For example, the steps described in the present disclosure can be executed in parallel, sequentially or in different orders, as long as the desired results of the technical solutions disclosed in the present disclosure can be achieved, which are not limited herein.

[0055] In the related art, in order to accurately and efficiently install city underground pipelines, it is usually necessary to construct a three-dimensional model of the city underground pipelines, and the installation of the underground pipelines is completed 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 way is tedious and complex to operate, the construction efficiency of the model is low, and the model parameters are prone to inaccuracy, resulting in poor accuracy.

[0056] To solve the above problems, the disclosure provides a forward design method and device of an urban underground pipeline model. The pipeline parameter information and pipeline arrangement condition data of a target pipeline under the city are obtained. A three-dimensional pipeline path of the target pipeline is generated according to the arrangement information, elevation information and pipeline arrangement condition data. An initial three-dimensional pipeline model is generated according to the pipeline type parameter and the three-dimensional pipeline path. A 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. The initial three-dimensional pipeline model is re-planned to avoid conflicts based on the conflict points, and a three-dimensional pipeline model is obtained. The three-dimensional pipeline model is directly generated by the pipeline parameter information and the pipeline arrangement condition data, and the model in the neighborhood can be avoided for conflict. The convenience and accuracy of generating the urban underground pipeline model are improved.

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

[0058] Step 101, obtaining the pipeline parameter information and the pipeline arrangement condition data of a target pipeline under the city.

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

[0060] In some embodiments of the disclosure, the pipeline arrangement condition data can include various standards, specifications and guiding principles related to pipeline planning. For example, urban underground pipeline forward design standards, construction specifications, project delivery requirements, safety and environmental protection standards.

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

[0062] In one embodiment, A* algorithm can be used to determine the constraint conditions according to the arrangement information, elevation information and pipeline arrangement condition data, and generate a three-dimensional pipeline path of the target pipeline.

[0063] Step 103, generating an initial three-dimensional pipeline model according to the pipeline type parameter and the three-dimensional pipeline path.

[0064] It can be understood that after obtaining the three-dimensional pipeline path, it is necessary to determine attribute information such as pipeline type and pipeline diameter according to a preset pipeline type parameter, and generate an initial three-dimensional pipeline model according to the pipeline type parameter and the three-dimensional pipeline path.

[0065] In one embodiment, a cross-sectional pattern of the three-dimensional pipeline model can be generated at an end of the three-dimensional pipeline path according to the pipeline type parameter, and the cross-sectional pattern is stretched along the corresponding three-dimensional pipeline path to obtain the three-dimensional pipeline model.

[0066] In step 104, a first model associated with the target pipeline is obtained according to the position area coordinate.

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

[0068] It can be understood that since the pipeline is installed underground in the city, the ground and underground of the city area have been configured with many complex pipelines or equipment, and therefore, these factors need to be fully considered in the process of generating the three-dimensional pipeline model to avoid the problem that the three-dimensional pipeline model cannot be adapted to the actual site.

[0069] Therefore, the target area range can be determined according to the position area coordinate and the preset distance, that is, the target area range is expanded outward on the basis of the position area coordinate to obtain the target area range, and at least one first model in the target area range is obtained.

[0070] In one embodiment, the first model can be generated according to the parameters of the entity member in the target area range, or the corresponding model is matched in a preset model library according to the parameters to obtain the first model.

[0071] In step 105, a conflict point of the initial three-dimensional pipeline model is determined based on the first model.

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

[0073] The pipeline sub-models of the multiple types and the first model are subjected to conflict detection according to the pipeline arrangement condition data to obtain the conflict point;

[0074] The initial three-dimensional pipeline model is subjected to avoidance re-planning processing based on the conflict point to obtain a three-dimensional pipeline model, including:

[0075] In a case where it is determined that all the models associated with the conflict point are the first model or include the first model and the pipeline sub-model, it is determined that the type of the conflict point is an external interference conflict point, and the initial three-dimensional pipeline model is processed for avoidance based on the conflict point, to obtain a three-dimensional pipeline model.

[0076] In a case where it is determined that all the models associated with the conflict point are the pipeline sub-model, it is determined that the type of the conflict point is an internal interference conflict point, and the initial three-dimensional pipeline model is processed for re-planning based on the conflict point, to obtain a three-dimensional pipeline model.

