Space control system

Technical Field

The present disclosure relates to a space control system, and more particularly, to a space control system suitable for an Activity based office (ABW) office, a fixed-station-less office.

Background

In recent years, an operation method called ABW, in which a workplace is selected according to the operation contents, has attracted attention, and an office in which ABW is introduced (ABW office) is emerging. The ABW office is an office that performs a space design for preparing a space suitable for the work content according to the work content of the employee, thereby improving the performance of the organization. In the ABW office, space design for the purpose of, for example, easily concentrating on a work space for each work, a shared space for sharing knowledge, and the like is performed by changing the brightness, light color, and the like of illumination.

In addition, there is also known a no-fixed-station office designed so that employees do not have fixed seats and can freely change the seats on which they sit to perform work. For example, patent document 1 discloses a system related to an office without fixed stations. The system disclosed in patent document 1 has: an entrance/exit management unit that counts the number of persons present in an office; an office area determination unit that determines an office area based on the counted number of persons present; and an equipment control unit that controls equipment corresponding to an area other than the determined office area to be stopped.

Disclosure of Invention

Problems to be solved by the invention

One of the introduction purposes of the ABW office and the non-fixed-station office is to activate communication by changing a person who wants to communicate by changing the seating position of an employee. However, since each person has a preference for a place and a preference for an environment, each employee uses only a preferred specific seat, and it is sometimes difficult to activate communication.

In a modern society where breakdown of local communities, increase in elderly people living alone, and the like are regarded as problems, it is important to activate communication in addition to workplaces.

An object of the present disclosure is to provide a space control system capable of realizing activation of communication between facility users in a facility divided into a plurality of areas.

Means for solving the problems

A space control system according to an aspect of the present disclosure is a space control system applied to a facility divided into a plurality of areas, including: a space control device provided in each of the plurality of areas, the space control device controlling a space environment of each of the areas; and a control device that sets different control parameters for each of the space control apparatuses in each of the plurality of areas to control the space control apparatus. The space control device is at least one device selected from a lighting device, an air conditioning device, a fragrance device, an audio device, and a video device, and the control device is configured to: replacing the control parameter of the spatial control device of one of the plurality of areas with the control parameter of the spatial control device of the same kind of the other area.

ADVANTAGEOUS EFFECTS OF INVENTION

According to the space control system of the present disclosure, it is possible to activate communication between facility users in a facility divided into a plurality of areas. By introducing the system according to the present disclosure into an ABW office, a no-fixed-station office, or the like, for example, the number of employees who always use a specific seat can be reduced. Therefore, the person who wants to communicate changes, and it is possible to activate communication, improve work performance, and activate organization.

According to the lighting system of the present disclosure, it is possible to realize effective zoning that easily copes with the demand for each space and the fluid performance of employees and organizations that occur in cycles such as hourly, daily, monthly, and the like.

Detailed Description

Next, an example of an embodiment of a space control system according to the present disclosure will be described in detail with reference to the drawings. However, the space control system of the present disclosure is not limited to the embodiments described below. It is also conceivable from the beginning to selectively combine the components of the embodiments described below.

The main body of the apparatus and system of the present disclosure is provided with a computer. The computer realizes the functions of the main body of the apparatus and system of the present disclosure by executing the program. A computer includes a processor that operates according to a program as a main hardware configuration. The processor may be any processor capable of executing the program to realize the above-described functions, regardless of the type thereof. The processor is constructed using one or more circuits including Integrated Circuits (ICs) or large scale integrated circuits (LSIs). The plurality of circuits may be integrated in one chip or may be provided in a plurality of chips. The plurality of chips may be integrated in one device or may be provided in a plurality of devices. The program is stored in a non-transitory storage medium such as a computer-readable ROM, an optical disk, and a hard disk drive. The program may be stored in advance in a storage medium, or may be supplied to the storage medium via a wide area communication network including the internet or the like.

