At least at this stage, communication optical cables are gradually developing towards maturity, functionality and diversification. As their functions become increasingly powerful, their application in daily communication networks has become more extensive.

[0003] During the construction of buried communication optical cables, due to problems such as non-standard construction and lack of construction records, it is difficult to determine the actual direction of the optical cable, resulting in the inability to find the axial center position of the optical cable during later maintenance. Rash excavation without knowing the specific location of the optical cable not only wastes a lot of manpower, material resources, financial resources and time, but also damages the optical cable and increases communication losses.

[0020] In one embodiment of the present application, the second straight line passes through an extension line of a line connecting a ground position corresponding to the target position and a ground position corresponding to the position of the positioning device, and is a ground position at a preset distance from the ground position corresponding to the target position.

[0038] like Figure 1As shown, a positioning device 100 for optical cable coiling in the present application is schematically shown, including a narrow line width light source 101, a high-precision acousto-optic modulator 102, a pulse amplifier 103, a circulator 104, a fiber amplifier 105, a fiber filter 106, a photodetector 107, a bandpass filter 108, a host computer 109, and a buried optical cable 110. The narrow line width light source 101 is connected to the high-precision acousto-optic modulator 102, the high-precision acousto-optic modulator 102 is connected to the pulse amplifier 103, the pulse amplifier 103, the fiber amplifier 105 and the buried optical cable 110 are connected together through the circulator 104, the fiber amplifier 105 is connected to the fiber filter 106, the fiber filter 106 is connected to the photodetector 107, the photodetector 107 is connected to the bandpass filter 108, and the bandpass filter 108 is connected to the host computer 109.

[0039] The narrow linewidth light source 101 emits a continuous optical signal of a preset wavelength, for example, a continuous optical signal of a wavelength of 1550 nm, so that the continuous optical signal enters the high-precision acousto-optic modulator 102, and modulates an optical pulse signal of a preset pulse width through the high-precision acousto-optic modulator 102. For example, a 20 ns pulse width optical pulse signal is modulated through the high-precision acousto-optic modulator 102. The optical pulse signal enters the pulse amplifier 103 through the high-precision acousto-optic modulator 102 for amplification. The amplified optical pulse signal enters the buried optical cable 110 through the circulator 104. After the buried optical cable 110 receives the optical pulse signal, the buried optical cable 110 0 will cause Rayleigh scattering, wherein the Rayleigh scattered light signal scattered toward the rear can return to the circulator 104 through the buried optical cable 110 and enter the optical fiber amplifier 105 for amplification, the amplified Rayleigh scattered light signal enters the optical fiber filter 106 to filter out the optical noise, the Rayleigh scattered light signal after the noise is filtered out enters the photodetector 107 to be converted into an electrical analog signal, the electrical analog signal enters the bandpass filter 108 to filter out the noise and interference signal, the filtered electrical analog signal is transmitted to the host computer 109 for collection, normalization algorithm and other processing, and the result is displayed on the screen in the form of a vibration waveform.

[0040] like Figure 1 As shown, the circulator 104 in the optical cable coiling positioning device 100 is connected to the buried optical cable 110, that is, it is connected to one end of the buried optical cable 110. When the ground above the buried optical cable 110 is struck, the vibration generated by striking the ground can be propagated along the soil, and the propagated vibration will affect the buried optical cable 110, so that the buried optical cable 110 generates a vibration signal. The vibration signal of the buried optical cable 110 can be propagated based on the Rayli scattered light signal, and the optical cable coiling positioning device 100 can convert the obtained optical signal into an electrical analog signal, thereby obtaining a waveform corresponding to the vibration signal of the buried optical cable 110.

