Description

Technical Field

[0001] The present invention relates to the field of optical fiber sensing, and more specifically, to an optical cable route survey method. Background Art

[0002] With the continuous development of optical cable communication technology, the scale of optical cable communication network is constantly expanding. The number of optical cables installed in optical cable equipment or optical cable facilities such as machine rooms, optical cross boxes, optical cable wells, and optical cable poles ranges from a few to hundreds. In order to ensure the normal operation of the optical cable communication network, it is necessary to conduct a census of the optical cable routing information of the above-mentioned optical cable equipment and optical cable facilities. However, due to the large scale of optical cables, the census of optical cable information is very cumbersome and difficult. Summary of the invention

[0003] The present invention aims to overcome at least one defect of the above-mentioned prior art and provide a method for surveying optical cable routes to improve the survey efficiency of optical cable route information.

[0004] The technical solution adopted by the present invention is:

[0005] In a first aspect, the present invention provides a method for surveying optical cable routes, the method comprising:

[0006] Obtaining a first convex wave peak in the optical fiber real-time waveform window, and confirming the optical cable distance range of the route survey location point according to the first convex wave peak; the first convex wave peak is generated by a first test tapping on the route survey location point;

[0007] Taking the optical cable distance range as a base point, confirming the distance display interval of the optical fiber real-time waveform window;

[0008] A detection peak is obtained within the distance display interval; the detection peak is generated by a detection tapping on the route survey location point; the detection tapping is multiple tappings within a preset time;

[0009] confirming a candidate optical cable distance point in the detection peak and displaying a time domain waveform of the candidate optical cable distance point;

[0010] When the peak in the time domain waveform is consistent with the regularity of the detection knocking, it is confirmed that the route survey location point belongs to the optical cable routing point.

[0011] By observing and obtaining the first raised peak in the optical fiber real-time waveform window, the approximate optical cable distance range of the route survey position point on the optical cable can be obtained according to the first raised peak; after determining the approximate optical cable distance range, by confirming the distance display interval of the optical fiber real-time waveform window, the real-time waveform of the route survey position point can be more intuitively observed, and then the detection peak can be observed in the distance display interval, and the candidate optical cable distance point and the time domain waveform of the candidate optical cable distance point can be obtained from the detection peak, and the time domain waveform can reflect the vibration of the candidate optical cable distance point. After obtaining the vibration of the candidate optical cable distance point, the vibration is judged with the law of the detection knocking, so as to accurately judge whether the candidate optical cable distance point matches the route survey point, and then accurately realize the positioning of the optical cable distance of the route survey point of the optical cable on the optical cable, effectively improving the survey efficiency of the optical cable.

[0012] Furthermore, the step of confirming the distance display interval of the optical fiber real-time waveform window based on the optical cable distance range includes:

[0013] Taking the optical cable distance range as a base point, narrowing the distance display interval of the optical fiber real-time waveform window;

[0014] When a second raised wave peak is detected within the distance display interval, it is confirmed that the route survey location point is within the distance display interval; the second raised wave peak is generated by a second test tapping on the route survey location point.

[0015] By reducing the distance display interval of the optical fiber real-time waveform window, that is, amplifying the real-time waveform of the optical cable, the second test knock and the vibration of the detection knock on the real-time waveform can be more clearly observed and analyzed, thereby improving the efficiency of detection.

[0016] Furthermore, when the peak in the time domain waveform is consistent with the regularity of the detected knocking, the step of confirming that the route survey location point belongs to the optical cable route point includes:

[0017] Obtaining the number of peaks of the time domain waveform within the preset time;

[0018] When the number of wave peaks is consistent with the number of detection knocks, it is confirmed that the route survey location point belongs to the optical cable routing point.

[0019] The time domain waveform can reflect the vibration condition of the candidate optical cable distance point. When the detection vibration is applied to the route survey location point, the time domain waveform will generate corresponding peaks. By obtaining the peak data within a preset time on the time domain waveform and comparing the number of peaks with the number of detection knocks, it is possible to intuitively and effectively determine whether the route survey location point belongs to the route point of the optical cable. At the same time, obtaining the number of peaks within the preset time can effectively avoid the influence of other unnecessary vibrations and improve the accuracy of detection.

[0020] Furthermore, when the peak in the time domain waveform is consistent with the rule of the detection knocking, after the step of confirming that the route survey location point belongs to the optical cable route point, it also includes:

[0021] Obtaining a verification wave peak in the time domain waveform; the verification wave peak is generated by a verification tapping on the route survey location point;

[0022] When the verification wave peak is consistent with the regularity of the verification tapping, the verification of the route survey position point is completed.

[0023] After the candidate optical cable distance point is determined by the detection tapping, the determination result of the detection tapping is verified by the verification tapping to further improve the accuracy of the route survey.

