In the above operating environment, an embodiment of the present application provides a method for locating an optical fiber fault, as shown in fig. 2, where the method includes the following steps:
step S202, determining a target distance between a fault point on the target optical fiber and an optical fiber endpoint of the target optical fiber;
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 light signal on the target optical fiber through a second optical time domain reflectometer, wherein the reflected light signal is a reflected signal of an optical signal emitted by the second optical time domain reflectometer, and the second optical time domain reflectometer is arranged at an optical fiber endpoint of the target optical fiber; and determining the distance between the signal intensity mutation point and the second optical time domain reflectometer as a target distance.
Specifically, the signal intensity of the reflected light signal corresponding to each place in the optical fiber in the normal operation 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 suddenly drops, so the point where the reflected light intensity suddenly drops can be regarded as the fault point. In addition, it should be noted that, in addition to the optical fiber fault point in the conventional sense, the fault point in the embodiment of the present application further includes a point of large optical attenuation, that is, a point of excessive attenuation of the optical signal, which is specifically expressed in a form of a dip of the optical signal intensity at the point.
As an alternative embodiment, 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 the multiple reference points may also be determined by: determining the optical port distance between each optical port on the test optical fiber and the optical fiber port of the test optical fiber through a first optical time domain reflectometer, wherein the test optical fiber is parallel to the target optical fiber, the optical fiber end point of the test optical fiber and the optical fiber end point of the target optical fiber are positioned at the same position, and the first optical time domain reflectometer is arranged at the optical fiber port of the test optical fiber; determining longitude and latitude coordinates of each optical port; and 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 port of the test optical fiber into a reference point database.
Specifically, a plurality of optical fibers for transmitting signals, that is, the target optical fibers, are disposed in one optical cable, and in the embodiment of the present application, a peripheral detecting fiber core, that is, the test optical fiber, is additionally disposed in the optical cable. The test fiber is not used for transmitting service signals, but is only used for determining relevant information of the reference point. The optical fiber testing device comprises a testing optical fiber, wherein a plurality of optical ports are formed in the testing optical fiber, and a positioning instrument is arranged at each optical port and can be used for determining longitude and latitude coordinates of the optical port. The port of the test optical fiber is provided with a first optical time domain reflectometer, and the distance between each optical port and the port of the test optical fiber can be periodically measured. It can be seen that the distance and longitude and latitude information corresponding to each optical port is the distance and longitude and latitude information of the reference point.
After the distance and longitude and latitude information of each reference point are obtained, the distance and longitude and latitude information of the reference point can be stored in a reference point database and used for determining the specific position of the fault point later. The reference point database may be disposed in the cloud information platform.
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 longitude and latitude coordinates of the port of the optical fiber port of the test optical fiber; determining a first arrangement sequence of longitude and latitude coordinates of each optical port according to the longitude and latitude coordinates of the port, wherein the smaller the serial number of the longitude and latitude coordinates of each optical port in the first arrangement sequence is, the closer the distance between the longitude and latitude coordinates of each optical port and the longitude and latitude coordinates of the port is; determining a second arrangement sequence of the distances of all the light ports according to the sequence of the distances from small to large; and determining the corresponding optical port distance according to the first serial number of the port longitude and latitude coordinates in the first arrangement sequence, wherein the serial number of the corresponding optical port distance in the second arrangement sequence is a second serial number, and the second serial number is equal to the first serial number.
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 for storing 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 in the reference points with the distance smaller than the target distance, and the second reference point is the reference point closest to the optical fiber endpoint in the reference points with the distance larger than the target distance;
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.
In the technical solution provided in step S206, the step of 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 includes: determining a first distance between the first reference point and the fault point according to the distance between the first reference point and the optical fiber port and the target distance; determining a second distance between the second reference point and the fault point according to the distance between the second reference point and the optical fiber port and the target distance; and determining the predicted longitude and latitude coordinates of the fault point according to the first distance, the second distance, the first longitude and latitude coordinates and the second longitude and latitude coordinates.
Specifically, the step of determining the predicted longitude and latitude coordinates of the fault point according to the first distance, the second distance, the first longitude and latitude coordinates and the second longitude and latitude coordinates includes: determining a third distance between the first reference point and the second reference point according to 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; and determining the predicted longitude and latitude coordinates according to the first ratio and the second ratio.
