(Embodiment)
[Constitution]
First, the configuration of the environmental control system according to the embodiment will be described. FIG. 1A is a plan view showing an outline of an office in which the environmental control system according to the embodiment is used and before the light emission control is changed. FIG. 1B is a plan view showing an outline of an office in which the environmental control system according to the embodiment is used and the light emission control is changed. FIG. 2 is a block diagram showing a functional configuration of the environmental control system according to the embodiment.

The environmental control system 100 according to the embodiment is used in an environment such as an office where a work place can be freely selected according to the work to be performed by oneself, and is a system for controlling such an environment. In the embodiment, it is assumed that the environmental control system 100 is used in an ABW (Activity Based Working) type office. Here, "ABW" refers to a work style in which a user (employee, etc.) selects a place or desk, etc. to work according to the work content. In an ABW-type office, the user can select a relatively quiet place for work that requires concentration, and a relaxing place such as a sofa for meetings. Is.

The environmental control system 100 may be used not only in an ABW type office but also in a free address type office, as long as the environment allows the user to freely select a work place according to the work desired to be performed. It may be used in other environments. For example, the environmental control system 100 may be used in an educational facility such as an elementary school, a junior high school, a high school, or a university, may be used in a public facility such as a public hall or a library, or may be used in a store or a commercial facility. May be done.

As shown in FIG. 2, the environment control system 100 includes a lighting control unit 11, an instruction unit 12, an acquisition unit 13, a calculation unit 14, a setting unit 15, and a storage unit 16. The environmental control system 100 may include at least an instruction unit 12, an acquisition unit 13, and a calculation unit 14, and may not include a lighting control unit 11, a setting unit 15, and a storage unit 16. For example, when a lighting control system different from the environment control system 100 exists, this lighting control system can function as the lighting control unit 11.

Further, in the environment where the environmental control system 100 is used (here, the ABW type office 3), as shown in FIGS. 1A and 1B, a plurality of lighting fixtures 1 are installed. The environmental control system 100 may be installed in the office 3 or may be installed in a remote place away from the office 3.

Each lighting fixture 1 is installed on the ceiling of the office 3. Of course, each luminaire 1 may be installed not only on the ceiling of the office 3 but also on the wall, floor, or desk. In the embodiment, each luminaire 1 is, for example, a base light as ambient lighting that uniformly illuminates a target space, and includes a light source having a solid-state light emitting element such as an LED (Light Emitting Diode). .. Further, the light source of each lighting fixture 1 is configured to be capable of dimming, toning, or both by being controlled by the lighting control unit 11.

Each luminaire 1 is assigned to a plurality of groups G1. In the example shown in FIG. 2, each luminaire 1 is assigned to three groups G1. Of course, the number of the group G1 is not limited to three, and may be two or four or more. Here, one or more luminaires 1 assigned to the same group G1 are located close to each other. Then, one or more lighting fixtures 1 assigned to a certain group G1 illuminate the space corresponding to the group G1 in the office 3.

For example, assume that the three groups G1 are the groups "A", "B", and "C". In this case, one or more luminaires 1 assigned to the group "A" illuminate the space "α" corresponding to the group "A" in the office 3, and one or more luminaires 1 assigned to the group "B". Illuminates the space "β" corresponding to the group "B" in the office 3, and one or more luminaires 1 assigned to the group "C" provide the space "γ" corresponding to the group "C" in the office 3. Illuminate.

In this way, one or more luminaires 1 assigned to the group G1 illuminate the space corresponding to the group G1. That is, in the embodiment, the lighting control unit 11 controls the light emission of the lighting fixture 1 assigned to each of the plurality of (here, three) spaces. Here, the plurality of spaces include at least one specific space SP1 (see FIGS. 1A and 1B). The specific space SP1 is a space in which the lighting fixture 1 is controlled to emit light based on the residence index described later. In the embodiment, the plurality of spaces are all the specific space SP1. That is, it can be said that the lighting control unit 11 controls the light emission of the lighting fixture 1 assigned to each of the plurality of specific spaces SP1.

The assignment of each luminaire 1 to the group G1 is executed in advance by, for example, the administrator of the environmental control system 100. The administrator executes the above allocation by using, for example, an information terminal capable of setting the parameters of the environmental control system 100. The information terminal may include, for example, a smartphone, a tablet terminal, a personal computer, or the like.

In the office 3, the adjacent spaces may or may not be partitioned. In an embodiment, it is assumed that the office 3 consists of one large room and there are no other rooms separated by walls or fixtures. In this case, the outlook of the office 3 is improved and the design is improved, which is preferable.

