Description

Technical Field

[0001] This application relates to the field of pipeline leakage monitoring technology, and in particular to a method, system, electronic device and storage medium for locating leakage in water supply pipelines. Background Technology

[0002] Water scarcity poses numerous challenges to the socio-economic landscape. Leaks in water supply networks not only waste water resources and affect water quality but also reduce the operational efficiency of the water supply system, thereby increasing supply costs. Therefore, leakage analysis of water supply networks can, to a certain extent, assess leakage risks and determine leakage locations and extent, thus optimizing water supply management strategies and measures and contributing to the sustainable use of water resources and the sustainable development of the socio-economic system. Current research on leakage location in water supply networks mainly falls into three categories. The first category involves the design of physical hardware and mechanical devices, deploying equipment within the pipelines for real-time monitoring of leakage. The second category utilizes numerical analysis methods (correlation coefficients, cluster analysis, etc.) and artificial intelligence algorithms (convolutional neural networks, random forests, etc.) to train and simulate models based on measured data, thereby obtaining preliminary leakage locations. The third category uses hydraulic models to simulate the flow parameters of monitoring nodes, continuously changing operating scenarios and boundary conditions for iterative simulations, thereby narrowing down the range of leakage locations.

[0003] Although the technologies and equipment proposed in existing research have high engineering application value, their design and deployment costs are high, their economic practicality is low, and they are not easy to promote. The results obtained from simulations based on numerical analysis and machine learning algorithms are highly dependent on the sample and have a high technical threshold. On the other hand, repeated simulations using hydraulic models are inefficient and their accuracy is also questionable. Therefore, how to improve the accuracy of the location of leaking pipe sections is an urgent problem to be solved. Summary of the Invention

[0004] The main purpose of this application is to overcome the shortcomings and deficiencies of the prior art and provide a method, system, electronic device and storage medium for locating water supply pipeline leaks. By combining the water flow direction and leakage score in the leaking pipe section, the source can be traced to the location of the leaking pipe section, which can quickly, efficiently and more accurately locate the leak.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] In a first aspect, this application provides a method for locating leaks in water supply pipelines, comprising the following steps:

[0007] Obtain geographic information data of the water supply network and establish the topology of the water supply network based on the geographic information data;

[0008] The node parameters of the water supply network are simulated using a pre-built hydraulic model to obtain the simulated values ​​of the node parameters;

[0009] The simulated values ​​and measured values ​​are compared to obtain the difference values ​​of the parameters at each node;

[0010] Based on the aforementioned difference values, the leakage rate of the water supply network is assessed to obtain the leakage rate assessment results;

[0011] Based on the leakage rate assessment results, the direction of water flow in the leaking pipe section is determined, and the location of the leakage is traced by combining the score of the pipe section.

[0012] As a preferred technical solution, the geographic information data includes the location of pipeline networks, pumping stations, water tanks, and water sources;

[0013] The topology is established based on the connection relationships between the locations of the pipeline network, pump stations, water tanks, and water sources.

[0014] As a preferred technical solution, the step of simulating the node parameters of the water supply network using a pre-constructed hydraulic model to obtain simulated values ​​of the node parameters specifically includes:

[0015] The maximum water consumption of users is obtained as the boundary condition of the hydraulic model. Hydraulic calculations are performed on the pipe network according to the principles of hydraulics to obtain the simulated values ​​of the parameters of each monitoring node of the water supply pipe network under full water volume.

[0016] The node parameters include flow rate parameters, pressure parameters, water level parameters, and water quality parameters.

[0017] As a preferred technical solution, the method further includes normalizing the difference values ​​of the parameters of each node, and summing the normalized difference values ​​of each node parameter to obtain the difference value of each node.

[0018] As a preferred technical solution, the leakage rate assessment of the water supply network is performed based on the difference value to obtain the leakage rate assessment result, specifically:

[0019] Based on the difference values ​​of each monitoring node, the pipe segments connected to the nodes are assigned the same score, while the pipe segments between adjacent nodes are assigned the score based on the maximum difference value.

[0020] The leakage rate of the water supply network is assessed based on the scores of each pipe section. All pipe sections are ranked from highest to lowest score, and the leakage rate is divided into five levels to obtain the final leakage rate assessment result.

[0021] As a preferred technical solution, the direction of water flow is determined based on the measured pipeline elevation, water level, and water quality at each monitoring node;

[0022] The determination based on the pipeline elevation refers to the situation where, within the same pipeline section, water flows from one higher end to one lower end.

[0023] The water level determination refers to judging the water surface elevation by combining water level data and pipe bottom elevation data, and the water body flows from the end with a higher water surface to the end with a lower water surface.

[0024] The water quality assessment refers to the fact that the concentration of pollutants is high at the leak point, and the sewage flows from the location with high pollution concentration to the location with low pollution concentration.

