It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.
[0024] Figure 1 is a flow chart of a method for maintaining optical cable routing information provided according to an embodiment of the present application, such as Figure 1 As shown, the method comprises the following steps:
[0025] Step S102, detecting the storage status of routing information of the target optical cable, wherein the target optical cable includes: a first optical cable segment storing the optical cable routing information and / or a second optical cable segment lacking the optical cable routing information;
[0026] Step S104, for the first optical cable segment, obtaining first optical cable routing information and inspection path information corresponding to the first optical cable segment; determining a difference path between the optical cable route indicated by the first optical cable routing information and the inspection path indicated by the inspection path information; and correcting the first optical cable routing information according to the on-site verification result of the optical cable laying status of the difference path;
[0027] Step S106, for the second optical cable segment, obtain the optical cable duct and pole line routing information in the target area including the optical cable starting point and the optical cable end point of the second optical cable segment; measure the optical cable length of the second optical cable segment, and generate the target optical cable path based on the optical cable duct and pole line routing information and the optical cable length; generate the second optical cable routing information corresponding to the second optical cable segment based on the point-by-point verification result of the optical cable laying status of each verification point in the target optical cable path, wherein, when no optical cable is detected at any verification point, it is determined that the verification of the verification point has failed, and the path in the target optical cable path that has not been completed is updated based on the optical cable duct and pole line routing information, the optical cable length and the length of the path in the target optical cable path that has been completed.
[0028] The following describes the various steps of the optical cable routing information maintenance method in conjunction with a specific implementation process.
[0029] Due to various factors such as frequent splicing of existing optical cables and untimely updates of optical cable routes, there is a large difference between the existing optical path routing data and the actual optical cable routing. This application compares the optical cable routing with the inspection path of maintenance personnel, and automatically discovers and corrects erroneous optical cable routing information by analyzing the difference data between the two, thereby helping to improve the accuracy of optical cable routing data.
[0030] First, the routing information storage status of the target optical cable is detected, wherein the target optical cable includes: a first optical cable segment storing the optical cable routing information and / or a second optical cable segment lacking the optical cable routing information.
[0031] For the first optical cable segment, first optical cable routing information and inspection path information corresponding to the first optical cable segment are obtained.
[0032] Generally, when analyzing the routing information of the first optical cable, when the routing information of the first optical cable is completely consistent with the inspection path information of the maintenance personnel, it means that the routing information of the optical cable is accurate. However, due to the influence of various external environmental factors, it is impossible for the inspection personnel to inspect completely along the path where the optical cable is located. There must be a certain distance between the routing information of the first optical cable and the inspection path information of the maintenance personnel in space. Therefore, after obtaining the routing information of the first optical cable and the inspection path information, it is necessary to determine the difference path between the optical cable route indicated by the first optical cable routing information and the inspection path indicated by the inspection path information.
[0033] Optionally, the difference path includes a first difference path corresponding to the optical cable routing and a second difference path corresponding to the inspection path. The difference path between the optical cable routing indicated by the first optical cable routing information and the inspection path indicated by the inspection path information can be determined by the following steps: determine the first linear path corresponding to the optical cable routing indicated by the first optical cable routing information, and extend each point in the first linear path to both sides of the path by a preset distance to obtain a strip path surface; determine the second linear path corresponding to the inspection path indicated by the inspection path information; determine each path segment in the second linear path that is not located in the strip path surface as the second difference path; determine the path in each strip path surface corresponding to each segment of the second difference path in the first linear path as the first difference path.
[0034] For example, based on the geometric principle of whether a line is within a surface, the built-in function ST_DWithin(geom1 geometry,geom2 geometry,Rdouble_precision) of the PG database is used to determine whether the maintenance personnel's inspection path geom1 is completely within the first linear path, forming a strip path surface geom2 after extending R (the default value is 50, which can be set manually) meters to both ends. If it is completely within, it means that the two paths are consistent and the optical cable routing information is accurate. If it is not completely within, it means that there is an error in the optical cable routing or inspection path of the difference part.
