It conducts all-round online monitoring of key information including partial discharge, fault status, temperature of cables and channels, grounding circulation, anti-intrusion and anti-theft, as well as environmental gas visualization, toxic and harmful gases, and fire conditions in cable tunnels.
The system achieves in-depth perception, risk early warning, intelligent linkage, and fault diagnosis for cable equipment and tunnel environments. It can accurately identify potential safety hazards in tunnels and issue early warnings, enabling timely disposal before accidents occur, thus providing a solid technical guarantee for the safe and stable operation of the power grid.
Through various denoising algorithms combined with alarm level analysis, minimize false alarms to the greatest extent
Integrated linkage control of local devices
With local edge computing and data management capabilities, it intelligently analyzes monitoring data and actively alarms when data exceeds limits or abnormalities are detected