Next, the space control system 10 as an example of the embodiment will be described in detail with reference to fig. 1 to 3. In an office 100 to which the space control system 10 is applied, fig. 1 is a diagram showing a first illumination mode, and fig. 2 is a diagram showing a second illumination mode. Fig. 3 is a block diagram showing the structure of the space control system 10. In fig. 1 and 2, the differences in the illumination environments in the

areas

1, 2, 3 are represented by the differences in the density of the dot-and-dash lines.

The space control system 10 according to the embodiment is a system for activating communication between employees in a workplace, but the system according to the present disclosure is not limited to this. The space control system according to the present disclosure can be applied to facilities other than a workplace, which are divided into a plurality of areas, such as senior citizens 'facilities, citizens' houses, libraries, and rental houses.

The office 100 to which the space control system 10 is applied is an office divided into a plurality of areas. Three

regions

1, 2, and 3 are illustrated in fig. 1 and 2, but the number, size, and the like of the regions are not particularly limited. The

areas

1, 2, and 3 are areas to be subjected to spatial environment control by the spatial control system 10, and are located on the same floor of the same building, for example, and are arranged to be able to see the environment of each area. Each of the

areas

1, 2, and 3 is controlled to have a different spatial environment from the other areas by the spatial control system 10, and is controlled to have the same spatial environment in each area. In the examples shown in fig. 1 and 2, the lighting environment is different in the

areas

1, 2, 3.

The

areas

1, 2, and 3 may be installed on other floors or other buildings, for example, as long as there is a possibility that employees can confirm the environmental conditions of each area and can freely use the business system of each area according to the work content and the like. When the

areas

1, 2, and 3 do not exist on the same floor, it is preferable to use a system, a display, or the like having a GUI (Graphical User Interface) or the like so that the employee can easily check the environmental conditions on each floor.

The office 100 to which the space control system 10 is applied is an office designed such that an employee does not have a fixed seat and can freely change the seated seat to perform work according to work content or the like. An example of an office 100 is an ABW office, a stationary office. It is expected that the space control system 10 will cause confusion and dissatisfaction of employees if applied to offices where employees have fixed seats and the space environment is changed in a short period of 1 day or 1 week as will be described later. On the other hand, the ABW office and the non-fixed-station office are offices in which employees can freely move to their favorite areas, and are therefore suitable as facilities to which the space control system 10 is applied.

As illustrated in fig. 1 and 2, a copying machine 5 is provided in the area 1, a bookshelf 6 is provided in the area 2, and a vending machine 7 is provided in the area 3. That is, the office 100 includes different stationary devices in each of the plurality of

areas

1, 2, and 3. The fixed equipment is generally equipment whose position is fixed for a long period of time such as 1 year or 5 years (a period of time significantly longer than a predetermined period of time described later in the alternative space environment), or equipment which cannot be moved in terms of the structure of facilities. As will be described in detail later, the space control system 10 can activate communication by using stationary equipment that is strongly related to the preference of the space environment of a person and the preference of a place.

Examples of the stationary devices include a copier 5 (which may be a multifunction machine having functions of a printer, a scanner, and the like), a bookshelf 6, a vending machine 7, a FAX, a shredder, a table, a chair, a compartment, a locker, a refrigerator, a water dispenser, a coffee maker, and the like. The fixing devices present in the respective areas may be structures such as windows, floors, ceilings, walls, and the like. The fixed equipment is equipment that cannot control the brightness, temperature, smell, sound, image, and the like of the

areas

1, 2, and 3 to arbitrarily change the spatial environment of each area.

In addition, it is expected that, in a case where the office 100 has different fixed facilities in the vicinity of each of the

areas

1, 2, and 3, the presence of the fixed facilities greatly affects the selection of the

areas

1, 2, and 3 by the staff. As the fixed equipment outside the area, a toilet, a meeting room, a corridor, a resting room, a smoking room, a hot water room, and the like can be cited. For example, when the area 1 is close to a toilet, the area 2 is close to a conference room, and the area 3 is close to a smoking room, it is expected that employees having a high smoking frequency prefer the area 3. Even if there are no different fixed facilities in the

areas

1, 2, and 3 or their vicinities, the positional relationship of the areas and the like may affect the area selection of the employee.

