[0002] Water conservancy projects play an important role in modern society and are widely used in fields such as water resource management, flood control and drainage, hydropower generation, irrigation, etc. With the continuous expansion of the scale of water conservancy projects and the increasing complexity of technologies, ensuring their safe and efficient operation has become particularly important. To achieve this goal, real-time monitoring of the operation status of water conservancy projects and timely discovery of potential safety hazards have become key links in the management of water conservancy projects.

[0003] However, traditional methods for monitoring the operation status of water conservancy projects mainly rely on manual inspections and physical detections of local equipment, such as water level gauges, flow meters, pressure sensors, etc. Although these methods can provide real-time monitoring data to a certain extent, they are restricted by the time and space limitations of manual inspections and cannot achieve continuous and real-time monitoring of a wide area, making it difficult to comprehensively and accurately reflect the overall operation status of water conservancy projects, thereby reducing the risk management ability of water conservancy projects.

[0044] Further, the emergency warning control of the operation facilities corresponding to the water conservancy project according to the operation risk score of the water conservancy project in step S45 includes comparing and judging the operation risk score of the water conservancy project according to a preset operation risk threshold. If the operation risk score of the water conservancy project is less than the preset operation risk threshold, the operation facilities corresponding to the water conservancy project will continue to be monitored; if the operation risk score of the water conservancy project is greater than or equal to the preset operation risk threshold, the operation facilities will automatically start the warning mechanism to send a warning signal to the water conservancy project management personnel, and respond to generate corresponding adjustments to the sluice opening, control the water level of the reservoir area, and reduce the displacement pressure corresponding to the dam body, so as to generate an emergency control plan for the operation state of the water conservancy project.

[0049] A water conservancy project emergency warning module, which is used to perform water conservancy operation risk monitoring on the operation facilities corresponding to the water conservancy project based on the seepage-induced displacement of the water conservancy dam body and the water conservancy sluice opening degree and in combination with the meteorological potential factors and topographic potential factors corresponding to the water area of the water conservancy project to obtain the operation risk score of the water conservancy project; perform emergency warning control on the operation facilities corresponding to the water conservancy project according to the operation risk score of the water conservancy project to generate an emergency control plan for the operation state of the water conservancy project.

[0050] The beneficial effects of the present invention:

[0051] 1. The method for monitoring the operation status of water conservancy projects proposed by the present invention, compared with the prior art, the beneficial effects of the present application are as follows: by real-time monitoring the stress and strain data of the water conservancy dam body, the seepage pressure data of the water conservancy dam body, the opening position data of the sluice, the water level data of the water area, and the water flow velocity data at key parts such as the dam body, sluice and water area, it is like installing countless pairs of sensitive "eyes" for the water conservancy project, capturing every subtle change in the process of project operation in real time. At the same time, obtaining the corresponding regional meteorological data and regional topographic and geomorphic data around the water conservancy project further broadens the monitoring vision. Meteorological factors such as precipitation and wind speed directly affect the water level and flow velocity of the water area, while the topographic and geomorphic features determine the flow direction, convergence and drainage path of the water flow, etc. Transmitting all these data to the central data processing center constructs a huge and comprehensive data resource library. This resource library not only provides a rich data basis for subsequent analysis work, but also can comprehensively consider the impact of various factors on the operation of the water conservancy project. It breaks the data island effect, so as to realize continuous and real-time monitoring of a wide area and can more comprehensively and accurately reflect the overall operation status of the water conservancy project. Secondly, through the dam body displacement analysis of the dam body based on the stress and strain data of the water conservancy dam body and the seepage pressure data of the water conservancy dam body, and by accurately calculating the seepage deformation displacement of the water conservancy dam body, the deformation of the dam body under the action of various complex factors can be understood in time. Once it is found that the displacement exceeds the normal range, targeted measures can be quickly taken, such as strengthening the dam body, adjusting the water storage strategy, etc. And based on the opening position data of the sluice, the sluice opening degree is statistically analyzed. The sluice is a key facility for controlling the water flow, and the accurate grasp of its opening degree directly affects the functions of flood control, irrigation, shipping, etc. of the water conservancy project. Accurate sluice opening degree data enables the manager to scientifically and reasonably allocate and efficiently utilize water resources according to actual needs, such as increasing the opening degree to quickly discharge flood during flood season flood control and precisely regulating to ensure irrigation water during dry season, improving the scientificity and stability of the operation of the water conservancy project. Then, by devoting to exploring the potential relationship between regional meteorological data and regional topographic and geomorphic data and water area water level data and water area flow velocity data. For example, heavy rainfall will quickly increase the water volume in the water area, resulting in rising water level and accelerating flow velocity, while continuous drought will cause the water level to drop. By deeply analyzing the regional meteorological data, the changing trend of water level and flow velocity caused by meteorological factors can be predicted in advance. The complex terrain forms special water flow channels, affecting the convergence and dispersion of water flow, and then changing the water level and flow velocity distribution. By exploring the potential factors of the terrain, the natural characteristics of the water area in different sections can be clearly understood, providing a scientific basis for the planning and operation of the water conservancy project. For example, in areas with low-lying terrain prone to waterlogging, optimize the drainage facilities in advance or formulate special water level control strategies. This kind of exploration and analysis of meteorological potential factors and terrain potential factors can enable the manager to plan ahead and respond in advance to the adverse effects that may be caused by meteorological and topographic factors on the water area of the water conservancy project, ensuring the safe and stable operation of the water conservancy project.Finally, by integrating the data obtained from the previous steps with the analysis results, comprehensive risk monitoring and emergency control are carried out on the operation facilities of the water conservancy project. This process is like building an all-round "risk radar" for the operation of the water conservancy project. The risk score calculated by comprehensively considering various key factors can accurately reflect the risk level of the water conservancy project in the current state. And based on the risk score of the water conservancy project operation, emergency warning control is carried out on the corresponding operation facilities of the water conservancy project, and an emergency control plan for the corresponding operation state of the water conservancy project is generated, which provides a strong guarantee for dealing with emergencies. When the risk score exceeds the safety threshold, the warning mechanism can be triggered in a timely manner to notify relevant personnel to take emergency measures. The emergency control plan is like a detailed "battle plan", which clarifies the specific actions to be taken at different risk levels, such as adjusting the sluice opening, controlling the water level of the reservoir area, and reducing the displacement pressure corresponding to the dam body. This series of operations can greatly improve the ability of the water conservancy project to cope with risks, minimize disaster losses to the greatest extent, and thus improve the risk management ability of the water conservancy project.

[0052] 2. The water conservancy project operation state monitoring system proposed by the present invention is generally composed of a water conservancy project data acquisition module, a dam body displacement and opening degree statistics module, a potential impact excavation module of the water area, and a water conservancy project emergency warning module. It can implement any water conservancy project operation state monitoring method described in the present invention, and is used to realize the water conservancy project operation state monitoring method through the operations between computer programs running on each module. The internal structure of the system cooperates with each other, which can greatly reduce repetitive work and manpower investment, and can quickly and effectively provide a more accurate and efficient water conservancy project operation state monitoring process, thus simplifying the operation process of the water conservancy project operation state monitoring system.

