Description

Technical Field

[0001] The present invention relates to the field of low-altitude economic management, and in particular to an aircraft work management platform and method suitable for low-altitude economy. Background Art

[0002] Since the application scenarios of low-altitude economy cover a very wide range, such as manned air traffic, logistics transportation, emergency rescue, agricultural and forestry plant protection, tourism and sightseeing, and personal aerial photography, there will inevitably be a large number of low-altitude aircraft working at the same time in the future. If the management and planning of aircraft work are not carried out in advance, it will inevitably lead to chaos in the entire air network and even safety hazards. Summary of the invention

[0003] In view of the shortcomings of the prior art, the present invention proposes an aircraft work management platform and method suitable for the low-altitude economy, which can manage the flight work of low-altitude aircraft in different application scenarios, ensure the orderly, safe and efficient operation of a large number of low-altitude aircraft, and help promote the development of the low-altitude economy.

[0004] The specific technical solutions are as follows:

[0005] An aircraft work management platform suitable for low-altitude economy, comprising: a cloud database, a master control center, and a terminal low-altitude aircraft; the cloud database comprises: a low-altitude aircraft information management database, a three-dimensional terrain map database, and a low-altitude aircraft real-time dynamic database;

[0006] The master control center is used to perform path planning based on the work task request information sent by the terminal low-altitude aircraft in combination with the real-time airspace information, and the generated flight plan information is sent to the terminal low-altitude aircraft; the real-time airspace information is obtained based on the three-dimensional topographic map database and the real-time dynamic database of low-altitude aircraft; the flight plan information includes the flight altitude range and the optimal path, and the optimal path is the shortest distance path that meets two conditions at the same time, and the two conditions are: aircraft with high authority levels are given priority and the aircraft safety boundaries do not overlap.

[0007] Furthermore, the work task request information includes: work task type, aircraft take-off and landing position, load weight, and task time.

[0008] Furthermore, the low-altitude aircraft information management database is classified and stored according to the tag information of the low-altitude aircraft, and the tag information includes: work task type, model, load, flight altitude, flight speed, and authority level;

[0009] The types of work tasks include: manned air traffic, large-scale transportation, small-scale logistics, emergency rescue, agricultural and forestry plant protection, tourism and sightseeing, and personal aerial photography.

[0010] Furthermore, the flight altitude range of the terminal low-altitude aircraft is 0 to 3000 meters, with one interval set at every 500 meters in altitude, for a total of 6 intervals; the flight altitude intervals allocated to terminal low-altitude aircraft of different work mission types are set according to requirements.

[0011] Furthermore, the safety boundary setting principle of the terminal low-altitude aircraft is related to the work task type of the terminal low-altitude aircraft. No safety boundary is set for small-scale logistics, emergency rescue, agricultural and forestry plant protection, and personal aerial photography. The safety boundary space for manned air traffic, large-scale transportation, and tourism is a rectangular space formed by its corresponding front, back, left, right, top, and bottom boundaries.

[0015] S3: The master control center generates flight plan information based on the flight mission and the real-time information of the current airspace through the built-in path planning intelligent algorithm and sends it to the terminal low-altitude aircraft; the flight plan information includes: flight altitude range and optimal path.

[0016] S4: The terminal low-altitude aircraft performs flight work according to the flight plan information sent by the master control center.

[0017] S5: After the terminal low-altitude aircraft completes all flight tasks, it sends a mission completion message to the main control center, and the main control center disconnects from the terminal low-altitude aircraft.

[0018] The beneficial effects of the present invention are:

BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figure 1 It is a structural schematic diagram of an aircraft work management platform suitable for low-altitude economy in an embodiment of the present invention. DETAILED DESCRIPTION

[0021] The present invention will be described in detail below according to the accompanying drawings and preferred embodiments, and the purpose and effect of the present invention will become more clear. The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] like Figure 1 As shown, a work management platform for low-altitude economic aircraft includes: a cloud database, a master control center, and a terminal low-altitude aircraft. The cloud database includes: a low-altitude aircraft information management database, a three-dimensional terrain map database, and a low-altitude aircraft real-time dynamic database. The low-altitude economic altitude range applicable to the terminal low-altitude aircraft is 0 to 3000m.

