Description

Technical Field

[0001] This invention relates to the field of environmental monitoring technology, specifically to a flash flood early warning device based on GNSS areal rainfall monitoring. Background Technology

[0002] The BeiDou Navigation Satellite System, independently developed by my country, boasts advantages such as high precision, all-weather capability, and all-time operation, providing strong technical support for meteorological monitoring and forecasting. Rainfall measurement systems based on BeiDou technology can collect, process, and transmit precipitation data in real time, enabling real-time monitoring and early warning of precipitation conditions, and providing scientific basis for meteorological forecasting, flood control and drought relief, and urban drainage.

[0003] Existing environmental monitoring base stations consist of traditional poles with various sensors, power supplies, RTUs, and other equipment mounted on them. These devices come from different manufacturers, requiring interface integration and compatibility, making installation and debugging complex, and necessitating individual installation for each sensor and device. Furthermore, the poles, power supplies, RTUs, and ground cages require separate construction. The sensors are constantly exposed to the elements, necessitating regular, individual inspections of each device, resulting in high maintenance costs and difficulties. Additionally, environmental factors, such as rain or high humidity, can easily damage the internal motherboards of the monitoring equipment, affecting its normal operation. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a flash flood early warning device based on GNSS areal rainfall monitoring to solve the problems mentioned in the background section. To achieve the above objectives, the present invention provides the following technical solution: a flash flood early warning device based on GNSS areal rainfall monitoring, comprising: a base, a cable guide fixed at the top center of the base, a monitoring device fixed at the upper end of the cable guide, wrapping assemblies on the left and right sides of the base located on the monitoring device, and drive assemblies on the front and rear sides of the base; a cable passes through the cable guide and is electrically connected to the monitoring device; the wrapping assembly includes side plates, two sets of which are rotatably mounted on the base on both sides of the monitoring device, and rotating plates are rotatably mounted on both sides of the side plates via a rotating shaft and a torsion spring, the side plates and rotating plates being combined into a square wrapping frame, the monitoring device being located inside the wrapping frame; a cavity is provided inside the side plate, and a porous moisture-absorbing plate is fixed in the middle of the cavity; the drive assembly includes a gear, a gear is fixed at one end of the rotating shaft of the side plate and the base, and a toothed plate is meshed with the bottom of the gear.

[0005] Furthermore, the drive assembly also includes: a first bidirectional electric push rod, a movable frame, and a right-angle frame. The first bidirectional electric push rod is fixed inside the base in a direction perpendicular to the two side plates, and the extended end of the first bidirectional electric push rod protrudes from the base and is fixed to the movable frame. The two ends of the movable frame are fixed to the right-angle frame, and the top of the right-angle frame is in contact with the outer surface of the rotating plate of the two side plates. When the side plates are rotated to a horizontal position, the right-angle frame pushes the rotating plate to rotate and fold onto the inner surface of the side plates.

[0006] Furthermore, a hot air blower is installed at the bottom of the two right-angled frames on the base, and an insertion tube is fixed at the bottom of the right-angled frame. The other end of the insertion tube is fixedly connected to the air outlet of the hot air blower inside the base through a corrugated pipe. The side plate has an insertion hole corresponding to the position of the insertion tube, and the insertion hole is located on one side of the bottom of the porous moisture-absorbing plate.

[0007] Furthermore, the packaging assembly also includes: an air outlet, a first drainage groove, and a second drainage groove. The second drainage groove is equidistantly provided on the side of the side plate facing outward, and the first drainage groove is equidistantly provided on the side of the side plate facing the monitoring device. An air outlet is equidistantly provided on the end of the side plate away from the rotatably connected base, and the air outlet is located at the upper end of the porous moisture-absorbing plate. Heat dissipation windows are provided on both sides of the monitoring device corresponding to the positions of the first drainage grooves, and a cooling fan is installed inside the heat dissipation windows.

