2. Description of the Related Art Japanese Unexamined Patent Publication (Kokai) No. 5-233765 discloses a technique for supporting the process of selecting the type of lighting equipment. In this technique, a CAD operator inputs data on the size, height, and shape of a room and data on the reflectance of a ceiling, a wall, or a floor. The CAD operator also inputs the data of the attachment position of the device. Further, the CAD operator inputs the required illuminance. On the other hand, on the CAD side, data on the type of lighting equipment and data on the brightness of the lighting equipment are stored in advance.

Therefore, in the CAD system, in the room in which the CAD operator inputs the size, height, shape, and reflectance, an instrument of a type registered in advance is attached to an instrument attachment position designated by the CAD operator. As a result, the illuminance is calculated, and based on the calculation result, the type of the luminaire capable of realizing the illuminance input by the CAD operator is searched and displayed on the CAD operator. CA in this way
The D operator can know the types of fixtures that can be used, and the process of creating the lighting equipment drawing is supported.

[0005]

The above-mentioned prior art indicates the level of the current CAD system, and the CAD operator can determine not only the size and reflectance data of the room but also the mounting position of the luminaire and the required illuminance. Must also decide. Therefore, a CAD operator is required to have sufficient knowledge about lighting design, and the number of people who can use the CAD system is limited. The present invention realizes a CAD system capable of obtaining a lighting equipment design drawing capable of satisfying a certain standard even if a CAD operator has insufficient knowledge about lighting design.

[0006]

As shown schematically in FIG. 1, a lighting equipment drawing creation support apparatus according to the present invention includes means 2 for inputting a business condition of a building and attributes of a room, and an architectural drawing. Means for inputting, memorizing the illuminance normally required in the room having the attribute of the building of the business type and the type of the luminaire normally used in association with the attribute of the business type and room of the building Means 6, means 8 for inputting the illuminance of the room and the type of lighting equipment used in the room with reference to the standard data stored in the storage means 6, and realizing the illuminance of the room with the lighting equipment of that type A program 10 for calculating the number of lighting fixtures required to perform the calculation and a pattern for arranging the required number of lighting fixtures in the room, and a lighting equipment drawing in which the calculated patterns are displayed together on the architectural drawing. Output means 1 And each of the units 2,4,6,8,1
And a calculation means 14 for operating 0 and 12.

[0007]

According to this device, standard illuminance and equipment type data for the business conditions of the building and the attributes of the room are stored in advance, and the CAD operator actually designs the data while referring to these standard data. You can enter the data of the room you are in. For this reason, even if the CAD operator has insufficient knowledge about lighting design, at least standard lighting equipment design is performed, and a lighting equipment drawing that satisfies certain criteria can be obtained. Further, a person having knowledge of lighting design can make necessary corrections based on the standard data and can perform various designs.

[0008]

[Preferred Means and Actions for Solving the Problem] In the case of the above-mentioned support device, it is preferable that the grade of the lighting equipment can be designated, and standard data is stored for each grade. In this case, the standard data in the case of high grade is shown to the CAD operator for the high grade building, and the standard data in the case of low grade is shown to the CAD operator for the low grade building. Even if you do not have sufficient design knowledge, you can carry out various designs from high grade to low grade.

Further, when the required number of lighting equipments is R, a process for obtaining a combination of two integers that become R when multiplied, that is, Ra and Rb satisfying the equation of R = Ra × Rb is prepared. It is preferable. In this case, when arranging the required number of units in a matrix, the number of rows and the number of columns to be arranged are automatically specified, and a large room can be designed.

Further, when there are two or more sets of two integers for which the equation of R = Ra × Rb holds, selection is made using the distance between the corner of the room and the luminaire closest to the corner as an index. It is preferable that a process for determining a set of integers to be performed is prepared. In this case, it is possible to obtain a pattern in which the lighting fixtures are evenly distributed all over the room.

Further, after increasing the required number R by 1,
For example, if the number of vehicles required up to that time is 33, add 34
It is preferable to prepare a process of re-obtaining a set of two integers Ra and Rb that satisfy the formula of R = Ra × Rb after increasing the number to the base. In this case, an arrangement pattern that matches the room can be obtained, and a CAD operator who does not have sufficient knowledge can perform the same level of design as a skilled designer.

