Description

Technical Field

[0001] This invention relates to the technical field of gate control, and more specifically, to a gate opening control system. Background Technology

[0002] Hydraulic sluice gates are hydraulic structures built on rivers, canals, lakes, or seas to control flow and regulate water levels. They primarily rely on sluice gates to control water flow and have the dual functions of blocking and diverting water. Closing the sluice gates can block floods, tides, and raise water levels to meet the needs of upstream water intake or navigation. Opening the sluice gates can release floodwaters, drain waterlogged areas, flush sediment, take in water, or regulate flow according to downstream water needs. Hydraulic sluice gates are generally built in plains areas, and their functions include flood control, water intake, drainage, navigation, and power generation, making them comprehensive water conservancy projects.

[0003] However, with the continuous occurrence of water quality problems, both the upstream and downstream basins on both sides of the water conservancy gate are subject to pollution to varying degrees. Moreover, there are significantly more pollution sources in the upstream basin than in the downstream basin, resulting in significantly more severe water pollution in the upstream basin. The normal flow of water in the downstream basin of the upstream basin will inevitably weaken the effect of water quality treatment. Therefore, the requirements for water conservancy gates are no longer limited to flood control, water intake, drainage, navigation, and power generation. There is an urgent need for a precise control system for the gates that can intelligently regulate the gate opening based on the degree of water pollution and water level, in order to cooperate with water quality treatment and improve the treatment effect. Summary of the Invention

[0004] The problem this invention aims to solve is: how to intelligently control the gate opening based on the degree of water pollution and water level, in order to cooperate with water quality treatment and improve the treatment effect.

[0005] To address the aforementioned problems, this invention provides a gate opening control system. Multiple gates are pre-installed at the confluence of the upstream and downstream sections of a river. Multiple first water level sensors are sequentially installed along the flow direction of the river in the upstream section, which is further divided into multiple upstream zones. Each upstream zone is equipped with a first water quality detector. Similarly, multiple second water level sensors are sequentially installed along the flow direction of the river in the downstream section, which is also divided into multiple downstream zones. Each downstream zone is equipped with a second water quality detector. The gate opening control system includes:

[0006] Multiple slave devices, each of which is connected to a corresponding gate, are used to collect the real-time opening degree of the corresponding gate;

[0007] A host computer is connected to each of the slave devices, each of the first water level sensors, each of the first water quality detectors, each of the second water level sensors, and each of the second water quality detectors. The host computer includes:

[0008] A first control module is used to control each of the first water level detectors, each of the first water quality detectors, each of the second water level sensors and each of the second water quality detectors to detect the corresponding first water level, first pollution level, second water level and second pollution level respectively.

[0009] An analysis module, connected to the first control module, is used to input each of the first water levels, each of the first pollution levels, each of the second water levels, each of the second pollution levels, and each of the real-time openings into a pre-trained opening analysis model to obtain an optimal opening for each of the gates.

[0010] A second control module, connected to the analysis module, is used to control each slave device to adjust the real-time opening degree of each gate to the corresponding optimal opening degree.

[0011] In this scheme, considering that the water quality and water level conditions may vary in different sections of the river, separate zones are established for the upstream and downstream sections. The pollution levels are measured by deploying the first and second water quality detectors in the respective upstream and downstream zones. Combining the first water level in each upstream section and the second water level in each downstream section, the opening analysis model is used to analyze the real-time opening to obtain the optimal opening of each gate. This ensures that when each gate is at its optimal opening, the water flow between the upstream and downstream sections does not affect normal water use. Simultaneously, it guarantees that the water quality treatment level in the downstream section and the pollution level from the upstream section are at their optimal treatment points, enabling coordinated water quality treatment and effectively improving the treatment outcome.

[0012] Preferably, the host further includes a drawing module, used to draw a river planar partition map based on the pre-acquired river channel structure data of the upstream and downstream of the river, the location information of each gate, each upstream partition and each downstream partition, and to draw a river depth map based on the river channel structure data of the upstream and downstream of the river, the location information of each first water level sensor and each second water level sensor for staff to view.