[0060] To achieve the above object, please refer to Figures 1 to 3 , the present invention provides a method for monitoring the operation status of a water conservancy project, and the method includes the following steps:

[0061] Step S1: Real-time monitor the corresponding stress and strain data of the water conservancy dam, seepage pressure data of the water conservancy dam, opening position data of the sluice, water level data of the water area, and water flow velocity data of the water area at the dam body, sluice and water area corresponding to the water conservancy project; obtain the corresponding regional meteorological data and regional topographic and geomorphic data around the water conservancy project, and transmit them together with the stress and strain data of the water conservancy dam, seepage pressure data of the water conservancy dam, opening position data of the sluice, water level data of the water area, and water flow velocity data to the central data processing center corresponding to the water conservancy project;

[0062] Step S2: Based on the stress and strain data of the water conservancy dam and the seepage pressure data in the central data processing center, perform dam displacement analysis on the dam body corresponding to the water conservancy project to obtain the seepage-induced displacement of the water conservancy dam; based on the opening position data of the sluice, perform sluice opening degree statistics on the sluice corresponding to the water conservancy project to obtain the opening degree of the water conservancy sluice;

[0063] Step S3: Based on the regional meteorological data and regional topographic and geomorphic data, conduct mining and analysis of the potential impacts of water level data and water flow velocity data in the water area to obtain the meteorological potential factors and topographic potential factors corresponding to the water area of the water conservancy project;

[0064] Step S4: Based on the seepage deformation displacement of the water conservancy dam and the opening degree of the water conservancy sluice, and combined with the meteorological potential factors and topographic potential factors corresponding to the water area of the water conservancy project, monitor the operation risks of the operation facilities corresponding to the water conservancy project to obtain the operation risk score of the water conservancy project; According to the operation risk score of the water conservancy project, conduct emergency warning control on the operation facilities corresponding to the water conservancy project to generate an emergency control plan for the operation status of the water conservancy project.

[0065] In the embodiment of the present invention, please refer to Figure 1 As shown, it is a schematic diagram of the step flow of the water conservancy project operation status monitoring method of the present invention. In this example, the water conservancy project operation status monitoring method includes the following steps:

[0066] Step S1: Real-time monitor the corresponding stress and strain data of the water conservancy dam, seepage pressure data of the water conservancy dam, water gate opening position data, water area water level data, and water area flow velocity data at the dam, sluice, and water area corresponding to the water conservancy project; Obtain the corresponding regional meteorological data and regional topographic and geomorphic data around the water conservancy project, and transmit them together with the stress and strain data of the water conservancy dam, seepage pressure data of the water conservancy dam, water gate opening position data, water area water level data, and water area flow velocity data to the central data processing center corresponding to the water conservancy project;

[0067] In an embodiment of the present invention, at the dam body corresponding to the water conservancy project, high-precision vibrating wire strain sensors and piezoresistive osmotic pressure sensors are installed. The strain sensors collect the stress and strain data of the dam body every 10 minutes, and convert the measured change in the vibrating wire frequency into stress and strain values. For example, at a certain moment, the stress value at a certain position of the dam body is measured to be 10 MPa. The osmotic pressure sensors collect the osmotic pressure data of the dam body every 15 minutes and output data by sensing the change in water pressure. For example, the osmotic pressure measured at a depth of 5 meters in the dam body is 0.5 MPa. At the sluice, an optoelectronic position sensor is used to collect the sluice opening position data every second, and the position is determined by detecting the reflective markings on the gate. If the current opening height of the sluice is 2.5 meters, then this data is recorded. In the water area, an ultrasonic water level sensor is used to measure the water level data of the water area every 30 seconds, and the water level is calculated by transmitting and receiving ultrasonic waves. For example, the current water level of the water area is 10.2 meters; a Doppler current meter is used to collect the water flow velocity data of the water area every second, and the water flow velocity is measured using the Doppler effect. For example, the current water flow velocity is 1.8 m / s. A meteorological monitoring station is set up around the water conservancy project, equipped with devices such as an anemometer, a rain gauge, a temperature sensor, and a barometric pressure sensor, and the regional meteorological data is collected every 10 minutes. For example, the wind speed is 3 m / s, the rainfall is 5 mm, the temperature is 25 °C, and the barometric pressure is 1200 Pa. The regional topographic and geomorphic data is obtained by combining satellite remote sensing technology and ground surveying. For example, the satellite remote sensing images are used to obtain information such as the mountain range trend and river distribution, and total stations, levels, etc. are used to measure the terrain slope, elevation, and other data on site. All the collected data is transmitted to the central data processing center corresponding to the water conservancy project through a 4G wireless communication module to ensure real-time and accurate data transmission.

[0068] Step S2: Based on the stress and strain data of the water conservancy dam body and the osmotic pressure data of the water conservancy dam body in the central data processing center, perform dam body displacement analysis on the dam body corresponding to the water conservancy project to obtain the osmotic displacement of the water conservancy dam body; based on the sluice opening position data, perform sluice opening degree statistics on the sluice corresponding to the water conservancy project to obtain the sluice opening degree of the water conservancy sluice;

[0069] In the embodiments of the present invention, at the central data processing center, by using the data analysis libraries of Python, such as NumPy and SciPy, combined with the professional finite element analysis software ANSYS, the dam displacement analysis is carried out on the stress and strain data of the hydraulic dam body and the seepage pressure data of the hydraulic dam body, so as to input the stress and strain data and the seepage pressure data into the physical structure mechanics model of the dam established in ANSYS, use the finite element algorithm to simulate the mechanical behavior of the dam under these loads and boundary conditions, and by analyzing the calculation results, extract the displacement information of the dam at different positions to obtain the seepage and deformation displacement of the hydraulic dam body. For example, after calculation, the displacement magnitude and direction of a certain point at the dam crest under the current working condition are obtained, including the displacement magnitude of 8 mm at the center of the dam crest and the direction to the left, the displacement magnitude of 5 mm at 1 / 4 of the left side of the dam body and the direction 15° downward and to the left, the displacement magnitude of 6 mm at 1 / 4 of the right side of the dam body and the direction 20° downward and to the right, and the displacement magnitude of 3 mm at the center of the dam bottom and the direction to the right. For the statistics of the water gate opening degree, the Pandas library of Python is used to process the water gate opening position data. Assuming that the initial closed position of the water gate is 0 m and the maximum opening position is 5 m, according to the current water gate opening position data, the water gate opening degree is obtained by calculating (current opening position - initial closed position) ÷ (maximum opening position - initial closed position) × 100%. For example, if the current water gate opening position is 3 m, the water gate opening degree is (3 - 0) ÷ (5 - 0) × 100% = 60%, and finally the water gate opening degree of the hydraulic water gate is obtained.

[0070] Step S3: Based on the regional meteorological data and the regional topographic and geomorphic data, conduct mining and analysis on the water area water level data and the water area flow velocity data to obtain the meteorological potential factors and the topographic potential factors corresponding to the water area of the hydraulic engineering;

[0071] In an embodiment of the present invention, by using the geographic information system (GIS) software ArcGIS and the relevant libraries of Python, the water level data and the water velocity data of the water area are mined and analyzed based on the regional meteorological data and the regional topographic data. In ArcGIS, the meteorological data and the topographic data are processed by spatial analysis tools. For example, the meteorological data points are interpolated by the "Kriging interpolation" tool to generate a continuous distribution layer of meteorological elements such as rainfall and temperature, and the spatial distribution law is analyzed. In combination with the principles of geomechanics and hydrology, the topographic data are processed by surface analysis tools such as "slope" and "slope direction" to obtain terrain elevation, slope, slope direction, etc. The data is collected and analyzed for its impact on the movement of water flow in the water area. The Python NetworkX library is used to build an association network, and meteorological elements (such as rainfall and wind speed), terrain elements (such as terrain slope and water system connectivity) and water area variables (such as water level and flow velocity) are used as nodes. According to physical principles and data analysis, the influence relationship between the elements is determined as an edge. By traversing the association network, the influence intensity of each node on the water level and flow velocity nodes in the water area is calculated, and the meteorological and terrain elements that have a significant impact on the water level and flow velocity of the water area are screened out. The meteorological potential factors (such as precipitation intensity and wind speed) and terrain potential factors (such as terrain slope and terrain water system connectivity) corresponding to the water area of ​​the water conservancy project are obtained.

[0072] Step S4: Based on the seepage displacement of the water conservancy dam body and the opening of the water conservancy sluice, and in combination with the meteorological potential factors and terrain potential factors corresponding to the water area of ​​the water conservancy project, the water conservancy operation risk of the operating facilities corresponding to the water conservancy project is monitored to obtain the water conservancy project operation risk score; according to the water conservancy project operation risk score, emergency early warning control is performed on the operating facilities corresponding to the water conservancy project to generate an emergency control plan for the operation status corresponding to the water conservancy project.

