In addition, when the pole utility pole X is a known utility pole, the location information acquisition unit 41 obtains the location information of the pole pole P from the map information database 31, the position information of the young number side utility pole A, and the position of the old number side pole P Information may be extracted and acquired.

  The correction information database 34 will be described in a third embodiment to be described later. In the first embodiment and the second embodiment to be described later, the correction information database 34 may not be provided.

  As described above, the attachment direction indicating device 10 includes the position information acquisition means 41, the overhead wire distance calculation means 42, the combined tension calculation means 44, the attachment direction instruction means 45, and the display device 14. The position information acquisition unit 41 acquires the position information of the pole utility pole X, the position information of the young number side utility pole A, and the position information of the old number side utility pole B. The overhead line distance calculating means 42 is configured by the support member 21 of the pole pole power pole X, which is supported by the support member 21 from the position information of the pole pole P, the position information of the young pole pole A, and the position information of the old pole pole B.

Next, FIG. 8 is a flowchart showing a method of assisting the attachment direction of the dispensed item executed by the attachment direction instructing device shown in FIG. 1 and the procedure of the attachment direction support program for causing the computer to realize this. FIG. 9 is an explanatory diagram illustrating a display example of position information displayed by the display device of the mounting direction indicating device illustrated in FIG. 1. FIG. 10 is an explanatory diagram showing a display example of the combined vector displayed by the display device of the attachment direction indicating device shown in FIG. FIG. 11 is an explanatory diagram for explaining the unbalanced stress acting on the base portion of the support member of the dispensed material according to the first embodiment. With reference to FIGS. 1 to 11 as appropriate, the operation of the attachment direction indicating device according to the first embodiment will be described along the flowchart of FIG. 8 is stored in the storage device 13, and the attachment direction indicating device 10 as a computer stores the paid-in item installation direction support program stored in the storage device 13. Read or write to the memory 12 for execution.

  The mounting direction indicating device 10 includes the position of the above-mentioned pole utility pole X, the position of the younger-numbered utility pole A on the younger side with respect to the pole pole P, and the old-numbered utility pole on the older side with respect to the pole pole P. When it is at the position B, the position measuring device 16 measures the position information on the pole utility pole X, the position information on the young power pole A, and the position information on the old power pole B. And the positional information acquisition means 41 acquires the positional information on the pole utility pole X, the positional information on the young number side electric pole A, and the positional information on the old number side electric pole B from the position measuring device 16 (step S11).

  As shown in FIG. 9, the position information of the pole utility pole X includes (latitude information latX, longitude information lonX, altitude information altX). The position information of the young electric pole A includes (latitude information latA, longitude information lonA, altitude information altA). The position information of the old telephone side utility pole B includes (latitude information latB, longitude information lonB, altitude information altB). And the positional information acquisition means 41 memorize | stores the positional information on the pole utility pole X, the positional information on the young electric pole A, and the positional information on the old electric pole B in the electric pole position information database 33 of the storage device 13.

  The overhead wire distance calculating means 42 shown in FIG. 3 is supported by the support member 21 of the pole utility pole X from the position information of the pole pole P, the position information of the young pole pole A, and the position information of the old pole B. The distance of the younger-numbered overhead line and the distance of the older-numbered overhead line are calculated (step S12). The distance between the young wire and the old wire is as follows: the distance between the utility poles A from the pole pole P to the young pole A, and the pole between the pole pole X and the old pole B side. The distance is almost the same. For this reason, the overhead line distance calculating means 42, for example, the position information (latitude information latX, longitude information lonX, altitude information altX) of the pole pole P, the position information (latitude information latA, longitude information lonA) of the young power pole A From the altitude information altA), the distance of the younger-numbered overhead line can be calculated. Further, the overhead line distance calculation means 42 includes position information (latitude information latX, longitude information lonX, altitude information altX) of the pole pole P, position information (latitude information latB, longitude information lonB, altitude information altB) of the old power pole B. ) To calculate the distance of the overhead wire on the younger side.

