[0022] Ecological discharge monitoring should set up monitoring points at each discharge outlet of the power station. It is also possible to select a river section near the downstream of the power station dam site as a monitoring section, install a flow measuring device, and monitor the discharge flow. The ecological discharge flow monitoring sections of different types of hydropower stations should be arranged according to the following principles: 1. The monitoring section of the diversion hydropower station is arranged in the downstream of the reservoir dam in front of the powerhouse; 2. The monitoring section of the hybrid hydropower station is arranged in the downstream of the reservoir dam in front of the powerhouse; 3. The monitoring section of the dam-type hydropower station is arranged downstream of the reservoir dam or downstream of the tailwater of the power plant; 4. If there is a tributary or other source of water replenishment between the dam or power generation tailwater outlet and the monitoring section, the monitoring section should be arranged upstream of the tributary or other source of water replenishment inlet.

[0023] Since the flow rate of the on-site outlet is small when it is discharged and the transportation is inconvenient in the mountainous area, the trough and weir type requires concrete pouring and is difficult to construct. The flat gate flow calculation formula in the flow measurement of hydraulic structures can be used for calculation (only the gate level meter and water level meter need to be installed).

[0024] Principle and brief description of radar water level meter: SCJ-LD40 radar water level meter uses the principle of sound wave reflection to measure water level. The radar water level meter emits electromagnetic waves, which are reflected back when encountering the measured liquid level surface. The reflected echo is received and converted into an electrical signal. The water level meter measures the time difference T between the emission and reception of electromagnetic waves, as well as the propagation velocity constant C in the air. The distance between the water level meter and the liquid surface is calculated by the formula L1= CxT / 2, and the output water level value H=L1-L2 (L1 is the height from the bottom of the channel or pipe to the water level meter, referred to as the installation height of the radar water level meter).

[0025] The flow rate can be calculated using the formula Q=unbe, where u is the free hole flow coefficient, n is the number of gate holes, and e is the valve opening height. Ultrasonic water level meters are installed in front of the discharge gate on site, and gate level meters are installed on the gate to measure the gate opening. The flow rate is calculated according to the flow measurement specifications for hydraulic structures and weirs, and the flow measurement error of the quasi-section velocity field method is less than 8%. Based on the UE+Cesium technology system, DEM (better than 10 meters) and DOM data are used to quickly establish the twin scene base, and the cross-section and equipment models are established in the scene through manual modeling and provide data-driven interfaces. The basic business framework integrates model algorithms, and the digital twin scene realizes end-cloud collaboration in the form of pixel streams, using data to drive the three-dimensional scene.

[0026] The sensor data collected by the telemetry terminal can be sent to the server, mainly used to display the water level, flow rate, flow rate and other information of each site. The monitoring system application software adopts a hierarchical structure and modular design, and is mainly composed of information collection, comprehensive information services, system management and other parts.

[0027] During information collection, the water level, flow rate, flow, rainfall, pictures and other data or meteorological data of all measuring stations are received in real time, the information is decoded and the correctness of the telemetry data is analyzed, and various data are stored in the database in different categories. According to the working conditions and data of the measuring station collection equipment, the working conditions of the measuring station are analyzed, the system operation status is monitored, and the working parameters of the measuring station are modified remotely. The timed self-reporting time period of the measuring station and the reported values ​​of water level, flow rate, flow, rainfall and other data are reasonably arranged. The parameters that can be modified on-site at the telemetry station can also be modified remotely, providing local query and statistical management functions, including real-time data, hourly data, water situation reports, measuring station working conditions, communication accessibility rate, etc.

[0028] The comprehensive information service adopts B / S architecture and realizes the following functions through GIS map display: water level monitoring, automatically refreshing and displaying the latest or specified water level monitoring data based on the background graphics, and alerting the stations with abnormal conditions with special colors; flow monitoring, automatically refreshing and displaying the latest or specified flow monitoring data based on the background graphics, and displaying different water quality categories with different colors; system operation status monitoring, displaying the operation status of each telemetry station based on the background graphics, including whether the voltage and working status are normal, etc., and SMS alarms can be set for the information of the person in charge of the monitoring point.

[0029] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
