Abstract
Description
Technical Field
[0001] This invention relates to the field of mining area monitoring equipment technology, specifically a mining area monitoring device based on multispectral sensors and lidar. Background Technology
[0002] Mining areas are prone to surface subsidence and collapse due to underground mining. Slopes, such as tailings dams and open-pit mine slopes, are also at risk of landslides. However, the combination of multispectral sensors and lidar can achieve comprehensive and high-precision monitoring of mining areas from topography, resource extraction, ecological environment and production safety through dual monitoring dimensions of three-dimensional spatial morphology and material spectral properties. Therefore, we propose a mining area monitoring device based on multispectral sensors and lidar.
[0003] The existing technology still has the following drawbacks in its use: In existing mining area monitoring equipment, when using multispectral sensors and lidar for mining area environmental monitoring, the monitoring range and accuracy are easily affected by the lighting conditions and line of sight of the environment, since both multispectral sensors and lidar are based on optical principles. Furthermore, the mining and transportation operations in the mining area generate a large amount of dust that floats in the air, resulting in poor monitoring performance of traditional mining area monitoring equipment.
[0004] In view of this, we propose a mining area monitoring device based on multispectral sensors and lidar to solve the existing problems. Summary of the Invention
[0005] The purpose of this invention is to provide a mining area monitoring device based on multispectral sensors and lidar to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a mining area monitoring device based on multispectral sensors and lidar, comprising a flow guiding component, a mounting cylinder and a monitoring component, wherein a base is bolted to the bottom of the mounting cylinder, and several bolts are installed through the interior of the base, a main control box is fixedly installed on one side of the top of the base, and a storage battery is fixedly installed inside the mounting cylinder. Several cylinders are bolted to the top of the mounting cylinder; A flow guide assembly is bolted to the top of the cylinder; A monitoring component is bolted to the top of the flow guiding assembly.
[0007] Preferably, the flow guiding component includes a flow guiding cylinder, which is a hollow cylindrical structure, and has several air inlet holes on its side wall. A fan is fixedly installed inside the flow guiding cylinder near the top.
[0008] Preferably, an isolation net is fixedly installed on the side wall of the guide tube at the air inlet position, and a gap is provided between the isolation net and the side wall of the guide tube.
[0009] Preferably, the monitoring component includes a housing with a top diameter larger than a bottom diameter and is connected to a flow guiding component. A viewing window is fixedly installed inside the housing. Two sets of exhaust holes are provided on the side wall of the housing, and the two sets of exhaust holes are respectively located near the top and bottom of the side wall of the housing. The exhaust holes are both oriented diagonally downward. Two sets of multispectral sensors are installed inside the housing facing away from each other.
[0010] Preferably, a top cover is fixedly installed on the top of the housing, an electromagnetic slide rail is fixedly installed on the top of the top cover, a solid-state lidar is slidably installed inside the electromagnetic slide rail, a cover is fixedly installed above the electromagnetic slide rail, and a photovoltaic power generation panel is fixedly installed on the top of the cover.
[0011] Preferably, a plurality of drainage cones are fixedly installed at the bottom edge of the top cover and the cover, wherein the bottom diameter of the drainage cones is smaller than the top diameter.
[0012] Preferably, the photovoltaic power generation panel is electrically connected to the main control box and the storage battery via a cable.
[0013] Compared with the prior art, the beneficial effects of the present invention are: This invention, by providing two sets of exhaust holes inside the housing and combining them with the airflow generated by the air guiding component, can exhaust the air inside the device to form an air curtain based on the two sets of downward-facing exhaust holes. This disperses the air in the environment where the device is located, preventing the device from being affected by rain, fog and dust during the monitoring process, and ensuring that the device can have good monitoring effect when working in the mining environment.
