An abnormal detection method for energy consumption of mechanical equipment based on mechanism data fusion

Abstract

The invention discloses a method for detecting abnormal energy consumption of mechanical equipment based on mechanism data fusion. The specific steps of the method of the present invention are: (1) generating the energy consumption data set of the mechanical equipment to be detected; (2) adopting the mechanism data fusion method to calculate the inspection value of the voltage in the voltage data set, and calculate the inspection value of the current in the current data set; (3) The dynamic time programming algorithm is used to calculate the inspection value of the power in the power data set; (4) calculate the voltage state value and current state value of the mechanical equipment to be detected respectively (5) detect whether the energy consumption of the mechanical equipment is abnormal. The invention has the advantages of strong generalization ability for abnormal detection of energy consumption of general mechanical equipment, and reduces the requirements on the type and quantity of sensors, and reduces the complexity of data collection and analysis cost.

Description

technical field [0001] The invention belongs to the technical field of machinery, and further relates to a method for abnormal detection of equipment energy consumption based on fusion of mechanical mechanism data in the technical field of mechanical detection. The invention can be used for detecting the abnormal state of energy consumption in the production process of large mechanical equipment. Background technique [0002] For large-scale manufacturing enterprises, the energy cost caused by equipment energy consumption usually accounts for more than one-third of the production cost of the enterprise. The demand for energy conservation has increasingly become one of the directions for enterprises to transform into refined and resource-friendly manufacturing. Equipment power consumption detection is particularly important. It aims to detect power consumption during equipment operation, and the detection results often reflect the current state of equipment operation. If the...