[0025] As a preferred technical solution, the process of determining the water flow direction within the leaking pipe section and tracing the leak location based on the pipe section's score involves the following steps:

[0026] In pipe sections with high leakage rates, the pipe sections and nodes at the leakage points are located upstream, and the water flow direction will first pass through the upstream position; in addition, the pipe section with the highest score is located at the leakage point; therefore, by tracing the pipe section and node at the leakage point based on the water flow direction and the score of the pipe section, the location of the leakage pipe section can be further determined.

[0027] Secondly, this application provides a water supply pipeline leakage location system, which is applied to the aforementioned water supply pipeline leakage location method, including a topology structure establishment module, a simulation value module, a difference value module, a leakage rate assessment module, and a leakage location tracing module.

[0028] The topology establishment module is used to acquire geographic information data of the water supply network and establish the topology of the water supply network based on the geographic information data.

[0029] The simulation value module is used to simulate the node parameters of the water supply network using a pre-built hydraulic model, and obtain the simulated values ​​of the node parameters.

[0030] The difference value module is used to compare the simulated value and the measured value to obtain the difference value of each node parameter;

[0031] The leakage rate assessment module is used to assess the leakage rate of the water supply network based on the difference value, and obtain the leakage rate assessment result.

[0032] The leakage location tracing module is used to determine the water flow direction in the leaking pipe section based on the leakage rate assessment results, and to trace the leakage location in combination with the pipe section's score.

[0033] Thirdly, this application provides an electronic device, the electronic device comprising:

[0034] At least one processor; and,

[0035] A memory communicatively connected to the at least one processor; wherein,

[0036] The memory stores computer program instructions that can be executed by the at least one processor, which are executed by the at least one processor to enable the at least one processor to perform the water supply pipeline leakage location method.

[0037] Fourthly, this application provides a computer-readable storage medium storing a program, which, when executed by a processor, implements the aforementioned method for locating leaks in a water supply pipeline.

[0038] In summary, compared with the prior art, the effective effects of the technical solution provided in this application include at least the following:

[0039] This application combines hydraulic models with some measured data to conduct simulations and analyses, requiring minimal investment in monitoring equipment and manpower. The method is simple, feasible, low-cost, and highly applicable. Secondly, by comparing the simulated node parameter values ​​of the hydraulic model with the measured water flow parameters, high leakage rate pipe sections are identified. Furthermore, by combining the upstream and downstream characteristics of the water flow parameters, the direction of water flow in the pipe section is determined, thereby further tracing the source to the leakage section.

[0044] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort are within the scope of protection of the present application.

[0045] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0046] Please see Figure 1 One embodiment of this application provides a method for locating leaks in a water supply pipeline, comprising the following steps:

[0047] S1. Obtain geographic information data of the water supply network and establish the topology of the water supply network based on the geographic information data;

[0048] Furthermore, geographic information data is obtained from the water supply system, including the location of the pipeline network, pumping station, water tank, and water source; the topology refers to the establishment of the pipeline network topology based on the connection relationships of the pipeline network location, pumping station location, water tank location, and water source location.

[0049] In this embodiment, it is also necessary to determine the geometry of the pipeline network, pipe properties, and pipeline elevation. Pipeline properties include pipe diameter, material, coefficient of friction, and wall roughness. Pipeline elevation refers to the elevation value of the nodes to which the pipeline connects in the pipeline project. In addition, sensors will be deployed at key nodes of the water supply network to monitor parameters such as flow rate, pressure, water level, and water quality at each node in real time.

[0050] S2. Simulate the node parameters of the water supply network using a pre-built hydraulic model to obtain the simulated values ​​of the node parameters. The steps are as follows: determine the operation strategy (such as the location of water source and pump station, valve opening and closing control, etc.) based on the actual working conditions to allocate simulated water volume to the network, obtain the maximum water consumption of users as the boundary conditions of the hydraulic model, and perform hydraulic calculations on the network according to the principles of hydraulics to obtain the simulated values ​​of the water flow parameters of each monitoring node of the network under full water volume conditions.

[0051] In this embodiment, when constructing the hydraulic model, it is necessary to compare the topology, attribute parameters, connectivity, etc. of the water supply network with the actual situation, and on this basis, to conduct preliminary verification and correction of the hydraulic model to ensure that the model is as close to reality as possible.

[0052] Furthermore, the hydraulic model in this embodiment is based on the geographic information data and topology of the water supply system, and uses mainstream hydrological analysis software (modeling platforms such as SWMM, Infoworks, and WaterGEMS) to establish a hydraulic model of the water supply system under ideal conditions.

[0053] S3. Compare the simulated values ​​and measured values ​​to obtain the difference values ​​of each node parameter. The specific steps are as follows:

[0054] The flow rate, pressure, water level, and water quality of each monitoring node under ideal conditions were calculated using a hydraulic model. These parameters were then compared with the measured data at the corresponding time (the time of day with the highest water consumption) and at the corresponding node to obtain the difference values ​​of each parameter at each monitoring node.

