Traditional pipe burst monitoring mainly relies on pressure gauges and flow meters inside the pipe network, which monitor through a single indicator such as pressure drop, but are easily disturbed by water load fluctuations, equipment failures, and other factors, resulting in a high false positive rate. In addition, existing monitoring methods lack the ability to distinguish between pipe bursts and leaks, making it impossible to provide accurate early warnings and timely initiate appropriate emergency measures.

[0034] Figure 2 is an exemplary flowchart of the city lifeline pipe network burst prevention based on the Internet of Things large model according to some embodiments of the present application. As shown inFigure 2 As shown, the flow 200 includes the following steps. In some embodiments, the flow 200 can be performed by an emergency regulatory management platform or a processor, and the following is taken as an example of the processor performing the flow 200.

[0035] At step 210, fluid pressure data is acquired.

[0036] The fluid pressure data refers to the water pressure of a plurality of pipe network nodes in a city water supply pipe network.

[0037] The pipe network node refers to a key node in the city water supply pipe network. For example, the key node can include a water pipe, a connection point of the water pipe, a branch point, a turning point, or a control point in the city water supply pipe network, etc.

[0038] In some embodiments, a plurality of pipe network nodes of the city water supply pipe network can be provided with fluid pressure monitoring devices, such as sensors, pressure gauges, etc. The processor can acquire the fluid pressure data based on the monitoring data of the fluid pressure monitoring devices.

[0039] At step 220, a pipe burst probability of the pipe network node is determined based on the fluid pressure data.

[0040] The pipe burst probability can measure the likelihood of the water pipe at the pipe network node bursting. For example, the higher the pipe burst probability, the greater the likelihood of the water pipe at the pipe network node bursting.

[0041] In some embodiments, the processor can determine the pipe burst probability of the pipe network node based on the fluid pressure data.

[0042] In some embodiments, for a pipe network node, the processor can determine the water pressure of the pipe network node based on the fluid pressure data, and then calculate a water pressure difference between the water pressure and a pressure threshold corresponding to the pipe network node. If the water pressure difference is positive, it can be determined that the pipe network node has a pipe burst risk. In some embodiments, the pipe burst probability is positively correlated with the water pressure difference, and the greater the water pressure difference, the greater the pipe burst probability.

[0043] If the water pressure difference is negative, it can be determined that the pipe network node has a lower pipe burst risk or no pipe burst risk, and the pipe burst probability can be set to 0.

[0044] The pressure threshold refers to a critical value for evaluating the likelihood of the water pressure of the pipe network node causing the water pipe to burst. In some embodiments, the processor can acquire the pressure threshold corresponding to each pipe network node from the memory.

[0045] In some embodiments, the pressure threshold can be set by a technician according to experience.

[0046] For more information on determining the pipe burst probability, please refer to the relevant description of Figure 3 and Figure 4 .

[0047] At step 230, the target valve and its valve opening degree are determined based on the burst probability, and the target valve is controlled to the valve opening degree.

[0048] The target valve refers to a valve used to control the water pressure of a pipe network node with a burst probability greater than 0. In some embodiments, the valve closest to the pipe network node with a burst probability greater than 0 can be determined as the target valve. In some embodiments, the target valve includes an electric valve, such as an angular stroke electric valve, a straight stroke electric valve, etc.

[0049] The valve opening degree refers to the opening degree of the valve.

[0050] In some embodiments, the processor can determine the valve opening degree of the target valve based on the burst probability. For example, the valve opening degree can be positively correlated with the burst probability, and the greater the burst probability, the greater the valve opening degree.

[0051] In some embodiments, the processor can be communicatively connected with the target valve or its controller, and control the opening and closing of the target valve to the valve opening degree through communication.

[0052] In some embodiments, in response to the burst probability exceeding the probability threshold, the processor can determine a supply pressure adjustment parameter based on the burst probability, the supply pressure adjustment parameter including a target water pump, a target supply pressure, and a target water pump speed; and adjust the water pump speed of the target water pump to the target water pump speed according to the supply pressure adjustment parameter, so as to adjust the supply pressure of the pipe network to the target supply pressure.

