Relying on IoT communication technologies, the system enables real-time data collection, edge computing, cloud-based analysis and intelligent early warning, providing accurate decision support for reservoir operation, flood control and disaster mitigation, as well as water resources management. As an innovative enterprise in the field of water conservancy IoT, Xiamen Haichuan Runze IoT Technology Co., Ltd. has a product line covering core devices including RTUs, radar flow meters and bubbler water level gauges, forming a complete solution from data collection to intelligent analysis.
I. System Architecture: A Collaborative Hierarchical Perception Network
The water conservancy IoT monitoring system adopts a three-tier "terminal-edge-cloud" architecture to realize closed-loop management of the entire process from data collection to intelligent decision-making:
Terminal Layer
Deploy sensors such as RTUs, flow meters, water level gauges and rainfall gauges to form the "nerve endings" of data collection. As the core data hub, RTUs support the access of multiple types of sensors to achieve data aggregation and preprocessing; flow meters and water level gauges are responsible for the accurate measurement of flow velocity/flow rate and water level height respectively.
Edge Layer
Deploy edge computing devices at nodes close to data sources, such as sluice stations and pumping stations, to clean, detect anomalies and conduct preliminary analysis of raw data. For example, RTUs can perform filtering processing on osmometer data to remove invalid data; flow meters can calculate real-time instantaneous flow combined with cross-sectional morphology, reducing the computing pressure on the cloud.
Cloud Layer
Store massive monitoring data through cloud computing platforms, and utilize big data analysis and AI algorithms to implement advanced applications such as flood forecasting, water quality assessment and engineering safety early warning. The platform supports multi-dimensional data visualization, such as water level-flow hydrographs and engineering safety risk heat maps, providing managers with intuitive decision-making basis.
II. Core Devices: Functional and Technological Innovations
(1) Remote Terminal Unit (RTU): Intelligent Upgrade of the Data Hub
The HC-TX90S series RTU of Haichuan Runze serves as the data hub of the system, with the following core functions:
Multi-protocol Compatibility and Multi-sensor Fusion
It supports water conservancy industry protocols such as Modbus RTU/TCP, IEC 60870-5-104 and SL/T427-2021, and can connect to vibrating wire osmometers, tipping bucket rainfall gauges, ultrasonic water level gauges and other devices simultaneously to achieve "one-machine multi-measurement". For example, in mountain reservoir monitoring, RTUs can collect water level, rainfall and osmotic pressure data synchronously and transmit them to the cloud via 4G/Beidou dual links.
Edge Computing and Intelligent Early Warning
Built-in low-power MCU supports local preprocessing of data. For example, it performs real-time filtering on seepage data and cumulative statistics on rainfall data; when the water level exceeds the threshold, the RTU can trigger local sound and light alarms, and push early warning information via SMS and APP to realize "terminal-side autonomous decision-making".
Industrial-grade Protection and Low-power Design
Adopting an IP67 protection grade housing, it can adapt to environments ranging from -40℃ to +85℃; it supports solar power supply with standby power consumption below 1.5W, meeting the needs of unattended scenarios. For example, in reservoir monitoring in arid areas of Northwest China, RTUs can operate continuously for more than 3 years relying on solar panels.
(2) Radar Flow Meter: Technological Breakthrough in Non-contact Measurement
The HCRZ-LL100 radar flow meter of Haichuan Runze is based on the 24GHz Doppler effect to achieve integrated monitoring of water level, flow velocity and flow rate. Its technological innovations include:
Non-contact Measurement
Based on the microwave reflection principle, it can measure flow velocity without contacting water bodies, avoiding measurement errors caused by sediment deposition and corrosion of traditional current meters. For example, in the high sediment concentration waters of the Yellow River, the radar flow meter can stably obtain flow velocity data with an error rate of less than 3%.
High Precision and Anti-interference Ability
Adopting planar radar Doppler technology, it features a small beam angle, concentrated energy and strong anti-interference capability; it has a small blind zone, short wavelength and low transmission power, which is harmless to humans and the environment. For example, in urban waterlogging monitoring, radar flow meters can be installed under bridges to accurately capture instantaneous flow changes.
