  Hereinafter, a design support apparatus 1 according to an embodiment of the present invention will be described with reference to the drawings.

  The design support device 1 supports design for wiring a cable in a virtual three-dimensional space (hereinafter referred to as “three-dimensional virtual space”) displayed by a three-dimensional CAD (Computer-Aided Design) function of the device itself. It is a device to perform. As shown in FIG. 1, the design support apparatus 1 includes a calculation unit 10, a storage unit 20, an input unit 30, a display unit 40, an interface 50, and a bus line BL.

  At the time of wiring design, the arithmetic unit 10 displays a design screen representing a three-dimensional virtual space, and also displays a feature value representing the characteristics of a cable actually wired in the past (cable that has been actually wired). In addition, the arithmetic unit 10 verifies whether the designed wiring is actually applicable to an actual three-dimensional space, that is, a three-dimensional real space, using the feature amount. The arithmetic unit 10 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), and a RAM (Random Access Memory) (not shown).

  The CPU executes a program stored in the ROM (for example, processing of flowcharts shown in FIGS. 6 to 8 described later).

  In addition, the calculation unit 10 causes the CPU to execute a program stored in the ROM so that the wiring design support unit 11, the wiring verification unit 12, the verification result display unit 13, the design information selection unit 14, the feature amount The functions of the acquisition unit 15, the identification information reception unit 16, and the feature amount display control unit 17 are realized.

  The wiring design support unit 11 realizes a three-dimensional CAD function. The wiring design support unit 11 displays the three-dimensional virtual space on the display unit 40, and supports the design in which the cable is wired on the arrangement surface on which the cable is arranged in the three-dimensional virtual space. Specifically, the wiring design support unit 11 includes coordinates on the outer periphery of the cable wired in the three-dimensional virtual space, coordinates of the fixed position of the cable designed for wiring, and the three-dimensional virtual space where the cable is designed for wiring. The coordinates on the wall surface are acquired via the input unit 30. These three coordinates are hereinafter referred to as a “design coordinate group”.

  In addition, the wiring design support unit 11 at the start of the wiring design, the cable name that identifies the cable used for the design, the shape of the three-dimensional virtual space (for example, only a straight line or with bending), and the cross section of the three-dimensional virtual space Information having a shape (for example, a circle or a rectangle), that is, cable information in the wiring design data is acquired via the input unit 30. The cable information in the accepted wiring design data is stored in the design information storage unit 22 in association with the wiring design data (design coordinate group).

  The wiring verification unit 12 determines whether or not the wiring design data received by the wiring design support unit 11 can actually be applied in the actual three-dimensional space, that is, in the three-dimensional real space. Verification is performed by using a feature value representing the characteristics of the cable (the actual wired cable).

  Specifically, the wiring verification unit 12 determines a wiring design margin (virtual margin), an isolation distance (virtual isolation distance), a bending radius (virtual bending radius) from the wiring design data (design coordinate group). And fixed intervals (virtual fixed intervals) are obtained, and whether or not they satisfy the feature quantities (specifically, the margin condition, the separation distance condition, the bending radius condition, and the fixed interval condition). Verify that. Hereinafter, these four feature amounts are referred to as wiring conditions.

  The margin is the ratio between the total length of the cable in the design and the total length of the cable when the cable is temporarily routed so as to have the shortest length in the three-dimensional virtual space. Is the ratio of the total length of the cable to the total length of the cable when the cable is temporarily wired so as to have the shortest length in the actually wired three-dimensional real space.

  The separation distance is the distance at a plurality of locations between the cable in the design and the wall surface constituting the three-dimensional virtual space, and the separation distance condition is the cable in the past actual wiring and the actually wired three-dimensional real space. Is the shortest distance among the distances at a plurality of locations with the wall surface constituting the.

  The bending radius is the bending radius of the cable at the place where the cable is bent in the design, and the bending radius condition is the shortest radius among the bending radii of the cable in the past actual wiring.

  The fixed interval is the interval at which the cable is fixed to the wall surface constituting the three-dimensional virtual space in the design, and the fixed interval condition is the cable fixed to the wall surface constituting the three-dimensional real space in the past actual wiring. This is the longest interval among the intervals.

  The verification result display unit 13 displays the result verified by the wiring verification unit 12 on the display unit 40.

  The design information selection unit 14 receives an input from the designer via the input unit 30 of a design number (see FIG. 4) that is information for specifying a design coordinate group to be verified by the wiring verification unit 12.

  The feature amount acquisition unit 15 uses a coordinate group that specifies a cable arrangement plane in a three-dimensional real space and a coordinate group that specifies the position of the cable wired on the arrangement plane, measured using an external measurement device. Through the interface 50. Specifically, the feature amount acquisition unit 15 has coordinates at a plurality of locations on the outer periphery of the cable actually wired in the three-dimensional real space, coordinates where the actually wired cable is fixed, and the cable actually wired. The coordinates at a plurality of locations on the wall surface of the three-dimensional real space are acquired. These three coordinates are referred to as a measurement coordinate group.

  In addition, the feature amount acquisition unit 15 performs cable routing in the actual wiring from the coordinates on the outer circumference of the actually wired cable and the coordinates on the wall surface of the three-dimensional real space where the cable is actually wired in the measurement coordinate group. Find the path, margin condition, isolation condition, and bending radius condition. In addition, the feature amount acquisition unit 15 obtains the fixed interval condition using the coordinates to which the actually wired cable is fixed in the measurement coordinate group. In this way, the feature amount acquisition unit 15 obtains the wiring condition (feature amount).

  Here, with reference to FIG. 2, the feature amount acquisition unit 15 uses the measurement coordinate group to determine a cable wiring route and a wiring condition (margin condition, isolation distance condition, bending radius condition, and fixed interval condition). To explain.