[0053] The probability threshold refers to a critical probability for evaluating the burst of a pipe network node. In some embodiments, the processor can obtain the probability threshold corresponding to the pipe network node from the memory.

[0054] In some embodiments, the probability threshold can be set by a technician according to experience.

[0055] The supply pressure adjustment parameter refers to a parameter used to adjust the supply pressure of the water pump. In some embodiments, the supply pressure adjustment parameter can include at least one of a target water pump, a target supply pressure, and a target water pump speed, etc.

[0056] The target water pump refers to a water pump directly connected with a pipe network node with a burst probability greater than 0. In some embodiments, the target water pump can be determined by querying the first preset table or the second preset table.

[0057] For more information about the first preset table or the second preset table, see the relevant description later.

[0058] The target supply pressure refers to the pressure supply required to reduce the burst probability of the target water pump to below the probability threshold. In some embodiments, the target supply pressure can be determined based on the burst probability by querying the first preset table or the second preset table.

[0059] The target water pump rotating speed refers to the water pump rotating speed required to reduce the pipe burst probability of the target water pump to below the probability threshold. In some embodiments, the target water pump rotating speed can be determined based on the pipe burst probability by querying the first preset table or the second preset table.

[0060] In some embodiments, the processor can determine the supply pressure adjustment parameter based on the pipe burst probability in various ways. For example, the processor can determine the supply pressure adjustment parameter based on the first preset table.

[0061] The first preset table reflects the correspondence between each pipe network node distributed in the urban water supply pipe network, the pipe burst probability corresponding to the pipe network node, and the target water pump, the target supply pressure, and the target water pump rotating speed in the supply pressure adjustment parameter. In some embodiments, the processor can determine the target water pump, the target supply pressure, and the target water pump rotating speed corresponding to the pipe network node by querying the first preset table based on the pipe network node with a pipe burst probability greater than 0.

[0062] In some embodiments, the first preset table can be set by a technician according to experience or historical data. For example, the first preset table can be constructed with the historical target supply pressure and the historical target water pump rotating speed corresponding to the target water pump of the pipe network node with good prevention effect (e.g., no burst has occurred again) in the historical data. In some embodiments, the pipe burst probability can be negatively correlated with the target supply pressure and the target water pump rotating speed. For example, the greater the pipe burst probability, the lower the target supply pressure and the lower the target water pump rotating speed.

[0063] In some embodiments, the supply pressure adjustment parameter is related to at least one of the type of the target region, the region radius, the vehicle flow of the target region, etc.

[0064] The target region refers to a region related to the pipe network node that needs to be further monitored. For more information about the target region, see the related description of Figure 3 .

[0065] The type of the target region can reflect information such as the vehicle flow and the vehicle speed of the target region. For example, the type of the target region can be a highway, a main road, an intersection, etc.

[0066] In some embodiments, the processor can obtain the urban water supply pipe network distribution map from the memory and determine the type of the target region from the urban water supply pipe network distribution map. The urban water supply pipe network distribution map is a professional drawing that shows the spatial layout and connection relationship of water sources, pipe network nodes, pump stations, and auxiliary facilities in the urban water supply pipe network. In some embodiments, the urban water supply pipe network distribution map includes position information of a plurality of pipe network nodes, road information, etc.

[0067] The region radius refers to the radius of the target region established with the monitoring center as the center. For more information about the region radius and the monitoring center, see the related description of Figure 3 .

[0068] In some embodiments, the traffic volume of the target area is related to the type of the target area.

[0069] In some embodiments, the processor can further determine the traffic volume of the target area based on the road surface image. For example, the processor can calculate the number of vehicles passing by per unit time in the road surface image to determine the traffic volume of the target area.

[0070] For more information about the road surface image, please refer to the relevant description of Figure 3 .

[0071] In some embodiments, the processor can determine the supply pressure adjustment parameter through the second preset table.

