Seoul Metro developed the ‘Condition Based Maintenance (CBM) System’ for inspection of signs of subway troubles and early action against breakdowns through use of Fourth Industrial Revolution technology like big data and the Internet of Things (IoT).
The ‘CBM System’ leverages big data collected through the TCMS (Train Control and Monitoring System), a system that acts like a black box of an airplane, and bases it on IoT for automatic, real-time collection of information. The system analyzes the information with records of garage maintenance and delivers information about predictive maintenance to workers.
Seoul Metro explained that this system is a step upgraded from the existing maintenance system in preventing accidents and the safe operation of subways will be reinforced in the future.
Seoul Metro is also examining the application of the system technology to Subway Lines 1-8 in addition to Subway Line 1 and is considering ways to advance this technology overseas.
