Description

TECHNICAL FIELD This disclosure relates to environmental control systems.

ABW (Activity Based Working) offices are emerging as a result of work style reform. ABW offices are designed to handle the ever-changing types and amounts of work, as well as the workers' own emotions and feelings, such as when a worker wants to do concentrated work alone, when they want to work in a group, or when they want to take a break and relax. This is a type of office that improves the efficiency of worker and organizational performance by allowing workers to select spaces with different design objectives in response to their motivations and intentions. As an example of how to create spaces with different design purposes, there is known a method of creating spaces with the purpose of increasing the efficiency of concentrated work using fixtures and furniture and zoning them, as described in Patent Document 1, for example.

Japanese Patent Application Publication No. 2017-131572

Ideally, the zoning of an ABW office would be continuously changed according to the fluid work performance of workers and organizations and the needs of each space. For example, even after the aforementioned booth-type fixtures and furniture have been installed, the zoning can be changed by changing the arrangement and number of the booth-type fixtures and furniture in response to excess or deficiency in usage. However, the work performance of workers and organizations and their needs for each space can occur in cycles such as hourly, daily, and monthly, so tasks such as transporting and reinstalling fixtures and furniture, and storing them in warehouses are It is difficult to continuously implement the ABW office in terms of the time and labor involved, and there are issues with the flexibility of design changes as a means of realizing an ABW office.

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

In order to solve the above problems, an environmental control system according to the present disclosure includes a plurality of task lights for illuminating a work surface of a desk in a room where a plurality of desks are arranged, and an area wider than the work surface in the room. multiple base lights for illuminating the room, location information of one or more people in the room, presence information of one or more people in the room, and personal information of one or more people in the room. a sensor device that detects at least one of the above, and a control device, the control device includes a concentrated work space control area in which the illuminance of the task light is greater than the illuminance of the base light; Zoning control is performed to control the dimming and color toning of multiple task lights and multiple base lights so that a non-concentrated work space control area is created, and the control device performs zoning control based on information from the sensor device. If it is determined that the amount of the concentrated work space control area is small, the plurality of task lights and the plurality of base lights are dimmed and colored controlled so that the amount of the concentrated work space control area is increased; If it is determined that the amount of space control area for concentrated work is large based on information from the sensor device, dimming and color adjustment of multiple task lights and multiple base lights is performed to reduce the amount of space control area for concentrated work. and when the control device determines that the amount of the non-concentrated work space control area is small based on the information from the sensor device, it controls multiple task lights and multiple task lights so that the amount of the non-concentrated work space control area becomes large. When the control device determines that the amount of the non-concentrated work space control area is large based on the information from the sensor device, the amount of the non-concentrated work space control area is adjusted. One or more of the dimming and color toning control of the plurality of task lights and the plurality of base lights is performed so as to reduce the size of the task lights and the plurality of base lights.

In this specification, a concentrated work space control area is defined as a region where the illuminance of the task light is greater 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. defined as the sum of one or more working surfaces. In addition, the non-concentrated work space control area is defined as one or more areas where the illuminance of the task light is lower than the illuminance of the base light on multiple work surfaces at multiple desks installed in the room where the environmental control system is installed. is defined as the sum of the working surfaces of . Note that the sum of the work surfaces can be determined as the sum of areas using a scale such as a design drawing or a ruler, or can be determined as the sum of the numbers of work surfaces. These are the amounts of the concentrated work space control area or the non-concentrated work space control area. Furthermore, in this specification, a "quantity" may be defined as a physical quantity whose magnitude relationship can be defined, and this physical quantity may also be defined to include a dimensionless quantity such as the number of objects. Therefore, the "amount" includes, for example, "size (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 overview of control aimed at by the environmental control system of the present disclosure)
In Example 1, first, the purpose and outline of the control aimed at in the environmental control system of the present disclosure will be roughly explained. After that, a detailed explanation of each configuration of the environmental control system and a specific example of control that can realize the purpose will be explained.

FIG. 1 is a drawing showing an example of a possible layout of a plurality of work desks D01 to D14 in an ABW office 20 as an example of a room in which an environment control system 10 according to Example 1 of the present disclosure is installed. , the arrangement of the plurality of work desks D01 to D14 when viewed from above, and the arrangement of the base light 3, duct rail 4 for electricity supply, and task light 5 attached to the ceiling of the ABW office 20, are shown on the work desks D01 to D14 It is a layout arrangement diagram written in a form superimposed on the arrangement.

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 them. Twenty-eight LED dimming and color control type base lights (for example, NNLK41515+NNL4600EXDK9: Panasonic) were installed at equal intervals as ambient lighting for illumination, and three rows of duct rails 4 for power supply were installed in the vicinity. Specifically, a total of 14 work desks D01 to D14 are arranged in four cases, and three duct rails 4 for power supply are placed near three rows of work desks D01 to D14 among the four work desks D01 to D14. They were arranged so as to extend in a direction substantially parallel to the extending direction of the rows.

Furthermore, a total of 14 task lights 5 were installed on each duct rail 4. As the task light 5, an LED dimming type 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 made to correspond one-to-one, and each task light 5 illuminates the central part of the corresponding work desk D01 to D14. Adjusted the installation position and installation direction of Task Light 5.

In addition, the 28 base lights 3 and the 14 task lights 5 are equipped with a multi-manager (for example, NQ51101: Panasonic), an LS/PD signal conversion interface (for example, NK51111: Panasonic), and a PD/control device as an example of a control device. It was sequentially connected to an optical signal conversion interface (for example, NK51012: Panasonic) and a PiPit+separate cell controller A type (for example, NQ23171Z: Panasonic) via a dimming signal line. In addition, seven task lights 5 were paired with two PiPit+separate cell controllers A type.

Furthermore, dice sensors S1 to S14 were arranged on the work surface of each of the work desks D01 to D14. The dice sensors S1 to S14 are dice-shaped IoT devices having a substantially cubic shape like dice, and are "electronic dice" which are dice-shaped devices with an acceleration sensor and a wireless communication function. These dice sensors S1 to S14 are arranged on a work surface so that a worker can select a desired mode. Specifically, the six sides of each dice sensor S1 to S14 are a side that means that the space control area for concentrated work is voted (desired), and a side that means that the space control area for non-concentrated work is voted (desired). It includes a plane that means that it is selected, and a plane that means that it is neutral, which means that neither of these two spaces is selected.

Each of the dice sensors S1 to S14 uses a built-in acceleration sensor to detect which direction and how much the dice has rotated, and determine which side is facing upward. Then, each dice sensor S1 to S14 sends the results to a terminal including a calculation unit, such as the multi-manager, doublet, smartphone, personal computer, etc., through a wireless communication network built in the ABW office 20. Send to the operating terminal consisting of. Here, when using the ABW office 20, when leaving the seat after finishing work, the person is obligated to leave the seat with the dice sensors S1 to S14 facing upward. ing. From this, the multi-manager or operation terminal determines how many people are working using the work desks D01 to D14, and how many of the people working desire the concentrated work space control area. It is now possible to determine whether there are people working there and how many of them desire a space control area for deconcentrated work. A plurality of dice sensors (14 dice sensors in the first embodiment) S1 to S14 constitute a sensor device. Note that, as the wireless communication method for the dice sensors S1 to S14, a method based on the IEEE802.15.4 standard can be suitably adopted.

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

Here, setting of each scene can be easily performed using an operating terminal in which an existing scene setting application is installed, such as a smartphone, a tablet, or a remote control. Then, each scene was actually recreated. Specifically, when scene 1 was played back using the operation unit 64 (see Figure 3) after the blind curtains on the windows of ABW office 20 were completely closed, desk group 1 and desk group 2 were visually divided. . Subsequently, when other scenes such as scene 3 and scene 4 were sequentially reproduced using the operation unit 64 (see FIG. 3), each scene was switched in about a few seconds.

Desk group 1 in scene 1 had an uneven illuminance distribution in which the illuminance was high only in the center of the work desks D07 to D014, and the illuminance decreased as the distance from the center increased. In addition, the illuminance of the floor and walls around the work desk was low, giving the space a low sense of brightness. Furthermore, in desk group 1 of scene 1, the illuminance of the task light was greater 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 the work desk where the illuminance of the task light is higher than the illuminance of the base light is defined as the concentrated work space control area. When a person working using the work surface of each work desk D07 to D014 wants the work surface of the work desk D07 to D014 that he or she is using to become a concentrated work space control area, dice sensors S1 to S14 are used. A central work space is used to vote (desired).

