[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a unit type building that supports an operation of creating an equipment part and an equipment diagram representing a mutual connection of the equipment parts on a plan view of a unit type building constructed by combining a plurality of box-shaped building units. It is related with the CAD system for equipment drawing preparation.
[0002]
[Background]
Conventionally, a unit type building constructed by combining a plurality of box-shaped (for example, rectangular parallelepiped) building units manufactured at a factory at a construction site has been used.
As shown in FIG. 10, the building unit of the unit type building includes a rectangular parallelepiped frame 14 in which upper and lower ends of pillars 11 at four corners are connected by an upper beam 12 and a lower beam 13. A material, a floor surface material, an outer wall material, and a partition wall are attached, thereby forming a living room or the like.
According to such a unit-type building, most of the work that has conventionally been done at the construction site can be done at the factory, so the work at the construction site can be remarkably reduced and a high-quality building can be built in a short period of time. There is an advantage.
[0003]
In order to secure the advantages of this unit-type building, the products (unit-type buildings) provided to customers are ready-made, thereby limiting the types of products to be designed and manufactured, and high efficiency in design work and manufacturing work. However, this makes it difficult to adequately meet the diverse needs of customers.
Therefore, CAD is designed to support design work so that the efficiency of design work can be sufficiently secured when designing and designing unit-type buildings one by one according to customer requirements, as in general custom-built construction. The system is being used.
[0004]
The CAD system used for the design of unit buildings is a basic design system that performs basic design of the building while meeting with the owner, and a production preparation system that determines detailed specifications based on the basic design and prepares the production of building units. And.
Then, with such a CAD system, a plan view showing the planar arrangement state of each building unit and the layout of the interior of each building unit is created for each floor, and the arrangement of equipment parts such as electricity, gas, water supply, air conditioning, etc. An equipment diagram is created on the plan view showing the interconnections of parts, such as wiring and piping.
[0005]
Specifically, a salesperson (so-called dealer) asks the owner's intention to arrange a floor plan of the building and the layout of the building unit, and to arrange the equipment parts such as electricity and gas according to the building layout. A facility diagram to be represented is created by the basic design system described above.
On the other hand, the manufacturer person in charge uses the production preparation system to write wall thickness, material specifications, etc. on the floor plan based on the floor plan and equipment drawing created by the basic design system, and according to the arrangement of equipment parts. Write the connections such as wiring, piping, etc. to the equipment diagram and modify it so that it can be used for production of building units in the factory.
[0006]
Here, when creating an equipment diagram using the basic design system and production preparation system described above, a grid formed by dividing the interior of the building unit at a predetermined pitch is virtually set in the plan view of the unit type building. .
Then, the operator who is in charge of equipment drawing selection selects the equipment parts to be placed on the display screen of the CAD system, designates one of the grid intersections of the grid and instructs the placement of the equipment parts, and displays the equipment drawing. Create it.
[0007]
According to such a CAD system, necessary equipment parts can be arranged simply by designating grid intersections, so that the creation of equipment diagrams by the CAD system can be greatly reduced, and a virtual grid can be set. Since the building unit is formed by dividing the building unit at a predetermined pitch, the arrangement of equipment parts in the building unit is regularized, and the productivity of the building unit in the factory can be improved.
[0008]
[Problems to be solved by the invention]
However, when an equipment diagram is created by the CAD system described above, there are the following problems.
For example, as shown in FIG. 11, in order to input the three-way connection switches 101 and 102 and the illumination 103 on the plan view, the switches 101 and 102 are previously connected to the three-way connection three-way switch (three terminals are connected). And a line segment that connects the switch symbol and the illumination symbol is input after determining whether it is a single-path switch (switch having two terminals) or not. .
For this reason, when the switches 101 and 102 are input, it is necessary to select whether the switch is a three-way switch or a single-way switch. It was.
[0009]
Further, the three-way connection as shown in FIG. 11 is often used as a lighting circuit for a staircase so that lighting can be turned on and off by any switch provided on the upper floor and the lower floor.
Conventionally, in the CAD system, when these inputs are performed, the switch 101 is input to the lower floor plan, and the switch 102 and the illumination 103 are input to the upper floor plan. Since the switch 101 is not represented in the upper floor plan, there is a problem that the relationship with the illumination 103 cannot be automatically represented.
