Description

Technical Field

[0001] The invention belongs to the technical field of measuring the interval between a high-voltage cable and a tree crown, and in particular relates to a method for measuring the interval between a high-voltage cable and a tree crown. Background Art

[0002] In the power transmission and distribution system, high-voltage cables need to maintain a certain safe distance from the surrounding environment, especially vegetation, during installation and operation. Tree crowns are one of the common vegetation obstacles, and sufficient spacing must be maintained between them and high-voltage cables to avoid problems such as wear, damage or short circuit caused by vegetation. Measuring the distance between high-voltage cables and tree crowns through technical means can help power system managers better plan cable layout and vegetation management to ensure safe and stable operation of the system.

[0003] Under the current technical background, in the early planning stage of high-voltage cable laying, in order to ensure the accuracy of the line tree distance measurement, a large number of monitoring equipment need to be set up. After the cable is officially put into operation, the monitoring equipment still needs to monitor the growth of trees for a long time to ensure the working environment of the cable, resulting in a large amount of manpower and equipment cost consumption. When the equipment fails, due to the large number of deployed equipment, it is necessary to confirm the equipment with errors, which consumes manpower again. Therefore, how to make the cable tree distance measurement cost and cable tree distance measurement accuracy compatible is the current technical problem;

[0004] To this end, we propose a method to measure the distance between high-voltage cables and tree crowns. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention aims to provide a method for measuring the interval between a high-voltage cable and a tree crown.

[0006] The technical problems to be solved by the present invention are:

[0007] How to reduce the workload and cost of cable tree distance measurement while ensuring measurement accuracy.

[0008] In order to achieve the above object, the present invention adopts the following technical solutions:

[0009] 1. A method for measuring the interval between a high-voltage cable and a tree crown, characterized in that the method steps include:

[0010] Step S101, the equipment installation module installs the monitoring equipment required for tree distance measurement. After the monitoring equipment is installed, the information acquisition module obtains the tree distribution information of the expected installation area and sends it to the tree analysis module via the server;

[0011] Step S102, the tree analysis module analyzes the growth of trees in the expected erection area, divides the expected erection area into a number of fan-shaped areas, and after successively completing the area type determination of each fan-shaped area, the tree analysis module sends the area type of the fan-shaped area in the expected erection area to the site selection module via the server;

[0012] Step S103, the site selection module makes a final decision on the site selection of the cable tower, and the connection result of the cable laying route obtained by the selection is sent to the operation terminal via the server. The operation terminal selects the connection result as a connectable cable laying route, and connects several cable laying routes in the form of end-to-end connection, and the intersection of the cable laying routes is the actual installation position of the cable tower;

[0013] Step S104, after the cable tower is erected and connected to the high-voltage cable, a monitoring device is installed on the cable tower, and the information acquisition module obtains the real-time cable data of the high-voltage cable and sends it to the tree distance analysis module via the server. The tree distance analysis module analyzes the interval between the high-voltage cable and the tree, obtains the contact type of the trees in the fan-shaped area and sends it to the countermeasure terminal via the server. The countermeasure terminal takes countermeasures for the overly high trees around the high-voltage cable.

[0014] Furthermore, in step S101, the equipment installation process of the equipment installation module is as follows:

[0015] Install monitoring equipment at the expected location of the cable tower, and the location of the monitoring equipment should be higher than the height of the trees;

[0016] A circular area with the estimated installation location of the cable tower as the center and the critical monitoring distance of the monitoring equipment as the radius.

[0017] Furthermore, the tree distribution information includes the number of trees in the estimated erection area and the tree base position, crown position, tree height, number of tree branches, and branch extension width of each branch of each tree.

