Description

  The present invention relates to an air conditioning control device that centrally controls air conditioners (air conditioners) installed in a plurality of areas of a building.

  Air conditioning control is performed to control the operation of an air conditioner (air conditioner) installed in a conference room such as an office building in conjunction with a conference room usage reservation. For example, the air conditioner control device described in Patent Document 1 detects the use status of a conference room with a human body sensor, and when the conference room is not used without changing the schedule that was to use the conference room, Air conditioning in unused rooms is automatically stopped to reduce wasteful power consumption.

  The air conditioner control device of Patent Document 1 operates the air conditioner according to the schedule data and parameters, and simultaneously monitors the usage status of the control target section during the operation time with the human body sensor. And when the division is not used more than fixed time, an air conditioner is stopped. Even after stopping, the monitoring is continued with the human body sensor during the scheduled operation time of the schedule, and when the use of the section is confirmed, the air conditioner is started according to the schedule.

JP-A-5-248679

  However, since the air conditioner control device described in Patent Document 1 stops air conditioning only when it is not confirmed that there is a person in the conference room for a certain period of time after the scheduled start of use of the conference room, it reduces power consumption during that period. I can't. In order to identify whether there is a person in the room, it is necessary to newly provide a human body sensor. In a building having a plurality of conference rooms, there is a problem that the cost for installing and maintaining the human body sensor increases.

  The present invention has been made in view of the above circumstances, and an object thereof is to more efficiently reduce the power consumption of an air conditioner installed in a building.

  In order to solve the above-described problem, an air conditioning control device according to the present invention is a control unit that performs control including start and stop of operation of an air conditioner for each area of a building having a plurality of unit areas where the air conditioner is operated. And a presence information management unit that detects whether a worker working in the building enters and leaves the building and generates presence information indicating whether the worker is present or absent from the building for each worker. And a schedule management unit that manages schedule information including a scheduled start time and a scheduled end time of the worker using the area for at least one area. A control part controls the air conditioner of the area based on schedule information and presence information about at least one area.

  According to the present invention, in a building having a plurality of unit areas where the air conditioner is operated, when starting and stopping the operation of the air conditioner for each area, the presence information of workers working in the building, and Since the air conditioner in the area is controlled based on the schedule information of the worker using the area, the power consumption of the air conditioner installed in the building can be more efficiently reduced.

Embodiment 1 FIG.
FIG. 1 is a block diagram showing a configuration example of an air conditioning management system according to Embodiment 1 of the present invention. The air conditioning management system is installed in the building 1 including the areas 21 and 22. The air conditioning management system includes an air conditioning control device 10, air conditioner indoor units 31 and 32, remote controllers 41 and 42, an outdoor unit 5, a switching hub 6, a terminal 7, and a card reader 8. The air conditioning management system is installed inside the building 1 except for the outdoor unit 5. The indoor unit 31 and the remote controller 41 are installed in the area 21, and the indoor unit 32 and the remote controller 42 are installed in the area 22, respectively. Although only two areas 21 and 22 are shown in FIG. 1, the building 1 has two or more areas where an operator works.

  Areas 21 and 22 are units in which the air conditioner is operated. Areas 21 and 22 are places where air conditioning in the building is performed, such as office rooms, conference rooms, reception rooms, laboratories, processing sites, assembly sites, sorting / delivery workshops, and the like. The areas are not necessarily separated by walls. For example, the office room may be partitioned by a low partition, and an area where air conditioning is operated for each partitioned portion may be used. An area may also include two or more rooms. For example, in the case where air conditioning is controlled integrally like a studio room (demonstration room) and a monitor room, they can be regarded as one area. For example, area 21 is an office room and area 22 is a meeting room.

  The air conditioning control device 10 performs control including start and stop of the operation of the air conditioner for each of the areas 21 and 22 of the building 1. The air conditioning control device 10, the indoor units 31, 32, the remote controllers 41, 42, and the outdoor unit 5 are bus-connected by a dedicated line. The air conditioning control device 10, the terminal 7 and the card reader 8 are connected via a switching hub 6 via a LAN (Local Area Network). In FIG. 1, the terminal 7 is arranged in the area 21, but the position of the terminal 7 is not limited to one area 21. The terminal 7 may be movable by being connected by a wireless LAN, for example. The card reader 8 is installed at the entrance / exit of the building 1. Although one card reader 8 is shown in FIG. 1, one card reader 8 may be arranged inside and outside the entrance door.

  FIG. 2 is a block diagram illustrating a configuration example of the air conditioning control device according to the first embodiment. The air conditioning control device 10 includes a control unit 11, an input / output control unit 12, an input / output I / F 13, a LAN communication unit 14, a control signal communication unit 15, and a storage unit 16. The storage unit 16 stores schedule information 17, presence information 18 and setting information 19. The storage unit 16 may not store the setting information 19.

  The memory | storage part 16 is comprised by non-volatile memories, such as a hard disk, static RAM, or flash memory, for example. The input / output I / F 13 includes an input function and a display function such as a liquid crystal touch panel or a display and a keyboard.