On the other hand, in desk group 2 of scene 1, the illuminance of work desks D01 to D06 has a more uniform illuminance distribution compared to desk group 1, and the illuminance of the floors and walls around the work desk is also high, giving a high sense of brightness. It was space. In desk group 2 of scene 1, the illuminance of the task light was lower 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 the work desk where the illuminance of the task light is lower than the illuminance of the base light is defined as a non-concentrated work space control area. When a person working using the work surfaces of the work desks D07 to D014 wants the work surfaces of the work desks D07 to D014 that he or she is using to become a non-concentrated work space control area, the dice sensors S1 to S14 are used. It is a decentralized work space that is used to vote (desired).

At this time, when a worker is seated in desk group 1, the illuminance is high only in the center of work desks D07 to D014, which the worker should pay more attention to, reducing cognitive noise factors in peripheral vision. It is easier to immerse yourself in work and improve the efficiency of concentrated work. Furthermore, in this method, by setting the dimming rate of the base light 3 low, the visibility of peripheral vision such as walls and floors is reduced, so it is easier to concentrate on the work desks D07 to D014 and the work. Easy to increase effectiveness. Additionally, because the dimming rate of base light 3 is set low, workers working in desk group 1 may not be able to clearly see their facial expressions when other workers see them from the outside, or It is difficult to talk to him because his shadow makes him look moody. In other words, the worker working in this desk group 1 is likely to be talked to by other workers and the probability of work being interrupted is likely to decrease, and as a result, the efficiency of concentrated work is likely to be improved. From the above, when scene 1 is reproduced, desk group 1 is a space that easily functions as a concentration space. On the other hand, in Scene 1, Desk Group 2 has a low color temperature and facilitates relaxation and communication among multiple people, so it is a space that easily functions as a deconcentration space (relaxation space, co-creation space).

Desk group 1 and desk group 2 have significantly different spatial illuminance distributions. In particular, desk group 1 is characterized by lower illuminance around the work desk, such as the floor and walls, and this is a factor, giving a strong sense of spatial division between the two desk groups. Furthermore, since the color temperature of the lighting between desk group 1 and desk group 2 is significantly different, there is a strong sense of space division in appearance. From the above, it has a zoning effect that visually separates spaces without using fixtures or furniture. The greater the difference in illuminance distribution and color temperature between groups, the easier it is to enhance the zoning effect.

In addition, desk group 1 and desk group 2 differ in the work content they encourage workers to perform.For example, in this embodiment, desk group 1 encourages concentrated work, while desk group 2 encourages relaxation and communication, so it is only visually appealing. This effect also contributes to the zoning effect, as it also creates differences in how each space is used functionally.

When zoning is performed using this method, switching between each scene can be 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, if the number of desired concentrated work space control areas using each dice sensor S1 to S14 becomes relatively large due to circumstances such as a day when the need for a concentrated space is high, such as on a busy day in the office, each dice sensor The calculation unit that receives the signals from S1 to S14 determines that there is a high need for a concentrated work space, switches the scene from scene 1 to scene 3 via the multi-manager, and creates a concentrated work space in the ABW office 20. Increase the control area from 8 working planes to 14 working planes. Alternatively, if the number of desired concentrated work space control areas using each dice sensor S1 to S14 becomes relatively large, the operation terminal that receives the signal from each dice sensor S1 to S14 controls the concentrated work space. By controlling the multi-manager, the scene is switched from scene 1 to scene 3, and the central work space control area of ABW office 20 is increased from 8 work surfaces to 14 work surfaces. . In this way, by meeting the needs of workers for a concentrated space, it is easier to improve the work performance of workers and organizations as a result.

Alternatively, if a relatively large number of dice sensors S1 to S14 are required to create a non-concentrated working space due to circumstances such as a fallow day, a calculation unit that receives signals from each dice sensor S1 to S14 may be used. determined that there was a high need for a space control area for non-concentrated work, and switched the scene to scene 4 via the multi-manager, reducing the space control area for concentrated work in ABW office 20, while creating a space control area for non-concentration work. Increase the spatial control area from 8 work surfaces to 14 work surfaces. Alternatively, if the number of desired non-concentrated work spaces using each dice sensor S1 to S14 becomes relatively large, the operation terminal that receives the signal from each dice sensor S1 to S14 controls the non-concentrated work space. Judging that the area needs are high, the scene is switched to scene 4 through the multi-manager, and the concentrated work space control area of ABW office 20 is reduced, while the non-concentrated work space control area is changed to work surface 8. to 14 working surfaces. In this way, by reducing the space control area for concentrated work and increasing the space control area for non-concentration work to 14 work surfaces, it is possible to increase co-creation space, reduce stress in the organization, and improve communication. It has the effect of increasing the amount. Further, at this time, it is not necessary to immediately switch the scene by the control by the multi-manager or by the control by the multi-manager via the operating terminal. For example, after receiving a signal indicating such a worker's request, the scene change could be performed after the ABW office's lunch break or at the start of the next day's business hours. This is preferable because it is less likely to cause discomfort or discomfort due to environmental changes. Note that in the configurations mentioned so far, the receiving section and the calculating section that receive the signals from each of 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 section that receives signals from each of the dice sensors S1 to S14, a calculation section, and a multi-manager.

Furthermore, the control device learns (analyzes) the trends in the needs of the space control area for concentrated work and the trends in the needs of the space control area for non-concentrated work at each time of the week based on the information from the dice sensors S1 to S14. ) may be done. Then, a scene in which the control device identifies, for example, the needs of the concentrated and non-concentrated work space control area in the afternoon (or morning) of a predetermined day of the week (for example, Thursday) and realizes it based on the identified needs. may be selected.

According to this method, active zoning that changes the layout on an hourly, daily, monthly, or other cycle is possible, which is difficult with the method using fixtures and furniture as described above. In conventional office scenes, areas such as work desks and hallways are generally illuminated with highly uniform color temperature and illuminance distribution. In contrast, the present application uses a lighting method and control method that makes the color temperature and illuminance distribution non-uniform, so it can meet the needs of concentrated and deconcentrated work space control areas, especially in ABW office scenes. In this way, it is possible to flexibly and quickly allocate space control areas for concentrated and deconcentrated work, and achieve remarkable effects that could not be foreseen with conventional lighting knowledge.

(Detailed explanation of each configuration included in the environmental control system 10)
The purpose and outline of the control aimed at by the environmental control system 10 of the present disclosure have been described above. Next, each component included in the environmental control system 10 will be described in detail. FIG. 3 is a block diagram showing an example of the main configuration that can form 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 that includes dice sensors S1 to S14, a base light 3, a task light 5, and a multi-manager. includes a control section 61a, a dimming and color adjustment signal transmission section 61b, a calculation section 61c, and a storage section 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). Furthermore, 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 programs etc. stored in advance in the storage unit 61d. Furthermore, the nonvolatile memory stores in advance a control program, predetermined threshold values, and the like. Further, the volatile memory temporarily stores read programs and processing data. The storage unit 61d stores position information and device identification information regarding each of one or more task lights 5 and a plurality of base lights 3 that are set in advance. Further, the storage unit 61d stores data on light adjustment and color adjustment for reproducing the above-described scenes 1 to 4. In the first embodiment, eight work desks D07 to D014 belong to desk group 1, and six work desks D01 to D06 belong to desk group 2, but the work desks belonging to desk group 1 and desk group 2 The number of is not limited to the case of the first embodiment. Further, the number of lighting groups is not limited to three as in the first embodiment, and any number of lighting groups greater than or equal to two may exist. Next, position information, device identification information, and each configuration of the environmental control system 10 will be described in detail.

