Consequently, variations from the shapes of the illustrations as a result of, for example, manufacturing processes, and / or tolerances, are to be expected.

[0064] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art.

[0065] Optical cable dumb resources are susceptible to external factors such as construction, natural disasters, and have the characteristics of many faults and difficult monitoring. In the existing optical cable fault positioning scheme, it is not possible to effectively monitor the optical cable fault in a systematic manner in real time online, resulting in greater difficulty in maintaining the optical cable.

[0066] When the optical cable resource is accurate, for example, in the case of backbone transmission, the optical cable state can be presented through the optical cable dumb resource geographic information system (GIS) layer, so as to perform online real-time detection on important lines. At this time, once an optical cable fault occurs, the network management system can be used for real-time alarm reporting. However, when the optical cable resource is inaccurate, for example, in the case of local transmission, it is not possible to quickly and effectively locate the optical cable fault point through the network management system, exchange management system, and the like.

[0067] The existing optical cable fault positioning method can be divided into network reasons, configuration reasons and physical reasons, and usually needs to arrange maintenance personnel to check the OTDR equipment on site, or to patrol the hidden danger point along the optical cable laying line. For example, when the communication optical cable is broken by the construction personnel repairing the road, the maintenance personnel diagnoses the optical cable fault based on the test function of the OTN (Optical Transport Network) optical transmission equipment and the OTDR equipment. Since the OTN devices are generally connected directly in the form of bare fiber within the local transmission range, in this case, the OTDR cannot effectively locate the optical cable fault, and the maintenance personnel need to further test the fiber on the access room and need to visit the optical cable laying section. The optical cable laying line is as long as several kilometers, and the troubleshooting efficiency is low.

[0068] Therefore, the existing optical cable fault positioning method not only has high artificial participation, but also has long maintenance time and low overall troubleshooting efficiency, which cannot meet the increasing needs of optical cable construction.

[0069] Therefore, the present application embodiment provides an optical cable fault positioning method, which determines the topology structure of the physical site by the position information of the physical site in the transport network and the association relationship between the physical sites, so that after obtaining the fault alarm information, the corresponding fault topology line can be determined in the topology structure, and the optical cable laying prediction area corresponding to the fault topology line is determined. Finally, the optical cable fault prediction area is determined through the determined optical cable laying prediction area, so as to predict the possible location of the optical cable fault positioning in the case of unclear optical cable resources, which provides a reference for professional personnel and local maintenance personnel, effectively shortens the fault positioning time, and realizes the rapid positioning of the optical cable fault.

[0070] In a first aspect, the present application embodiment provides an optical cable fault positioning method.

[0071] Figure 1 The flowchart of the optical cable fault positioning method provided by the present application embodiment is shown in Figure 1 The method comprises:

[0072] Step S110: determining the topology structure of the physical site according to the position information of the physical site in the transport network and the association relationship between the physical sites, wherein the association relationship between the physical sites is determined by the network relationship between the network elements corresponding to the physical sites.

[0073] The transport network refers to an optical transmission network based on optical cable resources for data transmission.

[0074] For example, the transport network can be a Universal Transport Network (UTN), a Packet Transport Network (PTN), etc.

[0075] In some alternative implementations, a physical site is a site with an actual equipment room deployment within the transport network architecture. The location information of the physical site is used to identify its actual location, such as its latitude and longitude.

[0076] In some optional implementations, each physical site can correspond to multiple network elements to facilitate data transfer between physical sites.

[0077] Among them, network elements are network nodes that transmit data in the transmission network. Under different network layer architectures of the transmission network, there are corresponding network elements.

[0078] For example, the network architecture of a transport network (UTN) includes an access layer, an aggregation layer, and a core layer. Correspondingly, network elements can be further divided into access layer network elements, aggregation layer network elements, and core layer network elements.

[0079] In some optional implementations, the association between physical sites can be determined based on the network relationship between network elements corresponding to different physical sites.

[0080] It should be noted that as long as data transmission can occur between any two network elements—for example, if network element 1 sends data to port B of network element 2 via port A—a network relationship exists between these two network elements. Therefore, the network relationship between network elements can be used to determine the association between the physical sites to which the network elements belong.

[0081] Specifically, when there are network relationships between network elements, it is determined that there are also relationships between the physical sites to which the network elements belong.

[0082] For example, if network element A and network element B have a network relationship, then physical site 1 to which network element A belongs and physical site 2 to which network element B belongs are associated.

