Description

  The present invention relates to an environment adjustment system that provides each person with the most comfortable environment possible in a space used by a large number of people, such as an office.

  For example, a building air conditioning system is an example of adjusting an environment in a specific area to an optimum environment. In such a building air-conditioning system, a method of setting a temperature that is considered to be optimal and controlling the air to be a set temperature is generally performed. However, a person's thermal sensation varies from person to person, and there is a certain proportion of people who feel uncomfortable, even at the optimal temperature.

  If there is only one person in the room, such as at home, the set temperature can be freely changed to be comfortable, but in an office building where many people work in a specific area, the set temperature can be changed unless the administrator is contacted There are many cases where this is not possible. In that case, since the change of the setting value is troublesome, there are also cases in which the setting of the setting is not changed while dissatisfied with the thermal environment, and the work efficiency is lowered.

  In some cases, the temperature can be set directly by the operator, such as in a building multi-air conditioner. However, in this case as well, the temperature is determined by the feeling of a person with strong speech, and the temperature setting that represents all the people in the room is often not performed.

  Therefore, if the temperature sense information of all the people in the room is collected and the set temperature is determined by majority vote, the ratio of people who feel comfortable is maximized. In addition, dissatisfaction with air conditioning is reduced from the consciousness that they are participating in temperature setting. From such a view, a majority decision system is implemented (see, for example, Patent Document 1).

JP 2004-3759 A

  As described above, in a space used by many people, such as an office, even if the thermal environment is uncomfortable, it is generally not possible for the occupant to directly change the temperature setting value. If you can't stand it, you will need to contact the facility manager by telephone to change the settings. As a solution different from such a direct solution, a method of changing the setting from an operator's personal computer (PC) connected to a network is conceivable (see, for example, JP-A-2004-205202).

  However, when a person who wants to change the setting performs a change operation from the PC, other operators do not necessarily desire the same change. Here, in order to hear the wishes of all operators, it is conceivable to conduct a questionnaire based on the principle of majority vote described above. This is a method in which, for example, every hour, everyone asks their PCs to answer questions by e-mail, etc., and the set values are changed by collecting the answers.

  Here, when a space used by a large number of people, such as an office, is divided into a plurality of air conditioning zones, it may be possible to set the temperature by majority vote using a remote controller for each air conditioning zone. However, at positions other than the vicinity of the center of each air-conditioning zone, the air-conditioning zone is easily affected by other air-conditioning zones in the surrounding area, and therefore, a temperature setting vote for one air-conditioning zone is not sufficient. This applies not only to a portable remote controller but also to a remote controller that uses a fixed position.

  In particular, if all operators have a wireless remote control to take a majority vote, the air-conditioned space is divided into multiple air-conditioning zones, and the air-conditioner can move freely with the remote control. It becomes unclear whether it is a majority vote for the zone. In particular, when an operator is located near the boundary between a plurality of air-conditioning zones, if the majority decision for which air-conditioning participation is determined is inappropriate, the meaning of participation in the majority decision is lost.

  An object of the present invention is to provide an environment adjustment system that provides a comfortable environment for each person in a space that is used by a large number of people, such as an office, and that can improve the fairness of the majority method.

  Since not only one air-conditioning zone but also all affected air-conditioning zones can be weighted according to distance, voting can be performed so that each terminal operator can feel the temperature more comfortable. The air conditioning can be controlled.

  Hereinafter, an environment adjustment system according to a reference embodiment will be described. The environment adjustment system according to the reference embodiment is a system that adjusts air conditioning in a specific area such as an office, and is an environment in which the air conditioner is adjusted to a temperature that many people working in the area feel as comfortable as possible. It is an adjustment system.

FIG. 3 is an explanatory diagram for explaining a control method in the environment adjustment system shown in FIG. FIG. 4 is a flowchart for explaining a control method of the environment adjustment system shown in FIG.

  As shown in FIG. 1, the environmental adjustment system according to a reference embodiment is a fixed terminal 100 (100-1, 100-2, 100-3,...) Installed on each person's desk or chair. And a control device 150 that obtains information from each fixed terminal 100 and controls the air conditioner 162 so that each person in the office feels comfortable, and an air conditioner 160 controlled by the control device 150. .

