Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments that can be derived by one of ordinary skill in the art from the description herein are intended to be within the scope of the present disclosure.
The method for positioning the fault point of the optical cable provided by the embodiment of the application can be executed by electronic equipment, and the electronic equipment can be equipment such as a smart phone, a tablet computer, a desktop computer and a server.
As shown in fig. 1, the embodiment of the present application provides an optical cable fault point positioning method, which includes:
s101, acquiring a first lighting distance between a measurement starting point and a fault point.
The first lighting distance is a lighting distance between the measurement starting point and the fault point acquired by emitting optical signals to the optical cable section to be measured at the measurement starting point.
In the embodiment of the application, the fault point is a breakpoint of an underground laid or overhead optical cable, and the measurement starting point is active equipment in a communication machine room capable of communicating with any section of the optical cable section to be measured with the fault point.
When a fault point exists in an optical cable section between two communication rooms, which causes communication interruption, a technician can view a fault warning from a port of equipment connected with the optical cable section in one of the communication rooms, and then the technician can transmit an optical signal to the port through the OTDR equipment, so that the optical signal is transmitted in the optical cable section connected with the port, and the lighting distance from active equipment in the communication rooms to the fault point of the optical cable section is measured.
Since the optical signal from the OTDR device reaches the fault point from the measurement starting point through the optical cable, the first illumination distance is the length of the optical cable between the measurement starting point and the fault point.
S102, determining a first reference point and a second reference point based on the first lighting distance and the lighting distance from the measurement starting point to each welding point on the optical cable section to be measured.
The first reference point is a welding point on one side of the fault point, which is closest to the fault point, and the second reference point is a welding point on the other side of the fault point, which is closest to the fault point;
in the embodiment of the present application, the optical cables connecting two communication rooms are generally fused from multiple sections of shorter optical cables, fusion joints exist between two adjacent sections of optical cables, and the optical distances from the communication rooms to the fusion joints can be measured by transmitting optical signals through OTDR equipment.
In one embodiment, for two adjacent communication rooms, a plurality of optical cable segments are arranged between the two adjacent communication rooms, and each optical cable segment has a welding point, so that the optical distance between the communication room and each welding point can be collected in advance through OTDR equipment, and the optical distance is stored in a database. Furthermore, when fault point positioning is performed, the electronic device can obtain the light irradiation distance from the measurement starting point to each welding point on the optical cable section to be measured from the database according to the measurement starting point and the information of the optical cable section to be measured, which are input by a user.
For example, an optical cable 1, an optical cable 2 and an optical cable 3 are arranged between the communication room 1 and the communication room 2, the optical cable 1 and the optical cable 2 are connected through a welding point a, and the optical cable 2 and the optical cable 3 are connected through a welding point B.
The optical cable may be polished in the direction of the communication room 2 at the communication room 1 using OTDR equipment, so that the polishing distance from the communication room 1 to the fusion point a and the polishing distance to the fusion point B are obtained.
And, the optical cable may be polished in the direction of the communication room 1 at the communication room 2 using the OTDR device, so as to obtain the polishing distance from the communication room 2 to the welding point a and the polishing distance to the welding point B.
S103, acquiring the position of the optical cable marking pile between the first datum point and the second datum point.
The optical cable identification pile is an identification pile arranged on the ground and used for identifying the position of an optical cable, a manhole of an underground pipeline, an electric pole of a pole line and the like, the optical cable is arranged under the optical cable identification pile, excavation is forbidden, and the position of the optical cable identification pile is the longitude and latitude of the optical cable identification pile.
In this embodiment of the application, a technician may collect, in advance, the longitude and latitude of the fusion point and the longitude and latitude of the optical cable identification pile on each optical cable segment through a Global Positioning System (GPS) Positioning device, and store the collected longitude and latitude into the database, and after the electronic device determines the position of the first reference point and the position of the second reference point, may obtain, from the database, the position of the optical cable identification pile between the first reference point and the second reference point.
