As urbanization accelerates and extreme weather events become more frequent, cities face growing safety pressures in drainage and flood prevention. Traditional flood management often relies on manual inspections and experiencebased judgment, which leads to significant monitoring blind spots, delayed information sharing, and slow emergency responses.

During sudden heavy rainfall or storms, management departments often lack realtime visibility into the actual conditions of lowlying road sections, underground tunnels, drainage pipe networks, and pumping stations. This makes it difficult to detect flooding hazards in a timely manner and to coordinate flood control efforts effectively, often resulting in severe urban flooding that threatens the safety of people and property. Therefore, urban management departments urgently need to establish a comprehensive, realtime, and intelligent monitoring and early warning system for drainage and flood prevention—shifting the approach from passive emergency response to proactive prevention.

To address this need, WideIOT provides hydrological and water conservancy gateways that can be deployed in key areas such as floodprone urban locations, underpasses, underground spaces, critical nodes of drainage networks, and drainage pumping stations. These gateways connect to electronic water gauges, level sensors, flow meters, rain gauges, cameras, and pump PLC control panels. They collect realtime multidimensional data including water levels, rainfall, flow rates, flow velocity, and equipment operating status. The data is transmitted via 5G/4G networks to management department platforms, enabling remote monitoring, alerting, management, control, inspection, and statistical analysis—providing comprehensive and reliable data support for drainage and flood prevention efforts.

Key Features

Managers can view realtime information on flooding depths at vulnerable points, pipe network water levels, pumping station status, and live video feeds across the city through a command center dashboard or mobile devices, with GIS map integration. This enables a complete, unified view of the urban drainage system on a single screen.

The system supports customizable safety thresholds for water levels, rainfall, and other parameters. When monitored data becomes abnormal or exceeds levels, the system triggers multilevel alerts and automatically notifies management personnel via SMS, WeChat, email, and other methods, allowing timely action.

Using realtime water level and flow data, managers can remotely and precisely control pump start/stop and valve opening/closing at drainage pumping stations. This enables "prelowering of water levels before rain and smart pumping during rain," significantly improving drainage efficiency.

The gateway is designed for industrialgrade reliability and supports data resumption after disconnection. If network signals become unstable or are interrupted during heavy rain, the gateway automatically stores data locally. Once the network is restored, the data is automatically retransmitted, ensuring the integrity and continuity of critical flood control data.

By aggregating historical hydrological data and realtime rainfall information, the system provides strong data support for urban flood risk assessment, flood control material dispatch, and emergency response planning. This helps advance urban flood management toward a more digital, refined, and intelligent approach.
