摘要:

采煤机螺旋滚筒在切割煤岩层时产生的瞬时交变冲击载荷,会引发滚筒多方向振动,且振动状态随切割条件的变化而改变。为避免数据特征从前端向后端传递中的损失,本文提出一种基于D-S融合的煤岩切割状态感知系统。首先从切割部件前端采集切割力和振动作为特征信号,并将相应的变换特征向量输入RBF神经网络,获得单个信号的识别结果,然后在决策层进行基于证据相关系数的D-S融合。该方案能将平均识别准确率提高到96.5%,更准确地判断煤岩截割状态。

Abstract:

The spiral drum of the coal shearer generates instantaneous alternating impact loads when cutting coal and rock layers, causing the drum to vibrate in all directions. The vibration state varies with different cutting conditions. It is difficult to effectively perceive the current cutting state by extracting only a single vibration feature. This paper proposes a coal-rock cutting state perception system based on D-S fusion. Both the cutting force and the two front-end vibration signals are collected as features, and the corresponding transformed feature vectors are input into the RBF neural network. First, the recognition result of a single signal is obtained, and then the D-S fusion based on the evidence correlation coefficient is carried out at the decision-making level. This scheme can increase the average recognition accuracy rate to 96.5%.
