Urban waterlogging refers to the phenomenon of water accumulation disasters in cities due to heavy precipitation or continuous precipitation exceeding the city's drainage capacity. With the acceleration of climate change and urbanization, urban waterlogging has become more frequent and serious. Traditional urban drainage systems have been unable to meet current urban drainage needs. Especially under extreme weather conditions such as heavy rain, urban drainage systems can easily overload, causing serious waterlogging disasters. Urban waterlogging not only affects citizens 'daily life and travel safety, but may also cause damage to the city's transportation, electricity and other infrastructure, and even cause secondary disasters. Therefore, in order to effectively respond to the risk of urban waterlogging, countries have invested a large amount of money and manpower to develop urban waterlogging monitoring and early warning systems. The system monitors rainfall, water level and other data in various areas of the city in real time, and combines meteorological, hydrological and other information to provide early warning and assessment of urban waterlogging risks, providing strong support for urban flood control work. Through real-time monitoring and early warning, relevant departments can respond quickly, take effective measures to deal with water accumulation problems, and reduce disaster losses. At the same time, waterlogging monitoring data can also guide the optimization and upgrading of urban drainage systems, improve drainage capacity, and fundamentally solve the problem of water accumulation.

project value

The urban waterlogging monitoring and early warning system solution is an efficient and accurate means of waterlogging early warning and Incident Response Service. By integrating advanced sensor technology and data analysis algorithms, it can monitor the operating status of urban drainage systems in real time, providing city managers with comprehensive and intuitive real-time operating status of the drainage system. This system can help managers discover bottlenecks and potential problems in the drainage system in a timely manner, such as pipeline blockages, pumping station failures, etc., so as to adopt effective preventive measures and Incident Response Service strategies. Through this solution, urban management efficiency can be significantly improved and traffic interruptions, business losses and inconvenience caused by waterlogging can be reduced. More importantly, it can protect the safety of people's lives and property, reduce the risks and losses caused by waterlogging disasters, and provide solid technical support for the sustainable development of cities.

system function

③ Online monitoring: Use GIS geographical information systems, analog data maps, online videos and other methods to comprehensively reflect the actual operating parameters of water accumulation in low-lying areas. You can view the distribution of monitoring stations at each water level station and water accumulation point, the current water level, warning water level, power supply information and equipment operating status.

█排涝管理：对排涝及其相应的预案信息、基础资料、周边环境、数据报表等进行集中管理，使排涝管理更加信息化、自动化。

③ Forecasting and early warning: Analyze and interpret various monitoring data in real time to realize single or multiple comparison alarm functions. When the accumulated water data exceeds the preset threshold, the system will release early warning information through LED prompt screens, sound and light alarms, text messages pushed to mobile phones, mobile apps and other methods to ensure that forecasts and warnings are processed in a timely manner.

█系统管理：为信息发布平台提供了良好管理支持，使信息发布平台更加灵活、更易扩展。

丨 Intelligent linkage: The system can judge the arrival of floods in advance based on urban waterlogging flood control parameters, and link LEDs to release information in real time, and at the same time link on-site drainage equipment to provide timely drainage to avoid and delay the occurrence of urban waterlogging.

③ Weather forecast: According to specific city positioning, real-time display satellite cloud images, radar maps, time-sharing weather forecasts and seven-day weather forecasts to provide meteorological support for urban waterlogging warning.

system composition

The urban waterlogging monitoring and early warning system also has the characteristics of wide application range, multiple types of sensor collection, diversified early warning release, and integrated installation. It can monitor water accumulation in low-lying areas on roads, underpass overpasses and tunnels in real time, and transmit it remotely to the monitoring center through 4G/5G networks. The system integrates multiple sensors such as rainfall collection, image collection, and water level collection. Through system forecast analysis, early warning information is released in a timely manner. The methods of releasing early warning information include broadcasts, LED electronic screens, warning lights, text messages and other methods to ensure the safety of citizens 'travel and promptly prevent people and vehicles from accidentally entering deep water sections and causing major personal injury and property damage. The plan mainly consists of on-site monitoring stations and monitoring center platform software.

现场监测站：配备了雨量传感器、电子水尺或雷达水位计、流速或流量传感器、水质传感器、气体传感器、视频监控、声光报警器、LED显示屏、遥测终端机和电源系统等设备。These devices can monitor rainfall, water level, flow rate, water quality and other information in real time, and provide on-site images through video surveillance to detect and deal with hidden dangers of waterlogging in a timely manner.

Monitoring center platform: The software platform is responsible for remotely monitoring real-time data such as air rainfall, surface runoff, and drainage pipe network confluence in key areas. Based on platform data and pipe network distribution information, the functions of waterlogging monitoring, inundation analysis and ponding water level prediction are realized through distributed hydrological models. The monitoring center software platform can display and process the graphical data through the large screen, PC, and mobile terminal, and at the same time store the data in the database to achieve permanent storage of the data.
