Description

[Technical field]

[0001] The present disclosure relates to a technology for supporting the design of privately-operated railway lines, and more particularly to a technology for determining routes and joint positions of privately-operated railway lines. [Background technology]

[0002] Business operators who own power generation facilities may install private lines for power distribution. In doing so, the business operator must consider many items, such as the total length of the private line, the locations of cable joints, and geographical issues along the route where the private line will be installed. Therefore, designing a private line requires a great deal of time and money. In order to reduce the time and cost required for designing such private lines, there is a need for technology to support the design of private lines using map data.

[0003] Regarding technology for utilizing map data in the power business, for example, JP 2022-110629 A (Patent Document 1) discloses an accident point detection support device that includes "a means for acquiring distribution equipment information related to distribution equipment installed on a utility pole (distribution equipment information acquisition task), a means for acquiring map information indicating the installation position of the utility pole and information regarding the surrounding area of ​​the utility pole (map information acquisition task), and a means for identifying, based on the distribution equipment information and the map information, a utility pole on which two or more transformers to which an accident point detection device can be connected are installed, and which has a parking space in which a vehicle equipped with an accident point detection device can enter and ground on which the accident point detection device can be grounded, as a utility pole on which the accident point detection device can be attached (utility pole identification means), and a means for presenting information regarding the utility pole on which the accident point detection device can be attached (information presentation task)" (see [Abstract]).

[0004] [Patent Document 1] JP 2022-110629 A Summary of the Invention [Problem to be solved by the invention]

[0005] According to the technology disclosed in Patent Document 1, it is possible to find utility poles on which a fault point detection device can be attached from a map. However, it is not possible to support the design of new privately-operated lines that are planned to be installed. Therefore, there is a need for a technology that supports the design of new privately-operated lines that are planned to be installed.

[0006] The present disclosure has been made in consideration of the above-described background, and an object of one aspect is to provide a technique for supporting the design of a new privately-operated line that is planned to be installed. [Means for solving the problem]

[0007] According to one embodiment, there is provided a design support device for a private line, the design support device including an input unit that accepts an input of selection conditions for the private line, a storage unit that stores map data, a control unit that executes at least one of selecting a route for the private line on the map data based on the selection conditions and determining one or more joint positions on the route of the private line, and an output unit that outputs the route of the private line and at least one of the one or more joint positions together with the map data.

[0008] In one aspect, the selection conditions include at least one of a road rank condition, a road type condition, a road width condition, and a road distinctiveness condition.

[0009] In one aspect, each of the road rank condition, the road type condition, the road width condition, and the road distinctiveness condition includes a plurality of sub-items linked to an evaluation value. Selecting a route of the private line on the map data includes selecting a route of the private line from the map data based on the weight and the evaluation value.

[0010] In one aspect, the output unit displays one or more road special sections on the route of the private line.

[0013] In one aspect, the control unit calculates the required current based on the specifications of the power plant, calculates the allowable current based on the route of the private line, and determines the size of the cable based on the required current and the allowable current.

[0014] In one aspect, determining the one or more joint locations includes determining the one or more joint locations based on linear information extracted from a route of the selected private line.

[0015] In one aspect, determining one or more joint positions based on linear information extracted from a selected private line route includes decomposing the linear information into one or more straight sections and one or more curved sections, applying a first calculation formula to the one or more straight sections and applying a second calculation formula to the one or more curved sections to calculate tensions and / or lateral pressures generated at each position of the cables that constitute the private line route, and determining one or more joint positions based on the tensions and / or lateral pressures.

[0016] In one aspect, selecting a route for the private line includes selecting a route for a plurality of private lines. The control unit generates estimate data for each of the routes for the plurality of private lines. The output unit outputs the estimate data for each of the routes for the plurality of private lines.

[0017] According to another embodiment, there is provided a design support method for a private line, the design support method comprising: receiving an input of selection conditions for the private line, referring to map data, performing at least one of selecting a route for the private line on the map data based on the selection conditions and determining one or more joint positions of the private line, and outputting at least one of the route of the private line and the one or more joint positions together with the map data.

[0018] According to another embodiment, there is provided a design support program for a private line, the design support program causing a computer to execute at least one of accepting an input of selection conditions for the private line, referring to map data, selecting a route for the private line on the map data based on the selection conditions, and determining one or more joint positions on the route of the private line, and outputting the route of the private line and at least one of the one or more joint positions together with the map data.

