Description

Technical Field

[0001] This invention relates to the field of urban drainage system control technology, specifically to an integrated operation control method, computer equipment, and storage medium for drainage area plants, stations, and networks. Background Technology

[0002] With the acceleration of urbanization, the operation and management of drainage systems face multiple pressures, including flood prevention, pollution control, and operational efficiency. Currently, urban drainage systems typically include sewage systems, stormwater systems, and combined sewer systems, involving various facilities such as sewage treatment plants, interceptor pumping stations, stormwater pumping stations, storage tanks, connecting pipes, and terminal distribution wells. However, in actual operation and control, the following technical problems commonly exist: (1) Fragmented system and lack of coordination: Wastewater treatment plants, pumping stations (intercepting pumps, flood control pumps), storage tanks and pipeline trunk lines are often controlled independently by different systems or platforms. The lack of information linkage between plants, stations and networks leads to a mismatch between upstream water inflow and downstream treatment capacity, which can easily cause load shocks to wastewater treatment plants or high water levels in pipelines.

[0003] (2) Fixed control logic with poor adaptability: Most pumping stations rely on a single forebay liquid level threshold for start-up and shutdown control (such as high start-up and low stop-up). This logic cannot be dynamically adjusted according to different operating conditions such as dry weather and rainy weather. Especially during moderate to heavy rain, it is easy for rainwater to enter the sewage system in large quantities, crowding out the sewage pipe network capacity, increasing the treatment pressure of sewage treatment plants and the risk of water overflow pollution.

[0004] (3) Low utilization rate of water storage facilities: For pumping stations equipped with water storage tanks, there is usually a lack of refined "storage-discharge" linkage strategy. Water storage tanks are often passively stored, or blindly emptied after rainfall without considering the remaining capacity of the pipeline network, which fails to maximize their peak shaving and valley filling effects.

[0005] (4) Reliance on manual experience and delayed response: When faced with sudden rainfall, dispatchers need to manually start and stop pump groups or open and close connecting pipes based on experience. This is not only labor-intensive, but also makes it difficult to make decisions in response to rapidly changing water conditions, which can easily lead to local water accumulation or overflow.

[0006] Therefore, how to achieve integrated and coordinated control of drainage plants, stations, and networks in a drainage area based on real-time monitoring data, combined with geographical features and pipeline topology, is a technical problem that urgently needs to be solved in this field. To address the above problem, this invention provides an integrated operation control method for drainage plants, stations, and networks in a drainage area, enabling standardized, refined, and coordinated operation control of the drainage system under different operating modes. Summary of the Invention

[0007] Based on this, a method, device, computer equipment, and storage medium for integrated operation and control of drainage area plants, stations, and networks are provided to solve the technical problems existing in the operation and control of urban drainage systems, such as the lack of coordination in the independent management and control of facilities in plants, stations, and networks, the inability of pump station control logic to adapt to changes in rainfall conditions, low utilization rate of storage tank facilities, and lag in manual dispatch response, which in turn lead to high water level operation of the pipe network, load impact on terminal treatment plants, high risk of waterlogging and overflow pollution, and insufficient system operation efficiency.

[0008] This application provides a method for integrated operation and control of drainage area power plants and networks, including the following steps: Based on geographical features, the topological connection relationship of trunk and branch pipeline networks and the location of key node pumping stations, the drainage area, which includes sewage / combined sewer interceptor pumps, stormwater interceptor pumps, stormwater flood control pumps, combined / stormwater pumping station storage tanks, inter-area connecting pipes and end-of-area water distribution wells, is divided into several sub-areas. Based on rainfall monitoring data in each sub-area, the rainfall intensity is calculated and the current operating mode of the sub-area is determined. The operating modes include drought mode, light rain mode, moderate rain mode, heavy rain mode, and post-rain mode. The target traffic limit for the sub-area is determined based on its current operating mode. For each sub-area, based on the current operating mode, the start / stop liquid level threshold of the intercepting pump / interception pump, and the target flow limit, a start / stop control strategy for the intercepting pump and the interception pump, as well as a linkage control strategy for the flood control pump and the regulating tank are generated. Based on the inflow and load rate of the end-of-pipe treatment plant, excess water exceeding the load of the end-of-pipe treatment plant is diverted to other sub-area end-of-pipe treatment plants or temporarily stored in the storage tank. The diversion ratio of the end-of-pipe distribution wells in the area is adjusted, and a coordinated scheduling strategy for the end-of-pipe plant network is generated to coordinate and control the end-of-pipe distribution wells, end-of-pipe storage tanks, and connecting pipes to other sub-areas in the area. The start-stop control strategy, the linkage control strategy, and the terminal plant network collaborative scheduling strategy are executed cyclically at a preset period to achieve rolling optimization control of the integrated plant network in the drainage area.

[0009] Furthermore, the drainage area, which includes sewage / combined sewer interceptor pumps, stormwater interceptor pumps, stormwater flood control pumps, combined sewer / stormwater pump storage tanks, inter-area connecting pipes, and end-of-area distribution wells, is divided into several sub-areas, including: The criteria for dividing sub-regions include geographical boundary features, the topological connection relationship between trunk and branch pipeline networks, the location of key node pump stations, and the distribution of trunk pipelines from each sub-region to the terminal treatment plant. Based on the aforementioned sub-zone division criteria, the drainage zone, which includes sewage / combined sewer interceptor pumps, stormwater interceptor pumps, stormwater flood control pumps, combined sewer / stormwater pump storage tanks, inter-zone connecting pipes, and end-of-zone distribution wells, is divided into several independently controllable sub-zones.

