It also includes: a quick-release component 5 arranged at the bottom of the first support plate 4 for quickly positioning and installing the control compartment 7 as a whole. By setting the quick-release component 5, the control compartment 7 and the first support plate 4 are quickly disassembled and assembled, which simplifies the disassembly and assembly process, reduces the difficulty of disassembly and assembly, and is conducive to the maintenance and repair of the electronic components inside the control compartment 7 in the later stage; the control compartment A controller 9 is fixedly installed on one side of the inner wall of 7. The controller 9 is a PLC controller or an integrated mainboard. By setting up the controller 9, other electronic devices can be centrally controlled, thereby improving the degree of automation and intelligence; a shooting component 8 is set on the outside of the control compartment 7 for collecting topographic map data during the flight of the drone body 1. By setting up the shooting component 8, topographic map data can be collected from a high altitude, and then the collected topographic map image data can be wirelessly transmitted to the ground server for secondary processing; the shooting component 8 is connected to the connection terminal of the controller 9 through a data cable, and a support component 2 is provided at the bottom of the drone body 1 to prevent the shooting component 8 from directly contacting the ground. By setting up the support component 2, on the one hand, the vibration force generated by the drone body 1 during takeoff and landing is reduced, and on the other hand, the shooting component 8 is prevented from directly contacting the ground when the drone body 1 lands, thereby protecting the shooting component 8.

[0024] The quick-install assembly 5 includes a U-shaped frame 51 fixed to the bottom of the first support plate 4. There are multiple U-shaped frames 51, which are symmetrically distributed on both sides of the first support plate 4. The U-shaped frame 51 is fixedly installed on the first support plate 4. A threaded column 52 is rotatably connected inside the U-shaped frame 51. A limiting groove 56 corresponding to the threaded column 52 is opened on the outside of the second support plate 6. The bottom end of the threaded column 52 passes through the outside of the limiting groove 56 and is spirally connected to a locking nut 53. A docking block 58 is fixedly connected to the top of the second support plate 6. A docking frame 57 is provided on the outside of the docking block 58. The top of the docking frame 57 is connected to the first support plate 4. Figure 3 、 Figure 4As shown, when positioning and installing the control compartment 7, the threaded column 52 in each U-shaped frame 51 can be passed through the corresponding limit groove 56 below it, and then the locking nut 53 is tightened so that the locking nut 53 is tightly fitted with the second support plate 6. Under the action of multiple threaded columns 52 and locking nuts 53, the second support plate 6 as a whole cannot be displaced, thereby simplifying the disassembly and assembly process, reducing the difficulty of disassembly and assembly, and realizing the rapid positioning and installation of the control compartment 7.

[0025] A friction washer 54 is provided between the locking nut 53 and the second support plate 6, and an anti-slip block 55 is fixedly connected to the bottom end of the threaded column 52.

An inspection port 86 is provided on the side of the control cabin 7 away from the front camera 81, and an inspection panel 83 is provided on one side of the inspection port 86. The wireless signal transceiver 84 on the ground sends a data collection instruction to the airborne wireless signal transceiver 84, and the wireless signal transceiver 84 transmits the instruction to the controller 9. After receiving the instruction, the controller 9 starts the front camera 81 and the overhead camera 82 to collect topographic map data. The collected topographic map image data will be converted into a wireless signal by the airborne wireless signal transceiver 84 and transmitted back to the wireless signal transceiver 84 on the ground. Finally, the ground server will parse, model and perform other operations on the received topographic map image data, so as to obtain topographic map measurement data quickly and conveniently.

[0027] A charging socket 12 is provided on one side of the control compartment 7, and the charging socket 12 is connected to the input end of the battery 85 through a wire.

The detection end of the infrared distance sensor 10 extends to the outside of the control chamber 7. The infrared distance sensor 10 is connected to the connection terminal of the controller 9 through a data line. Figure 5 As shown, by setting up an infrared distance sensor 10, obstacles on the flight path of the drone body 1 can be monitored in real time, and ground server staff can adjust the flight path of the drone body 1 in advance according to the location and distance of the obstacle, avoiding direct collision between the drone body 1 and the obstacle, thereby improving the flight safety of the drone body 1.

[0029] The support assembly 2 includes a tripod 24 provided at the bottom of both sides of the drone body 1. The top of each end of the tripod 24 is fixedly connected to a support rod 22. A guide cylinder 21 is provided above the support rod 22. The guide cylinder 21 is fixedly installed at the bottom of the drone body 1. The top of the support rod 22 passes through the inside of the guide cylinder 21 and is fixedly connected to a spring 23. The top of the spring 23 is connected to the guide cylinder 21. Figure 2 As shown, by providing the spring 23, the vibration force generated by the drone body 1 during take-off and landing is reduced, and the shooting component 8 is prevented from directly contacting the ground when the drone body 1 lands, thereby protecting the lens of the shooting component 8.

[0030] Working principle: First, the staff uses the ground server console to control the rise of the drone body 1. When the drone body 1 rises to a suitable height, it can receive instructions from the ground server in real time through the shooting component 8. It can also collect topographic map data and transmit the collected topographic map image data back to the ground server in the form of wireless signals. In this way, topographic map measurement data can be obtained quickly and conveniently. After the data collection work of the shooting component 8 is completed, the support component 2 can be used to reduce the vibration force generated when the drone body 1 lands, avoiding direct contact between the shooting component 8 and the ground. When the control cabin 7 needs to be maintained and repaired, the threaded column 52 and the locking nut 53 on each quick-release component 5 can be used to limit the displacement of the second support plate 6, thereby simplifying the disassembly and assembly process, reducing the difficulty of disassembly and assembly, and realizing the rapid positioning and installation of the control cabin 7.
