System Introduction
TACS is a new type ATC system that is centered on train and transforms train operation mode from automation to autonomy, with the adoption of resource management concept, the basis of train-to-train communication and the feature of signaling system and vehicle deep integration.
System Architecture
Train Autonomous Circumambulation System(TACS) mainly includes the Automatic Train Supervision (ATS), On-Board Controller (OBC), Object Controller (OC), Data Communication System (DCS), and Intelligent Operation and Maintenance System (IOM). It integrates the trackside interlocking equipment and zone control equipment in the traditional CBTC into the on-board controller, and realizes the functions of train Self-routing and train Self-protection through data communication between trains.
System characteristics and advantages
- Safer and more reliable: The availability is increased from 99.99% to 99.9996%. Distributed design is adopted to avoid the multi-train degradation caused by CBTC wayside equipment failure, provide more effective system guarantee and significantly improve operation safety.
- More intelligent: Self-routing, Self-protection and Self-regulation, to realize the automous train operation.
- More efficient and flexible: The turn-back headway increased by 21%. In case of fire, flooding and other emergencies, TACS trains can complete the turn-back within 12 seconds, and quickly return to the safe area.
- More Cost-effective: The TACS system simplifies the equipment, reduces the construction investment by 10% and reduces the system commissioning time by 30%; and greatly reduces the maintenance times and intensity, reducing the whole life cycle cost by 20%.
- Easier interconnection and interoperability: The number of interfaces has been reduced from 6 to 4, making interconnection and interoperability easier to achieve. The renovation of old lines saves 30% of the time.