  FIG. 2A shows a schematic diagram of an actual wiring cable C and an arrangement surface in the three-dimensional real space where the cable C is actually wired, and the cable is set to have the shortest length on the arrangement surface where the cable is actually wired. FIG. 2B shows a schematic diagram of the cable when C is temporarily wired. In FIG. 2, coordinate groups acquired from an external measuring device, that is, measurement coordinate groups are indicated by black circles.

  The measurement coordinate group is obtained by measuring the coordinates extracted from the result of measuring the wall S and the cable C of the three-dimensional real space as a three-dimensional shape with an X-ray CT (Computerized Tomography) scanning device after the cable is actually wired in the three-dimensional real space. Use it. In addition, a thin tube may be placed along the wall surface S and the cable C in the three-dimensional real space, hot water or cold water may be poured into the tube, and coordinates extracted from the result of measurement with an infrared camera may be used. In this embodiment, the measurement coordinate group acquired from the external measurement device includes the coordinate group of the wall surface S, the coordinate group on the outer periphery of the cable C, the coordinate group of the midpoint of the cable C, and the coordinates of the fixed position of the cable. Each coordinate attribute such as a group is associated. Therefore, the feature quantity acquisition unit 15 can accurately obtain the wiring route and the wiring condition of the cable using the acquired measurement coordinate group.

  When obtaining the cable arrangement route, the feature amount acquisition unit 15 obtains the shape (arrangement surface) of the wall surface S from the coordinates of the wall surface S of the three-dimensional real space where the cable C is actually wired. The feature amount acquisition unit 15 obtains the shape of the cable C from the coordinates on the outer periphery of the cable C. The feature amount acquisition unit 15 obtains the arrangement path of the cable C (see FIG. 3) by synthesizing (superimposing) the obtained shape of the wall surface S and the shape of the cable C. Since the wiring route of this cable can be displayed on the display unit 40 at the time of wiring design, the designer can perform the wiring design with reference to the displayed wiring route.

  Further, when obtaining the margin condition, the feature amount acquisition unit 15 first, as shown in FIG. 2B, the cable when the cable C is temporarily wired to the shortest length on the actually wired arrangement surface. Find the total length L ′ of C. Specifically, the feature amount acquisition unit 15 searches the coordinate group in which the length of the wall surface S is the shortest from the coordinate group of the wall surface S, obtains the total length when the coordinate groups are connected, and obtains the total length of the cable C The shortest total length L ′. Next, the feature quantity acquisition unit 15 obtains the total length L of the actual wiring of the cable C from the coordinate group of the midpoint of the cable C as shown in FIG. Then, the feature amount acquisition unit 15 calculates the total length L of the cable C in the past actual wiring and the total length L ′ of the cable C in the case where the cable C is temporarily wired so as to have the shortest length on the actually wired arrangement surface. The margin is obtained by obtaining the ratio of the total length L / the total length L ′. The margin obtained from the actual wiring is a margin margin in the actual wiring in which local pressure is not applied to the cable C, that is, a margin condition. The wiring verification unit 12 verifies the margin in the wiring design based on the margin condition.

  Further, when obtaining the separation distance in the actual wiring, the feature amount acquisition unit 15, as shown in FIG. 2 (a), for each coordinate of the midpoint of the cable C, the wall surface S located closest to the midpoint coordinate. Search for coordinates. Next, as shown in FIG. 2A, the feature amount acquisition unit 15 uses the coordinate group of the searched wall surface S and the coordinate group of the midpoint of the cable C for each coordinate of the midpoint of the cable C. Next, the isolation distance d is obtained. Then, the feature amount acquisition unit 15 obtains the shortest separation distance d among the obtained separation distances d. The shortest separation distance d obtained from the actual wiring is the limit separation distance d in the actual wiring in which the cable C is not affected by heat or dents from the wall surface S, that is, the separation distance condition. The wiring verification unit 12 verifies the isolation distance in the wiring design based on the isolation distance condition.

  When obtaining the bending radius in the actual wiring, the feature amount acquisition unit 15 starts from the coordinate group (see FIG. 2A) located at one end of the cable C from the coordinate group of the midpoint of the cable C. Choose three consecutive coordinates. Then, when the selected three coordinates are connected by a straight line, the feature amount acquisition unit 15 determines whether or not the angle formed by the straight lines is less than a predetermined angle (for example, 135 degrees) that is less than 180 degrees. To do. When the formed angle is equal to or smaller than the predetermined angle, the feature amount acquisition unit 15 obtains the bending radius R of the cable C using the selected three coordinates. Specifically, as shown in the enlarged view of FIG. 2A, the feature amount acquisition unit 15 connects the selected three coordinates with a straight line, and the vertical bisector of each side indicates the selected three coordinates. The center of the circumscribed circle that touches the selected three coordinates, that is, the point that intersects on the plane that includes. Next, the feature amount obtaining unit 15 obtains the bending radius R by obtaining the distance between the obtained center of the circumscribed circle and, for example, the second coordinate among the selected three coordinates. The feature amount acquisition unit 15 repeatedly executes this process until the coordinate (coordinate B) of the midpoint located at the other end of the cable C is selected as the third of the three coordinates, and the cable C The bending radius R at the coordinates of the middle point (excluding the coordinates of the middle points at both ends of the cable C) is obtained. Then, the feature amount acquisition unit 15 obtains the shortest bending radius R among the obtained bending radii R. The shortest bending radius R obtained from the actual wiring is a limit bending radius R in the actual wiring in which excessive pressure is not applied to the core of the cable C, that is, a bending radius condition. The wiring verification unit 12 verifies the bending radius in the wiring design based on the bending radius condition.