Embodiments for Carrying Out the Invention

[0022] Hereinafter, embodiments of the technical idea according to the present disclosure will be described with reference to the drawings. In the following description, the same parts are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed descriptions thereof will not be repeated. Also, each embodiment, each modification example, each software configuration, each hardware configuration, each function, and each process, etc. may be selectively combined as appropriate.

[0023] <A. Screen Examples of the Private Line Design Support Device> First, with reference to FIGS. 1 to 9, the outline and functions of the private line design support device 1000 (see FIG. 10) according to the present embodiment will be described. Each screen shown in FIGS. 1 to 9 is a screen output by the design support device 1000. In a certain aspect, the design support device 1000 may output each screen shown in FIGS. 1 to 9 to a display. In another aspect, the design support device 1000 may output (transmit) each screen shown in FIGS. 1 to 9 to another device via a communication line.

[0024] A private line is a distribution line owned by an electric power company or the like. Private lines connect power plants owned by the company to existing power systems. Private lines are often buried underground. The private line design support device 1000 supports the design of private lines that are to be newly constructed. The design of the private line here includes the selection of the route that the private line will take (hereinafter simply referred to as the "route"), the determination of the size of the cables that make up the private line, and the determination of the joint positions of the private line.

[0025] Designing a private line mainly involves three challenges. The first challenge is route selection. The shorter the route, the lower the construction cost of the private line. Therefore, ideally, the route is the shortest route from the start point to the end point of the private line. However, private lines are usually buried underground under roads. Therefore, operators need to obtain permission from the country, local government, or individual that owns the road in order to construct the private line. In addition, various factors such as the width (width classification) of the road and whether the road crosses a river also affect the construction cost of the private line. Therefore, operators need to select a route taking into account the ease of negotiations for the construction of the private line and other factors.

[0026] The second issue is determining the size of the cables that will make up the privately-operated line. Operators must select the size of the cables based on various conditions, such as the total length of the privately-operated line, the depth from the ground surface to the cable burial position, and the amount of current flowing through the cable.

[0027] The third issue is determining the joint locations of privately-operated lines. Operators must determine the joint locations of cables based on the tension and / or lateral pressure applied to the cables. The tension, etc. applied to each part of the cable varies depending on the route of the privately-operated line (or the degree of bending of the cable, etc.).

[0028] The design support device 1000 provides a business operator (hereinafter, referred to as a "user") with functions for solving the above three problems. By using the design support device 1000, the user can significantly reduce the time required to select a route for a privately-operated line, determine the cable size, and determine the joint positions. Furthermore, by using the design support device 1000, the user can easily obtain estimate data for the privately-operated line that he or she has designed.

[0029] The design support device 1000 has four main functions for supporting the design of privately-operated lines. The first function is a function for selecting a route for the privately-operated line. The second function is a function for determining the size of the privately-operated line (cable). The third function is a function for determining the joint positions of the privately-operated line. The fourth function is a function for generating estimate data for the privately-operated line.

[0030] The design support device 1000 may realize various functions described later with reference to FIGS. 1 to 9 by executing a program on the hardware shown in FIG. 10. In one aspect, the design support device 1000 may be realized as a stand-alone device used by a user. In another aspect, the design support device 1000 may be realized as a server or a cloud service. In this case, the user may use the functions of the design support device 1000 via a browser or the like of his / her own device. For example, the screens shown in FIGS. 1 to 9 are displayed on the browser of the user's device. In addition, the design support device 1000 may accept various inputs from the user via the browser. Furthermore, in another aspect, the functions of the design support device 1000 may be realized by one or more information processing devices. The one or more information processing devices may include a server, a cluster, a cloud environment, and the like. In this case, the design support device 1000 may be said to be a design support system for a private line.

