Urban waterlogging, caused by heavy rainfall or inadequate drainage systems, poses significant risks to city operations, public safety, and infrastructure. To address this, the Urban Waterlogging Monitoring and Early Warning Solution leverages advanced technologies to provide real-time monitoring, early warnings, and data-driven decision-making tools for city management.
Solution Overview
The solution integrates IoT (Internet of Things), cloud computing, big data analytics, and AI (Artificial Intelligence) to create a comprehensive system for monitoring and managing urban waterlogging. It consists of four main components:
Front-end Sensing Devices: Collect real-time data on rainfall, water levels, and flow rates.
Data Transmission Network: Ensures seamless data transfer from sensors to the central platform.
Data Processing Center: Analyzes data to generate actionable insights and early warnings.
Application Service Platform: Provides a user-friendly interface for monitoring, decision-making, and emergency response.
Key Features
Real-Time Monitoring
The system uses sensors such as rain gauges, ultrasonic water level sensors, and cameras to monitor critical areas like underpasses, tunnels, and low-lying zones. Data is updated in real-time, enabling quick responses to potential waterlogging.
Early Warning Mechanism
When water levels or rainfall exceed predefined thresholds, the system automatically triggers alerts via SMS, broadcasts, mobile apps, and LED displays. This ensures timely notifications to both authorities and the public.
Data Analytics and Visualization
Advanced analytics tools process collected data to identify trends, predict risks, and generate visual reports. 3D modeling and GIS (Geographic Information Systems) are used to visualize waterlogging patterns and support decision-making.
Automated Control and Response
The system can integrate with urban infrastructure, such as drainage pumps and floodgates, to automate responses like activating pumps or closing gates during heavy rainfall. This reduces reliance on manual intervention and improves efficiency.
Customizable and Scalable
The solution is highly adaptable, allowing cities to customize monitoring points, thresholds, and response protocols based on local conditions. It can also scale to cover larger areas or integrate with other smart city systems.
Rainfall monitoring: Since rainfall is the main cause of urban waterlogging, rainfall monitoring is the basis for monitoring urban waterlogging. Through the establishment of rainfall monitoring station network, real-time collection and transmission of rainfall data can understand the rainfall, rainfall intensity and rainfall distribution information, and provide data support for urban waterlogging forecast and early warning.
Water level monitoring: Through the installation of water level gauges in low-lying sections, tunnels and underpasses in the city to monitor the water on the road surface, you can understand the depth and location of water on the road surface, so as to timely flood control.
AI video surveillance: Through the video surveillance system, intelligent AI surveillance cameras can achieve remote monitoring of various waterlogging points, including the identification of water levels, whether there are large objects blocked, face recognition and behavior recognition functions, can quickly locate the alarm location, rapid processing, to avoid the loss of personnel and property.
Early warning release: The system uses LED early warning screen, early warning broadcast, sound and light early warning, wechat mini program, SMS and cloud call to issue early warning. When the water depth of the monitoring point exceeds the warning threshold, the audible and visual alarm will flash, the horn will emit an alarm sound, and the LED screen will display the warning information. At the same time, the remote management platform and mobile phone will also receive real-time warning information.

Platform management: The system can carry out real-time water level monitoring, rainfall monitoring and video/image monitoring of water points in urban areas, and automatically give early warning when the data exceeds the limited range. Through the 4G/5G/LoRa/ fiber optic network, the data is transmitted to the monitoring center cloud platform, and the city management department can use the system to understand the entire urban waterlogging situation, and timely warning linkage and drainage scheduling to avoid major losses.
Long-term control measures for urban waterlogging:
1. Sponge city construction
Permeable pavement, rain garden, sunken green space and other facilities enhance the infiltration and retention capacity of rainwater.
2. Drainage system upgrade
Renovate the old pipe network and expand the pipe diameter; Additional pumping stations, storage tanks and other grey infrastructure.
