In addition, "and or or" in the specification and claims represents at least one of the connected objects, and the character "or" generally indicates that the objects associated before and after are in an "or" relationship.

[0041] The cable laying path determination method based on three-dimensional space information provided in the embodiment of the present application can be applied to the cable laying path generation scenario. The cable laying path determination method based on three-dimensional space information provided in the embodiment of the present application, the execution subject of each step can be a computer device, which refers to any electronic device with data calculation, processing and storage capabilities, such as mobile phones, PCs (Personal Computers), tablet computers and other terminal devices, and can also be servers and other devices, which are not limited in the embodiment of the present application.

[0042] Figure 1 A flowchart of a method for determining a cable laying path based on three-dimensional space information provided by an embodiment of the present invention is shown in FIG. Figure 1 As shown, specifically including:

[0043] Step S101, obtaining laying area information and cable characteristic information of the cable to be laid, wherein the laying area information includes a laying starting point, a laying end point and sub-area storage information of multiple laying sub-areas, and the sub-area storage information includes sub-area environmental data and sub-area three-dimensional space information.

[0044] Among them, the cable to be laid is used to represent the cable waiting to be laid, the laying area information is used to represent the various relevant data information of the geographical area where the cable is laid, the laying starting point is used to represent the starting position point of the cable laying, the laying end point is used to represent the ending position point of the cable laying, the laying sub-area can be a plurality of sub-areas pre-divided in the laying area of ​​the cable to be laid, the sub-area storage information is used to represent the relevant data information of each pre-stored laying sub-area, the sub-area environmental data is used to represent the environmental data related to the laying sub-area, which can be environmental data such as temperature data and humidity data, the sub-area three-dimensional space information is used to represent the data information related to the cable laying path planning in the three-dimensional space of the laying sub-area, and the cable characteristic information is used to represent the relevant data information of the various performances of the cable. Obtaining the laying area information and cable characteristic information of the cable to be laid can improve the dimension of the reference factor to ensure the rationality of the cable laying path.

[0045] Step S102: Generate multiple candidate paths for the cable to be laid according to the laying starting point and the laying end point, and determine multiple sub-paths of the candidate paths and corresponding sub-path environmental data according to the laying sub-area and the sub-area environmental data.

[0046] Among them, the path to be selected is used to characterize the path to be screened as an available laying path, the sub-path is used to characterize each path segment in the path to be selected, and the sub-path environmental data is used to characterize the environment-related data on the sub-path. In one embodiment, a path connecting the laying starting point to the laying end point is generated in the laying area of ​​the cable to be laid and determined as the path to be selected, and multiple sub-paths and corresponding sub-path environmental data of the path to be selected are determined according to the laying sub-area and the sub-area environmental data. Optionally, each passing sub-area of ​​the path to be selected in the laying sub-area is determined, and the path part in the path to be selected that is in the same passing sub-area is determined as a sub-path, and the sub-area environmental data of the passing sub-area corresponding to the sub-path is determined as the sub-path environmental data of the sub-path, and the passing sub-area is used to characterize the laying sub-area passed by the path to be selected. Dividing the path to be selected into multiple sub-paths can facilitate a more in-depth analysis of the availability of the path to be selected and improve the rationality of the available laying paths. An exemplary example may be that there are 16 laying sub-areas in total, and the number of laying sub-areas, i.e., passing sub-areas, passed by the path to be selected a in the laying sub-area is 7, such as Figure 2 As shown, Figure 2A schematic diagram of a path to be selected passing through a laying sub-area provided in an embodiment of the present invention, wherein a large square represents a laying area of ​​a cable to be laid, and each small square divided by a dotted line represents a laying sub-area, 01 is a laying starting point, 02 is a laying end point, and the connection line from 01 to 02 is a path to be selected a, and the small squares indicated by 03, 04, 05, 06, 07, 08, and 09 are passing sub-areas of the path to be selected a, and the path segments passing through the sub-areas are sub-paths of the path to be selected a. In another embodiment, laying sub-areas with the same and adjacent sub-area environmental data are determined as a combined sub-area, and each passing sub-area of ​​the path to be selected in the combined sub-area and other laying sub-areas is determined, and the path portion in the path to be selected that is in the same passing sub-area is determined as a sub-path, and the corresponding sub-path environmental data is determined as the sub-path environmental data.

[0047] Step S103: determining a plurality of available laying paths in the candidate paths based on the sub-path environment data of each sub-path and the cable characteristic information.

