Description

Layout optimization method for underground communication pipeline Technical Field The invention relates to the technical field of pipeline layout, in particular to a layout optimization method for underground communication pipelines. Background With the continuous expansion of urban construction scale, the layout and optimization of communication pipelines in underground space are increasingly becoming important links for ensuring the efficient and stable operation of urban networks. In practical application, the existing underground communication pipeline layout method mostly depends on planning and deployment of existing pipeline resources, so that construction cost is saved and resource utilization efficiency is improved. However, these placement approaches often ignore the actual dependencies and sensitivities of pipeline resources in the network structure, resulting in local resource occupancy, while reasonable, that may cause resource contention and placement imbalance at the overall network topology level, thereby reducing maintainability and scalability of the network. In addition, in the prior art, when modeling and managing a communication pipeline, simple attribute description is usually only carried out on the spatial position and the internal pipe hole state of the pipeline, and deep analysis on the relationship between the occupation of communication pipeline resources and the overall network structure is lacking, so that a critical path and a sensitive resource area in the network topology cannot be effectively identified, and the practical requirements of long-term operation and capacity expansion of the network are difficult to consider in a pipeline layout scheme. Disclosure of Invention In order to overcome the above-mentioned drawbacks of the prior art, embodiments of the present invention provide a layout optimization method for underground communication pipelines. In order to achieve the above purpose, the present invention provides the following technical solutions: a method of layout optimization for a subsurface communication pipeline, the method comprising: After constructing an initial topological structure of the communication pipeline based on the BIM model, determining an association region with a space coupling relation between pipe sections through space association feature analysis of the pipe section resource occupation history; determining a pipe section area range with limited resources in a pipeline network topological structure by analyzing topological constraint association between real-time pipe section occupation data and an association area of a space coupling relation; aiming at the spatial fluctuation characteristics of the node historical flow in the pipe section area, carrying out hierarchical quantitative analysis on the pipe section network transmission sensitivity level, and determining the pipe section resource network transmission sensitivity level; And adopting a topology path searching strategy of the transmission sensitivity level of the embedded pipe section resource network to perform pipeline path calculation, and generating an optimal underground communication pipeline layout scheme. Compared with the prior art, the invention has the beneficial effects that: According to the invention, the spatial distribution characteristics of the pipe section resource occupation history are modeled, and the spatial coupling relation area between the pipe sections is identified by combining the pipeline topological structure, so that the original resource evaluation mode based on single idle state judgment is converted into the comprehensive judgment mode based on spatial association and structure dependence, thereby avoiding improper occupation of pipe section resources in a critical path or with reservation function, and improving the rationality of the layout scheme in the network structure level. According to the invention, the topology constraint association analysis is carried out on the real-time pipe section occupation state and the space coupling relation area, and the pipe section area range with limited resources is positioned, so that the resource use state and the network structure change form a linkage relation, the linkage influence of local resource allocation on the whole network is avoided, and the adaptation capability of the dynamic resource state in the underground communication pipeline layout process is improved. According to the invention, the network transmission sensitivity level division is carried out on the pipe section resources by combining the spatial fluctuation characteristics of the node historical flow, and the sensitivity level constraint is introduced in the path searching process, so that the pipeline layout path is given consideration to the network operation characteristic and the resource use constraint in the planning stage, thereby reducing the risk of occupation of the key path resources and enhancing the continuous oper
