Description

Technical Field

[0001] The present invention relates to the field of surveying and mapping technology, and specifically to a surveying and mapping device for forest land topographic maps. Background Art

[0002] Surveying and mapping means measuring and mapping. Based on computer technology, optoelectronic technology, network communication technology, space science, and information science, with the global navigation satellite positioning system, remote sensing, and geographic information system as the technical core, the existing feature points and boundaries on the ground are obtained through measurement means to obtain graphics and position information reflecting the current situation of the ground for the planning and design of engineering construction and administrative management. Surveying and mapping methods include ordinary surveying and photogrammetry, etc.

[0003] During the process of surveying and mapping in a lush forest area, the ground is mostly soil and the slope is inclined, which is not conducive to the stable placement of ground equipment. Therefore, aerial drones are usually used for the surveying and mapping operation of topographic maps to improve the efficiency and convenience of surveying and mapping. However, this type of drone has the following problems. Since data transmission depends on the communication module of the drone for transmission, as the distance increases, the signal strength of the drone decreases, making it impossible for personnel to receive data stably and also impossible to control the drone stably. At the same time, since the drone needs to carry additional surveying and mapping equipment, this will increase the load of the drone, reducing the endurance of the drone under limited power and shortening the surveying and mapping time, which is not conducive to long-term aerial surveying and mapping operations.

Detailed implementation manners

[0031] The technical solutions of the present invention will be further described in detail below in conjunction with the specific implementation manners.

[0032] Example 1, refer to Figures 1 to 10 As shown, a topographic map surveying and mapping device for forest land includes a frame 1, and the frame 1 is fixedly connected with a wireless control module, and further includes:

[0033] A mobile carrying structure 2 connected to the frame 1;

[0034] Two sets of flight lifting structures 3 connected to the mobile carrier structure 2. The flight lifting structure 3 includes a drone body 4 movably connected to the mobile carrier structure 2. An auxiliary power supply 5 is fixedly installed inside the drone body 4. The drone body 4 is connected to two sets of wire suspension mechanisms 6. One set of wire suspension mechanisms 6 is connected to two communication plugs 7, and the other set of wire suspension mechanisms 6 is connected to two power supply plugs 8;

[0035] Three sets of docking surveying and mapping structures 9 connected to the frame 1. The docking surveying and mapping structure 9 includes a first protective frame 10 movably connected to the frame 1. The first protective frame 10 is fixedly connected with a camera surveying and mapping module 11. The first protective frame 10 is fixedly connected with two sets of first docking parts 12. One set of first docking parts 12 is used for docking with two communication plugs 7, and the other set of first docking parts 12 is used for docking with two power supply plugs 8;

[0036] Two sets of auxiliary plugging structures 13 connected to the mobile carrier structure 2. The auxiliary plugging structure 13 enables the wire suspension mechanism 6 to perform docking operations with the first docking part 12 by driving the movement of the wire suspension mechanism 6;

[0037] Two sets of relay signal transmission structures 14 connected to the frame 1. The relay signal transmission structure 14 includes a second protective frame 15 movably connected to the frame 1. The second protective frame 15 is fixedly connected with a wireless signal relay transmitter 16. Two sets of second docking parts 17 are fixedly installed on the top of the second protective frame 15. The second docking part 17 has the same structure as the first docking part 12.

[0038] In use, the auxiliary plugging structure 13 docks the two wire suspension mechanisms 6 under the UAV body 4 with the two first docking parts 12 on the same first protective frame 10. Then, both the communication plug 7 and the power supply plug 8 are docked with the first docking part 12. At this time, as the UAV body 4 takes off, the wire suspension mechanism 6 lifts the first docking part 12 to lift the first protective frame 10. The first protective frame 10 drives the camera mapping module 11 to move, so that the camera mapping module 11 moves in the air and performs shooting operations for map drawing operations. When it is necessary to enhance the endurance of the present invention, the auxiliary plugging structure 13 respectively docks the two first docking parts 12 on the same first protective frame 10 with one wire suspension mechanism 6 of the two UAV bodies 4. During this period, the two communication plugs 7 are docked with one first docking part 12, and the two power supply plugs 8 are docked with the first docking part 12 under the other UAV body 4. Driven by the two UAV bodies 4, the two wire suspension mechanisms 6 jointly lift a set of docking and mapping structure 9.

The auxiliary plugging structure 13 docks the two wire suspension mechanisms 6 under one of the UAV bodies 4 with the two second docking parts 17 on the same second protective frame 15. Then, both the communication plug 7 and the power supply plug 8 are docked with the second docking part 17. The wireless signal relay transmitter 16 moves between the wireless control module and the camera mapping module 11 performing mapping operations, so that the wireless signal relay transmitter 16 performs signal relay transmission operations to ensure the strength and stability of the signal transmission of the other UAV body 4. Through the mutual cooperation of the mobile carrier structure 2, the flight lifting structure 3, the docking and mapping structure 9, the auxiliary plugging structure 13, and the relay signal transmission structure 14, the present invention realizes mapping operations on the terrain from the air, and by changing the structure suspended under the flight lifting structure 3, the stability of the signal transmission of the present invention and the maximum endurance of the mapping of the present invention are enhanced.

[0039] In a case of this embodiment, the mobile carrier structure 2 includes a slide rod 18 fixedly connected to the frame 1. The frame 1 is rotatably connected to a screw rod 19.

