[0033] Under the above operating environment, the embodiment of the present application provides a method for locating optical fiber faults, such as Figure 2 As shown, the method comprises the following steps:

[0034] Step S202, determining a target distance between a fault point on a target optical fiber and an optical fiber end point of the target optical fiber;

[0035] In the technical solution provided in step S202, the step of determining the target distance between the fault point on the target optical fiber and the optical fiber end point of the target optical fiber includes: determining a signal intensity mutation point of a reflected optical signal on the target optical fiber by a second optical time domain reflectometer, wherein the reflected optical signal is a reflection signal of an optical signal emitted by the second optical time domain reflectometer, and the second optical time domain reflectometer is arranged at the optical fiber end point of the target optical fiber; and determining the distance between the signal intensity mutation point and the second optical time domain reflectometer as the target distance.

[0036] Specifically, the signal intensity of the reflected light signal corresponding to each point in the normally working optical fiber is proportional to the distance from the point to the second optical time domain reflectometer, and at the fault point, the signal intensity of the reflected light signal will drop sharply, so the point where the reflected light intensity drops sharply can be considered as the fault point. In addition, it should be noted that the fault point described in the embodiment of the present application includes, in addition to the conventional optical fiber fault point, a point where the optical signal attenuation is too large, which is specifically manifested in that the optical signal intensity drops sharply at this point.

[0037] As an optional implementation, before the step of determining the target distance between the fault point on the target optical fiber and the optical fiber end point of the target optical fiber, the distances and longitude and latitude coordinates corresponding to multiple reference points can also be determined in the following manner: determining the optical port distances between each optical port on the test optical fiber and the optical fiber end point of the test optical fiber by a first optical time domain reflectometer, wherein the test optical fiber and the target optical fiber are parallel, the optical fiber end point of the test optical fiber and the optical fiber end point of the target optical fiber are located at the same position, and the first optical time domain reflectometer is arranged at the optical fiber end point of the test optical fiber; determining the longitude and latitude coordinates of each optical port; matching the longitude and latitude coordinates of each optical port with the optical port distance of each optical port, and storing the matched longitude and latitude coordinates of each optical port and the distance between each optical port and the optical fiber end point of the test optical fiber in a reference point database.

[0038] Specifically, a plurality of optical fibers for transmitting signals, namely, the target optical fibers, are provided in an optical cable, and in the embodiment of the present application, an additional peripheral detection core, namely, the test optical fiber, is provided in the optical cable. The test optical fiber will not be used to transmit service signals, but is only used to determine the relevant information of the reference point. Among them, a plurality of optical ports are provided on the test optical fiber, and a locator is provided at each optical port, which can be used to determine the longitude and latitude coordinates of the optical port. A first optical time domain reflectometer is installed at the port of the test optical fiber, which can periodically measure the distance between each optical port and the port of the test optical fiber. It can be seen that the distance and longitude and latitude information corresponding to each optical port are the distance and longitude and latitude information of the reference point.

[0039] After obtaining the distance and longitude and latitude information of each reference point, the distance and longitude and latitude information of the reference point can be stored in a reference point database for subsequent determination of the specific location of the fault point. The reference point database can be set in a cloud information platform.

[0040] In some embodiments of the present application, the step of matching the longitude and latitude coordinates of each optical port with the optical port distance of each optical port includes: determining the port longitude and latitude coordinates of the optical fiber port of the test optical fiber; determining a first arrangement order of the longitude and latitude coordinates of each optical port based on the port longitude and latitude coordinates, wherein the smaller the serial number of the longitude and latitude coordinates of each optical port in the first arrangement order, the closer the distance between the longitude and latitude coordinates of each optical port and the port longitude and latitude coordinates; determining a second arrangement order of the optical port distances in order from small to large; determining the corresponding optical port distance based on the first serial number of the port longitude and latitude coordinates in the first arrangement order, wherein the serial number of the corresponding optical port distance in the second arrangement order is the second serial number, and the second serial number is equal to the first serial number.

[0041] Step S204, determining a first reference point and a second reference point from a reference point database according to the target distance, wherein the database is used to store the distance between each reference point on the target optical fiber and the optical fiber endpoint, and the longitude and latitude coordinates of each reference point, the first reference point is the reference point farthest from the optical fiber endpoint among the reference points whose distance to the optical fiber endpoint is less than the target distance, and the second reference point is the reference point closest to the optical fiber endpoint among the reference points whose distance to the optical fiber endpoint is greater than the target distance;

[0042] Step S206, determining the predicted longitude and latitude coordinates of the fault point according to the first longitude and latitude coordinates of the first reference point and the second longitude and latitude coordinates of the second reference point.

[0043] In the technical solution provided in step S206, the step of determining the predicted longitude and latitude coordinates of the fault point based on the first longitude and latitude coordinates of the first reference point and the second longitude and latitude coordinates of the second reference point includes: determining the first distance between the first reference point and the fault point based on the distance between the first reference point and the optical fiber port and the target distance; determining the second distance between the second reference point and the fault point based on the distance between the second reference point and the optical fiber port and the target distance; determining the predicted longitude and latitude coordinates of the fault point based on the first distance, the second distance, the first longitude and latitude coordinates and the second longitude and latitude coordinates.