As an alternative embodiment, the determination of the predicted longitude and latitude coordinates by the first ratio, the second ratio, the first longitude and latitude coordinates and the second longitude and latitude coordinates may be performed as follows. A fourth distance between the first reference point and the second reference point may first be determined from the first latitude and longitude coordinates and the second latitude and longitude coordinates. Here, the fourth distance and the third distance are ideally equal, where ideally means that the optical fiber is a straight line between the first reference point and the second reference point, and there is no bending portion. However, in practical situations, a certain radian will inevitably exist in the optical fiber between the first reference point and the second reference point, and uneven distribution of the material of the optical fiber and errors 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 generally short, the above deviation can be ignored, that is to say the optical fiber between the first reference point and the second reference point can be approximately considered as a straight line.
Thus, after the fourth distance is determined, a first predicted fault point may be determined in a line connecting the first reference point and the second reference point based on the first scale, and a second predicted fault point may be determined in a line connecting the first reference point and the second reference point based on the second scale based on the second reference point. Specifically, the product of the fourth distance and the first ratio may be considered to be the distance between the first predicted fault point and the first reference point, and the product of the fourth distance and the second ratio may be considered to be the distance between the second predicted fault point and the second reference point.
In an ideal case, the first predicted fault point and the second predicted fault point should be the same point, but in the actual test process, the first predicted fault point and the second predicted fault point will not normally coincide. At this time, the midpoint of the line between the first predicted fault point and the second predicted fault point may be considered as the finally determined predicted fault point, and the longitude and latitude coordinates of the point are also referred to as predicted longitude and latitude coordinates.
In some embodiments of the present application, after the step of 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, a search range centered on the predicted longitude and latitude coordinates may be determined according to the predicted longitude and latitude coordinates, and the predicted longitude and latitude coordinates and the search range may be pushed to the target object; acquiring actual longitude and latitude information of a fault point input by a target object; and replacing the predicted longitude and latitude information of the fault point with the actual longitude and latitude information, and storing the target distance and the actual longitude and latitude information of the fault point into a reference point database.
The embodiment of the application also provides an optical fiber fault positioning process. Fig. 3 is a flow chart of an optical fiber fault locating process according to an embodiment of the present application, as shown in fig. 3, where the process includes:
step S302, determining the optical port distance of each optical port on the peripheral detection fiber core through a first optical time domain reflectometer;
step S304, testing longitude and latitude information of each optical port through a position meter;
step S306, matching longitude and latitude information of each optical port with the optical port distance;
step S308, determining a target distance corresponding to the fault point through a second optical time domain reflectometer;
step S310, predicting longitude and latitude information of a fault point according to the target distance;
step S312, the predicted longitude and latitude information is replaced by the actual longitude and latitude information of the fault point, and the target distance and the actual longitude and latitude information corresponding to the fault point are stored in the reference point database.
Specifically, the optical fiber fault locating method shown in fig. 2 and the optical fiber fault locating flow shown in fig. 3 may be used in the optical fiber fault locating system shown in fig. 4. As can be seen from fig. 4, a GIS map may also be provided in the optical fiber fault location system, to assist in determining latitude and longitude information of each point. In fig. 4, OTDR1 represents a first optical time domain reflectometer, OTDR2 represents a second optical time domain reflectometer, and the optical ports that are amplified step by step refer to that the attenuation degree of the optical signal corresponding to each optical port set in the peripheral detection fiber core is gradually increased, that is, the farther from the optical time domain reflectometer, the larger the signal intensity mutation amplitude is, so that the speed of determining the position of the optical port can be increased.
Determining a target distance between a fault point on the target optical fiber and an optical fiber end point of the target optical fiber; 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 for storing 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 in the reference points with the distance smaller than the target distance, and the second reference point is the reference point closest to the optical fiber endpoint in the reference points with the distance larger than the target distance; 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, and the predicted longitude and latitude coordinates of the fault point are determined through the predetermined longitude and latitude coordinates of the reference point, so that the purpose that the approximate position of the fault point can be determined without on-site measurement of operation and maintenance personnel is achieved, the technical effect of improving the fault positioning speed is achieved, and the technical problem that the fault point cannot be determined in time due to the fact that the operation and maintenance personnel are required to measure on-site and determine the position of the fault point according to experience in the related art is solved.
