Description

  The present invention is an air-conditioning system that performs air-conditioning control according to a user in an air-conditioned space.

  Conventionally, there is a technique in which a user in an air-conditioned space is detected by a human sensor and air-conditioning of a zone in which the user is present is performed (for example, see Patent Document 1). In addition, there is a technique in which a temperature sensor is attached to a user's clothing in an air-conditioned space, a comfort level is estimated from information obtained by the temperature sensor, and an indoor unit is controlled based on the comfort level (for example, see Patent Document 2). Furthermore, there is a technique for determining an area where a user is present using a human detection sensor and controlling the wind direction so that an unwarm wind immediately after the start of heating does not directly hit the user (for example, see Patent Document 3).

JP 2012-26697 A Japanese Patent No. 5445539 JP2011-99609A

  The technique of Patent Document 1 is to determine the zone where the user of the air-conditioned space is present and to perform air conditioning on the zone where the user is present, and is not a control reflecting the actual experience of the individual user. I didn't feel comfortable.

  The technique of Patent Document 2 is a control performed by estimating the comfort level of how each user feels from the temperature in clothes and performing the control on the user. There was a problem that I did not know whether I felt uncomfortable. For example, if a person who has a cold is controlled to apply cold air just because the body temperature is high, the cold is worsened.

  Although the technique of patent document 3 can avoid that the warm wind immediately after a heating start hits a user, it is only the moment and is not a system which can obtain comfort continuously.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an air conditioning system that can improve the comfort level of each user in an air-conditioned space.

The air conditioning system according to the present invention is operated by an indoor unit having a wind direction and air volume adjusting unit that adjusts the air direction and the air volume of the conditioned air to be blown into the air conditioned space, and the user's experience information is input. A user terminal that has an input unit and transmits an air conditioning control request including the sensation information input by the input unit; receives an air conditioning control request transmitted from the user terminal; And a central management device that controls the wind direction and air volume adjustment unit of the indoor unit based on the sensation information and position information included in the indoor unit, and the indoor unit includes a human body detection unit that detects the position information of one or more users in the air-conditioned space. The centralized management device creates a user layout by marking the position of the user in the air-conditioned space on the plan view of the air-conditioned space based on the position information detected by the human body detection unit. The user terminal receives the user information input screen and displays it on the user information input screen including the user layout diagram. The mark display on the user layout diagram is selected according to the operation from the input unit. Then, position information related to the position of the user corresponding to the selected mark display is transmitted to the central management apparatus, and the central management apparatus acquires position information from the user terminal .

  Since the air conditioning system of the present invention controls the wind direction and air volume adjustment unit of the indoor unit based on the sensation information input by the user using the user terminal, the control is adapted to the actual sensation of each user in the air-conditioned space. Can be realized.

The unit 20 stores user information input by the user consciously operating the user terminal 200.

Next, the operation will be described.
FIG. 9 is a diagram showing an operation flow at the time of sensor value information acquisition in the centralized management device of the air-conditioning system according to Embodiment 1 of the present invention. The operation information storage unit 50 of the centralized management apparatus 100 stores and updates operation information such as the current operation mode and wind direction of the indoor unit 400 at an appropriate timing, and refers to the operation information storage unit 50, It is assumed that the current operation state of the indoor unit 400 can be grasped on the central management apparatus 100 side.

  The central management apparatus 100 refers to the operation information stored in the operation information storage unit 50, sets the operation mode of the indoor unit 400 to the cooling, dry, or heating mode, and sets the wind direction setting to “swing”. It is determined whether or not the condition of being present is satisfied (S1). If the condition is satisfied, the centralized management device 100 subsequently performs the determination of (S2), and returns to the process of (S1) if the condition is not satisfied. Here, the above description is used for the determination of (S1), but any other condition may be added as long as the above condition is satisfied.

  In (S <b> 2), the central management apparatus 100 determines whether sensor value information exists in the sensor value information accumulation unit 40. Since sensor value information does not exist in the sensor value information accumulation unit 40 for the first time after the start of operation, the process of (S4) is performed in this case. That is, the centralized management device 100 acquires sensor value information from the indoor unit 400 and stores it in the sensor value information accumulation unit 40. If the central management apparatus 100 determines that the sensor value information exists in the sensor value information accumulation unit 40, then the central value management apparatus 100 continues to store the sensor value information in the sensor value information accumulation unit 40 for one minute or longer. It is determined whether it has elapsed (S3). Here, if sensor value information of a plurality of users is stored in the sensor value information accumulation unit 40, it is determined whether there is any sensor value information that has passed one minute or more since it was last saved. to decide.

