Fully Automatic Operation (FAO) is the highest level in the automation of urban rail transit train operation. The FAO system is an advanced signalling system based on CBTC,It is mainly composed of Train Integration Automatic System (TIAS), ZC, DSU, CBI, VOBC and DCS. The train operation can be completed automatically by the FAO system without manual attendance, such as train wake up and train sleep. The FAO system solution becomes the best choice for urban rail transit at present. HollySys FAO system is equipped with system functions conforming to global standards, supports interconnection between lines, and can realize DTO or UTO operation according to specific operation requirements of users.
The system adopts Interoperability technology to realize the train running on the same line or across lines that signalling system supplied by different suppliers, and to realize network operation.
The system takes the TIAS as the Core and integrates other related systems such as SCADA, BAS, FAS, PIS and PA based on a unified platform.
On the basis of configuring SIL4 equipment, realize safety operation by adding train obstacle detection system, platform clearance detection system and SPKS.
The system adopts redundancy measures to further improve the reliability, for example, end-toend redundancy design of BTM antenna, speed sensor and accelerometer; ATO equipment adopts redundant design; TCMS network and hard-wired redundancy are adopted for interface with vehicles.
