摘要:
在中国城市轨道交通建设规模跃居世界第一的同时，如何探索研发更安全、更灵活、更高效的列车控制系统，满足当下5G（第五代移动通信技术）及智慧城市轨道交通的应用要求，是城市轨道交通未来发展的主要目标之一。对TACS（列车自主运行系统）的原理及系统架构进行阐述，从CI（计算机联锁）的优化、系统运算变量的优势、线路折返效率的提升、系统可靠性和灵活性的提高及在工程实施及改造项目中的优势等方面，将TACS与传统CBTC(基于通信的列车控制)进行对比，并对部分参数进行了实例验证。结果表明：基于车车通信的TACS是目前国际上城市轨道交通应用于载客的列控系统最前沿的技术。
Abstracts:
While the construction scale of urban rail transit in China has ranked first in the world, one of the main goals of urban rail transit development in the future becomes the exploration and development of a safer, more flexible and more efficient train control system, in order to meet the application requirements of 5G (5th generation mobile communication technology) and smart urban rail transit. In this paper, the principle and system architecture of TACS (train autonomous control system) are described and from such aspects as optimization of CI (computer interlock), advantages of system operation variables, improvement of train turn back efficiency, improvement of system reliability and flexibility, as well as advantages in project implementation and reconstruction projects, TACS is compared with traditional CBTC, and some parameters are veri-fied by examples. Results show that TACS based on vehicle-to-vehicle communication is the most advanced technology applied to the passenger train control system in current international urban rail transit.