Further, in the embodiment, in two adjacent spaces, the light emitted from the lighting fixture 1 installed in one space does not have to illuminate exactly one space, and a part of the light may be emitted. It is allowed to leak into the other space. That is, in any space, the light emitted from the luminaire 1 corresponding to the space may be the main illumination light, and even if a part of the illumination light from a space different from the space leaks out. , It suffices to have little effect on the lighting of the space. This is because, at this time, the influence of a part of the illumination light from the space different from the space on the visibility of the user who uses the space or the work environment seen by the user is limited.

The lighting control unit 11 can communicate with each lighting fixture 1, and controls dimming, toning, or both of each lighting fixture 1 by transmitting a lighting control signal to each lighting fixture 1. In the embodiment, the lighting control unit 11 transmits the same lighting control signal to one or more lighting fixtures 1 assigned to the same group G1. That is, the lighting control unit 11 controls each lighting fixture 1 for each group G1. The communication between the lighting control unit 11 and each lighting fixture 1 may be wired communication, wireless communication, and the communication standard is not particularly limited. Further, the lighting control signals do not have to be transmitted exactly at the same time, and the time difference between the transmission of the plurality of lighting control signals is preferably within 60 minutes, more preferably within 30 minutes, and further preferably within 1 minute. If the time difference is within 60 minutes, it saves labor as compared with manually moving furniture or furniture to change the environment of the space, which is preferable.

Further, the lighting control signals transmitted from the lighting control unit 11 to one or more lighting fixtures 1 assigned to the same group G1 do not have to be exactly the same, and the influence of the space is limited. It is permissible that there is an error in the control content. For example, the permissible range is ± 500K for the color temperature and ± 20% for the dimming rate.

The instruction unit 12 gives an instruction to the lighting control unit 11 by transmitting a control signal to the lighting control unit 11. When the lighting control unit 11 receives the control signal from the instruction unit 12, the lighting control unit 11 uses one or more lighting fixtures 1 of each group G1, in other words, one or more lighting fixtures 1 assigned to each space, according to the content of the received control signal. Control.

The acquisition unit 13 acquires information about users existing in each of the plurality of specific spaces SP1. The acquisition unit 13 acquires the user's existence information or the user's identification information. When the calculation unit 14 calculates the retention index according to the [first calculation example] of the [retention index calculation] described later, the acquisition unit 13 may be in a mode in which the user's existence information can be acquired. On the other hand, when the calculation unit 14 calculates the retention index according to the [second calculation example] of the [retention index calculation] described later, the acquisition unit 13 may be in a mode in which the user's identification information can be acquired.

The acquisition unit 13 can acquire the user's existence information by acquiring the detection result transmitted from the human sensor such as the infrared sensor installed in the specific space SP1 of the office 3, for example. That is, by acquiring the detection result of the motion sensor, the acquisition unit 13 can acquire information regarding the existence or nonexistence of the user in the specific space SP1, that is, the existence information of the user.

Further, the acquisition unit 13 acquires the detection result from the indoor position information detection system using BLE (Bluetooth (registered trademark) Low Energy) or the like adopted in the office 3, for example, to obtain the user's existence information or the user. It is possible to acquire the identification information of.

Further, the acquisition unit 13 acquires an image of the office 3 taken from a camera installed in the office 3, for example, and executes an appropriate image analysis process on the image to identify the user's existence information or the user. It is possible to get information.

In addition, the acquisition unit 13 can acquire the user's existence information or the user's identification information by acquiring the reading result of the wireless IC tag possessed by the user from, for example, the tag reader installed in the specific space SP1. be.

The calculation unit 14 calculates the retention index of the user in each of the plurality of specific space SP1s based on the information about the user acquired by the acquisition unit 13. Here, the "retention index" is an index for evaluating the specific space SP1 and is an index having a correlation with a change in the number or configuration of users existing in the specific space SP1 with respect to the passage of time. For example, the residence index decreases as the frequency of changes in the number of users existing in the specific space SP1 in a unit time (tens of minutes, hours, etc.) increases, and increases as the frequency decreases. Further, for example, the residence index decreases as the frequency of changes in the configuration of the user existing in the specific space SP1 in a unit time increases, and increases as the frequency decreases. The retention index is calculated based on time information and at least one of the number of users and identification information. The calculation method of the retention index will be described in detail in [Calculation of retention index] described later.