[0055] In this embodiment, when the water supply network is in a leaky state, the actual measured values ​​of flow rate, pressure and water level are all lower than the values ​​under ideal conditions. Therefore, when the actual measured node parameter values ​​are generally greater than the simulated values ​​of the hydraulic model, the hydraulic model needs to be corrected.

[0056] Furthermore, since the units and scales of the parameter differences between nodes are inconsistent, it is necessary to normalize them. This embodiment uses the flow difference value as an example; the normalization calculation formula is as follows: Where Li represents the flow difference between each monitoring node, Lmax and Lmin represent the maximum and minimum differences among all monitoring nodes, respectively, and the value of L ranges from 0 to 1. Finally, the normalized difference values ​​of the four parameters for each monitoring node are summed to obtain a unique difference value for each monitoring node.

[0057] S4. Based on the difference value, assess the leakage rate of the water supply network to obtain the leakage rate assessment result;

[0058] Furthermore, the larger the difference value, the more the current state of the pipe segment associated with the monitoring node deviates from the ideal state, that is, the pipe segment is in an abnormal state and there is a risk of leakage.

[0059] Please see Figure 2 Based on the unique difference value of each monitoring node, the pipe segments connected to the nodes are assigned the same score, while the pipe segments between adjacent nodes are assigned the score based on the largest difference value (e.g., ...). Figure 2 The pipe section between nodes A and B (its score is the difference in value between nodes B and A) is used to assess the leakage rate of the water supply network based on the scores of each pipe section. All pipe sections are ranked from highest to lowest score, and the leakage rate is divided into five levels. The top 20% (inclusive) of pipe sections are rated as high leakage rate; the top 20%–40% (inclusive) are rated as relatively high leakage rate; the top 40%–60% (inclusive) are rated as medium leakage rate; the top 60%–80% (inclusive) are rated as relatively low leakage rate; and the pipe sections ranked below 80% are rated as low leakage rate. Based on the leakage rate assessment results, it is necessary to conduct irregular inspections of pipe sections with medium and high leakage rates. In particular, it is necessary to further locate and repair leaks in high leakage rate sections. Assume… Figure 2If the pipe sections associated with nodes B and D are identified as high leakage rate sections, the next step will focus on conducting leakage location research on them.

[0060] In this embodiment, it is assumed that Figure 2 The difference between the simulated and measured values ​​of the hydraulic model at node A is 2, at node B it is 4, at node C it is 1, and at node D it is 3. Therefore, based on assigning the pipe segment between adjacent nodes the maximum difference value, the pipe segment between nodes A and B is assigned a score of 4 (difference value of node B); the pipe segment between A and C is assigned a score of 2 (difference value of node A); the pipe segment between B and D is assigned a score of 4 (difference value of node B); and the pipe segment between C and D is assigned a score of 3 (difference value of node D).

[0061] S5. Based on the leakage rate assessment results, determine the water flow direction within the leaking pipe section, and trace the leakage location using the pipe section's score. Specifically, this includes:

[0062] Furthermore, to reduce the impact of hydraulic model uncertainties on the scoring of monitoring nodes and pipe sections, and to improve the accuracy of pipe section leakage location, this embodiment determines the water flow direction based on the measured pipeline elevation, water level, and water quality at each monitoring node: Based on pipeline elevation, water flows from the higher end to the lower end within the same pipe section; based on water level, water flows from the higher end to the lower end by combining water level data and pipe bottom elevation data; and based on water quality, sewage flows from the location of high pollution concentration to the location of low pollution concentration at the leakage point where the pollutant concentration is high.

[0063] In pipe sections with high leakage rates, the pipe sections and nodes closest to the leakage point are located upstream, and the water flow direction will first pass through the upstream position; furthermore, the closer the pipe section is to the leakage point, the higher its score; therefore, by tracing back to the pipe section and node closest to the leakage point based on the water flow direction and the pipe section score, the location of the leakage pipe section can be further pinpointed. Figure 2 As shown, the pipe segments associated with nodes B and D are high leakage rate segments. By comparing the scores and water flow direction of the associated pipe segments B and D, the location of the leakage segment closest to node B can be traced.

[0064] In summary, this application mainly combines hydraulic models with some measured data to conduct simulation and analysis, which does not require much investment in monitoring equipment and manpower. The method is simple, feasible, and widely applicable. At the same time, by comparing the water flow parameters simulated by the hydraulic model with those measured, the pipe sections with high leakage rates are identified. The upstream and downstream characteristics of the water flow parameters are combined to determine the water flow direction in the pipe section, thereby further tracing the source to the leaking pipe section. The method is fast, efficient, and can more accurately locate the leakage position.

[0065] It should be noted that, for the sake of simplicity, the aforementioned method embodiments are all described as a series of actions. However, those skilled in the art should understand that this application is not limited to the described order of actions, because according to this application, some steps can be performed in other orders or simultaneously.
