Description

Technical Field

[0001] The present invention relates to the technical field of drainage system control, and in particular to a method, device and equipment for regulating the water level of an inner ditch river of a drainage system. Background Art

[0002] At present, with the deepening and gradual development of urbanization, the sewage treatment industry currently faces significant problems:

[0003] 1) Sewage treatment efficiency needs to be improved: According to industry statistics, the influent concentration of many sewage treatment plants is far lower than the designed concentration, resulting in the inability to fully utilize the treatment capacity. One of the main reasons is the dilution of the influent caused by problems such as pipe network infiltration, rainwater and sewage mixing, and backflow.

[0004] 2) Pipeline network management technology needs to be upgraded: At present, most urban pipeline inspections and renovations are still mainly done manually, which is a huge workload and inefficient. In particular, when faced with complex pipeline structures and dynamically changing hydrological conditions, traditional technical means can no longer meet the needs.

[0005] 3) Policy and standard upgrade requirements: As the country attaches great importance to the urban ecological environment, the policy clearly requires strengthening the construction and transformation of sewage pipe networks and improving sewage collection rates and treatment capabilities. This puts forward higher requirements for technologies such as drainage outlet backflow prevention, groundwater infiltration blocking, and rainwater and sewage diversion transformation.

[0006] The current drainage system usually relies on traditional monitoring and management methods to deal with problems such as backflow of discharge outlets, blocking of groundwater infiltration, and reconstruction of rainwater and sewage mixing. There are the following main deficiencies:

[0007] 1) Insufficient prevention and control of backflow at discharge outlets: Existing technologies for the prevention and control of backflow at discharge outlets mostly use fixed threshold alarms or manual inspections, lacking dynamic monitoring and accurate simulation capabilities. Problem manifestation: It is impossible to perceive the flooding of discharge outlets in real time, making it difficult to take prevention and control measures in a timely manner, resulting in serious backflow of rivers and lakes during droughts and high water levels in sewage pipes. Defects: The prevention and control strategy lags behind and cannot adapt to the complex hydrological conditions of the discharge outlets.

[0008] 2) Low efficiency in checking groundwater infiltration defects: Traditional methods rely on manual inspection of groundwater infiltration points, which is labor-intensive and time-consuming. Existing pipeline monitoring methods cannot accurately locate infiltration defects, resulting in a lack of targeted repair measures. Problem manifestation: Structural defects in sewage pipe networks cannot be detected quickly, and the amount of infiltration water is difficult to accurately assess. Defects: The detection method is not intelligent enough, and the repair priority ranking is unclear.

[0009] 3) Insufficient technical support for rainwater-sewage mixed connection transformation: The problem of rainwater-sewage mixed connection is complex. The existing technology lacks dynamic identification and evaluation tools, and it is difficult to provide personalized transformation solutions based on scenarios (such as street shops, communities or industrial parks). Problem manifestation: The identification of mixed connection points relies on a single data source, and the design of transformation solutions is difficult to meet diverse needs. Defects: The lack of simulation analysis functions makes it difficult to quantify and evaluate the transformation effect.

[0010] 4) Insufficient monitoring capability of sewage pipe network operation: Existing drainage system monitoring is usually based on a single indicator (such as water level or flow), which makes it difficult to achieve multi-dimensional comprehensive monitoring and linkage control. Problem manifestation: The analysis of abnormal operation of sewage pipe network (such as full pipe flow on dry days) and low influent concentration of sewage treatment plants is delayed, and it is impossible to quickly diagnose and deal with the problem. Defects: The monitoring methods are scattered and there is a lack of coordination between systems. Summary of the invention

[0046] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present invention and to enable the scope of the present invention to be fully communicated to those skilled in the art.

[0047] like Figure 1 As shown, an embodiment of the present invention provides a method for regulating the water level of an inner ditch river of a drainage system, comprising:

[0048] Step S1, obtaining the sluice water level data of Neigou River and the pipe point data related to the discharge outlet;

[0049] Step S2, determining the river water level line according to the sluice water level data;

[0050] Step S3, obtaining the flooding state of the discharge outlet according to the water level line of the river channel and the water level line of the discharge outlet;

[0051] Step S4, performing infiltration defect assessment on the pipe point data to obtain an infiltration defect assessment result;

[0052] Step S5, performing mixed connection defect assessment on the pipe point data to obtain a mixed connection defect assessment result;

[0053] Step S6, obtaining and displaying a backflow path analysis result according to the infiltration defect assessment result and the hybrid defect assessment result;

[0054] Step S7, controlling the gate opening of the sluice gate according to the flooding state of the discharge port and the backflow path analysis result.

