An Integrated Maintenance Information System for EMU

초록

Urban transit operation corporations perform repetitive works to investigate the electric multiple units, by some fixed maintenance cycle. The quality of maintenance work usually depends on workers’ know-how. Though some information to support the maintenance work is digitalized and provided to workers, it is not great help to them because of its non systematic structure. The information includes drawings, manuals, work results, work history, fault history, etc. The maintenance workers want to access the information anytime anywhere, and make an effort to promote the efficiency of maintenance work for EMU. But it is difficult to achieve that without some structured information system which is able to be used in the works. So we develop maintenance information system for EMU for about 4 years from 2002 to 2005. In this paper we present the configurations and characteristics of the system, and the results of the certification test. We install the system in two depots, Changdong and Jichuk, belonged to Seoul Metro to evaluate its efficiency.