(About information)
<Location information>
Position information may be information similar to the absolute value of coordinates, such as the actual position in space, or relative positional relationship based on a certain task light, base light, or existing pillar in the space. information is also acceptable. Further, the position information stored in the storage unit 61d does not need 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) them. Furthermore, the position information may be recorded in the storage unit based on user input, or may be recorded using AI or computer algorithms. Further, the position information may be set and recorded by referring to drawing data stored in a separate storage unit or by being associated with the drawing data. Further, the position information does not need to be assigned to or associated with all devices included in the environmental control system, and may be selectable as appropriate depending on the user's circumstances.

<Device identification information>
The device identification information is information by which a device such as a spotlight or a base light can be identified, and includes, for example, a manufacturing number, a MAC address, an IP address, a product number, and the like. Device identification information is used when setting and recording the aforementioned location information, groups, and scenes, or when individually setting and recording output parameters (color toning rate, dimming rate, etc.) of each device. Used in a control system to prevent different devices from being unintentionally identified as the same. The device identification information does not need to be assigned or associated with all devices included in the environmental control system, and the devices to be assigned or associated can be selected as appropriate depending on the user's circumstances.

(Specific aspects of each configuration)
<Task light>
The device form of the task light is not particularly limited, and in addition to the above-mentioned spotlights, desk lights, downlights, etc. can be used as the task light. It is preferable that the light distribution be controlled such that the light is concentrated in the area, since it is easy to control the illumination range of the work desk. More specifically, a spotlight may have a structure in which the irradiation direction of the spotlight can be adjusted by applying an external force by a person, or by freely rotating two rotating shafts with a motor or the like using a remote control, the spotlight can be adjusted by applying an external force. It may be of a structure that allows the direction of irradiation of the light to be automatically adjusted to any downward direction. If at least one spotlight can change the emission direction of the illumination light in any direction at the installation position, it is possible to increase the degree of freedom in the gap between work desks in the longitudinal direction in the concentration space, and increase the width of the gap in the concentration space. The degree of freedom in the gaps between the work desks in the direction can be increased, and the degree of freedom in the layout of the concentration space can be increased. Furthermore, if at least one spotlight is of a type in which the direction of illumination of the spotlight can be freely adjusted using a remote control, the direction of illumination of the spotlight can be adjusted safely from the ground without using a stepladder or the like. More specifically, as described above, it is preferable to use a dimming and color control type spotlight as the task light.

The task light is lighting for increasing the efficiency of a worker's work, such as computer operation work, writing work, reading work, etc., and is lighting that selectively irradiates a viewing target area of a work desk. The visual target area is the area that can generally be seen when working at a work desk.For example, when operating a personal computer (hereinafter simply referred to as a computer) placed at the back of the center of the work desk. In this case, the center of the work desk is the center of the visual target area. At this time, we do not take into account changes in the visual object due to physiological factors or accidental changes in posture or line of sight.In other words, we do not take into account changes in the visual object due to physiological factors or accidental changes in posture or line of sight.In other words, we do not take into account changes in the visual object due to physiological factors or accidental changes in posture or line of sight. Events such as shifting one's gaze to the floor due to a cough or shifting one's gaze because someone is speaking to the user are not considered as significant changes in the visual target area at the work desks D01 to D14.

The illumination range of the task light is preferably limited to a part of the viewing target area, and for example, it is preferable that the illumination range covers 30% to 90% of the area of the work desk. Although the illumination range of the task light is not particularly limited, it is preferably approximately circular or polygonal. By doing this, the brightness of the viewing target area becomes brighter than the brightness of the area that is not the viewing target area, and cognitive noise in the peripheral visual field is reduced. Therefore, the worker's consciousness is directed toward the work desk, making it easier to improve work efficiency.

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

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

<Sensor device>
The sensor device can detect at least one of the following: location information of one or more people in the room, presence information of one or more people in the room, and personal information of one or more people in the room. Any device may be used. For example, in the first embodiment, a case will be described in which the sensor device is composed of a plurality of dice sensors, and one sensor device is attached to each of the chairs that exist in the same number as the work desks D01 to D14. A seating sensor (weight sensor) may be used, or a human sensor (optical sensor) that can detect whether or not a person is sitting on each chair may be used.

Alternatively, the sensor device may be a device that can identify the distribution of people in a room, or may be an LPS (Local Positioning System) (registered trademark), a camera, a LIDER, or the like that can detect position information of people. The LPS includes a beacon, a scanner, and a control device that are attached to a person (either carried directly by the person or attached to something the person carries) and transmit location information. A scanner installed on the ceiling receives signals from the beacon and measures location information. The control device specifies the distribution of people in the room by receiving the position information. The camera may be a camera system including a video analysis unit that analyzes the number of people and facial expressions based on captured video. The LPS may be an LPS system that includes a location information analysis unit that analyzes the number of people and the usage rate of space based on location information. Alternatively, the sensor device may be a device that measures indoor sound, or may be a microphone or the like. The microphone may be a microphone system that includes a voice analysis section that analyzes the number of people and their condition based on recorded voices either inside or outside the microphone body. It is preferable to use such a device as a sensor device because it makes it easier for the worker to automatically determine the control method for the control device without the worker having to perform any particular operation on any terminal.

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 determines, for example, the personal information of each worker, based on information from the ID information acquisition device, whether the worker is in a department that often uses a concentrated work space or a decentralized work space. You can decide which space you prefer.
Alternatively, after the ID information is detected, the desired mode may be stored wirelessly or wired in a cloud server or the like, so that the information can be learned. That is, learning may be performed through combined detection of ID information and other sensors, and the control device may automatically determine the space desired by the person who detected the ID information based on the learning.
ID information includes, for example, the identification number, identification symbol, name, gender, affiliated organization, schedule information, information on the terminal used for work, behavioral history, information on vital signs, and facility reservation information of the worker associated with the ID. , personnel information, and other office attribute information may be included, and this information may contribute to the control method of the control device.

Furthermore, the personal information includes information that declares (desires) each worker's desire for the control mode of the office space, such as a desire for a space control area for concentrated work or a desire for a space control area for non-concentrated work. An example of controlling only with personal information is to set the mode desired by the person in advance in an application on an operating terminal such as a smartphone, and then control the operating terminal with a detection device that detects that mode (in this case, A configuration may also be adopted in which the detection device reads a desired mode by bringing the detection device close to the sensor device (which becomes the sensor device), and the mode is transmitted to the control device. Alternatively, the sensor device may be an operation unit (consisting of an operation interface, etc.) that inputs a desired mode when entering the room. Then, when a person enters the room, he or she may be able to select a concentrated work space or a non-concentrated work space. Further, the personal information intended in this application includes anonymous information obtained through electronic dice, electronic voting systems, etc., in which the person who is the source of the declaration (desired) is not specified. In other words, the declaration (desired) and worker attribute information do not necessarily need 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/color adjustment control. Although the device form of the control device 61 is not particularly limited, for example, the lighting control device and the control application for the lighting control device described in Example 1 can be suitably adopted as the device form of the control device 61. In addition to the multi-manager shown in Figure 3, the device control application may also be installed on another terminal such as a tablet, computer, or smartphone. In this case, it is easier for the user to set up, manage, and operate the lighting control device. Therefore, it is preferable.

Specifically, in the example shown in FIG. 3, the control device 61, which is composed of, for example, a multi-manager, directly receives signals from the dice sensors S1 to S14. However, as shown in FIG. 4, for example, the control device 71 configured with a multi-manager may be configured to be controlled by receiving a signal from an operating terminal (eg, tablet, smartphone) 79. In this case, the operating terminal 79 may receive signals from the dice sensors S1 to S14, and may transmit a control signal to the control device 71 based on the received signals. Further, the operation terminal 79 may include the calculation section 73 and the operation section 75. That is, the control device 71 of the environmental control system 70 may be a terminal or device other than the operating terminal such as the tablet 72, or may be configured with a multi-manager or the like. Here, the control device 71 may have a casing embedded in a ceiling or wall surface, or may be placed on the ground, a storage shelf, or the like. Further, the control device 71 may be controlled by wired signal communication with an operating terminal such as the 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 communication signal line and a wireless LAN access point. Furthermore, at this time, the tablet 72 and the like do not need to communicate directly with the task light 5 and the base light 3. At this time, information on the positions and control conditions of the instruments that make up the environmental control system 70, such as mapping, scenes, groups, control schedules, etc., set using the operation unit 75 of the tablet 72 is transmitted to the control device 71, and The data may be recorded in the storage unit 76 of 71. In this case, even if the power of the tablet 72 is turned off or the tablet 72 is stored outside the communication range of the task light 5 or the base light 3, the intended environment control can be performed. Further, the control device 71 does not need to have a user interface for operation such as a liquid crystal display. In this case, the control device 71 is preferable because it can be easily miniaturized, and the ease of installation and design are improved. Although not particularly shown in FIG. 4, the operating terminal such as the tablet 72 may have a storage unit. The environmental control system 70 shown in FIG. 4 is a modification of the environmental control system 10 shown in FIG. It is clear that there are many systems.