[0014] This invention, by installing an isolation net on the outside of the guide tube, can prevent a large amount of impurities in the mining environment from entering the guide tube and causing dust accumulation inside the device. On the other hand, the isolation net can also guide rainwater on the outer wall of the device to the tube and discharge it to the ground, preventing the device from sucking rainwater into the device during operation. This can prevent water ingress and water vapor from damaging the multispectral sensor. Attached Figure Description

[0017] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0018] like Figure 1 - Figure 8 As shown, the present invention proposes a mining area monitoring device based on a multispectral sensor 406 and a lidar, comprising a flow guiding component 1, a mounting cylinder 3, and a monitoring component 4. A base 301 is bolted to the bottom of the mounting cylinder 3, and several bolts are installed through the interior of the base 301. A main control box 302 is fixedly mounted on one side of the top of the base 301. A storage battery 303 is fixedly installed inside the mounting cylinder 3. The mounting cylinder 3 cooperates with the base 301 to support the bottom of the device, ensuring stability during operation and preventing significant shaking that could affect the monitoring performance of the multispectral sensor 406 and the solid-state lidar 401. The main control box 302 can be electrically connected to other electronic components via cables to control the internal electronic components, enabling multiple electronic components to work collaboratively. The storage battery 303 stores the electrical energy generated by the photovoltaic panel 409 to power the internal electronic components. The top of the mounting cylinder 3 is bolted with several cylinders 2. The cylinders 2 can be stacked as needed, so that the monitoring components 4 of the device can be installed at the designated monitoring position, ensuring that the device can have a relatively good field of view for monitoring the mining environment. The top of the cylinder 2 is bolted with a flow guide assembly 1. The flow guide assembly 1 enables the air inside the device to flow into the housing 403. On the one hand, it can use the high-speed airflow to spray out from the exhaust port 405 to form an air curtain, which protects the area around the device, prevents dust accumulation, and provides a better monitoring field of view for the multispectral sensor 406. On the other hand, the airflow can be used to achieve wind cooling of the components inside the device, ensuring that the device has good working stability in the outdoor environment of the mining area. The top of the flow guiding component 1 is bolted with a monitoring component 4. The monitoring component 4 can perform three-dimensional terrain scanning of the mining area environment and monitor environmental elements such as vegetation, soil and water in the mining area based on the multispectral sensor 406 and solid-state lidar 401.
[0019] Furthermore, the flow guiding component 1 includes a flow guiding cylinder 101, which is a hollow cylindrical structure, and several air inlets 103 are provided on the side wall of the flow guiding cylinder 101. A fan 104 is fixedly installed inside the flow guiding cylinder 101 near the top. The flow guiding cylinder 101 can provide a mounting position for the surrounding components and guide the airflow vertically upward into the housing 403. The air inlets 103 enable the fan 104 to draw air from the external environment into the flow guiding cylinder 101, so that an air curtain is formed at the exhaust port 405 for protection, and air cooling is achieved for the components inside the housing 403. The fan 104 is of type FDL-4C, and the fan 104 can rotate after being powered on, thereby enabling the air to flow inside the flow guiding cylinder 101.
[0020] Furthermore, an isolation net 102 is fixedly installed on the side wall of the guide tube 101 at the position of the air inlet 103, and a gap is provided between the isolation net 102 and the side wall of the guide tube 101. The isolation net 102 can filter and protect the position of the air inlet 103. On the one hand, it can prevent a large number of impurities in the external environment from being sucked into the guide tube 101. On the other hand, it can divert rainwater in rainy weather, so that the rainwater falls from the isolation net 102 and avoids the rainwater being sucked into the air inlet 103. Moreover, by supplying power to the isolation net 102, the isolation net 102 can use its own electrostatic adsorption effect to improve the adsorption effect of dust and particulate matter in the air, further reducing the amount of dust sucked into the air inlet 103.