  Specifically, the determination in (S3) compares the time 43 when the sensor value information accumulation unit 40 was saved with the time returned by 1 minute from the current time, and the time 43 when saved is set back by 1 minute from the current time. If the time is earlier than the last time, it is determined that one minute or more has passed since the data was saved. Here, the data update condition is one minute or longer. However, as long as the data can be updated, the condition time may be shortened or lengthened. Here, the sensor value information is acquired from the indoor unit 400, but other methods may be used as long as similar information is obtained.

  In the determination of (S3), when it is determined that one minute or more has elapsed, the centralized management device 100 acquires new sensor value information from the indoor unit 400 and updates the sensor value information accumulation unit 40 (S4). . The update process of (S4) is performed for each sensor value information for which it has been determined that one minute or more has elapsed since the previous save. With this update process (S4), the sensor value information of each user stored in the sensor value information accumulation unit 40 is updated every minute.

  The central management apparatus 100 performs the operation flow process shown in FIG. 10 in parallel with the operation flow process shown in FIG.

FIG. 10 is a diagram showing an operation flow at the time of user information acquisition in the centralized management device of the air-conditioning system according to Embodiment 1 of the present invention. The process of the operation flow in FIG. 10 is started when, for example, a program for air conditioning control is started on the user terminal 200.
When the central management device 100 recognizes that the air conditioning control program has been started on the user terminal 200, the data processing unit 30 processes the sensor value information stored in the sensor value information accumulating unit 40 and is in the conditioned space. A user layout diagram showing the positions of all users is created (S5). As described above, the sensor value information is the position information of the user, and the central management apparatus 100 creates a user layout based on the position information.

FIG. 11 is a diagram showing an example of a user layout diagram in the air-conditioning system according to Embodiment 1 of the present invention.
The user layout diagram is a diagram in which the position of each user is marked with a white circle on the plan view of the room in which the indoor unit 400 and the desk are shown.

  The centralized management apparatus 100 transmits the user layout created by the data processing unit 30 to the user terminal 200 using the user terminal communication unit 10 (S6).

  The user terminal 200 that has received the user layout diagram displays a user information input screen on the display unit 202 based on the user layout diagram.

FIG. 12 is a diagram illustrating an example of a user information input screen displayed on the user terminal of the air-conditioning system according to Embodiment 1 of the present invention.
The user information input screen is a screen that prompts the user to input his / her position and his / her bodily sensation (hot / comfortable / cold). The user information input screen includes a user arrangement diagram 80 received from the central management apparatus 100, a zoom button 81, a selection button 82, and a transmission button 83. The zoom button 81 is a button for zooming in or zooming out the user layout drawing 80. The selection button 82 is a button for selecting one of a plurality of pieces of bodily sensation information such as hot / comfortable / cold. The transmission button 83 is a button for instructing transmission of an air conditioning control request including the sensation information selected by the selection button 82.

  The user who has confirmed the user information input screen operates the input unit 201 and selects one of the selection buttons 82 to input his / her experience. Further, the user inputs his / her position by operating the input unit 201 to select a mark display corresponding to his / her position from a plurality of mark displays indicated by white circles in the user layout diagram 80. . The display format of the selected mark display is changed from a white circle display to a black circle display so that it can be identified that it has been selected.

  FIG. 12 shows a state where the user position 84 is selected by the user in the air-conditioned space A1 and “hot” is selected by the selection button 82. When the transmission button 83 is pressed in this state, an air conditioning control request including user information including the position information 21 that is the coordinates of the user position 84 and the sensation information 22 such as “hot” is sent from the user terminal 200 to the centralized management device 100. Will be sent to. Note that the user information input screen illustrated in FIG. 12 is merely an example, and is not limited to this screen configuration.

  When receiving the air conditioning control request from the user terminal 200, the user terminal communication unit 10 of the centralized management apparatus 100 stores the user information included in the air conditioning control request in the user input information accumulation unit 20 (S7). At this time, the time 23 at the time of storage is also stored in the user input information accumulation unit 20. Thereby, the user information input at each user terminal 200 is managed by the user input information accumulation unit 20.

  Here, the user information input screen is displayed on the user terminal 200 to input the position information and the sensation information. However, any acquisition means may be used as long as these pieces of information are obtained. For example, the position information is input by the user here, but may be as follows. That is, the central management apparatus 100 may be provided with a position measurement unit 11 (see FIG. 1) that acquires user position information using GPS, and the central management apparatus 100 side may acquire the user's position.

  As a specific usage form of the user terminal 200, for example, when each user in the air-conditioned space positively desires to change to the air-conditioning control according to his / her own experience or to maintain the current air-conditioning control, At this timing, the air conditioning control program is started, and position information and sensation information are input from the user information input screen as described above.