In addition, total floor area 44, number of floors 45, floor height by floor 46,
A floor area 47 for each floor, data 48 indicating whether the floor is a windowless floor, and the like are also stored corresponding to the building. These data are also input by the CAD operator for each building.

The facility construction name master 100 is stored in the storage device 28 in advance. This is for displaying a list of equipment construction names required for completion of the building, and is not necessary if the list of equipment construction names for displaying the list and the construction work required in relation to the business category. It also includes information indicating whether the equipment is installed properly. In the case of FIG. 4, a part of the equipment work name list shows the electric light equipment construction, the loudspeaker equipment construction, the television joint reception equipment construction, etc. For example, in the case of a warehouse, the loudspeaker equipment construction and the television joint reception equipment construction are unnecessary. Yes, it indicates that the lighting equipment construction is required.
This equipment construction name master 100 is a CAD program 29
Can be displayed on the color display 23 and the CAD operator can refer to the list. Further, for example, if the relationship between the business type and the equipment construction required for the business type changes with the change of the times, the memory in the master data can be updated. Since the operator can refer to this list and use it as a checklist, it is possible to grasp the number of required blueprints of the building equipment and use it as a material for process control in the design work.

As shown in FIG. 5, the architectural drawing information file 50 includes a subject code 31, a building code 32 and a floor number 5.
1 is a file in which architectural drawing information 52, paper size 53, and scale 54 are stored in association with each other, and data is written by the CAD program 29 executing the processing of FIG. FIG. 9 shows the processing contents executed by the architectural drawing information reading subroutine which is a part of the CAD program. First, in step S4, the architectural drawing information is read. When the architectural drawing itself is created by CAD for building and the architectural drawing information is stored in the floppy disk, the floppy disk is read by the floppy disk drive 26 and the architectural drawing information is read. Scanner 2 if architectural drawings are drawn on paper
5 reads the architectural drawing information. In this case, one floor of the building is input. Step S6 of FIG.
This is a step of inputting a subject code, a building code, a floor number, a paper size and a scale corresponding to the architectural drawing read in step S4, and in step S8, after these processing,
6 shows a process of writing data in the architectural drawing information file 50 shown in FIG. Note that any of before and after steps S4 and S6 may be performed. Here, the paper size and scale are
The operator inputs an optimum value for each drawing, and once this information is input, the operator sets particularly different data when the output means 14 outputs the architectural drawing based on this architectural drawing information. Unless it is done, the sheet of the size stored in the sheet size 53 is displayed at the scale stored in the scale 54.

As shown in FIG. 8, the building personality information file 80 includes a building code 32 indicating a building, data indicating whether or not a lighting grade 81 and outlets are densely arranged, and a telephone receiving port. It is a file that stores data indicating whether or not to arrange at high density in pairs, and
Data is input by the program 29 executing the building personality information input subroutine shown in FIG.

In step S12, the building code is input.
Next, in step S14, data indicating the character of the building is input. First, the lighting grade indicates the grade of a lighting fixture used in a building, and can be set between grades 1 to 3. Grade 3 is used when the character of the building is high grade and high-grade lighting equipment is used,
Grade 1 is used for buildings with inexpensive lighting fixtures and Grade 2 is used for buildings with intermediate character. Regarding the number of outlets, the CAD operator is set to "more" for a building that requires a larger number and "less" for a building that requires a smaller number. The same applies to telephone receptacles, high / low tensions, and speakers. For example, in a building with a high noise level or a building in which background music is desired to be played, "large" is set for the speaker. Now, the above processing, that is, input to the subject file 30 of FIG. 3, input to the building information file 40 of FIG. 4, input to the architectural drawing information file 50 of FIG. 5, and input to the building personality information file 80 of FIG. This completes the data input required for building equipment design.

Next, as a process for designing a building facility, a case of first designing a light facility will be described. 11 is CA
The processing procedure performed when the D program 29 executes the illumination equipment drawing creation support subroutine is shown.
First, in step S22, the subject code, building code, and floor number of the building to be designed are input. As a result, which floor of which building is to be designed is specified, and the architectural drawing information corresponding thereto is read from the architectural drawing information file 50 and displayed on the color display 23 (step S24). FIG. 12 illustrates an example of the displayed architectural drawing, and is a plan view of a building including windows, walls, doors, and the like.

