Train control system capable of enabling C3 high-speed rail motor train unit to run circuitously by utilizing common speed line

Abstract

A train control system capable of enabling a C3 high-speed rail motor train unit to run circuitously through a common speed line adopts a station data server to achieve centralized management of ground line data stations, and the train-mounted train selects wireless message information through serial numbers of ground passive transponders, so that later line data maintenance is facilitated. A wireless message is sent by adopting a 400MHz frequency special for a railway, four frequency points are used in total, the bandwidth is 12.5 kHz, the same-frequency interference between different radio stations is prevented, the operation requirement that the operation speed is below 200km / h is met, and the transportation organization is flexible. The temporary speed limit server has the management functions of temporary speed limit command storage, verification, deletion, splitting, setting, cancelling and the like, and can set temporary speed limit in any range in an interval or a station to meet the requirements of various operation scenes.

Description

technical field [0001] The present invention relates to train control systems. Background technique [0002] Sudden failure of high-speed rail lines and equipment may lead to interruption of traffic, which will seriously affect the order of high-speed rail transportation. After investigation, it is found that most of my country's main high-speed rail lines and surrounding normal-speed railways have circuitous conditions. High-speed lines run roundabouts to reduce the impact of high-speed rail infrastructure failures or emergencies on the order of high-speed rail transportation. [0003] The EMU train with C2 level ATP on-board equipment for train control is equipped with train operation monitoring equipment (LKJ) as a backup, so it can use LKJ equipment to monitor and run in accordance with CTCS-0 standard when running on a normal speed line. When the EMU train with C3-level ATP on-board train control equipment is running on the normal speed line according to the current con...

AI Technical Summary

Problems solved by technology

[0010] The use of CTCS-1 train control system to realize the operation of the C3 high-speed rail EMU circuitous normal speed line needs to cover the entire line of the GSM-R network, and there are many stations without GSM-R network coverage on the existing normal speed line, fully covering the GSM-R network investment The cost is high, the transformation of existing lines is large, and it is difficult to realize

[0011] As a technical reserve, the C1 system has only completed the simulation test in the laboratory and has not been verified on site