[0072] The second preset table reflects the correspondence between each pipe network node distributed in the urban pipe network, the pipe network node corresponding pipe burst probability, and the type of the target area where the pipe network node is located, the area radius, the traffic volume of the target area, and the target water pump, the target supply pressure, and the target water pump speed in the supply pressure adjustment parameter. The processor can determine the target water pump, the target supply pressure, and the target water pump speed corresponding to the pipe network node with a pipe burst probability greater than 0 by querying the second preset table based on the pipe network node with a pipe burst probability greater than 0, the pipe burst probability, the type of the target area where the pipe network node is located, the area radius, the traffic volume of the target area.

[0073] In some embodiments, the second preset table can be set by technicians according to experience or historical data. For example, the historical target supply pressure and the historical target water pump speed corresponding to the target water pump of the pipe network node with good prevention effect (e.g., no burst has occurred again) in the historical data can be used to construct the second preset table in combination with the type of the historical target area where the above-mentioned target water pump is located, the historical area radius, and the traffic volume of the historical target area.

[0074] According to some embodiments of the present application, when adjusting the target supply pressure of the target water pump corresponding to the pipe network node with a pipe burst risk, the type of the area where the pipe network node is located, the area radius, and the traffic volume of the area are considered at the same time, which can more flexibly adjust the supply pressure of the target water pump for different areas. For example, in a high-risk area (e.g., a main road, a large traffic volume area, etc.), the supply pressure of the target water pump can be reduced as soon as possible (e.g., when the pipe burst probability is at a lower value) to avoid the harm and loss caused by pipe burst, while in a low-risk area (e.g., a branch road, a small traffic volume area, etc.), the supply pressure of the target water pump can be delayed (e.g., when the pipe burst probability is at a higher value) to avoid the influence of the reduced supply pressure of the water pump on the downstream urban residents. Dynamic adjustment of the target supply pressure is achieved, the protection of the high-risk area is strengthened, and the efficient operation of the urban pipe network in the low-risk area is ensured.

[0075] In some embodiments, the processor can be communicatively connected with the target water pump or a controller thereof, and adjust the water pump rotating speed of the target water pump to a target water pump rotating speed based on the determined supply pressure adjustment parameter, so as to adjust the supply pressure of the pipe network to the target supply pressure.

[0076] According to some embodiments of the present application, by setting the supply pressure and water pump rotating speed of the target water pump to be automatically adjusted when the pipe burst probability of the pipe network node exceeds the probability threshold value, the required reduction value of the target water pump supply pressure can be accurately controlled, and the hydraulic impact risk in the pipe network caused by the sudden and large reduction of the supply pressure can be avoided. In addition, different target water pump supply pressures and water pump rotating speeds are set for different pipe network nodes and different pipe burst probabilities, which can improve the flexibility of supply pressure adjustment, and avoid excessive reduction of the supply pressure of the target water pump to affect the downstream urban residents.

[0077] According to some embodiments of the present application, by analyzing the fluid pressure data in the urban water supply pipe network, determining the pipe burst probability of each pipe network node, and determining the target valve and its valve opening degree based on the pipe burst probability, the target valve that needs to be controlled can be quickly and accurately located, and the opening degree of the target valve can be accurately controlled, so as to avoid the pipe burst of the pipe network node while reducing the impact on the urban residents.

[0078] Figure 3 is an example flowchart of generating a hedging instruction according to some embodiments of the present application. As shown in Figure 3 , the flow 300 includes the following steps. In some embodiments, the flow 300 can be executed by a processor.

[0079] Step 310, determining a target area based on the fluid pressure data.

[0080] In some embodiments, the processor can determine, as the target area, an area composed of multiple pipe network nodes whose water pressure in the fluid pressure data is greater than a pressure threshold value.

[0081] In some embodiments, the processor can determine the monitoring center and the area radius based on the fluid pressure data and the pressure threshold value, and determine the target area based on the monitoring center and the area radius.

[0082] For more information about the pressure threshold value, please refer to the related description of Figure 2 .

[0083] The monitoring center refers to the key monitoring point of the target area.

