Description

Technical Field

[0001] The present invention relates to the technical field of intelligent operation and management of uncontrolled airspace, and in particular to a method and system for intelligent operation and supervision of low-altitude airspace at the city level. Background Art

[0002] On December 21, 2023, the Civil Aviation Administration of China issued the "National Airspace Basic Classification Method" to regulate the demarcation, management and use of my country's airspace. According to factors such as aircraft flight rules and performance requirements, airspace environment, and air traffic control service content, the airspace is divided into seven categories: A, B, C, D, E, G, and W. Among them, A, B, C, D, and E are controlled airspace, and G (below 120 meters) and W (below 300 meters) are uncontrolled airspace.

[0003] Urban low-altitude aircraft refer to aircraft that fly at low altitudes in urban environments, involving a variety of application scenarios, including but not limited to urban air traffic, logistics transportation, medical rescue, and tourism. These aircraft not only improve urban traffic efficiency, but also reduce ground traffic congestion and enhance the overall travel experience.

[0004] In actual applications, urban low-altitude aircraft are not subject to strict supervision like aircraft in controlled areas. Generally, they only need to register on the corresponding platform and go through some relatively simple information review process, and they can operate without the need to submit a flight plan for approval in advance. The above characteristics of urban low-altitude aircraft give operators greater flexibility, but also bring risks, especially the short flight time and distance of urban low-altitude aircraft, and the high flight frequency, so there are often multiple flights in the same airspace at the same time. Therefore, in the current uncontrolled airspace, their takeoff and landing are disorderly, threatening the safety of urban operations.

[0005] Based on this, a more reliable regulatory solution is needed for low-altitude aircraft in cities. Summary of the invention

[0006] The purpose of the present invention is to provide a city-level low-altitude airspace intelligent operation supervision method and system to solve the problem of lack of effective supervision of existing urban low-altitude aircraft and realize unified supervision of aircraft in uncontrolled airspace.

[0007] The embodiment of the present invention is implemented by the following technical solution: A city-level low-altitude airspace intelligent operation supervision method comprises the following steps:

[0008] receiving mission data indicating a flight plan for an aircraft, wherein the flight plan includes a planned flight time and a planned route;

[0009] Determine whether the airspace capacity corresponding to the planned flight time can meet the flight needs of the operator, and if not, generate first information instructing to re-plan the flight plan and feed it back to the operator, wherein the first information includes a recommended flight time and a recommended route;

[0010] receiving dynamic data indicating flight paths of aircraft within the airspace; and

[0011] Based on the flight route, it is determined whether the aircraft deviates from the planned route. If so, second information indicating a return route is generated and fed back to the aircraft.

[0012] According to a preferred embodiment, the first information indicating re-planning of the flight plan also includes first micro-meteorological information corresponding to the recommended flight time and the recommended route.

[0013] According to a preferred embodiment, the method further comprises, if the airspace capacity corresponding to the planned flight time can meet the flight demand of the operator, generating third information instructing the aircraft to execute the flight plan and feeding it back to the operator.

[0014] According to a preferred embodiment, the third information instructing the aircraft to execute the flight plan also includes second micro-meteorological information corresponding to the planned flight time and the planned route.

[0015] According to a preferred embodiment, the dynamic data indicating the flight routes of aircraft in the airspace include aircraft flight dynamic data regularly reported by the aircraft and aircraft status data sensed by sensing equipment.

[0016] According to a preferred embodiment, the aircraft flight dynamics data regularly reported by the aircraft at least includes latitude and longitude, flight altitude, flight speed and route weather information.

[0017] According to a preferred embodiment, before determining whether the aircraft deviates from the planned route based on the flight route, the method further includes determining whether the aircraft regularly reports aircraft flight dynamic data, and if not, generating fourth information indicating that the registered aircraft reports flight dynamic data and feeding it back to the aircraft; and

[0018] Fifth information indicating that interference is to be performed on the unregistered aircraft is generated and fed back to the interference device.

[0019] According to a preferred embodiment, after generating the second information indicating the return route and feeding it back to the aircraft, the method further includes determining whether the aircraft responds, and if not, generating the fifth information indicating the execution of manual processing on the first aircraft and feeding it back to the supervisor, the first aircraft being the aircraft that did not respond to the second information;

[0020] If so, sixth information instructing to perform manual processing on the second aircraft is generated and fed back to the platform supervisor, where the second aircraft is the aircraft that has responded to the second information but still deviates from the planned route.

[0021] According to a preferred embodiment, after generating fifth information indicating manual processing of the first aircraft or sixth information indicating manual processing of the second aircraft and feeding it back to the platform supervisor, the method also includes determining whether the aircraft is abnormal, and if so, generating seventh information indicating interference with the abnormal aircraft and feeding it back to the interference device.

[0022] The present invention also provides a city-level low-altitude airspace intelligent operation and supervision system, which is applied to the method described above, and the system includes: a data asset layer, which is used to store collected basic data, flight dynamics data and aircraft status data; a basic support layer, which is used to call the basic data, flight dynamics data and aircraft status data stored in the data asset layer; a platform management layer, which is used to obtain basic data, flight dynamics data and aircraft status data through the basic support layer, and construct a digital airspace based on the basic data, flight dynamics data and aircraft status data; a platform user layer, which is used to display the basic data, flight dynamics data, aircraft status data and digital airspace to users, and interact with users based on the basic data, flight dynamics data, aircraft status data and digital airspace.

