Abstract

The invention discloses an aluminum profile extruder energy consumption abnormality detecting method. The aluminum profile extruder energy consumption abnormality detecting method comprises the following steps: (A) data acquisition: aluminum profile extruder energy consumption data is acquired; (B) data preprocessing: the aluminum profile extruder energy consumption data in an energy database is preprocessed; (C) an energy consumption data mode abnormality detecting model is built; and (D) an energy consumption curve sample is built according to the energy consumption data mode abnormality detecting model; and the abnormality positioning is performed on the aluminum profile extruder energy consumption by using a wavelet neural network. The aluminum profile extruder energy consumption abnormality detecting method realizes timely detection of the extruder abnormality and precise positioning of the energy consumption abnormality part to guarantee smooth production and the product pass percent.

Description

technical field [0001] The invention relates to the technical field of energy consumption detection of extruders, in particular to a method for detecting abnormal energy consumption of aluminum profile extruders. Background technique [0002] Cleaner production of aluminum profiles (resource consumption, energy saving potential, waste production, etc.) is a new strategy throughout the entire production process of aluminum profiles. As the core equipment for the production of aluminum profiles, the extrusion machine integrates machinery, electricity, hydraulic pressure and computers. It has a complex structure and consumes a lot of energy. Its operating status directly determines the quality of the profiles and energy consumption. In the actual production process, the extruder operates under complex operating conditions and is in full-load operation for a long time, which leads to a high probability of abnormal energy consumption and it is difficult to determine the cause of ...