[0031] (a. Screen for route selection of privately-operated lines) FIG. 1 is a diagram showing a first example of a route selection screen for a private line. The screen 100 is a route selection screen related to a first function (route selection function for a private line) provided in the design support device 1000. The screen 100 shows one or more routes selected based on the selection conditions for the private line specified by the user. The user inputs the selection conditions for the private line shown in FIG. 3 to the design support device 1000. The design support device 1000 executes a selection process for one or more routes based on the input selection conditions for the private line, and outputs a result of the selection process. In one aspect, the design support device 1000 may execute only the selection process for the route of the private line based on the selection conditions for the private line specified by the user. In another aspect, the design support device 1000 may execute only the determination process for the joint positions of the route of the private line based on the selection conditions for the private line specified by the user. Furthermore, in another aspect, the design support device 1000 may execute both a process of selecting a route of the private line and a process of determining a joint position of the route of the private line based on the selection conditions of the private line specified by the user. That is, the design support device 1000 may execute at least one of a process of selecting a route of the private line and a process of determining a joint position of the route of the private line based on the selection conditions of the private line specified by the user.

[0032] The screen 100 includes at least a route selection result 140 and a display switching setting 150. The route selection result 140 is a part of the screen 100, and includes one or more routes selected based on a selection condition of a private line specified by a user. In the example of FIG. 1, the route selection result 140 includes routes 110, 120, and 130. More specifically, the route selection result 140 is data in which the routes 110, 120, and 130 are superimposed on the map data 105.

[0033] The design support device 1000 stores map data 1020 (see FIG. 10) in a storage 1003 (see FIG. 10). The route selection result 140 does not need to include all of the map data 1020. The route selection result 140 only needs to display on the screen 100 map data 105 including at least the selected route and its surroundings.

[0034] The display switching setting 150 is a part of the screen 100, and includes a setting for switching between displaying and hiding the selected route. The display switching setting 150 also includes a setting for switching between displaying and hiding the elements on each route in the route selection result 140. The user can switch between displaying and hiding the elements on each route by operating the display switching setting 150. The elements on each route include a joint position and a special part. The joint position is a joint position of a cable constituting a private line. The special part is a place including at least one of a river, a tunnel, a buried cultural property, an agricultural promotion area, an existing buried object, and other special topography. The buried cultural property is, for example, an ancient tomb. If an ancient tomb is excavated during the construction of a private line, the construction may be interrupted. Therefore, it is desirable for the design support device 1000 to select a route that does not include a buried cultural property. The existing buried object is, for example, a gas pipe, a water pipe, a power cable, a communication cable, and the like. If there are existing buried objects on the route of the private line, there is a possibility that the private line cannot be buried to the planned depth. Therefore, it is preferable that the design support device 1000 selects a route that does not include existing buried objects. An example of the setting of the display switching setting 150 is shown in FIG. 2.

[0035] 2 is a diagram showing a second example of a route selection screen for a private line. Screens 200 and 210 show route selection results 140 in which the displayed items have been switched by the display switching setting 150.

[0036] The screen 200 is a screen corresponding to the route selection result 140. The screen 200 includes one route 201 and a display of a special part 202 on the route 201. To explain the screen 200 as an example, in the display switching setting 150, the display of the route 201 is enabled and the display of the other routes is disabled. Also, in the display switching setting 150, the display of the special part 202 is enabled and the display of the joint position 211 is disabled.

[0037] The screen 210 is a screen corresponding to the route selection result 140, and includes a display of one route 201, and a special portion 202 and a joint position 211 on the route 201. To explain using the screen 210 as an example, in the display switching settings 150, the display of the route 201 is enabled, and the display of other routes is disabled. Also, in the display switching settings 150, the display of the special portion 202 and the joint position 211 is enabled.

[0038] As described above, the design support device 1000 for a private line includes an input unit (input IF 1005 (see FIG. 10)) that accepts input of selection conditions for the private line, a memory unit (storage 1003 (see FIG. 10)) that stores map data, a control unit (processor 1001 (see FIG. 10)) that executes at least one of selecting a route for the private line on the map data based on the selection conditions and determining one or more joint positions on the route of the private line, and an output unit (output IF 1006 (see FIG. 10)) that outputs the route of the private line and at least one of the one or more joint positions together with the map data. Thus, the design support device 1000 can automatically select a route based on the map data and the selection conditions, and display the selected route on the map data.

[0039] In another aspect, the output unit (output IF1006) may display one or more special road sections on the route of the private line. The output unit (output IF1006) may also individually switch between displaying and hiding the route, joint positions, and special sections of each private line. The special sections are locations that include at least one of rivers, tunnels, buried cultural properties, agricultural promotion areas, existing buried objects, and other special topography.