[0010] Furthermore, the step of calculating rainfall intensity and determining the current operating mode of each sub-area based on rainfall monitoring data includes: Real-time rainfall data from each monitoring point is obtained, and the rainfall intensity at each monitoring point in the sub-area within a preset time interval is calculated using the formula I=∆R / ∆t; where, Rainfall intensity (mm / h) The cumulative rainfall over the period is in mm. The time interval is (h). When the proportion of rainfall with an intensity greater than 0.1 mm exceeds a preset threshold, it is identified as a rainfall event and the rain mode is entered; otherwise, it is determined that there is no valid rainfall signal. When the cumulative rainfall in 24 hours is less than or equal to 10 mm, it is determined to be a light rain pattern; when the cumulative rainfall in 24 hours is greater than 10 mm, it is determined to be a moderate rain pattern; when the cumulative rainfall in 24 hours is greater than 25 mm, it is determined to be a heavy rain pattern. When there is no effective rainfall signal, check whether there are historical rainfall event records within the preset time window. If there are historical rainfall records, it is determined to be a post-rain mode; if there are no historical rainfall records, it is determined to be a dry weather mode.

[0011] Furthermore, determining the target traffic limit for the sub-region based on its current operating mode includes: In the dry weather mode, the target flow limit for the sub-area is the product of the average dry weather flow over the past three days and the dry weather mode coefficient. In the post-rain mode, the target flow limit for the sub-area is the product of the average flow of the past three dry days and the post-rain mode coefficient. In the light rain mode, the target flow limit for the sub-area is the product of the average flow of the past three dry days and the rainy day mode coefficient. In both moderate and heavy rain modes, the target flow limit for the sub-area is a preset fixed threshold.

[0012] Furthermore, the start-stop control strategy for generating the intercepting pump and the intercepting pump includes: In dry weather mode and post-rain mode, the liquid level difference is calculated and arranged in descending order based on the start-up and stop liquid level of the interceptor pump / interception pump and the real-time liquid level of each pump station. Pump stations with real-time liquid levels higher than the start-up water level of the interceptor pump / interception pump are included in the list to be opened, and pump stations with real-time liquid levels lower than the stop-up water level of the interceptor pump / interception pump are included in the shutdown strategy. The pump stations in the list to be activated are judged in order of arrangement. The real-time flow of the current sub-area and the flow increment of the intercepting pump with the minimum available nameplate flow are read. When the sum of the real-time flow and the flow increment is less than the target flow limit, the pump station is included in the activation strategy. Once the pump stations in the list to be activated have been identified, each pump station is controlled to activate at most one new pump in each activation strategy. In light rain, moderate rain, and heavy rain modes, the intercepting pumps of each pumping station generate and execute start-up and shutdown strategies according to the control methods used in dry weather and post-rain modes, and the intercepting pumps of each pumping station form shutdown strategies to shut down one by one.

[0013] Furthermore, the linkage control strategy for generating flood control pumps and regulating reservoirs includes: In dry weather mode and post-rain mode, flood control pumps are shut down one by one, and storage tanks are shut down or emptied. In light rain, moderate rain, and heavy rain modes, for flood control pumps without storage tanks, the start and stop are controlled based on the start / stop liquid level of the flood control pump forebay and the real-time liquid level of each pumping station. The flood control pump is activated when the current liquid level of the storage tank is higher than the flood control activation level, and the flood control pump is shut down when the current liquid level of the storage tank is lower than the flood control shutdown level. For flood control pumps equipped with storage tanks, the storage tanks are used to temporarily store rainwater, and the flood control pumps are activated after the utilization rate of the storage tanks reaches the saturation threshold.

[0014] Furthermore, for the flood control pump equipped with a storage tank, the method of temporarily storing rainwater in the storage tank and activating the flood control pump after the storage tank reaches a saturation threshold includes: When using the stormwater storage tank to temporarily store rainwater, calculate the utilization rate of the stormwater storage tank and monitor the current liquid level of the stormwater storage tank in real time. If the current liquid level of the storage tank is higher than the flood control activation water level and the utilization rate of the storage tank has not reached the saturation threshold, the storage tank shall remain in the water intake state and the flood control pump shall remain closed. If the current liquid level of the storage tank is higher than the flood control activation level and the utilization rate of the storage tank reaches the saturation threshold, the water intake of the storage tank shall be stopped and the flood control pump shall be activated for drainage.

[0015] Furthermore, the coordinated scheduling strategy for the terminal water distribution wells, terminal storage tanks, and connecting pipes linking other sub-regions within the coordinated control area includes: After the rainfall event ends, the list of storage tanks to be emptied in the sub-area is obtained and formed. The list of storage tanks to be emptied is read, and the water discharge operation of the storage tanks is performed under the premise that the real-time flow rate in the sub-area does not exceed the target flow rate limit, until the water level of the storage tank drops to the minimum level, and then the water discharge is stopped.

[0016] This application also provides a computer device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, characterized in that the processor executes the computer program to implement the steps of any of the methods described above.

[0017] This application also provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of any of the methods described above.

