Safe electricity utilization pre-alarm method based on current fingerprint technology

The invention discloses a safe power utilization pre-warning method based on a current fingerprint technology, and the method comprises the following steps: employing the alarm information of power utilization equipment in an operation early stage, and building a transition safety pre-warning basic model in combination with the demands of a user; the method comprises the following steps: continuously acquiring operating parameters of electric equipment through an acquisition terminal, and performing fast FFT calculation to obtain a preprocessing safety early warning basic model; comparing the similarity between the transition safety early warning basic model and the preprocessing safety early warning basic model; and monitoring, comparing and alarming power utilization in real time by using the final model library. According to the invention, the current operation state of the monitored equipment, the field operation rule and the safe operation mode can be accurately judged based on the special current finger