[0035] By combining and transforming the built-in functions ST_Difference(geom1 geometry,geom2 geometry), ST_Buffer(geom1 geometry,distance double_precision), and ST_Dump(geom1 geometry) of the PG database, the optical cable routing information and the inspection path information of the difference path between the optical cable routing and the inspection path can be obtained respectively. The formula is as follows:
[0036] Create a strip path surface: The ST_Buffer(geomX,R) function is used to create a buffer around a given geometry. The size of the buffer is determined by the distance parameter R.
[0037] Create a buffer for the cable route: ST_Buffer(geomA,R). This buffer represents an area of R meters on both sides of the cable route.
[0038] Create a buffer for the inspection path: ST_Buffer(geomB,R);
[0039] Calculate the difference path: ST_Difference(geomX,geomY) function is used to obtain the remaining part of geomX that intersects geomY but is not completely contained in geomY;
[0040] Calculate the second difference path: ST_Difference(geomB,ST_Buffer(geomA,R)), calculate the difference between the cable route and the inspection path buffer, and find the part of the inspection path that exceeds the cable route buffer;
[0041] Calculate the first difference path: ST_Difference(geomA,ST_Buffer(geomB,R)), calculate the difference between the cable route and the inspection path buffer, and find the part of the cable route that exceeds the inspection path buffer;
[0042] Use ST_Dump() to convert the result into a collection of geometric objects;
[0043] geomDifCable[]=ST_Dump(ST_Difference(geomA,ST_Buffer(geomB,R)));
[0044] geomDifInspect[]=ST_Dump(ST_Difference(geomB,ST_Buffer(geomA,R)));
[0045] Among them, geomA represents the path information of the optical cable routing; geomB represents the path information of the inspection path.
[0046] As an optional implementation, the first optical cable routing information may be corrected based on the on-site verification results of the optical cable laying status of the difference paths, and the correction may be performed according to the following steps: for each pair of the first difference path and the second difference path, instruct the target object to conduct an on-site verification of the optical cable laying status of the first difference path and the second difference path, and receive the verification results fed back by the target object; if the verification result indicates that the optical cable is laid on the first difference path, keep the first optical cable routing information unchanged; if the verification result indicates that the optical cable is laid on the second difference path, replace the routing information corresponding to the first difference path in the first optical cable routing information with the routing information corresponding to the second difference path.
[0047] Optionally, if the verification result indicates that the optical cable is laid on the first difference path, inspection path error information may also be sent to the target object, wherein the inspection path error information is used to prompt that an error exists in the inspection path and the second difference path in the inspection path needs to be replaced with the first difference path.
[0048] For example, the optical cable route information geomDifCable[] and the inspection path information geomDifInspect[] of the difference between the optical cable route (geomA) and the inspection trajectory information (geomB) are presented based on the geographic information system GIS map, and on-site verification is performed one by one based on the presentation results of the GIS map. If the inspection path information geomDifInspect[i] of the difference part is consistent with the actual optical cable route, the geomDifCable[i] part of the optical cable route is automatically replaced with geomDifInspect[i] to correct the optical cable route information. The correction formula is as follows: if the optical cable route information geomDifCable[i] of the difference part is consistent with the actual optical cable route, it means that the inspection trajectory is wrong, and an inspection rectification work order is automatically sent to the relevant inspection personnel to improve the inspection quality;
[0049] geomAL = ST_GeometryN(ST_Split(geomA,ST_StartPoint(geomDifCable[i])),1); / / Left routing information of abnormal optical cable routing;
[0050] geomAR = ST_GeometryN(ST_Split(geomA,ST_EndPoint(geomDifCable[i])),2); / / Right routing information of abnormal optical cable routing;
[0051] geomAN = ST_Union(ST_Union(geomAL, geomDifInspect[i]), geomAR); / / Optical cable routing corrected by geomDifInspect;
[0052] in:
[0053] The ST_StartPoint(geom) function is used to obtain the starting point of a linear graphic;
[0054] The ST_EndPoint(geom) function is used to obtain the end point of a linear graphic;
[0055] The ST_Split(line_geom,a_point) function is used to split a line line_geom into two lines according to the point a_point on the line;
[0056] The ST_GeometryN(multilinestring,N) function is used to obtain the Nth line information from multilinestring;
[0057] The ST_Union(geomA,geomB) function is used to merge geomA and geomB into one geometry.