As illustrated in fig. 3, the space control system 10 includes a space control device such as the lighting device 11, and a control apparatus 20 that sets different control parameters for each of the plurality of

areas

1, 2, and 3 to control the space control device. The space control device is a device that is provided in each of the plurality of

areas

1, 2, and 3 to control the space environment of each area. In the example shown in fig. 1 and 2, in each of the

areas

1, 2, 3, a lighting apparatus 11 is provided as a space control apparatus. The control device 20 is configured to: and replacing the set control parameters of the space control equipment with the control parameters of the same kind of space control equipment of other areas to replace the space environment of the plurality of areas.

The employee having high environmental preference is an employee having higher preference for at least one parameter of at least one of the space control devices (the lighting device 11, the air-conditioning device 12, the fragrance device 13, the audio device 14, and the video device 15) than preference for fixed devices inside and outside the area, and the parameter is a factor for determining the seating position. On the other hand, a user with high preference for a place is an employee who has higher preference for a specific stationary device inside and outside the area than preference for all parameters of all the space control devices (the lighting device 11, the air-conditioning device 12, the fragrance device 13, the audio device 14, and the video device 15) and who is a factor of determining the seating position.

As will be described in detail later, the control device 20 replaces the control parameters such as the output and the color temperature set for each of the lighting devices 11 in each of the

areas

1, 2, and 3 with the control parameters of the lighting devices 11 in the other areas every predetermined period such as 1 day and 1 week. Thereby, the lighting environment of the

areas

1, 2, 3 is replaced. By replacing the lighting environment, it is possible to promote the movement of employees having high environmental preference and reduce the number of employees who always use a specific seat. On the other hand, it is expected that even an employee highly preferred in a place where the lighting environment changes does not move to another area, and therefore, a person who wants to communicate changes, and communication can be activated.

In this case, since communication can be activated without imposing a pressure on a user having a high preference for places to leave a place that is usually preferred, the burden on the user can be reduced more easily than in a system and an operation method in which seats are forcibly selected for all users who work in an office by using darts, wheels, or the like at the time of attendance, for example.

When the control parameter is replaced, the parameter may be replaced in the same state without being changed, but the parameter may be changed if the parameter change range is a range within a category that is substantially the same. For example, the light source colors of the illumination apparatus are classified into 5 categories of "warm white (2600K to 3250K)", "white (3250K to 3800K)", "cold white (3800K to 4500K)", "neutral white (4600K to 5500K)", "daylight color (5700K to 7100K)" (jis z9112: 2012). If the color is within this category, the perceived color does not change significantly, and the seat position determination is not easily affected, so that the parameters may change within the same category when the parameters are replaced. The parameter may be varied not only by a variable such as color temperature but also by a qualitative variable such as music content. In the case of music content, even if each music piece is different music pieces, if the music style is the same, such as jazz, classical, and technical dance, and the composer and singer are the same, the impression felt from the music pieces does not greatly change and does not affect the seat position determination, and therefore, the parameters can be changed within the same category at the time of parameter replacement.

In addition, in the case of replacing the control parameters, if the control parameters are within a range that does not substantially affect the seat position determination, it is not necessary to replace the control parameters of all the control devices in each area. For example, it is assumed that 50 identical lighting devices exist in each of the

regions

1, 2, and 3, and the replacement control parameter is a color temperature. Even if the color temperature of each of the 5 devices in each area is not replaced, the perceived impression of space does not change significantly and does not affect the seat position determination, and therefore, if the color temperature is within a range that does not affect the seat position determination, it is not necessary to replace the control parameters of all the control devices in each area.

The space control system 10 includes at least one device selected from the group consisting of a lighting device 11, an air conditioning device 12, a fragrance device 13, an audio device 14, and a video device 15 as a space control device. In the space control system 10, since the control parameters of the space control devices are replaced between the

areas

1, 2, and 3 every predetermined period, at least one space control device of the same type is provided in each area. In the example shown in fig. 1 and 2, a lighting fixture 11 is provided in each region.

