基于卷积自编码器的综合传动异常检测研究
Research on Integrated Transmission Anomaly Detection Based on Convolutional Autoencoder
摘要
Abstract
To address the challenges in the integrated transmission devices of special vehicle working process,including complex data,the imbalance between normal and abnormal data and the high false alarm and underreporting rates of traditional statistical methods in detecting sensor anomalies,a new method,called ACA-SVM anomaly detection method,combining an attention mechanism convolutional autoencoder(ACA)with a support vector machine(SVM)is proposed.Using operation data from armored tracked vehicles,the monitoring data from integrated transmission sensors is preprocessed.Key features in the transmission data are identified and focused by the attention mechanism.The convolutional autoencoder(CAE)then reduces the dimensionality of the original data and extracts features to facilitate data detection,resulting in the calculation of reconstruction errors and eigenvalues.The support vector machine classifies and calculates the abnormal scores of the training set data samples,and the detection performance is compared with the traditional anomaly detection models.Experimental results show that the proposed ACA-SVM method outperforms CAE,gated recurrent unit(GRU),and other models in detecting anomalies in the integrated transmission data of special vehicles,achieving a detection accuracy of 97.2%and an F1 of 0.976.关键词
