Train tracking method through track circuit/axle counter detection

Abstract

The invention discloses a train tracking method through track circuit / axle counter detection. The train tracking method includes firstly judging whether or not track segments are in a clearing state or an occupied state; secondly adopting a track-occupied train tracking method or track-cleared train tracking method according to the states of the track segments. The train tracking method is suitable to the train tracking method through the track circuit / axle counter detection under a mixed model and fully takes factors affecting the train tracking into account. Thus train tracking efficiency is improved, tracking is accurate and reasonable, and the train is prevented from loss.

Description

technical field [0001] The invention relates to urban rail transit technology, in particular to a train tracking method. Background technique [0002] In the prior art, train tracking is carried out by detecting the occupancy or idle state of the track section through axle counting equipment. When the train enters the track section, the track section is in the occupied state; The section becomes idle, and the position of the train and the direction of the train are tracked through the state transitions on each track section, but there are some defects in the way of only using the occupied or idle state of the track section for train tracking. There can be multiple trains on a section, and a train can also occupy multiple track sections. However, the occupied status of a track section only indicates that there are trains on this track section, and the idle status of a track section only indicates that there are trains on this track section. There are no trains on the section...

[0002] In the prior art, train tracking is carried out by detecting the occupancy or idle state of the track section through axle counting equipment. When the train enters the track section, the track section is in the occupied state; The section becomes idle, and the position of the train and the direction of the train are tracked through the state transitions on each track section, but there are some defects in the way of only using the occupied or idle state of the track section for train tracking. There can be multiple trains on a section, and a train can also occupy multiple track sections. However, the occupied status of a track section only indicates that there are trains on this track section, and the idle status of a track section only indicates that there are trains on this track section. There are no trains on the section. When multiple trains are running on a continuous track section, it may cause congestion, and the position of the train in this situation cannot be distinguished according to the occupied idle state of the track section.