Next, the CAD operator designates a room unit on the display while looking at this architectural drawing. In this case, the room unit is designated by moving the cursor on the screen with the mouse 22 and designating two points which are diagonal to the room. In the example shown in FIG. 12, the position and size of the room 123 are specified by specifying points 121 and 122 with the mouse. When this processing is executed, the CAD program 29
On the side of, the frontage, depth and area of the designated room are calculated (step S28). Here, the frontage is the length of the long side, and the depth is the length of the short side. After designating the room unit, the CAD operator inputs the number and attribute of the room (S26). The attribute entered here means the purpose of the room, and it is not necessary to consider the business condition of the entire building. Even in the same corridor, the preferable lighting conditions differ between the corridor of the hotel, the corridor of the office building, and the corridor of the school, but in the case of this support device, it is necessary to simply enter the attributes of the room or enter the business type of each building. Has been lost.

Next, step S30 is executed. Here, the building information file 40 is searched by using the building code input in step S22 as a key, and the business category of the building is read. Further, the building personality information file 80 is searched using the building code as a key and the grade and personality data of the building is read.

After the business type of the building, the attribute of the room, and the character of the building are specified by the above processing, the corresponding room master is specified and displayed on the color display 23. As shown in FIG. 6, the room master here stores the data of the building equipment normally required in the room of the attribute of the building of the category of the business, with the combination 61 of the category of the event and the key as the key. In addition, standard data that differs depending on the character of the building is stored.

In the case of FIG. 6, it is illustrated that the data of the building equipment normally required is different between the corridor of the hotel and the corridor of the office building. It also shows that even in the corridor of the same hotel, the standard data varies depending on the building grade. For example, in the case of a hotel corridor, which is a grade 3 hotel corridor, it is shown that a downlight embedded cover type luminaire is typically used. In the case of Grade 2, it is an embedded open type of downlight, and in the case of Grade 1, it is an embedded open type of fluorescent lamp. In the same corridor, if it is the corridor of an office building, Grade 3 will be standard with fluorescent lamp-embedded opalescent acrylate, Grade 2 will be standard with fluorescent lamp-embedded underside open type, and Grade 1 will be standard V type. It shows that it becomes.

[0026] In the case of the hotel corridor, in the number of outlet is common type is that the standard be placed one per 40m ^2, 1 per 60m ² in the small type is standard, the corridor it is a office building In the case of, it is 50 in many types
One per m ² is the standard and one per 70 m ² is standard for the few types. Below, standard data regarding telephone piping equipment, loudspeaker equipment, and automatic fire alarm equipment is stored, with the combination 61 of business type and attributes as a key.

In step S32 of FIG. 11, the room master is searched using the business type and attribute as keys, and the corresponding room master is displayed on the display 23. At this time, the personality data of the building is referenced, the corresponding grade column and the "more" and "less" columns are highlighted, and the equipment that should be placed in that room based on the common personality of the building The type and the number of items are displayed in a list on the CAD operator.

In step S34 of FIG. 11, the CAD operator determines the room information file 70. Ie CA
The D operator inputs the data of the room information file shown in FIG. 7 while referring to the standard data displayed on the display 23. In FIG. 7, the equipment code indicates the type of lighting equipment. As described above, standard equipment types are registered in the room master in advance based on the business type, attributes, and personality, and displayed on the CAD operator. Therefore, if the standard data is acceptable, the CAD operator can click the standard data to input the intended data in the equipment code field of the room information file 70 in FIG. 7. If the CAD operator determines that the standard data is not suitable, the CAD operator enters the code of the instrument as deemed appropriate. In this way, even a CAD operator who does not have sufficient design knowledge can perform a standard design, and a CAD operator who has sufficient design knowledge should design using this knowledge. Is possible. In the above example, even in the case of standard data, the CAD operator clicks on the mouse to input the data, but if the CAD operator does not operate anything, the standard data is set (input). A CAD program may be created.

