The device control device 121Aa includes a display processing means 122, an absence information detecting means 123, a device communication means 124, an input information processing means 125, and a seat position detecting means 202Aa.

The display processing means 122 controls the display state of the display device 41. The display processing means 122 causes the display device 41 to display a scheduler screen or the like indicating the schedule of the individual 402Aa in response to the operation signal from the input device 42. The display processing means 122 reflects the setting contents by the input information processing means 125 and causes the input device 42 to display the scheduler screen.

The absence information detecting means 123 acquires a detection signal transmitted from the control device 101 via the device communication means 124. Then, the presence / absence information detecting means 123 reads the presence / absence information at the time corresponding to the detection signal from the control device 101 from the storage device 43, and sends the read absence / absence information to the control device 101 via the device communication means 124. It will be returned. Here, the absence information is information indicating the presence or absence of a person having a seat in the air-conditioned area. More specifically, the absence information includes "equivalent to being in the room" corresponding to the state in which the individual 402Aa is present and "equivalent to absence" corresponding to the state in which the individual 402Aa is away from the seat 404Aa. ..

The device communication means 124 transmits and receives communication data to and from the control device 101 via a communication means such as a communication line or wireless.

The absence / absence information processing means 125y sets the absence / absence information at the time corresponding to the information of the schedule item stored in the schedule item processing means 125x to “absence equivalent”. On the other hand, the absentee information processing means 125y sets the absentee information at a time when the information of the scheduled item is not input to "equivalent to being in the room". This is because it is considered that the individual 402Aa is working at his / her own seat during the time zone when the individual 402Aa does not enter the schedule.

That is, the schedule information is information in which the time information, the schedule item information, and the absence information are associated with each other. Therefore, the absence information detecting means 123 reads and outputs the absence information corresponding to the absence state of the individual 402Aa from the schedule information based on the schedule input by the individual 402Aa. Here, the device control device 121Aa can be configured by an operation program including an arithmetic unit such as a microcomputer and scheduler software that realizes each of the above functions in cooperation with the arithmetic unit.

In addition, in the area identification information, the information device and the seat are associated with each other. In FIG. 4, the information device 401Aa and the seat 404Aa are associated with each other. In FIG. 5, the information devices 401Aa to 401Ad and the seats 404Aa to 404Ad are associated with each other on a one-to-one basis.

The calculation means 102 performs a calculation related to the determination of the air conditioning operation of the air conditioner 301A by using the control parameters acquired from the device control device 121Aa and the air conditioner control device 141A according to various calculation algorithms stored in the storage means 104. It is something to do. The calculation means 102 includes an area specifying means 102x, a presence / absence determining means 102y, and a presence / absence determining means 102z.

The area specifying means 102x requests the seat position detecting means 202Aa to return the seat identification information. Further, the area specifying means 102x requests the air conditioner position detecting means 203A to return the air conditioning identification information. The area specifying means 102x can detect the air-conditioned area in which the information device 401Aa is arranged by comparing the seat identification information acquired from the seat position detecting means 202Aa with the area specifying information. Further, the area specifying means 102x can detect the air conditioning area in which the air conditioner 301A is arranged by comparing the air conditioning identification information acquired from the air conditioner position detecting means 203A with the area specifying information. That is, the area specifying means 102x can detect that the air conditioner 301A and the seat 404Aa are arranged in the same air conditioning area 403A by using the seat identification information and the air conditioning identification information.

The presence / absence determining means 102y determines whether or not a person exists in the air-conditioned area 403A based on the information detected by the personal position detecting means 201A. The presence / absence determining means 102y acquires the information detected by the personal position detecting means 201A over time via the communication means 105.

The absence determination means 102z determines whether the presence / absence information of a person having a seat in the air-conditioned area 403A indicates the presence or absence of a room when the presence / absence determination means 102y determines that no person exists. be. The presence / absence determination means 102z determines that the presence / absence information indicates the presence of the room if the presence / absence information is “equivalent to the presence of the room”, and determines that the absence / absence information indicates the absence.

More specifically, when the presence / absence determination means 102y determines that the individual 402Aa does not exist, the presence / absence determination means 102z detects the presence / absence information via the communication means 105 with a detection signal requesting the detection of the absence / absence information. It is transmitted to means 123. Then, in the absence determination means 102z, the absence information indicates the presence or absence of the room depending on whether the absence information returned from the absence information detecting means 123 is "equivalent to being in the room" or "equivalent to being absent". Is determined.

The control means 103 generates a command signal including information on the control contents of the air conditioner 301A based on the result of the calculation by the calculation means 102. Then, the control means 103 controls the air conditioner 301A by outputting the generated command signal to the air conditioner control device 141A via the communication means 105.

