PROBLEM TO BE SOLVED: To simplify a device configuration as well as identify a load device that is located in each multi-site and is connected to a power supply, to remotely manage the identified load device.SOLUTION: An asset management system 10 comprises: measurement means 3 for measuring a load current waveform W of a power supply 2 to which a plurality of load devices 1 are connected; transmission means 4 for transmitting measurement data on the load current waveform W and measurement position data on a position at which the measurement has been performed; a waveform separation filter 7 for separating an individual load current waveform from the load current waveform; a database 6 in which load device characteristic master data including data on a characteristic of the individual load current waveform and individual information on the load device are stored; load device identification means 8 for identifying a load device 1 by generating individual load apparatus characteristic data obtained by characterizing each individual load current waveform before comparing the individual load apparatus characteristic data with the load device characteristic master data; and management means 9 for comparing the identified load device's measurement position data with its individual information to update the individual information.SELECTED DRAWING: Figure 1 |
