Description

Technical Field

[0001] The present invention relates to the technical field of groundwater extraction, and particularly to a groundwater extraction planning method, device, equipment and storage medium. Background Art

[0002] Groundwater extraction planning refers to scientifically and reasonably arranging and laying out the extraction of groundwater according to the regional water resource conditions, social and economic development needs, and ecological environment protection requirements, etc., including determining reasonable extraction volumes, the layout of extraction wells, extraction times, etc., to achieve the sustainable utilization of groundwater, while ensuring the sustainable development of the economy and society and the stability of the ecological environment.

[0003] In the actual scenario of urban groundwater extraction and application, the following factors need to be considered in groundwater extraction planning: (1) There are usually a large number of groundwater extraction points and a large number of groundwater demand points within the urban area. The water storage capacity and recovery speed of each groundwater extraction point are different, and the water demand of each groundwater demand point is also different. When planning the extraction and transportation of groundwater for each groundwater extraction point, not only the water demand of each demand point and the extraction limitations of each groundwater extraction point need to be considered, but also the transportation cost between the groundwater extraction point and the groundwater demand point needs to be considered. Under the influence and limitation of various factors, the difficulty of groundwater extraction planning and scheduling within the urban area is increased; (2) In some cases, different groundwater demand points have different water quality requirements (for example, the required water quality grades for domestic water, industrial water, agricultural water, and ecological water show a decreasing demand. Groundwater demand points with low water quality requirements can be compatible with groundwater of high water quality grades, while groundwater demand points with high water quality requirements cannot be compatible with groundwater of low water quality grades), and the different hydrogeological conditions of each groundwater extraction point result in different water qualities of the extracted groundwater. In such situations and limiting conditions, the groundwater extraction planning within the urban area becomes more complex.

[0004] Therefore, how to improve the scientificity and rationality of the groundwater extraction and transportation planning from groundwater extraction points to groundwater demand points within the urban area, while ensuring the different supply demands of each groundwater demand point within the urban area, improving the extraction and transportation efficiency and reducing the scheduling cost, is a technical problem that urgently needs to be solved. Summary of the Invention

[0057] Send the groundwater pumping strategy to the pumping equipment and transportation pipeline control components of each groundwater pumping point, so that each groundwater pumping point performs groundwater pumping and transportation during the pumping period.

[0058] The specific embodiments of the present invention applied to the device are basically the same as those of the following embodiments of the groundwater pumping planning method, and will not be elaborated here.

[0059] An embodiment of the present invention provides a groundwater pumping planning method, referring to Figure 2 , Figure 2 which is a schematic flowchart of an embodiment of the groundwater pumping planning method of the present invention.

[0060] In this embodiment, a groundwater pumping planning method includes the following steps:

[0061] S100: Obtain the pumping deployment information of several groundwater pumping points in the target urban area; wherein, the pumping deployment information includes hydrogeological information and transportation pipeline deployment information;

[0062] S200: Based on the hydrogeological information, determine the pumping water level threshold and water quality information for each groundwater pumping point, and construct a groundwater pumping plan database for different water quality grades in the target urban area;

[0063] S300: When receiving a groundwater pumping plan request for a target time period, obtain the predicted water demand information in the target urban area during the target time period; wherein, the predicted water demand information includes the water volume demand and water quality demand of each groundwater demand point;

[0064] S400: According to the transportation pipeline deployment information of each groundwater extraction point within the target urban area and the groundwater extraction planning database for different water quality grades, considering the water volume demand and water quality demand of each groundwater demand point, using the water volume demand and water quality demand of each groundwater demand point as constraint conditions, and taking the groundwater usage cost determined by the transportation pipeline deployment information as the optimization objective, plan the groundwater extraction strategy;

[0065] S500: Send the groundwater extraction strategy to the extraction equipment and transportation pipeline control components of each groundwater extraction point, so that each groundwater extraction point can perform groundwater extraction and transportation during the extraction period.

[0066] It should be noted that in the actual scenario of urban groundwater extraction and application, the following factors need to be considered in groundwater extraction planning: (1) There are usually a large number of groundwater extraction points and a large number of groundwater demand points within the urban area. The water storage capacity and recovery speed of each groundwater extraction point are different, and the water volume demand of each groundwater demand point is also different. When planning the groundwater extraction and transportation for each groundwater extraction point, not only the water volume demand of each demand point and the extraction limit of each groundwater extraction point need to be considered, but also the transportation cost between the groundwater extraction point and the groundwater demand point needs to be considered. Under the influence and restriction of various factors, the difficulty of groundwater extraction planning and scheduling within the urban area is increased; (2) In some cases, different groundwater demand points have different water quality requirements (for example, the water quality grades required for domestic water, industrial water, agricultural water, and ecological water show a decreasing demand. Groundwater demand points with low water quality requirements can be compatible with groundwater of high water quality grades, while groundwater demand points with high water quality requirements cannot be compatible with groundwater of low water quality grades), and the different hydrogeological conditions of each groundwater extraction point result in different water qualities of the extracted groundwater. In such situations and restrictive conditions, the groundwater extraction planning within the urban area becomes more complex.

