Traditional water conservancy information monitoring systems have many deficiencies. For example, the monitoring scope is limited, often only able to focus on a single water area or a specific region, and it is impossible to achieve comprehensive monitoring of the entire basin, resulting in blind spots in water resources scheduling. At the same time, the data processing and analysis capabilities are insufficient, and it is difficult to extract useful information from a large amount of data. In addition, there are also deficiencies in information integration and coordination in existing systems. They cannot well combine water conservancy information with environmental information, and it is difficult to achieve comprehensive and scientific water resources management.

[0026] In this embodiment, the water conservancy monitoring targets may be water level, fluid flow rate, water quality indicators, etc., and the environmental monitoring targets may be rainfall, temperature, wind speed, etc.

[0027] In this embodiment, each water conservancy sensor in the water conservancy sensor group corresponds to a water conservancy monitoring target, and each environmental sensor in the environmental sensor group corresponds to an environmental monitoring target.

[0031] In this embodiment, the real-time environmental information represents the set of sub-information of multiple environmental monitoring targets (such as temperature, humidity) collected by the environmental sensor group at the acquisition timestamp.

[0032] Beneficial effects of the above technical solution: By collecting the real-time water conservancy information of the target water area in real time and collecting the real-time environmental information of the target water area in real time, the data accuracy can be improved, providing data support for determining the predicted water conservancy information.

[0033] Embodiment 3: The embodiment of the present invention provides a water conservancy information monitoring system, an analysis module, including: Water conservancy cycle set unit: Perform periodic analysis on the historical water conservancy information of the target water area obtained to obtain the water conservancy cycle set of the target water area and the water conservancy cycle vector of each water conservancy sub-cycle in the water conservancy cycle set, where the historical water conservancy information includes the historical water conservancy sub-information of multiple water conservancy monitoring targets at multiple historical timestamps; Environmental cycle set unit: Perform periodic analysis on the historical environmental information of the target water area obtained to obtain the environmental cycle set of the target water area and the environmental cycle vector of each environmental sub-cycle in the environmental cycle set, where the historical environmental information includes the historical environmental sub-information of multiple environmental monitoring targets at multiple historical timestamps; Period matching pair set unit: Based on the water conservancy cycle set and the environmental cycle set, determine the period difference between any water conservancy sub-cycle in the water conservancy cycle set and any environmental sub-cycle in the environmental cycle set, and determine the period matching pair set of the target water area.

[0034] In this embodiment, the historical water conservancy sub-information of water conservancy monitoring targets such as water level and fluid flow rate at multiple historical timestamps of the target water area is obtained. The periodic analysis can be to use the Fourier transform to convert the water conservancy information in the time domain to the frequency domain, analyze the frequency components to determine the period; wavelet analysis dissects from both the time and frequency domains simultaneously to identify the periods of different time scales. Thus, all water conservancy cycles are determined to form a water conservancy cycle set. For each water conservancy sub-cycle in the set, key features such as the change amplitude are extracted to form a water conservancy cycle vector for accurately describing the characteristics of the sub-cycle.

[0035] In this embodiment, the water conservancy cycle set represents the summary of all identified water conservancy-related cycles in the target water area.

[0036] In this embodiment, the water conservancy sub-cycle represents a single cycle in the water conservancy cycle set.

[0037] In this embodiment, the water conservancy cycle vector represents a vector describing the characteristics of the water conservancy sub-cycle, including information such as cycle length and amplitude.

[0038] In this embodiment, similar to the operation of the water conservancy cycle set unit, historical environmental sub-information of environmental monitoring targets such as temperature and precipitation is collected at multiple historical timestamps in the target water area. The periodic analysis can be performed through Fourier transform and wavelet analysis to obtain the environmental cycle set, that is, the set of all environment-related cycles. For each environmental sub-cycle, features such as the fluctuation range are extracted to form an environmental cycle vector to characterize the sub-cycle.

[0039] In this embodiment, the environmental cycle set represents the summary of all environment-related cycles in the target water area.

