Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a transmission line under-affected tree automatic display device that automatically informs in a predetermined format whether or not the distance between a transmission line and a tree is appropriately maintained as a tree near the transmission line grows.
[0002]
[Prior art]
In general, a transmission line is constructed by laying a steel tower in a mountain and having a predetermined slack. For this reason, the distance between the power transmission line and the tree cannot be maintained properly due to the growth of the tree near the power transmission line (hereinafter referred to as a transmission line troubled tree).
[0003]
In the past, a troubled tree under the power transmission line was previously selected by a power company appointed worker who actually went under the power transmission line and touched the power transmission line when the power transmission line underwhelmed the tree. (Including trees with fear), and felled as needed.
[0004]
For this reason, a lot of workers are required to check, and the check takes a very long time.
[0005]
Therefore, in recent years, it is sometimes checked whether a tree touches a power transmission line from a three-dimensional photograph obtained by flying over the power transmission line with an aircraft.
[0006]
In this check, a person calculates the height of a tree from a three-dimensional photograph, plots the height of the tree on a drawing in which the height of the transmission line is written, and then writes a range in which the transmission line fluctuates due to wind or the like.
[0007]
Then, it was checked whether or not there are any trees that fall within this range or trees that fall within the aforementioned range in the near future.
[0008]
[Problems to be solved by the invention]
However, from the three-dimensional photographs of forests obtained by aircraft, it is necessary for humans to calculate the height of each hindrance tree near the transmission line and to write the range where the transmission line fluctuates. There was a problem that it took a huge amount of time to find the troubled trees.
[0009]
Therefore, it is desirable to have an automatic transmission line under-affected tree display device that automatically determines and notifies the troubled trees near the transmission line from the three-dimensional data obtained by the aircraft.
[0010]
In addition, automatic detection of troubled trees under the transmission line can be automatically performed in a short time by automatically identifying the troubled tree near the lower part of the transmission line from the three-dimensional data obtained by installing the laser ranging device on the aircraft (including helicopter). A display device is desirable.

[0015]
<Details of each part>
In the database 3, three-dimensional data such as trees and steel towers obtained by mounting a laser range finder on an aircraft (including a helicopter) and three-dimensional data obtained by the aircraft are stored in advance in a hierarchical structure. In addition, a three-dimensional image of a forest obtained by an aircraft is stored.
[0016]
For example, as shown in FIG. 2, the route Ai (i; a, b, c,...) Of the power transmission line, the terrain data Gi (i; a, b, c,...) Of the route Ai, and the route Ai.

Further, the tree information h includes each tree position (hix, hiy, hiz, i; a, b, c,...) In the image ki and terrain data (ix, iy, iz, i; a, b, c, ...). These pieces of information are stored separately for each route (Aa, Ab,...).
[0018]
Furthermore, the database 3 stores the separation distance information Ri obtained by the transmission line-tree calculation processing unit 19 in a hierarchical manner as shown in FIG. The separation distance information Ri includes the span information Bi (i; a, b, c,...) And the transmission line state information Li (i; a, b) of the route Ai (i; a, b, c,...). , C,...), The tree position hi of the span information Bi, and the separation distance mi (i; a1, a2,..., B1, b2,...) Are stored in association with each other. These pieces of information are stored separately for each route.
[0019]
The multi-window management unit 6 manages each program and simultaneously opens a plurality of desired screens on the display unit 4. Further, the position on the screen instructed by the mouse 5 is sent to the setting information reading processing unit 7.
[0020]
The setting information reading processing unit 7 uses the multi-window management unit 6 to display a display format selection screen such as a route, a span, a plan view, a cross-sectional view, a photographic image, and a transmission line state condition, a growth rate update screen, and logging information setting. A screen, a total screen setting screen, and the like are displayed, and a flag indicating the condition of the screen from the position on the screen designated by the mouse 5 is set in the flag register on these screens.