  Here, when the tension of the overhead wire on the young power pole A side and the tension of the overhead wire on the old power pole B side are unbalanced from the support member 21 of the pole utility pole X, the support member 21 of the pole utility pole X An unbalanced load is applied. This unbalanced load is mainly a horizontal load G. Generally, the number of strips is generally the same between the overhead line erected on the young power pole A side and the older power pole B side with the support member 21 of the pole pole X as a base point. If the type and number of the overhead wires installed on the younger utility pole A side and the older utility pole B side are the same with the support member 21 attached to the utility pole X as the base point, The horizontal load G of the overhead wire erected on the younger power pole A side and the older power pole B side with the support member 21 as the base point is the distance between the younger number side wire and the older number side overhead wire. Is proportional to

  The overhead wire tension calculating means 43 calculates the tension of the younger-numbered overhead line and the tension of the older-numbered overhead line from the distance of the younger-numbered overhead line and the distance of the older-numbered overhead line obtained in step S12 (step S12). S13). As shown in FIG. 10, the overhead wire tension calculating means 43 includes the position information (latitude information latX, longitude information lonX, altitude information altX) of the pole pole P, and the position information (latitude information latA, longitude information) of the young power pole A. lonA, altitude information altA) from the extension direction of the younger-side overhead line and the horizontal load G determined in step S12 according to the magnitude of the distance of the younger-side overhead line, the tension vector FA of the overhead line It can be calculated. The overhead wire tension calculating means 43 is based on the position information of the pole pole P (latitude information latX, longitude information lonX, altitude information altX) and the position information of the old telephone pole B (latitude information latB, longitude information lonB, altitude information altB). An unbalanced stress vector BF having a horizontal load G corresponding to the extension direction of the old number side overhead line and the distance of the old number side overhead line obtained in step S12 can be calculated. In addition, the overhead wire tension calculating means 43 is based on the information in the track design specification information database 32 when the types and the number of the overhead wires installed on the younger utility pole A side and the older utility pole B side are different. It is also possible to add correction to the ratio between the tension of the younger-side overhead wire and the magnitude of the tension of the older-numbered overhead wire.

  The combined tension calculating means 44 calculates the following equation (1) for combining the overhead wire tension vector FA and the tension vector FB obtained in step S13 (step S14).

For example, as shown in FIG. 10, the combined vector F is at a position shifted by an angle θ from the straight line connecting the armored pole power pole X and the old power pole B. For example, θ is 45 degrees, and the angle between the straight line connecting the pole utility pole X and the old power pole B and the straight line connecting the pole pole X and the young pole A is 90 degrees. , The combined vector F has a distance of 50 m between the pole pole P and the old power pole B, and a distance between the pole pole X and the young pole A. 50 m, the load is proportional to the horizontal load G × 50 × 2 ^1/2 (= 70.7 G). When the length T of the support member described above is 3 m and the angle φ formed by the composite vector F and the mounting direction vector V is 90 degrees, the magnitude of the unbalanced stress vector BF is the horizontal load G × The load is proportional to 3 × 2 ^1/2 (= 4.24 G). When the angle φ formed by the composite vector F and the mounting direction vector V is 0 degree, the magnitude of the unbalanced stress vector BF is minimized, so that 6% (= (4.24 G / 70.7 G) × 100 %) The force acting on the support member 21 can be reduced.

  Next, the attachment direction instructing unit 45 calculates the attachment direction vector V of the support member 21 described above based on the orientation information of the orientation measuring device 17. And the attachment direction instruction | indication means 45 processes the output step which performs the output which displays the attachment direction vector V of the supporting member 21 on the display apparatus 14 (step S15). As shown in FIG. 10, it is desirable that the attachment direction instructing means 45 display the combined vector F and the attachment direction vector V of the support member 21 obtained in step S14 on the display device 14 at the same time. Thus, the operator can intuitively recognize the angle difference φ between the combined vector F displayed on the display device 14 and the mounting direction vector V. For this reason, the attachment direction instruction | indication apparatus 10 can guide an operator so that the synthetic | combination vector F and the attachment direction vector V may correspond. The operator can easily match the mounting direction vector V of the support member 21 with the direction of the composite vector F.

