Ministry of Water Resources The Ministry of Ecology and Environment jointly issued the "Notice on Strengthening the Ecological Flow Supervision of Small Hydropower Stations in the Yangtze River Economic Belt" (Hydropower [2019]241), the General Office of the Ministry of Water Resources issued the "Notice on the Technical Guidance of the Ecological Flow Supervision Platform for Small Hydropower Stations" (Letter of Water and Electricity Office[2019]1378) and other documents, requiring provinces and cities to carry out ecological flow of hydropower plants span>“one stop One strategy”Program preparation, determine the ecological flow discharge plan of each hydropower station, and at the same time, each province and city should establish and improve the ecological flow supervision platform of hydropower stations to ensure that monitoring data (images) are received in a timely and accurate manner to meet the needs of ecological flow supervision. Be

   Shenzhen GuodianGDST-1The ecological flow monitoring device supports flow data monitoring, image and video monitoring at the same time, and is used to monitor the flow and process required by the downstream river channel of the barrage facility of the small hydropower station to meet the ecological protection requirements and maintain the basic structure and function of the ecosystem .And real-time monitoring of flow data, providing real-time scenes, and recording video and taking pictures as required, using character video overlay technology, the display is clear at a glance. It has real-time monitoring of flow, water level, etc. through flow monitoring sensors and video,Overlay measured data and photo video storage and Regularly upload data to the provincial platform or environmental supervision platform, and automatically adjust the function of leaking flow. A variety of monitoring methods are suitable for different types of hydropower stations: pipeline discharge type, channel discharge type, gate opening type discharge type, manual pumping type discharge type, unit power conversion discharge type, etc. This flow monitoring system supports the communication protocols and requirements of various provinces, and can also be customized and developed for new needs.

   Shenzhen GuodianGDST-1 Ecological Flow Monitoring Device span>with matching18 Road I/OAlternate port,4Road measurement spare port. It has a long-term perspective to evaluate other related actual needs of hydropower stations, and achieves multiple benefits with the same cost. Therefore, Shenzhen Guodian mainframe also has functions such as expanding smart water conservancy informatization: water level monitoring, flow monitoring, water quality monitoring, reservoir monitoring, large Dam safety monitoring, rainfall monitoring, dam gate control, safety alarm, early warning, remote/close-to-control gate, for water conservancy informatization monitoring and hydropower station remote gate control, etc. The functions of the device are more prepared to avoid unnecessary repeated investment in the future development of the era, and only a small part of the cost of accessories can be incurred.

Main Features

◆Real-time monitoring of the water level of the water intake of the hydropower station, reasonable arrangement of power generation, and improvement of the utilization rate of water resources;

◆Real-time monitoring of the flow of the ecological flow discharge outlet to ensure the ecological environment balance of the river downstream of the water intake;

◆Generate data reports for easy analysis and reasonable arrangement, so that production and ecology are better guaranteed;

◆The perfect alarm function makes the power generation of the power station safer.