[0073] In the embodiment of the present invention, in the central data processing center, a program is written in Python to quantitatively calculate the seepage displacement of the hydraulic dam obtained from previous analysis over a period of time, collect data once every 10 minutes, and send the data to the data collector in the monitoring center by means of wired transmission. In the monitoring center, data processing software is used to analyze the seepage displacement of the hydraulic dam collected. By calculating the ratio of the difference between two adjacent collected data to the time interval, the seepage displacement rate of the dam is obtained. At the same time, the displacement data collected each time is accumulated to obtain the cumulative displacement of the dam. And by installing a water level sensor and a flow velocity meter respectively upstream and downstream of the water area of the water conservancy project, the water level sensor uses a pressure type water level gauge to measure the water level data once every 15 minutes; the flow velocity meter uses a Doppler flow velocity meter to measure the water flow velocity data once every 20 minutes. These devices transmit the data to the server in the monitoring center in real time through a wireless communication module. By querying the water level data of the upstream and downstream at the same moment in the database, the difference between the two is calculated to obtain the upstream and downstream water level difference. For the water flow velocity data, the average value of the measured values within a certain period of time (such as 1 hour) is taken as the water flow velocity in this period. At the same time, a special opening degree matching degree calculation program is run. This program analyzes the relationship between the opening degree of the water conservancy sluice, the upstream and downstream water level difference, and the water flow velocity based on the mathematical model established according to the hydraulic principle and historical data. The program first divides multiple intervals according to different value ranges of the sluice opening degree. For each interval, combined with the historical data of the upstream and downstream water level difference and the water flow velocity, the theoretically optimal matching value is determined. Then, the current upstream and downstream water level difference and the water flow velocity are substituted into the model to calculate the actual matching value. By comparing the actual matching value with the theoretical optimal matching value, the matching degree between the sluice opening degree and the upstream and downstream water level difference and the water flow velocity is finally obtained. By presetting the hydraulic influence weights of the seepage displacement rate of the dam, the cumulative displacement of the dam, and the matching degree between the sluice opening degree and the upstream and downstream water level difference and the water flow velocity on the server, which are 0.3, 0.2, and 0.5 respectively. At the same time, combined with the meteorological potential factors and topographic potential factors corresponding to the water area of the water conservancy project, the meteorological potential factors are obtained in real time through a meteorological station, including information such as precipitation intensity and wind speed; the topographic potential factors are determined according to the previous geological exploration data, such as the terrain slope and the terrain water system connectivity, etc. The meteorological potential factors and topographic potential factors are converted into quantified scores, and the weighted summation method is used for the quantitative calculation of the water conservancy operation risk, that is, the water conservancy project operation risk score = seepage displacement rate of the dam × 0.3 + cumulative displacement of the dam × 0.2 + matching degree × 0.5 + meteorological potential factor score + topographic potential factor score, so as to obtain the water conservancy project operation risk score.Finally, according to the preset operation risk threshold of 80 points, compare the calculated risk score with the threshold. If the risk score is less than 80 points, continue to monitor the data in real time; if the risk score is greater than or equal to 80 points, automatically activate the emergency warning mechanism, send a warning signal to the water conservancy project management personnel through the SMS platform, and at the same time call the pre-written emergency plan generation program to generate measures such as adjusting the sluice opening and controlling the water level of the reservoir according to the specific situation of the risk, and form an emergency control plan for the operation state of the water conservancy project.

[0074] Further, step S1 includes the following steps:

[0075] Step S11: Install corresponding strain sensors and piezometric sensors at the dam body corresponding to the water conservancy project, install corresponding position sensors at the sluice corresponding to the water conservancy project, and at the same time install corresponding water level sensors and flow velocity sensors at the water area corresponding to the water conservancy project;

[0076] Step S12: Use the strain sensors and piezometric sensors at the dam body corresponding to the water conservancy project to monitor the stress and strain data of the water conservancy dam body and the piezometric data of the water conservancy dam body in real time, use the position sensors at the sluice corresponding to the water conservancy project to monitor the sluice opening position data in real time, and at the same time use the water level sensors and flow velocity sensors at the water area corresponding to the water conservancy project to monitor the water area water level data and water area flow velocity data in real time;

[0077] Step S13: Obtain the corresponding regional meteorological data around the water conservancy project;

[0078] Step S14: Obtain the corresponding regional topographic and geomorphic data around the water conservancy project;

[0079] Step S15: Transmit the corresponding regional meteorological data and regional topographic and geomorphic data around the water conservancy project, as well as the stress and strain data of the water conservancy dam body, the piezometric data of the water conservancy dam body, the sluice opening position data, the water area water level data and the water area flow velocity data to the central data processing center corresponding to the water conservancy project through wireless communication technology.

[0080] As an embodiment of the present invention, refer to Figure 2 shown, for Figure 1 the detailed step flow schematic diagram of step S1 in

[0081] Step S11: Install corresponding strain sensors and piezometric sensors at the dam body corresponding to the water conservancy project, install corresponding position sensors at the sluice corresponding to the water conservancy project, and at the same time install corresponding water level sensors and flow velocity sensors at the water area corresponding to the water conservancy project;

[0082] In the embodiment of the present invention, at the dam corresponding to the water conservancy project, high-precision vibrating wire strain sensors and piezoresistive osmotic pressure sensors are selected. At the key stress-bearing parts inside the dam, such as the connection between the dam foundation and the dam body, the water-facing side of the dam, etc., one strain sensor is installed every 10 meters, and a total of 50 are installed. Through drilling, the osmotic pressure sensors are buried at different depths inside the dam, namely at 5 meters, 10 meters, and 15 meters, with 3 installed at each depth. At the sluice corresponding to the water conservancy project, optoelectronic position sensors are used and installed beside the lifting track of the sluice gate. By detecting the reflective marks on the sluice gate, the opening position of the sluice is determined, and a total of 2 are installed to ensure that the position change of the sluice gate can be accurately monitored. At the water area corresponding to the water conservancy project, ultrasonic water level sensors and Doppler flow velocity sensors are selected. 3 water level sensors are installed at the upstream and downstream of the water area, with an interval of 50 meters. The water level is measured by transmitting and receiving ultrasonic waves. 4 Doppler flow velocity sensors are installed at positions where the water flow is relatively turbulent and representative, and the flow velocity of the water flow is measured using the Doppler effect.

[0083] Step S12: At the dam corresponding to the water conservancy project, use strain sensors and osmotic pressure sensors to continuously monitor the stress-strain data and osmotic pressure data of the corresponding water conservancy dam in real time, and at the sluice corresponding to the water conservancy project, use position sensors to continuously monitor the opening position data of the corresponding sluice in real time. At the same time, at the water area corresponding to the water conservancy project, use water level sensors and flow velocity sensors to continuously monitor the water level data and water area flow velocity data of the corresponding water area in real time;

[0084] In the embodiment of the present invention, at the dam, the strain sensors and osmotic pressure sensors collect data at a frequency of 1 time per second. The strain sensors measure the frequency change of their own vibrating wires and convert it into the stress-strain data of the dam. For example, when the dam is stressed and undergoes a small deformation, the vibrating wire frequency of the strain sensor changes from 1000 Hz to 1005 Hz, and the stress-strain value of the dam is obtained through conversion. The osmotic pressure sensors convert the induced water pressure change into the osmotic pressure data of the dam. For example, at a depth of 10 meters, the osmotic pressure sensor detects that the water pressure is 1.2 MPa, which is recorded as the osmotic pressure data of the dam. At the sluice, the position sensors monitor the opening position data of the sluice at a frequency of 2 times per second, and determine the opening height of the sluice by detecting the position change of the reflective marks. For example, the current opening height of the sluice is 2 meters. At the water area, the water level sensors collect the water area water level data every 10 seconds, and calculate the water level through the ultrasonic reflection time. For example, the current upstream water level is 50.2 meters. The flow velocity sensors collect the water area flow velocity data at a frequency of 5 times per second, and calculate the water flow velocity according to the Doppler frequency shift. For example, the current water flow velocity is 2.5 m / s.