[0055] In this embodiment, Figure 1As shown, in the method for regulating the water level of the inner ditch river in the drainage system, first, the water level data of the sluice of the inner ditch river and the pipe point data related to the discharge port are obtained. There are usually multiple sluices on the river channel of the inner ditch river, and each sluice is provided with a water level meter for monitoring the water level of the sluice; there are generally multiple pipe points in the drainage system, and the pipe points are key nodes or equipment in the drainage system. These nodes play an important role in the drainage system, mainly including various valves, inspection wells, rainwater grates, etc., which are used to control water flow, inspect and maintain the normal operation of the drainage system; then, the distribution law of water flow is used to determine the river channel according to the water level data of the adjacent two sluices. The water level line can obtain the water level height data of each point in the river; secondly, according to the river water level line and the discharge outlet water level line, the two data are compared to obtain the flooding state of the discharge outlet of the drainage system; thirdly, the infiltration defect assessment is performed on the pipe point data to obtain the infiltration defect assessment result; the mixed connection defect assessment is performed on the pipe point data to obtain the mixed connection defect assessment result; thirdly, according to the infiltration defect assessment result and the mixed connection defect assessment result, the two assessment results are superimposed and analyzed to obtain the backflow path analysis result and display it; finally, according to the flooding state of the discharge outlet and the backflow path analysis result, the gate opening of the sluice is controlled. The scheme of the present invention makes up for the defects of the prior art through a systematic and intelligent technical scheme, and provides a comprehensive and efficient solution path for the optimization of urban drainage systems.

[0056] In an optional embodiment of the present invention, the method for controlling the water level of an inner ditch river of a drainage system further includes:

[0057] Step S8, generating a manhole cover opening work order according to the flooding status of the discharge port.

[0058] In this embodiment, according to the flooding status of the discharge outlet, a manhole cover opening work order can be automatically generated, and then it is verified whether the discharge outlet is lower than the water level of the water body, and whether there is backflow on site is confirmed; the content of the manhole cover opening work order includes: discharge outlet location, discharge outlet number, simulated water level result, fault description, emergency status, processing status, operator, operation suggestions, etc. The work order is assigned to on-site maintenance personnel through the work order management module, and supports real-time viewing on mobile terminals. The operation and maintenance personnel conduct manhole cover opening inspections based on the content of the work order to confirm whether there is backflow, and upload the inspection results to the system.

[0059] In an optional embodiment of the present invention, in step S2, determining the river water level line according to the sluice water level data includes:

[0060] Step S21, sorting the sluice water level data according to the upstream and downstream order of the sluice;

[0061] Step S22, smoothing the data of two adjacent sluice gates to obtain a river water level line.

[0062] In this embodiment, water level observation data of the sluice at different time points is obtained from the sluice management department. The data should include accurate time stamps and corresponding water level values. For example, the water level values recorded regularly every hour or every day; basic information of the river channel is collected, such as the cross-sectional dimensions of the river channel, topographic data upstream and downstream of the sluice, etc. These information help to more accurately understand the relationship between water level changes and the river channel topography; according to the upstream and downstream order of the sluice, the water level data of the sluice is sorted in sequence from the upstream sluice to the downstream sluice. Generally speaking, due to the higher terrain in the upstream area, the water level is relatively low. As the water flows downstream, the water level will gradually rise. According to the basic information of the river channel and the distribution characteristics of the average water level in the inner ditch river, the data of two adjacent sluices are smoothed in sequence to determine and draw the river channel water level line.

[0063] In an alternative embodiment of the present invention, in step S3, according to the river channel water level line and the discharge port water level line, the submerged state of the discharge port is obtained, including:

[0064] Step S31, comparing the river channel water level line with the discharge port water level line to obtain the submerged state of the discharge port, and the submerged state of the discharge port includes full submersion, non-submersion or partial submersion.