  When obtaining the fixed interval, the feature amount acquisition unit 15 fixes the fixed interval f, which is the distance between the adjacent fixtures T, from the coordinate group of the fixed position of the cable, as shown in FIG. It calculates | requires for every space | interval of tool T. Then, the feature amount acquisition unit 15 obtains the longest fixed interval f among the obtained fixed intervals f. The longest fixed interval f obtained from the actual wiring is a limit fixed interval f in the actual wiring that does not cause the cable C to loosen, that is, a fixed interval condition. The wiring verification unit 12 verifies the fixed interval in the wiring design based on the fixed interval condition.

  The identification information receiving unit 16 in FIG. 1 stores wiring information in association with the wiring route and the wiring condition (margin degree condition, isolation distance condition, bending radius condition, and fixed interval condition) obtained by the feature amount acquisition unit 15. The input of the cable information (identification information for identifying the actually wired cable, specifically, the cable name, the shape of the three-dimensional real space, and the cross-sectional shape of the three-dimensional real space) in the actual wiring stored in the unit 21, It receives from a designer via the input part 30. FIG. When the identification information receiving unit 16 receives the input of the cable information in the actual wiring, the identification information receiving unit 16 associates them with the wiring route and the wiring condition of the cable obtained by the feature amount acquisition unit 15, and stores the wiring information in the wiring information storage unit 21. Remember as.

  The feature amount display control unit 17 reads out the wiring route and the wiring condition of the cable from the wiring information storage unit 21 and displays them together with the design screen (screen for supporting the design for wiring the cable) displayed by the wiring design support unit 11. Displayed on the unit 40. Also. The feature amount display control unit 17 reads out the wiring condition used in the verification by the wiring verification unit 12 from the wiring information storage unit 21.

  Specifically, when the wiring design support unit 11 performs wiring design, the feature amount display control unit 17 performs cable information (cable name, three-dimensional virtual information) in the wiring design received by the wiring design support unit 11 at the start of design. The wiring route and the wiring condition of the cable are read from the wiring information storage unit 21 using the space shape and the cross-sectional shape of the three-dimensional virtual space. Then, the read wiring route and wiring condition of the cable are displayed on the display unit 40 together with the design screen displayed by the wiring design support unit 11.

  In addition, the feature amount display control unit 17 is a cable in the wiring design stored in the design information storage unit 22 in association with the design number received by the design information selection unit 14 at the time of verification by the wiring verification unit 12. Using the information (cable name, shape of the three-dimensional virtual space, and cross-sectional shape of the three-dimensional virtual space), the wiring condition is read from the wiring information storage unit 21.

  The storage unit 20 is a hard disk device, for example, and stores information received via the interface 50. The storage unit 20 includes a wiring information storage unit 21 and a design information storage unit 22.

  The wiring information storage unit 21 stores the cable routing route and wiring conditions (margin degree condition, isolation distance condition, bending radius condition, and fixed interval condition) in the actual wiring obtained by the feature quantity acquisition unit 15, and the identification information receiving unit 16. Stores the wiring information associated with the cable information (the cable name, the shape of the three-dimensional real space, and the cross-sectional shape of the three-dimensional real space) in the actual wiring accepted. This association is performed by the identification information receiving unit 16.

  As shown in FIG. 3, the wiring information stored in the wiring information storage unit 21 includes the names of cables that are actually wired, the shape of the three-dimensional real space, the cross-sectional shape of the three-dimensional real space, the wiring route of the cable, and the margin condition. , The separation distance condition, the bending radius condition, and the fixed interval condition.

  The design information storage unit 22 stores the design coordinate group acquired by the wiring design support unit 11, specifically the coordinates on the outer periphery of the cable designed for wiring in the three-dimensional virtual space, the fixed position of the cable designed for wiring. And the coordinates on the wall surface of the three-dimensional virtual space where the cable is designed for wiring, the cable information received by the wiring design support unit 11 at the start of design (the cable name, the shape of the three-dimensional virtual space, and the three-dimensional virtual space The design information associated with the sectional shape is stored. This association is performed by the wiring design support unit 11.

  As shown in FIG. 4, the design information stored in the design information storage unit 22 is composed of five pieces of information including a design number, a cable name, a shape of the three-dimensional virtual space, a cross-sectional shape of the three-dimensional virtual space, and a design coordinate group. Is done. The design number is automatically assigned by the arithmetic unit 10 when the design information is stored in the design information storage unit 22.

  Here, a method in which the wiring verification unit 12 obtains a margin, an isolation distance, a bending radius, and a fixed interval in the wiring design using the design coordinate group will be described.

  When obtaining the margin in the wiring design, the wiring verification unit 12 assumes that the wiring design shown in FIG. 2A is performed, the coordinate group (wall surface) of the placement surface in the three-dimensional virtual space included in the design coordinate group. The coordinate group in which the length of the wall surface S is the shortest is retrieved from the coordinate group of S, and the cable C is wired on the arrangement surface so that the total length of the cable C is the shortest as shown in FIG. In this case, the total length L ′ of the cable C is obtained. This is because the wiring verification unit 12 searches the coordinate group in which the length of the wall surface S is the shortest from the coordinate group of the wall surface S, obtains the total length when the coordinate groups are connected, and determines this as the shortest of the cable C. It can be obtained by setting the total length L ′. Next, the wiring verification unit 12 obtains the total length L in the wiring design of the cable C from the coordinate group of the midpoint of the cable C. Then, the wiring verification unit 12 calculates the total length L / the total length L ′ to obtain a margin in the wiring design.

  Further, when obtaining the separation distance in the wiring design, the wiring verification unit 12 assumes that the wiring design shown in FIG. 2A is being performed, with respect to the coordinate group of the midpoint of the cable C included in the design coordinate group. The nearest coordinate group of the wall surface S is searched for each coordinate of the middle point of the cable C, and the separation distance in the wiring design is determined using the retrieved coordinates of the wall surface S and the coordinate of the middle point of the cable C. d is obtained for each coordinate of the middle point of the cable C.