  The LAN communication unit 14 transmits and receives information to and from the terminal 7 and the card reader 8 that are connected via the switching hub 6 via the LAN. The control signal communication unit 15 transmits and receives control signals to and from the indoor units 31 and 32, the remote controllers 41 and 42, and the outdoor unit 5 that are bus-connected by a dedicated line.

  The air-conditioning control apparatus 10 acquires the schedule information 17 including the scheduled start time and the scheduled end time of using the area 22 of the worker for at least one area, for example, the area 22 that is a conference room. The air-conditioning control device 10 detects entrance of the worker who works in the building 1 and exit from the building 1, and presence information indicating whether the worker is present or absent in the building 1 for each worker. 18 is generated. Then, the air conditioner 32 in the area 22 is controlled based on the schedule information 17 and the presence information 18 for at least one area 22.

  The worker of the building 1 registers the schedule information 17 including the scheduled start time and the scheduled end time of using the areas 21 and 22 in the air conditioning control device 10 using, for example, the terminal 7 or the input / output I / F 13. The schedule information 17 is data whose elements are the operator's name (identification code), the area to be used, the scheduled start time, and the scheduled end time. The input / output I / F 13, the LAN communication unit 14, the input / output control unit 12, the control unit 11, and the storage unit 16 of the air conditioning control device 10 constitute a schedule management unit.

  FIG. 3 is a diagram illustrating an example of schedule information according to the first embodiment. FIG. 3 shows that the workers “Taro Yamada” and “Ichiro Tanaka” use the conference room A from 9:00 to 10:00. The worker “Jiro Nakamura” is shown to use the conference room B from 10:30 to 12:00. Probably, the schedule which the other worker which is not illustrated uses B meeting room at the time which at least partially overlaps from 10:30 to 12:00 is registered.

  In the example of FIG. 3, “Taro Yamada” and “Ichiro Tanaka” use the A conference room in the same time zone, but the usage time zone of one area is scheduled to start for each worker who uses that area. Not all times from the time to the scheduled end time overlap. A certain worker may overlap in use time from the middle to the middle of another worker's use time.

  When an operator sets a schedule, each worker can input schedule data using the terminal 7. The schedule data input at the terminal 7 is transmitted to the LAN communication unit 14 of the air conditioning control device 10 via the LAN. The input / output control unit 12 sends the schedule data received by the LAN communication unit 14 to the control unit 11. Then, the control unit 11 generates schedule information from the received schedule data and stores it as the schedule information 17 in the storage unit 16. In other words, the air conditioning control device 10 acquires the schedule information 17 via the terminal 7 and the switching hub 6. When browsing the schedule information 17, the control unit 11 reads the schedule information 17 stored in the storage unit 16 and transmits it to the terminal 7 through the input / output control unit 12 and the LAN communication unit 14 via the LAN. The terminal 7 displays the received schedule information 17. The schedule information 17 can be input and viewed using the input / output I / F 13 of the air conditioning control device 10 without using the terminal 7 and the LAN.

  The worker stays in the building 1 until the worker enters the building 1 and then leaves, and the worker is absent from the building 1 until the worker leaves the building 1 and then enters again. In order to detect the entry / exit of the worker, for example, the following is performed. Unless the ID is read by the card reader 8, the door is prevented from opening. When the worker enters the building 1, for example, the operator holds the ID card he has on the card reader 8 outside the door and reads the ID. When leaving, the ID card is read by holding the ID card over the card reader 8 inside the door.

  Alternatively, an outer door and an inner door may be provided at the entrance and exit, and the card reader 8 may be disposed between them. When the outer door is opened and the card reader 8 reads the ID, the outer door is closed and the inner door is opened. When the inner door is opened and the card reader 8 reads the ID, the inner door is closed. If the outside door is opened, entrance / exit can be detected. In any case, the operator cannot enter or leave the building 1 unless the ID is read by holding the ID card over the card reader 8.

  The operator ID read by the card reader 8 and the entry / exit information are transmitted to the LAN communication unit 14 of the air-conditioning control apparatus 10 via the LAN, and to the control unit 11 via the input / output control unit 12. It is done. The control unit 11 generates presence information 18 indicating that the worker of the ID is present if the received data is entry, and is absent in the storage unit 16 and stores the presence information 18 in the storage unit 16. When browsing the presence information 18, the control unit 11 reads the presence information 18 stored in the storage unit 16, and transmits it to the terminal 7 via the LAN through the input / output control unit 12 and the LAN communication unit 14. To do. The terminal 7 displays the received presence information 18. The input / output I / F 13, the LAN communication unit 14, the input / output control unit 12, the control unit 11, and the storage unit 16 constitute a presence information management unit. The viewing of the presence information 18 can be performed using the input / output I / F 13 of the air conditioning control device 10 without using the terminal 7 and the LAN.

  FIG. 4 is a diagram illustrating an example of presence information according to the first embodiment. As shown in FIG. 4, the presence or absence of each worker is shown. For example, “Jiro Nakamura” is absent, and “Hanako Kimura” is present.

