Description

The present invention relates to an air conditioning control device, an air conditioning control system, and a control method capable of appropriately controlling an air conditioner after accurately grasping an application of an air conditioning area.

BACKGROUND ART Conventionally, for example, an air conditioning control system including a plurality of air conditioners has been installed in a building represented by an office building. With respect to such an air conditioning control system, various technologies have been proposed for improving user comfort and energy saving by controlling the air conditioner according to the condition of the air conditioning area where the air conditioner is in air conditioning.

For example, in Patent Document 1, a space in a building is divided into a plurality of areas (for example, an air conditioning area), and a processing load (a load for performing air conditioning) is applied to an air conditioner in an area where a user stays. An air conditioning control system is disclosed that increases the number of air conditioners while reducing the processing load on air conditioners in areas where the user is not staying. In addition, Patent Document 2 discloses an air conditioning control system that calculates an average staying time of users in each area and changes the setting of each air conditioner according to the amount of the average staying time.

In a building typified by an office building, each air-conditioned area is used for various purposes such as office work, meetings, and passages. However, in the conventional air conditioning control system, the usage of the air conditioning area cannot be accurately recognized, and the air conditioner may be inappropriately controlled.

For example, in the air conditioning control system of Patent Document 1 described above, the processing load is increased on the air conditioner in the air conditioning area in which the user is staying, but it is inappropriate when the air conditioning area is for passage use. Control. In other words, even if the processing load of the air conditioner is increased, the staying user will leave immediately, which does not lead to improvement in user comfort, and as a result, useless control (useless power consumption is being consumed). Control). On the other hand, in the air-conditioning control system of Patent Document 2 described above, since the average stay time is varied, useless control is not performed when the air-conditioning area is used for passages. Even so, if only the average stay time is used, it cannot be recognized whether the air-conditioning area is for office work or for meetings, and as a result, inappropriate control may be performed. In other words, when the air-conditioning area is used for meetings, it is often used intermittently (intermittently) unlike office work, and therefore control similar to office use causes waste.

The present invention has been made in order to solve the above problems, and an object of the present invention is to appropriately grasp the use of an air-conditioned area and appropriately control the air conditioner.

In order to achieve the above object, the air conditioning control device according to the present invention,
An air conditioning control device for controlling a plurality of air conditioners arranged in a building so as to have different air conditioning areas,
For each of the air-conditioning areas, a stay time calculating unit that calculates a total stay time indicating a cumulative stay time of the user and a representative stay time indicating a representative value of the stay time,
Application specifying means for specifying which of the at least three types of applications each of the air-conditioning areas is used for,
An air conditioner control unit that controls each of the air conditioners based on the total stay time for the corresponding air-conditioned area and the representative stay time ,
The use identifying means identifies the first use when the total staying time is larger than a first reference value and the representative staying time is larger than a second reference value, and the total staying time is determined. When the representative stay time is less than or equal to the first reference value and the representative stay time is greater than the second reference value, the second usage is specified, and the total stay time is less than or equal to the first reference value. And, if the representative staying time is less than or equal to the second reference value, it is specified as a third use,
The air conditioner control means specifies, for the air conditioner, the corresponding air conditioning area as the first application, as the second application, and as the third application. Different control is performed depending on the case.

According to the present invention, the stay time calculating means calculates the total stay time and the representative stay time for each of the air-conditioned areas. Then, the air conditioner control means controls each of the air conditioners based on the total stay time and the representative stay time. That is, the use of the air-conditioning area is clarified from the total stay time and the representative stay time, and control is performed according to the use, so that wasteful control of the air conditioner can be reduced. For example, when the total stay time is larger than the first reference value and the representative stay time is larger than the second reference value, the first use (as an example, office use) is specified, and the total stay time is specified. When the representative stay time is less than or equal to the first reference value and the representative stay time is greater than the second reference value, the second stay (as an example, meeting purpose) is identified, and the total stay time is less than or equal to the first finish value. And the representative stay time is equal to or less than the second reference value, the third use (as an example, a passage use) is specified. Then, the air conditioner control means performs different control depending on these first to third uses. As a result, it is possible to appropriately control the air conditioner after accurately grasping the use of the air conditioning area.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The same or corresponding parts in the drawings are designated by the same reference numerals. In the following, as a specific example, a case where the present invention is applied to an air conditioning control system installed in a building typified by an office building will be described. In addition to this, facilities (buildings used for exhibitions and attractions, etc. The present invention can be similarly applied to the air conditioning control system installed in (1). That is, the embodiments described below are for the purpose of explanation, and do not limit the scope of the present invention. Therefore, a person skilled in the art can adopt an embodiment in which each of these elements or all the elements are replaced by equivalents thereof, but these embodiments are also included in the scope of the present invention.