[0018] Compared with existing technologies, the present invention has the following beneficial effects: by dividing the drainage area into sub-areas, determining multiple operating modes based on rainfall monitoring data, determining the target flow limit of the sub-area according to different operating conditions, generating control strategies for the start-up and shutdown of intercepting pumps and intercepting diversion pumps and the linkage between flood control pumps and regulating reservoirs, and carrying out coordinated water volume scheduling of terminal plants, stations and networks and performing optimized control in a preset cycle, the information barriers between plants, stations and networks can be broken down, and coordinated regulation of the entire system facilities can be achieved. This enables the drainage system to automatically adapt the control logic according to rainfall conditions, effectively balance the pipeline network's transmission capacity and the terminal treatment plant's processing load, reduce the risk of urban flooding and combined sewer overflow pollution, and improve the system's operational resilience, intelligence level and overall management efficiency.

[0019] Figure 1 This is a flowchart of the integrated operation and control method for drainage area plants and networks provided in Embodiment 1 of the present invention; Figure 2 This is a flowchart of the integrated operation and control method for drainage area plants and networks provided in Embodiment 2 of the present invention; Figure 3 This is an internal structural diagram of the computer device in an embodiment of the present invention. Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1 like Figure 1 As shown, Embodiment 1 of the present invention provides an integrated operation and control method for drainage area plants, stations, and networks, which can be implemented through the following steps S1-S7, as detailed below: S1. Sub-area division: Based on geographical features, the topological connection relationship of trunk and branch pipeline networks and the location of key node pumping stations, the drainage area, which includes sewage / combined sewer interceptor pumps, stormwater interceptor pumps, stormwater flood control pumps, combined / stormwater pumping station storage tanks, inter-area connecting pipes and end-of-area water distribution wells, etc., is divided into several drainage sub-areas.

[0022] S2. Sub-area operation mode determination: Based on rainfall monitoring data in each sub-area, the rainfall intensity is calculated and the current operation mode is determined. The operation modes include dry weather mode, light rain mode, moderate rain mode, heavy rain mode, and post-rain mode.

[0023] S3. Calculation of target flow limit for sub-area: The target flow limit for each sub-area is determined according to the operating mode. In dry weather mode and post-rain mode, the target flow limit is the product of the average flow of the past three dry days and the dry weather mode coefficient. In light rain mode, the target flow limit is the product of the average flow of the past three dry days and the rainy weather mode coefficient. In moderate rain mode and heavy rain mode, the target flow limit is a preset fixed threshold. The above coefficients and fixed thresholds are all pre-set static parameters.

[0024] S4. Generation of sewage transport strategy for drainage sub-area: The start and stop of interceptor pumps / interception pumps are based on the operating mode, liquid level threshold (pump start and stop liquid level) and flow limit to form a differentiated control strategy. In dry weather and post-rain weather modes, the liquid level difference is calculated and sorted in reverse order based on the start / stop liquid levels and real-time liquid levels of the interceptor pumps / interception pumps at each pump station. Only pump stations with real-time liquid levels higher than the start-up water level of the interceptor pumps / interception pumps are included in the list to be activated. Starting from the first pump station in the list, the real-time flow rate of the current sub-area and the flow increment of a single interceptor pump are read. The flow increment is preferentially selected based on the interceptor pump with the smallest available nameplate flow rate. When the sum of the real-time flow rate and the flow increment is less than the target flow limit, the pump is officially included in the activation strategy. The list to be activated is checked from top to bottom to see if each pump can be included in the activation strategy until the sum of the real-time flow rate and the flow increment is greater than the target flow limit or the list ends. Each pump station can only activate one new pump each time a strategy is generated. Pump stations with real-time liquid levels lower than the stop-use water level of the interceptor pumps / interception pumps are included in the shutdown strategy. In light rain, moderate rain, and heavy rain modes, the interceptor pumps still form activation and shutdown strategies according to the above logic; interceptor pumps need to be shut down one by one, and only shutdown strategies are formed.

[0025] S5. Generation of Rainwater Transport Strategy for Drainage Sub-areas: Based on the aforementioned operating mode, liquid level threshold (pump start / stop liquid level), and flow limit, differentiated linkage control strategies are generated for the start / stop of flood control pumps and the inflow / outflow of storage tanks. In dry weather and post-rain weather modes, flood control pumps must be shut down one by one, resulting in only a shutdown strategy; storage tanks only generate shutdown or venting strategies. In light rain, moderate rain, and heavy rain modes; for flood control pumps without storage tanks, based on the start / stop liquid level and real-time liquid level of the flood control pump forebay at each pumping station, the flood control pump is activated when the current liquid level is higher than the flood control activation level, and shut down when it is lower than the flood control shutdown level, with a maximum of one new flood control pump activated per pumping station per strategy generation; for flood control pumps with storage tanks, the storage tank is used to temporarily store rainwater, and the flood control pump is activated only when the utilization rate of the storage tank reaches the saturation threshold, with the activation strategy as described above.

[0026] S6. Collaborative Scheduling of Terminal Plants and Stations: Based on the flow rate and load rate of the main pipeline entering the terminal treatment plant, when the load of the terminal treatment plant exceeds the preset threshold, the connecting pipes to other drainage areas are opened. At the same time, the strategy of the terminal sewage treatment plant's storage tank is adjusted to divert excess water to other terminal treatment plants in drainage areas or temporarily store it in the storage tank. Simultaneously, the diversion ratio of the distribution well is adjusted to control the flow rate of each production line entering the treatment plant, forming a collaborative scheduling strategy for the terminal distribution wells, terminal storage tanks, and connecting pipes to other drainage areas in the drainage area.