More specifically, the control means 103 controls the operation of the air conditioner 301A according to the result of the determination by the absence determination means 102z. When the presence / absence information is determined by the absence / absence determining means 102z, the control means 103 reduces the power consumption of the air conditioning operation of the air conditioner 301A as compared with the case where a person exists in the air conditioning area 403A. It is intended for operation. On the other hand, the control means 103 continues the operation of the air conditioner 301A when the presence / absence information is determined by the presence / absence determination means 102z to indicate the presence / absence of the room. That is, the control means 103 does not detect a person in the air conditioning area 403A by the personal position detecting means 201A while the air conditioner is operating, and at least one of the people who has a seat in the air conditioning area 403A is absent. When the information indicates the presence of the room, the operation of the air conditioner 301A is continued. In the case of FIG. 1, all persons having seats in the air-conditioned area 403A are individuals 402Aa.

Further, the control means 103 can perform control for relaxing the set temperature of the air conditioner 301A by a predetermined temperature as an absent operation of the air conditioner 301A. As the control for relaxing the set temperature of the air conditioner 301A, for example, it is possible to adopt a control in which the set temperature is raised by a predetermined temperature in the cooling operation mode and the set temperature is lowered by a predetermined temperature in the heating operation mode. can. As a result, the control means 103 can realize control such as changing the set temperature from 26 ° C. to 28 ° C. by switching to the absent operation, for example, in the cooling operation mode. The control content of the absentee operation by the control means 103 may be set according to the installation environment of the air conditioning system 100 and the like, and may be appropriately changed according to the change of seasons and the like.

The communication means 105 inputs communication data from the device control device 121Aa and the air conditioner control device 141A via a communication means such as a communication line or wireless. Further, the communication means 105 outputs information such as a command signal generated by the control means 103 to the air conditioner control device 141A.

Here, with reference to the configuration example of FIG. 2, the case where the control device 101 manages the operation of each of the plurality of air conditioners and the operation of each of the plurality of information devices will be supplemented. In the case of the configuration of FIG. 2, the area specifying means 102x acquires the seat identification information from each of the seat position detecting means 202Aa to 202Ad and 202Ba to 202Bd. Further, the area specifying means 102x acquires air conditioning identification information from each of the air conditioner position detecting means 203A and 203B. Then, the area specifying means 102x detects the correspondence between each air conditioning area, each air conditioner, and each information device by illuminating each seat identification information and each air conditioning identification information with the area identification information.

The existence / non-existence determination means 102y analyzes the information detected by the personal position detecting means 201A based on the information detected by the area specifying means 102x, and each of the individuals 402Aa to 402Ad exists in the air-conditioned area 403A. Judge whether or not. Similarly, the presence / absence determining means 102y analyzes the information detected by the personal position detecting means 201B to determine whether or not each of the individuals 402Ba to 402Bd exists in the air-conditioned area 403B.

When the presence / absence determination means 102z determines that no person exists, the presence / absence determination means 102z is based on the information detected by the area identification means 102x, and the presence / absence of all persons having seats in the air-conditioned area 403A. Determine whether the information indicates presence or absence. Similarly, the absence determination means 102z determines whether the presence / absence information of all persons having seats in the air-conditioned area 403B indicates the presence or absence of the room.

When it is determined by the absence determination means 102z that the absence information of all the people who have seats in the air conditioning area 403A indicates the absence, the control means 103 causes the air conditioner 301A to execute the absence operation. In the case of FIG. 2, all persons having seats in the air-conditioned area 403A are individuals 402Aa to 402Ad. Further, the control means 103 causes the air conditioner 301A to execute the absence operation when the presence / absence determination means 102z determines that the absence information of all the persons having seats in the air conditioning area 403B indicates the absence. In the case of FIG. 2, all persons having seats in the air-conditioned area 403B are individuals 402Ba to 402Bd.

The control means 103 continues the operation of the air conditioner 301A when it is determined by the presence / absence determination means 102z that the presence / absence information of at least one of the persons having a seat in the air conditioning area 403A indicates the presence / absence of the room. That is, the control means 103 does not detect a person in the air conditioning area 403A by the personal position detecting means 201A while the air conditioner is operating, and at least one of the people having a seat in the air conditioning area 403A is absent. When the information indicates the presence of the room, the operation of the air conditioner 301A is continued.

Further, the control means 103 continues the operation of the air conditioner 301B when the presence / absence determination means 102z determines that the presence / absence information of at least one of the persons having a seat in the air conditioning area 403B indicates the presence / absence of the room. Let me. That is, the control means 103 does not detect a person in the air conditioning area 403B in the personal position detecting means 201B while the air conditioner is operating, and at least one of the people who has a seat in the air conditioning area 403B is absent. When the information indicates the presence of the room, the operation of the air conditioner 301B is continued.

(System operation mode)
The air conditioning system 100 has a cooling operation mode and a heating operation mode as the operation modes of the air conditioner 301A. The air conditioner 301A mainly supplies cold air to the room by the cooling operation mode when the indoor set temperature is lower than the outside air temperature, and warms the room by the heating operation mode when the indoor set temperature is higher than the outside air temperature. By supplying wind, the temperature of the air conditioning area 403A is adjusted. The same applies to the air conditioner 301B in the case of FIG. 2.

(Scheduler screen)
FIG. 6 is an explanatory diagram showing an example of a scheduler screen displayed on the display unit of the information device of FIG. FIG. 6 shows an example of inputting an attendance schedule by an individual 402Aa. The display device 41 can display the scheduler screen as illustrated in FIG. 3 by starting the scheduler software installed in the information device 401Aa. The display of the scheduler screen on the display device 41 is performed by the display processing means 122 in response to an input operation on the input device 42.

