Description

Technical Field

[0001] The present invention relates to the technical field of geological disaster monitoring, and more specifically, to a device and method for geological disaster monitoring. Background Art

[0002] Geological disasters, such as landslides, mud-rock flows, collapses, etc., refer to geological actions or phenomena caused by natural or human factors, which cause loss of human life and property and damage to the environment. The distribution and change of geological disasters in time and space are both subject to the natural environment and related to human activities, and are often the result of the interaction between humans and nature. There are often some precursory phenomena before the occurrence of geological disasters, such as extremely large rainfall, abnormal changes in groundwater levels, irregular underground vibrations, and abnormal ground displacements. In order to reduce the losses caused by geological disasters, before a geological disaster occurs, the above-mentioned precursory phenomena are usually detected by a geological disaster monitoring device and the surveillance camera is triggered to monitor the surrounding environment in real time, so as to provide early warning, timely evacuate people and protect people's lives and property. Existing geological disaster monitoring devices often only detect a small number of parameters, with large monitoring errors, and are unable to accurately and timely warn of geological disasters. The surveillance camera is activated, and the geological disaster monitoring equipment is usually set up in the wild, where power supply is inconvenient. The surveillance camera continuously monitors or a small number of parameters are abnormal, which triggers the activation of the surveillance camera, which not only causes a waste of energy, but also seriously causes the geological disaster monitoring equipment to go on strike due to insufficient power supply.

[0003] For example, the invention patent with publication number CN117432906A discloses a geological disaster monitoring device, including a monitoring device body, a base, a support rod and a protective mechanism, wherein the support rod is arranged in the middle of the base, the monitoring device body is fixedly installed on the top of the support rod, and the protective mechanism is arranged around the base and covered on the outside of the support rod. The protective mechanism improves the protective effect above the monitoring device body, and at the same time, the support rod is set as a telescopic rod with variable length, so that the height of the monitoring device body installed on the top of the support rod can be changed, which not only avoids the monitoring device body being blocked during normal use and affects the sending and receiving of information, but also allows the monitoring device body to descend into the inner wall of the protective mechanism after the support rod is retracted, and improves the safety of the monitoring device body. In the above technical solution, although the safety of the monitoring device body is improved by setting a telescopic support rod and a protective mechanism, the monitoring device body is still in an uninterrupted monitoring mode, and the problem of high energy consumption of the geological disaster monitoring device cannot be solved.

[0004] Another example is the invention patent with publication number CN111256573A, which discloses a geological disaster monitoring device, including: a displacement metering belt, a sensor, a circuit conduction gate, a controller and a circuit, wherein the displacement metering belt is composed of an insulating belt and a metal conductor, the sensor is composed of a connecting ring box monitoring pile, more than three monitoring piles are provided, and the controller is electrically connected to a buzzer and a geological disaster prevention and control monitoring system through wires, and it feeds back displacement information to the displacement metering belt by providing more than three monitoring piles. Although the accuracy of displacement information detection is improved by providing more than three monitoring piles, the parameters for triggering the geological disaster prevention and control monitoring system are single, and it is easy to falsely report or miss the geological disaster warning signal, and it is impossible to warn geological disasters in a timely, reliable and accurate manner.

[0016] Other advantages, objectives and features of the present invention will be embodied in part through the following description, and in part will be understood by those skilled in the art through study and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0019] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0020] like Figure 1 , 2 As shown in Figure 3, the present invention provides a geological disaster monitoring device, including: The underground detection part includes an underground water level detection component inserted into the underground water layer to detect abnormal underground water level signals, and a vibration detection component symmetrically arranged on both sides of the underground water level detection component to detect abnormal underground vibration signals; The ground detection part includes a multi-point ground displacement detection component for detecting abnormal ground displacement signals at multiple fixed positions and a rainfall detection component for detecting abnormal rainfall signals; A disaster monitoring unit, which includes a monitoring component that captures video or image information within the monitoring area; The power supply control unit includes a solar panel 17, a battery 19 connected to the solar panel 17 through a photovoltaic controller, and a control box electrically connected to the battery 19. The control box controls the start and stop of the disaster monitoring unit according to the detection signals of the underground detection unit and the ground detection unit.

