Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a technique for creating a distribution facility diagram.
[0002]
[Prior art]
In a drawing management system for creating and managing a power distribution equipment diagram for displaying information on electric wires existing between power poles, there are mainly the following two methods.
[0003]
1) Flag system
FIG. 11 shows an example of a power distribution facility diagram of the rising system. As shown in FIG. 11, in the power distribution equipment diagram of the rising system, one line symbol indicating an electric wire is displayed between electric pole symbols indicating electric poles, thereby indicating that electric wires are passed between electric poles. When multiple electric wires are passed between telephone poles, draw a leader line on one line symbol displayed between telephone poles, and declare that multiple electric wires are passed before the lead line as a breakdown of electric wires. Describe.
[0004]
2) Double track display method
In the power distribution equipment diagram of the double-line display method, the same number of line symbols passed between two telephone poles are displayed between pole pole symbols.
[0005]
Further, as an invention related to a power distribution equipment diagram, there is an invention described in Japanese Patent Laid-Open Publication No. Hei 7-114590. According to the present invention, symbols indicating equipment such as a transformer and a switch mounted on a utility pole and their attribute data are automatically arranged near the utility pole symbol in the power distribution facility diagram.
[0006]
[Problems to be solved by the invention]
The above two conventional power distribution equipment diagrams have the following problems, respectively.
[0007]
1) Flag system
1. At a glance, the wiring status of the wires could not be grasped, and it was necessary to read the breakdown of the wires displayed at the end of the lead wire.
[0008]
2. In places where the equipment is congested, the power distribution equipment diagram was difficult to see due to the rising lines.
3. Since only one line symbol can be displayed between utility poles, the power distribution equipment diagram cannot be displayed so that the color of the line symbol is changed according to the type of electric wire.
[0009]
2) Multiple display method
1. Since each line symbol has coordinates indicating a start point and an end point, when registering a line symbol, the user specifies two telephone pole symbols on which the line symbol is to be displayed, and then specifies two of the pole symbols. The procedure was complicated because it was necessary to indicate the end points, that is, the positions of the start point and the end point on the distribution equipment diagram. In particular, when the number of line symbols to be displayed is large, the procedure is very complicated.
[0010]
2. When the line symbol supported by the moved telephone pole is moved along with the movement of the telephone pole symbol, a considerable amount of processing time is required because the amount of calculation for calculating the coordinates of the start point and the end point of the moved line symbol is large. I needed it.
[0011]
Hereinafter, a process of calculating the coordinates of the starting point and the ending point of the moved line symbol when the line symbol is moved in accordance with the movement of the utility pole symbol in the conventional double-line display method will be described in detail with reference to FIGS. explain.
[0012]
First, the coordinates used in the description of FIG. 13 will be described with reference to FIG. In FIG. 12, a utility pole symbol that does not move is shown as a reference utility pole, and a utility pole symbol to be moved is shown as a moving utility pole. In the following description, as shown in FIG. 12, a reference telephone pole is assumed as an origin of a rectangular coordinate system and a polar coordinate system, and the following symbols are used.
[0013]
(X1, Y1): coordinates of moving pole before moving in rectangular coordinate system
(R1, θ1): coordinates of the moving pole before moving in the polar coordinate system
(X1 ', Y1'): coordinates of moving pole after moving in rectangular coordinate system
(R1 ′, θ1 ′): coordinates of the moving pole after moving in the polar coordinate system
(X2, Y2): coordinates in the rectangular coordinate system of the terminal on the moving pole side before the movement of the line symbol supported by the reference pole and the moving pole
(R2, θ2): coordinates in the polar coordinate system of the terminal on the moving power pole side before the movement of the line symbol supported by the reference power pole and the moving power pole
(X2 ', Y2'): coordinates in the rectangular coordinate system of the terminal on the moving power pole side after the movement of the line symbol supported by the reference power pole and the moving power pole
(R2 ′, θ2 ′): Coordinates in the polar coordinate system at the end of the moving power pole side after the movement of the line symbol supported by the reference power pole and the moving power pole
Hereinafter, a process of calculating the coordinates of the terminal of the moved line symbol when the line symbol is moved in accordance with the movement to the utility pole symbol will be described with reference to FIG.