And S104, determining the position of a fault point based on the first lighting distance and the position of the optical cable marking pile between the first reference point and the second reference point.
The method provided by the embodiment of the application determines the first reference point and the second reference point of the fault point by acquiring the first lighting distance of the fault point and based on the first lighting distance of the fault point and the lighting distance of each welding point on the cable segment to be tested, accurately positions the range of the fault point of the optical cable between the first reference point and the second reference point, equivalently removes the influence of the reserved optical cable on the cable segment to be tested and the bending distribution of the optical cable from the first reference point to the second reference point on the positioning of the fault point, greatly improves the positioning accuracy of the fault point, calculates by integrating the position of the optical cable identification pile between the first reference point and the second reference point and the first lighting distance, and then can obtain the position of the fault point, the influence of the bending distribution of the optical cable between the first datum point and the second datum point on the positioning of the optical cable fault point can be reduced, and the positioning accuracy of the optical cable fault point is improved.
In another embodiment of the present disclosure, as shown in fig. 2, the method includes the steps of:
s201, obtaining Information of a measurement starting point and a to-be-measured optical cable segment input by a user on a Geographic Information System (GIS) interface.
S202, receiving a measurement instruction of a user.
The technician may input information of the first lighting distance, the measurement starting point, and the cable segment to be measured into the electronic device, click the start measurement button, and accordingly, the electronic device may receive a measurement instruction from the user.
In practice, the cable connecting A, B between two telecommunication rooms consists of multiple cores, but not all of the cores in the cable are connected from a to B, and there may be an optical cross-over point in the cable between AB, where a portion of the cores in the length of cable are tapped to other telecommunication rooms at the optical cross-over point.
Therefore, the user has two input modes on the fault point query interface:
first, as shown in fig. 3a, if all the cores of the optical cable segment between the communication rooms AB are not tapped, the first illumination distance, the measurement starting point, and the measurement direction need to be input in the query interface.
Secondly, as shown in fig. 3B, if part of fiber cores of the optical cable segments between the communication rooms AB are connected to other rooms, and the port connecting the fiber cores of the B room in the a room is 2TA-01-02-a-2-11-1, it is necessary to input the first illumination distance on the query interface, measure the starting point, and connect the fiber core port 2TA-01-02-a-2-11-1 of the B room in the a room.
S203, responding to the measurement instruction, acquiring a first lighting distance between the measurement starting point and the fault point, and acquiring the lighting distance between the measurement starting point and each welding point on the optical cable section to be measured based on the information of the optical cable section to be measured.
After S203, S102 to S104 may be performed.
By adopting the method, a user only needs to input the information of the first lighting distance, the measurement starting point and the cable segment to be measured and click the measurement button, so that the fault point can be accurately positioned, the fault point is positioned without depending on manual calculation, and the operation is simple and quick.
In another embodiment of the present application, as shown in fig. 4, on the basis of the foregoing embodiment, S102 may be specifically implemented as:
and S1021, determining a target welding point closest to the fault point based on the first lighting distance and the lighting distance from the measurement starting point to each welding point on the optical cable section to be measured.
S1021 may be specifically implemented as:
subtracting the first lighting distance from the measurement starting point to each welding point on the optical cable section to be measured, and taking the absolute value of each difference to obtain the distance between each welding point and a fault point;
and determining the minimum value of the distance between each welding point and the fault point to obtain a target welding point closest to the fault point.
I.e. can be realized by the following formula:
P＝min(|BM1-BP|,|BM2-BP|,…,|BMn-BP|)
the method comprises the following steps that P is a target fusion point closest to a fault point, BMn represents the lighting distance from a measurement starting point to the nth fusion point on an optical cable section to be measured, BP represents the OTDR lighting distance from the current fault point to the measurement starting point, namely the lighting distance from the measurement starting point to the fault point, and in actual operation, the measurement starting point of a BMn value, the measurement starting point of a BP value and the measured optical cable section are kept consistent, so that the OTDR lighting directions of the BMn and the BP value are kept consistent.