[0018] Furthermore, in step S102, the analysis process of the tree analysis module is as follows:

[0019] Divide the planned installation area into a number of fan-shaped areas and number the fan-shaped areas in clockwise order;

[0020] Obtain the number of trees in each fan-shaped area and the tree base position, tree height, tree branch number and branch extension width of each tree in the fan-shaped area;

[0021] Calculate the tree growth density value of each sector area, and compare the tree growth density value of the sector area with the standard density range;

[0022] If the tree growth density value of the sector area belongs to the standard density range, the area type of the sector area is determined to be a cable passage area;

[0023] If the tree growth density value in the sector-shaped area does not belong to the standard density range, the area type of the sector-shaped area is determined to be a cable-free area.

[0024] Furthermore, in step S103, the module working process of the site selection module is as follows:

[0025] Get the area type of the fan-shaped area in the expected installation area;

[0026] If the area types of the fan-shaped areas in the planned installation area are all cable-prohibited areas, the planned installation area will be eliminated;

[0027] If the area type of any sector area in the expected installation area is a cable passage area, the expected installation positions of adjacent cable towers are used as endpoints to connect the cable laying routes, and the sector areas of the expected installation area are marked as passage areas and the area type of the passage areas is obtained;

[0028] If the area type of any passable area is a cable prohibited area, the connection result of the cable laying route is determined to be unconnectable;

[0029] If the area types of the passable areas are all cable passable areas, the connection result of the cable laying route is determined to be connectable.

[0030] Furthermore, the real-time cable data includes the incoming end point coordinates, outgoing end point coordinates and cable drop distance of the segment cable.

[0031] Furthermore, in step S104, the analysis process of the tree distance analysis module specifically includes:

[0032] Obtain the incoming end point coordinates, outgoing end point coordinates and cable drop distance of the segment cable;

[0033] Draw a line between the coordinates of the incoming line endpoint and the outgoing line endpoint and use the corresponding line as the axis;

[0034] A cylinder is constructed with the cable drop distance as the radius, and all coordinates on the surface and inside of the cylinder are recorded as contact risk coordinates.

[0035] Furthermore, in step S104, the analysis process of the tree distance analysis module specifically includes:

[0036] Obtain the crown position of each tree in the fan-shaped area and mark the crown position with three-dimensional coordinates;

[0037] Traverse and compare the crown position of each tree in the fan-shaped area with the contact risk coordinates;

[0038] When the abscissa of the crown position is not equal to the abscissa of the contact risk coordinate or the ordinate of the crown position is not equal to the ordinate of the contact risk coordinate, the contact type of the tree is determined to be a normal tree.

[0039] Furthermore, in step S104, the analysis process of the tree distance analysis module specifically includes:

[0040] When the abscissa of the crown position is equal to the abscissa of the contact risk coordinate and the ordinate of the crown position is equal to the ordinate of the contact risk coordinate;

[0041] If the vertical coordinate of the crown position is greater than or equal to the vertical coordinate of the contact risk coordinate, the contact type of the tree is determined to be a contact risk tree;

[0042] If the vertical coordinate of the crown position is less than the vertical coordinate of the contact risk coordinate, the contact type of the tree is determined to be a normal tree.

[0043] Furthermore, in step S104, the module operation process of the countermeasure terminal is as follows:

[0044] Obtain the contact type of the trees in the fan-shaped area. If the contact type of the tree is a contact risk tree, arrange staff to go to the corresponding location to perform tree pruning operations or adjust the line of the high-voltage cable;

[0045] If the contact type of the tree is a normal tree, no additional operations are performed.

[0046] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0047] 1. The present invention firstly installs the monitoring equipment required for tree distance measurement through the equipment installation module. After the monitoring equipment is installed, the information acquisition module is used to obtain the tree distribution information of the expected installation area. The tree analysis module is used to analyze the tree growth in the expected installation area to obtain the area type of the fan-shaped area in the expected installation area. The site selection module is used to make a final decision on the site selection of the cable tower, and the connection result of the cable laying route is obtained. The operation terminal selects the connection result as the connectable cable laying route to complete the line connection work;

[0048] 2. After the cable tower is erected and the high-voltage cable is connected, the present invention also obtains real-time cable data of the high-voltage cable through the information acquisition module, and then uses the tree distance analysis module to analyze the interval between the high-voltage cable and the tree to obtain the contact type of the trees in the fan-shaped area, and finally uses the countermeasure terminal to take immediate measures against the over-high trees around the high-voltage cable. The present invention realizes accurate measurement of the cable tree distance while controlling the cable tree distance measurement cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, not 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.