[0014]
When the process of calculating the coordinates of the end of the line symbol supported by the moving electric pole on the moving electric pole side is started, first, the coordinates (X1, Y1) of the moving electric pole in the rectangular coordinate system before the movement and the coordinates before the movement of the line symbol are moved. The coordinates (r1, θ1) and the coordinates (r2, θ2) are obtained by converting the coordinates (X2, Y2) of the rectangular coordinate system at the end on the side of the moving power pole into the coordinates of the polar coordinate system (S1). Note that a calculation method for converting coordinates in a rectangular coordinate system into coordinates in a polar coordinate system is widely known, and thus description thereof is omitted.
[0015]
Then, the coordinates (r1 ′, θ1 ′) are obtained by transforming the coordinates (X1 ′, Y1 ′) of the moving electric pole after the movement into the coordinates of the polar coordinate system (S3). Further, the coordinates (r2 ′, θ2 ′) in the polar coordinate system at the terminal on the moving pole side after the movement of the line symbol are obtained by the following equation (S4).
[0016]
r2 ′ = n × r2
θ2 ′ = θ2 + θ1′−θ1
Here, n = r1 '/ r1, and indicates the change count of the distance between the basic power pole and the moving power pole after moving.
[0017]
Further, the coordinates (X2 ', Y2') are obtained by converting the obtained coordinates (r2 ', θ2') in the polar coordinate system to the rectangular coordinate system (ST4). The coordinates (X2 ′, Y2 ′) in the rectangular coordinate system at the end of the line symbol on the moving utility pole side are obtained by the procedures of ST1 to ST4.
[0018]
Subsequently, in the same manner as in ST1 to ST4, the coordinates of the end of the line symbol on the basic utility pole side in the orthogonal coordinate system are obtained (ST5). Finally, a power distribution facility diagram is created based on the calculated coordinates in the orthogonal coordinate system (ST6), and the process ends. Note that, in this description, only one line symbol has been described. However, when a plurality of line symbols are supported by a moving power pole, the above processing is repeated by the number of line symbols.
[0019]
As described above, the movement of the line symbol accompanying the movement of the telephone pole symbol in the related art required a complicated calculation process.
Further, the above-mentioned Japanese Patent Application Laid-Open No. Hei 7-114590 only discloses that a symbol indicating equipment installed on a power pole is automatically arranged in the vicinity of a power pole symbol in a power distribution equipment diagram. Does not provide.
[0020]
In view of the above problems, it is a first object of the present invention to simplify line symbol input processing when creating a wiring diagram of a double-line display method. Further, a second object of the present invention is to make it possible to quickly calculate the coordinates of the moved line symbol in the movement of the line symbol accompanying the movement of the utility pole symbol.
[0021]
[Means for Solving the Problems]
According to one embodiment of the present invention, there is provided a computer program for causing a computer to execute a control for creating a power distribution facility diagram, wherein a line symbol displayed between two pole symbols and the pole are displayed. An offset value that is information indicating a positional relationship with a symbol is acquired, and the power distribution equipment of the line symbol is obtained based on the power pole position information indicating the position of the two power pole symbols on the power distribution equipment diagram and the offset value. Generating electric wire position information indicating a position on the diagram, based on the generated electric wire position information, displaying the line symbol on the power distribution equipment diagram, and causing the computer to perform control including: Features.
[0022]
Electric wire position information of the line symbol is generated based on an offset value indicating a positional relationship between the line symbol displayed between the two electric pole symbols and the electric pole symbol and electric wire position information of the electric pole symbol constituting the span. By doing so, it is not necessary for the user to specify the position of the line symbol.
[0023]
In the computer program, when the utility pole symbol constituting the span is moved, the electric wire of the moved line symbol is moved based on the offset value and the utility pole position information of the moved utility pole symbol. The computer may perform control further including generating position information.
[0024]
Also in the process of moving the line symbol accompanying the movement of the utility pole symbol, the wire position information of the moved line symbol can be generated based on the offset value and the wire position information of the center of the utility pole symbol, so that it is Thus, it is possible to quickly perform a process associated with the movement of the utility pole symbol.
[0025]
Still further, in the computer program, generating span information including utility pole symbol identification information for identifying the utility pole symbol constituting the span and line symbol identification information for identifying the line symbol displayed in the span. In addition, the computer may perform control further including managing line symbols displayed in the span using the span information. This makes it possible to add, delete, or change line symbols, for example, not for each line symbol but for each span.
[0026]
Here, the offset value may correspond to the type of the electric wire indicated by the line symbol, or may correspond to the number of lines of the line symbol displayed in the span. This makes it possible to display a line symbol at a position relatively determined with respect to the utility pole symbol in accordance with the type of electric wire and the number of lines, thereby making it possible to create an easy-to-understand power distribution equipment diagram.