Low Power Consumption and Easy Installation
It supports two modes: command collection and interval collection, with power consumption below 2W; it is compact in appearance and easy to install, eliminating the need for well construction and can be directly fixed on river banks or sluices. For example, in irrigation channel monitoring, radar flow meters can be deployed quickly, reducing construction costs.
(3) Bubbler Water Level Gauge: Balance Between High Precision and Maintenance-free Operation
The HC-QPSW10-S bubbler water level gauge of Haichuan Runze measures water level through the gas pressure conduction principle, with the following core advantages:
Maintenance-free Design
No gas cylinders or measuring wells are required; a closed air chamber is formed through a built-in air pump and one-way valve, reducing external interference. For example, in flowing water monitoring, bubbler water level gauges can avoid measurement deviations of traditional float-type water level gauges caused by water flow impact.
High Precision and Adaptive Calibration
Integrated with pressure relief calibration function, it can automatically correct measurement errors regularly; it supports full temperature compensation and linear compensation to adapt to different water quality densities. For example, in reservoir monitoring in coastal areas, bubbler water level gauges can automatically adjust parameters to adapt to the mixed environment of seawater and freshwater.
Optimized Human-machine Interaction
Equipped with a 4.3-inch color touch screen, it supports free setting of zero point and base elevation; it provides a Modbus RTU protocol interface, compatible with mainstream RTU devices on the market. For example, in groundwater monitoring, bubbler water level gauges can seamlessly connect with RTUs to realize automatic data upload.
III. Data Transmission: A Full-scenario Communication Solution
The water conservancy IoT monitoring system needs to adapt to complex geographical environments, and Haichuan Runze provides a multi-mode communication solution:
4G/5G Communication
Suitable for areas with good signal coverage, it supports high-speed data transmission to meet the needs of video surveillance and real-time early warning. For example, in urban flood control and drainage monitoring, RTUs can upload real-time water level videos of low-lying road sections to the cloud via 4G networks.
Beidou Short Message
For remote mountainous areas, uninhabited areas and other scenarios without public network coverage, Beidou short messages can realize regular data reporting. For example, in reservoir monitoring in the alpine canyon areas of Southwest China, RTUs can send water level and rainfall data through Beidou modules to ensure no information loss.
LoRa/NB-IoT
Suitable for low-power consumption and wide-coverage scenarios, such as agricultural irrigation channel monitoring. LoRa modules can realize device networking within a range of several kilometers, while NB-IoT supports the access of a large number of devices, reducing operation and maintenance costs.
IV. System Integration: Seamless Connection from Devices to Platforms
Haichuan Runze provides an integrated "hardware + software + platform" solution to achieve deep integration of devices and systems:
Device-level Integration
RTUs, flow meters, water level gauges and other devices adopt standardized interface design, supporting plug-and-play. For example, the HC-TX90S RTU can connect to radar flow meters and bubbler water level gauges simultaneously, and automatically identify device types through the Modbus protocol.
Platform-level Connection
The smart water conservancy cloud platform supports multi-protocol parsing and can be compatible with data from Haichuan Runze devices and sensors of other manufacturers. The platform provides functions such as data visualization, anomaly early warning and work order management. For example, when the reservoir water level exceeds the warning value, the platform can automatically generate work orders and push them to the operation and maintenance personnel's APP.

For example, in typhoon weather, RTUs can automatically switch to Beidou communication to ensure data continuity.
Accurate Measurement
Advanced algorithms are adopted in radar flow meters, bubbler water level gauges and other devices, with measurement error rates lower than the industry average; multi-sensor fusion technology further improves accuracy through data cross-validation. For example, in reservoir seepage monitoring, RTUs can collect osmometer and water level gauge data synchronously, and eliminate interference through correlation analysis.
Flexible Scalability
The system supports device addition/removal, parameter adjustment and function upgrading. For example, only water level and rainfall can be monitored in the initial deployment, and later functions such as water quality monitoring and video surveillance can be expanded without reconstructing the system architecture.