[0085] Step S13: Obtain the corresponding regional meteorological data around the water conservancy project;

[0086] In an embodiment of the present invention, by setting up a meteorological monitoring station around the water conservancy project, and equipping it with devices such as an anemometer, a rain gauge, a temperature sensor, and a barometric pressure sensor. The anemometer is a three-cup anemometer, which calculates the wind speed by measuring the rotation speed of the wind cups, and records the wind speed data every 5 minutes. For example, the current wind speed is 3.5 m / s. The rain gauge is a tipping bucket rain gauge, which measures the rainfall by counting the number of times the tipping bucket flips, and records the rainfall data every 10 minutes. For example, the rainfall in the past 10 minutes is 2 mm. The temperature and barometric pressure sensors record the temperature and barometric pressure data every 15 minutes. For example, the current temperature is 25 °C and the barometric pressure is 1200 Pa. These meteorological data are summarized to form the corresponding regional meteorological data around the water conservancy project.

[0087] Step S14: Obtain the corresponding regional topographic and geomorphic data around the water conservancy project;

[0088] In an embodiment of the present invention, the corresponding regional topographic and geomorphic data around the water conservancy project are obtained by combining satellite remote sensing technology and ground surveying and mapping. Through satellite remote sensing images, large-area topographic and geomorphic information such as mountain ranges and river distributions are obtained. An unmanned aerial vehicle (UAV) equipped with a high-definition camera is used to take low-altitude photos of key areas around the water conservancy project to obtain more detailed topographic and geomorphic data. At the same time, total stations, levels and other ground surveying and mapping instruments are used to conduct on-site measurements of key topographic and geomorphic feature points, such as measuring data such as the terrain slope and elevation around the dam body. The satellite remote sensing data, UAV photo data, and ground surveying and mapping data are integrated and processed to generate a digital elevation model (DEM) and a digital orthophoto map (DOM) of the area around the water conservancy project, forming comprehensive regional topographic and geomorphic data.

[0089] Step S15: Transmit the corresponding regional meteorological data and regional topographic and geomorphic data around the water conservancy project, as well as the stress and strain data of the water conservancy dam body, the seepage pressure data of the water conservancy dam body, the opening position data of the sluice, the water level data of the water area, and the water flow velocity data of the water area to the central data processing center corresponding to the water conservancy project through wireless communication technology.

[0090] In the embodiments of the present invention, by installing wireless communication modules at each data collection point (dam body, sluice, water area, meteorological monitoring station) and the central data processing center, and adopting 4G communication technology for data transmission. At the dam body, the data of strain sensors and seepage pressure sensors are packed through the wireless communication module. Each data packet contains information such as sensor number, collection time, data value, etc. The data packet is sent to the central data processing center every 1 minute. At the sluice, the data of position sensors are also packed and sent once every 30 seconds. At the water area, after integrating the data of water level sensors and flow velocity sensors, it is sent once every 2 minutes. The meteorological monitoring station organizes the collected regional meteorological data into data packets and sends them once every 5 minutes. After receiving the data packets, the central data processing center classifies and stores different types of data into corresponding database tables through a data parsing program. For example, the dam body stress and strain data are stored in the "dam body data" table, and the water area water level data are stored in the "water area data" table, which is convenient for subsequent analysis and processing.

[0091] Further, the regional meteorological data described in step S13 includes rainfall, temperature, air pressure, and wind speed corresponding to the area around the water conservancy project.

[0092] Further, step S2 includes the following steps:

[0093] Step S21: Synchronize the time series of the stress and strain data of the water conservancy dam body and the seepage pressure data of the water conservancy dam body in the central data processing center to obtain the corresponding dam body stress and strain data and dam body seepage pressure data at the same time series;

[0094] Step S22: Obtain the elastic modulus, Poisson's ratio, geometric shape, and boundary conditions of the dam body corresponding to the water conservancy project through the dam body of the water conservancy project, and perform a dam body physical structure modeling on the dam body corresponding to the water conservancy project based on the elastic modulus, Poisson's ratio, geometric shape, and boundary conditions of the dam body corresponding to the water conservancy project to generate a dam body physical structure mechanics model corresponding to the water conservancy project;

[0095] Step S23: Perform a dam body displacement analysis on the dam body physical structure mechanics model corresponding to the water conservancy project based on the corresponding dam body stress and strain data and dam body seepage pressure data at the same time series to obtain the seepage displacement of the water conservancy dam body;

[0096] Step S24: Statistically calculate the opening degree of the sluice corresponding to the water conservancy project based on the sluice opening position data to obtain the opening degree of the water conservancy sluice.

[0097] As an embodiment of the present invention, refer to Figure 3 shown, for Figure 1 the detailed step flow schematic diagram of step S2 in

[0098] Step S21: Align the stress-strain data and seepage pressure data of the hydraulic dam in time series within the central data processing center to obtain the corresponding dam stress-strain data and dam seepage pressure data at the same time series;

[0099] In the embodiment of the present invention, within the central data processing center, the Pandas library of Python is used to perform time series synchronization alignment on the stress-strain data and seepage pressure data of the hydraulic dam. Assume that the stress-strain data of the dam is stored in a Pandas DataFrame data structure stress_strain_df, which contains a timestamp column timestamp and a stress-strain data column stress_strain_values; the seepage pressure data of the dam is stored in seepage_pressure_df, which contains a timestamp column timestamp and a seepage pressure data column seepage_pressure_values. First, check whether the timestamp formats in the two DataFrames are consistent. If not, convert the timestamps to a unified datetime format using the pd.to_datetime() function. Then, use the pd.merge() function to perform an inner join operation based on the timestamp column to merge the two DataFrames into a new DataFrame merged_df. For example, merged_df = pd.merge(stress_strain_df, seepage_pressure_df, on='timestamp', how='inner'). In this way, in merged_df, each row of data corresponds to the dam stress-strain data and dam seepage pressure data at the same time series, providing a time-synchronized data basis for subsequent analysis.

[0100] Step S22: Obtain the elastic modulus, Poisson's ratio, geometric shape, and boundary conditions of the dam corresponding to the hydraulic project through the dam corresponding to the hydraulic project, and perform dam physical structure modeling on the dam corresponding to the hydraulic project based on the elastic modulus, Poisson's ratio, geometric shape, and boundary conditions of the dam corresponding to the hydraulic project to generate a dam physical structure mechanical model corresponding to the hydraulic project;

[0101] In an embodiment of the present invention, a physical structure model of the dam corresponding to a water conservancy project is established by using a professional finite element analysis software ANSYS. Parameters such as the elastic modulus, Poisson's ratio, geometric shape, and boundary conditions of the dam are obtained from engineering design documents and geological exploration reports. The elastic modulus is determined through laboratory tests on dam building materials (such as concrete, earth and rock, etc.). Assuming the elastic modulus of a concrete dam is 30 GPa, Poisson's ratio is also obtained through material tests, for example, it is 0.2. The geometric shape is determined through on-site measurement and design drawings. The shape of the dam is constructed in the ANSYS software in the form of a three-dimensional model, including parameters such as the height, width, and slope of the dam. The boundary conditions are determined according to factors such as the contact between the dam and the foundation, surrounding soil, and water pressure. For example, the dam foundation is fixed and constrained, and the upstream face of the dam bears hydrostatic pressure. In the ANSYS software, the material properties, geometric shape, and boundary conditions of the model are set according to the obtained parameters. After preprocessing steps such as mesh generation, a physical structure mechanical model of the dam corresponding to the water conservancy project is generated. This model can simulate the mechanical response of the dam under various working conditions.

[0102] Step S23: Based on the stress-strain data and seepage pressure data of the dam corresponding at the same time sequence, perform dam displacement analysis on the physical structure mechanical model of the dam corresponding to the water conservancy project to obtain the seepage-induced displacement of the water conservancy dam.

