Abstract

The invention discloses a chaos theory and integrated learning-based coal mining machine cutting height prediction system. The system is used for predicting the cutting height of the coal mining machine. The system comprises a data preprocessing module, a Chaotic characteristic calculation module, a Phase space reconstruction module, a coal mining machine cutting height extreme gradient boosting (eXtrome Grade Boosting) modeling module, and a coal mining machine cutting height extreme gradient boosting (eXtrome Grade Boosting, XGBoost) model prediction module. The chaotic characteristics of the cutting height sequence of the coal mining machine can be mined, and the cutting height of the coal mining machine can be quickly and accurately predicted.

Description

Technical field [0001] The invention relates to the field of signal processing, the field of chaos theory and the field of integrated learning, in particular to a shearer cutting height prediction system that combines chaos theory and integrated learning. Background technique [0002] Currently, countries all over the world are striving to develop their economies, and energy demand continues to grow. Coal accounts for a huge proportion of the world's primary energy consumption. However, safe coal production has always been an important factor restricting coal production. Therefore, it is very important to vigorously improve the automation, mechanization, and information level of the coal mining process. As the key equipment of the coal mining face, the shearer is of great significance in the coal mining production process. The adjustment and control of the height of the cutting drum is the key process of manual operation of the shearer when the shearer is mining coal in the und...
