Description

Technical Field

[0001] The present invention relates to the technical field of transmission network resource management, and specifically provides an optical cable system construction and fault search method and system. Background Art

[0002] As network structures become increasingly complex, operators rely more on network resource management systems to clearly count resource conditions for services such as optical path opening. Optical cable systems are an important part of transmission networks.

[0003] When the system is in use, it is often accompanied by on-site optical cable system failures. Existing optical cable system construction methods mostly focus on physical optical cable system construction and troubleshooting processes, relying on on-site implementation and maintenance personnel to troubleshoot and discover faults. The troubleshooting cycle is long and it is difficult to quickly locate the actual fault location of the optical cable section.

[0004] There is also a method to completely abstract the optical cable system into a topology diagram for analysis, and upload the optical cable segment fault data in real time through the optical cable sensor. Although the fault detection of the optical cable segment is achieved, the optical cable system fault information caused by the bearing point and the equipment itself is ignored, and the lack of actual spatial location makes it difficult for maintenance personnel to directly locate.

[0005] In addition, operators usually analyze the optical path conditions and need to be able to quickly provide a fault-free optical cable path with a specified start and end point. Summary of the invention

[0006] The present invention aims at the above-mentioned deficiencies of the prior art and provides a highly practical optical cable system construction and fault search method.

[0007] A further technical task of the present invention is to provide a reasonably designed, safe and applicable optical cable system construction and fault search system.

[0008] The technical solution adopted by the present invention to solve the technical problem is:

[0009] A method for constructing an optical cable system and searching for faults comprises the following steps:

[0010] S1, optical cable resource acquisition module completes space resource acquisition and construction;

[0011] S2. Optical cable system building module design optical equipment panel diagram, including the equipment's ODM module, tray and terminal and panel arrangement;

[0012] S3. The optical cable fault diagnosis module calls the optical cable path search algorithm to search the specified optical cable system, troubleshoot the optical cable system faults and render them into visual data.

[0013] Furthermore, in step S1, the optical cable resource collection module performs spatial resource GIS collection and resource construction, and then completes the GIS collection and resource construction of optical equipment and bearer points based on the spatial resources, and completes the spatial GIS collection and resource construction of the bearer section with the spatial resources or optical equipment as the starting points of end A and end Z.

[0014] Further, in step S2, the local optical cable connected to the optical device end and its opposite end device are selected to complete the panel fiber core termination, racking or removal between the two devices; the local optical cable connected to the device is selected to perform welding or removal of the optical cable.

[0015] Furthermore, the ODM module includes several trays, each tray includes multiple terminals, and then the optical cables are selected in turn, and the optical cable cores are terminated or fused. The optical cable cores are terminated at the devices on both sides and fused several times in the middle.

[0016] Furthermore, the cable segment and the two ends of the fiber core are defined as end A and end Z respectively. The end Z of one cable segment is connected to the end A of the next cable segment in sequence. A recursive method is used to search for faults in the specified cable segment. The search steps are as follows:

[0017] (1) Obtain the fiber core group owned by the starting optical cable segment;

[0018] (2) Determine the status of each fiber core and the fiber core segment to which it belongs. If the terminal at the A or Z end of the fiber core is missing or abnormal, record the fault information;

[0019] (3) Query all next-hop unterminated fiber core groups to which the fiber core ends A and Z of the optical cable segment are connected;

[0020] (4) If the number of fiber core groups connected to ends A and Z is inconsistent with the number of unterminated fiber core groups found at the next hop, it indicates that the connection is abnormal and the fault information is recorded;

[0021] (5) Determine the status of the next-hop fiber core at the fiber core A end and the fiber core Z end and the optical cable segment to which the fiber core belongs. If the terminal at the fiber core A end or the fiber core Z end is missing or in an abnormal state, record the fault information.

[0022] (6) The fiber core group at the next hop of the fiber core A and Z ends is regarded as the fiber core group of the starting optical cable segment, and steps (1) to (6) are performed to both ends respectively until the number of the fiber core groups at the next hop is 0.