On the scheduler screen, the time within the display range is displayed at regular time intervals in the "time" column. FIG. 6 illustrates a case where the range from 8:00 to 21:00 is set as the display range. Further, in FIG. 6, the time within the display range is displayed at an interval of 1 hour.

On the scheduler screen, the content of the schedule input via the input device 42 is displayed in the "scheduled item" field in association with the "time" field. In FIG. 6, "meeting" is displayed in the time zone from 9:00 to 11:00 and 15:00 to 17:00, and "meeting" is displayed in the time zone from 14:00 to 14:30. Has been done. That is, the display processing means 122 reflects the setting contents by the scheduled item processing means 125x on the scheduler screen.

On the scheduler screen, the information corresponding to the absence information is displayed in the "absence status" column. That is, the display processing means 122 displays "absence" in the time zone in which the absence / absence information processing means 127 sets the absence / absence information to "absence equivalent", and the absence / absence information processing means 127 displays the absence / absence information as "absence". "Available" is displayed during the time period set to "Equivalent to occupancy". In FIG. 6, "absence" is performed in the time zone from 9:00 to 11:00, the time zone from 14:00 to 14:30, and the time zone from 15:00 to 17:00 when the information of the scheduled item is input. Is displayed. On the other hand, "in-room" is displayed in the time zone when the information of the scheduled item is not input. That is, the display processing means 122 reflects the setting contents by the absent information processing means 125y on the scheduler screen.

Here, the personal 402Aa or the like can input the schedule via the input device 42 with the scheduler screen displayed on the display device 41. For example, when the personal 402Aa inputs information indicating that the meeting is from 9:00 to 11:00, the absent information processing means 125y determines that the time zone from 9:00 to 11:00 is absent. The absence information of the time zone is set to "absence equivalent". Therefore, the display processing means 122 displays "absent" in the time zone from 9:00 to 11:00 on the scheduler screen. That is, the information in the absence status column of the scheduler screen is automatically updated on the software.

As described above, the scheduler screen is configured to include time information, schedule item information associated with the time information, and information corresponding to the absence information. Here, the scheduler screen may be configured without including the information corresponding to the absence information. However, if the information corresponding to the absence information is displayed on the screen of the display device 41, the individual or the like who has input the schedule can recognize the determination status of the absence state. That is, if the scheduler screen includes the information corresponding to the absence information, it is possible to avoid unintended operation control of the air conditioner, so that energy saving and comfort can be improved.

FIG. 7 is a flowchart showing the operation of the air conditioning system of FIG. Based on FIG. 7, an air conditioning operation control method in consideration of the absence information by the air conditioning system 100 will be described. The processing shown in FIG. 7 is executed by the calculation means 102 of the control device 101. Here, the processing of the air conditioning area 403A based on the configuration of FIG. 2 will be described.

First, the calculation means 102 acquires the detection information by the personal position detection means 201A (step S101). Then, the calculation means 102 determines whether or not a person exists in the air-conditioning area 403A based on the acquired detection information (step S102).

When a person exists in the air conditioning area 403A (step S102 / Yes), the calculation means 102 puts the air conditioner 301A into an operating state via the control means 103. That is, the calculation means 102 starts the air conditioning operation of the air conditioner 301A through the control means 103 when the air conditioner 301A is stopped, and when the air conditioner 301A is in operation, the calculation means 102 of the air conditioner 301A through the control means 103. The operation is continued (step S103).

On the other hand, when the calculation means 102 does not have a person in the air-conditioned area 403A (step S102 / No), does the calculation means 102 indicate the absence information of all the individuals 402Aa to 402Ad who have seats in the same air-conditioned area 403A at the current time? It is determined whether or not (step S104). When the presence / absence information of the individuals 402Aa to 402Ad all indicate the absence, the calculation means 102 causes the air conditioner 301A to execute the absence operation (step S105). When at least one of the presence / absence information of the individuals 402Aa to 402Ad indicates the presence / absence of the individual, the calculation means 102 proceeds to the process of step S103.

The calculation means 102 repeatedly executes a series of processes of steps S101 to S105 over time. When the control device 101 manages the air conditioners in the plurality of air-conditioned areas, the calculation means 102 executes a series of processes of steps S101 to S105 for each of the plurality of air-conditioned areas in the same manner as described above. That is, in the case of the configuration of FIG. 2, the same processing as described above is executed for the air conditioning area 403B as well.

As described above, the air conditioning system 100 is air-conditioned even if there are no people in the air-conditioned area, as long as the presence / absence information of at least one of the people who have seats in the air-conditioned area indicates the presence of the room. Continue the operation of the aircraft. Therefore, it is possible to improve the accuracy of determining the presence or absence of a person and reduce the amount of power consumption. That is, according to the air conditioning system 100, by controlling the air conditioner using the schedule information input by the individual together with the sensing data indicating the absence, the absence determination is made rather than the absence determination based on the prediction based on the past data. The accuracy of the

By the way, in the air conditioning system 100, it is necessary for an individual to input a schedule, but it is common in an individual's business to input and manage the schedule using a scheduler. That is, since the schedule input by the individual in the air conditioning system 100 is a diversion of what is performed in the normal work as it is, it does not pose a special work load. The schedule information is based on a schedule that is input by an individual and updated when necessary, and is managed daily by the individual, so that the information is highly reliable.

