BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting design calculation control device and a lighting design calculation control device suitable for displaying a display based on a calculation result in a lighting design change in almost real time by enabling a processing time involved in lighting design to be increased. The present invention relates to a lighting control calculation control method.

2. Description of the Related Art Generally, when designing the arrangement of lighting fixtures to be installed inside a building, for example, a program for performing lighting design is used, and a computer or the like that performs various calculation processes based on the program is used. By using a system device and performing an input operation, a simulation is performed so as to obtain an optimum illuminance and uniformity (illuminance according to an irradiation area) according to conditions such as the type and arrangement of the lighting fixtures inside the building.

More specifically, if a lighting design program required for designing is capable of performing various lighting calculations in accordance with the types and arrangement conditions of lighting fixtures, a computer in a system device executes, based on the program, Various lighting calculations are performed according to the input conditions, and the calculation result is, for example, 2
Contour lines (also referred to as contours) are displayed in a dimension, and colors are displayed for each equal value. That is, an illuminance distribution diagram and a luminance distribution diagram inside the building based on the arrangement conditions and types of the lighting fixtures are displayed on the screen. As a result, the designer can recognize on the screen the illumination state in the type and arrangement condition of the lighting fixture in the design.

Also, when the lighting design program is a computer graphics program capable of calculating lighting so that it can be displayed in three dimensions, similarly, the computer uses contour lines and color-coded display to display lighting equipment inside the building. It is also possible to display an illuminance distribution diagram and a luminance distribution diagram based on the arrangement conditions and types.

Further, recently, as an application example of the above-mentioned lighting design technology, a necessary area for design is designated at the time of inputting data such as the type and arrangement state of a lighting fixture.
Illumination calculation programs capable of performing illumination calculations and obtaining the maximum, minimum, and average illuminance, or luminance and uniformity in an arbitrary area have been developed and put into practical use. FIG. 7 shows an example of such a lighting design calculation program.

FIG. 7 is a flowchart showing an example of a conventional illumination design calculation program.

In this example, as a system control device required to execute a lighting design calculation program, for example, a computer that performs processing based on a program capable of calculating lighting associated with lighting design, various characteristic diagrams based on calculation results, and the like. Means (monitor) capable of displaying data, and output means (printer) capable of outputting various drawings and the like based on calculation results as prints
Lighting design is performed using a lighting design calculation control system device constituted by input operation means for inputting data such as designation of an arbitrary area or change in arrangement of lighting equipment.

Now, assuming that the designer executes the lighting design calculation program shown in FIG. 7 using the lighting design calculation control system device having the above configuration, the computer starts operating based on the program. That is, the computer shifts the processing to step S10 and executes the program for designing the lighting, so that the screen for designing by the input operation of the designer is displayed on the screen of the monitor.

When data is supplied through the input operation means by the operation of the designer, step S1 is executed.
By the processing according to 0, based on the supplied data, the computer determines the internal configuration (shape and size of ceiling and wall, etc.) of the lighting equipment and the lighting equipment installed inside the building. The processing for designing the lighting such as the approximate installation location of is performed. Then, the computer shifts the processing to step S11.

Then, in the processing in step S11,
The shape data of the interior of the building in which various lighting fixtures are assumed to be installed and the shape data of the lighting fixture to be installed are input by the designer, and the computer inputs the building interior data designed in step S10 based on the input various shape data. And the change is stored in a predetermined memory. Then, the process proceeds to step S12, and in the process in step S12, the arrangement of the lighting fixture having the determined shape is determined by the input operation of the designer, so that it is necessary to perform the simulation of the lighting fixture. The input operation of the basic data ends.

The input operation of the shape data and the like in the lighting fixture is performed by, for example, the type of the lighting fixture and the brightness corresponding to the type, which are stored in a predetermined memory inside the computer in advance. By reading out data such as brightness according to the direction and arrangement of the image, the data may be obtained as data necessary for simulation.

After that, the computer shifts the processing to step S13, and performs the illumination calculation of the illuminance in the calculation area designated by the operation of the designer or in the calculation area of the entire installation facility area. In other words, the designer specifies the area where the lighting fixture simulation is to be performed, and performs the lighting calculation using the specified area as the calculation area, thereby maximizing the illuminance in the specified calculation area.
Obtain the calculation results of minimum, average and uniformity.

