Abstract
The traditional rolling stock maintenance model based on planned repairs and fault repairs cannot meet the needs of the rolling stock operation and maintenance for superlarge-scaled networks. There is an urgent need to establish a highly automated and information-based rolling stock intelligent operation and maintenance system based on online monitoring. This paper introduces the composition, main functions and application situations for the Shanghai rail transit intelligent rolling stock operation and maintenance system as well as suggestions for further work related thereto so as to provide references for the development of the rolling stock intelligent operation and maintenance system of the rail transit industry.
Highlights
Current Status of Rolling Stock Operation and MaintenanceShanghai Metro has accumulated over 20 years of historical experience in rolling stock operation and maintenance
As early as 10 years ago, Shanghai Metro carried out researches on related aspects of rolling stock intelligent operation and maintenance, and conducted continuous explorations and experiments on train-borne wireless transmission, train-borne online monitoring and trackside monitoring for running trains
The Shanghai metro rolling stock intelligent operation and maintenance system can achieve full coverage status monitoring and data acquisition for key components of rolling stock, shorten maintenance time of the whole lifecycle equipment management, effectively reduce failure risks during the online operation of rolling stock, improve operation quality and ensure operation safety; at the same time, it can significantly reduce the costs for maintenance and guarantee, increase the efficiency for maintenance guarantee and improve equipment reliability
Summary
Shanghai Metro has accumulated over 20 years of historical experience in rolling stock operation and maintenance. In dealing with the rolling stock operation and maintenance for the operation of a superlarge-scaled network, traditional maintenance methods have problems such as high maintenance intensity, low efficiency and high labor costs. As early as 10 years ago, Shanghai Metro carried out researches on related aspects of rolling stock intelligent operation and maintenance, and conducted continuous explorations and experiments on train-borne wireless transmission, train-borne online monitoring and trackside monitoring for running trains. Shanghai Metro has undertaken a national demonstration project for the intelligent operation and maintenance of urban rail transit rolling stocks. The Shanghai metro intelligent rolling stock operation and maintenance system has implemented a network-based intelligent monitoring across the entire rapid transit network in Shanghai.