  Further, when obtaining the bending radius in the wiring design, the wiring verification unit 12 assumes that the wiring design shown in FIG. 2A is performed, from the coordinate group of the midpoint of the cable C included in the design coordinate group, Three consecutive coordinates are selected starting from the coordinates of the middle point (coordinate A) located at one end of the cable C. Then, when the three selected coordinates are connected by a straight line, the wiring verification unit 12 determines whether or not the angle formed by the two straight lines is less than a predetermined angle (for example, 135 degrees) less than 180 degrees. When the formed angle is equal to or smaller than the predetermined angle, the wiring verification unit 12 connects the three consecutive points with a straight line as shown in the enlarged view of FIG. Then, a point that intersects on a plane formed by three consecutive points, that is, the center of a circumscribed circle is obtained. Next, the wiring verification unit 12 obtains the bending radius R by obtaining the distance between the center of the obtained circumscribed circle and, for example, the second coordinate among the three consecutive coordinates. The wiring verification unit 12 repeatedly executes this until the midpoint coordinate (coordinate B in FIG. 2A) located at the other end of the cable C is selected as the third of the three coordinates. The bending radius R in the wiring design is obtained for each coordinate of each midpoint excluding the coordinates of the midpoint of both ends of the cable C.

  Furthermore, when obtaining the fixed interval in the wiring design, the wiring verification unit 12 assumes that the wiring design shown in FIG. The fixing interval f, which is the distance between the fixing tools T to be obtained, is obtained for each interval of the fixing tools T. In this way, the wiring verification unit 12 determines the fixed interval f in the wiring design.

  With the above-described method, the wiring verification unit 12 obtains a margin, an isolation distance, a bending radius, and a fixed interval in wiring design.

  The input unit 30 receives input of various information and various instructions from the designer. The input unit 30 is, for example, a keyboard.

  The display unit 40 displays various information. The display unit 40 is, for example, a liquid crystal display.

  The interface 50 receives a measurement coordinate group transmitted from an external measurement device.

  The bus line BL connects the arithmetic unit 10, the storage unit 20, the input unit 30, the display unit 40, and the interface 50 to each other.

  The operation of the design support apparatus 1 is as shown in FIG.

  First, the wiring design support unit 11 displays the three-dimensional virtual space on the display unit 40 and supports the design for wiring the cable on the arrangement surface in the three-dimensional virtual space. Specifically, the wiring design support unit 11 includes coordinates on the outer periphery of the cable wired in the three-dimensional virtual space, coordinates of the fixed position of the cable designed for wiring, and the three-dimensional virtual space where the cable is designed for wiring. The coordinates on the wall surface (design coordinate group) are acquired via the input unit 30.

  At this time, the wiring design support unit 11 also receives cable information (cable name, shape of the three-dimensional virtual space, and cross-sectional shape of the three-dimensional virtual space) in the wiring design. When the cable information in the wiring design is received by the wiring design support unit 11, the feature amount display control unit 17 uses the cable information to store the wiring route and the wiring condition of the cable in the actual wiring in the wiring information storage unit 21. It reads out from the stored wiring information and displays it on the display unit 40.

  When the wiring design completion from the designer is received by the wiring design support unit 11 via the input unit 30, the wiring design support unit 11 determines the design coordinate group and the wiring design received by the wiring design support unit 11 at the start of design. The cable information is associated and stored in the design information storage unit 22 as design information.

  Thereafter, when verification of the wiring design is instructed via the input unit 30, the wiring verification unit 12 determines whether the cable wiring design accepted by the wiring design support unit 11 can be applied as actual wiring. Verify using.

  At the time of verification, first, the design information selection unit 14 inputs a design number (see FIG. 4) that is information for specifying a cable wiring design (design coordinate group) to be verified by the wiring verification unit 12. The input from the designer via the unit 30 is accepted.

  Then, the wiring verification unit 12 acquires a design coordinate group stored in association with the design number received by the design information selection unit 14 from the design information storage unit 22, and from the acquired design coordinate group, in the wiring design. Find margin, separation distance, bend radius and fixed interval.

  Thereafter, the wiring verification unit 12 verifies whether or not the obtained margin, separation distance, bending radius, and fixed interval satisfy the wiring conditions. The wiring condition used here is determined by the feature amount display control unit 17 using the cable information stored in the design information storage unit 22 in association with the design number received by the design information selection unit 14. The wiring conditions are read from the wiring information stored in the storage unit 21.

  When the verification by the wiring verification unit 12 is completed, the verification result display unit 13 displays the verification result on the display unit 40.

  Here, the wiring information stored in the wiring information storage unit 21 includes the information obtained by the feature amount acquisition unit 15 (wiring conditions and the wiring route of the cable), and the cable information in the actual wiring received by the identification information receiving unit 16. Are generated by the identification information receiving unit 16 associating them.

  Further, the feature amount acquisition unit 15 obtains the wiring route and the wiring condition of the cable stored in the wiring information storage unit 21 using the measurement coordinate system received from the external measurement device via the interface 50.

  Next, wiring information processing for generating wiring information stored in the wiring information storage unit 21 will be described with reference to FIG. The wiring information processing is executed by the arithmetic unit 10 when a wiring information generation instruction from the designer is received via the input unit 30.

  In the wiring information processing, first, the calculation unit 10 (feature amount acquisition unit 15) acquires a measurement coordinate group from an external measurement device via the interface 50 (step S1).

  Next, the calculation unit 10 (feature quantity acquisition unit 15) obtains the cable routing route using the acquired measurement coordinate system (step S2). Specifically, the feature quantity acquisition unit 15 obtains a cable routing route as follows. That is, the calculation unit 10 (feature amount acquisition unit 15) obtains the shape of the wall surface S from the coordinates of the wall surface S in the three-dimensional real space included in the acquired measurement coordinate system. Moreover, the calculating part 10 (feature amount acquisition part 15) calculates | requires the shape of a cable from the coordinate on the outer periphery of a cable. The calculation unit 10 (feature amount acquisition unit 15) obtains the cable arrangement path (see FIG. 3) by combining the obtained shape of the cable and the obtained shape of the wall surface S (by overlapping).