[0040] In this embodiment, the environmental sub-cycle represents a single cycle in the environmental cycle set.

[0041] In this embodiment, the environmental cycle vector represents a vector describing the characteristics of the environmental sub-cycle, covering cycle-related characteristic data.

[0042] In this embodiment, for each water conservancy sub-cycle in the water conservancy cycle set, the cycle difference is calculated one by one with each environmental sub-cycle in the environmental cycle set. The water conservancy sub-cycles and environmental sub-cycles with differences within a reasonable range are paired, and these pairs form the cycle matching pair set.

[0043] In this embodiment, the cycle matching pair set unit: based on the water conservancy cycle set and the environmental cycle set, determine the cycle difference between any one water conservancy sub-cycle in the water conservancy cycle set and any one environmental sub-cycle in the environmental cycle set, and the determination formula for the cycle matching pair set of the target water area can be: ; Wherein, represents the cycle matching pair set of the target water area, represents that the i-th water conservancy sub-cycle in the water conservancy cycle set of the target water area and the j-th environmental sub-cycle in the environmental cycle set are a pair of cycle matching pairs in the cycle matching pair set, represents the water conservancy cycle set of the target water area, represents the environmental cycle set of the target water area, represents the i-th water conservancy sub-cycle in the water conservancy cycle set of the target water area, represents the j-th environmental sub-cycle in the set of environmental cycles of the target water area, represents the smaller value of the i-th hydraulic sub-cycle in the set of hydraulic cycles of the target water area and the j-th environmental sub-cycle in the set of environmental cycles, represents the tolerance threshold, represents the cycle difference between the i-th hydraulic sub-cycle in the set of hydraulic cycles of the target water area and the j-th environmental sub-cycle in the set of environmental cycles.

[0044] In this embodiment, it can be 0.1, that is, a 10% deviation is allowed, and it can be 0.05 when the accuracy requirement of hydraulic monitoring is high.

[0045] Beneficial effects of the above technical solution: By obtaining and analyzing the historical hydraulic information and historical environmental information of the target water area, and determining the set of cycle matching pairs of the target water area, the internal relationship between the hydraulic cycle and the environmental cycle can be determined, improving the prediction accuracy.

[0046] Embodiment 4: The embodiment of the present invention provides a hydraulic information monitoring system, and the analysis module further includes: First specified time period unit: If there is exactly one pair of cycle matching pairs in the cycle matching set, determine the cycle matching pair as the specified matching pair of the target area, and determine the smaller hydraulic sub-cycle or environmental sub-cycle in the specified matching pair as the specified time period of the target water area; Second specified time period unit: If there are multiple pairs of cycle matching pairs in the cycle matching set, select the cycle matching pair with the smallest cycle difference in the set of cycle matching pairs as the specified matching pair of the target area, and determine the smaller hydraulic sub-cycle or environmental sub-cycle in the specified matching pair as the specified time period of the target water area; Hydraulic-environment dominant unit: Obtain the hydraulic-environment dominance of the target water area, where the hydraulic-environment dominance includes engineering regulation dominance and environmental drive dominance; Third specified time period unit: If the cycle matching set is empty, based on all the cycle differences between any one hydraulic sub-cycle in the set of hydraulic cycles and any one environmental sub-cycle in the set of environmental cycles, and the hydraulic-environment dominance of the target water area, determine the specified matching pair and the specified time period of the target water area; Cycle hydraulic information unit: Based on the specified time period of the target water area, perform cycle division on the historical hydraulic information to determine the cycle hydraulic information, where the cycle hydraulic information includes cycle hydraulic sub-information within multiple specified time periods, and the cycle hydraulic sub-information includes the historical hydraulic sub-information of multiple hydraulic monitoring targets at all cycle timestamps within the specified time period; Periodic environmental information unit: Divide the historical environmental information based on the specified time period of the target water area to determine the periodic environmental information. Among them, the periodic environmental information includes periodic environmental sub-information within multiple specified time periods, and the periodic environmental sub-information includes the historical environmental sub-information of multiple environmental monitoring targets at all periodic timestamps within the specified time period.

