Remember me. The current position receiving unit 41 is not limited to a specific configuration, and the connection between the air conditioner control device 40 and the communication circuit network 30 may be performed by wire or wirelessly.

  When the control unit 42 receives the reception completion notification from the current position receiving unit 41, the received position (X1, Y1, Z1) of the mobile terminal 20 and the air conditioner 50 stored in the air conditioner presence position storage unit 44 are stored. The distance calculation unit 43 is instructed to calculate the distance between the two positions (X2, Y2, Z2). In addition, a command signal to the air conditioner 50 is transmitted to the air conditioner control transmission unit 46 with reference to the calculated distance and the processing content stored in the air conditioner control content storage unit 45.

  The distance calculation unit 43 calculates the distance between the mobile terminal 20 and the air conditioner 50 from the position (X1, Y1, Z1) of the mobile terminal 20 and the position (X2, Y2, Z2) of the air conditioner 50, and calculates the distance to the control unit 42. Send the result.

  The air conditioner presence position storage unit 44 stores the position (X2, Y2, Z2) of the air conditioner 50. The position (X1, Y1, Z1) of the portable terminal 20 and the position (X2, Y2, Z2) of the air conditioner 50 may be stored in the same format (format). Note that the positions (X2, Y2, Z2) are preferably stored via the air conditioner 50 by operating the remote controller 60 when the air conditioner control device 40 and the air conditioner 50 are installed, for example.

  The update of the position (X1, Y1, Z1) of the mobile terminal 20 is performed at a frequency (for example, at intervals of 1 second) that does not place an excessive burden on the processors and memories provided in the devices constituting the air conditioning control system. Just do it. The same applies to the timing of commanding the air conditioner control transmission unit 46.

  The air conditioner control content storage unit 45 stores the processing content performed by the control unit 42 as, for example, a table.

  The air conditioner control transmission unit 46 transmits a command signal or the like from the air conditioner control device 40 to the air conditioner control reception unit 51.

  The air conditioner 50 includes an air conditioner control receiver 51, an air conditioner controller 52, and an infrared receiver 53.

  The air conditioner control reception unit 51 receives a command signal or the like transmitted from the air conditioner control transmission unit 46. The air conditioner control transmission unit 46 and the air conditioner control reception unit 51 are not limited to specific configurations, and the connection between the air conditioner control transmission unit 46 and the air conditioner control reception unit 51 may be performed by wire, It may be performed wirelessly.

  The air conditioner control unit 52 controls the cooling / heating operation of the air conditioner 50 based on the command signal received from the air conditioner control receiving unit 51. The infrared receiver 53 receives a signal from an infrared transmitter 62 described later and transmits the signal to the air conditioner controller 52.

  The remote control 60 includes an operation unit 61 and an infrared transmission unit 62. The operation unit 61 has a configuration (for example, operation buttons) that allows the user to set the temperature, air volume, and the like of the air conditioner 50, and transmits the infrared transmission unit 62. The infrared transmitter 62 receives a signal from the operation unit 61 and transmits the signal to the infrared receiver 53 provided in the air conditioner 50.

  The remote controller 60 may be, for example, an infrared communication wireless remote controller, but is not limited to a specific configuration. The remote controller 60 may be a wireless remote controller that performs wireless communication, or may be wired to the air conditioner 50. Alternatively, the operation by the remote controller 60 may be replaced by a switch (emergency operation switch) provided in the air conditioner 50.

  Here, an operation example of the air conditioning control system having the above-described configuration will be described with reference to Table 1 and FIG. Table 1 shows an example of the processing content stored in the air conditioner control content storage unit 45.

  The control unit 42 determines the processing content from the calculation result of the distance calculation unit 43 and the processing content of Table 1. That is, when the distance between the position (X1, Y1, Z1) and the position (X2, Y2, Z2) exceeds a threshold value (200 m in this case) (for example, 300 m), the control unit 42 No command is given to the air conditioner 50, and the air conditioner 50 maintains the off state.

  When the distance between the position (X1, Y1, Z1) and the position (X2, Y2, Z2) is equal to or less than a predetermined distance (200 m in this case) (for example, 150 m), the control unit 42 controls the air conditioner. A control signal is transmitted to the air conditioner controller 52 via the transmitter 46 and the air conditioner control receiver 51. The air conditioner control unit 52 controls the air conditioner 50 in accordance with the control signal received from the air conditioner control receiving unit 51. That is, the air conditioner 50 that is turned off is turned on to start operation.