After that, in the process in step S14, the calculated result is output to the display means or the output means. Thus, an illuminance distribution map, a luminance distribution map, and the like in the designated area are displayed on the screen of the display unit. In this way, the designer can confirm the irradiation state based on the arrangement condition and shape of the lighting fixture designed in advance.

After confirming the simulated display screen as described above, the designer next looks at the display screen and changes the arrangement of the lighting equipment or adds or removes the lighting equipment in order to obtain a more optimal illumination state. Perform operations based on changes, such as deletion.

In this case, the computer goes to step S15
In the process according to the above, it is detected whether or not a request for changing the arrangement of the lighting equipment is made by the designer. If the arrangement is not changed, the process proceeds to step S16. If the arrangement is changed, the process is performed in step S12. After the arrangement of the lighting equipment is newly changed, the same processing is performed thereafter.

On the other hand, when the arrangement of the lighting equipment is not changed, the computer causes the output means to output the calculation result already calculated in step S13, and prints out the illuminance distribution map and the luminance distribution map in the designated area. Works. Thereafter, the computer determines that the work related to the lighting design has been completed, and ends the control based on the program.

The above-described lighting calculation process is performed on the assumption that a plurality of lighting fixtures (light sources having openings) are provided, for example. FIG. 8 shows the basic principle of the illumination calculation in this case. That is,
As shown in FIG. 8, the illuminance (Etotal) of a certain surface illuminated by a plurality of light sources (light source 1 and light source 2) can be obtained by adding the illuminance of each light source. Therefore, the illuminance (Etotal) of a certain surface is expressed as Etotal = E1 + E2. By performing the illumination calculation based on such a principle of the illumination calculation, a calculation result corresponding to a plurality of lighting fixtures can be obtained. Become.

However, conventional computer graphics and other lighting design calculation programs use only a storage area for storing only the lighting calculation results calculated as described above, that is, only the lighting calculation results. Is controlled to be stored. For this reason, if an input operation such as deleting or adding only one of the plurality of light sources or changing the irradiation direction in the lighting fixture is performed after the lighting calculation process, the change after the change is performed. A new lighting calculation (relighting calculation) must be performed based on all input conditions of
In order to perform display based on the lighting settlement result after the change, it is necessary to return the process to the lighting calculation process (steps S12 and S13) again to obtain the lighting calculation result every time the lighting fixture is changed.

For example, as shown in FIG. 9 as an example of a lighting design in a lighting installation facility, a lighting design in a stadium as shown in FIG. 9 may be performed. The arrows shown in the figure indicate the direction of illumination from the light source, the illuminance level, and the like, and the starting point (root) of the arrow indicates the position of the light source.

In order to secure the optimum illuminance required for the execution of the competition in the stadium, it is necessary to arrange a plurality of lighting devices (light sources) of several hundreds in the stadium.
Therefore, when designing the lighting of a stadium having such a large number of lighting fixtures, the designer looks at a display (for example, an illuminance distribution map in the ground) based on the lighting calculation result obtained by the lighting calculation process. In addition, a change operation for performing change adjustment (also referred to as aiming adjustment) of the irradiation direction in each light source is indispensable. For this reason, since the input operation accompanying such aiming adjustment needs to be repeatedly performed, in the conventional illumination design calculation program, the illumination calculation process (relighting calculation process) must be performed from the beginning for each input operation.

For these reasons, when changing the lighting design, there is a disadvantage that an enormous amount of processing time is required, especially when the lighting design is performed for a facility having a large number of lighting fixtures. In general, when performing simulation of lighting, it is desirable to be able to perform simulation in almost real time when conditions for lighting fixtures are re-input for change, but as described above, a conventional lighting design calculation program and The lighting design calculation control device also has a problem that simulation at the time of change cannot be performed in real time.

