SEOUL, Jan. 30 (Korea Bizwire) — Seoul Metro, the operator of subway lines 1-8, has developed a system that uses big data and Internet of Things (IoT) technology to anticipate signs of defects on subway trains.
Condition Based Maintenance (CBM) uses IoT technology to analyze the operational data of trains and defect records collected by the Train Control and Monitoring System (TCMS), a device that works similarly to black boxes on aircraft, and notify staff on signs of defects.
From now on, CBM will replace employees who were previously in charge of, for instance, checking the status of train wheels and selecting optimal dates for maintenance.
Seoul Metro, jointly with South Korean ICT service provider Snet Systems Inc., started work on what ended up being a 12-month project in December of 2018.
The system was installed in the train depot for subway line 2, and is being considered for introduction on subway lines 3 to 8.
“We plan to introduce the new system to increase the efficiency of our maintenance work, and anticipate the signs of a defect in critical devices,” said Choi Jeong-kyun, interim CEO of Seoul Metro.
