Description

Air conditioning system and application program

Technical Field

The present invention relates to an air conditioning system and an application program for performing air conditioning by a plurality of indoor units installed in a building such as an office or a store.

Background

Generally, when a plurality of indoor units are operated in a living room of a building in which the plurality of indoor units are installed, a centralized controller is generally used. In this case, the indoor room layout is displayed on the screen of the centralized controller, and the image in which the image of the indoor unit is arranged in the indoor room layout is displayed on the screen so that the installation position of the indoor unit is known. Thus, a method is generally performed in which the user checks the position of the user on the room layout diagram and operates the indoor unit located near the user.

However, with this method, particularly when the indoor unit is a concealed package, it is difficult to visually confirm the indoor unit located near the user. Therefore, there is a problem that even if a room layout diagram in a room in which the indoor units are arranged is displayed on a screen of the centralized controller, it is difficult for a user to recognize the indoor units in the vicinity of the user.

As a technique for solving this problem, there is disclosed a technique in which a remote controller device capable of exchanging data signals with a plurality of devices using bidirectional radio waves is provided, and data including ID codes held by the plurality of devices at the time of initial setting and a result of averaging the radio wave intensity of the data signal for a predetermined time are registered in association with each other, whereby the devices under their own management can be easily operated (for example, see patent document 1).

In patent document 1, a plurality of devices such as air conditioners which are objects to be operated have inherent IDs, and these devices notify the remote controller of the IDs at the time of initial setting, and register the remote controller with the intensity of radio waves emitted from the devices in association with the IDs. This enables operation of only the devices around the user as the operation target.

Patent document 1: japanese patent laid-open publication No. 2003-284169

However, in patent document 1, since the ID is registered in the remote controller at the time of initial setting, in an environment in which the position of the device to be operated frequently changes, it takes time and effort to perform initial setting, and there is a problem that the operation target cannot be changed flexibly.

Disclosure of Invention

The present invention has been made to solve the above-described problems, and an object thereof is to provide an air conditioning system and an application program that can flexibly change an indoor unit that is a target to be collectively set for operation.

An air conditioning system according to the present invention includes: a plurality of indoor units having a wireless communication unit for emitting radio waves; and a portable terminal unit which performs wireless communication with each of the wireless communication units,

the portable terminal unit includes: an air conditioner operation input unit that receives an input from a user; an air conditioner information display unit for displaying information to a user; and an air conditioner operation management unit that controls the indoor units, wherein the air conditioner operation management unit displays a list of the indoor units on the air conditioner information display unit and performs a display that prompts selection of the indoor units that are to be set as objects to be collectively operated, and sets the selected indoor units as a group when the indoor units are selected from the air conditioner operation input unit.

Further, the application program according to the present invention causes a computer to execute: displaying a list of the indoor units on a display means for displaying information to a user, and displaying a display for urging selection of the indoor units to be set as objects to be operated collectively; and setting the selected indoor units as a group when the indoor units are selected from an input means for receiving an input from a user.

According to the air conditioning system and the application program of the present invention, the air conditioner operation management unit causes the air conditioner information display unit to display a list of indoor units and to perform a display for urging selection of indoor units to be set as objects to be operated collectively. When the indoor unit is selected from the air conditioner operation input unit, the selected indoor unit is set as a group. Therefore, the group setting can be easily performed, and the indoor units to be set can be flexibly changed.

Detailed Description

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to the embodiments described below. In the following drawings, the relationship between the sizes of the respective components may be different from the actual one.

Embodiment mode 1

Fig. 1 is a schematic diagram showing a configuration of an air conditioning system 100 according to embodiment 1 of the present invention.

First, the configuration of the air conditioning system 100 according to embodiment 1 will be described.

The air conditioning system 100 includes a plurality of indoor units 2 that condition air in a space to be air-conditioned, an outdoor unit 5 that forms a refrigerant circuit with the indoor units 2, and a portable terminal unit 6 that communicates with the indoor units 2. The indoor unit 2 includes a wireless communication unit 3 that emits radio waves and a human sensing detection unit 4 that detects a human.