[0083] It should also be noted that since network elements can be divided into various types, in practical applications, the appropriate type of network element can be selected to determine the relationship between physical sites.

[0084] For example, the association relationship of a physical site is determined solely based on the network relationship of the access layer network element (i.e., the base station-side network element), and this embodiment of the invention does not impose any limitations on this.

[0085] In some optional implementations, the topology of the physical sites can be determined based on the location information of the physical sites and the association relationship between the physical sites.

[0086] Exemplarily, the topology nodes corresponding to the physical sites can be established on a map according to the location information of the physical sites, and the topology lines between the topology nodes can be established according to the association relationship between the physical sites, so as to construct the topology of the physical sites.

[0087] Step S120: determining at least one fault topology line in the topology in response to the acquired fault alarm information.

[0088] The fault alarm information is alarm data generated when the optical cable fails. The fault alarm information has different alarm types.

[0089] Exemplarily, the alarm types of the fault alarm information can include dynamic ring alarm, IPRAN (Internet Protocol Radio Access Network) alarm, transmission alarm, tower alarm, wireless alarm, etc.

[0090] For different alarm types, the content contained in the fault alarm information is different. For example, the fault alarm information can contain alarm time, alarm type, alarm title, fault physical site information, fault device information, fault network element information, etc.

[0091] In some optional implementations, after the fault alarm information is acquired, the fault topology line corresponding to the fault alarm information can be determined in the topology by analyzing the fault alarm information.

[0092] Specifically, the physical site corresponding to the fault alarm information is determined according to the association relationship between the alarm information and the physical site by extracting the physical site-related alarm information in the fault alarm information. The topology point corresponding to the physical site is determined in the topology, and the topology line associated with the topology point is taken as the fault topology line.

[0093] Exemplarily, the physical site to which the fault device belongs can be determined according to the fault device information in the fault alarm information by extracting the fault device information, so as to determine the topology point corresponding to the physical site in the topology, and take the topology line associated with the topology point as the fault topology line. By determining the fault topology line corresponding to the fault alarm information in the topology, the association mapping of the fault alarm information in the topology is effectively realized.

[0094] After the fault topology line is determined, the fault topology line can be displayed by highlighting or adjusting the color of the topology line, so that the user can intuitively see the network element, physical site, etc. that currently generates the alarm in the topology.

[0095] Step S130: determining the cable laying prediction area of each fault topology line according to a preset area demarcation manner.

[0096] The preset area demarcation manner can include preset area size, preset area position, preset area shape, and the like, and embodiments of the present application do not limit the same.

[0097] Through the preset area demarcation manner, the cable laying prediction area corresponding to the fault topology line can be determined. The cable laying prediction area refers to an area in which the cable corresponding to the fault topology line is likely to be laid. This is because, in the actual cable laying process, the cable is often not laid in a straight line between two endpoints due to external factors such as geographical conditions, and thus the cable laying prediction area can represent an area in which the cable is likely to be laid.

[0098] Figure 2 A schematic diagram of a cable fault positioning method provided by an embodiment of the present application is shown in FIG. 1, in which the curve is an actual cable laying line corresponding to the fault topology line, and the elliptical area is a cable laying prediction area corresponding to the fault topology line. Figure 2

[0099] Step S140: determining the cable fault prediction area according to the cable laying prediction area of at least one fault topology line.

[0100] The cable fault prediction area refers to a prediction area in which a cable fault is likely to occur. By determining the cable fault prediction area, the area in which the cable fault corresponding to the fault alarm information is likely to exist can be located for the reference of the maintenance personnel.

[0101] In some optional implementations, the cable fault prediction area can be determined according to the number of fault topology lines.

[0102] For example, when there is only one fault topology line, the cable laying prediction area corresponding to the fault topology line can be determined as the cable fault area.

[0103] Specifically, when there is only one fault topology line, the cable corresponding to the fault topology line is likely to have a fault, and thus the cable laying prediction area corresponding to the fault topology line can be determined as the cable fault area.

[0104] When there are multiple fault topology lines in the actual fault state, the cable laying prediction areas of the multiple fault topology lines can be analyzed in association, and the cable fault prediction area corresponding to the fault topology line can be determined according to the analysis result.

