Description

The present disclosure relates to an environmental control system.

ABW (Activity Based Working) offices have emerged as a result of work style reforms. In the ABW office, for example, when a worker wants to do intensive work alone, when multiple people want to do group work, when he wants to take a break or relax, the type and amount of work that changes from moment to moment, or the emotions of the worker himself. It is an office that streamlines the performance of workers and organizations by allowing workers to select spaces with different design objectives in response to motivated intentions. As a method of creating a space having a different design purpose, for example, as described in Patent Document 1, a means of creating a space having the purpose of improving the efficiency of concentrated work by using furniture and furniture and performing zoning is known.

Japanese Unexamined Patent Publication No. 2017-131572

Ideally, the ABW office should undergo continuous zoning changes according to the fluid work performance of workers and organizations and the needs of each space. For example, the zoning of the booth-type furniture and furniture described above can be changed by changing the arrangement and number of furniture and furniture in response to the excess or deficiency of the utilization rate even after installation. However, while the work performance of workers and organizations and the needs for each space can occur even in cycles such as hourly, daily, and monthly, the work of transporting and re-installing furniture and furniture, storing in warehouses, etc. is described above. It is difficult to carry out continuously in this cycle in view of the labor and labor, and there is a problem as a means for realizing the ABW office in terms of flexibility of design change.

Therefore, the purpose of this disclosure is environmental control that enables active zoning that easily responds to the fluid work performance of workers and organizations that occur in cycles such as hourly, daily, and monthly, and the needs for each space. To provide the system.

In order to solve the above problems, the environmental control system according to the present disclosure includes a plurality of task lights for illuminating the work surface of the desk in a room where a plurality of desks are arranged, and a wider area than the work surface in the room. Of the multiple base lights for illuminating, the location information of one or more people in the room, the presence information of one or more people in the room, and the personal information of one or more people in the room. A sensor device and a control device for detecting at least one of the above are provided, and the control device includes a space control area for centralized work in which the illuminance of the task light is larger than the illuminance of the base light and the illuminance of the task light than the illuminance of the base light. Zone control is performed to control dimming and toning of a plurality of task lights and a plurality of base lights so that a space control area for decentralized work is generated, and the control device is based on information from the sensor device. When it is judged that the amount of the centralized work space control area is small, the control device controls the dimming and toning of multiple task lights and multiple base lights so that the amount of the centralized work space control area becomes large. Dimming and toning control of multiple task lights and multiple base lights so that the amount of the centralized work space control area becomes smaller when it is determined that the amount of the centralized work space control area is large based on the information from the sensor device. When the control device determines that the amount of the decentralized work space control area is small based on the information from the sensor device, the number of task lights and the plurality of task lights are increased so that the amount of the decentralized work space control area is large. When the control device determines that the amount of the decentralized work space control area is large based on the information from the sensor device, the amount of the decentralized work space control area is increased. One or more of dimming and toning control of a plurality of task lights and a plurality of base lights so as to be small is executed.

In this specification, the illuminance of the task light is larger than the illuminance of the base light on the plurality of work surfaces of the plurality of desks installed in the room where the environmental control system is installed in the space control area for centralized work. It is defined as the sum of one or more working surfaces. In addition, the illuminance of the task light is smaller than the illuminance of the base light on multiple work surfaces of multiple desks installed in the room where the environmental control system is installed in the space control area for decentralized work. It is defined as the sum of the work surfaces of. The sum of the work surfaces can be obtained as the sum of the areas using a scale such as a design drawing or a ruler, or can be obtained as the sum of the number of work surfaces. These are the quantities of the centralized work space control area or the decentralized work space control area. Further, in the present specification, the "quantity" may be defined as a physical quantity whose magnitude relationship can be defined, and the physical quantity may be defined to include a dimensionless quantity such as a number. Therefore, the "quantity" includes, for example, "area (area)" and "number".

According to the environmental control system according to the present disclosure, it is possible to realize active zoning that easily responds to the fluid work performance of workers and organizations and the needs for each space that occur in cycles such as hourly, daily, and monthly. ..

[Example 1]
(Purpose and outline of control aimed at by control in the environmental control system of the present disclosure)
In the first embodiment, first, the purpose and outline of the control aimed at by the control in the environmental control system of the present disclosure will be roughly described. After that, a detailed explanation of each configuration of the environmental control system and an example of specific control that can realize the purpose will be described.

FIG. 1 is a drawing showing an embodiment of a layout of a plurality of work desks D01 to D14 possible in an ABW office 20 as an example of a room in which the environmental control system 10 according to the first embodiment of the present disclosure is installed. The layout of the multiple work desks D01 to D14 when viewed from above, and the layout of the base light 3, the duct rail 4 for energization, and the task light 5 attached to the ceiling of the ABW office 20 are shown in the work desks D01 to D14. It is a layout layout drawing described in the form of superimposing on the arrangement of.

In one form of the ABW office 20 shown in FIG. 1, a total of 14 work desks D01 to D14, which are general office desks, are classified into desk group 1 and desk group 2, and the ABW office 20 is placed above the desk group 1. Twenty-eight LED dimming toning base lights (for example, NNLK41515 + NNL4600EXDK9: Panasonic) as ambient lighting for illumination were installed at equal intervals, and duct rails 4 for energization were installed in three rows in the vicinity thereof. Specifically, a total of 14 work desks D01 to D14 are arranged in 4 cases, and 3 duct rails 4 for energization are placed in the vicinity of 3 rows of work desks D01 to D14 out of 4 work desks D01 to D14. They were arranged so as to extend in a direction substantially parallel to the extending direction of the row.

Further, a total of 14 task lights 5 were installed on each duct rail 4. As the task light 5, an LED dimming spotlight (for example, NTS05121W: Panasonic) 5 was used. Further, a wavelength conversion filter was attached to the opening of each task light 5, and the color temperature of the output light from the task light 5 was adjusted to 6000K. Then, a total of 14 work desks D01 to D14 and a total of 14 task lights 5 are associated with each other on a one-to-one basis so that each task light 5 illuminates the central portion of the corresponding work desks D01 to D14. The installation position and installation direction of the task light 5 were adjusted.

The 28 base lights 3 and 14 task lights 5 include a multi-manager (for example, NQ51101: Panasonic), an LS / PD signal conversion interface (for example, NK51111: Panasonic), and PD / adjustment as examples of control devices. It was sequentially connected to an optical signal conversion interface (for example, NK51012: Panasonic) and PiPit + separate cell control A type (for example, NQ23171Z: Panasonic) via a dimming signal line. Two task lights 5 were paired with each of the two PiPit + separate celcon A type.

Further, the dice sensors S1 to S14 are arranged on the work surfaces of the work desks D01 to D14. The dice sensors S1 to S14 are dice-type IoT devices having a substantially cubic shape similar to the dice, and are dice-type devices "electronic dice" having an acceleration sensor and a wireless communication function. The dice sensors S1 to S14 are arranged on the work surface so that a person (worker) can select a desired mode. Specifically, the six surfaces of the dice sensors S1 to S14 vote (desired) for the centralized work space control area and the decentralized work space control area. It includes a surface that means being present and a surface that means neutral, which means that neither of those two spaces is selected.

Each dice sensor S1 to S14 is a built-in acceleration sensor, detects how much it has rotated in which direction, and determines which surface is facing upward. Then, each dice sensor S1 to S14 transmits the result to a terminal including a calculation unit through a wireless communication network constructed in the ABW office 20, for example, the above multi-manager, a doublet, a smartphone, a personal computer, or the like. Send to the operation terminal consisting of. Here, when using the ABW office 20, when the work is completed and the person leaves the seat, the person is obliged to leave the seat with the dice sensors S1 to S14 facing up, which means neutral. ing. For this reason, in the multi-manager or the operation terminal, how many people are working with the work desks D01 to D14, and how many of the working people desire a space control area for centralized work. It is possible to determine how many of the workers want a space control area for decentralized work. A plurality of dice sensors (14 dice sensors in the case of the first embodiment) S1 to S14 constitute a sensor device. As the wireless communication method of the dice sensors S1 to S14, a method conforming to the IEEE 802.15.4 standard can be preferably adopted.

Next, using the operation application of the multi-manager, the position information of each base light 3 is stored by the mapping work of 28 base lights 3, and as shown in FIG. 1, 12 base lights 3 and 8 units are stored. The task light 5 is set as a lighting device belonging to the lighting group 1, the four base lights 3 are set as the lighting devices belonging to the lighting group 2, and the 12 base lights 3 and the six task lights 5 are illuminated. It was set as a lighting device belonging to group 3. Further, as shown in FIG. 2, four scenes were set for each of the lighting groups 1 to 3, and the color temperature and dimming rate values were set for each group in each scene.

