This application relates to the field of alloy steel technology, specifically disclosing an ultra-high strength cast steel base for a high-speed railway permanent magnet traction motor and its preparation method. The ultra-high strength cast steel base for a high-speed railway permanent magnet traction motor is made from a chemical composition comprising the following weight percentages: C 0.15-0.25%, Si 0.2-0.5%, Mn 1.5-2.5%, Cr 0.5-1.25%, Ni 0.3-0.8%, Mo 0.2-0.5%, Al 0.02-0.06%, V 0.05-0.15%, Ti 0.02-0.08%, Nb 0.01-0.05%, P 0.01-0.02%, S 0.005-0.01%, with the balance being Fe. The ultra-high strength cast steel frame for the high-speed railway permanent magnet traction motor of this application achieves ultra-high strength while maintaining excellent plasticity and toughness and extremely high fatigue limit. This allows designers to use thinner and more optimized frame wall thickness while ensuring safety margin, thereby directly achieving the goal of lightweighting and enabling it to cope with the extreme vibration conditions of high-frequency and high-stress cycles of high-speed railway traction motors.

The application discloses a locomotive intelligent operation and maintenance system and method, a storage medium and electronic equipment, and relates to the field of locomotive operation and maintenance.The system comprises a data management platform, a whole vehicle function module and a plurality of business modules, all the modules are independently adapted and deployed in partitions and the running environments are mutually isolated, the data management platform collects and pre-processes multi-source data to obtain standardized data, the whole vehicle function module executes vehicle overall level operation and maintenance management business based on the whole vehicle standardized data distributed by the data management platform, and the business module executes fine operation and maintenance management of corresponding business based on the business standardized data distributed by the data management platform.The application independently deploys all the modules, isolates the running environments, completes independent splitting of the modules, supports parallel collaborative development of multiple professional teams, and shortens the development cycle.The modules do not directly communicate, compatibility problems and implicit faults caused by direct coupling between the modules are eliminated, and the application quality of the system is improved.
