[0037] Transmission lines are important facilities in the power system used to transmit electric energy from power plants and substations to distribution networks or other substations. They undertake the key task of long-distance and large-capacity electric energy transmission.

[0038] In the existing technology, most of the transmission lines are monitored by operation and maintenance personnel to avoid transmission line failures caused by external hidden dangers.

[0039] However, this method of monitoring the transmission lines by operation and maintenance personnel has poor timeliness, which in turn leads to poor monitoring efficiency of the transmission lines.

[0040] In view of this, the present application provides a method for monitoring transmission lines, which realizes the monitoring of transmission lines based on the fluctuation information of spare communication optical fibers, video data of vibration events, and audio data of vibration events. Compared with the existing technology of monitoring transmission lines by operation and maintenance personnel, the timeliness of transmission line monitoring is improved, thereby improving the monitoring efficiency of transmission lines.

[0041] The transmission line monitoring method provided in the present application may be executed by a computer device, which may be a terminal or a server.

[0042] In an exemplary embodiment, Figure 1 As shown, a method for monitoring a transmission line is provided, the method comprising the following steps:

[0043] Step 101: Acquire fluctuation information of a spare communication optical fiber in a target power transmission line, and determine first event type information of a vibration event and location information of the vibration event according to the fluctuation information.

[0044] The backup communication optical fiber is installed at the same position as the cable in the target transmission line.

[0045] Optionally, the backup communication optical fiber refers to a redundant optical fiber that is not used for regular communication services among the communication optical fibers laid in the target power transmission line.

[0046] For example, the backup communication fiber is used to replace the primary communication fiber when it fails. Furthermore, since the backup communication fiber is idle, it can be reused as a distributed fiber optic sensing medium to monitor physical quantities such as environmental vibration and temperature changes around the target transmission line.

[0047] Optionally, the fluctuation information refers to information about changes in characteristics of optical signals transmitted by the backup communication optical fiber under external disturbances, and the external disturbances may be vibrations, shocks, temperature changes, and the like.

[0048] Exemplarily, the fluctuation information may include light intensity fluctuation, phase fluctuation, and polarization state fluctuation. Light intensity fluctuation refers to changes in the intensity of the optical signal in the backup communication fiber due to vibration-induced microbending and stretching of the fiber; phase fluctuation refers to the phase shift caused by external vibration interference when light propagates in the backup communication fiber; and polarization state fluctuation refers to changes in the polarization direction of light when the backup communication fiber is affected by vibration.

[0049] Optionally, a vibration event refers to a vibration phenomenon of the power transmission line or the surrounding environment caused by external factors and monitored through the backup communication optical fiber. For example, the external factors may be human factors, such as construction machinery operation, vehicle collision with a tower, and personnel climbing.

[0050] Furthermore, the first event type information refers to information determined based on the fluctuation information and can be used to indicate the type of the vibration event, such as construction machinery operation, vehicle collision with a pole tower, and personnel climbing.

[0051] The location information of the vibration event indicates the location where the vibration event occurred. For example, this location information can be tower-associated positioning information, such as the tower number and interval description, "between towers #15 and #16 on the 220kV XX line." It can also be a geographic area identifier, such as an administrative division and a specific location, such as "a transmission line section within the industrial park of XX Town, XX District, XX City," or "a river-crossing section in the farmland area of ​​XX Township, XX County." It can also be specific longitude and latitude.

[0052] In some exemplary embodiments, the computer device first obtains fluctuation information of a backup communication optical fiber in a target power transmission line.

[0053] Specifically, the backup communication optical fiber in the target power transmission line can be connected to the distributed fiber optic acoustic wave sensing system, and the computer device can use the distributed fiber optic acoustic wave sensing system to obtain the fluctuation information of the backup communication optical fiber in the target power transmission line.

[0054] Furthermore, after obtaining the fluctuation information of the backup communication optical fiber in the target power transmission line, the computer device may determine first event type information of the vibration event according to the fluctuation information.

[0055] Specifically, after obtaining the fluctuation information of the backup communication optical fiber in the target transmission line, the computer device can input the fluctuation information into a pre-trained event type analysis model to obtain the first event type information of the vibration event output by the event type analysis model.

[0056] After obtaining the fluctuation information of the spare communication optical fiber in the target power transmission line, the computer device can also determine the location information of the vibration event according to the fluctuation information.

[0057] Specifically, the computer device can use the physical properties of light propagating in optical fibers in combination with a signal processing algorithm to determine the position information of the vibration event.

