A Hybrid Framework for High-Performance Modeling of Three-Dimensional Pipe Networks

Abstract

Three-dimensional (3D) pipe network modeling plays an essential part in high performance-based smart city applications. Given that massive 3D pipe networks tend to be difficult to manage and to visualize, we propose in this study a hybrid framework for high-performance modeling of a 3D pipe network, including pipe network data model and high-performance modeling. The pipe network data model is devoted to three-dimensional pipe network construction based on network topology and building information models (BIMs). According to the topological relationships of the pipe point pipelines, the pipe network is decomposed into multiple pipe segment units. The high-performance modeling of 3D pipe network contains a spatial 3D model, the instantiation, adaptive rendering, and combination parallel computing. Spatial 3D model (S3M) is proposed for spatial data transmission, exchange, and visualization of massive and multi-source 3D spatial data. The combination parallel computing framework with GPU and OpenMP was developed to reduce the processing time for pipe networks. The results of the experiments showed that the hybrid framework achieves a high efficiency and the hardware resource occupation is reduced.

“…Li e Cao (2020) por outro lado, verificaram como os dados gerados e utilizados dentro do BIM em conjunto com dados geográficos, como os do SIG, são extremamente interessantes para treinar redes neurais, essas posteriormente podem auxiliar na tomada de decisões "inteligentes" durante todo o ciclo de vida das cidades, obtendo-se como produto a cidade inteligente. Wang et al (2019) criaram uma estrutura híbrida de trabalho, utilizando o BIM e o SIG para desenvolver um modelo 3D das redes de tubulações, essa estrutura facilita tanto no processo da construção de novas redes quanto na manutenção das existentes, como resultado eles conseguiram um framework com grande eficiência e com redução do processamento dos computadores. Shadram et al (2016) apresenta o problema existente na interoperabilidade entre o BIM e os softwares de análise das pegadas ecológicas de certos materiais durante o processo de projeto da construção, para resolução disso foi desenvolvido um framework que apoia as decisões de projeto e permite avaliar a energia incorporada associada ao uso de determinados materiais, tal estrutura foi testada e aprovada em um protótipo obtendo excelentes resultados.…”

Pipeline data calibration for the construction of three-dimensional underground pipeline system

“…The urban underground pipe network can be abstracted as a "pipe point-pipe segment" mathematical model. The existing technology mainly uses the "two points and one line" data structure [3]. At present, the research on urban pipe network is mostly based on the undigraph geometric model or the directed graph geometric model Due to the directionality of the pipeline contents, the analysis based on the geometric model of the directed graph is more accurate [4].…”
