Urban Waterlogging monitoring system

Urban Waterlogging monitoring system has embedded ultrasonic water level, conductivity and flooding sensors to accurately monitor water accumulation in real time.Urban Waterlogging monitoring system equipment composition: The underground water measuring point is composed of a waterproof and anti-corrosion 304 stainless steel shell, a water level detection module (water depth, water status), a Bluetooth configuration module, a LORA wireless communication module, a built-in lithium battery, etc.

The working principle of the Urban Waterlogging monitoring system: Based on the liquid-mediated ultrasonic sensor, the time interval from emission to reception of the sound wave is measured, and the distance of sound wave transmission is obtained by combining the compensated sound speed of the sound wave. The current liquid level can be obtained based on the time difference from when the installed measuring point transmits the ultrasonic wave to when it receives the echo from the water surface.

Power supply method: built-in battery power supply (3.6V lithium sub-battery 38000mAH)

Battery life: without water accumulation, it can work continuously for more than 5 years (upload one message in 5 minutes without water accumulation, upload one message in 1 minute with water accumulation)

Water level range: ≤1.5m

Water level error: 1cm

Resolution: 1mm

Output signal: LORA wireless spread spectrum signal

Shell material: 304 stainless steel

Protection level: IP68

Urban Waterlogging monitoring system installation method: underground installation method is adopted, and an installation hole is opened at the road installation equipment. The equipment dimensions are as shown in the figure below. After the hole is opened, place the device vertically into the installation hole, pour filler into it, and secure the device. Note: Make sure the top remains level so as not to affect the measurement.

Equipment size: height 187mm, cavity diameter 60mm, top disk diameter 120mm.

Communication interface: Adopts LORA wireless communication, a low-power LAN wireless standard developed by semtech. This communication method achieves the unification of low power consumption and long distance. Paired with our company's unique LORA wireless communication protocol, it can communicate with our company's Sekisui Monitoring Station host computer wirelessly over long distances, with a communication line-of-sight up to 800m.

Configuration method: The mobile APP configures the device through Bluetooth wireless link.
