[0055] In the related art, in order to accurately and efficiently install urban underground pipelines, it is usually necessary to construct a three-dimensional model of the urban underground pipelines and complete the installation of the underground pipelines according to the three-dimensional model. In the prior art, a two-dimensional pipeline design drawing is usually used to generate a three-dimensional model. This method is cumbersome and complicated, the model construction efficiency is low, and it is easy to have inaccurate model parameters, resulting in poor accuracy.

[0056] In order to solve the above problems, the present disclosure provides a forward design method and device for an urban underground pipeline model, which obtains pipeline parameter information and pipeline layout condition data of a target pipeline underground in the city; generates a three-dimensional pipeline path of the target pipeline according to the layout information, elevation information and pipeline layout condition data; generates an initial three-dimensional pipeline model according to pipeline type parameters and the three-dimensional pipeline path; obtains a first model associated with the target pipeline according to the position area coordinates; determines the conflict points of the initial three-dimensional pipeline model based on the first model; and performs avoidance replanning processing on the initial three-dimensional pipeline model based on the conflict points to obtain a three-dimensional pipeline model. The three-dimensional pipeline model is directly generated through pipeline parameter information and pipeline layout condition data, and conflict avoidance can be performed on models in the neighborhood, thereby improving the convenience and accuracy of generating an urban underground pipeline model.

[0057] Figure 1 is a flow chart of a forward design method for an urban underground pipeline model according to an exemplary embodiment. Figure 1 As shown, it should be noted that the forward design method of the urban underground pipeline model of the embodiment of the present disclosure is applied to the forward design device of the urban underground pipeline model. Figure 1 As shown, the method may include the following steps:

[0058] Step 101, obtaining pipeline parameter information of a target pipeline underground in a city and the pipeline layout condition data.

[0059] The pipeline parameter information includes the layout information, elevation information, pipeline type parameters and location area coordinates of the target pipeline.

[0060] In some embodiments of the present disclosure, the pipeline layout condition data may include various standards, specifications and guidelines related to pipeline planning, such as urban underground pipeline forward design standards, construction specifications, project delivery requirements, safety and environmental protection standards.

[0061] Step 102: Generate a three-dimensional pipeline path of the target pipeline according to the layout information, elevation information and the pipeline layout condition data.

[0062] In one embodiment, an A* algorithm may be used to determine constraint conditions based on the layout information, elevation information, and pipeline layout condition data to generate a three-dimensional pipeline path for the target pipeline.

[0063] Step 103: Generate an initial three-dimensional pipeline model according to the pipeline type parameters and the three-dimensional pipeline path.

[0064] It is understandable that after obtaining the three-dimensional pipeline path, it is necessary to determine the pipeline type, pipeline diameter and other attribute information according to the preset pipeline type parameters, and generate an initial three-dimensional pipeline model according to the pipeline type parameters and the three-dimensional pipeline path.

[0065] In one embodiment, a cross-sectional graphic of a three-dimensional pipeline model may be generated at the end of a three-dimensional pipeline path according to pipeline type parameters, and the cross-sectional graphic may be stretched along the corresponding three-dimensional pipeline path to obtain a three-dimensional pipeline model.

[0066] Step 104: acquiring a first model associated with the target pipeline according to the location area coordinates.

[0067] The first model is a model within the location area coordinates or within a preset distance from the location area coordinates.

[0068] It is understandable that since pipelines are installed underground in cities, and there are already many complex pipelines or equipment both above and below the ground in urban areas, these factors need to be fully considered in the process of generating a three-dimensional pipeline model to avoid the problem of the three-dimensional pipeline model being incompatible with the actual site.

[0069] Therefore, the target area range can be determined according to the location area coordinates and the preset distance, that is, the target area range is expanded outward on the basis of the location area coordinates to obtain the target area range and acquire at least one first model within the target area range.

[0070] In one embodiment, the first model may be generated according to the parameters of the physical components within the target area, or the first model may be obtained by matching the corresponding model in a preset model library according to the parameters.

[0071] Step 105: determining conflict points of the initial three-dimensional pipeline model based on the first model.

[0072] In some embodiments of the present disclosure, the three-dimensional pipeline model includes multiple types of pipeline sub-models, and step 105 may specifically include the following steps:

[0073] Performing conflict detection on the plurality of types of pipeline sub-models and the first model according to the pipeline layout condition data to obtain the conflict point;

[0074] The step of performing avoidance replanning processing on the initial three-dimensional pipeline model based on the conflict point to obtain a three-dimensional pipeline model includes:

[0075] When it is determined that all models associated with the conflict point are the first model, or include the first model and the pipeline sub-model, determining that the type of the conflict point is an external interference conflict point, and performing avoidance processing on the initial three-dimensional pipeline model based on the conflict point to obtain a three-dimensional pipeline model;

[0076] When it is determined that all models associated with the conflict point are the pipeline sub-models, the type of the conflict point is determined to be an internal interference conflict point, and the initial three-dimensional pipeline model is replanned based on the conflict point to obtain a three-dimensional pipeline model.