[0013] In this solution, by setting up the drawing module, the upstream and downstream of the river, each of the sluice gates, each of the upstream zones and each of the downstream zones are presented in the river planar zoning map for staff to view more intuitively. At the same time, the upstream and downstream of the river, each of the first water level sensors and each of the second water level sensors are presented in the river depth map for staff to view more intuitively. By combining the river planar zoning map and the river depth map, the entire view of the upstream and downstream of the river and each of the sluice gates can be viewed.

[0014] Preferably, each of the upstream and downstream zones is assigned a corresponding zone number, and each of the first and second water quality detectors is associated with the corresponding zone number. The host also includes a first visualization module connected to the drawing module, used to visualize each of the first and second pollution levels according to the corresponding zone number in the river planar zoning map, and to visualize each of the first and second water levels according to the location information of each of the first and second water level sensors in the river depth map.

[0015] In this solution, for the convenience of system identification, each upstream partition and each downstream partition is assigned a partition number. At the same time, the first pollution level detected by each first water quality detector and the second pollution level detected by each second water quality detector are displayed in the corresponding upstream or downstream partition according to the partition number, so that staff can intuitively grasp the pollution status of each partition.

[0016] Furthermore, considering that the location setting logic of each first water level sensor and each second water level sensor may differ from the river's zoning logic, i.e., zoning cannot be used to represent the specific location of each first water level sensor and each second water level sensor, the first water level detected by each first water level sensor and the second water level detected by each second water level sensor are displayed in the river depth map according to the location information of the water level sensors, so that staff can intuitively grasp the water level situation at various locations in the upstream and downstream of the river.

[0017] Preferably, each of the gates corresponds to a digital code, and each slave device is associated with the corresponding digital code. The master device also includes a second visualization module connected to the drawing module, used to visualize the real-time opening of each gate according to the corresponding digital code in the river planar partition map.

[0018] In this scheme, for the convenience of system identification, each gate is assigned a digital code. At the same time, the real-time opening degree of each gate collected by each slave device is displayed in the river planar partition map according to the digital code, so that the staff can intuitively grasp the opening degree of each gate.

[0019] Preferably, the host further includes an emergency control module connected to the second control module, used to output an emergency control signal to the second control module according to the emergency command when receiving an externally input emergency command, so that the second control module controls each of the gates to close according to the emergency control signal.

[0020] In this solution, by setting up the emergency control module, it can be ensured that all the gates can be closed directly with one click in an emergency, avoiding the harm caused by untimely closure.

[0021] Preferably, the host further includes a model training module connected to the analysis module, used to collect multiple sets of historical control data including multiple historical upstream water levels, multiple historical downstream water levels, multiple historical upstream pollution levels, multiple historical downstream pollution levels, a historical total opening value before adjustment, and a historical total opening value after adjustment. For each set of historical control data, a corresponding variable weight is configured for each of the historical upstream water levels, historical downstream water levels, historical upstream pollution levels, historical downstream pollution levels, and the historical total opening value before adjustment. The historical total pollution value after adjustment is obtained through weighted calculation. The model is trained by taking each of the historical upstream water levels, historical downstream water levels, historical upstream pollution levels, historical downstream pollution levels, and the historical total opening value before adjustment as input and the corresponding historical total opening value after adjustment as output.

[0022] In this scheme, multiple sets of historical control data are used as training data for the opening degree analysis model. The historical upstream water level, historical downstream water level, historical upstream pollution level, historical downstream pollution level, historical opening degree before adjustment, and historical opening degree after adjustment are used as training bases. The accuracy of machine learning is improved through multi-dimensional, multi-level, and multi-category data calculation.

[0023] Preferably, the total opening value before the historical adjustment is the sum of the opening values ​​before the historical adjustment for each of the gates, and the total opening value after the historical adjustment is the sum of the opening values ​​after the historical adjustment for each of the gates.

