The control system 10 is, for example, a HEMS (Home Energy Management System) that manages energy such as electric power in a house. In HEMS, for example, one or more HEMS devices (air conditioners 300a, 300b, blower mechanism 210, etc.) in a house are connected to a HEMS controller (control device) via a HAN (Home Area Network) in order to reduce power consumption. 100) control. In HEMS, the state of power supply and demand by the HEMS device can be measured, and the state of power supply and demand in the house can be displayed on a monitor, a tablet (not shown) or the like based on the measurement result. Moreover, in HEMS, information, such as preset temperature of the air conditioners 300a and 300b, can be displayed on a monitor etc., for example. Hereinafter, the control system 10 will be described with attention paid to control of air blowing and the like for adjusting (making comfortable) the thermal environment in the house.

  FIG. 1 shows a state in which the air blowing mechanism 210 blows air from the air outlets 210a to 210c to form a curtain made of air. FIG. 1 shows that the air conditioner 300a keeps the temperature of the kitchen area 20a at about 25 ° C., and the air conditioner 300b keeps the temperature of the living area 20b at about 28 ° C. The curtain by air exhibits the function of the curtain as a partition on the surface separating the thermal environment, but has no light shielding function because the air is colorless and transparent. Thereby, it is possible to see each other between the users who sandwich the curtain made of air.

  The control device 100 can communicate with the air conditioners 300a and 300b, the blower mechanism 210, and the wireless devices 90a and 90b via a HAN in a wired or wireless manner, and has a function of controlling the blown air in the blower mechanism 210. The control device 100 is a computer that includes a memory, a communication circuit, and a CPU (Central Processing Unit) and can function as a HEMS controller.

This control circuit is a circuit that controls to send air (air, airflow) from the air outlets 210a to 210c with a specified air volume. In this control, for example, the number of rotations of the fan per unit time is determined in advance corresponding to each of the plurality of air volumes, and the number of rotations of the fan is selected according to the designated air volume and becomes the number of rotations. It is executed by rotating the fan. The air volume is expressed as a level such as “strong”, “medium”, and “weak”, or a value that takes a unit such as a numerical level or cubic meter per hour. For example, the fan speed corresponding to “strong” as the air volume is higher than the fan speed corresponding to “medium”, and the fan speed corresponding to “medium” is the fan speed corresponding to “weak”. It is higher than the rotation speed. The air volume from the blower mechanism 210 is controlled by changing the wind speed according to the number of rotations of the fan, for example, by changing the opening area of the air outlet or the opening of a valve provided in the air duct. Is also possible.

To do.

(Operation)
Hereinafter, an operation example of the control system 10 having the above-described configuration will be described focusing on the operation of the control device 100.

  FIG. 6 is a flowchart illustrating an example of control processing in the control device 100. Hereinafter, the control process will be described with reference to FIG.

  The control apparatus 100 determines whether different users are present in the first area and the second area using the result of specifying the user position by the user authentication unit 120 (step S11). Here, the first area and the second area are a kitchen area 20a and a living area 20b, respectively. When it is determined in step S11 that different users are present in the first area and the second area, the control device 100 determines whether or not the state has continued for a certain time (for example, several minutes). It discriminate | determines (step S12). If the state where separate users are located in the first area and the second area does not continue for a certain period of time, the control device 100 does not start special control such as blowing. Thereby, for example, when the user is moving between the first area or the second area and the outside thereof, the control is not started.

  When the state where different users are located in the first area and the second area continues for a certain period of time, the processing after step S13 is started.

  That is, when it is determined in step S <b> 12 that the control apparatus 100 has continued for a certain period of time, the control device 100 performs the first area and the second region by the acquisition unit 130 based on the user information of each user authenticated (identified) by the user authentication unit 120. Temperature information indicating each set temperature of the area is acquired (step S13).

  Subsequently, the control unit 140 of the control device 100 transmits the set temperature of the first region to the air conditioner 300a and transmits the set temperature of the second region to the air conditioner 300b based on the temperature information acquired in step S13. Thus, each air conditioner is controlled (step S14). Correspondingly, the air conditioner 300a and the air conditioner 300b each perform control such as cooling and heating so that the received set temperature is set as a target temperature. Note that before the control in step S14, the air conditioner 300a and the air conditioner 300b may or may not be operating with a certain temperature as a target.

