[0027] In order to enable ordinary persons in the art to better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. The same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.
[0028] Figure 1 FIG. 1 is a flow chart of a method for identifying risks of an integrated pipe gallery based on sound signal visualization according to an embodiment of the present application. Figure 1 As shown, the method includes:
[0029] S101, collecting sound signals corresponding to various types of disasters inside the utility corridor as sample sound signals, wherein the sample sound signals are stored in a utility corridor sound information disaster database.
[0030] In practice, the underground pipelines in the comprehensive pipeline corridor can undertake multiple functions such as urban information transmission, energy transportation, flood drainage and disaster reduction, waste disposal, etc. Therefore, in the daily operation of underground pipelines, pipelines with different functions are likely to suffer different types of disasters.
[0031] For example, underground pipelines that are responsible for energy transmission may have different disasters depending on the energy they transmit. Cables responsible for transmitting electric energy resources may have cable discharge disasters, and pipelines responsible for transmitting gas energy may have gas leakage disasters, etc.
[0032] Furthermore, different types of disasters produce different sound signals during their occurrence. Therefore, the identification and early warning of possible disasters in the integrated utility tunnel can be achieved based on the characteristics of different sound signals.
[0033] Optionally, based on the sound collection equipment arranged in the integrated pipe corridor, sound signals corresponding to various types of disasters occurring in the integrated pipe corridor can be collected and determined as sample sound signals.
[0034] Furthermore, a comprehensive pipeline corridor sound information disaster database can be constructed, and the collected sound signals corresponding to various disasters that may occur inside the comprehensive pipeline corridor can be stored in the constructed comprehensive pipeline corridor sound information disaster database to facilitate subsequent calling and updating of sample sound signals.
[0035] S102, performing image processing on the sample sound signal to generate a sound spectrogram of the sample sound signal, and using the sound spectrogram as a sample image of the sample sound signal, and annotating the sample image with a detection frame based on the disaster information corresponding to the sample sound signal.
[0036] In the implementation, due to the propagation characteristics of the sound signal, it is difficult to obtain the characteristics of the sound signal. Therefore, the sound signal can be processed into an image and then converted into an image that can present the characteristics of the sound signal, so that the characteristics of the sound signal can be more accurately extracted and identified based on the image.
[0037] Optionally, the sample sound signal can be converted into a corresponding sound spectrogram, wherein the sound spectrogram can present the form and characteristics corresponding to the sample sound signal. The sound signals corresponding to different types of disasters have different forms and characteristics presented in the sound spectrogram. Therefore, the features of the sound signals corresponding to different types of disasters can be extracted according to the forms and characteristics of the sound signals in the sound spectrogram.
[0038] It should be noted that, in addition to the sound spectrogram, the method of visualizing the sound signal may include other processing methods that can present the characteristics of the sound signal, which is not limited here.
[0039] Among them, the horizontal axis of the sound spectrogram represents time, the vertical axis represents frequency, and the color of the coordinate point represents energy.
[0040] Furthermore, the sound spectrogram can be used as a sample image corresponding to the sample sound signal, and based on the analysis of the expression forms and characteristics of different types of sound signals in the sound spectrogram, the forms and characteristics of different types of sound signals in the sample image can be obtained.
[0041] Based on the manifestation forms and characteristics of different types of sound signals in the sound spectrogram, the target forms and target characteristics of sample sound signals corresponding to different types of disasters in the sample images are determined and annotated.
[0042] Among them, the target forms corresponding to the sample sound signals of different types of disasters can be marked in the sample image through a rectangular detection frame, so as to generate a sample image with the detection frame marked.
[0043] Optionally, the sample image can be annotated with a detection frame through a set software, for example, through a visual image calibration tool (LabelImg software), the target shape corresponding to the fire in the sample image is marked with the label fire, the target shape corresponding to the gas leakage is marked with the label leakage, and the target shape corresponding to the cable discharge is marked with the label discharge.
[0044] S103, based on the sample image and the corresponding annotated detection frame, the disaster recognition model constructed based on the deep learning target detection algorithm is trained to generate a trained target disaster recognition model.