[0024] Further, after the step of confirming that the route survey location point belongs to the optical cable route point, it also includes:

[0025] Using the distance data corresponding to the candidate optical cable distance point as the detection distance of the route survey location point;

[0026] Obtaining the latitude and longitude data of the route survey location point;

[0027] The latitude and longitude data and the detection distance are uploaded to a server.

[0028] By uploading the latitude and longitude to the server, it is helpful to locate the route survey point on the map, which facilitates the generation of optical cable routing lines after the subsequent completion of the optical cable routing survey.

[0029] Furthermore, before the step of confirming the candidate optical cable distance point in the detection peak and displaying the time domain waveform of the candidate optical cable distance point, the method further includes:

[0030] Within the preset time, time domain data of multiple optical cable distance points within the sliding distance interval are collected at preset intervals; the time domain data are used to generate corresponding time domain waveforms; the sliding distance interval is determined based on the collection start distance or the distance of the previous optical cable routing point.

[0031] Furthermore, after the step of confirming the candidate optical cable distance point in the detection peak and displaying the time domain waveform of the candidate optical cable distance point, the method further includes:

[0032] When the peak in the time domain waveform is inconsistent with the regularity of the detection knocking, obtaining a verification peak in the time domain waveform; the verification peak is generated by the verification knocking acting on the route survey location point;

[0033] When the verification wave peak is consistent with the pattern of the verification knocking, it is confirmed that the route survey position point belongs to the optical cable routing point.

[0034] Further, after the step of confirming that the route survey location point belongs to the optical cable route point, the method further includes:

[0035] Displaying the frequency domain waveform of the candidate optical cable distance point;

[0036] When a characteristic frequency peak exists in the frequency domain waveform, the optical cable entity corresponding to the optical cable routing point is confirmed; the characteristic frequency peak is formed by the optical cable entity located at the routing survey position point vibrating with the characteristic frequency.

[0037] After confirming the optical cable routing point, by acquiring and displaying the frequency domain waveform of the candidate optical cable distance point, the specific optical cable entity in the optical cable routing point can be effectively acquired and confirmed by applying characteristic frequency vibrations on the optical cable.

[0038] Furthermore, before the step of obtaining the first convex peak in the optical fiber real-time waveform window, the method further includes:

[0039] Enter the vibration waveform page; the vibration waveform page includes the optical fiber real-time waveform window and the time domain waveform window.

[0040] Furthermore, the step of entering the vibration waveform page includes:

[0041] Confirm the optical cables to be surveyed and the survey starting point;

[0042] Configure the host ID and device port corresponding to the optical cable to be surveyed;

[0043] Enter the vibration waveform page based on the host ID and the device port.

[0044] A second aspect of the present invention further provides an optical cable route survey system, the survey system comprising:

[0045] A waveform range acquisition module, used to acquire a first convex wave peak in the optical fiber real-time waveform window, and confirm the optical cable distance range of the route survey location point according to the first convex wave peak; the first convex wave peak is generated by a first test tapping on the route survey location point;

[0046] An interval confirmation module, used to confirm the distance display interval of the optical fiber real-time waveform window based on the optical cable distance range;

[0047] A peak extraction module, used for obtaining a detection peak within the distance display interval; the detection peak is generated by a detection tapping on the route survey location point; the detection tapping is a plurality of tappings within a preset time;

[0048] A time domain display module, used to confirm a candidate optical cable distance point in the detection peak and display a time domain waveform of the candidate optical cable distance point;

[0049] The vibration analysis module is used to confirm that the route survey location point belongs to the optical cable route point when the peak in the time domain waveform is consistent with the law of the detected knocking.

[0050] According to a third aspect of the present invention, there is provided an electronic device, comprising a memory and a processor, wherein the memory stores computer-readable instructions, and when the processor executes the computer-readable instructions, the optical cable route survey method described in the first aspect is implemented.

[0052] Compared with the prior art, the present invention has the following beneficial effects:

[0053] The present invention applies a first test strike to a route survey position point of an optical cable in advance, and observes a first convex wave peak generated under the action of the first test strike in an optical fiber real-time waveform window, so that the optical cable distance range of the route survey position point can be quickly obtained through the first convex wave peak; after obtaining the optical cable distance range, by observing the distance display interval of the optical fiber real-time waveform window in the optical cable distance range, the real-time waveform of the route survey position point can be more intuitively observed, and then the detection wave peak can be observed in the distance display interval, and a candidate optical cable distance point and a time domain waveform of the candidate optical cable distance point can be obtained from the detection wave peak, and the time domain waveform can reflect the vibration of the candidate optical cable distance point, and after obtaining the vibration of the candidate optical cable distance point, the vibration is judged with the law of the detection strike, so that it can be accurately judged whether the candidate optical cable distance point matches the route survey point, and then the positioning of the optical cable distance of the route survey point of the optical cable on the optical cable can be accurately realized, and the survey efficiency of the optical cable is effectively improved.