[0021] In the above technical scheme, the geological disaster monitoring device includes an underground detection part, an above-ground detection part, a disaster monitoring part and a power supply control part, wherein the power supply control part supplies power to the underground detection part, the above-ground detection part and the disaster monitoring part, and controls the start-up and shutdown of the disaster monitoring part according to the detection signals of the above-ground detection part and the underground detection part, and triggers the start-up and shutdown of the disaster monitoring part with the detection signals of the above-ground detection part and the underground detection part, thereby avoiding the following typical problems of geological disaster monitoring equipment: excessive energy consumption due to the uninterrupted monitoring of the disaster monitoring part, which ultimately leads to a mismatch between the power supply of its own solar panel and the energy consumption of the geological disaster monitoring device, causing the geological disaster monitoring device set up in the field to intermittently strike, affecting the timeliness and accuracy of geological disaster early warning.

[0022] In the above technical scheme, the underground detection part includes a groundwater level detection component and a vibration detection component, wherein the groundwater level detection component is inserted into the groundwater layer to detect abnormal groundwater level signals. Considering the cost of drilling downward, the geological disaster monitoring device provided by the present invention is preferably suitable for groundwater levels 15 to 20 meters away from the surface; the vibration detection component is inserted into the soil layer and the middle layer to detect abnormal underground vibration signals; the above-ground detection part includes a multi-point ground displacement detection component and a rainfall detection component, wherein the multi-point displacement detection component is arranged toward the ground to detect abnormal ground displacement signals at multiple different points; the rainfall detection component is arranged at a high place to detect abnormal rainfall signals. The above-ground detection part and the underground detection part collect multiple precursor parameter signals related to geological disasters, and use sufficient data to carry out geological disaster warnings, thereby improving the timeliness, reliability and accuracy of geological disaster warnings.

[0023] like Figure 1~2 As shown, in one of the technical solutions, the underground detection unit includes: A threading base plate 1, which is arranged on the ground; A groundwater level detection assembly, which is connected to the bottom of the threading base plate 1 and inserted into the groundwater layer, comprises a casing 2 with a hole at the bottom and a first water level sensor 3 arranged in the casing 2; A pair of vibration detection components are symmetrically arranged on both sides of the groundwater level detection component, and any vibration detection component includes a shallow vibration detection subassembly and a deep vibration detection subassembly, and the shallow vibration detection subassembly and the deep vibration detection subassembly are both connected to the bottom of the threading base plate 1 and inserted into the soil layer and the middle layer respectively; the shallow vibration detection subassembly and the deep vibration detection subassembly both include a protective tube and a vibration sensor arranged in the protective tube; the distance between a pair of shallow vibration detection subassemblies is greater than 25m, such as Figure 1 As shown, the shallow vibration detection subassembly includes a protection tube 8 and a first vibration sensor 6 disposed in the protection tube 8, and the deep vibration detection subassembly includes a protection tube and a second vibration sensor 7 disposed in the protection tube; Wherein, the threading base plate 1 is provided with threading holes facing the sleeve 2 and the protection tube 8 .