[0041] like Figure 2As shown, a flow chart of a method for determining the direction of an optical cable in the present application is schematically shown, such as Figure 2 As shown, the following steps are included:

[0042] Step 201, determining a first sampling point according to the position of a positioning device;

[0043] Step 202, determining a predicted initial position of the optical cable according to the waveform of the first sampling point;

[0044] Step 203, determining a plurality of second sampling points on a first straight line perpendicular to a line connecting a ground position corresponding to the predicted initial position and a ground position corresponding to the position of the positioning device, wherein the first straight line passes through the predicted initial position;

[0045] Step 204, determining the target position of the optical cable according to the waveform of the second sampling point;

[0046] Step 205, when the ground distance between the ground position corresponding to the target position and the ground position corresponding to the position of the positioning device is less than a preset threshold, determine a plurality of third sampling points on a second straight line perpendicular to an extension line of a line connecting the ground position corresponding to the target position and the ground position corresponding to the positioning device;

[0047] Step 206, determining a new target position of the optical cable according to the waveform of the third sampling point;

[0048] Step 207, when the ground distance between the ground position corresponding to the new target position and the ground position corresponding to the position of the positioning device is less than a preset threshold, determine a plurality of third sampling points on a third straight line perpendicular to an extension line of a line connecting the ground positions of the two latest target positions;

[0049] Step 208, returning to the step of determining a new target position of the optical cable according to the waveform of the third sampling point, until the ground distance between the ground position corresponding to the new target position and the ground position corresponding to the position of the positioning device is greater than or equal to a preset threshold;

[0050] Step 209, determining the direction of the optical cable according to the connection lines obtained at all target positions.

[0051] The operator can connect the positioning device to the buried optical cable and set multiple sampling points in the area to be detected. In order to obtain the vibration signal of the sampling point more clearly, the operator can place an iron plate on the ground in the area to be detected and knock on the iron plate above the sampling point to obtain the vibration signal corresponding to the sampling point and the waveform of the vibration signal.

[0052] The processor can sequentially obtain the vibration signal of the first sampling point, and obtain the waveform corresponding to the vibration signal, and determine the predicted initial position of the optical cable through the waveform of the first sampling point. After the processor determines the predicted initial position of the optical cable according to the vibration signal of the first sampling point, it can determine the connection line between the ground position corresponding to the predicted initial position of the optical cable and the ground position corresponding to the positioning device. A first straight line perpendicular to the connection line is determined at the ground position corresponding to the predicted initial position, and multiple second sampling points are determined on the determined first straight line.

[0053] The processor can obtain the vibration signal of the second sampling point, and determine the waveform corresponding to the second sampling point based on the vibration signal. The target position of the optical cable can be determined based on the waveform of the second sampling point. The processor can determine the ground position corresponding to the target position of the optical cable, and determine the ground distance between the ground position corresponding to the target position of the optical cable and the ground position corresponding to the position of the positioning device. When the ground distance is less than a preset threshold set by the processor, the processor can determine the line connecting the ground position of the target position and the ground position of the positioning device, and determine multiple third sampling points on a second straight line perpendicular to the extension line of the connecting line.

[0054] The processor can sequentially obtain the vibration signal of the third sampling point, and determine the waveform of the third sampling point according to the vibration signal, and the processor can determine the new target position of the optical cable according to the waveform of the third sampling point. After the processor determines the new target position of the optical cable, the processor can determine the ground distance between the ground position corresponding to the new target position and the ground position corresponding to the position of the positioning device, and determine whether the ground distance between the ground position corresponding to the target position and the ground position corresponding to the position of the positioning device is less than a preset threshold set by the processor. In the case of determining that the ground distance between the two is less than the preset threshold, the processor can determine the connection line of the ground positions of the two latest target positions, and determine multiple third sampling points on the third straight line perpendicular to the extension line of the connection line. The processor can determine the new target position of the optical cable again according to the waveform of the vibration signal of the multiple third sampling points determined, and determine whether the ground distance between the ground position corresponding to the new target position of the optical cable and the ground position corresponding to the position of the positioning device is less than the preset threshold set by the processor. If the ground distance between the ground position corresponding to the new target position of the optical cable and the ground position corresponding to the position of the positioning device is less than the preset threshold set by the processor, the processor can determine the third straight line perpendicular to the extension line of the connection line again according to the connection line of the ground positions of the two latest target positions, and determine multiple third sampling points according to the third straight line. Until the ground distance between the ground position corresponding to the new target position of the optical cable and the ground position corresponding to the position of the positioning device is greater than or equal to a preset threshold set by the processor, the processor may stop determining the third straight line and the third sampling point.

