[0038] S110. Number the nodes of the cable channel to form node numbers, and determine the connection relationship of each node number; wherein the cable channel includes a cable trench, a cable bridge and a cable shaft, and the nodes of the cable channel include a turning point, a three-way point, a four-way point, a starting point and an end point of the cable channel.

[0039] Specifically, the reference point in the cable channel design diagram can be used as the origin, and each node can be numbered according to the distance from the origin to form a node number, and the connection relationship of each node number can be determined. Exemplarily, each node can be numbered from small to large according to the distance from the origin, and the node number can start from 1 and increase sequentially.

[0040] S120: Determine the number of channel layers of each cable channel, and number each channel layer to form a layer number.

[0041] Specifically, according to the specification model of each cable channel, the channel data of each specification of the cable channel can be confirmed in the cable channel database, including the number of channel layers of each cable channel, and each layer of the channel layer can be numbered to form a layer number. Exemplarily, if the channel layer of the cable channel includes a left channel layer and a right channel layer, each layer of the left channel layer is numbered to form a left channel layer number, and each layer of the right channel layer is numbered to form a right channel layer number, and a layer number is formed according to the left channel layer number and the right channel layer number; if the channel layer of the cable channel is not layered on both sides, each layer of the channel layer can be numbered according to the number of channel layers of each cable channel to form a layer number.

[0043] Specifically, the starting point coordinate data and the terminal point coordinate data of each cable can be determined according to the connection information of each cable, and the routing path of each cable in the cable channel can be determined by the shortest path method according to the starting point coordinate data and the terminal point coordinate data of each cable. The connection information of the cable is the location information of the cable starting point connection device and the location information of the cable terminal connection device.

[0044] S140. Rank the cables in each cable channel section in the channel layer where the cable channel section is located according to the cable type and routing path of each cable; wherein the cable channel section is the cable channel between adjacent node numbers.

Among them, the cable types include high-voltage cables, low-voltage power cables and control cables.

[0046] S150. In each cable channel section, the cables on the same channel layer are ranked according to the head end coordinate data and the end end coordinate data of the cables on the same layer in the cable channel section, and the cable number of each cable is determined; wherein the cable number is determined according to the node number and the layer number of the cable channel section and the ranking of the cables on the same layer in the cable channel.

[0047] Specifically, in each cable channel interval, it is determined whether the head end coordinate data and the terminal end coordinate data of the cables on the same layer in the cable channel interval are within the cable channel interval, and the cables on the same channel layer are ranked according to the judgment result and the length of each cable on the same layer in the cable channel interval, and the cable number of each cable is determined. Exemplarily, if the head end coordinate data or the terminal end coordinate data of multiple cables on the same layer in the cable channel interval are within the cable channel interval, the cables with each head end coordinate data or the terminal end coordinate data in the cable channel interval are centrally arranged, and the lengths of each cable centrally arranged in the cable channel interval are compared, and the cables are ranked in order from small to large, and numbered, and then the cable number of each cable can be determined according to the node number of the cable channel interval, the layer number and the ranking of the cables on the same layer in the cable channel. Exemplarily, the cable number is 1-2-L1-8, where 1-2 represents the node number of the cable channel interval, i.e., the cable channel interval between the first node and the second node; L1 represents the first layer of the channel layer of the cable channel; and 8 represents the eighth cable on the same layer in the cable channel.

[0048] A cable laying method provided by an embodiment of the present invention forms a node number by numbering the nodes of the cable channel, and determines the connection relationship of each node number, determines the number of layers of the channel layer of each cable channel, and numbers each layer of the channel layer to form a layer number, determines the routing path of each cable according to the head end coordinate data and the terminal coordinate data of each cable, ranks the cables in each cable channel interval in the channel layer where the cable channel interval is located according to the cable type and routing path of each cable, and in each cable channel interval, ranks the cables in the same channel layer according to the head end coordinate data and the terminal coordinate data of the cables on the same layer in the cable channel interval, and determines the cable number of each cable. During the cable maintenance and inspection process, the cable laying method provided by the embodiment of the present invention can accurately locate the position of each cable in the cable channel, reduce the cable maintenance time, improve the cable maintenance efficiency, and avoid accidents or electric shock risks caused by unclear cable positions, thereby improving the safety of maintenance personnel's operations.

