Railway vehicle network control system based on artificial intelligence

Abstract

The in-vehicle network communication system and the in-vehicle network control system are independent and inseparable, and the network performance and control performance affect and restrict each other. The purpose of this paper is to study the optimal design of a network control system for railway vehicles based on artificial intelligence. This article is a project actually implemented relying on the railway vehicle network control system in M province. This paper selects the MVB network that conforms to the IEC61375-3 standard through the analysis and comparison of several mainstream communication networks in the rail transit industry. In the process of network topology design, the network system is divided into two network segments, the vehicle network and the train network, through the rational use of repeaters. There are a total of 160 CCU source ports and sink ports. In the process of designing the network control system, we have fully considered various redundancy design schemes, such as master control redundancy, line redundancy, key signal redundancy, hard cable signal redundancy, etc., to ensure the stability and reliability of the entire system. In order to achieve the design goal of subway vehicles mainly based on network control and supplemented by hard line control.

Research on the Classification Method of CTC Alignment Joint-Test Problems Based on RoBERTa-wwm and Deep Learning Integration

“…CTC (Centralized Traffic Control) system, as an important part of high-speed railroad signal system, is an important guarantee for high-speed railroad to achieve high speed, high density, high efficiency and safe and punctual operation, and plays a very important role in high-speed railroad train transportation command and signal control system, which is the core carrier of signal equipment service transportation production [1]. Previously, a large amount of multifarious and heterogeneous problem data has been accumulated during a large amount of alignment joint-test works of the centralized dispatching system.…”