[0103] In an embodiment of the present invention, by inputting the previously obtained stress-strain data and seepage pressure data of the dam corresponding at the same time sequence into the previously established physical structure mechanical model of the dam, in the ANSYS software, using its built-in analysis module, the stress-strain data is used as the input load of the model, and the seepage pressure data is used as the pore water pressure boundary condition. Through finite element calculation, the mechanical behavior of the dam under the action of these loads and boundary conditions is simulated. For example, the stress distribution inside the dam is calculated according to the stress-strain data, and the influence of pore water pressure on the dam stability is considered in combination with the seepage pressure data. By analyzing the calculation results, the displacement information of the dam at different positions is extracted, so as to obtain the seepage-induced displacement of the water conservancy dam. For example, by viewing the displacement of a certain point on the dam crest at a specific moment through the post-processing module, the displacement is 5 mm and the direction is downward. These displacement data are sorted into a table form, recording the magnitude, direction, corresponding time, and position information of the displacement.

[0104] Step S24: Based on the water gate opening position data, perform water gate opening degree statistics on the water gate corresponding to the water conservancy project to obtain the water gate opening degree of the water conservancy project.

[0105] In an embodiment of the present invention, in the central data processing center, the data analysis function of Python is used to process the data of the water gate opening position to count the opening degree of the water conservancy water gate. It is assumed that the data of the water gate opening position is stored in a DataFrame data structure gate_position_df of Pandas, which includes a timestamp column timestamp and a water gate opening position data column gate_position_values. First, the initial closed position and the maximum opening position of the water gate are determined. For example, the initial closed position is 0 meters and the maximum opening position is 5 meters. For the water gate opening position data at each time point, the water gate opening percentage is obtained by calculating (current opening position - initial closed position) ÷ (maximum opening position - initial closed position) × 100%. For example, at a certain time point, the water gate opening position is 2 meters, then the water gate opening degree is (2 - 0) ÷ (5 - 0) × 100% = 40%. The calculation results of the water gate opening degrees at all time points are organized into a new DataFrame, which includes timestamps and the corresponding water gate opening degree data, facilitating subsequent analysis of the change trend of the water gate opening degree and correlation research with other data.

[0106] Further, step S23 includes the following steps:

[0107] Step S231: Using the finite element analysis method, divide the physical structure mechanical model of the dam corresponding to the water conservancy project into each tiny unit to generate the tiny units of the dam model corresponding to each water conservancy project;

[0108] In an embodiment of the present invention, in the ANSYS software, use its built-in mesh generation function to divide the physical structure mechanical model of the dam corresponding to the water conservancy project into tiny units. Select a suitable mesh generation algorithm, such as the tetrahedral mesh generation algorithm for complex geometric shapes. According to the size and analysis accuracy requirements of the dam model, set the element size. For example, for a small earth-rock dam model with a length of 100 meters and a height of 30 meters, to ensure the analysis accuracy, set the element size to 0.5 meters. Through software operation, specify the overall dam model and start the mesh generation program. The software will automatically divide the dam model into numerous tiny units to generate the tiny units of the dam model corresponding to each water conservancy project. After the division is completed, the software will generate a mesh information file, recording information such as the number, position, shape of each tiny unit, and the connection relationship with adjacent units, facilitating subsequent operations and analysis on the units.

[0109] Step S232: Based on the corresponding dam body stress and strain data and dam body seepage pressure data at the same time sequence, conduct dam body structure characteristic analysis on the micro-units of the dam body model corresponding to each water conservancy project, so as to calculate the corresponding stress and strain distribution in each micro-unit by combining the dam body stress and strain data, determine the weak parts and stress concentration areas corresponding to the dam body, and combine the dam body seepage pressure data to analyze the corresponding flow path and pressure distribution of seepage in each micro-unit, and obtain a set of dam body structure characteristic parameters reflecting the dam body stress and seepage pressure;

[0110] In the embodiment of the present invention, by using the analysis module of ANSYS software, load the corresponding dam body stress and strain data and dam body seepage pressure data at the same time sequence onto each micro-unit of the dam body model. For stress and strain analysis, distribute the stress and strain data to the corresponding micro-units according to the unit position. For example, if a certain micro-unit is located at the bottom of the dam body near the water-facing side, according to the corresponding value of this position in the overall dam body stress and strain data, apply the stress value as a load to this unit. Through the finite element algorithm, calculate the stress and strain distribution in each micro-unit. By analyzing the stress and strain distribution nephogram, the area with darker color is the stress concentration area, and the area where the unit deformation is large and exceeds the normal range is determined as the weak part of the dam body. For seepage pressure analysis, apply the seepage pressure data as the pore water pressure boundary condition to the micro-units. The software simulates the flow path of seepage in each micro-unit by solving the seepage control equation, calculates the pressure distribution, and organizes information such as stress and strain distribution, weak parts, stress concentration areas, seepage paths and pressure distribution into a data set, that is, obtain a set of dam body structure characteristic parameters reflecting the dam body stress and seepage pressure.

[0111] Step S233: Obtain the temperature change, uneven settlement, surrounding seismic activities and surrounding water flow impact corresponding to the dam body;

[0112] In the embodiments of the present invention, temperature changes, uneven settlement, surrounding seismic activities, and surrounding water flow impact information corresponding to the dam body are obtained through various monitoring devices arranged around the water conservancy project. A plurality of temperature sensors are arranged inside and on the surface of the dam body, and temperature data is collected every 15 minutes. By analyzing the differences in the data of temperature sensors at different positions, the temperature change situation of the dam body is obtained. For example, the surface temperature of the dam body can reach 35°C in summer, while the internal temperature is 28°C, and the temperature gradient is obvious. The elevation changes of different positions of the dam body are regularly measured using a level and a total station to monitor uneven settlement. For example, the dam body is measured once a month. If it is found that a certain corner point of the dam body has sunk by 5 cm within half a year, it is recorded as uneven settlement data. A seismic monitoring station is set up in the surrounding area, and seismic activities are monitored in real time through seismic sensors, including information such as the magnitude of the earthquake, the depth of the earthquake source, and the distance from the dam body. For example, a magnitude 3.0 earthquake occurred in the surrounding area, the depth of the earthquake source was 10 km, and the distance from the dam body was 5 km. The surrounding water flow impact is monitored by a flow meter and a pressure sensor installed in the waters around the dam body to obtain data such as the water flow velocity and the magnitude of the impact force. For example, the water flow velocity is 3 m / s, and the impact force on the dam body is 100 kN.

[0113] Step S234: Based on the dam body structure characteristic parameter set reflecting the stress and seepage pressure of the dam body and in combination with the temperature change, uneven settlement, surrounding seismic activities, and surrounding water flow impact corresponding to the dam body, perform dam body displacement correlation analysis on the dam body physical structure mechanical model of the water conservancy project to quantitatively evaluate the influence weights and interaction relationships between various factors on the dam body displacement, including stress and strain, seepage pressure, temperature, settlement, seismic activities, and water flow impact factors, so as to generate a dam body displacement correlation factor influence matrix;

[0114] In the embodiment of the present invention, in the ANSYS software, by using the parametric analysis function, based on the set of dam structure characteristic parameters corresponding to the dam stress and seepage pressure, and combining the temperature change, uneven settlement, surrounding seismic activity, and surrounding water flow impact data previously obtained for the dam, a dam displacement correlation analysis is carried out on the physical structure mechanical model of the dam corresponding to the water conservancy project. First, each factor is quantified. For example, the temperature change is converted into a temperature load and applied to the model, and the uneven settlement is converted into a nodal displacement boundary condition. Through multiple simulation calculations, by changing the value of one factor each time, the change of the dam displacement is observed, so as to quantitatively evaluate the influence weight of each factor on the dam displacement. For example, when the temperature load is increased by 10°C alone, the dam crest displacement increases by 2 mm, and when the water flow impact force is increased by 50 kN alone, the dam crest displacement increases by 3 mm. It can be seen that the influence weight of the water flow impact factor on the dam displacement is relatively large. At the same time, the change law of the dam displacement when different factors change simultaneously is analyzed to determine the interaction relationship between the factors. These influence weights and interaction relationships are sorted into a two-dimensional matrix to generate a dam displacement correlation factor influence matrix. The rows and columns of the matrix correspond to each factor respectively, and the matrix elements represent the influence weight and interaction strength between the factors.

