[0047] An embodiment of the present invention provides a leakage protection method and system for water-related areas, which is used to solve the technical problem that the existing technology mainly performs leakage protection on the water-related areas by adding a leakage protector to the power supply equipment in the water-related areas, but the setting value of the action current of the leakage protector is not related to the electric shock current of the biological body, but uses the effective value of the residual current as the only action criterion, which easily leads to the occurrence of false operation or refusal to operate, thereby reducing the reliability of the operation of electrical equipment in the water-related areas.

[0048] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0049] See also Figure 1 , Figure 1 This is a flowchart of the steps of a leakage protection method for water-related areas provided in Example 1 of the present invention.

[0050] The present invention provides a leakage protection method for water-related areas, comprising:

[0051] Step 101: Obtain residual current signals on both sides of the water-wading area to be monitored, perform signal preprocessing on each residual current signal, and obtain two target current waveforms;

[0052] In an embodiment of the present invention, residual current signals on both sides of the water-wading area to be monitored are obtained by setting residual current transformers on both sides of the water-wading area to be monitored, and signal preprocessing is performed on each residual current signal to obtain two target current waveforms.

[0053] Step 102: Perform waveform matching on the two target current waveforms to obtain a current similarity value;

[0054] In an embodiment of the present invention, the Fréchet distance algorithm is used to calculate the similarity between two target current waveforms to obtain a current similarity value.

[0055] Step 103: When the current similarity value is greater than a preset similarity threshold, a pre-trained electric shock detection model is used to perform electric shock detection on the two target current waveforms to obtain the electric shock type corresponding to the water-worn area to be monitored;

[0056] In an embodiment of the present invention, it is determined whether the current similarity value is greater than a preset similarity threshold. If the current similarity value is greater than the similarity threshold, a pre-trained electric shock detection model is used to perform electric shock detection on the two target current waveforms to obtain the electric shock type corresponding to the water-worn area to be monitored. If the current similarity value is less than or equal to the similarity threshold, the process jumps to step 101.

[0057] It should be noted that when a fault leakage occurs in the water-wading area, the target current waveforms on both sides of the water-wading area no longer overlap, and the similarity between the two target current waveforms decreases as the fault leakage in the water-wading area increases.

[0058] Step 104: Adjust the power supply circuit on the water-related area to be monitored according to the type of electric shock.

[0059] In this embodiment of the present invention, the type of electric shock is determined to be biological. If the electric shock type is biological, the power supply circuit in the water-related area is disconnected and an alarm is broadcasted for the power supply circuit. If the electric shock type is not biological, it indicates a non-biological leakage fault, and an alarm is broadcasted for the power supply circuit in the water-related area.

[0060] In an embodiment of the present invention, two target current waveforms are matched to obtain a current similarity value. When the current similarity value exceeds a preset similarity threshold, a pre-trained electric shock detection model is used to detect electric shocks on the two target current waveforms. The electric shock type corresponding to the monitored water-related area is determined, and the power supply circuit associated with the monitored water-related area is adjusted based on the electric shock type. This overcomes the technical problem that existing leakage protectors use the effective value of the residual current as the sole action criterion, which can easily lead to false operation or refusal to operate, thereby reducing the reliability of electrical equipment in water-related areas. Compared with traditional leakage protectors, the present invention uses a pre-trained electric shock detection model to detect electric shocks on the two target current waveforms when the current similarity value exceeds a preset similarity threshold. The corresponding electric shock type is then determined, and the power supply circuit associated with the monitored water-related area is adjusted based on the electric shock type, thereby reducing the false alarm rate of leakage monitoring in water-related areas. At the same time, the power supply circuit is adjusted based on the electric shock type, reducing the risk of electric shock to personnel and improving the reliability of electrical equipment in water-related areas.

[0061] See also Figure 2 , Figure 2 This is a flowchart of the steps of a leakage protection method for water-related areas provided in the second embodiment of the present invention.

[0062] The present invention provides a leakage protection method for water-related areas, comprising:

[0063] Step 201: Obtain residual current signals on both sides of the water-wading area to be monitored, perform signal preprocessing on each residual current signal, and obtain two target current waveforms;

[0064] It should be noted that, when the residual current signals on both sides of the water-wading area to be monitored are not obtained, the process jumps to step 201 , thereby performing real-time monitoring of the water-wading area to be monitored.