[0047] In this embodiment, when there is only one pair of periodic matching pairs in the periodic matching set, this unique pair is determined as the specified matching pair of the target area. Then, compare the water conservancy sub-period and the environmental sub-period in the specified matching pair, and select the shorter one as the specified time period of the target water area. This is based on the fact that in the case of a single matching pair, the shorter period can more accurately reflect the periodic characteristics of the area.

[0048] In this embodiment, the specified matching pair refers to a pair composed of the water conservancy sub-period and the environmental sub-period selected for determining the specified time period.

[0049] In this embodiment, if there are multiple pairs of periodic matching pairs in the periodic matching set, calculate the period difference of each pair, and select the pair with the smallest difference as the specified matching pair of the target area. Similarly, find the shorter water conservancy sub-period or environmental sub-period from this pair of specified matching pairs, and determine it as the specified time period of the target water area. By selecting the matching pair with the smallest difference, the synchronization of the water conservancy and environmental periods can be maximally ensured, making the specified time period more representative.

[0050] In this embodiment, comprehensively consider various factors of the target water area, such as the operation and scheduling intensity of water conservancy projects and the degree of influence of natural environmental factors on the water area state, etc., to judge whether the water area is dominated by engineering regulation, that is, human-built water conservancy projects (such as dams, sluices, etc.) play a major controlling role in the water level, fluid flow rate, etc. of the water area; or is dominated by environmental drive, that is, natural meteorological, geological and other environmental factors have a greater impact on the water area.

[0051] In this embodiment, engineering regulation dominance means that the period of the target water area is more affected by engineering regulation (such as reservoir operation).

[0052] In this embodiment, environmental drive dominance means that the target water area is a natural river channel, etc., and is more affected by the environment.

[0053] In this embodiment, based on the determined specified time period of the target water area, divide the historical water conservancy information. Cut the historical water conservancy information according to the specified time period. The historical water conservancy sub-information of all water conservancy monitoring targets included in each period at each timestamp within the period constitutes a periodic water conservancy sub-information. All these periodic water conservancy sub-informations are summarized to form periodic water conservancy information.

[0054] In this embodiment, similar to the periodic water conservancy information unit, historical environmental information is divided based on a specified time period. For each specified time period, the historical environmental sub-information of all environmental monitoring targets at each timestamp within this period is aggregated into a periodic environmental sub-information, and numerous periodic environmental sub-informations constitute periodic environmental information, which helps analyze the changes in environmental information within each period.

[0055] Beneficial effects of the above technical solution: By determining the specified time period of the target water area, as well as the periodic water conservancy information and periodic environmental information, in-depth analysis of the laws of water conservancy and environmental changes can be achieved, further improving the adaptability and prediction accuracy of the prediction model, and enhancing the dynamic monitoring accuracy of water conservancy information.

[0056] Embodiment 5: The embodiment of the present invention provides a water conservancy information monitoring system, a third specified time period unit, including: Designated matching pair sub-unit: If the periodic matching set is empty, select the water conservancy sub-period and the environmental sub-period corresponding to the minimum periodic difference between the water conservancy period set and the environmental period set as the designated matching pair for the target area; Engineering regulation leading sub-unit: If the water conservancy-environment leading of the target water area is engineering regulation leading, determine the water conservancy sub-period in the designated matching pair with an empty periodic matching set as the specified time period of the target water area; Environmental driving leading sub-unit: If the water conservancy-environment leading of the target water area is environmental driving leading, determine the environmental sub-period in the designated matching pair with an empty periodic matching set as the specified time period of the target water area.

[0057] In this embodiment, when the periodic matching set is empty, that is, when no water conservancy and environmental period pair corresponding to the tolerance threshold can be found, the water conservancy sub-period and the environmental sub-period corresponding to the minimum periodic difference among them are selected, and this pair is determined as the designated matching pair for the target area.

[0058] In this embodiment, the minimum periodic difference represents the minimum value among the periodic differences obtained by pairwise comparison of all water conservancy sub-periods and environmental sub-periods in the water conservancy period set and the environmental period set.

