[ example 1]
(purpose and outline of control to be achieved in the environmental control system of the present disclosure)
In embodiment 1, first, the purpose and outline of control to be achieved in the control in the environment control system of the present disclosure will be roughly described. Next, a detailed description of each configuration of the environment control system, an example of specific control that can achieve the purpose, and the like will be described.
Fig. 1 is a diagram showing an example of the layout of the arrangement of the plurality of desks D01 to D14 that can be performed in the ABW office 20 that is an example of a room in which the environment control system 10 according to the embodiment 1 of the present disclosure is installed, and is a layout diagram in which the arrangement of the plurality of desks D01 to D14 and the arrangement of the base lamp 3, the power-on lamp rail 4, and the work lamp 5 that are installed on the ceiling of the ABW office 20 are described in a form superimposed on the arrangement of the desks D01 to D14 when viewed from above.
In one embodiment of the ABW office 20 shown in fig. 1, a total of 14 office tables D01 to D14, which are general office tables, are classified into a desk group 1 and a desk group 2, 28 LED dimming and color-adjusting base lamps (for example, NNLK41515+ NNL4600EXDK 9: panasonic) as ambient lighting for illuminating the ABW office 20 are provided at equal intervals above the desk groups, and 3 rows of lamp rails 4 for power supply are provided in the vicinity thereof. Specifically, 14 desks D01 to D14 in total are arranged in 4 rows, and 3 power supply lamp rails 4 are arranged in the vicinity of 3 desks D01 to D14 in the 4-row desks D01 to D14 so as to extend in a direction substantially parallel to the extending direction of the rows.
A total of 14 work lamps 5 are provided on each lamp rail 4. As the work light 5, an LED dimming type spotlight (for example, NTS 05121W: loose) 5 is used. Further, a wavelength conversion filter is added to the opening of each operating lamp 5, and the color temperature of the output light from the operating lamp 5 is adjusted to 6000K. Then, a total of 14 desk lamps D01 to D14 are in one-to-one correspondence with a total of 14 desk lamps 5, and the installation position and installation direction of each of the desk lamps 5 are adjusted so that each of the desk lamps 5 illuminates the central portion of the corresponding desk lamps D01 to D14.
The 28 base lamps 3 and 14 work lamps 5 are connected in sequence via dimming signal lines to a multi-manager (japanese: マルチマネージャー, for example, NQ 51101: panasonic), an LS/PD signal conversion interface (NK 51111: panasonic), a PD/dimming signal conversion interface (NK 51012: panasonic) and a pip + independent unit controller a type (japanese: セパレートセルコン a タイプ, for example, NQ 23171Z: panasonic) as examples of the control device. Further, 7 work lamps 5 were paired for each of the prepared 2 pip + independent unit controller a types.
Dice sensors S1 to S14 are disposed on the work surfaces of the desks D01 to D14. The die sensors S1 to S14 are die IoT devices having a substantially cubic shape like a die, and are dice-type devices "electronic dice" having an acceleration sensor and a wireless communication function. The die sensors S1 to S14 are disposed on the work surface so that a person (worker) can select a desired mode. More specifically, the 6 planes of the die sensors S1 to S14 include a plane indicating the spatial control region for voting (desired) concentrated work, a plane indicating the spatial control region for voting (desired) non-concentrated work, and a plane indicating that none of the 2 spaces is selected and indicating neutral.
The die sensors S1 to S14 each detect how much the die is rotated in which direction by a built-in acceleration sensor, and determine which face is facing upward. Then, the die sensors S1 to S14 transmit the results to a terminal or the like including an arithmetic unit, for example, an operation terminal including the aforementioned multi-manager, tablet, smart phone, personal computer, or the like, via a wireless communication network built in the ABW office 20. When the user leaves the seat after the end of the work in the ABW office 20, the user should take an action to face the dice sensors S1 to S14 to the neutral position and leave the seat. Accordingly, the multi-manager or the operation terminal can determine how many persons are working using the desks D01 to D14, how many of the working persons desire the centralized working space control area, and how many of the working persons desire the non-centralized working space control area. A plurality of die sensors (14 die sensors in the case of embodiment 1) S1 to S14 constitute a sensor device. As a method of wireless communication of the die sensors S1 to S14, a method conforming to the ieee802.15.4 standard can be suitably adopted.
Next, using the multi-manager operation application, the position information of each base lamp 3 is stored through the mapping work of 28 base lamps 3, and as shown in fig. 1, 12 base lamps 3 and 8 work lamps 5 are set as the lighting apparatuses belonging to the lighting group 1, 4 base lamps 3 are set as the lighting apparatuses belonging to the lighting group 2, and 12 base lamps 3 and 6 work lamps 5 are set as the lighting apparatuses belonging to the lighting group 3. As shown in fig. 2, 4 scenes are set for each of the lighting groups 1 to 3, and values of the color temperature and the dimming ratio of each group in each scene are set.
Here, the setting of each scene can be easily performed using an operation terminal, for example, a smartphone, a tablet computer, a remote controller, or the like, in which an application for setting an existing scene is installed. Then, the scenes are actually reproduced. Specifically, when scene 1 is reproduced using operation unit 64 (see fig. 3) after the blinds of the windows of ABW office 20 are completely closed, desk group 1 and desk group 2 are divided into separate parts in appearance. Next, when other scenes such as scene 3 and scene 4 are sequentially reproduced using the operation unit 64 (see fig. 3), each scene is switched in the order of several seconds.
The group 1 of desks 1 in scene 1 has an uneven illuminance distribution in which only the central portions of the desks D07-D014 have high illuminance and the illuminance decreases as the distance from the central portions increases. Further, the illumination intensity of the floor, wall, and the like around the desk is also low and the brightness is low. In the desk group 1 in scene 1, the illuminance of the work lights is higher than that of the base lights on the work surfaces of the desks D07 to D014. In the present disclosure, the work surface of the desk where the illuminance of the work light is greater than that of the base light is defined as the centralized work space control area. When a person who performs a job using the work surfaces of the desks D07 to D014 wants to set the work surfaces of the desks D07 to D014 used by the person to be the centralized work space control area, the space voted (desired) by the dice sensors S1 to S14 is the centralized work space.
On the other hand, in the desk group 2 of the scene 1, the illuminance distribution of the desks D01 to D06 is more uniform than that of the desk group 1, and is a space with high illuminance and a high brightness feeling of the floor, wall, and the like around the desk. In the desk group 2 in scene 1, the illuminance of the work lights is lower than that of the base lights on the work surfaces of the desks D07 to D014. In the present disclosure, the work surface of the desk where the illuminance of the work light is lower than that of the base light is defined as a non-centralized work space control area. When a person who performs a job using the work surfaces of desks D07 to D014 wants to set the work surfaces of desks D07 to D014 used by the person to be the non-centralized work space control region, the space voted (desired) by using the dice sensors S1 to S14 is a non-centralized work space.
At this time, when the worker sits on the desk group 1, the central portions of the desks D07 to D014, which the worker should watch more, are illuminated with high illuminance, and therefore, the noise factor for recognition of the peripheral visual field is reduced, so that the worker is likely to be buried in the work, and the efficiency of the concentrated work is likely to be improved. In addition, in this technique, the visibility of the peripheral vision of the wall, floor, and the like is reduced by setting the dimming ratio of the base lamp 3 low, and therefore, the effects of being countersunk in the desks D07 to D014 and the work can be more easily improved. Further, by setting the dimming ratio of the base lamp 3 low, the worker who is working with the desk group 1 cannot see the expression of the face when other workers see from the outside or cannot see pleasure due to the shadow of the face, and therefore, it is difficult to make a call. That is, the probability of the worker who is performing work using the desk group 1 being called by another worker and causing a job interruption is likely to decrease, and as a result, the efficiency of the collective work is likely to be improved for the worker who is performing work using the desk group 1. As described above, when scene 1 is reproduced, the desk group 1 is a space that easily functions as a concentrated space. On the other hand, in the scene 1, the desk group 2 has a low color temperature, and is easy to improve a sense of relaxation and an amount of communication performed by a plurality of people, and therefore, is a space that is easy to function as a non-concentrated space (a relaxed space, a shared space).
The spatial illuminance distributions of the desk group 1 and the desk group 2 are greatly different. In particular, the desk group 1 is characterized by a lower illuminance on the floor, wall, or the like around the desk, which is a factor of the high feeling of separation of the two desk groups in terms of the appearance space. Further, since the color temperatures of the illuminations of the desk group 1 and the desk group 2 are greatly different, the sense of spatial division in appearance is high. As described above, the partitioning effect of cognitively partitioning a space is obtained without using daily utensils, furniture, or the like. Regarding the partitioning effect, the larger the difference between the illuminance distribution and the color temperature of each group is, the more easily the effect is enhanced.
