System Architecture – Data Acquisition Terminal
It adopts a modular design, comprising a power module, a communication module, and a data storage module. The power supply is localized, drawing from the power source within the cable termination cabinet. The communication module handles both uplink and downlink communications: the uplink transmits signals and data to the server, while the downlink aggregates data collected by the sensors. The data storage module performs data management and storage.

System Function – Real-Time Monitoring + Early Warning
Gray: Indicates a sensor connection error or that the sampled value is too low.
Green: Indicates that the sensor is operating normally;
Yellow: Indicates that the discharge peak at the sensor’s location has exceeded the warning threshold, and this location warrants attention.
Orange: Indicates that the discharge peak at the sensor’s location is relatively high, exceeding the over‑threshold value in the set parameters. This calls for intensified inspection and heightened attention to this location.
Red: Indicates that the discharge peak at the sensor’s location is very high, exceeding the over‑limit alarm threshold. Increase inspection frequency and monitoring intensity for this location.
