[0055] S1 pipe network data collection:

[0056] The pipeline path information collection module is used to collect pipeline path information, including pipeline and well type, name, coordinates, temperature and humidity, and flow direction information. Pipeline and well types include water supply, sewage, rainwater pipelines and wells; the pipeline information collection module is used to collect current pipeline information, including the size, flow rate of pipelines and wells, and gas composition and content in the wells; the city information collection module is used to collect the three-dimensional map model information of the city where the current pipeline network is located, including road information, water type information, water source location information, and sewage purification location information in the three-dimensional map model;

[0057] S2 Pipeline Network 3D Model Construction and Integration:

[0058] After the information identification and classification module identifies and classifies the information collected by the pipe network information collection system, the pipe network model construction unit constructs a three-dimensional pipe network model according to the information collected by the pipe network information collection system, which includes the construction of water supply pipe models, sewage pipe models, rainwater pipe models and pipe well models; then the pipe network model adjustment unit adjusts the content of the pipe network three-dimensional model, which includes adjusting the constructed water supply pipe model, sewage pipe model, rainwater pipe model and pipe well model; the pipe network model fusion unit fuses the constructed three-dimensional pipe network model, which includes fusing the water supply pipe model, sewage pipe model, rainwater pipe model and pipe well model, and integrates them into an integrated model.

After the expansion, the fusion is carried out with the purpose of integrating the water supply pipe, sewage pipe and rainwater pipe needs, and the pipes at the current position are repaired and adjusted;

[0059] Thereafter, the block division identification unit divides the three-dimensional pipe network model into blocks according to the content of the block instruction information, wherein the block instruction includes a block division instruction and a block adjustment instruction, using the block establishment unit, and divides the block size and level according to the park type, population, and water consumption information of the three-dimensional urban map model. At the same time, the block adjustment unit is used to adjust the content of the blocks divided by the three-dimensional pipe network model;

At the same time, when the gas flow rate and the concentration of harmful gases and explosive gases in the well reach the set value, it indicates that suffocation, poisoning, flammability and explosion are likely to occur in this well section, and the harmful gases in the well need to be cleared and unblocked in time;

[0068] At this time, the pipeline network dispatching and control module generates early warning instructions and pipeline network adjustment and repair instructions based on the abnormal data after the pipeline network early warning calculation module. The pipeline network information integration module generates an early warning information list based on the early warning instructions and pipeline network adjustment and repair instructions and combines them with the fused pipeline model. The pipeline network information transmission module transmits the integrated early warning information list to the information interaction system. Finally, the information interaction system transmits the early warning information list to the maintenance management personnel, so that the maintenance management personnel can repair and adjust the pipeline network.

[0069] The design first combines the water supply pipeline, sewage pipeline and rainwater pipeline network with the city's three-dimensional map model to build a pipeline model.