(Embodiment 1)
FIG. 1 is a block diagram showing an example of the overall configuration of an air conditioning control system 1 according to the first embodiment of the present invention. The air conditioning control system 1 is installed in, for example, a building typified by an office building, and as illustrated, a user terminal 2 (a plurality of user terminals 2 as an example), an air conditioning control device 3, and an air conditioner. 4 (for example, a plurality of air conditioners 4). The user terminal 2 and the air conditioning control device 3 are communicably connected via, for example, a wireless communication network WN. The air conditioning controller 3 and the air conditioner 4 are communicably connected via, for example, a wired air conditioning network AN.

In the building, the air conditioners 4 are arranged in the building such that the air conditioning areas are different. Below, as an example, the case where the space in the building is divided into 5 m-unit grids centering on each air conditioner 4 and each area is set as the air conditioning area of each air conditioner 4 will be described. The method of defining the air-conditioning area can be appropriately changed in addition to the division into such a grid pattern.

The user terminal 2 is a communication device carried (owned) by a user who uses the building in which the air conditioning control system 1 is installed. The user terminal 2 includes, for example, as shown in FIG. 2, a position information acquisition unit 21, a terminal ID storage unit 22, a terminal information creation unit 23, and a communication interface 24.

The position information acquisition unit 21 acquires position information indicating the current position of the user (user carrying the user terminal 2). For example, the position information acquisition unit 21 acquires position information using an indoor positioning technology (indoor GPS, as an example). In addition to this, the position information acquisition unit 21 may acquire position information using a camera or a thermal image measurement device. Further, the position information may be acquired by detecting the presence of a person using a personal computer, and further, the position information may be acquired by detecting the proximity of a short-range wireless communication or a beacon.

The terminal ID storage unit 22 stores a predefined terminal ID. For this terminal ID, for example, a serial number, a PIN number, and unique identification information represented by a MAC address are used.

The terminal information creation unit 23 generates terminal information including the position information acquired by the position information acquisition unit 21 and the terminal ID stored in the terminal ID storage unit 22. For example, the terminal information creation unit 23 periodically generates such terminal information (for example, every one minute).

The communication interface 24 is a communication device compatible with the communication network WN, and transmits the terminal information generated by the terminal information creation unit 23 to the air conditioning control device 3 via the communication network WN. For example, the communication interface 24 similarly transmits the terminal information to the air conditioning control device 3 periodically (for example, every one minute) in response to the terminal information creation unit 23 generating the terminal information.

Returning to FIG. 1, the air conditioning control device 3 is a home controller including, for example, a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), and controls the entire air conditioning control system 1. To do. The air conditioning control device 3, for example, as shown in FIG. 3, a communication interface 31, a terminal information acquisition unit 32, a terminal information holding unit 33, a stay time calculation unit 34 as a stay time calculation unit, and an application specifying unit. And an air conditioner control unit 36 as an air conditioner control unit, and an air conditioning communication interface 37. The stay time calculation unit 34, the use specification unit 35, and the air conditioner control unit 36 are realized by, for example, the CPU using the RAM as a work memory and executing various programs stored in the ROM as appropriate. It

The communication interface 31 is a communication device compatible with the communication network WN, and communicates with the user terminal 2.

The terminal information acquisition unit 32 acquires, via the communication interface 31, terminal information periodically sent from the user terminal 2. As described above, this terminal information includes the position information and the terminal ID.

The terminal information holding unit 33 holds the terminal information acquired by the terminal information acquisition unit 32. For example, the terminal information holding unit 33 has one holding area for each user terminal 2 and overwrites and stores new terminal information. As described above, since the terminal information is periodically sent from each user terminal 2, each terminal information is similarly updated to the terminal information holding unit 33 regularly (for example, every one minute). .. That is, the terminal information holding unit 33 holds the latest terminal information about each user terminal 2.

The stay time calculating unit 34 calculates, for each of the air-conditioning areas, a total stay time indicating a cumulative stay time of the user and a representative stay time indicating a representative value of the stay time. Hereinafter, the case where the representative stay time is calculated from the average value of the stay time will be described, but the representative stay time may be calculated from other values. For example, the stay time calculation unit 34 may calculate the representative stay time from the mode or the median of the stay times.

The usage identifying unit 35 identifies the usage of each air conditioning area based on the total stay time calculated by the stay time calculating unit 34 and the representative stay time. For example, the usage specifying unit 35 specifies the first usage (as an example, office usage) when the total stay time is larger than the first reference value and the representative stay time is larger than the second reference value. To do. In addition, the usage specifying unit 35 specifies the second usage (as an example, a meeting usage) when the total stay time is less than or equal to the first reference value and the representative stay time is greater than the second reference value. To do. Then, the usage specifying unit 35 specifies the third usage (as an example, a passage usage) when the total stay time is less than or equal to the first reference value and the representative stay time is less than or equal to the second reference value. To do.