The space control system 10 may include a camera 30 as a sensor for acquiring information on the states of the

areas

1, 2, and 3. The cameras 30 are provided in, for example, each of the

areas

1, 2, and 3. The control device 20 may be configured to measure the number of workers per area from the image of the camera 30 and change the area of each area based on the measured value. Specifically, the area of the region with fewer people is reduced and the area of the region with more people is enlarged. Instead of or in addition to the camera 30, other sensors such as a scanner in an indoor position information System called a Local Positioning System (LPS), a Laser sensor in a Laser-based Ranging System called a LIDAR (Laser Imaging Detection and Ranging) and the like may be used to acquire information on the state of each area, such as the number of workers in each

area

1, 2, 3.

Next, the space control device (the lighting device 11, the air-conditioning device 12, the fragrance device 13, the audio device 14, and the video device 15) and the control apparatus 20 will be described in detail.

[ Lighting device 11]

The illumination device 11 is a device capable of controlling at least one selected from the brightness (output), light color (color temperature), light distribution, and light panning (movement) of a space. The configuration, arrangement, and the like of the illumination device 11 are not particularly limited. As the lighting fixture 11, various fixtures such as a ceiling lamp, a line lamp, a floor lamp, a down lamp, a ceiling lamp, and a spotlight can be applied. The illumination device 11 includes, for example, semiconductor Light Emitting elements such as red, green, and blue LEDs (Light Emitting diodes), and the Light quantity of each color LED is adjusted by a control circuit, thereby controlling the output, color temperature, and the like of illumination Light. The lighting device 11 may have an optical lens, and may control the light distribution angle by changing the distance between the light source and the lens, or may have a panning function that can change the light irradiation direction.

The lighting devices 11 may be provided in the

areas

1, 2, and 3, respectively, one or more. In the case where a plurality of lighting apparatuses 11 are provided in each region, the plurality of lighting apparatuses 11 may be the same fixture or may be differently configured fixtures. In the example shown in fig. 1 and 2, the same number (3 each) of the same lighting devices 11 is provided at the ceiling of each area. In this case, the lighting environment of each area can be replaced by simply replacing the control parameters such as the output and the color temperature set for each lighting apparatus 11 of each of the

areas

1, 2, and 3 with the control parameters of the lighting apparatuses 11 of the other areas. For example, the initial set color temperatures set for each of the lighting apparatuses 11 in the

regions

1, 2, and 3 are 3000K, 4000K, and 5000K, respectively, and after 12 hours as a predetermined period has elapsed, the color temperatures set for each of the lighting apparatuses 11 in the

regions

1, 2, and 3 are replaced with 4000K, 5000K, and 3000K, respectively. At this time, since parameter variation is allowed if within the same light source color classification, the color temperatures set for each of the luminaires 11 of the

regions

1, 2, 3 may be replaced with 3900K, 4700K, 2700K, respectively, after 12 hours as a predetermined period has elapsed. The environment replacement by the lighting device is determined by the measurement result of the measurement device such as a color illuminometer and the set value of the parameter setting processing unit.

[ air-conditioning apparatus 12]

The air conditioner 12 is a device capable of controlling at least one selected from the temperature, humidity, and flow of air of a space. The air conditioner 12 is a device capable of performing operations such as cooling, heating, dehumidification, humidification, and air blowing, and capable of arbitrarily controlling an output, an air volume, an air direction, and the like. The configuration, arrangement, and the like of the air conditioner 12 are not particularly limited. The air conditioner 12 may be applied to various devices such as an air conditioner, a heater, a fan, an air cleaner, a dehumidifier, a humidifier, and a ceiling fan. The replacement of the environment by the air conditioner is determined by the measurement result of the measuring device such as a hygrothermograph or the set value of the parameter setting processing unit.

Similarly to the lighting device 11, the air-conditioning device 12 may be provided in one or more of the

areas

1, 2, and 3, and when a plurality of air-conditioning devices 12 are provided in each area, the plurality of air-conditioning devices 12 may be the same device or different devices (the same applies to the fragrance device 13, the audio device 14, and the video device 15). For example, when the

areas

1, 2, and 3 are adjacent to each other, the temperature, humidity, and the like of all the areas may be controlled to be the same by 1 air conditioner 12. In this case, the air conditioning apparatus 12 cannot be utilized in the replacement of the space environment. The same applies to other space control devices, and all the areas may be controlled to the same space environment and not used for replacing the space environment.