  FIG. 11 is an explanatory diagram for explaining the unbalanced stress acting on the base portion of the support member of the dispensed material according to the first embodiment. As shown in FIG. 11, when the mounting direction vector V includes an mounting direction vector V1 having an angle difference φ1 with respect to the composite vector F and an mounting direction vector V2 having an angle difference φ2 with respect to the composite vector F, The vector BF1 and the vector BF2 are expressed by the following expressions (2) and (3).

  Here, the relationship between the angle difference φ1 and the angle difference φ2 shown in FIG. 11 is as shown in Expression (4).

  Assuming that the length of the support member 21 is the same for the attachment direction vector V1 and the attachment direction vector V2, the relationship between the attachment direction vector V1 and the attachment direction vector V2 is as shown in Equation (5).

  Therefore, the relationship between the unbalanced stress vector BF1 and the vector BF2 is expressed by the equation (6).

  Thus, of the angle difference φ1 and the angle difference φ2, the smaller the angle difference, the smaller the unbalanced stress. Therefore, the attachment direction instruction means 45 calculates an angle difference φ between the combined vector F and the attachment direction vector V (step S16). By the angle difference calculation step (step S16) for calculating the angle difference between the combined vector F and the mounting direction vector V of the support member 21, the method for supporting the mounting direction of the squeeze hardware allows the operator to change the mounting direction of the support member 21. The operation of matching the direction of the composite vector F can be supported.

  And the memory | storage device 13 has memorize | stored the tolerance | permissible_range of the angle difference previously, and the attachment direction instruction | indication means 45 performs the angle determination step which judges whether the angle difference (phi) calculated | required by step S16 is in a tolerance | permissible_range ( Step S17). When the angle difference φ obtained in step S16 exceeds the allowable range (step S17, No), the attachment direction instruction means 45 warns the operator (step S18). This warning is realized by the attachment direction instruction means 45 displaying a picture or a character indicating the warning on the display device 14. The warning may be made by a color change, sound, vibration or the like. After the process of step S18, the attachment direction instruction means 45 returns the process to step S16, and calculates the angle difference φ between the combined vector F and the attachment direction vector V.

  When the angle difference φ obtained in step S16 is within the allowable range (step S17, Yes), the attachment direction instruction means 45 issues an attachment instruction to the operator (step S19). This attachment instruction is realized by the attachment direction instruction means 45 displaying a picture or characters indicating the attachment instruction on the display device 14. The attachment instruction may be made by a color change, sound, vibration or the like. By performing the work in accordance with the method of assisting the attachment direction of the dispensed material, the operator can easily determine that the attachment direction vector V of the support member 21 matches the direction of the composite vector F. For this reason, the attachment direction support method of the squeezed material is a work for mounting the sewage product 20 to the pole power pole X so as to reduce the possibility of occurrence of problems such as twisting, deformation, and cracking. Can help.

  As described above, the installation direction support method of the seized item and the installation direction support program of the seized item are the position information of the pole power pole X, the position information of the young power pole A, and the position information of the old power pole B. From the position information acquisition step (step S11) of acquiring the position information, the position information of the pole pole P, the position information of the young pole pole A, and the position information of the old pole pole B, the support member attached to the pole pole P 21, an overhead wire distance calculating step (step S12) for calculating the distance of the overhead wire on the young power pole A side and the distance of the overhead wire on the old power pole B side, and the distance of the overhead wire on the young power pole A side; A tension vector FA and a tension vector obtained by combining the tension vector FA of the overhead wire on the younger power pole A side and the tension vector FB of the older cable side obtained from the distance of the overhead wire on the old power pole B side. Combined vector F combined with FB Calculating a includes synthetic tension calculation steps (step S14), and the output step of outputting the combined vector F and (step S15), and the.