  Thereafter, the calculation unit 10 (feature amount acquisition unit 15) obtains a margin condition using the acquired measurement coordinate system (step S3). Specifically, for example, when the actual wiring illustrated in FIG. 2A is performed, the calculation unit 10 (feature amount acquisition unit 15) calculates the wall surface S from the coordinate group of the wall surface S included in the acquired measurement coordinate system. 2 is searched for, and as shown in FIG. 2B, the total length L ′ of the cable C when the cable C is wired in the three-dimensional space so that the total length of the cable C is the shortest. Ask for. This is because the calculation unit 10 (feature value acquisition unit 15) searches the coordinate group having the shortest length of the wall surface S from the coordinate group of the wall surface S, and obtains the total length when the coordinate groups are joined together. Is the shortest overall length L ′ of the cable C. Next, the calculation unit 10 (feature amount acquisition unit 15) obtains the total length L of the actual wiring of the cable C from the coordinate group of the midpoint of the cable C. Then, the calculation unit 10 (feature amount acquisition unit 15) calculates the total length L / the total length L ′ to obtain a margin in the actual wiring. The calculation unit 10 (feature quantity acquisition unit 15) sets this as a margin condition.

  Next, the calculation unit 10 (feature amount acquisition unit 15) obtains an isolation distance condition using the acquired measurement coordinate system (step S4). Specifically, for example, when the actual wiring illustrated in FIG. 2A is performed, the calculation unit 10 (feature amount acquisition unit 15) determines the most of the midpoint coordinates for each of the midpoint coordinates of the cable C. The coordinates of the wall surface S located nearby are searched. Next, the calculation unit 10 (feature value acquisition unit 15) uses the obtained coordinate group of the wall surface S and the coordinate group of the midpoint of the cable C to determine the actual wiring for each coordinate of the midpoint of the cable C. Obtain the separation distance d. Then, the calculation unit 10 (feature quantity acquisition unit 15) obtains the shortest separation distance d among the obtained separation distances d in the actual wiring. The calculation unit 10 (feature quantity acquisition unit 15) uses the obtained shortest separation distance d as the separation distance condition.

  And the calculating part 10 (feature quantity acquisition part 15) calculates | requires a bending radius condition using the acquired measurement coordinate system (step S5). Specifically, for example, when the actual wiring illustrated in FIG. 2A is performed, the calculation unit 10 (feature amount acquisition unit 15) first determines one of the cables C from the coordinate group of the midpoint of the cable C. Three consecutive coordinates are selected starting from the coordinate A located at the end of. Then, when the selected three coordinates are connected by a straight line, the calculation unit 10 (feature amount acquisition unit 15) has an angle formed by the straight lines that is less than a predetermined angle (for example, 135 degrees) that is less than 180 degrees. It is determined whether or not. When the formed angle is equal to or smaller than the predetermined angle, the calculation unit 10 (feature amount acquisition unit 15) connects the selected three coordinates with a straight line, and the vertical bisector of each side indicates the selected three coordinates. The center of the circumscribed circle that touches the selected three coordinates, that is, the point that intersects on the plane that includes. Next, the calculation unit 10 (feature amount acquisition unit 15) obtains the distance between the center of the obtained circumscribed circle and, for example, the second coordinate of the selected three coordinates, thereby bending the actual wiring. The radius R is obtained. The feature amount acquisition unit 15 repeatedly executes this process until the coordinate (coordinate B) of the midpoint located at the other end of the cable C is selected as the third of the three coordinates, and the cable C The bending radius R at the coordinates of the middle point (excluding the coordinates of the middle points at both ends of the cable C) is obtained. The calculation unit 10 (feature quantity acquisition unit 15) sets the shortest bending radius R among the obtained bending radii R in the actual wiring as a bending radius condition.

  Next, the calculation unit 10 (feature quantity acquisition unit 15) obtains a fixed interval condition using the acquired measurement coordinate system (step S6). Specifically, for example, when the actual wiring illustrated in FIG. 2A is performed, the calculation unit 10 (feature amount acquisition unit 15) is adjacent to the coordinate group of the fixed position of the cable included in the measurement coordinate system. The fixing interval f, which is the distance between the fixing tools T to be obtained, is obtained for each interval of the fixing tools T. The calculation unit 10 (feature quantity acquisition unit 15) sets the longest fixed interval f among the determined fixed intervals f in the actual wiring as a fixed interval condition.

  Next, the calculation unit 10 (identification information receiving unit 16) corresponds to the cable wiring route and the wiring conditions (margin condition, isolation distance condition, bending radius condition, and fixed interval condition) obtained by the feature amount acquisition unit 15. An input screen for cable information (cable name, shape of three-dimensional real space and cross-sectional shape of three-dimensional real space) in the attached actual wiring is displayed on the display unit 40 (step S7). The shape of the three-dimensional real space is input as, for example, only a straight line, bent, or U-shaped, and the cross-sectional shape of the three-dimensional real space is input as, for example, a circle or a rectangle.

  And the calculating part 10 (identification information reception part 16) determines whether the cable information in actual wiring was input by the designer via the input part 30 (step S8).

  If the calculation part 10 (identification information reception part 16) determines with having input (step S8: Yes), it will transfer to step S9, and if it determines with not having input (step S8: No), it will return to step S7.

  In step S9, the arithmetic unit 10 (identification information receiving unit 16) inputs the cable information (cable name, shape of the three-dimensional real space, and cross-sectional shape of the three-dimensional real space) in the input actual wiring, and steps S2 to S6. In the wiring information storage unit 21 as wiring information, the wiring route and the wiring condition (margin degree condition, isolation distance condition, bending radius condition, and fixed interval condition) obtained by the feature amount acquisition unit 15 are associated with each other. Store (step S9).