[0062] The drawings of the present invention are only for illustrative purposes and should not be construed as limiting the present invention. In order to better illustrate the following embodiments, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; it is understandable to those skilled in the art that some well-known structures and their descriptions in the drawings may be omitted.

[0063] Example 1

[0064] like Figure 1 As shown, this embodiment provides a method for surveying optical cable routes;

[0065] Specifically, the survey method includes:

[0066] S1: Obtaining a first convex wave peak in the optical fiber real-time waveform window, and confirming the optical cable distance range of the route survey location point according to the first convex wave peak; the first convex wave peak is generated by a first test tapping on the route survey location point;

[0067] Specifically, in this embodiment, before the step of obtaining the first convex crest, the method further includes:

[0068] Enter the vibration waveform page; the vibration waveform page includes the optical fiber real-time waveform window and the time domain waveform window.

[0069] It is understandable that in this embodiment, the survey of the optical cable route is mainly carried out by connecting the optical cable sonar or optical cable line analyzer and other detection equipment with phase-sensitive optical time domain reflectometer to the optical cable to be surveyed at the starting facility point of the survey, such as the optical cable room, optical cross-box, etc., to detect and analyze the vibration or sound waves received by the optical cable. Then, the corresponding vibration is applied to the intermediate facility point where the optical cable to be surveyed may pass, such as the optical cable well or the optical cable rack, and the distance between the position point where the vibration is applied and the survey starting facility point where the detection equipment is located is determined by the detection equipment, and the routing of the optical cable is determined by determining the position point and the corresponding optical cable distance.

[0070] Therefore, in this embodiment, the step of entering the vibration waveform page may specifically include:

[0071] Confirm the optical cables to be surveyed and the survey starting point;

[0072] Configure the host ID and device port corresponding to the optical cable to be inspected; after configuring the host ID and device port, the detection device can be connected to the corresponding device port, so that the detection device can receive the optical cable data of the optical cable to be inspected in real time, and generate a real-time vibration waveform according to the optical cable data;

[0073] Enter the vibration waveform page based on the host ID and the device port; the vibration waveform page is used to display the vibration waveform generated by the detection device according to the optical cable data of the optical cable to be surveyed, so after connecting the detection device to the device interface, the detection device can be accessed and the vibration waveform page can be entered according to the host ID and the device port.

[0074] Preferably, in this embodiment, the detection device can be accessed through mobile devices such as mobile phones and laptop computers, and the system of the detection device can be accessed through the mobile device, and the vibration waveform page can be displayed on the mobile device; wherein, the access connection between the mobile device and the detection device can be achieved through a wireless network such as a 4G / 5G network, so that in the subsequent process of the optical cable route census, the vibration condition of the optical cable to be surveyed can be checked in real time through the vibration waveform page.

[0075] It can be understood that the optical fiber real-time waveform window is mainly used to display the real-time waveform generated by the detection equipment, wherein the real-time waveform is generated by the detection equipment based on the real-time optical cable data of the optical cable to be surveyed, reflecting the overall real-time vibration condition of the optical cable to be surveyed; the time domain waveform window is mainly used to display the change of the vibration waveform of the corresponding position point on the optical cable to be surveyed over time.

[0076] Therefore, in order to clearly and quickly observe the vibration condition of the optical cable to be surveyed at the route survey position point, it is necessary to first determine the distance range of the route survey position point on the optical cable to be surveyed, so the first trial strike is applied at the route survey position point, and the first trial strike acts on the optical cable to be surveyed. If the optical cable to be surveyed passes through the current route survey position point, the corresponding first raised wave peak can be observed at the corresponding cable distance point through the optical fiber real-time waveform window, and then the range contained in the wave peak of the first raised wave peak can be used as the cable distance range of the route survey position point on the optical cable to be surveyed.

[0077] S2: Taking the optical cable distance range as a base point, confirming the distance display interval of the optical fiber real-time waveform window;

[0078] Specifically, the distance display interval of the optical fiber real-time waveform window is adjusted according to the optical cable distance range so that the route survey point falls within the distance display interval. If the optical cable distance range accounts for a low proportion in the current distance display interval, for example, the proportion is lower than the set proportion, the distance display interval of the optical fiber real-time waveform window can be adjusted based on the optical cable distance range, for example, 100 meters before the optical cable distance range and 300 meters after the optical cable distance range are used as the new distance display interval. If the optical cable distance range accounts for a moderate proportion in the current distance display interval, for example, the proportion is within the set range, the current distance display interval can be maintained without change.

[0079] In one example, if Figure 2 As shown, the step of confirming the distance display interval of the optical fiber real-time waveform window based on the optical cable distance range includes:

[0080] S21: Taking the optical cable distance range as a base point, narrowing the distance display interval of the optical fiber real-time waveform window; the distance display interval represents the distance range of the real-time vibration waveform of the optical cable to be surveyed displayed by the optical fiber real-time waveform window. For example, if the distance display interval is 0-100m, it means that the optical fiber real-time waveform window displays the real-time vibration waveform of the optical cable to be surveyed within the range of 0-100m.

