Fully Automatic Operation (FAO) System Solution

System Introduction

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 Communication Based Train Control (CBTC) , It is mainly composed of Train Integration Automatic System (TIAS), Zone Controller (ZC), Data Storage Unit (DSU), Computer Based Interlocking (CBI), Vehicle On-board Controller (VOBC) and Distributed Control System (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 Driverless Train Operation (DTO) or Unattended Train Operation (UTO) operation according to specific operation requirements of users.

Features

Interoperability
- 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.
High Integration
- 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.
Enhance Safety
- On the basis of configuring SIL4 equipment, realize safety operation by adding train obstacle detection system, platform clearance detection system and SPKS.
High Reliability
- 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.

Customer Value

Safe and Reliable

FAO is capable of ensuring the safety of trains, passengers and operators. The multiple redundancy design significantly reduces the system failure rate compared to traditional GoA2 technology, further improving system reliability.
Cost Saving

With less operation staff and maintenance staff required, the cost of manpower is reduced significantly.
Efficient Transportation

The automation level of the system is GoA4, which reduces the response time of driving operation and saves the stop time.
Improve Service Quality

All-round safety design ensures passengers' safety, and high-reliability design reduces transportation interruption or inefficiency caused by system failure, reduces passengers' transfer through interconnection, saves passengers' travel time and improves passengers' travel satisfaction.