  Next, the operation on the central management apparatus 100 side based on the air conditioning control request transmitted from the user terminal 200 will be described with reference to FIG.

  FIG. 13 is a diagram illustrating an operation flow of the wind direction and air volume control based on the air conditioning control request in the centralized management device of the air conditioning system according to Embodiment 1 of the present invention. Here, the operation for the air-conditioned space A1 (see FIG. 2) will be described. Further, “indoor unit 400” in the following description refers to an indoor unit whose air-conditioning space A1 is an air conditioning target.

(S11)
The central management apparatus 100 refers to the operation information stored in the operation information storage unit 50, sets the operation mode of the indoor unit 400 to the cooling, dry, or heating mode, and sets the wind direction setting to “swing”. It is judged whether or not the condition of being is satisfied. If the condition is not satisfied, the process returns to (S11), and if the condition is satisfied, the process (S12) is performed.

(S12)
The data processing unit 30 of the centralized management device 100 predicts the vertical wind direction angle one second after the current wind direction angle of the indoor unit 400 based on the wind direction information of the motion information stored in the motion information storage unit 50. Since the wind direction setting is “swing” here, the wind direction in the vertical direction changes every moment, and the wind direction changes at, for example, 15 degrees / sec. If the current wind direction is 30 degrees, it can be predicted that the wind direction in the up and down direction after 1 second will be 45 degrees. Here, although the wind direction change speed is 15 degrees / sec, it is not limited to this speed, and may be set as appropriate according to the model of the indoor unit 400 and the like. The reason for predicting the vertical wind direction after 1 second will be described later.

(S13)
Then, the centralized management device 100 checks whether there is a user in the direction of the wind direction angle after 1 second obtained by prediction (hereinafter referred to as the predicted wind direction angle). Specifically, the centralized management device 100 checks whether the sensor value information accumulation unit 40 has sensor value information having the direction information 42 of the same angle α as the predicted wind direction angle. When sensor value information having the direction information 42 of the same angle α as the predicted wind direction angle is in the sensor value information accumulation unit 40, it is determined that there is a user in the direction of the predicted wind direction angle, and the process of (S14) is performed. In that case, the process of (S29) is performed.

(S14)
The centralized management device 100 determines whether there are a plurality of users in the direction of the predicted wind direction angle. If there are a plurality of users, the central management apparatus 100 performs the process of (S15), and if not, the process of (S16) is performed. .

(S15)
The centralized management device 100 determines a user to be controlled from a plurality of users in the direction of the predicted wind direction angle. Here, the control target is selected from among a plurality of users who are in the direction of the predicted wind direction angle and who have operated the user terminal 200 and requested air conditioning control suitable for their own experience. Since not all of the plurality of users who are in the direction of the predicted wind direction angle are requesting the air conditioning control, here, among the plurality of users in the direction of the predicted wind direction angle, The control target is selected from the inside.

  As a specific process for selecting a user to be controlled, the data processing unit 30 creates position information 21 that is a coordinate of each user based on the distance information 41 and the direction information 42 of the sensor value information accumulation unit 40. Then, by searching the user input information accumulation unit 20 using the position information 21 as a search key, first, a user in the direction of the predicted wind direction angle is specified. And the user with the oldest time 23 at the time of preservation | save is determined to be a control object user from the some user who exists in the direction of an estimated wind direction angle. For example, if all the users 1 to 3 of the user input information accumulation unit 20 shown in FIG. 8 are users in the direction of the predicted wind direction angle, “2015/7/31 13:30” and “2015 / 7/31 13:35 ”and“ 2015/7/31 13:37 ”, and user 1 is determined as the user to be controlled. After that, the time 23 when the user 1 is stored is overwritten with the current time.

  With the above processing, when an air conditioning control request is transmitted from each of the plurality of user terminals 200, the transmission target is determined to be the control target user in order from the oldest user.

(S16)
When there is one user who satisfies the condition of (S13), this user is set as a control target user.

(S17-S29)
When the control target user is determined as described above, the centralized management device 100 controls the wind direction and air volume adjustment unit 401 so that air conditioning control suitable for the actual experience of the control target user is performed according to the operation mode of the indoor unit 400. To control. Hereinafter, an example of this air conditioning control will be described.

(S17)
The centralized management device 100 determines whether the operation mode of the indoor unit 400 is operating in the cooling or dry mode.

  When operating in the cooling or dry mode, the central management apparatus 100 performs the process of (S18), and when operating in the other modes, performs the process of (S23).

