METHOD AND APPARATUS FOR DETECTING DEVICE ANOMALY
First Claim
1. An apparatus for detecting device anomaly, comprising:
- a database configured to store a plurality of electric power features;
a measurement module configured to measure electric power of a device to generate electric power information;
a judgment module connected to the database and the measurement module, configured to judge whether the device is abnormal based on the plurality of electric power features and the electric power information; and
a detection module connected to the judgment module, configured to detect operation states of a plurality of elements in the device to generate a plurality of state signals to the judgment module;
wherein, the judgment module further judges whether each element of the plurality of elements is abnormal based on the plurality of state signals, the electric power information, and the plurality of electric power features.
