The invention discloses an integrated automation system of a metro vehicle base. The system includes a production operation task integrated management unit, a station integrated information processing unit, a train access management unit, a production operation site handheld terminal unit, a production operation energy-saving management unit and a production process site safety control unit. The system solves the problems that metro vehicle base production operation process management is extensive, operation links are disjointed, the automation degree of operation execution is low, the operation execution lacks of safe management and control, operation site information is difficult to obtain, and the energy consumption of operation is larger. The metro vehicle base production management informationization and automation levels are improved, the production operation efficiency is improved, the production operation safety risk is reduced, the energy consumption of operation is reduced, and a safety and quality guarantee is provided for the metro main line high-level traffic safety and the high-level passenger service.
