Problems solved by technology

[0005] The technical problem to be solved by the present invention is that under severe weather conditions, after the existing train control system starts the anti-skid control, the vehicle automatically reduces the braking force, resulting in a decrease in the vehicle braking rate. The braking rate does not meet the requirements of the train control system. The braking rate parameter reduces the accuracy of train stopping and may cause overspeed emergency braking

Abstract

The invention discloses a train control method for dealing with severe weather. The method includes the steps that step1, the forward speed of a wheel set is obtained, the difference between the forward speed and reference speed is calculated to obtain a ratio alpha of the difference to the reference speed, and the trackslip conditions of a train are determined by comparing the ratio alpha with a trackslip threshold value w; step 2, corresponding trackslip control is implemented according to the trackslip conditions of the train.

Description

technical field [0001] The invention relates to the field of train control, in particular to a train control method for coping with bad weather. Background technique [0002] Rail transit train automatic control technology is playing an increasingly important role in traffic command and train safety and efficient operation, and has become an important basis for operation. With the large-scale development of rail transit, the pressure on the operation of new lines has increased sharply, and the requirements for autonomous driving have become higher and higher. [0003] The train control system is the key technology of the rail transit train automatic operation system. It is the basis for implementing automatic train control, driving command automation and train operation automation. It directly involves system operation stability and train operation efficiency. [0004] At present, in the construction of rail transit, there are a large number of ground sections. Under severe...