[0027]
The offset value may indicate a distance between a first reference line connecting the centers of the two utility pole symbols and the line symbol. The distance between a second reference line perpendicular to the reference line and the line symbol may be indicated. Using such offset values, it is possible to express the positional relationship between line symbols and utility pole symbols.
[0028]
In addition, the above problem can also be solved by causing a computer to read and execute the computer program from a computer-readable recording medium that stores the computer program.
[0029]
In addition, by causing the computer to execute the computer program, the same operation and effect as those obtained by executing the computer program by the computer can be obtained by the power distribution equipment diagram creation method including the procedure performed by the computer. Therefore, the above problem can be solved.
[0030]
The same operation and effect as those of the above-described power distribution facility diagram creation method can be obtained by the power distribution facility diagram creation device that performs the same processing as the procedure performed in the power distribution facility diagram creation method, so that the above problem can be solved. is there.
[0031]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the same reference numerals are given to the same devices and the like, and description thereof will be omitted.
[0032]
FIG. 1 shows a configuration of a power distribution equipment diagram creating apparatus 10 according to the present invention. The power distribution equipment diagram creation apparatus 10 creates a power distribution equipment diagram showing the equipment status of devices related to power distribution, for example, installation of telephone poles, wiring of electric wires, and the like. As shown in FIG. 1, the power distribution equipment diagram creating apparatus 10 includes a record search unit 11, a span record creating / updating unit 12, a drawing control unit 13, a drawing coordinate record creating / updating unit 14, a span record storing unit 15, A drawing coordinate record storage unit 16, a segment definition record storage unit 17, and an input / output device 18 are provided.
[0033]
The record search unit 11 receives a telephone pole symbol designation from a user or another device via the input / output device 18, and stores a span record or a drawing coordinate record relating to the designated utility pole symbol in a span record storage unit. 15 and the drawing coordinate storage unit 16.
[0034]
The span record is information on the span. A line symbol is displayed based on the span record. The span is between utility pole symbols. The drawing coordinate record is information on coordinates indicating positions on the power distribution equipment diagram at both ends of the line symbol displayed in the span. The structures of the span record and the drawing coordinate record will be described later.
[0035]
As a result of the search for the span record by the record search unit 11, if the span record relating to the designated utility pole symbol is not stored in the span record storage unit 15, the span record creating / updating unit 12 transmits the span record. A record is created, and the span record is registered in the span record storage unit 15. When the span record relating to the designated utility pole symbol is stored in the span record storage unit 15, the span record creating / updating unit 12 outputs the span record based on the information input through the input / output device 18. Update inter-record.
[0036]
The drawing control unit 13 determines the coordinates of the start point and the end point of the line symbol based on the span record and the segment definition record, and controls the input / output device 18 to output the line symbol to the power distribution equipment diagram. The segment definition record includes information on a display method of the line symbol corresponding to the type of the electric wire indicated by the line symbol and information on a positional relationship between the line symbol and the utility pole symbol. The drawing coordinate record creating / updating unit 14 creates or updates a drawing coordinate record.
[0037]
The span record storage unit 15, the drawing coordinate record storage unit 16, and the segment definition record storage unit 17 store a span record, a drawing coordinate record, and a segment definition record, respectively. The structure of the segment definition record will be described later in detail.
[0038]
The input / output device 18 inputs an instruction from a user or another device to the power distribution equipment diagram creating device 10, and outputs an inquiry from the power distribution equipment diagram creating device 10 to a user or the like.
[0039]
Next, the structures of various records will be described with reference to FIGS. First, the structure of the span record will be described with reference to FIG.
As shown in FIG. 2, the span record includes a utility pole ID for identifying a utility pole symbol constituting a span related to the span record and an electric wire ID for identifying a line symbol passed between the spans. Since the span is composed of two utility pole symbols, the span record includes two utility pole IDs as shown in FIG. Although not shown in FIG. 2, the span record may further include a span length indicating the span length and other information as special items. Special notes are displayed on the distribution equipment diagram.
[0040]
Next, the structures of the drawing coordinate record and the segment definition record will be described with reference to FIG. The drawing coordinate record includes an electric wire ID for identifying a line symbol related to the drawing coordinate record, a segment number corresponding to the type of electric wire indicated by the line symbol, and coordinates of a start point and an end point of the line symbol. Note that the coordinates of the start point and the end point of the line symbol are determined by the drawing control unit 13.
