Research on Low Energy Consumption Operation Control System of Conveyor Based on Laser Measurement
In view of the fact that the belt conveyor transportation system in Lilou Coal Mine mainly adopts the rated maximum speed operation mode during the operation process,which cannot adjust the belt speed in real time according to the coal quantity condition on the conveyor belt.In the actual operation,there exists problems that the full load rate of the conveyor belt is sometimes high and sometimes low,and the operation cost of the conveyor is relatively high.Starting from improving efficiency,reducing energy consumption,reducing wear and tear,and improving the service life,a coal quantity accurate identification system based on laser measurement and a frequency conversion speed regulation system renovation scheme are proposed.The precise identification of coal quantity on the conveyor belt is achieved using laser segmentation technology and laser stripe center extraction algorithm;The use of frequency conversion speed regulation and closed-loop feedback control technology enables the conveyor to automatically adjust the belt speed according to the coal quantity during the operation process.The practical application shows that after the transformation,the coal quantity recognition system has a deviation of±1.1%in coal quantity recognition.Under the same conditions,the operating speed of the conveyor belt is reduced by 24.8%,the conveying efficiency and operation economy of the belt conveyor are improved.