[0055] The processor may determine the connection lines between all the target positions according to all the determined target positions, and determine the direction of the optical cable according to the connection lines between all the obtained target positions.

[0056] In one embodiment, determining the predicted initial position of the optical cable based on the waveform of the first sampling point includes: tapping each first sampling point in turn at a first preset frequency to obtain a first vibration signal of each first sampling point; when the frequency of the first vibration signal meets the first preset frequency and the waveform of the first vibration signal includes a preset waveform, determining the position corresponding to the central peak of the preset waveform as the predicted initial position.

[0057] The processor can set a first preset frequency to tap each first sampling point. For example, the processor can set the first preset frequency to an interval of 1 second, tap once per second, and tap 5 times in total. In order to distinguish other interfering vibration signals, the processor can set the preset frequency of the vibration signal to a tap feature that appears once every one second, for a total of five times. Therefore, when the frequency of the vibration signal obtained by the processor meets the preset frequency, it is determined that the obtained vibration signal is a valid vibration signal, thereby obtaining the waveform of the vibration signal. After obtaining the waveform of the vibration signal of the first sampling point, the processor can analyze the waveform of the obtained vibration signal. In the case where the waveform of the first vibration signal includes a preset waveform, the processor can determine the position corresponding to the central peak of the preset waveform as the predicted initial position. The preset waveform can be a waveform corresponding to the optical cable.

[0058] In one embodiment, the optical cable mileage at the predicted initial position is determined according to the position of the positioning device and the predicted initial position; and the optical cable mileage is determined as the optical cable mileage at the starting point of the optical cable whose direction is to be confirmed.

[0059] After determining the predicted initial position of the optical cable, the processor can determine the position of the optical cable where the positioning device is located and the predicted initial position of the optical cable, and determine the cable mileage at the predicted initial position of the optical cable, wherein the cable mileage is the distance between the position of the optical cable where the positioning device is located and the predicted initial position of the optical cable. After the processor determines the cable mileage at the predicted initial position, the cable mileage at the predicted initial position can be determined as the cable mileage of the starting point of the direction of the optical cable to be confirmed.

[0060] For example, assuming that the processor sequentially acquires a first vibration signal at a first sampling point and determines a waveform of the first vibration signal at the first sampling point, after determining that the frequency of the acquired first vibration signal meets a preset frequency set by the processor, and the waveform of the first vibration signal includes a preset waveform, such as Figure 3 As shown, assuming Figure 3 The waveform shown is the waveform of the first vibration signal at the first sampling point. The processor determines that the waveform of the first vibration signal includes the following Figure 3 If the preset waveform a is shown, the processor can determine the position of the optical cable corresponding to the central peak of the preset waveform a, and determine the position of the optical cable corresponding to the central peak of the preset waveform a as the preset initial position. At the same time, assuming that the origin is the position of the optical cable where the positioning device is located, the processor can determine the optical cable mileage M between the position of the optical cable corresponding to the preset initial position and the position of the optical cable where the positioning device is located. At this time, the processor can determine the optical cable mileage M as the optical cable mileage M at the starting point of the direction of the optical cable to be determined. For example, assuming that the optical cable mileage of the initial position is predicted to be 500 meters, the optical cable mileage at the starting point of the direction of the optical cable to be determined is 500 meters.

[0061] In one embodiment, determining the target position of the optical cable based on the waveform of the second sampling point includes: tapping each second sampling point in turn at a second preset frequency to obtain a second vibration signal of each second sampling point; and analyzing the waveform of each second vibration signal to determine the target position of the optical cable.

[0062] After the processor determines multiple second sampling points on the first straight line, it can tap each second sampling point in turn according to the second preset frequency, so as to obtain a second vibration signal of each second sampling point. For example, the processor can set the second preset frequency to tap the ground three times every three seconds. After the processor obtains the second vibration signal of each second sampling point, it can obtain the waveform of the second vibration signal, analyze the waveform of each second vibration signal, and thus determine the target position through the waveform of the second vibration signal.

[0063] In one embodiment, analyzing the waveform of each second vibration signal to determine the target position of the optical cable includes: obtaining the waveform of the vibration signal of each second sampling point, and determining the average value of the peak amplitude of the waveform of each second sampling point; and determining the position corresponding to the central peak of the waveform with the highest average value of the peak amplitude among the waveforms of the vibration signals of all the second sampling points as the target position of the optical cable.