[0084] In some embodiments, for each node in the multiple pipe network nodes in the target area, the processor can determine the water pressure of the pipe network node based on the fluid pressure data, obtain the pressure threshold value corresponding to the pipe network node from the processor, and calculate the water pressure difference between the water pressure and the pressure threshold value.

[0085] In some embodiments, the processor selects, from the plurality of water pressure difference values of the plurality of pipe network nodes, a plurality of pipe network nodes with water pressure difference values greater than 0 as reference pipe network nodes. In some embodiments, the processor can construct a to-be-clustered vector with the water pressure difference value and the corresponding position coordinates of each reference pipe network node. In some embodiments, the position coordinates of the pipe network nodes can be obtained from the city water supply pipe network distribution map in the memory.

[0086] In some embodiments, the processor can cluster the plurality of to-be-clustered vectors corresponding to the plurality of reference pipe network nodes by a clustering algorithm to determine a plurality of cluster centers. The clustering algorithm can include, but is not limited to, K-Means clustering and / or density-based clustering method (DBSCAN), etc.

[0087] In some embodiments, the processor can select, from the plurality of cluster centers, a cluster center with a water pressure difference value greater than a difference threshold value as a candidate cluster center, and then sort the candidate cluster centers according to the size of the water pressure difference value, and take the position coordinates of the pipe network node corresponding to the candidate cluster center with the largest water pressure difference value as the monitoring center. The difference threshold value refers to the critical water pressure difference value for judging whether a cluster center can be a candidate cluster center.

[0088] In some embodiments, the difference threshold value can be set by the technician according to experience.

[0089] In some embodiments, the processor can determine the area radius based on the fluid pressure data of the monitoring center, for example, the area radius can be positively correlated with the water pressure difference value of the monitoring center, and the larger the water pressure difference value of the monitoring center, the larger the area radius.

[0090] In some embodiments, the processor can take the area covered by the monitoring center with the area radius as the target area.

[0091] According to some embodiments of the present application, by determining the pipe network nodes with water pressure difference values greater than 0 based on the water pressure and the pressure threshold value, constructing the clustering vector based on the water pressure difference values and the position coordinates of these pipe network nodes, determining the cluster center by the clustering algorithm, determining the monitoring center based on the cluster center, determining the area radius based on the water pressure difference value of the monitoring center, and determining the target area based on the monitoring center and the area radius, the target area can be more reasonably and accurately determined, the monitoring resources (for example, monitoring devices) in the target area can be more reasonably used, and the monitoring effect can be improved, for example, more comprehensive and accurate road surface images can be obtained.

[0092] For more information about fluid pressure data, please refer to the relevant description in Figure 2 .

[0093] Step 320, determining the corresponding target monitoring device and shooting parameter based on the target area.

[0094] The target monitoring device refers to the monitoring device in the target area. In some embodiments, the target monitoring device can include a camera, a video recorder, etc. In some embodiments, the processor can take the monitoring device located in the target area as the target monitoring device.

[0095] The shooting parameter refers to the parameter involved in the monitoring by the monitoring device. In some embodiments, the shooting parameter includes at least one of the target shooting angle and the target focal length, etc.

[0096] The target shooting angle refers to the shooting angle of the target monitoring device when shooting the target area. In some embodiments, the processor can determine the target shooting angle based on the initial shooting angle and the deflection angle, wherein the initial shooting angle is the preset shooting angle of the target monitoring device, and the deflection angle refers to the angle by which the target monitoring device needs to be deflected from the initial shooting angle to shoot the target area. In some embodiments, the processor can determine a virtual connecting line based on the position coordinates of the monitoring center and the position coordinates of the target monitoring device, and then determine a virtual straight line based on the lens orientation of the target monitoring device at the initial shooting angle, and determine the deflection angle as the angle between the virtual connecting line and the virtual straight line. In some embodiments, the processor can obtain the position coordinates of the target monitoring device from the memory, for example, the city monitoring device distribution map in the memory, which contains the type, distribution position, etc. of the monitoring device.