[0058] The computer device may also input the fluctuation information into a pre-trained position information analysis model to obtain the position information of the vibration event output by the position information analysis model.

[0059] Step 102: Acquire video data of the vibration event based on the position information, and determine second event type information of the vibration event according to the video data.

[0060] Optionally, the video data of a vibration event refers to dynamic image data captured by a video acquisition device at a specific location where the vibration event occurs, which can record the vibration phenomenon at that location and the surrounding environment.

[0061] Optionally, the second event type information refers to information determined based on video data and can be used to indicate the type of the vibration event.

[0062] In some exemplary embodiments, after determining the location information of the vibration event, the computer device may obtain video data of the vibration event based on the location information.

[0063] Specifically, the computer device obtains the video data of the vibration event based on the location information and the monitoring device.

[0064] Furthermore, after acquiring the video data of the vibration event based on the position information, the computer device may determine second event type information of the vibration event according to the video data.

[0065] Specifically, the computer device can input the video data into a pre-trained event type analysis model to obtain second event type information of the vibration event output by the event type analysis model. The event type analysis model can be a lightweight YOLO model, which can also analyze the video data to identify the presence of large construction equipment, personnel activities, wearing identification, etc., and analyze behavioral characteristics, such as standing still, approaching slowly, and lifting tools to operate.

[0066] Step 103: Acquire audio data of the vibration event based on the video data, and determine third event type information of the vibration event according to the audio data.

[0067] Optionally, the audio data of the vibration event refers to sound signal data related to the vibration event.

[0068] Optionally, the third event type information refers to information determined based on audio data and can be used to indicate the type of the vibration event.

[0069] In some exemplary embodiments, after obtaining the video data of the vibration event, the computer device may acquire the audio data of the vibration event based on the video data.

[0070] Specifically, the computer device can obtain the audio data of the vibration event from the video data. In an optional embodiment of the present application, the computer device can also obtain the audio data of the vibration event through an audio acquisition device based on the location information of the vibration event, such as a distributed fiber optic acoustic wave sensing system.

[0071] Furthermore, after acquiring the audio data of the vibration event based on the video data, the computer device may determine third event type information of the vibration event according to the audio data.

[0072] Specifically, the computer device may input the audio data into a pre-trained event type analysis model to obtain the third event type information of the vibration event output by the event type analysis model.

[0073] Step 104: Determine the risk level of the vibration event based on the first event type information, the second event type information, and the third event type information, and determine a target security policy based on the risk level.

[0074] Optionally, the risk level of the vibration event may be used to characterize the degree of threat posed by the vibration event to the safety of the target transmission line.

[0075] Target safety strategy refers to specific measures or plans formulated based on the risk level of vibration events to prevent, mitigate or handle the vibration events.

[0076] For example, assuming that the risk level of the vibration event includes three levels, namely low risk level, medium risk level and high risk level, if the risk level of the vibration event is low risk level, then the target safety strategy can be conventional measures such as continuous monitoring and regular inspections; if the risk level of the vibration event is medium risk level, then the target safety strategy can be interference measures such as on-site warnings and removal of interference sources; if the risk level of the vibration event is high risk level, then the target safety strategy can be emergency shutdown and maintenance, temporary power off protection, on-site disposal by dispatch personnel and other emergency measures.

[0077] In some exemplary embodiments, after obtaining the first event type information, the second event type information, and the third event type information, the computer device may determine the risk level of the vibration event based on the first event type information, the second event type information, and the third event type information.

[0078] Furthermore, after determining the risk level of the vibration event, the computer device may determine a target security policy according to the risk level.

[0079] Specifically, the computer device may determine the target security policy using a risk level-security policy mapping relationship list and the risk level. The risk level-security policy mapping relationship list may be as shown in Table 1.

[0081]

[0082] The above-mentioned transmission line monitoring method first obtains the fluctuation information of the backup communication optical fiber in the target transmission line, and determines the first event type information of the vibration event and the location information of the vibration event based on the fluctuation information. The backup communication optical fiber is set at the same position as the cable in the target transmission line. Then, based on the location information, the video data of the vibration event is obtained, and the second event type information of the vibration event is determined based on the video data. Then, based on the video data, the audio data of the vibration event is obtained, and the third event type information of the vibration event is determined based on the audio data. Finally, the risk level of the vibration event is determined based on the first event type information, the second event type information, and the third event type information, and the target safety strategy is determined based on the risk level. The transmission line monitoring method provided in the present application realizes the monitoring of the transmission line based on the fluctuation information of the backup communication optical fiber, the video data of the vibration event, and the audio data of the vibration event. Compared with the monitoring of the transmission line by operation and maintenance personnel in the prior art, the timeliness of the transmission line monitoring is improved, thereby improving the monitoring efficiency of the transmission line.

