Method for converting COMOS data to PDMS data in pipeline design

The invention relates to a method for converting COMOS data to PDMS data in pipeline design. The method comprises the following steps: traversing a PID plot of COMOS software and generating an endpoint list; B. traversing from a first endpoint of the endpoint list, and generating a pipe system list of the PID plot; C. reading attributes of all elements in the pipe system from a first pipe system in the pipe system list along a logic sequence of pipelines, and storing the read attributes and corresponding attribute values as an intermediate file according to a data format recognizable to the PDMS software; and D. reading, by the PDMS software, the intermediate file, and generating a pipe system list and a three-dimensional data model which correspond to the PID plot. By adopting the method, the data integrated transfer of the three-dimensional modeling from COMOS software to PDMS software is realized, and therefore the design efficiency is greatly improved, errors possibly caused by manually inputting data is