[0060] Example 1: Please refer to Figure 1-8 As shown, the technical solution provided by the present invention is: a method for measuring the interval between a high-voltage cable and a tree crown, and the method is specifically as follows:

[0061] Step S101, the equipment installation module installs the monitoring equipment required for tree distance measurement. After the monitoring equipment is installed, the information acquisition module obtains the tree distribution information of the expected installation area and sends it to the tree analysis module via the server;

[0062] Step S102, the tree analysis module analyzes the growth of trees in the expected erection area, divides the expected erection area into a number of fan-shaped areas, and after successively completing the area type determination of each fan-shaped area, the tree analysis module sends the area type of the fan-shaped area in the expected erection area to the site selection module via the server;

[0063] Step S103, the site selection module makes a final decision on the site selection of the cable tower, and the connection result of the cable laying route obtained by the selection is sent to the operation terminal via the server. The operation terminal selects the connection result as a connectable cable laying route, and connects several cable laying routes in the form of end-to-end connection, and the intersection of the cable laying routes is the actual installation position of the cable tower;

[0064] Step S104, after the cable tower is erected and connected to the high-voltage cable, a monitoring device is installed on the cable tower, and the information acquisition module obtains the real-time cable data of the high-voltage cable and sends it to the tree distance analysis module via the server. The tree distance analysis module analyzes the interval between the high-voltage cable and the tree, obtains the contact type of the trees in the fan-shaped area and sends it to the countermeasure terminal via the server. The countermeasure terminal takes countermeasures for the overly high trees around the high-voltage cable.

[0065] The method involves a server, wherein the server is connected with an equipment installation module, an information acquisition module, a tree analysis module, a site selection module, an operation terminal, a tree distance analysis module and a countermeasure terminal;

[0066] In this embodiment, high voltage cables are connected between adjacent cable towers, and the cable connectors of the high voltage cables are connected to the cable racks of the cable towers. Figure 3 As shown, the high voltage cable is segmented according to the cable tower to obtain cable segments, and both ends of the cable segments are cable connectors;

[0067] See also Figure 4 As shown, the equipment installation module is used to install the monitoring equipment required for tree distance measurement. The equipment installation process is as follows:

[0068] Monitoring equipment is installed at the expected installation location of the cable tower, and the expected installation area is delineated according to the monitoring range of the monitoring equipment, such as Figure 4 As shown, the expected installation area is a circular area with the expected installation position of the cable tower as the center and the critical monitoring distance of the monitoring equipment as the radius;

[0069] It should be specifically noted that in order to ensure that the monitoring equipment can fully and accurately obtain the growth of trees around the cable tower, the monitoring equipment should be installed at a location much higher than the height of the trees. Therefore, the monitoring equipment is installed on drones, temporary brackets, pillars, etc. to ensure that the information acquisition work is carried out normally. The monitoring equipment includes but is not limited to monitoring probes, infrared rangefinders, and camera pan / tilts, etc.;

[0070] After the monitoring equipment is installed, please refer to Figure 5 As shown, the information acquisition module is used to obtain the tree distribution information of the expected erection area and send it to the server. The server sends the tree distribution information of the erection area to the tree analysis module and the tree distance analysis module. The tree distribution information includes the number of trees in the expected erection area and the tree bottom position, crown position, tree height, number of tree branches and branch extension width of each branch of each tree, wherein the tree bottom position is the position coordinate of the tree root on the ground, and the branch extension width is the distance between the branch end point position of the tree and the tree trunk. In this embodiment, the branch end point position farthest from the tree trunk among the several branches of the tree is taken as the branch extension width of the tree, as shown in FIG. Figure 5 As shown, a three-dimensional coordinate system is constructed with the estimated installation position of the cable tower, that is, the center of the estimated hypothetical area, as the origin, and the bottom position of the tree is determined according to the three-dimensional coordinate system.