[0077] It should be noted that, if all the models in conflict with the initial three-dimensional pipeline model are the first model, i.e., external models, such as other urban underground equipment and pipelines, avoidance needs to be performed thereon, and in a case where avoidance is impossible, migration or removal of the entity component corresponding to the first model needs to be considered. If there is a conflict within the initial three-dimensional pipeline model, a re-planning manner can be used to eliminate the conflict point.

[0078] Therefore, in one embodiment, the initial three-dimensional model can be processed according to the model type associated with the light coating point to eliminate the conflict.

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

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

[0081] in a 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] generating 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] in a case where the detection result is that there is a conflict, determining the bounding box as the conflict point.

[0085] It can be understood that, in some cases, the first model cannot be in direct contact with the initial three-dimensional pipeline model, and in some other cases, the first model needs to maintain a certain distance from the initial three-dimensional pipeline model, and the specific case needs to be determined according to the type of the first model.

[0086] Therefore, in a case where the first type of the first model meets a preset condition, i.e., the first model needs to maintain a certain distance from the initial three-dimensional pipeline model, a safety distance between the first model and the initial three-dimensional pipeline model is determined according to the first type, a bounding box of the first model is generated according to the safety distance, and a conflict detection is performed on the bounding box and the initial three-dimensional pipeline model to obtain a detection result. In a case where the detection result is that there is a conflict, the bounding box is determined as the conflict point.

[0087] In step 106, the initial three-dimensional pipeline model is re-planned to avoid the conflict point to obtain a three-dimensional pipeline model.

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

[0089] The constraint condition associated with the target pipeline is obtained by structuring a normative file associated with the pipeline arrangement.

[0090] The initial three-dimensional pipeline model is re-planned to avoid the conflict point based on the constraint condition and the conflict point to obtain a three-dimensional pipeline model.

[0091] As an example of a possible implementation, the pipeline arrangement condition data can be text data, and the text data can be regularized by using a regular expression to obtain a structured constraint condition, i.e., a pipeline arrangement condition.

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

[0093] The parameter update data of the target pipeline is obtained in real time.

[0094] The three-dimensional pipeline model is updated based on the parameter update data to obtain an updated initial three-dimensional pipeline model.

[0095] The updated initial three-dimensional pipeline model is evaluated based on the pipeline arrangement condition and a preset evaluation index to obtain an evaluation result.

[0096] In a case where the evaluation result does not meet a preset condition, a warning information is output.

[0097] It can be understood that in the process of installing urban underground pipelines, unexpected situations can occur, or the demand for pipeline design can change, and at this time, the three-dimensional pipeline model needs to be adjusted according to the actual situation. However, due to the suddenness and contingency of such adjustment, the adjusted parameters can not meet the constraint condition.

[0098] In one embodiment, the three-dimensional pipeline model is updated according to the parameter update data to obtain an updated initial three-dimensional pipeline model, the updated initial three-dimensional pipeline model is evaluated based on the pipeline arrangement condition and a preset evaluation index to obtain an evaluation result, and in a case where the evaluation result does not satisfy a preset condition, a warning information is output to prompt a staff to adjust the parameter update data that does not satisfy the preset condition.

[0099] In some embodiments of the present disclosure, the parameter information further includes text annotation type text element information, and after step 106, the method can further include the following steps:

[0100] The text annotation type text element information is bound to a corresponding position of the initial three-dimensional pipeline model.

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

[0102] In one embodiment, the preset text annotation type text element information can be listened to the cursor movement position of the user, and when it is monitored that the cursor of the user moves to the corresponding position, the text annotation type text element information is displayed to facilitate the user to check the relevant information.

[0103] According to the forward design method of the urban underground pipeline model provided in the embodiments of the present disclosure, pipeline parameter information and pipeline arrangement condition data of a target pipeline in an urban underground are acquired, a three-dimensional pipeline path of the target pipeline is generated according to arrangement information, elevation information and the pipeline arrangement condition data, an initial three-dimensional pipeline model is generated according to pipeline type parameters and the three-dimensional pipeline path, a first model associated with the target pipeline is acquired according to position region coordinates, a conflict point of the initial three-dimensional pipeline model is determined based on the first model, and the initial three-dimensional pipeline model is re-planned to avoid the conflict point to obtain a three-dimensional pipeline model. The three-dimensional pipeline model is directly generated through the pipeline parameter information and the pipeline arrangement condition data, and the model in a neighborhood can be avoided for conflict, which improves the convenience and accuracy of generating the urban underground pipeline model.
