An optical cable laying method, an optical cable network, an electronic device, and a storage medium

Abstract

The application discloses an optical cable laying method, an optical cable network, an electronic device and a storage medium. The main node of the optical cable network is determined in a power distribution network, and the main optical cable is laid along the power line and the main node from the substation as the starting point. For each power branch line, the first contact point on the main optical cable is taken as the starting point, and the branch optical cable is laid along the power branch line. The target access node on the power branch line is accessed to the branch optical cable. The plurality of branch optical cables belong to a parallel state. On the one hand, when any branch optical cable is in a fault state or needs to access a new device, only the branch optical cable is operated and maintained, and other branch optical cables are not affected, so that the fault influence range is reduced, and the operation and maintenance difficulty of the optical cable network is reduced. On the other hand, the role of the main node is to segment the main optical cable. When the subsequent main optical cable is damaged or fails by external force, the communication transmission function of the previous main optical cable is not affected, and the influence range is reduced.

[0001] This invention relates to the field of optical cable laying technology, and in particular to an optical cable laying method, an optical cable network, electronic equipment, and a storage medium. Background Technology

[0002] Distribution network communication is a crucial foundation for power distribution and utilization services. Various automated devices in the distribution network connect to the main distribution network management station via communication channels, enabling monitoring and remote control of various distribution network data. Distribution network communication methods mainly include public wireless networks, dedicated fiber optic cables, private wireless networks, and grid carrier communication. Among these, fiber optic communication is increasingly being adopted in developed regions due to its advantages such as stable signal and high data transmission capacity, leading to improved fiber optic coverage.

[0003] However, fiber optic communication also has problems such as high maintenance difficulty and susceptibility to external damage that could lead to fiber optic nodes causing mass channel interruptions. Summary of the Invention

[0004] This invention provides a method for laying optical cables to solve the problems of high maintenance difficulty and susceptibility to external damage to optical fiber nodes, which can lead to mass channel interruptions.

[0005] In a first aspect, the present invention provides a method for laying optical cables, comprising:

[0006] A method for laying optical cables based on a power distribution network, wherein the power distribution network includes a substation, power lines, a distribution substation, and an access node, wherein the power lines include a main power line and at least one power branch line, the main power line is led out from the substation, the power branch line is led out from the main power line, and each power branch line is connected to a distribution substation and an access node;

[0007] The optical cable laying method includes:

[0008] Determine the backbone nodes of the optical fiber network in the power distribution network;

[0009] Starting from the substation, the main optical cable is laid along the power line and main nodes;

[0010] For each power branch line, branch optical cables are laid along the power branch line, starting from the first connection point on the main optical cable;

[0011] Connect the target access node on the power branch line to the branch optical cable.

[0012] Secondly, the present invention provides an optical fiber network, which is laid based on the power distribution network. The power distribution network includes substations, power lines, distribution stations, and access nodes. The power lines include a main power line and at least one power branch line. The main power line is led out from the substation, and the power branch line is led out from the main power line. Each power branch line is connected to a distribution station and an access node.

[0013] The optical cable network includes trunk optical cables and branch optical cables, and the optical cable network is laid by the optical cable laying method as described in the first aspect.

[0014] Thirdly, the present invention provides an electronic device, the electronic device comprising:

[0015] At least one processor; and

[0016] A memory communicatively connected to the at least one processor; wherein,

[0017] The memory stores a computer program that can be executed by the at least one processor, the computer program being executed by the at least one processor to enable the at least one processor to perform the optical cable laying method described in the first aspect of the present invention.

[0018] Fourthly, the present invention provides a computer-readable storage medium storing computer instructions that, when executed by a processor, implement the optical cable laying method described in the first aspect of the present invention.

[0019] The optical cable laying method provided in this invention determines the backbone nodes of the optical cable network in the power distribution network. Starting from the substation, the backbone optical cable is laid along the power lines and backbone nodes. For each power branch line, branch optical cables are laid along the power branch line, starting from the first connection point on the backbone optical cable. The target access node on the power branch line is connected to the branch optical cable. By laying the backbone optical cable first and then laying the branch optical cable along the power branch line starting from the first connection point on the backbone optical cable, multiple branch optical cables are in parallel. On the one hand, when any branch optical cable is in a fault state or needs to be connected to new equipment, only that branch optical cable needs to be maintained, and other branch optical cables are not affected, which can reduce the scope of fault impact and reduce the maintenance difficulty of the optical cable network. On the other hand, the role of the backbone node is to segment the backbone optical cable.