Here, the setting of each scene can be easily executed by using an operation terminal in which the application of the existing scene setting is installed, for example, a smartphone, a tablet, a remote controller, or the like. Then, each scene was actually reproduced. Specifically, when the blind curtain of the window of the ABW office 20 was closed and the scene 1 was reproduced using the operation unit 64 (see FIG. 3), the desk group 1 and the desk group 2 were divided in appearance. .. Subsequently, when other scenes such as scenes 3 and 4 were sequentially reproduced using the operation unit 64 (see FIG. 3), each scene was switched in about a few seconds.

In the desk group 1 of the scene 1, the illuminance was high only in the central portion of the work desks D07 to D014, and the illuminance decreased as the distance from the central portion increased, resulting in a non-uniform illuminance distribution. In addition, the illuminance of the floor and walls around the work desk was low, and the space had a low sense of brightness. Further, in the desk group 1 of the scene 1, the illuminance of the task light was larger than the illuminance of the base light on the work surface of each work desk D07 to D014. In the present disclosure, the work surface of a work desk where the illuminance of the task light is larger than the illuminance of the base light is defined as a space control area for centralized work. When a person working using the work surfaces of the work desks D07 to D014 wants the work surface of the work desks D07 to D014 that he / she is using to be a space control area for centralized work, the dice sensors S1 to S14 are used. It is the space for intensive work that is used to vote (desired).

On the other hand, in the desk group 2 of the scene 1, the illuminance of the work desks D01 to D06 has a higher uniform illuminance distribution than that of the desk group 1, and the illuminance of the floor and walls around the work desk is also high, and the feeling of brightness is high. It was a space. In the desk group 2 of the scene 1, the illuminance of the task light was smaller than the illuminance of the base light on the work surface of each work desk D07 to D014. In the present disclosure, the work surface of a work desk in which the illuminance of the task light is smaller than the illuminance of the base light is defined as a space control area for decentralized work. Dice sensors S1 to S14 when a person working using the work surfaces of the work desks D07 to D014 wants the work surface of the work desks D07 to D014 that he / she is using to be a space control area for decentralized work. It is a decentralized work space to vote (desired) using.

At this time, when the worker is seated in the desk group 1, the illuminance is high only in the central part of the work desks D07 to D014, which the worker should pay more attention to, so that the cognitive noise factor of the peripheral visual field is reduced, so that the worker It is easy to immerse yourself in the work and improve the efficiency of intensive work. Further, in this method, since the dimming rate of the base light 3 is set low, the visibility of the peripheral visual field such as the wall or the floor is lowered, so that the work desks D07 to D014 and the work are more absorbed. It is easy to increase the effect. In addition, because the dimming rate of the base light 3 is set low, the worker working in the desk group 1 may not be able to see the facial expression well or may be on the face when other workers see it from the outside. It's hard to talk to because it looks moody because of the shade. That is, the worker working in the desk group 1 tends to be talked to by another worker and the probability that the work is interrupted tends to decrease, and as a result, the efficiency of the intensive work tends to be improved. From the above, when the scene 1 is reproduced, the desk group 1 is a space that easily functions as a concentrated space. On the other hand, in scene 1, the desk group 2 is a space that easily functions as a non-concentrated space (relaxation space, co-creation space) because the color temperature is low and it is easy to relax and increase the amount of communication between a plurality of people.

The illuminance distribution in the space is significantly different between the desk group 1 and the desk group 2. In particular, the desk group 1 is characterized in that the illuminance of the floor and walls around the work desk is lower, which causes a high sense of division of the space in appearance between the two desk groups. Further, since the color temperature of the illuminations of the desk group 1 and the desk group 2 are significantly different from each other, the appearance of the space is highly divided. From the above, it has a cognitive zoning effect that divides the space without using furniture or furniture. As for the zoning effect, the larger the difference in the illuminance distribution and the color temperature of each group, the easier it is to enhance the effect.

Further, the desk group 1 and the desk group 2 have different work contents to be urged to the workers. For example, the desk group 1 of this embodiment promotes intensive work, and the desk group 2 promotes relaxation and communication. Therefore, only in appearance. In addition, there is a difference in the functional usage of each space, so this effect also contributes to the zoning effect.

When zoning is performed by this method, switching of each scene is completed in a few seconds, and as a result, the layout of the ABW office 20 can be changed in a few seconds. For example, when the number of desired space control areas for centralized work becomes relatively large using the dice sensors S1 to S14 due to circumstances such as busy days in the office where the need for concentrated space is high, each dice sensor The arithmetic unit that receives the signals from S1 to S14 determines that the need for the centralized work space is high, and switches the scene from scene 1 to scene 3 via the multi-manager, and the centralized work space of the ABW office 20. The control area is increased from 8 work planes to 14 work planes. Alternatively, when the desired number of centralized work space control areas using the dice sensors S1 to S14 becomes relatively large, the operation terminal receiving the signals from the dice sensors S1 to S14 becomes the centralized work space. By controlling the multi-manager, the scene is switched from scene 1 to scene 3, and the space control area for centralized work of the ABW office 20 is increased from 8 work planes to 14 work planes. .. In this way, meeting the needs of a concentrated space for workers can result in better work performance for workers and organizations.

Alternatively, when the number of desired non-concentrated work spaces using the dice sensors S1 to S14 becomes relatively large due to circumstances such as fallow days, the calculation unit that receives the signals from the dice sensors S1 to S14. However, judging that the need for the space control area for decentralized work is high, the scene is switched to scene 4 via the multi-manager to reduce the space control area for decentralized work of the ABW office 20, while for decentralized work. The spatial control area is increased from 8 work planes to 14 work planes. Alternatively, when the desired number of decentralized work spaces using the dice sensors S1 to S14 becomes relatively large, the operation terminal receiving the signals from the dice sensors S1 to S14 controls the decentralized work space. Judging that the need for the area is high, the scene is switched to the scene 4 via the multi-manager to reduce the centralized work space control area of the ABW office 20, while the decentralized work space control area is set to 8 work surfaces. To 14 work planes. In this way, while reducing the space control area for intensive work, by making the space control area for non-central work 14 work surfaces, the co-creation space can be increased, and the stress of the organization can be reduced and communication can be achieved. It has the effect of easily increasing the amount. Further, at this time, it is not necessary to immediately switch the scene by the control by the multi-manager or the control by the multi-manager via the operation terminal. For example, after receiving a signal suggesting such a worker's request, if the scene is switched after the lunch break of the ABW office or at the opening time of the next day, the worker who is already working suddenly This is preferable because it can reduce discomfort and discomfort due to changes in the environment. In the configurations described so far, the receiving unit and the arithmetic unit that receive the signals from the dice sensors S1 to S14 do not have to be inside the multi-manager housing. In this case, the control device may include a receiving unit, a calculation unit, and a multi-manager that receive signals from the dice sensors S1 to S14.

Further, the control device learns (analyzes) the tendency of the needs of the centralized work space control area and the tendency of the needs of the decentralized work space control area at each time of the week based on the information from the dice sensors S1 to S14. ) May. Then, the control device identifies the needs of the centralized and decentralized work space control area in the afternoon (or morning) of a predetermined day of the week (for example, Thursday), and realizes the needs based on the specified needs. May be selected.

According to this method, active zoning that changes the layout in cycles such as hourly, daily, and monthly, which is difficult with the above-mentioned method using furniture and furniture, is possible. In the conventional office scene, it is common to illuminate areas such as work desks and aisles with high uniformity of color temperature and illuminance distribution. On the other hand, since the present application uses such a lighting method and a control method for making the color temperature and the illuminance distribution non-uniform, it meets the needs of the space control area for concentrated and decentralized work, especially in the ABW office scene. As described above, the allocation of the space control area for centralized and decentralized work can be executed flexibly and quickly, and a remarkable effect that could not be predicted by the conventional knowledge of lighting can be realized.