[0040] A user can select a route for a private line simply by inputting selection conditions for the private line into the private line design support device 1000. The design support device 1000 can significantly shorten the design period for a private line by automating the route selection work that was previously performed manually by a person in charge while looking at a map.

[0041] The user can also switch between displaying and hiding one or more routes on the route selection result screen 100. Furthermore, the user can switch between displaying and hiding elements (special parts, joint positions) on each route on the route selection result screen 100. This display switching function allows the user to select a route while taking into consideration special parts and joint positions.

[0042] 3 is a diagram showing an example of an input screen for selection conditions of private lines. The input screen for selection conditions is a screen related to a first function. The input screen for selection conditions accepts input of conditions for selecting a route of a private line (selection conditions of a private line). The design support device 1000 selects one or more routes of a private line on the map data 1020 based on the selection conditions of the private line input on the input screen for selection conditions.

[0043] Screens 300A, 300B, 300C, and 300D are all selection condition input screens, and show a switched display state. The selection condition input screen includes major items 310 and a re-categorization table. The display of the re-categorization table changes based on the item selected from the major items 310. For example, when item 311A ​​is selected from the major items 310, re-categorization table 320A is displayed on the screen. Similarly, when item 311B is selected from the major items 310, re-categorization table 320B is displayed on the screen. When item 311C is selected from the major items 310, re-categorization table 320C is displayed on the screen. When item 311D is selected from the major items 310, re-categorization table 320D is displayed on the screen.

[0044] Major items 310 include items 311A, 311B, 311C, and 311D. Item 311A ​​is an item related to "road rank." Road rank indicates the rank of a road set by each management body, such as a national highway, a prefectural road, a city / town / village road, a private road, etc. Item 311B is an item related to "road type." Road type indicates the type of road, such as a normal road, a garden path, stone steps, a sidewalk, etc. Item 311C is an item related to "road width (width classification)." Road width indicates the width of the road. Item 311D is an item related to "road distinctiveness." Road distinctiveness indicates whether the road is a normal road, a special road such as a tunnel or a bridge, and the type of road.

[0045] The input screen for selection conditions also includes weight settings 315 for each item included in the major items 310. The weight settings 315 indicate the importance of each item included in the major items 310 when selecting a route. In the example of FIG. 3, the weights of items 311A, 311B, 311C, and 311D are all 25%. Therefore, the design support device 1000 treats each item equally as a route selection condition. If the weight of item 311A ​​is 70% and the weights of items 311B, 311C, and 311D are each 10%, the importance of item 311A ​​is high. In this case, the design support device 1000 selects a route by giving top priority to satisfying the conditions of item 311A.

[0046] In one aspect, the major items 310 may be configured to be able to add or delete each item. For example, assume that the major items 310 include items 311A, 311C, and 311D, but do not include item 311B. In this case, the design support device 1000 selects a route based on "road rank," "road width," and "road distinctiveness." In other words, the design support device 1000 may exclude "road type" from the route selection criteria.

[0047] The reclassification tables 320A, 320B, 320C, and 320D include sub-items of the items selected from the main item 310 and evaluation values ​​associated with each sub-item. For example, the item 311A ​​(road rank) includes sub-items such as "municipal roads, etc.", "national highways," "prefectural roads," "others," and "NODATA." NODATA indicates a road with no information about the sub-item. The smaller the evaluation value, the higher the priority. In some situations, the larger the evaluation value, the higher the priority. When the item 311A ​​(road rank) is included in the route selection conditions, the design support device 1000 selects a route based on the sub-items of the item 311A ​​and their evaluation values. In the example of FIG. 3, the design support device 1000 preferentially selects "municipal roads, etc." and "prefectural roads" as routes.

[0048] In one aspect, the sub-items in the recategorization table and the evaluation values ​​associated with each sub-item may be configured to be editable. A user may add or delete sub-items, modify evaluation values, and the like as appropriate. In another aspect, the main items 310 may include any items other than the above four types of items. The recategorization table may include any sub-items other than the sub-items shown in FIG. 3.

[0049] The design support device 1000 selects a route for a private line from map data based on each item, weight, and evaluation value included in the selection conditions. For example, assume that a certain point on the map data is a national highway and a bridge. In this case, as an example, the design support device 1000 may evaluate the certain point as "weight of item 311A ​​(road rank) * evaluation value of national highway + weight of item 311D (uniqueness of road) * evaluation value of bridge."