Therefore, since the air conditioning system 100 can accurately detect the time zone when a person is absent, the air conditioner does not frequently repeat the air conditioning operation and the stop operation, and the power consumption can be reduced. That is, since the air conditioning system 100 controls ON / OFF of the air conditioning operation by utilizing the schedule information, the air conditioner does not stop even if the person leaves the seat in a short time such as going to the toilet. Therefore, the operation is stable, and the start-up loss caused by changing the air conditioner from the stop to the air-conditioning operation can be eliminated, so that the power consumption can be reduced. Further, since the air conditioning system 100 directly determines the presence / absence from the schedule of the day entered by the individual, it is not necessary to accumulate the past data. Therefore, the memory capacity can be reduced and the control algorithm can be simplified, so that the development cost can be reduced.

Here, work such as meetings that leave the desk for a long time does not have a high periodicity, and often behaves differently from the past. The periodicity here refers to the property of occurring at the same time on the same day of the week every week. Therefore, in the air conditioning system of Patent Document 1, an erroneous determination regarding the presence or absence of a person occurs, and the power consumption increases. On the other hand, since the air conditioning system 100 performs air conditioner operation control depending on the input information of the current time, it is possible to determine the absence for a long period of time with high accuracy, and the air conditioner can be operated at an appropriate timing. Can be stopped.

<Modification example>
FIG. 8 is a block diagram of a control system of an air conditioning system according to a modified example of the first embodiment of the present invention. Since the overall configuration of the air conditioning system of this modification is the same as that of the air conditioning system 100 described above, the same reference numerals are used for equivalent components, and the description thereof will be omitted.

In the air conditioning system 200 of this modification, the device control device 121Aa of the information device 401Aa has the presence / absence information adjusting means 125z as an internal configuration of the input information processing means 125. Other configurations of the air conditioning system 200 are similar to those of the air conditioning system 100, as shown in FIG. The absentee information adjusting means 125z adjusts the absentee information set by the absentee information processing means 125y according to the length of the time zone of the scheduled item set by the scheduled item processing means 125x. Here, as described above, each individual can input the schedule item via the input device 42. Therefore, the length of the time zone of the scheduled item corresponds to the "time away from the seat entered by a person having a seat in the air-conditioned area" of the present invention.

More specifically, the absentee information adjusting means 125z maintains the absentee information as "absence equivalent" if the length of the time zone of the scheduled item is longer than the occupancy set time. On the other hand, the absence / absence information adjusting means 125z corrects the absence / absence information from "absence equivalent" to "room equivalent" if the length of the time zone of the scheduled item is equal to or less than the occupancy set time. Therefore, the display processing means 122 of this modification causes the display device 41 to display the scheduler screen based on the absence information after being adjusted by the absence information adjusting means 125z. Here, the occupancy setting time is set to, for example, 30 minutes and can be changed as appropriate.

(Scheduler screen)
FIG. 9 is an explanatory diagram showing an example of a scheduler screen displayed on the display unit of the information device of FIG. Since the scheduler screen is configured in the same manner as the example of FIG. 6, the points different from those of FIG. 6 will be described here. In FIG. 9, it is assumed that the occupancy setting time is set to 30 minutes.

In the case of FIG. 9, the length of the time zone from 14:00 to 14:30 is 30 minutes, which is equal to or less than the occupancy set time. Therefore, the absence information adjusting means 125z has a time of 14:00 to 14:30. The absence information corresponding to the band is corrected from "absence equivalent" to "room equivalent". Therefore, in the display processing means 122, since the absence information corresponding to the time zone from 14:00 to 14:30 is "equivalent to being in the room", the time zone from 14:00 to 14:30 on the scheduler screen "Available" is displayed in the absentee status column corresponding to. Therefore, unlike the case of FIG. 6, in the absence state column of the scheduler screen of FIG. 9, the entire time zone from 11:00 to 15:00 including the time zone from 14:00 to 14:30 is "present". "Room" is displayed.

Here, when the air conditioning system 200 adopts the same configuration as the air conditioning system 100 of FIG. 2, the information devices 401Ab to 401Ad and 401Ba to 401Bd are respectively configured in the same manner as the information device 401Aa shown in FIG. ..

FIG. 10 is a flowchart showing the operation of the information device of FIG. Based on FIG. 10, a method of determining the presence / absence information for the scheduled time zone performed by the device control device 121Aa will be described. Since the processing contents of the information devices 401Aa to 401Ad and 401Ba to 401Bd are the same, here, the processing when the individual 402Aa inputs a schedule to the information device 401Aa while the display device 41 displays the scheduler screen. Will be described.

