Railway vehicle management system based on big data

The invention discloses a rail vehicle management system based on big data, belongs to the field of rail vehicle management, relates to a big data technology, and comprises a vehicle acceptance module, a standard making module, an execution module, an analysis management module, a vehicle management module, a standard updating module, a data storage module, a timing module and a feedback module. Through cooperation of the modules, maintenance plan adjustment is carried out according to a maintenance result, generation of many sudden faults is avoided, some precision prediction processes are provided at the same time, effective prediction is carried out on maintenance items with precision requirements before precision exceeds a range, and the maintenance efficiency is improved. And before the precision exceeds the range, parts are replaced to prevent the precision from exceeding the range to cause faults, and finally unnecessary investment of manpower, material resources and financial resources is reduced. 本发明
