  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram illustrating a configuration example of an environment control system according to an embodiment. In the embodiment, an environment control system that controls a light environment in an indoor environment will be described as an example of the predetermined environment.

  The environment control system according to the embodiment includes a computer 11 and a camera 31.

  The computer 11 is connected to the camera 31 by wire or wirelessly, controls the camera 31, and acquires image data of an image generated by the camera 31.

  The computer 11 is a computer in which a control program for controlling each part of the environmental control system is installed. As illustrated in FIG. 1, the computer 11 includes a data reading unit 12, a storage device 13, a CPU 14, a memory 15, an input / output I / F 16, and a bus 17. The data reading unit 12, the storage device 13, the CPU 14, the memory 15, and the input / output I / F 16 are connected to each other via a bus 17. Further, an input device 18 (keyboard, pointing device, etc.) and a monitor 19 are connected to the computer 11 via an input / output I / F 16. The input / output I / F 16 receives various inputs from the input device 18 and outputs display data to the monitor 19.

  The data reading unit 12 is used when reading image data and the above control program from the outside. For example, the data reading unit 12 communicates with a reading device (such as an optical disk, a magnetic disk, or a magneto-optical disk reading device) that acquires data from a removable storage medium, or an external device in accordance with a known communication standard. It consists of communication devices (USB interface, LAN module, wireless LAN module, etc.) to be performed.

  The storage device 13 is configured by a storage medium such as a hard disk or a nonvolatile semiconductor memory. The storage device 13 stores a control program and various data necessary for executing the program.

  The CPU 14 is a processor that comprehensively controls each unit of the computer 11. The CPU 14 executes the above-described control program to perform the performance evaluation image generation unit 21, the first determination unit 22, the second determination unit 23, the calculation unit 24, the first determination unit 25, and the second determination unit. 26 and the calculation unit 27 (the performance evaluation image generation unit 21, the first determination unit 22, the second determination unit 23, the calculation unit 24, the first determination unit 25, the second determination unit 26, and the calculation unit 27). Each operation will be described later).

  The memory 15 temporarily stores various calculation results in the control program. The memory 15 is composed of, for example, a volatile SDRAM.

  The camera 31 is a device that acquires a luminance image based on luminance information in the environment to be controlled. In addition, since this environment control system is for controlling the light environment in a worker's visual field, the arrangement position and arrangement direction of the camera 31 may correspond to the above-described worker's visual field. Preferred (details will be described later).

  The operation of the environmental control system configured as described above will be described with reference to the flowchart shown in FIG.

  In step S <b> 1, the CPU 14 executes grasping of the space and grasping of the current state in order to acquire information indicating the environment to be controlled.

  Specifically, the CPU 14 executes part or all of the following (1) to (3).

  (1) Understanding the building outline and the current light environment based on user operations. These items are basically performed based on a user operation via the input device 18 (keyboard, pointing device, etc.). At this time, a plurality of options may be prepared in advance according to the characteristics of each item, and the user may select any one using the input device 18, or the user may use the input device 18 to set a numerical value. It is good also as a structure which inputs directly. Although an example of the items is shown below, these items are examples, and it is not always necessary to include all of them, and items other than the items shown below may be used.

(1) -1 Outline of the building / Use of space (office, residence, etc.)
・ Space area ・ Space ceiling height ・ Window position (direction, lighting performance, etc.)
-Reflectance of materials (walls, floors, partitions, etc.) (including Munsell value, outdoors)
・ Window transmittance (visible light)
・ Location of building (existence of surrounding buildings, etc.)
-Surrounding building height-Furniture position in the space (1) -2 Lighting environment-Daylight introduction status-Artificial lighting information (light distribution, installation position, installation position, etc.)
・ Illuminance of the space ・ Brightness of the space ・ Brightness of the space ・ Glare of the space ・ Problems in the light environment ・ Requests for the light environment (2) Understanding the outline of the building and the current light environment by conducting measurements in advance To do.

  When actual measurement in the control target environment is possible, actual measurement is performed in advance in order to grasp each item described in (1) in more detail and to confirm the accuracy of simulation described later. In the actual measurement, the user measures the luminance image and the illuminance.

  Here, the luminance image is, for example, one of the XYZ color system and the L * a * b * color system, which is a psychophysical color system (color system based on photometric quantity). It is an image regarding a certain XYZ color system. The luminance image is an image representing the distribution of psychophysical colors, and is, for example, three images (X image, Y image, Z image) corresponding to each of the tristimulus values (X, Y, Z).