  In order to identify the worker and detect its entry / exit, it is not limited to the ID card and the card reader 8. For example, when entering or leaving, the worker may be authenticated by inputting an ID and password, or the worker may be authenticated using biometric information such as a fingerprint, glow, or vein. Or you may recognize an operator from the image of the face and attitude | position image | photographed with the camera.

  The air conditioning control device 10 controls the indoor unit 31, the indoor unit 32, and the outdoor unit 5 that are air conditioners through a dedicated bus. The control unit 11 refers to the schedule information 17 and the presence information 18 and performs control including operation start and operation stop of the air conditioner based on those information, and performs air conditioning in the areas 21 and 22.

  For example, in the case where any worker who overlaps the use time zone from the scheduled start time to the scheduled end time is present in the building 1 at the scheduled start time, the control unit 11 The operation of the air conditioner 32 is started, and the state of the air conditioner 32 in the area 22 is maintained when all workers having overlapping use time zones are absent from the building 1 at the scheduled start time.

  Here, the use time zone overlapping means that the use time zone overlaps continuously from the scheduled start time to the scheduled end time. The worker B whose scheduled start time of the area is set before the scheduled start time of a worker A and whose scheduled end time is set after the scheduled start time of the worker A is the scheduled start time of the worker A From the earlier to the end scheduled time, the worker A and the use time zone overlap. Each time the scheduled start time of the worker arrives for one area, the control unit 11 selects one of the workers in the building 1 at that time from among the workers whose use time zones starting from the scheduled start time overlap. If you are present, start the air conditioner in that area. In other words, the use time zone is divided for each scheduled start time and the scheduled end time, and it is checked whether the overlapping worker is present or absent in the building 1 for each scheduled start time, and any work in which the use time zone overlaps is checked. When the person is in the building 1 at the scheduled start time, the air conditioner in that area is started to operate. And when all the workers whose use time slot | zone overlaps in the building 1, the state of the air conditioner of the area is maintained.

  Here, starting the operation of the air conditioner includes continuing the operation when the air conditioner is in operation. Maintaining the state of the air conditioner means that the operation is continued if the air conditioner is in an operating state, and the stopped state is continued if it is in a stopped state.

  After starting the air conditioning operation in a certain area, the control unit 11 of the air conditioning control device 10 stops the operation of the air conditioner in that area at the last scheduled end time in the continuous work time zone of the area. In addition, after starting the operation of the air conditioner in a certain area, if all workers having overlapping usage time periods are absent from the building 1, the operation of the air conditioner in that area is stopped. Here, stopping the operation of the air conditioner includes continuing the stopped state as it is when the air conditioner is in the stopped state.

  For example, for a certain area, the same scheduled start time for workers A and C, scheduled start time for worker B, scheduled end time for worker A, scheduled end time for workers B and C, etc. It is assumed that there are no overlapping workers. The control unit 11 checks whether the workers A and C are both absent from the building 1 at the scheduled start time of the workers A and C. If the worker A or C is present in the building 1, Start operation of the air conditioner in the area. If the workers A and C are not in the building 1, the state of the air conditioner in the area is maintained. Next, when any of the workers A, B, and C is present in the building 1 at the scheduled start time of the worker B, the operation of the air conditioner in that area is started. If the operation has already started, the operation state is continued.

  Under the same assumption, the control unit 11 stops the operation of the air conditioner in the area at the same scheduled end time of the workers B and C, which is the final scheduled end time. If the workers A and C are both absent from the building 1 from the scheduled start time of the workers A and C to the scheduled start time of the worker B, the operation of the air conditioner in that area is stopped at that time. . If the workers A, B, and C are all absent from the building 1 from the scheduled start time of the worker B to the scheduled end time of the worker A, the operation of the air conditioner in that area is stopped at that time. . If both workers B and C are absent from the building 1 between the scheduled end time of the worker A and the scheduled end times of the workers B and C, the air conditioner in that area is operated at that time. Stop.

  FIG. 5 is a flowchart showing an example of the operation of the operation start control according to the first embodiment. The flowchart of FIG. 5 shows the operation of the operation start control of an air conditioner in one area of the building 1. The control unit 11 waits until the scheduled start time of the area arrives (step S10; N). When the scheduled start time is reached (step S10; Y), it is checked whether or not all workers having overlapping use time zones starting from the scheduled start time are absent in the building 1 (step S11). If any of the workers whose use time zones overlap is present in the building 1 (step S11; N), an operation start command is transmitted to the air conditioner in the area to start the operation (step S12). When all the workers whose usage time zones overlap are not present in the building 1 (step S11; Y), nothing is transmitted to the air conditioner in the area and the state is maintained.

  Here, it is assumed that the air conditioner does not change anything when it receives an operation start command in the operating state. For example, when the operation start command and the operation stop command are the same command code and the operation state and the stop state are switched every time they are received, step S12 checks the state of the air conditioner. Is broken down into an operation that nothing is transmitted in the operation state.