First, the individual 402Aa inputs a schedule item in association with the time (step S201). Then, the input information processing means 125 sets the schedule item and the absence information. That is, the input information processing means 125 stores the information of the scheduled item in the storage device 43, and sets the absence information corresponding to the time when the scheduled item is input to "absence equivalent" (step S202).

Next, the input information processing means 125 determines whether or not the length of the time zone of the scheduled item is longer than the occupancy set time (step S203). When the length of the time zone of the scheduled item is longer than the occupancy set time (step S203 / Yes), the input information processing means 125 corrects the absence information corresponding to the input scheduled item to "absence equivalent". (Step S204). Then, the display processing means 122 sets the absentee state corresponding to the input scheduled item as “absent” on the scheduler screen (step S205).

On the other hand, when the length of the time zone of the scheduled item is equal to or less than the occupancy set time (step S203 / No), the input information processing means 125 sets the presence / absence information corresponding to the input scheduled item to "equivalent to occupancy". Leave as (step S206). Then, the display processing means 122 sets the presence / absence state corresponding to the input scheduled item as “in-room” on the scheduler screen (step S207).

In the air conditioning system 200 of this modification, when the length of the time zone of the scheduled item is less than or equal to the set time in the room, the presence / absence information corresponding to the input scheduled item remains "equivalent to the room". Therefore, the calculation means 102 of the control device 101 can control the operation of the air conditioner based on the presence / absence information adjusted on the information device side. Therefore, for example, when there are many schedules that leave the seat but the time to leave the seat is relatively short, such as a small internal meeting, the absence state of those schedules can be maintained as "equivalent to being in the room". Therefore, since it is possible to suppress the frequent ON / OFF of the air conditioning of the air conditioner, it is possible to suppress an increase in power consumption due to unstable operation. In addition, since the room temperature can be maintained when the person leaves the seat for a relatively short period of time, personal comfort can be enhanced.

By the way, in this modification, the configuration in which the input information processing means 125 temporarily sets the presence / absence information by the presence / absence information processing means 125y and then adjusts the presence / absence information by the presence / absence information adjusting means 125z is illustrated. Not limited to this. After setting the scheduled item, the input information processing means 125 may set the absence information according to the length of the time zone of the scheduled item. That is, referring to the flowchart of FIG. 10, the input information processing means 125 may set only the scheduled items in step S202. Then, in the case of Yes in step S203, the input information processing means 125 may set the absence information to "absence equivalent" in step S204. Further, when the input information processing means 125 is No in step S203, the presence / absence information may be set to "equivalent to being in the room" in step S206.

Embodiment 2.
FIG. 11 is a schematic view showing an example of the configuration of the air conditioning system according to the second embodiment of the present invention. FIG. 11 is an example of a view of the horizontal plane of the installation space 403 from the ceiling side. In FIG. 11, there are seven sets of information devices in the installation space 403, seats, and individuals corresponding to the seats, and the area of the installation space 403 is divided into an air-conditioning area 403A and an air-conditioning area 403B. The division of the air-conditioned area is determined in the same manner as in the case of FIG. That is, in the air conditioning system 300, there are four sets of information devices, seats, and individuals corresponding to the seats in the air-conditioned area 403A, and three sets in the air-conditioned area 403B. The same reference numerals are given to the configurations equivalent to those of the first embodiment described above, and the parts different from those of the first embodiment will be described.

The air conditioning system 300 includes control devices 111, air conditioners 301A and 301B, information devices 411Aa to 411Ad and 411Ba to 411Bc, and personal cards 161Aa to 161Ad and 161Ba to 161Bc carried by each individual. That is, each individual 402Aa to 402Ad and 402Ba to 402Bc have individual cards 161Aa to 161Ad and 161Ba to 161Bc, respectively, and input the information of each individual card to the control device 101.

The information devices 411Aa to 411Ad and 411Ba to 411Bc are configured in the same manner as the information devices 401Aa of the first embodiment, and are assigned to the individuals 402Aa to 402Ad and the individuals 402Ba to 402Bc, respectively. Scheduler software is installed in each of the information devices 411Aa to 411Ad and 411Ba to 411Bc. The seat position detecting means 202Aa is mounted on the information device 411Aa. The information devices 411Ab to 411Ad and 411Ba to 411Bc are equipped with seat position detecting means 202Ab to 202Ad and 202Ba to 202Bc, which are configured in the same manner as the seat position detecting means 202Aa, respectively.

The air conditioner 301A located in the air conditioning area 403A has the air conditioner position detecting means 203A which is an ID tag for the air conditioner, and the ID tag for the seat in the same air conditioning area 403A is the seat position detecting means. It is 202Aa to 202Ad. Further, the air conditioner 301B located in the air conditioning area 403B has the air conditioner position detecting means 203A which is an ID tag for the air conditioner, and the ID tag for the seat in the same air conditioning area 403A is the seat position. The detection means 202Ba to 202Bc.

FIG. 12 is a block diagram of the control system in the air conditioning system of FIG. Based on FIG. 12, the functional configurations of the information device 411Aa, the control device 111, the air conditioner 301A, and the personal card 161Aa will be described. Here, since the information devices 411Ab to 411Ad and 411Ba to 411Bc shown in FIG. 12 are configured in the same manner as the information devices 411Aa, the description thereof will be omitted. Further, since the personal cards 161Ab to 161Ad and 161Ba to 161Bc are configured in the same manner as the personal cards 161Aa, the description thereof will be omitted.

