NiuBoL Rainfall Monitoring Station: Professional Rainfall Online Monitoring Solution for Water Conservancy Flood Control and Hydrological Measurement and Reporting

Description

Rainfall is a key meteorological parameter affecting flood control and drought resistance, agricultural production and infrastructure operation. NiuBoL rainfall monitoring station, as a modern rainfall observation device with IoT architecture, consists of high-precision tipping bucket rainfall sensor, data acquisition and transmission device, solar power supply system, stainless steel bracket and backend IoT platform. It can realize automatic statistics and wireless remote transmission of rainfall status, rainfall intensity and cumulative rainfall (single rainfall, daily rainfall, weekly rainfall, monthly rainfall, annual rainfall).

The system is produced in strict accordance with SL61-2003 hydrological automatic measurement and reporting system specifications, GB11831-89 and GB11832-89 tipping bucket rain gauge standards. It is suitable for deployment in water conservancy, hydrology, meteorology, flood control, agriculture and transportation projects by system integrators, IoT solution providers and engineering companies. NiuBoL rainfall monitoring station provides stable and reliable rainfall data collection capabilities for business partners with its low power consumption design, ultra-long standby capability and standardized communication interface, helping real-time water condition monitoring and scientific dispatching decision-making.

Core Significance of Rainfall Monitoring in Engineering Fields

Rainfall monitoring provides scientific basis for drought prevention and flood control and is an important component of hydrological automatic measurement and reporting systems. Real-time mastery of rainfall, rainfall intensity and rainfall start and end times can provide key data support for flood warning, water supply dispatching, power station reservoir operation management and highway airport safety assurance.

In the traditional manual observation mode, rainfall data has poor timeliness, limited coverage and is obviously limited by manpower. NiuBoL rainfall monitoring station realizes all-weather unattended automatic monitoring through IoT wireless transmission technology, significantly improving data continuity and transmission efficiency. When rainfall occurs, the device automatically wakes up and reports data at set intervals; when there is no rainfall, it enters low-power sleep mode, effectively extending equipment endurance.

The system can automatically count rainfall data on multiple time scales and supports direct export to Excel tables, providing reliable raw data for hydrological model calibration, flood forecasting and climate trend analysis.

System Composition of NiuBoL Rainfall Monitoring Station

NiuBoL rainfall monitoring station adopts a modular design and mainly consists of the following core parts:

• Rainfall sensor (rain gauge): the core measurement component, using tipping bucket structure, rain receiving diameter φ200mm, high precision and good linearity.

• Data acquisition and transmission device: integrated data processing unit and wireless communication module, supporting MQTT protocol and 4G remote transmission.

• Power supply system: solar panel (60W/100W optional) + high-capacity battery (30Ah/40Ah), supporting ultra-long standby.

• Installation bracket: 2-3 meter stainless steel or galvanized steel bracket, sturdy and corrosion-resistant, easy for field installation.

• IoT monitoring platform: supports multi-site management, real-time data viewing, historical record query, remote parameter setting and data export.

The whole equipment is compact in size and easy to install, suitable for decentralized deployment and rapid point layout.

Technical Principle and Functional Features of Rainfall Sensor

NiuBoL rainfall sensor (NBL-W-RS) is designed based on the tipping bucket working principle. Rainwater enters the rain gauge through the rain receiving port and collects into the tipping bucket. When the accumulated water in the tipping bucket reaches the set resolution (0.2mm), it automatically flips and triggers the reed switch signal to realize precipitation counting.

Main functional features:

• Small friction torque of tipping bucket support system, sensitive and reliable flipping

• Built-in filter circuit, effectively suppressing electromagnetic interference

• ABS material shell resistant to acid and alkali corrosion, small stagnant water error

• Base equipped with level adjustment bubble to ensure installation levelness

• Supports multiple output forms: switch signal, 0~5V voltage, RS485, 4-20mA

The sensor is produced in strict accordance with national standards and is suitable for remote measurement of liquid precipitation, precipitation intensity and precipitation start and end times. It can be directly connected to the hydrological automatic measurement and reporting system.

Core Advantages of NiuBoL Rainfall Monitoring Station

• Ultra-long standby capability: solar energy + large-capacity battery combination can achieve continuous operation for five years without battery replacement, significantly reducing maintenance frequency.

• Wireless remote monitoring: supports 4G/MQTT/HTTP protocols, real-time data upload to IoT platform, no wiring required, suitable for remote area deployment.

• Unattended operation: automatic wake-up and reporting when raining, automatic sleep when no rain, reducing operating costs.

• Intelligent data processing: automatic statistics of this rainfall, daily/weekly/monthly/annual cumulative rainfall, supports remote setting of reporting interval and parameters.

• Data reliability: automatic local caching when network is abnormal, batch retransmission after recovery; platform supports centralized management of multiple sites.

These advantages make NiuBoL rainfall monitoring station a high cost-performance rainfall data collection terminal in engineering projects.