[0065] Furthermore, step 201 includes the following sub-steps:

[0066] S11, using a moving average filtering method to filter each residual current signal to obtain two filtered current signals;

[0067] In the embodiment of the present invention, a moving average filtering method is used to smooth each residual current signal to obtain two filtered current signals.

[0068] It should be noted that the moving average filter method is used to smooth time series data, remove noise and random fluctuations, while retaining the main trend of the signal. It achieves the filtering effect by calculating the average value of the data points within a certain window. The specific processing process of the moving average filter method is as follows: A1. Given a signal sequence containing N samples, where n is the index of the sample (from 0 to N-1). A2. The moving average filter performs filtering by sliding a window of fixed length M across the signal sequence and calculating the average value of the samples within the window. For each position k in the sliding window, the filtered output y[k] is expressed as:

[0069]

[0070] in, is the smoothed data value (i.e. the moving average at the kth moment), is the measurement value at time k in the original data sequence, is the measurement value at time k-1 in the original data sequence, is the measurement value at time k-2 in the original data sequence, is the measurement value at time k-M+1 in the original data sequence.

[0071] S12, normalizing each filtered current signal to obtain two target current signals;

[0072] In the embodiment of the present invention, normalization operations are performed on each filtered current signal to obtain two target current signals.

[0073] S13. Perform waveform conversion processing on each target current signal to obtain two target current waveforms.

[0074] In an embodiment of the present invention, a drawing tool (such as Matplotlib) is used to combine each target current signal with a time axis to obtain two target current waveforms.

[0075] Step 202: Parameterize each target current waveform to obtain two current point sequences;

[0076] In the embodiment of the present invention, the two target current waveforms are converted into current time series data respectively. That is, P (P is the current time series data of the first target current waveform) and Q (Q is the current time series data of the second target current waveform), P={p1,p2,…,p m}, Q={q1,q2,…,q n The time and current value (t, I) of each point in P and Q.

[0077] Step 203: Calculate the similarity between the two current point sequences using the Frechet distance method to obtain a current similarity value.

[0078] In an embodiment of the present invention, two current point sequences are input into a preset Frechet distance function to obtain a current similarity value.

[0079] It should be noted that the Frechet distance function is specifically:

[0080]

[0081]

[0082] in, To obtain the infimum (i.e., find the parameterization that minimizes the maximum distance among all possible parameters), To consider all points at time t under given parameters and The maximum value of the distance between is the parameterization at time t and The distance between corresponding points on the lower curve, P and Q, =(α(t) / β(t)) represents the parameterization of the two curves. Each function α(t) and β(t) maps time t to a point on the curve, where both α and β must start at 0 and end at 1 to ensure that the curves go from the starting point to the end point.

[0083] Step 204: When the current similarity value is greater than a preset similarity threshold, a pre-trained electric shock detection model is used to perform electric shock detection on the two target current waveforms to obtain the electric shock type corresponding to the water-worn area to be monitored;

[0084] Furthermore, the electric shock detection model includes a backbone network and a detection network, and step 204 includes the following sub-steps:

[0085] S21, extracting time domain features of two target current waveforms to obtain first current feature data;

[0086] In an embodiment of the present invention, time domain feature extraction is performed on two target current waveforms to obtain first current feature data, wherein the first current feature data includes but is not limited to the mean, variance, peak value, kurtosis and skewness of the target current waveforms.

[0087] S22, extracting frequency domain features of the two target current waveforms to obtain second current feature data;

[0088] In an embodiment of the present invention, second current characteristic data of two target current waveforms are extracted by Fourier transform, wherein the second current characteristic data includes but is not limited to main frequency, harmonic components, etc.

[0089] S23, extracting features of the two target current waveforms through the backbone network to obtain third current feature data;

[0090] In an embodiment of the present invention, feature extraction is performed on two target current waveforms through a backbone network to obtain third current feature data, wherein the backbone network includes but is not limited to a pre-trained convolutional neural network (CNN) or a long short-term memory network (LSTM).

