Abstract

The invention discloses a brake control method of an automatic vehicle-mounted train protection system. The running distance of a train can be determined after five stages including a whole service braking traction cutting stage, a whole service braking response building stage, an emergent braking traction cutting stage, an emergent braking response building stage and an emergent braking finish stage, a whole service braking trigger speed can be determined in a retroduction method, and it is guaranteed that when the distance between the position where the train is located and a target speed limiting point and the current running speed of the train trigger whole service braking, emergent braking cannot be triggered.

Description

technical field

[0001] The invention relates to the field of train automatic protection vehicle-mounted systems, in particular to a braking control method of the train automatic protection vehicle-mounted system. Background technique

[0002] According to the existing ATP (Automatic Train Protection, automatic train protection) on-board technology, an EB (Emergency Brake, emergency braking) trigger is obtained from the relationship between the distance from the train to the target speed limit point and the speed of the train. Curve, when the speed of the train at a certain position exceeds the point on the EB trigger curve, the on-board system will trigger emergency braking. Once the emergency braking is triggered, the train will be forced to brake until the train stops.

[0003] In order to reduce the frequency of EB caused by overspeeding of trains and avoid the frequent forced stop of trains due to triggering EB in unnecessary situations, ATP on-board technology further p...
