IOT News

Entering the "15th Five-Year Plan" period, China has begun systematically advancing the planning and construction of six major networks: water networks, new-generation power grids, computing power networks, next-generation communication networks, urban underground pipe networks, and logistics networks. Among these, the integrated monitoring and sensing system is also being accelerated, enabling one-click, cross-basin precision water allocation and achieving refined, smart water governance.

Traditional monitoring methods are often constrained by challenges such as lack of utility power at remote sites, poor communication conditions, and heterogeneous data protocols, making it difficult to meet the real-time data demands of digital twin water network platforms for the "forecast, early warning, pre-simulation, and contingency planning" functions. There is an urgent need for more reliable and intelligent data collection and communication solutions. The hydrology and water resources gateway RTU introduced by WideIOT integrates low-power design, multi-protocol data acquisition, 5G/4G/LoRa and other wireless communication technologies, and an embedded management platform, providing stable and reliable technical support for hydrological and water resources data collection and compliant reporting.

The gateway supports connectivity to water level gauges, flow meters, water quality sensors, rain gauges, pumping station PLCs, gate PLCs, cameras, and other devices. Through RS485, RS232, Ethernet, and other interfaces, it collects multi-source data in real time—including water level, flow rate, flow velocity, water quality, and equipment operating status—and transmits it via protocols such as HJ212, SL651, SL427, SZY206, MQTT, and Modbus over 5G/4G networks to the digital twin water network platform, providing a high-fidelity data foundation for water network situational awareness and model-based simulations.

The device features low-power design, wide-temperature compatibility, wide-voltage input, and both hardware and software watchdogs. It supports solar/battery power supply, making it suitable for remote hydrology stations without utility power. Additionally, it incorporates built-in encryption algorithms, enabling secure integration with hydrology and water resources management authority platforms or mainstream IoT platforms such as Huawei, Alibaba, and Baidu, ensuring end-to-end data security throughout the entire chain from collection to application.

Application Scenarios

1. River and Lake Monitoring Stations

Deployed at monitoring sites along rivers, lakes, and ponds, the hydrology gateway RTU collects real-time data on water level, flow velocity, and flow rate, providing high-frequency, high-precision hydrological data inputs to the platform. This supports flood evolution simulation, inundation range pre-simulation, and other "four-pre" functions, facilitating smart decision-making for basin-wide flood control.

2. Reservoir Safety Monitoring

Connected to piezometers, displacement meters, water level gauges, and rain gauge stations at reservoir dams, the system enables round-the-clock automated monitoring and data reporting of reservoir engineering conditions and rainfall-water conditions. When monitored values exceed thresholds, the system automatically triggers alerts and pushes notifications to responsible personnel, providing real-time data support for reservoir safe operation and dispatch contingency planning.

3. Gate and Pump Station Remote Control

By interfacing with gate PLCs, pumping station PLCs, and flow meters, the system enables two-way communication—reporting gate and pump operation data upward and receiving dispatch commands downward. This achieves dynamic water resource monitoring and precise dispatch across rivers, irrigation districts, and other scenarios, forming a closed-loop management cycle of "monitoring—simulation—dispatch—feedback."