[0115] Step S235: Based on the influence weights and interaction relationships corresponding to each factor in the dam displacement correlation factor influence matrix and in combination with the principles of structural mechanics, a dam displacement coupling calculation is carried out on the physical structure mechanical model of the dam corresponding to the water conservancy project to obtain the seepage-induced displacement of the water conservancy dam.

[0116] In the embodiment of the present invention, by relying on the influence weights and interaction relationships corresponding to each factor in the dam displacement correlation factor influence matrix, in the ANSYS software, a dam displacement coupling calculation is carried out on the physical structure mechanical model of the dam corresponding to the water conservancy project. In the solution settings of the software, the parameters in the influence matrix are used as inputs, and a suitable coupling analysis method is selected. For example, the sequential coupling method is adopted. First, the influence of stress-strain and seepage pressure on the dam displacement is calculated, and then the influence of factors such as temperature, uneven settlement, surrounding seismic activity, and surrounding water flow impact is considered in turn. Through iterative calculations, the displacement of the dam under the combined action of multiple factors is gradually solved. For example, after 10 iterative calculations, the displacement of a key position of the dam under the current working condition is finally obtained as 8 mm, and the direction is to the left. The displacement calculation results of different positions of the dam are summarized and sorted into a table containing displacement magnitude, direction, and corresponding position information to obtain the seepage-induced displacement data of the water conservancy dam, providing a key basis for evaluating the operation state of the dam of the water conservancy project.

[0117] Further, step S24 includes the following steps:

[0118] Step S241: Establish an opening position coordinate system for the sluice corresponding to the water conservancy project based on the sluice opening position data, so as to generate the corresponding sluice opening position coordinate system of the water conservancy project;

[0119] In the embodiment of the present invention, by taking the bottom center position of the sluice as the coordinate origin (0, 0), the x-axis is established along the width direction of the sluice, and the rightward direction is specified as the positive direction; the y-axis is established along the height direction of the sluice, and the upward direction is specified as the positive direction, so as to construct the sluice opening position coordinate system of the water conservancy project. The total station is used for coordinate measurement. Measurement control points are set at key positions such as the two side edges and the bottom of the sluice. The coordinate values of these control points in this coordinate system are measured by the total station, so as to determine the specific position of the coordinate system in the actual sluice structure. For example, a control point A is set at a position 1 meter away from the bottom on the left side edge of the sluice, and the total station measures its coordinate as (-5, 1). These measurement data are recorded to form the complete sluice opening position coordinate system information of the water conservancy project, which is used for the subsequent accurate description and analysis of the sluice opening position.

[0120] Step S242: Obtain the corresponding gate types through the sluice corresponding to the water conservancy project, including plane gates and radial gates;

[0121] In the embodiment of the present invention, by consulting the design drawings of the water conservancy project, the gate type information corresponding to the sluice is obtained. The design drawings clearly mark whether the sluice uses a plane gate or a radial gate. If the design drawings are missing, it can be determined by observing the sluice structure on the spot. For example, for a small irrigation sluice, it is observed that its gate is rectangular and flat, and it is lifted and lowered by a winch and a screw device. Thus, it can be judged that this sluice is a plane gate. For the sluices of some large water conservancy projects, if it is observed that the gate is circular arc-shaped and rotates around a fixed hinge axis to open and close, it can be determined as a radial gate. Accurately determining the gate type is the key prerequisite for subsequent targeted parameter analysis and opening calculation.

[0122] Step S243: Analyze the gate opening parameters for the corresponding sluice opening position coordinate system of the water conservancy project based on the gate type. For the plane gate, obtain the corresponding screw rotation position through the sluice opening position coordinate system of the water conservancy project, and calculate the opening height of the corresponding opening process of the plane gate based on the screw rotation position to obtain the corresponding gate opening height. For the radial gate, calculate the corresponding gate opening radian through the measurement of the corresponding opening position in the sluice opening position coordinate system of the water conservancy project, and calculate the water passing area of the corresponding opening process of the radial gate based on the gate opening radian to obtain the size of the corresponding gate opening water passing area, so as to obtain the gate opening parameters of the water conservancy project;

[0123] In the embodiment of the present invention, for a flat gate, a rotary encoder installed on the screw drive device is used to obtain the screw rotation position information. The rotary encoder is directly connected to the screw and can accurately measure the rotation angle of the screw. For example, the rotary encoder generates 1000 pulse signals per full rotation. When the screw rotates a certain angle, the rotary encoder outputs a corresponding number of pulses. By counting the number of pulses, the rotation angle of the screw can be calculated, and then the lifting height of the flat gate can be determined. Suppose the rotary encoder outputs 500 pulses. Since every 1000 pulses correspond to one full rotation of the screw, that is, lifting the flat gate by one unit height, the opening height of the flat gate at this time is 0.5 unit height. For a radial gate, by arranging multiple laser rangefinders in the coordinate system of the gate opening position, the distances between different positions of the radial gate and a fixed reference point during the opening process are measured. Based on these distance data and combined with trigonometric relationships, the opening radian of the gate is calculated. For example, given that the radius of the radial gate is 5 meters, and through measurement by the laser rangefinder, the distance between the gate edge and the fixed reference point at a certain opening moment is 6 meters. The cosine theorem can be used to calculate the corresponding central angle, and then the opening radian is obtained. According to the opening radian and the radius of the radial gate, the cross-sectional area of the water flow after the gate is opened is calculated using the sector area formula. For example, if the opening radian is 0.5 radians and the radius is 5 meters, according to the formula S = 0.5×r 2 ×θ (where r is the radius and θ is the radian), the cross-sectional area of the water flow is 6.25 square meters, thereby obtaining the opening parameters of the water conservancy project gate.

[0124] Step S244: Obtain the corresponding gate opening flow velocity, the water level difference between the upstream and downstream of the gate, and the flow turbulence correction coefficient during the opening process through the water gate corresponding to the water conservancy project, and perform statistical calculation of the gate opening degree for the water gate corresponding to the water conservancy project based on the corresponding gate opening flow velocity, the water level difference between the upstream and downstream of the gate, and the flow turbulence correction coefficient in combination with the gate opening parameters of the water conservancy project to obtain the water conservancy gate opening degree.

[0125] In an embodiment of the present invention, ultrasonic level gauges are installed upstream and downstream of the sluice to measure the water level difference between the upstream and downstream of the sluice. The ultrasonic level gauge measures the water level by emitting and receiving ultrasonic waves. Subtracting the water level values measured by the two ultrasonic level gauges upstream and downstream can obtain the water level difference between the upstream and downstream of the sluice. For example, if the upstream water level is 10.5 meters and the downstream water level is 8.3 meters, the water level difference is 2.2 meters. An electromagnetic flowmeter is installed in the flow passage of the sluice to measure the opening flow rate of the sluice. The electromagnetic flowmeter measures the water flow velocity using the principle of electromagnetic induction. If the measured opening flow rate of the sluice is 2.5 m / s, the water flow turbulence correction coefficient is determined according to the type of the sluice, the water flow conditions, and relevant empirical formulas. Assuming that through calculation and empirical value selection, the water flow turbulence correction coefficient of this sluice is 1.2. For a flat gate, according to the opening height of the gate and the width of the sluice, calculate the water passing area of the gate opening, and then combined with the opening flow rate of the sluice, the water level difference between the upstream and downstream, and the water flow turbulence correction coefficient, use the flow calculation formula in hydraulics to inversely deduce the sluice opening. For an arc gate, directly use the previously calculated water passing area, and also combined with the above parameters, use the flow calculation formula to inversely deduce the sluice opening. Assuming that after calculation, for a certain flat gate sluice, the final obtained hydraulic sluice opening is 30%, which provides key data on the operation of the sluice for the monitoring of the operation status of the hydraulic project.