  A fixed terminal 100 installed on each person's desk or chair includes a control unit 101, a temperature setting switch 102, a terminal number setting device (terminal setting switch) 104, a human detection sensor (human sensor) 105, and a wireless device. A transmission unit 106 and an antenna 107 are provided.

  On the other hand, the control device 150 includes a control calculation unit 151, a wireless transmission / reception unit 152, and an antenna 153. The air conditioner 160 includes an air conditioning control unit 161 and an air conditioner 162. The air conditioner 160 includes a temperature sensor 163.

  FIG. 2 is a perspective view schematically showing the fixed terminal 100 provided on each desk or chair. As shown in the figure, the fixed terminal 100 is composed of a small casing and a switch, an electronic device, and the like, and a human sensor 105 that detects the presence or absence of the terminal operator faces the terminal operator. In addition, a terminal setting switch 104 for specifying the terminal of each terminal operator is provided. Two voting switches (temperature setting switches) 102 are provided near the terminal setting switch 104.

  Each voting switch 102 is of a push button type, and one voting switch 102U is composed of an upward triangular push button, and a terminal operator who is present (hereinafter referred to as “present person”) surrounds herself. This is a temperature rise voting switch for conveying desired information that the user wants to raise the temperature when it feels slightly cold. Also, the other voting switch 102D is formed of a downward triangular push button, and a declining vote for clearly indicating that the occupant wants to lower the temperature when he feels that the temperature around him is slightly hot. Switch.

  In addition, a display lamp (operation reception display) 103 indicating both a voting reception start state button and a voting reception completion state button is provided at the end of the terminal. When the voting acceptance start state is reached, for example, a green LED lamp is lit, and this indicator lamp 103 informs the occupant that any voting switch can be pressed. The LED lamp is lit to notify the occupant that the vote has been accepted, so that the occupant can immediately recognize the current terminal operation status.

  The control device 150 obtains information from each fixed terminal 100 via the antenna 153 and the wireless transmission / reception unit 152, and controls the air conditioner 162 to a temperature at which each occupant feels as comfortable as possible based on the information. As described above, the calculation result is sent to the air conditioning controller 161 of the air conditioner 160.

  According to the environmental adjustment system according to the present embodiment, which is a reference, as shown in FIG. 3, the air conditioning administrator sets the set value of the air conditioner 160 and performs control calculation based on the set value to adjust the thermal environment via the heat source. This is fed back via the temperature sensor, and each attendee votes via the respective voting switch according to the degree of comfort at the room temperature felt by each person. In the present embodiment, these are added together to calculate an average value, and the result is fed back.

  The control calculation unit 151 is provided with a terminal timer B in addition to the control calculation unit timer A. In the present embodiment, the communication between each fixed terminal 100 and the control calculation unit 151 is bidirectional communication, so that the control calculation unit 151 and each fixed terminal 100 can be operated in synchronization. The timer of each fixed terminal 100 required when only direction communication, that is, only communication from each fixed terminal 100 to the control device 150 is possible is eliminated.

  Next, an environment adjustment system according to a reference embodiment will be described based on a flowchart shown in FIG.

  The control calculation unit 151 performs control according to the following routine. First, timer A is reset (step S11). Next, data from each fixed terminal 100 is received and overwritten and recorded for each terminal (step S12). Next, it is determined whether or not the timer A has elapsed a predetermined time (step S13). If it is determined in step S13 that the timer A has not elapsed, the process returns to step S12. If it is determined in step S13 that the predetermined time has elapsed, the setting change value is calculated from the received data (step S14). Next, the setting change value is output to the air conditioner 160 (step S15).