  Thereafter, the arithmetic unit 10 ends this wiring information processing.

  Next, a wiring design process for performing wiring design will be described with reference to FIG. The wiring design process is executed by the arithmetic unit 10 when a wiring design start instruction is received via the input unit 30.

  In the wiring design process, first, the calculation unit 10 (wiring design support unit 11) determines the cable information in the wiring design, that is, the name of the cable used for the wiring design, the shape of the three-dimensional virtual space, and the cross-sectional shape of the three-dimensional virtual space. A screen for requesting input is displayed on the display unit 40, and input from the designer is received (step S21).

  Next, the arithmetic unit 10 (wiring design support unit 11) determines whether or not the reception of the input of the cable information in the wiring design is completed (step S22).

  If the arithmetic unit 10 (wiring design support unit 11) determines that the reception of the input is not completed (step S22: No), the processing unit 10 returns to step S21.

  On the other hand, when the arithmetic unit 10 (wiring design support unit 11) determines that the input has been received (step S22: Yes), the operation proceeds to step S23.

  In step S23, the calculation unit 10 (feature amount display control unit 17) uses the cable information (cable name, shape of the three-dimensional virtual space, and cross-sectional shape of the three-dimensional virtual space) in the wiring design input in step S21. The cable wiring path and the wiring conditions that match the input cable information are read from the wiring information storage unit 21 (step S23).

  Specifically, the calculation unit 10 (feature quantity display control unit 17) determines the cable name, the shape of the three-dimensional virtual space, and the three-dimensional virtual input from step S21 based on the wiring information stored in the wiring information storage unit 21. The cable name that matches the cross-sectional shape of the space, the shape of the three-dimensional real space, and the cross-sectional shape of the three-dimensional real space are searched. The calculation unit 10 (feature value display control unit 17) can search for the matching cable name, the shape of the three-dimensional real space, and the cross-sectional shape of the three-dimensional real space, that is, the cable information in the actual wiring (the cable in the actual wiring) When the information is stored in the wiring information storage unit 21), the cable wiring path and the wiring conditions stored in association with the cable information in the actual wiring are read from the wiring information storage unit 21.

  Next, the calculation unit 10 (feature amount display control unit 17) displays the cable wiring route and the wiring conditions read in step S23 together with the design screen displayed by the calculation unit 10 (wiring design support unit 11). 40 (step S24). Further, the arithmetic unit 10 (wiring design support unit 11) supports the wiring design by displaying the design screen (step S24).

  Thereafter, the arithmetic unit 10 (wiring design support unit 11) determines whether or not a wiring design completion instruction from the designer has been received by the input unit 30 (step S25).

  If the arithmetic unit 10 (wiring design support unit 11) determines that an instruction to complete the wiring design has not been received (step S25: No), the processing unit 10 returns to step S24.

  On the other hand, when the arithmetic unit 10 (wiring design support unit 11) determines that an instruction to complete the wiring design has been received (step S25: Yes), the design coordinate group at that time, that is, the wiring design in the three-dimensional virtual space. The coordinates on the outer periphery of the cable that has been designed, the coordinates of the fixed position of the cable that has been designed for wiring, and the coordinates on the wall surface of the three-dimensional virtual space in which the cable has been designed for wiring are represented by the cable name received in step S21, The information is stored in the design information storage unit 22 as design information in association with the shape of the space and the cross-sectional shape (cable information in the wiring design) of the three-dimensional virtual space (step S26).

  Thereafter, the arithmetic unit 10 (wiring design support unit 11) ends the wiring design process.

  Next, a wiring verification process for verifying whether the wiring design satisfies the wiring conditions will be described with reference to FIG. The wiring verification process is executed by the arithmetic unit 10 when a wiring verification instruction from the designer is received via the input unit 30.

  In the wiring verification process, first, the calculation unit 10 (design information selection unit 14) displays a screen requesting selection of a design number (see FIG. 4) used for verification on the display unit 40, and the selection by the designer is performed. Accept (step S41).

  Next, the calculation unit 10 (design information selection unit 14) determines whether or not the selection acceptance has been completed (step S42).

  If the calculation part 10 (design information selection part 14) determines with selection reception not being completed (step S42: No), it will return to step S41.

  On the other hand, if the calculating part 10 (design information selection part 14) determines with selection reception having been completed (step S42: Yes), it will transfer to step S43.

  In step S43, the calculation unit 10 (wiring verification unit 12) acquires the cable wiring design (design coordinate group) stored in the design information storage unit 22 in association with the selected design number, and performs wiring design. A margin, a separation distance, a bending radius, and a fixed interval are obtained (step S43).

  Specifically, for example, when the wiring design illustrated in FIG. 2A is performed, the arithmetic unit 10 (wiring verification unit 12) obtains a margin in the wiring design by the above-described method. That is, the calculation unit 10 (wiring verification unit 12) searches the coordinate group in which the length of the wall surface S is the shortest from the coordinate group (coordinate group of the wall surface S) of the three-dimensional virtual space included in the design coordinate group. The total length when the coordinate groups are connected is obtained, and this is defined as the shortest total length L ′ of the cable C. Next, the calculation unit 10 (wiring verification unit 12) obtains the total length L in the actual wiring of the cable C from the coordinate group of the midpoint of the cable C. Then, the calculation unit 10 (wiring verification unit 12) calculates the total length L / the total length L ′ to obtain a margin in the wiring design.

  For example, when the wiring design shown in FIG. 2A is performed, the arithmetic unit 10 (wiring verification unit 12) obtains an isolation interval in the wiring design by the above-described method. That is, the calculation unit 10 (wiring verification unit 12) determines the coordinate group of the wall surface S located closest to the coordinate group of the midpoint of the cable C included in the design coordinate group for each coordinate of the midpoint of the cable C. The isolation distance d in the wiring design is obtained for each coordinate of the midpoint of the cable C using the coordinates of the searched wall surface S and the midpoint of the cable C.