  For example, when the user identified by the user identifier “A” is located in the first area (kitchen area 20a) and the user identified by the user identifier “B” is located in the second area (living area 20b) Assuming the user information having the contents illustrated in FIG. That is, the target temperature for air conditioning of the air conditioner 300a is 25 ° C., and the target temperature for air conditioning of the air conditioner 300b is 28 ° C.

  Next, the control unit 140 selects the air volume of the air to be sent out by the blower mechanism 210 based on the air volume information according to the difference between the set temperatures of the first area and the second area (step S15). When there is no temperature difference (when the temperature difference is zero), zero is selected as the air volume. Assuming the air volume information illustrated in FIG. 5, for example, when the temperature difference is 3 ° C., “medium” is selected as the air volume. As the temperature difference is larger, the air volume of the air sent out by the blower mechanism 210 is increased, whereby the thermal environment between the first region and the second region can be appropriately separated. Moreover, in order to isolate | separate each thermal environment of a 1st area | region and a 2nd area | region, the air volume of air is enough, so that the temperature difference of both area | regions is small. For this reason, when the temperature difference is small, for example, the rotational speed of the fan in the air blowing mechanism 210 is relatively low, so that waste of energy required for the rotation of the fan is suppressed, and generation of useless vibration, sound, etc. is suppressed. Can be done.

  When the selected air volume is not zero (that is, the temperature difference is not zero) (step S16), the control unit 140 controls the air blowing mechanism 210 to blow with the selected air volume (step S17). In addition, when the selected air volume is zero, the control unit 140 skips step S17 and does not control the air blowing mechanism 210, that is, does not operate the air blowing mechanism 210, and suppresses unnecessary air blowing.

  In this way, the control system 10 causes the air blowing mechanism 210 to blow out air of an appropriate air volume from the air outlets 210a to 210c to form a curtain made of air, so that the kitchen area 20a and the living area 20b have different temperatures. I can keep it.

(Embodiment 2)

  FIG. 8 is a functional block diagram of the control system 11. FIG. 8 shows main components for realizing control (control of the air blowing mechanism 220 and the like) for preparing a thermal environment in a house room.

  The control system 11 includes a control device 100a, air conditioners 300a and 300b, a blower mechanism 220, and a user interface device 91. The same components as those of the control system 10 among the components of the control system 11 are denoted by the same reference numerals, and description thereof is omitted here.

  The control device 100a is a computer similar to the control device 100 in terms of hardware.

Unit 110a, acquisition unit 130a, and control unit 140a.

  The storage unit 110a is realized in one area of the memory and has a function of storing the air volume information (see FIG. 5) shown in the first embodiment.

  The acquisition unit 130a receives, from the user interface device 91, position information for specifying a boundary position between the first area and the second area in the house room, and a temperature indicating a set temperature that is a target for temperature adjustment in each area. It has a function of acquiring information and transmitting it to the control unit 140a. The acquisition unit 130a is realized by a communication circuit, a CPU that executes a program, and the like.

  The control unit 140a has a function of controlling the blower mechanism 220 based on the position information and temperature information transmitted from the acquisition unit 130a, and controlling the air conditioners 300a and 300b based on the temperature information. The control unit 140a is realized by a communication circuit, a CPU that executes a program, and the like. About control of the ventilation mechanism 220, the control part 140a specifies the air blower outlet which should blow off air based on position information, and selects the air volume of the air blown out based on temperature information and air volume information. The control unit 140a controls the blower mechanism 220 by transmitting a signal specifying the specified air outlet and the selected air volume to the control circuit in the blower mechanism 220. The designation of the air outlet is performed, for example, by designation of an identification number predetermined for each air outlet.

  The user interface device 91 is a tablet, a smartphone, or the like, and is a device that displays information and receives an input from a user (resident of a house). The user interface device 91 includes, for example, a display device such as a display and a projector, an input device such as a touch panel, a pointing device, and a keyboard, a memory, a communication circuit, and a CPU. Note that the user interface device 91 can function as a device for displaying the state of power supply and demand in, for example, HEMS.