And | BM1-BP |, | BM2-BP |, …, | BMn-BP | respectively represent the distance between each welding point and a fault point.
And (3) obtaining the minimum value in the | BM1-BP |, | BM2-BP |, …, | BMn-BP |, namely determining the minimum value of the distance between each welding point and the fault point, and obtaining the target welding point closest to the fault point.
For example, if the minimum distance between each welding point and the fault point is | BM2-BP |, the target welding point is determined to be the welding point corresponding to the polishing distance BM 2.
The method is characterized in that the distance between the measurement starting point and each welding point on the optical cable section to be measured is subtracted from the first lighting distance, the absolute value of each difference is obtained, the length of the optical cable between each welding point and a fault point is obtained equivalently, and then the minimum value of the absolute value of each difference is determined equivalently to determine the welding point with the shortest length of the optical cable between the welding point and the fault point, namely the target welding point closest to the fault point is determined, the target welding point closest to the fault point can be determined accurately, and the accuracy of fault point positioning is improved.
And S1022, if the second lighting distance from the measurement starting point to the target fusion point is less than the first lighting distance, determining that the first reference point is the target fusion point, and the second reference point is the next fusion point of the target fusion point in the direction from the measurement starting point to the target fusion point.
For example, as shown in fig. 5a, the measurement starting point is the machine room a, the fault point is C, and the target fusion point is B, it can be understood that three ACB points are on the same optical cable segment, the light distance from a to B is the second light distance, and the light distance from a to C is the first light distance.
Assuming that in the direction from A to B, the next welding point of B is E, and the last welding of B is D;
if the second lighting distance is smaller than the first lighting distance, B is the first reference point, and E is the second reference point.
And S1023, if the second lighting distance is larger than the first lighting distance, the second reference point is the target welding point, and the first reference point is the previous welding point of the target welding point in the direction from the measurement starting point to the target welding point.
In the above example, as shown in fig. 5B, if the second lighting distance is greater than the first lighting distance, B is the second reference point, and D is the first reference point.
In another embodiment of the present application, if the first lighting distance is equal to the second lighting distance, the position of the fault point coincides with the position of the target fusion point, and at this time, the electronic device may directly determine that the position of the fault point is the position of the target fusion point.
By adopting the method, the target welding point closest to the fault point can be determined through the first lighting distance and the lighting distance of each welding point on the optical cable section to be measured, and the position relation between the target welding point and the fault point can be obtained by comparing the size relation between the first lighting distance and the second lighting distance from the measurement starting point to the target welding point. Furthermore, the weld on the other side of the fault point closest to the fault point can be determined, i.e. the position of the fault point is accurately positioned between two adjacent welds, i.e. between the first reference point and the second reference point. The lighting distance can reflect the real length of the optical cable between the measurement starting point and the fault point or the fusion point, so that the fault point is positioned between the first reference point and the second reference point, the influence of the reserved length of the optical cable and the bending of the optical cable except the first reference point and the second reference point on the positioning precision of the fault point is eliminated, and the positioning accuracy is improved.
In another embodiment of the present application, on the basis of the above embodiment, the step S104 may be specifically implemented as:
first, the position information of the curve from the first reference point to the second reference point is acquired through the st _ maker () function:
geometryBM＝st_makeline(geometry[g1、g2…gn-1、gn])
g1 is GIS information corresponding to the longitude and latitude of the first reference point, gn is GIS information corresponding to the longitude and latitude of the second reference point, and g2 … gn-1 sequentially represents GIS information corresponding to the longitude and latitude of the optical cable identification pile in the direction from the first reference point to the second reference point.