[0065] In this embodiment, a water level gauge is installed at the discharge port to monitor the water level information at the discharge port in real time and upload the information to the platform. Preferably, this platform is a Geographic Information System (GIS). The GIS platform integrates map display and analysis functions, which is convenient to display location information in the form of a map;

[0066] Comparing the river channel water level line with the discharge port water level line, if the river channel water level line d at the discharge port is greater than or equal to the vertex height p1 of the discharge port, that is, d≥p1, then the discharge port is fully submerged at this time;

[0067] If the river channel water level line d at the discharge port is less than or equal to the bottom point height p2 of the discharge port, that is, d≤p2, then the discharge port is not submerged at this time;

[0068] If the river channel water level line d at the discharge port is greater than the bottom point height p2 of the discharge port and less than the vertex height p1 of the discharge port, that is, p2<d<p1, then the discharge port is partially submerged at this time;

[0069] If the discharge port is fully submerged or partially submerged, mark its position and output a prompt, and at the same time dynamically display the river channel water level line and the discharge port state on the GIS map;

[0070] Specifically, when calculating the water level height, when the calculation method is water depth: height = the measured value of this water level gauge + the river bottom elevation of this water level gauge; when the calculation method is air height: height = the 85 elevation RTK value of this water level gauge - the measured value of this water level gauge, where the RTK value is the measurement result of the real-time kinematic positioning technology;

[0071] If the river water level line ≥ the discharge outlet cross-sectional size + discharge outlet bottom elevation, it is judged to be submerged;

[0072] If the river water level is ≤ the discharge outlet bottom elevation, it is considered not flooded;

[0073] If the discharge outlet bottom elevation < river water level < discharge outlet cross-sectional dimensions + discharge outlet bottom elevation, it is considered to be semi-submerged;

[0074] When using RTK technology to measure 85 elevation, elevation conversion is required. The conversion process usually involves the following steps: 1. RTK measurement: Use RTK equipment to measure and obtain the geodetic height data of the point to be measured. 2. Elevation anomaly calculation: According to the elevation anomaly map of the survey area or using the elevation anomaly calculation tool, calculate the elevation anomaly value of the point to be measured. The elevation anomaly value is the difference between the geodetic height and the normal height. 3. Elevation conversion: Subtract the elevation anomaly value from the geodetic height to obtain the 85 elevation of the point to be measured.

[0075] In an optional embodiment of the present invention, in step S4, the infiltration defect assessment is performed on the pipe point data to obtain an infiltration defect assessment result, including:

[0076] Step S41, performing an abnormality analysis on the pipe point data to obtain an abnormality analysis result; the abnormality analysis includes flow baseline analysis and pollutant concentration analysis;

[0077] Step S42, performing infiltration point detection according to the abnormality analysis result to obtain infiltration point parameters;

[0078] Step S43, scoring the infiltration points according to the infiltration point parameters to obtain an infiltration defect assessment result.

[0079] The specific implementation may include: first, collecting the time series data of drainage flow, which is collected at fixed time intervals (e.g., every hour) over a period of time (e.g., one day, one week, one month, or longer). Suppose we have a set of drainage flow data Qi = {q1, q 2 ,…,qn}, where qi represents the drainage flow at the i-th time point, and n is the total number of data points; calculate the mean Q′ of this set of data, For example, the flow rate of the existing 5 drainage flow data points is 10m 3 / h,12m 3 / h,8m 3 / h,11m 3 / h,9m 3 / h, use the following formula to calculate the standard deviation:

[0080]

[0081] The standard deviation σ is 1.41m. 3 / h; standard deviation is of great significance in drainage flow baseline analysis. It can measure the degree of dispersion of drainage flow data relative to the mean. A smaller standard deviation means that the drainage flow is relatively stable, and most data points are concentrated near the mean; while a larger standard deviation means that the drainage flow fluctuates greatly and the data is more scattered. When formulating a drainage flow baseline, the mean can be used as the central reference value, and the standard deviation is used to determine a reasonable fluctuation range. For example, a standard deviation of a certain multiple of the mean (such as 1-3 times) can be used as the normal range of drainage flow, that is, the baseline range; for example, if the average daily flow of a pipeline node is 100m 3 / h, standard deviation is 10m 3 / h, then the baseline range can be set to [70m 3 / h, 130m 3 / h]; if the drainage flow exceeds this range, the standard deviation of the flow suddenly increases, exceeding the normal fluctuation range, which may also indicate the existence of infiltration points, because infiltration may increase the uncertainty of drainage flow and make the flow data more discrete.