[0024] In the above technical scheme, the underground detection part includes a wire-threading base plate 1, an underground water level detection component arranged below the wire-threading base plate 1, and a pair of vibration detection components, wherein the wire-threading base plate 1 must ensure a certain load-bearing capacity and accommodate a certain space for the wires of each detection component and solar panel to pass through. Therefore, a preferred structure of the wire-threading base plate 1 includes a weight core arranged at a central position and a steel plate frame sleeved on the outer periphery of the weight core, wherein the weight core is at a certain distance from the bottom and the top of the steel plate frame to accommodate the passage of various wires; The groundwater level detection component includes a casing 2 inserted into the groundwater layer and a first water level sensor 3 arranged in the casing 2. The bottom of the casing 2 is provided with an opening to ensure that the groundwater level is flush with the water level in the casing. The first water level sensor 3 at least extends below the groundwater level to detect abnormal groundwater level signals. The average value of the groundwater level in the same period of the previous three years is used as the standard value. If the groundwater level fluctuates by more than ±2~5%, it means that the groundwater level is abnormal. The geology from top to bottom is soil layer, middle layer, aquifer and groundwater layer, among which the soil layer and middle layer are unsaturated areas, and the aquifer is contained. The water layer and the groundwater layer are saturated areas. The vibration detection components of the present invention are arranged in pairs on both sides of the groundwater level detection component. The vibration detection components on each side include a shallow vibration detection subcomponent arranged in the soil layer and a deep vibration detection subcomponent arranged in the middle layer. The deep vibration detection subcomponent is arranged close to the groundwater level detection component. The distance between a pair of shallow vibration detection subcomponents is greater than 25m. The passage of heavy trucks will cause vibrations in the soil layer. Studies have shown that the vibration caused by the passing of vehicles is severely attenuated after 10m from the vehicle in the horizontal direction. Generally, the length of heavy trucks does not exceed 12m, and the length of super-heavy trucks can reach 14m. The distance between a pair of shallow vibration detection subcomponents is greater than 25m. The vibration caused by heavy trucks cannot generally be detected by a pair of shallow vibration detection subcomponents at the same time, filtering out the adverse effects of the vibration caused by the passing of cars. The deep vibration detection subcomponent extends into the middle layer to detect abnormal vibrations at the underground depth. The vibration frequency can usually be set according to the on-site conditions (such as near a mine or near the sea), and the critical value of the vibration frequency can be set. If the critical value is exceeded, it is an abnormal signal. .

[0025] In the above technical scheme, when installing the geological disaster monitoring device, it is necessary to drill holes in advance according to the positions of the shallow vibration detection subassembly protection tube and the deep vibration detection subassembly protection tube of the casing 2. After the underground detection component, the vibration detection component and the threading base plate 1 are assembled, they can be hoisted to the preset position using hoisting equipment. Depending on the on-site environment, a cushion layer can be set between the threading base plate 1 and the ground to ensure the stability of the installation of the threading base plate 1. The threading base plate 1 is fixed to the ground through the protective tube of the vibration detection component and the casing of the groundwater level detection component, which ensures the overall stability of the geological disaster monitoring device and is suitable for harsh outdoor environments.

[0026] like Figure 1 and Figure 2 As shown, in one of the technical solutions, a mounting tube 4 is sleeved on the outer side of the ring of the sleeve 2, and a plurality of mounting grooves 41 are provided on the mounting tube 4, and a humidity sensor 5 for detecting soil humidity is provided in the mounting groove 41. There are a plurality of mounting grooves 41, so the abnormal signals detected by the plurality of humidity sensors 5 are valid signals when they are greater than or equal to half of the number of humidity sensors 5, and the plurality of abnormal signals are combined and recorded as soil humidity abnormal signals, and the average soil humidity of the same period of the previous three years is set as the standard value of soil humidity, and the soil humidity fluctuation exceeds ±1~3%, which is considered as soil humidity abnormality.