[0058] For the second optical cable segment, optical cable duct and pole line routing information in a target area including an optical cable start point and an optical cable end point of the second optical cable segment is obtained.
[0059] Optionally, the optical cable length of the second optical cable segment is measured, and a target optical cable path is generated based on the optical cable duct and pole line routing information and the optical cable length, wherein: first, a network topology map is generated based on the optical cable duct and pole line routing information; then, a depth-first algorithm is used to determine from the network topology map a plurality of first optical cable paths connecting the optical cable start point and the optical cable end point, and a first path length of each first optical cable path is determined; then, the optical cable length is multiplied by a preset coefficient to obtain a first target path length; finally, the first optical cable path corresponding to the first path length having the smallest difference with the first target path length is determined as the target optical cable path.
[0060] For example, for a fiber optic cable with completely missing routing information, the lighting distance S of the starting and ending points of the fiber optic cable is obtained based on the lighting capability of the optical time domain reflectometer (OTDR). Considering that there are reserved optical cables at some nodes of the fiber optic cable route, the actual fiber optic cable length S ‘ = S*P (P defaults to 0.9, and the value of P depends on the type, specification, use environment, application requirements, and specific engineering requirements of the optical cable, and can be manually configured). Based on the optical cable starting point start_id, the optical cable end point end_id, and the routing information of the existing pipelines and poles, the network topology space information Routepath is created, combined with the OTDR equipment lighting and the calculated optical cable length S ‘ The built-in shortest path function pgr_dijkstra(('SELECT id, source, target, cost FROM Routepath', start_id, end_id, directed:=true) of PostGis is modified, and all possible optical cable routing paths between the starting point and the end point of the optical cable are calculated by combining the depth-first algorithm DFS, that is, multiple first optical cable paths, and a routing length closest to the optical cable length S is obtained from these optical cable routing paths. ‘ The path defaults to the actual routing information of the current optical cable, that is, the target optical cable path.
[0061] As an optional implementation, second optical cable routing information corresponding to a second optical cable segment is generated based on the point-by-point verification results of the optical cable laying status of each verification point in the target optical cable path, specifically: the target object is instructed to conduct on-site verification of the optical cable laying status of each verification point in the target optical cable path starting from the starting point of the optical cable, and the path between the starting point of the optical cable in the target optical cable path and the verification point that has passed the verification is determined to be the verified path; when no optical cable is detected at any verification point, it is determined that the verification point has failed the verification, and the path in the target optical cable path that has not completed the verification is updated based on the routing information of the optical cable duct and pole line, the length of the optical cable and the length of the path that has completed the verification in the target optical cable path, and the target object is instructed to conduct on-site verification of the optical cable laying status of each verification point in the updated path starting from the previous verification point of the verification point that failed the verification; when the verification reaches the end point of the optical cable, the second optical cable routing information corresponding to the second optical cable segment is generated based on the verified path.
[0062] Among them, when updating the paths that have not completed verification in the target optical cable path based on the routing information of the optical cable pipeline and the pole line, the optical cable length and the length of the path that has completed verification in the target optical cable path, a depth-first algorithm can be used to determine from the network topology diagram a plurality of second optical cable paths connecting the previous verification point of the verification point that failed the verification and the optical cable end point, and determine the second path length of each second optical cable path; then determine that the difference between the first target path length and the length of the path that has completed verification in the target optical cable path is the second target path length; finally, use the second optical cable path corresponding to the second path length with the smallest difference from the second target path length to replace the path that has not completed verification in the target optical cable path.