[0081] As described above, the optical fiber real-time waveform window displays the overall real-time vibration of the optical cable to be inspected, so in the initial case, the distance display interval is the length of the entire optical cable to be inspected or the preset optical cable length, so that the first raised peak accounts for a small proportion in the optical fiber real-time waveform window, which is not convenient for the subsequent observation of the corresponding knocking waveform; therefore, it is necessary to narrow the distance display interval of the optical fiber real-time waveform window so that the distance display interval of the optical fiber real-time waveform window can roughly match the first raised peak, so that the vibration peak generated by the subsequent knocking can also better fall into the distance display interval for observation.

[0082] S22: When a second raised wave peak is detected within the distance display interval, it is confirmed that the route survey location point is within the distance display interval; the second raised wave peak is generated by a second test tapping on the route survey location point.

[0083] As described above, due to the limited number of times and impact time of the first trial tap, the distance display interval obtained based on the first raised wave peak is not completely accurate. Therefore, the second trial tap can be applied to observe whether the second raised wave peak formed by the second trial tap can match the confirmed distance display interval to ensure that the route survey point falls within the distance display interval.

[0084] It should be noted that if the second raised peak still does not match the distance display interval, the distance display interval can be adjusted according to the second raised peak, moved forward, backward, enlarged or reduced as appropriate, and a third trial knock can be applied to form a corresponding third raised peak for observation.

[0085] S3: obtaining a detection peak within the distance display interval; the detection peak is generated by a detection tapping on the route survey location point; the detection tapping is multiple tappings within a preset time;

[0086] It is understandable that since the route survey is usually conducted outdoors and may be conducted in a noisy environment, during the route survey, the optical cable to be surveyed will not only be affected by the knocking during the route survey, but will also be affected by the vibration or noise of various environments, and the vibration or noise of these environments will interfere with the vibration waveform. Therefore, in this embodiment, the detection knocking is multiple knocking within a preset time, and the number of peaks within the corresponding preset time can be compared with the number of knockings to confirm the location point or location range of the optical cable to be surveyed by the detection knocking, reduce the interference of external environmental vibration and noise, and improve the accuracy of detection. After the detection knocking and the corresponding comparison confirmation, the detection peak is displayed in the distance display interval, or the distance range corresponding to the detection peak is displayed.

[0087] S4: confirming a candidate optical cable distance point in the detection peak and displaying a time domain waveform of the candidate optical cable distance point;

[0088] Specifically, the detection peak may correspond to a position point or a distance range. Therefore, a position point with the maximum vibration intensity or a vibration intensity exceeding a set threshold is obtained in the detection peak as the candidate optical cable position point. After the candidate optical cable position point is obtained, the time domain waveform of the candidate optical cable position point can be obtained and displayed through the time domain waveform window.

[0089] In order to better realize the display of the time domain waveform, before the step of confirming the candidate optical cable distance point in the detection peak and displaying the time domain waveform of the candidate optical cable distance point, it is necessary to obtain the time domain data used to form the time domain waveform, such as Figure 5 As shown, it may specifically include:

[0090] S41: within the preset time, collecting time domain data of multiple optical cable distance points within a sliding distance interval at a preset interval; the time domain data is used to generate a corresponding time domain waveform; wherein the sliding distance interval is determined based on the collection start distance or the distance of the previous optical cable routing point.

[0091] It can be understood that the sliding distance interval is a certain distance range displayed in the optical fiber real-time waveform window starting from the previous census route position point. As the route census proceeds, the sliding distance interval will continue to "slide" backward in the optical fiber real-time waveform window, ensuring that the vibration waveform generated by tapping the current census route position point can be well observed from the optical fiber real-time waveform window.

[0092] Exemplarily, assuming that the current location is the first surveyed route location point, the sliding distance interval can be 0-10km, so that the optical fiber real-time waveform window can display the real-time vibration waveform within the 0-10km optical cable range of the optical cable to be surveyed; when the survey of the first surveyed route location point is completed, and the corresponding distance of the first surveyed route location point on the optical cable to be surveyed is 1km, the sliding distance interval can be 1km-11km. That is, the sliding distance interval slides backward as the survey proceeds, so that the optical fiber real-time waveform window can better display the vibration waveform of the current surveyed route location point.

[0093] S5: When the peak in the time domain waveform is consistent with the pattern of the detected knocking, it is confirmed that the route survey location point belongs to the optical cable route point.

[0094] As described above, the time domain waveform acquired and displayed by the time domain waveform window reflects the change of the vibration waveform of the candidate optical cable distance point over time. Then, if the candidate optical cable distance point corresponds to the route census position point, the number of knocks of the detection vibration applied to the route census position point within the preset time is matched with the number of peaks appearing in the time domain waveform of the candidate optical cable distance point;

[0095] Therefore, in this embodiment, when the peak in the time domain waveform is consistent with the rule of the detected knocking, the step of confirming that the route survey location point belongs to the optical cable route point is as follows: Figure 3 As shown, it may specifically include:

[0096] S51: Obtaining the number of peaks of the time domain waveform within the preset time;

[0097] S52: When the number of wave peaks is consistent with the number of detection knocks, confirm that the route survey location point belongs to the optical cable routing point.