The indoor unit 2 and the outdoor unit 5 constitute a refrigerant circuit in which a refrigerant circulates, and each refrigerant system is connected by a wired communication line unit 7. In addition, a plurality of indoor units 2 and outdoor units 5 may be provided in one refrigerant system. The indoor unit 2 and the outdoor unit 5 can communicate bidirectionally via the wired communication line unit 7.

The wireless communication unit 3 and the human sensing detection unit 4 are connected to the indoor unit 2 through a wired communication line unit 7 capable of bidirectional communication. In embodiment 1, one wireless communication unit 3 is connected to one indoor unit 2, but the present invention is not limited to this, and for example, one wireless communication unit 3 may be connected to two indoor units 2. That is, one wireless communication unit 3 may be shared by a plurality of indoor units 2.

The wired communication line unit 7 is configured by a general communication standard such as Ethernet (registered trademark) or two-wire UART (Universal Asynchronous Receiver Transmitter) or a separate communication standard.

The wireless communication unit 3 and the human sensing detection unit 4 may be independent of the indoor unit 2 or may be incorporated in the indoor unit 2. In the case where the wireless communication unit 3 and the human sensing detection unit 4 are built into the indoor unit 2, the wired communication line unit 7 may be configured by a general communication standard such as I2C (Inter-Integrated Circuit bus).

The wireless communication section 3 can bidirectionally communicate with the portable terminal section 6 via the wireless communication line section 8. The wireless communication line unit 8 is configured by a general communication standard such as Wi-Fi (registered trademark), Bluetooth (registered trademark), or ZigBee (registered trademark).

The human sensing detection unit 4 is used to detect a human being located in the periphery of the indoor unit 2, i.e., at a predetermined distance from the indoor unit 2, and is composed of a thermal imager, a camera, or a human sensing sensor. Here, the predetermined distance from the indoor unit 2 is a distance in the air conditioning target space of the indoor unit 2. The air conditioning system 100 according to embodiment 1 may not include the human sensing detection unit 4.

The wireless communication unit 3 and the human sensing detection unit 4 are provided in the main body of the indoor unit 2, or in the vicinity of the outlet, the inlet, or the duct of the indoor unit 2 when the unit is a concealed package. The wireless communication unit 3 and the human sensing detection unit 4 may be built in the indoor unit 2 or externally mounted.

The portable terminal unit 6 is, for example, a commercially available smartphone or tablet PC, and can perform wireless communication with the wireless communication unit 3. An application program for operating the air conditioning system 100 is installed in the portable terminal unit 6.

Fig. 2 is a block diagram showing an internal processing configuration of the air conditioning system 100 according to embodiment 1 of the present invention.

Next, an internal processing configuration of the air conditioning system 100 according to embodiment 1 will be described.

The indoor unit 2 includes an indoor unit control unit 11. The indoor unit control unit 11 controls the indoor units 2 so as to perform an air conditioning operation in conjunction with the outdoor unit 5 and the other indoor units 2 of the same refrigerant system connected through the wired communication line unit 7.

The wireless communication unit 3 includes a wireless ID unit 12 and a wireless transmission/reception unit 13. The wireless communication unit 3 includes a control circuit formed of an MCU, a RAM, a ROM, or the like as a control circuit for the wireless ID unit 12 and the wireless transmission/reception unit 13.

The wireless ID unit 12 is used to record a unique ID assigned to the wireless communication unit 3, and is configured by a ROM or the like provided in the wireless communication unit 3. As the ID, a BD address, a MAC address, and the like can be used.

The wireless transmission/reception unit 13 performs signal transmission and reception of the wireless communication line unit 8, and is configured by a digital signal processing circuit, an analog signal processing circuit, an antenna circuit, or the like.

The outdoor unit 5 includes an outdoor unit control unit 14. The outdoor unit control unit 14 controls the outdoor unit 5 so as to perform an air conditioning operation in conjunction with the indoor unit 2 and the other outdoor unit 5 of the same refrigerant system connected through the wired communication line unit 7.