The personal card 161Aa is equipped with personal identification means 162Aa and entry / exit notification means 163Aa. The personal identification means 162Aa is an ID tag that stores personal identification information that is identification information of the personal card 161Aa, and includes a number that is combined with the seat identification information of the seat position detecting means 202Aa that is an ID tag for a seat. Has been granted. The personal identification means 162Aa returns the personal identification information in response to a request from the control device 111. Therefore, the control device 111 can identify who is the individual who entered the schedule.

The entry / exit notification means 163Aa notifies the control device 111 or the like that an individual has entered or exited the building having the air-conditioned area or the area where the building is built. For example, when the personal card 161Aa is held over the entrance gate in the building, the entrance / exit notification means 163Aa notifies the control device 111 of the entrance / exit of the individual having the personal identification information of the personal card 161Aa through the entrance gate. .. When an individual 402Aa who is an office worker holds the individual card 161Aa over the entrance gate of the building containing the company, the individual card 161Aa notifies the control device 111 of the arrival or departure of the individual 402Aa. The personal card 161Aa may be a dedicated card having each of the above functions, or an employee ID card to which each of the above functions is given.

Further, the device control device 121Aa of the second embodiment has an input person identification means 125Aa. The input person identification means 125Aa is an ID tag including job title identification information for identifying the job title of the individual who has entered the schedule. The job title identification information is associated with the seat identification information of the seat position detecting means 202Aa. The control device 111 can identify whether the individual who entered the schedule is a manager such as a manager or a person in charge such as a general employee based on the job title identification information of the input person identification means 125Aa. can. That is, the control device 111 can identify whether or not the seat of the individual who entered the schedule belongs to the manager. Here, the job title identification information corresponds to the "manager identification information" of the present invention indicating whether or not the person who has a seat in the air-conditioned area is the manager.

Further, the calculation means 102 of the second embodiment has a manager determination means 102m for determining whether or not there is a manager's seat in the air-conditioned area from the job title identification information. The manager determining means 102m determines whether or not there is a manager's seat in each of the air-conditioned areas 403A and 403B by analyzing the job title identification information of the information devices 411Aa to 411Ad and 411Ba to 411Bc. be.

In addition, the manager determination means 102m acquires the personal identification information of each of the personal cards 161Aa to 161Ad and 161Ba to 161Bc. Then, the manager determination means 102m determines whether or not the administrator exists in the air-conditioned area where the administrator's seat is located, based on the acquired personal identification information.

Here, in the control means 103 of the second embodiment, when the manager determination means 102m determines that the manager's seat is in the air-conditioned area, the personal position detecting means detects the manager in the air-conditioned area. If the absence information of the manager indicates the absence, the air conditioning operation of the air conditioner in the air conditioning area is regarded as the absence operation.

In addition, the calculation means 102 of the second embodiment has an entry / exit reflection means 125 m that reflects the entry / exit status of an individual in the presence / absence information. When the personal card 161Aa is held over the entrance gate or the like, the entry / exit reflection means 125m acquires entry / exit information indicating entry or exit of each individual via the control device 111. Then, the entry / exit reflection means 125m corrects the absence / absence information based on the acquired entry / exit information.

More specifically, when the entry / exit reflection means 125m acquires the entry / exit information indicating each individual's "exit", the presence / absence information on the day after the acquisition time includes "equivalent to being in the room". However, the absence information of the day after the time is corrected to "absence equivalent". The entrance / exit reflection means 125m stores the entrance / exit information indicating each individual's entrance in an internal memory or the like, and whether or not each individual is entering at the timing when the scheduled work time comes. May be determined. Then, if there is an individual who is not in the entrance, it is advisable to always set the absence information of the individual on the day to "equivalent to absence". Then, when the entry / exit information indicating the entry of the individual is acquired during the day due to reasons such as being late, it is advisable to return the absence information to the original state at that time.

Here, the air conditioning system 300 of the second embodiment can apply the configuration according to the modified example of the first embodiment. That is, the input information processing means 125 may have the absence information adjusting means 125z. Further, the air conditioning system 300 can also improve the accuracy of determining the presence or absence of a person and reduce the power consumption, as in the air conditioning system 100 of the first embodiment.

(Operation control of air conditioners considering job title)
Since the air conditioning system 300 has the above configuration, it is possible to control the operation of the air conditioner in consideration of the job title. Here, based on the configuration example of FIG. 11, it is assumed that the seats of one organization are arranged in the installation space 403 such as the office. In such situations, personnel are often grouped together and managers are often placed apart across an aisle. In the second embodiment, specifically, it is assumed that the individuals 402Aa to 402Ad and 402Ba to 402Bb are the persons in charge, and the individuals 402Bc are the managers.

