The spatial map uses poles and towers as nodes and the conductors between adjacent nodes as adjacent edges. Extract the node features of each tower spatial diagram node.

[0024] S2 combines the tower space map and node characteristics, and generates a set of boundary constraint corridors through the strategic corridor identification method. Within each boundary constraint corridor, a comprehensive cost function is constructed.

[0025] In this embodiment, the step of generating a set of boundary-constrained corridors by combining the tower space map and node features and using the strategic corridor identification method specifically involves: Based on node characteristics, generate a recommended corridor width for each node; Based on node characteristics, the attention weights between nodes are calculated using a graph neural network model, and the strategic importance score of each node is output. By combining strategic importance scores with recommended corridor widths, a set of boundary constraint corridors is obtained.

[0035] It should be noted that the recommended corridor width refers to the lateral width of the corridor space that is recommended to be reserved near the node to ensure line safety, construction feasibility, and safe clearance when crossing obstacles.

[0036] In this embodiment, the step of combining strategic importance scores and recommended corridor widths to filter and obtain a set of boundary constraint corridors is specifically as follows: Nodes with strategic importance scores greater than a preset score threshold are selected to obtain a set of high-value nodes; Based on the recommended corridor width, the neighborhood is expanded with high-value nodes as the center to generate corresponding corridors; The corridors are merged and connected components are extracted to obtain a set of boundary-constrained corridors.

[0037] In this embodiment, nodes with strategic importance scores greater than a preset score threshold are selected to obtain a set of high-value nodes.

[0038] The high-value node set specifically includes:

[0057] S3, based on the boundary-constrained corridor, takes minimizing the comprehensive cost function as the optimization objective and obtains the target tower layout sequence through the coordinated iteration of Monte Carlo tree search and physical-guided neural network.

[0058] In this embodiment, the target tower layout sequence is obtained based on the boundary-constrained corridor, with the optimization objective of minimizing the comprehensive cost function. This is achieved through the collaborative iteration of Monte Carlo tree search and a physically guided neural network. Specifically: Based on the historical boundary constraint corridor, the physical guidance neural network is pre-trained; Within each boundary constraint corridor, a candidate sequence of pole placement is generated through Monte Carlo tree search, and the candidate sequence of pole placement is input into a pre-trained physical guidance neural network to obtain the predicted comprehensive cost; The candidate sequence of tower placement is used as the action space, and the predicted comprehensive cost is used as the state space. Under safety constraints, the predicted comprehensive cost is negatively mapped and used as a reward signal to be fed back to the Monte Carlo tree search process.

[0063] It should be noted that the physical residual term is obtained through automatic differentiation of the differentiable physical equation.

[0064] In this embodiment, under safety constraints, the step of negatively mapping the predicted comprehensive cost as a reward signal and feeding it back to the Monte Carlo tree search process to update the candidate tower layout sequence in the action space to obtain the target tower layout sequence is as follows: The reward signal is input as the return value into the Monte Carlo tree search, and the comprehensive score of the node is calculated using the UCT formula; Based on the cumulative updates of comprehensive scores and node access counts and action access counts, the node strategy of Monte Carlo tree search is continuously optimized; After iterative convergence, a target tower layout sequence that minimizes the predicted comprehensive cost is generated.

[0065] In this embodiment, based on Monte Carlo tree search, starting from the beginning of the search tree, child nodes are selected layer by layer according to the UCT formula until a node that has not been fully expanded is reached, thereby generating a candidate sequence for tower layout. The pre-trained physical guidance neural network is invoked to predict the comprehensive cost corresponding to the extended child nodes, and the predicted comprehensive cost value is obtained. The predicted comprehensive cost value is negatively mapped to obtain the reward signal, which is then used as the approximate return value for the child node. The reward signal is transmitted back layer by layer from the extended child node along the selected path to update the number of visits, the number of action visits, and the average reward value of each node on the path, so as to drive the iterative optimization of the search tree strategy and finally obtain the target tower layout sequence.