[0063] For example, the maintenance personnel use the cable patrol instrument to tap and verify the verification points in the target optical cable path point by point starting from the starting point of the optical cable. If the verification point passes, the verification point is recorded as part of the verified path. If the verification point PointN of the optical cable routing information calculated by the system is inconsistent with the on-site routing information, that is, the verification fails, the verification point PointN is removed from the network topology space information Routepath, and the previous verification point PointN-1 of the verification point PointN is used as the starting point. The optical cable end_id remains unchanged, and the second target path length S2 of the remaining second optical cable path to be verified is ′ =S ′ -S1 ′ (Where S ′ To combine the OTDR equipment lighting and the calculated optical cable path length, i.e. the first target path length, S1 ′The path length between the starting point and the verification point PointN-1, that is, the length of the path that has been verified in the target optical cable path), and finally, the second optical cable path corresponding to the second path length with the smallest difference from the second target path length is used to replace the unverified path in the target optical cable path as the new optical cable path length to jump to the second step to recalculate, and after obtaining the new optical cable routing information, continue to perform tapping verification until the verification reaches the optical cable end point end_id.
[0064] In an embodiment of the present application, the routing information storage state of the target optical cable is detected, wherein the target optical cable includes: a first optical cable segment storing the optical cable routing information and / or a second optical cable segment lacking the optical cable routing information; for the first optical cable segment, the first optical cable routing information and the inspection path information corresponding to the first optical cable segment are obtained; the difference path between the optical cable route indicated by the first optical cable routing information and the inspection path indicated by the inspection path information is determined; the first optical cable routing information is corrected according to the on-site verification result of the optical cable laying state of the difference path; for the second optical cable segment, the optical cable starting point including the second optical cable segment is obtained and the optical cable duct and pole route information in the target area of the optical cable terminal; measure the optical cable length of the second optical cable segment, and generate the target optical cable path based on the optical cable duct and pole route information and the optical cable length; generate the second optical cable route information corresponding to the second optical cable segment based on the point-by-point verification results of the optical cable laying status of each verification point in the target optical cable path, wherein, when the optical cable is not detected at any verification point, it is determined that the verification of the verification point has failed, and the unverified path in the target optical cable path is updated based on the optical cable duct and pole route information, the optical cable length and the length of the verified path in the target optical cable path. In terms of automatic correction of optical cable routes, by comparing the optical cable route with the inspection path of the maintenance personnel, the wrong optical cable route information can be automatically corrected; in terms of automatic discovery of optical cable routes, by combining the optical cable length of the optical cable segment, the routing information of the duct and pole with the path planning algorithm, combined with on-site verification, the missing optical cable route information is automatically discovered, solving the technical problems of low detection efficiency and insufficient accuracy of related optical cable route detection schemes.

[0069] A generation module 23 is used to obtain, for the second optical cable segment, the optical cable duct and pole line routing information in the target area including the optical cable starting point and the optical cable end point of the second optical cable segment; measure the optical cable length of the second optical cable segment, and generate a target optical cable path based on the optical cable duct and pole line routing information and the optical cable length; generate the second optical cable routing information corresponding to the second optical cable segment based on the point-by-point verification result of the optical cable laying status of each verification point in the target optical cable path, wherein, when no optical cable is detected at any verification point, it is determined that the verification of the verification point has failed, and the path in the target optical cable path that has not been verified is updated based on the optical cable duct and pole line routing information, the optical cable length and the length of the path in the target optical cable path that has been verified.
[0070] The functions of each module of the optical cable routing information maintenance device are described below in conjunction with a specific implementation process.
[0071] Due to various factors such as frequent splicing of existing optical cables and untimely updates of optical cable routes, there is a large difference between the existing optical path routing data and the actual optical cable routing. This application compares the optical cable routing with the inspection track of maintenance personnel, and automatically discovers and corrects erroneous optical cable routing information by analyzing the difference data between the two, thereby helping to improve the accuracy of optical cable routing data.
[0072] First, the detection module detects the routing information storage status of the target optical cable, wherein the target optical cable includes: a first optical cable segment storing the optical cable routing information and / or a second optical cable segment lacking the optical cable routing information.
[0073] For the first optical cable segment, the correction module obtains first optical cable routing information and inspection path information corresponding to the first optical cable segment.
[0074] Generally, when analyzing the routing information of the first optical cable, when the routing information of the first optical cable is completely consistent with the inspection path information of the maintenance personnel, it means that the routing information of the optical cable is accurate. However, due to the influence of various external environmental factors, it is impossible for the inspection personnel to inspect completely along the path where the optical cable is located. There must be a certain distance between the routing information of the first optical cable and the inspection path information of the maintenance personnel in space. Therefore, after obtaining the routing information of the first optical cable and the inspection path information, it is necessary to determine the difference path between the optical cable route indicated by the first optical cable routing information and the inspection path indicated by the inspection path information.
