Problems solved by technology

[0006] However, the CTCS-2 train control system does not use wireless communication. The ground equipment can only know that the train enters the block zone through the track circuit, but cannot know the exact position of the train. How to shorten the driving interval is a technical problem.

Embodiment Construction

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0022] Embodiments of the present invention provide a method for shortening the interval between trains in a CTCS-2 train control system. The method is based on figure 2 The implementation of the existing CTCS-2 train control system shown in this method does not need to modify the structure of the existing CTCS-2 train control system; figure 2 As shown, the ground equipment is still composed of train control center, track circuit, temporary speed...

Abstract

The invention discloses a method for shortening the running interval of a CTCS‑2 train control system, which includes: calculating the speed at which the train enters the complete current block zone according to the logic occupancy state of the track circuit; The train speed is archived downward, and the archived speed and the number of idle block zones ahead are sent to subsequent trains through the track circuit; the on-board equipment of the follow-up train calculates the vehicle control curve according to the archived speed and the number of idle block zones ahead . This method calculates the passing speed of the train in front through the occupied / idle state of the track circuit, and then sends it to the follow-up train through the track circuit; the follow-up train moves the target point forward according to the number of blocked partitions and the speed of the vehicle in front, thereby shortening the driving interval.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a method for shortening the running interval of a CTCS-2 train control system. Background technique [0002] The Chinese Train Control System (CTCS for short) is the key equipment for my country's high-speed railways to ensure traffic safety. my country's high-speed rail lines below 250km / h adopt CTCS-2 train control system, and those above 250km / h adopt CTCS-3 train control system. [0003] At present, my country's high-speed rail lines adopt quasi-moving blocking technology. The basic tracking principle of CTCS-2 / 3 train control system is as follows: figure 1 As shown, the line is divided into several block zones, and the end of the block zone where the previous train is located is used as the target point for subsequent trains, and a vehicle control curve is calculated according to the braking performance of the train. When the train speed exceeds the vehicle control cu...