[0049] Furthermore, in each cable channel section, the cables on the same channel layer are ranked according to the head end coordinate data and the end end coordinate data of the cables on the same layer in the cable channel section, and the cable number of each cable is determined, including:

[0050] In each cable channel interval, determine whether the starting and ending coordinate data of the cables on the same layer in the cable channel interval are within the cable channel interval, and rank the cables on the same channel layer based on the determination result and the length of each cable on the same layer in the cable channel interval, and determine the cable number of each cable.

[0051] Specifically, if the same layer in the cable channel section includes double-ended connection cables, each double-ended connection cable is first ranked according to its length in the cable channel section, and the cable number of each double-ended connection cable is determined from large to small according to the ranking result; wherein the double-ended connection cable is a cable whose head end coordinate data and terminal end coordinate data are both within the cable channel section;

[0052] If the same layer in the cable channel section includes single-ended connection cables, the cables are ranked according to the length of each single-ended connection cable in the cable channel section, and the cable numbers of each single-ended connection cable are determined from large to small based on the ranking result; wherein the single-ended connection cable is a cable whose head end coordinate data or terminal end coordinate data is within the cable channel section;

[0053] If the same layer in the cable channel interval includes straight-through interval cables, each straight-through interval cable is ranked arbitrarily, and the cable number of each straight-through interval cable is determined according to the ranking order of the straight-through interval cables; among which, the straight-through interval cable is a cable whose head end coordinate data and end end coordinate data are not within the cable channel interval.

[0054] Further, in each cable channel section, it is determined whether the head end coordinate data and the end end coordinate data of the cables on the same layer in the cable channel section are within the cable channel section, and according to the determination result and the length of each cable on the same layer in the cable channel section, the cables on the same channel layer are ranked, and the cable number of each cable is determined, including:

[0055] If the same layer in the cable channel section includes double-ended connection cables, the double-ended connection cables are first ranked according to their lengths in the cable channel section, and the cable numbers of the double-ended connection cables are determined from large to small according to the ranking results; wherein the double-ended connection cables are cables whose head end coordinate data and terminal end coordinate data are both within the cable channel section;

[0056] If the same layer in the cable channel section includes single-ended connection cables, the cables are ranked according to the length of each single-ended connection cable in the cable channel section, and the cable numbers of each single-ended connection cable are determined from large to small based on the ranking result; wherein the single-ended connection cable is a cable whose head end coordinate data or terminal end coordinate data is within the cable channel section;

[0057] If the same layer in the cable channel interval includes straight-through interval cables, each straight-through interval cable is ranked arbitrarily, and the cable number of each straight-through interval cable is determined according to the ranking order of the straight-through interval cables; among which, the straight-through interval cable is a cable whose head end coordinate data and end end coordinate data are not within the cable channel interval.

[0058] Specifically, first determine whether the same layer in the cable channel interval includes a double-ended connection cable. If the same layer in the cable channel interval includes a double-ended connection cable, rank the cables according to the number of the double-ended connection cables and the length of the double-ended connection cables in the cable channel interval. For example, if the same layer in the cable channel interval includes only one double-ended connection cable, the double-ended connection cable is set at the end of the layer; if the same layer in the cable channel interval includes multiple double-ended connection cables, the multiple double-ended connection cables are concentrated at the end of the layer, and are ranked from small to large according to the length of each double-ended connection cable in the cable channel interval, and the cable number of each double-ended connection cable is determined from large to small according to the ranking result.

