[0054] S1, water level meter installation stage: two radar water level meters 203f (radar No. 1 and radar No. 2) and one pressure water level meter 203b (pressure type No. 1) are installed at predetermined key monitoring points in front of the trash rack 101c of the hydropower station dam, and two pressure water level meters 203b (pressure type No. 2 and pressure type No. 3) and one radar water level meter 203f (radar No. 3) are installed behind the trash rack 101c. The selection of these water level meters is based on their measurement accuracy and adaptability to environmental factors to ensure stable operation under subtropical mountain climate conditions. The installation position of the water level meter can be adjusted and fixed at will according to the device design to avoid the measurement dead zone caused by the limitation of the installation position. The water level meter collects the dam water level signal;

[0055] S2, data transmission and processing stage: the collected water level signals are processed and analyzed to obtain the calculated water level value; wherein, all water level meters are connected to the local control unit of the dam via cables, and the local control unit uses a three-average strategy to process the received water level data, that is, when all water level meters are working normally, the average value of the two radar water level meters 203f is taken as the control basis; if any radar water level meter 203f fails, the data of the other radar water level meter 203f is taken; if both radar water level meters 203f fail, the data of the immersion water level meter is used. In addition, a filtering algorithm is set in the local control unit to eliminate noise interference, a threshold value is set to identify water level meter failures, and fault-tolerant filtering parameters are used to ensure that the system can still operate normally when some equipment fails.

[0056] S3, water level monitoring, alarm and automatic control stage: according to the calculated water level value, the gate is automatically opened and closed; the local control unit analyzes the water level change trend according to the real-time water level data and historical data, and determines whether it is necessary to issue a flood control alarm according to the preset target water level dead zone (for example, 1542.15m is the upper limit control water level). When the water level reaches or exceeds this limit, the local control unit will automatically send a signal to the alarm system of the downstream flood discharge area, and send a warning message to the operator through the SCADA system;

[0057] When communication is normal, the operator can manually switch between single control and joint control mode. When the joint control mode is selected, the local control unit will automatically perform gate opening and closing operations according to the water level conditions. For example, when the upstream water level continues to be higher than the control water level (the default is 1542m) and a continuous net inflow is detected, the local control unit will open the sand flushing gate and the flood discharge gate in sequence. The height of the sand flushing gate for the first opening is 0.1m, and then the height of each opening shall not exceed 1m according to the water level changes. If the upstream water level drops to the lower limit control water level or below (for example, the default is 1541.85m), the local control unit will close the flood discharge gate 101b in sequence.

[0058] S4, emergency and optimization processing stage: During the gate control process, if the opening and closing relay nodes are stuck or external electromagnetic interference causes malfunction, the anti-malfunction protection program in the local control unit will monitor in real time and issue a stop command in time; if the change rate of the gate opening feedback value is monitored to exceed the preset range, the alarm will be automatically activated; in addition, the gate stop control logic has been optimized, and the logic of automatic stop has been added when the feedback opening value is greater than or less than the given value during the gate lifting or closing process to prevent the gate from repeated lifting and lowering.

[0059] S5, simulation mode test phase: In order to train operators or conduct system testing, the local control unit has a simulation mode; in this mode, the actual physical gate will not move, but the results of the gate operation and the impact of water level changes on the system can be simulated and displayed on the host computer screen of the centralized control center, which allows operators to become familiar with the operating system or test new parameters without affecting actual production.