[0105] In some optional implementations, the association analysis includes intersection analysis of the cable laying prediction areas corresponding to the multiple fault topology lines.​

[0106] Correspondingly, the optical cable fault prediction area is determined according to the optical cable laying prediction areas of the at least one fault topology line, including: in the case that the number of fault topology lines is multiple, determining a first intersection area between the optical cable laying prediction areas corresponding to the fault topology lines; and determining the first intersection area as the optical cable fault prediction area corresponding to the multiple fault topology lines.

[0107] In the case of optical cable fault in a real scene, multiple fault topology lines may occur in the topology structure. If two fault topology lines are in a relatively close geographical range, there may be an intersection area between the optical cable laying prediction areas corresponding to the fault topology lines.

[0108] By judging the intersection area between the optical cable laying prediction areas corresponding to the fault topology lines, the optical cable fault prediction area corresponding to the multiple fault topology lines can be further determined.

[0109] It should be noted that in the case that there is no intersection area between the optical cable laying prediction areas of the multiple fault topology lines, the intersection judgment range can be further expanded by adjusting the size of the optical cable laying prediction area of the fault topology line. The optical cable laying prediction area corresponding to the fault topology line can also be used as the optical cable fault prediction area corresponding to the fault topology line, and the embodiments of the present application do not limit this.

[0110] Figure 3 A schematic diagram of an optical cable fault positioning method provided by the embodiments of the present application is shown in FIG. 1. Figure 3

[0111] In the topology structure, there are fault topology line A and fault topology line B, and optical cable laying prediction area A and optical cable laying prediction area B are the optical cable laying prediction areas corresponding to fault topology line A and fault topology line B respectively.

[0112] There is an intersection area between optical cable laying prediction area A and optical cable laying prediction area B, and the intersection area is the optical cable fault prediction area corresponding to fault topology line A and fault topology line B.

[0113] The reason for performing intersection analysis on the optical cable laying prediction areas corresponding to the fault topology lines is mainly that relatively close fault topology lines may be caused by the same optical cable fault. Therefore, if there is an intersection between the optical cable laying prediction areas corresponding to multiple fault topology lines, the fault position is very likely to be located in the area corresponding to the intersection. Therefore, in the case that there are multiple fault topology lines, the intersection area between the optical cable laying prediction areas corresponding to the fault topology lines can be determined as the optical cable fault prediction area, which further reduces the range of the optical cable fault prediction area, thereby improving the effectiveness of the optical cable fault positioning in a complex scene.

[0114] ​In the embodiment of the present application, the topology of the physical sites is determined by transmitting the location information of the physical sites and the association relationship between the physical sites, so that after the fault alarm information is acquired, the corresponding fault topology line can be determined in the topology structure, and the optical cable laying prediction area corresponding to the fault topology line is determined, finally, the optical cable fault prediction area is determined through the determined optical cable laying prediction area, and the rapid positioning of the optical cable fault is realized.

[0115] In some optional implementation, when the topology of the physical sites is constructed, due to the complex network relationship involved between different network elements, if the network relationship of the network elements is mapped to the association relationship between the physical sites, the number of topology lines in the topology structure will be numerous, which affects the rapid positioning, therefore, the association relationship between the physical sites can be determined only through the network relationship between the network elements in the loop.

[0116] Correspondingly, the network relationship between the network elements corresponding to the physical sites can be acquired through the loop account information.

[0117] The loop account information is the network element loop information composed of multiple network elements. The network elements in the loop are the network elements with higher importance in the actual application scenario.

[0118] For a network element loop, when the communication state between a pair of network elements in the network element loop changes, the overall communication state of the network element loop will not be affected. By acquiring only the network relationship between the network elements in the loop account, the complexity of the topology structure can be effectively reduced.

[0119] Further, determining the topology of the physical sites according to the location information of the physical sites in the transmission network and the association relationship between the physical sites can include the following steps:

[0120] First, according to the location information of the physical sites, the topology nodes corresponding to the physical sites in the topology structure are established on the GIS map. For example, according to the longitude and latitude information of the physical sites, the topology nodes of the physical sites are established on the corresponding longitude and latitude positions on the GIS map.

[0121] Then, according to the association relationship between the physical sites, the association relationship of the topology nodes corresponding to the physical sites is determined.

[0122] In the case where there is an association relationship between the physical sites, there is an association relationship between the topology nodes corresponding to the physical sites.