[0083] In an exemplary embodiment, Figure 2 As shown, determining first event type information of a vibration event according to fluctuation information includes the following steps:

[0084] Step 201: Determine frequency information, duration information, envelope feature information, and spectrum morphology information of a vibration event based on fluctuation information.

[0085] Optionally, the frequency information of the vibration event refers to the number of vibrations per unit time. The envelope characteristic information of the vibration event refers to the overall profile of the vibration signal in terms of amplitude variation, i.e., the vibration intensity. The spectral morphology information of the vibration event refers to the energy distribution of the vibration signal after it is converted to the frequency domain through methods such as Fourier transform.

[0086] In some exemplary embodiments, after obtaining the fluctuation information, the computer device may determine frequency information, duration information, envelope characteristic information, and spectrum morphology information of the vibration event based on the fluctuation information.

[0087] Specifically, the computer device may utilize a Fourier transform algorithm or a short-time Fourier transform algorithm to determine frequency information of the vibration event based on the fluctuation information. The computer device may also utilize a Hilbert transform algorithm to determine envelope characteristic information of the vibration event based on the fluctuation information. The computer device may also generate a spectrogram based on the fluctuation information and determine spectral morphology information of the vibration event based on the spectrogram.

[0088] Step 202: Determine first event type information of the vibration event based on the frequency information, duration information, envelope feature information, and spectrum morphology information.

[0089] In some exemplary embodiments, after obtaining the frequency information, duration information, envelope characteristic information and spectrum morphology information of the vibration event, the computer device can determine the first event type information of the vibration event based on the frequency information, duration information, envelope characteristic information and spectrum morphology information.

[0090] Specifically, the computer device can input the frequency information, duration information, envelope feature information and spectrum morphology information of the vibration event into a pre-trained event type analysis model to obtain the first event type information of the vibration event output by the event type analysis model.

[0091] In an optional embodiment of the present application, when the first event type information of the vibration event is the presence of suspicious mechanical vibration, the computer device executes the steps of obtaining video data of the vibration event based on the position information and determining the second event type information of the vibration event based on the video data, otherwise it is not executed.

[0092] Alternatively, the event type analysis model can also output the event intensity of the vibration event. Only when the event intensity is greater than a preset threshold value, the computer device executes the steps of obtaining the video data of the vibration event based on the position information and determining the second event type information of the vibration event based on the video data. Otherwise, it will not be executed.

[0093] In an exemplary embodiment, Figure 3 As shown, obtaining video data of a vibration event based on position information includes the following steps:

[0094] Step 301: Determine a target shooting device from a plurality of shooting devices arranged around a target transmission line according to location information.

[0095] In some exemplary embodiments, after obtaining the location information of the vibration event, the computer device may determine a target shooting device from a plurality of shooting devices disposed around the target power transmission line according to the location information.

[0096] Specifically, the computer device can use the location-capturing device mapping relationship list to determine the target capturing device from multiple capturing devices arranged around the target transmission line according to the location information. The location-capturing device mapping relationship list can be shown in Table 2.

[0097] Table 2

[0098]

[0099] Step 302: Acquire video data of the vibration event based on the target shooting device.

[0100] In some exemplary embodiments, after determining the target shooting device, the computer device may acquire video data of the vibration event based on the target shooting device.

[0101] Specifically, the computer device can send a retrieval request to the video stream server, and the retrieval request carries the identification information of the target shooting device, so that the video stream server retrieves the video surveillance stream of the target shooting device within a preset time range based on the identification information and sends it to the computer device. The preset time range can be pre-set by the technician according to actual needs, for example, 10s, 20s, etc. The video surveillance stream is the video data of the vibration event.

[0102] In an exemplary embodiment, Figure 4 As shown, obtaining audio data of a vibration event based on video data includes the following steps:

[0103] Step 401: Obtain the duration of the vibration event.

[0104] In some exemplary embodiments, the computer device may first obtain the duration of the vibration event.

[0105] Specifically, the computer device may determine the duration of the vibration event according to the fluctuation information.