Further, since the contents of the work that the operator is prompted to perform are different between the desk group 1 and the desk group 2, for example, the concentrated work is prompted to be performed in the desk group 1 and the relaxation and communication are prompted to be performed in the desk group 2 of the present embodiment, the effects are different not only in the appearance but also in the method of using the functionality of each space, and thus the effects also contribute to the partitioning effect.
In addition, in the case of performing the division by this method, switching of each scene is completed within several seconds, and as a result, the layout of the ABW office 20 can be changed within several seconds. For example, when the number of the centralized work space control areas is expected to be large using the die sensors S1 to S14 due to a situation such as a day in which the demand for the centralized space is high, for example, a day in which the office is busy, the arithmetic unit that receives the signals from the die sensors S1 to S14 determines that the demand for the centralized work space is high, and switches the scene from scene 1 to scene 3 by the multi-manager so that the centralized work space control area of the ABW office 20 is increased from 8 work surfaces to 14 work surfaces. Alternatively, when it is desired to increase the number of the centralized work space control areas using the die sensors S1 to S14, the operation terminal that receives the signals from the die sensors S1 to S14 determines that the demand for the centralized work space is high, and switches the scene from scene 1 to scene 3 by controlling the multi-manager so that the centralized work space control area of the ABW office 20 is increased from 8 work surfaces to 14 work surfaces. Thus, the requirement of the staff for the centralized space is met, and the work performance of the staff and the organization is easily improved as a result.
Alternatively, when it is desired to increase the number of non-centralized working spaces due to the conditions of the leisure day or the like using the die sensors S1 to S14, the arithmetic unit that receives the signals from the die sensors S1 to S14 determines that the demand for the non-centralized working space control area is high, switches the scene to scene 4 via the multi-manager so as to reduce the centralized working space control area of the ABW office 20, and increases the non-centralized working space control area from 8 working surfaces to 14 working surfaces. Alternatively, when it is desired to increase the number of non-centralized-work spaces using the die sensors S1 to S14, the operation terminal that receives the signals from the die sensors S1 to S14 determines that the demand for the non-centralized-work space control area is high, and switches the scene to scene 4 via the multi-manager so as to reduce the centralized-work space control area in the ABW office 20, while increasing the non-centralized-work space control area from 8 work surfaces to 14 work surfaces. In this way, the space control region for intensive work is reduced, while the space control region for non-intensive work is set to 14 work planes, whereby the shared space can be increased, and the pressure of the tissue can be easily reduced, and the traffic flow rate can be increased. In addition, at this time, it is not necessary to immediately perform switching of scenes by control by the multi-manager or control by the multi-manager via the operation terminal. For example, if the scene switching is performed after the reception of a desired signal suggesting such a worker and after noon break in the ABW office or the business start time of the next day, it is possible to prevent unnatural feeling and uncomfortable feeling due to a sudden environmental change from being given to the worker who is already performing the work, which is preferable. In the configuration mentioned above, the receiving unit and the arithmetic unit that receive the signals from the die sensors S1 to S14 may not be provided inside the multi-manager case. In this case, the control device may include a receiving unit that receives signals from the die sensors S1 to S14, a computing unit, and a multi-manager.
The control device may learn (analyze) the tendency of the demand for the centralized working space control region and the tendency of the demand for the non-centralized working space control region at each time of one week based on the information from the die sensors S1 to S14. The control device may determine the demand for the concentrated work space control area and the non-concentrated work space control area in the afternoon (or morning) of a predetermined day of the week (for example, thursday), and select a scene to be realized based on the determined demand.
According to this method, as described above, if a method using daily appliances/furniture is used, flexible division in which the layout is changed at intervals of an hour, a day, a month, or the like, which is difficult to realize, can be performed. In a conventional office scene, areas such as desks and aisles are generally illuminated with high uniformity of color temperature and illuminance distribution. In contrast, in the present application, since the illumination method and the control method that make the color temperature and the illuminance distribution uneven are used, particularly in the ABW office scene, the division of the centralized working space control area and the non-centralized working space control area can be flexibly and quickly performed to meet the needs of the centralized working space control area and the non-centralized working space control area, and a significant effect that cannot be expected from the conventional knowledge of illumination can be realized.
(details of the respective configurations of the environment control system 10)
The purpose and outline of the control to be achieved by the control of the environment control system 10 of the present disclosure are described above. Next, each configuration of the environment control system 10 will be described in detail. Fig. 3 is a block diagram showing an example of a main configuration that can form the environment control system 10. As shown in fig. 3, the environment control system 10 includes an operation unit 64, in addition to the die sensors S1 to S14, the base lamp 3, the work lamp 5, and the control device 61 including a multi-manager, and the control device 61 includes a control unit 61a, a light/color adjustment signal transmission unit 61b, a calculation unit 61c, and a storage unit 61 d. The control device 61 is preferably constituted by a computer, for example, a microcomputer, and the control section 61a, that is, the processor, includes, for example, a CPU (Central Processing Unit). The storage unit 61d is configured by a nonvolatile Memory such as a ROM (Read Only Memory) or a volatile Memory such as a RAM (Random Access Memory). The CPU reads out and executes a program or the like stored in advance in the storage section 61 d. The nonvolatile memory stores a control program, a predetermined threshold value, and the like in advance. The volatile memory temporarily stores the read program and processing data. The storage unit 61d stores position information and device identification information, which are set in advance, relating to each of the one or more operation lamps 5 and the plurality of base lamps 3. The storage unit 61d stores data for reproducing the light-adjustment and color-adjustment of the scenes 1 to 4. In example 1, 8 desks D07-D014 belong to desk group 1, and 6 desks D01-D06 belong to desk group 2, but the number of desks belonging to desk group 1 and desk group 2 is not limited to example 1. The number of the illumination groups is not limited to 3 as in embodiment 1, and any number of two or more illumination groups may be present. Next, the respective configurations of the position information, the device identification information, and the environment control system 10 will be described in detail.
(about information)
< location information >
The positional information may be information similar to the absolute value of coordinates such as the actual position in space, or may be information of a relative positional relationship with reference to a certain work light, a base light, or a post or the like already provided in space. The positional information stored in the storage unit 61d may be information that can be reproduced (defined) only partially, without being able to completely reproduce the positions and positional relationships of the work light and the base light that are actually installed. The position information may be recorded in the storage unit by user input, or may be recorded by an algorithm of an AI or a computer. The position information may be set and recorded by referring to or in association with drawing data stored in a separate storage unit or the like. Further, it is not necessary to give location information to all the devices included in the environment control system or to associate location information with all the devices, and it is also possible to make an appropriate selection according to the situation of the user.
< device identification information >
The device identification information is information that can be identified by the device, such as a spotlight or a base light, and is constituted by a manufacturing number, a MAC address, an IP address, a product number, and the like. The device identification information is used when setting/recording the above-described position information, group, scene, or when setting/recording the output parameters (the color tone ratio, the light tone ratio, and the like) of the devices individually so that different devices in the environment control system are not determined to be the same device unintentionally. The device to be given or associated can be appropriately selected according to the situation of the user without giving the device identification information to all the devices included in the environment control system or associating the device identification information with all the devices.
(details of the respective structures)
< working Lamp >
The device form of the work light is not particularly limited, and as the work light, besides the spotlight described above, a desk lamp, a downlight, and the like can be used, but as the work light, if the light distribution control is performed such that light is concentrated in a specific area like a spotlight, it is easy to control the illumination range of the desk, which is preferable. More specifically, the spotlight may have a structure in which the irradiation direction of the spotlight is adjusted by applying an external force by a person, or may have a structure in which the irradiation direction of the spotlight is automatically adjusted to any one of the lower directions by freely rotating two rotating shafts by a motor or the like using a remote controller. When the at least one spotlight can change the emission direction of the illumination light to any one direction at the set position, then the degree of freedom of the gap between the desks in the long-side direction in the concentration space can be improved, and also the degree of freedom of the gap between the desks in the width direction in the concentration space can be improved, so that the degree of freedom of the layout of the concentration space can be improved. In addition, when at least one of the spotlights is of a type that allows the irradiation direction of the spotlight to be freely adjusted by a remote controller, the irradiation direction of the spotlight can be safely adjusted from the ground without using a ladder or the like. Further, as described above, it is preferable to use a spotlight of a dimming and toning type as the work light.