[0024] Preferably, each of the slave devices is connected to the gate through a gate opening meter, then the second control module controls each of the gate opening meters to adjust the real-time opening of each gate to the corresponding optimal opening. Attached Figure Description

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] In a preferred embodiment of the present invention, based on the aforementioned problems existing in the prior art, a gate opening control system is provided. Multiple gates 1 are pre-installed at the confluence of the upstream and downstream sections of a river. Multiple first water level sensors 2 are sequentially installed along the flow direction of the river in the upstream section, and the upstream section is divided into multiple upstream zones, each equipped with a first water quality detector 3. Multiple second water level sensors 4 are sequentially installed along the flow direction of the river in the downstream section, and the downstream section is divided into multiple downstream zones, each equipped with a second water quality detector 5. Figure 1 As shown, the gate opening control system includes:

[0029] Multiple slave devices 6, each slave device 6 is connected to a corresponding gate 1, and is used to collect the real-time opening degree of the corresponding gate 1;

[0030] A host 7 is connected to each slave device 6, each first water level sensor 2, each first water quality detector 3, each second water level sensor 4, and each second water quality detector 5. The host 7 includes:

[0031] A first control module 71 is used to control each first water level detector 2, each first water quality detector 3, each second water level sensor 4 and each second water quality detector 5 to detect the corresponding first water level, first pollution level, second water level and second pollution level respectively.

[0032] An analysis module 72, connected to the first control module 71, is used to input each first water level, each first pollution degree, each second water level, each second pollution degree, and each real-time opening degree into a pre-trained opening degree analysis model to obtain an optimal opening degree corresponding to each gate 1.

[0033] A second control module 73 is connected to the analysis module 72 and is used to control each slave device 6 to adjust the real-time opening degree of each gate 1 to the corresponding optimal opening degree.

[0034] Specifically, in this embodiment, considering that the water quality and water level conditions of different blocks in the river may vary, the upstream and downstream sections of the river are divided into zones. The pollution levels are measured by deploying a first water quality detector 3 and a second water quality detector 5 in the respective upstream and downstream zones. The optimal opening of each gate 1 is obtained by combining the first water level of each block in the upstream and the second water level of each block in the downstream using an opening analysis model. This ensures that when each gate 1 is at its optimal opening, the water flow between the upstream and downstream sections does not affect normal water use. At the same time, it ensures that the water quality treatment level in the downstream section and the water pollution level from the upstream section are at the optimal treatment level, enabling coordinated water quality treatment and effectively improving the treatment effect.

[0035] Preferably, multiple first water level sensors 2 are sequentially installed in the upstream section of the river along the direction of water flow, and multiple second water level sensors 4 are sequentially installed in the downstream section of the river along the direction of water flow to achieve river water level detection in each block, ensuring full coverage of water level detection.

[0036] Preferably, the river's upstream section is divided into multiple upstream zones, with a first water quality detector 3 installed in each upstream zone, and the river's downstream section is divided into multiple downstream zones, with a second water quality detector 5 installed in each downstream zone, to achieve river pollution detection in each zone and ensure full coverage of pollution detection.

[0038] Specifically, in this embodiment, by setting up a drawing module 74, the upstream and downstream of the river, each gate 1, each upstream zone and each downstream zone are presented in the river planar zoning map for staff to view more intuitively. At the same time, the upstream and downstream of the river, each first water level sensor 2 and each second water level sensor 4 are presented in the river depth map for staff to view more intuitively. By combining the river planar zoning map and the river depth map, the overall view of the upstream and downstream of the river and each gate 1 can be viewed.

[0039] Preferably, the river planar zoning map can present the location of the upstream and downstream sections of the river, each gate 1, each upstream section and each downstream section from a top-down perspective, while the river depth map can present the location of the upstream and downstream sections of the river, each first water level sensor 2 and each second water level sensor 4 from a cross-sectional perspective.

[0040] Preferably, the river planar zoning map and the river depth map can be obtained by scaling the river channel structure data of the upper and lower reaches of the river proportionally by several times.

[0041] Preferably, considering that the location setting logic of each first water level sensor 2 and each second water level sensor 4 may differ from the river zoning logic, i.e., zoning cannot be used to represent the specific location of each first water level sensor 2 and each second water level sensor 4, the first water level detected by each first water level sensor 2 and the second water level detected by each second water level sensor 4 are displayed in the river depth map according to the location information of the water level sensors, so that the staff can intuitively grasp the water level situation at various locations in the upstream and downstream of the river.

