Accuracy control of train automatic driving parking: a case study of Nanning Rail Transit Line 4

Abstract

This paper aims parking accuracy problem of trains in ATO (Automatic Train Operation) mode, in order to improve the parking accuracy can improve passengers taking on and off efficiency, reduce the dwell time in the station, improve the operation efficiency, as well improve the quality of passenger service as. In the practical application, it has a strong application value. This paper proposes a new balise arrangement scheme for Nanning Rail Transit line 4, in order to improve the parking accuracy. This paper uses the balise information and the non-learning parking algorithm based on Newton mechanics, the arrangement spacing of the balise of Nanning rail Transit line 4 is reset. After optimizing and adjusting the balises spacing of line 4, the accuracy of train automatic driving parking is simulated by using Matlab simulation software. By comparing and analyzing the results of Matlab simulation testing with the results before optimizing the layout of the responder, after optimization, the parking accuracy during the automatic train operation parking process has been improved by 3.33%, which is 1cm higher than the required range of parking accuracy (± 30cm).