[0123] Finally, according to the topology nodes corresponding to the physical sites and the association relationship of the topology nodes corresponding to the physical sites, the topology of the physical sites is determined.

[0124] When there is an association relationship between the topology nodes corresponding to the physical sites, a topology line is established between the corresponding topology nodes, and after the construction of the topology nodes corresponding to the physical sites and the topology lines between the topology nodes are completed, a complete topology structure of the physical site is formed.

[0125] In the embodiment of the application, the association relationship between the network elements corresponding to the physical sites is obtained through the loop account information, and the association relationship between the physical sites is determined according to the association relationship between the network elements, so that the topology structure is constructed according to the position information of the physical sites and the association relationship, the logical mapping on the GIS map is realized, the complexity of the topology structure is effectively reduced, and the positioning efficiency of the optical cable fault is improved.

[0126] It should be noted that, since the alarm identification types involved in the fault alarm information are different, in order to facilitate the association and matching of the fault alarm information and the topology structure, the topology nodes in the topology structure can be divided into corresponding topology sub-nodes according to the alarm identification types, so that the topology nodes are quickly matched in the topology structure under different alarm identification types.

[0127] In some optional implementation manners, the topology nodes can include logical site topology sub-nodes corresponding to the physical sites and network element topology sub-nodes corresponding to the physical sites.

[0128] The logical site is a logical device related to the physical site, for example, a network device related to data transmission, and one physical site can correspond to multiple logical sites. For each logical site, there is a logical site topology sub-node corresponding to the logical site in the topology structure.

[0129] Similarly, for each network element subordinate to the physical site, there is a network element topology sub-node corresponding to the network element in the topology structure.

[0130] It should be noted that the physical site, the logical site and the network element can establish the belonging relationship through the identification information of the physical site. For example, the physical site number is 001, and the logical site A and the network element A can be set to belong to the 001 physical site.

[0131] Similarly, through the belonging relationship of the physical site, the logical site and the network element, the belonging relationship between the topology nodes, the logical site topology sub-nodes and the network element topology sub-nodes can be established.

[0132] It should be noted that when the topology nodes are constructed, adaptive construction can be performed according to the display requirements of the topology structure.

[0133] Exemplarily, according to the location information of the physical site, the logical site topology sub-node and the network element topology sub-node can be plotted at the same location on the GIS map, or the logical site topology sub-node and the network element topology sub-node can be established in a correlation mapping manner, that is, the topology sub-node is not plotted on the GIS map, and only the relevant information of the topology sub-node is correlated to the corresponding topology node, so as to facilitate the display of the topology structure.

[0134] Further, in response to the obtained fault alarm information, determining at least one fault topology line in the topology structure can include the following steps:

[0135] First, at least one of the fault physical site information, the fault logical site information and the fault network element information in the fault alarm information is obtained.

[0136] Secondly, in the case of obtaining the fault physical site information, the topology node corresponding to the physical site information is determined, and the topology line associated with the topology node is determined as the fault topology line corresponding to the fault alarm information.

[0137] Wherein, in the case of obtaining the fault physical site information, the topology node corresponding to the fault physical site can be directly determined according to the identification information of the fault physical site, such as the physical site number, so as to determine the topology line associated with the topology node as the corresponding fault topology line.

[0138] Then, in the case of obtaining the fault logical site information, the logical site topology sub-node corresponding to the fault logical site information is determined, and the topology node to which the logical site topology sub-node belongs is determined according to the affiliation relationship between the logical site topology sub-node and the topology node, and the topology line associated with the topology node is determined as the fault topology line corresponding to the fault alarm information.

[0139] It should be noted that the corresponding logical site topology sub-node can be determined in the topology structure according to the identification information in the fault logical site information.

[0140] Exemplarily, according to the logical site number in the fault logical site information, the logical site topology sub-node is determined, and the topology node to which the logical site topology sub-node belongs is further determined.

[0141] Finally, in the case of obtaining the fault network element information, the network element topology sub-node corresponding to the fault network element information is determined, and the topology node to which the network element topology sub-node belongs is determined according to the affiliation relationship between the network element topology sub-node and the topology node, and the topology line associated with the topology node is determined as the fault topology line corresponding to the fault alarm information.

[0142] It should be noted that the corresponding network element topology sub-node can be determined in the topology structure according to the identification information in the fault network element information.