(Detailed description of each configuration included in the environmental control system 10)
The purpose and outline of the control aimed at by the control in the environmental control system 10 of the present disclosure have been described above. Next, each configuration included in the environmental control system 10 will be described in detail. FIG. 3 is a block diagram showing an example of a main configuration capable of forming the environmental control system 10. As shown in FIG. 3, the environmental control system 10 has an operation unit 64 in addition to a control device 61 composed of dice sensors S1 to S14, a base light 3, a task light 5, and a multi-manager, and the control device 61. Includes a control unit 61a, a dimming and toning signal transmission unit 61b, a calculation unit 61c, and a storage unit 61d. The control device 61 is preferably configured by a computer, for example, a microcomputer, and the control unit 61a, that is, the processor includes, for example, a CPU (Central Processing Unit). Further, the storage unit 61d is composed of a non-volatile memory such as a ROM (Read Only Memory) and a volatile memory such as a RAM (Random Access Memory). The CPU reads and executes a program or the like stored in advance in the storage unit 61d. In addition, the non-volatile memory stores a control program, a predetermined threshold value, and the like in advance. In addition, the volatile memory temporarily stores the read program and processing data. The storage unit 61d stores position information and device identification information regarding each of one or more preset task lights 5 and the plurality of base lights 3. Further, the storage unit 61d stores dimming and toning data that reproduces the above-mentioned scenes 1 to 4. In the first embodiment, the eight work desks D07 to D014 belong to the desk group 1, and the six work desks D01 to D06 belong to the desk group 2, but the work desks belong to the desk group 1 and the desk group 2. The number of is not limited to the case of Example 1. Further, the number of lighting groups is not limited to three as in the first embodiment, and any number of lighting groups of two or more may exist. Next, the position information, the device identification information, and each configuration included in the environmental control system 10 will be described in detail.

(About information)
<Location information>
The position information may be information similar to the absolute value of the coordinates such as the actual position in the space, or the relative positional relationship based on a certain task light, a base light, or an existing pillar in the space. Information is also acceptable. Further, the position information stored in the storage unit 61d does not have to be able to completely reproduce the positions and positional relationships of the actually installed task lights and base lights, and may be information that can only partially reproduce (define). Further, the position information may be recorded in the storage unit by input by the user, or may be recorded by AI or a computer algorithm. Further, the position information may be set / recorded while referring to the drawing data separately stored in the storage unit or the like, or being associated with the drawing data. Further, the location information does not have to be given or associated with all the devices included in the environmental control system, and may be appropriately selectable according to the user's circumstances.

<Device identification information>
The device identification information is information that can identify a device of a spotlight or a base light, and is composed of, for example, a manufacturing number, a MAC address, an IP address, a product number, and the like. The device identification information is used in the environment of each device, such as when setting / recording the above-mentioned position information, groups, and scenes, or when individually setting / recording the output parameters (color adjustment rate, dimming rate, etc.) of the device. It is used in a control system so that different devices are not unintentionally identified as the same. The device identification information does not have to be assigned or associated with all the devices included in the environmental control system, and the device to be assigned or associated can be appropriately selected according to the user's circumstances.

(Specific aspects of each configuration)
<Task light>
The device form of the task light is not particularly limited, and as the task light, in addition to the above-mentioned spotlight, a desk light, a downlight, etc. can be adopted, but as the task light, a specific area such as a spotlight can be adopted. It is preferable that the light distribution is controlled so as to collect light in the work desk because it is easy to control the lighting range of the work desk. More specifically, the spotlight may have a structure in which a person adjusts the irradiation direction of the spotlight by applying an external force, and the spotlight can be freely rotated by a motor or the like with a remote controller. The structure may be such that the irradiation direction of the light can be automatically adjusted in any of the downward directions. If at least one spotlight can change the emission direction of the illumination light in any direction at the installation position, the degree of freedom of the gap between the work desks in the longitudinal direction in the centralized space can be increased, and the width in the centralized space can be increased. The degree of freedom in the gap between the work desks in the direction can be increased, and the degree of freedom in the layout of the concentrated space can be increased. Further, when at least one spotlight has a format in which the irradiation direction of the spotlight can be freely adjusted by a remote controller, the irradiation direction of the spotlight can be safely adjusted from the ground without using a stepladder or the like. Further, as described above, it is preferable to use a dimming toning type spotlight as the task light.

The task light is a light for improving work efficiency of a worker's work, for example, a personal computer operation work, a writing work, a reading work, etc., and is a light that is selectively illuminated on a visual target area of a work desk. The visual target area is an area that can be generally seen when working on a work desk. For example, when a personal computer (hereinafter, simply referred to as a personal computer) is placed behind the center of the work desk for operation. The central part of the work desk is the center of the visual field area. At this time, changes in the visual object due to physiological factors or accidental changes in posture or line of sight are not taken into consideration, that is, looking up at the ceiling for temporary thinking or stretching, moving the line of sight to the wall, or sneezing. Events such as shifting the line of sight to the floor due to sneezing or coughing, or shifting the line of sight due to someone talking to them are not considered as significant changes in the visual target area on the work desks D01 to D14.

The illumination range of the task light is preferably limited to a part of the visual target area, and for example, the illumination range is preferably 30% to 90% with respect to the area of the work desk. The illumination range of the task light is not particularly limited, but is preferably substantially circular or substantially polygonal. By doing so, the brightness of the visual target region becomes brighter than the brightness of the region other than the visual target region, and the cognitive noise of the peripheral visual field is reduced. Therefore, the worker's consciousness is directed toward the work desk side, and it is easy to improve work efficiency.

Here, the illumination range can be calculated as a position where the maximum value of the amount of light per unit area reaching the work desk is halved, and is generally a range called a half width. The illumination range can be measured and calculated by using a known illuminometer. The color temperature of the task light is not particularly limited, but it is preferable that the color temperature is 4000K to 6500K because it is easy to enhance cognitive concentration.

<Base light>
The base light is a lighting for increasing the brightness of the room, and is a lighting that uniformly illuminates the room. The light distribution of the base light is preferably wider than that of the spot light in order to uniformly illuminate the room. The color temperature of the base light is not particularly limited. The base light is preferably a dimming toning type. The device form of the base light is not particularly limited, and any device such as a ceiling light, a line light, a pendant light, a spotlight, and a light bar can be used.

<Sensor device>
The sensor device can detect at least one of the position information of one or more people existing in the room, the presence information of one or more people existing in the room, and the personal information of one or more people existing in the room. Any device may be used. For example, in the first embodiment, the case where the sensor device is composed of a plurality of dice sensors will be described, but one sensor device is attached to each of the chairs having the same number as the number of work desks D01 to D14. It may be a seated sensor (weight sensor), or a motion sensor (optical sensor) that can detect whether or not a person is seated for each chair.

Alternatively, the sensor device may be a device that can identify the distribution of people in the room, or may be an LPS (Local Positioning system) (trademark registration), a camera, a LIDER, or the like that can detect the position information of people. The LPS includes a beacon, a scanner, and a control device that transmit position information by a person (directly possessed by the person or attached to an object possessed by the person). A scanner installed on the ceiling receives the signal from the beacon and measures the position information. The control device identifies the distribution of people in the room by receiving the position information. The camera may be a camera system including an image analysis unit that analyzes the number of people and facial expressions based on the captured image. The LPS may be an LPS system including a position information analysis unit that analyzes the number of people and the space utilization rate based on the position information. Alternatively, the sensor device may be a device for measuring voice in a room, a microphone, or the like. The microphone may be a microphone system in which a voice analysis unit that analyzes the number of people and a state based on the recorded voice is provided inside or outside the microphone body. By using such a device as a sensor device, it becomes easy for the worker to automatically determine the control method of the control device without performing an operation action on any terminal, which is preferable.

Alternatively, the sensor device may be an ID information acquisition device such as a card reader that detects ID information (identification information). In this case, the control device is, for example, a person in a department who often uses either the centralized work space or the non-centralized work space as personal information of each worker based on the information from the ID information acquisition device. You can judge which space you like.
Alternatively, after the ID information is detected, the desired mode may be stored wirelessly or by wire in a cloud server or the like so that the information can be learned. That is, learning may be performed by combined detection of ID information and other sensors, and the control device may automatically determine the space desired by the person who has detected the ID information based on the learning.
The ID information includes, for example, identification number, identification symbol, name, gender, organization, schedule information, information about terminals used in business, action history, information about vitals, facility reservation information of workers associated with the ID. , Personnel information, and other attribute information in the office may be included, and such information may contribute to the control method of the control device.

Further, the personal information includes information for declaring (desiring) a request for a control mode of the office space of each worker, such as a desired space control area for centralized work or a desired space control area for non-centralized work. As an example of controlling only with personal information, a mode desired by the person is set in advance in an application of an operation terminal such as a smartphone, and the operation terminal is detected by a detection device (in this case, the mode). By approaching the detection device (which becomes a sensor device), the detection device may be made to read a desired mode, and the mode may be transmitted to the control device. Alternatively, the sensor device may be an operation unit (consisting of an operation interface or the like) for inputting a desired mode when entering the room. Then, when a person enters the room, he / she may be able to select a space for intensive work or a space for non-concentrated work. In addition, the personal information intended in the present application includes, for example, anonymous information obtained through an electronic dice, an electronic voting system, etc., in which the person who is the root of the declaration (desired) is not specified. In other words, the declaration (desired) and the worker attribute information do not necessarily have to be linked.