[0022]

As described above, in the conventional lighting design calculation method and the lighting design calculation control device using the same, the display based on the calculation results of a plurality of lighting fixtures obtained from the lighting calculation results is viewed. However, if you want to perform a change operation such as a change in the arrangement of lighting fixtures or aiming adjustment and perform a simulation, it is necessary to perform relighting calculation processing based on all input conditions for each change operation.
As a result, there is an inconvenience that the processing time associated with the lighting design increases. For this reason, there was a problem that a lighting calculation result in accordance with a change operation such as a change in the arrangement of a lighting fixture or an aiming adjustment could not be obtained immediately, and a simulation could not be performed in real time.
The present invention has been made in view of the above-described problems, and individually stores a calculation result for each lighting fixture, and enables a lighting calculation process according to a design change using each calculation result. Without performing lighting calculations for each change operation,
An object of the present invention is to provide a lighting design calculation control method and a lighting design calculation control device that can perform lighting calculation processing at high speed and can display a display based on a lighting calculation result when a design is changed in almost real time.

First, a lighting design calculation control device configured as a system for executing a lighting design calculation control method according to the present invention will be described in detail with reference to FIG.

As shown in FIG. 1, the system device for executing the lighting design calculation control method according to the present invention includes a control unit 3 for controlling various processes associated with lighting design based on a lighting design calculation program. A lighting design calculation control device 1, input means 2 for performing an operation for inputting data necessary for simulation based on the lighting design calculation program, and a screen and lighting calculation results necessary for lighting simulation. A display unit 8 for displaying a characteristic diagram such as a display based on the screen on the screen, and an output unit 9 capable of printing out and outputting an illuminance distribution diagram and a luminance distribution diagram obtained from a result of the illumination calculation. I have.

The control unit 3 of the lighting design calculation control device 1 includes:
Input means 2 is connected. For example, when the input means 2 uses a key operation unit 2a capable of supplying input data associated with lighting design to the control unit 3 by key operation to the control unit 3 and a monitor screen serving as the display means 8 as an operation screen, A mouse operation unit 2b capable of operating input data associated with lighting design while looking at the screen.

For example, it is possible to change and specify a calculation area on a screen based on the result of lighting calculation, and to input data in accordance with the lighting equipment.

The display means 8 is, for example, a monitor, and displays a calculation result obtained by performing a lighting calculation process on the basis of the shape and direction of the ceiling and wall surfaces in the designed building and the respective lighting fixtures arranged thereon. Enable. That is, a screen (for example, an illuminance distribution diagram or a luminance distribution diagram) simulated by the illumination design is displayed. Thus, the designer can immediately recognize the information obtained by the simulation by looking at the display screen, and by using the screen as the operation screen, the mouse operation unit 4b while watching the screen based on the illumination calculation result.

Is also possible.

More specifically, the control unit 2 reads out data from the data storage unit 4 shown in the figure and illuminates it based on signals supplied via the connected key operation unit 2a and mouse operation unit 2b. Illumination calculation processing by the calculation unit 5, storage / readout of calculation results in the storage unit 6, and result display unit 7
To control the supply of data to

At the start of lighting design, the control unit 3 first displays a screen for performing lighting simulation based on a lighting design program. Thereafter, the shapes of the plurality of lighting fixtures to be provided are supplied to the control unit 3 by the operation of the key operation unit 4a or the mouse operation unit 4b by the designer. The control unit 3 performs, based on the supplied input data,
Data to be given to the lighting calculation unit 5 is read in advance from the data storage unit 4 in which lighting data (brightness) according to the lighting equipment, the illumination direction of the lighting equipment, the arrangement state, and the like are stored for each equipment. Control to give. This allows
Even in the case of performing simulations on a plurality of lighting fixtures, it is possible to obtain data necessary for performing the lighting calculation process.

The lighting calculation unit 5 performs a lighting calculation process based on the input data from the data storage unit 4 and outputs a lighting calculation result. At this time, when a plurality of lighting fixtures (light sources) are provided, the lighting calculation unit 5 performs lighting calculation processing for each light source based on data supplied for each lighting fixture (light source), and performs lighting calculation processing for each light source. Output the lighting calculation result. As a result, it is possible to obtain a lighting calculation result for each lighting fixture necessary for performing a simulation at the time of a design change.