[ fragrance means 13]

The fragrance device 13 is a device that emits a predetermined fragrance into a space and controls the fragrance in the space. The fragrance device 13 has a function of arbitrarily controlling, for example, the kind of fragrance, the intensity of the fragrance, and the like. An example of the fragrance device 13 is a fragrance diffuser that can emit several kinds of fragrances. The structure of the fragrance device 13 is not particularly limited, and various structures such as a heating type, an ultrasonic type, and a blowing type can be applied as the fragrance device 13. In addition, the fragrance device 13 may have a humidifying function or the like as the air conditioning device 12. The environmental replacement by the fragrance instrument is determined by the measurement result of the measurement instrument such as the odor detection sensor and the set value of the parameter setting processing unit.

[ Acoustic apparatus 14]

The acoustic device 14 is a device that emits sound to a space and controls the sound of the space. The acoustic apparatus 14 has a function of arbitrarily controlling, for example, music content, volume (output), tone quality, and the like. Examples of the acoustic device 14 include a speaker, an earphone, a headphone, and the like. The structure of the acoustic equipment 14 is not particularly limited, and various structures such as a dipole type, a bass reflex type, and a passive radiation type (drone) can be applied to the acoustic equipment 14. The audio device 14 has a memory for storing music content, a function for receiving music content, an equalizer function, and the like. The audio equipment 14 may be integrated with other space control equipment such as the lighting equipment 11 and the video equipment 15. The environmental replacement by the acoustic equipment is determined by the measurement result of the measurement equipment such as a noise meter and a spectrum analyzer, the parameter of each music given to the music distribution site, and the set value of the parameter setting processing section.

[ image device 15]

The video device 15 is a device that controls video output to a space. The imaging device 15 has a function of arbitrarily controlling, for example, image content, brightness, color, projection range, projection position, and the like. An example of the video device 15 is a device including a display, a projector, and the like, and may be a general television. The video device 15 has a memory for storing video contents or has a function of receiving video contents. The video equipment 15 may be applied to various devices, and may be integrated with other space control equipment such as the lighting equipment 11 and the audio equipment 14. The environment replacement by the video device is determined by the measurement result of the measurement device such as a color illuminometer and the set value of the parameter setting processing unit.

[ control device 20]

As described above, the control device 20 is configured to: different control parameters are set for each of the spatial control devices in each of the

regions

1, 2, and 3 to control the spatial control devices, and the region to which the set control parameters of the spatial control devices are applied is changed at predetermined intervals. The control device 20 includes a parameter setting processing unit 23 and an application area change processing unit 24 as processing units for executing the functions. The control device 20 may further include a region area change processing unit 25, and the region area change processing unit 25 may change the area of at least one of the

regions

1, 2, and 3 by expanding or contracting the application range of the set control parameter of the space control equipment.

The control device 20 is configured by a computer including a processor 21, a memory 22, an input/output interface, and the like. The processor 21 is configured by, for example, a CPU or a GPU, and reads and executes application software (control program) for executing the functions of the space control system 10 to realize the functions of the processing units. The memory 22 includes a nonvolatile memory such as a ROM, HDD, SSD, or the like, and a volatile memory such as a RAM, which stores the control program, the control parameter of the space control apparatus, the predetermined period of the replacement control parameter, or the like.

The control device 20 is configured by a server that can access the space control devices to be controlled in the

areas

1, 2, and 3 via a wide area network such as the internet or a private network such as an intranet. The server may be a dedicated server of the space control system 10, or may also serve as an arithmetic device of another system. By installing a control program for executing the functions of the space control system 10 in the server, the server can be caused to function as the control device 20. The control device 20 may be configured by a server, a cloud server, a general personal computer, a tablet terminal, or the like provided in the office 100.

