AI Technical Summary
Existing technologies are unable to effectively handle the spatiotemporal heterogeneity of multi-source machine alarm events in railway stations, resulting in difficulties in tracing the source of safety risks, unclear causal relationships, and high false alarm and missed alarm rates.
By constructing a spatiotemporally heterogeneous event sequence, a master-slave coupled phase-locked loop (PLL) model is established to achieve phase synchronization mapping between machine alarm events and manual operation events. The PLL synchronization state is dynamically determined, triggering segmented locking and PLL reconstruction. A weighted spatiotemporal causal propagation network is also constructed to perform causal propagation link analysis.
It significantly improves the synchronization stability and robustness of railway station safety alarm information, reduces the false alarm and missed alarm rates, and enhances risk warning and emergency response capabilities.