  FIG. 6 is a flowchart illustrating an example of the operation of the operation stop control according to the first embodiment. The flowchart of FIG. 6 shows the operation of the stop control of the air conditioner in a certain area of the building 1. The operation stop control is activated when the operation of the air conditioner in the area is started. The control unit 11 waits until the area becomes a use time zone (step S20; N). If the operation is started by the operation start control of FIG. 5, it is already in the use time zone. If it is a use time slot | zone (step S20; Y), the control part 11 will repeat all the work time slot | zones until it becomes the last scheduled end time in the continuous work time slot | zone of the area (step S21; N). It is checked whether the worker is absent from the building 1 (step S22). When all the workers are absent (step S22; Y), the operation of the air conditioner in the area is stopped (step S23). If no one is present (step S22; N), the process returns to step S21. When the last scheduled end time is reached in the continuous work time zone of the area (step S21; Y), the operation of the air conditioner in the area is stopped (step S23).

  Here, it is assumed that the air conditioner does not change when an operation stop command is further received when the air conditioner is stopped. For example, if the operation start command and the operation stop command are the same command code and the operation state and the stop state are switched every time they are received, step S23 checks the state of the air conditioner. Is stopped, and if stopped, nothing is transmitted.

  As described above, the air conditioning control device 10 according to the first embodiment is based on the presence information 18 of the worker who works in the building and the schedule information 17 that uses the area where the worker is located. To control. According to the air-conditioning control apparatus 10 of Embodiment 1, even if it does not detect whether there is an operator for each area of the building 1, it is installed in the building only by detecting entry / exit of the entire building 1 The power consumption of the air conditioner can be reduced more efficiently. The air conditioning control device 10 does not necessarily perform the control as described above for all the areas of the building 1. The above-described control is performed only in the target area where the schedule information 17 is generated.

  In the first embodiment, the presence information 18 at the scheduled start time is determined based only on the temporary point, but a grace period may be provided at the scheduled start time. For example, if there are no workers with overlapping usage hours at the scheduled start time, work that overlaps usage hours until the grace time elapses, instead of ending the start control without starting operation Wait for one of them to be present. For example, the grace time is stored in the setting information 19 of the storage unit 16.

  FIG. 7 is a flowchart illustrating an example of the operation of the start control when the grace time is included in the scheduled start time. The control unit 11 waits for the scheduled start time of the area to arrive (step S10; N). When the scheduled start time is reached (step S10; Y), one of the workers whose use time zones overlap is selected. If it is present in the building 1 (step S11; N), an operation start command is transmitted to the air conditioner in the area to start the operation (step S12). The process up to this point is the same as the flowchart of FIG.

  After reaching the scheduled start time (step S10; Y), if all workers with overlapping usage time zones are not in the building 1 (step S11; Y), use until the grace time elapses from the scheduled start time It is checked whether all workers with overlapping time zones are absent from the building 1 (step S13; N, step S11). Before any grace period elapses (step S13; N), if any of the workers whose usage time period overlaps is in the building 1 (step S11; N), an operation start command is sent to the air conditioner in that area. Is transmitted to start operation (step S12). When all the workers whose usage time period overlaps are not present in the building 1 (step S11; Y), when the grace period elapses (step S13; Y), the control unit 11 stops the operation of the air conditioner in the area. (Step S14). Step S12 for starting operation and step S14 for stopping operation are the same as those in FIGS. After the operation start control in FIG. 7, the operation stop control can be performed in the same manner as in FIG.

  According to the operation of FIG. 7, a grace period is provided at the scheduled start time, so that if any of the workers whose usage time period overlaps the grace time, the air conditioner in the area to be used is operated. The For example, it is possible to prevent the air conditioning in the area scheduled to be used from being started when all workers whose usage time zones temporarily overlap at the scheduled start time are outside the building 1. Moreover, since the operation of the air conditioner is stopped when all the workers having the same usage time period are absent even after the grace period elapses, power is not wasted.

  In the operation start control of FIG. 7, the grace time is arbitrary 0 or more. When the grace time is 0, the operation of the air conditioner in that area is stopped when all workers whose use time zones overlap at the scheduled start time are absent. This is a modification in which the operation of the air conditioner is stopped instead of maintaining the state of the air conditioner when no one is present in the operation of FIG. The grace time may be uniform in the building 1 regardless of the area, or may be changed for each area. For example, the grace time may be changed according to the number of workers using the area.

  Instead of starting the operation at the scheduled start time, the operation can also be started before the preliminary time of the scheduled start time. The reason why the operation is started before the preliminary time of the scheduled start time is to ensure that the room temperature of the planned use area reaches the set temperature at the scheduled start time. The operation performed before the scheduled start time is called preliminary operation. The spare time is stored in the setting information 19 of the storage unit 16, for example.

  FIG. 8 is a flowchart showing an example of the operation of the operation start control when the preliminary operation is performed before the scheduled start time. The control unit 11 waits for one zone before the preliminary time of the scheduled start time of the zone (step S30; N). When the preliminary time before the scheduled start time is reached (step S30; Y), it is checked whether all workers having overlapping use time zones starting from the scheduled start time are absent in the building 1 (step S31). When all workers with overlapping usage time zones are not present in the building 1 (step S31; Y), one of the workers with overlapping usage time zones is in the building until the scheduled start time (step S32; N). 1 (step S31; Y, step S32; N). If any of the workers whose use time zones overlap by the scheduled start time is in the building 1 (step S31; N), an operation start command is transmitted to the air conditioner in that area to start the operation. (Step S34).

