5. The train automatic overhaul control system of claim 1, wherein the intelligent overhaul subsystem comprises a train overhaul console unit, and the train overhaul console unit is configured to perform automatic fault judgment on a high-definition collected image transmitted to the control center in real time by the CBTC network based on an image recognition algorithm after receiving an overhaul instruction, automatically feed back fault judgment information to an overhaul personnel for verification, and generate the fault maintenance schedule.
6. The control method of the automatic train maintenance control system according to any one of claims 1 to 5, comprising:
acquiring the collected data of each subsystem;
performing local analysis based on the acquired data to generate alarm level information;
the preset middle-low level alarm information in the alarm level information is not reported to a control center and is reserved to the local for maintenance as data;
reporting preset high-level alarm information in the alarm level information to the control center through a CBTC (communication based train control) system, and carrying out maintenance judgment;
if the non-stop overhaul is judged and the fault is eliminated, the non-stop overhaul is executed;
otherwise, the control center generates a maintenance plan, reports the maintenance plan to the train stop station, formulates a maintenance plan and carries out train maintenance based on the maintenance plan.