[0050] Screen 300A is a screen in which item 311A ​​(road rank) is selected from main items 310. Screen 300A includes re-categorization table 320A. Re-categorization table 320A includes, as an example, sub-items of road rank, such as "municipal roads, etc.", "national highways," "prefectural roads," "other," and "NODATA." Re-categorization table 320A also includes evaluation values ​​associated with each item.

[0051] Screen 300B is a screen in which item 311B (road type) is selected from main items 310. Screen 300B includes re-categorization table 320B. Re-categorization table 320B includes, as an example, "garden area," "normal area," "stone steps," "sidewalk," and "NODATA," which are sub-items of road type. Re-categorization table 320B also includes an evaluation value associated with each item.

[0052] Screen 300C is a screen in which item 311C (road width) is selected from main items 310. Screen 300C includes re-categorization table 320C. As an example, re-categorization table 320C includes sub-items of road width, such as "less than 3m-5.5m", "less than 3m", "less than 5.5m-13m", "19.5m or more", "less than 13m-19.5m", and "NODATA". Re-categorization table 320C also includes evaluation values ​​associated with each item.

[0053] Screen 300D is a screen in which item 311D (road distinctiveness) is selected from main item 310. Screen 300D includes re-categorization table 320D. Re-categorization table 320D includes, as an example, "normal section," "tunnel," "bridge / elevated road," and "NODATA," which are sub-items of road distinctiveness. Re-categorization table 320D also includes an evaluation value associated with each item.

[0054] As described above, the route selection conditions may include at least one of the following conditions: road rank condition, road type condition, road width condition, and road distinctiveness condition. Furthermore, selecting a private line route on the map data includes setting weights for each of the road rank condition, road type condition, road width condition, and road distinctiveness condition.

[0055] In addition, each of the road rank condition, the road type condition, the road width condition, and the road distinctiveness condition may include a plurality of sub-items linked to an evaluation value. Selecting a route of the private line on the map data includes selecting a route of the private line from the map data based on the weight and the evaluation value.

[0056] The user can set various selection conditions specific to the private line in detail using the selection condition input screens (screens 300A to 300D). This allows the design support device 1000 to automatically select the route of the private line based on the input selection conditions.

[0057] When selecting a route for a privately-operated line, designers must consider various factors such as the total length of the cable, the ease of negotiating the construction of the privately-operated line, construction period, etc. On the selection criteria input screen, users can adjust the weight or evaluation value of each item according to the items they want to prioritize (construction period, cost, etc.).

[0058] 4 is a diagram showing a third example of a private line route selection screen. Screen 400 displays one or more routes selected based on the selection conditions input on the selection condition input screen (screens 300A to 300D). The selected routes include plan A, plan B, and plan C. Taking screen 400 as an example, an example of items that can be switched between displayed and hidden by display switching setting 150 will be described.

[0059] The display switching setting 150 includes a route item 411, a joint item 412, and a special part item 413. In one aspect, each item may be configured with any UI (User Interface) component such as a check box, a radio button, or a pull-down menu.

[0060] The route item 411 is a setting for switching between display and non-display of one or more selected routes. In the example of Fig. 4, the route of plan A and the route of plan B are set to be displayed, and the route of plan C is set to be hidden.

[0061] The joint item 412 is a setting for switching between displaying and hiding the joint positions of each route. In the example of FIG. 4, the joint positions of the route of plan A are set to be displayed. In some situations, the joint item 412 may not include settings for routes for which the joint positions have not been determined. For example, if the design support device 1000 has not performed the process of determining the joint positions of plan B and plan C, the joint item 412 may not include a setting for switching between displaying the joint positions of plan B and plan C.

[0062] The special section item 413 is a setting for switching between displaying and hiding the special sections of each route. In the example of Fig. 4, the intersection point of the route of Plan A with a railroad and the intersection point of the route of Plan B with a river are set to be displayed. In this way, the special section item 413 is configured to be able to switch between displaying and hiding one or more special sections of each route.

