamic three-dimensional digital instructions are rendered into three-dimensional electronic fences, virtual air corridors or graphic signs and other visual graphics to present the flight rules in a three-dimensional way.

[0038] In some embodiments, step S03 includes: rendering the spatial restriction instructions in the dynamic three-dimensional digital instructions as a three-dimensional electronic fence; rendering the passable paths in the three-dimensional dynamic flight path as virtual air traffic corridors; displaying them through an augmented reality interface or a three-dimensional map interface, and highlighting the rule instructions corresponding to the specific airspace grid area before the aircraft is about to enter the specific airspace grid area.

[0039] Step S04. Execute in Accordance with Regulations: During flight, the system acquires in real-time dynamic 3D digital commands corresponding to the airspace grid where the aircraft is located and the airspace it is about to enter, and executes compliant flight actions or adjustments based on these commands. The system employs a dynamic expression mechanism to reduce information interference and improve rule execution efficiency.

[0040] In some embodiments, step S04 includes: during flight, the aircraft subscribes to and obtains dynamic stereo digital commands corresponding to its current position and predicted path from the central management system in real time; the commands are used as input to the flight control system, which automatically adjusts the flight status or pushes auxiliary decision-making information to the operator, such as pushing correction commands or providing visual prompts; when a deviation is detected between the flight status and the current command requirements, or when the command itself is updated, a correction command is pushed to the aircraft to guide it back to compliant flight.

[0041] See Figure 2 This invention also provides a flight route construction and visualization system based on dynamic 3D digital commands, including a rule digitization analysis engine, a grid flight route construction module, a visualization interactive terminal, and a dynamic guidance module. The rule digitization analysis engine is used to semantically parse and logically decompose textual flight rules and airspace management rules, transforming them into machine-readable dynamic 3D digital commands bound to an airspace grid and a time dimension. The grid flight route construction module, connected to the rule digitization analysis engine, is used to select passable grids in the airspace grid based on the dynamic 3D digital commands and link them to generate 3D dynamic flight routes that conform to rule constraints, thus enabling the construction of compliant flight routes using the airspace grid. The visualization interactive terminal, connected to the grid flight route construction module, is used to receive and render the 3D dynamic flight routes and corresponding dynamic 3D digital commands, presenting them in a 3D graphical manner such as 3D electronic fences, virtual air corridors, or graphic markers. The dynamic guidance module interacts with the rule digitization analysis engine and the visualization interactive terminal, comparing and guiding the aircraft during flight based on its real-time status and the corresponding dynamic 3D digital commands, enabling the aircraft and operator to intuitively identify airspace restrictions and ensure compliant flight.

[0042] In some embodiments, the route construction and visualization flight rule system further includes: a rule dynamic mapping module, which is connected to the rule digital parsing engine, the grid route construction module and the dynamic guidance module; the rule dynamic mapping module is used to update the dynamic three-dimensional digital instructions corresponding to the affected airspace grid in real time when the rule adjustment is triggered by changes in the external environment, and synchronize the update to the route construction and flight guidance stage.

[0043] In some embodiments, the rule digitization parsing engine is specifically used to structure and encode the spatial conditions, temporal conditions, and behavioral conditions in flight rules, generate dynamic three-dimensional digital instructions that include spatial constraint instructions, speed limit instructions, and action permission instructions, and bind the instructions to a specific airspace grid and time period to achieve spatiotemporal dynamic expression.

[0044] In some embodiments, the grid route construction module is specifically used to perform path search and optimization based on dynamic three-dimensional digital commands in the airspace grid model according to flight mission requirements, generate a three-dimensional dynamic route that meets the command constraints throughout the entire process, and trigger local replanning of the affected flight segments when the command is updated.

[0045] In some embodiments, the visual interactive terminal presents the data through an augmented reality interface or a 3D map interface; the dynamic guidance module interacts with the central management system through airborne communication equipment to realize real-time subscription of digital commands, status comparison and correction command push, forming a flight control closed loop with digital commands as the core.

[0046] In view of the above, the present invention addresses the problem that existing flight rules are mainly in the form of text, charts or manual instructions, which rely on human understanding and execution, resulting in high cost of rule understanding, complex execution and easy ambiguity and error. The present invention provides a technical solution for route construction and flight rule management that can express flight rules digitally and three-dimensionally, and can be automatically understood and executed by aircraft.

