During the hydraulic system design process, the flow requirements of system users will be iteratively updated as the design gradually deepens. Different functional pipelines have different limiting flow rates. The change in flow will select different pipeline specifications according to the flow rate limit. After the pipelines are intersected, the change in flow will also affect the change in pipeline specifications. The hydraulic system uses multiple independent energy systems, and the total number of pipelines is thousands. The setting of pipeline specification attributes will consume a lot of human resources and is prone to errors. Summary of the invention
