[0070] Step 1: Construct a real-time valve status monitoring strategy to adapt to valve status monitoring in different application scenarios; specifically including the following steps:

[0079] operation vector ;in, Indicates from valve To valve The change in valve opening. Indicates valve and valves Operation time interval; Indicates from valve Switch to valve scheduling costs;

[0080] Step 1.2: Construct an intelligent monitoring strategy based on the valve-pipeline network diagram model, including the following steps:

[0081] Constructing the scheduling objective function ; This represents the actual pressure vector of the node. Represents the target pressure vector; It represents the L2 norm, which minimizes the overall deviation between actual pressure and target pressure, emphasizing smooth adjustment.

[0082] This represents the vector of valve opening change. ,in, Indicates the number of valve scheduling operations;

[0083] Represents the flow vector between nodes; Represents the water demand vector; It represents the L1 norm, which minimizes the total deviation between flow rate and water demand, and is sensitive to outliers; These represent pressure weight, flow weight, and cost weight, respectively.

[0084] The non-dominated sorting genetic algorithm (NSGA) is used to solve the objective function and obtain the optimal solution to the objective function, namely, the optimal actual pressure vector, the optimal flow vector between nodes, the scheduling cost, and the change in opening degree.

[0085] Based on the valve opening change and valve status, the valve opening is optimized to achieve the optimal valve opening, thereby ensuring that the water delivery in the pipeline network reaches the optimal transmission state.

[0086] Step 2: Based on the water quality characteristics flowing through the target valve within the target area, optimize the target valve status acquisition strategy and valve coordination strategy; including the following steps:

[0087] Step 2.1: Obtain water quality characteristics of the target area and construct a water quality feature vector. ;in, These represent the normalized values ​​of turbidity, residual chlorine, pH, and conductivity, respectively.

[0088] Step 2.2: Using water quality feature vectors and a clustering algorithm, classify water quality into drinking water, reclaimed water, rainwater, and industrial water;

[0089] Step 2.3: Set the water quality risk index ;in, Indicates parameter weights, Indicates the pollutant weighting. Indicates the weighted sum of pollutants, Indicates the reference water quality vector;

[0095] in, These represent the maximum risk index and the minimum risk index, respectively.

[0096] Step 2.6: Optimize valve coordination strategy, including:

[0097] Construct a valve collaborative optimization model:

[0099] Constraints: ;in, ; Represents the target water quality feature vector; Indicates the difference in water quality characteristics due to mixing; This indicates the actual pressure at the node under the current water quality conditions; These represent the pressure weight, flow weight, and cost weight of the current water quality, respectively. This represents the dimension of the water quality feature vector.

[0100] The NSGA algorithm is used to solve the coordination objective function to obtain the optimal valve opening change under the current water quality. Specifically:

[0101] First, define chromosome encoding: use real number encoding, i.e. Each gene represents a change in the opening degree of a valve; the gene range is... ;

[0102] Population initialization: Randomly generate a set of aperture change vectors ;in, This represents the lower triangular Cholsky decomposition matrix; ; Represents the correction vector;

[0103] Calculate the scalar function value and constraint violation amount for each individual in the population (water quality and water pressure are known), and sort them according to non-dominance relations; within the same non-dominance relation level, calculate the crowding distance of individuals;

[0104] Parents are selected through a binary tournament process, and crossover mutation is performed to generate mutated offspring. Parents and offspring are then merged, and a non-dominated sorting comparison of crowding distance is performed. Within the same level, the individual with the largest crowding distance (change in opening degree) is selected. Then, n individuals are selected from the highest to lowest non-dominated levels to generate a new population. This process is repeated until the maximum number of iterations is reached to obtain the optimal opening degree change vector. .

[0105] like Figure 2As shown, this illustrates the optimal valve opening for different valves under varying water qualities. Reducing the valve opening lowers the valve operating cost. (e.g., time or energy consumption).

[0106] Step 3: During valve control strategy execution, based on scenario requirements and the pipeline topology of the target area, perceive the valve status under multiple water quality scenarios; including the following steps:

[0107] Constructing the topology-water quality coupled graph structure: ;in, Represents the water quality characteristic matrix. ;in, Indicates the number of water quality feature vectors;

[0108] Will The input is fed into a pre-trained convolutional network model, which outputs the scene type of the target region to identify the scene of the target region; the scene type of the target region includes: normal scheduling, emergency scheduling, and water pollution.

[0109] Based on the scene type of the target area, node sensing focus and edge sensing focus are set, and the sensing focus and acquisition frequency are dynamically adjusted, including:

[0110] In a normal scheduling scenario, the node's perception focus includes traffic and pressure; the edge's perception focus is the traffic gradient; and the basic sampling frequency can be 1Hz.

[0111] In emergency dispatch scenarios, the node sensing focus includes pressure change; the edge sensing focus is the pressure gradient; and the basic sampling frequency can be 10Hz.

[0112] In the case of water pollution, the node sensing focus includes pollutant concentration; the sensing focus changes to valve opening; and the basic sampling frequency can be 5Hz.

[0113] In the case of pipeline flushing, the node sensing focus is on the turbidity and flow rate of the water; the basic sampling frequency can be 3Hz.

[0114] After setting the node's sensing focus, the fusion state of the node is calculated and obtained based on the water quality type. ;in, Indicates the number of parameters included in the sensing focus; Indicates the parameters included in the perceived focus;

[0115] Kalman gain ;

[0116] For example, in a normal scheduling scenario, ; For traffic, For pressure;

[0117] After setting the edge-aware focus, the edge state is: ;

[0118] in, These represent the fusion state of the current node, the fusion state of the neighboring nodes, the water quality feature vector of the current node, and the water quality feature vector of the neighboring nodes, respectively.

[0119] Step 4: Based on the valve status under multiple water quality scenarios, predict the future state of the valve.

[0120] Based on water quality, construct a new node state vector. ;

[0121] New edge state vector ;in, Indicates the diffusion flux of pollutants;

[0122] A state prediction model is constructed using graph convolutional neural networks. and The input is fed into a pre-trained state prediction model, which outputs future node state vectors and edge state vectors.

[0123] State prediction models make state predictions in three stages: short-term, medium-term, and long-term. Short-term predictions, with a time step of 5 minutes, are specifically performed using an LSTM network.

[0124] Mid-term prediction, which has a prediction time step of 5-30 minutes, is specifically performed using a graph convolutional network (GCN).

[0125] Long-term prediction, i.e., prediction time step greater than 30 minutes, involves coupling a physical model into the graph convolutional network (GCN), i.e., adding a valve wear model. ;in, This indicates the initial maximum valve opening. This indicates the valve's maximum opening degree loss rate; Indicates the wear coefficient of the valve material; This represents the instantaneous wear rate, which can be calibrated experimentally. This indicates the maximum prediction time step. An increase in sediment content in the water flowing through the valve will lead to... An increase in the number of valve actuations will lead to Increased wear and tear on valves leads to reduced valve opening, decreased accuracy of valve flow control, and even valve failure.

[0126] By quantifying valve wear, not only can the probability of valve failure be predicted, but also by taking valve wear into account when executing valve control strategies, the system's perception of valve status (opening degree) becomes more accurate.

The electronic device is used to execute the aforementioned real-time status sensing method for online monitoring of water valves.
