Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles, and in particular to a multi-spectral remote sensing data acquisition unmanned aerial vehicle carrying platform. Background Art

[0002] The multispectral remote sensing data acquisition UAV-mounted platform is a system combination that places multispectral remote sensing data acquisition equipment on a UAV. It is generally used in agriculture, environmental monitoring, water resources scheduling, flood warning, and natural resource surveys.

[0003] In actual use, the existing multispectral remote sensing data collection drone-mounted platform can facilitate collectors to collect hydrological data of inland river basins, but it does not have an anti-sinking function. When the propeller of the drone fails to rotate normally during the inland river data collection process, the drone will fall into the river. At this time, the drone without an anti-sinking function will not be able to prevent it from sinking into the water, which will result in the collectors being unable to find it later and taking back the data collected by the drone in advance. As a result, the collectors have to collect the data again, which not only increases the collectors' working time, but also reduces the data collection efficiency.

An antenna 115 is installed on the top of one of the connecting ends of each drone body 101. A protective shell 3 is arranged at the bottom of the rectangular plate 105. Three mounting blocks 109, a multispectral sensor 110, a laser radar 111 and a flow meter 112 are all located inside the protective shell 3. Single-hole blocks 4 are fixed on both sides of the protective shell 3 near the top. Two symmetrical perforated blocks 9 are fixed on the top of the porous plate 108. A clamping rod 5 is arranged between the inside of each single-hole block 4 and the inside of each perforated block 9. A clamping hole 6 is opened on the outer surface of the clamping end of each clamping rod 5. A hook 8 is arranged inside each clamping hole 6, and a spring 7 is installed between the connecting ends of the two hooks 8.

[0038] In this embodiment, when the worker needs to use the multispectral remote sensing data collection drone platform to collect inland river data, the drone body 101 is first turned on, and then the drone body 101 is wirelessly connected to the collector's remote control through the antenna 115. Then, the various usage parameters of the drone body 101 are set, and then the nuts on the bolts used to connect the U-shaped block 106 and the connecting block 107 are loosened first, and then the multispectral sensor 110, the laser radar 111 and the flow meter 112 are adjusted by using the cooperation of the porous plate 108, the connecting block 107 and the plurality of mounting blocks 109. 1 and the velocity meter 112 are adjusted, the nut can be directly tightened at this time. When everything is ready, the collector can directly use the remote control to start the drone body 101 to take off. When the collector uses the remote control to move the drone body 101 above the river, the collector can use the remote control and the drone body 101 to cooperate with each other to start the multispectral sensor 110 first, collect water surface area data of the river, until the water surface area data collection is completed, then turn off the multispectral sensor 110, and then start the laser radar 111 to collect water depth data of the river, until the water depth data collection is completed, then turn off the laser radar 111, and then start the velocity meter 112 to collect water depth data in the river. The water flow data is collected until the water flow velocity collection is completed, and then the velocity meter 112 is turned off, and then the remote control is used to return the drone body 101, and then the tool is used to read the data in the built-in storage chip of the drone body 101. If a storage card is used to store data, it can be directly removed from the drone body 101, and then it can be read out using a card reader and equipment. When the drone body 101 completes the data collection operation, the collector can use the remote control to return the drone body 101, and then turn it off, and then use the protective shell 3 to cover the multispectral sensor 110, the laser radar 111, the velocity meter 112 and the multiple mounting blocks 109. At this time, the moving protective shell 3 will also drive the two single-hole blocks 4 connected to it to move. When the surface of the opening of the protective shell 3 contacts the surface of the porous plate 108, the angle of the protective shell 3 is fine-tuned to make the interior of each single-hole block 4 communicate with the interior of each perforated block 9 respectively, and then the clamping end of each clamping rod 5 is passed through the interior of each single-hole block 4 and the interior of each perforated block 9 respectively, and then the two hooks 8 are pulled in opposite directions to stretch the spring 7, and then the two hooks 8 are passed through the interiors of the two clamping holes 6 respectively, and then the force applied to the two hooks 8 is released, that is, the contraction force of the spring 7 and the cooperation of the two hooks 8 and the two clamping holes 6 are used to prevent the clamping rod 5 from moving.

