Abstract:
Objective High-speed maglev trains adopt the principle of long stator linear synchronous motors for traction control, requiring coordination between onboard and ground equipment to achieve traction drive. To ensure safe train operation and traffic control, the line must be divided into several operation and control zones to achieve independent segment control of the ground traction lines. Therefore, it is necessary to study the division methods of operation and control zones to optimize their number, thereby satisfying the train headway requirements while reducing engineering construction costs.
Method Taking the train headway as the benchmark for operation and control zoning, the factors influencing the train headway are analyzed; combined with the calculation principle of the minimum headway for high-speed maglev transit systems, the operation and control zone lengths of line sections, intermediate stations, and turnaround stations are calculated and analyzed; the operation and control zoning methods under different minimum headways are proposed respectively, and the operation and control zoning process is summarized.
Result & Conclusion The train headway is influenced by factors of train positioning accuracy, safety distance, station dwell time, and turnout switching time. The operation and control zoning process is: the station type is determined based on station track layout, and the maximum length of the zone is determined by combining the safety distance with power supply limit, dividing the operation and control zones of intermediate stations and terminal turnaround sections in sequence; and then combined with the total length of the section and the minimum number of zones, the dimensions of each zone are determinded. The method can achieve a rational division of operation and control zones for high-speed maglev lines.
