AI Technical Summary
Existing underground cable channel monitoring and control technologies suffer from problems such as low fault early warning accuracy, high false alarm and missed alarm rates, disconnect between monitoring and control, weak closed-loop control capabilities, insufficient multi-source heterogeneous data processing capabilities, and insufficient model generalization capabilities.
A dual-task joint measurement and control system is constructed by employing a multi-source data acquisition module, a data preprocessing module, a multi-level feature extraction module, a measurement and control model inference module, a closed-loop execution control module, and a visualization and early warning module. This system enables standardized processing and feature extraction of multi-source data. Combined with a Transformer encoder and a multi-head attention mechanism, it provides end-to-end output for fault early warning and control decisions, and optimizes the system through closed-loop execution and model iteration.
It enables early warning of potential faults, reduces false alarm and missed alarm rates, improves the lead time and accuracy of fault warnings, realizes adaptive closed-loop control in the fault development process, adapts to the operation and maintenance needs of the entire life cycle of cable channels, reduces the probability of fault escalation, and improves the power supply reliability and operation and maintenance management efficiency of urban power grids.
