Smart Water Conservancy: Building a Digital Water Management System

Definition and Background of Smart Water Conservancy

With the rapid development of information technology and increasingly complex challenges in water resource management, traditional water conservancy management models can no longer meet the needs of modern society. Against this backdrop, Smart Water Conservancy has emerged as the higher stage of water conservancy informatization construction.

What is Smart Water Conservancy?

Smart Water Conservancy leverages advanced technologies such as the Internet, cloud computing, big data, and geographic information systems (GIS) to pursue the core goals of “digitization, networking, visualization, and intelligence,” transforming water conservancy operations from traditional modes to intelligent decision-making and services.

In short, Smart Water Conservancy establishes a comprehensive, full-process, full-business intelligent water management system, achieving more thorough, flexible, and efficient interconnection and mutual perception among objects, between objects and people, and among people within the water conservancy sector.

Core Objectives and Capability Enhancements of Smart Water Conservancy

The essence of Smart Water Conservancy lies in achieving the following key capability improvements:

Comprehensive perception and interconnection: Enhancing interconnectivity and mutual awareness of various water engineering facilities and hydrological elements.
Information processing and resource integration: Building efficient and secure platforms for information processing and water resource integration.
Scientific decision-making and early warning: Enabling more scientific monitoring, forecasting, analysis, prediction, and decision-making, especially in flood control and drought resistance.
Intelligent execution: Improving remote control and intelligent operation of water facilities (e.g., automatic opening/closing of sluice gates and pump stations).
Cross-departmental collaboration: Promoting coordinated cooperation across departments, levels, and locations in water conservancy operations.

System Architecture and Monitoring Elements of Smart Water Conservancy

The Smart Water Conservancy system is a complex integrated entity that tightly combines front-end sensing devices, transmission networks, and back-end management platforms to form an efficient closed-loop operation.

Components of System Monitoring Elements

Hydrological monitoring activities typically consist of the following four major parts:

Measurement equipment (front-end perception): The system’s “eyes,” including rain gauges, water level gauges, flow meters, water quality instruments, etc., used for real-time collection of on-site hydrological and water quality parameters.
Front-end monitoring terminal (RTU): Also known as hydrological remote terminal unit, responsible for real-time signal acquisition from measurement devices and preliminary data processing according to hydrological communication protocols.
Communication network (transmission channel): Including GPRS/LoRa/4G/5G, public Internet, etc., ensuring real-time and reliable transmission of collected data to the monitoring center.
Monitoring center (platform brain): Composed of servers, dedicated lines, and hydrological monitoring system software, responsible for real-time data display, storage, professional analysis, warning issuance, and remote control.

Key Monitoring Contents of Smart Water Conservancy

By integrating multi-source data, the Smart Water Conservancy system achieves comprehensive monitoring of the following key information:

1. Integrated Meteorological and Hydrological Monitoring
Rainfall and meteorology: Integrating meteorological stations and weather radar data to comprehensively monitor precipitation, evaporation, runoff, etc., supporting disaster weather warnings and hydrological forecasting.

2. Water Regime and Hydrological Information Monitoring
Water body status: Using GIS technology to visually display the location, scope, and condition of rivers, lakes, reservoirs, and groundwater.
Core parameters: Real-time monitoring of river water levels, flow velocity, discharge, reservoir water levels, etc. Combined with professional models for multi-dimensional analysis and prediction of water regime parameters such as flow, velocity, rainfall (snow), and evaporation.

3. Water Quality and Sediment Monitoring
Water quality safety: Real-time monitoring of pH, dissolved oxygen, ammonia nitrogen, turbidity, and other water quality indicators to ensure water supply safety and water body health.
Sediment changes: Monitoring sediment content in rivers or reservoirs to provide data support for reservoir capacity changes and riverbed scouring/silting dynamics.

NiuBoL: Key Sensing Equipment for Smart Water Conservancy

As a professional manufacturer in the field of IoT sensors, NiuBoL Technology focuses on the core of water level monitoring — measurement equipment — and combines advanced communication technologies to provide highly reliable, high-precision front-end sensing devices and systems for Smart Water Conservancy.

Core Sensing Products for Smart Water Conservancy

NiuBoL’s online hydrological monitoring system can be applied to natural rivers, reservoirs, channels, groundwater, etc., covering monitoring of water level, rainfall/snow, flow, velocity, etc.

1. Radar Level Gauge (Non-contact Water Level Monitoring)
Principle: The antenna emits extremely narrow microwave pulses that are reflected back upon hitting the water surface. The water level is accurately calculated by measuring the time interval between transmission and reception, thus determining the distance from the antenna to the water surface.
Advantages: Non-contact measurement, unaffected by water quality, temperature, or sediment; high accuracy, simple maintenance, avoiding the damage-prone issues of traditional contact-type equipment.

2. NBL-W-RS Tipping-Bucket Rain Gauge
Principle: Uses the tipping-bucket counting principle to convert collected rainfall into pulse outputs according to a standard volume.
Application: Widely used in meteorological stations, hydrological stations, agriculture, forestry, and national defense, providing reliable raw rainfall data for flood warning, water supply systems, and reservoir management.

3. Submersible Level Transmitter
Principle: Utilizes a diffused silicon pressure sensor to determine liquid level by measuring the hydrostatic pressure generated by water depth. Special cables with atmospheric vents ensure water tightness and measurement accuracy.
Advantages: Suitable for reservoirs, groundwater, and other static or deep-water environments, delivering accurate and stable measurement data.

Features of NiuBoL Hydrological Monitoring System

NiuBoL’s online hydrological monitoring system offers the following distinctive practical features:

Strong functional scalability: Real-time water level monitoring with flexible expansion to rainfall, water quality, flow velocity, and other parameters.
Alarm and early warning: Supports immediate alarms for water level exceedance, sensor failure, or low terminal battery voltage.
Intelligent linkage: Can link with drainage pumping stations to automatically control pump start/stop based on river water level, achieving intelligent execution.
Remote visualization: Supports remote photo or real-time video monitoring (depending on communication method), helping managers grasp on-site conditions instantly.
