A multi points ultrasonic detection method for material flow of belt conveyor

摘要: 针对单点超声测距技术用于带式输送机物料流量检测时,在煤块分布不均或存在较大煤块情况下测量误差较大的问题,提出了一种基于多点超声对向测距技术的带式输送机物料流量检测方法。该方法通过对物料表面和胶带表面进行多点坐标定位,计算出物料近似截面积,结合带式输送机运行速度,得出物料流量。试验结果表明,在运输煤块较大且不均匀的情况下,该方法的检测误差较单点超声测距技术小。Abstract: For large detection error of single point ultrasonic ranging technology used in material flow detection of belt conveyor when coal distributed unevenly or was big, a material flow detection method of belt conveyor based on multi points ultrasonic counter ranging technology. The method can calculate approximate sectional area of material by locating multi points on surfaces of material and belt, so as to get material flow according to running speed of belt conveyor. The test result shows that the method has smaller detection error than the single point ultrasonic ranging technology under the condition of big coal with uneven distribution.