The task lamp is an illumination for improving the efficiency of work by an operator, for example, work such as personal computer work, note-taking work, and reading work, and is an illumination for selectively illuminating a visual target area of a desk. The visual target area is an area that is generally likely to enter the visual field when a work is performed using the desk, and for example, when a personal computer (hereinafter, simply referred to as a personal computer) is placed on the back side of the center of the desk and operated, the center of the desk is the center of the visual target area. In this case, the change in the visual object due to the physiological factors or the incidental posture or visual line change is not considered, that is, the following phenomenon is not considered as a significant change in the visual object region in the desks D01 to D14: looking up at the ceiling for temporary thinking, stretching to lazy waist; moving the sight to the wall; sneezing and coughing can cause vision to shift to the floor; the line of sight is moved by being called by someone.
The illumination range of the work light is preferably defined as a part of the visual object area, and for example, it is preferable that 30% to 90% of the area of the desk is the illumination range. The illumination range of the work lamp is not particularly limited, and is preferably substantially circular or substantially polygonal. As a result, the luminance of the visual target region becomes brighter than the luminance of a region other than the visual target region, and the cognitive noise in the peripheral visual field is reduced. Therefore, the awareness of the worker is directed to the desk side, and the working efficiency is easily improved.
Here, the illumination range can be calculated as a range generally called a half-value width, where the maximum value of the amount of light per unit area reaching the desk is halved. The illumination range can be measured and calculated by using a known illuminometer. The color temperature of the operating lamp is not particularly limited, but 4000K to 6500K is preferable because cognitive concentration tends to be improved.
< basic Lamp >
The base lamp is an illumination for increasing the brightness of the room, and is an illumination for uniformly illuminating the room. In order to uniformly illuminate the room, the light distribution of the base lamp is preferably in a range larger than that of the spotlight. The color temperature of the base lamp is not particularly limited. The base lamp is preferably dimmable and dimmable. The device form of the base lamp is not particularly limited, and any device form such as a ceiling lamp, a line lamp, a head lamp, a spotlight, and a light bar can be used.
< sensor device >
The sensor device may be any device capable of detecting at least one of position information of one or more persons present in the room, on-duty information of one or more persons present in the room, and personal information of one or more persons present in the room. For example, in embodiment 1, a case where the sensor device is configured by a plurality of die sensors is described, but the sensor device may be a seating sensor (weight sensor) that is attached to each of the same number of chairs as the number of desks D01 to D14, or may be a human sensor (optical sensor) that can detect whether or not a human is seated on each chair.
Alternatively, the sensor device may be a device capable of specifying the distribution of people in a room, or may be an LPS (Local Positioning system) (registered trademark), a camera, a lidar, or the like capable of detecting position information of people. The LPS includes a beacon that is carried by a person (directly held by the person or attached to an article held by the person) and that transmits position information, a scanner, and a control device. A scanner mounted on the ceiling receives signals from the beacons and determines location information. The control device determines 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 the expression of a person based on a captured video. The LPS may be an LPS system including a position information analysis unit that analyzes the number of people and the usage rate of the space based on the position information. Alternatively, the sensor device may be a device for measuring indoor sound, or may be a microphone or the like. The microphone may be a microphone system including a sound analysis unit that analyzes the number and state of persons based on a recorded sound at any position inside and outside the microphone main body. By using such a device as a sensor device, it is easy to automatically determine a control method of the control device even if a worker does not particularly perform an operation action on some terminals, which is preferable.
Alternatively, the sensor device may be an ID information acquisition device such as a card reader for detecting ID information (identification information). In this case, the control device can determine, for example, which of the centralized work space and the non-centralized work space is frequently used as the personal information of each worker, which space is preferred, and the like, based on the information from the ID information acquisition device.
Alternatively, after the ID information is detected, a desired pattern may be stored in a cloud server or the like by wireless or wired communication so that the information can be learned. That is, the learning may be performed by detecting the ID information and the versatility of the other sensors, and the control device may automatically determine the space desired by the person who has detected the ID information based on the learning.
The ID information may include attribute information in the office, such as an identification number, an identification symbol, a name, a sex, an organization to which the person belongs, schedule information, information on a terminal used in a business, an action history, information on a vital sign, reservation information of a facility, and personnel information, which are related to the ID, and these pieces of information may contribute to a control method of the control device.
The personal information includes information for announcing (desiring) a request for a control method of each worker for the office space, such as a request for a centralized work space control area or a request for a non-centralized work space control area. As an example of performing control only by personal information, the following configuration may be adopted: a desired pattern of the person is set in advance in an application program of an operation terminal such as a smartphone, and the operation terminal is brought close to a detection device (in this case, the detection device is a sensor device) for detecting the pattern, so that the detection device reads the desired pattern and transmits the pattern to a control device. Alternatively, the sensor device may be an operation unit (configured by an operation interface or the like) for inputting a desired mode when entering a room. Further, it is also possible to select a space for collective work or a space for non-collective work when a person enters the room. The personal information intended in the present application also includes anonymous information that does not specify a person who is a source of a declaration (desire), which is obtained by, for example, an electronic die, an electronic voting system, or the like. In other words, it is not necessarily required to associate a declaration (expectation) with attribute information of a worker.
< control device >
The control device 61 is a device for controlling the work light and the base light. Here, the control includes on-off control and dimming/toning control. The device form of the control device 61 is not particularly limited, and as the device form of the control device 61, for example, the lighting control device and the control application program of the lighting control device described in embodiment 1 can be preferably used. The device control application may be installed in a terminal such as a tablet pc, a personal computer, or a smartphone, in addition to the multi-manager illustrated in fig. 3, and in this case, it is preferable for the user to easily set, manage, and operate the lighting control device.
In detail, in the example shown in fig. 3, the control device 61, which is configured by a plurality of managers, receives signals directly from the die sensors S1 to S14, for example. However, as shown in fig. 4, for example, the control device 71 including a plurality of managers may be configured to be controlled by receiving a signal from an operation terminal (e.g., a tablet pc or a smartphone) 79. In this case, the operation terminal 79 may receive signals from the die sensors S1 to S14 and may transmit control signals to the control device 71 based on the received signals. The operation terminal 79 may have the operation unit 73 and the operation unit 75. That is, the control device 71 of the environment control system 70 may be a terminal or a device different from the operation terminal such as the tablet pc 72, or may be configured by a plurality of managers or the like. Here, the control device 71 may be configured such that a housing thereof is embedded in a ceiling or a wall surface, or may be fixed to a floor or a storage rack. The control device 71 may be controlled by signal communication with an operation terminal such as the tablet pc 72 by a wired system, or by signal communication by a wireless system such as Wi-Fi or Bluetooth (registered trademark). In this case, although not particularly shown in fig. 4, the control device 71 may include a communication device having a port for connecting a signal line for communication and an access point of a wireless LAN. In this case, the tablet pc 72 or the like may not directly communicate with the work light 5 or the base light 3. At this time, information on the positions and control conditions of the appliances constituting the environment control system 70, such as a map, a scene, a group, and a control schedule set by the operation unit 75 of the tablet pc 72, may be transmitted to the control device 71 and recorded in the storage unit 76 of the control device 71. In this case, even when the power supply of the tablet pc 72 is turned off or the tablet pc 72 is stored in a place outside the communication range with the work light 5 and the base light 3, the intended environmental control can be performed. The control device 71 may not have a user interface for operation such as a liquid crystal display. In this case, the control device 71 is preferably easy to be downsized, and is improved in installation easiness and design feeling. Although not particularly shown in fig. 4, the operation terminal such as the tablet pc 72 may have a storage unit. Further, although the environment control system 70 shown in fig. 4 is a modification of the environment control system 10 shown in fig. 3, it is clear that there are many environment control systems of modifications that can be realized and are conceivable in addition to the environment control system 70 shown in fig. 4.
< calculating section >
The calculation unit includes the following calculation processes: based on the information obtained from the sensor device, a demand relating to the amount of office space, for example, the proportion of the amount of the centralized work space or the non-centralized work space in the present application, is determined. As shown in fig. 3, the arithmetic unit 61c is configured by, for example, a multi-manager or the like, and may be incorporated in the control device 61 that directly performs the light/color adjustment control, or may not be incorporated in the control device 61. Further, as shown in fig. 4, when not being incorporated in the control device 71 that directly performs the dimming/toning control, the control device may be configured by an information device different from the control device 71 that directly performs the dimming/toning control, for example, an operation terminal such as a smartphone, a tablet computer, or a personal computer, or a storage medium of a server, a workstation, or an external device on the cloud. The arithmetic unit executes arithmetic processing programmed in advance, but the program may be rewritten during use. The rewriting of the program may be performed manually by editing software or a personal computer, or may be performed automatically and without a person based on a learning result of past accumulated data such as AI. The calculation process included in the calculation unit is not particularly limited in the range of processing information obtained from the sensor device, but for example, desired information voted by a plurality of workers may be counted by four arithmetic operations, information on the number of persons obtained from an LPS system, a camera system, or the like may be counted by four arithmetic operations, or a demand relating to the amount of office space may be predicted by a statistical calculation method such as regression analysis based on the above statistical information and past accumulated data. The calculation result obtained by the processing in the arithmetic unit is fed back to a control device that is configured by a multi-manager or the like and directly performs dimming/toning control, for example, and contributes to at least a part of a control method of the control device. This is preferable because flexible handling can be performed according to the situation of the office that changes from moment to moment. The calculation result of the calculation unit does not necessarily need to be fed back to the control device that directly performs the light/color adjustment control, and for example, a graph of a change in the usage state of each space over time, information on the performance of the worker or organization, and the like may be output. This is preferable, particularly for the person in charge of the office and the person in charge of the general service, because it is easy to grasp the method of use of the office and the performance of the staff and the organization, which are difficult to be constantly known at ordinary times.
