[0059] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0060] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0061] like Figure 1 The pipeline layout management method based on data analysis provided by one embodiment of the present invention comprises the following steps:

[0062] S10, obtaining environmental geological data of the assessment area, performing data preprocessing on the environmental geological data and superimposing the data with the regional distribution layer to generate environmental geological distribution data, wherein the environmental geological data includes topographic data and soil geological data;

[0063] S20, obtaining standard construction requirements corresponding to multiple types of environmental geology based on standard specifications for pipeline layout, wherein the standard construction requirements are used to characterize parameter indicators that need to be achieved in the corresponding environmental geology within the rated range of the pipeline when arranging the pipeline;

[0064] S30, splitting the regional distribution layer into unit areas, performing environmental improvement estimation based on the environmental geological distribution data of each unit area and the corresponding standard construction requirements, and obtaining various environmental construction costs of the current unit area, wherein the environmental improvement estimation is used to characterize the economic effort required to improve the current environmental geology to the parameter index;

[0065] S40, obtaining the starting and ending points of the pipeline layout, performing path planning calculations on the evaluation area based on the environmental construction costs of several unit areas, and obtaining a cost-optimal path, wherein the cost-optimal path is used to characterize the pipeline layout plan.

[0066] In this embodiment, a pipeline layout management method based on data analysis is provided. By collecting and evaluating environmental geological data and the environmental requirements for pipeline layout, the degree of transformation required for the corresponding environmental geology when arranging pipelines in various places in the assessment area is judged, and then the cost of pipeline layout can be estimated according to the unit cost of different environmental geological transformations to determine the cost optimal path for pipeline layout between points AB, so as to achieve full-process cost planning and solution output; pipeline layout is a common engineering content in many fields, and in urban infrastructure construction and weight reduction of building industrial facilities, it usually refers to water supply and drainage pipelines, heating pipelines, Gas pipelines and other livelihood infrastructures need to consider many factors in the layout of these facilities. Not only do they need to radiate to residential areas, but they also need to make multi-faceted judgments on cost, efficiency and safety. These are mainly determined by the environmental geological type and the corresponding level. For example, the cost of the length of the pipeline is fixed and calculable, but when the geological environment changes, the cost of environmental processing and transformation during laying is different. For example, under normal soil conditions, it only requires simple excavation to the predetermined depth for burial. However, if it is on hardened ground in the city, it is necessary to additionally destroy and restore the hardened road surface. For those containing The construction costs per unit distance for geological scenes with more sand and gravel or underwater are different. At the same time, the same geological environment has different degrees of specific differences (for example, the geology is too soft or the water content is too high). Therefore, in order to ensure the long-term stability of laying pipelines, it is necessary to transform the environment so that it can meet the target environmental standards for long-term laying of pipelines, which will also lead to changes in cost output. The implementation scheme adopted in this embodiment is: the geological data of the corresponding area is acquired through sensors, manual collection and the local geological environment bureau, and then the area can be grid-refined (for example, divided into 10m*10m grids), and the grid size can be adjusted according to the pipeline layout. The environmental geological specifications in the center require that the cost requirements for laying in different areas within the region be calculated, so that the optimal cost can be calculated based on the starting point of laying. The evaluation area here can be determined after evaluation based on the regional distribution that the pipeline needs to radiate. For example, if two residential areas AB need to be radiated, it can be part of the location interval at the junction of the AB areas; specifically, through data analysis, the construction cost of the terrain environment in the area between the two points of the pipeline layout is determined in the pipeline layout, including the various construction costs of digging channels for soil and rocks, and transforming unsuitable soil such as soft soil into an environment suitable for pipeline layout.

[0067] like Figure 2 As shown, as another preferred embodiment of the present invention, the step of preprocessing the environmental geological data and superimposing it with the regional distribution layer to generate the environmental geological distribution data specifically includes:

[0068] S11, obtaining topographic data of the assessment area, dividing the assessment area into characteristic areas based on the surface geological categories, wherein the characteristic areas are used to characterize the expression categories of the surface geological features of the current area;

[0069] S12, calculating characteristic gradients for a plurality of characteristic regions to generate characteristic gradient layers corresponding to the evaluation region, wherein the characteristic gradients are used to characterize drop characteristics of different geological features at a certain location, wherein the drop characteristics include ground drop and water level drop;

[0070] S13, obtaining soil geological data based on a plurality of random sampling points in the assessment area, performing geological transition fitting based on the soil geological data and the characteristic gradient layer to generate a geological distribution layer of the assessment area, wherein the geological distribution layer includes underground geological types and distribution conditions at various locations in the assessment area.