[0063] The display contents of the route selection result 140 are switched based on the settings of the display switching setting 150. In the example of Fig. 4, the route selection result 140 displays a route of plan A (route 401) and a route of plan B (route 402). The route selection result 140 also displays a joint position 410 on the route of plan A, and an intersection position 420 between the route of plan A and a railway. The route selection result 140 also displays an intersection position 430 between the route of plan B and a river.

[0064] As described above, the design support device 1000 selects a route of a private line based on the selection conditions. Selecting the route of the private line includes selecting routes of a plurality of private lines. The output unit (output IF 1006) is configured to be capable of individually switching between displaying and not displaying each of the routes of the plurality of private lines, one or more joint positions in each of the routes of the plurality of private lines, and one or more special road parts in each of the routes of the plurality of private lines.

[0065] The user can compare the routes by switching between the displays of various information, which allows the user to compare one or more selected routes while taking into consideration the positions of joints, the presence or absence of special parts, etc.

Screen 500 is a screen related to a second function (a function for determining the size of a private line (cable)). Screen 500 is configured to allow input of information regarding the required current and allowable current of a cable constituting the private line. Based on the conditions input to screen 500, design support device 1000 calculates the required current and allowable current of the cable constituting the private line.

[0067] The screen 500 includes an item 510 for calculating a required current and an item 520 for calculating an allowable current. The item 510 includes items of a transmission voltage, a power plant capacity, and a power factor. It can be said that the item 510 is mainly a specification of a power plant. The item 520 includes a private line distance (total length of cable), an electric frequency, a construction condition, an inner diameter of a pipe, a cable depth, a cable interval, an average specific thermal resistance of soil and a pipe, and a loss rate. It can be said that the item 520 is mainly a specification of a private line.

[0068] All of the individual items included in item 510 and item 520 can be input. Some or all of the items included in item 520 may be automatically input based on the route selection results. In the example of Fig. 5, screen 500 shows the state immediately after item 520 has been input, and the allowable current has not yet been calculated, so the allowable current is 0A.

[0069] FIG. 6 is a diagram showing a second example of a cable size consideration screen. Screen 600 is a screen to which the display of screen 500 has been switched. Design support device 1000 determines (calculates) the required current and allowable current based on items 510 and 520. In the example of FIG. 6, the allowable current is 590 A. Design support device 1000 also determines the cable size based on the required current and allowable current. Furthermore, design support device 1000 displays information 620 of the determined cable size on screen 600. In one aspect, determining the cable size may include selecting a cable type, a coating type, and / or a model number of a product provided by a manufacturer, etc.

The design support device 1000 also calculates the allowable current based on the route of the private line. Furthermore, the design support device 1000 determines the size of the cable based on the required current and the allowable current.

[0071] As described above, the design support device 1000 can automatically determine the size of the cable based on the specifications of the power plant and the specifications of the private line. The user can quickly determine the size of the cable by using the function of determining the size of the private line (cable). In addition, the user can significantly reduce the design man-hours for the private line by combining the function of selecting the route of the private line and the function of determining the size of the private line (cable).

[0072] (c. Screen for determining joint position) FIG. 7 is a diagram showing an example of a group of screens related to joint position determination. Screens 700, 710, and 720 are screens related to the third function (function of determining joint positions of private lines). Screens 700, 710, and 720 show a series of processing results from a selected route to determining a joint position. The design support device 1000 determines a joint position on a route by executing a series of processing described with reference to FIG. 7 and FIG. 8. In a certain aspect, screens 700, 710, and 720 may not be presented to a user. In this case, the design support device 1000 may present only screen 800, which will be described later, to a user.

[0073] The screen 700 displays linear information extracted from the route of the private line. The design support device 1000 extracts linear information that is easy to use for calculation from the selected route. In a certain aspect, the design support device 1000 may extract linear information from the selected route based on receiving a linear information extraction input request from a user. The design support device 1000 may receive the linear information extraction input request from a screen provided by the design support device 1000. As an example, the design support device 1000 may receive the linear information extraction input request on a route selection screen such as the screen 400. The design support device 1000 displays the extracted linear information on the screen 700.