In the specific space SP1 having a large retention index, there is a high possibility that the number or configuration of users existing in the specific space SP1 hardly changes over time. On the other hand, in the specific space SP1 having a small retention index, there is a high possibility that the number or configuration of users existing in the specific space SP1 will change over time. Therefore, in the specific space SP1 having a small retention index, it can be expected to improve the probability of occurrence of accidental communication, which is expected in, for example, an ABW type office or a free address type office. And since the possibility of innovation being created by various communication is increased, it is preferable for the manager who operates the office.

When the residence index calculated by the calculation unit 14 exceeds the threshold value, the instruction unit 12 instructs the lighting control unit 11 to change the light emission control of the lighting fixture 1 in the specific space SP1. In embodiments, the retention index is a positive real number with a maximum value of "1". The threshold value is, for example, a value of 0.5 or more, and may be set in advance by, for example, the manager or the builder of the environmental control system 100. Further, the threshold value may be appropriately set by the setting unit 15 described later.

As already described, in the embodiment, there are a plurality of specific spaces SP1. Therefore, in the embodiment, when the residence index calculated by the calculation unit 14 exceeds the threshold value in the specific space SP1 of any one of the plurality of specific space SP1, the instruction unit 12 at least in the specific space SP1. The lighting control unit 11 is instructed to change the light emission control of the lighting fixture 1. That is, when the residence index exceeds the threshold value in any specific space SP1, the instruction unit 12 instructs to change the light emission control of the lighting fixture 1 in the specific space SP1. Of course, the instruction unit 12 may also instruct to change the light emission control of the lighting fixture 1 of the other specific space SP1.

The instruction unit 12 changes the light emission control of the lighting fixture 1 in the specific space SP1 so as to change the light emission control of the lighting fixture 1 in the specific space SP1 in order to make the user who exists in the specific space SP1 whose residence index exceeds the threshold value tend to stay. Instruct 11. For example, the instruction unit 12 instructs the lighting control unit 11 to change the set value of the illuminance or the color temperature of the illumination light from the lighting fixture 1 of the specific space SP1 whose residence index exceeds the threshold value, or the specific space. The lighting control unit 11 is instructed to switch the lighting fixture 1 from the base light to the spotlight.

Further, for example, the instruction unit 12 instructs the lighting control unit 11 to increase or decrease the number of the lighting fixtures 1 assigned to the specific space SP1 whose residence index exceeds the threshold value (that is, expand or contract the specific space SP1). It is possible to do. In this case, the instruction unit 12 instructs the lighting control unit 11 to increase or decrease the number of the lighting fixtures 1 assigned to the other specific space SP1 as the number of the lighting fixtures 1 assigned to the specific space SP1 increases or decreases. do. That is, the light emission control of the lighting fixture 1 is a control for changing the set value of the illuminance or the color temperature, a control for increasing or decreasing the number of the lighting fixtures 1 assigned to the specific space SP1 whose residence index exceeds the threshold value, or a spot light irradiation. May include control over. It should be noted that the control of irradiating the spot light can be executed only when the lighting fixture 1 is provided with the spotlight in addition to the base light.

In particular, in the embodiment, the instruction unit 12 changes the light emission control of the lighting fixture 1 in the specific space SP1 in order to encourage the user of the specific space SP1 whose residence index exceeds the threshold value to move to another space. The lighting control unit 11 is instructed to do so. That is, the light emission control of the luminaire 1 may include a control for urging the user to move to a space other than the specific space SP1 whose residence index exceeds the threshold value.

For example, it is assumed that the color temperature of the illumination light of the specific space SP1 is relatively low and the illumination is a warm color system before the residence index exceeds the threshold value. In this case, the instruction unit 12 instructs the illumination control unit 11 to raise the color temperature of the illumination light of the specific space SP1. As a result, the color temperature of the illumination light of the specific space SP1 becomes relatively high, resulting in cold-colored illumination. Then, it can be expected that the user who has stayed in the specific space SP1 because he / she prefers the warm color lighting is more likely to move to another space in search of the warm color lighting.

Further, for example, it is assumed that the specific space SP1 is uniformly illuminated by the base light before the residence index exceeds the threshold value. In this case, the instruction unit 12 instructs the lighting control unit 11 to switch the lighting fixture 1 of the specific space SP1 from the base light to the spotlight. As a result, the specific space SP1 is illuminated by the spot light. Then, it can be expected that the user who stayed in this specific space SP1 because he / she prefers uniform lighting is more likely to move to another space in search of uniform lighting.

