Fault detection in the waste incineration process depends on high-temperature image observation and the experience of field maintenance personnel, which is inefficient and can easily cause misjudgment of the fault. In this paper, a fault detection method is proposed by combining stochastic configuration networks (SCNs) and case-based reasoning (CBR). First, a learning pseudo metric method based on SCNs (SCN-LPM) is proposed by training SCN learning models using a training sample set and defined pseudo-metric criteria. Then, the SCN-LPM method is used for the case retrieval stage in CBR to construct the fault detection model based on SCN-CBR, and the structure, algorithmic implementation, and algorithmic steps are given. Finally, the performance is tested using historical data of the MSW incineration process, and the proposed method is compared with typical classification methods, such as a Back Propagation (BP) neural network, a support vector machine, and so on. The results show that this method can effectively improve the accuracy of fault detection and reduce the time complexity of the task and maintain a certain application value.
垃圾焚烧过程中的故障检测依赖于高温图像观察和现场维护人员的经验,这种方法效率低下,容易导致故障误判。本文提出了一种将随机配置网络(SCN)和基于案例的推理(CBR)相结合的故障检测方法。首先,通过使用训练样本集和定义的伪度量标准训练 SCN 学习模型,提出了一种基于 SCN 的学习伪度量方法(SCN-LPM)。然后,在 CBR 的案例检索阶段使用 SCN-LPM 方法构建基于 SCN-CBR 的故障检测模型,并给出了结构、算法实现和算法步骤。最后,使用 MSW 焚烧过程的历史数据进行性能测试,并将所提出的方法与典型的分类方法(如反向传播(BP)神经网络、支持向量机等)进行比较。结果表明,该方法可以有效提高故障检测的准确性,降低任务的时间复杂度,并保持一定的应用价值。