[0074] The screen 710 displays the execution result of the process of dividing the linear information into one or more straight parts and one or more curved parts. The joint position may be determined based on the tension and lateral pressure applied to the cable. The tension and lateral pressure applied to the cable differ depending on the shape (straight or curved) of the cable. Therefore, the design support device 1000 divides the linear information into one or more straight parts and one or more curved parts so that the tension and lateral pressure generated at each part of the cable can be calculated. The design support device 1000 displays the division result on the screen 710. In one aspect, the design support device 1000 may receive an input of a division request from a user on the screen 700. In this case, the design support device 1000 executes the division process based on the reception of the input of the division request, and displays the division result on the screen 710. In another aspect, the design support device 1000 may automatically execute the linear extraction process and the division process in succession.

[0075] The screen 720 shows a combination of each portion of the divided linear information and an equation to be applied to each portion. The equation here is, for example, an equation to calculate the tension and lateral pressure generated for each portion of the cable. The design support device 1000 determines an equation to be applied to each divided portion and displays the combination on the screen 720. In the example of FIG. 7, Equation 1 (first calculation equation) is applied to the straight portion, and Equation 4 (second calculation equation) is applied to the curved portion. The design support device 1000 may have settings registered in advance as to which calculation equation to apply to the straight portion and the curved portion. Equation 1 is, for example, an equation to calculate the tension and lateral pressure of the straight portion of the cable. Equation 4 is, for example, an equation to calculate the tension and lateral pressure of the curved portion of the cable. In a certain aspect, the design support device 1000 may classify the shape of the cable in more detail and apply a different calculation equation to each classified shape. In this case, the design support device 1000 may have three or more calculation equations registered in advance to be applied to each shape. In another aspect, design support device 1000 may automatically and consecutively execute the process of dividing the linear information and the process of determining the equation to be applied to each divided portion. In another aspect, design support device 1000 may separately execute the process of dividing the linear information and the process of determining the equation to be applied to each divided portion based on an input from a user.

[0076] FIG. 8 is a diagram showing an example of a joint position determination screen. The screen 800 is a screen for determining a joint position. The screen 800 includes various threshold value settings 810 and a list 820 of combinations of each part divided from the linear information and an equation applied to each part. The screen 800 also includes a button 805, a study result 840, and information 830 of individual joint positions. The settings 810 indicate various settings that should be observed when designing a private line. The settings 810 include, as an example, a cable tension threshold value, a lateral pressure threshold value, and a transportation limit length. The list 820 includes combinations of each part divided from the linear information and an equation applied to each part. When the design support device 1000 determines a joint position, it inserts information 830 of individual joint positions into the list 820. The button 805 is a button for pasting the information displayed on the screen 720 onto the screen 800 as the list 820. When the button 805 is pressed, the design support device 1000 pastes the information displayed on the screen 720 onto the screen 800 as a list 820. The study result 840 shows information after the joint positions have been determined. The study result 840 may include the number of divisions of the private line and the number of joints.

[0077] In one aspect, screen 800 may be configured to allow input of settings 810. In this case, design support device 1000 accepts each value of settings 810 from a user. In another aspect, design support device 1000 may automatically determine each value of settings 810 from the cable size determined on screen 600. In this case, for example, design support device 1000 may store information on the tension threshold, lateral pressure threshold, and transport limit length for each cable size in storage 1003 in advance. Design support device 1000 may obtain various thresholds and the like from storage 1003 in accordance with the determined cable size, and input the obtained values ​​to settings 810.

[0078] In one aspect, screen 800 may be configured to allow list 820 to be input. In this case, for example, the user may paste information displayed on screen 720 onto screen 800 as list 820. In another aspect, design support device 1000 may paste information displayed on screen 720 onto screen 800 as list 820 by pressing button 805. Furthermore, in another aspect, design support device 1000 may automatically execute the series of processes described with reference to FIG. 7 when displaying screen 800. In this case, design support device 1000 may automatically insert list 820 into screen 800.

[0079] The design support device 1000 calculates the formula applied to each part extracted from the linear information, and calculates the tension and lateral pressure generated at each part. The design support device 1000 provides a joint at a part where the tension and / or lateral pressure exceeds a threshold value. As an example, the joint position may be represented as a blank space in the list 820. Note that the screen of FIG. 8 is merely an example, and the method of representing the joint position is not limited to this. As another example, the joint position may be represented by any method, such as highlighting.