[0027] S7. Cyclic Optimization Control: Steps S2 to S6 are repeated over a preset time period to achieve rolling optimization control of the integrated drainage area plant and network.

[0028] Among them, by dividing the drainage area into sub-areas, determining multiple operating modes based on rainfall monitoring data, determining the target flow limit of the sub-area according to different operating conditions, generating control strategies for the start and stop of intercepting sewage pumps and intercepting diversion pumps and the linkage between flood control pumps and regulating reservoirs, and carrying out coordinated water volume scheduling of terminal plants, stations and networks and performing optimized control in a preset cycle, it is possible to break down the information barriers between plants, stations and networks, realize the coordinated regulation of the entire system facilities, enable the drainage system to automatically adapt the control logic according to rainfall conditions, effectively balance the pipeline network's transmission capacity and the terminal treatment plant's processing load, reduce the risk of urban flooding and combined sewer overflow pollution, and improve the system's operational resilience, intelligence level and overall management efficiency.

[0029] like Figure 1 As shown in the figure, this embodiment details the implementation method of sub-segment division and operation mode determination.

[0030] In step S1, the system divides the sub-areas into sections. The division is based on: geographical boundary features, such as natural or artificial boundaries like rivers and roads; the topological connection relationship between trunk and branch pipelines, analyzing the pipeline connection methods and flow directions between pumping stations; the geographical location of key node pumping stations, identifying pumping stations that play a key role in the drainage of the area; and the distribution of trunk pipelines from each sub-area to the end-of-pipe treatment plant, determining the final destination of water flow in each sub-area.

[0031] The facilities within the sub-area include: interceptor pumps at the sewage / combined sewer pumping station for transporting sewage to the treatment plant; interceptor pumps at the stormwater pumping station for intercepting initial rainwater runoff during rainy weather; flood control pumps at the stormwater pumping station for discharging rainwater to prevent flooding; storage tanks at the combined sewer / stormwater pumping station for temporarily storing stormwater and sewage; inter-area connecting pipes for connecting different sub-areas to achieve water volume allocation; and end-of-area distribution wells for allocating water entering the treatment plant.

[0032] In step S2, the system determines the operating mode of each sub-region. The determination process is as follows: First, the system selects pump stations equipped with rain gauges within each sub-area and obtains real-time rainfall data from each monitoring point. The rainfall intensity at each monitoring point within a preset time interval is calculated using the following formula: In the formula, Rainfall intensity (mm / h) The cumulative rainfall over the period is in mm. The time interval is (h).

[0033] Then, the number of valid rainfall signals is counted. When the proportion of rainfall with a cumulative rainfall difference (rainfall intensity) greater than 0.1 mm exceeds a preset proportion threshold (e.g., 30%), it is identified as a rainfall event, and the rainy weather mode is entered.

[0034] After entering the rain mode, the rain type is further distinguished based on the cumulative rainfall intensity: when the cumulative rainfall in 24 hours is less than or equal to 10 mm, it is determined to be light rain mode; when the cumulative rainfall in 24 hours is greater than 10 mm, it is determined to be moderate rain mode; when the cumulative rainfall in 24 hours is greater than 25 mm, it is determined to be heavy rain mode.

[0035] When the number of valid rainfall signals does not exceed the threshold, check whether there are historical rainfall event records within a preset time window (e.g., 48 hours). If they exist, it is determined to be post-rain mode; if not, it is determined to be dry weather mode. Post-rain mode helps maintain high drainage capacity for a period of time after rainfall ends, preventing overflow caused by residual rainwater in the pipe network.

[0036] This embodiment details the implementation of the target flow calculation and the throttling pump start / stop strategy. In step S3, the system calculates the target flow limit for each sub-area based on the determined operating mode. The calculation formula is as follows: In dry weather mode: After-Rain Mode: In light rain mode: In moderate rain mode: In heavy rain mode: In the formula, The average flow rate (m³) during dry weather at this time over the past three days. 3 / h), This represents the drought pattern coefficient. This represents the post-rain pattern coefficient. For light rain pattern coefficients, and To preset fixed thresholds (m) for target flow rates under moderate and heavy rain modes. 3 / h). The above coefficients and fixed thresholds are all pre-set static parameters that can be adjusted according to actual operating conditions.

[0037] In step S4, the system generates a sewage transport strategy for the drainage area. The start and stop of the interceptor pumps / interception pumps are based on differentiated control strategies according to the operating mode, liquid level threshold, and flow limit.

[0038] The specific functions of interceptor pumps / interception pumps are described below: Interception pumps: installed in sewage pumping stations and combined sewer pumping stations, used to transport sewage and rainwater; intercepting sewer pumps: installed in separate sewer rainwater pumping stations, used to transport small amounts of sewage from rainwater pipes; The start-stop control procedure for the interceptor pump in dry weather mode and post-rain mode is as follows: The first step is to create a list of pump stations to be activated. The system reads the cutoff water level of each pump station in the current sub-area. and real-time liquid level Calculate the liquid level difference The pump stations are sorted in descending order of their liquid level differences (higher priority for larger differences). The order is further adjusted by considering factors such as the priority of pump stations prone to water accumulation and their overall importance, ultimately forming a list of pump stations to be activated. Only pump stations with real-time liquid levels higher than the cutoff activation level (i.e.,...) are activated. > Pump stations that are scheduled to be activated are added to the list. The list is updated hourly.

