Method and system for determining train set length based on axle counting sensor

Abstract

The invention provides a method and system for determining the length of a train set based on an axle counting sensor. The method comprises the steps that first axle counting information of the train set passing through a first axle counting sensor is obtained; acquiring real-time displacement information of the train set passing through the first axle counting sensor; and determining the train set length according to the first axle counting information and the real-time displacement information. According to the method and system for determining the train set length based on the axle counting sensor, the train set length can be measured in real time based on the acquired axle counting sensor information and train set displacement information, and the precision is high.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and in particular relates to a method and a system for determining the length of a train based on an axle counting sensor. Background technique [0002] The length calculation of trains (usually a train consisting of multiple carriages) is usually applied in marshalling yards. The length of the train is mainly used to judge the safety protection distance. There are two main methods for judging the train length at present, one is to obtain the train length from the planning information, and the other is to use the occupied and clear state of the track circuit to determine the train length. The specific method of using the track circuit to determine the train is as follows: drive into the track circuit section at a constant speed, detect whether the track circuit is cleared through the interlocking system, judge the difference between the occupied time and the clearing time, and use "speed * ...

AI Technical Summary

Problems solved by technology

[0003] Use plan information to obtain train length. When the plan information is wrong or insufficient, it is impossible to obtain train length information in a timely and correct manner.

Also, there is a lack of a process for verifying train lengths on site

On-site real-time measurement of the train length usually adopts the track circuit method, but the track circuit occupancy and clearing judgments are affected by the delay of the track circuit and the related interlocking system delay, and the delay length is uncertain. large error