<Calculation section>
The calculation unit includes a calculation process that determines the need for the amount of office space, for example, in this application, the proportion of the amount of concentrated work space or non-concentrated work space, based on the information obtained from the sensor device. As shown in FIG. 3, the calculation unit 61c may or may not be built into the control device 61, which is configured with, for example, a multi-manager and directly performs dimming and color adjustment control. As shown in FIG. 4, if it is not incorporated into the control device 71 that directly performs dimming and color toning control, it is installed in an information device other than the control device 71 that directly performs dimming and color toning control, e.g. , an operating terminal such as a smartphone, tablet, or personal computer, a server or workstation on the cloud, or an external storage medium. The arithmetic unit executes preprogrammed arithmetic processing, but the program may be rewritten during use. The program may be rewritten by a person using editor software or a personal computer, or it may be rewritten automatically by an AI or the like based on the learning results of past accumulated data. The arithmetic processing included in the arithmetic unit is not particularly limited in the scope of processing information obtained from a sensor device. Needs regarding the amount of office space can be determined by aggregating the number of people information obtained from systems and camera systems using four arithmetic operations, and by using statistical calculation methods such as regression analysis based on the above-mentioned aggregate information and past accumulated data. may be predicted. The calculation results obtained by the processing in the calculation unit are fed back to the control device, which is composed of, for example, a multi-manager and directly performs dimming and color adjustment control, and contributes to at least a part of the control method of the control device. This is preferable because it allows for flexible responses to the ever-changing conditions of the office. In addition, the calculation results of the calculation unit do not necessarily need to be fed back to the control device that directly performs dimming and color adjustment control; for example, they can be used to generate graphs of changes in the usage status of each space over time, or the performance of workers or organizations. Such information may also be output. This is particularly desirable for office managers and general affairs staff, as it makes it easier to understand how the office is being used and the performance of workers and organizations, which is normally difficult to keep track of.

<Dimmer color adjustment signal transmitter>
The light adjustment color signal transmitting unit 61b is a part that transmits a light adjustment color signal to the task light and the base light to execute at least one of light adjustment and color adjustment, and is included in the control device 61. be. The signal format is not particularly limited, and any format such as a known dimming signal, Wi-Fi, or BlueTooth (registered trademark) can be used. In addition, in the above-mentioned light adjustment color control, the light adjustment color adjustment control using the digital control method was explained, and the control method in which the digital signal (PDCL) was transmitted from the light control was explained. Here, in this control method, wiring of a signal line for digital control is required in addition to a power supply line. With this digital control, since detailed information can be communicated, control using a large amount of information can be performed, and control using wireless signals is also included in this method.

However, when performing the dimming color control, a phase control method may be adopted, or the dimming control may be executed by directly adjusting the power to the lighting equipment. This method directly controls the power supply current to the lighting equipment, so it is susceptible to voltage fluctuations, but it is easy to install because there is no need to run separate dedicated signal lines. Alternatively, when performing dimming and color control, a signal line method may be adopted, in which a dimming signal (duty signal) is sent from the light control, and the brightness of the light emitting part such as an LED is controlled by the power supply unit on the equipment side. May be controlled. This method requires wiring for a dimming signal line in addition to the power supply line, but it is less susceptible to the effects of wire voltage, allowing smooth dimming control without flickering. Note that control of only ON/OFF of the task light and base light is also included in dimming control.

<Storage section>
Any known device may be employed as the device constituting the storage section. Further, unlike the configuration shown in FIG. 3, the storage unit does not need to be built into the control device, and may be provided in an information device other than the control device that directly performs dimming and color adjustment control, such as a smartphone, for example. It may be configured with a tablet, a personal computer, etc., a server or workstation on the cloud, an external storage medium, etc. The storage unit is basically set by the user, but it can also be rewritten and set by a machine using the cloud or AI.

<Group information for multiple devices>
Group information for multiple lighting devices is managed, for example, by an app. Grouping may be set and saved by operating a tablet terminal, for example. The same command is sent to a plurality of grouped devices all at once, and, for example, similar dimming and color control is performed. Note that with regard to dimming and color adjustment control of a plurality of grouped devices, that is, group control, signal delays are allowed, and variations in the operation of the devices are also allowed. For example, an acceptable variation in equipment operation is within 30 minutes, more preferably within 10 minutes, even more preferably within 1 minute, and most preferably within 10 seconds, and signals falling within this range or Instruction delay is included in the behavior of multiple devices that are grouped together. It is preferable if the variation in the operation of the equipment is within the above-mentioned time period, because the layout change can be easily accomplished quickly and with less labor than a layout change that typically involves transporting and reinstalling fixtures and furniture. Group settings may be included as a function of an application that operates a control device, but are not necessarily defined under the name "group." It is preferable to set groups in an application that operates the control device or in a storage unit included in the control device because this makes it easier for the user to manage and change the lighting and its control parameters.

<Control scene information>
Setting and reproducing control parameters such as dimming rate and color toning rate for each of a plurality of lighting devices is a very complicated task for the user. This is because a typical ABW office uses 10 or more lighting devices, or 30 or more, and in many cases, 100 or more lighting devices. Therefore, a method is known in which control parameters for a plurality of lighting devices are collectively stored in a storage unit and managed, and this method is referred to as a scene in this application. By doing this, it is not only easier for the user to manage control parameter conditions for multiple lighting devices, but also it is possible to instantly reflect those conditions to multiple lighting devices at a desired timing (hereinafter referred to as This is preferable because it also facilitates regeneration (referred to as regeneration). Furthermore, by storing a plurality of types of scenes in the storage unit in advance, the user can instantly switch between two or more intended setting conditions. The settings for each scene may be set in any way depending on the specification needs. For example, unlike the example shown in FIG. The data may be stored in the storage unit, and the dimming rate of the ten base lights described above may be set to 30% in scene 2 and stored in the storage unit. Then, if you play scene 1, the dimming rate of the 10 base lights will instantly change to 100%, and if you play scene 2 from this state, the 10 base lights will instantly change to a state where the dimming rate is set to 100%. The light control rate may be set to 30%. This is preferable because it is possible to realize dimming control of a large number of lighting devices in a much shorter time and with less labor than resetting the dimming rate of 10 lighting devices each time. Note that scene settings may be included as a function of an application that operates the control device, but are not necessarily defined under the name "scene." Furthermore, each scene may be set for groups 1 and 2 as follows. Here, group 1 may be composed of, for example, 10 base lights, and group 2 may be composed of other 10 base lights. For example, in scene 1, group 1: dimming rate may be set to 0%, group 2: dimming rate may be set to 50%, and in scene 2, group 1: dimming rate is 50%, group 2: dimming rate. The rate may be set to 0%. By setting up the scene in this way, you can instantly switch between a zone where workers can easily concentrate and a zone where workers can relax and communicate with other workers, even if the two zones are of different sizes. In addition, the size of each zone can be changed instantaneously depending on needs. Note that with respect to lighting and color adjustment control of a plurality of scene-based devices, that is, group control, signal delay is allowed, and variations in the operation of the devices are also allowed. For example, an acceptable variation in equipment operation is within 30 minutes, more preferably within 10 minutes, even more preferably within 1 minute, and most preferably within 10 seconds, and signals falling within this range or Instruction delays are included in the behavior of multiple devices that are scened.

