Description

Technical Field

[0001] This invention relates to the field of traffic assistance technology, and in particular to an urban air traffic planning and design assistance system. Background Technology

[0002] Urban air mobility (UAM) refers to safe and efficient manned / unmanned (air) transportation systems used for passenger or freight transport in cities. With rapid urbanization, land resources are becoming scarce, and ground traffic is increasingly congested, necessitating the development and utilization of air resources. UAM primarily utilizes low-altitude airspace, is unaffected by complex urban terrain, and can achieve point-to-point flights, offering convenience, speed, and efficiency. Planning and constructing UAM can effectively develop and utilize urban low-altitude resources, creating a comprehensive three-dimensional transportation system integrating air, ground, and underground transport.

[0003] The development of the urban air traffic planning and design support system aims to solve practical problems and meet the actual needs of urban traffic planning. Through this system, flight paths, airspace allocation, and takeoff and landing point layouts for urban air traffic can be scientifically and rationally planned, improving the overall efficiency and safety of the urban transportation system.

[0004] However, the current urban air traffic planning and design capabilities are not mature enough, and the existing environment cannot be fully considered for reasonable design. The planning and design schemes are too inefficient. Therefore, an auxiliary system for urban air traffic planning and design is provided. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an urban air traffic planning and design auxiliary system, which solves the problems of insufficient maturity in current urban air traffic planning and design capabilities, inability to fully consider the existing environment for reasonable design, and overly inefficient planning and design schemes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A system for assisting urban air traffic planning and design includes a system module assembly. The system module assembly comprises an information model module, a basic data module, a database, an information acquisition module, and an airspace design module. The airspace design module includes an airspace planning module, a route design module, and an aircraft performance analysis module. The airspace design module is connected to the information acquisition module and the database, and is also connected to a design verification module. The information acquisition module collects urban traffic information and geographic information. Then, based on the cooperation of the information model module, the basic data module, and the aircraft performance analysis module, it establishes vertical takeoff and landing (VTOL) and general aviation aircraft models. The performance analysis database includes an information acquisition module connected to an interface module, which in turn is connected to an information model module. The information model module is connected to a mechanism rule verification module. When designing air routes, the airspace design module first generates a topology map of the air route network structure, then obtains preset indicators for each air route node, and selects air route nodes whose rankings meet preset conditions as air route nodes for the proposed traffic construction. Initial traffic is then constructed at each air route node in a proportional manner to obtain the initial urban air traffic design scheme. The ground design module includes a take-off and landing site module, a support facility module, and an ancillary facility module.

[0007] Furthermore, the information acquisition module includes an electromagnetic module, which detects electromagnetic information in the environment and uploads it to the information acquisition module.

[0008] Based on the aforementioned scheme, the airspace planning module and the route design module are connected to an airspace management module, which includes a supervision and management module and a dynamic allocation module.

[0009] As a further embodiment of the present invention, the airspace management module is connected to a collaborative operation module and a safety supervision module. The collaborative operation module manages the flight activities of aircraft, collects information and intelligence, and makes emergency rescue responses. The safety supervision module mainly supervises low-altitude investigations, enterprise personnel, and aircraft.

[0010] Furthermore, the airspace management module also includes an infrastructure management module and a landing verification module.

[0011] Based on the aforementioned solution, the system module assembly includes a visualization module, which displays the nature and hierarchical classification of airspace, the planning and design of air routes, and the planning and construction of ground facilities and other infrastructure.

[0012] As a further aspect of the present invention, after obtaining the initial urban air traffic design scheme, the objective functions are to maximize the overall airway network capacity efficiency and minimize the overall airway network transportation cost. The constraints are flight altitude constraint, minimum path segment length constraint, maximum turning angle constraint, maximum climb angle constraint, maximum range constraint, and maximum takeoff mass constraint, and a multi-objective function optimization model for urban air traffic is constructed.

[0013] Furthermore, the system module assembly includes a calculation module, which solves for the optimal urban air traffic design scheme based on the initial urban air traffic design scheme and the urban air traffic multi-objective function optimization model.

[0014] The beneficial effects of this invention are as follows: 1. This invention can assess airspace effectiveness, low-altitude capacity, optimize selectable routes and tracks and dynamic airspace allocation, detect and analyze air conflicts and resolve conflicts, plan and design vertical take-off and landing, analyze the coverage of communication, navigation and surveillance signals, meteorological conditions and electromagnetic environment around the site, and plan communication, navigation, surveillance and safety meteorological settings.

[0015] 2. The interface module in this invention can connect with the operating enterprise and provincial and municipal flight service management platforms to realize digital simulation of operation management such as airspace, collaboration, safety supervision and infrastructure. The visualization display module facilitates real-time understanding of aircraft operation status, airspace, air routes and the practical status of ground facilities and weather conditions.

[0016] 3. This invention constructs a multi-objective function optimization model for urban air traffic, and based on the initial urban air traffic design scheme, adopts heuristic algorithms such as genetic algorithms to solve the optimization model and obtain the optimal urban air traffic design scheme.

[0017] 4. By setting up the airspace design module, we can realize intelligent design methods, digital design concepts, standardized design construction methods, and visualize design results, thereby improving the feasibility of air traffic planning schemes. Attached Figure Description
