Description

Technical Field

[0001] The present invention relates to the technical field of data analysis, and in particular to a communication cable laying route analysis system and method based on digital modeling. Background Art

[0002] With the advancement and development of network technology and the construction of 5G mobile networks, people in society are working and studying more and more closely with the network. Therefore, it is extremely important to lay cables reasonably. Cable laying refers to the way of routing cables from the distribution box to the power-consuming equipment or to another device. When laying cables, special attention should be paid to the layout of cable laying and its combination with the actual situation. However, in the actual environment, the surrounding environment can affect the layout of cable laying. Therefore, when laying cables, special attention should be paid to the accuracy of positioning so as not to affect the actual laying process of cables.

[0003] Due to the development of 5G networks, the actual length of cables is now more and more stringent, so it is necessary to improve the accuracy of cable laying. Although the cable laying path can be solved by many methods at present, the cable length will have errors in actual laying, so it is necessary to solve and improve the problems that arise. Summary of the invention

[0025] The collision factor analysis unit is used to analyze whether the collision angle between the randomly generated laying path and the contour curve in the two-dimensional model is greater than the preset collision angle, so that the randomly generated path will have a collision risk, causing the laying of the cable to be affected by obstacles;

[0032] The output end of the reminding and warning unit is connected to the input end of the information receiving unit and the alarm feedback unit.

[0033] Furthermore, the communication cable laying route analysis specifically includes the following steps:

[0034] S01: Obtaining geographic location information in the actual scene and establishing a two-dimensional model, and randomly generating a cable laying path according to the two-dimensional model;

[0035] S02: generating the total cable length required in the actual scene according to the information of the laying length of the cable in the established two-dimensional model and the ditch height in the actual scene;

[0036] S03: After the total length information of the cables in the actual scene and the randomly generated path information are imported into the platform, if the platform is detected to issue an alarm, the obstacle information in the actual scene and the established two-dimensional model scene is traversed and fed back to step S04;

[0037] S04: Obtain an information set of obstacles in the actual scene, extract the contour point information of the obstacles, and generate a contour curve based on the contour point information of the obstacles; if it is detected that any node on the contour curve has a collision risk with any node on the randomly generated path, modify the node on the path in the two-dimensional model.

[0038] In step S02, the cable laying length information of different terrain areas in the two-dimensional model is obtained as L={l1, l2, l3...l m} and terrain height information set Y = {y1, y2, y3...y m}, m refers to the terrain item; the terrain height information in the actual scene is obtained as H. If the terrain height h in the actual scene is obtained by comparison k Greater than the terrain height y of the corresponding area in the two-dimensional model k , and then the height difference is HY, then it is necessary to re-determine the length of the cable laid in the actual scene; if the terrain height h in the actual scene is obtained through comparison k Equal to the corresponding terrain height y in the two-dimensional model k , then the length of the cable laid in the actual scene is the same as the corresponding terrain height in the two-dimensional model;

[0039] A rectangular coordinate system is established, and the difference HY between the terrain height in the two-dimensional model and the actual terrain height is perpendicular to the cable lengths laid in different terrain areas in the two-dimensional model. The angle formed by the line connecting the corresponding terrain height in the actual scene and the corresponding terrain height in the two-dimensional model and the horizontal coordinate is θ, thereby obtaining the actual length to be laid in the actual scene;

[0040] According to the following formula:

[0041] In actual scenarios, the length of the cable should be increased by Ml. k ;

[0042] Where: M refers to the length of the cable in the corresponding area in the actual scenario, and l k refers to the cable laying length of the k-th area, and h k refers to the actual terrain height of the k-th area, and y k refers to the terrain height of the two-dimensional model in the k-th area.