The air conditioner control unit 36 controls each of the air conditioners 4 based on the total staying time and the representative staying time of the corresponding air conditioning area. That is, the air conditioner control unit 36 identifies the air-conditioning area based on the total stay time and the representative stay time as the first use, the second use, and the third use. Different control is performed on the air conditioner 4 depending on the situation. For example, the air conditioning control device 3 stores a control content determination table 361 as shown in FIG. Then, the air conditioner control unit 36 controls the air conditioner 4 according to the purpose of the air conditioning area based on the control content determination table 361.

For example, the air conditioner control unit 36 refers to the control content determination table 361, and when the air conditioning area is specified as the office use (first use), sets the temperature of the corresponding air conditioner 4 when the user is in the room. Is set to a reference temperature (as an example, 26° C. during cooling operation) and is not changed even when absent. In addition, when the air conditioning area is identified as the meeting use (second use), the air conditioner control unit 36 sets the temperature setting for the corresponding air conditioner 4 to the reference temperature when the user is in the room, while In the absence, the temperature setting is set to a reference temperature +1° C. (for example, 27° C. during cooling operation) to reduce the air conditioning load. Further, when the air-conditioning area is identified as the passage use (third use), the air-conditioner control unit 36 sets the temperature setting for the corresponding air-conditioner 4 to the reference temperature +1° C. when in the room. , The air conditioning load is reduced by not changing it even when there is no person.

In other words, the air-conditioned area where the representative stay time becomes large is for office work or meeting use, and is narrowed down to one of the uses based on the difference in total stay time (whether it is larger than the reference value or not). Then, the air conditioner control unit 36 immediately issues an instruction to the air conditioner 4 in the air conditioning area specified as the meeting purpose to reduce the air conditioning load when the user leaves the room (when the user is absent). Useless control can be reduced.

Further, although the air conditioner control unit 36 controls the air conditioner 4 in the air conditioning area specified as the office use to increase the air conditioning load when entering the room (when the user enters), the meeting use or the passage It is possible to reduce unnecessary control by not performing such control for the air conditioner 4 in the air conditioning area specified as the intended use.

Returning to FIG. 3, the air conditioning communication interface 37 is a communication device compatible with the air conditioning network AN, and communicates with the air conditioner 4. The air conditioner control unit 36 described above controls the air conditioner 4 through the air conditioning communication interface 37.

Returning to FIG. 1, the air conditioner 4 is controlled by the air conditioning control device 3 to perform air conditioning on the air conditioning area. As described above, the plurality of air conditioners 4 are installed so that the air conditioning areas are different in the building. Such an air conditioner 4 includes, for example, as shown in FIG. 5, an air conditioning communication interface 41, an air conditioning control unit 42, a control content holding unit 43, and an presence/absence detection unit 44.

The air conditioning communication interface 41 is a communication device compatible with the air conditioning network AN, and communicates with the air conditioning control device 3.

The air conditioning control unit 42 controls, for example, a refrigerant circuit that circulates a refrigerant between the outdoor unit and a fan that blows air. That is, the air conditioning control unit 42 controls the refrigerant circuit and the fan based on the command from the air conditioning control device 3 (information held in the control content holding unit 43) to perform air conditioning.

The control content holding unit 43 holds information about the control content sent from the air conditioning control device 3. For example, the control content holding unit 43 holds information about the set temperature and the set air volume.

The presence/absence detection unit 44 is, for example, a human sensor, and generates presence/absence information indicating whether or not the user is present in the air-conditioned area (own air-conditioned area). The presence/absence information also includes an air conditioner ID for identifying the air conditioner 4. The generated presence/absence information is sent to the air conditioning control device 3 through the air conditioning communication interface 41 periodically (for example, every one minute) (the same applies to the air conditioning control device 5 described later).

Hereinafter, the operation of the air conditioning control device 3 in the air conditioning control system 1 according to the first embodiment of the present invention will be described with reference to FIG. FIG. 6 is a flowchart showing an example of the control processing executed by the air conditioning control device 3. Note that this control process shows the flow of the entire process, and the details of each process will be described later. Further, this control process is started after a lapse of a certain period (one month as an example) after the operation of the air conditioning control system 1 is started.

First, the air conditioning control device 3 executes a total stay time calculation process (step S10). That is, the air conditioning control device 3 calculates the total stay time indicating the cumulative stay time of the user in each of the air-conditioned areas.

The air conditioning control device 3 executes a representative stay time calculation process (step S20). That is, the air conditioning control device 3 calculates a representative stay time indicating a representative value (for example, an average value) of the stay time in which the user stays in each of the air conditioning areas.