  On the other hand, each fixed terminal 100 performs control according to the following routine. First, timer B is reset (step S21). Next, the register is reset (step S22). Next, the switch state is recorded in the register (step S23). Next, it is determined whether or not the timer B has elapsed a predetermined time (step S24). If it is determined in step S24 that the timer B has not passed the predetermined time, the process returns to step S23. When it is determined in step S24 that the timer B has elapsed, it is determined whether or not the human sensor is on (step S25). If it is determined in step S25 that the human sensor is not on, the process returns to step S21. If it is determined in step S25 that the human sensor is on, the register contents are transmitted together with the terminal (step S26). Here, the length of the timer B is set to be equal to or shorter than the length of the timer A. This is to collect as much information from the fixed terminal 100 as possible while the timer A of the control calculation unit 151 is continuing.

  Hereinafter, the majority voting method according to the reference embodiment will be described more specifically. An attendee has the right to vote one vote at a predetermined time (for example, 5 minutes). The reason for limiting the time is to invalidate the repeated voting of the voting switch and perform the majority operation correctly.

  The occupant decides whether to press the voting switch 102 of the fixed terminal 100 attached to the chair or the desk, or to accept the current status as it is and press nothing. Specifically, an attendant who feels cold presses the UP button, an attendant who feels hot presses the DOWN button, and a person who desires the current situation presses nothing. When the button is pressed, information indicating that it is cold or hot, and information indicating that it is neutral if nothing is pressed are periodically transmitted from the fixed terminal 100 to the control device 150. The control calculation unit 151 of the control device 150 aggregates terminal data received within a predetermined time set by the timer A.

When the cold number is U, the hot number is D, and the neutral number is N, the set temperature change value DT is obtained as follows. DT ₀ is the temperature increment when the button is pressed once.

ここで分母のＵ＋Ｄ＋Ｎの値は在席者の総人数である。在席者のいない端末からは、人が在席していないことを人感センサ１０５が検知して電波を送信しないため、ＤＴが公平に計算される。

Here, the value of U + D + N in the denominator is the total number of attendees. Since a human sensor 105 detects that a person is not present from a terminal with no occupants and does not transmit radio waves, DT is calculated fairly.

For example, if the number of seats is 3 and U = 1, D = 0, N = 2, and DT ₀ = 0.5,

となり、設定温度を０．１７℃上昇させることになる。

Thus, the set temperature is increased by 0.17 ° C.

  In this embodiment, which is a reference, the predetermined time set in the control calculation unit 151 is longer than the air conditioning control time constant of the area adjusted by the air conditioner 160, as shown in FIG.

  When the set temperature is changed, control is performed toward the target value, and when a new setting change is performed while the air temperature is changing, a vibration state (the so-called hunting state) in which the air temperature increases or decreases. There is a possibility that wasteful air-conditioning energy may be consumed by generating (see FIG. 5A). However, in the present embodiment, the predetermined time set in the control calculation unit 151 is set to a value longer than the air conditioning control time constant of the area adjusted by the air conditioner 160 until the air temperature approaches the target temperature. Since the operation is received at a cycle longer than the air conditioning control time constant, it is possible to quickly settle (converge) the target temperature without causing a useless vibration state (see FIG. 5B). ).

  For example, in the case of FIG. 5A, since the UP button is pressed twice in succession, the air temperature rises too much, and this time, the DOWN button is pressed, and it takes time to converge to the target temperature. Although there is a drawback that the number of operations increases, in the reference embodiment, measures are taken so as not to fall into such a situation.

  As described above, in the reference embodiment, the environmental adjustment device includes the air conditioner 160, the area includes the environmental adjustment area in which the temperature in the area is adjusted by the air conditioner 160, and the fixed terminal 100 serving as a terminal operation unit. Has the following action by having a voting switch for increasing the temperature and a voting switch for decreasing the temperature.

  Specifically, the air conditioner 160 raises or lowers the temperature of a specific area within a certain period of time, that is, to the occupant who presses the voting switch that desires to change the temperature state of the surrounding environment to the voting switch. In addition, since information indicating that the current state of the ambient environmental temperature state of the person who has not pressed the voting switch is also aggregated is collected, a fair temperature setting by all the persons in attendance can be performed in a short time. In particular, the person who wants to maintain the current situation does not need any operation, and thus does not interfere with the original work.

