摘要:
基于激光测距技术,提出一种新型皮带输送物料的体积测量方法,该方法利用激光测距传感器拟合得到物料横截面,并结合皮带速度计算得到物料瞬时流量.通过皮带上物料的运动特征分析主要误差源,并优化轮廓提取算法;通过搭建实验台(带宽为200 mm的皮带机),测量在带速为0~0.8 m·s-1时的物料流量.实验结果表明:误差补偿之后,测量结果的重复性和准确性的误差均在±1%以内,该方法具有非接触、结构简单、精度高等优点,可以满足工业带式输送机的实时测量要求.
Abstract:
Based on laser ranging technology, a new method for measuring the material volume on belt conveyors was proposed. A the method uses laser ranging sensor was used to measure and fit the cross section of material and the instantaneous flow rate of material was calculated together with belt speed. According to the movement characteristics of the material on the belt, the main error sources were analyzed and the contour extraction algorithm was optimized. An experimental platform with a bandwidth of 200 mm was set up to measure the material flow rate when the belt conveyer moved at a speed in the range of 0~0.8 m·s-1. The experimental results show that: the repeatability error and accuracy error of measurement results are within ±1% after error compensation. This method has the advantages of non-contact measurement, simple structure and high precision, and can meet the real-time measurement requirements of industrial belt conveyor.
