Solution - Ecological Flow Monitoring System for Hydropower Stations
Water conservancy IoT products andTechnologySolution provider
Online monitoring system for ecological discharge flow of small hydropower stations
What is ecological flow
Ecological flow refers to the minimum flow required to maintain the ecological water demand of rivers and lakes, while ensuring sufficient discharge of water during the power generation and agricultural water use process of hydropower stations, in order to avoid adverse effects on the downstream ecological environment, especially on aquatic organisms, and causing ecological problems.

Standards followed in scheme design
Notice of the General Office of the Ministry of Water Resources on Issuing the Technical Guidance for Ecological Flow Supervision Platform of Small Hydropower Stations (No. 1378, 2019)
Power station type: 50MW and below hydropower stations (regardless of dam type or diversion type);
Regulatory approach: Establish an ecological traffic monitoring platform, including backend monitoring software system, data transmission equipment (video telemetry terminal), and frontend monitoring equipment;
Installation location: downstream river sections of each discharge outlet and power station dam site;
Monitoring methods: video image monitoring (200W and above pixels), real-time traffic monitoring; Real time traffic data can be overlaid on the video;
Power supply mode: mains power or solar power;
Transmission standard: Data transmission: SZY206-2016 (water resources) or HJ/T 202-2017 (environmental protection)

System functions
Real time monitoring of ecological discharge flow
Real time collection of data from measuring and measuring instruments such as flow meters, water level gauges, and gate level gauges through IoT video telemetry terminals, and uploading the results to a designated platform center through built-in flow algorithms to achieve remote monitoring of data
Support exporting monitoring data through USB/TF card
Real time video transmission and storage of photos and short videos
Equipped with a 10M/100M Ethernet port, it can connect to a network camera and capture photos and short videos regularly. It also provides a wireless internet channel for the network camera to connect to the cloud platform (taking Hikvision as an example, it can connect to Yingshi Cloud and Hikvision Internet Platform)
Support exporting photos and short videos through USB/TF card
Video/image data character overlay, image browsing, status display
Configurable overlay character information, including:Hydropower station name, hydropower station code, approved flow rate, ecological flow rate, monitoring point water level, gate opening, flow velocity and other information
The touch screen displays the current connection status with the center, camera connection status, memory status, current time, power station name, parameters, and photos
You can browse photos on the touch screen and perform page flipping and other operations
Flexible and customizable features
Specially designed for ecological flow monitoring projects of hydropower stations, users only need to set variable parameters according to the characteristics of different provinces
The amount and name of collected data can be modified by oneself
You can overlay corresponding names and data by setting
The display data on the touch screen can be customized without the need for program updates
Local and remote maintenance functions
Cross platform use, no need for dedicated software or data cables
Connect the network cable to the computer and use web pages to set parameters
Support remote webpage parameter setting
Example: A photo of ecological flow in a certain area of Guangdong Province
Display interface of IoT video telemetry terminal
Wireless 4G/broadband adaptive internet access and integration with various provincial and municipal platforms
Communication method
The system supports 4G and broadband adaptive internet access, and platform connection can be achieved with simple configuration;
Supports FTP, HTTP (Json), TCP/IP, MQTT/MQTTS, Water Resources Monitoring Data Transmission Protocol (SZY206-2016), Pollution Source Online Automatic Monitoring (Monitoring) System Data Transmission Standard (HJ/T212-2017), supports custom protocol access