The parameter setting processing unit 23 has a function of setting a control parameter for each of the spatial control devices in each of the

areas

1, 2, and 3. In the examples shown in fig. 1 and 2, it is assumed that different control parameters are set in the lighting devices 11 in the area 1, the lighting devices 11 in the area 2, and the lighting devices 11 in the area 3, and the lighting environments in the respective areas are made different. The parameter setting processing unit 23 sets the same control parameters for the same lighting devices 11 in each area. In other words, the parameter setting processing unit 23 creates a group of the lighting apparatuses 11 having the same control parameter.

The parameter setting processing unit 23 sets control parameters such as output and color temperature for each lighting apparatus 11 based on a predetermined setting operation, and stores the set control parameters in the memory 22. The predetermined setting operation is performed by a system administrator or a user (staff) using, for example, a dedicated controller or a tablet terminal, a smart phone, a personal computer, or the like, in which application software of the space control system 10 is installed. The control device 20 transmits the set control parameter to the lighting apparatus 11, and the lighting apparatus 11 is turned on in accordance with the parameter. The control device 20 has positional information of each lighting apparatus 11, and is configured to be able to acquire information on the lighting state of each lighting apparatus 11.

Table 1 shows an example of the control parameters of each space control apparatus set by the parameter setting processing unit 23.

[ Table 1]

As described above, the parameter setting processing unit 23 sets the same control parameter for a plurality of space control devices of the same type to create a group of space control devices. The parameter setting processing section 23 creates, for example, a first group in which the output and color temperature are set as a first condition, a second group in which the output and color temperature are set as a second condition, and a third group in which the output and color temperature are set as a third condition. Since the first to third conditions are different from each other, a plurality of

regions

1, 2, and 3 having different illumination environments can be formed. The areas of the

regions

1, 2, and 3 may be changed according to the number of spatial control devices (the number of spatial control devices constituting a group) to which the same control parameter is set.

The application area change processing unit 24 has the following functions: at predetermined intervals, the control parameter of the space control device of one of the plurality of areas is replaced with the control parameter of the same type of space control device of the other area, and the space environments of the plurality of areas are replaced. The application area change processing unit 24 replaces the control parameters of the space control equipment that has been initially set or changed in setting with the control parameters of the same type of space control equipment in another area, for example, by using the function of the parameter setting processing unit 23, and stores the newly set control parameters in the memory 22. Thereafter, the replacement of the control parameter is repeatedly performed every time a predetermined period elapses.

In the examples shown in fig. 1 and 2, at a point in time when the predetermined period has elapsed, the control parameter B1 of the lighting apparatus 11 of the area 1 is applied to the lighting apparatus 11 of the area 2, the control parameter B2 of the lighting apparatus 11 of the area 2 is applied to the lighting apparatus 11 of the area 3, and the control parameter B3 of the lighting apparatus 11 of the area 3 is applied to the lighting apparatus 11 of the area 1, respectively. Here, the control parameters B1, B2, and B3 represent control parameters before a predetermined period in each of the

areas

1, 2, and 3 elapses. Since the lighting fixtures 11 in each area are the same fixture, the application area change processing unit 24 simply replaces the same fixtures without changing control parameters, for example.

In other words, the application area change processing unit 24 changes the control parameters between the groups of the lighting fixtures 11, which are initially set to the same control parameters, every predetermined period. Specifically, the initial control parameters of the first group are newly set as the control parameters of the second group. Further, the initial control parameters of the second group are newly set as the control parameters of the third group, and the initial control parameters of the third group are newly set as the control parameters of the first group.

In the case where the number of the lighting fixtures 11 constituting each group is different in the initial setting, the application region change processing unit 24 may replace the control parameter so as to increase or decrease the number of the lighting fixtures 11 constituting each group and thereby prevent the areas of the

regions

1, 2, and 3 from varying. Alternatively, the control parameters may be replaced so that the number of the lighting fixtures 11 to which the control parameters that have been initially set are applied does not vary. In the latter case, the areas of the

regions

1, 2, and 3 vary.