[0041]
The segment definition record is stored in advance in the segment definition record storage unit 17 of the power distribution equipment diagram creating apparatus 10 according to the line type of the line symbol, and is updated as needed when the power distribution equipment diagram creating apparatus 10 is upgraded.
[0042]
The segment definition record includes a segment number, a primitive, an offset value on the X coordinate side, and an offset value on the Y coordinate side. The primitive (drawing element) indicates a line type, a line thickness, a color, and the like when displaying a line symbol. A segment definition record may include a plurality of primitives.
[0043]
The offset value indicates a positional relationship between the line symbol and the utility pole symbol. The offset value includes an X offset value and a Y offset value. The detailed description of the offset value will be described later with reference to FIG.
[0044]
As described above, by providing the segment definition record, the power distribution equipment diagram creating apparatus 10 can control the relative relationship between the displayed line symbol and the utility pole symbol in accordance with the type of the electric wire indicated by the line symbol based on the segment definition record. It is possible to change the position, line type, line thickness, line color, and the like.
[0045]
More specifically, for example, a primitive is set so that a line symbol indicating a high-voltage line is displayed using a thick solid line, and the first high-voltage line is displayed near the center of the utility pole symbol. It is also possible to set an offset value in Also, for example, a primitive is set so that a line symbol indicating an imaginary ground line is displayed using a thin dashed line, and furthermore, the imaginary ground line is displayed on the outermost side as viewed from the center of the electric wire symbol. It is also possible to set an offset value in.
[0046]
This makes it possible to create a power distribution equipment diagram that is easy for the viewer to understand.
Next, coordinate notations of various symbols will be described with reference to FIG. The position where the utility pole symbol is displayed is indicated by the coordinates of the center of a circle (or another figure) indicating the utility pole symbol. The coordinates of the center and the radius of the circle indicating the utility pole symbol are based on designation from a user or another device.
[0047]
The position of the line symbol is indicated by the coordinates of the start point and the coordinates of the end point. The coordinates of the start point and the end point are determined by the coordinates of the center of the two utility pole symbols constituting the span where the line symbol is displayed, and the X offset value and the Y offset value included in the segment definition record.
[0048]
In FIG. 4, two utility pole symbols constituting the span are indicated by circles. Here, the power pole symbol on the left side of the drawing is the power pole on the start point side of the line symbol, and the power pole symbol on the right side is the power pole on the end point side of the line symbol. A line connecting the centers of the two utility pole symbols is defined as an X reference line, and a line passing through the center of the utility pole symbol and perpendicular to the X reference line is defined as a Y reference line. There is one Y reference line on each of the start point side and the end point side. A line symbol is a line segment parallel to the X reference line.
[0049]
The X offset value indicates the distance between the start point of the line symbol and the Y reference line on the start point side, or the distance between the end point of the line symbol and the Y reference line on the end point side. Therefore, the line symbol is a line segment shorter by 2X than the reference line.
[0050]
The Y offset value indicates the distance between the start or end point of the line symbol and the X reference line, in other words, the distance between the line symbol and the X reference line.
As described above, the X offset value and the Y offset value are information indicating the positional relationship between the coordinates of the electric poles forming the span and the start point and end point of the line symbol displayed on the span.
[0051]
According to the power distribution equipment diagram creating apparatus 10, by using these X offset value and Y offset value, the coordinates of the utility pole symbol constituting the span, the type of electric wire indicated by the line symbol, and the number of lines of the same type of electric wire When the information indicating the above is specified, the coordinates of the start point and the end point of the line symbol are determined. Therefore, since it is not necessary for the user or the like to specify the coordinates of the start point and the end point of the line symbol, the procedure for inputting information can be simplified.
[0052]
Next, a process of displaying a line symbol in the power distribution equipment diagram creating apparatus 10 according to the present invention will be described with reference to FIG.
When drawing a line symbol, the user selects a utility pole symbol that constitutes a span, and includes the type of wire indicated by the line symbol desired to be displayed in the span, and further includes the same type of wire between the spans. In this case, the user inputs information indicating the number of lines of the same type of electric wire, and then instructs a drawing process. Since the span is composed of two utility pole symbols, it is necessary in principle to designate two utility pole symbols. When a power pole symbol is designated, if a GUI (Graphic User Interface) is employed in the power distribution equipment diagram creating apparatus 10, for example, the user may select a power pole symbol constituting a span with a pointer. .
