[0034] It should be further explained that the surveying and mapping equipment includes multiple surveying and mapping cameras 6 and multiple surveying and mapping laser radars 7. The multiple surveying and mapping cameras 6 are respectively installed at the bottom of the platform frame 1 and the bottom of the multiple sub-body UAVs 2.

[0035] The electromagnet 11, battery, power storage body, first servo motor 22, second servo motor 23, third servo motor 25, Beidou navigation terminal, wireless network transmitting terminal, altitude sensor and satellite communication terminal in this embodiment are all conventional equipment purchased on the market and known to those skilled in the art. In the present invention, we only use them and do not improve their structure and function. For those skilled in the art, their setting method, installation method and electrical connection method only need to be debugged according to the requirements of their instruction manual, and will not be described in detail here.

[0036] To sum up, the working principle of the ultra-long-distance flying surveying and mapping platform for geographic surveying and mapping is that when in use, the ultra-long-distance flying surveying and mapping platform for geographic surveying and mapping is first transported to the vicinity of the geographic surveying and mapping. During the transportation process, the lift gas in the airbag 3 is discharged for the convenience of transportation. After being transported to the vicinity of the geographic surveying and mapping, the power condition of the battery is first detected. When the power in the battery is low, the battery should be charged first, and then the airbag 3 is filled with lift gas again. The lift gas should be a safer gas with a smaller density than air. During the filling of the airbag 3, the platform frame 1 should be tied or hung relative to the ground. The filling volume of the lift gas should be matched and selected according to the required lift buoyancy. After the lift gas is filled, the electromagnet 11, the battery, the battery, the first servo motor 22, and the second servo motor 23. After the third servo motor 25, Beidou navigation terminal, wireless network transmitting terminal, altitude sensor and satellite communication terminal are powered on, tested and adjusted, the binding or hanging effect of the platform frame 1 relative to the ground can be invalidated. Since the lifting gas can provide a certain buoyancy for the platform frame 1, the ultra-long-distance flight surveying and mapping platform for geographic surveying and mapping will rise relative to the ground in a free state and achieve lift-off. In the lift-off state, the altitude adjustment wing installed in the central circular hole cavity works to realize the auxiliary application of lift force and downforce of the platform frame 1, that is, the forward and reverse control of the flying wing 26 in the altitude adjustment wing realizes the lift force and downforce of the platform frame 1, thereby achieving the control of the lift height of the platform frame 1. At the same time, during the operation, the two auxiliary adjustment wings will also perform auxiliary adjustment according to the specific situation of the platform frame 1, such as the attached Figure 1 As shown in FIG. 1 , when the flying wing 26 in the auxiliary regulating wing is parallel to the platform frame 1 as a whole, the flying wing 26 can also provide lift force or down force for the platform frame 1 by controlling the rotation direction, as shown in FIG. Fig. 9 As shown, under the working control of the first servo motor 22, the upper and lower swing frames 20 are rotated out of the side mounting cavity, and under the working control of the second servo motor 23, the rotating swing frame 21 is rotated relative to the upper and lower swing frames 20. In this state, the flying wing 26 in the auxiliary regulating wing rotates again to realize the correction adjustment of the travel direction of the platform frame 1. Moreover, if only the first servo motor 22 works to control the upper and lower swing frames 20 to rotate out in the corresponding side mounting cavity, and the second servo motor 23 maintains the original relative position of the rotating swing frame 21 relative to the upper and lower swing frames 20, in this state, the flying wing 26 in the auxiliary regulating wing rotates to control the platform frame 1 to form a forward or backward flight.