The air conditioning control device 3 executes an application specifying process (step S30). That is, the air conditioning control device 3 specifies the use of each air conditioning area based on the total stay time calculated in step S10 and the representative stay time calculated in step S20.

The air conditioning control device 3 executes an air conditioner control process (step S40). That is, the air conditioning control device 3 performs different control for each air conditioner 4 according to the use of each air conditioning area specified in step S30.

The details of each process in such a control process will be described below. First, details of the total stay time calculation processing in step S10 will be described with reference to FIG. More specifically, the total stay time calculation process of FIG. 7 is executed by the stay time calculator 34.

First, the stay time calculation unit 34 initializes the total stay time (step S101). That is, the stay time calculation unit 34 clears the value of the total stay time to zero.

The stay time calculation unit 34 performs the processes of steps S102 to S104 described below on each piece of terminal information held in the terminal information holding unit 33.

The stay time calculation unit 34 calculates the area number from the position information of the terminal information (step S102). For example, the air conditioning control device 3 stores, for each air conditioning area, a conversion table in which the range of the air conditioning area and the area number are associated with each other. The staying time calculating unit 34 refers to this conversion table to identify which air conditioning area the position information of the terminal information is within. Then, the stay time calculation unit 34 acquires the area number corresponding to the specified range of the air-conditioned area.

The stay time calculating unit 34 calculates the personal number from the terminal ID of the terminal information (step S103). For example, the air conditioning control device 3 stores a correspondence table in which each terminal ID is associated with a personal number. The stay time calculation unit 34 refers to this correspondence table and acquires the personal number corresponding to the terminal ID included in the terminal information.

The stay time calculation unit 34 adds the total stay time of the target (step S104). That is, the stay time calculation unit 34 adds 1 to the total stay time of the area number calculated in step S102.

When the process for all the terminal information is completed, the stay time calculation unit 34 ends the total stay time calculation process. Then, the process is returned to the control process of FIG.

Next, details of the representative stay time calculation process in step S20 of the control process of FIG. 6 will be described with reference to FIG. Specifically, the representative stay time calculation process of FIG. 8 is executed by the stay time calculator 34.

First, the stay time calculation unit 34 initializes the number of entrances and the previous area (step S201). That is, the stay time calculation unit 34 clears the number of entry times and the value of the previous area to zero.

The stay time calculation unit 34 performs the processes of steps S202 to S206 described below for each piece of terminal information held in the terminal information holding unit 33.

The stay time calculation unit 34 calculates the area number from the position information of the terminal information (step S202). The stay time calculating unit 34 calculates the personal number from the terminal ID of the terminal information (step S203).

The stay time calculation unit 34 determines whether the area number calculated in step S202 matches the previous area number (step S204). When the stay time calculating unit 34 determines that they match (step S204; Yes), the stay time calculating unit 34 proceeds to the processing of the next terminal information.

On the other hand, when it is determined that they do not match (step S204; No), the stay time calculation unit 34 adds the number of on-site visits (step S205). That is, the stay time calculation unit 34 adds 1 to the number of times of entry of the area number calculated in step S202.

The stay time calculation unit 34 updates the area number of the previous time (step S206). That is, the stay time calculating unit 34 sets the area number of this time to the area number of the previous time.

When the processing for all the terminal information is completed, the stay time calculation unit 34 divides the total stay time by the number of on-site visits (step S207). That is, the stay time calculation unit 34 calculates the average value of the stay times as the representative stay time. Note that, as described above, the stay time calculation unit 34 may calculate the representative stay time from, for example, the mode or the median of the stay times.

After calculating the representative stay time in this way, the stay time calculating unit 34 ends the representative stay time calculating process. Then, the process is returned to the control process of FIG.

Next, details of the use identifying process in step S30 of the control process of FIG. 6 will be described with reference to FIG. More specifically, the use identifying process of FIG. 9 is executed by the use identifying unit 35.

The usage identifying unit 35 performs the processes of steps S301 to S306 below for all areas (each air conditioning area).

The usage identifying unit 35 calculates the normalized total stay time from the total stay time (step S301). For example, the usage identifying unit 35 divides the total stay time of the target air-conditioned area by the total sum of the total stay time of the corresponding users, and calculates the stay time ratio for each user.

The usage identifying unit 35 determines whether or not the maximum value of the normalized total stay time is larger than a specified value (as an example, a first specified value) (step S302). For example, the usage identifying unit 35 determines whether the maximum value of the normalized total stay time is larger than 0.5.

When the usage specifying unit 35 determines that the maximum value of the normalized total stay time is larger than the specified value (step S302; Yes), the air conditioning area is specified as the office usage (step S303).

