Real-time collects parameters such as current, voltage, power, power factor, and electrical energy for overload monitoring: triggers an alarm when the current exceeds the set threshold
Short circuit detection: Identify short-circuit characteristics such as sudden increases in current, trigger emergency alarms, diagnose line aging: identify line aging risks through parameter fluctuation analysis, monitor illegal electricity usage: monitor high-power electrical appliances in unmanned areas that have not been turned off and other violationsThree phase unbalance monitoringHarmonic analysis

Real-time Traffic collection (minute level)
Leak detection: Identify pipeline leaks through abnormal flow rates
Water Monitoring | Nighttime Water Monitoring: Identifying Abnormal Water Use Behavior at Night
Valve not closed detection: Detecting the situation where the valve is not closed after using water. Leakage point positioning: Accurately locate to the floor, room, and specific pipe section