The design illuminance in FIG. 7 is data indicating the illuminance required for the room being designed, and initial values are given to the business conditions of the building and the attributes of the room. CAD operators
The design illuminance can be made brighter or darker than the initial value. The work surface height indicates the height at which the design illuminance is realized, and the initial value is also given to the business condition of the building and the attribute of the room. For example, the work surface height is 0 m (floor surface) in a corridor, and 0.85 m (office desk height) is set as an initial value in an office room. The reflectivity indicates the reflectivity of the ceiling, walls and floor of the room, which is also given an initial value for the business category and attributes. This value is also CAD
The value of the reflectance can be increased or decreased according to the actual situation, which can be changed by the operator, for example, in a room in which it is known that a carpet having a color tone darker than the standard is used. As for the speaker position of the loudspeaker, the CAD operator inputs either the wall or the ceiling based on the standard data of the room master 60. The CAD operator also inputs the presence / absence of an attenuator. Regarding the number of loudspeakers of outlet equipment, telephone piping equipment, and loudspeaker equipment, based on the standard number registered in the room master 60 (the standard number and standard instrument type when the standard number and standard instrument type differ depending on the personality) CAD operator inputs. Also in this case, when the displayed standard data is acceptable, CA
It is also possible to eliminate the operation of the D operator.

Based on the building information file shown in FIG. 4, the automatic fire alarm system determines whether or not the floor to which the designed room belongs is a windowless floor, and either the windowed window or the windowless window is highlighted. Light display. Also, the type of sensor required by law is selected depending on whether or not the floor is a windowless floor. In this way, in step S34 of FIG. 11, the work of determining the room information file 70 shown in FIG. 7 is performed.

When the CAD operator finishes inputting the above information, the CPU 20 causes the CPU 20 to execute the step S36 in FIG.
The process of S38 is executed. Step S36 is realized by executing an illuminance calculation program and a program for calculating the required number of units by the illuminance calculation program. Further, step S38 is realized by a program for calculating a pattern for uniformly arranging the calculated required number in the room whose dimensions are specified. The contents of this processing will be described with reference to FIGS. 13 and 14. As shown in FIG. 13, the frontage (a), depth (b), and area (c
= A × b) and the ceiling height (d) are specified. Next, the equipment code, design illuminance, work surface height, reflectance, and hanger length are specified. Here, data other than the length of the hanger has already been entered. A value registered in advance for each equipment code is used as the lifting tool length. Next, the CPU 20 calculates the light source height (j) from the ceiling height (d), the work surface height (g), and the hanger length (i). Also, from the frontage, depth, and light source height, the room index (k)
To calculate.

Next, the CPU 20 concretely specifies the device belonging to the device code. Here, the concrete instruments are ranked in advance. For example, when the instrument type is a fluorescent lamp-embedded lower surface open type, the rapid start straight tube white type 40 W, one-lamp instrument is registered in the ranking 1. . Rank 2 has 40W, two-lamp fixtures registered. FIG.
Is programmed to be repeatedly executed. When the CPU 20 first executes the processing, the equipment of rank 1 is specified, and when it is executed the second time, the equipment of rank 2 is specified. At this time, the CAD operator can change the equipment by selecting the light source type (fluorescent lamp, incandescent lamp, etc.), lamp type (rapid start straight tube white type, etc.), wattage, and lamp number.

Next, the CPU 20 calculates the illumination rate from the reflectance, the room index and the device. In addition, the maintenance rate is determined from the type of equipment. Then, based on the design illuminance, the area, the luminous flux of the lamp, the illumination rate, the maintenance rate, and the number of lamps, the number (R) of the lighting fixtures necessary for the room is calculated. Note that the calculation process of FIG. 13 is an average illuminance calculation by the ordinary light flux method, and since the details are described in the text of the light flux method, a detailed description will be omitted.

Next, FIG. 14 shows a process of calculating a pattern for arranging a required number of units in a room. (1) First, the CPU 20 sets a standard placement method. C
The PU 20 sets the distance between the appliances to 2 when the distance between the appliances and the wall is 1. The CAD operator can change the value of "2". The CAD operator can also select an arrangement method such as even arrangement, zigzag arrangement, system ceiling, and connection. (2) Next, the CPU 20 sets a standard arrangement direction. C
PU20 arranges the fluorescent lamp in the vertical direction in the front (long side),
As an exception, if the depth (short side) is less than the length of the fluorescent lamp fixture, place the fluorescent lamp parallel to the long side. Further, the CAD operator can change the arrangement direction set by the CPU 20. Note that this process is not executed in the case of downlight.