[0039] The second step is to initiate the identification process. Identification begins with the first pump station in the list of pump stations to be activated. The system reads the real-time traffic flow of the current sub-region. and the flow increment of activating a single throttling pump Traffic increment The throttling pump with the lowest currently available nameplate flow rate is preferentially selected as the basis for calculation. The selection criterion is: When the above conditions are met, the pump is officially included in the activation strategy. The pump in the activation list is checked from top to bottom to see if it qualifies for activation, until the sum of the real-time flow rate and the flow increment exceeds the target flow limit. (or end of list). Each pump station can only start a maximum of one new pump per policy generation.

[0040] The third step is to close the detection mechanism. When the liquid level in the pump station's forebay is lower than the cutoff water level (… < When this happens, the pumping station will be included in the shutdown strategy, and each intercepting pump will be shut down one by one.

[0041] During light, moderate, and heavy rain conditions, the intercepting pumps will still follow the above logic to form an on / off strategy; the intercepting pumps need to be shut down one by one, forming only a shutdown strategy, to avoid overloading the sewage network during rainy days.

[0042] This embodiment details the implementation of the linkage control between flood control pumps and storage tanks under rainy weather conditions. In step S5, the system generates a rainwater transport strategy for the drainage area. The start / stop of the flood control pumps and the inflow / outflow of the storage tanks are based on differentiated linkage control strategies according to the operating mode, liquid level threshold, and flow limit.

[0043] The specific functions of flood control pumps are described below: Flood control pumps: installed in combined pumping stations and stormwater pumping stations, used to discharge rainwater to nearby surface water bodies (not sewage treatment plants).

[0044] In dry weather and post-rain weather modes, flood control pumps need to be shut down one by one, forming only a shutdown strategy; storage tanks only form a shutdown or venting strategy.

[0045] In light rain, moderate rain, and heavy rain modes, the system implements different control strategies depending on whether the pumping station is equipped with a regulating reservoir.

[0046] For flood control pumps without regulating reservoirs, the control logic is as follows: Based on the start-up and stop liquid levels and real-time liquid levels in the flood control pump forebay of each pumping station, the current liquid level is higher than the flood control activation water level ( > Flood control pumps should be activated when the water level is below the flood control shutdown level. < The flood control pumps will be shut down when the strategy is generated. Each pumping station can only have one new flood control pump activated each time a strategy is generated.

[0047] For flood control pumps equipped with stormwater storage tanks, the system prioritizes the use of these tanks to temporarily store rainwater. The utilization rate of the stormwater storage tanks needs to be calculated first. : In the formula, The utilization rate (%) of the storage tank. The current liquid level (m) of the storage tank. This represents the lowest liquid level (m) in the storage tank. This represents the highest liquid level (m) in the storage tank. The lowest and highest liquid levels can be the lowest / highest values ​​from historical liquid level data, or the upper and lower elevations of the storage tank itself.

[0048] The control logic is as follows: The current liquid level is higher than the flood control activation level ( > And the utilization rate of the storage tank has not reached the saturation threshold. < When the utilization rate of the storage tank reaches a saturation threshold (e.g., 95%), the storage tank remains in an inflow state, and the flood control pump remains shut off. ≥ When the water level in the regulating reservoir drops below the flood control shutdown level, the water intake should be stopped and the flood control pumps should be activated for drainage. < When this occurs, shut off the flood control pumps.

[0049] The system also determines the current state of the storage tank based on the liquid level change within a preset time interval. Let the current liquid level be... The liquid level in the previous time interval was The change in liquid level When the liquid level rise exceeds the change threshold ( > When the water level drops by more than a certain threshold, it is considered to be in a water inflow state; when the drop in water level exceeds the threshold value, it is considered to be in a water inflow state. < If the water level is low, it is considered to be in a state of water release; otherwise, it is considered to be in a stable state.

[0050] This embodiment details the implementation of the reservoir emptying control strategy. After a rainfall event ends, the system determines the emptying mode. First, it automatically reads the list of reservoirs to be emptied within the current sub-area and inputs the real-time flow rate. and target traffic limit .

[0051] The core criteria for air venting control are: ; Provided that the real-time flow rate does not exceed the target flow rate limit, the water discharge operation of the storage tank is executed. Water continues to be discharged from the storage tank until the water level drops to the minimum level. = At this point, water flow will stop.

[0052] Recommended operating rules for water storage tanks are determined based on a comprehensive consideration of utilization rate and current status: (1) When the current state of the storage tank is in the inflow state (in) and the utilization rate exceeds the minimum storage capacity ratio threshold ( > If this occurs, it is recommended to stop the water intake and drain the system. (2) When the current state of the storage tank is inflow (in) and the utilization rate does not exceed the minimum storage capacity ratio threshold ( ≤ When this occurs, it is recommended to keep the area dry. (3) When the current state of the storage tank is stable (close) and the utilization rate exceeds the minimum storage capacity ratio threshold ( > When this happens, it is recommended to short sell; (4) When the current state of the storage tank is stable (close) and the utilization rate does not exceed the minimum storage capacity ratio threshold ( ≤ When this is the case, it is recommended to keep the area dry.

[0053] in, This is the minimum storage capacity ratio threshold, a pre-set static parameter.