Here, when the environment of the specific space SP1 whose residence index exceeds the threshold value changes as described above, the user in a space other than the specific space SP1 prefers the environment of the specific space SP1. There is a possibility of moving to the specific space SP1. That is, it can be said that the light emission control of the lighting fixture 1 may include a control for urging the user to move from a space other than the specific space SP1 whose residence index exceeds the threshold value to the specific space SP1.

For example, when the number of lighting fixtures 1 allocated in the specific space SP1 whose residence index exceeds the threshold value increases, the specific space SP1 is expanded and an empty space is created in the specific space SP1. In this case, it can be expected that a user who has stayed in another space is more likely to move to the specific space SP1 in order to use the empty space of the specific space SP1.

Hereinafter, specific examples of instructions for changing the light emission control of the lighting fixture 1 in the specific space SP1 by the instruction unit 12 will be described with reference to FIGS. 1A and 1B. In the following, in FIGS. 1A and 1B, the specific space SP1 at the lower left of the office 3 is the "first space SP11", the space at the upper right of the office 3 is the "second space SP12", and the space at the lower right of the office 3. Will be described as "third space SP13".

In the example shown in FIG. 1A, in the first space SP11, each luminaire 1 has a warm color system in which the color temperature of the illumination light is lower than the reference color temperature (here, 5000K) (here, 3000K). Is controlled. Further, in the example shown in FIG. 1A, in the second space SP12, each luminaire 1 is controlled so that the color temperature of the illumination light is higher than the reference color temperature (here, 6000 K) and the illumination is a cold color system. There is. Further, in the example shown in FIG. 1A, in the third space SP13, each luminaire 1 is controlled so that the color temperature of the illumination light becomes the reference color temperature.

Here, it is assumed that the residence index exceeds the threshold value in the first space SP11. Then, as shown in FIG. 1B, the instruction unit 12 instructs the illumination control unit 11 so that the color temperature of the illumination light of the first space SP11 is higher than the reference color temperature (here, 6000K). At this time, the instruction unit 12 instructs the second space SP12 and the third space SP13 whose residence index does not exceed the threshold value to change the light emission control. Specifically, as shown in FIG. 1B, the indicator 12 sets the color temperature of the illumination light of the third space SP13 as the reference color temperature so that the color temperature of the illumination light of the second space SP12 becomes the reference color temperature. The lighting control unit 11 is instructed to be lower than (here, 3000K).

As a result, it can be expected that the user staying in the first space SP11 is more likely to move from the first space SP11, which has the lighting environment opposite to that before the change of the light emission control. Further, since the second space SP12 and the third space SP13 after the change of the light emission control are close to the lighting environment of the first space SP11 before the change of the light emission control, the user moves to any of these spaces SP12 and SP13. It can be expected that the possibility of doing so will increase.

The setting unit 15 sets the threshold value used by the calculation unit 14 in response to the input from the user. The user can input for setting the threshold value by using, for example, the information terminal used by the user. The threshold value input by the information terminal is transmitted from the information terminal to the environmental control system 100. Then, the setting unit 15 updates the threshold value received from the information terminal as the threshold value used by the calculation unit 14. This makes it possible to reflect the user's subjectivity in determining whether or not the user is staying in the specific space SP1.

It is preferable that the threshold value setting in the setting unit 15 can be executed only by an authorized user among the users. The authority in this case is preferably given to, for example, the administrator of the environmental control system 100. Further, as already described, the threshold value may be set in advance by, for example, the manager or the builder of the environmental control system 100. In this case, the setting unit 15 is unnecessary.

The storage unit 16 is a storage device that stores information (computer program, etc.) necessary for the lighting control unit 11, the instruction unit 12, the calculation unit 14, and the like to perform operations. The storage unit 16 is realized by, for example, an HDD (Hard Disk Drive), but may be realized by a semiconductor memory, and a known electronic information storage means can be used without particular limitation.

The lighting control unit 11, the instruction unit 12, the acquisition unit 13, the calculation unit 14, the setting unit 15, and the storage unit 16 may all be mounted on the same board or housed in the same housing. .. The board or housing may be attached to furniture / furniture such as the ceiling, wall, floor, or desk of the office 3. In this case, it is preferable because the environmental control system 100 is miniaturized.

[Calculation of retention index]
Hereinafter, examples of calculation of the retention index by the calculation unit 14 are listed.

[Example of first operation]
In the first calculation example, the residence index is calculated based on the number of users existing in the specific space SP1 at an arbitrary time. The number of users can be calculated based on the user existence information acquired by the acquisition unit 13.