[0027] like Figure 1 and Figure 3 As shown, in one of the technical solutions, the ground detection unit includes: A first threading riser 18, which is arranged on the threading base plate 1 facing the shallow vibration detection subassembly; A second threading riser 20, which is arranged on the threading base plate 1 directly opposite to the deep vibration detection subassembly, and the height of the second threading riser 20 is higher than the height of the first threading riser 18; A V-shaped mounting plate 10, which is arranged on the first threading riser 18 through a connecting rod 9, and the opening surface of the V-shaped mounting plate 10 corresponds to the first threading riser 18; A multi-point displacement detection assembly, comprising two pairs of detection sleeve groups respectively arranged on two mounting plates of a V-shaped mounting plate 10, wherein each detection sleeve group comprises a pair of detection sleeves 101 arranged parallel and tilted downward and a support rod 102 connecting the detection sleeves, and a laser distance measuring sensor is arranged at the free end of each detection sleeve 101; A rainfall detection component, comprising a water storage outer box arranged between a pair of second threading risers 20 and a rainwater inlet 14 arranged on the top of the water storage outer box, wherein a water storage inner cylinder connected to the rainwater inlet 14 is arranged in the water storage outer box, a second water level sensor 13 and a third water level sensor 15 are arranged in the water storage inner cylinder to detect two water level critical values ​​in the water storage inner cylinder, and the installation height of the third water level sensor 15 is higher than that of the second water level sensor 13; a timing valve switch is arranged at the bottom of the water storage inner cylinder, and a drainage pipe is arranged on the side of the water storage outer box; A wire threading conduit 21, which connects the water storage inner cylinder and the second wire threading riser 20; Among them, a wire groove is set in the connecting rod 9, and the first wire threading riser 18 is provided with threading holes facing the connecting rod 9 and the threading base plate 1, so that the wires of the laser ranging sensor are sequentially inserted into the connecting rod 9, the first wire threading riser 18 and the threading base plate 1.

[0028] In the above technical scheme, the ground detection part includes a multi-point displacement detection component and a rainfall detection component, wherein the rainfall detection component is arranged at a high position, and the multi-point detection component is installed above the threading base plate 1 through the first threading riser 18. Preferably, the first threading riser 18 and the threading base plate 1 are directly opposite to each other and are provided with connected threading holes, so as to facilitate the wires passing through the first threading riser 18 to be passed into the threading base plate and finally connected to the control box. The multi-point displacement detection component can detect the ground displacement of multiple detection points at the same time, and the ground displacement greater than 0 is abnormal. The multi-point displacement detection component is arranged on the first threading riser 18 through the connecting rod 9. The first threading riser 18 is directly opposite to the shallow vibration detection sub-assembly protection tube. The first threading riser 18 is provided with a V-shaped mounting plate, and the V-shaped mounting plate includes two A V-shaped mounting plate is provided, and the multi-point displacement detection component is arranged on the V-shaped mounting plate. A pair of detection sleeves 101 arranged parallel to each other downward are provided on any mounting plate of the V-shaped mounting plate 10. A support rod 102 is connected between the pair of parallel detection sleeves 101 to support the detection sleeves 101. A laser ranging sensor is provided at the free end of any detection sleeve 101 to test the ground displacement value. Two pairs of detection sleeves 101 are arranged on the V-shaped mounting plate 1 and are also arranged in a V shape, so that the detection points of the four laser ranging sensors are different, and the ground displacement of multiple detection points is detected simultaneously, which is convenient for removing impurities from the ground displacement signal. When the number of ground displacement abnormal signals of multiple detection points is greater than or equal to 3, it is a valid signal, and the multiple ground displacement abnormal signals are merged into one signal, which is recorded as a surface displacement abnormal signal, otherwise it is an invalid signal.

[0029] In the above technical solution, the rainfall detection component is arranged between a pair of second threading risers 20, a closed box 16 is arranged between the pair of second threading risers 20, and the rainfall detection component is arranged above the closed box 16, which includes a water storage outer box, a rainwater inlet 14 arranged on the top of the water storage outer box, a water storage inner cylinder arranged in the water storage outer box and connected to the rainwater inlet 14, and a second water level sensor 13 and a third water level sensor 15 arranged in the water storage inner cylinder. The third water level sensor 15 is arranged higher than the second sensor 13. When it rains, rainwater passes through the rainwater inlet 14 (a filter plate is arranged at the rainwater inlet to prevent debris from entering). The sensor enters the water storage inner cylinder. If the amount of water in the water storage inner cylinder reaches the installation height of the second water level sensor 13 within the set time (i.e., reaches the critical value of the first rainfall warning), the first rainfall warning signal is detected. If the amount of water in the water storage inner cylinder reaches the installation height of the third water level sensor 15 within the set time (i.e., reaches the critical value of the second rainfall warning), the first rainfall warning signal and the second rainfall warning signal are detected successively. A timing valve switch is provided at the bottom of the water storage inner cylinder. After the set time, the timing valve switch is opened to quickly discharge the rainwater in the water storage inner cylinder, and the timing valve switch is closed to enter the next cycle of detection. In the present invention, the incomplete removal of rainwater from the water storage inner cylinder does not affect the accurate triggering of the monitoring signal. The wires of the second sensor 13 and the third sensor 15 are connected to the control box via the threading conduit 21 and the second threading riser 20.

[0030] In the above technical solution, both the first wire threading riser 18 and the second wire threading riser 20 need to have a certain bearing capacity. Therefore, both the first wire threading riser 18 and the second wire threading riser 20 have a load-bearing core to ensure the bearing capacity of the first wire threading riser 18 and the second wire threading riser 20. In the geological monitoring device provided by the present invention, the control box completes electrical connection and data transmission through wires with both the above-ground detection part and the underground detection part, thereby avoiding failure of wireless communication in the field environment and affecting the timeliness of geological disaster warning.

Any first-level warning signal or any second-level warning signal triggers the start-up of the fixed surveillance camera; the combination of at least two warning signals, one of which is a second-level warning signal, triggers the start-up of the rotating surveillance camera group.

[0032] In the above technical solution, the disaster monitoring unit is arranged in the middle and upper part of the second wire threading riser 20 on one side away from the rainfall detection component, and includes a fixed monitoring camera 11 arranged on the side of the second wire threading riser 20 and a rotating monitoring camera group 12 arranged above the fixed monitoring camera 11. The fixed monitoring camera 11 is arranged in the direction where geological disasters may occur. For example, when monitoring landslides, the geological disaster monitoring device is arranged at the foot of the mountain, and the fixed monitoring camera is arranged in the direction of the mountain to monitor the scenes on both sides of the rainfall detection component. The rotating monitoring camera group 12 is rotatably installed above the fixed monitoring camera 11. One implementation method is as follows: a first column is provided on the top of the fixed monitoring camera, and a bearing is provided on the top of the first column. A second column is provided on the top of the rotating monitoring camera group 12, and a driven gear is provided on the outer periphery of the second column. The second column is connected to the bearing of the first column, and the driven gear is meshed with a main gear. The main gear is driven by a motor, and the motor is electrically connected to the control box. Figure 1 In the embodiment, the camera of the rotating monitoring camera group 12 is located on the same side as the fixed monitoring camera. The rotation speed of the rotating monitoring camera group 12 does not affect the clarity of the monitoring video or image. During the rotation, the rotating monitoring camera group monitors the scene around the geological disaster monitoring device. The disaster monitoring unit in the geological disaster monitoring device disclosed in the present invention adopts a combination of a fixed monitoring camera 11 and a rotating monitoring camera group 12, which monitors the scene around the geological disaster monitoring device in all directions, and provides a basis for geological disaster early warning in a timely, reliable and accurate manner.

[0034] In one of the technical solutions, the power supply control unit includes: A solar panel 17, which is obliquely installed between the first wire threading riser 18 and the second wire threading riser 20, and the solar panel 17 is located below the fixed surveillance camera 11; A closed box 16 is arranged between a pair of second wire threading risers 20 and below the water storage outer box. A battery 19 and a control box electrically connected to the battery 19 are arranged in the closed box 16. The solar panel 17 is electrically connected to the battery 19 through a photovoltaic controller. The control box is electrically connected to the groundwater level detection component, the vibration detection component, the rainfall detection component and the multi-point displacement detection component.