[0008] Furthermore, a sealing strip is sealed and inserted into each second groove of the side plate, a connecting frame is fixed to the outside of the sealing strip, and a return spring is fixed at equal intervals on the surface of the connecting frame, and the other end of the return spring is fixedly connected to the surface of the side plate; wherein, baffles are fixed on both sides of the base at the bottom of the side plate, and abutments are fixed on the connecting frame at the positions corresponding to the baffles.

[0009] Furthermore, limit frames are fixed on both sides of the side plate away from the end rotatably connected to the base, and the limit frames are in contact with the outer surface of the rotating plate: wherein the rotating plate is in contact with the limit frames after rotating 90 degrees.

[0010] Furthermore, a second bidirectional electric push rod is fixed to the top of the first bidirectional electric push rod protruding end of the base, and the extended end of the second bidirectional electric push rod is fixedly connected to the toothed plate; wherein, the toothed plate is moved by the second bidirectional electric push rod, thereby rotating the side plate into a vertical or horizontal position.

[0011] Furthermore, the top of the monitoring device is fixed with a top plate, and the side plate and the rotating plate form a sealed box structure with the top plate; wherein, when the side plate and the rotating plate are vertical, they slide in contact with the bottom of the top plate, and a sealing ring is provided at the bottom of the top plate corresponding to the contact position of the side plate and the rotating plate.

[0012] Furthermore, a photovoltaic panel is installed on the outer surface of the rotating plate, and a detection end is fixedly installed on the top of the monitoring device, with a high-precision environmental sensor installed inside the detection end.

[0013] Furthermore, a drainage groove is provided on the top of the base at the front and rear ends of the monitoring device, and the shielding range of the top plate extends beyond the square frame formed by the combination of the side plate and the rotating plate.

[0014] The beneficial effects of this invention are: 1. This invention uses a second bidirectional electric push rod to move the toothed plates on both sides, causing the toothed plates to mesh with gears, thereby rotating the side plates. The side plates can be rotated vertically to enclose the monitoring device, providing protection against rain and moisture. Under normal weather conditions, the side plates rotate horizontally, facilitating the regeneration of the porous moisture-absorbing plate inside the side plates. When the rotating plate rotates, the first electric push rod moves the moving frame and the right-angle frame away from the side plates, so that the rotating plate automatically opens when the side plates rotate vertically. When the side plates rotate horizontally, the first electric push rod moves the right-angle frame to press the rotating plate, and the rotating plate covers the first groove of the side plates, sealing the first groove. At the same time, as the right-angle frame moves, the insertion tube is inserted into the insertion hole, and hot air is blown into the side plates by a hot air blower, flowing out from inside the porous moisture-absorbing plate and out through the air outlet.

[0015] 2. When the side plate is vertical, the sealing strip and connecting frame move away from the second trough via a return spring. At this time, air enters the enclosed space through the second trough, the porous moisture-absorbing plate, and the first trough, providing heat dissipation for the monitoring device while protecting it from rain and moisture. When the side plate rotates to a vertical position, the connecting frame's abutment contacts the baffle, causing the connecting frame and sealing strip to move and insert into the second trough, sealing its position. As the insertion tube is inserted into the side plate, the porous moisture-absorbing plate inside is dried and regenerated by air blowing, preventing air from flowing out of the first and second troughs and allowing it to flow out only through the air outlet. This maintains efficient and uniform airflow to the porous moisture-absorbing plate. The heat dissipation windows and cooling fans on both sides of the monitoring device provide air intake and exhaust, working in conjunction with the side plate to maintain air circulation.

[0016] 3. In this invention, after the right-angle frame leaves the top of the rotating plate, the rotating plate flips open due to the elastic force of the torsion spring. At this time, it is limited by the limiting frame, and the maximum rotation angle is ninety degrees. Thus, when the side plate rotates to a vertical position, the enclosure frame formed by the side plate and the rotating plate protects the internal monitoring device.