[0106] Step 402: When the duration is greater than a preset time threshold, obtain audio data of the vibration event based on the video data.

[0107] Optionally, the preset time threshold may be pre-set by a technician according to actual needs, such as 10s, 20s, etc.

[0108] In some exemplary embodiments, after obtaining the duration of the vibration event, the computer device may determine whether the duration is greater than a preset time threshold.

[0109] Furthermore, if the computer device determines that the duration is greater than a preset time threshold, the computer device obtains audio data of the vibration event based on the video data.

[0110] In an exemplary embodiment, Figure 5 As shown, determining the third event type information of the vibration event according to the audio data includes the following steps:

[0111] Step 501: Compare the audio data with a plurality of preset voiceprint templates in a preset voiceprint template library to obtain comparison results.

[0112] Optionally, the multiple preset voiceprint templates in the preset voiceprint template library are audio data of different types of vibration events.

[0113] In some exemplary embodiments, after obtaining the audio data, the computer device may compare the audio data with a plurality of preset voiceprint templates in a preset voiceprint template library to obtain a comparison result.

[0114] Specifically, the preset voiceprint template library stores a plurality of preset voiceprint templates, and the computer device can respectively determine the similarity between the audio data and the plurality of preset voiceprint templates, and determine the similarity as the comparison result.

[0115] The computer device can also use a lightweight similarity learning method to compare the audio data with multiple preset voiceprint templates in a preset voiceprint template library to obtain a comparison result.

[0116] Step 502: Determine third event type information of the vibration event according to the comparison result.

[0117] In some exemplary embodiments, after obtaining the comparison result, the computer device may determine third event type information of the vibration event according to the comparison result.

[0118] Specifically, the computer device may determine the label corresponding to the preset voiceprint template with the highest similarity as the third event type information of the vibration event.

[0119] In an exemplary embodiment, the risk level of a vibration event is determined based on first event type information, second event type information, and third event type information, including: inputting the first event type information, the second event type information, and the third event type information into a pre-trained risk identification model to obtain the risk level of the vibration event output by the risk identification model.

[0120] Optionally, the risk identification model can be a fusion network based on Transformer and adopt a cross-attention mechanism.

[0121] In some optional embodiments, the second event type information and the third event type information both include event type and confidence level.

[0122] In some exemplary embodiments, after obtaining the first event type information, the second event type information, and the third event type information, the computer device may input the first event type information, the second event type information, and the third event type information into a pre-trained risk identification model to obtain the risk level of the vibration event output by the risk identification model.

[0123] Specifically, the risk identification model may first determine the target type and comprehensive confidence of the vibration event based on the first event type information, the second event type information, and the third event type information, and then determine the risk level of the vibration event based on the target type and the comprehensive confidence.

[0124] For example, if the comprehensive confidence is greater than the first preset confidence threshold, the risk level is output; if the comprehensive confidence is less than the first preset confidence threshold but greater than the second preset confidence threshold, a suspicious event record is generated; if the comprehensive confidence is less than the second preset confidence threshold, it is regarded as a normal disturbance and no processing is performed.

[0125] In some optional embodiments of the present application, after the risk identification model outputs the risk level, the computer device can upload the time, location, type, image screenshots, audio summary, etc. of the vibration event to the monitoring platform, and simultaneously generate an edge cache file to record the image and audio files 30 seconds before and after for subsequent evidence collection.

[0126] Furthermore, the computer device can also store the risk level in the event log library and perform label correction based on manual review feedback.

[0127] In an exemplary embodiment, Figure 6 As shown, another method for monitoring a transmission line is provided, the method comprising the following steps:

[0128] Step 601: Obtain fluctuation information of a backup communication optical fiber in a target transmission line, and determine frequency information, duration information, envelope characteristic information, and spectral morphology information of a vibration event based on the fluctuation information; determine first event type information of the vibration event based on the frequency information, duration information, envelope characteristic information, and spectral morphology information; the backup communication optical fiber is located in the same position as the cable in the target transmission line;

[0130] Step 603: Obtain the duration of the vibration event; if the duration is greater than a preset time threshold, obtain audio data of the vibration event based on the video data, and compare the audio data with multiple preset voiceprint templates in a preset voiceprint template library to obtain comparison results; determine third event type information of the vibration event based on the comparison results;

[0131] Step 604: Input the first event type information, the second event type information, and the third event type information into a pre-trained risk identification model to obtain the risk level of the vibration event output by the risk identification model.
