摘　　要：针对现阶段多根电缆故障检测效果不佳的问题,提出基于双向LSTM和激光散射信号的多电缆故障自动化同步探测方法。首先,通过激光散射设备同时采集多根电缆的激光散射信号;其次,通过非线性匹配追踪方法获取电缆激光散射信号的波形特征数据,并将此作为电缆故障探测模型的输入;最后,在双向LSTM模型中引入注意力机制,基于改进双向LSTM模型完成多电缆故障自动化同步探测。实验结果表明,所提方法的多电缆故障自动化同步探测准确度更高、精度更高、且更适合于实际应用。A multi cable fault automatic synchronous detection method based on bidirectional LSTM and laser scattering signals is proposed to address the current issue of poor detection performance for multiple cable faults.Firstly,collect laser scattering signals from multiple cables simultaneously through laser scattering equipment;Secondly,the waveform characteristic data of the cable laser scattering signal is obtained through nonlinear matching tracking method,and this is used as input for the cable fault detection model;Finally,attention mechanism is introduced into the bidirectional LSTM model to achieve automated synchronous detection of multiple cable faults based on the improved bidirectional LSTM model.The experimental results show that the proposed method has higher accuracy and precision in automatic synchronous detection of multiple cable faults,and is more suitable for practical applications.