  FIG. 9 shows an input screen 410 of the user interface device 91. As shown in the figure, on the input screen 410, a display object 411 representing the entire area of the house room is displayed, and the room is divided into a first area (first space) and a second area (second space). A finger-shaped pointer (cursor) 412 for pointing to the position is displayed. The input screen 410 includes an input field 413a for inputting the set temperature of the first area (first space) and an input field 413b for inputting the set temperature of the second area (second space). . The user can specify a boundary position between the first area and the second area by moving the finger pointer by operating the input device. Further, the user can designate the set temperatures of the first region and the second region by inputting into the input fields 413a and 413b by operating the input device. The user interface device 91 has a function of notifying the control device 100a that an input has been made when an input is made by the user. The user interface device 91 also includes position information for specifying the boundary position between the first area and the second area in accordance with the operation of the input screen 410 by the user, and temperature information indicating the set temperature for each area. Are generated and transmitted to the control device 100a. The notification that there is an input from the user interface device 91 to the control device 100a, the notification of the position information, and the notification of the temperature information may be collectively performed.

(Operation)
Hereinafter, an operation example of the control system 11 having the above-described configuration will be described focusing on the operation of the control device 100a. Here, it is assumed that the air conditioner 300a is installed on the first area side and the air conditioner 300b is installed on the second area side in the house room.

  FIG. 10 is a flowchart illustrating an example of a control process in the control device 100a. Hereinafter, the control process will be described with reference to FIG.

  When the user interface device 91 receives an input by the user, the control device 100a receives a notification that the input by the user has been made (step S21), and acquires temperature information from the user interface device 91 (step S22). For example, it is assumed that an input as illustrated in FIG. 9 is made on the input screen 410 of the user interface device 91 by the user. In this case, the temperature information acquired from the user interface device 91 by the control device 100a indicates 25 ° C. as the set temperature of the first space and 28 ° C. as the set temperature of the second space.

  The control unit 140a of the control device 100a controls each air conditioner by transmitting the set temperature of the first area to the air conditioner 300a based on the acquired temperature information and transmitting the set temperature of the second area to the air conditioner 300b. (Step S23). Correspondingly, the air conditioner 300a and the air conditioner 300b each perform control such as cooling and heating so that the received set temperature is set as a target temperature.

  Further, the control unit 140a should acquire position information indicating the boundary position between the first area and the second area designated by the user from the user interface device 91, and air blowing should be performed based on the position information. An air outlet in the blower mechanism 220 is specified (step S24). For example, the control device 100a identifies each air outlet by an identification number, stores each installation position in advance, and causes the user interface device 91 to display an image drawn by associating the installation position with a certain coordinate space. The position information indicating the boundary position in the coordinate space is acquired. Thereby, based on position information, the air blower outlet (air blower outlet in a fixed short distance, such as within 0.3 meters from a boundary line) along the boundary line shown by the boundary position is specified.

  Subsequently, the control unit 140a selects the air volume of the air to be sent out by the blower mechanism 220 based on the difference between the set temperatures of the first area and the second area and the air volume information (step S25). When there is no temperature difference (when the temperature difference is zero), zero is selected as the air volume.

  When the selected air volume is not zero (that is, the temperature difference is not zero) (step S26), the controller 140a causes the air blowing mechanism 220 to blow with the air volume selected in step S25 from the air outlet specified in step S24. Control (step S27). For example, the control unit 140a performs control by transmitting information indicating the identification number of the air outlet and the air volume. As a result, the air blowing mechanism 220 separates the thermal environment of the first region and the second region at a position according to the user's input, and the air curtain is sent so as to send the air amount of air necessary for the separation. Form.

  If the selected air volume is zero in step S26, the control unit 140a skips step S27 and does not control the air blowing mechanism 220, that is, does not operate the air blowing mechanism 220, and suppresses unnecessary air blowing. To do.

  In this way, in the control system 11, since the air blowing mechanism 220 blows out air with an appropriate air volume from a part of the air outlets to form a curtain with air, the user has different thermal environments in the room of the house. , It can be separated into a plurality of regions of any size.

  The storage unit 110b is realized in one area of the memory and has a function of storing the air volume information (see FIG. 5) shown in the first embodiment.

  The acquisition unit 130b has a function of acquiring temperature information indicating a set temperature set (stored) in the air conditioner 300a and 300b and transmitting the temperature information to the control unit 140b. Further, the acquisition unit 130b receives an image (image data) from the imaging device 92, acquires position information indicating the position of the boundary that separates the user's location under a certain condition from the image, and transmits the position information to the control unit 140b. It has a function. The acquisition unit 130b detects the user's location by image processing, and when the two users are separated by a distance indicated by a predetermined threshold and do not move for a certain time (for example, several minutes). Position information indicating the position of the boundary that separates the two person's location areas is calculated. The distance indicated by this threshold is 3 meters, for example. Moreover, the boundary which isolate | separates each person's location area is the 1st area | region side (right side of FIG. 7) in which the air conditioner 300a is installed in the room of a residence, and the 2nd area | region side in which the air conditioner 300b is installed (Left side in FIG. 7) is separated at a position between two persons.