The function st _ along () in the built-in function of the PostGIS is a function of generating a line from positions of a plurality of points, and in the embodiment of the present application, the function may generate a curve in the order of g1, g2 … gn-1, gn, and both ends of the curve are a first reference point and a second reference point.
The geometry () is used to convert data types, and since g1, g2 … gn-1, gn in the present application are GIS information corresponding to longitude and latitude, which are data types of individual points, the function st _ makeline () may convert data types of points into data types of lines, that is, the generated geometry bm is the position information of a curve from a first reference point to a second reference point.
The built-in function ST _ lineintepolatepoint () of the PostGIS is introduced:
the function ST _ linelnterplatetpoint () is a function for calculating the position of an unknown point in the case where the conditions 1 and 2 are satisfied.
Wherein the unknown point is located between two end points, and the condition 1 is that the positions of the two end points are known and the positions of a plurality of points between the two end points are known.
Condition 2 is the ratio of the distance between the known unknown point to one of the end points to the distance between the two end points.
The application scenario of the built-in function is replaced by the scenario in the embodiment of the present application, that is, in the embodiment of the present application, the two end points are the first reference point and the second reference point, the unknown point is the failure point, and the position between the two end points is the position of the optical cable identification stub between the first reference point and the second reference point.
Through the scene replacement, a GIS positioning formula of the fault point can be obtained:
Bpgeometry＝ST_LineInterpolatePoint(geometryBM,(BP-BMg1)/(ST_Length(sd_st_transform(geometryBM,26986))))；
wherein Bpgeometry is the position of a fault point;
geomtyBM is position information of a curve between a first reference point and a second reference point;
BP is a first light emitting distance;
BMg1 is the polishing distance from the test starting point to the first reference point;
a function sd _ st _ transform (, 26986) is used to convert the position information of the curve between the first reference point to the second reference point into position coordinates in a 26986 coordinate system;
the function ST _ Length () calculates the Length of a curve between the first reference point and the second reference point in the 26986 coordinate system from the converted coordinate points of the 26986 coordinate system.
It can be understood that (BP-BMg1)/(ST _ Length (sd _ ST _ transform (geometribm, 26986))) is a ratio of a distance from a first reference point to a fault point to a Length of a curve from the first reference point to a second reference point, and then, the function ST _ linenterpolatepoint () can calculate the longitude and the latitude of the fault point according to the ratio and the geometribm.
It should be noted that the function ST _ linelnterplatetpoint () and the function ST _ makeline () are all built-in functions of the PostGIS, and the calculation principle of the above functions can be referred to the related description.
By adopting the method, based on a PostGIS routing positioning principle, GIS information corresponding to the longitude and latitude of a first reference point, GIS information corresponding to the longitude and latitude of a second reference point and GIS information corresponding to the longitude and latitude of an optical cable identification pile between the first reference point and the second reference point are used for generating position information of a curve from the first reference point to the second reference point, the position information of the curve is converted into a position coordinate in a 26986 coordinate system, then the Length of the curve in the 26986 coordinate system is calculated based on the coordinate and a function ST _ Length (), the straight-line distance between the first reference point and the second reference point is not directly calculated, so that the calculated Length of the curve between the first reference point and the second reference point is closer to the Length of the optical cable bent between the first reference point and the second reference point, and the ratio of the distance from the first reference point to a fault point to the Length of the curve from the first reference point to the second reference point is calculated, thereby enabling more accurate calculation of the position of the failure point in the direction from the first reference point to the second reference point. Furthermore, by combining the position information of the curve between the first reference point and the second reference point, the position of the fault point can be obtained through the function ST _ LineInterpoletetPoint (), the influence of optical cable reservation and optical cable bending on the positioning of the fault point can be reduced to the greatest extent, and the accuracy of the positioning of the fault point is effectively improved.
In the embodiment of the present application, as shown in fig. 6, on the basis of the above embodiment, after step S104, the method further includes:
s601, displaying the position of the fault point on a GIS map of a GIS interface.