<Control device>
The control device 61 is a device for controlling the task light and the base light. Here, the control includes ON / OFF control and dimming / toning control. The device form of the control device 61 is not particularly limited, but as the device form of the control device 61, for example, the lighting control device and the control application of the lighting control device described in the first embodiment can be preferably adopted. The device control application may be installed on another terminal such as a tablet, a personal computer, or a smartphone in addition to the multi-manager illustrated in FIG. 3. In this case, it is easy for the user to set, manage, and operate the lighting control device. Therefore, it is preferable.

Specifically, in the example shown in FIG. 3, for example, the control device 61 configured by the multi-manager directly receives the signal from the dice sensors S1 to S14. However, as shown in FIG. 4, for example, the control device 71 configured by the multi-manager may be controlled by receiving a signal from the operation terminal (for example, a tablet or a smartphone) 79. Then, in this case, the operation terminal 79 may receive a signal from the dice sensors S1 to S14 and transmit a control signal to the control device 71 based on the received signal. Further, the operation terminal 79 may have a calculation unit 73 and an operation unit 75. That is, the control device 71 of the environmental control system 70 may be a terminal or device different from the operation terminal such as the tablet 72, or may be configured by a multi-manager or the like. Here, the control device 71 may have its housing embedded in the ceiling or wall surface, or may be stationary on the ground or a storage shelf. Further, the control device 71 may be controlled by wire communication with an operation terminal such as a tablet 72, or may be controlled by wireless signal communication such as Wi-Fi or Bluetooth (registered trademark). .. In this case, although not particularly shown in FIG. 4, the control device 71 may include a communication device having a port for connecting a signal line for communication and a wireless LAN access point. Further, at this time, the tablet 72 or the like does not have to directly communicate with the task light 5 or the base light 3. At this time, information on the positions and control conditions of the appliances constituting the environmental control system 70, such as mappings, scenes, groups, and control schedules set by using the operation unit 75 of the tablet 72, is transmitted to the control device 71, and the control device It may be recorded in the storage unit 76 of 71. In this case, the intended environment control can be performed even when the power of the tablet 72 is turned off or the tablet 72 is stored in a place outside the communication range with the task light 5 and the base light 3. Further, the control device 71 does not have to have a user interface for operation such as a liquid crystal display. In this case, the control device 71 is preferable because it is easy to miniaturize, and the ease of installation and the designability are improved. Although not particularly shown in FIG. 4, an operation terminal such as a tablet 72 may have a storage unit. Further, the environmental control system 70 shown in FIG. 4 is a modified example of the environmental control system 10 shown in FIG. 3, but the environmental control of a modified example in a mode that can be realized and is easy to conceive other than the environmental control system 70 shown in FIG. It is clear that there are many systems.

<Calculation unit>
The calculation unit includes a calculation process for determining a need regarding the amount of office space based on the information obtained from the sensor device, for example, in the present application, the ratio of the amount of the centralized work space or the non-concentrated work space. As shown in FIG. 3, the calculation unit 61c may or may not be incorporated in the control device 61 which is composed of, for example, a multi-manager and directly performs dimming / coloring control. Then, as shown in FIG. 4, when it is not incorporated inside the control device 71 that directly performs dimming / coloring control, an information device different from the control device 71 that directly performs dimming / coloring control, for example, , A smartphone, a tablet, an operation terminal such as a personal computer, a server or workstation on the cloud, an external storage medium, or the like. The arithmetic unit executes pre-programmed arithmetic processing, but the program may be rewritten during use. The program may be rewritten by a person via editor software or a personal computer, or by AI or the like unattended and automatically based on the learning results of past accumulated data. The arithmetic processing included in the arithmetic unit is not particularly limited in the range of processing the information obtained from the sensor device, but for example, desired information voted by a plurality of workers can be aggregated by four arithmetic operations, or LPS. Needs regarding the amount of office space by aggregating the number of people information obtained from systems and camera systems by four-rule calculation, and by statistical calculation means such as regression analysis based on the above-mentioned aggregated information and past accumulated data May be predicted. The calculation result obtained by the processing in the calculation unit is fed back to the control device which is composed of, for example, a multi-manager and directly performs dimming / color adjustment control, and contributes to at least a part of the control method of the control device. This is preferable because it enables flexible response to the ever-changing situation of the office. In addition, the calculation result of the calculation unit does not necessarily have to be fed back to the control device that directly controls dimming and toning. For example, it can be used for graphs of changes in usage conditions over time in each space and for the performance of workers and organizations. Such information may be output. This is preferable because it makes it easier for office managers and general affairs personnel to understand how the office is used and the performance of workers and organizations that are usually difficult to continuously recognize.

<Dimming and toning signal transmitter>
The dimming toning signal transmission unit 61b is a part that transmits a dimming toning signal to the task light and the base light to execute at least one of dimming and toning, and is included in the control device 61. is there. The signal format is not particularly limited, and any known dimming signal, Wi-Fi, Bluetooth (registered trademark), or the like can be used. In the above-mentioned dimming and toning control, the dimming and toning control of the digital control method has been described, and the control method for transmitting a digital signal (PDCL) from the light control has been described. Here, in this control method, in addition to the power supply line, wiring of a signal line for digital control is required. In this digital control, since detailed information can be communicated, it is possible to perform control using a large amount of information, and control by a wireless signal is also included in this method.

However, when performing dimming and toning control, a phase control method may be adopted, or dimming control may be executed by directly adjusting the power to the lighting equipment. In this method, since the power supply current to the lighting equipment is directly controlled, it is easily affected by voltage fluctuations, but it is not necessary to draw a dedicated signal line separately, so that it is excellent in workability. Alternatively, when performing dimming and toning control, a signal line method may be adopted, and a dimming signal (duty signal) is sent from the light control, and the brightness of the light emitting part such as an LED is adjusted by the power supply unit on the device side. You may control it. This method requires wiring of a dimming signal line in addition to the power supply line, but since it is not easily affected by the wire voltage, smooth dimming control without flicker is possible. It should be noted that the control of only ON / OFF of the task light and the base light is also included in the dimming control.

<Memory>
Any known device may be adopted as the device constituting the storage unit. Further, unlike the configuration shown in FIG. 3, the storage unit does not have to be incorporated inside the control device. For example, an information device different from the control device that directly performs dimming / color adjustment control, for example, a smartphone. It may be composed of a tablet, a personal computer, a server or workstation on the cloud, an external storage medium, or the like. The storage unit is basically set by the user, but it may be rewritten and set by the machine in the cloud or AI.

<Group information of multiple devices>
Group information of a plurality of lighting devices is managed by, for example, an application. Grouping may be set and saved by operating a tablet terminal, for example. The same command is sent to the grouped devices all at once, and for example, the same dimming and toning control is applied. Regarding dimming and toning control of a plurality of grouped devices, that is, group control, signal delay is allowed, and variation in device operation is also allowed. For example, the permissible variation in device operation is within 30 minutes, more preferably within 10 minutes, even more preferably within 1 minute, most preferably within 10 seconds, and a signal or signal that falls within this range. The instruction delay is included in the behavior of the grouped devices. When the operation variation of the equipment is within the above time, it is preferable because the layout change can be easily achieved quickly and labor-savingly as compared with the layout change involving the transportation and re-installation of general furniture and furniture. The group setting may be included as a function of the application that operates the control device, but it is not always defined by the name of "group". It is preferable to set a group in the application for operating the control device or the storage unit included in the control device because it is easy for the user to manage and change the lighting and its control parameters.

