针对带式输送机存在输送距离长、运量大、速度快、使用环境恶劣等问题,基于D—s证据融合理论在处理由不知道所引起的不确定性方面具有独特优势,将D.S证据理论应用于带式输送机故障诊断中。详细论述了D—S证据理论及基于证据理论的带式输送机故障诊断过程。实验表明:D—s证据理论能有效提高诊断可信度,是一种有效的带式输送机故障诊断方法。
In view of the long distance transmission belt conveyor, large capacity, fast velocity, accident is harm to personnel and equipment. Based on D-S evidence theory with the advantage in dealing with the uncertainty, this paper applies the D-S evidence theory in the fault diagnosis of the belt conveyor, discuses the fault diagnosis of D-S evidence theory and the process of belt conveyor fault diagnosis based on evidence theory in detail. Experiment result shows that the D-S evidence theory can effectively improve the diagnostic reliability, and it is a kind of very effective belt conveyor fault diagnosis method.
