Solution overview

From rainfall to ponding, one closed flood-control loop

Deploy radar level meters and monitoring terminals at flood-prone roads, underpasses, metro entrances and low-lying areas. Combine drainage flow data, rainfall forecasts and hydraulic models to monitor conditions, warn early and dispatch response resources.

HKI collects rainfall, ponding, network level, flow, pump and video data through a unified wireless architecture. Edge computing keeps critical alarms available even when connectivity is unstable.

The platform turns data into a practical workflow: monitor, warn, dispatch, act and review. Threshold alarms and model forecasts help teams move from emergency reaction to risk prevention.

System architecture

Three layers from sensing to coordinated action

Field devices collect data, secure wireless links transmit it, and the flood-control platform turns it into warnings, dispatch and review.