[0047] This invention transforms traditional static and abstract flight rules into dynamic three-dimensional digital instructions bound to airspace grids and time dimensions, changing flight rules from "human-readable rules" to "machine-readable instructions" and from "post-event correction" to "pre-event guidance." This enables the dynamic expression, automatic execution, and visualization of flight rules, reducing flight operation risks and improving airspace operation efficiency.

[0048] In this invention, the dynamic three-dimensional digital instruction serves as a digital carrier of flight rules. Essentially, it transforms flight rules, which originally existed in the form of text, clauses, or manual instructions, into digital instruction units with clear structures and parameter constraints, enabling the flight rules to be automatically parsed, reasoned, and executed by the system.

[0049] The dynamic three-dimensional digital commands are bound to the airspace grid cells and the time dimension, so that flight rules no longer exist only as global constraints, but are transformed into local constraints that act on specific spatial locations and specific time periods, thereby realizing the refined management of flight rules in space and time.

[0050] In this invention, the dynamic three-dimensional digital instructions are not only used for rule constraints in single flight missions, but also serve as a basic control unit in a continuously operating airspace management system. By transforming flight rules into digital instructions bound to airspace grids and time conditions, the rules become reusable and composable, thereby supporting the parallel operation of different flight missions in the same airspace environment.

[0051] The dynamic 3D digital instructions exist in the system in a unified data structure, enabling different modules to work collaboratively based on the same rule expression. For example, the instructions generated by the rule digitization parsing engine can serve as the planning basis for the grid route construction module and as the execution basis for the dynamic guidance module, thereby avoiding problems such as repeated rule parsing and inconsistent rule understanding in traditional systems.

[0052] Through this unified rule expression mechanism, the present invention realizes centralized management and distributed execution of flight rules at the system architecture level, forming a closed loop of rule formulation, updating and execution, thereby improving the overall consistency and controllability of airspace management.

[0053] Furthermore, this invention allows the same airspace grid to be bound to different dynamic 3D digital commands at different time periods, thereby supporting a time-segmented management mode. For example, some airspace can be set as high-priority passage areas during specific time periods, while reverting to normal management status during other time periods, making airspace resource utilization more flexible.

[0054] Through the above methods, the present invention is not only applicable to a single aircraft or a small number of flight missions, but can also be extended to city-level and regional-level low-altitude airspace operation scenarios, providing a sustainable and expandable technical foundation for subsequent intelligent airspace management.

[0055] In the route construction phase, this invention uses dynamic three-dimensional digital commands as constraints for route planning, thus unifying the route generation process with the flight rule execution process in terms of technical logic. The route is not independent of rule generation, but rather dynamically constructed within an airspace grid under rule constraints, making the route itself the carrier of rule execution, thereby reducing the possibility of rule conflicts during flight from the outset.

[0056] During the flight execution phase, this invention constructs an execution closed loop centered on digital commands through a dynamic guidance module. The aircraft continuously receives dynamic 3D digital commands corresponding to its current position and predicted path during flight, and adjusts its flight status in real time according to these commands, transforming flight rules from "post-flight checks" to "real-time guidance" and "advance constraints."

[0057] Meanwhile, this invention uses a visual interactive terminal to display dynamic three-dimensional digital instructions in a three-dimensional way, transforming flight rules from invisible and difficult-to-understand text rules into intuitive and perceptible spatial objects, effectively reducing the cost of understanding the rules and improving the consistency and accuracy of flight rule execution.

[0058] Through the above technical solutions, the present invention forms a collaborative working mechanism at multiple levels, including rule generation, route construction, flight execution, and rule presentation, providing a scalable and automated solution for airspace management in high-density operating environments.

[0059] The following further describes the implementation, working process, and advantages of specific embodiments of the present invention.

[0060] A method for route construction and flight rule visualization based on dynamic 3D digital commands includes the following steps: S01: Rule-based instruction refer to Figure 2 In this embodiment, the system first processes the rules based on the textual rules information such as flight regulations, airspace management regulations, airspace control notices and temporary management requirements issued by the airspace management department through a rule digitization parsing engine.

