Automatic adjustment system and method for train plan working diagram

The invention relates to an automatic adjustment system and method for a train plan working diagram. The system comprises a train operation data analysis module, a passenger flow data matching module and a working diagram adjustment module which are connected in sequence, and the train operation data analysis module is connected with the working diagram adjustment module; the train operation data analysis module evaluates the deviation between the actual operation diagram and the planned operation diagram based on ATS historical operation data to obtain an operation diagram evaluation result; the passenger flow data matching module calculates actual passenger flow distribution based on the vehicle-mounted weighing passenger flow data and the AFC passenger flow data and matches the actual passenger flow distribution with an actual working diagram to obtain a passenger flow matching result; and the operation diagram adjustment module optimizes and adjusts the original plan operation diagram according to the ope