[0035] In the above technical scheme, the power supply control unit is used to supply power to the entire geological disaster monitoring device, receive data feedback from each detection component and control the startup and shutdown of the disaster monitoring unit. The power supply control unit is arranged in a closed box 16, which fully protects the photovoltaic controller, battery and control box of the power supply control unit, and improves the service life of the entire geological disaster monitoring device in the field. Another function of the closed box 16 is to serve as the base of the rainfall detection component, increase the setting height of the rainfall detection component, and prevent other components from having an adverse effect on the collection of rainfall.

[0036] In the above technical scheme, the geological disaster monitoring device provided by the present invention adopts solar panels 17 to power the entire system. After accurately controlling the trigger mechanism of the disaster monitoring unit, there are two solar panels 17 obliquely arranged between the first threading riser 18 and the second threading riser 20. The power supply is sufficient to supply the use of the entire geological disaster monitoring device, solving the problem of difficulty in powering the geological disaster monitoring device in the field.

[0037] The present invention further claims protection for a monitoring method of the geological disaster monitoring device, comprising: The first step is signal acquisition: the first water level sensor 3 is used to obtain the abnormal groundwater level signal, the humidity sensor 5 is used to obtain the abnormal soil moisture signal, the four vibration sensors are used to obtain two shallow vibration abnormal signals and two deep vibration abnormal signals, the multiple laser ranging sensors are used to obtain multiple ground displacement abnormal signals, the second water level sensor 13 is used to obtain the first rainfall warning signal, and the third water level sensor 15 is used to obtain the second rainfall warning signal. Step 2: Signal removal: when the number of abnormal ground displacement signals is greater than or equal to 3, it is a valid signal, and multiple abnormal ground displacement signals are merged into one signal, which is defined as a surface displacement abnormal signal, otherwise it is an invalid signal; when the number of abnormal shallow vibration signals is 2, it is a valid signal, and two abnormal shallow vibration signals are merged into one signal, which is defined as a shallow vibration abnormal signal, otherwise it is an invalid signal; when the number of abnormal soil moisture data is greater than or equal to 3, it is a valid signal, and multiple abnormal soil moisture signals are merged into one signal, which is defined as an underground soil moisture abnormal signal, otherwise it is an invalid signal; Step 3: Signal integration: mark the first rainfall warning signal, shallow vibration abnormal signal, and underground soil moisture abnormal signal as the first-level warning signal, and the surface displacement abnormal signal, groundwater level abnormal signal, two deep vibration abnormal signals, and the second rainfall warning signal as the second-level warning signal; Step 4, signal triggering: any level 1 warning signal or any level 2 warning signal triggers the start of the fixed surveillance camera 11; a combination of at least two warning signals, one of which is a level 2 warning signal, triggers the start of the rotating surveillance camera group 12.

[0038] In the above technical scheme, the monitoring method includes signal acquisition, signal de-cluttering, signal integration and signal triggering processes. In the signal acquisition process, multiple sensors are used to collect as much field data as possible. The richer the data, the more timely, reliable and accurate the geological disaster warning is. In the signal de-cluttering process, some interfering and accidental data should be removed, and the rich data should be classified and processed in a refined manner, such as accidental data in multiple ground displacement anomaly signals and local unreliable data in multiple soil moisture anomaly data. In the signal integration process, the first rainfall warning signal, the shallow vibration anomaly signal, and the soil moisture anomaly signal are classified as the first-level warning signal, and the surface displacement anomaly signal, the groundwater level anomaly signal, the two deep vibration anomaly signals and the second rainfall warning signal are classified as the second-level warning signal. In the signal triggering process, both the first-level warning signal and the second-level warning signal can trigger the start of the fixed monitoring camera, and the triggering of the rotating monitoring camera group must include a second-level warning signal. The monitoring method adheres to the principle of broad detection and strict control of triggering, which greatly improves the reliability of geological disaster warning.

[0039] The number of devices and processing scales described here are used to simplify the description of the present invention. The application, modification and variation of the geological disaster monitoring device and method of the present invention are obvious to those skilled in the art.

[0040] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes, and they can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