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0030] Example 1

[0031] Figure 1 This is a flowchart of an optical cable laying method provided in Embodiment 1 of the present invention. This embodiment is applicable to situations where optical cables are laid based on power distribution networks, such as... Figure 2 As shown, Figure 2 This is a diagram of a power distribution network structure, which includes substation 100 and power lines (…). Figure 2(Not shown in the image) Substation 301 and access node 302, the power line includes a main power line 200 and at least one power branch line 300. The main power line 200 is led out from substation 100 and erected to another substation 100. The power branch line 300 is led out from the main power line 200. Each power branch line 300 is connected to substation 301 and access node 302. Figure 2 This is merely an example and does not impose any restrictions on distribution network structures.

[0032] like Figure 1 As shown, the optical cable laying method includes:

[0033] S101. Determine the backbone nodes of the optical fiber network in the distribution network.

[0034] The backbone node of an optical fiber network, also known as the backbone optical node, refers to the main optical fiber formed by aggregating one or more branch optical cables and connecting them to the relay node. Once the backbone node is determined, it can only connect to the assigned branch optical cables and cannot directly connect to government and enterprise customers, access network nodes, video surveillance, or base station optical cables. When the backbone node uses an optical distribution box or ODF rack, the junction box and ODF rack should be set with partitioned termination positions, including the backbone optical cable termination area from the backbone node to the OLT node, the distribution termination area from the backbone node to the distribution optical node, and the splitter termination area.

[0035] In one alternative embodiment, determining the backbone node of the optical fiber network in the power distribution network includes: for each power branch, determining the backbone node of the optical fiber network from the substations on the power branch.

[0036] In another alternative embodiment, determining the backbone nodes of the optical fiber network in the power distribution network further includes: determining the backbone nodes of the optical fiber network from ring main units, distribution rooms or transformer substations on the main power line.

[0037] The role of the backbone node is to segment the backbone optical cable. When the backbone optical cable behind is damaged by external force (e.g., cut by human intervention) or malfunctions, the communication transmission function of the backbone optical cable in front is not affected, which can reduce the scope of impact.

[0038] It should be noted that the number of first connections on the trunk optical cable is the same as the number of branch optical cables, while the number of trunk nodes is one or more.

[0039] Considering that the main node segments the main optical cable, its main function is to segment different branch optical cables. The main node is located after at least one first connection point so that it can play the role of segmenting branch optical cables.

[0040] S102. Starting from the substation, lay the main optical cable along the power line and main nodes.

[0041] The power line includes the main power line and the branch power line. That is, in this step, the main optical cable can be laid along the main power line and the main node, or it can be laid along the main power line, the branch power line and the main node. This invention does not limit this.

[0042] It should be noted that, as Figure 2 As shown, the main optical cable can be led out from the substation and laid all the way to another substation.

[0043] However, when the trunk optical cable has a tree-like or chain-like structure, the trunk optical cable is led out from the substation, but the other end of the trunk optical cable is the terminal distribution room or transformer area.

[0044] S103. For each power branch line, starting from the first connection point on the main optical cable, lay branch optical cables along the power branch line.

[0045] The first connection point is the point where the branch optical cable connects to the trunk optical cable (T-connection). Therefore, the branch optical cable starts from the first connection point. Since the power branch lines are laid along the access nodes, the branch optical cable can also be laid along the power branch lines, thus facilitating network communication to the access nodes.

[0046] S104. Connect the target access node on the power branch line to the branch optical cable.

[0047] The target access node includes at least one of a substation, a transformer area, and a pole-mounted switch, which means that the optical cable is connected to the target access node.

[0048] Since power branches are connected in parallel and do not affect each other, the branch optical cables built based on these power branches also do not affect each other. When any branch optical cable is in a faulty state or needs to be connected to new equipment, maintenance can be performed only on that branch optical cable, while other branch optical cables are unaffected. This reduces the scope of the fault and lowers the maintenance difficulty of the optical cable network.

[0049] If a new branch optical cable is to be built, a first joint is to be built on the trunk optical cable, and the new branch optical cable is to be fused to the trunk optical cable at the first joint; if the first joint is to be decommissioned, the corresponding branch optical cable can be removed.