(S18)
The centralized management device 100 determines whether or not the sensation information 22 of the control target user is “hot”. When the sensation information 22 is “hot”, the process of (S19) is performed, and when the sensation information 22 is not “hot”, the process of (S20) is performed.

(S19)
When the control target user's sensation information 22 is “hot”, the centralized management device 100 controls the wind direction in the left-right direction of the indoor unit 400 so that the control target user is exposed to conditioned air. Specifically, the centralized management device 100 issues a control instruction to the indoor unit 400 via the air conditioning control communication unit 60 so that the wind direction in the left-right direction of the indoor unit 400 is directed to the angle β of the direction information 42 of the control target user. Send. The indoor unit 400 that has received this control instruction controls the wind direction and air volume adjustment unit 401 to perform control according to the control instruction.

  The control according to this control instruction is performed approximately 1 second after the timing when the predicted wind direction angle is predicted in (S12). In other words, at the timing when the control target user is determined and the wind direction control in the horizontal direction toward the control target user is performed, in order to match the vertical wind direction with the control target user, after 1 second in (S12) Predicts the vertical wind direction angle. Here, the wind direction angle is predicted after 1 second, but it is sufficient that the above-described purpose can be achieved. With the above processing, both the vertical wind direction and the horizontal wind direction coincide with the control target user, and conditioned air can be applied to the control target user.

  Then, the air direction is stopped for 1 second when the conditioned air from the indoor unit 400 is hitting the user to be controlled, and the time during which the conditioned air is hitting the user is made longer than the normal “swing”. Also, the air volume is set to be a strong wind. Accordingly, it is possible to concentrate the cold air on the user who feels “hot” during the cooling or dry mode operation, so that the comfort level of the user can be improved. Here, the wind direction stop time is 1 second and the air volume is strong. However, any wind direction and air volume may be used as long as the user's comfort level can be increased. Further, control other than the wind direction and the air volume may be added.

(S20)
When the sensation information 22 is not “hot” in the determination of (S18), the centralized management device 100 subsequently determines whether the sensation information 22 of the control target user is “cold”. If the sensation information 22 is “cold”, the process of (S21) is performed, and if the sensation information 22 is not “cold”, the process of (S22) is performed.

(S21)
When the control target user's sensation information 22 is “cold”, the centralized management device 100 controls the wind direction in the left-right direction of the indoor unit 400 so that the control target user is not exposed to conditioned air. Specifically, the centralized management device 100 passes the indoor unit 400 via the air conditioning control communication unit 60 so that the wind direction in the left-right direction of the indoor unit 400 faces outside the angle β of the direction information 42 of the sensor value information of the control target user. A control instruction is transmitted to the machine 400. The air volume is the currently set air volume.

(S22)
If the control target user's sensation information 22 is neither “hot” nor “cold”, the central management apparatus 100 determines that “comfort” has been selected, and continues the current driving. In other words, the vertical wind direction is swing-operated as usual, the left-right wind direction is kept at the current setting, and the indoor unit 400 is operated with the air volume kept at the current setting. As a specific process, no control instruction is transmitted from the centralized management device 100.

(S23)
In the determination of (S17), if the operation mode of the indoor unit 400 is not the cooling or dry mode, it is subsequently determined whether it is heating. When operating in the heating mode, the process of (S24) is performed, and when not operating in the heating mode, the process returns to (S11).

(S24)
The centralized management device 100 determines whether or not the sensation information 22 of the control target user is “hot”. When the sensation information 22 is “hot”, the process of (S25) is performed, and when the sensation information 22 is not “hot”, the process returns to (S11).

(S25)
When the sensible information 22 of the control target user is “hot”, the centralized management device 100 controls the wind direction in the left-right direction of the indoor unit 400 so that the control target user is not exposed to conditioned air. Specifically, the centralized management device 100 passes the indoor unit 400 via the air conditioning control communication unit 60 so that the wind direction in the left-right direction of the indoor unit 400 faces outside the angle β of the direction information 42 of the sensor value information of the control target user. A control instruction is transmitted to the machine 400. The air volume is the currently set air volume.

(S26)
When the sensation information 22 of the control target user is not “hot” in the determination of (S24), the centralized management device 100 subsequently determines whether the sensation information 22 of the control target user is “cold”. When the sensation information 22 is “cold”, the process of (S27) is performed, and when the sensation information 22 is not cold, the process of (S28) is performed.

(S27)
When the control target user's sensation information 22 is “cold”, the centralized management device 100 controls the wind direction in the left-right direction of the indoor unit 400 so that the control target user is exposed to conditioned air. Specifically, the centralized management device 100 issues a control instruction to the indoor unit 400 via the air conditioning control communication unit 60 so that the wind direction in the left-right direction of the indoor unit 400 is directed to the angle β of the direction information 42 of the control target user. Send. The indoor unit 400 that has received this control instruction controls the wind direction and air volume adjustment unit 401 to perform control according to the control instruction.

