Train control method and system

Abstract

The invention provides a train control method and system. The method comprises the steps that an ATS sends received severe weather mode range information and a severe weather mode setting command to a DSU; after the DSU verifies the severe weather mode range information, the DSU forwards the severe weather mode setting command to a ZC; and after receiving the severe weather mode setting command, the ZC sets an area corresponding to the severe weather mode range information as a first severe weather area, and controls the train to enter the severe weather mode when the train enters the first severe weather area. The system executes the method. Safety setting of driving in the severe weather mode is completed in a one-time confirmation mode, the workload of dispatchers is reduced, and the operation efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of rail transportation, in particular to a train control method and system. Background technique [0002] Due to the weather or environmental factors causing the track adhesion coefficient to be too small, the wheels of the train will slip when running at high speed in this area. The continuous slippage will cause the train's speed measurement to be invalid and degraded, which will affect the operation efficiency and may bring unknown safety hazards to the operation. Therefore, dispatchers need to set severe weather commands to let the communication-based automatic train control system CBTC-class trains enter the severe weather mode control after they stop. When the existing operating lines are set to the severe weather mode, most of them are set to the severe weather mode of the whole line, which causes the control range to be too large, and the operation efficiency of the whole line is too low.

Problems solved by technology

[0002] Due to weather or environmental factors, the track adhesion coefficient is too small, and the wheels will slip when the train runs at high speed in this area. The continuous slip will cause the train speed measurement to be invalid and degrade the operation, which will affect the operation efficiency and may bring unknown safety hazards to the operation. Therefore, the dispatcher needs to set a severe weather command, so that the communication-based automatic train control system CBTC-level train will enter the severe weather mode control after it stops.

When the severe weather mode is set on the existing operating lines, most of them are set to the severe weather mode of the whole line, resulting in too large control range, which leads to the low operation efficiency of the whole line