[0059] Then, determine whether the same layer in the cable channel interval includes a single-ended connection cable. If the same layer in the cable channel interval includes a single-ended connection cable, rank the cables according to the number of double-ended connection cables and the length of the double-ended connection cables in the cable channel interval. For example, when the same layer in the cable channel interval does not include a double-ended connection cable, if the same layer in the cable channel interval includes only one single-ended connection cable, the single-ended connection cable is arranged at the end of the layer. If the same layer in the cable channel interval includes multiple single-ended connection cables, the multiple single-ended connection cables are concentrated at the end of the layer, and are ranked from small to large according to the length of each single-ended connection cable in the cable channel interval. Ranking, setting and determining the cable number of each single-ended connection cable from large to small according to the ranking result; when the same layer in the cable channel section contains double-ended connection cables, if the same layer in the cable channel section includes only one single-ended connection cable, the single-ended connection cable and the double-ended connection cable are set adjacent to each other; if the same layer in the cable channel section includes multiple single-ended connection cables, the single-ended connection cable with the shortest length is set adjacent to the outermost double-ended connection cable according to the length of each single-ended connection cable in the cable channel section, and the remaining single-ended connection cables are ranked from small to large, and the cable number of each double-ended connection cable is determined from large to small according to the ranking result.

[0060] Finally, determine whether the same layer in the cable channel interval includes a straight-through interval cable. If the same layer in the cable channel interval includes a straight-through interval cable, the straight-through interval cable is set on a side away from the single-ended connection cable and the double-ended connection cable. For example, if the same layer in the cable channel interval includes only one straight-through interval cable, the straight-through interval cable is directly set on a side away from the single-ended connection cable and the double-ended connection cable. If the same layer in the cable channel interval includes only multiple straight-through interval cables, each straight-through interval cable can be ranked arbitrarily, and the cable number of each straight-through interval cable is determined. For example, if the same layer in the cable channel interval includes straight-through interval cables, single-ended connection cables and double-ended connection cables at the same time, the cable number of each straight-through interval cable is determined on the basis of determining the cable number of the single-ended connection cable and the cable number of the single-ended connection cable.

[0061] For example, Figure 2 is a schematic diagram of partial cable laying provided according to an embodiment of the present invention, such as Figure 2 As shown in the figure, in the cable channel section between the first node and the second node, if a certain layer is provided with 8 cables, and it is determined that there are two double-ended connection cables, i.e., green double-ended connection cables, in the layer, the cables are ranked from small to large according to the length of each double-ended connection cable in the cable channel section, and the double-ended connection cable with the smallest length is arranged at the end of the layer, and the cable number of each double-ended connection cable is determined from large to small according to the ranking result, i.e., the cable number of the double-ended connection cable with the smaller length is set to No. 8, and the cable number of the double-ended connection cable with the larger length is set to No. 7; then it is determined that there are two single-ended connection cables, i.e., red single-ended connection cables, in the layer, and the cable number of each single-ended connection cable is determined according to the length of each single-ended connection cable in the cable channel section. The length of the interval is ranked from small to large, and the single-ended connecting cable with the smallest length is set close to the No. 7 double-ended connecting cable, and the cable number of each single-ended connecting cable is determined from large to small according to the ranking result, that is, the cable number of the single-ended connecting cable with a smaller length is set to No. 6, and the cable number of the single-ended connecting cable with a larger length is set to No. 5; finally, it is determined that there are four single-ended connecting cables on this layer, that is, the blue straight-through interval cables, and the four single-ended connecting cables can be ranked arbitrarily according to the actual situation, and the cable number of each straight-through interval cable is determined according to the ranking position, that is, the cable number close to the No. 5 single-ended connecting cable can be set to No. 4, and the cable numbers of the remaining straight-through interval cables are No. 3, No. 2 and No. 1 respectively.

[0062] Furthermore, Figure 3 is another partial cable laying schematic diagram provided according to an embodiment of the present invention, with reference to Figure 3 If at least two double-ended connection cables have equal lengths in the cable channel section, they can be ranked first according to the length of one of the double-ended connection cables in the cable channel section, and then the remaining double-ended connection cables with equal lengths in the cable channel section can be ranked according to the positions of the current double-ended connection cables.

[0063] Here, at least two can be understood as two or more than two.

[0064] Specifically, Figure 3As shown, if the same layer in the cable channel section includes three green double-ended connection cables, wherein two double-ended connection cables have equal lengths in the cable channel section, one double-ended connection cable with a different length from the other double-ended connection cable can be selected for comparison, and the cables are ranked from small to large according to the length of each double-ended connection cable in the cable channel section, and the two double-ended connection cables with the shortest lengths are set at the ends of the layer, wherein the positions of the two double-ended connection cables with equal lengths in the cable channel section can be arbitrarily set according to actual conditions, and the cable number of each double-ended connection cable is determined from large to small according to the ranking results, that is, the cable numbers of the two double-ended connection cables with the shortest lengths are set to 9 and 8, and the cable number of the double-ended connection cable with the longer length is set to 7.