Specifically, the acquisition unit 13 periodically acquires the user's existence information. As a result, the acquisition unit 13 periodically acquires data associated with the time and the number of users existing in the specific space SP1 at that time. That is, the acquisition unit 13 acquires the user's existence information at an arbitrary time in each specific space SP1 as information about the user. Then, the calculation unit 14 calculates the retention index based on the data acquired by the acquisition unit 13. That is, the calculation unit 14 calculates the retention index of the user in each of the plurality of specific space SP1s based on the existence information acquired by the acquisition unit 13.

An example of calculation of the residence index in any two specific spaces SP1 will be described with reference to Table 1 below. Hereinafter, one specific space SP1 of the two specific spaces SP1 is referred to as a “first specific space”, and the other specific space SP1 is referred to as a “second specific space”. The "first calculated value" in Table 1 represents the amount of change in the number of users in the specific space SP1 with the passage of time. Here, the "first calculated value" is the number of users in the specific space SP1 at an arbitrary time acquired by the acquisition unit 13 and the specific space SP1 at the time immediately before the time acquired by the acquisition unit 13. It is the absolute value of the difference between the number of users and the number of users.

For example, the first calculated value in the first specific space at 10:00 is the number of users in the first specific space "9" at 10:00 and the number of users in the first specific space at 9:00 ". The absolute value of the difference between "10" and "1" is set. Further, for example, the first calculated value in the second specific space at 12:00 is the number of users "6" in the second specific space at 12:00 and the number of users in the second specific space at 11:00. The absolute value of the difference between the number of people "2" and the number of people is "4".

The calculation unit 14 calculates the retention index at predetermined time intervals. Here, the predetermined time is 3 hours, and in the example shown in Table 1, it is 9:00 to 12:00. First, the calculation unit 14 obtains the second calculation value at a predetermined time by calculating the sum of the first calculation values at each time at a predetermined time. In the example shown in Table 1, the second calculated value in the first specific space from 9:00 to 12:00 is "1 + 1 + 1 = 3" which is the sum of the first calculated values in the first specific space. Further, in the example shown in Table 1, the second calculated value in the second specific space from 9:00 to 12:00 is "6 + 8 + 4 = 18" which is the sum of the first calculated values in the second specific space. ..

Then, the calculation unit 14 obtains the residence index at a predetermined time by calculating the reciprocal of the second calculation value at the predetermined time. In the example shown in Table 1, since the second calculated value in the first specific space from 9:00 to 12:00 is "3", the residence index in the first specific space from 9:00 to 12:00 is , "1/3 ≈ 0.33". Further, in the example shown in Table 1, since the second calculated value in the second specific space from 9:00 to 12:00 is "18", the residence in the second specific space from 9:00 to 12:00. The index is "1/18 ≈ 0.06".

When the second calculated value is "0", the retention index divides "1" by "0", but in the embodiment, the retention index in this case is "infinity". And.

Here, the larger the residence index is, the more likely the user is to stay in the specific space SP1, and the smaller the residence index is, the more the user is not staying in the specific space SP1. Therefore, in the example shown in Table 1, from 9:00 to 12:00, the user tends to stay in the first specific space, while the user does not stay in the second specific space. That is, in the example shown in Table 1, from 9:00 to 12:00, the second specific space has the probability of accidental communication occurring as expected in an ABW type office or a free address type office. It can be said that it is a space that can be expected to improve.

[Second operation example]
In the second calculation example, the residence index is calculated based on the identification information of the user existing in the specific space SP1 at an arbitrary time. The user identification information can be acquired by the acquisition unit 13.

Specifically, the acquisition unit 13 periodically acquires the user's identification information. As a result, the acquisition unit 13 periodically acquires data associated with the time and the identification information of the user existing in the specific space SP1 at the time. That is, the acquisition unit 13 acquires the user's identification information at an arbitrary time as the information about the user. Then, the calculation unit 14 calculates the retention index based on the data acquired by the acquisition unit 13. That is, the calculation unit 14 calculates the user's residence index in the specific space SP1 for each user based on the identification information acquired by the acquisition unit 13.

An example of calculation of the residence index in any two specific spaces SP1 (here, the first specific space and the second specific space) will be described with reference to Table 2 below. In Table 2, the "user ID" represents the user's identification information. In the example shown in Table 2, the "user ID" is represented by a three-digit number. Of course, the "user ID" may be represented by a character string such as an alphabet, or may be represented by a combination of numbers and characters.