[0045] In implementation, the disaster identification model can be used to identify and warn of different types of disasters that may occur in the integrated pipeline corridor.
[0046] Furthermore, in order to make the disaster identification model more efficient and accurate in actual application, it is necessary to train the disaster identification model based on the deep learning target detection algorithm so that the performance of the disaster identification model based on the deep learning target detection algorithm can be optimized.
[0047] In an embodiment of the present application, the constructed disaster identification model can be trained through labeled sample images. Through multiple rounds of training, the disaster identification model based on the deep learning target detection algorithm can realize the identification of different types of disasters existing in the integrated pipeline corridor, and then generate a trained target disaster identification model.
[0048] Optionally, the loss function of the disaster identification model can be obtained based on the relevant information of the predicted detection box in the output results of the disaster identification model and the relevant information of the labeled detection box in the sample image after each round of model training. Based on the loss function, the parameters of the constructed disaster identification model can be adjusted to optimize the disaster identification model.
[0049] Furthermore, after each round of training of the disaster identification model is completed, it can be determined whether the disaster identification model of the current round meets the end condition of the model training. If the end condition of the model training is met, the model training is terminated and the target disaster identification model is generated. If the end condition of the model training is not met, the weight parameters of the disaster identification model are adjusted based on the loss results of the current round of training until the end condition of the training is met.
[0050] Among them, the corresponding model training end condition can be set based on the model accuracy of the disaster identification model, and the corresponding model training end condition can also be set based on the training rounds of the disaster identification model.
[0051] It should be noted that during the training of the disaster identification model, the model parameters of the disaster identification model can be adjusted as a whole after the set round of iterations. For example, the input resolution and batch size can be changed every 10 rounds to improve the training efficiency.
[0052] Furthermore, an optimal weight configuration of the target disaster identification model is generated.
[0053] S104, collecting the sound sequence to be identified in the integrated pipe gallery, where the sound sequence includes multiple sound signals to be identified.
[0054] Furthermore, the trained target disaster recognition model can be applied in actual scenarios, and the sound signals of the integrated pipeline corridor in the actual scenario can be collected to generate a sound sequence to be identified.
[0055] Among them, the collected sound sequence includes multiple sound signals to be identified in the integrated pipeline corridor.
[0056] S105, generating a sound spectrogram to be identified corresponding to the sound sequence to be identified, and inputting the sound spectrogram to be identified into a target disaster identification model to output a disaster identification result corresponding to the sound sequence to be identified.
[0057] In an embodiment of the present application, in order to realize the recognition of multiple disaster sound signals in the current sound sequence to be recognized based on the trained target disaster recognition model, optionally, a sound spectrogram corresponding to the sequence can be generated based on the current sound sequence to be recognized and determined as the sound spectrogram to be recognized.
[0058] Furthermore, the sound spectrogram to be identified is input into the trained target disaster identification model, the target forms of different disaster types in the sound spectrogram to be identified are identified by the model, and the detection result image is output to generate the target disaster identification result.
[0059] Among them, the risk levels of different types of disasters can also be divided based on the target disaster model identification results, so that the output results of the target disaster identification model are more intuitive. Among them, the disaster risk level can be divided into numerical levels, and the higher the corresponding numerical level, the greater the risk.
[0060] The present application proposes a method for identifying risks in an integrated pipe corridor based on the visualization of sound signals. The sound signals corresponding to various types of disasters that may exist in the integrated pipe corridor collected are used as sample sound signals, and a sound spectrogram corresponding to the sample sound signals is generated. The sound spectrogram is used as a sample image corresponding to the sample sound signal, and the target morphology corresponding to the sound signals of different types of disasters in the sample image is marked with a detection frame. According to the sample image and the detection frame marked therein, the disaster identification model constructed based on the deep learning target detection algorithm is trained to generate a target disaster identification model. Further, a sound spectrogram of the sound signal sequence to be identified collected by the integrated pipe corridor is generated, and it is input into the trained target disaster identification model for disaster identification, and then the corresponding disaster identification result is output. In the present application, by collecting and analyzing the sound signals in the integrated pipe corridor, the identification and early warning of possible disasters in the integrated pipe corridor are realized, the method for risk identification of the integrated pipe corridor is improved, and the timeliness and accuracy of risk identification of the integrated pipe corridor are effectively improved.