<Concentration space>
A focused space may be defined as follows. Specifically, if two or more desks with work surfaces on which the illuminance of the task light is greater than the illuminance of the base light are arranged consecutively next to each other, the illuminance of the two or more desks in a plane including the vertical direction is When considering any plane that intersects at least one desk, if that plane intersects with at least one side of the above two or more desks, and the above two or more desks intersect with another desk, then the above 2. One desk that is included in the above desks and faces the other desks via a plane is specified. and the center of the other desk side edge of said 1 desk with which the planes intersect and the desk side edge of said 1 of said other desk with which the planes intersect. A line segment area on the desk side (an area that looks like a line segment when viewed from above in the vertical direction) may be defined as the concentration space.

In addition, if two or more desks with work surfaces on which the illuminance of the task light is greater than the illuminance of the base light are arranged adjacent to each other, in a plane including the vertical direction, one of the two or more desks When considering any plane that intersects at least one desk in A place that is included in a desk and where the above-mentioned planes intersect, and is moved 1 m from the end of the two or more desks that does not intersect with the other desk. A line segment area on the desk side (an area that looks like a line segment when viewed from above in the vertical direction) may be defined as the concentration space.

In addition, desks with work surfaces where the illuminance of the task light is greater than the illuminance of the base light are not arranged consecutively next to each other, and desks with work surfaces where the illuminance of the task light is greater than the illuminance of the base light are is one and isolated, and if we consider any plane that intersects that one desk, that plane is at least on one side of the one desk, and on the other side of the one desk. If the plane intersects with the other desk, the end of the other desk on which the plane intersects, and the end of the desk on the other desk where the plane intersects. A line segment area closer to the desk than the center (an area that looks like a line segment when viewed from above in the vertical direction) may be defined as the concentration space.

In addition, desks with work surfaces where the illuminance of the task light is greater than the illuminance of the base light are not arranged consecutively next to each other, and desks with work surfaces where the illuminance of the task light is greater than the illuminance of the base light are is one and isolated, and if we consider any plane that intersects that one desk, that plane is at least on one side of the one desk, and on the other side of the one desk. If it does not intersect with the other desk, the line segment area ( An area that looks like a line segment when viewed from above in the vertical direction may be defined as the concentration space.

<Decentralized space (relaxation space, co-creation space)>
A decentralized space may be defined as follows. Specifically, if two or more desks with work surfaces where the illuminance of the task light is lower than the illuminance of the base light are arranged consecutively next to each other, the illuminance of the two or more desks in a plane including the vertical direction is When considering any plane that intersects at least one desk, if that plane intersects with at least one side of the above two or more desks, and the above two or more desks intersect with another desk, then the above 2. One desk that is included in the above desks and faces the other desks via a plane is specified. and the center of the other desk side edge of said 1 desk with which the planes intersect and the desk side edge of said 1 of said other desk with which the planes intersect. A line segment area on the desk side (an area that looks like a line segment when viewed from above in the vertical direction) may be defined as the non-concentrated space.

In addition, if two or more desks that have work surfaces where the illuminance of the task light is lower than the illuminance of the base light are arranged adjacent to each other, in a plane including the vertical direction, one of the two or more desks When considering any plane that intersects at least one desk in A place that is included in a desk and where the above-mentioned planes intersect, and is moved 1 m from the end of the two or more desks that does not intersect with the other desk. A line segment area on the desk side (an area that looks like a line segment when viewed from above in the vertical direction) may be defined as the non-concentrated space.

In addition, desks with work surfaces where the illuminance of the task light is lower than the illuminance of the base light are not arranged consecutively next to each other, and desks with work surfaces where the illuminance of the task light is lower than the illuminance of the base light are is one and isolated, and if we consider any plane that intersects that one desk, that plane is at least on one side of the one desk, and on the other side of the one desk. If the plane intersects with the other desk, the end of the other desk on which the plane intersects, and the end of the desk on the other desk where the plane intersects. A line segment area (an area that looks like a line segment when viewed from above in the vertical direction) closer to the one desk than the center of the area may be defined as the non-concentrated space.

In addition, desks with work surfaces where the illuminance of the task light is lower than the illuminance of the base light are not arranged consecutively next to each other, and desks with work surfaces where the illuminance of the task light is lower than the illuminance of the base light are is one and isolated, and if we consider any plane that intersects that one desk, that plane is at least on one side of the one desk, and on the other side of the one desk. If it does not intersect with the other desk, the line segment area ( An area that looks like a line segment when viewed from above in the vertical direction may be defined as the non-concentrated space.

(Specific controls that can achieve the purpose of this disclosure)
This item describes a specific example of control that can flexibly and quickly allocate concentrated and unconcentrated work space control areas to meet the needs of concentrated and unconcentrated work space control areas. FIG. 5 is a flowchart illustrating an example of control for expanding or decreasing the concentrated work space control area and simultaneously decreasing or expanding the non-concentrated work space control area based on human needs. 2 is a flowchart for explaining switching control between scene 1 and scene 2 (see FIG. 2) that the device 61 executes based on human needs.

Referring to FIG. 5, when the environmental control system 10 is installed in the ABW office 20 and its operation starts, control starts, and in step S1, the control device 61 performs the following steps so that scene 1 is reproduced. The base light 3 and the task light 5 are dimmed and toned. After that, the process moves to step S2, and the control device 61 executes the following steps: (the number of dice sensors whose faces for which the centralized control mode is desired are facing upward)/(the desk with the work surface included in the concentrated work space control area) ) is less than or equal to a first predetermined value. Note that the number of desks may be set in advance by the user by storing it in the control device 61 or the calculation section, or the number may be automatically counted by sensing or the like and stored in the control device 61 or the calculation section. good.

Here, the control device 61 specifies (the number of dice sensors whose surfaces for which the centralized control mode is desired are facing upward)/(the number of desks with work surfaces included in the concentrated work space control area). This is an example of the first person occupancy amount, and the first predetermined value is an example of the first person occupancy threshold. Further, 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 predetermined value can be set to, for example, 4/14=2/7 or 3/14. .

In addition, the first occupancy amount uses work surfaces whose work surfaces are located within the concentrated work space control area specified based on the number of desks included in the concentrated work space control area and information from the sensor device. Any value may be used as long as it is calculated based on the number of people who are thought to be working in The number of dice sensors with the desired side facing upward) may also be used.

If a negative determination is made in step S2 and the control device 61 determines that the need for a concentrated work space is high, the control returns and steps from step S1 onwards are repeated. On the other hand, if an affirmative determination is made in step S2, the process proceeds to step S3, where the control device 61 selects (the number of dice sensors whose faces are facing upward for which the non-intensive control mode is desired)/(for non-intensive work) It is determined whether the number of desks having work surfaces included in the space control area is less than or equal to a second predetermined value. Here, the control device 61 specifies (number of dice sensors whose surfaces for which decentralized control mode is desired are facing upward)/(number of desks with 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. 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.

Note that the second occupancy amount is the number of desks whose work surfaces are included in the non-concentrated work space control area and the work surfaces located within the non-concentrated work space control area specified based on 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 It may also be the number of dice sensors whose faces are facing upward for which the decentralized control mode is desired.

If an affirmative determination is made in step S3, and the control device 61 determines that the need for a non-concentrated work space is low, the control device 61 determines that there is no need to change the scene, and the control returns. Step S1 and subsequent steps are repeated. On the other hand, if a negative determination is made in step S3, the process proceeds to step S4, where the control device 61 determines that the range of the decentralized work space control area is insufficient for the demand for the decentralized control mode, and Switch 1 to scene 2. As shown in FIG. 2, in scene 1, desk group 1 having eight work desks D07 to D14 is a concentrated space, while desk group 1 having six work desks D01 to D06 is a decentralized space. It has become. Conversely, in scene 2, desk group 1 with 8 work desks D07-D14 is a non-concentrated space, while desk group 1 with 6 work desks D01-D06 is a concentrated space. It has become. Therefore, by switching scene 1 to scene 2, the space control area for non-concentrated work can be expanded and at the same time the space control area for concentrated work can be reduced, making it possible to respond flexibly and quickly to people's needs.

In step S5 after step S4, the control device 61 executes the following operations: (the number of dice sensors whose surfaces for which the centralized control mode is desired are directed upward)/(the desk having the work surface included in the concentrated work space control area) ) is above 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 concentration space, returns to step S4, maintains reproduction of 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, where the control device 61 selects (the number of dice sensors whose faces are facing upward for which the non-intensive control mode is desired)/(the non-intensive work It is determined whether the number of desks having work surfaces included in the space control area) is above the second predetermined value. If an affirmative determination is made in step S6, it is determined that switching to scene 1 will cause a greater disadvantage to those using the non-concentration space, and the process returns to step S4 to maintain 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 returns and steps S1 and subsequent steps are repeated.