[0043] In step S04, obtain the contour point information of the obstacle, extract the contour point positions on the surface of the obstacle to establish a contour point function curve, and set Q1 = a1x1 2 +b1x1 + c1; obtain the nodes of the randomly generated cable laying path in the two-dimensional model, cut the two-dimensional model of the cable path into a two-dimensional model, establish a function curve according to the positions of the nodes in the two-dimensional model, and set it as Q2 = a2x2 2 +b2x2 + c2; if it is detected that Q1 = Q2, it means that any node on the set path in the two-dimensional model has an intersection with the formed obstacle curve, and then the nodes on the existing path in the two-dimensional model need to be moved; if it is detected that Q1 ≠ Q2, it means that any node on the set cable laying path in the two-dimensional model has no intersection with the formed obstacle curve, and there is no need to update the cable laying path in the two-dimensional model;

[0044] If there is an intersection, extract the contour nodes on the obstacle curve and the node information on the cable laying path in the two-dimensional model. If it is detected that the angle generated by the contour node and the node on the cable laying path on the horizontal axis is greater than the preset angle, it means that the collision risk is higher than the preset collision risk value; extract the intersection coordinate values of the cable path and the obstacle curve in the two-dimensional model, set it as W = (i, j), so that the vertical distance T between the latest node R = (e, f) after moving on the cable route and the intersection is T < TL, and any node on the moved cable path will not have an intersection with any node on the obstacle curve;

[0045]

[0046] Where: TL refers to the preset maximum vertical distance, a1, b1, c1 refer to the coefficients on the function curve Q1, and a2, b2, c2 refer to the coefficients on the function curve Q2.

[0047] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0048] Through the cable actual length analysis module, the present invention improves the positioning accuracy problem in the entire two-dimensional model by adjusting the actual length of the cable; solves the error problem generated in the actual measurement process, and reduces the efficiency problem of modifying the cable length twice;

[0049] Through the GPS precision adjustment module, the obstacles appearing in the two-dimensional model are compared with the obstacles in the actual scene, avoiding the risk of collision between the cable path and obstacles. By adjusting the nodes on the line path, the risk of collision between the cable path and the nodes on the obstacles can be avoided, solving the problem of complex cable path laying.

[0082] The output end of the reminding and warning unit is connected to the input end of the information receiving unit and the alarm feedback unit.

[0083] Furthermore, the communication cable laying route analysis specifically includes the following steps:

[0084] S01: Obtaining geographic location information in the actual scene and establishing a two-dimensional model, and randomly generating a cable laying path according to the two-dimensional model;

[0085] S02: generating the total cable length required in the actual scene according to the information of the laying length of the cable in the established two-dimensional model and the ditch height in the actual scene;

[0086] S03: After the total length information of the cables in the actual scene and the randomly generated path information are imported into the platform, if the platform is detected to issue an alarm, the obstacle information in the actual scene and the established two-dimensional model scene is traversed and fed back to step S04;

[0087] S04: Obtain an information set of obstacles in the actual scene, extract the contour point information of the obstacles, and generate a contour curve based on the contour point information of the obstacles; if it is detected that any node on the contour curve has a collision risk with any node on the randomly generated path, modify the node on the path in the two-dimensional model.

[0088] In step S02, the cable laying length information of different terrain areas in the two-dimensional model is obtained as L={l1, l2, l3...l m} and terrain height information set Y = {y1, y2, y3...y m}, m refers to the terrain item; the terrain height information in the actual scene is obtained as H. If the terrain height h in the actual scene is obtained by comparison k Greater than the terrain height y of the corresponding area in the two-dimensional model k , and then the height difference is HY, then it is necessary to re-determine the length of the cable laid in the actual scene; if the terrain height h in the actual scene is obtained through comparison k Equal to the corresponding terrain height y in the two-dimensional model k , then the length of the cable laid in the actual scene is the same as the corresponding terrain height in the two-dimensional model;

[0089] A rectangular coordinate system is established, and the difference HY between the terrain height in the two-dimensional model and the actual terrain height is perpendicular to the cable lengths laid in different terrain areas in the two-dimensional model. The angle formed by the line connecting the corresponding terrain height in the actual scene and the corresponding terrain height in the two-dimensional model and the horizontal coordinate is θ, thereby obtaining the actual length to be laid in the actual scene;

[0090] According to the following formula:

[0091] In actual scenarios, the length of the cable should be increased by Ml. k ;

[0092] Where: M refers to the length of the cable in the corresponding area in the actual scenario, and l k refers to the cable laying length of the k-th area, and h k refers to the actual terrain height of the k-th area, and y k refers to the terrain height of the two-dimensional model in the k-th area;

[0093] When GPS positioning, due to network accuracy and terrain reasons in the actual scenario, the positioning accuracy of GPS may not be consistent with the positioning accuracy in the two-dimensional model. For example, the terrain height information in the actual scenario is not consistent with the terrain height information in the two-dimensional model. Therefore, usually, the terrain height information in the actual scenario is compared with the terrain height information in the two-dimensional scenario to prevent the need for secondary calculation of the cable laying length in the two-dimensional model when they are inconsistent; in the above process, the formula is set. Through this formula, the cable laying length required in the actual scenario can be judged, thereby solving the problem of inaccurate cable length.