< light/color modulation Signal transmitting section >
The dimming/toning signal transmitting section 61b is a section that transmits a dimming/toning signal to the work light and the base light to cause the work light and the base light to perform at least one of dimming and toning, and the dimming/toning signal transmitting section 61b is included in the control device 61. The signal format is not particularly limited, and any known dimming signal, such as Wi-Fi or BlueTooth (registered trademark), can be used. In addition, in the above-described dimming/toning control, the dimming/toning control by the digital control method is described, and the control method of transmitting the digital signal (PDCL) from the lamp controller is described. In this control method, not only the power supply line but also the wiring of the signal line for digital control is required. In this digital control, since communication of detailed information is possible, control using a large amount of information is possible, and control based on a wireless signal is also included in this method.
However, when dimming and toning control is performed, a phase control method may be employed, and dimming control may also be performed by directly adjusting power supplied to the illumination apparatus. In this embodiment, the power supply current to the lighting device is directly controlled, and thus the lighting device is easily affected by voltage fluctuation, but since a dedicated signal line does not need to be separately drawn, workability is excellent. In addition, when dimming and toning control is performed, a signal line system may be employed, and a dimming signal (duty signal) may be transmitted from a lamp controller, and the luminance of a light emitting portion such as an LED may be controlled by a power supply unit on the device side. In this method, the power supply line and the wiring of the dimming signal line are required, but the method is less susceptible to the influence of the line voltage, and therefore smooth dimming control without flicker can be performed. In addition, on/off control of only the operating lamp and the base lamp is also included in the dimming control.
< storage section >
Any known device may be used as the device constituting the storage unit. The storage unit may not be incorporated in the control device unlike the configuration shown in fig. 3, and may be constituted by, for example, an information device different from the control device that directly performs the light and color adjustment control, such as a smartphone, a tablet computer, or a personal computer, or a server, a workstation, or an external storage medium on the cloud. The storage unit may be configured to be basic by a user, or may be configured to be rewritten by the device through the cloud and the AI.
< group information of a plurality of devices >
The group information of a plurality of lighting devices is managed, for example, by an application. The packetization may be performed by, for example, operating a tablet terminal to perform setting/saving. The plurality of devices that are packetized are simultaneously sent the same command, for example, are applied with the same dimming/toning control. Further, regarding dimming/toning control, i.e., group control, of a plurality of devices grouped together, signal delay is allowed, and variation in operation of the devices is also allowed. For example, the allowable variation in the operation of the device is within 30 minutes, more preferably within 10 minutes, still more preferably within 1 minute, and most preferably within 10 seconds, and the delay of the signal or the command converging within this range is included in the behavior of the plurality of devices subjected to the packetization. When the operation deviation of the equipment is within the above time, it is preferable that the layout change is performed quickly enough compared to a general layout change involving transportation or rearrangement of daily appliances or furniture, and the layout change is easily performed with less labor. The function of the application program for operating the control device may include setting of the group, but is not limited to being defined by the name "group". If the group is set in advance in the application program for operating the control device or in the storage unit included in the control device, it is easy for the user to manage and change the lighting and the control parameters thereof, which is preferable.
< control scenario information >
It is a very complicated task for a user to set various control parameters such as dimming ratio and color ratio for a plurality of lighting apparatuses and reproduce the control parameters. This is because, in a general ABW office, 10 or more or 30 or more lighting apparatuses are used, and if there are many lighting apparatuses, 100 or more lighting apparatuses are used. Therefore, a method of storing and managing control parameters of a plurality of lighting apparatuses in a storage unit is known, and this is referred to as a scene in the present application. In this way, it is easy for the user to manage the conditions of the control parameters for the plurality of lighting apparatuses, and to instantaneously reflect (hereinafter, referred to as reproduction) the conditions at a desired timing by the plurality of lighting apparatuses, which is preferable. The user can instantaneously switch the intended two or more setting conditions by storing a plurality of scenes in the storage unit in advance. The setting of each scene may be set in any manner according to the use requirement, and for example, unlike the example shown in fig. 2, the dimming rates of 10 base lamps may be set to 100% in the scene 1 and stored in the storage unit, and the dimming rates of the 10 base lamps described above may be set to 30% in the scene 2 and stored in the storage unit. Further, if scene 1 is reproduced, the state may be instantaneously changed to a state in which the dimming rates of 10 base lamps are set to 100%, and if scene 2 is reproduced from this state, the state may be instantaneously changed to a state in which the dimming rates of 10 base lamps are set to 30%. In this way, it is preferable to perform dimming control of many lighting apparatuses in a very short time and with less labor than the work of resetting the dimming ratio of 10 lighting apparatuses each time. Further, the setting of a scene may be included as a function of an application program for operating the control device, but is not limited to being defined by a name such as "scene". Further, the setting of each scene may be set as follows for the scenes of the groups 1 and 2. Here, the group 1 may be constituted by, for example, 10 base lamps, and the group 2 may be constituted by other 10 base lamps. Also, for example, in scenario 1, a group 1: dimming ratio 0%, group 2: the dimming ratio of 50% may be set to set group 1: dimming ratio 50%, group 2: the dimming ratio is 0%. If the scene is set in this manner, it is possible to instantaneously exchange a region in which workers can easily gather and a region in which workers can easily relax and can easily communicate with other workers, and when the sizes of the two regions are different, it is possible to instantaneously change the size of each region as needed. In addition, regarding dimming/toning control, i.e., group control, of a plurality of devices that have been made into a scene, a signal delay is allowed, and variations in the operation of the devices are also allowed. For example, the allowable variation in the operation of the device is within 30 minutes, more preferably within 10 minutes, still more preferably within 1 minute, and most preferably within 10 seconds, and the delay of the signal or the command converging within this range is included in the behavior of the plurality of devices that have been subjected to the scenization.
< space for concentration >
The concentration space may also be defined as follows. More specifically, when two or more tables having work surfaces on which the work lamps have higher illuminance than the base lamps are disposed in series and adjacent to each other, one table included in the two or more tables and facing the other table through the plane is determined when an arbitrary plane intersecting at least one of the two or more tables among planes including the vertical direction is considered and the plane intersects the other table other than the two or more tables on at least one side of the two or more tables. Then, a line segment area (an area that appears as a line segment when viewed from above in the vertical direction) on the one table side from the center of the end portion on the other table side of the one table where the plane intersects with the end portion on the one table side of the other table where the plane intersects with the plane may be defined as the concentration space.
In addition, when two or more tables having a working surface in which the illuminance of the working lamp is larger than that of the base lamp are arranged continuously and adjacently, when considering an arbitrary plane intersecting at least one of the two or more tables among planes including the vertical direction, in the case where the plane does not intersect with any other table other than the two or more tables on at least one side of the two or more tables, a line segment area (an area that appears as a line segment when viewed from above in the vertical direction) included in the two or more tables and located closer to the two or more tables than a position shifted by 1m from an end of the two or more tables on the side that is least intersected by the other table to the side that is not intersected by the other table at the position where the planes intersect with each other may be defined as the concentration space.
In the case where the tables having the work surface in which the illuminance of the work lamp is greater than that of the base lamp are not arranged continuously and adjacently, but the tables having the work surface in which the illuminance of the work lamp is greater than that of the base lamp are in a single isolated state, when an arbitrary plane intersecting the one table is considered, and when the plane intersects another table other than the one table on at least one side of the one table, a line segment region (a region which appears as a line segment when viewed from above in the vertical direction) on the one table side from the center of the end portion on the one table side of the another table intersecting the plane and the end portion on the one table side of the another table intersecting the plane may be defined as the concentrated space.
In addition, when the tables having the work surface in which the illuminance of the work lamp is greater than that of the base lamp are not arranged continuously and adjacently but the tables having the work surface in which the illuminance of the work lamp is greater than that of the base lamp are in a single isolated state, when an arbitrary plane intersecting the one table is considered, and when the plane does not intersect another table other than the one table on at least one side of the one table, a line segment area on the one table side (an area where the line segment appears when viewed from above in the vertical direction) may be defined as the concentrated space, the line segment area being located closer to the one table than a position shifted by 1m from an end portion on the side where the one table is least intersected with the other table to the side where the one table is not intersected with the other table.