  All workers whose usage time zones overlap are not present in the building 1 (step S31; Y), and when the scheduled start time is reached (step S32; Y), the usage time zones that start again from the scheduled start time are duplicated. It is checked whether all the persons are absent from the building 1 (step S33). If any of the workers whose use time zones overlap is present in the building 1 (step S33; N), an operation start command is transmitted to the air conditioner in the area to start the operation (step S34). When all the workers whose usage time zones overlap are not present in the building 1 (step S33; Y), nothing is transmitted to the air conditioner in the area and the state is maintained. About operation | movement start step S34, it is the same as that of FIG. After the operation start control in FIG. 8, the operation stop control can be performed in the same manner as in FIG.

  According to the operation of FIG. 8, if any worker whose usage time period starting from the scheduled start time overlaps before the scheduled start time before the scheduled start time is present in the building 1 Preliminary operation of air conditioners in the area. By performing the preliminary operation, the room temperature in the planned use area can be brought close to the set temperature at the scheduled start time. In addition, when all the workers whose usage times overlap in the spare time are not present in the building 1, the preliminary operation is not performed, so that power is not wasted.

  The spare time may be determined uniformly in the building 1 or may be changed for each area. Further, the preliminary time may be changed according to the season or the difference between the room temperature and the set temperature. For example, the reserve time may be increased if the difference between the room temperature and the set temperature is large, and the reserve time may be shortened if the difference is small.

  The grace time in FIG. 7 and the spare time in FIG. 8 can be provided together. In that case, for example, step S13 and step S14 in FIG. 7 may be connected to step S33 in FIG. Even in this case, after the operation start control, the operation stop control can be performed in the same manner as in FIG.

Embodiment 2. FIG.
FIG. 9 is a block diagram showing a configuration example of an air conditioning management system according to Embodiment 2 of the present invention. In the second embodiment, in the air conditioning management system, the air conditioner 32 in at least one area 22 is controlled based on the schedule information and presence information acquired by the air conditioning control device 10 via the switching hub 6. In the air conditioning management system of FIG. 9, in addition to the configuration of the first embodiment, a schedule management device 170 and an entrance / exit management device 180 are connected via a switching hub 6 via a LAN. Other configurations are the same as those of the first embodiment.

  In FIG. 9, the positions of the schedule management device 170 and the entrance / exit management device 180 are not defined. The positions of the schedule management device 170 and the entrance / exit management device 180 may be the area 21 or the area 22, or may be other areas where the worker cannot enter, for example. The positions of the schedule management device 170 and the entrance / exit management device 180 may be in the same area or in different areas, and the switching hub 6 is connected to a network (not shown), and other than the building 1. It may be an area.

  The worker of the building 1 schedules the schedule information 17b including the scheduled start time and the scheduled end time using the areas 21 and 22 by using, for example, an input / output I / F (not shown) of the terminal 7 or the schedule management device 170. Register in the management device 170. The LAN communication unit 14, the input / output control unit 12, the control unit 11, and the storage unit 16 of the air conditioning control device 10 constitute a schedule information acquisition unit. That is, the air conditioning control device 10 acquires the schedule information 17 b from the schedule management device 170 and stores it in the storage unit 16.

  The condition stored in the storage unit 16 may be configured so that the schedule management device 170 notifies the air conditioning control device 10 every time the schedule information 17b is changed, or the air conditioning control device 10 periodically downloads from the schedule management device 170. The structure to do may be sufficient. Further, the schedule information 17 may be acquired from the schedule management device 170 at a timing when the control unit 11 refers to the schedule information 17 without storing the schedule information 17 in the storage unit 16.

  The ID of the worker read by the card reader 8 and the entry / exit information are transmitted to the entrance / exit management device 180 via the LAN, and the entrance / exit management device 180 stores the ID of the received data if it is entered. Existence information 18b is generated in which the worker is present and absent if the worker is leaving. The LAN communication unit 14, the input / output control unit 12, the control unit 11, and the storage unit 16 of the air conditioning control device 10 constitute a presence information acquisition unit. That is, the air conditioning control device 10 acquires the presence information 18 b from the entrance / exit management device 180 and stores it in the storage unit 16.

  The condition stored in the storage unit 16 may be configured so that the entrance / exit management device 180 notifies the air conditioning control device 10 every time the presence information 18b is changed, or the air conditioning control device 10 periodically enters the entrance / exit management device. A configuration of downloading from 180 is also possible. The presence information 18 may not be stored in the storage unit 16 and may be acquired from the entrance / exit management device 180 at a timing when the control unit 11 refers to the presence information 18.

  In the air-conditioning control device 10 of the second embodiment, the configuration in which both the schedule information 17b and the presence information 18b are generated by devices other than the air-conditioning control device 10 has been described, but either the schedule information 17b or the presence information 18b It is good also as a structure which produces | generates only by apparatuses other than the air-conditioning control apparatus 10.