[0064] The processor can obtain the vibration signal of each second sampling point, obtain the waveform of the vibration signal of each second sampling point, and obtain the average value of the peak amplitude of the waveform of each second sampling point. For example, suppose the second preset frequency set by the processor is once every three seconds, and the ground is hit three times. The processor can determine the average value of the peak amplitude of the waveform of the vibration signal obtained by hitting the ground three times. The processor can determine the average value of the peak amplitude of the waveform of the vibration signal of each second sampling point. Determine the waveform with the highest average value of the peak amplitude among the waveforms of the vibration signals of all second sampling points, and determine the position corresponding to the central peak of the waveform with the highest average value of the peak amplitude as the target position of the optical cable.

[0065] In one embodiment, the second straight line passes through a ground position corresponding to the target position and a ground position corresponding to the position of the positioning device, on an extension line of a line connecting the ground position corresponding to the target position and the ground position corresponding to the position of the positioning device, and is at a ground position at a preset distance from the ground position corresponding to the target position.

[0066] After the processor determines the target position of the optical cable, a second straight line can be determined based on the ground position corresponding to the target position and the ground position corresponding to the positioning device. The processor can determine the line between the ground position corresponding to the target position and the ground position corresponding to the positioning device, and determine multiple third sampling points on the second straight line perpendicular to the extension line of the line. Among them, the processor can set a preset distance, and determine the position at the preset distance from the target position on the extension line of the line between the ground position corresponding to the target position and the ground position corresponding to the positioning device, so that the second straight line passes through the position at the preset distance from the target position. For example, assuming that the processor sets the preset distance to 10 meters, a second straight line is set at a position 10 meters away from the target position on the extension line of the line between the ground position corresponding to the target position and the ground position corresponding to the position of the positioning device, and the second straight line is perpendicular to the extension line of the line. Multiple third sampling points are set on the second straight line.

[0067] In one embodiment, determining the new target position of the optical cable based on the waveform of the third sampling point includes: tapping each third sampling point in turn at a second preset frequency to obtain a third vibration signal of each third sampling point; obtaining the waveform of the vibration signal of each third sampling point, and determining the average value of the peak amplitude of the waveform of each third sampling point; and determining the position corresponding to the central peak of the waveform with the highest average value of the peak amplitude among the waveforms of the vibration signals of all the third sampling points as the new target position of the optical cable.

[0068] After the processor determines a plurality of third sampling points on the second straight line, it can tap each third sampling point in turn according to the second preset frequency, so as to obtain a third vibration signal of each third sampling point. For example, the processor can set the second preset frequency to once every three seconds, and tap the ground three times. After the processor obtains the third vibration signal of each third sampling point, it can obtain the waveform of the third vibration signal of each third sampling point, and obtain the average value of the peak amplitude of the waveform of each third sampling point. For example, assuming that the second preset frequency set by the processor is once every three seconds, and tap the ground three times. The processor can determine the average value of the peak amplitude of the waveform of the third vibration signal obtained by tapping the ground three times. The processor can determine the average value of the peak amplitude of the waveform of the third vibration signal of each third sampling point. And determine the waveform with the highest average value of the peak amplitude among the waveforms of the vibration signals of all third sampling points, and determine the position corresponding to the central peak of the waveform with the highest average value of the peak amplitude as the new target position of the optical cable.

[0069] In one embodiment, the third straight line passes through a ground position at a preset distance from the new target position on an extension line of a line connecting the ground positions of the two latest target positions.

