    Multistage identification method for real-time abnormal events of streaming data by Hao Luo, Kexin Sun, Junlu Wang, Chengfeng Liu, Linlin Ding, Baoyan Song

    Published 2019-12-01
    “…The current mine disaster event monitoring method is a lagged identification, which is based on monitoring a series of sensors with a 10-s-long data waveform as the monitoring unit. The identification method proposed in this article first takes advantages of the dynamic time warping algorithm, which is widely applied in the field of audio recognition, to build an anti-aliasing model and identifies whether the perceived data are disaster signal based on the similarity fitting between them and the template waveform of historical disaster data, and second, since the real-time monitoring data are continuous streaming data, it is necessary to identify the start point of the disaster waveform before the identification of the disaster signal. …”