< non-focused space (relaxed space, co-created space) >
The non-concentration space may also be defined as follows. More specifically, when two or more tables having work surfaces on which the illuminance of the work lamp is lower than that of the base lamp are disposed in series and adjacent to each other, one table included in the two or more tables and facing the other table via the plane is determined when an arbitrary plane intersecting at least one of the two or more tables among planes including the vertical direction is considered and the plane intersects the other table other than the two or more tables on at least one side of the two or more tables. Then, a line segment area (an area that appears as a line segment when viewed from above in the vertical direction) on the one table side from the center of the end portion on the other table side of the one table where the plane intersects with the end portion on the one table side of the other table where the plane intersects with the plane may be defined as the non-concentration space.
In addition, when two or more tables having a working surface with the illuminance of the working lamp lower than that of the base lamp are arranged in a continuous and adjacent manner, when considering an arbitrary plane intersecting at least one of the two or more tables among planes including the vertical direction, in the case where the plane does not intersect with any other table other than the two or more tables on at least one side of the two or more tables, a line segment area (an area that appears as a line segment when viewed from above in the vertical direction) included in the two or more tables and located closer to the two or more tables than a position shifted by 1m from an end of the two or more tables on the side that is least intersected by the other table to the side that is not intersected by the other table at the position where the planes intersect with each other may be defined as the non-concentration space.
In the case where the tables having the work surface in which the illuminance of the work lamp is lower than that of the base lamp are not arranged continuously and adjacently, but the tables having the work surface in which the illuminance of the work lamp is lower than that of the base lamp are in a single isolated state, when an arbitrary plane intersecting the one table is considered, and when the plane intersects another table other than the one table on at least one side of the one table, a line segment region (a region which appears as a line segment when viewed from above in the vertical direction) on the one table side from the center of the end portion on the one table side of the another table intersecting the plane and the end portion on the one table side of the another table intersecting the plane may be defined as the non-concentration space.
In addition, when the tables having the work surface in which the illuminance of the work lamp is lower than that of the base lamp are not arranged continuously and adjacently but the tables having the work surface in which the illuminance of the work lamp is lower than that of the base lamp are in a single isolated state, when an arbitrary plane intersecting the one table is considered, and when the plane does not intersect another table other than the one table on at least one side of the one table, a line segment area (an area which appears as a line segment when viewed from above in the vertical direction) on the one table side of the one table may be defined as the non-concentrated space, compared to a position shifted by 1m from an end portion on the side where the one table is least at the intersection with the other table.
(specific control capable of achieving the object of the present disclosure)
In this item, an example of specific control in which the division of the centralized working space control area and the non-centralized working space control area is flexibly and quickly performed in order to meet the demand for the centralized working space control area and the non-centralized working space control area will be described. Fig. 5 is a flowchart for explaining an example of control for expanding or reducing the concentrated task space control region and reducing or expanding the non-concentrated task space control region based on a human demand, and is a flowchart for explaining switching control of scenes 1 and 2 (see fig. 2) performed by the control device 61 based on a human demand.
Referring to fig. 5, the environment control system 10 is installed in the ABW office 20, and when the operation of the environment control system 10 is started, the control starts, and in step S1, the control device 61 performs dimming and toning control on the base lamp 3 and the task lamp 5 to reproduce the scene 1. Thereafter, the process proceeds to step S2, and the control device 61 determines whether or not (the number of die sensors whose face in the centralized control mode is desired to face upward)/(the number of tables having work faces included in the centralized work space control area) is equal to or less than a first predetermined value. The number of tables may be set by the user by storing the number in the control device 61 or the arithmetic unit in advance, or the number may be automatically counted by sensing or the like and stored in the control device 61 or the arithmetic unit.
Here, the (number of die sensors whose face desired to be in the collective control mode is directed upward)/(number of tables having work faces included in the collective work space control area) determined by the control device 61 is an example of the first person occupancy amount, and the first predetermined value is an example of the first person occupancy threshold. In embodiment 1 in which the number of all die sensors included in the environment control system 10 is 14, the first predetermined value may be set to 4/14 being 2/7 or 3/14, for example.
The first person occupancy may be any value as long as it is calculated based on the number of tables whose work surfaces are included in the centralized work space control area and the number of persons who are considered to be using the work surfaces located in the centralized work space control area, which are specified from the information from the sensor devices, and may be, for example, (the number of tables having work surfaces included in the centralized work space control area)/(the number of dice sensors whose surfaces are expected to face upward in the centralized control mode), or the like.
If a negative determination is made in step S2 and the control device 61 determines that the demand for the collective work space is high, the control returns to repeat the steps from step S1 onward. On the other hand, when an affirmative determination is made in step S2, the process proceeds to step S3, and the control device 61 determines whether or not (the number of die sensors whose face in the non-centralized control mode is desired to be directed upward)/(the number of tables having work faces included in the non-centralized work space control area) is equal to or less than a second predetermined value. Here, the (number of die sensors whose face desired to be in the non-centralized control mode is directed upward)/(number of tables having work faces included in the non-centralized work space control area) determined by the control device 61 is an example of the second person occupancy amount, and the second predetermined value is an example of the second person occupancy threshold. In example 1, the second predetermined value may be set to 3/14-2/7 or 2/14-1/7, for example.
The second person occupancy amount may be any value as long as it is calculated based on the number of tables whose work surfaces are included in the non-centralized work space control area and the number of persons who are considered to be using work surfaces located in the non-centralized work space control area, which are determined based on information from the sensor devices, and may be (the number of tables having work surfaces included in the non-centralized work space control area)/(the number of dice sensors whose non-centralized control mode is desired to face upward), for example.
If an affirmative determination is made in step S3 and the control device 61 determines that the demand for the non-collective work space is low, the control device 61 determines that the scene change is not necessary, and returns the control to repeat the steps from step S1 onward. On the other hand, when a negative determination is made in step S3, the process proceeds to step S4, and the control device 61 determines that the range of the spatial control region for non-concentrated jobs is insufficient for the need of the non-concentrated control mode, and switches scene 1 to scene 2. As shown in fig. 2, in scene 1, the desk group 1 having 8 desks D07-D14 becomes a concentrated space, while the desk group 1 having 6 desks D01-D06 becomes a non-concentrated space. On the contrary, in scene 2, the desk group 1 having 8 desks D07 to D14 becomes a non-concentrated space, and the desk group 1 having 6 desks D01 to D06 becomes a concentrated space. Accordingly, by switching the scene 1 to the scene 2, the non-collective work space control area can be enlarged and the collective work space control area can be reduced, and the demand of a person can be flexibly and quickly met.
In step S5 subsequent to step S4, the control device 61 determines whether or not (the number of die sensors whose face in the centralized control mode is desired to face upward)/(the number of tables having work faces included in the centralized work space control area) is greater than the first predetermined value. When a negative determination is made in step S5, the control device 61 determines that there is not so much need for a convergence space, returns to step S4 to maintain the reproduction of scene 2, and repeats the steps from step S4 onward.
On the other hand, when an affirmative determination is made in step S5, the process moves to step S6, and the control device 61 determines whether or not (the number of die sensors whose faces in the non-centralized control mode are desired to face upward)/(the number of tables having work faces included in the non-centralized-work space control area) is greater than the above-described second predetermined value. When an affirmative determination is made in step S6, it is determined that the disadvantage of the person using the unconcentrated space becomes large when switching to scene 1, the process returns to step S4 to maintain the reproduction of scene 2, and the steps from step S4 onward are repeated. On the other hand, when a negative determination is made in step S6, the control returns to repeat the steps from step S1 onward.
(Structure and Effect of example 1)
The control and the specific modes of the respective configurations in the environmental control system 10 of embodiment 1 have been described above. In this item, a description will be given of a necessary configuration and an operation effect of the environmental control system 10, and a preferable configuration and an operation effect thereof if employed.
