Smart Flood Control: Donghua Software’s IoT, Big Data & Cloud Solution

Case Overview

Case Name: Donghua Software Smart Flood Control and Drainage Solution

Source: Donghua Software Co., Ltd.

Industry: Smart City – Water Services

Technology Areas: Big Data, eLTE, Internet of Things, Cloud Infrastructure

Huawei Products: FusionInsight HD, eAPP610, OceanConnect, NB‑IoT, FusionSphere OpenStack

Solution Description

Using IoT, cloud computing, mobile connectivity and big‑data technologies, a unified digital platform for city drainage and flood control is built, offering map‑based rain‑storm status, facility management, intelligent planning, business approval, early warning, and emergency dispatch.

Business Background

Rapid urban growth has outpaced drainage upgrades, leading to frequent flooding. Government directives call for digitalization of drainage, integrating GIS, GPS, remote sensing, and building a comprehensive information platform for monitoring, forecasting, and risk assessment.

Industry Pain Points

Unclear asset inventory and fragmented responsibility.

Lack of integrated data and visual management of pipelines.

Inadequate maintenance funding and “no‑owner” facilities.

Unclear operational status hampers supervision.

Disconnected field and dispatch networks.

Subjective planning without data‑driven support.

Challenges

Ensuring safety and user experience across diverse assets and devices.

Incomplete network coverage.

Information silos and “chimney‑style” development.

Customer Requirements

Real‑time perception of pipeline status via sensors, comprehensive asset management, clear water quality and quantity reporting, enhanced approval processes, and improved emergency response efficiency.

Solution Architecture

Perception Layer: IoT sensors (manhole water level meters, electronic water gauges) collect rain, flow, and disaster data.

ICT Infrastructure Layer: Huawei FusionSphere provides pooled compute, storage, and network resources with elastic services.

Platform Layer: Sensor data is ingested into an IoT platform and processed by Huawei’s big‑data analytics for hydraulic and water‑quality modeling.

Application Layer: Integrated platform delivers services such as a unified asset map, monitoring network, intelligent planning, operation management, design assistance, automated gate control, construction management, and emergency dispatch.

Key application functions include:

One‑map asset visualization and analysis.

One‑network real‑time monitoring.

Intelligent flood‑prevention planning with GIS.

Operation management for maintenance and mobile inspection.

Design support for compliance checking.

Automated gate opening based on real‑time data.

Electronic approval workflow with GIS integration.

Three‑stage emergency dispatch (pre‑, during‑, post‑event).

Successful Deployments

Examples include:

Gaoping County smart drainage (eLTE‑IoT) launched in 2017, providing water‑level monitoring and rain‑gauge integration for flood preparedness.

Guangzhou 1918 IoT industrial park (NB‑IoT) deployed in 2017, enabling comprehensive pipeline monitoring and data‑driven supervision.

Huawei Open Capabilities Used

NB‑IoT end‑to‑end solution with APIs for device development, data transmission, and command control. Devices use LiteOS and NB‑IoT, offering long battery life (up to 5 years) and robust coverage.

Data is reported to OceanConnect platform via southbound interfaces; northbound APIs provide device management, data collection, and command issuance.