By the way, in the first embodiment, the air conditioner is not stopped unless all the people in the air conditioning area are absent. That is, for example, when the configuration of the first embodiment is applied to the air conditioning area 403B of FIG. 11, the air conditioner 301B is stopped unless at least all the individuals 402Ba to 402Bb who are in charge and the individuals 402Bc who are the managers are absent. It does not become a state. In this regard, after the end of business hours, although there are differences in the degree of backlog processing, many individuals leave the company, so even with the configuration of the first embodiment, there is an opportunity to stop the air conditioner. However, during business hours, the absence of all individuals with seats in the air-conditioned area is limited to limited cases such as group meetings, which are meetings by all groups. Such cases are limited to once or twice a week at most, and the timing of stopping the air conditioner during business hours in the office does not actually occur so often.

On the other hand, the manager needs to individually check the work progress of the person in charge in the group, and meetings with the manager in another group often occur, so the leave time is generally longer than that of the person in charge. It tends to be long. In addition, the manager's seat is often placed in the perimeter side area, and most of the air conditioning space of the air conditioner is for the manager's seat, as opposed to the person's seat placed in the interior side area. Often there is. Here, the perimeter side area refers to an area on the outer peripheral side of the building that is relatively susceptible to changes in external conditions, and the air conditioning area 403B in FIG. 11 corresponds to the perimeter side area. The interior side area refers to an area inside the building that is relatively unaffected by changes in external conditions, and the air conditioning area 403A in FIG. 11 corresponds to the interior side area. That is, by operating the air conditioner in the interior area, it may be possible to sufficiently cover the air conditioning of the seat of the person in charge. Specifically, in the case of the configuration of FIG. 11, by operating the air conditioner 301A in the air conditioning area 403A, it may be possible to sufficiently cover the air conditioning of the six seats of the person in charge including the seats 404Ba and 404Bb. Based on the above contents, the method of air-conditioning operation control in consideration of the job title by the control device 111 will be described below.

FIG. 13 is a flowchart showing the operation of the air conditioning system of FIG. 11 by the control device. An air-conditioning operation control method when there is a distinction between managers will be described with reference to FIG. The same reference numerals are used for the same steps as in FIG. 7, and the description thereof will be omitted. By the way, FIG. 11 illustrates a case where one manager's seat is arranged in one air-conditioned area, but each of a plurality of managers' seats may be arranged in one air-conditioned area. , In the following, the latter case will also be assumed and described.

The calculation means 102 determines whether or not there is a manager's seat in each of the air-conditioned areas by the manager determination means 102m (step S301). When the calculation means 102 determines that there is no manager's seat (step S301 / No), the calculation means 102 proceeds to the process of step S101 of FIG. In the configuration of FIG. 11, since there is no manager's seat in the air-conditioned area 403A, the process proceeds to the process of step S101 of FIG.

On the other hand, when the calculation means 102 determines that there is an administrator's seat (step S301 / Yes), the administrator determination means 102m determines whether or not the administrator exists in the air-conditioned area where the administrator's seat is located. Determine (step S302). When the calculation means 102 determines that the administrator exists (step S302 / Yes), the calculation means 102 puts the air conditioner 301A into the operating state via the control means 103 (step S103).

On the other hand, when the calculation means 102 determines that the administrator does not exist in the air-conditioned area (step S302 / No), the presence / absence information of all the managers who have seats in the same air-conditioned area at the current time is obtained by the presence / absence determination means 102z. Determines whether or not indicates "absence" (step S303). The calculation means 102 causes the air conditioner 301A to execute the absentee operation when all the absentee information of all the managers indicates "absence" (step S105). When at least one of the presence / absence information of all the managers indicates "in-room", the calculation means 102 shifts to the process of step S103.

As described above, the air conditioning system 300 is designed to perform air conditioning operation control by distinguishing between the manager and the person in charge. Therefore, the chances of significantly stopping the operation of the air conditioner increase, and the power consumption during business hours can be reduced. The input person identification means 125Aa may be mounted only on the device control device of the administrator.

(Operation control of air conditioners considering individual entry and exit)
Further, since the air conditioning system 300 has the above-mentioned configuration, it is possible to realize the operation control of the air conditioner in consideration of the entrance and exit of an individual. For example, if an individual suddenly goes on a business trip or goes on vacation due to poor physical condition, that individual will be absent regardless of the information entered. However, according to the series of steps shown in the flowchart of FIG. 7 or 13, when the absence state indicates the presence of a room, the air conditioning operation of the air conditioner cannot be stopped. Therefore, the air conditioning system 300 is configured to correct the presence / absence information based on the entrance / exit information indicating the entrance / exit of each individual.

FIG. 14 is a flowchart showing the operation of the air conditioning system of FIG. 11 by the device control device. Based on FIG. 14, a method of determining the presence / absence state in consideration of the entry / exit of an individual by the device control device 121Aa will be described. The entry / exit reflection means 125m of the device control device 121Aa executes the following series of processes for each individual.

The entry / exit reflection means 125m determines whether or not an individual is entering (step S401). If the individual is entering the venue (step S401 / Yes), the entry / exit reflection means 125m is used as absence information corresponding to the schedule entered by the individual. That is, the entry / exit reflecting means 125m maintains the absence information set by the absence / absence information processing means 125y or the absence / absence information adjusted by the absence / absence information adjusting means 125z (step S402). On the other hand, if the individual has left the entrance / exit reflection means 125m (step S401 / No), the absence information on the day after the determined time is regarded as "absence equivalent" regardless of the schedule entered by the individual (step S401 / No). Step S403).