[0067] To solve the above problems, in this embodiment, by obtaining the hydrogeological information and transportation pipeline deployment information of several groundwater extraction points within the target urban area, a groundwater extraction planning database with different water quality grades is constructed using the hydrogeological information. By obtaining the water volume demand and water quality demand of each groundwater demand point in the target urban area, according to the transportation pipeline deployment information of each groundwater extraction point within the target urban area and the groundwater extraction planning database for different water quality grades, with the water volume demand and water quality demand of each groundwater demand point as the constraint conditions and the groundwater usage cost determined by the transportation pipeline deployment information as the optimization target, a groundwater extraction strategy is planned. Thus, the scientificity and rationality of the groundwater extraction and transportation planning from the groundwater extraction points to the groundwater demand points within the urban area are improved, while ensuring the different supply demands of each groundwater demand point within the urban area, enhancing the extraction and transportation efficiency, and reducing the scheduling cost.

[0068] In a preferred embodiment, the steps of obtaining the extraction deployment information of several groundwater extraction points within the target urban area specifically include:

[0069] S110: Access the hydrogeological exploration database, extract several aquifer characteristics and recharge source characteristics of each groundwater extraction point recorded in the hydrogeological exploration database, and generate hydrogeological information;

[0070] S120: Obtain the groundwater transportation pipeline layout map of the target urban area, extract the first location information of each groundwater extraction point, the second location information of each groundwater demand point, and the groundwater transportation pipeline paths from each groundwater extraction point to several groundwater demand points connected by its transportation pipeline, and generate transportation pipeline deployment information.

[0071] In this embodiment, by accessing the hydrogeological exploration database, extracting several aquifer characteristics and recharge source characteristics of each groundwater extraction point, and generating hydrogeological information, and by extracting the groundwater transportation pipeline paths in the groundwater transportation pipeline layout map to generate transportation pipeline deployment information. In this way, through the acquisition of hydrogeological information and transportation pipeline deployment information, data support is provided for the subsequent groundwater extraction and transportation planning from the groundwater extraction points to the groundwater demand points within the urban area.

[0072] In a preferred embodiment, the steps of determining the extraction water level threshold and water quality information of each groundwater extraction point based on the hydrogeological information and constructing a groundwater extraction planning database for different water quality grades in the target urban area specifically include:

[0073] S210: Based on the hydrogeological information, determine the extraction water level threshold and water quality information of each groundwater extraction point, and use the water quality information to classify the water quality grades of several groundwater extraction points;

[0074] S220: Construct a groundwater extraction planning database for different water quality grades in the target urban area according to the water quality grade and extraction water level threshold of each groundwater extraction point.

[0075] Furthermore, based on the hydrogeological information, determine the extraction water level threshold and water quality information of each groundwater extraction point, and use the water quality information to perform the steps of dividing the water quality grades of several groundwater extraction points, specifically including:

[0076] S211: Extract several aquifer characteristics and recharge source characteristics in the hydrogeological information, construct an input sample for identifying the extraction water level threshold, and input it into a pre-trained groundwater extraction water level threshold prediction model to obtain the extraction water level threshold of each groundwater extraction point;

[0077] Among them, the groundwater extraction water level threshold prediction model is configured to be a prediction model obtained by training an initial convolutional neural network with an extraction water level threshold training sample during the training stage until the training times or training convergence are reached. The extraction water level threshold training sample includes a data group composed of the groundwater level value of a reference groundwater extraction point when it is determined to be over-extracted and the aquifer characteristics and recharge source characteristics corresponding to the reference groundwater extraction point. The determination of being over-extracted of groundwater means that at least one of the geological problem accidents, ecological problem accidents, soil problem accidents, or water resource problem accidents caused by too low groundwater level occurs in the key area of the reference groundwater extraction point;

[0078] S212: Take the cumulative value of the water quality impact quantification values corresponding to several aquifer characteristics and recharge source characteristics as the water quality information of each groundwater extraction point, and determine the water quality grade of each groundwater extraction point according to the position of the cumulative value of the water quality impact quantification in the section corresponding to different water quality grades;

[0079] Among them, the conversion of aquifer characteristics and recharge source characteristics into water quality impact quantification values is configured to use a pre-defined relationship mapping table between characteristic values and water quality impact quantification values to match the water quality impact quantification values corresponding to each aquifer characteristic and recharge source characteristic in the relationship mapping table.

[0080] In this embodiment, based on several aquifer characteristics and recharge source characteristics in the hydrogeological information, using a pre-trained groundwater extraction water level threshold prediction model, by analyzing the relationship between the groundwater level value when the reference groundwater extraction point is determined to be over-extracted during the training stage and the corresponding aquifer characteristics and recharge source characteristics, the extraction water level threshold for each groundwater extraction point is determined. At the same time, based on several aquifer characteristics and recharge source characteristics in the hydrogeological information, the water quality impact quantification value of each characteristic is matched using a pre-defined relationship mapping table between the characteristic value and the water quality impact quantification value, and the cumulative value of the water quality impact quantification value is used to determine the water quality grade of each groundwater extraction point.