< essential Structure and Effect derived from the Structure >
The environment control system 10 includes: a plurality of task lamps 5 for illuminating the work surfaces (upper surfaces) of the desks D01 to D14 in the ABW office (room) 20 in which a plurality of desks (desks) D01 to D14 are arranged; a plurality of base lamps 3 for illuminating an area in the ABW office 20, which area is larger than the work surface; dice sensors (sensor devices) S1 to S14 that detect at least one of position information of one or more persons present in the ABW office 20, on duty information of one or more persons present in the ABW office 20, and personal information of one or more persons present in the ABW office 20; and a control device 61. Further, the control device 61 performs the following partition control: the plurality of work lamps 5 and the plurality of base lamps 3 are subjected to light and color adjustment control so that a centralized work space control area and a non-centralized work space control area are generated, the centralized work space control area is an area where the illuminance of the work lamps 5 is greater than that of the base lamps 3, and the non-centralized work space control area is an area where the illuminance of the work lamps 5 is less than that of the base lamps 3. In addition, the environmental control system 10 executes one or more of the following controls: when the control device 61 determines that the amount of the concentrated work space control area is small (the size of the concentrated work space control area is small) based on the information from the die sensors S1 to S14, the control device performs light and color adjustment control on the plurality of work lamps 5 and the plurality of base lamps 3 so that the amount of the concentrated work space control area becomes large (the size of the concentrated work space control area becomes large); when the control device 61 determines that the amount of the centralized working space control area is large (the size of the centralized working space control area is large) based on the information from the die sensors S1 to S14, it performs light and color adjustment control on the plurality of work lamps 5 and the plurality of base lamps 3 so that the amount of the centralized working space control area becomes small (the size of the centralized working space control area becomes small); when the control device 61 determines that the amount of the non-centralized working space control area is small (the size of the non-centralized working space control area is small) based on the information from the die sensors S1 to S14, the control device performs dimming and toning control on the plurality of work lamps 5 and the plurality of base lamps 3 so that the amount of the non-centralized working space control area is increased (the size of the non-centralized working space control area is increased); when the control device 61 determines that the amount of the non-collective work spatial control area is large (the size of the non-collective work spatial control area is large) based on the information from the die sensors S1 to S14, the control device performs light and color adjustment control on the plurality of work lamps 5 and the plurality of base lamps 3 so that the amount of the non-collective work spatial control area is reduced (the size of the non-collective work spatial control area is reduced). Here, the "amount" can be defined as a physical amount that can specify a size relationship, and can be defined as a dimensionless amount including the number and the like in the physical amount. Thus, "amount" includes, for example, "size (area)", "number".
According to the present disclosure, at least one of the spatial control region for concentrated work and the spatial control region for non-concentrated work can be enlarged or reduced based on the usage demand of at least one of the spatial control region for concentrated work and the spatial control region for non-concentrated work. Thus, it is possible to realize flexible division that easily copes with work performance of fluidity of workers and organizations and demands for each space generated in a period of every hour, every day, every month, or the like.
< selection of a plurality of preferable configurations and effects derived from the respective configurations >
In the environment control system 10, the control of reducing the size of the non-collective work spatial control region may be performed simultaneously with the control of increasing the size of the collective work spatial control region, or the control of reducing the size of the collective work spatial control region may be performed simultaneously with the control of increasing the size of the non-collective work spatial control region. Further, the amount of the surfactant is preferably within 30 minutes, more preferably within 10 minutes, still more preferably within 1 minute, and most preferably within 10 seconds. This is because, in the case of 30 minutes or less, layout change can be achieved quickly enough compared to general layout change involving transportation or rearrangement of daily appliances and furniture, and labor can be saved. In addition, this configuration is not essential, and may not be executed, and for example, only the control of increasing the amount of the spatial control region for collective work (enlarging the size of the spatial control region for collective work) or only the control of decreasing the amount of the spatial control region for collective work (reducing the size of the spatial control region for collective work) may be executed by using the method described in detail above. Alternatively, only the control for increasing the amount of the non-collective work spatial control region (increasing the size of the non-collective work spatial control region) may be performed by the method described in detail above, or only the control for decreasing the amount of the non-collective work spatial control region (decreasing the size of the non-collective work spatial control region) may be performed. That is, for example, only the control of increasing or decreasing the amount of the spatial control region for concentrated work may be performed without performing the control of changing the amount of the spatial control region for non-concentrated work. On the contrary, the control of increasing or decreasing the amount of the non-collective work spatial control region may be performed only without changing the amount of the collective work spatial control region.
According to this configuration, when the size of the room is small, the allocation of the centralized working space control area and the non-centralized working space control area can be performed efficiently.
The control device 61 may execute the light/color adjustment control based on the calculation result information of the calculation unit 61c that performs at least one of the determination of whether or not the amount of the working space control areas for concentrated work (the size of the space control areas for concentrated work) is appropriate by comparing the first person occupancy amount calculated based on the number of the persons whose working surfaces are included in the space control areas for concentrated work and the number of the persons who are considered to be using the working surfaces located in the space control areas for concentrated work determined based on the information from the dice sensors S1 to S14 with the first person occupancy threshold value and the determination of whether or not the amount of the space control areas for non-concentrated work (the size of the space control areas for non-concentrated work) is appropriate by comparing the second person occupancy amount with the second person occupancy threshold value, the second person occupancy amount is calculated based on the number of desks D01 to D14 whose work surfaces are included in the non-centralized-work space control area and the number of persons who are considered to be using the work surfaces located in the non-centralized-work space control area determined from the information from the dice sensors S1 to S14.
According to this configuration, at least one of the demand for the centralized working space control area and the demand for the non-centralized working space control area can be objectively determined.
[ example 2]
In embodiment 1, the case where the dice sensors S1 to S14 are used to switch scenes with good responsiveness to the demand of a person has been described, but the scenes may be switched only for a predetermined period. For example, although the illumination may be dimmed during noon break in an office or the like, the scene from the morning and after noon break to 4 pm may be switched when the operating lamp 5 and the base lamp 3 are turned on after noon break. In this case, for example, each person who uses the ABW office 20 from the afternoon may transmit desired information of a pattern from the afternoon to a control device that directly performs dimming and toning control, an operation terminal configured by other information devices such as a tablet pc and a smartphone, a workstation on the cloud, a server, and the like in the morning by any method described in the above column of the sensor device, receive a signal directly from the sensor device, or select an optimal scene based on the information by the control device that receives a signal from the information device. Note that, although embodiment 1 shows a mode in which the control device performs calculation and determination of a demand for office space for the sake of brevity, the configuration intended by the present application is not essential. That is, although not particularly shown, it should be understood that the part for performing the calculation and determination may be included in, for example, a cloud server having a CPU, another personal computer, or a tablet computer, and any method may be selected.
In addition, in embodiment 1, the partitioning is performed only by the dimming and toning control of the work lamp 5 and the base lamp 3, but the partitioning may be performed by the output of sound in addition to the dimming and toning control of the work lamp 5 and the base lamp 3.
In embodiment 2, a case where scenes are switched only for a predetermined period and also the division is performed using the acoustic effect is described.
Fig. 6 is a layout configuration diagram corresponding to fig. 1 in the environment control system 110 of embodiment 2. Fig. 7 is a block diagram corresponding to fig. 3 in the environment control system 110 according to embodiment 2. As shown in fig. 6, the environmental control system 110 is different from the environmental control system 10 of embodiment 1 in that a plurality of speakers 109 (e.g., LSPX-103E 26: sony) are mounted on the lamp rail 104. The difference is that instead of using the dice sensors S1 to S14, an information reading device 88 for reading a desired pattern registered in advance in a mobile phone (smartphone) is used as the sensor device. The information reading device 88 is installed around the entrance of the ABW office 120, for example.
As shown in fig. 7, in embodiment 2, the control device 161 of the environment control system 110 includes a sound signal transmitting unit 161d in addition to the control unit 161a, the light/color adjustment signal transmitting unit 161b, and the computing unit 161c, and outputs a signal including sound information to be output to the plurality of speakers 109. Unlike the case shown in fig. 7, the sound control unit of the environment control system 110 may be built in an information device (for example, an operation terminal, a workstation on the cloud, or a server) outside the control device 161 that directly performs the dimming/toning control, and more specifically, may be built in a personal computer, a tablet computer, a smartphone, a single board computer, or the like.
To describe the sound effects of the plurality of speakers 109 in more detail, as shown in fig. 6, in the environment control system 110, 4 first speakers 109a to fourth speakers 109d are mounted on the light rail 104, and the speakers 109a to 109d are wirelessly connected in stereo. The first speaker 109a and the second speaker 109b constitute a speaker group 1, and the third speaker 109c and the fourth speaker 109d constitute a speaker group 2. The first speaker 109a and the second speaker 109b belonging to the speaker group 1 output the same first sound content, and the third speaker 109c and the fourth speaker 109d belonging to the speaker group 2 output the same second sound content. The first speaker 109a and the second speaker 109b belonging to the speaker group 1 output sounds to a person existing in the area of the desk group 1, and the third speaker 109c and the fourth speaker 109d belonging to the speaker group 2 output sounds to a person existing in the area of the desk group 2. The number of speakers belonging to the speaker group 1 may be any number, and the number of speakers belonging to the speaker group 2 may be any number. Further, as the speaker 109, a directional speaker, for example, a parametric speaker or the like may be used. In the parametric speaker, since ultrasonic waves are used, the output direction of sound can be made to have a significant directivity.