[0082] In this embodiment, the inspection wells and other pipe points area related to the discharge outlet are selected, the inspection wells and other pipe points are marked on the GIS map, and the system automatically loads the relevant inspection wells, pipe points and their upstream and downstream data, and the system performs infiltration defect assessment on the upstream and downstream pipe points;

[0083] Infiltration defects refer to the problem of external water (such as groundwater or surface water) entering the drainage network through damaged pipes, loose joints or other defects; prepare the data required for infiltration defect assessment, pipeline status monitoring: use pipeline closed-circuit television (CCTV) detection system or pipeline robot to collect images of the inside of the pipeline, check for defects such as cracks, damage or loose joints; water level and flow monitoring: monitor the water level and flow in the pipeline network on dry days to determine the source of abnormal water volume; groundwater level monitoring: measure the groundwater level through inspection wells to determine the risk of groundwater infiltration through damaged pipe sections; after obtaining basic data, first conduct anomaly analysis, including flow baseline analysis: establish a dry day flow baseline under normal operation of the pipeline network, compare the actual monitored value with the baseline value to determine whether there is an abnormal increase; pollutant concentration Degree monitoring: test water quality indicators (such as chemical oxygen demand, suspended solids, ammonia nitrogen, etc.), low pollution concentrations may indicate the presence of infiltration; conduct infiltration point detection again to locate the infiltration point, dye or tracer experiment: inject dye or tracer into the suspicious area to observe whether it is detected in the pipe network; sonar detection: use sound wave reflection technology to scan the pipeline to locate possible damage or leakage points; smoke test: inject harmless smoke through the pipe network to observe whether it enters the pipe network from surface or groundwater, and obtain infiltration point parameters; finally, conduct quantitative assessment of infiltration defects, flow model analysis: combine monitoring data with pipe network model to calculate infiltration volume and its impact on pipe network; defect scoring system: assign a score to each defect point according to the severity of the defect, infiltration volume and its impact on system operation, and obtain the infiltration defect assessment result.

[0084] In an optional embodiment of the present invention, in step S5, the pipe point data is subjected to a mixed connection defect assessment to obtain a mixed connection defect assessment result, including:

[0085] Step S51, obtaining a mixed area according to the pipe point data;

[0086] Step S52, tracing the hybrid area to obtain the hybrid type;

[0087] Step S53: Perform an impact analysis according to the hybrid type to obtain a hybrid defect assessment result.

[0088] The specific implementation may include: first, collecting the time series data of drainage flow, which is collected at fixed time intervals (such as every hour) over a period of time (such as a day, a week, a month or longer). Suppose we have a set of drainage flow data Q i = {q 1 ,q 2 ,…,q n}, where q i represents the drainage flow at the i-th time point, n is the total number of data points; calculate the mean Q′ of this set of data, For example, the flow rate of the existing 5 drainage flow data points is 10m 3 / h,12m 3 / h,8m 3 / h,11m 3 / h,9m 3 / h, use the following formula to calculate the standard deviation:

[0089]

[0090] The standard deviation σ is 1.41m. 3 / h; standard deviation is of great significance in drainage flow baseline analysis. It can measure the degree of dispersion of drainage flow data relative to the mean. A smaller standard deviation means that the drainage flow is relatively stable, and most data points are concentrated near the mean; while a larger standard deviation means that the drainage flow fluctuates greatly and the data is more scattered. When formulating a drainage flow baseline, the mean can be used as the central reference value, and the standard deviation is used to determine a reasonable fluctuation range. For example, a standard deviation of a certain multiple of the mean (such as 1-3 times) can be used as the normal range of drainage flow, that is, the baseline range; for example, if the average daily flow of a pipeline node is 100m 3 / h, standard deviation is 10m 3 / h, then the baseline range can be set to [70m 3 / h, 130m 3 / h]; if the drainage flow exceeds this range, the standard deviation of the flow suddenly increases, exceeding the normal fluctuation range. Under normal circumstances, the flow of the sewage pipe is mainly affected by the discharge of domestic sewage and industrial sewage, and is relatively stable; the flow of the rainwater pipe is closely related to the rainfall. If there is a continuous flow in the rainwater pipe without rainfall, or the flow of the sewage pipe does not change significantly on rainy days, there may be a mixture; because mixing may increase the uncertainty of the drainage flow and make the flow data more discrete. At the same time, monitor the water quality parameters (such as chemical oxygen demand, pH, etc.) and flow in the drainage pipe. The water quality parameters of sewage and rainwater are usually significantly different. If a high concentration of sewage water quality indicators is detected in the rainwater pipe and the flow is abnormal, it can be inferred that there is a mixture. For example, if the chemical oxygen demand is found to exceed the standard in the rainwater pipe and the flow is stable, it may be that the sewage pipe is connected to the rainwater pipe.

