Patent ID: 6839597

Claim:
A state-of-device remote monitoring system comprising: an on-the-spot area including: an electric device; a detector for measuring physical and electrical operating characteristics of said electric device; a first communication signal converter for converting detection data obtained by said detector into communication signals, and transmitting the communication signals; and a controller, having a memory for storing the detection data obtained by the detection of said detector, for storing with the detection data a device state based on a preset detection start program, and outputting the detection data stored in said memory to said first communication signal converter based on a preset communication start program that runs in correspondence with storage of the detection data, and a management area including: a second communication signal converter for converting the communication signals received from said first communication signal converter into the detection data; a maintenance tool having a diagnostic/analytic program for analyzing the device state from the detection data converted by said second communication signal converter, and a maintenance database storing data necessary for analysis by said diagnostic/analytic program and a diagnosed result; and a display unit for displaying the diagnosed result obtained by the analysis by said maintenance tool.
