Remote monitoring of device operation by tracking its power consumption

Abstract

Monitoring devices by following and analyzing local current measurements and communicating the data over the power line. Various operation characteristics are extracted from the measurements, such as device profiles, operational status, various deficiencies and user related parameters. Current consumption profiles are derived from the accumulating data, and compared to previous patterns. The monitoring allows controlling operation of the devices, estimating their physical location and communicating messages from the devices regarding e.g. software status, by deliberate operation of the device to generate predefined current use patterns.
