Optimization Research on the Rain and Snow Mode of the Fully Automatic Operation System of Rail Transit
The fully automatic operation control system is based on the premise of unmanned driving,and is designed to reduce the risk of train slip in rainy and snowy weather on outdoor/elevated lines due to the possibility of train slip due to wet track surface,which may affect driving safety.A dedicated rain and snow mode control system is de-veloped to reduce the risk of train slip.However,significantly reducing the train speed limit in rain and snow mode will have a significant impact on the efficiency of line operation and cannot effectively meet the actual operational needs.It is also an urgent pain point for line operation departments when using rain and snow mode in practice.This article focuses on the Yanfang line(an open-air elevated line),a typical fully automatic operation line in Bei-jing,and analyzes and studies the speed limit improvement in the rain and snow mode of the fully automatic opera-tion system.While ensuring the safety of the system's vehicle control,an effective solution for the speed limit im-provement in the rain and snow mode is developed,providing reference for the future fully automatic operation system to improve the operational usability in the rain and snow mode of the line.