[0054] This embodiment details the implementation of the coordinated scheduling of terminal treatment plant networks. In step S6, the system executes a coordinated scheduling strategy for terminal distribution wells, connecting pipes, and storage tanks based on the flow rate and load rate of the main inlet pipes of the terminal treatment plants.

[0055] The system first monitors the inlet flow of each terminal treatment plant and calculates the total flow into the terminal treatment plants from each sub-region. Simultaneously calculate the load factor of the end-of-pipe treatment plant. : ; In the formula, The load factor (%) of the end-of-pipe treatment plant. Total inflow rate (m³) 3 / h), Design processing capacity (m) for end-of-pipe treatment plants 3 / h).

[0056] When the load of the end-of-pipe treatment plant is within the normal range ( ≤ When this occurs, maintain normal water intake.

[0057] When the load of a certain end-of-pipe treatment plant is detected to exceed a preset threshold ( > When this occurs, the system executes the following coordinated scheduling strategy: (1) Open the connecting pipes that connect to other drainage areas to divert some of the water to other end-of-pipe treatment plants; (2) Adjust the strategy of the end-of-pipe sewage treatment plant's storage tank, and temporarily store the excess water in the storage tank until the load decreases before treating it. (3) Adjust the diversion ratio of the water distribution wells and control the flow rate of each production line entering the treatment plant to ensure that the load of each production line is balanced.

[0058] The water distribution well diversion ratio is dynamically calculated based on the real-time load of each production line, prioritizing the allocation of water to production lines with lower loads to achieve load balancing at the end-of-pipe treatment plant.

[0059] This embodiment details the implementation mechanism of cyclic optimization control and the method for handling missing data. In step S7, the system periodically executes steps S2 to S6 at a preset time interval to achieve cyclic optimization control of the integrated drainage area's plant, station, and network.

[0060] Cyclic optimization control ensures that the system can respond promptly to changes in rainfall, liquid level fluctuations, and load variations, dynamically adjusting the control strategy. Within each control cycle, the system recalculates rainfall intensity, determines the operating mode, updates target flow limits, and generates control recommendations based on the latest monitoring data, achieving closed-loop control of the drainage system.

[0061] The preset time cycle can be set to once per hour, meaning the complete control process is re-executed every hour. During rainfall, the cycle can be shortened to once every half hour or every 15 minutes as needed to improve system response speed.

[0062] For pumping stations that participate in the calculations but lack real-time monitoring data, the system uses the design parameters from the planning manual for calculations. The specific handling method is as follows: (1) For pumping stations without real-time flow data, the real-time number of pumps in operation, combined with the single pump flow rate in the design manual, shall be used as the basis for flow calculation. (2) For pumping stations without pump group status data, it is assumed that all pump groups are in an available state; (3) Pump stations without real-time liquid level data will not participate in system strategy generation; By employing the aforementioned methods for handling missing data, we can ensure that the system can still generate effective control strategies even when complete monitoring data is unavailable.

[0063] Compared with the prior art, the present invention has the following beneficial effects: Enhance system coordination capabilities: Break down information barriers between plants, stations, and networks to achieve global collaborative control across regions and facilities. Through end-point load sensing and automatic scheduling of connecting pipes, balance the treatment capacity of different areas, prevent wastewater treatment plants from operating under overload, and improve the overall system's operational resilience and risk resistance.

[0064] Achieve precise, tiered control: The system automatically switches operating modes (dry weather, light rain, moderate rain, heavy rain, and post-rain) based on rainfall intensity and dynamically adjusts target flow limits. This enables the system to adopt differentiated control strategies according to different operating conditions, ensuring normal delivery during dry weather while effectively controlling the risk of overflow during rainy weather.

[0065] Optimize equipment operating efficiency: Control pump start-up and shutdown by comparing flow increments with target limits, prioritizing pumps with the lowest flow rates to avoid sudden large flow surges impacting the pipeline network. Simultaneously, reduce ineffective pump start-ups and shutdowns, lower equipment wear and energy consumption, and extend facility lifespan.

[0066] Maximize the effectiveness of stormwater storage facilities: Establish a coordinated control mechanism between flood control pumps and stormwater storage tanks, prioritize the use of storage space for peak shaving and valley filling, and delay the start-up time of flood control pumps. After rainfall, release water in an orderly manner to ensure rapid recovery of storage capacity, significantly improving the capacity to regulate rainwater runoff and control pollution from combined sewer overflows.

[0067] Improve system response speed: Employ a periodic rolling optimization approach to enable the control strategy to continuously track system state changes and achieve closed-loop feedback control. Combined with a priority ranking mechanism for pump stations to be activated, ensure that limited pipeline capacity is prioritized for handling high-risk areas, thereby improving the accuracy and timeliness of emergency response.