On the other hand, when it is determined that the maximum value of the normalized total stay time is not greater than (not more than) the specified value (step S302; No), the usage identifying unit 35 determines that the representative stay time is the specified value (as an example, It is determined whether or not it is larger than the second prescribed value) (step S304). For example, the usage identifying unit 35 determines whether the representative stay time is longer than 60 [minutes].

When determining that the representative staying time is longer than the specified value (step S304; Yes), the application identifying unit 35 identifies the air conditioning area as the meeting application (step S305).

On the other hand, when it is determined that the representative stay time is not larger than or equal to the prescribed value (the value is equal to or less than the specified value) (step S304; No), the usage identifying unit 35 identifies the air conditioning area as a passage usage (step S306).

When the processing for all areas is completed, the usage identifying unit 35 ends the usage identifying processing. Then, the process is returned to the control process of FIG.

Next, details of the air conditioner control process in step S40 of the control process of FIG. 6 will be described with reference to FIG. Specifically, the air conditioner control process of FIG. 10 is executed by the air conditioner control unit 36.

The air conditioner control unit 36 performs the processes of steps S401 to S403 described below for each air conditioner 4.

The air conditioner control unit 36 acquires the usage of the air conditioning area (step S401). That is, the air conditioner control unit 36 acquires the use of the air conditioning area (the air conditioning area of the target air conditioner 4) specified by the use specifying process of FIG. 9 described above.

The air conditioner control unit 36 acquires the control content corresponding to the application (step S402). For example, the air conditioner control unit 36 refers to the control content determination table 361 in FIG. 4 described above and acquires the control content corresponding to the application.

The air conditioner control unit 36 commands the air conditioner 4 to control the contents (step S403). That is, when the air-conditioning area is specified as the office use (first use), the meeting use (second use), and the passage use (third use) by the total stay time and the representative stay time. Different control is performed on the air conditioner 4 depending on the case of (application).

When the processing for all the air conditioners 4 is completed, the air conditioner control unit 36 ends the air conditioner control processing.

Through such processing, the air conditioning control device 3 calculates the total stay time and the representative stay time for each of the air conditioning areas. Then, the air conditioning control device 3 controls each of the air conditioners 4 based on the total stay time and the representative stay time. That is, the use of the air-conditioning area is clarified from the total stay time and the representative stay time, and control is performed according to the use, so that wasteful control of the air conditioner 4 can be reduced. For example, when the total stay time is larger than the first reference value and the representative stay time is larger than the second reference value, the first use (as an example, office use) is specified, and the total stay time is specified. When the representative stay time is less than or equal to the first reference value and the representative stay time is greater than the second reference value, the second stay (as an example, meeting purpose) is specified, and the total stay time is less than or equal to the first reference value. And the representative stay time is less than or equal to the second reference value, the third use (as an example, passage use) is specified. Then, the air conditioning control device 3 performs different controls according to these first to third uses. As a result, it is possible to appropriately control the air conditioner 4 after accurately grasping the use of the air conditioning area.

Further, the air conditioning controller 3 controls only the air conditioner 4 in the air conditioning area specified for the second application to reduce the air conditioning load within the specified time when the user no longer exists in that air conditioning area. Specifically, the air-conditioning area in which the representative stay time is large is for office use (first use) or meeting use (second use), and which is determined from the difference in total stay time (whether it is larger than the reference value or not). It is narrowed down to the use. Then, the air conditioning control device 3 immediately instructs the air conditioner 4 in the air conditioning area specified as the meeting purpose to reduce the air conditioning load when the user leaves the room (when the user is absent). It is possible to reduce unnecessary control.

Further, the air conditioning control device 3 controls only the air conditioner 4 in the air conditioning area specified for the first application to increase the air conditioning load within the specified time when the user comes from the air conditioning area. Specifically, the air conditioning control device 3 controls the air conditioner 4 in the air conditioning area specified as the office use (first use) to increase the air conditioning load when entering the room (when the user enters). Although it is performed, such control is not performed for the air conditioner 4 in the air conditioning area specified as the meeting use (second use) or the passage use (third use), thereby reducing unnecessary control. be able to.

(Embodiment 2)
In the first embodiment, the case where the air conditioner 4 is controlled based on the stay time of the user (total stay time and representative stay time) has been described. However, the air conditioner 4 is controlled based on the activity amount of the user. May be. The second embodiment of the present invention will be described below. In addition, also in the second embodiment, the entire configuration of the air conditioning control system 1 is the same as that in FIG. 1 described above. Nevertheless, as described below, the configurations of the user terminal 2 and the air conditioning control device 3 are slightly different from those of the first embodiment.

FIG. 11 is a schematic diagram illustrating an example of the configuration of the user terminal 2 according to the second embodiment. As shown in FIG. 11, the user terminal 2 includes a position information acquisition unit 21, a terminal ID storage unit 22, a terminal information creation unit 23, a communication interface 24, and a heartbeat information acquisition unit 25.