[0037] Further, as attached Fig.10 The figure shows the operation route of the long-distance flight surveying and mapping platform used for geographical surveying and mapping. Fig.10 The circular track at the inner middle position is the motion track of the platform frame 1. Fig.10The U-shaped tracks on both sides are the running tracks of multiple sub-drones 2. Since the overall structure of the platform frame 1 is huge, the storage battery that can be matched in the platform frame 1 is also larger. After the sub-drone 2 is mounted relative to the platform frame 1, the storage battery in the platform frame 1 will charge the battery in the sub-drone 2. The release process of the sub-drone 2 relative to the platform frame 1 is that the corresponding electromagnet 11 is energized to generate a magnetic field, and the electromagnetic field and the corresponding permanent magnet block 10 produce mutual magnetic attraction to compress the elastic spring 9 between the two. The elastic spring 9 is compressed, causing the limit frame 8 connected to the elastic spring 9 to move in position in the mounting tube 4. After the limit frame 8 that has moved in position withdraws from the inserted limit slot 12, the sub-drone 2 will be relative to the platform frame After the sub-drone 2 is separated from the platform frame 1, the electromagnet 11 is powered off, and the separated sub-drone 2 runs in a U-shaped trajectory, while the platform frame 1 continues to move forward and releases the sub-drone 2 again after flying an equal distance, until all the sub-drones 2 are released, and the platform frame 1 forms a return flight path. With the release of the sub-drones 2, the load of the platform frame 1 will gradually decrease. In order to keep the heights of the sub-drones 2 released one after another consistent, the height adjustment wing works to maintain the height of the platform frame 1. After the sub-drone 2 is completely released, the speed of the flying wing 26 in the height adjustment wing is reduced or stopped, so that the height of the platform frame 1 is increased and the platform frame is realized under the action of the auxiliary adjustment wing. 1's return flight movement, after the platform frame 1 returns to the position near the initial release of the daughter UAV 2, the height adjustment wing works to achieve the downward pressure of the flight height of the platform frame 1, so as to achieve the height matching with the released daughter UAV 2, to meet the daughter UAV 2 after the U-shaped trajectory is completed, the electromagnet 11 is energized again to form a magnetic attraction with the permanent magnet block 10 to facilitate the mounting rod 5 on the daughter UAV 2 to be inserted into the mounting tube 4 again, and the daughter UAV 2 will insert the mounting rod 5 into the mounting tube 4 after the position matching is formed relative to the platform frame 1, and when the pressure sensor 13 contacts the push rod 14 and forms a certain pressure value, the electromagnet 11 is de-energized, and the limit frame 8 interacts with the limit slot 12 under the action of the elastic spring 9 to achieve the relative mounting of the mounting rod 5 The connection and positioning of the mounting tube 4 into which it is inserted is achieved, so that the sub-UAV 2 can be mounted again relative to the platform frame 1. After the limiting frame 8 is inserted relative to the limiting groove 12, the corresponding first conductor block 15 and the second conductor block 16 are respectively in contact with each other relative to the first conductor ring 17 and the second conductor ring 18, so that the electrical connection between the accumulator and the battery is achieved, so that the accumulator charges the battery to prepare for the sub-UAV 2 to fly again. After all the sub-UAVs 2 are recovered relative to the platform frame 1, a single working cycle of the ultra-long-distance flight mapping platform for geographic surveying and mapping is achieved, and then the platform frame 1 continues to fly forward until it passes through the area surveyed and mapped by the previous working cycle, and the sub-UAV 2 is released again.Start the next working cycle, and realize long-distance flight mapping through the sequential work of multiple working cycles. The information mapped by the mapping equipment can be stored in the storage module and can also be transmitted through the satellite communication terminal. Considering the storage space of the storage module, when mapping a small area, the mapping information is preferably stored in the storage module, and when mapping a large area, the mapping information is preferably transmitted through the satellite communication terminal. The mapping equipment only realizes the collection of actual information. For the subsequent processing of the collected information, other equipment and methods are required to assist in the realization.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

A first servo motor (22) is installed in the side installation cavity, and the two side installation cavities are each installed with the two first servo motors (22), the two first servo motors (22) are respectively used for rotation control of the two upper and lower swing frames (20), the two rotating swing frames (21) are respectively rotatably connected in the two upper and lower swing frames (20), the two upper and lower swing frames (20) are each installed with a second servo motor (23), the output shafts of the two second servo motors (23) are respectively connected to the two rotating swing frames (21), and the two rotating swing frames (21) are each installed with an electric rotary wing; The release process of the sub-drone (2) relative to the platform frame (1) is as follows: the corresponding electromagnet (11) is energized to generate a magnetic field, and the electromagnetic field and the corresponding permanent magnet block (10) generate a mutual magnetic attraction so that the elastic spring (9) between the two is compressed. The elastic spring (9) is compressed, causing the limit frame (8) connected to the elastic spring (9) to move in position within the mounting tube (4). After the limit frame (8) that has moved in position exits the limit slot (12) into which it is inserted, the sub-drone (2) is separated from the platform frame (1). After the separation of the sub-drone (2) from the platform frame (1) is achieved, the electromagnet (11) is powered off, and the separated sub-drone (2) runs along a U-shaped trajectory. The platform frame (1) continues to move forward and releases the sub-drones (2) again after flying an equal distance, until all the sub-drones (2) are released, and the platform frame (1) forms a return flight path. With the release of the sub-drones (2), the load of the platform frame (1) will gradually decrease. In order to maintain the same height of the sub-drones (2) released one after another, the height adjustment wing works to maintain the height of the platform frame (1). After the sub-drones (2) are completely released, the speed of the flying wing (26) in the height adjustment wing is reduced or stopped, so that the height of the platform frame (1) is increased and the return flight of the platform frame (1) is achieved under the action of the auxiliary adjustment wing. After the platform body (1) returns to the position near the initial release of the sub-unmanned aerial vehicle (2), the height adjustment wing works to achieve downward pressure on the flight height of the platform body (1), thereby achieving a height match with the released sub-unmanned aerial vehicle (2) to welcome the sub-unmanned aerial vehicle (2) after it has completed its operation in a U-shaped trajectory. The electromagnet (11) is energized again to form a magnetic attraction with the permanent magnet block (10) to facilitate the mounting rod (5) on the sub-unmanned aerial vehicle (2) to be inserted into the mounting tube (4) again. After the sub-unmanned aerial vehicle (2) forms a position match with the platform body (1), the mounting rod (5) is inserted into the mounting tube (4). When the pressure sensor (13) contacts the push rod (14) and forms a certain pressure value, the electromagnet (11) power is turned off, and under the action of the elastic spring (9), the limit frame (8) and the limit groove (12) interact with each other to realize the connection and positioning of the mounting rod (5) relative to the mounting tube (4) into which it is inserted, so as to achieve the re-mounting of the sub-unmanned aerial vehicle (2) relative to the platform frame (1). After all the sub-unmanned aerial vehicles (2) are recovered relative to the platform frame (1), a single working cycle of the ultra-long-distance flight surveying and mapping platform for geographic surveying and mapping is realized, and then the platform frame (1) continues to fly forward until it passes through the area surveyed and mapped by the previous working cycle, and then the sub-unmanned aerial vehicle (2) is released again to start the next working cycle, and the ultra-long-distance flight surveying and mapping is realized through the sequential work of multiple working cycles.