  According to the air-conditioning control device 10 of the second embodiment, by implementing the schedule management and entrance / exit management with a device different from the air-conditioning control, when replacing some of the devices, the other devices are used as they are. It is possible to easily expand and add the system.

Embodiment 3 FIG.
FIG. 10 is a block diagram illustrating a configuration example of an air conditioning management system according to Embodiment 3 of the present invention. In the third embodiment, in the air conditioning management system, a human body detection unit is provided in at least a part of the area of the building 1 to perform control including start and stop of air conditioning taking into account the obtained human body detection result. The air conditioning management system of FIG. 10 includes human body detection units 91 and 92 in addition to the configuration of the first embodiment. Other configurations are the same as those of the first embodiment.

  The area where the human body detection units 91 and 92 are provided in the third embodiment is included in the area where the air conditioning control according to the first embodiment is performed. In FIG. 10, one human body detection unit 91 and 92 is shown in each of the areas 21 and 22. The human body detection units 91 and 92 are not limited to one for each area. Two or more human body detection units may be provided according to the size of the area. When there are multiple human body detectors in one area, whether there are people in the area is determined by the logical sum of the multiple human body detectors if there are people, and the logical product if there are no people To do.

  The human body detection units 91 and 92 have an infrared sensor that can measure the temperature of the object in a non-contact manner, and detect whether or not a human body exists inside the room. The human body detection units 91 and 92 transmit the human body detection result to the air conditioning control device 10 via a dedicated line bus. The human body detection units 91 and 92 may be configured to be installed in the room separately from the indoor units 31 and 32, or may be configured to be integrated into the indoor units 31 and 32. Alternatively, a camera may be used as the human body detection units 91 and 92, and human body detection may be performed by analyzing an image captured by the camera. Note that the human body detection units 91 and 92 are connected to the air conditioning control device 10 via the switching hub 6 via a LAN, and the human body detection units 91 and 92 transmit the human body detection results to the air conditioning control device 10 via the LAN. Good. Further, as described in the second embodiment, either one or both of the schedule information and the presence information may be generated by a device other than the air conditioning control device 10.

  Whether the air-conditioning control apparatus 10 starts or stops the operation of the air conditioner in the area under a condition that combines the schedule information of the area, the presence information, and whether or not there is a person in the area. Or decide whether to keep the state. For example, in the operation start control of FIG. 5, in addition to whether or not all workers having the same usage time zone in the area are absent from the building 1, the operation of the air conditioner is started depending on whether or not the area is unattended. Or maintain the condition of the air conditioner.

  FIG. 11 is a flowchart illustrating an example of the operation of the operation start control according to the third embodiment. The operation is the same as that in FIG. 5 until step S41 for determining whether or not all workers having overlapping use time zones in the area are in the building 1 for the operation start control target area. When all the workers whose use time zones in the area overlap at the scheduled start time are not in the building 1 (step S41; Y), the state of the air conditioner in the area is maintained.

  When one of the workers whose usage time period overlaps is present in the building 1 (step S41; N), if there is a person in the area (if it is not unattended; step S42; N), the air conditioner in that area The operation start command is transmitted to and the operation is started (step S43). If the area is unattended (step S42; Y), nothing is transmitted to the air conditioner in the area and the state is maintained. About operation | movement start step S43, it is the same as that of FIG. After the operation start control in FIG. 11, the operation stop control can be performed in the same manner as in FIG.

  According to the operation start control of FIG. 11, even if any of the workers whose use time zones overlap is present in the building 1, the operation of the air conditioner is not started if the area is unattended. As a result, for example, when the area is not used without changing the schedule information for using the area, the operation of the air conditioner can be prevented from being started uselessly.

  FIG. 12 is a flowchart showing an example of the operation start control operation when the preliminary operation is performed before the scheduled start time. The operation of FIG. 12 is an example in which the human body detection result of the human body detection unit is combined with the operation start control of FIG. After the scheduled start time is reached (step S53; Y), until step S54, in which it is checked whether all the workers whose use time zones starting from the scheduled start time overlap are absent in the building 1, is shown in FIG. Same as operation. However, even if one of the workers whose usage hours overlap in the spare time starts operating the air conditioner in the presence, in order to determine whether there are people in that area after the scheduled start time, Step S52 is placed before the scheduled start time determination (step S53). When the scheduled start time is reached (step S53; Y), if all workers with overlapping usage time zones are absent from the building 1 (step S54; Y), nothing is sent to the air conditioners in that area. maintain.

  On the other hand, even if one of the workers whose usage hours overlap is present in the building 1 (step S54; N), if the area is unattended (step S55; Y), the air conditioner in that area The operation is stopped (step S58). Then, if any of the workers whose usage hours overlap is present in the building 1 (step S54; N), and there are people in the area (step S55; N), the air conditioner in the area starts operation. A command is transmitted to start operation (step S56). Steps S52 and S56 for starting operation and step S58 for stopping operation are the same as those in FIGS. After the operation start control in FIG. 12, the operation stop control can be performed in the same manner as in FIG.

