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 supports and hangers; D, outputting proofreading advice; E, generating a proofreading file. The intelligent proofreading method and system has the advantages that the
engineering data of the three-dimensional pipelines and the supports and hangers can be automatically intelligently proofread, the efficiency of the digital design and the proofreading efficiency of the three-dimensional models are increased greatly, and the careless omission of artificial proofreading is evidently reduced even avoided.