[0061] Specifically, the rule digitization parsing engine performs semantic parsing, keyword extraction, logical structure analysis, and parameter extraction on text rules. It structurally decomposes the implicit spatial constraints, temporal activation conditions, and behavioral constraints in the rules and encodes them into a unified format digital rule model. The generated digital instruction set includes at least admission rules, access rules, dynamic restriction rules, and environmental information rules, ultimately generating a three-dimensional digital instruction set containing spatial constraint parameters, temporal constraint parameters, and behavioral constraint parameters.

[0062] In this way, flight rules that originally relied on human understanding and memorization are transformed into digital instructions that machines can directly parse and process, providing standardized rule inputs for subsequent route construction and automatic execution, and forming a unified rule input foundation.

[0063] Furthermore, step S01 specifically includes: For each airspace grid cell, a set of digital flight rules corresponding to that grid is associated to achieve precise binding between the rules and specific spatial locations. Based on multi-source information such as weather changes, airspace control adjustments, and public security emergency needs, the rules of the grid cell are generated, updated, or revoked through a dynamic rule mapping module to achieve dynamic adjustment and real-time effectiveness of flight rules.

[0064] In the rule instruction process described in S01, the rule digitization parsing engine not only performs semantic parsing on the flight rule text, but also breaks down and marks the scope of application and effective conditions of the rules. For example, for rules with specific altitude restrictions, specific time windows, or applicable conditions for specific aircraft types, the system encodes the restrictions as altitude parameters, time parameters, and object parameters, respectively, and stores them as part of the three-dimensional digital instructions.

[0065] S02: Dynamic Road Construction refer to Figure 3 After the rules are formalized, the system dynamically constructs flight routes based on flight mission requirements. Specifically, when a user or the flight mission system requests a flight from origin A to destination B, the grid route construction module performs path calculations in the airspace grid model based on the digital instruction set generated by S01.

[0066] During the path calculation process, the system first performs rule matching on the airspace grid within the planned flight time period and filters out the passable grid cells that meet the current rule conditions. Then, based on the spatial connection relationship between the grids, the passable grids are linked in sequence to form a continuous grid sequence, thereby constructing a three-dimensional dynamic flight path that conforms to the rule constraints.

[0067] This step ensures that flight routes meet flight rule requirements during the generation stage, achieving "road construction based on rules." This ensures that flight routes are compliant from the generation stage, rather than being pre-set statically. Instead, they are dynamically generated in the airspace grid according to rule conditions, thus guaranteeing compliance during the generation stage and avoiding frequent corrections due to rule conflicts during flight.

[0068] Furthermore, step S02 specifically includes: Based on the spatial constraint instructions, speed limit instructions, and maneuver permission instructions specified in the three-dimensional digital instructions, path search and optimization are performed in the airspace grid to generate the optimal compliant route that meets the flight rule constraints. When the external environment or rule conditions change, the digital instructions of the affected grid are refreshed in real time, and the route is recalculated and adjusted simultaneously to ensure that the route always meets the latest rule requirements.

[0069] In the dynamic road construction process described in S02, when the grid route construction module performs path search, it does not only select paths based on spatial connectivity, but also uses three-dimensional digital commands as path filtering conditions for judgment.

[0070] Specifically, when a certain airspace grid has prohibited passage or additional restrictions during the planned flight time period, the grid will be marked as impassable or restricted, and thus automatically excluded or downgraded in priority during the route construction process.

[0071] This mechanism enables the route planning process to inherently possess rule-based constraints, avoiding rule verification after route generation and improving the efficiency and compliance of route generation at the system level.

[0072] S03: Visual Presentation refer to Figure 2 After the route is constructed, the system renders and displays the digital instructions of the route and the grid along the route through a visual interactive terminal.

[0073] Specifically, the visual interactive terminal can use an augmented reality (AR) interface or a 3D map interface to present digital instructions related to flight rules in an intuitive graphical way. This enables the restriction conditions that were originally implicit in the text rules to be expressed and presented in an intuitive 3D visualization. For example, "speed limit" or "altitude limit" instructions can be rendered as virtual electronic fences with clear boundaries, passable flight route areas can be rendered as continuous virtual air corridors, and speed or altitude restrictions can be marked graphically. This transforms flight rules from abstract descriptions into intuitive and perceptible three-dimensional expressions, achieving the effect of "understanding and flying clearly".