[0143] Exemplarily, according to the network element number in the fault network element information, a corresponding network element topology sub-node is determined, and based on the belonging relationship between the network element topology sub-node and the topology node, a topology node to which the network element topology sub-node belongs is determined.

[0144] In the embodiment of the application, by dividing the topology nodes into different types of topology sub-nodes, corresponding to different types of fault alarm information, when different fault alarm information is obtained, the association and matching of the fault alarm information and the topology structure can be more comprehensively and effectively realized, and the effectiveness of the optical cable fault positioning is improved.

[0145] In some optional implementation manners, the topology structure is arranged on a preset GIS map, and the GIS map further includes a preset target area, after the optical cable fault prediction area is determined, the method further includes: determining a second intersection area between the optical cable fault prediction area and the target area; and updating the optical cable fault prediction area to the second intersection area.

[0146] It should be noted that by arranging the topology structure on the GIS map, the physical sites and their associated relationships, and the fault topology line corresponding to the fault alarm information can be intuitively presented on the GIS map.

[0147] The preset target area refers to a set key area in which the optical cable fault is likely to occur, for example, an optical cable guard area, a construction area, etc.

[0148] After the work order information is obtained, the corresponding geographic position information such as the latitude and longitude information in the optical cable guard area, the construction area, etc. contained in the work order information is obtained, so as to mark the corresponding target point on the GIS map, and the area surrounded by the lines of the multiple target points is the preset target area.

[0149] In the case of the optical cable fault, if the target area and the optical cable fault prediction area have an intersection area, it can be predicted that the construction behavior in the target area causes the optical cable fault, and the optical cable fault prediction area is updated to the above intersection area. Therefore, the local maintenance personnel can perform correlation analysis according to the optical cable fault prediction area, the alarm information, and the optical cable line laying data to perform accurate positioning and cause analysis of the optical cable fault.

[0150] Figure 4 The schematic diagram of the optical cable fault positioning method provided by the embodiment of the application is shown in FIG. 1. Figure 4

[0151] ​The intersection region between the cable laying prediction region A corresponding to the fault topology line A and the cable laying prediction region B corresponding to the fault topology line B is the original optical cable fault prediction region. After judging that the target region and the original optical cable fault prediction region have an intersection region, the intersection region is updated as a new optical cable fault prediction region.

[0152] In the embodiment of the application, in the case that the optical cable fault prediction region and the target region have an intersection region, the optical cable fault prediction region is updated as the intersection region, which further narrows the range of the optical cable fault prediction region and locates it to a certain region or a certain road for reference by local maintenance personnel, thereby further improving the efficiency of optical cable fault positioning.

[0153] With the increase of the optical cable maintenance region, a large number of fault topology lines may exist in the topology structure, which causes a sharp increase in the number of intersection region judgments, thereby affecting the efficiency of optical cable fault positioning.

[0154] For example, in the case of N fault topology lines, if the intersection between each two fault topology lines is judged, (N-1) × (N-2) / 2 intersection judgments are required. With the increase of the number of fault topology lines, the number of intersection judgments increases sharply. When N is 10000, the number of intersection judgments can reach 9999 × 9998 / 2 = 49990001.

[0155] If the number of intersection judgments is too large, the server will have a very high computing power requirement, which will affect the actual application.

[0156] In some optional implementation manners, the step of determining the intersection region between the cable laying prediction regions corresponding to the fault topology lines can be performed only on the fault topology lines within a preset time range.

[0157] Correspondingly, before determining the first intersection region between the cable laying prediction regions corresponding to the fault topology lines, the method further includes: determining, according to the fault alarm information corresponding to the fault topology lines, alarm times corresponding to the fault topology lines; and in response to the alarm times corresponding to the plurality of fault topology lines satisfying a preset time range, performing the step of determining the first intersection region between the cable laying prediction regions corresponding to the fault topology lines.

[0158] The preset time range can be adaptively set according to actual fault alarm conditions. For example, the preset time range can be set to 1 minute, 3 minutes, 5 minutes, etc., and the embodiment of the application does not limit this.

[0159] It should be noted that the smaller the difference between the alarm times corresponding to two fault topology lines, the higher the relevance of the fault alarm information corresponding to the two fault topology lines.

[0160] For example, when the alarm time difference is less than 10 seconds, the fault alarm information corresponding to the two fault topology lines can be basically attributed to the same optical cable fault. For another example, when the alarm time difference is greater than 10 minutes, the correlation of the fault alarm information corresponding to the two fault topology lines is low.