  In addition, since the fixed terminal 100 is installed near a specific place where each occupant performs business, such as near the armrest of a chair or on a desk, it is positioned as a part of the equipment in the area. There is no need for the person to carry around. That is, each occupant does not have to carry (carry) the fixed terminal 100 in particular, so there is no inconvenience, and there is no fear of forgetting when entering or leaving the room.

  In addition, since counting is performed at regular intervals, for example, even if the same attendant pushes the switch several times in a short time, it counts only once, and the voting is fair when adjusting the temperature of the surrounding environment. Keep sex.

  In the above-described embodiment and each of the following modifications, the ambient temperature of the area to be temperature controlled is monitored by the temperature sensor 163 provided in the air conditioner 160, and the ambient temperature is close to a predetermined set temperature. In some cases, data from each fixed terminal or mobile terminal is received.

  In this manner, the ambient temperature of the area controlled by the air conditioner 160 is monitored via the temperature sensor 163, and the control device 150 accepts the operation of each fixed terminal and mobile terminal only when the temperature approaches the target temperature. This makes it possible to reliably prevent useless terminal operations during temperature changes.

  Then, the 1st modification of embodiment mentioned above is demonstrated. In addition, about the structure equivalent to embodiment mentioned above, it attaches | subjects a corresponding code | symbol and abbreviate | omits detailed description. FIG. 6 is a block diagram showing a first modification of the environment adjustment system shown in FIG. As is clear from FIG. 6, the operation reception indicator is omitted in the fixed terminal 100 as compared with the environment adjustment system according to the first embodiment shown in FIG. 1.

  In this modification, unidirectional communication is performed from the fixed terminal 100 to the air conditioner 160 via the wireless reception unit 152. Accordingly, the fixed terminal 100 includes a timer A shown in the flowchart of FIG. 4, and the air conditioner 160 includes a timer B shown in the flowchart of FIG. As described above, in the first modification, each end of the seated person is not provided with an operation reception indicator indicating both the voting reception start state and the voting reception completion state in each terminal, but this operation reception display is provided. Even if it is not, it is sufficiently possible to exhibit the function of the reference embodiment.

  However, this modification is not limited to unidirectional communication, and bidirectional communication is also applicable. In that case, the timer A of the fixed terminal becomes unnecessary. Below, the 2nd modification which has the structure as such a bidirectional | two-way communication is demonstrated. In addition, about the structure equivalent to embodiment mentioned above and its 1st modification, corresponding code | symbol is attached | subjected, and detailed description is abbreviate | omitted. FIG. 7 is a block diagram showing a second modification of the environment adjustment system shown in FIG.

  In the environment adjustment system according to the second modification, each fixed terminal 100 is provided with an operation acceptance display 103 that was not provided in the first modification. The control calculation unit 151 is provided with a terminal timer B in addition to the control calculation unit timer A. By making communication between each fixed terminal 100 and the control calculation unit 151 bidirectional communication via the wireless transmission / reception unit 152, the control calculation unit 151 and each fixed terminal 100 can be operated in synchronization. It is possible to eliminate the timer of each fixed terminal 100 required when only one-way communication, that is, only communication from each fixed terminal 100 to the control device 150 is possible.

  As a result, the operation of the operation acceptance display 103 of the reference embodiment described above can be exhibited, and the operation of the temperature sensor 163 of the first modification can be achieved.

  Then, the 3rd modification of the above-mentioned embodiment is demonstrated. In addition, about the structure equivalent to the reference embodiment mentioned above and the 1st, 2nd modification, corresponding code | symbol is attached | subjected and detailed description is abbreviate | omitted. FIG. 8 is a block diagram showing a third modification of the environment adjustment system shown in FIG.

  In the environment adjustment system according to the third modification, each fixed terminal 100 is provided with a temperature sensor 108 instead of the operation reception display 103 provided in each fixed terminal 100 in the reference embodiment. In this modification, unidirectional communication is performed from the fixed terminal 100 to the air conditioner 160 via the wireless reception unit 152. Accordingly, the fixed terminal 100 includes a timer A shown in the flowchart of FIG. 4, and the air conditioner 160 includes a timer B shown in the flowchart of FIG. However, this modification is not limited to unidirectional communication, and bidirectional communication is also applicable. In that case, the timer A of the fixed terminal becomes unnecessary.