[0039] The effect and working principle of the entire mechanism are as follows: when workers need to use the multispectral remote sensing data collection drone platform to collect inland river data, first turn on the switch of the drone body 101, then wirelessly connect the drone body 101 to the collector's remote control through the antenna 115, then set the various usage parameters of the drone body 101, and then loosen the nuts on the bolts used to connect the U-shaped block 106 and the connecting block 107, and then use the cooperation of the porous plate 108, the connecting block 107 and the multiple mounting blocks 109 to adjust the working angles of the multispectral sensor 110, the laser radar 111 and the flow meter 112. When the angles of the multispectral sensor 110, the laser radar 111 and the flow meter 112 are When the degree is adjusted, just tighten the nut directly. When everything is ready, the collector can directly use the remote control to start the drone body 101 to take off. When the collector uses the remote control to move the drone body 101 above the river, the collector can use the remote control and the drone body 101 to cooperate with each other to start the multispectral sensor 110 first, collect water surface area data of the river, until the water surface area data collection is completed, then turn off the multispectral sensor 110, and then start the laser radar 111 to collect water depth data of the river until the water depth data collection is completed, then turn off the laser radar 111, and then start the current meter 112 to collect water flow data in the river until the water flow velocity collection is completed, and then turn off the current meter 112. , and then use the remote control to return the drone body 101, and then use the tool to read the data in the built-in storage chip of the drone body 101. If a storage card is used to store data, it can be directly removed from the drone body 101, and then it can be read out using a card reader and equipment. When the drone body 101 is collecting data on the river, if one or more propellers cannot rotate, the drone body 101 will lose balance and fall. At the same time, the propeller drive motor fault monitoring module inside the drone body 101 will also transmit a signal to the control board inside the drone body 101. After receiving the signal, the control board inside the drone body 101 will directly start the two motor bodies 205 at the same time. Each motor body 205 will drive the corresponding main shell 201 to rotate with the cooperation of a corresponding set of cylindrical holes 202, bearings, rotating rods 203 and collars 204. When the two main shells 201 cannot rotate, the control panel inside the drone body 101 will pause the two motor bodies 205 at the same time, then open the valves of the two electric valves 210 at the same time, and then start the two micro fans 209 at the same time. Then, each started micro fan 209 will inhale the air in the environment with the cooperation of the connected electric valve 210 with the valve opened, and then transport it to the inside of the connected hose 211, and then transport it to the inside of the corresponding air bag 208. When the inside of the two air bags 208 are continuously injected with gas,At this time, the two airbags 208 will continue to expand and detach from the corresponding auxiliary shell 207. When a proper amount of air is injected into the two airbags 208, the control panel inside the drone body 101 will directly close the two electric valves 210 and the two micro fans 209. At this time, the drone body 101 that has fallen into the water will also float in the water and will not sink. At this time, the collector can easily find the drone body 101 that has fallen into the water, and then take it out of the water to obtain various data collected in advance. When the drone body 101 completes the data collection operation, the collector can use the remote control to return the drone body 101, and then close it, and then use the protective shell 3 to place the multispectral sensor 110 and the laser radar 111 , the velocity meter 112 and the multiple mounting blocks 109 are covered. At this time, the moving protective shell 3 will also drive the two single-hole blocks 4 connected to it to move. When the surface of the opening of the protective shell 3 contacts the surface of the porous plate 108, the angle of the protective shell 3 is fine-tuned to make the interior of each single-hole block 4 communicate with the interior of each perforated block 9 respectively. Then, the clamping end of each clamping rod 5 is passed through the interior of each single-hole block 4 and the interior of each perforated block 9 respectively. Then, the two hooks 8 are pulled in opposite directions to stretch the spring 7. Then, the two hooks 8 are passed through the interiors of the two clamping holes 6 respectively. Then, the force applied to the two hooks 8 is released, that is, the contraction force of the spring 7, the cooperation of the two hooks 8 and the two clamping holes 6 are used to prevent the clamping rod 5 from moving. ,