[0021]
The above-mentioned power transmission line condition is a condition for setting at least whether to transmit the maximum power transmission to the power transmission line, whether to consider the influence of wind, and the like.
[0022]
The processing mode determination processing unit 8 includes a data reading unit 10, a three-dimensional image display processing unit 14, a vertical drawing generation processing unit 16, a sectional view generation processing unit 17, a plan view generation processing unit 18, depending on the type of flag in the flag register. Either the power transmission line-tree calculation processing unit 19 or the tree information update processing unit 20 is activated, and the setting contents of the flag register are set in the processing unit.
[0023]
When the route Ai and the span Bi are specified, the data reading unit 10 stores the separation distance information Ri and the transmission line-tree information Ji related to the span of the route in the main memory 11, and three-dimensionally. The image is stored in the image memory 12.
[0024]
The projection processing unit 13 has a three-axis coordinate system, projects X and Y coordinate values onto an XY coordinate system, projects X and Z coordinate values onto an X-Z coordinate system, and Y, Z The coordinate values are projected onto the YZ coordinate system.
[0025]
The three-dimensional image display processing unit 14 displays the three-dimensional image stored in the image memory 12 using the multi-window management unit 6.
[0026]
The vertical drawing generation processing unit 16 sends the hx and hy of all the tree information h of the separation distance information Ri corresponding to the span Bi of the route Ai of the main memory 11 to the projection processing unit 13 in accordance with the vertical sectional view display command. The symbols and codes are assigned to the coordinates projected and projected onto the X-Z coordinate system by the projection processing unit 13 and displayed according to the color based on the determination result.
[0027]
At the same time, the power transmission line-tree calculating unit 19 is activated to determine the curve of the power transmission line connecting the steel towers according to the setting conditions of (1), (2), and (3), which will be described later. It is set in the projection processing unit 13, projected onto the ordinate system, and displayed together with the tree position.
[0028]
In response to the sectional view display command, the sectional view generation processing unit 17 reads the vertical cursor position of the displayed plan view and sets the sectional coordinates (hy, hz) of the tree information h at the cursor position in the projection processing unit 13. Then, the projection processing unit 13 assigns and displays symbols or symbols to the coordinates projected on the YZ coordinate system, and displays them by color based on the determination result.
[0029]
At the same time, the power transmission line-tree calculating unit 19 is activated to obtain a curve of the power transmission line connecting the steel towers according to the setting conditions (1), (2), and (3) described later, and the obtained curve is projected. It is set in the unit 13, projected onto the ordinate system, and displayed together with the tree position.
[0030]
Projection of this curve projects a cross-sectional view of a normal power transmission tower or a worst-case steel tower or both.
[0031]
When the transmission line is shaken during normal power transmission, a semicircle centered on the fulcrum of the cross section of the steel tower is obtained and projected. When the wind is considered at the worst, the fulcrum of the steel tower is extended based on a predetermined condition, and a semicircle centered on the fulcrum at this time is obtained and projected.
[0032]
The transmission line-tree calculation processing unit 19 reads the tree position hi of the span Bi and the pylon position of the transmission line from the database 3, obtains a curve of the transmission line connecting the pylons, and is separated from the tree position hi. Find the distance in three dimensions. These pieces of information are stored in the database 3 in the predetermined format shown in FIG.
[0033]
This separation distance is obtained according to the transmission line state setting conditions described above. For example,
(1) When the maximum power is not supplied to the transmission line and it is set not to consider the influence of wind, it is simply obtained as the separation distance between the tree and the transmission line.
[0034]
(2) When the maximum power is not supplied to the transmission line and the effect of wind is taken into consideration, the distance between the tree and the transmission line when the transmission line during normal power transmission is shaken with the maximum wind is obtained.
[0035]
(3) If it is set that the maximum power is supplied to the transmission line (also called the worst) and the effect of wind is not taken into account, the maximum power is sent to the transmission line and relaxed, and the tree and the transmission line are separated. Find the distance.