[0161] In the embodiment of the application, the intersection region between the optical cable laying prediction regions corresponding to the fault topology lines is determined only within the preset time range, which effectively reduces the number of determinations of the intersection region, improves the optical cable fault positioning efficiency, and effectively improves the accuracy of optical cable fault positioning.

[0162] In some optional implementation manners, the intersection relationship of the topology lines can be stored in an intersection relationship table in advance, so that the intersection region between the optical cable laying prediction regions corresponding to the fault topology lines can be directly determined through the intersection relationship table, and real-time calculation of each intersection region is avoided.

[0163] In some optional implementation manners, the step of determining the intersection region between the optical cable laying prediction regions corresponding to the fault topology lines can also be performed on the fault topology lines within a preset geographical region range.

[0164] Correspondingly, before determining the first intersection region between the optical cable laying prediction regions corresponding to the fault topology lines, the method further includes: determining whether the position information of the physical site corresponding to the fault topology lines meets the preset geographical region range; and if yes, performing the step of determining the first intersection region between the optical cable laying prediction regions corresponding to the fault topology lines.

[0165] It should be noted that the preset geographical region range can be adaptively set according to actual application.

[0166] For example, in actual production line design, a network element loop across cities will not occur, and therefore, in the topology structure, the topology line corresponding to the network element loop will not cross cities, so that the preset geographical region range can be limited within the same city range to reduce the number of intersection determinations.

[0167] Illustratively, assuming that the number of topology lines in the topology structure is 10,000, if the intersection region is determined in advance for the optical cable laying regions corresponding to each pair of topology lines, about 50 million determinations are required. After the preset geographical region range is set, the number of topology lines in a city can be only 500, and the number of intersection determinations corresponding thereto is only about 125,000, thereby effectively reducing the number of intersection determinations.

[0168] In the embodiment of the application, the intersection region between the optical cable laying prediction regions corresponding to the fault topology lines is determined only within the preset geographical region range, which can effectively reduce the number of determinations of the intersection region and improve the optical cable fault positioning efficiency.

[0169] In some optional implementations, the cable laying prediction area corresponding to each fault topology line is determined according to a preset area delineation manner, including: taking a center point of the fault topology line as a center point of the cable laying prediction area corresponding to the fault topology line; determining a range of the cable laying prediction area according to a length of the fault topology line; and determining the cable laying prediction area corresponding to the fault topology line on the GIS map according to the center point of the cable laying prediction area, the range of the cable laying prediction area, and a preset area shape of the cable laying prediction area.

[0170] It should be noted that the preset area shape can be adaptively set according to the actual cable laying state.

[0171] For example, in an actual scenario, a cable laying line is generally between two physical sites, and is preferentially laid underground beside a road. Generally, the vertical laying length of the cable is generally shorter than the distance between the two physical sites.

[0172] Therefore, the preset area shape can be set according to the horizontal and vertical distribution of the cable laying line, for example, the preset area shape is set as an ellipse or a rectangle.

[0173] Further, the range of the cable laying prediction area can be determined according to the length of the fault topology line, so that the cable laying prediction area can contain the fault topology line and the actual cable laying line.

[0174] According to the range of the cable laying prediction area and the preset area shape of the cable laying prediction area, the cable laying prediction area corresponding to the fault topology line on the GIS map can be determined, thereby improving the prediction accuracy of the cable laying prediction area corresponding to the fault topology line.

[0175] In some optional implementations, the preset area shape is an ellipse, and the range of the cable laying prediction area includes a long radius and a short radius of the cable laying prediction area; the range of the cable laying prediction area is determined according to the length of the fault topology line, including the following steps:

[0176] First, the long radius of the cable laying prediction area is determined according to the length of the fault topology line and a preset long radius multiple parameter.

[0177] The long radius multiple parameter is used to dynamically adjust the long radius of the cable laying prediction area. The long radius of the cable laying prediction area cannot exceed the product of half of the length of the fault topology line and the long radius multiple parameter.

[0178] Then, the short radius of the cable laying prediction area is determined according to the length of the fault topology line and a preset short radius multiple parameter.

[0179] The short radius multiple parameter is used to dynamically adjust the short radius of the optical cable laying prediction area. The short radius of the optical cable laying prediction area cannot exceed the product of half of the length of the fault topology line and the short radius multiple parameter.