[0098] In a specific implementation, when the peak in the time domain waveform is consistent with the rule of the detection knocking, after the step of confirming that the route survey location point belongs to the optical cable route point, it is also necessary to verify the route survey location point, such as Figure 4 As shown, it may specifically include:

[0099] S53: obtaining a verification peak in the time domain waveform; the verification peak is generated by a verification tapping on the route survey location point;

[0100] S54: When the verification wave peak is consistent with the verification tapping pattern, the verification of the route survey position point is completed.

[0101] The regularity judgment content of the verification peak and the verification knock is similar to the regularity judgment content of the peak in the time domain waveform and the detection knock described above. For details, please refer to the regularity judgment content of the peak in the time domain waveform and the detection knock described above, which will not be further elaborated here.

[0102] In another specific implementation, when the peak in the time domain waveform is inconsistent with the regularity of the detected knocking, it is necessary to further verify the route survey location point, which may specifically include:

[0103] When the peak in the time domain waveform is inconsistent with the regularity of the detection knocking, obtaining a verification peak in the time domain waveform; the verification peak is generated by the verification knocking acting on the route survey location point;

[0104] When the verification wave peak is consistent with the pattern of the verification knocking, it is confirmed that the route survey position point belongs to the optical cable routing point.

[0105] Further, after the step of confirming that the route survey location point belongs to an optical cable route point, the method may further include:

[0106] The frequency domain waveform of the candidate optical cable distance point is displayed; the frequency domain waveform reflects the frequency of the vibration or sound wave received by the candidate optical cable distance point.

[0107] When there is a characteristic frequency peak in the frequency domain waveform, the optical cable entity corresponding to the optical cable routing point is confirmed; the characteristic frequency peak is formed by vibrating the optical cable entity at the characteristic frequency. In actual detection, the same routing survey location point may contain multiple optical cables, and only one of them is the optical cable to be surveyed. However, it is difficult to determine which specific optical cable entity is the optical cable to be surveyed by only tapping the routing survey location point. Therefore, after determining the candidate optical cable distance point, the characteristic frequency vibration is applied to the optical cable entity respectively. If the corresponding characteristic frequency peak appears on the frequency domain waveform of the candidate optical cable distance point, it means that the optical cable entity currently receiving the characteristic frequency vibration is the optical cable to be surveyed. After determining the optical cable entity, it can facilitate the subsequent maintenance of the optical cable.

[0108] It is understandable that the main task of the optical cable census is to record the routing location point information of the optical cable. Recording the location point information as a dumb resource of the optical cable can better provide a basis for the subsequent optical cable maintenance work. Therefore, in this embodiment, after confirming that the routing census location point belongs to the optical cable routing point, it is also necessary to upload the data of the routing census location point for processing and analysis, which specifically includes:

[0109] Using the distance data corresponding to the candidate optical cable distance point as the detection distance of the route survey location point;

[0110] Obtaining the latitude and longitude data of the route survey location point;

[0111] The latitude and longitude data and the detection distance are uploaded to a server.

[0112] By uploading the latitude and longitude data of the route survey location point to the server, the route survey location point and the corresponding latitude and longitude data are associated and recorded in the database of the server, which is conducive to locating the route survey point on the map and facilitating the generation of optical cable routing lines after the subsequent completion of the optical cable routing survey.

[0113] In a specific implementation of this embodiment, the steps include:

[0114] Enter the vibration waveform page, which contains the "Fiber Real-time Waveform" and "Time Domain Waveform".

[0115] Perform the first trial tapping on the route survey location point, and locate the approximate tapping position range (i.e., optical cable distance range) of the route survey location point based on the raised peak of the curve in the "Fiber Real-time Waveform"; confirm the distance display interval of the horizontal axis of the "Fiber Real-time Waveform" curve based on the position range.

[0116] Adjust the distance display interval to the approximate range of the current tapping point, start the detection tapping, and tap the route survey location point multiple times within the countdown. The system will give a judgment result based on the current configuration and tapping situation.

[0117] Click the peak position determined by the system in the "Fiber Real-time Waveform" graph to view the time domain waveform of the selected position. Compare the vibration waveform displayed by the time domain waveform of the point with the number and time of tapping. If they are consistent, the result is correct. You can also tap again to see if the time domain waveform of the point has a peak response to further confirm whether it is the optical cable routing point.

[0118] After confirming that everything is correct, click the "Upload" button. A window for uploading data will pop up. After confirming that no correction is required, click "Upload".

[0119] Among them, in the process of clicking the peak position point determined by the system in the "Fiber Real-time Waveform" diagram, you can view all the knocking response result sets in advance, click the selection button, and select the corresponding peak position point result.

