System Components – Data Acquisition Terminal
It features a modular design, comprising a power module, a communication module, and a data storage module. The power supply is localized and sourced directly from the power supply within the cable termination cabinet. The communication module handles both upstream and downstream communications: upstream, it transmits signals and data to the server; downstream, it collects data gathered by sensors. Meanwhile, the data storage module manages and stores all incoming information.

System Features – Real-Time Monitoring + Early Warning
Gray: Indicates a sensor connection issue or that the sampled value is too low.
Green: indicates the sensor is functioning properly;
Yellow: Indicates that the discharge peak at the sensor's location has exceeded the warning threshold, and this area should be monitored closely.
Orange: Indicates that the discharge peak at the sensor's location is relatively high, exceeding the over-limit threshold in the set values. Strengthen inspection efforts and increase attention to this specific area.
Red: Indicates that the discharge peak at the sensor's location is very high—already exceeding the over-alert threshold. Strengthen inspections at this location and increase monitoring attention.
