Description

Technical Field

[0001] The present application relates to the field of communication optical cables, and in particular to a method, a processor and a storage medium for determining the coiled length of an optical cable. Background Art

[0002] Communication optical cables have a very important influence on people's lives and work. 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 process, buried communication optical cables are laid in sections, and then connected section by section. At the connection point between every two sections, an optical cable junction box is set up, and a certain length of optical cable is coiled. In the later stage, when the broken cable is repaired and re-splice, a junction box is also required, and the optical cable is coiled. However, due to problems such as non-standard construction, missing construction records, and missing electronic identification, the length of the optical cable cannot correspond to the actual distance on the ground. When repairing the broken optical cable, it is impossible to quickly determine the ground coordinate position based on the distance of the broken cable. At present, if you want to know the actual length of the optical cable on the cable coil, you can only excavate and measure the cable coil with missing information, which will consume a lot of manpower, material resources, financial resources and time.

[0038] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0039] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0040] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present application, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0041] like Figure 1 As 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.

[0042] 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.

[0043] 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.

[0044] like Figure 2 As shown, a flow chart of a method for determining the coiling length of an optical cable in the present application is schematically shown, such as Figure 2 As shown, the following steps are included:

[0045] Step 201, tapping each sampling point in turn at a preset frequency to obtain a vibration signal of each sampling point;

[0046] Step 202, when the frequency of the vibration signal meets the preset frequency, obtaining the waveform of the vibration signal;

[0047] Step 203, analyzing the waveform of the vibration signal to determine the target area where the cable is coiled, and determining the cable mileage of the target area and the ground distance of the target area;

[0048] Step 204, determining the coiled length of the optical cable according to the cable mileage and the ground distance.

[0049] A plurality of sampling points can be set above the buried optical cable. For example, the sampling points are set along the axial direction of the optical cable, and a sampling point is set every 10 meters. Each sampling point can be tapped in turn, so that the processor obtains the vibration signal of the buried optical cable at each sampling point. The processor can set the tapping frequency, and the obtained vibration signal should correspond to the tapping frequency and meet the preset frequency. For example, assuming that the frequency of tapping the ground is 1 second at an interval of 1 second, tapping once per second, and a total of 5 tapping times, in order to distinguish other interfering vibration signals, the processor can set the preset frequency of the vibration signal to correspond to 1 tapping feature every second, and 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, the processor can analyze the waveform of the obtained vibration signal to determine the target area where the cable is located, and determine the cable mileage of the target area and the ground distance of the target area. After the processor determines the cable mileage and ground distance of the target area where the cable is located, the cable coiling length can be determined according to the cable mileage and ground distance. The cable coiling length refers to the length of the optical cable stored on the cable coil.

[0050] In one embodiment, analyzing the waveform of the vibration signal to determine the target area where the optical cable is coiled includes: when the first waveform in the waveform of the vibration signal is located on the left side of the second waveform, determining the sampling point corresponding to the vibration signal as the first target sampling point; when the first waveform in the waveform of the vibration signal is located on the right side of the second waveform, determining the sampling point corresponding to the vibration signal as the second target sampling point; and determining the area between the first target sampling point and the second target sampling point as the target area where the optical cable is coiled.

[0051] The processor can obtain a vibration signal of a sampling point. When the waveform corresponding to the vibration signal of the sampling point obtained by the processor includes a first waveform and a second waveform, and the first waveform is located on the left side of the second waveform, the sampling point corresponding to the vibration signal is determined as a first target sampling point. When the waveform of the vibration signal includes a first waveform and a second waveform, and the first waveform is located on the right side of the second waveform, the processor can determine the sampling point corresponding to the vibration signal as a second target sampling point. The area between the first target sampling point and the second target sampling point is determined as the target area where the cable is coiled.

[0052] In one embodiment, determining the optical cable mileage of the target area and the ground distance of the target area includes: determining a first optical cable length between the first optical cable position and the positioning device according to the optical cable positions corresponding to the first waveform and the second waveform in the waveform corresponding to the first target sampling point; determining a second optical cable length between the second optical cable position and the positioning device according to the optical cable positions corresponding to the first waveform and the second waveform in the waveform corresponding to the second target sampling point; and determining the difference between the first optical cable length and the second optical cable length as the optical cable mileage of the target area where the optical cable is coiled.

[0053] After the processor determines the first target sampling point and the second target sampling point, the processor can obtain the waveform of the vibration signal corresponding to the first target sampling point, and analyze the waveform of the vibration signal corresponding to the first target sampling point to determine the optical cable positions corresponding to the first waveform and the second waveform, thereby determining the first optical cable length between the first optical cable position and the position where the positioning device is located according to the optical cable positions corresponding to the first waveform and the second waveform. The processor can obtain the waveform of the vibration signal corresponding to the second target sampling point, and analyze the waveform of the vibration signal corresponding to the first target sampling point to determine the optical cable positions corresponding to the first waveform and the second waveform, thereby determining the second optical cable length between the second optical cable position and the position where the positioning device is located according to the optical cable positions corresponding to the first waveform and the second waveform. After the processor determines the first optical cable length and the second optical cable length, the processor can determine the difference between the first optical cable length and the second optical cable length as the optical cable mileage of the target area where the optical cable is coiled.

