Ecological Flow Monitoring System Platform

Monitoring equipment

To comprehensively implement Xi Jinping’s Thought on Ecological Civilization and the important expositions of General Secretary Xi Jinping on water management, we will actively put into practice the guiding principles of “water conservation first, spatial balance, systematic governance, and dual‑pronged efforts.” Closely adhering to the overarching tone of water‑related reform—“addressing shortcomings in water infrastructure and strengthening regulatory oversight in the water sector”—and with the goal of safeguarding the ecological functions of rivers and lakes, we will scientifically determine ecological flow targets, rigorously manage ecological flows, enhance monitoring and early warning systems for ecological flows, and accelerate the establishment of a robust framework for setting and ensuring ecological flows that features clear objectives, well‑defined responsibilities, strong safeguards, and effective oversight. In doing so, we will promptly address pressing issues of aquatic ecological damage and continuously improve the ecological environment of rivers and lakes.

Ecological flow in rivers and lakes refers to the flow rate (volume and water level) and its temporal dynamics that must be maintained within these water bodies to sustain the structure and functions of their aquatic ecosystems, while meeting water quality standards. By strengthening the management of water allocation and regulation for rivers, lakes, and reservoirs, this approach ensures that basic ecological water needs are met, preserves the river’s self‑purification and dilution capacity, and prevents water pollution caused by drastic changes in flow volume or flow patterns. The system monitors water levels, discharge, rainfall, and water quality in rivers, lakes, and reservoirs, providing real‑time monitoring and early warning to define and safeguard ecological flows, thereby supporting efforts to improve the ecological environment of these water bodies. 　　

Ecological Flow Monitoring System Platform

The system comprises a power supply, a telemetry terminal, cameras, a current meter, a rain gauge, an LED display, and other components. The telemetry terminal is the system’s core unit, featuring multiple RS‑232, RS‑485, single‑wire bus, and digital I/O interfaces, and can be connected to external devices such as pressure‑type water level sensors, float‑type water level sensors, radar water level sensors, electronic water gauges, current meters, rain gauges, water quality sensors, and cameras. It can be powered either by solar energy or by grid electricity.

Bluetooth debugging functionality: The telemetry terminal is equipped with a built-in Bluetooth communication module, enabling system debugging and configuration directly via a smartphone.

Anti-theft Alert: Both the telemetry terminal host and the sensors are equipped with built-in attitude sensors. When the device is moved or tampered with, the system activates the camera to capture an image and sends an alert notification to the operations and maintenance platform.

Instrumentation and Operations Platform: Enables remote modification of device configuration parameters and firmware upgrades, among other functions.

Cross-sectional water quality monitoring

The buoy station comprises a buoy body and anchor system, water-quality sensors (measuring temperature, dissolved oxygen, turbidity, conductivity, pH, ammonia nitrogen, UVCOD, chlorophyll, etc.), a data‑acquisition module, a wireless communication module, a solar‑power supply system, warning lights, a GPS positioning system, and a water‑quality monitoring cloud platform. It requires no cable installation and can be quickly and easily deployed at locations needing monitoring to provide continuous water‑quality surveillance.

The MXT06 water quality monitoring station can be equipped with a variety of water-quality sensors, including UV‑based organic matter analyzers, ammonia‑nitrogen sensors, and others. This buoy‑mounted system integrates sensor technology, solar‑power supply, and IoT communication, enabling round‑the‑clock, continuous, fixed‑point monitoring of water quality while transmitting data to the monitoring platform in real time.

The control system draws the water sample to be tested via a pump, passes it through coarse filtration, and then directs it to a storage tank for measurement. It supports monitoring of parameters including dissolved oxygen, pH, ORP, electrical conductivity, turbidity, COD, ammonia nitrogen, and chlorophyll. The host unit collects and processes data from various digital sensors via an RS‑485 (Modbus/RTU) bus, and transmits this data to a touch-screen display. The control module also features data transmission capabilities: through its RS‑485 interface, it can report monitoring results and instrument status to a supervisory computer, PLC, or other higher-level systems; alternatively, it can send data to a cloud platform via 4G or NB‑IoT networks.
