摘要:

大型工业系统的工作条件非常复杂。一旦发生故障,将影响工业生产,造成财产损失,甚至危及工人的生命。因此,准确掌握系统的运行状态,及时发现故障,对控制系统的运行至关重要。系统故障的发生是一个渐进的过程,当前系统故障的发生可能取决于系统的前一个状态,这是顺序的。基于时间序列的故障诊断技术可以实时监测系统的运行状态,在允许的时间间隔内发现系统的异常运行,诊断故障的根本原因并预测状态趋势。为了指导技术人员对相关故障进行诊断和解决,本文基于立方DUCG理论实现了一个工业故障诊断系统。基于专家知识和经验建立了系统的诊断模型。同时,它可以进行基于时间序列的实时故障诊断,解决了没有样本数据的工业系统故障诊断问题。

英文摘要:

The working conditions of large-scale industrial systems are very complex. Once a failure occurs, it will affect industrial production, cause property damage, and even endanger the workers' lives. Therefore, it is important to control the operation of the system to accurately grasp the operation status of the system and find out the failure in time. The occurrence of system failure is a gradual process, and the occurrence of the current system failure may depend on the previous state of the system, which is sequential. The fault diagnosis technology based on time series can monitor the operating status of the system in real-time, detect the abnormal operation of the system within the allowable time interval, diagnose the root cause of the fault and predict the status trend. In order to guide the technical personnel to troubleshoot and solve related faults, in this paper, an industrial fault diagnosis system is implemented based on the cubic DUCG theory. The diagnostic model of the system is constructed based on expert knowledge and experience. At the same time, it can perform real-time fault diagnosis based on time sequence, which solves the problem of fault diagnosis of industrial systems without sample data.