  As described above, each fixed terminal 100 includes the temperature sensor 108, and the fixed terminal 100 that detects the presence of the occupant and the surrounding temperature sends the temperature measured via the temperature sensor 108 to the control device 150, and the control device 150. Collects the temperature data sent from each fixed terminal, calculates the average temperature data, corrects the calculation result for the air conditioning control based on the average temperature data, and performs the room temperature control via the air conditioner 160 It has become.

  The air conditioning system generally installs a temperature sensor on a pillar or the like, and performs temperature control based on the measured value. However, depending on the installation position of the temperature sensor, the temperature of the room may not necessarily be representative. Therefore, according to the environmental adjustment system according to the third modified example, the temperature sensor 108 is arranged near each occupant and the measured value is used, thereby enabling air conditioning control close to the thermal sensation of the occupant. become. In addition, a plurality of temperature sensors 108 provided in each fixed terminal and dispersed in the area can grasp the temperature of the room more accurately and perform more accurate air conditioning control.

  Subsequently, an environment adjustment system according to an embodiment of the present invention will be described. In addition, about the structure equivalent to the above-mentioned embodiment and each modification, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted.

  FIG. 9 is a block diagram illustrating an environment adjustment system according to an embodiment of the present invention. FIG. 10 is an explanatory diagram for explaining a control method of the environment adjustment system shown in FIG. FIG. 11 is an explanatory view different from FIG. 10 for explaining the control method of the environment adjustment system shown in FIG.

  The environmental adjustment system according to the embodiment of the present invention makes the work environment of a large number of people working in a closed area such as an office as comfortable as possible, as in the reference embodiment and the variations thereof. Air conditioning system for

  Note that this embodiment is different from the reference embodiment and its modifications, in which one area is divided into a plurality of zones and the air conditioners 250 (250-1, 250-2, 250-3, ...) are installed one by one, and the temperature of one area is adjusted by a plurality of air conditioners. It should be noted that the point of calculating the ideal adjustment value by majority decision by gathering opinions of many people in the area for temperature adjustment is the same as the reference embodiment and its modification.

  In the embodiment of the present invention, the environment adjustment system is a desk in which each fixed terminal 200 (200-1, 200-2, 200-3,...) Performs the operations of the operator as in the reference embodiment. It is a fixed terminal of a type installed in a specific place such as a chair or chair (see FIG. 2), and each air conditioner 250 is weighted based on information from the fixed terminal 200 of each person. Each air conditioner 256 assigned to each zone includes a control calculation unit 251 and an air conditioning control unit 255 that control each zone to have an optimum temperature.

  More specifically, each fixed terminal 200 includes a control unit 201, a terminal number setting unit 204, a temperature setting switch 202, a wireless communication unit 206, and an antenna 207. Each air conditioner 250 includes a control calculation unit 251, a wireless reception unit 252, an antenna 253, an air conditioning control unit 255, and an air conditioner 256 controlled by the air conditioning control unit 255. And each fixed terminal 200 and the control calculating part 251 of each air conditioner 250 are communicated by radio | wireless means, such as an electromagnetic wave.

  In the embodiment of the present invention, unidirectional communication is performed from the fixed terminal 100 to the air conditioner 160 via the wireless reception unit 252. Accordingly, the fixed terminal 100 includes a timer A shown in the flowchart of FIG. 4, and the air conditioner 160 includes a timer B shown in the flowchart of FIG. However, the embodiment of the present invention is not limited to unidirectional communication, and bidirectional communication is also applicable. In that case, the timer A of the fixed terminal becomes unnecessary.

  In addition, about each component of each fixed terminal 200 and each component of each air conditioner 250, since it becomes the structure equivalent to embodiment to be referred and each modification, the detailed description is abbreviate | omitted. Only the differences will be described below.