<Control scene information>
It is a very complicated task for the user to set and reproduce control parameters such as dimming rate and toning rate of each lighting device for a plurality of lighting devices. This is because a general ABW office uses 10 or more or 30 or more lighting devices, and in many cases 100 or more. Therefore, a method of collectively storing and managing control parameters of a plurality of lighting devices in a storage unit is known, and this is referred to as a scene in the present application. By doing so, not only is it easy for the user to manage the conditions of the control parameters for a plurality of lighting devices, but also those conditions can be instantly reflected in the plurality of lighting devices at a desired timing (hereinafter, hereafter. (Referred to as regeneration) is also easy, which is preferable. Further, the user can instantly switch between two or more intended setting conditions by storing a plurality of types of scenes in the storage unit in advance. The settings of each scene may be set in any way according to the specification needs. For example, unlike the example shown in FIG. 2, the dimming rate of 10 base lights in scene 1 is set to 100%. It may be stored in the storage unit, and further, the dimming rate of the above-mentioned 10 base lights may be set to 30% in the scene 2 and stored in the storage unit. Then, when the scene 1 is played back, the dimming rate of the 10 base lights is instantly set to 100%, and when the scene 2 is played back from this state, the 10 base lights are instantly set. The dimming rate of the above may be set to 30%. In this way, it is preferable that the dimming control of a large number of lighting devices can be realized in a much shorter time and with less labor than the work of resetting the dimming rate of 10 lighting devices each time. The scene setting may be included as a function of the application that operates the control device, but it is not always defined by the name of "scene". Further, as the setting of each scene, the scenes of groups 1 and 2 may be set as follows. Here, the group 1 may be composed of, for example, 10 base lights, and the group 2 may be composed of another 10 base lights. Then, for example, in scene 1, group 1: dimming rate 0% and group 2: dimming rate 50% may be set, and in scene 2, group 1: dimming rate 50%, group 2: dimming rate may be set. The rate may be set to 0%. By setting the scene in this way, it is possible to instantly exchange a zone where workers can easily concentrate and a zone where workers can easily relax and communicate with other workers, and when the scales of the two zones are different. In addition, the scale of each zone can be changed instantly according to needs. Regarding dimming and toning control of a plurality of devices in a scene, that is, group control, signal delay is allowed, and variation in device operation is also allowed. For example, the permissible variation in device operation is within 30 minutes, more preferably within 10 minutes, even more preferably within 1 minute, most preferably within 10 seconds, and a signal or signal that falls within this range. The instruction delay is included in the behavior of multiple devices that are scened.

<Concentrated space>
The concentrated space may be defined as follows. Specifically, when two or more desks having a work surface where the illuminance of the task light is larger than the illuminance of the base light are arranged so as to be adjacent to each other, the above two or more desks are arranged on a plane including the vertical direction. When we consider an arbitrary plane that intersects at least one desk, if that plane intersects at least one side of the two or more desks and the two or more desks intersect with another desk, the above 2 One desk included in the above desk and facing the other desk via a plane is specified.

A region that looks like a line when viewed from above in the vertical direction) may be defined as the concentrated space.

<Non-concentrated space (relaxing space, co-creation space)>
The decentralized space may be defined as follows. Specifically, when two or more desks having a work surface whose illuminance of the task light is smaller than the illuminance of the base light are arranged so as to be adjacent to each other in succession, the above two or more desks are arranged on a plane including the vertical direction. When we consider an arbitrary plane that intersects at least one desk, if that plane intersects at least one side of the two or more desks and the two or more desks intersect with another desk, the above 2 One desk included in the above desk and facing the other desk via a plane is specified. Then, the one is more than the center of the other desk-side end of the one desk where the planes intersect and the desk-side end of the one desk where the planes intersect.

(Specific control that can achieve the purpose of the present disclosure)
This item describes an example of specific control that can flexibly and quickly allocate the centralized and decentralized work space control area so as to meet the needs of the centralized and decentralized work space control area. FIG. 5 is a flowchart for explaining an example of control for expanding or reducing the centralized work space control area and at the same time reducing or expanding the decentralized work space control area based on human needs. FIG. 5 is a flowchart for explaining switching control between scene 1 and scene 2 (see FIG. 2) executed by the device 61 based on human needs.

With reference to FIG. 5, when the environmental control system 10 is installed in the ABW office 20 and its operation starts, the control starts, and in step S1, the control device 61 reproduces the scene 1. Dimming and toning control of the base light 3 and the task light 5. After that, in step S2, the control device 61 has (the number of dice sensors whose surface desired for the centralized control mode is directed upward) / (desk having a work surface included in the centralized work space control area). It is determined whether or not (the number of) is equal to or less than the first predetermined value. The number of desks may be set by the user in advance in the control device 61 or the calculation unit, or may be automatically counted by sensing or the like and stored in the control device 61 or the calculation unit. Good.

Here, the control device 61 specifies (the number of dice sensors whose surface desired for the centralized control mode is directed upward) / (the number of desks having work surfaces included in the centralized work space control area). It is an example of the first person occupancy amount, and the first predetermined value is an example of the first person occupancy threshold. Further, the first predetermined value can be set to, for example, 4/14 = 2/7 or 3/14 in the case of the first embodiment in which the number of all dice sensors included in the environmental control system 10 is 14. ..

The first person occupancy uses the number of desks whose work surface is included in the centralized work space control area and the work surface located in the centralized work space control area specified based on the information from the sensor device. Any value may be used as long as it is calculated based on the number of people who are considered to be working. For example, (the number of desks having a work surface included in the centralized work space control area) / (centralized control mode). The number of dice sensors whose desired surface is directed upward) or the like.

If a negative determination is made in step S2 and the control device 61 determines that the need for the centralized work space is high, the control becomes a return and steps S1 and subsequent steps are repeated. On the other hand, if an affirmative determination is made in step S2, the process proceeds to step S3, and the control device 61 is asked to (the number of dice sensors whose surface desired for the decentralized control mode is directed upward) / (for decentralized work). It is determined whether or not the number of desks having a work surface included in the space control area) is equal to or less than the second predetermined value. Here, the control device 61 specifies (the number of dice sensors whose surface desired for the decentralized control mode is directed upward) / (the number of desks having work surfaces included in the decentralized work space control area). Is an example of the second person occupancy amount, and the second predetermined value is an example of the second person occupancy threshold value. Further, in the case of the first embodiment, the second predetermined value can be set to, for example, 3/14 = 2/7 or 2/14 = 1/7.

The second person occupancy is the number of desks whose work surface is included in the decentralized work space control area and the work surface located in the decentralized work space control area specified based on the information from the sensor device. Any value may be used as long as it is calculated based on the number of people who are considered to be using the above, for example, (the number of desks having a work surface included in the space control area for decentralized work) / (. The number of dice sensors with the desired surface facing the decentralized control mode facing upward) may be used.

When the affirmative judgment is made in step S3 and the control device 61 determines that the need for the decentralized work space is low, the control device 61 determines that the scene does not need to be changed, and the control returns. Step S1 and below are repeated. On the other hand, if a negative determination is made in step S3, the process proceeds to step S4, and the control device 61 determines that the range of the space control area for decentralized work is insufficient for the demand of the decentralized control mode, and the scene Switch 1 to scene 2. As shown in FIG. 2, in the scene 1, the desk group 1 having eight work desks D07 to D14 is a concentrated space, while the desk group 1 having six work desks D01 to D06 is a non-concentrated space. It has become. On the contrary, in the scene 2, the desk group 1 having eight work desks D07 to D14 is a non-concentrated space, while the desk group 1 having six work desks D01 to D06 is a concentrated space. It has become. From this, by switching the scene 1 to the scene 2, the space control area for decentralized work can be expanded and at the same time the space control area for centralized work can be reduced, and it is possible to flexibly and quickly respond to human needs.

In step S5 after step S4, the control device 61 is a desk having (the number of dice sensors whose surface desired for the centralized control mode is directed upward) / (the work surface included in the centralized work space control area). (Number of) is higher than the first predetermined value. If a negative determination is made in step S5, the control device 61 determines that there is not much demand for the concentrated space, returns to step S4 to maintain the reproduction of the scene 2, and repeats steps S4 and subsequent steps.

On the other hand, if an affirmative determination is made in step S5, the process proceeds to step S6, and the control device 61 is asked to (the number of dice sensors whose surface desired for the decentralized control mode is directed upward) / (decentralized work). It is determined whether or not the number of desks having a work surface included in the space control area) is higher than the second predetermined value. If an affirmative judgment is made in step S6, it is determined that the disadvantage of the person using the non-concentrated space will increase when switching to scene 1, and the process returns to step S4 to maintain the reproduction of scene 2 and step S4. The following is repeated. On the other hand, if a negative determination is made in step S6, the control becomes a return, and steps S1 and subsequent steps are repeated.

(Structure and action of Example 1)
The control in the environmental control system 10 of the first embodiment and the specific aspects of each configuration have been described above. In this item, the essential configuration of the environmental control system 10 and its action / effect, and the configuration preferable to be adopted and its action / effect will be described.