[0036]
Moreover, the transmission line-tree calculation processing unit 19 sets the curves of the transmission lines connecting the steel towers to the above-described (1), (2), and (3) when displaying a plan view, a cross-sectional view, and a longitudinal view. According to the conditions, the obtained curve is set in the projection processing unit 13, projected onto the plane coordinate system, the cross-sectional coordinate system, or the ordinate system, and displayed together with the tree position.
[0037]
In particular, in the display of the cross-sectional view, when the transmission line is shaken during normal power transmission, a semicircle centered on the fulcrum of the cross section of the steel tower is obtained. In the worst case, when the wind is considered, the fulcrum of the steel tower is extended based on a predetermined condition, and a semicircle centered on the fulcrum at this time is obtained.
[0038]
Further, when the update of the tree information h is notified, the tree information is allocated from the database 3, and the separation distance on the three axes between the transmission line and the tree is obtained based on the information, and the distance between the route and the diameter is correlated. Stored in the database 3.
[0039]
Moreover, the risk level described below is assigned to the above-mentioned separation distance. For example, the separation distance of any surface component on the XY axis plane (plane), X-Z axis plane (vertical plane), and Y-Z axis plane (horizontal plane) is within a predetermined number of weeks on the transmission line. Is assigned to red, purple is assigned to the transmission line within a few months, and green is assigned to other tree information h.
[0040]
That is, in the database 3, the distance between the transmission lines of the separation distance information Ri according to the conditions set on the transmission line state setting screen is divided into three axial plane components and stored, and the determination result of the three axial components is stored. Is done.
[0041]
The tree information update processing unit 20 searches the database 3 for the tree information h of the set track Ai and span Bi, and updates the tree height based on the input date. When logging is set, the logging length is subtracted from the tree height of the tree information.
[0042]
The projection processing unit 13 has a three-axis coordinate system, projects X and Y coordinate values onto an XY coordinate system, projects X and Z coordinate values onto an X-Z coordinate system, and Y, Z The coordinate values are projected onto the YZ coordinate system.
[0043]
The operation of the power transmission line lowering tree automatic display device configured as described above will be described with reference to the flowcharts of FIGS. In this flowchart, the process of generating a plan view will be emphasized and each process will be described in a series of flows. Further, the transmission line-tree information Ji is assumed to be Ja, and the separation distance information Ri is assumed to be Ra.
[0044]
First, the setting information calculation processing unit 73 is configured to select a route, span, plan view, cross-sectional view, photographic image, power transmission line condition, etc., a setting screen (not shown), a growth rate update screen, a logging information setting screen, A setting screen such as a total screen setting screen is displayed (S1).
[0045]
Next, it is determined whether or not the setting is completed (S2). If it is determined that the setting is completed, the transmission line-tree calculation processing unit 19 sets the distance Ba of the route Aa set by the mouse 5 on the setting screen. The transmission line-tree information Ja is allocated from the database 3 (S3), a risk determination process is performed based on the transmission line-tree information Ja, and the processing result is stored in the database 3 as shown in FIG. 3 (S4). . The calculation process between the conductive wire and the tree in step S4 is performed by inputting a distance calculation instruction.
[0046]
The power transmission line-tree information Ja is obtained by converting the height of a tree or the like measured by the laser distance measuring device and the plane position into three-dimensional coordinates and storing them.
[0047]
The above-described determination process is a process for obtaining the separation distance of any one of the above (1), (2), and (3). If there is a possibility that the distance on the surface is closer to the power transmission line than a predetermined distance, for example, the XY axis surface (plane), the X-Z axis surface (vertical surface), the Y-Z axis surface (horizontal surface) If the separation distance of any surface component in is close to the transmission line within a few weeks, red is assigned, purple is assigned to the transmission line within a few months, and green is assigned to the other tree information ha .