[0048] Among them, the available laying path is used to characterize the path that can be used to lay cables. In one embodiment, the sub-path environmental data of each sub-path of the selected path and the cable characteristic information of the cable to be laid are input into the trained judgment model. If the output result of the judgment model is available, the selected path is determined as an available laying path. Optionally, the sub-path environmental data of each sub-path is matched with the cable characteristic information of the cable to be laid respectively. When the matching results corresponding to each sub-path of the selected path are all successful, the selected path is determined as an available laying path. Through the matching process of the sub-path environmental data and the cable characteristics, it is possible to determine whether the surrounding environment of the selected path will affect the cable characteristics, thereby ensuring the rationality of the available laying path.

[0049] Step S104: Calculate the path weight values ​​of the available laying paths based on the three-dimensional spatial information of the sub-area, and prioritize the available laying paths according to the path weight values ​​to obtain an optimal laying path.

[0050] Among them, the path weight value is used to characterize the suitability of the available laying path for cable laying. In one embodiment, the laying path is comprehensively evaluated according to the three-dimensional spatial information of the sub-area to obtain a comprehensive evaluation value, and the path weight value of the available laying path is obtained by querying the corresponding path weight mapping table based on the comprehensive evaluation value, and the available laying paths are prioritized according to the path weight value to obtain the optimal laying path. An exemplary example may be that there are five available laying paths, namely path 1, path 2, path 3, path 4, and path 5, and the corresponding path weight values ​​are determined to be 0.3, 0.5, 0.8, 0.6, and 0.9, respectively, and are ranked from high to low in priority as path 5, path 3, path 4, path 2, and path 1, then path 5 ranked first is determined as the optimal laying path. Optionally, a path weight value calculation method may be: calculate the sub-path weight value corresponding to each sub-path in the available laying path according to the three-dimensional spatial information of the sub-area, and determine the path weight value of each available laying path based on the sub-path weight value. The weight value of the sub-path is calculated through the three-dimensional spatial information of the sub-region, and then the weight value of the available laying path is determined, which can improve the rationality and accuracy of the path weight value.

[0051] From the above, it can be seen that the laying area information and cable characteristic information of the cable to be laid are obtained, the laying area information includes the laying starting point, the laying end point and the sub-area storage information of multiple laying sub-areas, the sub-area storage information includes the sub-area environmental data and the sub-area three-dimensional space information, and multiple candidate paths for the cable to be laid are generated according to the laying starting point and the laying end point. According to the laying sub-area and the sub-area environmental data, multiple sub-paths of the candidate paths and the corresponding sub-path environmental data are determined, and based on the sub-path environmental data of each sub-path and the cable characteristic information, multiple available laying paths are determined in the candidate paths, and the path weight values ​​of the available laying paths are calculated based on the sub-area three-dimensional space information. According to the path weight values, the available laying paths are prioritized to obtain the optimal laying path. This solution determines the cable laying path by referring to three-dimensional spatial information, which solves the problem that the reference factors for selecting the laying path in the existing cable laying technology are limited to the two-dimensional plane and lack of consideration of three-dimensional spatial factors, resulting in low rationality of the cable laying path and affecting the safe operation of the cable. By referring to the three-dimensional spatial information, the final laying path can be made more reasonable, which is convenient for later maintenance and inspection and reduces the cable failure rate.

[0052] Figure 3 A flowchart of another method for determining a cable laying path based on three-dimensional space information provided by an embodiment of the present invention provides an optional specific process for determining an available laying path, such as Figure 3 As shown, specifically including:

[0053] Step S201, obtaining laying area information and cable characteristic information of the cable to be laid, wherein the laying area information includes a laying starting point, a laying end point, and sub-area storage information of multiple laying sub-areas, wherein the sub-area storage information includes sub-area environmental data and sub-area three-dimensional space information.

[0054] Step S202: Generate multiple candidate paths for the cable to be laid according to the laying starting point and the laying end point, and determine multiple sub-paths of the candidate paths and corresponding sub-path environmental data according to the laying sub-area and the sub-area environmental data.

[0055] Step S203: Match the sub-path environment data of each sub-path with the cable characteristic information respectively. If the matching results corresponding to each sub-path of the candidate path are all successful, the candidate path is determined as an available laying path.