[0025] Figure 2 This is an architectural diagram of the city-level low-altitude airspace intelligent operation and supervision system provided in Example 2 of the present invention. DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0027] Example 1

[0028] See also Figure 1 As shown, Figure 1 This is a flow chart of the city-level low-altitude airspace intelligent operation and supervision method provided by an embodiment of the present invention. Figure 1 As shown, the method comprises the following steps:

[0029] The operator reports the flight mission, and the mission data is used to indicate the operator's flight plan; the flight plan specifically includes the basic data of the aircraft, the aircraft's planned flight time, the aircraft's planned route, etc.

[0030] The basic data of the aircraft include the aircraft number, mission number and mission type, the planned flight time of the aircraft includes the planned mission start time and the planned mission end time, and the planned route of the aircraft includes the planned take-off point, planned landing point and planned flight route.

[0031] The platform receives flight missions reported by operators and analyzes the planned flight time and planned routes of the aircraft; based on the analysis results, it determines whether the airspace capacity corresponding to the planned flight time can meet the flight needs of the planned route.

[0032] In a possible implementation of this embodiment, if the airspace capacity corresponding to the planned flight time cannot meet the flight needs of the operator, the platform generates first information instructing the operator to re-plan the flight plan and feeds it back to the operator; wherein the first information includes the recommended flight time, the recommended route, and the first micro-meteorological information corresponding to the recommended flight time and the recommended route. If the airspace capacity corresponding to the planned flight time can meet the flight needs of the operator or the operator adopts the recommended flight time and the recommended route provided by the platform, and reports the recommended flight time recommended by the platform as its flight plan with the recommended route, the platform generates third information instructing the aircraft to execute the flight plan and feeds it back to the operator, and the operator can approach and perform the mission according to the reported flight plan; wherein the third information instructing the aircraft to execute the flight plan also includes the second micro-meteorological information corresponding to the planned flight time and the planned route.

[0033] In this embodiment, by introducing micro-meteorological data to evaluate the impact of meteorological factors such as airspace wind speed, temperature, and humidity on flight, it is helpful to adjust the flight plan in time under different meteorological conditions, ensure the safety and stability of aircraft flight, and reduce accidents and mission failures caused by bad weather.

[0034] After the aircraft approaches, the platform receives dynamic data indicating the flight route of the aircraft in the indicated airspace; the dynamic data indicating the flight route of the aircraft in the indicated airspace includes the aircraft flight dynamic data regularly reported by the aircraft and the aircraft status data sensed by the sensing equipment; in this embodiment, the aircraft reports the aircraft flight dynamic data every 2 seconds; the aircraft flight dynamic data includes the aircraft number, mission number, longitude and latitude, flight altitude, flight speed and route weather information, etc.

[0035] Furthermore, the platform determines whether the aircraft regularly reports the aircraft's flight dynamics data. If the aircraft does not regularly report the aircraft's flight dynamics data, it further determines whether the aircraft has been registered. If it is determined that the aircraft is not registered, the fifth information instructing the unregistered aircraft to be interfered with is generated and fed back to the interference device, and the aircraft is forced to land. If it is determined that the aircraft is registered, the fourth information instructing the registered aircraft to report the flight dynamics data is generated and fed back to the aircraft, requiring the aircraft to regularly report the flight dynamics data, and marking the aircraft, recording an illegal operation, and performing corresponding processing after its task is completed.

[0036] In this embodiment, for an aircraft that regularly reports aircraft flight dynamic data, the platform further determines whether the aircraft deviates from the planned route based on the flight route.

[0037] In a possible implementation of this embodiment, if the aircraft deviates from the planned route, the platform generates a second message indicating the return route and feeds it back to the aircraft, notifying the aircraft that it has deviated from the planned route and requiring it to return to the route; further, after generating the second message indicating the return route and feeding it back to the aircraft, the platform needs to determine whether the aircraft responds. If the aircraft does not respond to the second message, the platform generates a fifth message indicating that manual processing is to be performed on the aircraft and feeds it back to the supervisor. If the aircraft responds to the second message and determines that it has returned to the planned route, the aircraft returns to the normal task execution process; for aircraft that respond but still deviate from the planned route, the platform generates a sixth message indicating that manual processing is to be performed on the aircraft and feeds it back to the platform supervisor.

[0038] Furthermore, after generating fifth information indicating manual processing of the aircraft or sixth information indicating manual processing of the aircraft and feeding it back to the platform supervisor, the method further includes determining whether the aircraft is abnormal. If the aircraft is determined to be abnormal, seventh information indicating interference with the abnormal aircraft is generated and fed back to the interference device to perform forced landing of the aircraft. If it is determined that the aircraft is not abnormal and it is determined that it has returned to the planned route, the aircraft returns to the normal task execution process.

[0039] When the aircraft flies normally to the planned landing point, the planned landing point is vacant at this time, and the aircraft can dock by itself. In a possible implementation of this embodiment, when the aircraft deviates from the route midway, since its planned flight time has changed, it is impossible to determine whether its planned landing point is vacant at this time. At this time, the aircraft needs to initiate a landing request. When the platform receives the landing request initiated by the aircraft, it determines whether its planned landing point is vacant. If it is vacant, it sends a landing instruction to the aircraft. Otherwise, it sends a waiting instruction to the aircraft or sends a recommended landing point. No further details are given here.

[0040] In summary, the embodiments of the present invention provide digital services for airspace and flight through the perception and acquisition of aircraft basic data, aircraft flight dynamic data, and aircraft status data, which can achieve unified supervision of aircraft and maintain the safety of urban operations.
