DAEJEON, Sept. 2 (Korea Bizwire) – The Korea Railroad Corp. (KORAIL) has developed a new system that uses artificial intelligence (AI) technology to check the core components of subway systems operating in the greater Seoul area on a real-time basis as well as to predict the cycle of subway breakdown.
Supported by the Ministry of Land, Infrastructure and Transport, the system was jointly developed by KORAIL, Hyundai Rotem and the Korea National University of Transportation.
To apply existing state-based maintenance and repair technology to railroad cars, a large computer storage capacity is required to deal with the huge amount of data, as well as an exclusive system to process and analyze such data in a usable format.
The national railway operator developed a large-capacity diagnosis computer and attached AI-connected sensors to six types of core components, including the main air compressor and powder condenser.
By applying a time series model that analyzes data by the lapse of time, the AI automatically checks the remaining life of components, the state of performance, and the cycle of replacement, while predicting the time of maintenance and repair.
KORAIL plans to verify the new system’s performance through a trial application on two subway lines operating in the greater Seoul area starting next month and aims to commercialize it in 2024.