[0048]
In FIG. 3, the transmission line distance ma1x is the X-axis component separation distance, the transmission line distance ma1y is the Y-axis component separation distance, and the transmission line distance ma1z is the Z-component separation distance. The aforementioned separation distance calculation will be described later with reference to the drawings.
[0049]
Next, the data reading unit 10 loads the distance information Ra of the range Ba of the route Aa stored in the database 3 as the processing result of the transmission line-tree distance calculation processing unit 19 into the main memory 11. (S5).
[0050]
When the plan view display is selected by the mouse 5, the plan view generation processing unit 18 selects the X and Y coordinate values of each tree position hai (i; 1, 2,...) From the main memory 11 in the span Bi of the route Ai. Is set in the projection processing unit 13 and projected onto the plane coordinate system (S6).
[0051]
Then, a symbol or code is assigned to the projected plane coordinates and displayed according to color based on the determination result of the risk determination data Ea (S7). For example, if the distance between a transmission line and a tree is closer than a predetermined distance within a few weeks, red is displayed as a dangerous tree, purple is displayed for a tree close to the transmission line within a few months, and other trees are assigned and displayed. .
[0052]
That is, as shown in FIG. 6A, the plan view generation processing unit 18 calculates the distance tree of the above-mentioned (1), (2), and (3) for the dangerous tree between the steel towers 23a and 23b of the transmission line. The result after performing is displayed in different colors. In FIG. 6A, the circle mark is green, Δ is purple, and the x mark indicates a dangerous tree.
[0053]
Next, the processing mode determination processing unit 8 reads the setting information display format Ci set in the setting information reading processing unit 7 (S8), and determines whether to display a cross-sectional image (S9). If it is determined in step S9 that the cross-sectional image is not displayed, it is determined whether or not a longitudinal image is displayed (S10).
[0054]
If it is determined in step S10 that a vertical image is displayed, the vertical drawing generation processing unit 16 is activated.
[0055]
The longitudinal view generation processing unit 17 reads all the coordinates (hax, hay) of all the tree information ha of the separation distance information Ra of the main memory 11 in accordance with the longitudinal section display command (selection by the mouse) (S11). Then, the projection processing unit 13 projects the image on the X-Z coordinate system, displays the assigned symbol or code, and displays the longitudinal image displayed by color based on the determination result as shown in FIG. 6B. (S12). At this time, the transmission line-tree calculation unit 19 is activated at the same time, and the curve of the transmission line connecting the steel towers is obtained according to the setting condition of (1), (2), or (3), and the obtained curve Is set in the projection processing unit 13, projected onto the ordinate system, and displayed together with the tree position. In FIG. 6A, the dotted line is normal power transmission, and the worst time is a solid line.
[0056]
Next, the processing mode determination processing unit 8 determines whether or not the display format Ci indicates display of a three-dimensional image (S13).
[0057]
If it is determined in step S13 that a photographic image is displayed, the processing mode determination processing unit 8 activates the three-dimensional image display processing unit 14.
[0058]
The three-dimensional image display processing unit 14 reads a three-dimensional image corresponding to the span Ba of the route Aa from the image memory 12 (S14), and displays the three-dimensional image in a multiwindow (S15).
[0059]
If it is determined in step S10 that the image is not displayed vertically, the process proceeds to step S13.
[0060]
Furthermore, when it is determined in step S9 that the cross-sectional image is displayed, the cross-sectional view generation processing unit 17 is activated. The sectional view generation processing unit 17 reads the vertical cursor position 25 in the plan view as the sectional image display position Da (S16), the risk determination data Ea corresponding to the Da, and the sectional coordinates of the tree information ha at the cursor position 25 ( (hay, haz) is read and set in the projection processing unit 13 (S17), and a symbol or sign is assigned to the cross-sectional coordinates (hay, haz) projected onto the Y-Z coordinate system by the projection processing unit 13, and the determination result is displayed. The cross-sectional images displayed based on the colors are displayed (S18), and the process returns to step S13.
