[0002] The data acquisition equipment used for UAV surveying and mapping mainly includes high-precision surveying and mapping sensors and related data processing systems. Surveying and mapping sensors are the core components of UAV surveying and mapping tasks, and they can obtain various information about ground targets. Common surveying and mapping sensors include laser rangefinders, global positioning system (GPS) receivers, inertial measurement units (IMUs), and high-resolution cameras. Laser rangefinders can accurately measure the distance from the UAV to the ground target; GPS receivers can determine the precise position of the UAV; IMUs can measure the attitude and acceleration of the UAV; high-resolution cameras can obtain high-resolution images of the ground, and the data processing system is responsible for receiving and processing the data obtained by these sensors. During the flight, the UAV will transmit this data in real time to the ground station or cloud server for processing. The processing process includes data solution, calibration, splicing and modeling, and finally generates high-precision topographic maps, three-dimensional models and other surveying and mapping results.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1: This embodiment is intended to promote the solution of the problem that in the prior art data acquisition equipment for drone surveying and mapping, most of the measuring devices 200 are connected to the drone by bolts or directly installed as a whole during installation. When the measuring device 200 is damaged and needs to be repaired or replaced, the drone needs to be disassembled on a large scale, which is time-consuming and laborious during the repair process. Please refer to Figure 1-Figure 6 A data acquisition device for unmanned aerial vehicle surveying and mapping includes a measuring device 200 and a top cover 110. The measuring device 200 is fixedly installed in the middle of a connection box 190. A fixing frame 180 is snap-connected to the side of the connection box 190. A fixing frame 170 is fixedly installed on the side of the fixing frame 180. The fixing frame 170 is installed on a bottom plate 230. The bottom plate 230 is fixedly installed under the top cover 110 by fixing bolts 240. A mounting groove 210 is provided in the middle of the top cover 110 and the bottom plate 230. A battery 220 is fixedly installed in the middle of the mounting groove 210.

[0025] A connecting rod 130 is inserted into the side of the mounting groove 210, a mounting frame 140 is fixedly installed at the end of the connecting rod 130, a wing 120 is installed above the mounting frame 140, a supporting column 150 is fixedly installed below the mounting frame 140, a blocking slide block 160 is fixedly installed at the bottom of the supporting column 150, the blocking slide block 160 is in contact with the ground, a limiting groove 250 is provided in the middle of the fixing frame 180, a connecting box 190 is snap-connected in the middle of the limiting groove 250, and a snap-in groove 260 is provided on the side of the connecting box 190.

[0026] When the measuring device 200 needs to be replaced, the staff will first remove the fixing frame 180 from the drone, and then pull the connecting box 190 out of the fixing frame 180. When the connecting box 190 is pulled out of the fixing frame 180, the block 270 will slide out of the slot 260 smoothly due to the pulling force and the rounded corners of the slot 260, so that the connecting box 190 can be removed and replaced.

[0027] In the present embodiment: through the snap-fit ​​setting of the fixing frame 180 and the connecting box 190, when the measuring device 200 is damaged and needs to be repaired or replaced, the measuring device 200 can be more convenient to disassemble through the snap-fit ​​connection, and there is no need to disassemble the drone on a large scale, which can greatly reduce the maintenance time and save time cost. It solves the problem of connecting with the drone by bolt fixing or directly installing the whole device with the drone mentioned in the above background technology. Then, when the measuring device 200 is damaged and needs to be repaired or replaced, the drone needs to be disassembled on a large scale, which makes the maintenance process more time-consuming and labor-intensive.

[0028] Embodiment 2: This embodiment is intended to promote the solution of the problem that in the prior art UAV surveying and mapping data acquisition equipment, if the UAV is installed in an integral installation manner, it is not convenient to disassemble when it needs to be repaired, and when it needs to be replaced, the economic cost will be greatly increased. This embodiment is an improvement made on the basis of Embodiment 1. For details, please refer to Figure 1-Figure 6 A stabilizing block 380 is fixedly installed above the limiting groove 250 and on the inner wall of the fixing frame 180 , a stabilizing sheet 390 is fixedly connected below the stabilizing block 380 , a reinforcing sheet 400 is fixedly installed below the stabilizing sheet 390 , and a limiting cylinder 340 is contacted and connected below the reinforcing sheet 400 .

[0029] A stabilizing groove 350 is provided in the middle of the limiting cylinder 340, a fixing block 370 is slidably connected to one side of the stabilizing groove 350, a fixing rod 360 is fixedly connected to the side of the fixing block 370, a connecting groove 290 is provided on the side of the fixing column, an extrusion spring 280 is connected to the middle of the connecting groove 290, a clamping block 270 is fixedly connected to the bottom of the extrusion spring 280, and the clamping block 270 is engaged with the clamping groove 260, a limiting spring 330 is arranged in the middle of the limiting cylinder 340, one end of the limiting spring 330 is fixedly connected to the fixing block 370, and the other end of the limiting spring 330 is fixedly connected to the pushing block 320.

[0030] The push block 320 is slidably connected in the stabilizing groove 350, and a connecting column 310 is fixedly connected to the side of the push block 320. A connecting tube 300 is inserted into the side of the connecting column 310. The connecting tube 300 is fixedly connected to the connecting groove 290. The connecting groove 290, the clamping block 270 and the extrusion spring 280 are all symmetrically arranged with the stabilizing block 380 as the center.

[0031] During installation, the connection box 190 is directly inserted into the limiting groove 250, and the extrusion spring 280 on the side of the slider will pass through the limitation of the side of the connection box 190 to squeeze the extrusion spring 280. When the block 270 encounters the slot 260, it will be released so that the block 270 and the slot 260 are engaged and connected. During the engagement process, when the connection box 190 is pushed, the connection box 190 will first push the connection tube 300, so that the connection tube 300 and the connection rod 130 are extended and retracted, and then the connection rod 130 will push the push block 320 to squeeze the limiting spring 330.

[0032] When the connecting box 190 does not move, the limit spring 330 will push the push block 320 and the connecting rod 130, and the connecting rod 130 will push the connecting tube 300. At this time, the block 270 on the side of the connecting tube 300 will be engaged with the block 270. At this time, both blocks 270 are engaged with the slots 260, which will improve the stability of the connection between the connecting box 190 and the fixed frame 180.

[0033] In this embodiment: through the installation of the stabilizing block 380 and the limiting cylinder 340, when the connecting box 190 is engaged and connected, the connecting box 190 is directly pushed into the limiting groove 250. Due to the setting of the block 270 and the extrusion spring 280, during the pushing process, the extrusion spring 280 will be compressed, so that the connecting box 190 slides faster. When the block 270 encounters the slot 260, the extrusion spring 280 will be released, and the extrusion spring 280 will push the block 270, so that the block 270 and the slot 260 are engaged and connected. Through the cooperation of a series of structures, the convenience of the measuring device 200 during installation and disassembly is further improved, thereby greatly improving the work efficiency.