  In the operation start control of FIG. 12, even when the operation start control including the preliminary operation is performed, the human body detection result of the area is used at the scheduled start time, and the operation of the air conditioner is stopped if the area is unattended. As a result, for example, when the area is not used without changing the schedule information for using the area, power is not wasted.

  FIG. 13 is a flowchart showing an example of the operation of the operation start control when a grace time is provided for the unmanned determination of the scheduled start time. The operation of FIG. 13 is an example in which a grace time is provided for the unattended determination of FIG. Steps up to step S55 in FIG. 13 are the same as steps up to step S55 in FIG. When the scheduled start time is reached (step S53; Y), if all workers with overlapping usage time zones are absent from the building 1 (step S54; Y), nothing is sent to the air conditioners in that area. maintain.

  After reaching the scheduled start time (step S53; Y), if any of the workers whose usage time zones overlap is present in the building 1 (step S54; Y), the grace time elapses from the scheduled start time. It is checked whether or not the area is unattended (step S55). If it is detected that there is a person in the area before the grace time elapses (step S57; N) (step S55; N), an operation start command is transmitted to the air conditioner in the area to start the operation ( Step S56). When the zone remains unattended (step S55; Y) and a grace period has elapsed (step S57; Y), the controller 11 stops the operation of the air conditioner in the zone (step S58). Step S56 for starting operation and step S58 for stopping operation are the same as those in FIGS. After the operation start control in FIG. 7, the operation stop control can be performed in the same manner as in FIG.

  In the operation start control of FIG. 13, the operation is not stopped if any of the workers appears in the area before the grace time elapses even after the scheduled start time. For example, it is possible to prevent the air-conditioning in the area scheduled to be used from being stopped when all workers whose usage time zones overlap are delayed from the scheduled start time. Moreover, since the operation of the air conditioner is stopped when the area is unattended even after the grace period has elapsed, power is not consumed unnecessarily.

  FIG. 14 is a flowchart illustrating an example of the operation of the operation stop control when the unattended determination is performed in the usage time period. The operation of FIG. 14 is an example in which the human body detection result of the human body detection unit is combined with the operation stop control of FIG. Steps up to step S62 in FIG. 14 are the same as steps up to step S22 in FIG. By the time when the last scheduled end time is reached (step S61; N), when all workers with overlapping use time zones are absent from the building 1 (step S62; Y), the air conditioner in that area is operated. Stop (step S65). Also, when the final scheduled end time is reached (step S61; Y), the operation of the air conditioner in that area is stopped (step S65).

  Even if any of the workers whose work time zones overlap is present in the building 1 (step S62; N) by the end scheduled end time (step S61; N), the area is If it is unattended (step S63; Y), it is observed whether or not the area is unattended (step S63; Y, step S64; N) until the reference time elapses after it has become unattended (step S64; N). If it is detected that there is a person before the reference time elapses after detecting that the person is unattended (step S64; N, step S63; N), the process returns to step S61 and reaches the last scheduled end time. The determination of the absence of all persons and the absence of the area is repeated until it becomes (step S62, step S63). When the reference time has passed with the area left unattended (step S64; Y), the operation of the air conditioner in the area is stopped (step S65). The operation stop step S65 is the same as in FIG.

  According to the operation stop control of FIG. 14, even when the air conditioner in a certain area is not stopped and the area becomes unattended, the air conditioner can be stopped within the reference time, so that power is wasted. Can be prevented.

  According to the air conditioning control device of the third embodiment, by performing determination using the human body detection result, it is possible to automatically perform control such that air conditioning is not performed when there is no person in the target area, thereby further reducing power consumption. Reduction is possible.

Embodiment 4 FIG.
The air conditioning control device of the fourth embodiment controls the operation of the air conditioner in the area using the set temperature of the air conditioning in the area. For example, the set temperature of the area is changed according to the number of workers having overlapping use time zones in the area, and the set temperature is commanded to the air conditioner in the area. The set temperature of the zone is stored as part of the setting information 19 in the storage unit 16 of the air conditioning control device 10.

  FIG. 15 is a diagram showing an example of setting information according to Embodiment 4 of the present invention. In the example of FIG. 15, the set temperature and the reference number of persons are determined for each area where the worker sets the scheduled start time and the scheduled end time based on at least schedule information. The set temperature may be the same in all areas or may be different for each area. The set temperature may be determined for each season. Alternatively, it may be determined according to the outside air temperature.

  The control unit 11 of the air-conditioning control apparatus 10 refers to the schedule information 17 and totals the number of simultaneous users at one time in a certain usage time zone, and the number of simultaneous users exceeds the reference number of people in FIG. If so, the set temperature of the area is lowered by a predetermined value, and the air conditioner in the area is commanded.

  FIG. 16 is a flowchart showing an example of operation control operation according to the fourth embodiment. The control unit 11 waits for a certain area until the usage time zone of the area is reached (step S70; N). When the usage time zone of the area is reached (step S70; Y), the number of workers whose usage time zones of the area overlap is counted (step S71). Then, with reference to the set temperature and the standard number of people in the area, when the number of simultaneous users in the area exceeds the standard number of people (step S72; Y), the set temperature is lowered by a predetermined value, The changed set temperature is commanded to the air conditioner (step S73). If the simultaneous use number does not exceed the reference number (step S72; N), the set temperature of the air conditioner is not changed.

