2. Smart drainage network precise monitoring solution, guarding the underground "lifeline" of the city

The intelligent drainage network precise monitoring solution achieves real-time perception, risk warning and scientific scheduling of the drainage network operation status through the "perception analysis decision" full chain system, relying on high-precision monitoring equipment and intelligent management platform, effectively guarding the underground "lifeline" of the city.

1. Core monitoring equipment: Accurate perception, adaptable to complex environments. Advantages of Doppler ultrasonic flowmeter technology: Based on the Doppler effect, it can monitor the f

low velocity and flow rate in real-time under full/non full pipe conditions, with an accuracy of ± 1.5% and a data fluctuation rate of<3%.

. Titanium alloy sensors are corrosion-resistant, have no mechanical components, and have a lifespan of over 10 years; Built in adaptive filtering algorithm, resistant to interference from suspended solids and bubbles. Installation points: The length of the straight pipe section should be at least 10 times the diameter of the pipe, avoiding bends and valves; The sensor forms an angle of ± 5 ° with the pipeline axis, and surface attachments are cleaned every 3 months. Application case: 20 devices were deployed in Qingshan District, Wuhan City to accurately identify rainwater and sewage mixing points, reducing COD emissions by over 15 tons within six months. Advantages of radar flowmeter technology: Non contact measurement of 24GHz high-frequency radar waves, maximum monitoring distance of 40 meters, suitable for open channels and box culverts; The AI algorithm filters out interference from rain, snow, and floating objects, with a water level accuracy of ± 2mm and a flow velocity accuracy of ± 0.03m/s. IP68 protection, wide temperature operation from -40 ℃ to 80 ℃, supports solar power supply. Installation points: The installation height should be 0.3-0.5 meters above the water surface, away from strong electromagnetic interference sources (such as high-voltage lines). Actual test effect: The false alarm rate of the Chengdu High tech Zone project is less than 0.5%, which replaces the traditional weir and trough measurement and reduces construction costs by 60%. Advantages of radar water level gauge technology: 80GHz high-frequency radar beam angle of 3 °, anti condensation interferen