The portable terminal unit 6 includes a portable-side wireless communication unit 9, an air conditioner operation management unit 15, an air conditioner operation input unit 16, and an air conditioner information display unit 17. The portable terminal unit 6 is provided with an application program for executing processing for detecting radio waves transmitted from the wireless transmission/reception unit 13, processing for transmitting an air conditioning operation command, which will be described later, to the wireless transmission/reception unit 13, and the like. Here, the application installed in the portable terminal unit 6 is stored in the air conditioner operation management unit 15, but may be stored in a storage unit other than the air conditioner operation management unit 15.

The portable-side wireless communication unit 9 has the same function as the wireless communication unit 3 provided in the indoor unit 2, and can be realized by the original function of the portable terminal unit 6.

The air conditioner operation management unit 15 controls setting operations such as start of operation, stop of operation, and temperature setting of the indoor unit 2, and controls the wireless communication unit 3 provided in the indoor unit 2, by an application program. The air conditioner operation management unit 15 has a function of measuring the radio wave intensity of the Received radio wave, for example, the Received Signal intensity (RSSI) by an application. The air conditioner operation management unit 15 has a function of recording the wireless ID of the wireless communication unit 3 provided in the indoor unit 2 by an application program, and the function of recording the wireless ID can be realized by an MCU, a RAM, a ROM flash memory, or the like.

Further, when the portable terminal unit 6 receives a radio wave from the wireless communication unit 3 provided in the indoor unit 2 and determines that the indoor unit 2 is in the vicinity of the portable terminal unit 6, the air conditioner operation management unit 15 records a wireless ID. Here, the radio wave intensity of the radio wave is related to the distance, and it can be determined that the indoor unit 2 including the radio communication unit 3 which emits the radio wave with a strong radio wave intensity is located closer to the portable terminal unit 6. Therefore, the air conditioner operation management unit 15 determines whether or not the indoor unit 2 is in the vicinity of the portable terminal unit 6 based on the radio wave intensity of the radio wave received from the wireless communication unit 3 provided in the indoor unit 2. Further, when the portable terminal unit 6 does not receive the radio wave from the wireless communication unit 3 of the indoor unit 2 for a certain period of time, the air conditioner operation management unit 15 determines that the indoor unit 2 is not near the portable terminal unit 6, and erases the stored wireless ID.

The air conditioner operation input unit 16 is used for inputting setting operations such as start of operation, stop of operation, and temperature setting of the indoor unit 2 from the portable terminal unit 6 by a user, and is configured by buttons, a touch panel, and the like provided in the portable terminal unit 6.

The air conditioner operation input unit 16 can perform setting operations such as operation start, operation stop, and temperature setting by an application program executed in the portable terminal unit 6. The portable-side wireless communication unit 9 can communicate with the wireless communication unit 3 provided in the indoor unit 2 by an application program executed in the portable terminal unit 6.

The air conditioner information display unit 17 displays necessary information when a user performs setting operations such as start of operation, stop of operation, and temperature setting on the indoor unit 2 from the portable terminal unit 6, and is configured by a touch panel or the like provided in the portable terminal unit 6. The air conditioner operation input unit 16 and the air conditioner information display unit 17 may be independent from each other or may be integrated.

The radio waves transmitted and received by the wireless communication unit 3 and the portable wireless communication unit 9 include wireless ID information of the sender, address information of the sender, and operation instruction information for the indoor unit 2.

The air conditioning system 100 according to embodiment 1 allows a user to manually select the indoor units 2 to be grouped, that is, to set as a group, based on the radio wave intensity of the wireless communication unit 3 provided in each indoor unit 2, and sets the selected indoor units 2 as a group. The group also includes a case where the group of indoor units 2 to be set is set only once, that is, a case where the group selected once is set to be released from the group setting thereafter.

Fig. 3 is a flowchart showing a process of setting the groups of the indoor units 2 by the portable terminal unit 6 of the air conditioning system 100 according to embodiment 1 of the present invention. Fig. 4 is a diagram illustrating a group of air conditioning systems 100 according to embodiment 1 of the present invention.

Hereinafter, a process of setting the groups of the indoor units 2 by the portable terminal unit 6 of the air conditioning system 100 according to embodiment 1 will be described with reference to fig. 3 and 4.