  For example, when the wiring design shown in FIG. 2A is performed, the calculation unit 10 (wiring verification unit 12) obtains the bending radius in the wiring design by the above-described method. That is, the calculation unit 10 (wiring verification unit 12) starts from the midpoint coordinate group (coordinate A) located at one end of the cable C from the midpoint coordinate group of the cable C included in the total coordinate group. Select three consecutive coordinates. Then, when the arithmetic unit 10 (wiring verification unit 12) connects the selected three coordinates with a straight line, the angle formed by the two straight lines is less than a predetermined angle (for example, 135 degrees) less than 180 degrees. Determine whether. When the formed angle is equal to or smaller than a predetermined angle, the calculation unit 10 (wiring verification unit 12) connects three consecutive points with straight lines as shown in the enlarged view of FIG. The point where the bisectors intersect on a plane formed by three consecutive points, that is, the center of the circumscribed circle is obtained. Next, the calculation unit 10 (wiring verification unit 12) obtains a distance between the center of the obtained circumscribed circle and, for example, the second coordinate out of the three consecutive coordinates, so that the bending radius in the wiring design is obtained. Find R. The calculation unit 10 (wiring verification unit 12) selects this until the coordinate of the midpoint located at the other end of the cable C (coordinate B in FIG. 2A) is selected as the third of the three coordinates. , Repeatedly, the bending radius R at the coordinates of each midpoint excluding the coordinates of the midpoint at both ends of the cable C is obtained.

  Further, for example, when the wiring design shown in FIG. 2A is performed, the calculation unit 10 (wiring verification unit 12) obtains a fixed interval in the wiring design by the above-described method. That is, the calculation unit 10 (wiring verification unit 12) calculates a fixed interval f, which is a distance between adjacent fixtures T, for each interval of the fixtures T from the coordinate group of the fixed positions of the cables included in the design coordinate group. This is determined as a fixed interval in the wiring design.

  In this way, the calculation unit 10 (wiring verification unit 12) uses the design coordinate group stored in the design information storage unit 22 in step S43, and uses the design coordinate group stored in the design information storage unit 22 to determine the margin and the separation distance (the middle point of the cable). For each coordinate), the bending radius (for each coordinate of the middle point excluding the coordinates of the middle point at both ends of the cable), and the fixed interval (for each interval of the fixture) are obtained.

  After execution of step S43, the calculation unit 10 (feature amount display control unit 17) executes the following processing in step S44. That is, the calculation unit 10 (feature amount display control unit 17) stores the cable information (the cable name, the shape of the three-dimensional virtual space, and the three-dimensional virtual space) in the wiring design stored in association with the design number selected in step S41. The sectional shape of the space is acquired from the design information storage unit 22. Thereafter, the calculation unit 10 (feature value display control unit 17) searches the wiring information storage unit 21 for cable information in actual wiring that matches the cable information in the acquired wiring design. When matching cable information can be searched from the wiring information storage unit 21, the calculation unit 10 (feature amount display control unit 17) stores the wiring condition (corresponding to the cable information in the searched actual wiring) ( The margin condition, the separation distance condition, the bending radius condition, and the fixed interval condition) are read from the wiring information storage unit 21 (step S44).

  In step S44, for example, when design 1 (see FIG. 4) is selected in step S41, the calculation unit 10 (feature amount display control unit 17) transmits the cable from the design information storage unit 22 as cable information in the wiring design. Name: Cable A, 3D virtual space shape: straight line only, 3rd virtual real space cross-sectional shape: obtain three pieces of information (see FIG. 4), and the cable information in the actual wiring that matches this information is wiring information A search is made from the storage unit 21 to read the wiring conditions. As a result, the calculation unit 10 (feature amount display control unit 17) reads out the margin condition: 1.1, the separation distance condition: 10 mm, the bending radius condition: none, and the fixed interval condition: 50 mm as the wiring conditions (FIG. 3). reference).

  In step S44, for example, when design 2 (see FIG. 4) is selected in step S41, the calculation unit 10 (feature amount display control unit 17) from the design information storage unit 22 as cable information in wiring design. , Cable name: cable A, three-dimensional virtual space shape: bent, cross-sectional shape of three-dimensional virtual space: circular information (see FIG. 4) is acquired (see FIG. 4), and cable information in the actual wiring that matches this is wired A search is made from the information storage unit 21 to read the wiring conditions. As a result, the calculation unit 10 (feature amount display control unit 17) reads out the margin condition: 1.5, the separation distance condition: 13 mm, the bending radius condition: 35 mm, and the fixed interval condition: 35 mm as the wiring conditions (FIG. 3). reference).

  In addition, when the design 3 (see FIG. 4) is selected in step S41 in step S44, for example, the calculation unit 10 (feature amount display control unit 17) performs design information storage unit 22 as cable information in the wiring design. 3 information of cable name: cable C, shape of 3D virtual space: bending, cross-sectional shape of 3D virtual space: rectangle (see FIG. 4), and cable information in actual wiring that matches this is obtained. A search is performed from the wiring information storage unit 21 and the wiring conditions are read out. As a result, the calculation unit 10 (feature value display control unit 17) cannot perform a search because the matching wiring condition is not stored in the wiring information storage unit 21 (see FIG. 3). For this reason, the calculating part 10 (feature quantity display control part 17) does not read wiring conditions by step S44.

  After execution of step S44, the calculation unit 10 (wiring verification unit 12) determines whether or not the wiring conditions are read by the calculation unit 10 (feature amount display control unit 17) (step S45).

  If the calculation unit 10 (wiring verification unit 12) determines that the wiring condition is not read (step S45: No), it is determined that the wiring condition for verification is not stored in the wiring information storage unit 21. And a message indicating that the wiring design cannot be verified is displayed on the display unit 40 (step S54), and the wiring verification process is terminated.

