At present, the flow chart is stored in the form of unstructured DWG, PDF electronic files, or paper, and its utilization/management has the following problems:

1) The elements in the drawing can only be browsed inefficiently, and cannot be quickly searched and located and cannot be jumped to the drawing. In order to solve this problem, the code/coordinate correspondence in the flow chart was extracted manually for query, but it was stopped because the update was not timely and the consistency with the drawing could not be ensured;