[0091] In this embodiment, the inspection wells and other pipe points related to the discharge outlet are selected, and the inspection wells and other pipe points are marked on the GIS map. The system automatically loads the relevant inspection wells, pipe points and their upstream and downstream data, and the system conducts mixed connection defect assessment on the upstream and downstream pipe points; mixed connection defects refer to the problem of rainwater pipes, industrial wastewater or illegal drainage points being mistakenly connected to the sewage pipe network. Prepare the data required for mixed connection defect assessment, pipeline flow and water quality monitoring: monitor water quality parameters such as turbidity, chemical oxygen demand, total phosphorus, etc. under different weather conditions (dry days, rainy days) to determine whether there is abnormal pollution in the pipe network; compare water consumption and drainage: by comparing water consumption records with drainage records, the source of abnormal drainage can be found.

[0092] According to the basic data obtained, first determine the mixing area, and measure the flow section by section: install flow meters in different sections of the pipe network to narrow the location range of the mixing defects; dyeing experiment: inject dye into the rainwater pipe or suspicious drainage outlet to observe whether it appears in the sewage pipe; drone inspection: drone inspection of ground rainwater wells and drainage outlets to check for illegal access points. Then, identify the type of mixing, industrial pollution detection: detect the concentration of specific pollutants (such as heavy metals, volatile organic compounds, etc.) to determine whether there is industrial wastewater access; rainwater mixing identification: identify the possible source of rainwater access through rainy day flow monitoring; domestic sewage mixing identification: detect indicators such as biochemical oxygen demand (BOD) and fecal coliform group to identify the wrong access of domestic sewage. Finally, conduct an impact analysis and pollution load calculation: combine water volume and pollutant concentration to quantify the load impact of mixing defects on sewage treatment plants; impact zoning analysis: use the GIS system to mark the mixing points on the map to evaluate its impact on the upstream and downstream pipe networks. At the same time, combined with the longitudinal section function of the GIS map, the inspection wells, pipe points, pipelines, mixed connection defects and water level information of the water level gauge are superimposed to provide multi-dimensional visual analysis; 1) Longitudinal section generation: Select the relevant inspection wells in the discharge port area in the GIS map, and the system will generate a regional longitudinal section view. 2) Multi-dimensional data superposition: The inspection well location, pipe points, pipelines, mixed connection defects and water level information of the water level gauge are superimposed on the longitudinal section view to intuitively display the operation status of the pipeline network. 3) Supports exporting longitudinal section screenshots for subsequent analysis and report preparation.

[0093] In an optional embodiment of the present invention, in step S7, controlling the gate opening of the water gate according to the flooding state of the discharge port and the backflow path analysis result includes:

[0094] Step S71, according to the preset joint adjustment strategy, the gate opening of the water gate is controlled according to the flooding state of the discharge port and the backflow path analysis results.

[0095] In this embodiment, the sluice gate is connected to a monitoring and data acquisition system (SCADA) through a programmable logic controller (PLC). The SCADA system collects equipment operation status and attribute data, collects pipe network water level, water volume and water quality data in real time through sensors, performs multi-dimensional analysis on the monitoring data, identifies operation anomalies (such as full pipe flow on dry days, abnormal influent concentration), and controls the gate opening of the sluice gate according to the flooding status of the discharge port and the analysis results of the backflow path according to the preset joint adjustment strategy;

[0096] In the present invention, the joint discharge and coordination strategy adopted by the system is as follows: during high water level period (river and lake water levels are higher than the discharge port elevation): automatically close the sluice gate corresponding to the discharge port to prevent river and lake water from backflowing, and guide the sewage in the pipe network to be discharged through other unaffected discharge ports or storage tanks; during low water level period (river and lake water levels are lower than the discharge port elevation): automatically open the sluice gate to increase discharge efficiency, release pipe network pressure, dynamically adjust the opening ratio, and ensure that the downstream processing capacity is not overloaded; in extreme weather (heavy rain or tidal superposition): close all discharge ports that are susceptible to backflow in advance, start emergency storage in the storage tank, link the scheduling capacity of the sewage treatment plant, and improve processing efficiency.