[0074] Through the above methods, operators or regulators can intuitively understand flight rules and route status, reducing the difficulty of understanding the rules.

[0075] Furthermore, step S03 specifically includes: By using augmented reality (AR) interfaces or 3D map interfaces, digital commands are presented in a three-dimensional manner, enabling aircraft operators or regulators to intuitively identify airspace restrictions and passable areas. Before an aircraft enters a specific airspace grid, the rules and commands for that grid are highlighted, and relevant information is presented only when necessary, thereby reducing information interference and improving the efficiency of rule execution.

[0076] During the visualization process described in S03, the visualization interactive terminal can present the content of the digital instructions in a hierarchical manner according to the user role or application scenario.

[0077] For example, in the aircraft operator's interface, the system focuses on displaying flight routes, restricted flight areas, and key rule prompts directly related to the current flight mission; while in the supervisor's interface, the system can simultaneously display the flight route distribution of multiple aircraft and the corresponding airspace rule status, thereby assisting in airspace situation monitoring.

[0078] The above-mentioned hierarchical display mechanism makes the visualization both intuitive and non-redundant, improving the efficiency of information utilization.

[0079] S04: Implement in accordance with regulations refer to Figure 3 and Figure 4 During the flight execution phase, the aircraft continuously subscribes to and obtains digital commands corresponding to its current airspace grid and the forward path grid from the central management system through onboard communication equipment.

[0080] (a) Example of rule change execution In a typical embodiment, the rule engine detects that a certain airspace grid (e.g., Grid_X) requires a temporary "detour" rule due to a sudden weather change. At this time, the system updates the digital instructions for the grid through the rule dynamic mapping module and pushes the updated correction instructions to all aircraft planning to enter the grid in real time, thereby completing the dynamic update and distribution of the rules.

[0081] (ii) Flight control closed-loop execution After receiving the correction command, the flight control system at the aircraft end uses the digital command as the flight control input parameter, automatically recalculates the avoidance path that meets the requirements of the rules, and performs flight actions such as deceleration, turning or altitude adjustment as needed to ensure that the flight process continues to meet the latest rule requirements.

[0082] In this way, a flight control closed loop with digital commands at its core is formed, enabling the rule execution process to be automated and real-time.

[0083] (III) Dynamic Expression Mechanism Before an aircraft is about to enter a specific airspace grid such as Grid_X, the system only highlights the specific flyaround or restriction instructions for that grid at necessary time points, and does not display them before the aircraft approaches the area, thereby effectively reducing information interference and improving the pertinence and execution efficiency of rule prompts.

[0084] During flight, the aircraft receives in real time the three-dimensional digital commands corresponding to its current location and the airspace grid it is about to enter through its onboard communication equipment. The dynamic guidance module monitors the flight status of the aircraft based on the digital commands and pushes corresponding correction commands to the aircraft when it detects deviations from the rules or changes in the rules.

[0085] Furthermore, step S04 specifically includes: The aircraft subscribes to and obtains digital flight rules related to its current position and predicted flight path from the central management system in real time through onboard communication equipment; the digital flight rules are used as input parameters of the flight control system, and the flight control system automatically adjusts the flight speed, heading or altitude according to the rule requirements, thereby realizing rule-based closed-loop control during the flight process.

[0086] During the rule-following process described in S04, the dynamic guidance module not only performs rule matching based on the aircraft's current position, but also combines the aircraft's heading, speed, and route planning results to predict and judge the airspace grid that the aircraft is about to enter.

[0087] When it is predicted that an aircraft will enter a restricted or rule-changed airspace grid during subsequent flight, the system can send a prompt or correction instruction to the aircraft in advance, thereby enabling the aircraft to adjust its flight status in advance and further improving flight safety and the smoothness of rule execution.

[0088] In actual operation, the rule digitization analysis engine can interact with external rule source systems to obtain the latest flight rules, airspace control notices, or temporary restriction information. Upon receiving a new rule, the engine parses the rule content, determines its scope of application and effective conditions, and generates or updates corresponding dynamic 3D digital instructions only for the affected airspace grid.