[0126] Further, step S3 includes the following steps:

[0127] Step S31: Perform spatial registration on the regional meteorological data and the regional topographic and geomorphic data to obtain a corresponding regional multi-source dataset in the same geographic coordinate system;

[0128] In an embodiment of the present invention, by using geographic information system (GIS) software, such as ArcGIS, perform spatial registration on the regional meteorological data and the regional topographic and geomorphic data. For the regional meteorological data, assume that it is stored in a CSV file containing longitude and latitude, time, and meteorological element values (such as rainfall, temperature, etc.). First, create a new geodatabase in ArcGIS, import the CSV file as a table, and use the "Add XY Data" tool in ArcGIS to convert the meteorological data into a point feature class according to the longitude and latitude information in the CSV file, and set the correct coordinate system, such as the WGS1984 geographic coordinate system. For the regional topographic and geomorphic data, if it is in the digital elevation model (DEM) format, directly load the DEM data in ArcGIS to ensure that its coordinate system is consistent with the meteorological data. If not, perform coordinate system conversion through the "Projection and Transformation" tool to make the two in the same geographic coordinate system, thereby obtaining a corresponding regional multi-source dataset in the same geographic coordinate system. For example, convert the meteorological data points and DEM data of a certain region into the WGS1984 geographic coordinate system for convenient subsequent analysis.

[0129] Step S32: Meteorological and topographic characteristics are analyzed for the corresponding regional multi-source data sets in the same geographic coordinate system by combining physical process simulation to analyze the distribution patterns of rainfall, temperature, air pressure and wind speed, and the changing trends of terrain elevation, slope and slope direction on water flow movement, soil erosion and groundwater recharge in the water conservancy project area are analyzed by combining geomechanics and hydrological principles to obtain physical characteristics analysis results reflecting the inherent laws of meteorology and topography;

[0130] In an embodiment of the present invention, by using ArcGIS spatial analysis tools and professional meteorological analysis software, such as the WRF (Weather Research and Forecasting) model, the meteorological and terrain characteristics of the corresponding regional multi-source data sets in the same geographic coordinate system are analyzed. In ArcGIS, the "Kriging interpolation" tool is used to interpolate meteorological data points to generate continuous meteorological element distribution layers, such as the distribution layers of rainfall, temperature, air pressure and wind speed, and analyze their spatial distribution patterns. For example, through interpolation, it is found that the rainfall in a certain area shows a decreasing trend from southeast to northwest. In combination with the WRF model, the terrain data and initial meteorological conditions of the input area are used to simulate the evolution process of meteorological elements, and further verify and refine the distribution pattern. For the analysis of terrain characteristics, ArcGIS "surface analysis" tools, such as "slope" and "aspect" tools, are used to process DEM data to obtain terrain elevation, slope, and aspect data. Based on the principles of geomechanics and hydrology, the effects of these terrain elements on water flow movement, soil erosion, and groundwater recharge in the water conservancy project area are analyzed. For example, through calculations, it is found that in areas with large slopes and slopes toward rivers, water flow speeds up and the risk of soil erosion increases, while in low-lying areas, groundwater recharge is more obvious, and the analysis results of physical characteristics that reflect the inherent laws of meteorology and terrain are obtained.

[0131] Step S33: Based on the physical property analysis results reflecting the inherent laws of meteorology and topography, a correlation network is constructed between the corresponding regional multi-source data sets in the same geographic coordinate system and the corresponding water areas in the water conservancy project, so as to analyze the correlation strength and influence relationship path between each meteorological element and topographic element and the water area variable, determine the influence relationship between meteorological elements and evaporation, infiltration, and surface runoff, thereby affecting the corresponding water level and flow rate of the water area, and study the influence relationship between topography and water flow resistance, confluence path, and water body storage capacity, thereby affecting the corresponding water level and flow rate of the water area, so as to take the meteorological, topographic and water area related variables as nodes and the influence relationship between them as edges, and obtain the water area-meteorology-topography correlation network;

[0132] In the embodiments of the present invention, by using the NetworkX library of Python, based on the physical property analysis results reflecting the internal laws of meteorology and terrain, a correlation relationship network is constructed between the corresponding regional multi-source data sets in the same geographic coordinate system and the water area within the water conservancy project. The meteorological element distribution layer, terrain element layer, and relevant data of the water area, such as water level and flow velocity data, are exported from ArcGIS and organized into a format that can be processed by Python. Meteorological elements (such as rainfall, temperature, air pressure, wind speed), terrain elements (such as terrain elevation, slope, aspect), and water area variables (such as water level, flow velocity) are used as nodes. By analyzing the physical property analysis results, the influence relationships between the elements are determined as edges. For example, according to meteorological principles, an increase in rainfall will lead to an increase in surface runoff, which in turn affects the water level and flow velocity of the water area. Therefore, an edge is established between the rainfall node and the water level and flow velocity nodes of the water area in the network. By studying geomechanics and hydrological principles, the relationship between the terrain slope and the flow resistance is determined, and an edge is established between the terrain slope node and the flow resistance node. Then, based on the relationship between the flow resistance and the water area flow velocity, an edge is established between the relevant nodes. Finally, the variables related to meteorology, terrain, and water area are used as nodes, and the influence relationships between them are used as edges to obtain the water area - meteorology - terrain correlation relationship network.

[0133] Step S34: Based on the water area - meteorology - terrain correlation relationship network, conduct water area potential impact mining and analysis on the water area water level data and water area flow velocity data, so as to mine and analyze the meteorological and terrain elements corresponding to the specific significant impacts on the water area water level and flow velocity, including precipitation intensity, wind speed, terrain slope, and terrain water system connectivity, to obtain the meteorological potential factors and terrain potential factors corresponding to the water area of the water conservancy project.

[0134] In the embodiment of the present invention, in Python, by using the analysis function of the NetworkX library, the potential impact of water area on water level data and water flow velocity data is mined and analyzed based on the water area - meteorology - terrain correlation network. By traversing the correlation network, the impact intensity of each node (meteorological and terrain elements) on the water level and flow velocity nodes of the water area is calculated. For example, for the precipitation intensity node, the weights and quantities of the paths between it and the water level and flow velocity nodes are analyzed. If there are multiple strong correlation paths, it indicates that the precipitation intensity has a significant impact on the water level and flow velocity of the water area. For the wind speed node, the correlation with the water area - related nodes is also analyzed. For the terrain slope and terrain water system connectivity nodes, according to their connection relationships and impact paths in the network, the degree of their impact on the water level and flow velocity of the water area is judged. The meteorological and terrain elements that have a specific significant impact on the water level and flow velocity of the water area are screened out, such as precipitation intensity, wind speed, terrain slope, and terrain water system connectivity, and organized into a data set to obtain the meteorological potential factors and terrain potential factors corresponding to the water area of the water conservancy project, providing key impact factor data for evaluating the operation status of the water conservancy project.

[0135] Further, step S3 includes the following steps:

[0136] Step S41: Obtain the corresponding dam seepage displacement rate and the cumulative dam displacement amount through the dam seepage displacement of the water conservancy dam.

[0137] In the embodiment of the present invention, the dam seepage displacement obtained from the previous analysis is quantitatively calculated within a period of time, with data collected every 10 minutes and sent to the data collector of the monitoring center through wired transmission. In the monitoring center, data processing software is used to analyze the collected dam seepage displacement. By calculating the ratio of the difference between two adjacent collected data to the time interval, the dam seepage displacement rate is obtained. For example, if the dam displacement changes from 100 mm to 102 mm within 10 minutes, the displacement rate is (102 - 100) ÷ 10 = 0.2 mm / min. At the same time, the displacement data collected each time is accumulated to obtain the cumulative dam displacement amount, and finally the corresponding dam seepage displacement rate and the cumulative dam displacement amount are obtained.

