Description

  The present invention provides an indoor wiring design system, a central device, which can effectively arrange a wiring unit in which indoor harnesses are aggregated, and can easily and reliably exchange data between a floor planner and an indoor wiring designer. The present invention relates to an indoor wiring design method and a computer program.

  With the recent spread of electric equipment, the number of electrical processes in building a house is rapidly increasing. In particular, at the time of enforcement of indoor wiring, various members such as necessary indoor harnesses, outlets, switches, etc. were brought into the enforcement site, and indoor wiring was performed while processing to match the layout at the site.

  However, when wiring processing is performed on site, there is a problem that a large amount of waste material is generated due to the processing, and the number of man-hours for waste material disposal increases. In addition, there is a problem in that it is difficult to secure a craftsman because skill is required for an operator in order to accurately perform on-site alignment.

In order to solve such a problem, for example, in the same way as the LAN laying method disclosed in Patent Document 1, a wiring unit in which indoor wiring harnesses for indoor wiring are used and the length of the indoor harness from the position where the wiring unit is attached By determining the length at the design stage, it is not necessary to perform on-site adjustment, and it is possible to perform indoor wiring work without waste.

  FIG. 4 is a flowchart showing a processing procedure of the CPU 11 of the central apparatus 1 of the indoor wiring design system according to the embodiment of the present invention. The CPU 11 of the central device 1 accepts floor plan information from the terminal device 3 as drawing data (step S401). In addition, the CPU 11 receives information related to the arrangement of the electric appliances corresponding to the floor plan information from the terminal device 3 (step S402) and stores the information in the electric appliance information storage unit 121 of the storage unit 12.

  FIG. 5 is a view showing an example of the data configuration of the appliance information storage unit 121 according to the embodiment of the present invention. In the example of FIG. 5, for each room ID that is information for identifying a room of the accepted floor plan, information on the position of an electric appliance such as an outlet, the type of electric wire used, and the like are stored. . In the example of FIG. 5, the information regarding the position of the electric appliance is stored as a three-dimensional coordinate value with the predetermined position of the room as the origin.

  The CPU 11 generates a constraint condition for wiring based on the floor plan information received from the terminal device 3 (step S403), and stores it in the constraint condition storage unit 122 of the storage unit 12. Here, the restriction condition is that when indoor harnesses that are wired indoors are wired using a wiring unit that is bundled in a bundle, the indoor harnesses are wired linearly to minimize the length of the indoor harness. This means a condition that makes it difficult, for example, information on the presence of a window, the presence of an atrium.

  FIG. 6 is an exemplary diagram of a data configuration of the constraint condition storage unit 122 according to the embodiment of the present invention. In the example of FIG. 6, for each room ID, which is information for identifying a room in the floor plan that has been received, information relating to positions such as windows and atriums, which are constraint conditions, is stored. In the example of FIG. 6, information regarding positions such as windows and atriums is stored as three-dimensional coordinate values with a predetermined position in the room as the origin.

  The CPU 11 determines the number of the wiring units and the indoor harness from the wiring units to the appliances based on the information on the arrangement of the appliances stored in the appliance information storage unit 121 and the constraint conditions in the wiring stored in the constraint condition storage unit 122. The position where the wiring unit is arranged is calculated so that the total of the lengths is minimized (step S404). The CPU 11 outputs the calculated position for arranging the wiring unit, for example, the coordinate value to the output means 15 (step S405). For example, the following method is used as a calculation method of the position where the wiring unit is arranged.

  FIG. 7 is a flowchart showing a procedure for calculating the position where the wiring unit of the CPU 11 of the central apparatus 1 of the indoor wiring design system according to the embodiment of the present invention is arranged. The CPU 11 of the central device 1 selects the room ID of the room for which the arrangement position of the wiring unit is to be calculated (step S701), and queries the appliance information storage unit 121 and the constraint condition storage unit 122 using the room ID as key information. Then, information on the position of the electric appliance to be arranged and the constraint condition are extracted (step S702).

  The CPU 11 calculates the coordinate value of the approximate center of the ceiling surface of the room whose wiring unit is to be calculated as the initial position for arranging the wiring unit (step S703). CPU11 calculates the routing length of each indoor harness at the time of arrange | positioning a wiring unit to the calculated coordinate value (step S704).

  FIG. 8 is a diagram schematically showing a method for calculating the indoor harness routing length, and FIG. 8A is a partial plan view of a room for calculating the arrangement position of the wiring unit. (B) is the partial side view of the room used as the object which calculates the arrangement position of a wiring unit.

  In FIG. 8, the wiring unit A is arranged on the ceiling, and the indoor harness is routed along the ceiling surface and wall surface to each electric appliance arranged in the room, for example, the lighting A1 and the outlet A2. In order to route the indoor harness so that the length of the indoor harness becomes the shortest when there is no blow-through B on the ceiling surface or when there is no window W on the wall surface, the indoor harness is linearly routed to the lighting A1 and the outlet A2. It is preferable. Such shortest paths are designated as routing paths P1 and P2.

  However, depending on the extracted constraint conditions, there may be a case where a blow-through B is present on the ceiling surface and a window W is present on the wall surface along the routing paths P1 and P2. In this case, in order to route the indoor harness so as to be the shortest, the indoor harness is routed to the lighting A1 and the outlet A2 via the detour routes Q1 and Q2. The CPU 11 calculates the routing length including the detour routes Q1 and Q2 based on the extracted constraint conditions.