[0017] 4. When the side panels are in a vertical state, the side panels automatically unfold and merge into a box-like structure. The top panel prevents rainwater from flowing into the interior from the top, and the drainage groove on the base drains the rainwater accumulated on the base. The photovoltaic panels on the rotating plate can power the equipment. Using existing photovoltaic power generation technology, when the side panels are vertical, the photovoltaic panels on the rotating plate face outwards and can generate photovoltaic power. After the side panels are rotated and opened, the side panels are covered by the right-angle frame. At this time, the photovoltaic panels are also facing upwards and can still generate photovoltaic power. This process is synchronized with the drying and regeneration of the porous moisture-absorbing plate inside the side panels.

[0018] 5. The monitoring device of this invention integrates a deep learning artificial intelligence algorithm model, enabling real-time rainfall reporting and hourly weather forecasts for a range of 1-20 square kilometers above a single GNSS monitoring station. It solves the problems of short-term rainfall forecasting and real-time rainfall monitoring within a specific area and can be widely applied in meteorology, hydrology, natural resources, emergency response, scientific research, and other fields.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 and Figure 10As shown, this disclosure proposes a flash flood early warning device based on GNSS areal rainfall monitoring, comprising: a base 1, a cable guide 34 fixed at the top center of the base 1, a monitoring device 3 fixed at the upper end of the cable guide 34, wrapping components 2 on the left and right sides of the base 1 located on the monitoring device 3, and driving components 4 on the front and rear sides of the base 1; a cable passes through the cable guide 34 and is electrically connected to the monitoring device 3; the wrapping components 2 include side plates 21, two sets of which are rotatably mounted on the base 1 on both sides of the monitoring device 3, and rotating plates 24 are rotatably mounted on both sides of the side plates 21 via a rotating shaft and a torsion spring; the side plates 21 and the rotating plates 24 are combined in a square wrapping frame. The monitoring device 3 is located inside the packaging frame; the side plate 21 has a cavity inside, and a porous moisture-absorbing plate 212 is fixed in the middle of the cavity of the side plate 21; the drive assembly 4 includes a gear 47, and the gear 47 is fixed at one end of the rotation shaft of the side plate 21 and the base 1. The bottom of the gear 47 is meshed with a toothed plate 46. When using the device, the base 1 is fixed in an open and flat area to ensure that the top is not obstructed. The monitoring device 3 monitors the environment and rainfall. In rainy environments or under conditions of high air humidity, the packaging assembly 2 and the drive assembly 4 wrap and protect the monitoring device 3 and absorb moisture in the air to avoid damaging the internal main circuit of the monitoring device 3. The information of all monitoring devices 3 in the jurisdiction is managed in a unified manner. Through the spatial positioning function of GIS, the specific location and working status of each rainfall monitoring station can be viewed intuitively, including the total number and zonal distribution of monitoring devices 3, the number and online status of IoT devices, the trend changes of key monitoring indicators, the latest reported monitoring data, etc. The temperature, humidity, pressure and wind meteorological sensors monitor and collect meteorological information near the stations in real time. Using a data-driven model based on deep learning, the coupling relationship between meteorological parameters and target rainfall events is learned and fitted by training a large amount of long-term meteorological parameter data, so as to realize short-term nearby rainfall prediction. The foundational support layer forms the basic operating environment for the system, encompassing both the network and hardware platforms. The hardware primarily consists of the hardware modules of the GNSS areal rainfall monitor, including GNSS signal receiving modules, meteorological sensors, high-precision rain gauges, power supply modules, antenna modules, and data processing modules. The network environment the system relies on mainly includes satellite communication networks, wireless communication networks, government networks, and the internet. The data processing and service layer primarily provides data aggregation, data processing, and data services. Data reception and processing are achieved by installing data processing modules on device terminals, including navigation satellite processing modules, meteorological data analysis modules, and water vapor data analysis modules. The processed data is then transmitted to a cloud server, utilizing existing next-generation information network technologies. The system provides mobile telecommunications services such as the construction and networking of mobile communication core networks and access networks; Z-Wave and wireless networking; and other telecommunications services such as mobile voice services and mobile data communication services. The cloud server receives and processes data through IoT communication modules and stores it in a cloud database. Simultaneously, it utilizes AI models for deep learning to predict areal rainfall, publishing relevant forecast data as services for the application service layer. The application service layer, aligned with the project's goals and tasks, develops functional modules for GNSS areal rainfall equipment management, equipment group management, integrated monitoring, report generation, and forecast detection. It also integrates with the Jingchu Reservoir platform to provide relevant forecast services for the reservoir platform to access.

