Study on the mechanism of high-speed train following operation control

The mechanism of high-speed train following operation control was studied keeping in mind the moving and length changing characters of train spacing in the railway moving automatic block system. We analyzed the behavioral adjustment problems of high-speed trains in the process of train following operation to lay down the integrated optimal indexes for dynamic evaluation of the behavioral adjustment, and then used the Petri network to give the formal description of train operation states, and the causes and process of behavioral adjustments. The control model was established to deal with the behavioral adjustments of the high-speed train in the process of its following operation, and the comprehensive evaluation method of train behavior as well as the control strategy algorithm and specific implementation steps were given. The simulations results show that the method can give help to dynamic control of train spacing and effective realization of train operation with safety, efficiency and stability.