For this reason, since the input operation for relating them must be performed separately, the operator's input man-hours increase, and there is a problem that it takes a lot of time to create the facility diagram.
[0010]
An object of the present invention is to provide a CAD system for creating a facility building drawing of a unit type building that can reduce an operator's input burden, cause no erroneous input, and can efficiently create a facility drawing.
[0011]
[Means for Solving the Problems]
The CAD system for creating facility diagrams according to the present invention will be described with reference to the reference numerals of the drawings. On the plan view of a unit type building constructed by combining a plurality of box-shaped building units, A CAD system for creating equipment diagrams for unit type buildings that supports the work of creating equipment diagrams representing mutual connections, instructing the input of lighting CL and switches SW1 and SW2 on the plan view, When two switches SW1 and SW2 are connected to one illumination CL by the equipment component input instructing means 331 for instructing input of the wirings L1 and L2 to be connected and the equipment parts input instructing means 331, a three-way connection is established. Three-way connection discriminating means 333 for discriminating the presence When the three-way connection discriminating means 333 discriminates that it is a three-way connection, the switches SW1 and SW2 are displayed as symbols of the three-way switch. It is characterized by that.
[0012]
According to this configuration, when two switches SW1 and SW2 are connected to one illumination CL, it is determined that the switch is a three-way connection. Therefore, when the switches SW1 and SW2 are input, the switches SW1 and SW2 are input. It is not necessary to determine whether SW2 is a three-way switch or a single-way switch. Therefore, the input burden on the operator can be reduced, and an equipment diagram can be efficiently created without erroneous input.
[0013]
Also, When the three-way connection discriminating means 333 discriminates that it is a three-way connection, the switches SW1 and SW2 are displayed as symbols of the three-way switch. I did so Since the three-way switch symbol is displayed on the plan view, the equipment parts to be attached to the building unit can be easily determined based on the equipment drawing thus completed by simply looking at the equipment drawing.
[0014]
The CAD system for creating facility diagrams according to the present invention is a facility diagram showing facility parts and mutual connection of the facility parts on a plan view of a unit type building constructed by combining a plurality of box-shaped building units. Is a CAD system for creating an equipment diagram of a unit type building that supports the work of creating a lighting system, instructing the input of the illumination CL and the switches SW4 and SW5 on the plan view, and wirings L4, L5 and L6 for connecting them When the switch SW4 and the rising wiring L4 connected to the switch SW4 are input to the lower floor plan view by the equipment component input instructing means 331 and the equipment component input instructing means 331, the rising wiring L4 symbol is displayed. The virtual symbol display means 334 to be displayed on the upper floor plan and the equipment component input instruction means 331 provide the upper floor When the lighting CL and the falling wiring L6 connected to the lighting CL are input to the plan view, and the falling wiring L6 is connected to the rising wiring L4 symbol, the lighting CL and the lower floor input to the upper floor plan view are displayed. It is characterized by comprising upper and lower floor connection recognition means 335 for recognizing that the switch SW4 input in the plan view is connected.
[0015]
According to this configuration, when a three-way connection is made to a building having upper and lower floors, when the switch SW4 and the rising wiring L4 connected thereto are input on the lower floor plan by the equipment component input instruction means 331, the rising wiring is input. The L4 symbol is displayed on the upper floor plan.
Therefore, when inputting the illumination CL, the switch SW5 connected thereto and the falling wiring L6 to the upper floor plan, the falling wiring L6 is simply connected to the rising wiring L4 symbol displayed in the upper floor plan. be able to.
Then, when the falling line L6 is connected to the rising line L4 symbol, it is automatically connected that the illumination CL input to the upper floor plan and the switch SW4 input to the lower floor plan are connected. Since it is recognized, it is possible to automatically associate the upper and lower floor switches SW4 and SW5 with the illumination CL.
[0016]
In the above description, when the upper and lower floor connection recognition means 335 connects two switches SW4 and SW5 to one illumination device CL, it is preferable to display the switches SW4 and SW5 as symbols of a three-way switch.
In this way, for example, even if a single path switch is input by mistake at the beginning, when two or more switches SW4 and SW5 are connected to one lighting device CL, the switches SW4 and SW5 are connected. Since it is displayed as a three-way switch symbol, it is possible to eliminate mistakes in equipment parts attached to the building unit.