[0097] The target focal length refers to the focal length used by the target monitoring device when shooting the target area. In some embodiments, the processor can determine the target focal length based on the shooting distance between the target monitoring device and the monitoring center of the target area. In some embodiments, the target focal length is positively correlated with the shooting distance, for example, the farther the shooting distance, the longer the target focal length.

[0098] In some embodiments, the processor can use optical ranging technology to determine the shooting distance between the target monitoring device and the monitoring center of the target area based on the monitoring image of the target area, for example, phase ranging method, similar triangle, etc.

[0100] The road surface image refers to the monitoring image of the road surface in the target area.

[0101] In some embodiments, the processor can control the lens of the target monitoring device to deflect by a deflection angle based on the target shooting angle and the initial shooting angle, so that the target monitoring device shoots the target area at the target shooting angle.

[0102] In some embodiments, the processor can control the target monitoring device to shoot the target area at the target focal length.

[0103] In some embodiments, the processor can perform image fusion on a plurality of monitoring images obtained by a plurality of target monitoring devices in the target area, to form a road surface image covering the target area. In some embodiments, the image fusion method can include but is not limited to Alpha fusion, Poisson fusion, etc.

[0105] The road surface water seepage feature refers to the relevant features of the road surface water seepage in the target area. For example, water seepage position, water seepage flow, etc.

[0106] In some embodiments, the processor can determine the water seepage feature through image recognition technology. The image recognition technology includes but is not limited to Scale-invariant feature transform (SIFT) algorithm, deep learning technology, image segmentation technology, etc.

[0108] The water seepage flow refers to the water output of the water seepage point per unit time. In some embodiments, the processor can obtain images continuously shot by the target monitoring device per unit time, and determine the water seepage flow through image recognition technology based on the continuously shot images.

[0109] In step 350, a pipe burst probability of a pipe network node of the target area is determined based on the road surface water seepage feature and the fluid pressure data.

[0110] In some embodiments, the processor can determine the pipe network node corresponding to the water seepage position based on the water seepage position, and determine the water pressure of the pipe network node corresponding to the water seepage position based on the fluid pressure data, and then determine the water pressure difference value of the pipe network node corresponding to the water seepage position based on the water pressure.

[0111] For more information about the water pressure difference value, please refer to the related description of Figure 2 .

[0112] In some embodiments, the processor can normalize the water seepage flow and the water pressure difference value, and then perform weighted summation on the normalized water seepage flow and the water pressure difference value to obtain a pipe burst probability score.

[0113] The burst probability score can be obtained based on the following formula (1) for example:

[0114] (1)

[0115] In formula (1), represents the burst probability score, represents the normalized water seepage flow, represents the normalized water pressure difference, and is a coefficient greater than 0, and the coefficient and can be preset based on prior experience.

[0116] In some embodiments, the burst probability is positively correlated with the burst probability score, and the higher the burst probability score, the higher the burst probability.

[0117] At step 360, in response to the burst probability exceeding the probability threshold, a risk avoidance instruction is generated, and the risk avoidance instruction is broadcast to vehicles in the target area.

[0118] More details about the probability threshold can be found in the description of Figure 2 .

[0119] The risk avoidance instruction refers to a safety control instruction indicating that vehicles, pedestrians, etc. avoid danger. In some embodiments, the risk avoidance instruction includes a risk avoidance position.

[0120] The risk avoidance position refers to a position that needs to be avoided. In some embodiments, the processor can take the water seepage position as the risk avoidance position.

[0121] In some embodiments, the risk avoidance instruction further includes a broadcast intensity, and the broadcast intensity is related to the type of the target area and / or the type of the vehicle.

[0122] The broadcast intensity reflects the degree of urgency of the execution of the risk avoidance instruction. In some embodiments, the broadcast intensity includes at least one of the frequency, the duration, etc. of the broadcast.

[0123] In some embodiments, the processor can broadcast the risk avoidance instruction in various ways. For example, the risk avoidance instruction is broadcast through a voice broadcast device in the target monitoring device. For another example, the broadcast is performed through a drone in the airspace above the target area. For another example, the broadcast is performed through a vehicle-mounted radio device (e.g., a vehicle-mounted radio).