  On the other hand, when the arithmetic unit 10 (wiring verification unit 12) determines that the wiring condition has been read (step S45: Yes), the margin in the wiring design obtained in step S43 is the margin read in step S44. It is determined whether or not the degree condition is exceeded (step S46).

  If the calculation unit 10 (wiring verification unit 12) determines that the margin in the obtained wiring design is equal to or greater than the margin condition (step S46: Yes), the calculation unit 10 (the wiring verification unit 12) sets a margin that does not apply local pressure to the cable. Since the wiring design has, the process proceeds to step S48.

  On the other hand, when the arithmetic unit 10 (wiring verification unit 12) determines that the margin in the obtained wiring design is less than the margin condition (step S46: No), there is a possibility that local pressure is applied to the cable. Since it is a wiring design, the process proceeds to step S47.

  In step S47, the arithmetic unit 10 (verification result display unit 13) displays a message indicating that the margin is insufficient on the display unit 40 (step S47), and proceeds to step S48.

  In step S48, the calculation unit 10 (wiring verification unit 12) determines whether the separation distance in the wiring design obtained in step S43 is equal to or greater than the separation distance condition read in step S44. A determination is made for each coordinate (step S48).

  When the calculation unit 10 (wiring verification unit 12) determines that the isolation distance in the calculated wiring design is equal to or greater than the isolation distance condition in all the coordinates of the midpoint of the cable (step S48: Yes), the calculation from the wall surface S Since it is a wiring design having an isolation distance in which the cable is not affected by heat or dents, the process proceeds to step S50.

  On the other hand, if there is at least one isolation distance that is less than the isolation distance condition among the obtained isolation distances in the wiring design (step S48: No), the calculation unit 10 (wiring verification unit 12) Since the wiring design has a possibility that the cable is affected by the depression or the like, the process proceeds to step S49.

  In step S49, the calculation unit 10 (verification result display unit 13) displays the location (coordinate of the middle point of the cable) that is less than the isolation distance condition together with a message indicating that the isolation distance is insufficient. (Step S49), and the process proceeds to Step S50.

  In step S50, the calculation unit 10 (wiring verification unit 12) determines whether the bending radius in the wiring design obtained in step S43 is equal to or larger than the bending radius condition read in step S44. A determination is made for each coordinate (excluding the coordinates of the midpoints at both ends of the cable) (step S50).

  The calculation unit 10 (wiring verification unit 12) has the bending radius in the obtained wiring design equal to or greater than the bending radius condition at all the coordinates of the midpoint of the cable (excluding the coordinates of the midpoint of both ends of the cable). Is determined (step S50: Yes), the wiring design has a bending radius that does not apply excessive pressure to the core of the cable, and the process proceeds to step S52.

  On the other hand, if there is even one bending radius that is less than the bending radius condition among the bending radii in the obtained wiring design (step S50: No), the calculation unit 10 (wiring verification unit 12) is excessive in the core of the cable. Since the wiring design has the possibility of applying pressure, the process proceeds to step S51.

  In step S51, the calculation unit 10 (verification result display unit 13) displays the location (coordinate of the midpoint of the cable) where the bending radius is less than the display unit 40 together with a message indicating that the bending radius is insufficient. (Step S51), and the process proceeds to step S52.

  In step S50, when the bending radius condition is not read (for example, design 1 (see FIG. 4) is selected in step S41, and in step S44, the margin condition: 1.1, as the wiring condition) When the separation distance condition: 10 mm, the bending radius condition: none, and the fixed interval condition: 50 mm are read (see FIG. 3)), the calculation unit 10 (wiring verification unit 12) skips the determination in step S50, Control goes to step S52.

  In step S52, the calculation unit 10 (wiring verification unit 12) determines whether or not the fixed interval in the wiring design obtained in step S43 is equal to or less than the fixed interval condition read in step S44. (Step S52).

  If the arithmetic unit 10 (wiring verification unit 12) determines that the fixed interval in the obtained wiring design is equal to or less than the fixed interval condition at all intervals (step S52: Yes), the fixed interval that does not cause the cable to loosen is determined. Since the wiring design has, the process proceeds to step S55.

  On the other hand, if there is at least one fixed interval exceeding the fixed interval condition among the fixed intervals in the obtained wiring design (step S52: No), the arithmetic unit 10 (wiring verification unit 12) can cause the cable to loosen. Since the wiring design has the characteristics, the process proceeds to step S53.

  In step S53, the calculation unit 10 (verification result display unit 13) displays the location (the coordinates of the fixture) that forms a fixed interval exceeding the fixed interval condition on the display unit 40 together with a message that the fixed interval is too wide. (Step S53), the process proceeds to Step S55.

  In step S55, the arithmetic unit 10 (CPU) determines whether or not an instruction to end the wiring verification process has been received by the input unit 30 (step S55).

  When the calculation unit 10 (CPU) determines that the instruction to end the wiring verification process is not received by the input unit 30 (step S55: No), the display of the message performed on the display unit 40 is maintained. The determination in step S55 is repeated.

  On the other hand, when the arithmetic unit 10 (CPU) determines that the instruction to end the wiring verification process is received by the input unit 30 (step S55: Yes), the message displayed on the display unit 40 is deleted, and this wiring verification is performed. End the process.

That is, the shortest total length L ′ of the cable is determined, for example, from the coordinate group of the wall surface S to the coordinate group having the longest length of the wall surface S (the coordinates of the wall surface S on the left side and the lower side of L ′ in FIG. 2B). Group) and the coordinate groups may be connected to each other. In this case, since the total length L ′ is longer than that in the shortest case, the margin condition is lowered. Therefore, it is effective when performing wiring design corresponding to actual wiring that does not require much margin.
