Urban Waterlogging monitoring system

Urban Waterlogging monitoring system is an urban waterlogging monitoring and early warning system based on the Internet of Things. It can collect data information on water level, flow and other low-lying areas.Urban Water logging monitoring system equipment composition: The underground water accumulation measurement point consists of a waterproof and corrosion-resistant 304 stainless steel shell, a water level detection module (water accumulation depth, water accumulation status), a Bluetooth configuration module, a LORA wireless communication module, a built-in lithium-ion battery, etc.

Working principle of Urban Waterlogging monitoring system: Based on the liquid-medium ultrasonic sensor, the time interval from the emission to the reception of the sound wave is measured, and the distance of the sound wave transmission is obtained by combining the compensated sound wave speed. According to the time difference from the emission of the ultrasonic wave to the reception of the water surface echo at the installed measuring point, the current liquid level height can be obtained.

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

Battery life: In the absence of water accumulation, it can work continuously for more than 5 years (upload one message every 5 minutes without water accumulation, and upload one message every 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 a mounting hole is opened at the road surface where the equipment is installed. The equipment size is shown in the figure below. After the hole is opened, put the equipment vertically into the mounting hole, pour the filler to fix the equipment. Note: Make sure the top is kept level to avoid affecting the measurement.

Equipment dimensions: height 187mm, cavity diameter 60mm, top disc diameter 120mm.

Communication interface: Adopting LORA wireless communication, a low-power LAN wireless standard developed by Semtech, this communication method realizes the unity of low power consumption and long distance. With our unique LORA wireless communication protocol, it can communicate with the host of our waterlogging monitoring station wirelessly over long distances, and the communication line of sight can reach 800m.

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