[0097] In the present invention, the coupling relationship between the inland river water level, gate regulation, and sewage treatment plant influent water quality is as follows:

[0098] 1. Coupling relationship between inland river water level and sewage treatment plant influent quality

[0099] It not only ensures that the influent concentration of the sewage treatment plant meets the treatment efficiency requirements, but also avoids the phenomenon of black and smelly water due to the low water level of the inland river. Adjust the gate opening at different water levels, measure the corresponding influent water quality and river water quality, and gradually optimize the balance point between the two. Set the minimum water level threshold of the inland river (to avoid black and smelly water); set the target value range of the influent concentration of the sewage treatment plant (to ensure treatment efficiency).

[0100] 2. Coupling relationship between inland river water level and gate regulation

[0101] By dynamically adjusting the gate opening, the water level of the inland river is kept within a reasonable range, while avoiding the dilution of sewage concentration by excess water. When the water flow in the upper reaches of the river decreases, the gate opening is appropriately reduced to maintain a stable water level; when the flow of the drainage network increases significantly, the gate opening is increased to reduce the pressure on the network. In conjunction with the water level sensor data, real-time feedback adjustment of the gate opening is achieved.

[0102] 3. Coupling relationship between sewage treatment plant influent quality and gate regulation

[0103] According to the treatment capacity of the sewage treatment plant and the requirements of the influent water quality, the gate opening is dynamically adjusted to ensure that the sewage concentration is within the ideal range. When the influent concentration is too low, the gate opening is appropriately reduced to reduce the amount of dilution water; when the influent concentration is too high, the gate opening is appropriately increased to ensure safe operation. In combination with the daily treatment capacity of the sewage treatment plant, the upper and lower limits of the gate opening are set to avoid overload operation or too low water concentration. When the influent water quality is monitored to exceed the set range, the gate opening is adjusted in conjunction and a control alarm signal is issued.

[0104] The specific implementation process of the above method of the present invention is described below with an example:

[0105] The drainage network of a certain city is connected to the river and lake system. During heavy rains and peak tidal periods, the water levels of rivers and lakes are often higher than the elevation of the discharge outlets, causing river and lake water to flow back into the drainage network, resulting in the network being overloaded and the sewage treatment plant having a serious dilution effect, affecting the city's flood control capabilities and water environment quality.

[0106] To improve this problem, the city introduced SCADA and discharge port linkage control technology, combining real-time monitoring and joint scheduling strategies to dynamically control the discharge port water level and the opening and closing status of the sluice gate.

[0107] 1. System Integration

[0108] SCADA system: connected to all drainage networks and sluice equipment in the city, collecting data in real time, including water levels at discharge outlets, water levels in rivers and lakes, and flow in the network.

[0109] PLC equipment: controls the opening and closing of the sluice gate and accepts remote control commands from the SCADA system.

[0110] Discharge outlet monitoring equipment: install water level sensors and flow meters to achieve real-time dynamic monitoring of the discharge outlet.

[0111] 2. Data Collection and Analysis

[0112] Real-time data collection:

[0113] River and lake water levels: Monitor river and lake water level changes through sensors and upload them to the SCADA system in real time.

[0114] Water level at the discharge outlet: monitor water level changes to determine whether it is in a flooded state.

[0115] Drainage network flow: Monitor the operating load of the drainage network through flow meters.

[0116] Data Analysis:

[0117] Use water level inundation simulation to analyze the changing trend of water levels at the discharge outlet and predict the risk of backflow.

[0118] Dynamically adjust control strategies based on weather forecast data (such as heavy rain warnings).

[0119] 3. Generation of joint scheduling strategy

[0120] Based on the collected real-time data, the SCADA system automatically generates the following joint operation and coordination strategies:

[0121] During high water level period (water level of rivers and lakes is higher than the elevation of the discharge outlet): automatically close the sluice gates corresponding to the discharge outlet to prevent backflow of river and lake water. Guide the sewage in the pipe network to be discharged through other unaffected discharge outlets or storage tanks. During low water level period (water level of rivers and lakes is lower than the elevation of the discharge outlet): automatically open the sluice gates to increase discharge efficiency and release the pressure of the pipe network. Dynamically adjust the opening ratio to ensure that the downstream processing capacity is not overloaded. In extreme weather (heavy rain or tidal superposition): close all discharge outlets susceptible to backflow in advance and start emergency storage in the storage tank. Link the dispatching capacity of sewage treatment plants to improve processing efficiency.