[0059] In this embodiment, if it is determined that the target water area belongs to the engineering regulation leading type, that is, human-built water conservancy projects such as dams and sluices play a major controlling role in key characteristics such as the water level and fluid flow of the water area. At this time, among the designated matching pairs with an empty periodic matching set that has been determined, directly select the water conservancy sub-period as the specified time period of the target water area. This is because in the engineering regulation leading area, the periodic changes generated by the operation of water conservancy projects have the most crucial impact on the overall water area state. Using the water conservancy sub-period as the specified time period can better fit the actual water conservancy change law in this area.

[0060] In this embodiment, when the target water area is determined to be dominated by environmental drivers, that is, environmental factors such as natural meteorology (such as precipitation, temperature changes) and geology (such as soil characteristics, topography) have a more significant impact on the water area state. Then, among the specified matching pairs determined when the cycle matching set is empty, select the environmental sub-cycle as the specified time cycle of the target water area. Since environmental factors dominate the impact on the water area in such regions, using the environmental sub-cycle as the specified time cycle can better reflect the periodic characteristics of the water area driven by changes in environmental factors in this region. Beneficial effects of the above technical solution: When it is determined that the cycle matching set is empty, the specified matching pair and the specified time cycle of the target water area can improve the adaptability and flexibility of the water conservancy monitoring system, more precisely adapt to the dual impacts of natural and human factors, and provide strong support for formulating scheduling strategies.

[0061] Embodiment 6: The embodiment of the present invention provides a water conservancy information monitoring system, a prediction module, including: Mapping timestamp unit: Map the previous historical timestamp of the collected timestamp to the specified time cycle, and determine the mapping timestamp of the real-time water conservancy information and the real-time environmental information based on the specified time cycle; Start timestamp unit: Based on the specified time cycle of the target water area, and the mapping timestamp of the real-time water conservancy information and the real-time environmental information based on the specified time cycle, determine the start timestamp of the real-time water conservancy information and the real-time environmental information based on the specified time cycle; Real-time periodic environmental information unit: Based on all the real-time environmental sub-information of all environmental monitoring targets between the historical timestamp corresponding to the start timestamp of the target water area and the previous historical timestamp of the collected timestamp, determine the real-time periodic environmental information; Real-time periodic water conservancy information unit: Based on all the real-time water conservancy sub-information of all water conservancy monitoring targets between the historical timestamp corresponding to the start timestamp of the target water area and the previous historical timestamp of the collected timestamp, determine the real-time periodic water conservancy information; Mapping environmental vector unit: Extract the historical environmental sub-information of all environmental monitoring targets at the periodic timestamp corresponding to the mapping timestamp in the periodic environmental sub-information of each specified time cycle in the periodic environmental information, and determine the mapping environmental vector of each specified time cycle in the periodic environmental information based on the mapping timestamp ; Real-time environmental vector unit: Based on the historical environmental sub-information of all environmental monitoring targets at the previous historical timestamp of the collected timestamp in the real-time environmental information, determine the real-time environmental vector of the previous historical timestamp of the collected timestamp ; Environmental similarity value unit: Based on the mapped environmental vectors of each specified time period in the periodic environmental information and the real-time environmental vector of the previous historical timestamp of the acquisition timestamp , calculate the environmental similarity value of each specified time period in the periodic environmental information ; Real-time period set unit: Sort the environmental similarity values of all specified time periods in the periodic environmental information from largest to smallest, and select the specified time periods corresponding to the top specified number of environmental similarity values after sorting as the real-time period set of the real-time water conservancy information and the real-time environmental information.

[0062] In this embodiment, the acquisition timestamp represents the acquisition moment of the current real-time data, and its previous historical timestamp records the state immediately before the real-time data. The system maps this previous historical timestamp to the specified time period of the determined target water area to find its relative position in the specified time period, so as to determine the mapping timestamps of the real-time water conservancy information and the real-time environmental information based on the specified time period. For example, if the specified time period is one year, the current acquisition timestamp is May 1, 2024, and its previous historical timestamp is April 30, 2024. Through mapping, the specific position of this time in the annual cycle can be determined, such as the 120th day (assuming a year has 365 days).