[0017]
Moreover, it is preferable to provide a numbering means for assigning a number to the rising wiring input by the equipment component input instruction means.
In this way, even when there are a plurality of rising wirings, it is possible to connect with few errors.
[0018]

[0025]
Next, the operation of this embodiment will be described using a specific example of the design of a unit type building.
In order to create an equipment drawing of a unit type building with the CAD system 1 described above, first, a plan view showing the layout of the building unit and the layout of the room is created, and a switch, lighting device, electrical outlet, Equipment parts such as wiring to be connected are arranged.
Specifically, when (1) outer wall input work, (2) partition wall input, and (3) indoor part input work are completed, the floor plan of the unit type building is completed, and the equipment part input work can be performed on this. Become. That is, it is possible to arrange facility parts such as switches, electrical outlets, and lighting devices on this plan view, and to create an facility diagram that represents electrical wiring that connects these facility parts to each other.
[0026]
Therefore, as an example, specific arrangement and connection of equipment parts when performing the three-way connection will be described.
First, as shown in FIG. 3, the grid intersection G1 of the grid module core 43 serving as the center line of the single grid wall 71 in the created plan view and the grid module core 43 on which the double grid wall 72 is disposed. A case where a switch is arranged at the grid intersection G2 will be described.
[0027]
First, the cursor K is moved to the inside of the building unit 70, and the building unit 70 is designated. Then, grid module core lines 43 in both the vertical and horizontal directions are displayed inside the designated building unit 70. In this state, the above-described equipment component selection means 332 selects a switch as an equipment component to be input.
Next, when the cursor K is moved on the grid intersection G1 of the grid module core line 43 and the selected switch is arranged, the switch SW1 is displayed as shown in the enlarged view of FIG.
Similarly, the cursor K is moved onto the grid intersection point G2, and the selected switch is arranged.
[0028]
Next, a description will be given of a case where lighting devices that are turned on and off by the switches SW1 and SW2 that are arranged as described above are arranged and the switches SW1 and SW2 are connected to the lighting devices.
After the input of the switches SW1 and SW2 is completed, the lighting equipment is selected / input by the equipment component selection means 332, and the grid intersection G3 in the room surrounded by the single grid wall 71 and the double grid wall 72 as shown in FIG. The cursor K is moved over to select the grid intersection point G3.
When the grid intersection point G3 is selected and determined, the illumination device CL is displayed at the grid intersection point G3 as shown in FIG.
[0029]
Here, the equipment parts selection means 332 and the equipment parts input instruction means 331 select and input the wirings L1 and L2 that connect the switches SW1 and SW2 and the lighting equipment CL, and connect them.
Then, the three-way connection determining unit 333 detects that the two switches SW1 and SW2 are connected to one lighting device CL, and determines that the three-way connection is established. Thereby, each switch SW1, SW2 is displayed as a symbol of a three-way switch.
As shown in FIG. 7, the three-way connection determining means 333 does not determine the three-way connection only by connecting one switch SW1 to one lighting device CL. Therefore, the switches SW1, SW2 are not determined. Is displayed as a symbol of a single path switch.
[0030]
Next, a case will be described in which a three-way connection switch and a lighting device are arranged on an upper and lower floor plan view provided with a staircase.
First, as shown in FIG. 8, the switch SW4 is input by the above-described operation to the grid intersection G4 in the vicinity of the staircase 73 in the lower floor plan view, and then the rising wiring L4 connected to the switch SW4 is input. At this time, when a plurality of rising wirings are input to the lower floor plan, the equipment component input instructing means 331 can number them. Here, the equipment component input instruction unit 331 also serves as a numbering unit.
[0031]
When the rising wiring L4 is input to the lower floor plan, the virtual symbol display means 334 changes the switch SW4 and the rising wiring L4 symbol input to the lower floor plan to the upper floor plan as shown in FIG. Is displayed (represented by a broken line in FIG. 9).
Here, the switch SW5 is input to the grid intersection G5 in the vicinity of the staircase 73 in the upper floor plan view, and the illumination device CL is input to the grid intersection G6, and the wiring L5 that connects them is input to connect them. Subsequently, the falling wiring L6 connected to the illumination device CL is input, and the falling wiring L6 is connected to the rising wiring L4 symbol.