<Indispensable configuration and the action and effect derived from that configuration>
The environment control system 10 has a plurality of task lights 5 for illuminating the work surface (upper surface) of the work desks D01 to D14 in the ABW office (room) 20 in which the plurality of work desks (desks) D01 to D14 are arranged. A plurality of base lights 3 for illuminating a wider area than the work surface in the ABW office 20, position information of one or more people existing in the ABW office 20, and 1 existing in the ABW office 20. A dice sensor that detects at least one of the above-mentioned person's location information, the presence information of one or more people existing in the ABW office 20, and the personal information of one or more people existing in the ABW office 20 room. Sensor devices) S1 to S14 and a control device 61. Further, the control device 61 includes a centralized work space control area in which the illuminance of the task light 5 is larger than the illuminance of the base light 3 and a decentralized work space control area in which the illuminance of the task light 5 is smaller than the illuminance of the base light 3. Zoning control is performed to control dimming and toning of the plurality of task lights 5 and the plurality of front base lights 3 so as to generate the above. Further, the environment control system 10 determines that the control device 61 determines that the amount of the centralized work space control area is small (the area of the centralized work space control area is narrow) based on the information from the dice sensors S1 to S14. Dimming and toning control of a plurality of task lights 5 and a plurality of base lights 3 so that the amount of the centralized work space control area is large (the area of the centralized work space control area is wide), and a control device. When the 61 determines that the amount of the centralized work space control area is large (the area of the centralized work space control area is wide) based on the information from the dice sensors S1 to S14, the amount of the centralized work space control area is small. The plurality of task lights 5 and the plurality of base lights 3 are dimmed and toned so as to be (the area of the space control area for centralized work is narrow), and the control device 61 is from the dice sensors S1 to S14. If it is determined based on the information that the amount of the decentralized work space control area is small (the size of the decentralized work space control area is narrow), the amount of the decentralized work space control area is large (the decentralized work space). Dimming and toning control of the plurality of task lights 5 and the plurality of base lights 3 so that the control area is wide), and the control device 61 is not based on the information from the dice sensors S1 to S14. When it is judged that the amount of the centralized work space control area is large (the area of the decentralized work space control area is wide), the amount of the decentralized work space control area is small (the size of the decentralized work space control area is large). One or more of dimming and toning control of the plurality of task lights 5 and the plurality of base lights 3 are executed so as to be narrow). Here, "quantity" can be defined as a physical quantity whose magnitude relationship can be defined, and this physical quantity can be defined to include a dimensionless quantity such as a number. Therefore, the "quantity" includes, for example, "area (area)" and "number".

According to the present disclosure, at least one of the centralized work space control area and the decentralized work space control area is based on the needs of use of at least one of the centralized work space control area and the decentralized work space control area. One can be enlarged or reduced. Therefore, it is possible to realize active zoning that easily responds to the fluid work performance of workers and organizations and the needs for each space that occur in cycles such as hourly, daily, and monthly.

<Multiple configurations that are preferable to select and the effects derived from each configuration>
In the environmental control system 10, the area of the centralized work space control area may be widened, and at the same time, the area of the decentralized work space control area may be narrowed. At the same time as controlling to narrow the area of the space control area for decentralized work, control may be performed to increase the area of the space control area for decentralized work. The term "simultaneous" is preferably 30 minutes or less, more preferably 10 minutes or less, further preferably 1 minute or less, and most preferably 10 seconds or less. This is because if it is within 30 minutes, the layout change can be achieved sufficiently quickly and with less labor than the layout change that involves the transportation and re-installation of general furniture and furniture. Further, this configuration is not an essential configuration and does not have to be executed. For example, by using the method described in detail above, the amount of the centralized work space control area is increased (centralized work space control area). Only the control to reduce the amount of the centralized work space control area may be performed, or only the control to reduce the amount of the centralized work space control area may be performed. .. Alternatively, only the control for increasing the amount of the decentralized work space control area (widening the decentralized work space control area) may be performed by using the method described in detail above, and the non-centralized work space control area may be increased. Only control may be performed to reduce the amount of the centralized work space control area (narrow the size of the decentralized work space control area), that is, for example, to increase the amount of the centralized work space control area. Only the control to reduce the amount is performed, and the control to change the amount of the space control area for decentralized work does not have to be performed. On the contrary, the control to increase or decrease the amount of the space control area for decentralized work is performed. It is not necessary to control the amount of the space control area for intensive work.

According to this configuration, it is possible to effectively distribute the space control area for centralized work and the space control area for decentralized work when the size of the room is small.

Further, the control device 61 is located within the centralized work space control area specified based on the number of work desks D01 to D14 whose work surface is included in the centralized work space control area and the information from the dice sensors S1 to S14. By comparing the first person occupancy amount calculated based on the number of people who are considered to be using the work surface to be performed with the first person occupancy threshold, the amount of the space control area for intensive work (for intensive work). Based on the determination of whether or not the space control area is appropriate, the number of work desks D01 to D14 whose work surface is included in the decentralized work space control area, and the information from the dice sensors S1 to S14. Comparing the second person occupancy amount calculated based on the number of people who are considered to be using the work surface located in the specified decentralized work space control area with the second person occupancy threshold. Then, the amount of the space control area for decentralized work (the size of the space control area for decentralized work) is adjusted based on the calculation result information of the calculation unit 61c that performs at least one of determining whether or not it is appropriate. Light / toning control may be executed.

According to this configuration, at least one of the needs of the centralized work space control area and the needs of the decentralized work space control area can be objectively determined.

[Example 2]
In the first embodiment, the case where the dice sensors S1 to S14 are used to switch the scene in a responsive manner to the needs of a person has been described, but the scene may be switched only for a predetermined period. For example, in an office or the like, the lighting may be dimmed during lunch break, but the scenes in the morning and after lunch break to 4:00 pm are switched when the task light 5 and base light 3 are turned on after lunch break. It may be the one that can be used. In this case, for example, each person who uses the ABW office 20 from the afternoon directly controls the dimming and toning of the desired information of the mode from the afternoon in the morning by some method described in the section of the sensor device described above. It is transmitted to a control device or other information device, for example, an operation terminal composed of a tablet, a smartphone, etc., a workstation or a server on the cloud, and receives a signal directly from the sensor device, or a signal from the information device. The receiving control device may select the optimum scene based on the information. Although it will be described repeatedly just in case, in the first embodiment, the mode in which the control device executes the calculation and determination of the needs of the office space is shown, but it is not essential in the configuration intended by the present application. That is, although not particularly illustrated, it is obvious that the part that executes this calculation or determination may be, for example, a cloud server having a CPU, another personal computer, or a tablet, and any mode can be selected.

Further, in the first embodiment, the zoning is executed only by the dimming / coloring control of the task light 5 and the base light 3, but the zoning is performed in addition to the dimming / coloring control of the task light 5 and the base light 3. It may also be executed as a sound output.

In the second embodiment, the case where the scene is switched only for a predetermined period and the zoning is performed by using the sound effect will be described.

FIG. 6 is a layout layout diagram corresponding to FIG. 1 in the environmental control system 110 of the second embodiment. Further, FIG. 7 is a block diagram corresponding to FIG. 3 in the environmental control system 110 of the second embodiment. As shown in FIG. 6, the environmental control system 110 is different from the environmental control system 10 of the first embodiment in that a plurality of speakers 109 (for example, LSPX-103E26: Sony) are attached to the duct rail 104. Further, instead of using the dice sensors S1 to S14 as the sensor device, an information reading device 88 that reads a desired mode registered in advance in the mobile phone (smart phone) is adopted. The information reading device 88 is installed, for example, around the doorway of the ABW office 120.

Further, as shown in FIG. 7, in the second embodiment, the control device 161 of the environmental control system 110 includes the control unit 161a, the dimming and toning signal transmission unit 161b, the calculation unit 161c, and the sound signal transmission unit 161d. And outputs a signal including sound information to be output to a plurality of speakers 109. Unlike the case shown in FIG. 7, the sound control unit of the environment control system 110 is attached to an external information device (for example, an operation terminal or a workstation or server on the cloud) of the control device 161 that directly performs dimming / coloring control. It may be built in, and more specifically, it may be built in, for example, a personal computer, a tablet, a smartphone, a single board computer, or the like.

More specifically, the sound effects of the plurality of speakers 109 will be described. As shown in FIG. 6, in the environmental control system 110, four first to fourth speakers 109a to 109d are attached to the duct rail 104, and the respective speakers 109a to 109a are described. The 109d was wirelessly connected in stereo. Further, the first speaker 109a and the second speaker 109b form the speaker group 1, and the third speaker 109c and the fourth speaker 109d form the speaker group 2. Then, the first and second speakers 109a and 109b belonging to the speaker group 1 output the same first audio content, and the third and fourth speakers 109c and 109d belonging to the speaker group 2 output the same second audio content. Is output. The first and second speakers 109a and 109b belonging to the speaker group 1 output sound to a person existing in the area of the desk group 1, and the third and fourth speakers 109c and 109d belonging to the speaker group 2 output the sound to the person existing in the area of the desk group 1. Outputs sound to people in the area of group 2. The number of speakers belonging to the speaker group 1 may be any number, and the number of speakers belonging to the speaker group 2 may be any number. Further, as the speaker 109, a directional speaker, for example, a parametric speaker or the like may be adopted. Since ultrasonic waves are used in parametric speakers, it is possible to give remarkable directivity to the sound output direction.