[0056] Among them, the sub-path environmental data of each sub-path is matched with the cable characteristic information respectively, and when the matching results corresponding to each sub-path of the selected path are all matched successfully, the selected path is determined as an available laying path. Optionally, the sub-path environmental data includes multiple environmental attributes and corresponding environmental attribute values, and the environmental attributes can be environmental attributes such as temperature and humidity. The cable characteristic information includes multiple cable characteristics and corresponding standard tolerance ranges. The cable characteristics can be characteristics such as heat resistance and moisture resistance. The standard tolerance range is used to characterize the range of corresponding influencing factor values ​​that the cable characteristics can withstand. A matching processing method can be: determining the associated cable characteristics that have an associated relationship with the environmental attributes in the cable characteristics, and determining whether the environmental attribute values ​​of the environmental attributes are within the standard tolerance range of the corresponding associated cable characteristics. If they are within the standard tolerance range of the corresponding associated cable characteristics, then the match is determined to be successful, otherwise, the match is determined to fail. An exemplary example may be that the environmental characteristics include temperature and humidity, the cable characteristics include heat resistance and moisture resistance, the heat resistance is correlated with the temperature, and the corresponding standard tolerance range is (-10°C, 45°C], the moisture resistance is correlated with the humidity, and the corresponding standard tolerance range is (0, 70%], the selected path a includes three sub-paths, namely sub-path 1, sub-path 2 and sub-path 3, the temperature value of sub-path 1 is 30°C, the humidity value is 90%, the temperature value of sub-path 2 is 28°C, the humidity value is 40%, the temperature value of sub-path 3 is 26°C, the humidity value is 30%, and the humidity value corresponding to sub-path 1 is not within the corresponding standard tolerance range, that is, sub-path 1 fails to match. Failed, sub-path 2 and sub-path 3 matched successfully, and there is a sub-path that failed to match in the candidate path a, then the candidate path a is not an available laying path. In another embodiment, the sub-path environment data includes multiple environmental attributes and corresponding environmental attribute values, and the cable characteristic information includes multiple cable characteristics and corresponding characteristic values. A matching processing method can be: one-to-one correspondence between environmental attributes and cable characteristics according to a preset association relationship, querying a conversion performance value comparison table according to the environmental attribute value to obtain a conversion performance value corresponding to the environmental attribute, matching the conversion performance value with the corresponding characteristic value, and determining that the match is successful when the conversion performance value is less than the corresponding characteristic value, otherwise, determining that the match fails.

[0057] Step S204: Calculate the path weight values ​​of the available laying paths based on the three-dimensional spatial information of the sub-area, and prioritize the available laying paths according to the path weight values ​​to obtain an optimal laying path.

[0058] As can be seen from the above, the sub-path environmental data of each sub-path is matched with the cable characteristic information respectively, and when the matching results corresponding to each sub-path of the candidate path are all matched successfully, the candidate path is determined as an available laying path. This solution can determine whether the surrounding environment of the candidate path will affect the cable characteristics through the matching processing of the sub-path environmental data and the cable characteristics, thereby ensuring the rationality of the available laying path.

[0059] Figure 4 A flowchart of another method for determining a cable laying path based on three-dimensional space information provided by an embodiment of the present invention provides an optional specific process for determining a path weight value, such as Figure 4 As shown, specifically including:

[0060] Step S301, obtaining laying area information and cable characteristic information of the cable to be laid, wherein the laying area information includes a laying starting point, a laying end point, and sub-area storage information of multiple laying sub-areas, wherein the sub-area storage information includes sub-area environmental data and sub-area three-dimensional space information.

[0061] Step S302: Generate multiple candidate paths for the cable to be laid according to the laying starting point and the laying end point, and determine multiple sub-paths of the candidate paths and corresponding sub-path environmental data according to the laying sub-area and the sub-area environmental data.

[0062] Step S303: determining a plurality of available laying paths in the candidate paths based on the sub-path environment data of each sub-path and the cable characteristic information.

[0063] Step S304: calculate the subpath weight value corresponding to each subpath in the available laying path according to the three-dimensional spatial information of the sub-area, determine the path weight value of each available laying path based on the subpath weight value, and prioritize the available laying paths according to the path weight value to obtain the optimal laying path.

