APPARATUS AND METHOD FOR ESTIMATING MALFUNCTION OF POWER FEEDING EQUIPMENT FOR SUBWAY

摘要

According to the present invention, a subway electricity facility breakdown estimation device comprises: a signal acquirement unit acquiring an electrical signal of a subway electricity facility which supplies power to a subway; a breakdown sign estimation module generating analysis information by analyzing an electric signal acquired by the signal acquirement unit, and breakdown estimation information of a subway electricity facility depending on a result of comparison between the analysis information and pre-stored breakdown sign attribute information; and an output unit outputting breakdown sign information of a subway electricity facility depending on an estimation result of the breakdown sign estimation module.
