Monitor apparatus and method for identifying electronic apparatus thereof

摘要

A method for identifying an electronic apparatus is provided. The method is adapted for a monitor apparatus in a power system, and includes the following steps of adaptively updating a power signature database related to at least one electronic apparatus; adaptively updating a line resistance database related to the monitor apparatus; detecting whether at least one power signature event occurs; calculating a system impedance of the at least one power signature event when the at least one power signature event occurs; and identifying at least one unknown electronic apparatus resulting the at least one power signature event according to the system impedance, the power signature database and the line resistance database.

1. A method for identifying an electronic apparatus, adapted for a monitor apparatus comprising a detecting module and a processing module in a power system, the method comprising:
adaptively updating, by the processing module, a power signature database related to at least one electronic apparatus, wherein the monitor apparatus is a power meter; adaptively updating, by the processing module, a line resistance database related to the monitor apparatus; detecting, by the detecting module, whether at least one power signature event occurs; detecting, by the detecting module, a steady state power signature of the at least one power signature event; normalizing, by the processing module, the steady state power signature; calculating, by the processing module, a system impedance of the at least one power signature event according to the steady state power signature being normalized; and identifying, by the processing module, at least one unknown electronic apparatus resulting the at least one power signature event according to the system impedance, the power signature database and the line resistance database.