[0053]
When a line symbol drawing process is instructed (S1), a utility pole ID for identifying a utility pole symbol selected by a user or the like is input from the input / output device 18 to the span record selection unit 11 (S2). The record search unit 11 searches the span record storage unit 15 using the telephone pole IDs as search keys (S3). When the span record corresponding to the input telephone pole ID is obtained as a result of the search (S4: Yes), the process proceeds to S6.
[0054]
Since a span record is created when a span symbol is displayed for the first time, the fact that a span record has already been created means that one span symbol is already displayed. This means that it exists. Therefore, the subsequent processing is for adding a line symbol to be displayed in the span.
[0055]
When the corresponding span record is not acquired (S4: No), the span record creating / creating unit 12 creates a span record including the input telephone pole ID (S5), and proceeds to S6.
[0056]
In S6, the span record creating / updating unit 12 sets the line symbol based on the type of the electric wire input by the user and the information indicating the number of the line of the same type of electric wire (if input). Is determined, and the wire ID is added to the span record.
[0057]
The electric wire ID may be determined so that information indicating the type of the electric wire indicated by the line symbol, the span in which the line symbol is displayed, and the number of the line of the same type of electric wire in the span can be understood. For example, a number is assigned in advance according to the type of electric wire, such as "1" for a high-voltage line and "2" for a low-voltage line. When the type of the electric wire indicated by the line symbol is “high-voltage line”, the power pole IDs of the power poles forming the span are “# 1” and “# 2”, and the first high-voltage line in the span, the order is as follows. May be determined as "1_ # 1- # 2-01".
[0058]
Subsequently, the drawing control unit 13 determines the segment number based on the type of the electric wire indicated by the line symbol and information indicating the number of the electric wire of the same type in the span. Further, the drawing control unit 13 acquires the segment definition record corresponding to the segment number from the segment definition record storage unit 17 and converts the segment definition record into the center coordinates of the two utility pole symbols and the X offset value and the Y offset value included in the segment definition record. Based on this, the coordinates of the start point and the end point of the line symbol are calculated (S7). Since the calculation method is self-evident, a description thereof will be omitted.
[0059]
Further, the drawing control unit 13 controls the input / output device 18 based on the coordinates of the start point and the end point of the line symbol and the primitive included in the segment definition record so as to display the line symbol on the power distribution equipment diagram. If a special note is included in the span record, the drawing control unit 13 displays the special note below the line symbol (S8).
[0060]
Finally, when an instruction is given from the user or the like, the drawing coordinate record creating / updating unit 13 creates a drawing coordinate record for the displayed line symbol (S9), and ends the processing. When a drawing coordinate record is created, the record can be used to cause the power distribution equipment diagram creating apparatus 10 to create a power distribution equipment drawing after this processing.
[0061]
If it is desired to delete the line symbol displayed in the span, the following processing is performed. First, the record search unit 11 acquires span records from the span record storage unit 15 using the wire ID of the line symbol to be deleted. The span record creating / updating unit 12 deletes the wire ID from the span record, and the drawing coordinate record creating / updating unit 14 deletes the drawing coordinate record having the wire ID from the drawing coordinate record storage unit 16. .
[0062]
FIG. 6 shows a display example of line symbols in a distribution facility diagram. In FIG. 6, circles indicated by dotted lines indicate utility pole symbols constituting the spans, and various line segments displayed between utility poles indicate line symbols. The number given to each line symbol is a segment number. In FIG. 6, the segment numbers of the first high-voltage line, the second high-voltage line, the overhead branch line, the first low-voltage line, the third high-voltage line, and the overhead ground line are 1, 2, and 3, respectively. , 4, 5 and 6.
[0063]
As shown in FIG. 6, the distribution equipment diagram creating apparatus 10 can create a distribution equipment diagram of a double-track display system. Further, a segment number is determined for the line symbol according to the type of the electric wire indicated by the line symbol, and a segment definition record corresponding to the segment number is given in advance. The segment definition record includes an offset value indicating at which position of the span the line symbol should be displayed. Therefore, in accordance with the type of electric wire, it is determined at which position of the span the line symbol is displayed.
[0064]
Next, a process of calculating the coordinates of the starting point and the ending point of the moved line symbol when the line symbol is moved according to the movement to the utility pole symbol will be described with reference to FIGS.
