Design Schemes for FAO Line Intelligent Operation and Control Systems

Objective With the rapid development of technologies in urban rail transit equipment industry and the continuous maturation of their application, the automation level of urban rail transit operations is steadily increasing. FAO (fully automatic operation) systems, featuring high safety, high reliability and high efficiency, are being adopted by many cities. While improving operational safety and efficiency, FAO systems propose new requirements on train dispatchers in areas such as integrated analysis and intelligent decision-making, handling ability of complex operational scenarios, and extended management responsibilities within depots. To assist dispatchers in acquiring information more quickly and making decisions more efficiently, it is necessary to enhance the ATS (automatic train supervision) system with intelligent features. Method Based on the operational needs for secure and intelligent management, smart emergency decision-making, and intelligent emergency response on FAO lines, a design for FAO line IOC (intelligent operation and control) system is proposed, its framework, architecture, and external interfaces are introduced. A detailed analysis is conducted on the performance optimization design of functional modules, including integrated information expansion for train operation, power arm traffic control, fully automated timetable editing, passenger flow analysis and operational evaluation, fault and emergency command, and smart depot collaboration. Result & Conclusion The practical application of the IOC system on Shenzhen Metro Line 16 demonstrates that the intelligent expansion of FAO line ATS system not only improves line operational efficiency, but also significantly enhances the safety and reliability of FAO system. It markedly boosts the level of intelligent operation management, the system adaptability to complex operational environments, and the capacity for rapid response to emergencies.