[0081] Furthermore, according to the water quality grade and extraction water level threshold of each groundwater extraction point, the steps of constructing a groundwater extraction planning database for different water quality grades in the target urban area specifically include:

[0082] S221: According to the water quality grade of each groundwater extraction point, the groundwater extraction points belonging to the same water quality grade are classified into one category, and an initial groundwater extraction planning database for each category is established;

[0083] S222: Extract the extraction water level threshold corresponding to each groundwater extraction point, and put the extraction water level threshold and the identification information of the groundwater extraction point as a data pair into the groundwater extraction planning database of the category to which it belongs, to obtain a groundwater extraction planning database for different water quality grades in the target urban area.

[0084] In this embodiment, after obtaining the water quality grade and extraction water level threshold of each groundwater extraction point, first establish an initial groundwater extraction planning database for each category, and then put the extraction water level threshold of each groundwater extraction point in the category and the identification information of the groundwater extraction point into the groundwater extraction planning database, so as to realize the establishment of a groundwater extraction planning database for different water quality grades.

[0085] In a preferred embodiment, when receiving a groundwater extraction planning request for a target period, the steps of obtaining the water use demand prediction information of the target urban area in the target period specifically include:

[0086] S310: When receiving a groundwater extraction planning request for a target period, obtain the water use demand prediction information of each water user in the target urban area in the target period;

[0087] S320: According to the water access relationship between each water user and the groundwater demand point, distribute the water use demand prediction information of each water user to the corresponding groundwater demand point, and generate the water quantity demand and water quality demand for each groundwater demand point in the target urban area in the target period.

[0088] On this basis, according to the transportation pipeline deployment information of each groundwater extraction point in the target urban area and the groundwater extraction planning database for different water quality grades, considering the water volume demand and water quality demand of each groundwater demand point, with the water volume demand and water quality demand of each groundwater demand point as the constraint conditions, and taking the groundwater usage cost determined by the transportation pipeline deployment information as the optimization objective, plan the steps of the groundwater extraction strategy, specifically including:

[0089] S410: Obtain the target groundwater level at the initial moment of the target period for each groundwater extraction point, extract several groundwater extraction volumes from the recorded target groundwater level to the extraction water level threshold in the historical extraction data of each groundwater extraction point, and take the average value of the several groundwater extraction volumes as the groundwater safe extraction volume of each groundwater extraction point in the target period;

[0090] S420: According to the groundwater transportation pipeline path in the transportation pipeline deployment information of each groundwater extraction point in the target urban area and the groundwater extraction planning database for different water quality grades, considering the water volume demand and water quality demand of each groundwater demand point, taking that the water quality grade of each groundwater extraction point is higher than the water quality grade corresponding to the water quality demand of each assigned groundwater demand point as the first constraint condition, taking that the groundwater safe extraction volume of each groundwater extraction point is greater than the water demand corresponding to the water volume demand of each assigned groundwater demand point as the second constraint condition, taking that there is a groundwater transportation pipeline path between each groundwater extraction point and several assigned groundwater demand points as the third constraint condition, and taking the shortest unit volume transportation distance of groundwater jointly determined by the water demand of each groundwater demand point and the groundwater transportation pipeline path from each groundwater extraction point to each groundwater demand point as the optimization objective, optimize and solve the several groundwater demand points assigned to each groundwater extraction point in the target period;

[0091] S430: According to the several groundwater demand points assigned to each groundwater extraction point in the target period and the water demand of each groundwater demand point, plan the groundwater extraction strategy of the target urban area in the target period.

[0092] In this embodiment, first, by obtaining the historical extraction data of each groundwater extraction point, the safe groundwater extraction volume of each groundwater extraction point in the target period is estimated. Then, by considering the water quantity demand and water quality demand of each groundwater demand point, with the water quality demand as the first constraint condition, the water quantity demand as the second constraint condition, and the existence of the groundwater transportation pipeline path as the third constraint condition, and taking the shortest groundwater unit volume transportation distance jointly determined by the water demand of each groundwater demand point and the groundwater transportation pipeline path from each groundwater extraction point to each groundwater demand point as the optimization objective, the optimization is solved to determine several groundwater demand points assigned to each groundwater extraction point in the target period. Furthermore, a groundwater extraction strategy composed of several groundwater demand points assigned to each groundwater extraction point in the target period and the water demand of each groundwater demand point is generated, which improves the scientificity and rationality of the groundwater extraction and transportation planning from groundwater extraction points to groundwater demand points within the urban area, while ensuring different supply demands of each groundwater demand point within the urban area, improving the extraction and transportation efficiency, and reducing the scheduling cost.