[0124] The vehicle types include common vehicles and special vehicles. The special vehicles refer to vehicles with special properties. The special vehicles include, but are not limited to, buses, school buses, dangerous goods transport vehicles, etc. The common vehicles refer to vehicles other than the special vehicles. In some embodiments, the processor can acquire traffic data images in a range based on the monitoring devices in the target area and the surrounding area (e.g., within 2 kilometers outside the target area), and identify the vehicle types of all vehicles in the traffic data images through image recognition technology.

[0125] For more information about the type of the target area, see the related description of Figure 2 .

[0126] In some embodiments, the processor can determine the broadcast strength in multiple ways. For example, the processor can determine the broadcast strength based on a third preset table.

[0127] The third preset table reflects the corresponding relationship between the type of the target area, the presence of special vehicles, and the broadcast play frequency and duration. In some embodiments, the processor can determine the broadcast play frequency and duration by querying the third preset table based on the type of the target area and the presence of special vehicles in the target area and the surrounding area. For example, if the type of the target area is a highway or a main road, the processor can reduce the broadcast play frequency and duration to avoid distracting the driver's attention. For another example, if there are special vehicles in the target area and the surrounding area, the broadcast play frequency can be increased to alert the drivers of the special vehicles as much as possible.

[0128] In some embodiments, the third preset table can be set by technicians according to experience.

[0129] According to some embodiments of the present application, the broadcast strength (such as the play frequency and the play duration) of the safety warning instruction can be dynamically adjusted according to the type of the target area and the type of the vehicles in the target area and the surrounding area, so as to reduce the interference on the driver's attention while ensuring the safety alert effect, and to achieve precise warning for special target areas or special vehicles.

[0130] According to some embodiments of the present application, by combining the fluid pressure data and the road surface water seepage characteristics to analyze the pipe burst probability of the pipe network node, the high-risk area (i.e., the target area) can be dynamically determined, and the accuracy of judging the pipe burst probability can be improved; at the same time, the vehicles in the target area and the surrounding area can be broadcast in real time in combination with the risk avoidance instruction, so as to form a closed loop of "monitoring-analysis-warning-avoidance". Compared with the time lag of monitoring and warning caused by the traditional artificial inspection, some embodiments of the present application can improve the efficiency of monitoring and warning of the pipe burst probability of the pipe network, and also improve the safety of vehicles or personnel property. In addition, actively prompting the vehicles in the high-risk area to detour or brake can reduce the traffic accidents or economic losses caused by the pipe burst, and realize the technical upgrade from passive response to active avoidance of the safety protection of the urban water supply pipe network.

[0131] It should be noted that the above description of the process 300 is merely for example and illustration, and does not limit the scope of application of the present application. Various modifications and changes can be made to the process 300 by those skilled in the art under the guidance of the present application. However, these modifications and changes are still within the scope of the present application. For example, the processor can dynamically adjust the shooting parameters based on the target area, in combination with the location, lighting conditions, etc. of the target area.

[0132] Figure 4 is an exemplary flowchart of determining the pipe burst probability according to some embodiments of the present application.

[0133] In some embodiments, the emergency supervision and management platform is further configured to: construct a pipe burst prediction graph 430 based on the road surface water seepage characteristics 410 and the fluid pressure data 420; determine a first pipe burst probability 450 of the pipe network node by a first prediction model 440 based on the pipe burst prediction graph 430; the first prediction model is a machine learning model; determine a second pipe burst probability 480 of the pipe network node by a second prediction model 470 based on the fluid pressure data 460 of the preset historical period; and determine the pipe burst probability 490 of the pipe network node by weighted fusion based on the first pipe burst probability 450 and the second pipe burst probability 480.

[0134] The pipe burst prediction graph refers to a knowledge graph representing the potential risk distribution of pipe burst of each node of the pipe network.

[0135] In some embodiments, the emergency supervision and management platform can construct a pipe burst prediction graph based on the road surface water seepage characteristics and the fluid pressure data. For more details about the road surface water seepage characteristics and the fluid pressure, see Figure 2 and the related description thereof.