[0065] Furthermore, according to the cable type and routing path of each cable, the cables in each cable channel section are ranked in the channel layer where the cable channel section is located, including:

[0066] Determine the cable type of each cable according to the component arrangement information of each cable;

[0067] According to the cable type and routing path of each cable, the cables in each cable channel section are ranked in the channel layer where the cable channel section is located.

[0068] Specifically, the cables passing through each cable channel section may be determined according to the routing path of each cable; and the cables in each cable channel section may be ranked in the channel layer where the cable channel section is located according to the cable type of the cables in each cable channel section.

[0069] Furthermore, cable types include high voltage cables, low voltage power cables and control cables.

[0070] Furthermore, according to the cable type and routing path of each cable, the cables in each cable channel section are ranked in the channel layer where the cable channel section is located, including:

[0071] According to the cable type and routing path of each cable, high-voltage cables, low-voltage power cables and control cables are arranged in sequence from top to bottom in the channel layer where each cable channel section is located.

[0072] Specifically, after determining the cables passing through each cable channel section according to the routing path of each cable, the high-voltage cables in each cable channel section are prioritized to be arranged in the top layer of the channel layer of the cable channel, and the high-voltage cables are arranged in order from top to bottom until all the high-voltage cables are arranged. For example, if the channel layer of the cable channel is layered on both sides, the top layer on each side must be filled before the next layer is arranged; if the channel layer of the cable channel is not layered on both sides, it only contains one side of the channel layer, and the high-voltage cables are arranged in order from top to bottom. The layer where the high-voltage cables are arranged is taken as the starting layer, and the low-voltage power cables are continued to be laid according to the above method until all the low-voltage power cables are arranged. The layer next to the layer where the low-voltage power cables are arranged is taken as the starting layer, and the control cables are continued to be laid according to the above method until all the control cables are arranged.

[0073] Further, according to the head end coordinate data and the end end coordinate data of each cable, the routing path of each cable is determined, including:

[0074] According to the coordinate data of the beginning and the end of each cable, the routing path of each cable is determined by the shortest path method.

[0075] Specifically, based on the starting end coordinate data and the ending end coordinate data of each cable, the shortest path method is used to determine the routing path of each cable. At the same time, the cable channel through which the routing path of each cable passes, as well as the cable channel interval at the starting end of each cable and the cable channel interval at the ending end of each cable can be determined.

[0076] Further, the number of channel layers of each cable channel is determined, and each channel layer is numbered to form a layer number, including:

[0077] If the channel layer of the cable channel includes a left channel layer and a right channel layer, each layer of the left channel layer is numbered to form a left channel layer number, and each layer of the right channel layer is numbered to form a right channel layer number, and a layer number is formed according to the left channel layer number and the right channel layer number.

[0078] Specifically, if the cable channel is a cable trench with a width greater than or equal to 800 mm, the channel layer of the cable channel includes a left channel layer and a right channel layer. In this case, the left channel layer and the right channel layer can be numbered separately. For example, the layer numbers of the left channel layer are L1, L2, L3..., and the right channel layer are R1, R2, R3... If the cable channel is a cable tray or a cable trench with a width less than 800 mm, it is only necessary to number each layer of the channel layer. For example, the layer numbers are L1, L2, L3...

[0079] The embodiment of the present invention provides a cable laying device, which lays all cables in a cable channel according to the cable laying method described in any of the above embodiments. During the cable maintenance and inspection process, the position of each cable in the cable channel can be accurately located, which reduces the cable maintenance time and improves the cable maintenance efficiency. At the same time, it can avoid accidents or electric shock risks caused by unclear cable positions, and improve the safety of maintenance personnel's operations.

[0080] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps described in the present invention can be executed in parallel, sequentially or in different orders, as long as the desired results of the technical solution of the present invention can be achieved, and this document does not limit this.

[0081] The above specific implementations do not constitute a limitation on the protection scope of the present invention. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