  The control unit 140b has a function of controlling the blower mechanism 220 based on the position information and temperature information transmitted from the acquisition unit 130b. The control unit 140b is realized by a communication circuit, a CPU that executes a program, and the like. About control of the ventilation mechanism 220, the control part 140b specifies the air blower outlet which should blow off air based on position information similarly to the control part 140a shown in Embodiment 2, and uses temperature information and air volume information. The air volume to be blown out is selected based on this.

(Operation)
Hereinafter, an operation example of the control system 12 having the above-described configuration will be described focusing on the operation of the control device 100b.

  FIG. 12 is a flowchart illustrating an example of a control process in the control device 100b. Hereinafter, the control process will be described with reference to FIG.

  Whether or not the control unit 100b is in a state where the two users do not move for a certain period of time and are not less than the distance indicated by the threshold based on the images sequentially transmitted from the imaging device 92 by the acquisition unit 130b. Is discriminated (step S31).

  When it is determined that the two users do not move for a certain period of time and are not less than the distance indicated by the threshold, the control device 100b determines the position of the boundary that separates the first area and the second area from the position of each user. The air outlet is specified by calculating so as to be between the users (step S32). For example, the acquisition unit 130b calculates a position between the users (for example, the center between two people) as a boundary position, and transmits position information indicating the position of the boundary to the control unit 140b. The control unit 140b identifies an air outlet (an air outlet located within a certain short distance such as within 0.3 meters from the boundary line on the ceiling) along the boundary indicated by the position information.

  The acquisition unit 130b acquires temperature information by receiving set temperatures from the air conditioner 300a installed on the first area side and the air conditioner 300b installed on the second area side, and acquires the temperature information. Information is transmitted to the controller 140b (step S33).

  The control unit 140b determines the air volume to be sent by the blower mechanism 220 based on the air volume information according to the difference between the set temperatures of the air conditioner 300a and the air conditioner 300b indicated by the temperature information from the acquisition unit 130b. Select (step S34). For example, assuming that the air volume information illustrated in FIG. 5 is used, when the set temperatures set by the user in the air conditioners 300a and 300b are 25 ° C. and 28 ° C., respectively, the temperature difference is 3 ° C. “Medium” is selected as the air volume. When there is no temperature difference (when the temperature difference is zero), zero is selected as the air volume.

  When the selected air volume is not zero (that is, the temperature difference is not zero) (step S35), the controller 140b causes the air blowing mechanism 220 to blow with the air volume selected in step S34 from the air outlet specified in step S32. Control is performed (step S36). For example, the control unit 140b performs control by transmitting information indicating the identification number of the identified air outlet and the air volume. As a result, the air blowing mechanism 220 separates the thermal environment between the first region and the second region at a position corresponding to the location of each of the two users, and sends out air with an amount of air necessary for the separation. Form a curtain with air.

  If the selected air volume is zero in step S35, the controller 140b skips step S36 and controls the air blowing mechanism 220 to stop the air blowing (step S37). It should be noted that no special processing is performed when the blowing of the blowing mechanism 220 has already stopped in step S37.

  In addition, when it is determined in step S31 that the two users do not move for a certain period of time and are not separated by the distance indicated by the threshold, the control unit 140b stops the blowing of the blowing mechanism 220. Control is performed (step S37). For this reason, in the state where the user is moving or not far away from the threshold distance, the blowing by the blowing mechanism 220 is stopped.

  After controlling the air blowing mechanism 220 in steps S36 and S37, the process from step S31 is repeated again in the control device 100b. In step S36, when it is not necessary to change from the state in which the blower mechanism 220 is already controlled, the control unit 140b of the control device 100b omits transmission of information indicating the identification number of the air outlet and the air volume. Can do. When the user changes the set temperature of the air conditioners 300a and 300b by repeating such processing, the control device 100b selects the air volume and controls the blower mechanism 220 correspondingly, and the blower mechanism 220 blows air. The air volume of the air can be changed.

  As described above, in the control system 12, in a situation where two users work in different places in the same room, a curtain with air of an appropriate amount of airflow is formed to separate the thermal environment of each user's location. can do. Further, for example, in a scene where the users are close together and performing joint work together, the blowing is stopped so as not to disturb the joint work.