[0136] In some embodiments, the pipe burst prediction graph can be composed of at least one node and at least one edge, and the node has a corresponding node feature.

[0137] In some embodiments, the node includes a pipe network node, a water seepage node. More about the pipe network node, see step 210 and its related description. The water seepage node corresponds to the water seepage position in the road surface water seepage feature.

[0138] In some embodiments, the node features of the pipe network node can include the fluid pressure data corresponding to the node and the water pipe material. The node features of the water seepage node can include the road surface water seepage feature.

[0139] In some embodiments, the water pipe material can be obtained by querying the material list in the construction drawings or the completion acceptance report of the city underground pipe network.

[0140] In some embodiments, the edges of the pipe burst prediction graph include first type edges and second type edges. The first type edges are used to connect the pipe network nodes. In some embodiments, if there is a physical connection relationship between the pipe network nodes, there is a first type edge between them. Wherein, the physical connection relationship refers to the topological association that the pipe network nodes are directly connected in physics or connected through pipe auxiliary equipment (such as valves, tees, flanges, etc.) and form a continuous water flow path. The edge features of the first type edge include the pressure difference between the two pipe network nodes. The second type edges are used to connect the pipe network nodes and the water seepage nodes. In some embodiments, if the physical distance between the water seepage node and the pipe network node is less than the distance threshold, there is a second type edge between them, wherein the distance threshold can be set by the person skilled in the art according to experience. The edge features of the second type edge include the physical distance.

[0141] The first pipe burst probability is a parameter representing the pipe burst possibility obtained by fusing the spatial structure of the pipe network.

[0142] In some embodiments, the emergency management platform can determine the first pipe burst probability of the pipe network node based on the pipe burst prediction graph through a first prediction model.

[0143] The first prediction model refers to a model used to predict the first pipe burst probability of the pipe network node. In some embodiments, the first prediction model is a machine learning model. For example, the first prediction model can include one or more combinations of a deep neural network (DNN) model or a convolutional neural network (CNN) model or other custom models.

[0144] In some embodiments, the input of the first prediction model can be the pipe burst prediction graph, and the output of the first prediction model can be the first pipe burst probability of the pipe network node.

[0145] In some embodiments, the first prediction model can be trained by a plurality of first training samples with first labels to obtain an initial first prediction model. The first training samples can include a burst pipe prediction graph corresponding to a first historical time point. The first labels can include a condition of whether a pipe network node actually bursts in a time period from the first historical time point to a second historical time point under the first training sample. The first historical time point is prior to the second historical time point. In some embodiments, for a pipe network node that bursts in the time period from the first historical time point to the second historical time point, the longer the time interval from the first historical time point to the burst time of the pipe network node, the lower the value of the first burst pipe probability of the pipe network node. For a pipe network node that does not burst, the first burst pipe probability is zero.

[0146] In some embodiments, the first training samples and the first labels can be obtained based on historical data.

[0147] In some embodiments, the emergency supervision and management platform can input a plurality of first training samples with first labels into the initial first prediction model, construct a loss function based on the first labels and the results of the initial first prediction model, and update the parameters of the initial first prediction model by gradient descent or other methods based on the loss function. When a preset condition is met, the model training is completed, and a trained first prediction model is obtained. The preset condition can be that the loss function converges, the number of iterations reaches a threshold, etc.

[0148] The second burst pipe probability is a parameter representing the possibility of burst pipe obtained by fusing the time series prediction of the pipe network.

[0149] In some embodiments, the emergency supervision and management platform can determine the second burst pipe probability of the pipe network node based on the fluid pressure data of a preset historical time period by the second prediction model.

[0150] The preset historical time period refers to a time interval with a pre-set time range. In some embodiments, the preset historical time period can be a period of time before the current time. In some embodiments, the preset historical time period can be set by the experience of a person skilled in the art.

[0151] In some embodiments, the length of the preset historical time period is related to the road surface water seepage feature and the water seepage threshold.

[0152] The water seepage threshold refers to a parameter for determining whether the water seepage flow is normal. In some embodiments, the water seepage threshold can be set by the experience of a person skilled in the art.

