Yangtze River Daily, Wuhan, June 29 (Reporter Jin Wenbing) In the rainy season, a small column embedded in the "road teeth" (curb) on the side of the road can become a flood control sentinel with "wide eyes" in seconds. On June 29, a reporter from the Yangtze River Daily came to the Hankou Binjiangyuan Community and saw a circular column with a diameter of about 8 centimeters and the same height as the curb stone on the side of Yanjiang Avenue inlaid in the curb. If someone hadn't told me, it would have been hard to believe that this "little guy" was actually a weapon to prevent flooding.

Chen Song, assistant general manager of Wuhan Xinfeng Optoelectronics Co., Ltd., told reporters with a smile that this is an integrated waterlogging monitoring water level gauge (roadside type) innovatively developed by the company. "Don't look at the small size of this water monitor, there is a lot in the 'belly': it is equipped with a built-in lithium battery, which can last for 3 years, and it integrates and installs a variety of sensors such as radar, pressure, and water level detection. A small chip can help solve the big problem of urban water accumulation. ”
When there is no water on the road surface, it only needs to "wake up" at a set time every day and report "no water". The usual sprinkling of water on the road and sporadic rainfall will not easily alarm it.

Once the water on the road exceeds the set threshold, it will automatically turn on and transmit data to the background every 5 minutes; If the water depth is constantly changing, it uploads relevant data such as water depth and water temperature at intervals of 1 minute for the background commander to clearly grasp the decision.
Chen Song introduced that at present, more than 100 sets of water monitoring instruments have been installed in various key anti-stain points in Wuhan.
Recently, Wuhan ushered in the second heavy rainfall of this year's rainy season, and the city's drainage system was under great pressure. Wuhan is exploring the use of science and technology to replace manual investigation.
Three days ago, the Wuhan water affairs department also cooperated with Xinfeng Optoelectronics to urgently install a set of AI wading linkage language alarm system on the secondary hydrophilic platform of Sanyang Square on the Hankou River Beach.

This overhead video probe integrates multiple technologies such as artificial intelligence and the Internet of Things. The image recognition function is equivalent to setting up an "electronic fence" in the "field of view", once a resident exceeds the warning line and wades into the water, the system will automatically start the early warning broadcast, advise the resident to retreat to a safe area, and reduce the risk of drowning.
It is understood that the urban water system intelligent platform and subsystem that integrates cloud computing, big data, model simulation, digital twin, artificial intelligence, industrial Internet, information security, edge computing and other technologies - urban waterlogging monitoring and intelligent control and dispatching system, have been applied to the water system at the municipal and district levels in Wuhan.
The relevant person in charge said that "sensing-transmission-platform-application", through this front-end identification and early warning, back-end model analysis to give a disposal plan, all kinds of water conditions and other water situations converge on an "electronic combat map", Wuhan is using the above-mentioned "smart brain" to scientifically study and judge, scientific dispatch of urban water affairs, and realize water control and dispatch and operational command based on "one map".