(Other embodiments, etc.)
As mentioned above, although control system 10-12 was demonstrated by Embodiment 1-3, it cannot be overemphasized that embodiment mentioned above is only an example and various changes, addition, omission, etc. are possible.

  In Embodiment 1, user authentication is performed by receiving a signal wirelessly transmitted from the wearable sensor by a wireless device, and an area where the user is located is detected. Instead of the wearable sensor, a portable terminal such as a smartphone that transmits a terminal identifier (terminal ID) by wireless communication may be used. Further, the location of the user may be detected by an RF tag (for example, an active tag) possessed by the user using RFID (Radio Frequency Identifier) technology. In the third embodiment, the location of the user is detected from the image. However, any method may be used to detect the location of the user. For example, a plurality of human sensors (infrared sensors, etc.) May be arranged in the room to detect the position of the user in the room.

  In the above-described embodiment, the air conditioner is shown. However, the air conditioner is merely an example of an apparatus that can adjust the temperature (air temperature) of the space. For example, a heater or the like may be used instead of the air conditioner. . Moreover, it is good also as a ventilation mechanism adjusting the temperature of space by blowing out the air which adjusted temperature from the air blower outlet instead of an air conditioner (blowing air of preset temperature). Further, the control system may not include a device that can adjust the temperature, such as an air conditioner. However, when the user uses a device that can adjust the temperature, a heat source, or other object outside the control system that cannot communicate with the control device of the control system, the set temperature described above is determined by the user. Temperature or temperature measured from around the user. That is, the set temperature is not necessarily set (stored) in a device such as an air conditioner as long as it is a temperature that is to be maintained (that is, a temperature that is a target for temperature adjustment) in a thermal environment that is separated by blowing air from a blowing mechanism. Need not be at a certain temperature. In the control system, the air volume of air sent out by the blower mechanism is controlled based on the difference in the set temperature for each region.

  In the above-described embodiment, the control devices 100, 100a, and 100b control the blower mechanism by transmitting a signal to the control circuit of the blower mechanism. However, the control devices 100, 100a, and 100b are controlled by the blower mechanism. It is also possible to assume the function of the control circuit. Moreover, you may change how the function sharing of each function part in the control apparatuses 100-100b changes. Further, even when the control devices 100, 100a, and 100b communicate with an external device (such as a server) of the control system, the external device may execute a part of the processing contents described above in the control devices 100, 100a, and 100b. Good.

  Further, in the above-described third embodiment, the case where there are two users is described as an example of freely dividing the space, but a space such as a house room is divided into a plurality of regions even if there are three or more users. Can be divided into For example, two or more corresponding to three or more people so that one or more users are located in each divided area and each user in one area is separated from each user in another area by a certain distance It can be divided into three or more regions. In this case, the control device controls the air blowing mechanism including a plurality of air outlets so as to select and blow the air outlet along the boundary between the divided areas. In the first embodiment described above, an example in which the first region and the second region do not change and the boundary position between both regions does not change is shown. In the second and third embodiments, the first region and the second region Although the example in which the position of the boundary of can be changed has been shown, the same applies to the case where the boundary is divided into three or more regions. That is, when dividing into three or more areas, the position of the boundary between the areas may be fixed or may change.

