Equipment abnormity diagnosis method based on energy consumption interval prediction

The invention discloses an equipment abnormality diagnosis method based on energy consumption interval prediction, and solves the problem that the energy-saving deployment of production operation and maintenance links is affected by misjudgment easily caused by judging energy consumption according to a fitted curve in the prior art. According to the method, whether the equipment is abnormal or not, whether the equipment has an energy-saving space or whether the equipment breaks down or not is judged, data support is provided for operation and maintenance of the equipment, and the reason possibly causing too high energy consumption can be found out for the equipment with too high energy consumption by calculating the correlation coefficient of the energy consumption value and the related variable, data support is provided for taking measures to reduce energy consumption later; and equipment with low energy consumption can be checked and maintained. The energy consumption condition of each device is monitored i
