Urban Waterlogging monitoring system

Urban Waterlogging monitoring system collects water level data information in low-lying areas, such as urban underground parking lots, subway stations, bridges and other places.Urban Waterlogging monitoring system equipment consists of an underground waterlogging measurement point consists of a waterproof and corrosion-resistant 304 stainless steel shell, water level detection module (waterlogging depth, waterlogging state), Bluetooth configuration module, LORA wireless communication module, built-in lithium sub-battery, etc.

Urban Waterlogging monitoring system working principle: According to the liquid-intermediated ultrasonic sensor, the time interval between sound waves from transmission to reception is measured, and the compensation sound speed is combined to obtain the distance of sound wave transmission. The current liquid level height can be obtained based on the time difference between the time difference between the emission of ultrasonic waves and the reception of water surface echoes.

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

Battery life: If there is no water accumulation, you can work continuously for more than 5 years (upload one for 5 minutes without water accumulation, and upload one for 1 minute after water accumulation)

Water level range: ≤1.5m

Water level error: 1cm

Resolution: 1mm

Output signal: LORA wireless spread spectrum signal

Housing material: 304 stainless steel

Protection level: IP68

Urban Waterlogging monitoring system installation method: Adopt an underground installation method, and an installation hole is opened at the pavement installation equipment. The equipment size is shown in the figure below. After the opening is completed, place the equipment vertically into the installation hole, pour the filling into the fixing device. Note: Make sure the top remains horizontal so as not to affect the measurement.

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

Communication interface: LORA wireless communication, a low-power LAN wireless standard developed by semtech, is adopted. This communication method realizes the unity of low power consumption and long-distance. We use our company's unique LORA wireless communication protocol to communicate with our company's water monitoring station host for wireless long-distance communication, and the communication range can reach 800m.

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