[0021] Furthermore, the monitoring component 4 includes a housing 403, the top diameter of which is larger than the bottom diameter, and the housing 403 is connected to the flow guiding component 1. A viewing window 404 is fixedly installed inside the housing 403. Two sets of exhaust holes 405 are provided on the side wall of the housing 403, and the two sets of exhaust holes 405 are respectively located near the top and bottom of the side wall of the housing 403. The exhaust holes 405 are both oriented diagonally downwards. Two sets of multispectral sensors 406 are installed facing away from each other inside the housing 403. The housing 403 can provide installation positions for surrounding components. The viewing window 404 is made of transparent material, allowing light to pass through, thus providing space for the multispectral sensors 406. 6. Providing monitoring conditions, the exhaust port 405 allows air inside the housing 403 to be discharged, thereby forming an air curtain above and below the viewing window 404, protecting the outer wall of the viewing window 404, reducing the probability of dust and impurities in the external environment coming into contact with the viewing window 404, thus ensuring that the viewing window 404 remains clean and preventing the viewing window 404 from being contaminated and affecting the monitoring effect of the multispectral sensor 406. The multispectral sensor 406 adopts the RedEdge-MX type. The multispectral sensor 406 can verify the authenticity of the solid-state lidar 401 data by identifying abnormal signals in the deformation area. The combination of the two can distinguish between real geological deformation and temporary interference, improving the accuracy of disaster early warning.
[0022] Furthermore, a top cover 407 is fixedly installed on the top of the housing 403, and an electromagnetic slide rail 402 is fixedly installed on the top of the top cover 407. A solid-state lidar 401 is slidably installed inside the electromagnetic slide rail 402. A cover 408 is fixedly installed above the electromagnetic slide rail 402, and a photovoltaic panel 409 is fixedly installed on the top of the cover 408. The top cover 407 protects the top of the housing 403 and provides a mounting position for the top components. The electromagnetic slide rail 402 allows the solid-state lidar 401 to move, enabling it to move along a circular path, thus expanding its monitoring range. The CH128 solid-state lidar 401 is used to perform three-dimensional scanning of the surrounding environment using lasers, thereby detecting subtle changes in the surrounding environment. This facilitates the monitoring of terrain changes within the mining area and helps detect potential landslides and collapses. The cover 408 provides top protection for the electromagnetic rail 402 and the solid-state lidar 401, preventing rainwater and snow from directly contacting and damaging them. The photovoltaic panel 409 converts solar energy into electrical energy, which then charges the battery 303 to power the electronic components inside the device.
[0023] Furthermore, several drainage cones are fixedly installed at the bottom edge of the top cover 407 and the cover 408. The bottom diameter of the drainage cones is smaller than the top diameter. The drainage cones allow rainwater on the top of the top cover 407 and the cover 408 to fall down along the drainage cones, thereby preventing rainwater from affecting the electromagnetic slide rail 402 and the solid-state lidar 401 between the top cover 407 and the cover 408.
[0024] Furthermore, the photovoltaic panel 409 is electrically connected to the main control box 302 and the battery 303 via cables.
[0025] Working principle: After the device is assembled, it is fixedly installed at a high point in the mining area with a relatively open view using bolts. Solar energy is converted by photovoltaic power generation panel 409 to provide power to battery 303, charging battery 303. The main control box 302 intelligently distributes the power inside battery 303 to power other electronic components inside the device. Multispectral sensor 406 monitors the vegetation, soil and water in the mining area. At the same time, after the electromagnetic slide rail 402 is powered on, it drives solid-state lidar 401 to move in a circular motion. Solid-state lidar 401 scans and monitors the three-dimensional terrain of the mining area by emitting and receiving lasers. Combining the detection data of solid-state lidar 401 and multispectral sensor 406, high-precision monitoring is carried out on potential landslides, collapses and other hidden danger areas in the mining area. During the monitoring process, the fan 104 drives air to enter the guide tube 101 through the air inlet 103, and then enters the housing 403 through the guide tube 101. The air after the housing 403 is then discharged from the two sets of exhaust holes 405 respectively, forming an air curtain on the upper and lower sides of the viewing window 404, and providing air cooling for the interior of the housing 403. As the air enters the guide tube 101 from the air inlet 103, the isolation net 102 is powered, causing the dust and light particles carried in the air to be adsorbed on the isolation net 102, so that relatively clean air enters the guide tube 101 separately, preventing dust accumulation inside the device.
