MONITORING POWER USAGE

摘要

Disclosed are various embodiments for monitoring power usage. A plurality of power usage cycles are monitored using a controller. Each of the power usage cycles includes a plurality of current draw periods. Each of the current draw periods has a different average current draw. A current draw reading is determined to be abnormal when the current draw reading meets a threshold associated with one of the current draw periods, while the one of the current draw periods is predicted to be active. An action is performed when the current draw reading is determined to be abnormal.

主权项

1. An apparatus for monitoring power usage, comprising:
a power receptacle; a power plug; a current sensor configured to read current drawn through the power receptacle; and a controller configured to execute a program, the program comprising:
logic that generates power profile data indicating a plurality of automatically detected current draw periods, the power profile data being generated based at least in part on monitoring current draw with the current sensor when a learning mode is active;logic that determines that one of the automatically detected current draw periods is active based at least in part on the power profile data;logic that determines that a current draw reading is abnormal when the current draw reading meets a threshold associated with the one of the automatically detected current draw periods that is active; andlogic that performs an action when the current draw reading is determined to be abnormal.