(step S501)

Upon receiving the input of the user ID from the air conditioner operation input unit 16, the air conditioner operation management unit 15 determines whether or not the user is a manager based on the information about the user ID. Among them, information on the user ID is stored in the air conditioner operation management unit 15. If the air conditioner operation management unit 15 determines that the user is the manager (yes), the process proceeds to step S502. On the other hand, if the air conditioner operation management unit 15 determines that the user is not the manager (no), the process proceeds to step S507. The information on the user ID may be stored in a storage unit other than the air conditioner operation management unit 15.

(step S502)

The air conditioner operation management unit 15 determines whether or not a group is set in advance. Here, the group is the group of indoor units 2 to be collectively set as objects to be operated. As shown in fig. 4, for example, when two indoor units 2 belonging to the group 1 are provided, if the group 1 is selected and an operation start operation is performed on the group 1, an operation start command is transmitted to all of the two indoor units 2 belonging to the group 1. The group information is stored in the air conditioner operation management unit 15 by associating the group number with the information of the wireless ID of the wireless communication unit 3 of the indoor unit 2 belonging to the group. If the air conditioner operation management unit 15 determines that a group is set in advance (yes), the process proceeds to step S503. On the other hand, if the air conditioner operation management unit 15 determines that there is no preset group (no), the process proceeds to step S504. The group information may be stored in a storage unit other than the air conditioner operation management unit 15.

(step S503)

The air conditioner operation management unit 15 causes the air conditioner information display unit 17 to display a message prompting the user to input whether or not to reset the group. After the user has made an input from the air conditioner operation input unit 16 as to whether or not to perform the group resetting, the air conditioner operation management unit 15 determines whether or not the input for performing the group resetting is received from the air conditioner operation input unit 16. When the air conditioner operation management unit 15 determines that an input for resetting the group is received from the air conditioner operation input unit 16 (yes), the process proceeds to step S504. On the other hand, when it is determined that the air conditioner operation management unit 15 has received an input from the air conditioner operation input unit 16 that the group is not to be reset (no), the process proceeds to step S507.

(step S504)

The air conditioner operation management unit 15 displays a list of the indoor units 2 on the air conditioner information display unit 17, and also displays a list urging selection of the indoor units 2 to be set collectively, that is, selection of the indoor units 2 to be set as a group.

(step S505)

The air conditioner operation management unit 15 determines whether or not the selection of the indoor unit 2 to be set as a group is performed from the air conditioner operation input unit 16, that is, whether or not the input of the group setting is accepted. When the air conditioner operation management unit 15 determines that the input of the group setting is received from the air conditioner operation input unit 16 (yes), the process proceeds to step S506. On the other hand, when the air conditioner operation management unit 15 determines that the input of the group setting is not received from the air conditioner operation input unit 16 (no), it waits until the input of the group setting is received.

(step S506)

The air conditioner operation management unit 15 associates and registers the group number with the information of the wireless ID of the wireless communication unit 3 of the indoor unit 2 belonging to the group.

(step S507)

The air conditioner operation management unit 15 determines whether or not input of setting operations such as start of operation, stop of operation, and temperature setting for the group or the indoor unit 2 and selection of the group or the indoor unit 2 to be set are accepted from the air conditioner operation input unit 16. When the air conditioner operation management unit 15 determines that an input such as a setting operation is received from the air conditioner operation input unit 16 (yes), the process proceeds to step S508. On the other hand, when the air conditioner operation management unit 15 determines that the input of the setting operation or the like is not received from the air conditioner operation input unit 16 (no), it waits until the input of the setting operation is received.

(step S508)

The air conditioner operation management unit 15 transmits an air conditioner operation command to all of the wireless communication unit 3 of the selected indoor unit 2 and the wireless communication unit 3 of the indoor unit 2 having the wireless ID registered in the selected group. Here, the air conditioning operation command includes an operation start command for starting the air conditioning operation, a setting change command for changing the operation mode, setting temperature, wind direction, wind intensity, and the like, and an operation stop command for stopping the air conditioning operation.

Then, the indoor unit 2 that has received the air conditioning operation command performs setting operations such as operation start, operation stop, and temperature setting.