  In the above-described embodiment, the control device selects the air volume (the air volume to be sent to the blower mechanism) based on the temperature information indicating the set temperature for each region that is the thermal environment to be separated. In addition to this, for example, in addition to the temperature information, the control device may select the air volume based on humidity information indicating a condition regarding humidity for each region (that is, set humidity that is humidity to be held). . In this case, the control device can use, for example, the air volume information illustrated in FIG. 13 instead of the air volume information illustrated in FIG. The air volume information shown in FIG. 13 is information in which an air volume is associated with a set of a temperature difference between areas indicated by temperature information and a humidity difference between areas indicated by humidity information. For a given number of temperature and humidity differences, if the temperature difference is the same, the larger the humidity difference, the more air volume is associated. If the humidity difference is the same, the larger the temperature difference is, the more air volume is associated. It has been. The example of FIG. 13 is an example corresponding to a blower mechanism that can control the air volume at a numerical level, and the larger the air volume value, the greater the air volume. The control process in which the control device in the example in which the control system is modified to use the air volume information shown in FIG. 13 controls the blower mechanism has the contents shown in the flowchart of FIG. 14, for example. In the figure, the air conditioners 300a and 300b are installed apart from each other in a residential room. The area on the air conditioner 300a side is the first area, the area on the air conditioner 300b side is the second area, and the first area and the second area are An example is assumed in which the space is separated as a thermal environment by sending air by a blower mechanism. First, the control device acquires temperature information indicating set temperatures and humidity information indicating set humidity of the air conditioners 300a and 300b in the first region and the second region, respectively, by an acquisition unit (for example, the acquisition units 130, 130a, and 130b). (Step S41). For example, the control device acquires the temperature information and the humidity information by receiving the set temperature and the set humidity from each air conditioner or receiving the set temperature and the set humidity input by the user. Subsequently, the control device is controlled by the control unit (for example, the control units 140, 140a, 140b, etc.) based on the air volume information (FIG. 13) according to the set temperature difference and the set humidity difference between the first area and the second area. The air volume to be sent out by the blower mechanism is selected (step S42). When there is no temperature difference, zero is selected as the air volume. Based on the air volume information illustrated in FIG. 13, for example, when the temperature difference is 4 ° C. and the humidity difference is 20%, “4” is selected as the air volume level. If the air volume is not zero (step S43), the control device controls the air blowing mechanism to blow with the air volume selected by the control unit (step S44). Each air conditioner 300a, 300b performs air conditioning so as to have a set temperature and set humidity. Thereby, a curtain is formed by the air of an appropriate amount of air sent out by the blower mechanism, and the room of the house is separated into thermal environments having different temperatures and humidity.

  Further, the control units 140, 140a, and 140b shown in the above-described embodiment select the air volume according to the difference between the two set temperatures based on the air volume information that associates the temperature difference and the air volume for each of the plurality of air volumes. However, such air volume information is not necessarily used. For example, a predetermined calculation or algorithm for specifying the air volume from the temperature difference may be used. The air volume information may be determined based on research, theory, or the like, or air volume information in which an appropriate air volume is associated with the temperature difference may be determined by performing an experiment for each air blowing mechanism.

  In addition, the control system shown in the above-described embodiment is for controlling the air blowing by the air blowing mechanism in the facility. In the above-described embodiment, the room of a house is shown as an example of the facility. For example, it may be a factory, a building, a stadium, a hall, a station building, or the like. In addition, the control system does not necessarily have a function related to energy supply and demand (function as HEMS), that is, the control system may not be HEMS.

  In the above-described embodiment, as an example of the blower mechanism, the blower mechanisms 210 and 220 that can change a plurality of airflows other than zero are illustrated, but the blower mechanism can be changed between zero airflow and other than zero airflow. There may be ones that cannot change a plurality of airflows other than zero. The air blowing mechanism may have only one air outlet. Moreover, the ventilation mechanism should just be able to ventilate so that a thermal environment can be isolate | separated, and even if it is a single-piece | unit apparatus (product), it may be comprised as a collection of various apparatuses or members, for example, Even an air curtain may be configured as a part of the entire building air-conditioning ventilation system.

  In the above-described embodiment, as an example of the air blowing mechanism, the air blowing mechanism 220 that can change the delivery position of air (air, airflow) by selection from a plurality of air outlets is shown. The direction in which air blows out from the outlet may be changeable, for example, by changing the angle of the slats. In this case, in the control system, for example, in order to change the boundary position that separates one space of the facility into two regions, the direction in which the air in the blower mechanism blows out may be controlled.

  Moreover, in the control system 10 shown in the above-mentioned Embodiment 1, it is good also as controlling the ventilation mechanism 220 which can change the direction or position which sends out the ventilation mechanism 220 or air instead of the ventilation mechanism 210. FIG. In this case, the control unit 140 of the control device 100 changes the direction in which air is sent or the position to send air by the blower mechanism according to the location of each user specified by the user authentication unit 120, and It is good also as controlling so that air is sent out between. Further, the user authentication unit 120 may be added to the control system 12 of the third embodiment. The control system 12 uses the user authentication unit 120 to identify each user located in the room of the house, identify the location, and use the preset temperature and the like registered in advance for each user. By determining the set temperature of the air conditioner in the area, the air conditioner can be controlled.