[0042] In a preferred embodiment of the present invention, each upstream zone and each downstream zone is provided with a corresponding zone number, each first water quality detector 3 and each second water quality detector 5 are respectively associated with the corresponding zone number, and the host 7 also includes a first visualization module 75 connected to a drawing module 74, used to visualize each first pollution level and each second pollution level according to the corresponding zone number in the river planar zoning map, and to visualize each first water level and each second water level according to the position information of each first water level sensor 2 and each second water level sensor 4 in the river depth map.

[0043] Specifically, in this embodiment, for the convenience of system identification, a partition number is set for each upstream partition and each downstream partition. At the same time, the first pollution degree detected by each first water quality detector 3 and the second pollution degree detected by each second water quality detector 5 are displayed in the corresponding upstream or downstream partition according to the partition number, so that the staff can intuitively grasp the pollution status of each partition.

[0044] Preferably, in actual operation, different shades of color can be used to represent different zones based on their level of contamination, making the zones with higher levels of contamination more obvious and intuitive.

[0045] In a preferred embodiment of the present invention, each gate 1 corresponds to a digital code, each slave device 6 is associated with the corresponding digital code, and the master device 7 further includes a second visualization module 76 connected to the drawing module 74, which is used to visualize the real-time opening of each gate 1 in the river planar partition map according to the corresponding digital code.

[0046] Specifically, in this embodiment, for the convenience of system identification, each gate 1 is assigned a digital code. At the same time, the real-time opening degree of each gate 1 collected by each slave device 6 is displayed in the river planar partition map according to the digital code, so that the staff can intuitively grasp the opening degree of each gate 1.

[0047] In a preferred embodiment of the present invention, the host 7 further includes an emergency control module 77 connected to the second control module 73, which is used to output an emergency control signal to the second control module 73 according to the emergency command when receiving an externally input emergency command, so that the second control module 73 controls each gate 1 to close according to the emergency control signal.

[0048] Specifically, in this embodiment, by setting up an emergency control module 77, it can be ensured that all gates 1 can be closed directly with one click in an emergency, avoiding harm caused by untimely closure.

[0049] In a preferred embodiment of the present invention, the host 7 further includes a model training module 78 connected to the analysis module 72, used to collect multiple sets of historical control data including multiple historical upstream water levels, multiple historical downstream water levels, multiple historical upstream pollution levels, multiple historical downstream pollution levels, a total opening value before historical adjustment, and a total opening value after historical adjustment. For each set of historical control data, a corresponding variable weight is configured for each historical upstream water level, each historical downstream water level, each historical upstream pollution level, each historical downstream pollution level, and the total opening value before historical adjustment. The total pollution value after historical adjustment is obtained through weighted calculation. The opening analysis model is trained by taking each historical upstream water level, each historical downstream water level, each historical upstream pollution level, each historical downstream pollution level, and the total opening value before historical adjustment as input and the corresponding total opening value after historical adjustment as output.

[0050] Specifically, in this embodiment, multiple sets of historical control data are used as training data for the opening degree analysis model. The historical upstream water level, historical downstream water level, historical upstream pollution level, historical downstream pollution level, historical opening degree before adjustment, and historical opening degree after adjustment are used as training bases. The accuracy of machine learning is improved through multi-dimensional, multi-level, and multi-category data calculation.

[0051] Preferably, during the continuous simulation and calculation process, the specific parameters of each variable weight are continuously adjusted to continuously improve the accuracy of the optimal opening obtained by the opening analysis model.

[0052] In a preferred embodiment of the present invention, the total opening value before historical adjustment is the sum of the opening values ​​before historical adjustment for each gate 1, and the total opening value after historical adjustment is the sum of the opening values ​​after historical adjustment for each gate 1.

[0053] Specifically, in this embodiment, the opening degree analysis model obtains the sum of the optimal opening degrees. The staff can assign the corresponding optimal opening degree to each gate 1 according to the real-time opening degree of each gate 1 under the actual situation, so that the adjustment range of the opening degree of each gate 1 is minimized.

[0054] In a preferred embodiment of the present invention, each slave device 6 is connected to the gate 1 through a gate opening device 8, and the second control module 73 controls each gate opening device 8 to adjust the real-time opening of each gate 1 to the corresponding optimal opening.