[0075] Optionally, the difference path includes a first difference path corresponding to the optical cable routing and a second difference path corresponding to the inspection path. The difference path between the optical cable routing indicated by the first optical cable routing information and the inspection path indicated by the inspection path information can be determined by the following steps: determine the first linear path corresponding to the optical cable routing indicated by the first optical cable routing information, and extend each point in the first linear path to both sides of the path by a preset distance to obtain a strip path surface; determine the second linear path corresponding to the inspection path indicated by the inspection path information; determine each path segment in the second linear path that is not located in the strip path surface as the second difference path; determine the path in each strip path surface corresponding to each segment of the second difference path in the first linear path as the first difference path.
[0076] As an optional implementation, the correction module corrects the first optical cable routing information based on the on-site verification result of the optical cable laying status of the difference path, and can be performed according to the following steps: for each pair of the first difference path and the second difference path, instruct the target object to conduct an on-site verification of the optical cable laying status of the first difference path and the second difference path, and receive the verification result fed back by the target object; if the verification result indicates that the optical cable is laid on the first difference path, keep the first optical cable routing information unchanged; if the verification result indicates that the optical cable is laid on the second difference path, replace the routing information corresponding to the first difference path in the first optical cable routing information with the routing information corresponding to the second difference path.
[0077] Optionally, if the verification result indicates that the optical cable is laid on the first difference path, inspection path error information may also be sent to the target object, wherein the inspection path error information is used to prompt that an error exists in the inspection path and the second difference path in the inspection path needs to be replaced with the first difference path.
[0078] For the second optical cable segment, the generation module obtains the optical cable duct and pole line routing information in the target area including the optical cable start point and the optical cable end point of the second optical cable segment.
[0079] Optionally, the generation module measures the optical cable length of the second optical cable segment, and generates a target optical cable path based on the optical cable duct and pole line routing information and the optical cable length, wherein: first, a network topology map is generated based on the optical cable duct and pole line routing information; then, a depth-first algorithm is used to determine from the network topology map a plurality of first optical cable paths connecting the optical cable starting point and the optical cable end point, and a first path length of each first optical cable path is determined; then, the optical cable length is multiplied by a preset coefficient to obtain a first target path length; finally, the first optical cable path corresponding to the first path length having the smallest difference with the first target path length is determined as the target optical cable path.
[0080] Optionally, the generation module generates second optical cable routing information corresponding to the second optical cable segment based on the point-by-point verification results of the optical cable laying status of each verification point in the target optical cable path, specifically: instructing the target object to conduct on-site verification of the optical cable laying status of each verification point in the target optical cable path starting from the starting point of the optical cable, and determining that the path between the starting point of the optical cable in the target optical cable path to the verification point that has passed the verification is the path that has completed the verification; when no optical cable is detected at any verification point, it is determined that the verification point has failed the verification, and the path in the target optical cable path that has not completed the verification is updated based on the optical cable pipeline and pole line routing information, the optical cable length and the length of the path that has completed the verification in the target optical cable path, and instructing the target object to conduct on-site verification of the optical cable laying status of each verification point in the updated path starting from the previous verification point of the verification point that failed the verification; when the verification reaches the end point of the optical cable, the second optical cable routing information corresponding to the second optical cable segment is generated based on the path that has completed the verification.
[0081] Among them, when updating the paths that have not completed verification in the target optical cable path based on the routing information of the optical cable pipeline and the pole line, the optical cable length and the length of the path that has completed verification in the target optical cable path, a depth-first algorithm can be used to determine from the network topology diagram a plurality of second optical cable paths connecting the previous verification point of the verification point that failed the verification and the optical cable end point, and determine the second path length of each second optical cable path; then determine that the difference between the first target path length and the length of the path that has completed verification in the target optical cable path is the second target path length; finally, use the second optical cable path corresponding to the second path length with the smallest difference from the second target path length to replace the path that has not completed verification in the target optical cable path.