[0070] After the processor determines the new target position of the optical cable, it can determine whether the ground distance between the ground position corresponding to the new target position and the ground position corresponding to the position of the positioning device is less than a preset threshold set by the processor. When it is determined that the ground distance between the ground position corresponding to the new target position and the ground position corresponding to the position of the positioning device is less than the preset threshold, the processor can determine the connection line of the ground positions of the two latest target positions, and determine multiple third sampling points on the third straight line perpendicular to the extension line of the connection line. Among them, the processor can set a preset distance, and determine the position at the preset distance from the new target position on the extension line of the connection line of the ground positions corresponding to the two latest target positions, so that the third straight line passes through the position at the preset distance from the new target position. For example, assuming that the processor sets the preset distance to 10 meters, the two latest target positions are the first target position and the second target position, respectively, wherein the first target position is earlier than the second target position. On the extension line of the connection line between the ground positions corresponding to the two latest target positions, a third straight line is set at a position 10 meters away from the second target position, and the third straight line is perpendicular to the extension line of the connection line. Multiple third sampling points are set on the third straight line.

[0071] In one embodiment, the processor may determine an average value of the peak amplitude of each target position, and use the average value of the peak amplitude of each target position as the buried depth of the optical cable corresponding to each target position.

[0072] In one embodiment, a processor is provided, configured to execute the method for determining the direction of an optical cable according to any one of the above items.

[0073] The circulator in the positioning device of the optical cable coil can be connected to the buried optical cable, and obtain the vibration signal of the buried optical cable, and determine the corresponding waveform according to the received vibration signal. Multiple sampling points can be set on the ground above the buried optical cable, and each sampling point can be tapped so that the processor can obtain the vibration signal of the buried optical cable at each sampling point. Since there may be other interfering vibration signals, it is necessary to obtain the waveform of the vibration signal when the frequency of the vibration signal meets the preset frequency. The preset frequency of the vibration signal can be set to be consistent with the frequency of tapping the sampling point.

[0074] The operator can connect the positioning device to the buried optical cable and set multiple first sampling points in the area to be detected. In order to more clearly obtain the vibration signal of the first sampling point, the operator can place an iron plate on the ground of the area to be detected and knock on the iron plate above the first sampling point to obtain the first vibration signal corresponding to the first sampling point and the waveform of the first vibration signal.

[0075] The processor can set a first preset frequency to tap each first sampling point. For example, the processor can set the first preset frequency to an interval of 1 second, tap once per second, and tap 5 times in total. In order to distinguish other interfering vibration signals, the processor can set the preset frequency of the vibration signal to a tap feature that appears once every one second, for a total of five times. Therefore, when the frequency of the vibration signal obtained by the processor meets the preset frequency, it is determined that the obtained vibration signal is a valid vibration signal, thereby obtaining the waveform of the vibration signal. After obtaining the waveform of the vibration signal of the first sampling point, the processor can analyze the waveform of the obtained vibration signal. In the case where the waveform of the first vibration signal includes a preset waveform, the processor can determine the position corresponding to the central peak of the preset waveform as the predicted initial position. The preset waveform can be a waveform corresponding to the optical cable.

[0076] After determining the predicted initial position of the optical cable, the processor can determine the position of the optical cable where the positioning device is located and the predicted initial position of the optical cable, and determine the cable mileage at the predicted initial position of the optical cable, wherein the cable mileage is the distance between the position of the optical cable where the positioning device is located and the predicted initial position of the optical cable. After the processor determines the cable mileage at the predicted initial position, the cable mileage at the predicted initial position can be determined as the cable mileage at the starting point of the direction of the optical cable to be confirmed.

[0077] For example, assuming that the processor sequentially acquires a first vibration signal at a first sampling point and determines a waveform of the first vibration signal at the first sampling point, after determining that the frequency of the acquired first vibration signal meets a preset frequency set by the processor, and the waveform of the first vibration signal includes a preset waveform, such as Figure 3 As shown, assuming Figure 3 The waveform shown is the waveform of the first vibration signal at the first sampling point. The processor determines that the waveform of the first vibration signal includes the following Figure 3If the preset waveform a is shown, the processor can determine the position of the optical cable corresponding to the central peak of the preset waveform a, and determine the position of the optical cable corresponding to the central peak of the preset waveform a as the preset initial position. At the same time, assuming that the origin is the position of the optical cable where the positioning device is located, the processor can determine the optical cable mileage M between the position of the optical cable corresponding to the preset initial position and the position of the optical cable where the positioning device is located. At this time, the processor can determine the optical cable mileage M as the optical cable mileage M at the starting point of the direction of the optical cable to be determined. At this time, the processor can determine the optical cable mileage as the optical cable mileage at the starting point of the direction of the optical cable to be determined. For example, assuming that the optical cable mileage of the initial position is predicted to be 500 meters, the optical cable mileage at the starting point of the direction of the optical cable to be determined is 500 meters.