[0061]
As shown in FIG. 7, using the transmission line-tree calculation processing unit 19 described above, the broken image is generated as shown in FIG. And an image of the determined dangerous tree are generated and displayed.
[0062]
Next to this image, numerical values are displayed for the stillness, the sag during the horizontal swing, the temperature, and the swing angle.
[0063]
That is, as shown in FIG. 8, the configuration related to the display of the plan view, the cross-sectional view, and the longitudinal section is stored in advance in the database 3 as the transmission line-tree information Ji based on the data obtained by the laser distance measuring device or the like. Based on the transmission line-tree information Ji, the transmission line-tree calculation processing unit 19 obtains distance information Ri for each route and span in advance and stores it in the database 3.
[0064]
Then, after the data reading unit 10 loads all the specified route / diameter separation information Ri from the database 3 to the main memory 11, the plan view generation processing unit 18, the sectional view generation processing unit 17, or the vertical drawing generation processing unit 16 is projected onto the target coordinate system of the three-axis coordinate system using the projection processing unit 13 and displayed on the screen by the multi-window management unit 6.
[0065]
On the other hand, the tree information update processing unit 20 performs the processing shown in FIGS. First, the update process based on the growth rate in FIG. 9 will be described.
[0066]
First, the route and span table are displayed on the screen, and the route Aa and span Ba are selected (S20). Next, a screen for inputting the growth rate of each tree is displayed, and a growth rate corresponding to the type of the tree is input (S21).
[0067]
Then, the date to be updated with the growth rate is input (S22), the growth height of the tree is calculated from this date and the growth rate, and this growth height is added to the Z value of the tree information in the database 14 ( S23).
[0068]
Next, the separation calculation is performed again using the transmission line-tree calculation processing unit 19, and the separation distance of the database 3 is updated to the result (S24).
[0069]
The tree information update processing unit 20 also performs data update processing at the time of logging. First, the route and span table are displayed on the screen, and the route Ai and span Bi are selected (S30). Next, a logging method (root cutting, centering) or the like is input (S31). Then, the felling range is indicated with the mouse on the remote numerical diagram (S32). Next, the logging height is subtracted from the Z value of the tree information in the database 3 (S33).
[0070]
Next, the separation calculation is performed again using the transmission line-tree calculation processing unit 19, and the separation distance in the database 3 is updated to the result (S34).
[0071]
Next, the description of the transmission line-tree calculation processing unit 19 will be supplemented. The transmission line-tree calculation processing 19 is performed when the electric wire is stationary (normal power transmission, worst power transmission), when the electric wire sways (normal power transmission, worst power transmission), and when the tree falls.
[0072]
For example, when the electric wire is stationary, as shown in FIG. 11, the electric wire is stopped and the case 1 inside the fulcrum of the electric wire, the case 2 outside and under the fulcrum, and the outside of the fulcrum Thus, the separation distance r is determined linearly for the case 3 on the fulcrum.
[0073]
Further, when the electric wire is shaken (when the wind force is taken into consideration), as shown in FIG. 12, the case 1 is inside the electric wire deflection angle θ, and the outer side of the electric wire deflection angle θ is below the fulcrum. The separation distance r is determined linearly for the case 2 and for the case 3 outside the wire deflection angle θ and above the fulcrum.
[0074]
Further, regarding the fallen tree, as shown in FIG. 13, the distance between the fulcrum and the intersection of the trajectory line when the tree fell and the straight line connecting the root of the tree and the fulcrum of the transmission line is defined as the separation distance.
[0075]
In the above embodiment, the transmission line obtained from the data using the laser distance measuring device mounted on the aircraft, the steel tower position, and the tree position are used. However, the transmission line obtained from the three-dimensional image obtained by the aircraft. It may be a position, a steel tower position, or a tree position.
[0076]
【The invention's effect】
  As described above, according to the present invention,The operator can determine at a glance which tree will interfere with the transmission line.
[0078]
For this reason, it can be easily grasped from the computer screen by what time the troubled tree should be cut.