[0061] In the above embodiment, the acquisition of the sample sound signal can be combined with Figure 2 Further understanding, Figure 2 This is a flow chart of a method for identifying risks of integrated pipe corridors based on sound signal visualization according to another embodiment of the present application. Figure 2 As shown, the method includes:
[0062] S201 collects real sound signals before and during the occurrence of various disasters in the integrated pipeline corridor.
[0063] In the actual integrated pipeline corridor scenario, different types of disasters are accompanied by different sounds. In order to accurately identify the risks in the integrated pipeline corridor, the real sound signals of various types of disasters in the integrated pipeline corridor during their occurrence can be collected.
[0064] The real sound signals collected during the occurrence of various types of disasters may include real sound signals before and during the occurrence of the disaster.
[0065] In implementation, the occurrence process of different types of disasters is accompanied by changes in sound. Therefore, based on the characteristics of the real sound signals collected at different occurrence stages, the change process of the real sound signals of different types of disasters during their occurrence can be obtained, thereby achieving accurate extraction of the sound signal characteristics of different types of disasters.
[0066] S202, simulating the sounds before and during the occurrence of various disasters in the integrated pipeline corridor to generate simulated sound signals.
[0067] In the implementation, since the frequency of occurrence of each type of disaster is relatively small in the actual scenario of the integrated pipeline corridor, the sample set generated based on the real sound signals corresponding to different types of disasters collected cannot meet the training requirements of the disaster recognition model based on the deep learning target detection algorithm.
[0068] In an embodiment of the present application, a corresponding simulation environment can be built based on the actual scenario of the integrated pipeline corridor, and different types of disasters that may occur in the integrated pipeline corridor can be simulated in the built simulation environment. During the occurrence of the simulated disaster, the accompanying sound signals can be collected to generate simulated sound signals corresponding to different types of disasters.
[0069] S203: Generate a sample sound signal based on the real sound signal and the simulated sound signal.
[0070] In an embodiment of the present application, the collected real sound signals and simulated sound signals can be further processed to achieve the purpose of training a disaster recognition model based on a deep learning target detection algorithm based on the collected sound signals.
[0071] Furthermore, pre-emphasis processing operations, frame processing operations, windowing processing operations and noise reduction processing operations may be performed on real sound signals and simulated sound signals.
[0072] Among them, the collected real sound signal and analog sound signal can be pre-emphasized, so as to emphasize the high-frequency part of the real sound signal and the analog sound signal, thereby increasing the high-frequency resolution of the real sound signal and the analog sound signal.
[0073] Optionally, the pre-emphasis processing operation on the real sound signal and the analog sound signal can be implemented by a first-order high-pass digital filter.
[0074] Furthermore, the real sound signal and the analog sound signal after pre-emphasis can be windowed and framed, and the collected real sound signal and the analog sound signal can be framed based on a movable window of a set length, thereby generating a number of short-segment sound signals.
[0075] For example, the frame length is set to 200 frames, the frame shift is set to 80 frames, and the collected real sound signal and simulated sound signal are framed using a Hamming window of a set length, thereby generating a number of short sound signals of 200 frames in length.
[0076] Furthermore, noise reduction processing may be performed on a number of short-segment sound signals generated based on the collected real sound signals and simulated sound signals.
[0077] The start and end points of each short segment of the sound signal can be determined by using a sound signal endpoint detection method. Optionally, the short-time energy and short-time zero-crossing rate methods can be used to detect the endpoints of the sound signal.
[0078] Furthermore, noise reduction processing is performed on the sound signal of each short segment with a determined start and end point.
[0079] Optionally, a wavelet threshold method may be used to implement noise reduction processing of the sound signal.