[0054] In one embodiment, determining the first optical cable length between the first optical cable position and the positioning device according to the optical cable positions corresponding to the first waveform and the second waveform in the waveform corresponding to the first target sampling point includes: obtaining the first waveform distance between the waveform position corresponding to the rightmost end of the first waveform and the waveform position corresponding to the leftmost end of the second waveform; when it is determined that the first waveform and the second waveform do not overlap and the first waveform distance is less than a preset distance, determining the optical cable position corresponding to the central peak of the first waveform as the first optical cable position; and determining the optical cable length between the position of the positioning device and the first optical cable position as the first optical cable length.

[0055] After the processor obtains the waveform of the vibration signal corresponding to the first target sampling point, that is, when the obtained waveform includes the first waveform and the second waveform, and the first waveform is located on the left side of the second waveform, the processor can obtain the first waveform distance between the waveform position corresponding to the rightmost end of the first waveform and the waveform position corresponding to the leftmost end of the second waveform. When it is determined that the first waveform and the second waveform do not overlap, and the first waveform distance is less than the preset distance set by the processor, the processor can determine the optical cable position corresponding to the central peak of the first waveform, and determine the optical cable position corresponding to the central peak of the first waveform as the first optical cable position. After the processor determines the first optical cable position, the processor can determine the optical cable length between the position of the positioning device and the first optical cable position as the first optical cable length.

[0056] In one embodiment, determining the second optical cable length between the second optical cable position and the positioning device according to the optical cable positions corresponding to the first waveform and the second waveform in the waveform corresponding to the second target sampling point includes: obtaining the second waveform distance between the waveform position corresponding to the leftmost end of the first waveform and the waveform position corresponding to the rightmost end of the second waveform; when it is determined that the first waveform and the second waveform do not overlap and the second waveform distance is less than a preset distance, determining the optical cable position corresponding to the central peak of the first waveform as the second optical cable position; and determining the optical cable length between the position of the positioning device and the second optical cable position as the second optical cable length.

[0057] After the processor obtains the waveform of the vibration signal corresponding to the second target sampling point, that is, when the obtained waveform includes the first waveform and the second waveform, and the first waveform is located on the right side of the second waveform, the processor can obtain the second waveform distance between the waveform position corresponding to the leftmost end of the first waveform and the waveform position corresponding to the rightmost end of the second waveform. When it is determined that the first waveform and the second waveform do not overlap, and the second waveform distance is less than the preset distance set by the processor, the processor can determine the optical cable position corresponding to the central peak of the first waveform, and determine the optical cable position corresponding to the central peak of the first waveform as the second optical cable position. After the processor determines the second optical cable position, the processor can determine the optical cable length between the position of the positioning device and the second optical cable position as the second optical cable length.

[0059] After the processor determines the first optical cable position and the second optical cable position, the processor can determine the first ground position corresponding to the first optical cable position based on the first optical cable position, and determine the second ground position corresponding to the second optical cable position based on the second optical cable position. After determining the first ground position and the second ground position, the processor can determine the distance between the first ground position and the second ground position as the ground distance of the target area.

[0060] In one embodiment, determining the coiled length of the optical cable according to the cable mileage and the ground distance includes: determining the difference between the cable mileage and the ground distance, and determining the difference as the coiled length of the optical cable.

[0061] After determining the first optical cable length and the second optical cable length, the processor may determine the difference between the first optical cable length and the second optical cable length as the optical cable mileage of the target area where the optical cable is coiled. After determining the first ground position and the second ground position, the processor may determine the distance between the first ground position and the second ground position as the ground distance of the target area. The processor may determine the difference between the optical cable mileage in the target area and the ground distance in the target area, and determine the obtained difference as the coiled length of the optical cable.

[0062] In one embodiment, analyzing the waveform of the vibration signal to determine the target area where the optical cable is coiled includes: when the waveform of the vibration signal includes a first waveform and two second waveforms, and the first waveform is located on the left side of the two second waveforms, determining the sampling point corresponding to the vibration signal as the third target sampling point; when the waveform of the vibration signal includes a first waveform and two second waveforms, and the first waveform is located on the right side of the two second waveforms, determining the sampling point corresponding to the vibration signal as the fourth target sampling point; and determining the area between the third target sampling point and the fourth target sampling point as the target area where the optical cable is coiled.

[0063] Since the optical cable changes with the ground terrain, sometimes the distance between two optical cables is close, and the waveform of the vibration signal of the corresponding sampling point will also change. The processor can obtain the waveform of the vibration signal of the sampling point. When the waveform of the vibration signal includes a first waveform and two second waveforms, and the first waveform is located on the left side of the two second waveforms, the processor can determine the sampling point corresponding to the vibration signal as the third target sampling point.

[0065] After the processor determines the target area between the third target sampling point and the fourth target sampling point, the processor may set a plurality of sampling points in the target area, and sequentially obtain vibration signals of the sampling points. When the waveform of the vibration signal of the obtained sampling points includes a third waveform and two second waveforms, and the second waveforms are respectively located on both sides of the third waveform, the processor may determine the sampling point corresponding to the vibration signal as the fifth target sampling point. The peak of the third waveform is higher than that of the second waveform and the third waveform appears earlier than the second waveform.