[0063] In this embodiment, the mapping timestamp represents the relative time identifier corresponding to the previous historical timestamp of the acquisition timestamp in the specified time period.

[0064] In this embodiment, in combination with the specified time period of the target water area and the previously determined mapping timestamp, the start timestamps of the real-time water conservancy information and the real-time environmental information based on the specified time period are calculated. This start timestamp is a starting point based on the specified time period to ensure the integrity and coherence of subsequent data analysis. For example, if the specified time period is one month (30 days) and the mapping timestamp is the 15th day, then the start timestamp may be determined as the 1st day of this month.

[0065] In this embodiment, the start timestamp is used to define the time identifier for the start of the analysis of the real-time water conservancy and environmental information within the specified time period.

[0066] In this embodiment, based on the historical timestamp corresponding to the determined start timestamp and the previous historical timestamp of the acquisition timestamp, all real-time environmental sub-information generated by all environmental monitoring targets during this time period is filtered out, and this information is aggregated and integrated to determine the real-time periodic environmental information. For example, the historical timestamp corresponding to the start timestamp is April 1, 2024, and the previous historical timestamp of the acquisition timestamp is April 30, 2024. The real-time environmental sub-information of all environmental monitoring targets during this period constitutes the real-time periodic environmental information.

[0067] In this embodiment, similar to the real-time periodic environmental information unit, according to the historical timestamp corresponding to the start timestamp and the previous historical timestamp of the acquisition timestamp, all real-time water conservancy sub-information of all water conservancy monitoring targets during this time period is extracted, and then the real-time periodic water conservancy information is determined.

[0068] In this embodiment, for the periodic environmental sub-information of each specified time period in the periodic environmental information, all historical environmental sub-information of all environmental monitoring targets at the periodic timestamp corresponding to the mapping timestamp is found, and this information is sorted and extracted to form a vector form, which is determined as the mapping environmental vector of each specified time period in the periodic environmental information based on the mapping timestamp. For example, in the periodic environmental sub-information of an annual specified time period, if the mapping timestamp corresponds to the 120th day, all historical environmental sub-information of all environmental monitoring targets on that day is extracted to form the mapping environmental vector.

[0069] In this embodiment, directly based on the historical environmental sub-information of all environmental monitoring targets at the previous historical timestamp under the acquisition timestamp in the real-time environmental information, this information is sorted into a vector form, which is determined as the real-time environmental vector of the previous historical timestamp of the acquisition timestamp. For example, if the acquisition timestamp is May 1, 2024, and the previous historical timestamp is April 30, 2024, the historical environmental sub-information of all environmental monitoring targets (such as the temperature and precipitation on that day) on this day is formed into the real-time environmental vector.

[0070] In this embodiment, for the mapping environmental vector of each specified time period in the periodic environmental information and the real-time environmental vector of the previous historical timestamp of the acquisition timestamp, the similarity degree between the two is calculated, and the value of this similarity degree is the environmental similarity value of each specified time period in the periodic environmental information.

[0071] In this embodiment, the mapping environmental vector of the specified time period in the periodic environmental information based on the mapping timestamp can be expressed as: ; Among them, represents the mapping environmental vector of the a-th specified time period in the periodic environmental information based on the mapping timestamp, respectively represent the historical environmental sub-information of the first environmental monitoring target, the b-th environmental monitoring target, and the N1-th environmental monitoring target based on the mapping timestamp in the a-th specified time period in the periodic environmental information, where N1 represents the number of environmental monitoring targets.

[0072] In this embodiment, the real-time environmental vector of the previous historical timestamp of the acquisition timestamp : ; Among them, represents the real-time environmental vector of the previous historical timestamp of the acquisition timestamp, respectively represent the historical environmental sub-information of the first environmental monitoring target, the b-th environmental monitoring target, and the N1-th environmental monitoring target of the real-time environmental vector.

