1Urban waterlogging monitoring and early warning systemProduct Introduction
The buried urban waterlogging monitoring system is supported by Internet of Things technology and integrates intelligent sensing and intelligent services into an intelligent monitoring system.
The system consists of a monitoring host, pole support, power supply system, buried water accumulation monitoring device, LED dual color display screen, and cloud platform. It mainly provides real-time monitoring and early warning services for urban roads, ground, tunnels, overpasses and other places that are prone to water accumulation.
The system adopts highly integrated integrated water accumulation monitoring equipment to monitor the water level in low-lying sections of the urban area in real time and achieve automatic alarm. By integrating data from various monitoring points, it can grasp the overall water accumulation situation in the urban area and timely carry out drainage scheduling. With the help of this system, the municipal administration departments can achieve regular monitoring, early warning and early preparation, deal with the places where floods may occur due to rainstorm, reduce the probability of urban salvage, and at the same time, do a good job of early warning for the people in the areas where water level rises. The traffic management department can obtain real-time water levels of various road sections through this system, and provide travel guides for the general public through media such as radio and television, avoiding personnel and vehicles from entering deep water sections, reducing economic losses for the public, and ensuring their personal safety.

IIUrban waterlogging monitoring and early warning systemScope of application
It can be applied to urban management, municipal transportation roads, residential areas, low-lying areas, underground parking lots, logistics parks, agricultural irrigation areas, tourist attractions, and can also be used for smart city construction.