[0089] This mechanism enables targeted rule updates, avoids unnecessary rule recalculation across the entire spatial grid, and thus improves the overall system efficiency.

[0090] During flight, when the rule dynamic mapping module detects a change in the rules of a certain airspace grid, the system not only updates the dynamic 3D digital command corresponding to that grid, but also simultaneously triggers an impact assessment on the generated flight path.

[0091] If the assessment results indicate that the original route will conflict with the updated rules in subsequent flight phases, the grid route construction module will perform local replanning on the affected route segments, rather than completely recalculating the entire route. This will reduce the extent of route adjustments while ensuring rule compliance, and improve the continuity and smoothness of the flight process.

[0092] In scenarios where multiple aircraft operate simultaneously, each aircraft subscribes to dynamic, three-dimensional digital commands relevant to itself from the central management system based on its own flight mission and current position. Because the rules are bound on a grid basis, different aircraft, even in the same airspace area, can apply different digital commands depending on their altitude or time of day.

[0093] By employing the above methods, the system can provide differentiated rule guidance for multiple aircraft in high-density operation scenarios, avoiding rule conflicts and information redundancy, and improving overall airspace operation efficiency.

[0094] During the visualization process, the interactive visualization terminal can dynamically update the rendered flight paths and rules based on the real-time status of the aircraft. For example, when a flight path is adjusted due to rule changes, the system synchronously updates the shape and position of the virtual air corridor, enabling operators to perceive the flight path changes immediately.

[0095] The state synchronization mechanism ensures that the visualized results are consistent with the actual flight control logic, avoiding operational misjudgments caused by information asynchrony.

[0096] In the dynamic expression mechanism, the system can dynamically calculate the advance of the rule prompts based on the aircraft's speed and heading, and highlight the relevant rules only when the aircraft enters the rule's effective time window or spatial threshold range.

[0097] By controlling the timing of the prompts, the rules are prompted neither too early, causing information interference, nor too late, affecting flight decisions, thus achieving a balance between safety and operational burden.

[0098] In this invention, by constructing a rule-bearing unit based on an airspace grid, flight rules are refined from traditional global and abstract descriptions into digital instruction units that can be applied to specific spatial locations and time periods, giving flight rules the technical characteristics of being calculable, pushable, and executable.

[0099] The dynamic three-dimensional digital command is not a simple mapping of rule text, but a unified model of the spatial boundary conditions, time-effective conditions and flight action constraints contained in the flight rules, and binds them to the airspace grid and time dimension in the form of structured parameters, thereby realizing the accurate expression of flight rules in three-dimensional space and time axis.

[0100] Based on this, the present invention uses a grid route construction module to make the route generation process no longer independent of flight rules, but dynamically constructed in the airspace grid under rule constraints, so that the route is compliant at the generation stage, and reduces the temporary adjustments and manual intervention caused by rule conflicts during flight from a technical mechanism perspective.

[0101] Meanwhile, the present invention presents the dynamic three-dimensional digital instructions in the form of three-dimensional electronic fences, virtual air traffic corridors and graphical prompts through a visual interactive terminal, transforming flight rules that originally only existed in text or charts into intuitively perceptible spatial objects, thereby reducing the threshold for understanding the rules and improving the consistency and accuracy of flight rule execution.

[0102] Furthermore, this invention uses a dynamic guidance module to continuously monitor the aircraft's status during flight execution and compare the aircraft's status with the applicable dynamic three-dimensional digital commands in real time. When a deviation from the rules or a change in the rules is detected, a correction command is promptly pushed to the aircraft, thereby constructing a flight control closed loop with digital rules at its core, and realizing the dynamic execution and real-time correction of flight rules.

[0103] Through the above technical solution, this invention realizes the transformation of flight rules from "static release - manual interpretation - post-event correction" to "dynamic command - automatic guidance - pre-event constraint", providing reliable technical support for airspace management in high-density, automated flight scenarios.

[0104] During system operation, to ensure consistency between the rule parsing results and the actual execution, the system can perform consistency verification on the generated dynamic three-dimensional digital instructions after the rules are instructed.