With this configuration, for example, sound content recorded from the babbling sound of a stream was played back from a speaker group 1 at the top of the desk group 1 via a smartphone. At the same time, the sound content recorded with jazz and bossa nova music was played back from the speaker group 2 at the top of the desk group 2 via a smartphone different from the above. Here, when I was seated at a desk belonging to Desk Group 1, I could hear the babbling sound of a stream, and I could only hear a little jazz and bossa nova music. On the other hand, when I was seated at the desk belonging to Desk Group 2, I could hear jazz bossa nova music, and I could only hear the babbling sound of the stream. From the above, it was confirmed that, for example, with such a configuration, different contents can be selectively provided to some extent in different desk group units.

Further, in the second embodiment, the scene setting shown in FIG. 8 is performed, and in addition to the sound output from the speaker groups 1 and 2, the task light 5 and the base light 3 are dimmed and toned, respectively. The scene was played back. The sound information output by each lighting device in each scene is stored in the storage unit 161e in advance. For example, when the above-mentioned scene 1 is reproduced as lighting control in addition to the sound output from the speaker groups 1 and 2, the desk group 1 is provided with the efficiency of the concentrated work by the lighting described in the scene 1 in the first embodiment. The effect that is easy to increase and the effect that is easy to increase the efficiency of concentrated work due to the murmuring sound of the stream are superimposed. Therefore, due to the synergistic effect of the superposition, the zone of the desk group 1 can be changed to an area where the efficiency of the concentrated work can be easily increased.

The babbling sound of a stream is close to the characteristics of so-called white noise and brown noise, which have intensity in the entire frequency range. This characteristic is a graph of the Fourier transform spectrum that does not have intensity in the entire frequency domain when expressed graphically as the Fourier transform spectrum of frequency vs. intensity, for example, the Fourier transform spectrum of frequency vs. intensity of a specific pitch sound of a piano. In comparison with the graph of, it can be mentioned that the frequency characteristic of the sound in the graph is broad. Strictly speaking, in zoning control, the spectral width in the fast Fourier transform of the sound output at the maximum volume in the centralized work space control area is output at the maximum volume in the decentralized work space control area. It may be wider than the spectral width in the fast Fourier transform of the sound being played. Here, the spectral width refers to the wavelength or frequency spread width of the spectral line, and the intensity is reduced to a predetermined width (for example, 1/2, 1/10, etc.) with respect to the maximum value. It is the difference in wavelength between two wavelengths and may be expressed in frequency. The spectral width may be defined as the full width at half maximum of the spectrum (the width of the wavelength at which the relative radiant intensity is 50% of the peak value in the spectral distribution of the optical output). Sounds with this characteristic are noises that can reduce the efficiency of concentrated work that has various frequencies and is outpatient from a place other than desk group 1, as compared to sounds that tend to have no intensity in the frequency domain, for example. It has a remarkable effect of easily canceling noise, speaking voice, and the like. Therefore, workers working in desk group 1 are less likely to hear external noise. Therefore, the zone of the desk group 1 can be made into an area where the worker can easily concentrate on the work and can easily concentrate on the work.

As sound content that can improve the efficiency of concentrated work, content close to the above-mentioned characteristics called white noise and brown noise is preferable, but this is not particularly limited. For example, it may be mainly composed of natural environment sounds such as the chirping sound of a small bird, the rubbing sound of forest leaves, and the sound of waves in the sea, or it is music composed mainly of electronic sounds whose waveforms are synthesized by a music synthesizer or the like. Is also good. The sound content may be a recording of natural sounds as it is, a composition by a human being, or a composition by a computer algorithm, AI, or artificial intelligence. The sound content may be a mixture of the above various sounds.

On the other hand, in the existing area of the desk group 2, the scene 1 is reproduced in addition to the output of the sound content recorded with the music of jazz or bossa nova. Therefore, as described in the first embodiment, the color temperature is high. The effect of relaxing and facilitating smooth communication by multiple people based on low illumination light and the effect of facilitating relaxing and smooth communication by multiple people due to jazz and bossa nova music will be superimposed. .. Therefore, due to the synergistic effect of the superposition, the zone of the desk group 2 can be made into an area where the worker can relax at each stage and smooth communication between a plurality of people can be easily planned at each stage.

Compared to the above-mentioned white noise and brown noise, jazz bossa nova music has a characteristic that the frequency characteristic of sound in the graph of the Fourier transform spectrum of frequency vs. intensity is not broad. This is because instruments such as piano, saxophone, and bass, which mainly play jazz and bossa nova, play a specific single scale, that is, de re mi fa so la si do and its chromatic scale. This is due to the fact that it is used in a state where it is strictly tuned to output. Therefore, the noise canceling function for the above-mentioned external noise tends to be poor, but the need for the noise canceling function is weak in the co-creation space intended to relax and communicate with multiple people in the first place. However, even if the noise canceling function is poor, no major adverse effect will occur.

Furthermore, jazz and bossa nova are preferred sound contents in cafes and relaxation facilities, and are frequently used to promote relaxation and smooth communication among multiple people. Therefore, as is clear from this, by using these sound contents, the worker can feel a sense of relaxation and comfort, and smooth communication can be realized.

It is preferable to adopt sound contents having characteristics similar to those called jazz or bossa nova as sound contents that can promote a feeling of relaxation and smooth communication by a plurality of people, but this is not particularly limited. For example, classical music, healing music, natural environment sounds, and the like may be adopted as sound contents that can promote a feeling of relaxation and smooth communication by a plurality of people. Such sound content may be a recording of natural sounds as it is, a composition by a human being, or a composition by a computer algorithm, AI, or artificial intelligence. The sound content may be a mixture of the above various sounds.

As is clear from the above description, it is preferable that the lighting control and the sound control are linked, and it is more preferable that the purpose of the lighting and the sound content that can be provided dominantly to each desk group is the same. By doing so, it is possible to create a synergistic effect by superimposing the effects of the purpose intended by each desk group, and to make the effect of the purpose intended by each desk group remarkable.

When the lighting control and the sound control are linked, the operations do not have to be strictly synchronized. For example, the start time or the end time of the lighting scene switching and the start time or the end time of the sound content switching are determined. Even if there is a slight deviation, the above-mentioned effects are not lost. Further, in the case where such a deviation occurs, the deviation time between the start time or the end time of the lighting scene switching and the start time or the end time of the sound content switching may be any time, but within 30 minutes. It is preferably within 10 minutes, more preferably within 1 minute, and most preferably within 10 seconds. When the deviation time is within 30 minutes, the layout change can be achieved sufficiently quickly and with less labor than the layout change involving the transportation and re-installation of general furniture and furniture.

<Evaluation result of illuminance and volume of space in scene 1>
Next, one test result of the illuminance and volume of the space in the scene 1 will be described. FIG. 9 shows information on the irradiation light emitted by the lighting devices 3 and 5 when the sound is output and the scene 1 is reproduced in the second embodiment, and the sound output by the speakers 109a to 109d. It is a schematic diagram explaining with the information of. Further, FIG. 10 shows an illuminance meter (CL-200: Konica Minolta) and a sound level meter arranged so as to cross the work desks D12 to D03 while playing back the scene 1 in the ABW office 120 of the second embodiment. It is a graph which shows the result of one test example when the illuminance and volume of a space were measured by (SD-2200: FUSO). In FIG. 10, y1 is a function related to illuminance, and y2 is a function related to volume.

As shown in FIG. 10, in this test example, the illuminance and the volume are the lowest with respect to the passage provided between the desk group 1 and the desk group 2. Then, different illumination lights and different sound contents are reproduced on both sides of the passage. Further, in the desk group 1, it is possible to realize the illumination light in which the illuminance locally and rapidly increases on the desk surface. Furthermore, in the desk group 1, the sound content that promotes the concentration of people is reproduced at a loud volume, and in the desk group 2, the sound content that gives a feeling of relaxation and comfort to the person is output in the desk group 1. It is output at about half the volume. From this, in this test example, the peripheral area of the desk group 1 and the peripheral area of the desk group 2 can be clearly separated (divided), and excellent zoning can be realized. In addition, the peripheral area of the desk group 1 and the peripheral area of the desk group 2 are reproduced by the illumination light and the sound content, respectively, so that the peripheral area of the desk group 1 can be easily concentrated by a person. On the other hand, the area around the desk group 2 can be made into an excellent co-creation space where people can feel particularly relaxed and multiple people can communicate with each other.