By the way, in the lighting design calculation control device 1 of the present invention, unlike the prior art in which only the final lighting calculation result is stored, the amount of lighting calculation processing accompanying the design change is reduced to shorten the processing time. For this purpose, a storage means 6 capable of creating a storage area for storing calculation results for each of a plurality of lighting fixtures is provided.

The storage means 6 comprises, for example, a memory.
The memory has a number of storage areas corresponding to the number of light sources to be simulated under the control of the control unit 3. That is, the control unit 3 controls the memory 6 to create storage areas of a number corresponding to the number of light sources and to store the illumination calculation results for each light source calculated by the illumination calculation unit 5 in these storage areas. . The memory may be configured as an auxiliary storage device such as a hard disk, for example, in addition to the main memory of the computer inserted in the control device.

When the design is changed, the control unit 3 reads out the data corresponding to the light source to be changed from the data storage unit 4 and gives it to the illumination calculation unit 5 so that the change data of only the light source concerned is obtained. Perform lighting calculation processing. afterwards,
Control is performed so that the obtained illumination calculation result is rewritten in the storage area corresponding to the light source created in advance. Accordingly, various simulation patterns can be considered at the time of design change. In such a case, the illumination calculation process in the illumination calculation unit 5 is controlled so as to add or subtract individual illumination calculation results for each light source. It is possible to obtain a lighting calculation result accompanying a design change, and to reduce the processing time of the entire lighting calculation process.

More specifically, as shown in FIG. 3, a light source for temporarily performing a simulation (illustrated as a lighting fixture in the figure)
If there are n light sources 1, light source 2, light source 3,..., N light sources, the control unit 3 controls the memory area A, the memory area B, and the memory area so as to correspond to the number of light sources as shown in FIG. C,... Each storage area of the memory area n is created, and the illumination calculation result calculated for each light source is stored in the corresponding storage area. In this case, the illumination calculation result obtained for each light source differs depending on the arrangement position (arrangement location) as shown in FIG. That is,
The control unit 3 stores the calculation result for each light source obtained according to the arrangement position of the light source in the corresponding storage area. Thereafter, when the design is changed, assuming that the light source for which the aiming adjustment is performed is the light source 1 as indicated by an arrow in the figure, the control unit 3 determines only the data in the corresponding storage area A, that is, the data in the area surrounded by the oblique lines. Is controlled again so that the lighting calculation processing is performed again.

Therefore, as described above, the illumination calculation for each light source is performed in advance and stored in the corresponding storage area, so that one of the plurality of light sources is deleted or added at the time of design change. Or, even if a change operation such as aiming adjustment to change the irradiation direction is performed, the illumination calculation based on all the input conditions is not performed every time the change operation is performed, and the illumination calculation is performed only for the light source whose design has been changed. It is possible to obtain an illumination calculation result necessary for a simulation at the time of design change.

On the other hand, the control unit 3 reads out the calculation result for each light source initially calculated by the designer at the time of the basic design from the storage means 6 and also adds the obtained addition illumination result to the result display unit 7. Supply. At this time, when a design change such as an aiming adjustment is made, an added illumination result of the re-illumination calculation result of the aiming-adjusted light source and the illumination calculation result of another light source is supplied to the result display unit 7.

The result display section 7 performs a conversion process for displaying the supplied illumination calculation result on the screen of the display means 8 as, for example, an image, thereby generating RGB signals and displaying the result. Output to As a result, on the screen of the display means 8 (monitor), as shown in FIG. 4 or 5, for example, a system module diagram and an illuminance distribution corresponding to the arrangement position, shape, and the like of the lighting fixtures arranged in the building. An equal illuminance curve such as a diagram or a luminance distribution diagram can be displayed or displayed in different colors.

Next, the control operation based on the lighting design calculation control method of the present invention shown in FIG. 2 will be described in detail.

Now, assuming that the designer executes the lighting design calculation program shown in FIG. 2 using the lighting design calculation control device shown in FIG. 1, the control unit 3 starts operation based on the program. That is, the control unit 3 performs the processing in step S1.
When the program shifts to 0 and executes a program for performing lighting design, a screen for designing by a designer's operation is displayed on the screen of the display unit 8.