  The control unit 42 determines whether or not the mobile terminal 20 has been stopped for a long time immediately after receiving the control signal as described above. For example, when the portable terminal 20 is not approaching 5 m or more per minute (when the distance between the position (X1, Y1, Z1) and the position (X2, Y2, Z2) is less than 5 m per minute) Then, it is determined that the user of the portable terminal 20 is not approaching, and the air conditioner 50 is turned off. That is, even if it is in the ON section, if the amount of decrease in distance per unit time is less than the threshold value, it is determined that the user is not approaching, and the air conditioner 50 that is the control target device is turned off. To do. However, even after the air conditioner 50 is turned off in this way, the frequency with which the control unit 42 refers to the calculation result of the distance calculation unit 43 is maintained in the same manner as when it is turned on, and the position of the mobile terminal 20 is kept in detail. When the mobile terminal 20 approaches 5 m or more per minute (the distance between the position (X1, Y1, Z1) and the position (X2, Y2, Z2) is 5 m or more per minute), the mobile terminal 20 It is determined that the user is approaching, and the air conditioner 50 is turned on again. That is, when the amount of decrease in distance per unit time in the ON section is equal to or greater than the threshold value, it is determined that the user is approaching, and the air conditioner 50 that is the device to be controlled is turned on. If the distance between the position (X1, Y1, Z1) and the position (X2, Y2, Z2) exceeds the threshold value (200 m in this case) again, the air conditioner 50 is turned off. Note that when the control unit 42 determines whether or not the mobile terminal 20 has been stopped for a long time, the frequency of referring to the calculation result of the distance calculation unit 43 may be increased.

  In the operation example of the air conditioning control system described above, the setting at the time of the operation of the air conditioner may refer to the history of the previous operation or may be referred to by a user preset by the remote controller. For example, if the previous operation is a cooling operation, the cooling operation may be performed when the operation is on, and if the previous operation is a heating operation, the heating operation may be performed when the operation is on. Such an operation history may be stored in a storage area (not shown) provided in the air conditioner control unit 52.

  FIG. 3 is a diagram illustrating a relationship between time (horizontal axis) and distance (vertical axis) in the operation example of the air conditioning control system.

  When the mobile terminal 20 in the off section approaches the position (X2, Y2, Z2), the mobile terminal 20 enters the on section at the point B, and the air conditioner 50 is automatically turned on (points A to C).

  And since the portable terminal 20 goes away from a position (X2, Y2, Z2) and comes out to an OFF area at the point D, the air conditioner 50 turns off automatically (point C-point E).

  The mobile terminal 20 that has entered the off section again approaches the position (X2, Y2, Z2), reenters the on section at point F, and the air conditioner 50 is automatically turned on (points E to G).

  Thereafter, the mobile terminal 20 stops at a certain point in the ON section (point G to point H). Then, since the decrease amount of the distance per unit time is small from the point G to the point H, the control unit 42 of the air conditioner control device 40 indicates that the mobile terminal 20 is not approaching the position (X2, Y2, Z2). Judgment is made and the air conditioner 50 is automatically turned off. Then, since the amount of decrease in the distance per unit time of the mobile terminal 20 increases from the point H, the air conditioner 50 is automatically turned on again.

  As described above, the air conditioner control device 40 of the present embodiment performs control to stop the air conditioner 50 when the mobile terminal 20 stops in the middle of approaching or moves away from a predetermined section. .

  In addition, when there are a plurality of users of the air conditioning control system described above, when a user other than the user of the mobile terminal 20 is present in the air conditioning area, the operation with the remote controller 60 is prioritized. And it is sufficient. Moreover, you may set so that said air conditioning control system may be stopped by the remote control 60, and the air conditioner 50 may be controlled.

  In order to detect whether there are a plurality of users of the air conditioning control system, that is, whether another user exists in the air conditioning area, the air conditioner 50 (indoor unit) is used. If a human sensor is installed, the portable terminal 20 is outside the air conditioning area, and the human sensor detects the presence of a person, it may be determined that there are a plurality of users of the air conditioning control system. .

  When the air conditioner 50 is off (state S2), the user carrying the mobile terminal 20 approaches the position (X2, Y2, Z2), and the position (X1, Y1, Z1) and the position (X2, Y2). , Z2) is less than the threshold value, the air conditioner control device 40 detects this, and the air conditioner 50 is automatically turned on (state S2 to state S3).

  After the air conditioner 50 is automatically turned on (state S3), the user of the portable terminal 20 moves out of the air conditioning area again, and the distance between the position (X1, Y1, Z1) and the position (X2, Y2, Z2) is increased. When the threshold value is exceeded, the air conditioner control device 40 detects this and automatically turns off the air conditioner 50 again (state S3 to state S2).

  Or, when the distance between the position (X1, Y1, Z1) and the position (X2, Y2, Z2) is less than or equal to the threshold value, but the distance does not decrease thereafter (when the decrease in distance per unit time is small) ) Is the same.

  When there are a plurality of users, the air conditioner 50 prioritizes the command from the remote controller 60 and does not perform automatic operation control, but sets the state S1 or S2.