  In the above-described embodiment, as an example of one condition for causing the air blowing mechanism to blow air (sending air with an air volume larger than zero) in the control system, in addition to the temperature difference, (a) the same space (room, etc.) That there are multiple users (steps S11 and S31), (b) that there is no change in the position of the users (steps S12 and S31), and (c) that the users are separated by a certain distance or more (step S31). It was. Any method may be used to determine whether or not each of these conditions is satisfied. Further, all or a part of these conditions may be used. Further, as a specific example of the condition (b) that there is no change in the position of the user, the change in the location of each user per predetermined unit time (for example, several tens of seconds, several minutes, etc.) 1 meter, several meters, etc.). For example, the user authentication unit 120 in the control system 10 may determine whether or not the position change is smaller than a predetermined reference in step S12. A specific example of the condition (c) that the users are separated by a certain distance or more is that the distance between the two users exceeds a certain threshold (for example, 1 meter, several meters, etc.).

  Further, the execution order of the above-described control processing procedure (see FIGS. 6, 10, 12, and 14) is not necessarily limited to the order as described above, and does not depart from the gist of the invention. The execution order can be changed or a part thereof can be omitted. Further, all or part of the above-described control processing procedure may be realized by hardware of the control devices 100 to 100b or other devices, or may be realized by using software. The processing by software is realized by a CPU (processor) included in the control devices 100 to 100b or other devices executing a control program stored in the memory. Further, the program may be recorded on a recording medium and distributed or distributed. For example, by installing the distributed control program in the apparatus and causing the CPU (processor) of the apparatus to execute it, it is possible to cause the apparatus to perform all or part of the control processing.

  In addition, embodiments realized by arbitrarily combining the constituent elements and functions described in the above-described embodiments are also included in the scope of the present invention.

  Note that various general or specific aspects of the present invention include one or a plurality of combinations of an apparatus, a system, a method, an integrated circuit, a computer program, a computer-readable recording medium, and the like.

  Hereinafter, a control system according to an aspect of the present invention, and a configuration, a modification, an effect, and the like of a control device and a control program related to the control system will be described.

  (1) A control system according to an aspect of the present invention is a control system 10 (or control system 11, 12 or the like) that controls ventilation by a blowing mechanism in a facility (for example, a room in a house), An acquisition unit 130 (or acquisition units 130a and 130b) that acquires temperature information indicating a set temperature that is a target of temperature adjustment in each of the first region and the second region, and each of the first region and the second region indicated by the temperature information Between the first region and the second region by the blower mechanism 210 (or the blower mechanism 220) in accordance with the temperature difference between the set temperatures (that is, the difference between the set temperature of the first region and the set temperature of the second region). The control part 140 (or control part 140a, 140b) which performs control which concerns on the air volume of the airflow (air) sent out to is provided.

  With this configuration, since the space in the facility can be separated into a plurality of regions as a thermal environment, it is possible to increase the possibility of comforting each of a plurality of persons having different requirements for the thermal environment in the facility.

  (2) For example, the air blowing mechanisms 210 and 220 have a function of blowing air with a selected air volume among a plurality of air volumes, and the control units 140, 140a, and 140b are predetermined values that associate a temperature difference with each of the air volumes. Referring to the air volume information, the air volume is selected according to the temperature difference between the set temperatures of the first area and the second area, and the air blowing mechanisms 210 and 220 are controlled so as to send out the air flow with the selected air volume. It is good.

  Thereby, separation of the space in the facility into a plurality of regions in terms of the thermal environment can be realized by blowing an appropriate amount of airflow based on a predetermined relationship between the temperature difference and the airflow.

  (3) For example, the control system 10 further includes, for a plurality of users, a storage unit 110 that stores user information indicating a set temperature for each user and authentication information for each user, and a facility with reference to the authentication information. A user authentication unit 120 that identifies two or more users located within the user authentication unit 120, and the acquisition unit 130 specifies a set temperature of each of the users identified by the user authentication unit 120 based on the user information. Information may be acquired.

  Thereby, since each user is identified by the user authentication unit 120 and the preset temperature that has already been stored is used, for example, the user can control the ventilation as in the control system 11 described in the second embodiment. There is no need to enter the set temperature.

  (4) For example, the user authentication unit 120 identifies two or more users located in the facility and identifies the location of each user, and the control units 140 and 140b are identified by the user authentication unit 120. Depending on the location of each user, it may be possible to perform control related to the direction in which the airflow is sent out by the blower mechanisms 210 and 220 or the position where the airflow is sent out.

  Thereby, according to the position of each user, airflow can be sent out along the boundary which isolate | separates space into a some area | region, for example so that users may be separated.