[0071] See also Figure 6 As shown, the tree analysis module is used to conduct a comprehensive analysis of the growth of trees in the expected erection area. The specific analysis process is as follows:

[0072] like Figure 6 As shown, the planned installation area is divided into 8 sectors, and the sectors are numbered in clockwise order;

[0073] Obtain the number of trees Nr in each sector area, as well as the tree base position, tree height GDi, tree branch number ZCi and branch extension width ZKi of each tree in the sector area, where i is the tree number, the upper limit of i is equal to the number of trees in the expected erection area, r is the sector area number, and the values ​​of r include 1, 2, 3, 4, 5, 6, 7, 8, N1+N2+N3+N4+N5+N6+N7+N8=the number of trees N in the erection area;

[0074] The tree bottom distance SJi between adjacent data is obtained according to the tree bottom position. Since there are two tree numbers in the tree bottom distance, the smaller number is selected in this embodiment to mark the two tree bottom distances;

[0075] The tree growth density value MDr of each fan-shaped area is calculated according to the formula. The specific formula is as follows:

[0076] ;

[0077] Among them, e is a natural constant, a1, a2 and a3 are weight coefficients with fixed values, a1 is the tree spacing weight, a2 is the tree size weight, and a3 is the tree branch weight. It can be understood that the value corresponding to a1 is the horizontal spacing between adjacent trees. In the actual calculation process, the spacing between tree i and tree i' is the shortest;

[0078] Compare the tree growth density values ​​in the fan-shaped area with the standard density range;

[0079] If the tree growth density value of the sector area belongs to the standard density range, the area type of the sector area is determined to be a cable passage area;

[0080] If the tree growth density value in the sector area does not belong to the standard density range, the sector area is determined to be a cable-free zone;

[0081] It should be specifically stated that when the tree growth density value belongs to the standard density interval, the tree growth density in the corresponding fan-shaped area meets the cable passage standard, and the cable is not likely to come into contact with the trees and their branches when passing through the fan-shaped area; when the tree growth density value does not belong to the standard density interval, the tree growth density in the corresponding fan-shaped area cannot meet the cable passage standard, and the cable is likely to come into contact with the trees and their branches when passing through the fan-shaped area;

[0082] After completing the regional type determination of each sector area in turn, the tree analysis module sends the regional type of the sector area in the expected erection area to the server, and the server sends the regional type of the sector area in the expected erection area to the site selection module;

[0083] See also Figure 7 As shown, the site selection module is used to make a final decision on the site selection of the cable tower. The working process of the module is as follows:

[0084] Get the area type of the fan-shaped area in the expected installation area;

[0085] If the area types of the fan-shaped areas in the planned installation area are all cable-prohibited areas, the planned installation area will be eliminated;

[0086] If the area type of any sector area in the expected installation area is a cable passage area, the cable laying route is obtained by connecting the expected installation positions of adjacent cable towers as endpoints, and the sector areas in the expected installation area are marked as passage areas. Figure 7 As shown, after the cable laying route is connected, it passes through at least two fan-shaped areas in the planned installation area;

[0087] Get the area type of the pass area;

[0088] If the area type of any passable area is a cable prohibited area, the connection result of the cable laying route is determined to be unconnectable;

[0089] If the area types of the passable areas are all cable passable areas, the connection result of the cable laying route is determined to be connectable;

[0090] The site selection module sends the connection result of the cable laying route to the server, and the server sends the connection result of the cable laying route to the operation terminal;

[0091] See also Figure 8 As shown, the preferred connection result of the operation terminal is a connectable cable laying route, and several cable laying routes are connected in an end-to-end form, thereby completing the interconnection operation of the high-voltage cable, and the intersection of the cable laying routes is the actual installation position of the cable tower.