[0068] Example 2 Embodiment 2 of this application includes all the technical features of Embodiment 1, such as Figure 2 As shown in Embodiment 2 of this application, an integrated operation and control method for drainage area plants and networks is provided, comprising the following steps: S10. Based on geographical features, the topological connection relationship of trunk and branch pipeline networks and the location of key node pumping stations, the drainage area, which includes sewage / combined sewer interceptor pumps, rainwater pump interceptor pumps, rainwater pump flood control pumps, combined / rainwater pump storage tanks, inter-area connecting pipes and end-of-area water distribution wells, is divided into several sub-areas. S20. Based on rainfall monitoring data in each sub-area, calculate the rainfall intensity and determine the current operating mode of the sub-area. The operating mode includes drought mode, light rain mode, moderate rain mode, heavy rain mode, and post-rain mode. S30. Determine the target traffic limit for the sub-area based on its current operating mode. S40. For each sub-area, based on the current operating mode, the start / stop liquid level threshold of the intercepting pump / intercepting pump and the target flow limit, generate the start / stop control strategy of the intercepting pump and the intercepting pump, and generate the linkage control strategy of the flood control pump and the regulating tank. S50. Based on the inflow rate and load rate of the end-of-pipe treatment plant, the excess water exceeding the load of the end-of-pipe treatment plant is diverted to other sub-area end-of-pipe treatment plants or temporarily stored in the storage tank. The diversion ratio of the end-of-pipe distribution wells in the area is adjusted, and a coordinated scheduling strategy for the end-of-pipe plant network is generated to coordinate and control the end-of-pipe distribution wells, end-of-pipe storage tanks, and connecting pipes connecting other sub-areas in the area. S60. The start-stop control strategy, the linkage control strategy, and the terminal plant network collaborative scheduling strategy are executed cyclically at a preset cycle to achieve rolling optimization control of the integrated plant network in the drainage area.

[0069] Among them, by dividing the drainage area into sub-areas, determining multiple operating modes based on rainfall monitoring data, determining the target flow limit of the sub-area according to different operating conditions, generating control strategies for the start and stop of intercepting sewage pumps and intercepting diversion pumps and the linkage between flood control pumps and regulating reservoirs, and carrying out coordinated water volume scheduling of terminal plants, stations and networks and performing optimized control in a preset cycle, it is possible to break down the information barriers between plants, stations and networks, realize the coordinated regulation of the entire system facilities, enable the drainage system to automatically adapt the control logic according to rainfall conditions, effectively balance the pipeline network's transmission capacity and the terminal treatment plant's processing load, reduce the risk of urban flooding and combined sewer overflow pollution, and improve the system's operational resilience, intelligence level and overall management efficiency.

[0070] Furthermore, the drainage area, which includes sewage / combined sewer interceptor pumps, stormwater interceptor pumps, stormwater flood control pumps, combined sewer / stormwater pump storage tanks, inter-area connecting pipes, and end-of-area distribution wells, is divided into several sub-areas, including: The criteria for dividing sub-regions include geographical boundary features, the topological connection relationship between trunk and branch pipeline networks, the location of key node pump stations, and the distribution of trunk pipelines from each sub-region to the terminal treatment plant. Based on the aforementioned sub-zone division criteria, the drainage zone, which includes sewage / combined sewer interceptor pumps, stormwater interceptor pumps, stormwater flood control pumps, combined sewer / stormwater pump storage tanks, inter-zone connecting pipes, and end-of-zone distribution wells, is divided into several independently controllable sub-zones.

[0071] By clearly defining the basis for sub-area division and dividing the area into independent control units based on the distribution of various drainage facilities within the area, the boundaries of drainage control units can be clearly defined and the control targets can be accurately identified. This provides a foundation for refined scheduling by region and unit, enhances the targeting and independence of scheduling in each sub-area, avoids mutual interference between different control units, and ensures the orderly and stable operation of the overall system.

[0072] Furthermore, the step of calculating rainfall intensity and determining the current operating mode of each sub-area based on rainfall monitoring data includes: Real-time rainfall data from each monitoring point is obtained, and the rainfall intensity at each monitoring point in the sub-area within a preset time interval is calculated using the formula I=∆R / ∆t; where, Rainfall intensity (mm / h) The cumulative rainfall over the period is in mm. The time interval is (h). When the proportion of rainfall with an intensity greater than 0.1 mm exceeds a preset threshold, it is identified as a rainfall event and the rain mode is entered; otherwise, it is determined that there is no valid rainfall signal. When the cumulative rainfall in 24 hours is less than or equal to 10 mm, it is determined to be a light rain pattern; when the cumulative rainfall in 24 hours is greater than 10 mm, it is determined to be a moderate rain pattern; when the cumulative rainfall in 24 hours is greater than 25 mm, it is determined to be a heavy rain pattern. When there is no effective rainfall signal, check whether there are historical rainfall event records within the preset time window. If there are historical rainfall records, it is determined to be a post-rain mode; if there are no historical rainfall records, it is determined to be a dry weather mode.

[0073] Among them, by calculating based on the rainfall intensity formula, determining the proportion of effective rainfall signals, classifying rainfall types by cumulative rainfall, and distinguishing between dry and post-rain patterns by combining historical rainfall records, the system can automatically, accurately, and quickly identify the operating mode, providing a reliable basis for subsequent differentiated control strategies, avoiding scheduling failures due to mode misjudgment, and improving the system's adaptive ability to rainfall changes.

[0074] Furthermore, determining the target traffic limit for the sub-region based on its current operating mode includes: In the dry weather mode, the target flow limit for the sub-area is the product of the average dry weather flow over the past three days and the dry weather mode coefficient. In the post-rain mode, the target flow limit for the sub-area is the product of the average flow of the past three dry days and the post-rain mode coefficient. In the light rain mode, the target flow limit for the sub-area is the product of the average flow of the past three dry days and the rainy day mode coefficient. In both moderate and heavy rain modes, the target flow limit for the sub-area is a preset fixed threshold.