Further, the "third calculated value" in Table 2 represents the amount of change in the user's identification information in the specific space SP1 with the passage of time. Here, the "third calculated value" is the identification information of the user in the specific space SP1 at an arbitrary time acquired by the acquisition unit 13, and the specific space SP1 at the time immediately before the time acquired by the acquisition unit 13. It is the absolute value of the number of identification information that differs from the user's identification information in.

For example, the user ID in the first specific space at 10:00 is "001", "002", "003", whereas the user ID in the first specific space at 9:00 is "001", It is "002" and "003". Therefore, since there is no difference in the user's identification information between 9:00 and 10:00, the third calculated value in the first specific space at 10:00 is "0". Further, for example, the user ID in the second specific space at 10:00 is "004", "007", and "010", whereas the user ID in the second specific space at 9:00 is "004". , "005", "006". Therefore, there is no difference in the number of users in the second specific space between 9:00 and 10:00, but since the two users are interchanged, the third operation in the second specific space at 10:00. The value is "2".

The calculation unit 14 calculates the retention index at predetermined time intervals. Here, the predetermined time is 3 hours, and in the example shown in Table 2, it is 9:00 to 12:00. First, the calculation unit 14 obtains the fourth calculation value at a predetermined time by calculating the sum of the third calculation values at each time at a predetermined time. In the example shown in Table 2, the fourth operation value in the first specific space from 9:00 to 12:00 is "0 + 0 + 1 = 1" which is the sum of the third operation values in the first specific space. Further, in the example shown in Table 2, the fourth calculated value in the second specific space from 9:00 to 12:00 is "2 + 2 + 2 = 6" which is the sum of the third calculated values in the second specific space. ..

Then, the calculation unit 14 obtains the residence index at a predetermined time by calculating the reciprocal of the fourth calculation value at the predetermined time. In the example shown in Table 2, since the fourth calculated value in the first specific space from 9:00 to 12:00 is "1", the residence index in the first specific space from 9:00 to 12:00 is , "1/1 = 1". Further, in the example shown in Table 2, since the fourth calculated value in the second specific space from 9:00 to 12:00 is "6", the retention in the second specific space from 9:00 to 12:00. The exponent is "1/6 ≈ 0.17".

When the fourth calculated value is "0", the retention index divides "1" by "0", but in the embodiment, the retention index in this case is "infinity". And.

Here, the larger the residence index is, the more likely the user is to stay in the specific space SP1, and the smaller the residence index is, the more the user is not staying in the specific space SP1. Therefore, in the example shown in Table 2, from 9:00 to 12:00, the user tends to stay in the first specific space, while the user does not stay in the second specific space. That is, in the example shown in Table 2, from 9:00 to 12:00, the second specific space has the probability of accidental communication occurring as expected in an ABW type office or a free address type office. It can be said that it is a space that can be expected to improve.

The above-mentioned method for calculating the retention index is an example, and the retention index may be calculated by another method. For example, the above-mentioned first calculation value is the number of users in the specific space SP1 at an arbitrary time acquired by the acquisition unit 13, and the number of users in the specific space SP1 at the time immediately before the time acquired by the acquisition unit 13. It may be a quotient when divided by the number of users. Further, for example, the above-mentioned second calculated value may be an integrated value of the first calculated value at a predetermined time. Further, the retention index may be calculated by combining the calculation method in the above-mentioned first calculation example and the calculation method in the second calculation example.

[motion]
Hereinafter, an example of the operation of the environmental control system 100 according to the embodiment will be described. FIG. 3 is a flowchart showing an operation example of the environmental control system 100 according to the embodiment. In the following, it is assumed that the threshold value used in the calculation unit 14 is set in advance. Further, in the following, it is assumed that the lighting control unit 11 controls the light emission of each lighting fixture 1 for each group G1. Further, in the following, the description will focus on one specific space SP1 among the plurality of specific space SP1s.

First, the acquisition unit 13 periodically acquires information about the user existing in the specific space SP1 (S1). The process S1 corresponds to the acquisition step ST2 of the environment control method. When a predetermined time (for example, 3 hours) has elapsed since the acquisition unit 13 started acquiring information (S2: Yes), the calculation unit 14 has a retention index based on the information acquired by the acquisition unit 13. Is calculated (S3). The process S3 corresponds to the calculation step ST3 of the environment control method.