[0080] Furthermore, based on further processing operations on the collected real sound signal and the simulated sound signal, a corresponding sample sound signal is generated.
[0081] Optionally, a corresponding integrated pipe gallery disaster database based on sound information may be constructed, and the generated sample sound signals may be stored in a set location therein.
[0082] The integrated pipe corridor risk identification method based on sound signal visualization proposed in this application collects real sound signals before and during the occurrence of disasters from the actual scene of the integrated pipe corridor, and collects simulated sound signals before and during the occurrence of disasters from the simulated environment of the integrated pipe corridor, and generates corresponding sample sound signals by pre-processing the real sound signals and simulated sound signals such as pre-emphasis, windowing, framing, and noise reduction. In this application, the number of samples for disaster model training is effectively increased by collecting simulated sound signals, and the corresponding sample sound signals are generated by pre-processing the real sound signals and simulated sound signals, thereby effectively enhancing the accuracy of the results generated by subsequent operations based on the sample sound signals.
[0083] In the above embodiment, the sample image can also be combined with Figure 3 Further understanding, Figure 3 This is a flow chart of a method for identifying risks of integrated pipe corridors based on sound signal visualization according to another embodiment of the present application. Figure 3 As shown, the method includes:
[0084] S301, generating a corresponding virtual sound spectrogram based on the sound spectrogram of the sample sound signal.
[0085] In an embodiment of the present application, in order to extract the features of the sample sound signal more accurately and completely, it can be converted into a corresponding sound spectrogram, based on the extraction of the image morphology and features corresponding to the sound signals of different types of disasters in the sound spectrogram, thereby achieving the determination of the features of the sound signals of different types of disasters.
[0086] In the implementation, there may be a situation where the number of sound spectrograms generated based on the sample sound signal is small. Therefore, the sound spectrogram can be further processed to increase the number of sample images, thereby enabling the disaster recognition model based on the deep learning target detection algorithm to obtain effective model training.
[0087] Optionally, the sound spectrogram corresponding to the sample sound signal can be flipped, rotated and scaled, and the presentation angle of the sound spectrogram can be adjusted while retaining the target form and target features in the original sound spectrogram. Further, the flipped, rotated and scaled sound spectrogram can be determined as a virtual sound spectrogram.
[0088] Optionally, the part of the sound spectrogram corresponding to the sample sound signal that has the target form and characteristics can be intercepted and randomly spliced with the sound spectrogram corresponding to the sound signal in the normal operation scenario of the integrated pipeline corridor, so as to generate the corresponding virtual sound spectrogram.
[0089] Furthermore, the sound spectrogram corresponding to the sample sound signal and the generated virtual sound spectrogram are determined as sample images for training a disaster recognition model based on a deep learning target detection algorithm.
[0090] S302, taking the sound spectrogram and the virtual sound spectrogram as sample images, and marking the sample images with detection frames according to the disaster information corresponding to the sample sound signals.
[0091] In an embodiment of the present application, in order to enable the sample images to realize effective training of the disaster recognition model, the target forms corresponding to the sound signals of different types of disasters in the sample images can be marked with detection boxes based on the disaster information corresponding to the sample sound signals.
[0092] It can be understood that, according to the target morphology and target features of the sound signals of different types of disasters in the sample sound signals shown in the sound spectrogram, the part of the sample image with similar morphology and features is determined and marked with a detection frame.
[0093] The integrated pipeline corridor risk identification method based on sound signal visualization proposed in this application effectively increases the number of sample images through further image processing of the sound spectrogram, thereby optimizing the training effect of the disaster identification model based on the deep learning target detection algorithm.
[0094] Furthermore, the output result of the target disaster identification model is corrected for missed detection, which can be combined with Figure 4 understand, Figure 4 This is a flow chart of a method for identifying risks of integrated pipe corridors based on sound signal visualization according to another embodiment of the present application. Figure 4 As shown, the method includes:
[0095] S401, inputting the sound spectrogram to be identified into the target disaster identification model to output a predicted detection box corresponding to the sound spectrogram to be identified.
