Waterlogging Monitor: Empowering Smart City Drainage with Real-time Data

Waterlogging monitors are usually installed in areas of the city that are prone to waterlogging, such as low-lying areas, underground passages, and under overpasses. It acts as a "data collector", using high-precision water level sensors and other equipment to accurately collect key data such as the depth of waterlogging and the rate of water level change, and transmit it to the monitoring center in real time. Some monitors can also monitor information such as water flow speed and water quality, comprehensively considering the overall situation of waterlogging.

Based on these real-time data, the waterlogging monitor can quickly trigger a warning mechanism when the waterlogging depth reaches the preset warning value. The warning information will be widely disseminated through multiple channels such as text messages, mobile app push notifications, and electronic display screens. The traffic management department uses roadside electronic display screens to inform passing vehicles of the details of waterlogging and road conditions ahead in a timely manner, helping drivers plan their routes rationally. The emergency management department sends text messages to inform nearby residents to take preventive measures in advance, such as moving vehicles and protecting basements.

The long-term accumulated monitoring data can be used to deeply analyze the effectiveness of the drainage systems in different areas. For example, the length of time it takes for waterlogging to subside is used to evaluate whether the diameter of the drainage pipes and the power of the pumping stations are suitable, and accurately locate drainage bottlenecks. During rainfall, the monitoring data is integrated into the drainage dispatching system to intelligently control the start and stop of drainage pumping stations and the opening of valves. When the waterlogging in a certain area rises suddenly, the drainage capacity of the nearby pumping stations is preferentially enhanced to accelerate the drainage of waterlogging.

Moreover, the analysis of data from multiple rainfalls can accurately identify areas prone to waterlogging and draw a waterlogging risk map, providing directions for the long-term planning of the city.

These data are also the key basis for infrastructure renovation. Whether it is the renewal of drainage pipes, road expansion, or the construction of new urban areas, they can be used to avoid the recurrence of waterlogging risks, helping the city to build a more scientific and efficient drainage system and relieve waterlogging pressure.