[0023] An optical cable system construction and fault search system, comprising an optical cable resource acquisition module, an optical cable system construction module and an optical cable fault diagnosis module;

[0024] The optical cable resource acquisition module is used to complete the space resource acquisition and construction;

[0025] The optical cable system building module is used to design the panel diagram of the optical equipment, including the ODM module, tray and terminal and panel arrangement of the equipment;

[0026] The optical cable fault diagnosis module is used to call the optical cable path search algorithm to search the specified optical cable system, troubleshoot the optical cable system faults and render them into visual data.

[0027] Furthermore, the optical cable resource collection module is used to perform spatial resource GIS collection and resource construction, and then complete the GIS collection and resource construction of optical equipment and bearer points based on the spatial resources, and complete the spatial GIS collection and resource construction of the bearer section with spatial resources or optical equipment as the starting points of end A and end Z.

[0028] Furthermore, in the optical cable system construction module, the local optical cable connected to the optical device end and its opposite end device are selected to complete the panel fiber core termination, racking or removal between the two devices; the local optical cable connected to the device is selected to weld or remove the optical cable.

[0029] Furthermore, the ODM module includes several trays, each tray includes multiple terminals, and then the optical cables are selected in turn, and the optical cable cores are terminated or fused. The optical cable cores are terminated at the devices on both sides and fused several times in the middle.

[0030] Furthermore, define the cable segment and the two ends of the fiber core as end A and end Z respectively. The end Z of one cable segment is connected to the end A of the next cable segment in sequence. Use a recursive method to search for faults in the specified cable segment. The search steps are as follows:

[0031] (1) Obtain the fiber core group owned by the starting optical cable segment;

[0032] (2) Determine the status of each fiber core and the fiber core segment to which it belongs. If the terminal at the A or Z end of the fiber core is missing or abnormal, record the fault information;

[0033] (3) Query all next-hop unterminated fiber core groups to which the fiber core ends A and Z of the optical cable segment are connected;

[0034] (4) If the number of fiber core groups connected to ends A and Z is inconsistent with the number of unterminated fiber core groups found at the next hop, it indicates that the connection is abnormal and the fault information is recorded;

[0035] (5) Determine the status of the next-hop fiber core at the fiber core A end and the fiber core Z end and the optical cable segment to which the fiber core belongs. If the terminal at the fiber core A end or the fiber core Z end is missing or in an abnormal state, record the fault information.

[0036] (6) The fiber core group at the next hop of the fiber core A and Z ends is regarded as the fiber core group of the starting optical cable segment, and steps (1) to (6) are performed to both ends respectively until the number of the fiber core groups at the next hop is 0.

[0037] Compared with the prior art, the optical cable system construction and fault search method and system of the present invention have the following outstanding beneficial effects:

[0038] The present invention significantly improves the planning and management efficiency of the optical cable system through a systematic resource collection and construction process. This method not only realizes the comprehensive and accurate recording of key resources such as optical cables, optical equipment and bearing points, but also ensures the visualization of spatial resources and the accuracy of geographical location through the application of GIS system, providing powerful data support for the planning, construction and maintenance of the optical cable system.

[0039] The present invention realizes the construction of optical cable system by combining the termination and fusion processing of optical cable core with the optical equipment panel diagram. In this process, the detailed record of optical cable and fiber core not only includes basic physical information, but also covers key attributes such as service level, life cycle status, and qualification, providing a rich data foundation for subsequent operation and maintenance management.

[0040] The recursive optical cable fault search algorithm introduced in the present invention can quickly and accurately locate the fault point in the optical cable system and present the fault information comprehensively. This function greatly improves the efficiency and accuracy of fault detection, reduces the service interruption time caused by faults, and improves the reliability of the network and user satisfaction.

[0041] In addition, the present invention also has a real-time monitoring and updating mechanism, which can ensure the timeliness of the status of optical cables and fiber cores, and provide the latest fault information for operation and maintenance personnel. At the same time, the graphical interface display method makes the optical cable system construction results and fault search results more intuitive and easy to understand, which is convenient for operation and maintenance personnel to quickly understand and deal with related problems.