(Configuration and effects 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, its effects, and the preferable configuration and its effects will be explained.

<Essential configuration and effects derived from the configuration>
The environment control system 10 includes a plurality of task lights 5 for illuminating the work surfaces (upper surfaces) of the work desks D01 to D14 in an ABW office (room) 20 in which the plurality of work 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 , location information of one or more people existing in the ABW office 20 , and information on the location of one or more people existing in the ABW office 20 , Dice sensor ( (sensor device) S1 to S14, and a control device 61. The control device 61 also controls a concentrated work space control area where the illuminance of the task light 5 is higher than the illuminance of the base light 3 and a non-concentrated work space control area where the illuminance of the task light 5 is lower than the illuminance of the base light 3. Zoning control is performed to control the dimming and color adjustment of the plurality of task lights 5 and the plurality of front base lights 3 so that this occurs. Further, in the environmental control system 10, when the control device 61 determines that the amount of the concentrated work space control area is small (the width of the concentrated work space control area is narrow) based on the information from the dice sensors S1 to S14, Controlling the light and color of the plurality of task lights 5 and the plurality of base lights 3 so that the amount of the concentrated work space control area is large (the width of the concentrated work space control area is wide), and the control device 61 determines that the amount of the concentrated work space control area is large (the size of the concentrated work space control area is wide) based on the information from the dice sensors S1 to S14, the amount of the concentrated work space control area is small. The control device 61 performs dimming and color toning control of the plurality of task lights 5 and the plurality of base lights 3 so that the width of the concentrated work space control area is narrow. 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 size of the decentralized work space control area is narrow). The control device 61 performs dimming and color adjustment control of the plurality of task lights 5 and the plurality of base lights 3 so that the control area is wide (wide), and the control device 61 controls the non-color adjustment based on the information from the dice sensors S1 to S14. If it is determined that the amount of space control area for concentrated work is large (the size of the space control area for non-concentrated work is large), the amount of space control area for non-concentrated work is determined to be small (the size of the space control area for non-concentrated work is large). At least one of the dimming and color toning control of the plurality of task lights 5 and the plurality of base lights 3 is performed so as to make the light narrower. Note that here, the term "quantity" can be defined as a physical quantity whose magnitude relationship can be defined, and this physical quantity can also be defined to include dimensionless quantities such as the number of objects. Therefore, the "amount" includes, for example, "size (area)" and "number."

According to the present disclosure, at least one of the concentrated work space control area and the non-concentrated work space control area is controlled based on the need for use of at least one of the concentrated work space control area and the non-concentrated 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 that occur on an hourly, daily, monthly, etc. cycle and the needs for each space.

<Multiple configurations that are preferable to select and the effects derived from each configuration>
In the environmental control system 10, control may be performed to widen the space control area for concentrated work, and at the same time, control may be performed to narrow the size of the space control area for non-concentrated work. At the same time, control may be performed to narrow the width of the non-concentrated work space control area, and control to widen the non-concentrated work space control area. Note that "simultaneously" preferably means within 30 minutes, more preferably within 10 minutes, even more preferably within 1 minute, and most preferably within 10 seconds. This is because if it takes less than 30 minutes, the layout change can be accomplished much faster and with less labor than a layout change that typically involves transporting and reinstalling fixtures and furniture. Moreover, this configuration is not an essential configuration and does not need to be executed. For example, the amount of the concentrated work space control area can be increased (concentrated work space control area Control may be performed only to increase the size of the area), or control may be performed to reduce the amount of the concentrated work space control area (narrow the size of the concentrated work space control area). . Alternatively, using the method described in detail above, only the control to increase the amount of the non-concentrated work space control area (increase the size of the non-concentrated work space control area) may be performed. Only the control that reduces the amount of the concentrated work space control area (narrows the size of the non-concentrated work space control area) may be performed.In other words, for example, whether the amount of the concentrated work space control area is increased or Only the control to reduce the amount of the non-concentrated work space control area is performed, and the control to change the amount of the non-concentrated work space control area may not be performed.Conversely, the control to increase or decrease the amount of the non-concentrated work space control area may be performed. It is not necessary to perform control to change the amount of the concentrated work space control area.

According to this configuration, when the size of the room is narrow, it is possible to effectively distribute the space control area for concentrated work and the space control area for non-concentrated work.

In addition, the control device 61 is configured to locate the work surfaces within the concentrated work space control area specified based on the number of work desks D01 to D14 included in the concentrated work space control area and information from the dice sensors S1 to S14. By comparing the first person occupancy amount, which is calculated based on the number of people who are considered to be using the work surface, with the first person occupancy threshold, the amount of the concentrated work space control area (the amount of Based on the information from the dice sensors S1 to S14, the number of work desks D01 to D14 whose work surfaces are included in the non-concentrated work space control area) is appropriate. 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 non-concentrated work space control area identified by the second person occupancy threshold; Then, the calculation is performed based on the calculation result information of the calculation unit 61c that performs at least one of determining whether the amount of the non-concentrated work space control area (the size of the non-concentrated work space control area) is appropriate. Light/toning control may also be performed.

According to this configuration, at least one of the needs for the concentrated work space control area and the needs for the non-concentrated work space control area can be objectively determined.

[Example 2]
In the first embodiment, a case has been described in which the dice sensors S1 to S14 are used to switch scenes with good responsiveness to people's needs, but the scenes may be switched only during a predetermined period. For example, in an office, etc., the lighting may be dimmed during the lunch break, but for scenes in the morning and after the lunch break until 4 p.m., the lighting is switched on when the task light 5 and base light 3 are turned on after the lunch break. It may be something that can be done. In this case, for example, each person who uses the ABW office 20 in the afternoon directly performs dimming/toning control using the desired information for the afternoon mode in the morning using some method explained in the sensor device section above. Send the signal to a control device or other information device, such as an operating terminal such as a tablet or smartphone, or a workstation or server on the cloud, and receive the signal directly from the sensor device, or receive the signal from the information device. The control device that receives the information may select the optimal scene based on the information. It should be noted that, as a precaution, although the first embodiment shows a mode in which the control device executes calculations and determinations of office space needs, this is not essential in the configuration intended by the present application. In other words, although not particularly shown in the drawings, it is obvious that the part that executes this calculation and determination may be located in, for example, a cloud server with a CPU, another personal computer, or a tablet, and any form can be selected.

In addition, in Example 1, zoning was performed only by controlling the dimming and toning of the task light 5 and the base light 3, but zoning was performed by controlling the dimming and toning of the task light 5 and the base light 3. It may also be executed by outputting sound.

In the second embodiment, a case will be described in which the scene is switched only during a predetermined period and zoning is performed using sound effects as well.

FIG. 6 is a 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 differs 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. Another difference is that instead of using dice sensors S1 to S14 as sensor devices, an information reading device 88 that reads a desired mode registered in advance in a mobile phone (smartphone) is used. The information reading device 88 is installed around the entrance of the ABW office 120, for example.

Further, as shown in FIG. 7, in the second embodiment, the control device 161 of the environmental control system 110 includes a control section 161a, a light adjustment color signal transmission section 161b, a calculation section 161c, and a sound signal transmission section 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 environmental control system 110 is connected to an information device (for example, an operating terminal, a workstation or server on the cloud) external to the control device 161 that directly controls dimming and color adjustment. 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.

To explain in more detail the acoustic effects of the plurality of speakers 109, in the environmental control system 110, four first to fourth speakers 109a to 109d are attached to the duct rail 104, and each speaker 109a to I connected the 109d wirelessly in stereo. Further, the first speaker 109a and the second speaker 109b constitute the speaker group 1, and the third speaker 109c and the fourth speaker 109d constitute the speaker group 2. The first and second speakers 109a and 109b belonging to speaker group 1 output the same first audio content, and the third and fourth speakers 109c and 109d belonging to speaker group 2 output the same second audio content. is now output. The first and second speakers 109a and 109b belonging to speaker group 1 output sound to people present in the area of desk group 1, and the third and fourth speakers 109c and 109d belonging to speaker group 2 output sound to people who are present in the area of desk group 1. A sound is output to people existing in the area of group 2. Note that the number of speakers belonging to speaker group 1 may be any number, and the number of speakers belonging to speaker group 2 may also be any number. Further, as the speaker 109, a directional speaker, for example, a parametric speaker, etc. may be employed. Because parametric speakers use ultrasonic waves, they can produce a sound that is highly directional.