The operation unit 2 is operated by the designer.
When the data is supplied through the control unit 3, the control unit 3 performs the processing in step S <b> 10 based on the supplied data, based on the supplied data, the internal configuration (shape and size of the ceiling and wall surface, etc.) And the like, and a process for designing the lighting of the approximate location of the lighting fixtures installed inside the building. And the control part 3 transfers a process to step S11.

Thereafter, in the processing in step S11,
The shape data of the interior of the building in which various lighting fixtures are assumed to be placed and the shape data of the lighting fixtures to be placed are input by the designer, and the control unit 3 sets the building designed in step S10 based on the input various shape data. The internal data is changed and stored in a predetermined memory. Then, the process proceeds to step S50, and the process proceeds to step S50.
In the process by 50, the arrangement of the lighting fixture having the determined shape is determined by the input operation of the designer, and the input operation of the basic data necessary for performing the simulation of the lighting fixture is completed. When a simulation is to be performed using a plurality of patterns, data such as the shape and arrangement of the lighting fixture is input for each pattern.

Thereafter, the control section 3 shifts the processing to step S51. In the processing in step S51, the control unit 3 reads out the data of the lighting fixture based on the operation signal from the data storage unit 4 and supplies the data to the lighting calculation unit 5, so that the lighting calculation processing for each lighting fixture is performed. Obtain lighting calculation results for each fixture. At the same time, the control unit 3 generates a number of storage areas in the memory 6 according to the number of lighting fixtures (the number of light sources), and stores the lighting calculation results for the lighting fixtures calculated by the lighting calculation unit 5 in these storage areas. To control. After that, the control unit 3 proceeds to the process in step S52, and supplies the lighting calculation result read out from each storage area of the memory 6 and added to the result display unit 7, so that the display based on the lighting calculation result is performed. Display means 8 (monitor)
Will be displayed on the screen. As a result, a display using computer graphics as shown in FIG. 4 or an illuminance distribution diagram (iso-illuminance curve) as shown in FIG. 5 can be displayed.

On the other hand, if there is a design change, the designer performs an operation based on the design change by operating the mouse operation unit 2b while looking at the screen based on the displayed lighting calculation result. At this time, the screen based on the lighting calculation result
Assuming that the screen is a computer graphic screen shown in FIG. 4A, the designer adjusts the aiming adjustment (irradiation direction is shown in FIG. 4A) by using the mouse operation unit 2b to move the pointer x indicated by the hand shape in the figure. (Indicated by arrow A). Then, for example, aiming adjustment by the pointer x is performed as shown in FIG.
If the position is changed to the position shown in (b), the control unit 3 shifts the processing to step S54, and in this processing, the lighting calculation of only the light source 10 (see FIG. 5) indicated by the arrow A whose aim has been adjusted is performed. While controlling the lighting calculation unit 5 to perform
Control is performed so that data in the storage area corresponding to the light source 10 is rewritten. Even when a change such as deletion or addition of any one of the plurality of light sources is made, the illumination calculation of only the changed light source is similarly performed, and the data in the corresponding storage area is rewritten. To control.

In this process, when it is desired to simulate the addition or subtraction of a predetermined pattern by using a plurality of patterns, each data is read from the storage area of the corresponding light source and the data is interposed between these data. By performing addition or subtraction, an illumination calculation result necessary to display the simulation result after the design change is obtained.

Thereafter, the control unit 3 calculates the illumination calculation result of the light source 10 whose aim has been adjusted and the light source 11 which has been calculated previously.
By supplying the result of addition to the result of illumination calculation to the result display unit 7, the screen 9a of the monitor 9 is displayed on the screen 9a of FIG.
As shown in (b), a computer graphic image in which the density of the brightness after the aiming adjustment can be recognized at a glance can be immediately displayed. Further, by displaying the equal illuminance curve as shown in FIG. 5, the control unit 3 can also instantaneously recognize the change level of the illuminance in the computer graphic image before and after the aiming adjustment.

In FIG. 4, the shading of the illuminance in the illumination is shown in a hatched form, and the shading of the illuminance is described such that the darker the hatching width is, the darker the hatching is, and the wider the hatching, the brighter the brightness.