  Until the scheduled end time, it is checked whether there is a change in the planned number of workers in the schedule information 17 (step S74; N, step S75; N). If there is a change in the planned number of workers (step S74; Y), step S71 is performed. Return to and repeat from the simultaneous user count. The scheduled number of workers changes when the scheduled start time or scheduled end time is set up to the last scheduled end time in the usage time period.

  When the scheduled end time is reached (step S75; Y), the control unit 11 returns to step S70 and waits until the next use time zone is reached. The operation start is performed by, for example, the operation start control in FIGS. 5, 7, 8, or 11 to 13. Then, the operation stop is performed by the operation stop control of FIG. 6 or FIG. 14, for example.

  In addition, when the number of simultaneous users does not exceed the reference number in step S72 of FIG. 16, the referred set temperature may be instructed to the air conditioner as it is. Even if the number of simultaneous users exceeds the reference number of people and the set temperature is lowered, even if the number of simultaneous users falls below the reference number of people, the set temperature can be properly restored to reduce power consumption.

  FIG. 17 is a diagram illustrating an example of setting information when the reference population density is included. In order to control the temperature of a certain area, the set temperature may be changed according to the population density of the area. In the example of FIG. 17, the set temperature, area, and reference population density are determined for each area. These data are stored as a part of the setting information 19 in the storage unit 16 of the air conditioning control device 10 as in FIG. The reference population density may be determined according to the volume of the area, for example, a room.

  The control unit 11 of the air-conditioning control device 10 refers to the schedule information 17 and totals the number of simultaneous users in one usage time zone for one area, and refers to the “area” in FIG. Calculate the density. When the population density of the area exceeds the reference population density of FIG. 17, the set temperature of the area is lowered by a predetermined value, and the air conditioner of the area is commanded.

  FIG. 18 is a flowchart showing an example of operation control operation when the temperature is set based on the population density of the area. The control unit 11 waits for a certain area until the usage time zone of the area is reached (step S80; N). When the usage time zone of the area is reached (step S80; Y), the number of workers whose usage time zones of the area overlap is totaled, and the population density is calculated with reference to the area size (step S81). ). Then, with reference to the set temperature and the standard population density of the area, when the population density of the area exceeds the standard population density (step S82; Y), the set temperature is lowered by a predetermined value, and the area The changed set temperature is commanded to the air conditioner (step S83). If the population density of the area does not exceed the reference population density (step S82; N), the set temperature of the air conditioner is not changed.

  Until the scheduled end time, it is checked whether there is a change in the planned number of workers in the schedule information 17 (step S84; N, step S85; N). If there is a change in the planned number of workers (step S84; Y), step S81 is performed. Return to and repeat from the population density calculation. When the scheduled end time is reached (step S85; Y), the process returns to step S80 and waits until the next use time zone is reached. Also in this case, the operation start is performed by, for example, the operation start control of FIG. 5, FIG. 7, FIG. 8, or FIGS. 11 to 13, and the operation stop is performed by, for example, the operation stop control of FIG.

  In addition, when the population density does not exceed the reference population density in step S82 in FIG. 18, the referred set temperature may be commanded to the air conditioner as it is. Even when the population density falls below the reference population density after the population density exceeds the reference population density and the set temperature is lowered, the set temperature can be appropriately restored to reduce power consumption.

  If there are many people in the area, the room temperature tends to rise. According to the air conditioning control device of the fourth embodiment, when the number of simultaneous users exceeds the reference number of people, or when the population density exceeds the reference population density, the set temperature is adjusted downward to perform air conditioning. If it is, operation at a more comfortable temperature is possible, and if heating is used, operation with reduced power consumption is possible.

  In the example of the schedule information shown in FIG. 3, the worker, the area to be used, the scheduled start time, and the scheduled end time are set. You may add the preset temperature of the area used for schedule information. In that case, the air conditioner is operated at a specified set temperature during the use time period.

  FIG. 19 is a flowchart showing an example of operation of operation start control for instructing temperature at the start of operation. FIG. 19 shows an operation in which a temperature command is added to the operation start control of FIG. Steps S90 to S92 are the same as steps S10 to S12 in FIG.

  If any of the workers whose usage time zones overlap is present in the building 1 (step S91; N) at the scheduled start time of the area (step S90; Y), the controller 11 performs air conditioning in the area. An operation start command is transmitted to the machine to start the operation (step S92), and the temperature command is given to the air conditioner at the set temperature with reference to the set temperature of the schedule information 17 (step S93). If all workers with overlapping usage time zones are not present in the building 1 (step S91; Y), nothing is transmitted to the air conditioners in the area and the state is maintained.

  According to the operation start control of FIG. 19, when starting the operation of the air conditioner, it is possible to operate at the set temperature set in the schedule information 17. It is possible to add not only the temperature but also other setting parameters such as humidity and wind speed to the schedule information 17. This makes it possible to simultaneously set the air conditioning when registering the schedule.