[0105] The consistency verification may include, but is not limited to: rule parameter integrity checks, rule conflict detection, and judgment of the reasonableness of rule validity conditions. This verification mechanism prevents the aircraft from executing incorrect commands due to rule parsing anomalies or missing data, thereby improving the reliability of system operation.

[0106] In actual operation, flight rules may be frequently updated for various reasons. To address this, the system can introduce version identifiers for dynamic 3D digital commands, generating new command versions when rules are updated, and retaining historical versions for traceability and analysis.

[0107] During flight, the aircraft always uses the latest and most effective version of digital commands as the basis for execution, while historical versions can be used for flight review, accident analysis, or rule optimization, thereby improving the auditability of airspace management.

[0108] In certain abnormal situations, such as brief communication interruptions or temporary delays in rule update information synchronization, the aircraft can continue to perform flight missions based on cached dynamic stereo digital commands.

[0109] After communication is restored, the system will automatically compare the rule version cached on the aircraft with the latest rule version in the central system, and push the necessary correction instructions when there are differences, so as to ensure that the flight process eventually returns to a rule-compliant state.

[0110] This approach improves the system's robustness in complex operating environments.

[0111] The system described in this invention can work collaboratively with existing flight management systems, airspace monitoring systems, or emergency command systems. Through standardized interfaces, different systems can share rule status and flight path information based on dynamic three-dimensional digital commands, thereby forming a unified airspace operational status.

[0112] In this collaborative application, the dynamic three-dimensional digital instructions provided by this invention serve as a unified expression of rules, reducing the integration complexity between multiple systems.

[0113] In terms of system architecture, the present invention also provides a flight path construction and visualization flight rule system based on dynamic three-dimensional digital commands. The system includes a rule digitization parsing engine, a grid flight path construction module, a visualization interactive terminal and a dynamic guidance module, and works collaboratively through a digital rule engine, a communication and sensing network and an aircraft-side adaptation module, thereby supporting the complete implementation of the method.

[0114] It should be noted that the specific implementation of the rule digitization parsing engine, grid route construction module, visual interactive terminal, and dynamic guidance module described in this invention can be adjusted according to actual application requirements.

[0115] For example, the rule digitization parsing engine can be deployed on a centralized server or in a distributed computing environment; the visual interactive terminal can be a desktop terminal, a mobile terminal, or an airborne display terminal; the dynamic guidance module can be deeply integrated with the flight control system or interact through an interface. Any equivalent substitutions made without departing from the technical spirit of this invention should be considered to fall within the protection scope of this invention.

[0116] As can be seen from the above implementation methods, the present invention constructs a flight rule management and execution system with dynamic three-dimensional digital instructions as its core, so that flight rules exist in a unified digital form at each stage of generation, display and execution.

[0117] This system is not only applicable to rule-based guidance for a single aircraft, but can also be extended to complex scenarios where multiple aircraft operate in parallel, providing a scalable technical foundation for future high-density low-altitude operations.

[0118] Through the above implementation methods, the present invention realizes a complete closed loop from rule parsing, route construction, visualization presentation to flight execution, enabling flight rules to be automatically understood and executed by the aircraft in the form of digital instructions, significantly reducing the need for human intervention and improving flight safety and operational efficiency in complex airspace environments.

Its core lies in transforming static airspace into a dynamic interactive environment, constructing a dynamic flight route network through airspace grid technology, and parsing flight rules, traditionally presented in text and chart form, into dynamic three-dimensional digital instructions. By binding rule logic to a spatiotemporal grid, the system generates machine-readable and human-visually-readable guidance instructions, enabling aircraft to obtain compliant paths in real time during mission execution, thus achieving the effect of "understandable and clear-flying." This invention realizes the dynamic expression and orderly management of airspace rules, effectively solving problems such as difficulty in executing flight rules and significant ambiguity in complex environments, providing strong support for automated airspace control under high-density operation.

[0120] Compared with the prior art, the present invention has at least the following significant advantages: Dynamic: By binding rules with airspace grids and time dimensions, flight rules can be updated in real time and take effect immediately, enabling airspace management to respond quickly to dynamic situations such as weather changes and emergencies.
