Build a solid "smart defense line" for urban flood prevention. Aotai equipment and owners jointly protect urban safety

With the frequent occurrence of extreme weather, urban waterlogging has become a major hidden danger that threatens the safety of residents' lives and property and hinders the normal operation of the city. Waterlogging will not only cause traffic paralysis and damage to infrastructure, but also secondary disasters such as leakage and sewage backflow are more likely to cause serious safety accidents. Therefore, building an accurate and efficient waterlogging monitoring system is a necessary measure to improve the city's disaster prevention and mitigation capabilities and ensure the safety of people's livelihood. It is also the core link in promoting the construction of sponge cities, resilient cities and urban lifeline projects.

Among the many urban waterlogging monitoring equipment, the underground road waterlogging meter has become the most widely used monitoring equipment with its significant advantages. The underground road waterlogging meter installed by Fujian Aotai Automation Equipment Co., Ltd. is equipped with conductivity and ultrasonic composite sensing technology to achieve dual verification and accurate measurement of waterlogging data. Among them, the ultrasonic sensor emits high-frequency sound waves and uses the reflection time difference to accurately calculate the depth of waterlogging; the conductivity sensor monitors the conductive properties of the water body in real time and determines the coverage of waterlogging by analyzing the changes in water quality. The two technologies complement each other, which can not only quickly respond to water level rise and fall, but also effectively eliminate interference factors such as leaves and debris accumulation, greatly improving the reliability and stability of the data.

It is worth mentioning that the device also supports advanced configurations of conductivity, ultrasonic and static pressure three-mode sensing sensor integration. The newly added static pressure sensor can provide stable depth data in complex environments (such as rainstorms, rapids, freezing and severe cold) by sensing changes in water pressure and combining temperature compensation algorithms. The three sensing technologies work together to form a "multi-dimensional cross-verification" mechanism. Even if a single sensor fails temporarily due to environmental influences, other sensors can still ensure the continuity and accuracy of monitoring data, building a more solid data defense line for the urban waterlogging warning system.

In addition, the underground road surface water meter adopts an invisible installation design. The main body of the device is completely embedded in the ground, and only a very small-sized sensing probe is reserved to be flush with the ground, which does not affect the passage of pedestrians and vehicles, and hardly causes any damage to the urban landscape. In terms of power supply and transmission, the device uses built-in high-energy lithium battery power supply and wireless radio frequency transmission technology, combined with a low-power intelligent sleep wake-up mechanism, and the comprehensive battery life can reach more than 5 years, effectively reducing the frequency of manual inspections and improving the stability of the long-term operation of the monitoring system. This "hidden" monitoring solution is highly consistent with the construction concept of sponge cities, which is "ecological priority and natural infiltration". It can not only accurately capture the changes in road water levels in real time, but also take into account the beauty and coordination of the urban environment. It provides reliable data support for urban waterlogging warning and emergency dispatch, and effectively helps cities build a solid safety line and promote the intelligent upgrade and sustainable development of urban infrastructure.