After the design change, the control section 3 returns the processing to step S53 again, determines whether or not to newly perform a design change, and if not changed, the processing in step S16 as described above. Displays an image based on the final lighting calculation result, and prints a computer graphic screen shown on the screen, for example, as shown in FIG. 4, or a characteristic diagram such as an iso-illuminance curve shown in FIG. 5 using a printer. Then, the execution of the lighting design calculation program is terminated.

Therefore, according to the present embodiment, even if the design is changed by the above-described lighting design calculation control routine, the lighting calculation processing based on all the input conditions is not performed every time the change operation is performed. It is possible to obtain an illumination calculation result necessary for a simulation at the time of design change only by performing an illumination calculation with only the changed light source.
Thus, the speed of the illumination calculation process based on the design change can be increased, and an effect that the simulation accompanying the design change can be performed almost in real time is obtained.

By the way, in the lighting design calculation control method and the lighting design calculation control device of the present invention, for example, a change in a simulation image due to a design change can be displayed as an image based on the RGB signals. Such an embodiment will be described in detail with reference to FIG.

In this embodiment, similarly to the above-described embodiment, the lighting calculation processing for obtaining only the data of the lighting fixture whose design is to be changed is performed and stored in the corresponding storage area. When synthesizing the image, the data of the changed lighting fixture and the data of the lighting fixture already calculated are added and supplied to the result display unit 7. When performing image subtraction, subtraction is performed between these data, and the obtained subtraction result is similarly supplied to the result display unit 7. The result display unit 7 displays data based on the addition result or the original result,
That is, the illuminance data is converted into RGB signals composed of luminance levels of 1 to 255 gradations based on the brightness, and is output to the monitor 9.

Thus, the changed simulation image is immediately displayed on the screen of the monitor 9.

An actual image is a simulation image as shown in FIG. In the image shown in FIG. 6 as well, the shading in the illuminance is shown in a hatched manner as in FIG.
Conversely, it is assumed that the lightness and darkness of the illuminance are described so as to be brighter as the width becomes wider.

For example, as shown in FIG. 6, a lighting fixture 20 such as a fluorescent lamp is placed at a predetermined position on the ceiling of a building as office lighting.
And a plurality of spot luminaires 21 such as downlights for effectively illuminating the floor or desk surface are designed to be respectively disposed. First, a lighting calculation process is performed for each lighting fixture. This makes it possible to obtain, for example, a data group for each lighting fixture with only a fluorescent lamp and a data group for each lighting fixture with only a downlight for each fixture type.

At this time, for example, the result of the lighting calculation in the lighting fixture using only the fluorescent lamp is displayed on the monitor 9 via the result display unit 7.
, The image shown in FIG. 6A can be displayed on the screen 9 a of the monitor 9. In addition, the same processing is performed on the result of lighting calculation in a spot lighting device including only downlights, so that a screen 9a of
The image shown in (b) can be displayed.

Now, the image shown in FIG. 6B is displayed.
It is assumed that the designer simulates a composite image with the image shown in FIG. In this case, the control unit 3 adds the lighting calculation result read from the storage memory corresponding to the plurality of lighting fixtures 20 and the lighting calculation result read from the storage memory corresponding to the plurality of spot lighting fixtures 21, and adds the results. The result of the illumination calculation is given to the result display unit 7. As a result, as shown in FIG. 6C, on the screen 9a of the monitor 9, it is possible to immediately display a combined image in which the irradiation states of the fluorescent lamp 20 and the downlight 21 are combined.

On the other hand, when it is desired to simulate changing the synthesized image to an image of one of the lighting fixtures, it is possible to perform a subtraction process. Therefore, even when the design is changed while displaying the image based on the R, G, and B signals, the lighting calculation processing associated with the design change can be performed at a high speed simply by adding or subtracting the light. Thus, it is possible to display a simulation image accompanying the design change.

In the embodiment according to the present invention, a case where a plurality of lighting fixtures inside the building are simulated has been described. However, the present invention is not limited to this, and a large number of lighting fixtures are provided as shown in the conventional example. This is particularly effective when lighting simulation is performed for a large-scale facility such as a stadium where equipment is installed, and enables a simulation image to be displayed in almost real time even when design changes are made.