[0120] Example 2

[0121] Based on the same inventive concept as in Example 1, Figure 6 As shown, this embodiment provides an optical cable route survey system, and the survey system includes:

[0122] The waveform range acquisition module 11 is used to acquire a first convex wave peak in the optical fiber real-time waveform window, and confirm the optical cable distance range of the route survey location point according to the first convex wave peak; the first convex wave peak is generated by a first test tapping on the route survey location point;

[0123] Specifically, in this embodiment, before the step of obtaining the first convex crest, the method further includes:

[0124] Enter the vibration waveform page; the vibration waveform page includes the optical fiber real-time waveform window and the time domain waveform window.

[0125] It is understandable that in this embodiment, the survey of the optical cable route is mainly carried out by connecting the optical cable sonar or optical cable line analyzer and other detection equipment with phase-sensitive optical time domain reflectometer to the optical cable to be surveyed at the starting facility point of the survey, such as the optical cable room, optical cross-box, etc., to detect and analyze the vibration or sound waves received by the optical cable. Then, the corresponding vibration is applied to the intermediate facility point where the optical cable to be surveyed may pass, such as the optical cable well or the optical cable rack, and the distance between the position point where the vibration is applied and the survey starting facility point where the detection equipment is located is determined by the detection equipment, and the routing of the optical cable is determined by determining the position point and the corresponding optical cable distance.

[0126] Therefore, in this embodiment, the step of entering the vibration waveform page may specifically include:

[0127] Confirm the optical cables to be surveyed and the survey starting point;

[0128] Configure the host ID and device port corresponding to the optical cable to be inspected; after configuring the host ID and device port, the detection device can be connected to the corresponding device port, so that the detection device can receive the optical cable data of the optical cable to be inspected in real time, and generate a real-time vibration waveform according to the optical cable data;

[0129] Enter the vibration waveform page based on the host ID and the device port; the vibration waveform page is used to display the vibration waveform generated by the detection device according to the optical cable data of the optical cable to be surveyed, so after connecting the detection device to the device interface, the detection device can be accessed and the vibration waveform page can be entered according to the host ID and the device port.

[0130] Preferably, in this embodiment, the detection device can be accessed through mobile devices such as mobile phones and laptop computers, and the system of the detection device can be accessed through the mobile device, and the vibration waveform page can be displayed on the mobile device; wherein, the access connection between the mobile device and the detection device can be achieved through a wireless network such as a 4G / 5G network, so that in the subsequent process of the optical cable route census, the vibration condition of the optical cable to be surveyed can be checked in real time through the vibration waveform page.

[0131] It can be understood that the optical fiber real-time waveform window is mainly used to display the real-time waveform generated by the detection equipment, wherein the real-time waveform is generated by the detection equipment based on the real-time optical cable data of the optical cable to be surveyed, reflecting the overall real-time vibration condition of the optical cable to be surveyed; the time domain waveform window is mainly used to display the change of the vibration waveform of the corresponding position point on the optical cable to be surveyed over time.

[0132] Therefore, in order to clearly and quickly observe the vibration condition of the optical cable to be surveyed at the route survey position point, it is necessary to first determine the distance point range of the route survey position point on the optical cable to be surveyed, so the first test strike is applied at the route survey position point, and the first test strike acts on the optical cable to be surveyed. If the optical cable to be surveyed passes through the current route survey position point, the corresponding first raised wave peak can be observed at the corresponding cable distance point through the optical fiber real-time waveform window, and then the range contained in the wave peak of the first raised wave peak can be used as the cable distance range of the route survey position point on the optical cable to be surveyed.

[0133] An interval confirmation module 12 is used to confirm the distance display interval of the optical fiber real-time waveform window based on the optical cable distance range;

[0134] Specifically, the distance display interval of the optical fiber real-time waveform window is adjusted according to the optical cable distance range so that the route survey point falls within the distance display interval. If the optical cable distance range accounts for a low proportion in the current distance display interval, for example, the proportion is lower than the set proportion, the distance display interval of the optical fiber real-time waveform window can be adjusted based on the optical cable distance range, for example, 100 meters before the optical cable distance range and 300 meters after the optical cable distance range are used as the new distance display interval. If the optical cable distance range accounts for a moderate proportion in the current distance display interval, for example, the proportion is within the set range, the current distance display interval can be maintained without change.

[0135] In one example, the step of confirming the distance display interval of the optical fiber real-time waveform window based on the optical cable distance range includes:

[0136] Taking the optical cable distance range as a base point, narrow the distance display interval of the optical fiber real-time waveform window; the distance display interval represents the distance range of the real-time vibration waveform of the optical cable to be surveyed displayed by the optical fiber real-time waveform window. For example, if the distance display interval is 0-100m, it means that the optical fiber real-time waveform window displays the real-time vibration waveform of the optical cable to be surveyed within the range of 0-100m.