(3) Next, the maximum value (S) of the number of fluorescent lamps that can be arranged in the room in the longitudinal direction is calculated. That is, the depth (b) is divided by the instrument length to obtain the maximum value. At this time, the fractional part is truncated. (4) Next, when the number of arrangements in the frontage direction is Ra and the number of arrangements in the depth direction is Rb, Ra × Rb = R (required number)
And Rb ≦ S (maximum number that can be arranged in the depth direction)
Ra and Rb satisfying the relationship of are calculated. When there are a plurality of combinations of Ra and Rb (for example, 1 × 18, 2 × 9, 3 ×
6,6 × 3,9 × 2,18 × 1), all sets are obtained. And for all of the obtained Ra and Rb pairs,
Using the value input in (1), find the pair of Ra and Rb that minimizes L. Where L is the length from the corner of the room to the center of the luminaire closest to that corner.

(5) Next, among the combinations of Ra and Rb, L
Is the smallest L (LMIN)
Is compared with a predetermined value. When the value is above the specified value, the illuminance may become dark near the corner of the room, so increase the required number by one and repeat (4). While the process is repeated, the values of Ra and Rb at which LMIN becomes a predetermined value or less are obtained. (6) Next, based on Ra and a (frontage), the device interval is calculated. Then, it is assumed that a rational arrangement pattern is obtained when the device interval becomes equal to or larger than a predetermined value. On the other hand, when the device interval becomes equal to or smaller than the predetermined value, the number of lights per device is increased.
This corresponds to shifting from rank 1 to rank 2 appliances in FIG. 13 (5). After changing the appliances in this way, the processing after (6) in FIG. 13 is repeated again to determine the optimum appliances, the number of them, and the optimum arrangement pattern. In this way, the processes of steps S36 and S38 of FIG. 11 are executed. After the appliance type, the number of appliances, and the arrangement pattern are determined in this manner, the CPU 20 calculates the illuminance and stores the data in the room information file 70.

The above process is repeated for all rooms. Data transfer processing prepared in the CAD program 29 is used for the same room and the same floor.
15 and 16 show an example of the arrangement pattern obtained by the above processing, 150 shows an example in which an allowance pattern is obtained when two fluorescent lamps are arranged, and 160 shows 1 An example in which an allowance pattern is obtained when a fluorescent lamp of a light type is arranged is shown. Even for rooms having the same shape, FIG. 15 or FIG. 16 may be obtained depending on the value of the design illuminance. Reference numeral 151 shows an example of arrangement in the corridor of the office building, and 161 shows an example when the corridor of the hotel is equipped with grades 3 or 2 (see the room master in FIG. 6).

In this way, according to this lighting equipment drawing creation support subroutine, the CAD operator refers to the standard data based on the business condition of the building, the attribute of the room, and the character of the building, and if necessary, You can use your own knowledge to set more desirable conditions and then proceed to create appropriate lighting equipment drawings for the room.

FIG. 17 shows an automatic fire alarm facility drawing creation support subroutine. The processing shown in the figure shows an example in the case where the room unit specification, the room number input, and the attribute input have been completed by another subroutine. If these inputs have not been completed yet, this subroutine Input is possible during execution. When the room unit designation, the room number assignment, and the attribute input are completed, the room to be designed is specified by steps S52, S54, and S56.

When the room to be designed is specified, in step S58, data indicating the business condition, building structure, and windowless floor of the building is read. The attributes of the room are also read. Then, the data of the corresponding room is read out from the room master 60, and the type of the sensor of the room is determined (S62). Next, the CPU 20 determines the arrangement based on the type (S64). This is repeated for all rooms.

In addition to the above, the CAD program 29 is provided with an outlet facility drawing creation support subroutine, a telephone piping facility drawing creation support subroutine, and a loudspeaker equipment drawing creation support subroutine, and the CAD operator uses these subroutines to relate to the above equipment. It is possible to create design drawings with high efficiency. The above-described embodiment can be applied to the design of air conditioning equipment.

[0042]

According to the present invention, the illuminance normally required for the business condition of the building and the attribute of the room and the type of the lighting equipment normally used are stored in advance. Since it is possible to input data while referring to the data, even if the CAD operator does not have sufficient knowledge about lighting design, it is possible to design lighting equipment at least at a standard level. Stable lighting equipment drawings that satisfy the requirements can be obtained.