[0092] In this embodiment, after the cable tower is erected and connected to the high-voltage cable, a monitoring device is set on the cable tower. The information acquisition module is also used to obtain real-time cable data of the high-voltage cable and send it to the server. The server sends the real-time cable data of the high-voltage cable to the tree distance analysis module. The real-time cable data includes the coordinates of the incoming end point of the segment cable, the coordinates of the outgoing end point and the cable drop distance. Figure 8 As shown, the incoming line endpoint coordinates are the cable joint position coordinates of the segment cable corresponding to the current input end, and the outgoing line endpoint coordinates are the cable joint position coordinates of the segment cable corresponding to the current output end. A line is connected with the incoming line endpoint coordinates and the outgoing line endpoint coordinates as endpoints, and the midpoint of the connecting line and the midpoint of the segment cable in the natural drooping state are taken. The vertical height difference between the two points is taken as the cable drooping distance.

[0093] The tree distance analysis module is used to analyze the distance between the high voltage cable and the trees. The analysis process is as follows:

[0094] Obtain the incoming line endpoint coordinates, outgoing line endpoint coordinates and cable drop distance of the segment cable, draw a line between the incoming line endpoint coordinates and the outgoing line endpoint coordinates and use the corresponding line as the axis, construct a cylinder with the cable drop distance as the radius, and record all coordinates on the surface and inside of the cylinder as contact risk coordinates FX (Xk, Yk, Zk), where k is the coordinate sequence number, k is a positive integer, where Xk is the horizontal coordinate of the contact risk coordinate in the corresponding three-dimensional coordinate system, Yk is the vertical coordinate of the contact risk coordinate in the corresponding three-dimensional coordinate system, and Zk is the vertical coordinate of the contact risk coordinate in the corresponding three-dimensional coordinate system;

[0095] Get the crown position of each tree in the fan-shaped area, and mark the crown position SGi (XGi, YGi, ZGi) with three-dimensional coordinates, where XGi is the horizontal coordinate of the crown position of the tree in the corresponding three-dimensional coordinate system, YGi is the vertical coordinate of the crown position of the tree in the corresponding three-dimensional coordinate system, and ZGi is the vertical coordinate of the crown position of the tree in the corresponding three-dimensional coordinate system;

[0096] Traverse and compare the crown position SGi (XGi, YGi, ZGi) of each tree in the fan-shaped area with the contact risk coordinates FX (Xr, Yr, Zr);

[0097] When XGi is equal to Xk and YGi is equal to Yk, if ZGi ≥ Zk, the contact type of the tree is determined to be a contact risk tree;

[0098] When XGi is equal to Xk and YGi is equal to Yk, if ZGi<Zr, the contact type of the tree is determined to be a normal tree;

[0099] If XGi is not equal to Xk or YGi is not equal to Yk, the contact type of the tree is determined to be a normal tree;

[0100] The tree distance analysis module sends the contact types of the trees in the fan-shaped area to the server, and the server sends the contact types of the trees in the fan-shaped area to the countermeasure terminal.

[0101] In this embodiment, the countermeasure terminal is used to immediately respond to over-high trees around the high-voltage cable. The working process of the module is as follows:

[0102] Obtain the contact type of the trees in the fan-shaped area. If the contact type of the tree is a contact risk tree, arrange staff to go to the corresponding location to perform tree pruning operations or adjust the line of the high-voltage cable;

[0103] If the contact type of the tree is a normal tree, no additional operations are performed;

[0104] In this application, if corresponding calculation formulas appear, the above calculation formulas are all dimensionless and take their numerical calculations. The weight coefficients, proportional coefficients and other coefficients in the formulas are set to a result value obtained by quantifying each parameter. The size of the weight coefficient and the proportional coefficient can be determined as long as it does not affect the proportional relationship between the parameter and the result value.