Then, when the residence index calculated by the calculation unit 14 does not exceed the threshold value (S4: No), the instruction unit 12 does not execute anything in particular. That is, the light emission control of each lighting fixture 1 by the lighting control unit 11 is not changed. On the other hand, when the residence index calculated by the calculation unit 14 exceeds the threshold value (S4: Yes), the instruction unit 12 tells the lighting control unit 11 to change the light emission control of the lighting fixture 1 in the specific space SP1. Instruct (S5). The process S5 corresponds to the instruction step ST1 of the environment control method. As a result, the lighting environment of the specific space SP1 is changed. Hereinafter, the above series of processes S1 to S5 are repeated.

[advantage]
Hereinafter, the advantages of the environmental control system 100 according to the embodiment will be described. In the environmental control system 100 according to the embodiment, when the residence index of the user in the specific space SP1 of the plurality of specific spaces SP1 exceeds the threshold value, that is, the user tends to stay in the specific space SP1, the said. The lighting environment of the specific space SP1 is changed. Therefore, there is an advantage that the user staying in the specific space SP1 can be given an opportunity to move to another space, and the stagnation of the user's flow line can be easily eliminated. As a result, when a user who tends to stay in the specific space SP1 moves to another space, the probability of accidental communication occurring, which is expected in an ABW type office or a free address type office, for example, is Improvement can be expected. It is also expected that the possibility of innovation being created will increase with various communications as an opportunity.

Further, in the environmental control system 100 according to the embodiment, by changing the lighting environment of the specific space SP1 whose residence index exceeds the threshold value at least, the lighting environment of each of the plurality of specific space SP1 can be made different. A so-called zoning effect can be expected.

Here, the zoning effect means, for example, a cognitive division feeling of the space, and may include an effect that the user can easily recognize that a plurality of spaces are different spaces in appearance. In addition, the zoning effect may include an effect of facilitating a change in the user's behavior or flow line as intended by the zoning, with the recognition of the user. For example, it is assumed that an arbitrary space is zoned with the intention of creating a space in which the user can easily perform work that requires concentration. In this case, it can be said that the zoning effect is exhibited if the user who sees the space uses the space mainly for the purpose of performing work requiring concentration.

In addition, the zoning effect includes an effect that the user's subjective effect / actual feeling or physiological / psychological / biological action tends to be in accordance with the purpose of zoning when the user actually uses the zoned space. obtain. For example, it is assumed that zoning is performed on an arbitrary space with the intention of making it easy to perform work that requires concentration, and the user uses the space. In this case, if the user feels that he / she can concentrate by using the space, or if the index / data suggesting that the user has concentrated as a psychological / biological action can be obtained, the zoning effect can be obtained. It can be said that it was demonstrated.

By controlling the lighting as described above, it is possible to zone each specific space SP1 without using furniture or furniture. Therefore, it is easy to enhance the design of each specific space SP1, and it is possible to perform so-called active zoning in which the layout of the office 3 is changed instantly by lighting control such as dimming and toning. That is, when zoning is performed by the above lighting control, the change of the dimming / coloring control parameters in each specific space SP1 is completed in, for example, a few seconds. In this case, as a result, the layout of the office 3 can be changed in a few seconds. Here, if the layout of the office 3 is changed by manually moving furniture or furniture, it takes 60 minutes, several hours, or one day, and in some cases several days. From this point, the above-mentioned zoning by lighting control can exert a very remarkable effect.

With active zoning, it is possible to change the layout of office 3 in a short cycle such as hourly, daily, or monthly compared to the conventional office layout change by changing the arrangement of furniture or furniture. Is.

(Other embodiments)
Although the embodiments have been described above, the present invention is not limited to the above embodiments. Hereinafter, modifications of the embodiment will be listed. The modifications described below may be combined as appropriate.

[Modification 1 of the embodiment]
In the environmental control system 100 according to the first modification of the embodiment, a plurality of acoustic devices 2 are installed in the office 3, and the instruction unit 12 gives an instruction to the acoustic control unit 17. It is different from the environmental control system 100 according to the above. FIG. 4 is a block diagram showing a functional configuration of the environmental control system 100 according to the first modification of the embodiment. The environmental control system 100 does not have to include the acoustic control unit 17. For example, when an acoustic control system different from the environmental control system 100 exists, this acoustic control system can function as the acoustic control unit 17.

Each audio device 2 is installed on the ceiling of the office 3. Of course, each audio device 2 may be installed not only on the ceiling of the office 3 but also on the wall, floor, or desk. In the embodiment, each acoustic device 2 is an omnidirectional speaker as an example, and reproduces the content transmitted from the acoustic control unit 17. Each acoustic device 2 may be a speaker having directivity such as a parametric speaker, a speaker using ultrasonic waves, or a speaker having a horn structure in a housing. It is preferable to use a speaker having directivity because it is easy to reduce the ratio of some sounds leaking to other spaces.