The screw rod 19 is threadedly connected with a linkage frame 21. The linkage frame 21 is slidably connected to the slide rod 18. The linkage frame 21 is connected to the auxiliary plugging structure 13. The linkage frame 21 is fixedly connected with two stop brackets 22. The stop brackets 22 are movably connected to the UAV body 4. The first motor 20 drives the screw rod 19 to rotate. The rotating screw rod 19 drives the linkage frame 21 to move along the slide rod 18. The moving linkage frame 21 drives the stop brackets 22 to move to adjust the position of the UAV body 4. At the same time, the linkage frame 21 drives the auxiliary plugging structure 13 to move.

[0040] In a case of this embodiment, the wire suspension mechanism 6 includes a hanging bracket 23 movably connected to the UAV body 4. A box body 24 is fixedly installed at the lower end of the hanging bracket 23. The box body 24 is fixedly connected to a double-output shaft motor 25. The output ends of the double-output shaft motor 25 are fixedly connected to wire wheels 26. The two sets of wire wheels 26 connected to the same double-output shaft motor 25 are arranged in the same set of box bodies 24. The wire wheels 26 in a set of box bodies 24 arranged below the UAV body 4 are wound with a power supply cable 27. The power supply cable 27 is electrically connected to the power supply plug 8. The wire wheels 26 in another set of box bodies 24 arranged below the same UAV body 4 are wound with a communication cable 28. The communication cable 28 is communicatively connected to the communication plug 7. Both the power supply cable 27 and the communication cable 28 are fixedly connected to a docking head 29. An annular card slot 42 is formed in the docking head 29. An annular ball groove 30 adapted to the first docking portion 12 is formed on the surface of the docking head 29. The double-output shaft motor 25 drives the wire wheels 26 to rotate. The rotating wire wheels 26 are used to wind the power supply cable 27 or the communication cable 28, so as to adjust the height of the docking head 29. The power supply plug 8 is electrically connected to the auxiliary power supply 5 of the UAV body 4 through the power supply cable 27. The communication plug 7 is communicatively connected to the wireless communication module inside the UAV body 4 through the communication cable 28. Under normal circumstances, the annular ball groove 30 is connected to the first docking portion 12, so that the wire suspension mechanism 6 is docked with the first docking portion 12.

[0041] In a case of this embodiment, both the first docking portion 12 and the second docking portion 17 include a chassis 31. The chassis 31 of the first docking portion 12 is fixedly connected to the first protection frame 10, and the chassis 31 of the second docking portion 17 is fixedly connected to the second protection frame 15. The chassis 31 is fixedly connected with multiple groups of pipe bodies 32. The pipe bodies 32 are fixedly connected with springs, and the springs are fixedly connected with hemispherical plugs 34. The hemispherical plugs 34 are fixedly connected with extrusion heads 36 through connecting rods 35. The extrusion heads 36 are slidably installed in the pipe bodies 32. The chassis 31 is slidably connected with a plugging frame 37, and the pipe bodies 32 are slidably connected with the plugging frame 37. The chassis 31 is fixedly connected with eight groups of second active telescopic rods 38. The moving ends of every four groups of the second active telescopic rods 38 are commonly fixedly connected with a plugging frame 37. The plugging frame 37 is slidably connected with the chassis 31. One group of chassis 31 on the first protection frame 10 is fixedly connected with two power supply sockets 40, and the other group of chassis 31 on the same first protection frame 10 is fixedly connected with two communication sockets 41. One group of chassis 31 on the second protection frame 15 is fixedly connected with the two power supply sockets 40, and the other group of chassis 31 on the same second protection frame 15 is fixedly connected with the two communication sockets 41. The second active telescopic rods 38 drive the plugging frame 37 to move, so that the plugging frame 37 disengages from the pipe body 32. Then, the docking head 29 is inserted into the chassis 31. The docking head 29 presses the hemispherical plug 34. Then, under the push of the spring on the hemispherical plug 34, the hemispherical plug 34 is snapped into the annular ball groove 30. During this period, the power supply socket 40 is docked with the power supply plug 8, and the communication socket 41 is docked with the communication plug 7. The second active telescopic rods 38 drive the plugging frame 37 to plug the pipe body 32, thereby hindering the movement of the extrusion head 36. Since the extrusion head 36 is fixedly connected with the hemispherical plug 34 through the connecting rod 35, at this time, the end of the hemispherical plug 34 continuously embeds into the annular ball groove 30, thereby preventing the hemispherical plug 34 from accidentally disengaging from the annular ball groove 30.

[0042] In a case of this embodiment, the auxiliary plugging structure 13 includes a track frame 43 fixedly connected to the linkage frame 21. The track frame 43 is fixedly connected with two groups of third active telescopic rods 44. The moving end of the third active telescopic rod 44 is fixedly connected with a longitudinal frame 45 slidably connected to the track frame 43. The longitudinal frame 45 is fixedly connected with a second motor 46. The output end of the second motor 46 is fixedly connected with a lead screw 47. The lead screw 47 is threadedly connected with a motor base 48 slidably connected to the longitudinal frame 45. The motor base 48 is fixedly connected with a third motor 49. The output shaft of the third motor 49 is fixedly connected with a double-headed clamping frame 50. The double-headed clamping frame 50 is matched with the annular card slot 42. The third active telescopic rod 44 drives the longitudinal frame 45 to slide along the track frame 43. The longitudinal frame 45 drives the second motor 46 to move. The second motor 46 drives the lead screw 47 to rotate. The rotating lead screw 47 drives the motor base 48 to slide along the longitudinal frame 45. The motor base 48 drives the third motor 49 to move. The third motor 49 drives the double-headed clamping frame 50 to move. The double-headed clamping frame 50 makes the docking head 29 move together with the moving double-headed clamping frame 50 by being inserted into the annular card slot 42. The third motor 49 drives the double-headed clamping frame 50 to rotate to adjust the orientation of the double-headed clamping frame 50.
