Excavator energy consumption analyzing method based on working stage recognition

Abstract

The invention discloses an excavator energy consumption analyzing method based on working stage recognition. The method comprises the following steps of reading double-pump pressure data from a CAN bus of an excavator driving controller, carrying out filtering and frequency reducing, and intercepting pressure data to be recognized; extracting and normalizing feature vectors, inputting into a libSVM model matched with the sampling frequency of the driving controller to recognize the working stage of the excavator, correcting the recognition result by an intelligent verification link; carrying out energy consumption analysis of the excavator according to the instantaneous fuel consumption rate data, outputting the working state and oil consumption state of the excavator to a display unit, and uploading the result to an internet of things platform of the excavator through an external connection controller. According to the method, CAN bus data is fully utilized, the libSVM model established based on a plurality of frequency training sample signals and the system sampling is adopted to reduce the data volume of the pressure signals, and the applicability and the instantaneity of the method is improved, the remote monitoring of the excavator is realized through the internet of things platform, and a reference and a basis are provided for energy conservation and consumption reductionof the excavator.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an excavator energy consumption analysis method based on working phase identification. Background technique [0002] Excavators, as a typical construction machinery, are widely used in my country's urbanization construction and large-scale water conservancy and railway project construction. Due to the complex and changeable working conditions of the excavator and the low operating efficiency of the whole machine, the analysis of the energy consumption in each stage of the excavator's working cycle is an important basis for the excavator to save energy and reduce consumption. [0003] Identifying the working stage of the excavator is the basis for the energy consumption analysis of each stage of the working cycle. At present, there are mainly three types of methods: one is to use the action of the actuator as the identification basis, and match the actions of each j...