In the above configuration, for example, sound content obtained by recording the sound of the rippling of a brook is reproduced from the speaker group 1 located at the upper part of the desk group 1 via a smartphone. Meanwhile, sound contents obtained by recording jazz music or bosanova music are reproduced from the speaker group 2 located at the upper part of the desk group 2 via a smartphone different from the smartphone described above. When sitting on a desk belonging to the desk group 1, the gurgle of the brook is heard, while the jazz music and bosanova music are heard only a little. On the other hand, when sitting on a desk belonging to the desk group 2, jazz/bosanova music was heard, while the rippling of the creek heard only a little. As described above, for example, it is possible to confirm that: with such a configuration, different contents can be selectively provided to some extent in units of different desk groups.
In example 2, the scene setting shown in fig. 8 is performed, and the respective scenes are reproduced by performing the light and color adjustment control of the task lamp 5 and the base lamp 3 in addition to the audio output from the speaker group 1 and the speaker group 2. Information on the sound output from each lighting device in each scene is stored in the storage unit 161e in advance. For example, when the above-described scene 1 is reproduced as the illumination control in addition to the audio output from the speaker group 1 and the speaker group 2, the effect of the ease of improving the efficiency of the intensive work by the illumination described in the scene 1 in example 1 is superimposed on the effect of the ease of improving the efficiency of the intensive work by the audio of the rippling water of a creek in the desk group 1. Thus, by the additive effect of the superimposition, the region of the desk group 1 can be changed to a region that is easy to greatly improve the efficiency of the collective work.
The rippling water noise of the creek has characteristics close to those of a sound having intensity in the entire frequency region, which is called white noise or brownian noise. When the characteristic is expressed as a frequency-intensity fourier transform spectrum by a curve, the frequency characteristic of the sound in the curve of the characteristic is wider than that of a curve of a frequency-intensity fourier transform spectrum having no intensity over the entire frequency range, for example, a curve of a frequency-intensity fourier transform spectrum of a specific musical scale of a piano. As described more precisely, in the partition control, the spectrum width in the fast fourier transform of the sound outputted at the maximum sound volume in the collective operation spatial control area may be wider than the spectrum width in the fast fourier transform of the sound outputted at the maximum sound volume in the non-collective operation spatial control area. Here, the spectral width refers to a spread width of a wavelength or a frequency of a spectral line, and is a difference in wavelength between two wavelengths whose intensity falls below a predetermined width (for example, 1/2, 1/10, or the like) from a maximum value, and may be expressed by a frequency. The spectral width at half maximum (in the spectral distribution of the light output, the width of a wavelength at which the relative emission intensity is 50% of the peak) may be used to define the spectral width. The sound having this characteristic has the following remarkable action effects: it is easy to eliminate noises, such as rattles, speech sounds, etc., having various frequencies and coming from places other than the desk group 1, which may reduce the efficiency of the concentrated work, as compared with sounds having a tendency not to have intensity in the frequency region. Thus, the worker who works using the desk group 1 does not easily hear the extraneous noise. This makes it possible to set the region of the desk group 1 to a region where it is easier for the worker to concentrate on the work and to bury the work.
As the content of the sound capable of improving the efficiency of the collective operation, a content close to the above-described characteristics called white noise and brownian noise is preferable, but the content is not particularly limited thereto. For example, the content may be mainly natural environmental sounds such as bird singing, leaf rubbing sounds of forests, and sea waves, or the music may be mainly electronic sounds obtained by waveform synthesis using a synthesizer for music or the like. The audio content may be a content obtained by recording natural sound as it is, a content obtained by composing a song by a person, or a content obtained by composing a song by a computer algorithm, AI, or artificial intelligence. The audio content may be a mixture of the above plural kinds of audio.
On the other hand, since the scene 1 is reproduced in addition to the output of the audio contents obtained by reproducing the music of jazz and bosanova in the existing region of the desk group 2, as described in embodiment 1, the effect of easily promoting relaxation by illumination with the illumination light having a low color temperature and the effect of easily promoting relaxation by a plurality of people and the effect of easily promoting smooth communication by jazz and bosanova are superimposed. Thus, the region of the desk group 2 can be set as a region in which the worker can be greatly relaxed and smooth communication of a plurality of people is remarkably easily achieved by the complementary effect obtained by the superimposition.
Jazz/bosanova music has the following characteristics: the frequency characteristics of sound in a fourier transform spectrum curve of frequency versus intensity are not broad as compared with the white noise and the brown noise described above. This is caused by the fact that instruments such as pianos, saxophones, and bass which are played mainly with jazz and bosanwa are used in a state of being strictly tuned so as to output sounds of a specific single scale, that is, do, re, mi, fa, sol, la, si, do, and chromatic scales thereof. Therefore, although the function of eliminating the noise against the extraneous noise described above is likely to be insufficient, the need for the function of eliminating the noise is not great in the shared space where relaxation is originally intended and communication by a plurality of persons is performed, and therefore, even if the function of eliminating the noise is insufficient, a large adverse effect is not generated.
Also, jazz, bosanow, and the like are sound contents that are preferably provided in cafes and relaxation facilities, and are frequently used in the case of promoting relaxation and smooth communication of many people. Therefore, it is obvious from this that if these sound contents are used, the worker can feel a sense of relaxation and a sense of calm, and can realize smooth communication.
As contents of sounds that can promote relaxation and smooth communication by a plurality of people, contents having characteristics close to those of what are called jazz and bosanow are preferably used, but the contents are not particularly limited thereto. For example, as the content of the sound that can promote relaxation and smooth communication by a plurality of people, classic music, music for curing soul, natural environment sound, and the like may be used. Such audio content may be obtained by recording natural sounds as they are, by composing a song by a person, or by composing a song by a computer algorithm, AI, or artificial intelligence. The audio content may be a mixture of the above plural kinds of audio.
As is clear from the above description, it is preferable that the illumination control and the sound control are linked, and it is more preferable that the illumination and the sound content that can be dominantly provided to each desk group coincide with each other. By superimposing the effects of the intended subject matter of each desk group in this way, complementary effects can be produced, and the effects of the intended subject matter of each desk group can be made remarkable.
In addition, when the lighting control is linked to the audio control, the operations thereof do not need to be strictly synchronized, and for example, even if the start time or end time of the scene switching of the lighting and the start time or end time of the switching of the audio content are slightly different, the above-described operation and effect are not lost. When such a deviation occurs, the time of the deviation between the start time or end time of the scene switching of the lighting and the start time or end time of the switching of the audio content may be any time, but is preferably within 30 minutes, more preferably within 10 minutes, even more preferably within 1 minute, and most preferably within 10 seconds. When the time of the deviation is within 30 minutes, the layout change can be performed quickly enough compared to the layout change accompanied with the transportation or resetting of general daily appliances or furniture, and the layout change can be performed with less labor.
< evaluation results of illuminance and volume of space in scene 1 >
Next, one test result of the illuminance and volume of the space in the scene 1 will be described. Fig. 9 is a schematic diagram illustrating information of irradiation light irradiated by each of the lighting devices 3 and 5 and information of sound output by each of the speakers 109a to 109d when sound is output and scene 1 is reproduced in embodiment 2. Fig. 10 is a diagram showing the results of a test example in which an illuminance meter (CL-200: konica minolta) and a noise meter (SD-2200: FUSO) disposed so as to straddle D03 from the desk D12 were used to measure the illuminance and sound volume of a space when reproducing scene 1 in the ABW office 120 of example 2. In fig. 10, y1 is a function relating to illuminance, and y2 is a function relating to sound volume.
As shown in fig. 10, in the present test example, the illuminance and the volume are minimum with respect to the passage provided between the desk group 1 and the desk group 2. Also, illumination of different illumination lights and reproduction of different sound contents are performed on both sides of the aisle. In addition, in the desk group 1, illumination light in which the illuminance sharply increases locally on the desk surface can be realized. In addition, in the desk group 1, audio contents which promote human concentration are reproduced with a large volume, and in the desk group 2, audio contents which provide a sense of relaxation and a sense of calm to a human are outputted with a volume which is about half the volume outputted in the desk group 1. Therefore, in the present test example, the peripheral region of the desk group 1 and the peripheral region of the desk group 2 can be clearly separated (divided), and excellent zoning can be achieved. Further, by the illumination light and sound contents respectively reproduced in the peripheral area of the desk group 1 and the peripheral area of the desk group 2, the peripheral area of the desk group 1 can be set as an excellent space for concentration in which a person is particularly apt to concentrate on a job, and on the other hand, the peripheral area of the desk group 2 can be set as a space for co-creation in which a person is particularly apt to feel relaxed and which is excellent also in that a plurality of persons communicate.