[0138] Step S42: Obtain the corresponding upstream - downstream water level difference and water flow velocity through the water area of the water conservancy project.

[0139] In the embodiment of the present invention, a water level sensor and a current meter are respectively installed upstream and downstream of the water area of the water conservancy project. The water level sensor uses a pressure type water level gauge to measure water level data every 15 minutes; the current meter uses a Doppler current meter to measure water flow velocity data every 20 minutes. These devices transmit the data to the server of the monitoring center in real time through a wireless communication module. On the server, a database management system is used to store the collected data. By querying the water level data of the upstream and downstream at the same moment in the database, the difference between the two is calculated to obtain the water level difference between the upstream and downstream. For the water flow velocity data, the average value of the measured values within a certain time period (such as 1 hour) is taken as the water flow velocity of this time period, and finally the corresponding water level difference between the upstream and downstream and the water flow velocity are obtained.

[0140] Step S43: Calculate the opening degree matching degree between the corresponding upstream and downstream water level differences and water flow velocities based on the opening degree of the water conservancy sluice, so as to obtain the matching degree between the sluice opening degree and the upstream and downstream water level differences and water flow velocities;

[0141] In the embodiment of the present invention, by running a dedicated opening matching degree calculation program on the server of the monitoring center, this program analyzes the relationship among the opening of the water conservancy sluice, the water level difference between the upstream and downstream, and the water flow velocity based on the mathematical model established according to the hydraulic principle and historical data. The program first divides multiple intervals according to different value ranges of the sluice opening. For each interval, combined with the historical data of the water level difference between the upstream and downstream and the water flow velocity, the theoretically optimal matching value is determined. Then, the current water level difference between the upstream and downstream and the water flow velocity are substituted into the model to calculate the actual matching value. By comparing the actual matching value with the theoretical optimal matching value, the matching degree among the sluice opening, the water level difference between the upstream and downstream, and the water flow velocity is finally obtained and presented in the form of a percentage. For example, 100 sets of measured values of the water level difference between the upstream and downstream and the water flow velocity corresponding to different sluice openings such as 10%, 20%, 30%... of the sluice opening in the past year are collected. Using the regression analysis method, these historical data are processed. Taking the sluice opening as the X variable, the water level difference between the upstream and downstream as the Y1 variable, and the water flow velocity as the Y2 variable, regression equations Y1 = a1X + b1 and Y2 = a2X + b2 are constructed, where a1, b1, a2, and b2 are coefficients obtained through regression calculation. These equations are the theoretical relationship models among the sluice opening, the water level difference between the upstream and downstream, and the water flow velocity. When it is necessary to calculate the matching degree among the current sluice opening, the water level difference between the upstream and downstream, and the water flow velocity, first obtain the current sluice opening value X0, substitute it into the above regression equations, and get the theoretically upstream and downstream water level difference Y1_theory = a1X0 + b1 and the theoretical water flow velocity Y2_theory = a2X0 + b2. At the same time, obtain the current actual upstream and downstream water level difference Y1_actual and water flow velocity Y2_actual from the real-time monitoring system. For the matching degree of the water level difference between the upstream and downstream, by calculating |Y1_actual - Y1_theory|÷Y1_theory×100%, the deviation percentage of the water level difference between the upstream and downstream is obtained. For example, if Y1_theory is 5 meters and Y1_actual is 5.2 meters, the deviation percentage of the water level difference between the upstream and downstream is |5.2 - 5|÷5×100% = 4%.For the matching degree of the water flow velocity, calculate |Y2_actual - Y2_theoretical| ÷ Y2_theoretical × 100% in the same way to obtain the deviation percentage of the water flow velocity. For example, if Y2_theoretical is 3 m / s and Y2_actual is 3.1 m / s, the deviation percentage of the water flow velocity is |3.1 - 3| ÷ 3 × 100% ≈ 3.33%. Considering the deviation percentage of the upstream and downstream water level difference and the water flow velocity comprehensively, calculate the overall matching degree by using the weighted average method. Assume that the weight of the upstream and downstream water level difference is 0.6 and the weight of the water flow velocity is 0.4. Then the overall matching degree = the deviation percentage of the upstream and downstream water level difference × 0.6 + the deviation percentage of the water flow velocity × 0.4. Taking the above data as an example, the overall matching degree = 4% × 0.6 + 3.33% × 0.4 ≈ 3.73%. Finally, use 1 - the overall matching degree to obtain the matching degree between the sluice opening and the upstream and downstream water level difference and the water flow velocity, that is, 1 - 3.73% = 96.27%. Finally, obtain the matching degree between the sluice opening and the upstream and downstream water level difference and the water flow velocity.

[0142] Step S44: Quantify the water conservancy operation risk of the corresponding operation facilities of the water conservancy project by assigning corresponding water conservancy influence weights to the seepage deformation displacement rate of the dam body, the cumulative displacement of the dam body, and the matching degree between the sluice opening and the upstream and downstream water level difference and the water flow velocity, and combining the meteorological potential factors and topographic potential factors corresponding to the water area of the water conservancy project, so as to obtain the water conservancy operation risk score;

[0143] In the embodiment of the present invention, on the server, pre-set the water conservancy influence weights of the seepage deformation displacement rate of the dam body, the cumulative displacement of the dam body, and the matching degree between the sluice opening and the upstream and downstream water level difference and the water flow velocity, which are 0.3, 0.2, and 0.5 respectively. At the same time, combine the meteorological potential factors and topographic potential factors corresponding to the water area of the water conservancy project. The meteorological potential factors are obtained in real time through a meteorological station, including information such as precipitation intensity and wind speed; the topographic potential factors are determined according to the previous geological exploration data, such as topographic slope and topographic water system connectivity, etc. Convert the meteorological potential factors and topographic potential factors into quantified scores, and use the weighted summation method to perform water conservancy operation risk quantification calculation, that is, the water conservancy project operation risk score = the seepage deformation displacement rate of the dam body × 0.3 + the cumulative displacement of the dam body × 0.2 + the matching degree × 0.5 + the meteorological potential factor score + the topographic potential factor score. Finally, obtain the water conservancy project operation risk score.

[0144] Step S45: Perform emergency warning control on the corresponding operation facilities of the water conservancy project according to the water conservancy project operation risk score to generate an emergency control plan for the operation state of the water conservancy project.

[0145] In an embodiment of the present invention, by setting a preset operation risk threshold of 80 points on the server, the server compares the calculated operation risk score of the water conservancy project with the preset operation risk threshold at regular time intervals (such as every hour). If the operation risk score of the water conservancy project is less than 80 points, the server continues to receive and process data from various sensors, continuously monitors the operation facilities corresponding to the water conservancy project. If the operation risk score of the water conservancy project is greater than or equal to 80 points, the server automatically triggers an early warning mechanism, sends an early warning signal to the water conservancy project management personnel through the SMS platform, and at the same time calls a pre-written emergency plan generation program. This program generates a corresponding plan for adjusting the sluice opening, controlling the water level of the reservoir area, and reducing the displacement pressure of the dam body according to the specific situation of the risk, combining with the hydraulic model and historical cases, to form an emergency control plan for the operation state of the water conservancy project.

[0146] Further, the emergency early warning control of the operation facilities corresponding to the water conservancy project in step S45 includes comparing and judging the operation risk score of the water conservancy project according to the preset operation risk threshold. If the operation risk score of the water conservancy project is less than the preset operation risk threshold, the operation facilities corresponding to the water conservancy project continue to be monitored; if the operation risk score of the water conservancy project is greater than or equal to the preset operation risk threshold, the operation facilities automatically start the early warning mechanism to send an early warning signal to the water conservancy project management personnel, and respond to generate a corresponding plan for adjusting the sluice opening, controlling the water level of the reservoir area, and reducing the displacement pressure of the dam body, so as to generate an emergency control plan for the operation state of the water conservancy project.

[0147] Further, the present invention also provides a monitoring system for the operation state of a water conservancy project, which is used to execute the monitoring method for the operation state of the water conservancy project as described above.