  The CPU 14 causes the performance evaluation image generation unit 21 to generate a performance evaluation image based on the luminance image. The performance evaluation image is an image (also referred to as a view image) representing the degree of human perception, and includes, for example, a brightness image, a brightness examination image, and a glare image. The brightness image is disclosed in detail in the re-publication WO2006 / 132014 by the inventors. The brightness examination image is an image obtained by redisplaying the above-described brightness image in five ranges (for example, red, yellow, green, blue, and black) based on the brightness scale value (NB). is there. In the brightness examination image, the wider the region in a predetermined range (for example, the yellow region), the brighter the environment appears. The brightness scale value (NB) is disclosed in detail in Japanese Patent Application Laid-Open No. 2012-226707 by the inventors. The glare image is an image relating to glare, and the details thereof are disclosed in detail in Japanese Patent Application Laid-Open No. 2007-292665 by the inventors. By using such a performance evaluation image, it is possible to grasp in detail the location where light is excessive or insufficient, the location where glare is felt, and the like.

  The measurement of the luminance image may be performed using the camera 31 described above, or may be performed using another luminance measurement camera. However, the viewpoint to measure is preferably centered on the entire space and the desk surface. For example, it is preferable to include all of “two or more viewpoints for understanding the entire space”, “a viewpoint on a desk surface in a typical light environment”, and “a viewpoint on a desk surface in a poor light environment”. In the case of an office space, the viewpoint height to be measured is preferably the height of the line of sight where the user is seated (for example, 1.2 m). As for the light environment, it is preferable to photograph “artificial illumination only (night illumination)”, “daylight only”, and “daylight + artificial illumination” and measure three types of luminance images. In addition, since it is indispensable at the time of the simulation mentioned later, the luminance image of “artificial illumination only (night illumination)” among the above-described three types is surely measured.

  The illuminance is measured using an illuminometer (not shown). The illuminance meter may be an illuminance sensor provided in the camera 31 described above, or may be another illuminance meter. The viewpoint height to be measured may be, for example, a desk surface height (for example, 700 mm). In addition, the measurement of illuminance may be performed on the desk top surface and the entire room every 2 to 3 m, for example, in addition to the place where the luminance image is measured on the desk top surface.

  (3) Create a 3D model and check the simulation accuracy.

  In order to grasp the viewpoint that cannot be considered in real space and the light environment that introduces daylight that changes according to the season and time, simulation is used in the steps described later. Therefore, before the simulation, the simulation accuracy is checked as part of grasping the space and grasping the current situation. The CPU 14 creates a 3D model simulation under the same light environment conditions as the actual measurement described in (2) and each item described in (1), and compares the simulation with the actual measurement described in (2). If the difference is larger than a predetermined threshold, the CPU 14 may confirm the adjustment of the reflectance of the material, the light distribution of the artificial illumination, and the like to increase the simulation accuracy. Note that the simulation creation of the 3D model is performed in the same manner as in the known technique.

  In step S <b> 2, the CPU 14 causes the first determination unit 22 to plan an illumination concept. The lighting concept is related to the goal of environmental control, and the first determination unit 22 determines the required lighting requirement to be the target of environmental control according to the use of the space described in (1) of step S1 and the atmosphere. To do. As lighting requirements, “ensuring the brightness of the space”, “ensuring visual workability”, “glare”, “ensuring visibility of the visual target (when strictness is required)” and the like can be considered. The aim is to control daylight and artificial lighting appropriately and reduce energy by designing an appropriate lighting concept. The following are general lighting requirements for office spaces.

(1) Securing the brightness of the space The brightness image and the brightness examination image described in step S1 (2) regarding the brightness of the visual 40 degree zone that affects the brightness when a person looks at the space. Evaluate by More specifically, for example, the area of the yellow area (BA) of the brightness examination image is set to be five times or more than the area of the green area (GA). For example, the area ratio of the blue region (DA) of the brightness examination image is set to 10% or less. Also, for example, the red region of the brightness examination image is suppressed as small as possible. For example, in order to create a sharpness and atmosphere in the space, an area of 8.5-10 NB (orange) is created in the corners of the wall, ceiling, or space.