[0023] The master control center is used to generate flight plan information and send it to the terminal low-altitude aircraft based on the work mission request information sent by the terminal low-altitude aircraft, combined with the aircraft information in the low-altitude aircraft information management database, the three-dimensional terrain map database and the real-time dynamic database of the low-altitude aircraft. The intelligent path planning algorithm built into the master control center generates the flight plan information. The master control center always maintains a real-time connection with the terminal low-altitude aircraft during the operation of the low-altitude aircraft, and has the function of temporarily adjusting the flight plan of the terminal low-altitude aircraft. The work mission request information includes: work mission type, aircraft take-off and landing position, load weight, mission time, etc.

[0024] The low-altitude aircraft information management database is classified and stored according to the tag information of the low-altitude aircraft. The tag information includes: work task type, model, load, flight altitude, flight speed, authority level, etc. Typical low-altitude aircraft tag information examples are shown in Table 1. Work task types include: manned air traffic, large-scale transportation, small-scale logistics, emergency rescue, agricultural and forestry plant protection, tourism, and personal aerial photography. Preferably, the authority level includes four levels from high to low, including S, A, B, and C, which match the work task type, as shown in Table 2. The low-altitude aircraft real-time dynamic database stores the real-time status and location information of the terminal low-altitude aircraft, and is connected to the low-altitude aircraft in real time through the main control center during the operation of the terminal low-altitude aircraft.

[0028]

[0029] The path planning intelligent algorithm built into the master control center generates flight plan information based on the work mission request information, aircraft information, and airspace real-time information of the low-altitude aircraft. The flight plan information includes the flight altitude interval and the optimal path. The flight altitude interval is the main working interval of the terminal low-altitude aircraft. Under normal circumstances, the terminal low-altitude aircraft is only allowed to perform flight work tasks within the assigned flight altitude interval. The allocation of the flight altitude interval is mainly based on the work mission type of the terminal low-altitude aircraft. Preferably, the altitude range is 0 to 3000 meters, and one interval is set at every 500 meters, with a total of 6 intervals. The flight altitude intervals allocated to terminal low-altitude aircraft with different work mission types are shown in Table 3. The optimal path is the shortest distance path that satisfies the conditions that terminal low-altitude aircraft with high authority levels are given priority and the safety boundaries of each aircraft do not overlap; the aircraft safety boundary is a space set up to ensure the safety of terminal low-altitude aircraft. No other terminal low-altitude aircraft are allowed to enter this space. The safety boundary setting principle is related to the work task type of the terminal low-altitude aircraft, as shown in Table 4. Among them, small-scale logistics, emergency rescue, agricultural and forestry plant protection, and personal aerial photography do not have safety boundaries. The safety boundary space for manned air traffic, large-scale transportation, and tourism is a rectangular space formed by the corresponding front, back, left, right, top, and bottom boundaries; preferably, T1 is set to 60s, T2 is set to 30s, and T3 is set to 10s.

[0034] Based on the above-mentioned aircraft work management platform applicable to low-altitude economy, this embodiment also proposes an aircraft work management method applicable to low-altitude economy, which specifically includes the following steps:

[0035] S1: The terminal low-altitude aircraft sends an aircraft work task request to the main control center.

If it has been stored, the work task request is accepted. Otherwise, the request is returned and the terminal low-altitude aircraft is required to register and complete the information storage.

[0036] S2: After the main control center confirms that it has accepted the terminal low-altitude aircraft work task request, it maintains connection with the terminal low-altitude aircraft, synchronously retrieves all aircraft information of the terminal low-altitude aircraft from the low-altitude aircraft information management database, and accesses the low-altitude aircraft real-time dynamic database and three-dimensional terrain map database to obtain the current airspace real-time information generated by them.

[0037] S3: The control center generates flight plan information based on the aircraft's work mission request information, combined with aircraft information and real-time information of the current airspace, and sends it to the terminal low-altitude aircraft through the built-in path planning intelligent algorithm. The flight plan information includes: flight altitude range and optimal path. The optimal path is the shortest distance path that satisfies the conditions that aircraft with higher authority levels are given priority and the safety boundaries of each aircraft do not overlap.

[0038] S4: The terminal low-altitude aircraft performs flight operations according to the flight plan information sent by the main control center. During the flight operation, the main control center transmits real-time status and position information to the real-time dynamic database of the low-altitude aircraft, and keeps receiving real-time flight plan information changes from the main control center.

[0039] S5: After the terminal low-altitude aircraft completes all flight tasks, it sends a mission completion message to the main control center, and the main control center disconnects from the terminal low-altitude aircraft.