The position information acquisition unit 21 to the communication interface 24 are the same as the user terminal 2 of FIG. 2 described above. The differences in the terminal information creation unit 23 will be described later.

The heartbeat information acquisition unit 25 acquires heartbeat information (heartbeat rate, for example) of the user by using, for example, a heartbeat meter worn on the body surface of the user. It should be noted that this heartbeat information is acquired for use in obtaining the user's activity amount, and the user's activity amount may be obtained based on other information. For example, the user's body temperature information and acceleration information may be acquired to obtain the user's activity amount.

The terminal information creation unit 23 generates terminal information including the position information acquired by the position information acquisition unit 21, the heartbeat information acquired by the heartbeat information acquisition unit 25, and the terminal ID stored in the terminal ID storage unit 22. To do. For example, the terminal information creation unit 23 periodically generates such terminal information (for example, every one minute).

FIG. 12 is a schematic diagram illustrating an example of the configuration of the air conditioning control device 3 according to the second embodiment. As shown in the figure, the air conditioning control device 3 includes a communication interface 31, a terminal information acquisition unit 32, a terminal information holding unit 33, an activity amount calculation unit 38 as an activity amount calculation unit, and an application identification as an application identification unit. A unit 39, an air conditioner control unit 36 as an air conditioner control unit, and an air conditioning communication interface 37 are provided.

The communication interface 31 to the terminal information holding unit 33, the air conditioner control unit 36, and the air conditioning communication interface 37 are the same as those of the air conditioning control device 3 of FIG. 3 described above. The differences in the air conditioner control unit 36 will be described later.

The activity amount calculation unit 38 calculates, for each of the air-conditioned areas, a representative activity amount indicating a representative value of the user's activity amount during the stay. Hereinafter, a case where the representative activity amount is calculated from the average value of the heart rate will be described, but the representative activity amount may be calculated from other values. For example, the activity amount calculation unit 38 may calculate the representative activity amount from the mode and the median of the heart rate.

The use identifying unit 39 identifies each use of each air conditioning area based on the representative activity amount calculated by the activity amount calculating unit 38. For example, when the representative activity amount is larger than the third reference value, the use identifying unit 39 identifies the fourth use (for example, work use), while the representative activity amount is equal to or less than the third reference value. In some cases, it is specified as the fifth purpose (for example, work purpose).

The air conditioner control unit 36 controls each of the air conditioners 4 based on the representative activity amount for the corresponding air conditioning area. That is, the air conditioner control unit 36 differs for the air conditioner 4 depending on whether the air conditioning area is specified as the fourth application or the fifth application based on the representative activity amount. Take control. For example, the air conditioning control device 3 stores a control content determination table 362 as shown in FIG. Then, the air conditioner control unit 36 controls the air conditioner 4 according to the purpose of the air conditioning area based on the control content determination table 362.

For example, the air conditioner control unit 36 refers to the control content determination table 362, and when the air conditioning area is specified as the work purpose (fourth purpose), the temperature setting during cooling is set for the corresponding air conditioner 4. Is set to the reference temperature +1° C. (27° C. as an example), the temperature setting during heating is set to the reference temperature (20° C. as an example), and the air volume setting is set to a large value. In addition, the air conditioner control unit 36 sets the temperature setting during cooling/cooling to the reference temperature for the corresponding air conditioner 4 when the air conditioning area is identified as the non-work use (fifth use). At the same time, the air volume setting is set to medium.

In other words, the air-conditioned area in which the representative activity amount is large is for work purposes, and is in a state where the influence of the air flow on the user (discomfort) is small. Therefore, in the air-conditioned area for work, the sensible temperature of the user is lowered by increasing the air volume. In particular, during cooling, it is possible to improve comfort while reducing power consumption by increasing the air volume while increasing the temperature by 1° C. above the reference temperature.

Hereinafter, the operation of the air conditioning control device 3 in the air conditioning control system 1 according to the second embodiment of the present invention will be described with reference to FIG. FIG. 14 is a flowchart showing an example of the control process executed by the air conditioning control device 3. Note that this control process shows the flow of the entire process, and the details of each process will be described later. Further, this control process is started after a lapse of a certain period (one month as an example) after the operation of the air conditioning control system 1 is started.

First, the air conditioning control device 3 executes a representative activity amount calculation process (step S50). That is, the air conditioning control device 3 calculates the representative activity amount indicating the representative value of the activity amount of the user at the time of stay for each of the air conditioning areas.

The air conditioning control device 3 executes an application specifying process (step S60). That is, the air-conditioning control device 3 specifies each application of each air-conditioning area based on the representative activity amount calculated in step S50.

