The invention belongs to the technical field of
engineering drawing management, and discloses a
railway signal drawing
analysis method,
system and device, and the method comprises the steps: carrying out the preprocessing of all
signal drawings of a target
station, carrying out the drawing frame recognition and forward mapping of obtained first data, and obtaining a first data frame; performing table recognition on the obtained second data to obtain table structure data; identifying characters in the second data by utilizing a plurality of character identification technologies, correspondingly obtaining a plurality of
original data, then performing fusion operation to obtain table character data, and performing
reverse mapping after merging the table character data with the table structure data; extracting terminal relation data according to the obtained third data to construct an equipment relation tree; after the name of the target element is received, node terminal relation data of the target element is retrieved in the equipment relation tree, a matched target graph is searched in the second data and then is drawn with the node terminal relation data, an equipment
relation graph is obtained, efficient query is achieved, and all associated drawings of the
signal equipment are visually displayed in a
graphic mode.