(2) Ensuring visual workability Evaluation of visual workability is performed using the brightness scale value (NB) set according to an allowable limit condition (JSLC: Just Slight Light Condition), which is the minimum condition that the user does not feel uncomfortable Do. In addition, it is also possible to simply evaluate using illuminance. More specifically, for example, “brightness when evaluating the paper (N9)” is set to 8.5 NB under uniform illumination conditions and 10 NB under non-uniform illumination conditions. Further, for example, the paper region in the brightness examination image is set to 8.5-10NB (orange region), and the peripheral region of the paper is set to 6-8.5NB (green and yellow region). Further, for example, when “VDT (monitor) and ambient brightness” is about 7 NB (not bright or dark) in the background, the monitor is set to about 8 NB, which is a little brighter than that. For example, when the background is about 5 NB (slightly dark), the background is set to about 9.5 NB. Further, for example, the illuminance is set to be illuminance 200 lx under uniform illumination conditions and illuminance 750 lx under non-uniform illumination conditions.

(3) Glare For example, the UGR value (United Glare Rating) at a viewpoint height of 1.2 m is set to 19 or less. However, this does not apply when daylight is included.

(4) Ensuring visibility of visual objects (when strictness is required)
For example, the visibility evaluation value of the main object is set to 2 SV (visible).

  The 1st determination part 22 performs the planning of an illumination concept by utilizing daylight effectively so that the above requirements may be satisfied. It should be noted that the daylight control satisfies the above conditions (1) and (2) (preferably (3) as well), and the artificial lighting control has been described above according to the presence or absence of the room or work. The conditions of (1) and (2) (preferably (3) are also satisfied).

  In step S <b> 3, the CPU 14 causes the second determination unit 23 to create a lighting plan and review control. In energy-saving lighting design, by actively using daylight, the output of artificial lighting can be reduced and the energy-saving effect can be enhanced. Therefore, the second determination unit 23 presupposes “daylight control” that effectively captures daylight and “artificial lighting control” according to the daylight introduction status, and the lighting concept described in step S2 Create a specific lighting plan that satisfies (lighting requirements).

(1) Daylight control The second determination unit 23 first examines a method for effectively capturing daylight. More specifically, we will consider a method of taking daylight efficiently by changing the specifications on the building side, etc., and increasing the brightness of the space without using artificial lighting as much as possible. For example, methods such as increasing the reflectivity of wall surfaces and ceiling surfaces in the space, providing ridges on windows, and providing blinds are conceivable. In addition, a method for appropriately controlling the captured daylight will be studied.

(2) Control of Artificial Illumination The second determination unit 23 has a plurality of patterns (for example, three patterns) in advance according to changes in daylight introduction status and illumination modes according to space usage. Then, by considering the illumination mode appropriately and creating an illumination plan and examining the control, it is possible to achieve both energy saving and appropriate brightness. An example of the illumination mode is shown below.

<Lighting mode 1> 150 lx or more in daylight only (almost no artificial lighting is required)
<Lighting mode 2> Floor surface illumination 75-150 lx
<Lighting mode 3> Floor surface illuminance of less than 75 lx (same artificial lighting as night lighting is required)
FIG. 3 shows the relationship between the artificial lighting fixture and the dimming rate necessary to satisfy the lighting concept (required lighting requirements) described in step S2 when four types of artificial lighting fixtures are included in the light environment to be controlled. Is shown for each illumination mode. These four types of artificial lighting fixtures are different in installation position (ceiling, wall, desk top, etc.) and dimming rate. As shown in FIG. 3, the lighting mode 2 has a relatively higher dimming rate than the lighting mode 1, and the lighting mode 3 has a relatively higher dimming rate than the lighting mode 2. It is high. This is because artificial lighting can be suppressed as daylight increases, and artificial lighting is required as daylight decreases.

  The 2nd determination part 23 determines the light control rate of artificial lighting according to the introduction condition of daylight. More specifically, the second determination unit 23 performs what control is performed when the artificial lighting control items (illuminance, luminance, brightness, etc.) and the set value (what value the control item is). ) And classify the lighting environment when daylight is introduced. At the same time, consider the control method (what is used to detect control items). Next, the second determination unit 23 determines the illumination mode according to the light environment classified as described above, and adjusts each artificial lighting fixture so as to satisfy the illumination concept (lighting requirement) described in step S2. Determine the amount of light.

In step S4, the CPU 14 causes the calculation unit 24 to calculate the energy of the artificial lighting fixture according to the information indicating the environment to be controlled described in step S1 and the lighting plan determined in step S3. The energy calculation is for calculating the energy consumed by the artificial lighting fixture, and the calculation unit 24 calculates the following items.
・ Total instrument luminous flux [lm]
・ Total power consumption [W]
・ Area [m ² ]
・ Power flux per square meter (ELF) [lm / m ² ]
・ Average energy consumption efficiency [lm / W]
・ Power consumption per square meter (LPD) [W / m ² ]
The CPU 14 may record the calculation result in the storage device 13, the memory 15, or the like, or may display the calculation result on the monitor 19.