With this configuration, for example, sound content in which the sound of a babbling stream was recorded was played back from the speaker group 1 located at the top of the desk group 1 via a smartphone. At the same time, sound content recorded with jazz and bossa nova music was played from speaker group 2 located at the top of desk group 2 via a different smartphone than the one mentioned above. Here, when I was seated at a desk belonging to desk group 1, I could hear the sound of a babbling stream, and I could only faintly hear jazz and bossa nova music. On the other hand, when I was seated at a desk belonging to desk group 2, I could hear jazz/bossa nova music and only the faint sound of a babbling stream. From the above, it has been confirmed that, for example, with such a configuration, it is possible to selectively provide different contents to different desk groups.

Furthermore, in the second embodiment, the scene settings shown in FIG. The scene was played. Information on the sound output by each lighting device in each scene was stored in advance in the storage unit 161e. For example, in addition to the sound output from speaker groups 1 and 2, if the above-mentioned scene 1 is played as a lighting control, desk group 1 will have the efficiency of concentrated work by lighting explained in scene 1 in Example 1. The effect that is easy to increase and the effect that is easy to increase the efficiency of concentrated work due to the sound of a babbling 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 concentrated work can be improved to a greater degree.

The sound of a babbling stream has characteristics similar to so-called white noise or brown noise, which has intensity in all frequency ranges. When this characteristic is expressed graphically as a Fourier transform spectrum of frequency versus intensity, it can be expressed as a graph of a Fourier transform spectrum that does not have intensity in the entire frequency domain, for example, a Fourier transform spectrum of frequency versus intensity of a specific scale note on the piano. In comparison with the graph of , it can be mentioned that the frequency characteristics of the sound in the graph are broad. More precisely, in zoning control, the spectral width in fast Fourier transform of the sound that is output at the maximum volume in the concentrated work space control area is the same as the spectral width in the fast Fourier transform of the sound that is output at the maximum volume in the non-concentrated work space control area. may be wider than the spectral width in the fast Fourier transform of the sound being played. Here, the spectral width refers to the spread width of the wavelength or frequency of a spectral line, and the intensity decreases to a certain predetermined width (for example, 1/2, 1/10, etc.) compared 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 spectral half-width (the width of the wavelength where the relative radiation intensity is 50% of the peak value in the spectral distribution of optical output). Sounds with this characteristic are noises that can reduce the efficiency of focused work that come from locations other than desk group 1 with various frequencies, compared to sounds that tend to have no intensity in the frequency domain, e.g. It has a remarkable effect of easily canceling noises, speaking voices, etc. Therefore, a worker working in desk group 1 will have difficulty hearing external noise. Therefore, the zone of desk group 1 can be made into an area where it is easier for workers to concentrate on their work and become absorbed in their work.

As the sound content that can improve the efficiency of concentrated work, it is preferable to use something similar in characteristics to the above-mentioned white noise or brown noise, but the present invention is not limited to this. For example, it may be music that mainly consists of natural environmental sounds such as the chirping of birds, the rustling of leaves in the forest, or the sound of ocean waves, or it may be music that is mainly composed of electronic sounds that are synthesized in waveforms by a music synthesizer or the like. Also good. The sound content may be a recording of natural sounds as is, a composition composed by a human, or a composition composed by a computer algorithm, AI, or artificial intelligence. The sound content may be a mixture of the various types of sounds mentioned above.

On the other hand, in the area where desk group 2 exists, scene 1 will be played in addition to the output of sound content recorded with jazz and bossa nova music, so as explained in Example 1, the color temperature will be adjusted. The effect of promoting a feeling of relaxation and smooth communication between multiple people based on low illumination light irradiation is superimposed with the effect of promoting a feeling of relaxation and smooth communication between multiple people due to jazz and bossa nova music. . Therefore, due to the synergistic effect of the superposition, the zone of the desk group 2 can be made into an area where workers can relax in each level and smooth communication among multiple people can be facilitated in each level.

Compared to the aforementioned white noise and brown noise, jazz bossa nova music has a characteristic that the frequency characteristics of the sound in the graph of the Fourier transform spectrum of frequency versus intensity are not broad. This is because instruments such as the piano, saxophone, and bass that primarily play jazz and bossa nova play a specific single scale, namely do re mi fa so la si do and its chromatic scales. This is due to the fact that it is used in a state where it is strictly tuned to output. Therefore, the above-mentioned noise canceling function against external noise tends to be poor, but in the first place there is little need for a noise canceling function in a co-creation space where the intention is to relax or communicate with multiple people. , even if the noise canceling function is reduced, no major harm will occur.

Furthermore, jazz, bossa nova, and the like are sound contents that are often provided 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, workers can feel a sense of relaxation and peace, and smooth communication can be realized.

Note that it is preferable to adopt sound content that is close to the characteristics called jazz or bossa nova as the sound content that can promote a feeling of relaxation and smooth communication among multiple people, but this is not particularly limited. For example, classical music, healing music, natural environmental sounds, etc. may be used as sound content that can promote relaxation and smooth communication among multiple people. Such sound content may be a recording of natural sounds as is, a composition composed by a human, or a composition composed by a computer algorithm, AI, or artificial intelligence. The sound content may be a mixture of the various types of sounds mentioned above.

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 purposes of the lighting and sound contents that can be predominantly provided to each desk group are the same. By doing so, the effects of the main idea intended by each desk group can be superimposed to create a synergistic effect, and the effects of the main idea intended by each desk group can be made remarkable.

Note that when lighting control and sound control are linked, their operations do not need to be strictly synchronized; for example, the start time or end time of lighting scene switching and the start time or end time of sound content switching are different. Even if there is some deviation, the above-mentioned effects will not be lost. In addition, if such a discrepancy occurs, the time difference between the start time or end time of the lighting scene change and the start time or end time of the sound content change may be any amount of time, but within 30 minutes. The time is preferably within 10 minutes, more preferably within 1 minute, and most preferably within 10 seconds. If the time difference is within 30 minutes, the layout change can be accomplished much faster and with less effort than a layout change that typically involves transporting and reinstalling fixtures and furniture.

<Evaluation results of spatial illumination and volume in scene 1>
Next, the results of a test of the illuminance and sound volume of the space in scene 1 will be explained. FIG. 9 shows information on the irradiation light emitted by each of the lighting devices 3 and 5 while outputting sound and reproducing scene 1 in Example 2, and the sound output from each speaker 109a to 109d. It is a schematic diagram explaining the information of. FIG. 10 also shows a light meter (CL-200: Konica Minolta) and a sound level meter placed across work desks D12 to D03 in the ABW office 120 of Example 2 while scene 1 is being played back. 2 is a graph showing the results of one test example when the illuminance and sound volume of a space were measured using (SD-2200: FUSO). Note that 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 sound volume of the passage provided between desk group 1 and desk group 2 are the lowest. Then, different illumination light is irradiated and different sound contents are reproduced on both sides of the passage. Furthermore, in desk group 1, it is possible to realize illumination light in which the illuminance locally increases rapidly on the desk surface. Furthermore, in desk group 1, sound content that promotes people's concentration is reproduced at high volume, and in desk group 2, sound content that gives people a feeling of relaxation and peace is output in desk group 1. The output is at about half the volume. Therefore, in this test example, the peripheral area of desk group 1 and the peripheral area of desk group 2 can be clearly separated (divided), and excellent zoning can be achieved. In addition, the lighting and sound content reproduced in the area around desk group 1 and the area around desk group 2 make the area around desk group 1 an excellent concentration space where people can easily concentrate on their work. On the other hand, the area around desk group 2 can be made into an excellent co-creation space where people can feel particularly relaxed and where multiple people can communicate.