  The control according to this control instruction is performed approximately 1 second after the timing when the predicted wind direction angle is predicted in (S12). In other words, at the timing when the control target user is determined and the wind direction control in the horizontal direction toward the control target user is performed, in order to match the vertical wind direction with the control target user, after 1 second in (S12) Predicts the vertical wind direction angle. Here, the wind direction angle is predicted after 1 second, but it is sufficient that the above-described purpose can be achieved. With the above processing, both the vertical wind direction and the horizontal wind direction coincide with the control target user, and conditioned air can be applied to the control target user.

  Then, the air direction is stopped for 1 second when the conditioned air from the indoor unit 400 is hitting the user to be controlled, and the time during which the conditioned air is hitting the user is made longer than the normal “swing”. Also, the air volume is set to be a strong wind. Accordingly, it is possible to concentrate and apply hot air to a user who feels “cold” during the heating mode operation, so that the comfort level of the user can be improved. Here, the wind direction stop time is 1 second and the air volume is strong. However, any wind direction and air volume may be used as long as the user's comfort level can be increased. Further, control other than the wind direction and the air volume may be added.

(S28)
In the determination of (S24), if the control target user is neither “hot” nor “cold”, the central management apparatus 100 determines that “comfort” is selected, and continues the current driving. In other words, the vertical wind direction is swing-operated as usual, the left-right wind direction is kept at the current setting, and the indoor unit 400 is operated with the air volume kept at the current setting. As a specific process, no control instruction is transmitted from the centralized management device 100.

(S29)
If the central management device 100 determines in the determination of (S13) that there is no user in the direction of the predicted wind direction angle, the central management device 100 continues the current operation. In other words, the vertical wind direction is swing-operated as usual, the left-right wind direction is kept at the current setting, and the indoor unit 400 is operated with the air volume kept at the current setting. As a specific process, no control instruction is transmitted from the centralized management device 100.

  After performing the air conditioning control suitable for the individual user to be controlled in the above processes (S13) to (S29), the process returns to (S11) and the same process is repeated. When there are a plurality of users who have requested air conditioning control in the same air conditioning space, the air conditioning control suitable for each user is sequentially performed. Thus, since the air-conditioning control is performed according to the user's own experience in the air-conditioned space, an effect that the user feels comfortable can be obtained.

  In addition, although the operation | movement description for one air-conditioned space A1 was performed here, in the air-conditioning control system of this Embodiment 1, it is the same also in each indoor unit 400 of other air-conditioned space A2-A6. Operation is performed.

  In the above description, the user's experience information is selected from hot / comfort / cold, but other experience information may be added. For example, “hot” may be further divided and hot (large) / hot (small) may be added. In the case of adding these, it may be determined by adding further conditions after both or one of (S18) and (S24).

  As described above, according to the first embodiment, the air volume and direction of the indoor unit 400 are controlled based on the sensation information input by the user himself and the position information of the user. Comfortable control suited to the experience can be performed. Specifically, the air direction is controlled so that conditioned air is blown toward the user, and the air volume is controlled to match the user's experience, thereby improving the user's comfort level.

  In addition, since the user information input screen that prompts the user to input experience information is displayed on the display unit 202 of the user terminal 200, the user can input experience information according to the user information input screen. Specifically, the sensation information can be input by selecting the selection button 82 on the user information input screen, and the operation is simple.

  Further, when the user inputs his / her position, it is only necessary to select a mark display corresponding to the user's position arranged on the user layout diagram, so that the position information can be easily input.

  Further, when the position measurement unit 11 provided on the central management apparatus 100 side acquires the user's position, the user only inputs the sensation information when requesting the air conditioning control suitable for his / her sensation. Because it is good, the operation is simple.

  In addition, when there are multiple users who have requested air conditioning control in the air-conditioned space, the control that suits the user's experience is performed in order of the timing when the air-conditioning control request was made, Even if there are a plurality of users who have made air conditioning control requests, this can be handled.

  Moreover, although the control content was demonstrated for the air-conditioned space of one indoor unit 400, the same operation | movement can be performed in each air-conditioned space.

  In the first embodiment, an example is shown in which a plurality of indoor units 400 are installed on the ceiling and the air-conditioned space is below the indoor unit 400. However, one indoor unit 400 is installed on the horizontal wall and the air-conditioned space is The present invention can also be applied to the case where is the side of the indoor unit 400.