As described above, the air conditioning system 100 according to embodiment 1 includes: a plurality of indoor units 2 having a wireless communication unit 3 for emitting radio waves; and a portable terminal unit 6 that performs wireless communication with each wireless communication unit 3. The portable terminal unit 6 includes an air conditioner operation input unit 16 for receiving an input from a user, an air conditioner information display unit 17 for displaying information to the user, and an air conditioner operation management unit 15 for controlling the indoor unit 2. The air conditioner operation management unit 15 displays a list of the indoor units 2 on the air conditioner information display unit 17, and also displays a display for urging selection of the indoor units 2 to be set collectively. When the indoor unit 2 is selected from the air conditioner operation input unit 16, the air conditioner operation management unit 15 sets the selected indoor unit 2 as a group.

Further, the application program according to embodiment 1 causes a computer to execute: a display unit for displaying information to a user, the display unit displaying a list of the indoor units 2 and prompting the user to select the indoor units 2 to be set as objects of operation; and when the indoor unit 2 is selected from the input means for receiving an input from the user, the selected indoor unit 2 is set as a group.

According to the air conditioning system 100 and the application program according to embodiment 1, the air conditioner operation management unit 15 displays a list of the indoor units 2 on the air conditioner information display unit 17, and also displays a display for urging selection of the indoor units 2 to be set as objects to be operated collectively. When the indoor units 2 are selected from the air conditioner operation input unit 16, the selected indoor units 2 are set as a group. Therefore, the group setting can be easily performed, and the indoor unit 2 to be set can be flexibly changed.

Embodiment mode 2

Hereinafter, although embodiment 2 of the present invention will be described, descriptions of the same parts as embodiment 1 will be omitted, and the same reference numerals will be given to the same or corresponding parts as embodiment 1.

The air conditioning system 100 according to embodiment 2 automatically determines the indoor unit 2 to be operated based on the radio wave intensity of the wireless communication unit 3 provided in each indoor unit 2.

Fig. 5 is a flowchart showing processing performed until the operation of the indoor unit 2 on the portable terminal unit 6 side of the air conditioning system 100 according to embodiment 2 of the present invention is started.

Next, the processing of the air conditioning system 100 according to embodiment 2 until the operation of the indoor unit 2 is started on the portable terminal unit 6 side will be described with reference to fig. 5.

(step S101)

The wireless communication section 3 of the indoor unit 2 emits radio waves at a constant radio wave intensity. Here, each wireless communication section 3 emits radio waves at the same radio wave intensity. In addition, each wireless communication section 3 emits radio waves regardless of on/off of the power supply of each indoor unit 2. When receiving an operation start input from the air conditioner operation input unit 16, the air conditioner operation management unit 15 starts detection of radio waves emitted from the wireless communication unit 3 of the indoor unit 2 using the portable wireless communication unit 9. Also, the air conditioner operation management portion 15 starts measuring the time from the start of the radio wave detection.

(step S102)

The air conditioner operation management unit 15 determines whether or not the time from the start of radio wave detection has reached the detection end time. Here, the detection end time is a preset time and is a time at which the air conditioner operation management unit 15 detects a radio wave. When the air conditioner operation management unit 15 determines that the time from the start of radio wave detection has reached the detection end time (yes), the operation start processing of the indoor unit 2 is ended. On the other hand, in a case where the air conditioner operation management portion 15 determines that the time from the start of radio wave detection does not reach the detection end time (no), the detection of radio waves is continued.

(step S103)

When the air conditioner operation management unit 15 detects a radio wave (yes), the process proceeds to step S104. On the other hand, if the air conditioner operation management unit 15 does not detect the radio wave (no), the operation start processing of the indoor unit 2 is ended. However, when the air conditioner operation managing section 15 does not detect the radio wave, it is also possible to notify the portable terminal section 6 of the result of the inoperable state by means of pop-up or the like. Alternatively, the air conditioner operation management unit 15 may continue the process of detecting the radio wave until the operation end input is received from the air conditioner operation input unit 16.