[0096] It should be noted that the network structure of the constructed disaster identification model is similar to the target detection network (YOLOV3 network), target detection network (Region-CNN network), target detection network (Faster Region-CNN network), target detection network (SSD network), etc. First, it is a skeleton network composed of multiple feature extraction layers, and then passes through multiple convolutional layers, and then through multiple downsampling combinations, finally forming detection layers of different scales.
[0097] In the implementation, it is first necessary to statistically analyze the distribution of the annotation box sizes of the target forms corresponding to various types of disasters in the annotation results, and then determine the network structure of the disaster recognition model, including the feature extraction skeleton, detection layer, and fusion layer, based on the target size and feature complexity of the target in the sample image.
[0098] In the implementation, after the network structure of the disaster identification model is determined, the sample image and its corresponding annotation results are input into the disaster identification model to be trained, and then the disaster identification model to be trained is trained. After the training is completed, the target disaster identification model is obtained.
[0099] Furthermore, the sound spectrogram to be identified is input into the target disaster identification model, and the predicted detection box of the sound spectrogram to be identified is output.
[0100] During the acquisition of sound signals, the sound signals may be unstable, which may cause the target shape and features in the generated sound spectrogram to be identified to be fuzzy. Therefore, when the target disaster identification model identifies the sound spectrograms corresponding to the sound signals of different types of disasters, there is a possibility of missed detection.
[0101] Furthermore, the output results of the target disaster identification model can be corrected for missed detection, thereby achieving comprehensive and accurate identification of disasters.
[0102] Furthermore, since the target disaster recognition model realizes the target morphological recognition of different types of disasters in the sound spectrogram to be recognized by generating a prediction detection frame, the missed detection correction of the target disaster model can be realized based on the prediction detection frame output after the recognition is completed.
[0103] S402, obtaining a labeled detection box i that is missed by the target disaster recognition model, and obtaining a predicted detection box i-1 and a predicted detection box i+1 adjacent to the labeled detection box i.
[0104] In the embodiment of the present application, the missed detection in the spectrogram can be corrected based on the predicted detection box in the same sound spectrogram to be recognized.
[0105] In implementation, sound signals are continuously generated and propagated during the disaster process. Therefore, the target form and features of the sound signals of each type of disaster in the sound spectrogram to be identified have certain regularity and continuity.
[0106] It can be understood that the development of various disasters is relatively stable in a short period of time, and the target shapes of the corresponding sound signals presented in the sound spectrogram to be identified are similar in size and close in interval.
[0107] Furthermore, the missed detection situation can be corrected based on the above characteristics.
[0108] Optionally, by comparing the annotated detection box of the same sound spectrogram to be recognized with the predicted detection box output by the model, the missed annotated detection box i can be obtained, and the predicted detection boxes i-1 and i+1 adjacent to it can be obtained.
[0109] S403 , based on the attribute information of the predicted detection box i-1 and the predicted detection box i+1, determine the attribute information of the predicted detection box i corresponding to the labeled detection box i.
[0110] In the embodiment of the present application, after the predicted detection box i-1 and the predicted detection box i+1 are determined, the attribute information of the predicted detection box i corresponding to the missed labeled detection box i can be determined based on the attribute information of the two predicted detection boxes.
[0111] Optionally, since the target shape and features corresponding to the missed labeled detection frame i are similar to the target shapes and features in the predicted detection frame i-1 and the predicted detection frame i+1, the size information of the two predicted detection frames can be used to calculate the size information of the predicted detection frame i corresponding to the missed labeled detection frame i, and based on the coordinate information of the central pixel points of the two predicted detection frames, the coordinate information of the central pixel point of the predicted detection frame i corresponding to the missed labeled detection frame i can be calculated.
[0112] For example, assume that n labeled detection frames are annotated in the sample image, among which the target shape corresponding to the i-th labeled detection frame is missed.
[0113] Then the center pixel coordinates (x i ,y i ) is calculated as follows:
[0114]
[0115] Then the length L of the predicted detection box i corresponding to the i-th labeled detection box i The calculation formula is as follows:
