Description

Technical Field

[0001] The present invention relates to the technical field of remote sensing data acquisition, and particularly to a remote sensing mapping geographic information data acquisition platform. Background Art

[0002] Remote sensing mapping is a technology that uses various sensors on ground, aerial, and aerospace platforms to draw topographic maps or other thematic maps of the Earth or other celestial bodies. The images obtained by remote sensing mapping mainly rely on frame cameras and CCD cameras. By obtaining forward or side-looking overlapping stereo image pairs along the flight direction or different orbits, the elevation of ground points can be measured and the terrain can be mapped. The working wavelength of infrared remote sensing is mainly in the range of 0.76 - 15.0 micrometers. By using infrared sensitive elements, the infrared radiation energy of ground objects can be measured to obtain infrared image remote sensing data acquisition, which is a technology for collecting and monitoring surface information based on remote sensing platforms and sensors.

[0003] Currently, conventional remote sensing platforms include aerospace platforms (satellites), near-ground platforms (unmanned aerial vehicles, ground-mounted suspended platforms), and fixed platforms. Among them, near-ground platforms can achieve more refined data acquisition. In near-ground mapping, unmanned aerial vehicles and remote sensing mapping instruments installed under the unmanned aerial vehicles are used. Although they can adapt to the use of remote sensing mapping instruments of different heights and sizes, improving the applicable range of remote sensing mapping instruments. However, when using an unmanned aerial vehicle to carry a mapping device for mapping, there will be wind outdoors, especially on mountains. When the unmanned aerial vehicle carries a mapping device for operation, the size of the wind needs to be considered additionally. If the wind is too strong, mapping operations cannot be carried out. During the operation, the unmanned aerial vehicle is also easily blown away and gets out of manual control, or drops, causing great economic losses. In addition, in some key areas, the acquisition device needs to stay in a certain fixed area for a long time to obtain remote sensing data, and the unmanned aerial vehicle cannot hover in a certain fixed area for a long time for monitoring. And setting up a high platform on the ground has problems such as high cost and long construction period. Therefore, there is a need to provide a remote sensing mapping geographic information data acquisition platform that can suspend in the air for a long time and is easy to set up. Summary of the Invention

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] The embodiment provides a remote sensing mapping geographic information data acquisition platform, as Figure 1 - Figure 10 shown, for long-term remote sensing monitoring of a local area, which specifically includes a gas floating platform 1, a remote sensing sensor 8, a base plate 2, a first steel cable 4, a second steel cable 5, a triangular structure stabilizer 6, and a rod-type damper 7.

[0034] The gas floating platform 1 selects an airbag structure filled with hydrogen / helium inside, which can generate lift and rise upward, and relies on the first steel cable 4 and the second steel cable 5 to stabilize the gas floating platform 1. The remote sensing sensor 8 is fixedly installed on the outer surface of the gas floating platform 1, generally at the bottom of the gas floating platform 1. The remote sensing sensor 8 can be an optical sensor, a microwave sensor (active radar (SAR), passive microwave radiometer), a frame camera, etc., selected according to the monitored target.

[0035] Specifically, the base plate 2 is installed on the ground. A first steel cable 4 is arranged between the gas floating platform 1 and the base plate 2, and there are three groups of the first steel cables 4, which are distributed in a circular array (in an equilateral triangle distribution). The first steel cables 4 are in a vertical state. A second steel cable 5 is also arranged between the gas floating platform 1 and the base plate 2. There are three groups of the second steel cables 5, and the three groups of the second steel cables 5 are distributed in a circular array (in an equilateral triangle distribution). As Figure 1 、 Figure 2 shown in, the first steel cable 4 and the second steel cable 5 cross obliquely one by one, that is, one first steel cable 4 and one second steel cable 5 form a unit. In this unit, a triangular structure stabilizer 6 is fixedly installed on the second steel cable 5. The triangular structure stabilizer 6 is slidably matched with the first steel cable 4. A rod-type damper 7 is fixedly installed on the first steel cable 4. The top end of the rod-type damper 7 is fixedly connected to the triangular structure stabilizer 6. The rod-type damper 7 preferably uses a damper with gas as the medium, and its telescopic formation is more suitable for tensioning the second steel cable 5.

[0036] The remote sensing mapping geographic information data acquisition platform mainly relies on the remote sensing sensor 8 to obtain data and then transmits the data through wireless / wired networks; in this solution, the first steel cable 4 and the second steel cable 5 form two triangular cable structures in a cross form. The tension provided by the first steel cable 4 corresponds to the lift of the gas floating platform 1, and the tension provided by the second steel cable 5 is used to stabilize the position of the gas floating platform 1. And during the process of the gas floating platform 1 shifting in position, the second steel cable 5 close to the shifted side becomes slack. Relying on the elastic force of the rod-type damper 7 to drive the triangular structure stabilizer 6 to slide on the first steel cable 4, the second steel cable 5 is bent, so that the second steel cable 5 is in a tensioned state, preventing the gas floating platform 1 from tipping over. And the second steel cable 5 on the side far from the shifted side is tensioned at this time, hindering the gas floating platform 1 from continuing to shift, and the rod-type damper 7 and the triangular structure stabilizer 6 on this side can allow the second steel cable 5 to elastically slide relative to the first steel cable 4, so as to play a stabilizing role on the gas floating platform 1. In the entire system composed of the first steel cable 4, the second steel cable 5, the triangular structure stabilizer 6, and the rod-type damper 7, the gas floating platform 1 can be kept directly above the base plate 2 and the shift of the gas floating platform 1 can be continuously corrected.

[0037] In this embodiment, the remote sensing platform composed of the gas floating platform 1, the base plate 2, the first steel cable 4, the second steel cable 5, the triangular structure stabilizer 6 and the rod damper 7 can be used for a long time. Moreover, compared with building a high platform support, its construction period is short, the cost is low, and it can be reused after being disassembled.

[0038] In another embodiment, in order to further reduce the influence of the lateral air flow on the gas floating platform 1, the gas floating platform 1 is designed as follows: As Figure 4 shown, the gas floating platform 1 includes an inverted conical airbag 101. The structure of the inverted conical airbag 101 makes its rising process more stable. Two parallel distributed air holes 109 are arranged on the side of the inverted conical airbag 101. The cross-sectional shape of the air holes 109 is a waist-shaped hole, which is convenient for the lateral air flow to pass through the air holes 109, reducing the influence of the lateral air flow on the gas floating platform 1. The base plate 2 is a rotatable base, which can adjust the positions of the bottoms of the first steel cable 4 and the second steel cable 5, and then adjust the length direction of the air holes 109 of the gas floating platform 1 along the direction of the air flow.

[0039] In another embodiment, as Figure 10 shown, the base plate 2 includes a disk base 201, a first gear 203, a base platform 205, a control motor 206 and side arms 208. The disk base 201 is a hollow structure and is fixed on the ground. There is a shaft hole at the top of the disk base 201. The first gear 203 is rotatably installed inside the disk base 201. For example, a graphite protrusion 202 is fixedly arranged at the center position inside the disk base 201. The bottom of the first gear 203 corresponds to the graphite protrusion 202. The friction supported by the graphite protrusion 202 is smaller. The top of the first gear 203 is fixedly connected with a rotating shaft 204. The rotating shaft 204 is located inside the shaft hole. The base platform 205 is fixedly installed at the top of the rotating shaft 204. The bottom end of the first steel cable 4 is fixedly connected with the base platform 205. The control motor 206 is fixedly installed on the top of the disk base 201. The output end of the control motor 206 penetrates the disk base 201. A second gear 207 is fixedly installed at the output end of the control motor 206 and inside the disk base 201. The second gear 207 is meshed with the first gear 203 for transmission. The number of side arms is the same as the number of the second steel cables 5. One end of each side arm 208 is fixedly connected with the base platform 205, and the other end extends outside the base plate 2. The bottom end of the second steel cable 5 is fixedly connected with the end of the side arm far from the base platform 205.

[0040] When in use, the control motor 206 drives the second gear 207 to rotate, and then drives the first gear 203 to rotate. The first gear 203 drives the rotating shaft 204 to rotate, so as to drive the base platform 205 and the side arms to rotate. The design of the side arms can meet the installation requirements of the second steel cable 5 and reduce the overall material consumption of the base plate 2.

[0041] In order to stabilize the side arm, in the embodiment, an annular auxiliary member 3 is also designed, and the annular auxiliary member 3 is fixedly installed on the outer side of the disc base 201. As Figure 1 shown, the annular auxiliary member 3 specifically includes an annular seat and a rotating ring member 303. The annular seat is composed of a plurality of arc-shaped members 301, and a set of connecting bars 302 are fixedly connected between adjacent two arc-shaped members 301. When in actual use, they are assembled together to form an annular seat. The rotating ring member 303 is rotationally matched with the annular seat, and the bottom of the side arm is fixedly connected to the rotating ring member 303, and the rotating ring member 303 can rotate following the side arm.

[0042] In one embodiment, the top of the inverted conical airbag 101 is a top spherical surface 102, and the horizontal air flow acting on the top spherical surface 102 can provide additional lift. As Figure 4 and Figure 7 shown, inside the inverted conical airbag 101 and fixed between two parallel distributed air holes 109 are a cylindrical airbag 103 and a special-shaped airbag 105. There are two sets of special-shaped airbags 105, and the two sets of special-shaped airbags 105 are distributed on both sides of the cylindrical airbag 103. A communication air passage 106 is provided between the cylindrical airbag 103 and the special-shaped airbag 105, and a one-way air flow control component 107 is fixedly arranged inside the communication air passage 106. The inside of the inverted conical airbag 101 is filled with air, and the inside of the cylindrical airbag 103 and the special-shaped airbag 105 is filled with hydrogen / helium.

[0043] In this design scheme, a double-layer structure of the outside of the inverted conical airbag 101, the inside of the cylindrical airbag 103 and the special-shaped airbag 105 is adopted, which can well protect the cylindrical airbag 103 and the special-shaped airbag 105, and rely on the air to fill the inverted conical airbag 101, and its overall shape can be fixed. When the inverted conical airbag 101 leaks, the lift generated by the whole will not be small, and normal use can still be guaranteed, which is convenient for people to timely discover and repair the inverted conical airbag 101.

[0044] In one embodiment, the special-shaped airbag 105 is overall cylindrical, and the part of the special-shaped airbag 105 close to the side surface of the inverted conical airbag 101 is matched with the side surface of the inverted conical airbag 101, and the part of the special-shaped airbag 105 close to the side surface of the air hole 109 is matched with the side surface of the air hole 109, so that the shape of the special-shaped airbag 105 maximally fills the inner area of the inverted conical airbag 101.

[0045] In one embodiment, as Figure 4 and Figure 5As shown in the figure, an air inlet is provided at the bottom of the inverted conical airbag 101. A quick-connect charging pipe 104 is fixedly connected to the bottom of the cylindrical airbag 103 and inside the air inlet. A sealing cover 108 is fixedly connected to the bottom of the air inlet. When the cylindrical airbag 103 is inflated from the quick-connect charging pipe 104 of the cylindrical airbag 103, the gas can enter the special-shaped airbag 105 through the one-way air flow control component 107, realizing the rapid inflation of the cylindrical airbag 103 and the special-shaped airbag 105. And the one-way air flow control component 107 is designed to prevent the gas inside the special-shaped airbag 105 from flowing back into the cylindrical airbag 103. In this way, when the cylindrical airbag 103 is damaged, the two special-shaped airbags 105 can still be used.