  (5) For example, the user authentication unit 120 identifies two or more users located in the facility and repeatedly specifies the location of each user, and the control units 140 and 140b When it is determined that the change in the location of the user is smaller than a predetermined reference, the air volume may be controlled to be greater than zero.

  As a result, air is blown on the condition that the user is not moving (that is, when the user is staying and it is assumed that there is a high need to separate the thermal environment so that the set temperature can be maintained). become.

  (6) For example, the air volume information is information in which a larger air temperature is associated with a larger temperature difference, and the control units 140, 140a, and 140b are set temperatures of the first area and the second area indicated by the temperature information, respectively. A larger air volume may be selected as the temperature difference between them is larger.

  As a result, an appropriate amount of air is blown according to the conditions of the thermal environment of each region to be separated. As the temperature difference is smaller, for example, the rotational speed of the fan in the blower mechanism 210 is relatively low, and unnecessary power consumption can be suppressed, and generation of vibration, sound, and the like can be suppressed.

  (7) For example, the acquisition units 130a and 130b acquire position information for specifying the boundary position between the first region and the second region, and the control units 140a and 140b can generate a blower mechanism according to the position information. It is good also as performing the control which concerns on the direction which sends out airflow by 220, or the position which sends out airflow.

  As a result, the position of the airflow (air) to be blown is controlled, and the boundary position for separating the space as a thermal environment can be changed. Further, for example, the user can designate the position of the airflow to be blown by giving the position information to the control system.

  (8) For example, the control unit 140b determines whether or not the distance between two users located in the facility exceeds a certain threshold, and the air volume that is blown only when it is determined that the distance exceeds the certain threshold. Control may be performed so as to be larger than zero.

  Thereby, since ventilation is not performed when the distance between users is near a fixed threshold value, it is suppressed that ventilation interferes with collaborative work in a scene where the users are working together.

  (9) For example, the air blowing mechanism is an air curtain that blows out air from a plurality of air outlets.

  Thereby, since the row | line | column with which the air which blows off by an air blower outlet can be formed, the thermal environment of space can be isolate | separated appropriately by the row | line | column with which the air continued.

  (10) For example, the acquisition unit 130b may acquire temperature information from the air conditioners 300a and 300b installed in the facility.

  Thereby, the area | region where each air conditioner adjusts temperature separately by the ventilation of the appropriate air volume according to the difference of the setting temperature of each air conditioner can be isolate | separated.

  (11) For example, the acquisition units 130, 130a, and 130b may further acquire humidity information related to the humidity in the facility, and the control units 140, 140a, and 140b may perform control related to the air volume according to the humidity information. Good.

  Thereby, in order to isolate | separate one space of a facility into the several thermal environment from which temperature and humidity differ, ventilation of an appropriate air volume comes to be made | formed.

  (12) A control method according to an aspect of the present invention is a control method for controlling air blowing by a blower mechanism (for example, a blower mechanism 210, 220) in a facility (for example, a room of a house). An acquisition step (for example, steps S13, S22, S33, etc.) for acquiring temperature information indicating a set temperature that is a target for temperature adjustment in each of the first region and the second region, and each of the first region and the second region indicated by the temperature information And a control step (for example, steps S17, S27, S36, etc.) for performing control related to the air volume of the air flow sent out by the blower mechanism between the first region and the second region according to the temperature difference between the set temperatures. .

  As a result, the space in the facility can be separated into a plurality of regions having a difference in temperature by the control of the air blowing mechanism, so that a comfortable temperature can be realized for each user (person) located dispersed in each region. .

  (13) A control program according to an aspect of the present invention is a processor (CPU) in a control device (control device 100, 100a, 100b, etc.) that controls air blowing by a blower mechanism (for example, the blower mechanism 210, 220) in a facility. A control program for causing a control process to be executed, wherein the control process acquires temperature information indicating a set temperature that is a target of temperature adjustment in each of the first region and the second region in the facility (for example, step) (S13, S22, S33, etc.) and the temperature information indicates the temperature difference between the set temperatures of the first area and the second area, and the air is sent between the first area and the second area by the blower mechanism. And a control step (for example, steps S17, S27, S36, etc.) for performing control related to the air volume of the airflow.

  If this control program is installed in a computer, the computer functions as a control device (for example, the control devices 100, 100a, 100b, etc.), and controls the air blowing by the air blowing mechanism, so that the space in the facility has a plurality of temperature differences. Can be separated into regions. For this reason, the temperature comfortable for the user (person) located in each area | region can be implement | achieved.