  In the embodiment of the present invention, as shown in FIG. 10, the distance (d1 to d4 in FIG. 10) from each fixed terminal 200 to the center position of the air conditioning zone controlled by each air conditioner 250 is measured. According to the distance, the weighting of the operation information of the voting switch of each fixed terminal 200 or the weighting of the information that the voting switch is not pressed is changed.

  Specifically, each fixed terminal 200 can be operated in a specific place such as under an armrest of a seated chair in the area or on a desk in the same manner as the reference embodiment and its modifications. Each fixed terminal 200 has a timer, and sends a switch state and an operator's terminal number to the control calculation unit 251 by wireless communication at regular time intervals. In addition, the control calculation unit 251 specifies the transmission position of each fixed terminal 200 from at least one of the reception intensity of mobile radio waves from each fixed terminal 200, the propagation delay time, and the arrival angle, and within a predetermined time. The information of each fixed terminal 200 sent is received and totaled. In addition, the predetermined time set in the timer of the control calculation unit 251 is set to be equal to or longer than the timer time of each fixed terminal 200, and voting is weighted according to the distance from the center of each air conditioning zone of the transmission position of the fixed terminal 200 The control calculation unit 251 performs an average calculation of data from each fixed terminal 200, calculates a setting change value, and sends the result to the air conditioning control unit 255.

  As a result, information from people who have pressed the voting switch for temperature change consisting of a temperature rising vote switch and a temperature lowering voting switch and information from those who did not press it will be aggregated within a certain time. Fair temperature setting by everyone is possible in a short time. In addition, since counting is performed at regular intervals, for example, the same occupant counts only once even if the voting switch is pressed in a short time, and keeps fairness. Further, not only one air-conditioning zone but also all affected air-conditioning zones can be voted with a weight depending on the distance.

  A specific example of this control method will be described below. FIG. 11 is an explanatory view different from FIG. 10 for explaining the control method of the environmental adjustment system shown in FIG. 9, and is a view showing the relationship between the horizontal distance and the temperature in the case of hot air blowing.

As shown in FIG. 10, it is assumed that the distances from the position of the fixed terminal 200 to the centers of the four neighboring air conditioning zones are d ₁ , d ₂ , d ₃ , and d ₄ . Assuming that air with a certain temperature energy is blowing from the center in each air-conditioning zone, as shown in FIG. 11, the energy is considered to diffuse and attenuate in proportion to the square of the horizontal distance from the outlet. Find the voting weights as follows:

ここで各空調ゾーンのエネルギー吹き出し量は等しいとする。ａは係数であるが、重みの合計を１とすることから、

Here, it is assumed that the amount of energy blown out in each air conditioning zone is equal. Although a is a coefficient, since the total weight is set to 1,

これによって、ａは次のように求められる。

Accordingly, a is obtained as follows.

この具体的に求めたａの値を上述の投票の重みａ／ｄ_１ ^２，ａ／ｄ_２ ^２，ａ／ｄ_３ ^２，ａ／ｄ_４ ^２をそれぞれ代入することで、距離に応じた各重み付けの具体的な値がそれぞれ求まる。そして、この値と各在席者の投票結果とから最適な温度調整量を求めることができる。

By substituting the above-mentioned voting weights a / d ₁ ² , a / d ₂ ² , a / d ₃ ² , and a / d ₄ ² respectively for the value of a specifically obtained, Specific values for weighting are obtained. The optimum temperature adjustment amount can be obtained from this value and the vote result of each attendee.

For example, in the example of FIG. 10, a / d ₁ ² = 0.4, a / d ₂ ² = 0.4, a / d ₃ ² = 0.1, and a / d ₄ ² = 0.1. .

  Hereinafter, a point of interest that clarifies the usefulness of the above-described embodiment of the present invention will be described.

  The terminal used by the operator is equipped with a position detection function, and when the terminal is operated (when the intention of “hot” or “cold” is displayed as a majority vote participation), the operator and the Calculate the distance to the center of multiple nearby air conditioning zones. For example, assuming that the operator is in a position corresponding to four zones A, B, C, and D, distances DA, DB, DC, and DD to the center of each air conditioning zone are calculated. The air conditioning system side receives one vote for the majority vote of the operator according to the distance to the center of the air conditioning zone. As a result, even if the operator is located near the boundary between a plurality of air conditioning zones, it is not necessary to participate in majority voting that is biased to any one air conditioning zone. It can be improved. For example, the closer the distance to the center of the air-conditioning zone, the larger the weight, and the total of the weights may be set to 1.0 corresponding to one vote.