  The CPU 11 determines whether there is an indoor harness whose calculated routing length is longer than a first limit value, for example, 30 m (step S705), and the CPU 11 is indoors whose routing length is longer than the first limit value. If it is determined that a harness is present (step S705: YES), the CPU 11 should wire the electrical appliance connected by the indoor harness whose routing length is longer than the first limit value by the indoor harness from another wiring unit. The indoor harness routing length is excluded from the calculation target (step S706). This makes it possible to design indoor wiring with a minimum number of wiring units when designing a wiring in a room where a plurality of wiring units need to be arranged, for example, in a hall, a large living room, etc. It can be minimized.

  When the CPU 11 determines that there is no indoor harness whose routing length is longer than the first limit value (step S705: NO), the CPU 11 calculates the total routing length (step S707).

  The CPU 11 determines whether the calculated total length of the indoor harness is smaller than the second limit value (step S708). When the CPU 11 determines that the total route length of the indoor harness is smaller than the second limit value (step S708: YES), the CPU 11 stores the calculated total route length in the RAM 13 as the second limit value. (Step S709), the arrangement of the wiring units is changed according to a predetermined rule (Step S710), and the process returns to Step S704. The second limit value is a numerical value for obtaining the minimum value of the total routing length, and is preferably set to an excessive value, for example, 200 m as an initial value.

  When the CPU 11 determines that the total length of the indoor harness is greater than or equal to the second limit value (step S708: NO), the CPU 11 returns to step S405 and stores the second limit value stored in the RAM 13. The coordinate value at which the wiring unit having been calculated is output to the output unit 15 as the calculation result of the arrangement position of the wiring unit (step S405).

  FIG. 9 is a flowchart showing a procedure for changing the position where the wiring unit of the CPU 11 of the central apparatus 1 of the indoor wiring design system according to the embodiment of the present invention is arranged. The CPU 11 of the central device 1 updates the coordinate value of the wiring unit placement position to the coordinate value of the grid point that is a unit distance away from the placed position (step S901).

  FIG. 10 is a diagram showing a changeable position when the arrangement position of the wiring unit is changed to a grid-like position with an interval of 1 m. As shown in FIG. 10, when the arrangement position of the wiring unit is R, the wiring unit is changed to one of eight positions R1 to R8 of the vertical and horizontal lattice points. The CPU 11 calculates the total length of the wiring unit for each lattice point that is the change position (step S902).

  The CPU 11 determines whether or not the shortest route length total among the calculated route length totals at the eight locations is smaller than the minimum value stored in the RAM 14, that is, the second limit value (step S903). ). When the CPU 11 determines that it is small (step S903: YES), the CPU 11 moves the arrangement position of the wiring unit to a grid point position smaller than the second limit value (step S904), and the calculated total drawing length is calculated. The total of the shortest routing length is stored in the RAM 14 as the second limit value, that is, the minimum value (step S905). CPU11 returns a process to step S704, and repeats the process mentioned above.

  When the CPU 11 determines that the shortest route length total among the calculated route length totals at eight locations is equal to or greater than the minimum value stored in the RAM 14, that is, the second limit value (step S903: NO) The CPU 11 determines that the current coordinate value of the arrangement position of the wiring unit is optimal, and does not change the arrangement position of the wiring unit.

  Note that the above-described repetitive processing for specifying the arrangement position of the wiring unit may be provided with a counter that counts the number of times of processing, and the processing may be terminated when it is repeated a predetermined number of times. This is because depending on the unit length for specifying the virtual grid-like arrangement position, it may be assumed that the position is not uniquely determined. In terms of mounting, if the process is repeated three times, it is possible to specify the arrangement position of the wiring unit in which the total length of the drawing is close to the minimum value.

  It is preferable that the CPU 11 stores the acquired floor plan information in the storage unit 12 and adds the calculated position where the wiring unit is arranged to the floor plan information. That is, although the coordinate value is memorize | stored by the three-dimensional coordinate, the height which installs for every electric appliance has the fixed value in most electric appliances. Therefore, for example, when the electric appliance is an outlet, the height is a constant value of 15 cm, and when the electric appliance is an illumination, the fact that the height is a constant value of 2 m is stored in the electric appliance information storage unit 121. Thus, it is possible to specify the height to be installed as long as the electric appliance is identified.

  Therefore, it is stored in the storage means 12 that the height at which the placement unit is placed is about 2.5 m on the ceiling surface. Then, by plotting the plane coordinate value of the arrangement unit on the floor plan as shown in FIG. 8A and outputting it from the output means 15, the drawing data which is the floor plan information received from the floor planner is obtained. The wiring design company plots the arrangement coordinates of the electric appliance including the wiring unit. Accordingly, different business entities can use the common drawing data to perform design work on the same house, and the design work can be efficiently performed without considering data compatibility.

  In the present embodiment, as in the ASP service, a drawing creation program is introduced into the central apparatus 1, and the terminal apparatus 3, 3,... Performs design work using a common program. However, the present invention is not limited to such a form. For example, a simple common drawing creation software is installed in the terminal devices 3, 3,. The same effect can be expected even in the case of centralized management in 1.