The air conditioning control device 3 executes an air conditioner control process (step S70). That is, the air conditioning control device 3 performs different control for each air conditioner 4 according to the use of each air conditioning area specified in step S60.

The details of each process in such a control process will be described below. First, details of the representative activity amount calculation process in step S50 will be described with reference to FIG. Specifically, the representative activity amount calculation process of FIG. 15 is executed by the activity amount calculation unit 38.

First, the activity amount calculation unit 38 initializes the cumulative activity amount and the number of elements (step S501). That is, the activity amount calculation unit 38 clears the values of the cumulative activity amount and the number of elements to zero.

The activity amount calculation unit 38 performs the processes of steps S502 to S505 described below on each piece of terminal information stored in the terminal information storage unit 33.

The activity amount calculation unit 38 calculates the area number from the position information of the terminal information (step S502). The activity amount calculation unit 38 calculates a personal number from the terminal ID of the terminal information (step S503).

The activity amount calculation unit 38 accumulates the heart rate of the terminal information (step S504). That is, the activity amount calculation unit 38 adds the heart rate to the cumulative activity amount of the area number calculated in step S502.

The activity amount calculation unit 38 adds the number of elements (step S505). That is, the activity amount calculation unit 38 adds 1 to the number of elements having the same area number.

When the processing for all the terminal information is completed, the activity amount calculation unit 38 divides the cumulative activity amount by the number of elements (step S506). That is, the activity amount calculation unit 38 calculates the average of the heart rate as the representative activity amount. Note that, as described above, the activity amount calculation unit 38 may calculate the representative activity amount from, for example, the mode value or the median value of the heart rate.

When the representative activity amount is calculated in this way, the activity amount calculation unit 38 ends the representative activity amount calculation process. Then, the process is returned to the control process of FIG.

Next, details of the use identifying process in step S60 of the control process of FIG. 14 will be described with reference to FIG. The application identifying process of FIG. 16 is executed by the application identifying unit 39 in detail.

The use identifying unit 39 performs the processes of steps S601 to S603 below for all areas (each air conditioning area).

The usage identifying unit 39 determines whether or not the representative activity amount is larger than a prescribed value (as an example, a third prescribed value) (step S601). For example, the usage identifying unit 39 determines whether the representative activity amount is larger than 100 [bpm].

When determining that the representative activity amount is larger than the specified value (step S601; Yes), the usage identifying unit 39 identifies the air conditioning area as a working application (step S602).

On the other hand, when it is determined that the representative activity amount is not greater than or equal to the specified value (the amount is equal to or less than the specified value) (step S601; No), the use identifying unit 39 identifies the air conditioning area as a non-work use (step S603).

When the processing for all areas is completed, the usage identifying unit 39 ends the usage identifying processing. Then, the process is returned to the control process of FIG.

Next, details of the air conditioner control process in step S70 of the control process of FIG. 14 will be described with reference to FIG. Specifically, the air conditioner control process of FIG. 17 is executed by the air conditioner control unit 36.

The air conditioner control unit 36 performs the processes of the following steps S701 to S703 for each air conditioner 4.

The air conditioner control unit 36 acquires the usage of the air conditioning area (step S701). That is, the air conditioner control unit 36 acquires the use of the air conditioning area (the air conditioning area of the target air conditioner 4) specified by the use specifying process of FIG. 16 described above.

The air conditioner control unit 36 acquires the control content corresponding to the application (step S702). For example, the air conditioner control unit 36 refers to the control content determination table 362 in FIG. 13 described above and acquires the control content corresponding to the application.

The air conditioner control unit 36 commands the air conditioner 4 to control the contents (step S703). That is, depending on whether the air-conditioning area is identified as the work use (fourth use) or the non-work use (fifth use) by the representative activity amount, Control differently.

When the processing for all the air conditioners 4 is completed, the air conditioner control unit 36 ends the air conditioner control processing.

Through such processing, the air conditioning control device 3 calculates the representative activity amount for each of the air conditioning areas. Then, the air conditioning control device 3 controls each of the air conditioners 4 based on the representative activity amount. That is, the use of the air-conditioning area becomes clear from the representative activity amount, and control is performed according to the use, so that useless control of the air conditioner 4 can be reduced. For example, when the representative activity amount is larger than the third reference value, the fourth use (as an example, work use) is specified, and when the representative activity amount is equal to or less than the third reference value, the fifth use ( As an example, non-work use) is specified. Then, the air conditioning control device 3 performs different controls according to these fourth and fifth uses. As a result, it is possible to appropriately control the air conditioner 4 after accurately grasping the use of the air conditioning area.