  By working according to the method for assisting the attached direction of the dispensed material, the unbalanced stress generated in the dispensed product 20 is reduced. For this reason, since the worker is supported in the mounting work of attaching the seized material 20 to the pole power pole X, the possibility of problems such as twisting, deformation, and cracking occurring in the sewn material 20 is reduced. Also, by performing the work in accordance with the method of assisting the attachment direction of the withdrawal object, the operator gets off the aerial work vehicle, confirms the state of the cable, and further repeats the fine adjustment of the direction of the support member 21 with the aerial work vehicle. Can be reduced, and the time for attaching the paid-in money 20 can be shortened.

And the attachment direction instruction | indication means 45 displays the attachment direction vector V of the supporting member 21 on the display apparatus 14 (step S25).

  When the lengths of the support members 21 are different, for example, the attachment direction vector V3 shown in FIG. 13 may be larger than the attachment direction vector V1 shown in FIG. The relationship between the attachment direction vector V1 and the attachment direction vector V3 is expressed by the following equation (7).

  Here, the unbalanced stress vector BF3 shown in FIG. 13 is calculated from the mounting direction vector V3, the combined vector F, and the angle difference φ1 by Expression (8).

  If the angle difference φ1 is the same as that of the mounting direction vector V1 shown in FIG. 11, the relationship between the unbalanced stress vector BF1 and the vector BF3 is the relationship shown in Expression (9).

Support for providing information can be provided to workers.

  Then, compared with the allowable load P of the base 21B of the support member 21 stored in the line design specification information database 32 by the storage device 13, the mounting direction instruction means 45 indicates that the unbalanced stress vector BF obtained in step S26 is allowable. An allowable load determination step for determining whether or not it is within the range is executed (step S27). If the unbalanced stress vector BF obtained in step S26 exceeds the allowable load P (No in step S27), the attachment direction instruction means 45 issues a warning to the operator (step S28).

An unbalanced stress vector BF acting on the base 21B of the member 21 is calculated.

  When the unbalanced stress vector BF obtained in step S26 does not exceed the allowable load P and is within the allowable load P and satisfies the following expression (11) (step S27, Yes), the attachment direction indicating means 45 is attached to the operator. An instruction is given (step S29). This attachment instruction is realized by the attachment direction instruction means 45 displaying a picture or characters indicating the attachment instruction on the display device 14. The attachment instruction may be made by a color change, sound, vibration or the like. By performing the work in accordance with the method of assisting the attachment direction of the dispensed material, the operator can easily determine that the attachment direction vector V of the support member 21 matches the direction of the composite vector F.

The correction vector α is parameter information having an azimuth and a size for correcting a composite vector F described later. For example, in a special area sandwiched between mountains, wind blows in a specific direction, and this specific direction and the tension received by the wind act on a composite vector F described later. For this reason, if the composite vector F is corrected with the correction vector α, it is possible to withstand aged stress acting on the dispensed object 20 and to extend the life of the dispensed article 20. In addition, when there is no input of the special area from the input device 15 (step S311, No), the positional information acquisition means 41 advances a process to step S32.

Assuming that φα, the unbalanced stress vector BF can be obtained by the following equation (13) (step S36).

  Then, the storage device 13 compares the allowable load P of the base portion 21B of the support member 21 stored in the line design specification information database 32, and the mounting direction instruction means 45 indicates that the unbalanced stress vector BF obtained in step S36 is allowable. An allowable load determination step for determining whether or not it is within the range is executed (step S37). If the unbalanced stress vector BF obtained in step S36 exceeds the allowable load P (No in step S37), the attachment direction instruction means 45 warns the operator (step S38). This warning is given by the mounting direction instruction means 45 displaying a warning on the display device 14. The warning may be made by a color change, sound, vibration or the like. After the process of step S38, the attachment direction instruction means 45 returns the process to step S36, and acts on the base 21B of the support member 21 from the combined vector F, the attachment direction vector V, the angle difference φ, and the angle difference φα. The unbalanced stress vector BF is calculated.
