IoT기반 전동차 주행 실시간 관리 및 데이터 기록 시스템 구축: 광주도시철도공사 사례를 중심으로

Abstract

This study reviewed the innovation case of Gwangju Metropolitan Rapid Transit Corporation, which established a real-time status monitoring and data recording system for core devices for IoT-based train driving in 2021. Gwangju Metropolitan Rapid Transit Corporation tried to contribute to the safe operation of trains by building IoT-based facilities and using them for preemptive preventive inspections. As a result of their innovation efforts, it became possible to check the status of key parts in real time during the operation of the Gwangju Subway Line 1 train to determine whether there is an abnormality in the train. In addition, by collecting and analyzing various data during train operation, it is possible to contribute to the safe operation of trains through preemptive preventive inspections. If more data is accumulated by expanding the application range of IoT in the future, more effective train management will be achieved by predicting failures based on failure patterns of major parts. Therefore, Gwangju Metropolitan Rapid Transit Corporation needs not only to stabilize the current innovation cases, but also to discover research and development and best practices to apply them to more diverse fields based on them, and to continuously supplement them through benchmarking.