[0046] In the embodiment, as Figure 5 shown, the one-way air flow control component 107 includes a lining member 107a, a first conical member 107c, and a second conical member 107d. The lining member 107a is fixedly installed inside the communication air passage 106. A double-cone channel hole 107b is provided inside the lining member 107a. A side port 107e is provided on the side surface of the first conical member 107c. The first conical member 107c is located on the side where the cylindrical airbag 103 is located, and the second conical member 107d is located on the side where the special-shaped airbag 105 is located. And the first conical member 107c and the second conical member 107d are fixedly connected together in a head-to-head form.

[0047] When the air pressure inside the cylindrical airbag 103 is high, the first conical member 107c closely fits the double-cone channel hole 107b. Since a side port is provided on the side surface of the first conical member 107c, the air flow can pass through and then pass through the gap between the second conical member 107d and the double-cone channel hole 107b. In the reverse direction, when the air pressure inside the special-shaped airbag 105 is high, the second conical member 107d closely fits the double-cone channel hole 107b to form a seal.

[0048] In the above embodiment, the connection points of the three groups of first steel guy ropes 4 and the gas floating platform 1 form an equilateral triangle A, and the connection points of the three groups of second steel guy ropes 5 and the gas floating platform 1 form an equilateral triangle B. The apex directions of the equilateral triangle A and the equilateral triangle B are opposite. As Figure 6 shown, the stagger angle θ between the two triangles belongs to (3°, 8°), so as to reduce the intersection between the three groups of second steel guy ropes 5 and reduce the friction between the three groups of second steel guy ropes 5. The connection points of the three groups of first steel guy ropes 4 and the base plate 2 form an equilateral triangle C, and the connection points of the three groups of second steel guy ropes 5 and the base plate 2 form an equilateral triangle D. The apex directions of the equilateral triangle C and the equilateral triangle D are the same, forming a structure in which the first steel guy ropes 4 and the second steel guy ropes 5 cross obliquely.

[0049] Working process of the present invention: First, fix the base plate 2 and the annular auxiliary member 3 on the ground. Connect the gas floating platform 1 and the base plate 2 through three groups of first steel cables 4 and three groups of second steel cables 5. The first steel cables 4 are in a vertical state and play a main fixing role. The first steel cables 4 and the second steel cables 5 are obliquely crossed one by one, that is, one first steel cable 4 and one second steel cable 5 form a unit. In this unit, a triangular structure stabilizer 6 is fixedly installed on the second steel cable 5. The triangular structure stabilizer 6 is slidably matched with the first steel cable 4. A rod damper 7 is fixedly installed on the first steel cable 4. The top end of the rod damper 7 is fixedly connected to the triangular structure stabilizer 6. Then, obtain data through the remote sensing sensor 8 installed on the outer surface of the gas floating platform 1 and transmit the data through a wireless / wired network. During the monitoring process, the first steel cables 4 and the second steel cables 5 form two triangular cable structures in a crossed form. The tension provided by the first steel cables 4 corresponds to the lifting force of the gas floating platform 1. The tension provided by the second steel cables 5 is used to stabilize the position of the gas floating platform 1. And during the process of the gas floating platform 1 shifting in position, the second steel cable 5 close to the shifted side becomes slack. Relying on the elastic force of the rod damper 7, drive the triangular structure stabilizer 6 to slide on the first steel cable 4, bend the second steel cable 5, and make the second steel cable 5 in a tensioned state to prevent the gas floating platform 1 from tipping over. And the second steel cable 5 on the side far from the shifted side is tensioned at this time, hindering the gas floating platform 1 from continuing to shift. And the rod damper 7 and the triangular structure stabilizer 6 on this side can allow the second steel cable 5 to elastically slide relative to the first steel cable 4, thereby playing a stabilizing role on the gas floating platform 1.

[0050] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