[0050] The optical cable laying method provided in this invention determines the backbone nodes of the optical cable network in the power distribution network. Starting from the substation, the backbone optical cable is laid along the power lines and backbone nodes. For each power branch line, branch optical cables are laid along the power branch line, starting from the first connection point on the backbone optical cable. The target access node on the power branch line is connected to the branch optical cable. By laying the backbone optical cable first and then laying the branch optical cable along the power branch line starting from the first connection point on the backbone optical cable, multiple branch optical cables are in parallel. On the one hand, when any branch optical cable is in a fault state or needs to be connected to new equipment, only that branch optical cable needs to be maintained, and other branch optical cables are not affected, which can reduce the scope of fault impact and reduce the maintenance difficulty of the optical cable network. On the other hand, the role of the backbone node is to segment the backbone optical cable. When the backbone optical cable that follows is damaged by external force (e.g., cut by human intervention) or fails, the communication transmission function of the backbone optical cable that precedes it is not affected, which can reduce the scope of impact.

[0051] Example 2

[0052] Figure 3 This is a flowchart of an optical cable laying method provided in Embodiment 2 of the present invention. This embodiment of the present invention is an optimization based on Embodiment 1 described above, such as... Figure 3 As shown, the optical cable laying method includes:

[0053] S301. For each power branch line, determine the backbone node of the optical fiber network from the substations on the power branch line.

[0054] A power distribution station can be a power distribution room or a site with the conditions for equipment installation.

[0055] Generally, the first substation in a power branch line is used as the backbone node of the optical fiber network because the first substation in a power branch line is closest to the main power line, which can reduce the length of the main optical fiber cable and save on the materials used for the main optical fiber cable.

[0056] like Figure 4 As shown, Figure 4 This is a schematic diagram of a fiber optic cable network based on a power distribution network, with the first substation 301 in the power branch line 300 serving as the backbone node of the fiber optic cable network.

[0057] S302. For the first main node, starting from the substation, lay the main optical cable along the power line to the first main node.

[0058] like Figure 4 As shown, the first trunk node is the substation X1 (301). Starting from the substation 100, the trunk optical cable 400 is laid along the power lines (power main line 200 and power branch line 300) to the first trunk node, namely the substation X1 (301).

[0059] S303. For a current backbone node that is not the first backbone node, the backbone optical cable is laid from the previous backbone node along the power line to the current backbone node.

[0060] like Figure 4 As shown, let the current backbone node that is not the first backbone node be the substation Y1 (301). Starting from the substation 100, the backbone optical cable 400 is laid along the power lines (power main line 200, power branch line 300) to the current backbone node, namely the substation Y1 (301).

[0061] S304. For each power branch line, starting from the first connection point on the main optical cable, lay branch optical cables along the power branch line.

[0062] A typical backbone optical cable is a 72-core cable, meaning it contains 72 optical fibers. Each branch cable connects to at least one optical fiber, enabling it to provide network communication services. In one example, each branch cable connects to four optical fibers. Therefore, if one fiber in the backbone cable fails, the network of the corresponding branch cable will not be affected.

[0063] Specifically, the branch optical cable is led out from the trunk optical cable through a T-connection.

[0064] S305. Connect the target access node on the power branch line to the branch optical cable.

[0065] S304-S305 are similar to S103-S104 in Embodiment 1. For details, please refer to S103-S104. They will not be described here.

[0066] In one alternative embodiment, when an old trunk node on a power branch line is decommissioned, a new trunk node is determined from other substations along the power branch line; the junction of the new trunk node and the power branch line is designated as a second junction; and a target branch optical cable is constructed between the first and second junctions. Figure 4 As shown, the connection point between the old backbone node and the power branch is the first connection point A. When the old backbone node substation X1 (301) is decommissioned, a new backbone node, substation X2 (301), is determined from other substations in the power branch. The connection point between substation X2 (301) and the power branch is the second connection point B. At this time, a target branch optical cable is constructed between the first connection point A and the second connection point B. Finally, it is also necessary to terminate the fiber optic cable at substation X2 (301). The jumper fiber coming out of the terminal box is called termination. The purpose of terminating the optical cable directly connected to the switch rack is to facilitate the direct connection of the optical cable to the ODF frame. The optical fiber distribution frame (ODF) is used for the termination and distribution of the central office backbone optical cable in the optical fiber communication system, which can conveniently realize the connection, distribution and scheduling of optical fiber lines.

[0067] The construction requirements for the target branch optical cable are the same as those for the trunk optical cable. In one optional embodiment, if the trunk optical cable has 72 optical cores, then the target branch optical cable should also have 72 optical cores.