[0180] For example, assuming that the coordinates of topology node A of a topology line are (Xa, Ya) and the coordinates of topology node B are (Xb, Yb), the distance between the two topology nodes can be calculated according to the two coordinates, which is assumed to be M meters. Then the coordinates of the center point C of the topology line are (Xc, Yc) = ((Xa+Xb) / 2, (Ya+Yb) / 2).

[0181] The long radius LR of the ellipse is defined to be greater than half of the length of the topology line, that is, the long radius LR is greater than M / 2. Assuming that the long radius multiple parameter is a, there is M / 2 < LR < M / 2*a.

[0182] The short radius SR of the ellipse is defined to be less than half of the length of the topology line, that is, the short radius SR is less than M / 2. Assuming that the short radius multiple parameter is b, there is 0 < SR < M / 2.

[0183] It should be noted that the long radius multiple parameter and the short radius multiple parameter can be dynamically adjusted, so as to dynamically adjust the optical cable laying prediction area. When both parameters are increased, the corresponding optical cable laying prediction area is also expanded.

[0184] Only when the long radius multiple parameter and the short radius multiple parameter are set in a reasonable range of values, the accuracy of the optical cable fault prediction area can be improved.

[0185] For example, for the long radius multiple parameter a, there is generally no case of a >= 2 in the value range. In the actual construction process, the optical cable line will not be laid too far along the physical site connection line direction. For the short radius multiple parameter b, there is generally no case of b >= 1 in the value range. In the actual construction process, the optical cable line will not be laid too far along the perpendicular direction of the physical site connection line.

[0186] It should be further noted that when the optical cable laying prediction area corresponding to the fault topology line is plotted on the GIS map, the center coordinates, the long radius, the short radius of the ellipse, and the included angle of the fault topology line can be used for graphical plotting.

[0187] In some optional implementations, considering the influence of the radian on the coordinate offset, the center coordinates of the ellipse can be determined according to the following manner: converting the longitude and latitude coordinates of the topology nodes corresponding to the fault topology line into coordinate values in the rectangular coordinate system; determining the corresponding coordinate values of the center point of the fault topology line in the rectangular coordinate system according to the coordinate values in the rectangular coordinate system; and converting the coordinate values into longitude and latitude coordinates, so as to take the longitude and latitude coordinates as the center coordinates of the ellipse on the GIS map.

[0188] wherein the included angle of the fault topology line is an included angle formed by the fault topology line and the X axis in a mathematical coordinate system.

[0189] In the case of the included angle being 0°, assuming that the distance of the fault topology line is M / 2, the long radius LR is valued as M / 2<LR<M / 2*a, wherein a is a long radius multiple parameter. The short radius SR is valued as 0<SR<b<M / 2, wherein b is a short radius multiple parameter.

[0190] In the case of the included angle being greater than 0°, the long radius LR is valued as M / 2*a, that is,

[0191]

[0192] wherein (Xa, Ya) and (Xb, Yb) are coordinate values of topology nodes corresponding to the fault topology line.

[0193] Correspondingly, the short radius SR is valued as M / 2÷b, that is,

[0194]

[0195] After the related parameters are determined, the drawing of the optical cable laying prediction area can be realized by calling an ellipse drawing function, and the intersection area between the optical cable laying prediction areas corresponding to the fault topology lines can be determined by calling an ellipse intersection judgment function.

[0196] In the embodiment of the application, by setting the preset area as an ellipse and determining the range of the optical cable laying prediction area based on the long radius multiple parameter and the short radius multiple parameter, the actual optical cable laying line is effectively covered, and the accuracy of the optical cable laying prediction area is improved.

[0197] Figure 5 A flowchart of an optical cable fault positioning method provided in the embodiment of the application is shown in FIG. 1. Figure 5 As shown in FIG. 1, the method comprises the following steps.

[0198] Step S510: determining a topology structure of physical sites according to position information of the physical sites and an association relationship between the physical sites, wherein the association relationship between the physical sites is determined by a network relationship between network elements corresponding to the physical sites.

[0199] Step S520: determining at least one fault topology line in the topology structure in response to the obtained fault alarm information.

[0200] Step S530: determining optical cable laying prediction areas of each fault topology line according to a preset area demarcation manner.

[0203] Step S560: determining a second intersection region between the cable fault prediction region and the target region.

[0204] Step S570: updating the cable fault prediction region as the second intersection region.