[0077] It should be noted that if the models that conflict with this initial 3D pipeline model are all first models, that is, external models, such as other urban underground equipment, pipelines, etc., they need to be avoided. Only when they cannot be avoided will the physical components corresponding to the first model be considered for migration or removal. If there is a conflict within this initial 3D pipeline model, re-planning can be used to eliminate the conflict point.

[0078] Therefore, in one embodiment, the initial three-dimensional model may be processed accordingly according to the model type associated with the light-coated point, so as to eliminate the conflict.

[0079] In some other embodiments of the present disclosure, step 105 may specifically include the following steps:

[0080] determining a first type of said first model;

[0081] In the case where the first type meets a preset condition, determining a safety distance between the first model and the initial three-dimensional pipeline model according to the first type;

[0082] Generate a bounding box of the first model according to the safety distance;

[0083] Performing conflict detection on the bounding box and the initial three-dimensional pipeline model to obtain a detection result;

[0084] When the detection result indicates that there is a conflict, the bounding box is determined as the conflict point.

[0085] It is understandable that in some cases, the first model cannot have direct contact with the initial three-dimensional pipeline model, while in other cases, the first model needs to maintain a certain distance from the initial three-dimensional pipeline model. It is necessary to determine which specific situation it is based on the type of the first model.

[0086] Therefore, when it is determined that the first type of the first model satisfies the preset conditions, that is, when the first model needs to maintain a certain distance from the initial three-dimensional pipeline model, the safety distance between the first model and the initial three-dimensional pipeline model is determined according to the first type, and a bounding box of the first model is generated according to the safety distance. A conflict detection is performed on the bounding box and the initial three-dimensional pipeline model to obtain a detection result. When the detection result shows that there is a conflict, the bounding box is determined as the conflict point.

[0087] Step 106: Perform avoidance replanning processing on the initial three-dimensional pipeline model based on the conflict point to obtain a three-dimensional pipeline model.

[0088] In some embodiments of the present disclosure, step 106 may specifically include the following steps:

[0089] Obtaining constraints associated with the target pipeline; the constraints are obtained by structurally processing normative documents associated with pipeline layout;

[0090] Based on the constraint conditions and the conflict points, the initial three-dimensional pipeline model is subjected to avoidance replanning processing to obtain a three-dimensional pipeline model.

[0091] As an example of a possible implementation, the pipeline layout condition data may be text data, and regular expressions may be used to regularize the text data to obtain structured constraint conditions, namely, pipeline layout conditions.

[0092] In some embodiments of the present disclosure, after step 106, the following steps may be specifically included:

[0093] Acquiring parameter update data of the target pipeline in real time;

[0094] Performing an updating process on the three-dimensional pipeline model based on the parameter updating data to obtain an updated initial three-dimensional pipeline model;

[0095] Evaluating the updated initial three-dimensional pipeline model based on the pipeline layout conditions and preset evaluation indicators to obtain an evaluation result;

[0096] When the evaluation result does not meet the preset conditions, a warning message is output.

[0097] It is understandable that during the installation of urban underground pipelines, unexpected situations may occur or the requirements for pipeline design may change. At this time, the 3D pipeline model needs to be adjusted according to the actual situation. However, due to the suddenness and contingency of such adjustments, the adjusted parameters may not meet the constraints.

[0098] In one embodiment, the three-dimensional pipeline model is updated based on the parameter update data to obtain an updated initial three-dimensional pipeline model, and the updated initial three-dimensional pipeline model is evaluated based on the pipeline layout conditions and preset evaluation indicators to obtain an evaluation result. If the evaluation result does not meet the preset conditions, a warning message is output to prompt the staff to adjust the parameter update data that does not meet the preset conditions.

[0099] In some embodiments of the present disclosure, the parameter information also includes text element information of text annotation. After step 106, the following steps may be specifically included:

[0100] Binding the text element information of the text annotation class to the corresponding position of the initial three-dimensional pipeline model;

[0101] In response to monitoring that the user's cursor moves to the corresponding position, the text element information of the text annotation class is displayed.

[0102] In one embodiment, the preset text annotation type text element information can be used to monitor the user's cursor movement position. When the user's cursor is detected to move to the corresponding position, the text annotation type text element information is displayed to facilitate the user to check relevant information.

[0103] According to the forward design method of the urban underground pipeline model proposed in the embodiment of the present disclosure, the pipeline parameter information and pipeline layout condition data of the target pipeline in the city are obtained; the three-dimensional pipeline path of the target pipeline is generated according to the layout information, elevation information and pipeline layout condition data; the initial three-dimensional pipeline model is generated according to the pipeline type parameters and the three-dimensional pipeline path; the first model associated with the target pipeline is obtained according to the position area coordinates; the conflict points of the initial three-dimensional pipeline model are determined based on the first model; and the initial three-dimensional pipeline model is subjected to avoidance and replanning processing based on the conflict points to obtain the three-dimensional pipeline model. The three-dimensional pipeline model is directly generated through the pipeline parameter information and pipeline layout condition data, and conflict avoidance can be performed on the models in the neighborhood, thereby improving the convenience and accuracy of generating the urban underground pipeline model.