[0022] The monitoring and early warning solution, based on artificial intelligence and GNSS technology, collects real-time information on rainfall and other elements, comprehensively improving the ability to thoroughly perceive information on flash floods, providing accurate forecasts and early warnings. Real-time data fusion, mining, and analysis, along with 3D simulation, comprehensively enhance the ability to thoroughly perceive hydrological information, truly realizing the digital twinning of hydrological stations. The monitoring device integrates a deep learning artificial intelligence algorithm model, enabling real-time rainfall reporting and hourly weather forecasts (1-12 hours) within a 1-20 square kilometer area above a single GNSS monitoring station. It solves the problem of short-term and hourly rainfall forecasts and real-time rainfall monitoring within specific areas, and can be widely applied in meteorology, hydrology, natural resources, emergency response, scientific research, and other fields. The monitoring station provides flexible device access methods; user devices can access the platform based on mainstream protocols such as CoAP and MQTT, enabling device management, device shadowing, message communication, and other functions. Simultaneously, it connects to rich cloud service components and resources, creating a full-site service encompassing data collection, storage, and computation for multiple sensing and monitoring scenarios. Off-site devices access the cloud platform via the MQTT protocol and can forward data through a rules engine. The GNSS areal rainfall monitoring and forecasting system publishes the forecasts and information generated by the system to the cloud via the Internet, enabling users to view them in real time and visualize the products. The performance evaluation of the equipment forecasts references industry standards such as the "Methods for Quality Inspection of Medium and Short-Term Weather Forecasts" and the "River Basin Areal Rainfall Levels" commonly used by meteorological departments. Based on the magnitude and forecast level of areal rainfall forecasts, the system comprehensively evaluates the equipment forecast performance through multi-dimensional scoring standards such as TS score, FAR false alarm rate, PO false alarm rate, and RMSE root mean square error. By comparing with reference rain gauges near the station and mainstream numerical model forecast grid products, the system comprehensively evaluates the single-station forecast effect and network forecast performance of monitoring device 3.

[0023] Achieving comprehensive monitoring capabilities: By integrating advanced BeiDou satellite navigation technology and meteorological monitoring equipment, the system enables real-time monitoring and accurate forecasting of rainfall. The system should be able to display the real-time status of equipment stations, rainfall distribution, and rainfall forecasts for the next three hours, providing users with intuitive rainfall information.

[0024] Improve forecast verification accuracy: Provide administrators with a forecast verification module to calculate key forecast verification indicators, such as TS, BS, FAR, and PO, by comparing forecasts with actual rainfall to evaluate the accuracy and reliability of the forecast model. Simultaneously, provide visual charts to facilitate in-depth analysis of forecast performance by administrators.

[0025] Improve historical data query functionality: Establish a comprehensive historical database, supporting users to query historical rainfall data by date, station, and other criteria. The system should provide diverse data display methods, such as line charts and tables, and allow users to export data for further analysis and research.

[0026] Optimize report generation and export: The system should provide a flexible and easy-to-use report generation module, supporting users to generate different types of reports according to their needs, such as daily reports, monthly reports, emergency reports, and daily rainfall comparison reports. Report content should include early warning information release details, rainfall statistics, and visual charts. All reports should support export functionality for easy sharing and saving by users.

[0027] Enhanced system management functions: A comprehensive system management module is built to achieve full management of multi-dimensional information such as users, devices, and organizations. The system supports functions such as user permission management, device status monitoring, and organizational information maintenance, ensuring efficient system operation and data security.