[0094] In step S04, obtain the contour point information of the obstacle, extract the contour point positions on the surface of the obstacle to establish a contour point function curve, and set Q1 = a1x1 2 + b1x1 + c1; obtain the nodes of the randomly generated cable laying path in the two-dimensional model, cut the two-dimensional model of the cable path into a two-dimensional model, establish a function curve according to the positions of the nodes in the two-dimensional model, and set it as Q2 = a2x2 2 + b2x2 + c2; if it is detected that Q1 = Q2, it means that any node on the set path in the two-dimensional model has an intersection with the formed obstacle curve, and then the nodes on the existing path in the two-dimensional model need to be moved; if it is detected that Q1 ≠ Q2, it means that any node on the set cable laying path in the two-dimensional model has no intersection with the formed obstacle curve, and there is no need to update the cable laying path in the two-dimensional model;

[0095] If there is an intersection, extract the contour nodes on the obstacle curve and the node information on the cable laying path in the two-dimensional model. If it is detected that the angle generated by the contour node and the node on the cable laying path on the horizontal axis is greater than the preset angle, it means that the collision risk is higher than the preset collision risk value; extract the intersection coordinate values of the cable path and the obstacle curve in the two-dimensional model, set it as W = (i, j), so that the vertical distance T between the moved latest node R = (e, f) on the cable route and the intersection is less than TL, and any node on the moved cable path will not have an intersection with any node on the obstacle curve;

[0096]

[0097] Where: TL refers to the preset longest vertical distance, a1, b1, c1 refer to the coefficients on the function curve Q1, and a2, b2, c2 refer to the coefficients on the function curve Q2;

[0098] When planning the cable route, it is inevitable that construction excavation or new obstacles will appear on the planned cable route due to weather reasons. If an obstacle occurs, it is necessary to determine the impact of the immovable obstacle on the cable laying path. Therefore, the vertical distance T set here is the distance that the node on the path in the two-dimensional model needs to be moved after determining that there will be an impact, so as to prevent the line radiation path from colliding with the obstacle and avoid increasing the risk of collision.

[0099] Example 1: Obtaining the cable laying length information of the k-th terrain area design in the two-dimensional model as l k = 15m and the kth terrain height information set y k =O, by comparison, we can get the terrain height h in the actual scene k =30 is greater than the terrain height y of the corresponding area in the two-dimensional model k =0, and the height difference is HY=30, then the length of the cable laid in the actual scene needs to be re-determined;

[0100] A rectangular coordinate system is established, and the difference between the terrain height in the two-dimensional model and the actual terrain height HY=30 is perpendicular to the length of the cables laid in different terrain areas in the two-dimensional model. The angle formed by the line connecting the corresponding terrain height in the actual scene and the corresponding terrain height in the two-dimensional model and the horizontal coordinate is θ, thereby obtaining the actual length that should be laid in the actual scene;

[0101] According to the following formula:

[0102] In actual scenarios, the length of the cable should be increased by Ml. k =34-15=19m.

[0103] Example 2: Obtaining the cable laying length information designed for the kth terrain area in the two-dimensional model as l k = 15m and the kth terrain height information set y k =O, by comparison, we can get the terrain height h in the actual scene k =0 is equal to the terrain height y of the corresponding area in the two-dimensional model k =0, and the height difference is HY=0, then the length of the cable laid in the actual scene needs to be re-determined;

[0104] A rectangular coordinate system is established, and the difference between the terrain height in the two-dimensional model and the actual terrain height HY=0 is perpendicular to the length of the cables laid in different terrain areas in the two-dimensional model. The angle formed by the line connecting the corresponding terrain height in the actual scene and the corresponding terrain height in the two-dimensional model and the horizontal coordinate is θ, thereby obtaining the actual length to be laid in the actual scene;

[0105] According to the following formula:

[0106] The length of the cable in the actual scene is the same as the length of the corresponding cable in the 2D model, and there is no need to increase the cable length in the actual scene.
