도시철도 시설물 전자부품(PCB) 자체 수선을 통한 비용절감 사례

Urban rail system has a variety of engineering and system such as machinery, electronics, electric power and so on, in which those of them are linked to each other as one in order to provide a safe and convenient transportation. A stable and safety operation is number one priority to provide a good quality service and to meet passengers’ needs. A shortage of duration of all the system belong to rail system due to 24 hours operating requires high cost of maintenance and operation, of which situation can affect stability. It is one of the best option to organize an independent department repairing and conducting on PCB, which is electronically damaged, malfunctioning and so on. This study has been struggling to verify cost-down effect on operation by specializing in PCB only within a company authorized department and to introduce how to build facilities and groups for self-repairing PCB.