  In addition, when there is one operator, it functions substantially as a “personal large space air conditioning method”.

  And, if configured as described above, it may happen that a large number of votes for weighted majority vote are gathered by chance, and an air conditioning facility that does not substantially affect any operator may operate. become. That is, for example, if 20 votes having a weight of about 0.05 are collected, an intention display for one vote is accepted.

  If the distance to the center of the air-conditioning zone is simply followed, such a numerical value is obtained. On the other hand, it is desirable that air-conditioning reduces unnecessary operations as much as possible. Therefore, in order to make this unlikely to occur, the inventor has noted that only air-conditioning zones whose weights are equal to or greater than a predetermined threshold should be limited to application targets.

  This can reduce unnecessary (or less effective) air conditioning operations.

  For example, assuming that the operator is in a position corresponding to four zones A, B, C, and D, the weights for each zone are first obtained as 0.44, 0.22, 0.22, and 0.12, respectively, by simple calculation. To do. When the predetermined threshold is 0.20, 0.44, 0.22, and 0.22 of A, B, and C are adopted. Since the sum of the three numerical values at this time is 0.88, normalization is performed so that the sum is 1.0. That is, each numerical value is multiplied by 1.0 / 0.88, and the weights are determined as 0.50, 0.25, 0.25 only for the zones A, B, and C, and the total weight is one vote. become. And extremely small numbers will be excluded.

  Then, the 1st modification of embodiment of this invention is demonstrated. In addition, about the structure equivalent to embodiment of this invention, a corresponding code | symbol is attached | subjected and detailed description is abbreviate | omitted. FIG. 12 is a block diagram showing a first modification of the environment adjustment system shown in FIG. FIG. 13 is an explanatory view different from FIGS. 10 and 11 for explaining the control method of the environmental adjustment system shown in FIG.

  In this first modification, unlike the embodiment of the present invention, each terminal is worn by a person rather than a fixed terminal of a type that is installed in a specific place such as a desk or a chair where the terminal performs the work of a resident ( It consists of a remote control type mobile terminal 300 (300-1, 300-2, 300-3,...) That can walk around the area. Then, each person carries the mobile terminal (remote controller) 300 one by one, and the control calculation of the embodiment of the present invention is performed via each receiving device 260 (260-1, 260-2, 260-3,...). Similarly to the unit 251, the control calculation unit 290 weights the information based on the information from each person's mobile terminal 300, and the air conditioners 270 (270-1, 270-2, 270-assigned to each zone). 3,...) Is controlled so that each zone has an optimum temperature.

  In this modification, unidirectional communication is performed from the mobile terminal 300 to the air conditioner 160 via the wireless reception unit 262. Accordingly, the mobile terminal 300 includes a timer A shown in the flowchart of FIG. 4, and the air conditioner 270 includes a timer B shown in the flowchart of FIG. However, this modification is not limited to unidirectional communication, and bidirectional communication is also applicable. In that case, the timer A of the mobile terminal becomes unnecessary.

  As shown in FIG. 13, each air conditioning zone whose temperature is adjusted by each air conditioner 270 may be further divided into small air conditioning zones. Specifically, the air conditioning zone is further divided into small sections, and when there is another mobile terminal in the small section where the mobile terminal exists, the control calculation unit 290 reduces the voting weight. .