[0044] Specifically, the step of determining the predicted longitude and latitude coordinates of the fault point based on the first distance, the second distance, the first longitude and latitude coordinates and the second longitude and latitude coordinates includes: determining the third distance between the first reference point and the second reference point based on the distance between the first reference point and the second reference point and the optical fiber port respectively; determining a first ratio between the first distance and the third distance, and a second ratio between the second distance and the third distance; determining the predicted longitude and latitude coordinates based on the first ratio, the second ratio, the first longitude and latitude coordinates and the second longitude and latitude coordinates.

[0045] As an optional implementation, the following method can be used to determine the predicted longitude and latitude coordinates based on the first ratio, the second ratio, the first longitude and latitude coordinates and the second longitude and latitude coordinates. First, the fourth distance between the first reference point and the second reference point can be determined based on the first longitude and latitude coordinates and the second longitude and latitude coordinates. It should be noted here that in an ideal case, the fourth distance is equal to the third distance, wherein the ideal case refers to the optical fiber being a straight line between the first reference point and the second reference point, without any curved parts. However, in actual situations, there is usually a certain curvature of the optical fiber between the first reference point and the second reference point, and the uneven distribution of the material of the optical fiber itself and the error of the optical time domain signal reflectometer will also cause a certain deviation between the third distance and the fourth distance. However, since the distance between the first reference point and the second reference point is usually short, the above deviation can be ignored, that is, the optical fiber between the first reference point and the second reference point can be approximately considered to be a straight line.

[0046] In this way, after the fourth distance is determined, the first predicted fault point can be determined in the line connecting the first reference point and the second reference point based on the first ratio and the first reference point as a reference, and the second predicted fault point can be determined in the line connecting the first reference point and the second reference point based on the second ratio and the second reference point as a reference. Specifically, it can be considered that the product of the fourth distance and the first ratio is the distance between the first predicted fault point and the first reference point, and the product of the fourth distance and the second ratio is the distance between the second predicted fault point and the second reference point.

[0047] Ideally, the first predicted fault point and the second predicted fault point should be the same point, but in actual testing, the first predicted fault point and the second predicted fault point usually do not overlap. In this case, the midpoint of the line connecting the first predicted fault point and the second predicted fault point can be considered as the final predicted fault point, and the longitude and latitude coordinates of this point are also the predicted longitude and latitude coordinates.

[0048] In some embodiments of the present application, after the step of determining the predicted longitude and latitude coordinates of the fault point based on the first longitude and latitude coordinates of the first reference point and the second longitude and latitude coordinates of the second reference point, it is also possible to determine a retrieval range centered on the predicted longitude and latitude coordinates based on the predicted longitude and latitude coordinates, and push the predicted longitude and latitude coordinates and the retrieval range to the target object; obtain the actual longitude and latitude information of the fault point input by the target object; replace the predicted longitude and latitude information of the fault point with the actual longitude and latitude information, and store the target distance and actual longitude and latitude information of the fault point in the reference point database.

[0049] An optical fiber fault locating process is also provided in an embodiment of the present application. Figure 3 FIG. 1 is a flow chart of the optical fiber fault location process provided in the embodiment of the present application. Figure 3 As shown, the process includes:

[0050] Step S302, determining the optical port distances of each optical port on the peripheral detection fiber core by a first optical time domain reflectometer;

[0051] Step S304, testing the longitude and latitude information of each optical port by using a position meter;

[0052] Step S306, matching the longitude and latitude information of each optical port and the optical port distance;

[0053] Step S308, determining the target distance corresponding to the fault point by a second optical time domain reflectometer;

[0054] Step S310, calculating the predicted longitude and latitude information of the fault point according to the target distance;

[0055] Step S312, replacing the predicted longitude and latitude information with the actual longitude and latitude information of the fault point, and storing the target distance and the actual longitude and latitude information corresponding to the fault point in the reference point database.

[0056] Specifically, Figure 2 The optical fiber fault location method shown in Figure 3 The fiber fault location process shown in Figure 4 In the optical fiber fault location system shown in FIG. Figure 4 It can be seen from the figure that a GIS map can also be provided in the optical fiber fault location system to assist in determining the longitude and latitude information of each point. Figure 4 OTDR1 represents the first optical time domain reflectometer, OTDR2 represents the second optical time domain reflectometer, and the step-by-step amplification of the optical port means that the attenuation of the optical signal corresponding to each optical port set in the peripheral detection fiber core will gradually increase, that is, the farther from the optical time domain reflectometer, the greater the amplitude of the signal strength mutation, which can speed up the speed of determining the position of the optical port.

[0057] By determining the target distance between the fault point on the target optical fiber and the optical fiber end point of the target optical fiber; determining the first reference point and the second reference point from the reference point database according to the target distance, wherein the database is used to store the distance between each reference point on the target optical fiber and the optical fiber end point, and the longitude and latitude coordinates of each reference point, the first reference point is the reference point with the farthest distance from the optical fiber end point among the reference points with a distance from the optical fiber end point less than the target distance, and the second reference point is the reference point with the closest distance to the optical fiber end point among the reference points with a distance from the optical fiber end point greater than the target distance; determining the predicted longitude and latitude coordinates of the fault point according to the first longitude and latitude coordinates of the first reference point and the second longitude and latitude coordinates of the second reference point, the predicted longitude and latitude coordinates of the fault point are determined by the predetermined longitude and latitude coordinates of the reference point, so as to achieve the purpose of determining the approximate position of the fault point without on-site measurement by operation and maintenance personnel, thereby achieving the technical effect of improving the speed of fault location, and further solving the technical problem that the position of the fault point cannot be determined in time due to the need for on-site measurement by operation and maintenance personnel and determining the position of the fault point based on experience in the related technology.