[0028] Improved early warning response speed: Monitoring device 3 is equipped with an early warning module, enabling real-time dissemination and response to rainfall warnings. The system should be able to automatically trigger warnings based on set thresholds and send warning information to relevant users. Simultaneously, it should provide convenient query and filtering functions to help users quickly locate and process warning information.

[0029] Enhanced system flexibility and scalability: The system adopts a modular design, facilitating subsequent functional expansion and upgrades. It also provides a flexible filtering module, allowing users to select the display devices, features, and layers according to their needs, catering to the usage habits and requirements of different users.

[0030] The cloud platform for rainfall and flood warning and forecasting utilizes advanced monitoring technology and data analysis algorithms to provide refined forecasts of rainfall and flood conditions within the reservoir area. By deploying a dense network of monitoring stations around the reservoir, it collects key data such as rainfall and water levels in real time. Combined with meteorological forecasts, the platform uses machine learning and deep learning algorithms to process and analyze the data, achieving accurate predictions of rainfall and flood conditions within the area. This refined forecasting not only improves the accuracy and timeliness of forecasts but also provides a more scientific and reliable basis for reservoir management decisions. The platform has the function of real-time monitoring and early warning of reservoir rainfall. Through real-time data collection and transmission from monitoring stations, the platform can grasp the reservoir's rainfall situation in real time, including key information such as rainfall amount, rainfall intensity, and rainfall duration. When rainfall reaches or exceeds a preset threshold, the platform automatically triggers an early warning mechanism, sending warning information to management personnel to remind them to take necessary preventative measures to ensure reservoir safety. The platform also has the function of conducting risk assessments of reservoir precipitation. By comprehensively analyzing multi-source information such as historical rainfall data, reservoir topography, and hydrological characteristics, the platform can assess the rainfall risk of reservoirs under different rainfall conditions. This risk assessment not only helps managers understand the potential risks the reservoir may face in advance but also provides a scientific basis for developing targeted preventative measures. The platform supports full-process 3D visualization of digital reservoir twin scenarios. Utilizing digital twin technology, the platform can construct virtual models highly similar to real reservoirs, including key elements such as topography, hydrological characteristics, and structures. Managers can browse and view the digital reservoir from all angles through the platform, achieving real-time monitoring and dynamic management of the reservoir's operational status. Furthermore, the platform supports simulation and extrapolation of digital reservoirs, helping managers better understand the reservoir's operational patterns and potential risks. The platform has a full-process simulation function for reservoir flood evolution. By utilizing advanced technologies such as hydrodynamic models and GIS, the platform can simulate the evolution of reservoir floods under different rainfall conditions, including key information such as flood inundation range, inundation depth, and flow velocity. This simulation not only helps managers understand the potential impact and hazards of floods in advance, but also provides a scientific basis for formulating effective flood prevention and disaster reduction measures. The plan utilizes visualization to extract key information elements and present them through a visual interface. For example, information such as the inundation area, villages within the inundation area, surrounding rescue teams, nearby warehouses, rescue routes, and evacuation routes can be directly and intuitively displayed through a 3D map interface. Detailed information about the plan, the evacuation of residents, and information on relief supplies can be presented intuitively through text.