When two or more types of space control devices are provided in each of the plurality of areas, the application area change processing unit 24 replaces the control parameter of at least one type of space control device with the control parameter of the same type of space control device in the other area every predetermined period. For example, in the case where the lighting fixture 11, the fragrance device 13, and the acoustic device 14 are provided in each of the areas 1, 2, and 3 (see fig. 4 described later), only the control parameters of the lighting fixture 11 may be replaced between the areas. Alternatively, the control parameters of all the spatial control devices including the fragrance device 13 and the sound device 14 may be replaced.

The predetermined period may be set to any period such as half a day, 1 week, 2 weeks, 1 month, and the like, but is preferably set to 1 year or less. The business activities are planned on a per-year basis, and the arrangement of the staff in the business unit and organization changes on a per-year basis in many cases. By setting the predetermined period to 1 year, it is possible to activate communication of the employee in the organization immediately after the department call. Similarly, in many cases, the business activities advance in two divisions of the first year and the second year or in four divisions of the first quarter to the fourth quarter within 1 year, and accordingly, the arrangement of the staff in the business unit or organization changes every 6 months or 3 months in many cases. By setting the predetermined period to 6 months or 3 months, the communication of the employee in the organization immediately after the department call can be activated. Further, regardless of whether there is a local call, by finely replacing the call with a short predetermined period such as half a day or 1 day, staff who are communicating on a daily basis are changed, and intra-organization communication is activated. The application area change processing unit 24 may replace the control parameters of the space control devices a plurality of times a day, for example, in the morning and afternoon. In addition, even if the predetermined period does not elapse, the control parameters of the space control apparatus may be replaced at any time by an employee, a manager such as a general service, or the like. When different types of space control devices such as the lighting devices 11 and the air-conditioning devices 12 are installed in each area, the application area change processing unit 24 may replace the control parameters for all the space control devices at the same time, but may set different predetermined periods for each type of space control device.

The application area change processing unit 24 may include, for example, a part thereof, a process of randomly replacing the control parameters of the space control device at predetermined intervals. Alternatively, the replacement of the control parameters at predetermined intervals may be performed regularly as in the region 1 → the region 2 → the region 3 → the region 1 \8230. In this case, since the employee can predict the alternative mode of the spatial environment, the region to be used can be considered in advance. On the other hand, it is expected that, when the control parameter is replaced at random for each predetermined period, since the replacement pattern of the spatial environment cannot be predicted, the employee selects the area to be used in accordance with the mood, intuition, or the like of the day, and there is a possibility that the change of the person who wants to communicate is further promoted.

The area change processing unit 25 has a function of changing the area of at least one of the plurality of

areas

1, 2, and 3 by increasing or decreasing the number of spatial control devices in which the same control parameter is set. When the area of the region can be changed by changing the range (the number of spatial control devices) to which the same control parameter is applied, the region area change processing unit 25 can reduce the area of the region by, for example, narrowing the range to which the same control parameter is applied. On the other hand, the area of the region can be increased by expanding the range to which the same control parameter is applied outside the region. In addition, when the

areas

1, 2, and 3 are adjacent to each other, if the area of one area is changed, the areas of the other areas are also changed in general.

The change of the area of the region by the region area change processing unit 25 may be performed at any timing, or may be performed in accordance with the timing of replacing the space environment. The area change processing unit 25 measures the number of workers per area from sensor information such as an image of the camera 30, for example, and changes the area of each area based on the measured value. Specifically, the area of the region in which the number of people is less than the predetermined threshold is reduced, and the area of the region in which the number of people is more than the predetermined threshold is increased. In addition, in the case where the

areas

1, 2, and 3 are adjacent to each other, for example, when the number of workers in one area exceeds a threshold value and the number of workers in the other area is lower than the threshold value, the area of the one area is enlarged and the area of the other area is reduced.

According to the space control system 10 having the above configuration, it is possible to activate communication between employees by promoting movement of employees between areas while keeping a certain number of employees who always use a specific area.