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

Next, the timing of changing the scene in the second embodiment will be explained. In the second embodiment, each person who uses the ABW office 120 on a specific day and time (for example, Thursday afternoon) can set the desired mode on that specific day and time, that is, setting a space for concentrated work, setting for a space for non-concentrated work, etc. Set the space or one of the three options of not setting any mode in advance using an application on your operating terminal (for example, a tablet or a mobile phone such as a smartphone). Set it to . By bringing the operation terminal close to the information reading device 88 before a specific date and time, the information reading device 88 reads information that identifies the person, the selected mode, and the desired mode. The date and time information is read and sent to the control device 161 in a linked state.

Also, based on the information, the control device 161 determines that (for example, if the specific date and time is Thursday afternoon, immediately before the specific date and time is Thursday morning), ( (number of people desiring centralized control mode) / (number of desks with work surfaces included in the centralized work space control area) and (number of people desiring decentralized control mode) / (non-centralized control mode) The number of desks with work surfaces included in the concentrated work space control area is calculated.

Then, it is determined whether (number of people requesting the centralized control mode)/(number of desks with work surfaces included in the concentrated work space control area) is equal to or greater than a third predetermined value, and ( It is determined whether or not (number of people requesting the decentralized control mode)/(number of desks with work surfaces included in the decentralized work space control area) is equal to or greater than a fourth predetermined value. There is.

Then, (number of people who desire centralized control mode)/(number of desks with work surfaces included in the concentrated work space control area) is greater than or equal to a third predetermined value, and (who desires decentralized control mode) If the ratio (number of people working on the desk)/(number of desks with work surfaces included in the non-concentrated work space control area) is less than the fourth predetermined value, Scene 1 will be reproduced at a specific date and time. It has become.

Further, (number of people who desire the centralized control mode)/(number of desks with work surfaces included in the concentrated work space control area) is less than the third predetermined value, and (the number of people who desire the decentralized control mode) is less than the third predetermined value. If the ratio (number of people working on the desk)/(number of desks with work surfaces included in the non-concentrated work space control area) is equal to or greater than the fourth predetermined value, Scene 2 will be reproduced at a specific date and time. It has become.

Further, (number of people who desire the centralized control mode)/(number of desks with work surfaces included in the concentrated work space control area) is less than the third predetermined value, and (the number of people who desire the decentralized control mode) is less than the third predetermined value. If the ratio (number of people working on the desk)/(number of desks with work surfaces included in the non-concentrated work space control area) is less than the fourth predetermined value, scene 1 is reproduced (or scene 2 may be reproduced). It looks like this.

In addition, (number of people who desire the centralized control mode)/(number of desks with work surfaces included in the concentrated work space control area) is equal to or higher than a third predetermined value, and (the number of people who desire the decentralized control mode) When the number of people who are using the centralized control mode)/(the number of desks with work surfaces included in the decentralized work space control area) 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 the number of people who desire the decentralized control mode is greater than the number of people who desire the decentralized control mode, and conversely, the number of people who desire the decentralized control mode is greater than the number of people who desire the decentralized control mode. If the number is less than , scene 2 is reproduced.

In the second embodiment, by controlling scene reproduction in this way, active zoning can be realized that can appropriately respond to the fluid work performance of workers and organizations and the needs of each space at a specific date and time in the future.

Note that (number of people requesting the centralized control mode)/(number of desks with work surfaces included in the concentrated work space control area) is an example of the first demand quantity, and the third predetermined value is , is an example of the first demand threshold. Further, (number of people who desire the decentralized control mode)/(number of desks with work surfaces included in the decentralized work space control area) is an example of the second demand quantity, and the fourth predetermined demand quantity is an example of the second demand quantity. The value is an example of the second demand threshold.

In addition, the first demand is based on the number of desks whose work surfaces exist in the concentrated work space control area and 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, (number of desks with work surfaces included in the centralized work space control area)/(number of people desiring the centralized control mode). ) etc. may be used. In addition, the second demand quantity also calculates the number of desks whose work surfaces are located in the non-concentrated work space control area and the work surfaces located in the non-concentrated 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 the space, for example, (number of desks with work surfaces included in the decentralized work space control area)/(desired decentralized control mode). It may also be the number of people doing the same thing.

(Preferred configuration adopted in Example 2 and its effects)
As described above, in the environment control system 110 of the second embodiment, the control device 161 identifies the work surface based on the number of desks existing in the concentrated work space control area and the information from the information reading device (sensor device) 88. The amount of the concentrated work space control area ( the size of the concentrated work space control area) is appropriate, the number of desks whose work surfaces exist in the decentralized work space control area, and the information from the information reading device 88. By comparing the second demand amount calculated based on the number of people who wish to use the work surface located in the decentralized work space control area with the second demand threshold, the decentralized work space control area is The light adjustment/color adjustment control is executed based on the calculation result information of the calculation unit 161c that performs at least one of determining whether the amount (the size of the non-concentrated work space control area) is appropriate or not.

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

Furthermore, the environmental control system 110 may further include a plurality of speakers 109 that output sound into the ABW office (room) 120. Furthermore, in the zoning control, the plurality of speakers 109 may output sound to the concentrated work space control area and the non-concentrated work space control area. In addition, the spectral width of the fast Fourier transform of the sound output at the maximum volume within the space control area for concentrated work is the same as the fast Fourier transform of the sound output at the maximum volume within the space control area for non-concentration work. The spectral width may be wider than the spectral width of .

According to this configuration, it is possible to superimpose the effect of lighting to easily increase the efficiency of concentrated work and the effect of sound to easily increase the efficiency of concentrated work, and the synergistic effect of the superposition allows the space control area for concentrated work to be It is possible to change the efficiency of concentrated work to an area where it is easy to increase the efficiency. Furthermore, in the non-concentrated work space control area, the effect of lighting that tends to enhance relaxation and communication can be superimposed with the effect of sound that tends to enhance relaxation and communication. Therefore, due to the synergistic effect of their superposition, the non-concentration work space control area can be changed into an area where it is easier to feel a sense of relaxation and communication is much easier.

The device may further include one or more speakers that output sound into the room, and control at least one of the volume of the speaker and the content output by the speaker based on the calculation result information of the calculation unit. Here, the one or more speakers may be configured to be able to output sound only to one of the concentrated work space control area and the non-concentrated work space control area, and the environmental control system may include a plurality of speakers. , a configuration may be adopted in which a plurality of speakers can output sound to both the concentrated work space control area and the non-concentrated work space control area. As is clear from the above description, if the configuration of this modification is adopted, the differences between different regions can be highlighted by the sound output from the speaker.

(If you do not set the scene in advance)
Note that, unlike the cases described in the first and second embodiments, the scene does not need to be registered in advance in the storage unit of the control device. Then, the control device controls the dimming and toning of the one or more task lights and the one or more base lights individually, or controls the dimming and toning of each group based on the information from the sensor device. By doing so, the space control area for concentrated work and the space control area for non-concentrated work may be generated more flexibly and with a higher degree of freedom.

(Regarding the number of space control areas for concentrated work and space control areas for non-concentrated work)
Furthermore, in the first and second embodiments, a case has been described in which there is one space control area for concentrated work and one space control area for non-concentrated work. However, the concentrated work space control area may be composed of two or more parts arranged discretely from each other, and the non-concentrated work space control region may also be composed of two or more parts arranged discretely from each other. may be done. In addition, if both the concentrated work space control area and the non-concentrated work space control area are composed of two or more discretely arranged parts, the concentrated work space control area and the discrete The number of parts arranged in the area and the number of parts arranged discretely while constituting the non-concentrated work space control area may be the same number, or may be different numbers from each other. Here, in the zoning of the present disclosure, it is preferable to change the entirety of each part (island) into a concentrated work space control area or a decentralized work space control area at once. In addition, in relation to this description, the technology of the present disclosure provides information on a sensor device, that is, location information of one or more people in a room, presence information of one or more people in a room, and information on the presence of one or more people in a room. Zoning is performed based on at least one piece of personal information of one or more existing people. Therefore, it goes without saying that the technology of the present disclosure does not include a technology for changing the work surface corresponding to each seat into a concentrated work space control area or a non-concentrated work space control area at the individual's will.