[0031] like Figure 4 , Figure 5 and Figure 6As shown, in some embodiments, the drive assembly 4 further includes: a first bidirectional electric push rod 41, a movable frame 42, and a right-angle frame 43. The first bidirectional electric push rod 41 is fixed inside the base 1 in a direction perpendicular to the two side plates 21, and the extended end of the first bidirectional electric push rod 41 protrudes from the base 1 and is fixed to the movable frame 42. The two ends of the movable frame 42 are fixed to the right-angle frame 43, and the top of the right-angle frame 43 is in contact with the outer surface of the rotating plate 24 of the two side plates 21. When the side plates 21 are rotated to a horizontal position, the right-angle frame 43 pushes the rotating plate 24 to rotate and fold onto the inner surface of the side plates 21. The base 1 is located at the bottom of the two right-angle frames 43. A hot air blower is installed in the part, and an insertion tube 44 is fixed at the bottom of the right-angle frame 43. The other end of the insertion tube 44 is fixedly connected to the air outlet of the hot air blower inside the base 1 through a corrugated pipe. The side plate 21 has an insertion hole 210 on the side corresponding to the position of the insertion tube 44. The insertion hole 210 is located on one side of the bottom of the porous moisture-absorbing plate 212. The base 1 is fixed at the top of the protruding end of the first bidirectional electric push rod 41 with a second bidirectional electric push rod 45, and the extended end of the second bidirectional electric push rod 45 is fixedly connected to the toothed plate 46. The second bidirectional electric push rod 45 drives the toothed plate 46 to move, thereby rotating the side plate 21 to a vertical or horizontal position.

[0032] Understandably, the second bidirectional electric push rod 45 drives the two side toothed plates 46 to move, causing the toothed plates 46 to mesh with the gears 47, thereby driving the side plate 21 to rotate. This allows the side plate 21 to rotate vertically to enclose the monitoring device 3, providing protection against rain and moisture. Under normal weather conditions, the side plate 21 rotates horizontally, facilitating the regeneration of the porous moisture-absorbing plate 212 inside the side plate 21. When the rotating plate 24 rotates, the first electric push rod drives the moving frame 42 and the right-angle frame 43 away from the side plate 21, so that when the side plate 21 rotates vertically, the rotating plate 24 automatically opens. When the movement is horizontal, the first electric push rod drives the right-angle frame 43 to move and squeeze the rotating plate 24. The rotating plate 24 covers the first groove 23 of the side plate 21 to seal the first groove 23. At the same time, as the right-angle frame 43 moves, the insertion tube 44 is inserted into the insertion hole 210. Hot air is blown into the side plate 21 by the hot air blower and flows out from the porous moisture-absorbing plate 212 and out through the air outlet 22. The regeneration principle of the porous moisture-absorbing plate 212 in this part of the technology is based on metal-organic frameworks (MOFs): a new type of porous material with a large specific surface area. Some types can be rapidly regenerated at a low temperature (<100℃).

[0033] like Figure 4 , Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, in some embodiments, the packaging assembly 2 further includes: an air outlet 22, a first drainage groove 23, and a second drainage groove 27. The side plate 21 has the second drainage groove 27 equidistantly spaced on its outward-facing side, and the side plate 21 has the first drainage groove 23 equidistantly spaced on its side facing the monitoring device 3. The side plate 21 has the air outlet 22 equidistantly spaced at its end away from the end rotatably connected to the base 1, and the air outlet 22 is located at the upper end of the porous moisture-absorbing plate 212. The monitoring device 3 has air outlets on both sides corresponding to the positions of the first drainage grooves 23. The device is provided with a heat dissipation window 33, and a heat dissipation fan is installed inside the heat dissipation window 33. A sealing strip 26 is sealed and inserted into each second groove 27 of the side plate 21. A connecting frame 25 is fixed to the outside of the sealing strip 26. A return spring 211 is fixed at equal intervals on the surface of the connecting frame 25, and the other end of the return spring 211 is fixedly connected to the surface of the side plate 21. Baffles 12 are fixed on both sides of the base 1 at the bottom of the side plate 21. A stop post 28 is fixed on the connecting frame 25 at the position corresponding to the baffle 12.