[0080] In a certain aspect, design support device 1000 may execute a joint position determination process as background processing of a route selection process. For example, design support device 1000 may execute up to the joint position determination process based on receiving route selection conditions from a user via screens 300A to 300D. When design support device 1000 selects one or more routes, it may execute a joint position determination process for each route. After the joint position determination process, design support device 1000 may display one or more routes and the joint positions of each route on a route selection screen.

[0081] As shown in FIGS. 7 and 8, determining the one or more joint locations includes determining the one or more joint locations based on linear information extracted from the route of the selected private line.

[0082] Furthermore, determining one or more joint positions based on linear information extracted from the route of the selected private line includes decomposing the linear information into one or more straight sections and one or more curved sections. Also, determining one or more joint positions based on linear information extracted from the route of the selected private line includes calculating tension and / or lateral pressure generated at each position of a cable constituting the route of the private line by applying a first calculation formula (formula 1 on screen 720) to the one or more straight sections and applying a second calculation formula (formula 4 on screen 720) to the one or more curved sections. Furthermore, determining one or more joint positions based on linear information extracted from the route of the selected private line includes determining one or more joint positions based on tension and / or lateral pressure.

[0083] As described above, the design support device 1000 can automatically calculate joint positions that satisfy the cable specifications based on the route selection results. Therefore, the user can obtain both one or more routes and the joint positions of each route simply by inputting route selection conditions on the selection condition input screen.

[0084] (d. Screen for generating quotation data) 9 is a diagram showing an example of an estimate data display screen. The screen 900 is a screen related to the fourth function (a function for generating estimate data for private lines). The screen 900 displays the estimate data for each of one or more selected routes.

[0085] Screen 900 includes cost study result 910 and process study result 920. Cost study result 910 includes information on the cost required to realize each of one or more selected routes. In a certain aspect, the cost of the cable, the cost of each construction work, and the like may be registered in advance in design support device 1000 as cost information. In this case, design support device 1000 may calculate each item of cost study result 910 based on the selected route, the size of the cable, and the cost information.

[0086] The process review result 920 includes information on the man-hours (construction period) required to realize each of the one or more selected routes. In a certain aspect, the man-hours of each construction may be registered in advance as man-hour information in the design support device 1000. In this case, the design support device 1000 may calculate each item of the process review result 920 based on the selected route, the cable size, and the man-hour information.

[0087] As described above, the design support device 1000 may select routes of a plurality of private lines. That is, selecting a route of a private line includes selecting routes of a plurality of private lines. The control unit (processor 1001) generates estimate data for each of the routes of the plurality of private lines. In addition, the output unit (output IF 1006) outputs the estimate data for each of the routes of the plurality of private lines.

[0088] By referring to the screen 900, the user can select a route that suits the purpose from among one or more selected routes based on the cost, man-hours (construction period), and the like.

[0089] In a certain aspect, the design support device 1000 may be configured to be able to cooperate with the first to fourth functions described above. The first to fourth functions are a private line route selection function, a cable size determination function, a joint position determination function, and an estimate data generation function. In this case, the design support device 1000 selects one or more private line routes based on the private line selection conditions input by the user. Next, the design support device 1000 determines the cable size. Next, the design support device 1000 determines the joint positions of each route. Finally, the design support device 1000 creates the estimate data. The design support device 1000 may display the selected route and joint positions, the determined cable size, and the estimate data on one or more screens.

[0090] In other aspects, the design support device 1000 may be configured to be able to execute the first to fourth functions described so far individually. In this case, based on the selection conditions of the private line input from the user, the design support device 1000 can select one or more private line routes. Also, based on the input of a request to determine the cable size, the design support device 1000 determines the cable size. Further, based on the input of a request to determine the joint position, the design support device 1000 determines the joint position of each route. Additionally, based on the input of a request to create estimate data, the design support device 1000 creates estimate data. The design support device 1000 displays information corresponding to the request on the screen. Also, the design support device 1000 may be configured to be able to execute a plurality of processes included in the first to fourth functions individually. Taking the first function as an example, based on the selection conditions of the private line specified by the user, the design support device 1000 can execute at least one of the process of selecting the private line route and the process of determining the joint position of the private line route. For example, based on the selection conditions of the private line specified by the user, the design support device 1000 may execute only the process of selecting the private line route. As another example, based on the selection conditions of the private line specified by the user, the design support device 1000 may execute the process of determining the joint position for the private line route that has already been obtained.