[0068] In this embodiment, since the backbone node can ensure that the preceding backbone optical cable and branch optical cable are not affected by the subsequent backbone optical cable, a backbone node is set between any two adjacent branch optical cables, which can implement fine control and minimize the impact of the subsequent backbone optical cable on the preceding backbone optical cable and branch optical cable.

[0069] Example 3

[0070] Figure 5 This is a flowchart of an optical cable laying method provided in Embodiment 3 of the present invention. This embodiment of the present invention is an optimization based on Embodiment 1 described above, such as... Figure 5 As shown, the optical cable laying method includes:

[0071] S501. Determine the main nodes of the optical fiber network from the ring network cabinets on the main power line and from the distribution rooms or transformer substations.

[0072] The function of a backbone node is to segment the backbone optical cable. When a downstream backbone optical cable is damaged by external forces (e.g., cut by human intervention) or experiences a fault, the communication transmission function of the upstream backbone optical cable remains unaffected, thus reducing the impact area. Distribution rooms or transformer substations at the end of the main power line are not considered backbone nodes.

[0073] It should be noted that there must be at least one backbone node. Backbone nodes are primarily ring main units, distribution rooms, or transformer substations. On one hand, not every two adjacent power branches necessarily have a corresponding ring main unit, distribution room, or transformer substation (i.e., a backbone node). On the other hand, even if every two adjacent power branches have a corresponding ring main unit, distribution room, or transformer substation, it is not necessary to designate every single one of these as a backbone node. In summary, a backbone node is not necessarily required between two adjacent power branches.

[0074] S502. Starting from the substation, lay the main optical cable along the power line and main nodes.

[0075] like Figure 6 As shown, Figure 6This is a schematic diagram of a fiber optic network structure based on a power distribution network. The backbone fiber optic cable 400 originates from substation 100 and is laid along the main power line 200 to another substation 100. Of course, the end of the backbone fiber optic cable 400 can also be a distribution room or a transformer substation; there are no restrictions on this. Furthermore, backbone node C is located on the main power line 200 and also on the backbone fiber optic cable 400.

[0076] S503. For each power branch line, starting from the first connection point on the main optical cable, lay branch optical cables along the power branch line.

[0077] S504. Connect the target access node on the power branch line to the branch optical cable.

[0078] like Figure 6 As shown, branch optical cables 500 are laid along power branch lines 300, starting from the first connection point A on the main optical cable 400. At this time, the substation 301 and the access node 302 are both connected to the branch optical cable.

[0079] In an alternative embodiment, if a backbone node is decommissioned, the backbone node can be changed, or the optical fibers of the backbone cable can be directly spliced, i.e., the backbone node can be abandoned.

[0080] Compared to Example 2, which involves laying the trunk optical cable along the main power line, branch power lines, and substations, this example lays the trunk optical cable along the main power line, significantly shortening the trunk cable length and reducing material consumption. Furthermore, the structure of the trunk optical cable is greatly simplified, thus reducing maintenance difficulty in the event of a trunk cable failure. Similarly, by setting trunk nodes, damage or failure of subsequent trunk optical cables can prevent impact on earlier trunk optical cables, minimizing the scope of the impact.

[0081] It should be noted that, in principle, distribution network optical cables should be laid along the 10kV cable route in ducts, but depending on the actual situation, they can also be partially laid along power cable trenches.

[0082] To clearly compare the two optical cable laying methods in Embodiment 2 and Embodiment 3, the following table is used for illustrative purposes.

[0083]

[0084]

[0085] The optical cable laying methods in Examples 2 and 3 are different. Specifically, different optical cable laying methods can be selected according to the local conditions of the area where the cable needs to be laid, the number of termination or T-junction points, and the layout of the power distribution room and access node. For example, when it is required that there is a trunk node between every two adjacent branch optical cables for optical cable segment protection, the optical cable laying method of Example 2 can be used. When the power distribution room is far away from the main power line or power branch line, the optical cable laying method of Example 3 can be used to reduce the laying length of the trunk optical cable.

[0086] Example 4

[0087] The present invention provides an optical fiber network based on a power distribution network. The power distribution network includes a substation, power lines, a distribution station, and access nodes. The power lines include a main power line and at least one power branch line. The main power line is led out from the substation, and the power branch line is led out from the main power line. Each power branch line is connected to a distribution station and an access node.

[0088] The optical fiber network includes trunk optical cables and branch optical cables. The optical fiber network is laid by the optical fiber laying method as described in any embodiment of the present invention, and has the corresponding beneficial effects.