[0153] In some embodiments, the greater the difference between the water seepage flow in the road surface water seepage feature and the water seepage threshold, the shorter the length of the preset historical time period.

[0154] In some embodiments of the present application, the time length of the preset historical period is related to the pavement water seepage feature and the water seepage threshold. When the difference between the pavement water seepage feature and the water seepage threshold increases, it indicates that the degree of pavement water seepage is aggravated, and the risk of pipe burst is significantly increased. At this time, the time length of the preset historical period can be shortened accordingly, so as to improve the calculation efficiency, speed up the system response speed, and realize more timely early warning and disposal.

[0155] The second prediction model refers to a model for predicting the second pipe burst probability of the pipe network node. In some embodiments, the second prediction model is a machine learning model. For example, the second prediction model can include one or more combinations of a Deep Neural Network (DNN) model or a Convolutional Neural Network (CNN) model or other custom models.

[0156] In some embodiments, the input of the second prediction model can be the fluid pressure data of the pipe network node in the preset historical period, and the output of the second prediction model can be the second pipe burst probability of the pipe network node.

[0157] In some embodiments, the second prediction model can be obtained by training an initial second prediction model through a plurality of sets of second training samples with second labels. The second training sample can include the fluid pressure data of the sample pipe network node in a first preset time period in the historical data. The second label can include the actual pipe burst situation of the sample pipe network node in a second preset time period after the first preset time period. If a pipe burst occurs, the second label takes a value of 1, and if not, it takes a value of 0. The length of the first preset time period is the same as the length of the preset historical period, and the second preset time period can be set by a person skilled in the art according to experience.

[0158] In some embodiments, the second training sample and the second label can be obtained based on the historical data.

[0159] The training process of the second prediction model is similar to that of the first prediction model, and the specific training process is described above.

[0160] In some embodiments, the emergency supervision and management platform can perform weighted fusion based on the first pipe burst probability and the second pipe burst probability of the pipe network node to determine the pipe burst probability of the pipe network node. For more details about the pipe burst probability, see step 220 and its related description.

[0161] In some embodiments, the weighted fusion can be calculated by formula (2), and formula (2) is as follows:

[0162] (2)

[0163] In formula (2), a pipe burst probability of a pipe network node; a first pipe burst probability of a pipe network node; a weight of the first pipe burst probability; a second pipe burst probability of a pipe network node; a weight of the second pipe burst probability; and satisfies .

[0164] In some embodiments, the weight of the second pipe burst probability in the weighted fusion is related to the area radius. For more information about the area radius, see step 310 and its related description.

[0165] In some embodiments, the greater the area radius, the greater the weight of the second pipe burst probability.

[0166] In some embodiments of the present application, the weight of the second pipe burst probability is related to the area radius. As the area radius increases, the load of the monitoring device can increase accordingly; and in view of the non-uniformity of its spatial distribution, the identification effectiveness of the road surface water seepage feature can decrease accordingly. Therefore, increasing the weight of the second pipe burst probability based on the fusion time series prediction helps to improve the reliability of the pipe burst probability prediction.

[0167] In some embodiments of the present application, by constructing a pipe burst prediction atlas and fusing fluid pressure data, the first prediction model models and analyzes the pipe network structure from the spatial dimension, and outputs the first pipe burst probability representing the spatial risk distribution; at the same time, based on the fluid pressure time series data of a preset historical period, the second prediction model captures the pressure dynamic evolution law from the time dimension, and outputs the second pipe burst probability representing the time dimension. Finally, the system generates the comprehensive pipe burst probability of the pipe network node by weighted fusion of the prediction results of the above-mentioned time and space dual dimensions (i.e. the first pipe burst probability and the second pipe burst probability). This spatio-temporal coupling prediction method effectively overcomes the limitations of traditional single-dimensional (only spatial or only temporal) evaluation models, and comprehensively utilizes the pipe network topological structure information and historical pressure change characteristics, significantly improving the accuracy and reliability of the pipe burst probability prediction.