It should be noted that the sound output of the present disclosure does not provide the person with favorite music and improve the performance of the person, and the sound should not be provided to the person by using earphones or headphones. This is because even if sound is provided to a person using earphones or headphones, the area cannot be divided.

Next, the timing of changing the scene in the second embodiment will be described. In the second embodiment, each person who uses the ABW office 120 at a specific date and time (for example, Thursday afternoon) wants to set the mode at the specific date and time, that is, the setting of the intensive work space, the setting of the non-intensive work. Use the application of your own operation terminal (for example, a mobile phone such as a tablet or smartphone) in advance to set one of the three options that do not set the space or set any mode. Set to. Then, by bringing the operation terminal closer to the information reading device 88 before the specific date and time, the information reading device 88 wants the information to identify the person, the selected mode, and the desired mode. The information on the date and time of is read and transmitted to the control device 161 in a state in which the information is linked.

Further, based on the information, the control device 161 is set to immediately before the specific date and time (for example, if the specific date and time is Thursday afternoon, the immediately before the specific date and time is Thursday morning). (Number of people who want a centralized control mode) / (Number of desks with work surfaces included in the centralized work space control area) and (Number of people who want a decentralized control mode) / (Non-centralized control mode) Calculate the number of desks with work surfaces included in the centralized work space control area).

Then, it is determined whether or not (the number of people who desire the centralized control mode) / (the number of desks having a work surface included in the centralized work space control area) is equal to or greater than the third predetermined value, and ( It has come to be judged whether or not (the number of people who desire the decentralized control mode) / (the number of desks having a work surface included in the decentralized work space control area) is equal to or more than the fourth predetermined value. There is.

Then, (the number of people who desire the centralized control mode) / (the number of desks having a work surface included in the centralized work space control area) is equal to or higher than the third predetermined value, and (the decentralized control mode is desired). When (the number of people doing) / (the number of desks with work surfaces included in the space control area for decentralized work) is less than the fourth predetermined value, scene 1 is reproduced at a specific date and time. It has become.

Further, (the number of people who desire the centralized control mode) / (the number of desks having a work surface included in the centralized work space control area) is less than the third predetermined value, and (the decentralized control mode is desired). When (the number of people doing) / (the number of desks with work surfaces included in the space control area for decentralized work) is equal to or greater than the fourth predetermined value, scene 2 is reproduced at a specific date and time. It has become.

Further, (the number of people who desire the centralized control mode) / (the number of desks having a work surface included in the centralized work space control area) is less than the third predetermined value, and (the decentralized control mode is desired). When (the number of people doing) / (the number of desks having a work surface included in the space control area for decentralized work) is less than the fourth predetermined value, scene 1 is reproduced (scene 2 may be reproduced). It has become like.

Further, (the number of people who desire the centralized control mode) / (the number of desks having a work surface included in the centralized work space control area) is equal to or higher than the third predetermined value, and (the decentralized control mode is desired). When (the number of people doing) / (the number of desks having a work surface included in the space control area for decentralized work) is equal to or greater than the fourth predetermined value, the number of people who desire the centralized control mode is Scene 1 is reproduced when there are more people who want the decentralized control mode, and conversely, the number of people who want the centralized control mode is the people who want the decentralized control mode. If it is less than the number of, scene 2 is reproduced.

In the second embodiment, by controlling the reproduction of the scene in this way, it is possible to realize active zoning that can appropriately meet the fluid work performance of workers and organizations and the needs for each space at a specific date and time in the future.

Note that (the number of people who desire the centralized control mode) / (the number of desks having a work surface included in the centralized work space control area) is an example of the first demand amount, and the third predetermined value is , Is an example of the first demand threshold. Further, (the number of people who desire the decentralized control mode) / (the number of desks having a work surface included in the decentralized work space control area) is an example of the second demand amount, and is the fourth predetermined value. The value is an example of the second demand threshold.

In addition, as the first demand amount, we want to use the number of desks whose work surface exists in the centralized work space control area and the work surface located in the centralized work space control area specified based on the information from the sensor device. Any value may be used as long as it is calculated based on the number of people. For example, (the number of desks having a work surface included in the centralized work space control area) / (person who desires the centralized control mode). The number of) etc. may be used. The second demand also includes the number of desks whose work surface exists in the decentralized work space control area and the work surface located in the decentralized work space control area specified based on the information from the sensor device. Any value may be used as long as it is calculated based on the number of people who want to use it. For example, (the number of desks having a work surface included in the space control area for decentralized work) / (decentralized control mode is desired). The number of people who are doing it) etc. may be used.

(Preferable configuration adopted in Example 2 and its action and effect)
As described above, in the environmental control system 110 of the second embodiment, the control device 161 is specified based on the number of desks whose work surface exists in the centralized work space control area and the information from the information reading device (sensor device) 88. By comparing the first demand amount calculated based on the number of people who want to use the work surface located in the centralized work space control area with the first demand threshold value, the amount of the centralized work space control area ( Determine whether the size of the centralized work space control area) is appropriate, identify the work surface based on the number of desks existing in the decentralized work space control area, and the information from the information reader 88. By comparing the second demand amount calculated based on the number of people who want to use the work surface located in the decentralized work space control area with the second demand threshold value, the decentralized work space control area can be obtained. Dimming / coloring control is executed based on the calculation result information of the calculation unit 161c that performs at least one of determining whether or not the amount (the size of the space control area for decentralized work) is appropriate.

Therefore, according to this configuration, at least one of the needs of the centralized work space control area and the nose of the decentralized work space control area can be objectively determined.

Further, the environmental control system 110 may further include a plurality of speakers 109 that output sound in the ABW office (room) 120. Further, in the zoning control, the plurality of speakers 109 may output sound to the centralized work space control area and the decentralized work space control area. In addition, the spectral width of the fast Fourier transform in the sound output at the maximum volume in the centralized work space control area is the fast Fourier transform in the sound output at the maximum volume in the decentralized work space control area. It may be wider than the spectral width in.

According to this configuration, the effect of easily increasing the efficiency of concentrated work by lighting and the effect of easily increasing the efficiency of concentrated work by sound can be superposed, and the synergistic effect of the superimposition creates a space control area for concentrated work. It is possible to change the efficiency of concentrated work to an area where it is easy to increase the efficiency of each step. Further, in the space control area for non-concentrated work, it is possible to superimpose the effect of easily enhancing the feeling of relaxation and communication by lighting and the effect of easily enhancing the feeling of relaxation and communication by sound. Therefore, due to the synergistic effect of the superposition, the space control area for non-concentrated work can be changed to an area where a feeling of relaxation can be easily felt and communication can be performed much easily.

Further, one or more speakers that output sound may be further provided in the room, and at least one of the volume of the speaker and the content output by the speaker may be controlled based on the calculation result information of the calculation unit. Here, one or more speakers may be configured so that sound can be output to only one of the centralized work space control area and the decentralized work space control area, and the environmental control system includes a plurality of speakers. , A plurality of speakers may be configured to be able to output sound to both the centralized work space control area and the decentralized work space control area. As is clear from the above description, if the configuration of this modification is adopted, the difference in different regions can be emphasized by the sound output from the speaker.

(When the scene is not set in advance)
Note that, unlike the cases described in Examples 1 and 2, the scene may not be registered in advance in the storage unit of the control device. Then, the control device controls dimming / coloring of one or more task lights and one or more base lights individually based on the information from the sensor device, or dimming / coloring control control for each group. By doing so, the centralized work space control area and the decentralized work space control area may be generated flexibly with a higher degree of freedom.

(Regarding the number of centralized work space control areas and non-centralized work space control areas)
Further, in Examples 1 and 2, a case where the centralized work space control area is one and the decentralized work space control area is also one has been described. However, the centralized work space control area may be composed of two or more parts discretely arranged with each other, and the decentralized work space control area may also be composed of two or more parts discretely arranged with each other. May be done. Further, when both the centralized work space control area and the decentralized work space control area are composed of two or more discretely arranged parts, the centralized work space control area is combined with each other and is discrete. The number of parts arranged in the above and the number of parts arranged discretely while forming a space control area for decentralized work in combination may be the same number or different numbers from each other. Here, in the zoning of the present disclosure, it is preferable that the entire such portion (island) is collectively changed into a centralized work space control area or a decentralized work space control area. Further, in connection with this description, the techniques of the present disclosure include information on the sensor device, that is, position information of one or more people existing in the room, presence information of one or more people existing in the room, and indoors. Zoning is performed based on at least one of the personal information of one or more existing persons. Therefore, it goes without saying that the technique of the present disclosure does not include a technique of changing the work surface corresponding to each seat to a centralized work space control area or a decentralized work space control area at the will of the individual.