[0034] Understandably, when the side plate 21 is vertical, the sealing strip 26 and the connecting frame 25 leave the second trough 27 via the return spring 211. At this time, air enters the enclosed space through the second trough 27, the porous moisture-absorbing plate 212, and the first trough 23, providing heat dissipation for the monitoring device 3 while also protecting it from rain and moisture. When the side plate 21 rotates to a vertical position, the abutment 28 of the connecting frame 25 presses against the baffle 12, causing the connecting frame 25 and the sealing strip 26 to move and insert into the second trough. Inside 27, the position of the second trough 27 is sealed. At this time, as the insertion tube 44 is inserted into the side plate 21, the porous moisture-absorbing plate 212 inside is dried and regenerated by blowing air. At the same time, air is prevented from flowing out from the first trough 23 and the second trough 27, and can only flow out from the air outlet 22, so as to maintain efficient and uniform air blowing on the porous moisture-absorbing plate 212. The heat dissipation window 33 and the heat dissipation fan on both sides of the monitoring device 3 are for air intake and air exhaust respectively, so as to cooperate with the side plate 21 to perform the function of air intake and air exhaust, and maintain air circulation.

[0035] like Figure 6 and Figure 8 As shown, in some embodiments, the side plate 21 is fixed with limit frames 29 on both sides away from the end rotatably connected to the base 1, and the limit frames 29 are in contact with the outer surface of the rotating plate 24: wherein the rotating plate 24 is in contact with the limit frames 29 after rotating ninety degrees.

[0036] It should be noted that after the right-angle frame 43 leaves the top of the rotating plate 24, the rotating plate 24 flips open due to the elastic force of the torsion spring. At this time, it is limited by the limit frame 29, and the maximum rotation angle is ninety degrees. Thus, when the side plate 21 rotates to a vertical position, the enclosure frame formed by the side plate 21 and the rotating plate 24 protects the monitoring device 3 inside.

[0037] like Figure 1 , Figure 3 and Figure 5 As shown, in some embodiments, the top of the monitoring device 3 is fixed with a top plate 31, and the side plate 21 and the rotating plate 24 form a sealed box structure with the top plate 31; wherein, when the side plate 21 and the rotating plate 24 are vertical, they slide in contact with the bottom of the top plate 31, and a sealing ring is provided at the bottom of the top plate 31 corresponding to the contact position of the side plate 21 and the rotating plate 24; a photovoltaic panel is installed on the outer surface of the rotating plate 24; a detection end 32 is fixedly provided on the top of the monitoring device 3; a high-precision environmental sensor is provided inside the detection end 32; a drainage groove 11 is provided on the top of the base 1 at the front and rear ends of the monitoring device 3; and the shading range of the top plate 31 exceeds the square frame formed by the combination of the side plate 21 and the rotating plate 24.

[0038] It should be noted that when the side panel 21 is in a vertical state, it automatically unfolds and merges into a box-like structure. The top panel 31 prevents rainwater from flowing into the interior from the top, and the drainage channel 11 on the base 1 drains the rainwater accumulated on the base 1. The photovoltaic panels on the rotating plate 24 can power the equipment. Using existing photovoltaic power generation technology, when the side panel 21 is vertical, the photovoltaic panels on the rotating plate 24 face outwards, enabling photovoltaic power generation. After the side panel 21 is rotated and opened, it is pressed by the right-angle frame 43, covering the side panel 21. At this time, the photovoltaic panels also face upwards, still enabling photovoltaic power generation, in conjunction with the drying and regeneration of the side panel 21. Simultaneously, the porous moisture-absorbing plate 212 of the department is used. The high-precision environmental sensor detects environmental humidity, temperature, rainfall, wind speed, and wind direction. After processing by the local data management system, the data is uploaded to the cloud for subsequent inversion and prediction. Combined with machine learning methods, the system mines the patterns of historical data in the cloud and performs deep learning to predict areal rainfall with an accuracy of 3mm in a radius of 2-3 kilometers in real time or 1-12 hours in advance. This achieves high-precision, high-efficiency, timely and accurate real-time monitoring and forecasting of areal rainfall. The information and forecasts obtained from the system's inversion calculation are published to the cloud via the Internet so that users can view the areal rainfall forecast in real time.