[0137] As described above, the optical fiber real-time waveform window displays the overall real-time vibration of the optical cable to be inspected, so in the initial case, the distance display interval is the length of the entire optical cable to be inspected or the preset optical cable length, so that the first raised peak accounts for a small proportion in the optical fiber real-time waveform window, which is not convenient for the subsequent observation of the corresponding knocking waveform; therefore, it is necessary to narrow the distance display interval of the optical fiber real-time waveform window so that the distance display interval of the optical fiber real-time waveform window can roughly match the first raised peak, so that the vibration peak generated by the subsequent knocking can also better fall into the distance display interval for observation.

[0138] Preferably, when a second raised wave peak is detected within the distance display interval, it is confirmed that the route survey location point is within the distance display interval; the second raised wave peak is generated by a second test tapping on the route survey location point.

[0139] As described above, due to the limited number of times and impact time of the first trial tap, the distance display interval obtained based on the first raised wave peak is not completely accurate. Therefore, the second trial tap can be applied to observe whether the second raised wave peak formed by the second trial tap can match the confirmed distance display interval to ensure that the route survey point falls within the distance display interval.

[0140] It should be noted that if the second raised peak still does not match the distance display interval, the distance display interval can be adjusted according to the second raised peak, moved forward, backward, enlarged or reduced as appropriate, and a third trial knock can be applied to form a corresponding third raised peak for observation.

[0141] The peak extraction module 13 is used to obtain the detection peak in the distance display interval; the detection peak is generated by the detection knocking acting on the route survey location point; the detection knocking is multiple knocking within a preset time;

[0142] It is understandable that since the route survey is usually conducted outdoors and may be conducted in a noisy environment, during the route survey, the optical cable to be surveyed will not only be affected by the knocking during the route survey, but will also be affected by vibrations or noises in various environments, which will interfere with the vibration waveform; so in this embodiment, the detection knocking is multiple knockings within a preset time, and the number of detection peaks within the corresponding preset time can be compared with the number of knockings to confirm the location point or location range of the optical cable to be surveyed with the detection knocking, reduce the interference of external environmental vibration and noise, and improve the accuracy of detection. After the detection knocking and the corresponding comparison confirmation, the detection peak is displayed in the distance display interval, or the distance range corresponding to the detection peak is displayed.

[0143] A time domain display module 14, used to confirm a candidate optical cable distance point in the detection peak and display a time domain waveform of the candidate optical cable distance point;

[0144] Specifically, the detection peak may correspond to a position point or a distance range. Therefore, a position point with the maximum vibration intensity or a vibration intensity exceeding a set threshold is obtained in the detection peak as the candidate optical cable position point. After the candidate optical cable position point is obtained, the time domain waveform of the candidate optical cable position point can be obtained and displayed through the time domain waveform window.

[0145] Among them, in order to better realize the display of the time domain waveform, before the step of confirming the candidate optical cable distance point in the detection peak and displaying the time domain waveform of the candidate optical cable distance point, it is necessary to obtain the time domain data used to form the time domain waveform, which may specifically include:

[0146] Within the preset time, time domain data of multiple optical cable distance points within a sliding distance interval are collected at preset intervals; the time domain data are used to generate corresponding time domain waveforms; wherein the sliding distance interval is determined based on the collection start distance or the distance of the previous optical cable routing point.

[0147] It can be understood that the sliding distance interval is a certain distance range displayed in the optical fiber real-time waveform window starting from the previous census route position point. As the route census proceeds, the sliding distance interval will continue to "slide" backward in the optical fiber real-time waveform window, ensuring that the vibration waveform generated by tapping the current census route position point can be well observed from the optical fiber real-time waveform window.

[0148] Exemplarily, assuming that the current location is the first surveyed route location point, the sliding distance interval can be 0-10km, so that the optical fiber real-time waveform window can display the real-time vibration waveform within the 0-10km optical cable range of the optical cable to be surveyed; when the survey of the first surveyed route location point is completed, and the corresponding distance of the first surveyed route location point on the optical cable to be surveyed is 1km, the sliding distance interval can be 1km-11km. That is, the sliding distance interval slides backward as the survey proceeds, so that the optical fiber real-time waveform window can better display the vibration waveform of the current surveyed route location point.

[0149] The vibration analysis module 15 is used to confirm that the route survey location point belongs to the optical cable route point when the peak in the time domain waveform is consistent with the law of the detected knocking.

[0150] As described above, the time domain waveform acquired and displayed by the time domain waveform window reflects the change of the vibration waveform of the candidate optical cable distance point over time. Then, if the candidate optical cable distance point corresponds to the route census position point, the number of knocks of the detection vibration applied to the route census position point within the preset time is matched with the number of peaks appearing in the time domain waveform of the candidate optical cable distance point;

[0151] Therefore, in this embodiment, when the peak in the time domain waveform is consistent with the rule of the detected knocking, the step of confirming that the route survey location point belongs to the optical cable route point may specifically include:

[0152] Obtaining the number of peaks of the time domain waveform within the preset time;

[0153] When the number of wave peaks is consistent with the number of detection knocks, it is confirmed that the route survey location point belongs to the optical cable routing point.