  In step S <b> 5, the CPU 14 determines whether or not a predetermined energy saving condition is satisfied by the first determination unit 25 based on the result of the energy calculation executed in step S <b> 4. If the first determination unit 25 determines that the energy saving condition is satisfied, the process proceeds to step S6. If the first determination unit 25 determines that the energy saving condition is not satisfied (the energy saving effect is not sufficient), the first determination unit 25 returns to step S3 to create an illumination plan, and Perform control review. At this time, the CPU 14 reviews the appliance efficiency, the illumination rate, the dimming rate, the contents of the illumination mode, and the like, and recreates the illumination plan.

  In step S6, the CPU 14 causes the performance evaluation image generation unit 21 to create and check a performance evaluation image according to the information indicating the environment to be controlled described in step S1 and the lighting plan determined in step S3. . As described in step S1, the performance evaluation image is an image representing the degree of human perception (also referred to as an appearance image), and includes, for example, a brightness image, a brightness examination image, and a glare image.

  In step S <b> 7, the CPU 14 determines whether or not the performance condition is satisfied based on the result of the creation and confirmation of the performance evaluation image executed in step S <b> 6 by the second determination unit 26. The second determination unit 26 determines whether or not the lighting requirement is satisfied by comparing the performance evaluation image described above with the lighting concept (lighting requirement) described in step S2, and satisfies the lighting requirement. If yes, it is determined that the performance condition is satisfied, and the process proceeds to step S8. On the other hand, if the lighting requirement is not satisfied, it is determined that the performance condition is not satisfied, the process returns to step S3, and the lighting plan is created and the control is examined. At this time, the CPU 14 reviews the appliance efficiency, the illumination rate, the dimming rate, the contents of the illumination mode, and the like, and recreates the illumination plan.

  In step S8, the CPU 14 causes the calculation unit 27 to perform an annual energy amount calculation according to the information indicating the environment to be controlled described in step S1 and the lighting plan determined in step S3. The annual energy amount calculation is an example of an evaluation value related to the reduction rate of energy consumed by the artificial lighting equipment. In the following, the description will be made on the basis of one year. It may be.

  (1) Determine the annual lighting schedule.

  The lighting schedule is to determine the lighting mode for each hour for each sky condition (around the spring equinox, around the summer solstice, around the autumn equinox, around the winter solstice), and for every weather condition (clear or cloudy). As for the sky condition, latitude and longitude may be taken into account as necessary. The calculation unit 27 performs daylight simulation and determines the sky condition, the weather condition, and the illumination mode for each hour.

  FIG. 4 shows an example of the lighting schedule. 4, M1, M2, and M3 represent the illumination mode 1, the illumination mode 2, and the illumination mode 3 described in step S3, respectively. As shown in FIG. 4, since daylight changes somewhat according to sky conditions, weather conditions, and time, an illumination mode is determined according to the balance between daylight and artificial illumination.

  (2) “Evaluation value regarding energy reduction rate” of each illumination mode is calculated.

The calculation unit 27 calculates an “evaluation value related to the energy reduction rate” for each illumination mode. That is, the calculation unit 27 calculates an “evaluation value related to the energy reduction rate” when the illumination mode is switched according to the annual illumination schedule determined in (1). The calculation unit 27 calculates the following items as the “evaluation value regarding the energy reduction rate”.
・ Power flux consumption [lm ・ h]
・ Power consumption [W · h]
・ Average energy consumption efficiency [lm / W]
・ Power flux per square meter (ELF) [lm / m ² ]
・ Power consumption per square meter (LPD) [W / m ² ]
・ Average energy consumption efficiency per square meter [lm / W · m ² ]
(3) Calculate the annual energy amount of the current appliance.

  The calculation unit 27 calculates the annual energy amount based on the “evaluation value regarding the energy reduction rate” calculated in (2).

(4) “Evaluation value for energy reduction rate” considering annual lighting schedule is calculated. That is, the calculation unit 27 calculates the following items based on the values calculated in (2).
・ Electricity consumption per year (EPC) [kWh / year ・ m ² ]
・ Average energy consumption efficiency [lm / W]
・ Electric light flux consumption per year (ELFC) [klmh / year ・ m ² ]
The calculation unit 27 calculates the above-described values for the plan of the present proposal (the result of a series of processes in the flowchart of FIG. 2) as well as the above-described values for the conventional plan. Then, by comparing these, the energy reduction rate, that is, the energy saving effect is confirmed as a numerical value.