[0039] Working principle: When using the device, fix the base 1 in an open and flat area, ensuring that the top is unobstructed. The monitoring device 3 monitors the environment and rainfall. In rainy conditions or when air humidity is high, the enclosure component 2 and drive component 4 enclose and protect the monitoring device 3, and absorb moisture from the air to prevent damage to the internal mainboard circuitry of the monitoring device 3. Information from all monitoring devices 3 within the jurisdiction is managed uniformly. The second bidirectional electric push rod 45 moves the two side toothed plates 46, causing them to mesh with the gears 47, which in turn rotates the side plate 21. This allows the side plate 21 to rotate vertically to enclose the monitoring device 3, providing protection against rain and moisture. Under normal weather conditions, the side plate 21 rotates horizontally, facilitating operation. The porous moisture-absorbing plate 212 inside undergoes regeneration processing. When the rotating plate 24 rotates, the first electric push rod drives the moving frame 42 and the right-angle frame 43 away from the side plate 21, so that when the side plate 21 rotates to a vertical position, the rotating plate 24 automatically opens. When the side plate 21 rotates to a horizontal position, the first electric push rod drives the right-angle frame 43 to move and squeeze the rotating plate 24. The rotating plate 24 covers the first drainage groove 23 of the side plate 21, sealing the first drainage groove 23. At the same time, as the right-angle frame 43 moves, the insertion tube 44 is inserted into the insertion hole 210, and hot air is blown into the side plate 21 by a hot air blower, flowing out from the inside of the porous moisture-absorbing plate 212 and out through the air outlet 22. This part of the technology is based on the regeneration principle of the porous moisture-absorbing plate 212, which belongs to the organic framework MOFs: novel porous The material has a large specific surface area, and some types can be rapidly regenerated at relatively low temperatures (<100℃). When the side plate 21 is vertical, the sealing strip 26 and the connecting frame 25 leave the second trough 27 via the return spring 211. At this time, air enters the enclosed space through the second trough 27, the porous moisture-absorbing plate 212, and the first trough 23, providing heat dissipation for the monitoring device 3 while protecting it from rain and moisture corrosion. When the side plate 21 rotates to a vertical position, the abutment 28 of the connecting frame 25 presses against the baffle 12, causing the connecting frame 25 and the sealing strip 26 to move and insert into the second trough 27, sealing the position of the second trough 27. At this time, as the insertion tube 44 is inserted into the side plate 21, the porous moisture-absorbing plate 212 inside is dried and regenerated by blowing air, while avoiding air... Air flows out from the first drain 23 and the second drain 27, and can only flow out from the air outlet 22, maintaining efficient and uniform airflow to the porous moisture-absorbing plate 212. The heat dissipation windows 33 and cooling fans on both sides of the monitoring device 3 provide air intake and exhaust respectively, thus working with the side plate 21 to maintain air circulation. When the side plate 21 is in a vertical state, it automatically unfolds and merges into a box-like structure. The top plate 31 prevents rainwater from flowing into the interior from the top, and the drainage groove 11 of the base 1 drains the rainwater accumulated on the base 1. The photovoltaic panels on the rotating plate 24 can power the equipment. Using existing photovoltaic power generation technology, when the side plate 21 is vertical, the photovoltaic panels of the rotating plate 24 face outwards to generate photovoltaic power. After the side plate 21 is rotated open...The side panel 21 is pressed by the right-angle frame 43, covering the photovoltaic panel 21. At this time, the photovoltaic panel is also facing upwards, and photovoltaic power generation can still be carried out. This is done simultaneously with the drying and regeneration of the porous moisture-absorbing plate 212 inside the side panel 21. Through the spatial positioning function of GIS, the specific location and working status of each rainfall monitoring station can be viewed intuitively, including the total number and zonal distribution of monitoring devices 3, the number and online status of IoT devices, the trend changes of key monitoring indicators, and the latest reported monitoring data. The temperature, humidity, pressure and wind meteorological sensors monitor and collect meteorological information near the stations in real time. Using a data-driven model based on deep learning, the coupling relationship between meteorological parameters and target rainfall events is learned and fitted by training a large amount of long-term meteorological parameter data, realizing short-term nearby rainfall prediction.