[0154] In a specific implementation, when the peak in the time domain waveform is consistent with the rule of the detection knocking, after the step of confirming that the route survey location point belongs to the optical cable route point, it is also necessary to verify the route survey location point, which may specifically include:

[0155] Obtaining a verification wave peak in the time domain waveform; the verification wave peak is generated by a verification tapping on the route survey location point;

[0156] When the verification wave peak is consistent with the regularity of the verification tapping, the verification of the route survey position point is completed.

[0157] The regularity judgment content of the verification peak and the verification knock is similar to the regularity judgment content of the peak in the time domain waveform and the detection knock described above. For details, please refer to the regularity judgment content of the peak in the time domain waveform and the detection knock described above, which will not be further elaborated here.

[0158] In another specific implementation, when the peak in the time domain waveform is inconsistent with the regularity of the detected knocking, it is necessary to further verify the route survey location point, which may specifically include:

[0159] When the peak in the time domain waveform is inconsistent with the regularity of the detection knocking, obtaining a verification peak in the time domain waveform; the verification peak is generated by the verification knocking acting on the route survey location point;

[0160] When the verification wave peak is consistent with the pattern of the verification knocking, it is confirmed that the route survey position point belongs to the optical cable routing point.

[0161] Further, after the step of confirming that the route survey location point belongs to an optical cable route point, the method may further include:

[0162] The frequency domain waveform of the candidate optical cable distance point is displayed; the frequency domain waveform reflects the frequency of the vibration or sound wave received by the candidate optical cable distance point.

[0163] When there is a characteristic frequency peak in the frequency domain waveform, the optical cable entity corresponding to the optical cable routing point is confirmed; the characteristic frequency peak is formed by vibrating the optical cable entity at the characteristic frequency. In actual detection, the same routing survey location point may contain multiple optical cables, and only one of them is the optical cable to be surveyed. However, it is difficult to determine which specific optical cable entity is the optical cable to be surveyed by only tapping the routing survey location point. Therefore, after determining the candidate optical cable distance point, the characteristic frequency vibration is applied to the optical cable entity respectively. If the corresponding characteristic frequency peak appears on the frequency domain waveform of the candidate optical cable distance point, it means that the optical cable entity currently receiving the characteristic frequency vibration is the optical cable to be surveyed. After determining the optical cable entity, it can facilitate the subsequent maintenance of the optical cable.

[0164] It is understandable that the main task of the optical cable census is to record the routing location point information of the optical cable. Recording the location point information as a dumb resource of the optical cable can better provide a basis for the subsequent optical cable maintenance work. Therefore, in this embodiment, after confirming that the routing census location point belongs to the optical cable routing point, it is also necessary to upload the data of the routing census location point for processing and analysis, which specifically includes:

[0165] Using the distance data corresponding to the candidate optical cable distance point as the detection distance of the route survey location point;

[0166] Obtaining the latitude and longitude data of the route survey location point;

[0167] The latitude and longitude data and the detection distance are uploaded to a server.

[0168] By uploading the latitude and longitude data of the route survey location point to the server, the route survey location point and the corresponding latitude and longitude data are associated and recorded in the database of the server, which is conducive to locating the route survey point on the map and facilitating the generation of optical cable routing lines after the subsequent completion of the optical cable routing survey.

[0169] In a specific implementation of this embodiment, the steps include:

[0170] Enter the vibration waveform page, which contains the "Fiber Real-time Waveform" and "Time Domain Waveform".

[0171] Perform the first trial tapping on the route survey location point, and locate the approximate tapping position range (i.e., optical cable distance range) of the route survey location point based on the raised peak of the curve in the "Fiber Real-time Waveform"; confirm the distance display interval of the horizontal axis of the "Fiber Real-time Waveform" curve based on the position range.

[0172] Adjust the distance display interval to the approximate range of the current tapping point, start the detection tapping, and tap the route survey location point multiple times within the countdown. The system will give a judgment result based on the current configuration and tapping situation.

[0173] Click the peak position determined by the system in the "Fiber Real-time Waveform" graph to view the time domain waveform of the selected position. Compare the vibration waveform displayed by the time domain waveform of the point with the number and time of tapping. If they are consistent, the result is correct. You can also tap again to see if the time domain waveform of the point has a peak response to further confirm whether it is the optical cable routing point.

[0174] After confirming that everything is correct, click the "Upload" button. A window for uploading data will pop up. After confirming that no correction is required, click "Upload".

[0175] Among them, in the process of clicking the peak position point determined by the system in the "Fiber Real-time Waveform" diagram, you can view all the knocking response result sets in advance, click the selection button, and select the corresponding peak position point result.