[0065]
First, the coordinates used in the following description will be described with reference to FIG. In FIG. 7, the utility pole symbol that does not move is shown as a reference utility pole, and the utility pole symbol to be moved is shown as a moving utility pole. In the following description, a line symbol is displayed between the reference power pole and the transfer pole, it is assumed that the reference power pole is a power pole on the starting point side of the line symbol, and that the moving power pole is a power pole on the end point side. In the following description, as shown in FIG. 7, a reference telephone pole is assumed as an origin of a rectangular coordinate system, and the following symbols are used.
[0066]
(X1, Y1): coordinates of telephone pole before moving
(X1 ', Y1'): coordinates of the pole after moving
(X2, Y2): coordinates of the end point before the movement of the line symbol
(X2 ', Y2'): coordinates of the end point after the movement of the line symbol
(X3, Y3): coordinates of the starting point before the movement of the line symbol
(X3 ', Y3'): coordinates of the starting point after the movement of the line symbol
Hereinafter, a process when the line symbol is moved with the movement to the utility pole symbol will be described with reference to FIG.
[0067]
When moving the utility pole symbol, the user or another device selects the moving utility pole to be moved, specifies the coordinates after the movement, and instructs the drawing process. When a power pole symbol is specified, if a GUI (Graphic User Interface) is employed in the power distribution equipment diagram creating apparatus 10, for example, the user may move the moving power pole with a pointer.
[0068]
When the process of moving the utility pole symbol is instructed (S11), the utility pole ID of the mobile utility pole and the coordinates (X1 ', Y1') after the movement are input from the input / output device 18 to the record search unit 11 (S12). The record search unit 11 acquires the span record including the utility pole ID from the span record storage unit 15 (S13).
[0069]
Subsequently, the coordinates of the start point and the end point of the line symbol related to the wire ID included in the span record searched as described below are recalculated. When a plurality of span records are searched in S13, that is, when there are two or more spans constituted by the moving power poles, the following steps S14 to S17 are performed for all span records. . When a plurality of wire IDs are included in the span record, the processes of S15 and S16 are performed for all wire IDs.
[0070]
Subsequently, the drawing control unit 13 determines a segment number based on the wire ID included in the span record, acquires a segment definition record corresponding to the segment number from the segment definition record storage unit 17, and obtains the The coordinates of the end point of the line symbol are calculated based on the center coordinates and the X offset value and the Y offset value included in the segment definition record (S15). Similarly, the drawing control unit 13 calculates the coordinates of the starting point of the line symbol based on the center coordinates of the reference telephone pole, the X offset value, and the Y offset value (S16). Note that the calculation method is the same as that of FIG. 5 and is self-evident, so that the description thereof is omitted.
[0071]
After performing S15 and S16 for all wire IDs included in all span records searched in S13, the drawing control unit 13 determines the coordinates of the start and end points of the line symbol and the primitives included in the segment definition record. Then, the input / output device 18 is controlled so that the line symbol is displayed on the distribution equipment diagram (S17).
[0072]
Finally, when instructed by the user or the like, the drawing coordinate record creating / updating unit 13 stores the drawing coordinate record including the wire ID of the line symbol whose drawing coordinates have been recalculated with the movement of the telephone pole, in the drawing coordinate record. The coordinates of the start point and the end point acquired from the unit 16 and included in the acquired drawing coordinate record are updated (S18), and the process ends.
[0073]
As described above, according to the power distribution equipment diagram creating apparatus 10, the coordinates of both ends of the line symbol are indicated using the relative coordinates with respect to the center coordinates of the two utility pole symbols constituting the span. Therefore, when the line symbol is moved in accordance with the movement to the utility pole symbol, it is not necessary to convert coordinates of both ends of the moved line symbol from coordinates in the orthogonal coordinate system to coordinates in the polar coordinate system. Therefore, according to the present invention, it is possible to calculate the coordinates of both ends of the moved line symbol by a simpler procedure than in the past. As a result, it is possible to reduce the time required for the processing associated with the movement of the utility pole symbol.
[0074]
The distribution facility diagram creation device 10 described above can be configured using a computer. Hereinafter, the configuration of the computer will be described with reference to FIG.
[0075]
As shown in FIG. 9, the computer 20 includes a CPU 21, a memory 22, an input device 23, an output device 24, an external storage device 25, a medium drive device 26, and a network connection device 27, which are connected to each other by a bus 28. I have.
[0076]