[0048] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] A best embodiment is given below:

[0050] like Figure 1 As shown, a method for constructing an optical cable system and searching for faults in this embodiment has the following steps:

[0051] S1, optical cable resource acquisition module completes space resource acquisition and construction;

[0052] In the optical cable resource acquisition module, the spatial resource GIS acquisition and resource construction of spatial resources (sites, network resource points, business areas) are carried out, and then the GIS acquisition and resource construction of optical equipment (fiber distribution boxes, optical junction boxes) and bearing points (manholes, electric poles, benchmarks, support points) are completed according to the spatial resources. The spatial GIS acquisition and resource construction of the bearing section (pipeline section, pole section, direct buried section, wall-mounted section, and lead-in section) is completed with the spatial resources or optical equipment as the starting points of the A end and the Z end.

[0053] The GIS system collects spatial resources (sites, network resource points, business areas), optical equipment (fiber distribution boxes, optical cross-connection boxes), and bearing points (manholes, electric poles, landmarks, and support points). Then, the optical cable segment is constructed through GIS collection. The facilities at the A / Z end of the optical cable segment select the collected spatial resources, and the equipment selects the collected optical equipment. When constructing the optical cable segment, the optical cable core is automatically generated according to the number of optical cable cores. The external structure of the optical cable system is constructed as shown in the attached figure. Figure 2 shown.

[0054] Each resource records unique identification, Chinese name, English name, deletion identification, city, district, county, longitude, latitude, facility, creation date, modification date, life cycle status, etc. In addition, information should be added according to business requirements during the actual implementation process.

[0055] S2. Optical cable system building module design optical equipment panel diagram, including the equipment's ODM module, tray and terminal and panel arrangement;

[0056] By selecting the local optical cable connected to the optical device end and its opposite end device, the fiber core termination, racking or removal of the panel diagram between the two devices can be completed; by selecting the local optical cable connected to the device, the optical cable can be fused or removed.

[0057] like Figure 3 As shown, each ODM module includes several trays, each tray includes multiple terminals, and the specific number of terminals and panel diagram structure are determined by the designer.

[0058] Then select the optical cables one by one and terminate or fuse the optical cable cores. The actual effect is as shown in the attached figure. Figure 4 As shown, the optical cable core is terminated at the equipment on both sides, and several fusion splices are performed in the middle. In addition to the recorded information mentioned in step 1, the optical cable and the core also mainly record the calculated length, service level (such as provincial trunk line, inter-provincial trunk line, access layer optical cable, etc.), the name of the starting / end facility, the type of the starting / end facility (i.e. the type of the connected bearer point or site), the name of the starting / end machine room, the name of the starting / end equipment, the name of the starting / end equipment (i.e. the type of connected equipment), the type of optical cable, whether it is laid, the optical cable system to which it belongs, the life cycle status (engineering, in the network), whether it is qualified (reported by the ministry and the province), error information (updated by the on-site fault monitoring sensor or operation and maintenance personnel), the optical cable system to which it belongs, and the core also includes the optical cable segment to which it belongs, the terminal name of the A / Z end, and the terminal type of the A / Z end (terminal terminal, virtual direct fusion point, OLT terminal, etc.).

Use a recursive method to search for faults in the specified cable segment. The search steps are as follows:

[0061] (1) Obtain the fiber core group owned by the starting optical cable segment;

[0062] (2) The status of each fiber core and the fiber core to which the fiber core belongs is judged (including whether the fiber cable and fiber core are qualified and error information). If the terminal at the A end or Z end of the fiber core is missing or the status is abnormal, the fault information is recorded;

[0063] (3) Query all next-hop unterminated fiber core groups to which the fiber core ends A and Z of the optical cable segment are connected;

[0064] (4) If the number of fiber core groups connected to ends A and Z is inconsistent with the number of unterminated fiber core groups found at the next hop, it indicates that the connection is abnormal and the fault information is recorded;

[0065] (5) The status of the next-hop fiber core at the A and Z ends of the fiber core and the optical cable segment to which the fiber core belongs are judged (including whether the optical cable and fiber core are qualified and error information). If the terminal at the A or Z end of the fiber core is missing or the status is abnormal, the fault information is recorded;

[0066] (6) The fiber core group at the next hop of the fiber core A and Z ends is regarded as the fiber core group of the starting optical cable segment, and steps (1) to (6) are performed to both ends respectively until the number of the fiber core groups at the next hop is 0.
