Intelligent proofreading method and system for digital design of power plant

The invention relates to an intelligent proofreading method and system for the digital design of a power plant. The method includes the steps of A, collecting information, to be more specific, scanning engineering drawings including PID system diagrams and manufacturer data into graphical mapping diagrams and data text files; B, importing data, to be more specific, extracting the three-dimensional model information of to-be-proofread pipelines and supports and hangers, and classifying and collecting the extracted information and the data generated in the step A; C1, proofreading design specifications; C2, proofreading the PID system diagrams and the three-dimensional model topological relation; C3, calculating, matching and proofreading three-dimensional model and pipeline stress; C4, matching and proofreading the manufacturer data; C5, proofreading three-dimensional support and hanger models and the support and hanger original data; C6, performing collision check proofreading on the pipelines and the support