[0032]
Then, when the falling wire symbol L6 input to the upper floor plan is connected to the rising wiring L4 input to the lower floor plan, the upper and lower floor connection recognition means 335 is input to the upper floor plan. It is recognized that the lighting device CL is connected to the switch SW4 input to the lower floor plan. Thereby, the switches SW4 and SW5 on the upper and lower floors and the illumination device CL can be automatically associated and registered. Incidentally, the result may be output as a diagram as shown in FIG. 9, or may be output as associated data.
[0033]
In this way, on the plan view showing the layout of the unit type building and the arrangement of the indoor parts, the equipment diagram is completed representing the arrangement and connection of equipment parts such as switches, lighting equipment, and electrical outlets. Then, the factory determines the facility parts to be provided in each building unit 70 and the like based on the facility diagram completed in this way, and produces the building unit.
[0034]
According to this embodiment, there are the following effects.
That is, on the plan view, the lighting device CL and the switches SW1 and SW2 are instructed to input, and the facility component input instructing means 331 for instructing the input of the wirings L1 and L2 connecting them, and one lighting device CL. Since the three switch connection discriminating means 333 for discriminating that the three switches are connected when the two switches SW1 and SW2 are connected, the equipment component input instructing means 331 provides 2 to one illumination device CL. When two switches SW1 and SW2 are connected, it is determined that the switch is a three-way connection. Therefore, when the switches SW1 and SW2 are input, it is not determined whether the switch SW1 or SW2 is a three-way switch or a single-way switch. Also good. Therefore, the input burden on the operator can be reduced, and an equipment diagram can be efficiently created without erroneous input.
[0035]
At this time, if the three-way connection discriminating means 333 discriminates that it is a three-way connection, the switches SW1 and SW2 inputted on the plan view are displayed as symbols of the three-way switch. Based on the figure, the equipment parts to be attached to the building unit can be determined easily by simply looking at the equipment diagram.
[0036]
In addition to the above configuration, since the virtual symbol display means 334 and the upper and lower floor connection recognition means 335 are provided, when a three-way connection is made to a building with upper and lower floors, the equipment part input instruction means 331 causes the lower floor to When the switch SW4 and the rising wiring L4 connected to the switch SW4 are input on the plan view, the rising wiring L4 symbol is displayed on the upper floor plan view. Therefore, when the lighting device CL, the switch SW5 connected thereto, and the falling wiring L6 are input to the upper floor plan, the falling wiring L6 is simply connected to the rising wiring L4 symbol displayed in the upper floor plan. Can be made.
In addition, when inputting a rising wiring by the equipment component input instruction means 331, it is possible to attach numbers to these. Even when there are multiple rising wires, there are few mistakes and you can connect them.
[0037]
When the falling line L6 is connected to the rising line L4 symbol, it is automatically connected that the lighting device CL input to the upper floor plan and the switch SW4 input to the lower floor plan are connected. Since it is recognized, the upper and lower floor switches SW4 and SW5 can be automatically associated with the lighting device CL. Accordingly, since no special association operation is required, the burden on the operator can be reduced, and the facility drawing can be efficiently created by reducing the input man-hours.
[0038]
Note that the present invention is not limited to the above-described embodiment, and includes the following modifications.
That is, in the above-described embodiment, the connection work of the switches SW1, SW2, SW4, SW5 and the lighting device CL is performed by the operator's input work. However, if the correspondence is clear, the connection work is automatically performed. By doing so, the operator's input man-hours can be significantly reduced.
In this case, when the wiring work is automated, if the input is arranged in the order of the first switch, the lighting device, and the second switch, the first switch and the lighting device, and the lighting device and the second switch can be automatically connected. What is necessary is just to comprise.
[0039]
8 and 9, the switches SW4 and SW5 are initially input as three-way switches. For example, when two switches are connected to one lighting device in the upper / lower floor connection recognition unit 335, If the function of displaying the switch as a symbol of a three-way switch is provided, it is not necessary to determine the type of switch from the beginning, and the burden on the operator can be reduced.
[0040]
Further, the CAD system 1 described above has been used for a production preparation system. However, the present invention is not limited to this, and even when used as a basic design system, the same effects as those described in the above-described embodiment can be enjoyed. Can do.
In addition, the specific structure and shape of the present invention may be other structures as long as the object of the present invention can be achieved.
[0041]