[0078] After the processor determines the predicted initial position of the optical cable according to the vibration signal of the first sampling point, a line between the ground position corresponding to the predicted initial position of the optical cable and the ground position corresponding to the positioning device can be determined, and a first straight line perpendicular to the line is determined at the ground position corresponding to the predicted initial position, and a plurality of second sampling points are determined on the determined first straight line.

[0079] After the processor determines a plurality of second sampling points on the first straight line, the operator can sequentially tap each second sampling point according to the second preset frequency, and the processor can receive the vibration signal of the sampling point. When the vibration signal obtained by the processor is consistent with the second preset frequency, the processor can determine that the vibration signal is the second vibration signal of the second sampling point. For example, the processor can set the second preset frequency to once every three seconds and tap the ground three times. After the processor obtains the second vibration signal of each second sampling point, it can obtain the waveform of the second vibration signal and obtain the average value of the peak amplitude of the waveform of each second sampling point. For example, assuming that the second preset frequency set by the processor is once every three seconds and taps the ground three times. The processor can determine the average value of the peak amplitude of the waveform of the vibration signal obtained by tapping the ground three times. The processor can determine the average value of the peak amplitude of the waveform of the vibration signal of each second sampling point. Determine the waveform with the highest average value of the peak amplitude among the waveforms of the vibration signals of all the second sampling points, and determine the position corresponding to the central peak of the waveform with the highest average value of the peak amplitude as the target position of the optical cable. In other words, the position corresponding to the central peak of the waveform with the highest average value of the peak amplitude is the buried position of the optical cable.

[0080] After the processor determines the target position of the optical cable by acquiring the waveform of the vibration signal of the second sampling point, the processor can determine the ground position corresponding to the target position of the optical cable, and determine the ground distance between the ground position corresponding to the target position of the optical cable and the ground position corresponding to the position of the positioning device, and judge whether it is less than the preset threshold set by the processor. The preset threshold set by the processor can be determined according to the range of the optical cable whose direction is to be determined determined by the operator. In the case where the processor determines that the ground distance between the ground positions corresponding to the position of the positioning device is less than the preset threshold set by the processor, the processor can determine the connection line between the ground position corresponding to the target position and the ground position corresponding to the positioning device, and determine multiple third sampling points on the second straight line perpendicular to the extension line of the connection line. Among them, the processor can set a preset distance, determine the position at the preset distance from the target position on the extension line of the connection line between the ground position corresponding to the target position and the ground position corresponding to the positioning device, and make the second straight line pass through the position at the preset distance from the target position. For example, assuming that the processor sets the preset distance to 10 meters, a second straight line is set at a position 10 meters away from the target position on the extension line of the connection line between the ground position corresponding to the target position and the ground position corresponding to the position of the positioning device, and the second straight line is perpendicular to the extension line of the connection line. Multiple third sampling points are set on the second straight line.

[0081] After the processor determines a plurality of third sampling points on the second straight line, it can tap each third sampling point in turn according to the second preset frequency, so as to obtain a third vibration signal of each third sampling point. For example, the processor can set the second preset frequency to once every three seconds, and tap the ground three times. After the processor obtains the third vibration signal of each third sampling point, it can obtain the waveform of the third vibration signal of each third sampling point, and obtain the average value of the peak amplitude of the waveform of each third sampling point. For example, assuming that the second preset frequency set by the processor is once every three seconds, and tap the ground three times. The processor can determine the average value of the peak amplitude of the waveform of the third vibration signal obtained by tapping the ground three times. The processor can determine the average value of the peak amplitude of the waveform of the third vibration signal of each third sampling point. And determine the waveform with the highest average value of the peak amplitude among the waveforms of the vibration signals of all third sampling points, and determine the position corresponding to the central peak of the waveform with the highest average value of the peak amplitude as the new target position of the optical cable.

