Abstract

The invention belongs to the field of coal quality detection and discloses a coal quality online detection and analysis method based on regression analysis. Graphic features of various areas in coal are automatically extracted by regression analysis algorithm of machine learning for image characteristics extraction; and a coal quality online detection result is provided based on the extracted image characteristics by machine learning, and the detection result is displayed through a display module. the method of the invention comprises the following specific steps: a coal scanned image is acquired through data acquisition equipment with built-in near-infrared detection module and laser detection module; the coal scanned image is pretreated by the use of a pretreatment module, and the coal scanned image is divided into multiple blocks. Coal quality data information detection is carried out through the near-infrared detection module and the laser detection module, and the detection data is accurate. By component network for nonlinear prediction, the method of the invention has advantages of strong adaptability, good fault tolerance and the like. All elements analysis of coal quality can be realized, and measurement accuracy also can be enhanced.

Description

technical field [0001] The invention belongs to the field of coal quality detection, in particular to a coal quality online detection and analysis method based on regression analysis. Background technique [0002] In order to understand the quality and combustion characteristics of coal, the assay and testing work is carried out on coal samples by physical and chemical methods. Coal quality analysis is carried out in accordance with national technical standards or special test procedures. It is the basic work that provides basis for the design and operation of related equipment and processes; The specific composition of coal on the belt conveyor, so as to adjust the relevant production parameters according to the change of coal composition. For example, in coal-fired power plants, coal costs account for 80% of the total cost, so it is crucial to understand and study the impact of factors such as coal quality on production efficiency. This requires that the coal on the conv...