[0073] In this embodiment, calculate the environmental similarity value of each specified time period in the periodic environmental information The calculation formula can be; ; Among them, represents the environmental similarity value of the a-th specified time period in the periodic environmental information, represents the periodic decay factor, represents the start timestamp of the specified time period based on the real-time environmental information, represents the earliest timestamp among all the periodic timestamps of the a-th specified time period, represents the weight of the b-th environmental monitoring target, The value ranges of all are 0 - 1.

[0074] In this embodiment, sort the environmental similarity values of all specified time periods in the periodic environmental information from largest to smallest. Then, according to the preset specified quantity, select the specified time periods corresponding to the top specified quantity of environmental similarity values after sorting, and combine these periods together as the real-time period set of the real-time water conservancy information and the real-time environmental information. For example, if the specified quantity is 5, then select the 5 specified time periods with the largest environmental similarity values, and these periods represent the past time periods that are most similar to the current real-time environmental state.

[0075] The beneficial effects of the above technical solution: Obtaining the real-time period set based on the periodic environmental information and the real-time environmental information can enhance the adaptability and real-time performance of the prediction model, improve the prediction accuracy and reliability, and provide efficient and accurate decision support for the water conservancy monitoring system.

[0076] Embodiment 7: The embodiment of the present invention provides a water conservancy information monitoring system, a prediction module, further including: Construct a dataset unit: Extract periodic water conservancy information based on all specified time periods in the real-time period set, and determine the constructed dataset. Prediction model unit: Construct a prediction model based on the water conservancy cycle vectors of water conservancy sub-cycles in the water conservancy cycle set corresponding to the specified time period, or the environmental cycle vectors of environmental sub-cycles in the environmental cycle set, and the constructed dataset. Predict water conservancy sub-information unit: Input the real-time period water conservancy information into the prediction model, and determine the predicted water conservancy information based on the output result of the prediction model. Among them, the predicted water conservancy information includes the predicted water conservancy sub-information of multiple water conservancy monitoring targets for the acquisition timestamp.

[0077] In this embodiment, all specified time periods are obtained from the real-time period set. For each specified time period, the water conservancy information within the corresponding time period is extracted from the existing periodic water conservancy information. For example, if there are three specified time periods in the real-time period set, namely January - March 2020, July - September 2021, and April - June 2023, the information of all water conservancy monitoring targets within these three time periods is respectively extracted from the periodic water conservancy information, and the extracted information is summarized and integrated to determine the constructed dataset.

[0078] In this embodiment, the water conservancy cycle vectors of water conservancy sub-cycles in the water conservancy cycle set corresponding to the specified time period, or the environmental cycle vectors of environmental sub-cycles in the environmental cycle set, are used in combination with the previously constructed dataset to construct a prediction model. The water conservancy cycle vector contains information describing the characteristics of water conservancy sub-cycles such as cycle length and change amplitude; the environmental cycle vector contains similar information describing the characteristics of environmental sub-cycles. By combining these feature vectors with the water conservancy information in the constructed dataset and applying appropriate modeling algorithms (such as regression algorithms, neural network algorithms, etc.), a model capable of predicting water conservancy information is built.

[0079] In this embodiment, the real-time period water conservancy information is input into the already constructed prediction model. The real-time period water conservancy information is a set of real-time water conservancy sub-information of all water conservancy monitoring targets between the historical timestamp corresponding to the start timestamp and the previous historical timestamp of the acquisition timestamp. Based on the input real-time period water conservancy information and the rules it has learned internally (from the constructed dataset and cycle vectors), the prediction model outputs the prediction results for multiple water conservancy monitoring targets at the acquisition timestamp, and these prediction results constitute the predicted water conservancy information.

[0080] Beneficial effects of the above technical solution: The predicted water conservancy information is obtained based on the specified time period, the real-time period set, and the periodic water conservancy information, which can accurately predict the water conservancy information of the acquisition timestamp, provide more forward-looking and accurate data support for water conservancy management decisions, and effectively improve the prediction efficiency of water conservancy information.