[0071] In this embodiment, the acquisition of geological distribution data is supplemented. The characteristic area here is used to express the geological features. For example, there are three sub-areas abc in the evaluation area, among which a is the water area, b is the soil area, and c is the gravel area; and the characteristic gradient layer is used to characterize the vertical drop characteristics of the geological features of these areas, such as the height change of the ground plane and the depth change drop of the water level; the soil geological data represents the corresponding specific intensity characteristics of the corresponding geological features, such as the softness and water content of the soil in area b, the density content and gravel particle size of the sand and gravel in area c, all of which will affect the construction difficulty and environmental transformation cost requirements in pipeline laying.

[0072] As another preferred embodiment of the present invention, the step of geological transition fitting includes:

[0073] Acquire groups of historically sampled soil geological data of the same geological type, and perform low-distribution density sampling grouping based on the spatial distribution of each group of soil geological data to obtain training groups and verification groups;

[0074] Setting training environment parameters based on multiple types of environmental geology defined by the standard construction requirements;

[0075] Correspondingly obtaining a variety of geological features in the collection area where the soil geological data is located, and based on the correlation of the remaining soil geological data, performing correlation binding and assigning a corresponding correlation coefficient;

[0076] Perform data fitting based on the training group and the corresponding terrain data of the array to obtain the corresponding correlation coefficient of the array, and perform fitting on the corresponding points of the verification group according to the correlation coefficient to obtain fitting verification data;

[0077] Determine the comprehensive difference between each group of fitting verification data and the corresponding data in the verification group, and finally obtain the regression value of the correlation coefficient to obtain the geological transition fitting model;

[0078] Based on the geological transition fitting model, geological transition fitting is performed on a plurality of soil geological data and terrain data containing drop characteristics to generate a geological distribution layer.

[0079] In this embodiment, the steps of geological transition fitting are explained, especially the acquisition of the geological transition fitting model for fitting. In a common geological environment, the intensity change of the corresponding geological type is a transitional change process, that is, when the soil in area b changes to sand and gravel in area c, it is a transitional change process, not a sudden change. Therefore, the transition fitting model can be trained through historical data. Based on the collected data group, interval extraction is performed according to the distribution, and the data group is divided into a training group and a verification group. The training group is used to fit a transition change coefficient of a different address type, and then its rationality is judged through the verification group, thereby obtaining a transition fitting model for transition simulation, and fitting the geological distribution of the evaluation area based on the data collected at the points in the current evaluation area. Here, the data used for training is obtained from areas with the same address type, because when the geological type span is large, the laws of geological change will also be quite different.

[0080] As another preferred embodiment of the present invention, the steps are also included:

[0081] A construction time cost model corresponding to the geological category is obtained based on historical data training, and the construction time cost model is used to characterize the correlation between the time required for unit construction distance and the change of the intensity of the corresponding geological category;

[0082] When performing a path planning calculation for the evaluation area, a cost requirement sequence is established based on the ascending order of the cost requirements;

[0083] Based on the environmental geological distribution data and the construction time cost model, a construction period requirement evaluation is performed on multiple path plans of the cost requirement sequence to generate corresponding time cost requirements.

[0084] In this embodiment, the estimation of time cost is supplemented. Different projects also have construction period restrictions. Therefore, if the line arrangement is unreasonable, the construction period may be extended during construction, affecting the final delivery and use of the project. Different geological types have different unit progress time consumption during construction, so the time cost can be estimated based on this. For example, for sand and gravel areas, fine sand and gravel are more convenient for construction, but as the stone content and volume increase, the construction difficulty will gradually increase. Therefore, for the same paving distance, the time spent will also increase accordingly.

[0085] like Figure 3 As shown, as another preferred embodiment of the present invention, the step of obtaining the starting and ending points of the pipeline layout, performing path planning calculation on the evaluation area based on the environmental construction costs of several unit areas, and obtaining the cost-optimal path specifically includes:

[0086] S41, establishing an evaluation matrix of the evaluation area based on the unit area, wherein the evaluation matrix includes eight path directions associated with adjacent evaluation matrices;

[0087] S42, calculating the estimated distance from the current node to the target node based on the Euclidean distance, using a priority queue to store the path and the corresponding cost as an open list;

[0088] S43, executing a loop program, extracting the minimum cost node based on the open list, and determining the end point. If the current minimum cost node is the end point, the search is terminated and the optimal path is selected.

[0089] In this embodiment, in the aforementioned embodiment, the evaluation area has been divided into 10*10 unit area grids, and the cost of each small grid has been estimated. Therefore, the final cost-optimal path judgment step is to determine the planning problem of the path with the minimum weight (sum of costs) between points AB, and each grid can be connected to the next grid in eight directions: front, back, left, right, and diagonal. This embodiment uses the A* algorithm to determine the optimal path. The algorithm is a heuristic algorithm that uses a heuristic function to estimate the distance from the current node to the target node, so that the path can be guided when the minimum cost path is searched first, so as to quickly converge to the target.

[0090] like Figure 4 As shown, the present invention also provides a pipeline layout management system based on data analysis, which includes:
