Scope

Main technical content: In recent years, the urban rail transit industry is moving towards intelligent and green development, playing an increasingly important role in alleviating the pressure of public transportation in first- and second-tier cities. Therefore, urban rail transit systems need to achieve higher levels in terms of interconnectivity, safety, speed, and comfort. At present, many cities in China have proposed plans to adopt advanced, highly reliable, and safe fully automatic operation systems to meet these requirements. A fully automatic operation system is a train operation mode in which the tasks performed by train drivers are completely replaced by an automated and highly centralized control system. The train control system based on vehicle-to-vehicle communication (TACS) has become the development direction of the next-generation metro train control signaling system. TACS, short for Train Autonomous Circumambulate System, is a vehicle-to-vehicle communication-based autonomous train operation system that enables information exchange between trains through wireless communication, allowing direct access to the location, speed, and route status of other trains. The GoA (Going Autonomous) level of train operation is divided into five grades. The fully automatic operation system includes GoA3 and GoA4 levels, with GoA4 representing fully unattended automatic train operation. TACS enables autonomous resource management and active spacing protection based on operational plans and real-time positioning, making it a key rail transit control technology under global research. Compared with traditional CBTC (Communication-Based Train Control) systems, TACS-equipped lines offer shorter running intervals, higher capacity, and greater flexibility. TACS empowers trains with their own "brain" and "vision," enabling active diverting, automatic protection, adaptive adjustment, and fully autonomous driving, serving as a crucial pathway for developing green, smart,