Further, the air conditioning control device 3 controls only the air conditioner 4 in the air conditioning area specified for the fourth application to increase the set temperature and increase the air volume during the cooling operation, and to increase the air volume during the heating operation. I do. That is, the air-conditioned area in which the representative activity amount is large is for work use (fourth use), and is in a state where the influence of the air flow on the user (discomfort) is small. Therefore, in the air-conditioned area for work, the sensible temperature of the user is lowered by increasing the air volume. In particular, during cooling, it is possible to improve comfort while reducing power consumption by increasing the air volume while increasing the temperature by 1° C. above the reference temperature.

The stay time calculation unit 54 determines whether or not the user exists based on the presence/absence information (step S112).

When the stay time calculation unit 54 determines that the user does not exist (step S112; No), the process proceeds to the next presence/absence information.

On the other hand, when it is determined that the user exists (step S112; Yes), the stay time calculation unit 54 calculates the area number from the air conditioner ID of the presence/absence information (step S113). For example, the air conditioning control device 5 stores a correspondence table in which each air conditioner ID is associated with an area number.

The stay time calculating unit 54 calculates the area number from the air conditioner ID of the presence/absence information (step S212). The stay time calculation unit 54 determines whether or not the user exists based on the presence/absence information (step S213).

When it is determined that the user exists (step S213; Yes), the stay time calculation unit 54 determines whether or not the user was absent last time (whether the presence/absence flag is off) (step S214). When the stay time calculating unit 54 determines that the user was not absent last time (step S214; No), the process proceeds to step S216 described below.

On the other hand, when it is determined that the user was absent last time (step S214; Yes), the stay time calculation unit 54 adds the number of on-site visits (step S215). That is, the stay time calculation unit 54 adds 1 to the number of times of entry of the area number calculated in step S212.

The stay time calculation unit 54 turns on the presence/absence flag (step S216).

When it is determined in step S213 described above that the user does not exist (step S213; No), the stay time calculation unit 54 turns off the presence flag (step S217).

When the processing for all the presence/absence information is completed, the stay time calculation unit 54 divides the total stay time by the number of on-site visits (step S218). That is, the stay time calculation unit 54 obtains the average value of the stay times as the representative stay time. Note that, as described above, the stay time calculating unit 54 may calculate the representative stay time from, for example, the mode or the median of the stay times.

After calculating the representative stay time in this way, the stay time calculating unit 54 ends the representative stay time calculating process. Then, the process is returned to the control process of FIG.

Next, details of the use identifying process in step S31 of the control process of FIG. 20 will be described with reference to FIG. The application identifying process of FIG. 23 is executed by the application identifying unit 55 in detail.

The usage identifying unit 55 performs the processing of steps S311 to S315 below for all areas (each air conditioning area).

The application identifying unit 55 determines whether or not the total stay time is larger than a specified value (for example, a fourth specified value) (step S311). For example, the usage identifying unit 55 determines whether the total staying time is longer than 50,000 [minutes].

When the usage specifying unit 55 determines that the total stay time is larger than the specified value (step S311; Yes), the usage specifying unit 55 specifies the air conditioning area as the office usage (step S312).

On the other hand, when it is determined that the total stay time is not greater than or equal to the specified value (is equal to or less than the specified value) (step S311; No), the usage identifying unit 55 determines that the representative stay time is the specified value (for example, the second specified value). ) Is larger than () (step S313). For example, the usage identifying unit 55 determines whether the representative stay time is longer than 60 [minutes].

When determining that the representative stay time is longer than the specified value (step S313; Yes), the application identifying unit 55 identifies the air conditioning area as the meeting application (step S314).

On the other hand, when it is determined that the representative staying time is not larger than or equal to the specified value (is equal to or less than the specified value) (step S313; No), the usage identifying unit 55 identifies the air conditioning area as a passage usage (step S315).

When the processing for all areas is completed, the usage identifying unit 55 ends the usage identifying processing. Then, the process is returned to the control process of FIG.

Through such processing, the air conditioning control device 5 calculates the total stay time and the representative stay time for each of the air conditioning areas. Then, the air conditioning control device 5 controls each of the air conditioners 4 based on the total stay time and the representative stay time. That is, the use of the air-conditioning area is clarified from the total stay time and the representative stay time, and control is performed according to the use, so that wasteful control of the air conditioner 4 can be reduced. For example, if the total stay time is larger than the fourth reference value and the representative stay time is larger than the second reference value, the first use (as an example, office use) is specified, and the total stay time is specified. When the representative stay time is less than or equal to the fourth reference value and the representative stay time is greater than the second reference value, the second stay (as an example, meeting purpose) is identified, and the total stay time is less than or equal to the fourth stay value. And the representative stay time is less than or equal to the second reference value, the third use (as an example, passage use) is specified. Then, the air conditioning control device 5 performs different control depending on these first to third uses. As a result, it is possible to appropriately control the air conditioner 4 after accurately grasping the use of the air conditioning area.