Further, the output of the sound of the present disclosure is not to provide the person with favorite music to improve the performance of the person, and it is not possible to provide the person with the sound using earphones, headphones. This is because, even if a person is provided with sound using headphones or headphones, the region cannot be divided.
Next, the timing of scene change in example 2 will be described. In embodiment 2, each person who uses the ABW office 120 at a specific date and time (for example, in the afternoon of thursday) sets one of 3 options, that is, the setting of the collective work space, the setting of the non-collective work space, or the setting of no pattern, in advance, in the operation terminal, using an application of the operation terminal (for example, a mobile phone such as a tablet pc or a smartphone) of the person. Then, before the arrival of the specified date and time, the operation terminal is brought close to the information reading device 88, information for specifying the person, the selected pattern, and the specified date and time at which the desired pattern is to be realized is read by the information reading device 88, and the information is transmitted to the control device 161 in a state in which the information is associated.
Further, when it is immediately before the specific date and time (for example, when the specific date and time is thursday afternoon, it is immediately before the specific date and time is thursday morning), the control device 161 calculates, based on the information, (the number of persons desiring the centralized control mode)/(the number of tables having work surfaces included in the centralized work spatial control area), and (the number of persons desiring the non-centralized control mode)/(the number of tables having work surfaces included in the non-centralized work spatial control area).
Then, it is determined whether or not (the number of persons desiring the centralized control mode)/(the number of tables having work surfaces included in the centralized-work spatial control area) is equal to or greater than a third predetermined value, and whether or not (the number of persons desiring the non-centralized control mode)/(the number of tables having work surfaces included in the non-centralized-work spatial control area) is equal to or greater than a fourth predetermined value.
When the number of people desiring the centralized control mode)/(the number of tables having work surfaces included in the centralized-job spatial control area) is equal to or greater than the third predetermined value and the number of people desiring the non-centralized control mode)/(the number of tables having work surfaces included in the non-centralized-job spatial control area) is less than the fourth predetermined value, scene 1 is reproduced when a specific date comes.
In addition, when the (number of persons desiring the centralized control mode)/(number of tables having work surfaces included in the centralized-work spatial control area) is lower than the third predetermined value and the (number of persons desiring the non-centralized control mode)/(number of tables having work surfaces included in the non-centralized-work spatial control area) is equal to or higher than the fourth predetermined value, when a specific date comes, scene 2 is reproduced.
In addition, when (the number of persons desiring the centralized control mode)/(the number of tables having work surfaces included in the centralized-job spatial control area) is lower than the third predetermined value and (the number of persons desiring the non-centralized control mode)/(the number of tables having work surfaces included in the non-centralized-job spatial control area) is lower than the fourth predetermined value, scene 1 is reproduced (scene 2 may also be reproduced).
In addition, when (the number of persons desiring the centralized control mode)/(the number of tables having work surfaces included in the centralized-work spatial control area) is equal to or greater than a third predetermined value and (the number of persons desiring the non-centralized control mode)/(the number of tables having work surfaces included in the non-centralized-work spatial control area) is equal to or greater than a fourth predetermined value, scene 1 is reproduced when the number of persons desiring the centralized control mode is greater than the number of persons desiring the non-centralized control mode, whereas scene 2 is reproduced when the number of persons desiring the centralized control mode is less than the number of persons desiring the non-centralized control mode.
In embodiment 2, by controlling the reproduction of the scene in this manner, it is possible to realize flexible zoning that can appropriately cope with the work performance of the fluidity of workers and organizations at a specific date and time in the future and the demand for each space.
Further, (the number of persons desiring the collective control mode)/(the number of tables having work surfaces included in the spatial control area for collective work) is an example of the first required amount, and the third predetermined value is an example of the first required threshold. In addition, (the number of persons desiring the non-centralized control mode)/(the number of tables having work surfaces included in the non-centralized-work space control area) is an example of the second required amount, and the fourth predetermined value is an example of the second required threshold.
The first required amount may be any value calculated based on the number of tables whose work surfaces are present in the centralized work space control area and the number of persons who want to use the work surfaces located in the centralized work space control area, which is specified from the information from the sensor device, and may be, for example, (the number of tables having work surfaces included in the centralized work space control area)/(the number of persons desiring the centralized control mode), or the like. The second required amount may be any value calculated based on the number of tables whose work surfaces are present in the non-centralized-work spatial control area and the number of persons who want to use the work surfaces located in the non-centralized-work spatial control area, which is specified from the information from the sensor device, and may be, for example, (the number of tables having work surfaces included in the non-centralized-work spatial control area)/(the number of persons desiring the non-centralized control mode), or the like.
(preferred structure and effect thereof if adopted in example 2)
As described above, in the environment control system 110 of embodiment 2, the control device 161 executes the light/color adjustment control based on the calculation result information of the calculation unit 161c, which is at least one of the determination of whether the amount of the working space control area for concentrated work (the size of the space control area for concentrated work) is appropriate by comparing the first required amount with the first required threshold value calculated based on the number of tables whose working surfaces are present in the space control area for concentrated work and the number of persons who want to use the working surfaces located in the space control area for concentrated work determined based on the information from the information reading device (sensor device) 88, the second required amount is calculated based on the number of tables whose work surfaces exist in the non-collective work space control area and the number of persons who want to use the work surfaces located in the non-collective work space control area determined based on the information from the information reading device 88.
Therefore, according to this configuration, at least one of the demand for the centralized work space control area and the demand for the non-centralized work space control area can be objectively determined.
The environment control system 110 may further include a plurality of speakers 109 for outputting sound into the ABW office (room) 120. In the partition control, the plurality of speakers 109 may output sounds to the spatial control region for intensive work and the spatial control region for non-intensive work. Further, the spectral width in the fast fourier transform of the sound output at the maximum sound volume in the collectively working space control area may be wider than the spectral width in the fast fourier transform of the sound output at the maximum sound volume in the non-collectively working space control area.
According to this configuration, the effect of easily improving the efficiency of the collective work by the illumination and the effect of easily improving the efficiency of the collective work by the sound can be superimposed, and the spatial control area for the collective work can be changed to the area of easily remarkably improving the efficiency of the collective work by the complementary effect of the superimposition. In the non-collective work spatial control region, the effect of easily improving the sense of relaxation and promoting communication by lighting and the effect of easily improving the sense of relaxation and promoting communication by sound can be superimposed. Thus, the superimposed complementary effect can change the non-collective work spatial control region to a region in which a sense of relaxation is particularly likely to be felt and communication is particularly likely to be performed.
Further, one or more speakers may be provided to output sound to the room, and at least one of the volume of the speaker and the content output from the speaker may be controlled based on the calculation result information of the calculation unit. Here, the one or more speakers may be configured to output the sound only to one of the centralized working space control region and the non-centralized working space control region, or may be configured to: the environment control system includes a plurality of speakers, and the plurality of speakers can output sounds to both the spatial control region for intensive work and the spatial control region for non-intensive work. As is clear from the above description, if the configuration of the present modification is adopted, it is possible to highlight the difference in the areas different from each other by the sound output from the speaker.
(case where scene is not set in advance)
In addition, unlike the cases described in embodiment 1 and embodiment 2, the scenes may not be registered in advance in the storage unit of the control device. Further, the control device may be configured to generate the spatial control regions for concentrated work and the spatial control regions for non-concentrated work with a higher degree of freedom by performing dimming/toning control independently for one or more work lamps and one or more base lamps or performing dimming/toning control for each group based on information from the sensor device.
(regarding the number of the spatial control regions for collective work and the spatial control regions for non-collective work)
In embodiment 1 and embodiment 2, the case where there is one centralized work space control area and one non-centralized work space control area is described. However, the centralized working space control area may be composed of two or more portions arranged to be dispersed with each other, and the non-centralized working space control area may be composed of two or more portions arranged to be dispersed with each other. In the case where both the centralized working space control area and the non-centralized working space control area are configured by two or more parts that are arranged in a distributed manner, the number of the parts that are connected to each other to configure the centralized working space control area and are arranged in a distributed manner may be the same as or different from the number of the parts that are connected to each other to configure the non-centralized working space control area and are arranged in a distributed manner. Here, in the partition of the present disclosure, it is preferable to collectively change the entirety of the respective portions (islands) to the collective work space control area or the non-collective work space control area. In association with this description, in the technique of the present disclosure, the partition is performed based on information of the sensor device, that is, at least one of position information of one or more persons present in the room, on-duty information of one or more persons present in the room, and personal information of one or more persons present in the room. Therefore, it is needless to say that the technique of the present disclosure does not include a technique of changing the work surface corresponding to the seat to the centralized work space control area or the non-centralized work space control area for each seat according to the individual intention.