[0082] For example, Figure 4As shown, the optical cable is buried in the soil. In order to determine the specific position of the optical cable in the soil, after the processor determines the target position of the optical cable through the second sampling point, it can determine the third straight line according to the target position and the ground distance of the positioning device, and set multiple third sampling points on the ground. The third sampling points can be set to be 2 meters apart. For each third sampling point, the ground can be knocked by a knocking device to determine the third vibration signal of each third sampling point. The processor can set the knocking frequency of the knocking device to once every three seconds, and knock the ground 3 times. After the processor obtains the third vibration signal of each third sampling point, it can obtain the waveform of the third vibration signal of each third sampling point, and obtain the average value of the peak amplitude of the waveform of each third sampling point. The processor can determine the waveform with the highest average value of the peak amplitude in the waveforms of the third sampling points as the target waveform, and determine the position corresponding to the central peak of the target waveform as the new target position of the optical cable. That is, the buried position of the optical cable. As shown Figure 4 As shown, the position corresponding to the central peak of the target waveform is the position of the optical cable buried in the soil.

[0083] In one embodiment, Figure 5 As shown, through Figure 4 After the target waveform and the location of the optical cable in the soil are determined by the method shown, the processor can identify the waveform at the sampling point, such as Figure 5 As shown, when the interval distance between the third sampling points is the same, but the waveform on the left side of the target waveform is significantly lower than the waveform on the right side, the processor can determine that there are facilities such as oil and gas pipelines on the left side of the optical cable, which affects the density of the soil, thereby obtaining a waveform lower than the third sampling point on the right side where there are no facilities underground.

[0084] After the processor determines the new target position of the optical cable, the processor can determine the ground distance between the ground position corresponding to the new target position and the ground position corresponding to the position of the positioning device, and determine whether the ground distance between the ground position corresponding to the target position and the ground position corresponding to the position of the positioning device is less than a preset threshold set by the processor. When it is determined that the ground distance between the two is less than the preset threshold, the processor can determine the line connecting the ground positions of the two latest target positions, and determine multiple third sampling points on a third straight line perpendicular to the extension line of the line. Among them, the processor can set a preset distance, and determine the position at the preset distance from the new target position on the extension line of the line connecting the ground positions corresponding to the two latest target positions, so that the third straight line passes through the position at the preset distance from the new target position. For example, assuming that the processor sets the preset distance to 10 meters, the two latest target positions are the first target position and the second target position, respectively, wherein the first target position is earlier than the second target position. On the extension line of the line between the ground positions corresponding to the two latest target positions, a third straight line is set at a position 10 meters away from the second target position, and the third straight line is perpendicular to the extension line of the line. Multiple third sampling points are set on the third straight line.

[0085] The processor can determine the new target position of the optical cable again based on the waveform of the vibration signal of the determined multiple third sampling points, and determine whether the ground distance between the ground position corresponding to the new target position of the optical cable and the ground position corresponding to the position of the positioning device is less than the preset threshold set by the processor. If the ground distance between the ground position corresponding to the new target position of the optical cable and the ground position corresponding to the position of the positioning device is less than the preset threshold set by the processor, a third straight line perpendicular to the extension line of the connecting line of the two latest target positions is determined again, and multiple third sampling points are determined based on the third straight line. Until the ground distance between the ground position corresponding to the determined new target position of the optical cable and the ground position corresponding to the position of the positioning device is greater than or equal to the preset threshold set by the processor. At this time, the processor can stop determining the third straight line and the third sampling point.

[0086] The processor can determine the connection lines between all the target positions according to all the determined target positions, and determine the direction of the optical cable according to the connection lines between all the obtained target positions. The processor can also determine the average value of the peak amplitude of each target position, and use the average value of the peak amplitude of each target position as the buried depth of the optical cable corresponding to each target position.

[0087] Through the above technical solution, the vibration signal of the sampling point can be collected to obtain the waveform of the vibration signal, so as to determine the buried position of the optical cable according to the waveform of the vibration signal, and determine the direction of the optical cable according to the buried position of the optical cable. The direction of the optical cable can be quickly located without excavation, reducing the manpower, material resources, financial resources and time consumed in locating the direction of the optical cable, which is conducive to the rapid repair and maintenance of the optical cable and increases the convenience of optical cable maintenance.