[0075] Among them, by using coefficient product or fixed threshold methods to determine the target flow limit for different operating conditions such as dry weather, after rain, light rain, moderate rain, and heavy rain, the flow control of sub-areas can be highly matched with the actual operating conditions. This ensures stable sewage delivery during dry weather and constrains the upper limit of pipeline flow during rainy weather, avoiding pipeline overload and drastic fluctuations in treatment plant load, thus achieving dynamic and refined flow control.

[0076] Furthermore, the start-stop control strategy for generating the intercepting pump and the intercepting pump includes: In dry weather mode and post-rain mode, the liquid level difference is calculated and arranged in descending order based on the start-up and stop liquid level of the interceptor pump / interception pump and the real-time liquid level of each pump station. Pump stations with real-time liquid levels higher than the start-up water level of the interceptor pump / interception pump are included in the list to be opened, and pump stations with real-time liquid levels lower than the stop-up water level of the interceptor pump / interception pump are included in the shutdown strategy. The pump stations in the list to be activated are judged in order of arrangement. The real-time flow of the current sub-area and the flow increment of the intercepting pump with the minimum available nameplate flow are read. When the sum of the real-time flow and the flow increment is less than the target flow limit, the pump station is included in the activation strategy. Once the pump stations in the list to be activated have been identified, each pump station is controlled to activate at most one new pump in each activation strategy. In light rain, moderate rain, and heavy rain modes, the intercepting pumps of each pumping station generate and execute start-up and shutdown strategies according to the control methods used in dry weather and post-rain modes, and the intercepting pumps of each pumping station form shutdown strategies to shut down one by one.

[0077] Among them, by constructing a list of pump stations to be started according to the liquid level difference, controlling the start and stop of pumps by combining the flow increment of the minimum nameplate flow pump with the target flow limit, and implementing differentiated management and control of intercepting pumps and intercepting pumps in different modes, it is possible to avoid the impact of sudden flow surges on the pipeline network caused by concentrated pump start-ups, reduce ineffective pump start-ups and stops, reduce equipment wear and energy consumption, and at the same time ensure orderly and controllable sewage transportation and prevent the sewage pipeline network from overloading during rainy days.

[0078] Furthermore, the linkage control strategy for generating flood control pumps and regulating reservoirs includes: In dry weather mode and post-rain mode, flood control pumps are shut down one by one, and storage tanks are shut down or emptied. In light rain, moderate rain, and heavy rain modes, for flood control pumps without storage tanks, the start and stop are controlled based on the start / stop liquid level of the flood control pump forebay and the real-time liquid level of each pumping station. The flood control pump is activated when the current liquid level of the storage tank is higher than the flood control activation level, and the flood control pump is shut down when the current liquid level of the storage tank is lower than the flood control shutdown level. For flood control pumps equipped with storage tanks, the storage tanks are used to temporarily store rainwater, and the flood control pumps are activated after the utilization rate of the storage tanks reaches the saturation threshold.

[0079] Among them, by implementing differentiated control of flood control pumps and storage tanks in different modes, the storage tanks are used to temporarily store rainwater and the flood control pumps are started after the utilization rate reaches the saturation threshold. This can give full play to the peak shaving and valley filling role of the storage facilities, delay the start time of flood control pumps, reduce the pump running time, and improve the rainwater runoff regulation capacity and the combined overflow pollution control effect.

[0080] Furthermore, for the flood control pump equipped with a storage tank, the method of temporarily storing rainwater in the storage tank and activating the flood control pump after the storage tank reaches a saturation threshold includes: When using the stormwater storage tank to temporarily store rainwater, calculate the utilization rate of the stormwater storage tank and monitor the current liquid level of the stormwater storage tank in real time. If the current liquid level of the storage tank is higher than the flood control activation water level and the utilization rate of the storage tank has not reached the saturation threshold, the storage tank shall remain in the water intake state and the flood control pump shall remain closed. If the current liquid level of the storage tank is higher than the flood control activation level and the utilization rate of the storage tank reaches the saturation threshold, the water intake of the storage tank shall be stopped and the flood control pump shall be activated for drainage.

[0081] By quantifying the utilization rate of the storage tank and controlling the inflow of water into the storage tank and the start-up and shutdown of the flood control pumps according to the liquid level in the forebay and the utilization rate of the storage tank, precise linkage between the storage tank and the flood control pumps can be achieved, ensuring that the storage space is fully utilized, avoiding ineffective water storage in the storage tank or accidental start-up of the flood control pumps, and improving the stability and reliability of the coordinated operation of the facilities.

[0082] Furthermore, the coordinated scheduling strategy for the terminal water distribution wells, terminal storage tanks, and connecting pipes linking other sub-regions within the coordinated control area includes: After the rainfall event ends, the list of storage tanks to be emptied in the sub-area is obtained and formed. The list of storage tanks to be emptied is read, and the water discharge operation of the storage tanks is performed under the premise that the real-time flow rate in the sub-area does not exceed the target flow rate limit, until the water level of the storage tank drops to the minimum level, and then the water discharge is stopped.

[0083] By orderly emptying the storage tanks after rainfall ends, provided that the real-time flow in the sub-area does not exceed the limit, the effective storage capacity of the storage tanks can be quickly restored without affecting the normal operation of the pipeline network. This ensures that the storage facilities can be repeatedly used for subsequent rainfall regulation and continue to play a role in flood prevention and pollution control.