Each audio device 2 is assigned to a plurality of groups G1 like each lighting fixture 1. In the examples shown in FIGS. 1A-2, each acoustic device 2 is assigned to three groups G1. Here, one or more acoustic devices 2 assigned to the same group G1 are located close to each other. Then, one or more audio devices 2 assigned to a certain group G1 output sound to the space corresponding to the group G1 in the office 3.

For example, assume that the three groups G1 are the groups "A", "B", and "C". In this case, one or more sound devices 2 assigned to the group "A" output sound to the space "α" corresponding to the group "A" in the office 3, and one or more sound devices 2 assigned to the group "B". The sound device 2 outputs sound to the space "β" corresponding to the group "B" in the office 3, and one or more sound devices 2 assigned to the group "C" correspond to the group "C" in the office 3. Sound is output to the space "γ".

The assignment of each audio device 2 to the group G1 is executed in advance by the administrator of the environmental control system 100 using the information terminal in the same manner as the assignment of each lighting fixture 1 to the group G1.

In two adjacent spaces, the sound output from the acoustic device 2 installed in one space does not have to be output to only one space, and a part of the sound leaks to the other space. Is allowed. That is, in any space, the sound output from the sound device 2 corresponding to the space may be the main sound, and even if a part of the sound from a space different from the space leaks, the sound is said to be the main sound. It should not affect the sound of the space.

The acoustic control unit 17 can communicate with each acoustic device 2, and causes each acoustic device 2 to reproduce the content by transmitting an acoustic control signal (including the content to be reproduced) to each acoustic device 2.

That is, the acoustic control unit 17 controls each acoustic device 2 for each group G1. The communication between the acoustic control unit 17 and each acoustic device 2 may be wired communication, wireless communication, and the communication standard is not particularly limited.

Further, the content may be stored in the acoustic control unit 17, may be stored in each acoustic device 2, or may be stored in the storage unit 16. The content is stored in an electronic data medium such as, for example, a WAV format or an mp3 format, but is not limited to this, and may be stored by any known storage method such as a compact disc (CD).

The instruction unit 12 gives an instruction to the acoustic control unit 17 by transmitting a control signal to the acoustic control unit 17. When the acoustic control unit 17 receives a control signal from the instruction unit 12, it receives one or more acoustic devices 2 of each group G1, in other words, one or more acoustic devices 2 assigned to each space, according to the content of the received control signal. Control. That is, the instruction unit 12 is configured to instruct the acoustic control unit 17 that controls the output of the acoustic device 2 assigned to each of the plurality of specific spaces SP1.

Then, when the residence index calculated by the calculation unit 14 exceeds the threshold value in the specific space SP1 of any of the plurality of specific space SP1, the instruction unit 12 outputs at least the sound device 2 in the specific space SP1. Instruct the acoustic control unit 17 to change the control. For example, when music or the like is not played in the specific space SP1 before the residence index exceeds the threshold value, the instruction unit 12 instructs the acoustic control unit 17 to play some music or the like in the specific space SP1. .. On the other hand, when music or the like has already been played in the specific space SP1 before the residence index exceeds the threshold value, the instruction unit 12 causes the acoustic control unit 17 to play the music or the like having the opposite property in the specific space SP1. Instruct.

Then, the notification unit 18 transmits the generated map or the like to the information terminal used by the user. As a result, the user can grasp the degree of retention of the specific space SP1 by checking the map or the like received by the information terminal.

Further, the notification unit 18 may transmit the generated map or the like to the projector installed in the office 3. In this case, the projector projects the received map or the like on the screen. As a result, the user can grasp the degree of retention of the specific space SP1 by checking the map or the like projected on the screen. The projector may project a map on the wall, ceiling, or the like of the office 3 instead of the screen.

Similarly, in the first modification of the embodiment, the acoustic device 2 is not included in the components of the environmental control system 100, but the acoustic device 2 may be included in the components of the environmental control system 100.

Further, for example, in the above embodiment, the environmental control system 100 is realized by a plurality of devices, but may be realized as a single device. For example, the environmental control system 100 may be realized as a single device corresponding to a server device. When the environmental control system 100 is realized by a plurality of devices, the components included in the environmental control system 100 may be distributed to the plurality of devices in any way.