[0064] Among them, the subpath weight value corresponding to each subpath in the available laying path is calculated according to the three-dimensional spatial information of the subregion, and the path weight value of each available laying path is determined based on the subpath weight value. Optionally, the three-dimensional spatial information of the subregion includes crowd information, weather information and building information, and a method for determining the subpath weight value may be: determining the information weight values ​​corresponding to the crowd information, weather information and building information in the three-dimensional spatial information of the subregion, multiplying each information weight value with the corresponding preset weight and superimposing them to obtain the subpath weight value of the corresponding subpath. Optionally, a method for determining the path weight value may be: determining the number of subpath weight values ​​in the available laying path that are less than the preset comparison weight, and calculating the average weight value of each subpath weight value in the available laying path, determining the adjustment value corresponding to the average weight value according to the number of subpath weight values ​​in the available laying path that are less than the preset comparison weight, and adjusting the average weight value according to the adjustment value to obtain the path weight value of the available laying path. An exemplary example may be that the preset weights corresponding to the crowd information, weather information and building information are 0.2, 0.3 and 0.5 respectively, and the available laying path a includes 6 sub-paths, namely sub-path 1, sub-path 2, sub-path 3, sub-path 4, sub-path 5 and sub-path 6. The crowd information corresponding to sub-path 1 is 300 people / h, the weather information is that the probability of bad weather is 30%, and the building information is that the building occupies 50% of the area. According to the crowd information, weather information and building information of sub-path 1, the corresponding information weight values ​​are 0.3, 0.6 and 0.2 respectively, and each information weight value is multiplied by the corresponding preset weight and superimposed to obtain the sub-path 1. The path weight value is 0.34 (0.3*0.2+0.6*0.3+0.2*0.5). In the same way, the sub-path weight values ​​corresponding to sub-paths 2, 3, 4, 5, and 6 are determined to be 0.2, 0.1, 0.8, 0.9, and 0.6, respectively. The average weight value of the weight values ​​of each sub-path in the available laying path is 0.49. The preset comparison weight is 0.3. The number of sub-path weight values ​​less than 0.3 in the available laying path a is 2. The corresponding adjustment value is -0.1 obtained by querying the comparison table of the preset number and the adjustment value. The average weight value is adjusted according to the adjustment value to obtain the path weight value of the available laying path a as 0.39 (0.49-0.1). In another embodiment, the flow of people information, weather information, and building information in the three-dimensional space information of the sub-region are input into the trained sub-path weight evaluation model to obtain the sub-path weight value of the corresponding sub-path, and the average weight value of the weight values ​​of each sub-path in the available laying path is calculated, and the average weight value is determined as the path weight value of the available laying path.

[0065] From the above, it can be seen that the subpath weight value corresponding to each subpath in the available laying path is calculated according to the sub-region three-dimensional spatial information, the path weight value of each available laying path is determined based on the subpath weight value, and the available laying paths are prioritized according to the path weight value to obtain the optimal laying path. This solution calculates the weight value of the subpath through the sub-region three-dimensional spatial information, and then determines the weight value of the available laying path, which can improve the rationality and accuracy of the path weight value.

[0066] Figure 5 This is a module structure diagram of a cable laying path determination system based on three-dimensional space information provided by an embodiment of the present invention. The system is used to execute the cable laying path determination method based on three-dimensional space information provided by the above embodiment, and has the corresponding functional modules and beneficial effects of the execution method. Figure 5 As shown, the system specifically includes:

[0067] An acquisition module 101 is used to acquire laying area information and cable characteristic information of the cable to be laid, wherein the laying area information includes a laying starting point, a laying end point, and sub-area storage information of multiple laying sub-areas, wherein the sub-area storage information includes sub-area environmental data and sub-area three-dimensional space information;

According to the laying sub-area and the sub-area environmental data, multiple sub-paths of the candidate paths and the corresponding sub-path environmental data are determined, and based on the sub-path environmental data of each sub-path and the cable characteristic information, multiple available laying paths are determined in the candidate paths, and the path weight values ​​of the available laying paths are calculated based on the sub-area three-dimensional space information. According to the path weight values, the available laying paths are prioritized to obtain the optimal laying path. This solution determines the cable laying path by referring to three-dimensional spatial information, which solves the problem that the reference factors for selecting the laying path in the existing cable laying technology are limited to the two-dimensional plane and lack of consideration of three-dimensional spatial factors, resulting in low rationality of the cable laying path and affecting the safe operation of the cable. By referring to the three-dimensional spatial information, the final laying path can be made more reasonable, which is convenient for later maintenance and inspection and reduces the cable failure rate.