[0091] S24. Perform electric shock detection on the first current characteristic data, the second current characteristic data, and the third current characteristic data through a detection network to obtain an electric shock type corresponding to the water-wading area to be monitored.

[0092] In an embodiment of the present invention, electric shock detection is performed on the first current characteristic data, the second current characteristic data and the third current characteristic data through a detection network to obtain the type of electric shock corresponding to the water-related area to be monitored, wherein the detection network includes but is not limited to a pre-trained SVM support vector machine.

[0093] Step 205: Adjust the power supply circuit on the water-related area to be monitored according to the type of electric shock.

[0094] Furthermore, step 205 includes the following sub-steps:

[0095] S31. When the electric shock type is non-biological electric shock, a warning is broadcast to the power supply circuit in the monitored water-related area;

[0096] In an embodiment of the present invention, when the type of electric shock is non-biological electric shock, an audible and visual alarm is used to broadcast an early warning to the power supply circuit in the monitored water-related area.

[0097] S32. When the electric shock type is biological electric shock, the circuit breaker of the power supply circuit is disconnected, and an early warning is broadcast for the power supply circuit.

[0098] In an embodiment of the present invention, when the type of electric shock is biological electric shock, the circuit breaker of the power supply circuit is disconnected, and an audible and visual alarm is used to broadcast an early warning to the power supply circuit.

[0099] Furthermore, it also includes:

[0100] When the current similarity value is less than or equal to the similarity threshold, the process jumps to executing the step of obtaining residual current signals on both sides of the water-wading area to be monitored.

[0101] It is worth mentioning that the method of steps 201 to 205 can be performed by an electric shock protection device to achieve leakage protection in water-related areas. Figure 3 As shown, the electric shock protection device includes two residual current transformers, two signal amplification circuits, two AC-DC conversion modules, two sub-controllers, a main controller, a circuit breaker, an LED module, and an audible alarm module. The electric shock protection device works as follows: B1. The residual current signal of the water-related area to be monitored is simultaneously detected by the two residual current transformers at a certain frequency (wherein the two residual current transformers are set on both sides of the water-related area to be monitored). B2. Figure 6 As shown, the residual current signal is amplified by the signal amplification circuit (i.e., the small magnification amplification module). Figure 5 As shown, the residual current signals after amplification on both sides are input into the AC-DC conversion module to obtain the residual current signal that can be identified and detected by the main controller and the sub-controller. B4. The sub-controller performs a moving average filter on the residual current signal to obtain the target current signal. B5. The main controller executes the method of steps 202 to 204. B6. See Figure 7 As shown in Figure 1, when the electric shock type is non-biological electric shock, the main controller controls the sound alarm module to broadcast an early warning to the power supply circuit on the monitored water-crossing area. B7. When the electric shock type is biological electric shock, the main controller controls the circuit breaker to disconnect and controls the sound alarm module to broadcast an early warning to the power supply circuit on the monitored water-crossing area. B8. Figure 4 When the current similarity value is less than or equal to the similarity threshold, the main controller controls the LED module to turn on and jumps to execute B1.

[0102] In an embodiment of the present invention, two target current waveforms are matched to obtain a current similarity value. When the current similarity value exceeds a preset similarity threshold, a pre-trained electric shock detection model is used to detect electric shocks on the two target current waveforms. The electric shock type corresponding to the monitored water-related area is determined, and the power supply circuit associated with the monitored water-related area is adjusted based on the electric shock type. This overcomes the technical problem that existing leakage protectors use the effective value of the residual current as the sole action criterion, which can easily lead to false operation or refusal to operate, thereby reducing the reliability of electrical equipment in water-related areas. Compared with traditional leakage protectors, the present invention uses a pre-trained electric shock detection model to detect electric shocks on the two target current waveforms when the current similarity value exceeds a preset similarity threshold. The corresponding electric shock type is then determined, and the power supply circuit associated with the monitored water-related area is adjusted based on the electric shock type, thereby reducing the false alarm rate of leakage monitoring in water-related areas. At the same time, the power supply circuit is adjusted based on the electric shock type, reducing the risk of electric shock to personnel and improving the reliability of electrical equipment in water-related areas.
