Abstract: In order to solve the increasingly prominent contradiction between the operation of the maintenance vehicle parking and the demand for transport organization, the auxiliary management system of national railway freight car maintenance vehicle was proposed. The system adopted the B/S mode, used SSH as the MVC development framework, Oracle11g as the production database, faced the users of dispatching, vehicle and vehicle department, solved the problem that multiple departments could not share the data of maintenance vehicle, and did not have the unified dispatching of vehicles to be repaired by the superior dispatching department, implemented "win win" in vehicle maintenance efficiency and transport efficiency.