The series of processes of steps S401 to S403 returns to step S401 via step S402 or S403. Therefore, since the individual is not in the hall, even if the absence information is always "equivalent to absence", when the individual enters, it is possible to return to the absence information corresponding to the schedule entered by the individual. In addition, if an individual who is entering the venue leaves the venue during business hours, the absence information on the day after the exit time can be corrected to "equivalent to absence".

As described above, the air conditioning system 300 changes the absentee state according to the entry / exit situation of each individual. Therefore, the presence / absence determination means 102z of the calculation means 102 can perform the determination processing using the presence / absence information that more closely matches the current situation. Therefore, it is possible to increase the chances of stopping the air-conditioning operation of the air conditioner by reflecting the situation where the individual leaves the company unexpectedly, so that the power consumption can be reduced.

Embodiment 3.
FIG. 15 is a schematic view showing an example of the configuration of the air conditioning system according to the third embodiment of the present invention. FIG. 15 is an example of a view of the vertical surface of the installation space 403 from a certain point. In the air conditioning system 400 of the third embodiment, an air conditioner is installed in each seat. In FIG. 15, there are two sets of information devices in the installation space 403, seats, and individuals corresponding to the seats, and the area of the installation space 403 is divided into an air-conditioning area 403A and an air-conditioning area 403B. The division of the air-conditioned area is determined in the same manner as in the case of FIG. The same reference numerals are given to the configurations equivalent to those of the above-described first and second embodiments, and the parts different from those of the first and second embodiments will be described.

The air conditioner 301A is installed in the seat 404Aa, and the air conditioner 301B is installed in the seat 404Ba. In the installation space 403, an ambient air conditioner 405 that air-conditions the entire space is installed. That is, the air conditioning system 400 is configured such that the ambient air conditioner 405 performs overall air conditioning of the installation space 403, and the air conditioners 301A and 301B perform local air conditioning.

For example, in the situation as shown in FIG. 2 of the first embodiment or FIG. 11 of the second embodiment, when the individual 402Aa is hot and the individual 402Ab is cold, the air conditioner 301A has only one set temperature. Since not, one of the individuals will have an unpleasant temperature setting.

Therefore, the air conditioning system 400 adopts the above-mentioned configuration so that the ambient air conditioner 405 is always operated in air conditioning regardless of the absence information or schedule input. That is, the calculation means 102 controls the operation of the ambient air conditioner 405 via the control means 103. Further, for an individual who feels uncomfortable only by controlling the air conditioning of the ambient air conditioner 405, as in each of the above-described embodiments, the determination using the detection information by the personal position detecting means and the absence information based on the schedule input by the individual By the judgment using, additional air conditioning is performed. More specifically, the air conditioning system 400 executes the operations as shown in FIGS. 7 and 13 to operate the air conditioners 301A and 301B for task air conditioning.

Here, the air-conditioning set temperature of the ambient air conditioner 405 may be higher than the set temperatures of the air conditioners 301A and 301B during the cooling operation and lower than the set temperatures of the air conditioners 301A and 301B during the heating operation. For example, when a control for relaxing the set temperature is adopted as the absent operation of the air conditioner, the air conditioning set temperature of the ambient air conditioner 405 may be set to the set temperature during the absent operation. In this way, in the configuration of FIG. 15, when the set temperature of the air conditioners 301A and 301B is 26 ° C., the set temperature of the ambient air conditioner 405 can be adjusted to 28 ° C. Although the case where there are two seats is illustrated in FIG. 15, when the number of seats is different, the number of air conditioners is adjusted according to the number of seats. That is, if there are seven seats, seven air conditioners are installed corresponding to each seat.

Since the air conditioning system 400 of the third embodiment has an ambient air conditioner and an individually controllable air conditioner is arranged for each seat, it is possible to provide a comfortable space for each individual. can. Therefore, in the case of the configuration of FIG. 15, the comfort of both the individual 402Aa and the individual 402Ba can be enhanced. By the way, in the third embodiment, since the air conditioner is arranged near the seat, there is a concern that an individual's draft feeling may occur due to the air flow of the air conditioner. Therefore, it is preferable to provide the device control device with a wind direction air volume adjusting means for adjusting the wind direction or air volume of the air conditioner with respect to the position of the seat so that the individual can adjust the wind direction or air volume of the air conditioner while sitting on the seat. That is, by incorporating the wind direction / air volume adjusting means into the device control device, it is preferable that each individual can adjust the wind direction or the air volume of the air conditioner with respect to the position of the seat via the input device 42. By doing so, the airflow can be controlled according to each individual's preference, so that the draft feeling can be alleviated. Here, the configuration according to the modification of the first embodiment can be applied to the air conditioning system 400 of the third embodiment. Further, the air conditioning system 300 can also improve the accuracy of determining the presence or absence of a person and reduce the power consumption, as in the air conditioning system 100 of the first embodiment.
