Design and Application of Subway Vehicle Dispatching System Based on Big Data Architecture in FAO Mode

With the development of information and control technology, fully automatic operation system (FAO) has been widely adopted in the construction of new subway lines. Since the main line operating vehicles under FAO mode do not have driver posts, the dispatchers at the control center need to monitor the running status of all trains on the line in real time to ensure the correct operation of the trains. According to the characteristics of FAO mode , this paper designs a train dispatching system based on big data architecture. The system collects status data of train subsystems and processes and analyzes them based on big data framework,which realizes real-time status monitoring of vehicles on the whole line; and provides human-computer interaction interface for remote control, which meets the requirements of metro operation dispatcher for vehicle running status monitoring. The system has been verified by the third party security assessment, and its stability and availability meet the FAO line operation requirements.