[0122] The operating results are as follows: Successfully prevented backflow: Under weather conditions of heavy rainfall and tidal peak, the SCADA system closed the sluice gates of 8 key discharge outlets based on real-time data, preventing river and lake water from backflowing into the drainage network.

[0123] Optimize drainage efficiency: When the tide recedes after rain, the system automatically opens the sluice gates to quickly drain water from the pipe network, avoiding urban waterlogging.

[0124] Improve the efficiency of sewage treatment plants: Through precise control, the influent concentration entering the sewage treatment plant has increased by 20%, and the treatment efficiency has been significantly improved.

[0125] Through the intelligent linkage control of the SCADA system and the sluice gate, combined with real-time data to generate joint drainage and coordination strategies, it is possible to accurately prevent and control backflow under different hydrological conditions, optimize the operating efficiency of the drainage system, and effectively improve the downstream water environment quality.

[0126] The solution of the present invention is based on the GIS smart drainage system, combined with the water affairs brain platform, to complete the water level monitoring and optimization regulation of Neigou River, forming a full-chain linkage management system of "Neigou River-sluice group-sewage treatment plant", which specifically includes the following contents: 1) Online monitoring of Neigou River water level: Supplement and optimize the water level monitoring along the Neigou River, including the installation of new water level gauges in the river, data docking of existing water level monitoring equipment, and conversion of monitoring values ​​with national 85 elevation values. By real-time collection and uploading of river water level data, a "water level map" based on GIS is constructed to provide data support for water level regulation and joint operation. 2) Gate opening and operating water level regulation: During the trial operation of the Neigou River water level drop, the sluice equipment is connected through the SCADA system to regulate the gate opening, dynamically adjust the water level of Neigou River, and accumulate the coupling relationship between the water level and the influent quality of the sewage treatment plant. Optimize the joint operation strategy under sunny working conditions, realize the linkage of the gate group, and improve the operation accuracy. 3) Monitoring and optimization of water quality entering the sewage treatment plant: Real-time collection of water quality concentration data entering the sewage treatment plant, dynamic analysis of the effect of water level drop on the improvement of water quality entering the sewage treatment plant, and finding the optimal operating conditions. Linking the regulation of Neigou River with the operation of the sewage treatment plant provides a decision-making basis for improving quality and efficiency. 4) Abnormal situation monitoring and work order management: Abnormal warnings for water level, sewage concentration and the black and smelly state of Neigou River, automatic generation of work orders, and distribution to relevant maintenance personnel for disposal. Combined with GIS maps, rapid location of problems can be achieved to ensure timely response to abnormal problems. 5) Operation analysis and report generation: Integrate water level control data, sewage treatment plant operation data and abnormal handling records, generate monthly and daily reports, and provide managers with comprehensive operation analysis reports. Provide a cockpit interface to visualize operation indicators and control results.

[0127] The advantages of the present invention are as follows: 1) A GIS-based intelligent drainage map constructs a comprehensive visualization platform for drainage network, inner ditch river water level, and sewage treatment plant operation data, realizing closed-loop management from "problem discovery" to "linked disposal". 2) Coupling analysis of inner ditch river water level and sewage treatment plant water quality: By accumulating water level control and sewage treatment plant inlet water quality data, a set of optimal sunny day operating plans are formed, providing a scientific basis for future joint drainage and coordination in the entire city. 3) Supplementary water level monitoring and data docking: Add water level gauges to rivers that do not have monitoring conditions, and standardize the water level data of intelligent interception wells to improve data quality and reliability.

[0128] The beneficial effects of the present invention are as follows: 1) Improved drainage efficiency: The water level of Neigou River is precisely regulated, the water quality concentration entering the sewage treatment plant is increased by about 15%, and the sewage collection efficiency is significantly improved. 2) Improved water environment: While ensuring that the water level of Neigou River is lowered, the black and smelly phenomenon is avoided, and the water environment quality of the urban inner river is improved. 3) Intelligent regulation: A gate group linkage regulation system is constructed to reduce manual operations and improve regulation accuracy and response speed. The system has created a refined, dynamic, and intelligent drainage management mode for the drainage system, providing a solution for improving the water quality of Neigou River and optimizing the drainage system.