In the example shown in fig. 1 and 2, the illumination environment of each area is replaced at regular intervals such as every 1 day, 1 week, etc. in the office 100 divided into the plurality of

areas

1, 2, 3, whereby it is possible to suppress the employees from remaining in the same area. In particular, an employee having high environmental preference (lighting preference) moves to another area as the lighting environment changes. For example, it is expected that employee a who likes the lighting environment of initial area 1 moves to area 2 in which the lighting environment of initial area 1 is reproduced after a predetermined period of time has elapsed. For the same reason, employees D and E having high preference in illumination move to other areas. In the example shown in fig. 1 and 2, employee E moves from area 2 to area 3 and employee D moves from area 3 to area 1.

On the other hand, it is expected that employees having high place preference, such as employee B who likes the copying machine 5 (e.g., high frequency of use of the copying machine 5), employee F who likes the bookshelf 6 (e.g., high frequency of use of the bookshelf 6), and employee C who likes the vending machine 7 (e.g., high frequency of use of the vending machine 7), will not move from the original area even if the lighting environment changes. That is, since there are employees who move to other areas due to environmental preference and employees who do not move due to location preference, the person who wants to communicate changes, and communication between the employees can be activated.

Fig. 4 is a diagram showing a modification of the above embodiment. The space control system 10 illustrated in fig. 4 includes

lighting fixtures

11A, 11B, and 11C having different structures in the

areas

1, 2, and 3, respectively. In this case, the lighting environments in the

areas

1, 2, and 3 may be replaced by simply replacing the control parameters of the

lighting fixtures

11A, 11B, and 11C with the control parameters of other lighting fixtures in other areas at predetermined intervals. However, since the

lighting fixtures

11A, 11B, and 11C have different structures, the target lighting environment may not be achieved simply by replacing the control parameters. Therefore, the control device 20 may correct the set values of the control parameters of the

lighting fixtures

11A, 11B, and 11C so that the initial lighting environment of each area can be reproduced in the other areas. For example, the corrected control parameters of the lighting fixture 11A are newly set as the control parameters of the lighting fixture 11B.

In the example shown in fig. 4, a fragrance device 13 and an audio device 14 are provided in each of the

areas

1, 2, and 3. The control device 20 may fix the control parameters of the

lighting fixtures

11A, 11B, and 11C to the initial set values themselves, and replace the control parameters of at least one of the fragrance equipment 13 and the audio equipment 14 with the control parameters of the same type of equipment in the other region. In this case, the lighting environment of each region does not change automatically every predetermined period, but the spatial environment can be replaced by the change of the fragrance and music of each region.

In the example shown in fig. 4, there are small windows 8 in zone 1, large windows 9 in zone 2, and no windows in zone 3. The presence and size of the window can be an important factor in the area of the employee to choose for use. Further, although the window cannot control the brightness arbitrarily as in the case of a lighting fixture, the window also affects the spatial environment. Therefore, similarly to the example shown in fig. 1 and 2, there are a certain number of employees who remain in the original area even if the space environment of each area is replaced, and communication with employees who move to other areas due to changes in the space environment is realized.

Fig. 5 is a flowchart showing an example of a basic control procedure of the space control system 10 having the above-described configuration. As illustrated in fig. 5, in the control process of the space control system 10, first, control parameters are set for each space control apparatus of each area (S10). In other words, a group of air control devices operating with the same control parameters is created. The process of S10 is executed by the function of the parameter setting processing section 23. The set control parameters are transmitted to the space control devices, and the space control devices operate in accordance with the parameters to realize a predetermined space environment in each area (S11).

Then, at a time point when the predetermined period has elapsed (S12), the control parameters of the space control apparatus are replaced to replace the space environment of each area (S13). This process is executed by the function of the application area change processing unit 24. As described above, the application area change processing unit 24 replaces the spatial environments of the plurality of areas by replacing the control parameter of the spatial control device of one of the plurality of areas with the control parameter of the spatial control device of the same kind of the other area. In this case, the control parameter may be simply replaced without changing it, or the control parameter may be corrected and the corrected parameter may be applied to the device in another area.

In the above embodiment, the lighting apparatus 11 is mainly exemplified as the space control apparatus, but another space control apparatus such as the air conditioner 12 may be used for controlling the space environment instead of the above-described lighting apparatus 11 or in addition to the lighting apparatus 11.