  The reason is as follows. Within one air conditioning zone, the temperature may not be uniform depending on the location. There are places where it is difficult to adjust the thermal environment, for example, near a window, near an entrance, near a heat source, and the like. In such a case, one operator does not have one vote equally, but considers one vote for each place. For example, if there is only one person in the small section, one vote per person, but if there are three persons in the small section, if the air conditioner 270 is heating, for example, there is another heat source and the air conditioner 270 is Considering that it is difficult to adjust the thermal environment of the small section, there will be 1/3 votes per person. In this way, the set value is determined fairly. In the case of FIG. 13, there are only one resident A1 in the upper left subcompartment zone and three occupants B, C, and D in the lower right subcompartment zone. Is set to 1, and the weight of information from the occupants B, C, and D is set to 0.33, respectively, and the set value is determined fairly.

  Then, the 2nd modification of embodiment of this invention is demonstrated. In addition, about the structure equivalent to embodiment of this invention and its 1st modification, corresponding code | symbol is attached | subjected and detailed description is abbreviate | omitted. FIG. 14 is a block diagram showing a second modification of the environment adjustment system shown in FIG.

  In this modification, unidirectional communication is performed from the mobile terminal 300 to the control calculation unit 290 via the wireless reception unit 262. Accordingly, the mobile terminal 300 includes a timer A shown in the flowchart of FIG. 4, and the control calculation unit 290 includes a timer B shown in the flowchart of FIG. However, this modification is not limited to unidirectional communication, and bidirectional communication is also applicable. In that case, the timer A of the mobile terminal becomes unnecessary.

  Unlike the first modification of the embodiment of the present invention, the second modification is provided with a human detection sensor (human sensor) 305 in the mobile terminal 300. When the presence sensor 305 detects only when the occupant is carrying the mobile terminal 300 and the occupant is carrying the mobile terminal 300 and the vote for changing the temperature setting is not made within a predetermined time. Sends a signal indicating that the current temperature management state is accepted to the control arithmetic unit 290 via each receiving device 260 (260-1, 260-2, 260-3,...). . Therefore, if the occupant is not carrying the mobile terminal 300, for example, if it remains on the desk, the person detection sensor 305 determines that the occupant is not carrying the mobile terminal 300. If the temperature setting change voting signal does not reach the control calculation unit 290 within a predetermined time, it is determined that the change request regarding the temperature management of the person or the voting for the acceptance has not been made.

  In each of the above-described embodiments and their modifications, the control calculation unit sets the change value to zero when the calculated setting change value is smaller than a predetermined value of about 1 ° C. with respect to the current setting temperature, for example. Is good.

  By giving small setting change values to the surrounding air conditioning zones, wasteful air conditioning energy is generated, but the control calculation unit sets the change value to zero when the calculated setting change value is less than or equal to a predetermined value. The generation of such wasteful air conditioning energy is prevented.

  In the above-described embodiment of the present invention and each modification thereof, each terminal may be provided with a temperature sensor as in the third modification of the reference embodiment. Thus, the temperature measured via the temperature sensor is sent to the control device, and the control device collects the temperature data sent from each terminal, calculates the average temperature data, and based on this average temperature data, it is used for air conditioning control. It is possible to control the room temperature through the air conditioner by correcting the calculation result.

  In addition, each of the above-described embodiments and modifications thereof have been introduced so that the terminal and the control device communicate wirelessly. However, if the terminal is a fixed terminal fixed to, for example, a chair or a desk, the wireless communication is not necessarily performed. There is no need to communicate, and the terminal and the control device may communicate with each other by wire.

  Moreover, about each above-mentioned embodiment and each modification, although the air-conditioning environment adjustment system which is one of the environment adjustment systems was introduced, this invention is not limited to this air-conditioning environment adjustment system. Specifically, the environment adjustment system according to the present invention can be widely applied to lighting environments, acoustic (BGM, etc.) environments, and the like.

  As described above, the area is divided into a plurality of air conditioning zones that are respectively controlled by a plurality of air conditioners, and the control calculation unit specifies the position of the terminal from the terminal number of each operator created in advance, The data of each terminal is aggregated and calculated, the vote is weighted according to the distance from the center of each air conditioning zone of the transmission position of each terminal, the setting change value of each air conditioner is calculated, and the result is the air conditioning control unit , You can vote not only for one air conditioning zone, but also for all affected air conditioning zones according to the distance, so that the temperature will be more comfortable for you. The air conditioning of the area can be controlled.