  The CPU 14 may record the calculation result in the storage device 13, the memory 15, or the like, or may display the calculation result on the monitor 19.

  FIG. 5 shows an example of comparison of values. The power consumption per year (EPC) in FIG. 5 is a value that simply indicates how much power is consumed in one year, and in the example of FIG. 5, an energy saving effect of nearly half is obtained. Moreover, the average energy consumption efficiency in FIG. 5 is a value indicating how many lumens of light are emitted per 1 W. In the example of FIG. This is wasteful and the efficiency is reduced when the artificial lighting fixture is centralized lighting. However, for example, the efficiency can be improved by changing the hardware configuration to distributed illumination or adopting LED illumination. Further, the power luminous flux consumption (ELFC) in FIG. 5 is a value indicating how much power luminous flux is consumed in one year. In the example of FIG. 5, an energy saving effect of almost half is obtained.

  As described above, according to the embodiment, information indicating the environment to be controlled is acquired, and a target for environmental control is determined based on the acquired information. Furthermore, the control content of the device is determined based on the determined target, and the energy consumed by the device is calculated according to the determined control content. Then, it is determined whether or not the control content is appropriate according to the calculated energy (first determination), and whether or not the control content is appropriate is determined based on the information described above (second determination). . Finally, when it is determined that the control content is appropriate by at least one of the first determination and the second determination, an evaluation value related to a reduction rate of energy consumed by the apparatus is calculated. Therefore, the energy of artificial lighting can be suppressed while ensuring appropriate brightness according to the environment to be controlled.

  In particular, according to the embodiment, a luminance image based on luminance information in a predetermined environment is acquired, and a performance evaluation image based on the acquired luminance image is generated as the above-described information. Appropriate processing can be performed in any environment, such as an environment in which daylight changes with a change.

  In the embodiment, the camera 31 has been described as an example of the means for acquiring the luminance image, but the present invention is not limited to this example. For example, it may be a two-dimensional color luminance meter or an imaging device having a plurality of sensors having different characteristics. Further, instead of including the camera 31, a sensor such as an illuminance sensor may be provided, and a luminance image may be acquired (generated) by estimating a luminance distribution based on the output. The luminance image and the various performance evaluation images may be appropriately displayed on the monitor 19 when the display is instructed by a user operation via the input device 18, for example.

  In the environment control system of the embodiment, the computer 11 and each artificial lighting device may be connected by wire or wirelessly, and the control of each artificial lighting device may be executed by the computer 11. In such a case, the light environment can be controlled more precisely while repeatedly controlling each artificial lighting fixture and controlling the luminance image acquired by the camera 31. Moreover, a more efficient process can be performed by installing an illuminometer permanently and monitoring it as needed.

  Moreover, the control content demonstrated by each step of the flowchart of FIG. 2 of embodiment is an example, and this invention is not limited to this example. For example, when creating a performance evaluation image in step S6 of FIG. 2, the processing can be greatly simplified by performing each processing using only the weather and the schedule.

  Further, in the embodiment, a part of the control content described in each step of the flowchart of FIG. 2 may be further automated by a computer, or may be realized by a user for customization purposes. . For example, it is good also as a structure which acquires weather information based on a well-known weather sensor, and it is good also as a structure which acquires various information, such as a weather information, via the internet.

  In the embodiment, the artificial lighting fixture has been described as an example of the device that affects the light environment, but the present invention is not limited to this example. For example, a light-shielding device such as a blind, a curtain, a roll screen, or a window material whose light transmittance can be changed actively or passively can be similarly used as a device that affects the light environment. Since the shading device is effective for daylight control, the control amount of the shading device, which is a device related to daylight, is preferentially determined, and the control shortage is related to light other than daylight (artificial lighting). It is good to make up with the control amount regarding the appliance etc.).

  An environment control program is also effective as a specific aspect of the present invention. The environment control program may be stored in a computer-readable medium, or may be stored in a Web server or the like and downloadable to the computer via the Internet. Similar to the environment control system described in each of the above-described embodiments by connecting the lighting device described in each of the above-described embodiments to a computer capable of controlling each unit and executing the above-described environment control program by the computer. This process can be realized, and the same effects as in the embodiment can be obtained.
