When mounting the joint box and the electric appliance on the building unit 201 shown in FIG. 5, when checking the length of the electric wire wired between the joint box and the electric appliance, the operator operates the floor plan input section 11. Enter the floor plan information of the unit house (step S
1).

When the floor plan input unit 11 is operated, the calculation unit 20 controls the display device 32 to start displaying. While looking at the display device 32, the operator first draws the outer wall of the unit house, and inputs a plan of the stairs or the entrance of the unit house, which is registered in advance, on the outer wall.

After inputting the floor plan information of the unit house,
The operator operates the JB attachment position input section 12 to
The respective mounting positions of the joint boxes are input on the floor plan of the display device 32 (step S2).

After that, the operator operates the electric appliance information input unit 13 to select one wiring pattern from the wiring patterns registered in advance in the calculation unit 20 (step S3).

Next, the operator inputs the mounting position and height of the electric equipment used for this wiring pattern on the floor plan of the display device 32 (step S4).

The symbol mark of the electric appliance is stored in advance in the calculation unit 20, and the calculation unit 20 draws this symbol mark on the floor plan. Then, the operator selects the joint box for the connection pattern selected in step S3 from the joint boxes at the respective mounting positions input in step S2 (step S).

Next, the calculation unit 20 sets the coordinate system including the entire unit house on the floor plan of the display device 32 (step S13). At this time, the lower left of the floor plan is the origin. For example, in the case of the floor plan shown in FIG.
Is the origin. After step S13, the calculation unit 20 obtains the coordinates of the ceiling portion where wiring cannot be performed on the floor plan of the display device 32 (step S14). As places where wiring is not possible, there are, for example, a portion outside the outer wall 1 in FIG. 4, a portion 2 of an indoor staircase, and a portion 3 having no ceiling due to a stairwell.

After step S14, the calculation section 20 displays
As shown in, the coordinates of the electric appliance 4 and the coordinates of the joint box 5 are compared to determine where the joint box 5 is located on the left, right, up, and down as viewed from the electric appliance 4 (step S15). In this case, the joint box 5
It is in the upper right direction. The wiring route from the electric appliance 4 is extended vertically and horizontally toward the position of the joint box 5 determined in step S15, and the wiring route is determined (step S16).

At this time, in step S16, first, the wiring path is extended in either the left or right direction toward the direction in which the joint box 5 is present. In FIG. 4, the wiring path extends in the right direction. When the wiring route 101 is extended to the non-routable portion 3, the route is then changed to extend the wiring in either the upper or lower direction. Since it is determined in step S15 that the joint box 5 is at the upper right, the wiring path 102 is extended upward in FIG. When the wiring route 102 is extended to the non-wiring portion 2 again, the route is changed to extend the wiring route in either the left or right direction. In the case of FIG. 4, the wiring path 103 is extended in the direction in which the joint box 5 exists, that is, in the right direction. And the wiring route 1
When 03 reaches the point where it intersects with the coordinates of the joint box 5, the wiring path 104 is directed toward the joint box 5.
Prolong.

In this way, the calculation unit 20 extends the wiring path to the joint box 5 while changing the wiring path in the left-right direction or the vertical direction.

The calculating unit 20 sets the routes 101 to 104 extending from the electric appliance 4 to the joint box 5 as the wiring route 110 of the electric wire, and calculates the length of the wiring route 110 (step S17). After this, the calculation unit 20
5, the sum of the length of the wiring route 120 of the wall portion 6 calculated in step S11 and the length of the wiring route 110 of the ceiling portion 7 is calculated (step S18), and the length of the entire wiring route is calculated. Calculate the

At this time, as shown in FIG. 6, when the wiring route extends from the building unit 201 to the building unit 202, the calculation unit 20 calculates the amount of the straddling on the ceiling in step 18 as a whole. Add to the length of. The straddle is the difference between the two-dot chain line portion 110 and the solid line portion 130 on the ceiling of the building units 201 and 202 shown in FIG.

After this series of steps is completed, step S
When the process in 6 is completed, the calculated length is made to have a certain margin, that is, a predetermined length is added to the calculated length to obtain the required electric wire length (step S7).

The calculating section 20 displays the wiring route obtained in step S17 on the floor plan displayed by the display device 32, and also displays the wire length obtained in step S7 on the display device 32 (step S8). ).

The calculation unit 20 also causes the output device 31 to output the drawing displayed on the display device 32. further,
The calculation unit 20 saves the floor plan information, the joint box mounting position information, the electric appliance information, the calculated electric wire length, and the like in a file.

In this way, according to this embodiment, the length of the electric wire required for indoor wiring can be calculated. At this time, since the required wiring length is automatically calculated, the length of the electric wire can be determined without excess or deficiency.

Furthermore, since the length of the electric wire is automatically calculated only by inputting the information, it is not necessary for the operator to have knowledge of housing construction, and the operator who conducts the electric wiring can calculate the electric wire length. It can be unnecessary.