(step S104)

The air conditioner operation management unit 15 confirms the radio ID of the wireless communication unit 3 of the sender of the detected radio wave, and starts the measurement of the radio wave intensity. Also, the air conditioner operation management portion 15 resets the measurement of the time from the start of the radio wave detection. Here, the air conditioner operation management unit 15 determines the radio wave intensity of the detected radio wave by using an average or median value based on the measurement results of a plurality of times in order to determine the fluctuation of the radio wave intensity.

(step S105)

The air conditioner operation management unit 15 determines whether or not the radio wave intensity of the detected radio wave determined in the process of step S104 is equal to or higher than a preset reference intensity. Here, the reference intensity is, for example, -70 dBm. In the case where the radio wave intensity is detected in stages (for example, 0 to 5 stages) as in the radio wave display of a smartphone, the reference intensity is, for example, 3 stages. If the air conditioner operation management unit 15 determines that the radio wave intensity of the detected radio wave is equal to or greater than the reference intensity (yes), the process proceeds to step S107. On the other hand, when the air conditioner operation management unit 15 determines that the radio wave intensity of the detected radio wave is not equal to or higher than the reference intensity (no), the process proceeds to step S106.

(step S106)

The air conditioner operation management unit 15 discards or deletes the information of the wireless ID of the wireless communication unit 3 of the indoor unit 2 having the radio wave intensity not satisfying the reference intensity.

Here, when a plurality of radio waves are detected in the process of step S103, the air conditioner operation management portion 15 performs the processes of steps S104 to S106 of the detected radio wave number.

(step S107)

The air conditioner operation management unit 15 associates and registers the radio ID of the radio communication unit 3 of the indoor unit 2 having the radio wave intensity equal to or higher than the reference intensity with the information of the radio wave intensity.

(step S108)

The air conditioner operation management unit 15 transmits an operation start instruction to the wireless communication unit 3 of the indoor unit 2 having the registered wireless ID.

Fig. 6 is a flowchart showing processing performed until the operation of the indoor unit 2 side of the air conditioning system 100 according to embodiment 2 of the present invention is started.

Next, the processing performed until the operation of the indoor unit 2 side of the air conditioning system 100 according to embodiment 2 is started will be described with reference to fig. 6.

(step S201)

The indoor-unit control unit 11 determines whether or not an operation start command is received from the portable terminal unit 6 by using the wireless communication unit 3. When the indoor-unit control unit 11 determines that the operation start command has been received from the portable terminal unit 6 (yes), the process proceeds to step S202. On the other hand, when the indoor unit control unit 11 determines that the operation start command is not received from the portable terminal unit 6 (no), it waits until it is detected.

(step S202)

The indoor unit control unit 11 determines whether or not a person in the air-conditioning target space of the indoor unit 2 is detected by the person detection unit 4. When the indoor unit control unit 11 determines that a person in the air-conditioning target space of the indoor unit 2 is detected (yes), the process proceeds to step S203. On the other hand, when the indoor unit control unit 11 determines that a person in the air-conditioning target space of the indoor unit 2 is not detected (no), the process proceeds to step S201. Here, the reason why the determination as to whether or not the person in the air-conditioning target space of the indoor unit 2 is detected is to exclude the indoor unit 2, in which no person is present in the air-conditioning target space, from the operation target for energy saving. The detection of the person in the air-conditioned space of the indoor unit 2 by the person sensing detection unit 4 may be performed before the measurement of the radio wave intensity is started.

Further, there is also a model that does not include the human sensing detection unit 4, depending on the indoor unit 2. Therefore, in such a case, the determination process of step S202 may not be performed. In this case, when the indoor unit control unit 11 determines that the operation start command from the portable terminal unit 6 is received in the determination of step S201 (yes), the process proceeds to step S203.

(step S203)

The indoor unit control unit 11 starts the operation of the indoor unit 2, and starts the operation of the outdoor unit 5 by transmitting an operation start command to the outdoor unit control unit 14 using the wired communication line unit 7, thereby executing the air conditioning operation.

Fig. 7 is a flowchart showing processing performed until the operation of the indoor unit 2 on the portable terminal unit 6 side of the air conditioning system 100 according to embodiment 2 of the present invention is stopped.

Next, a process until the operation of the indoor unit 2 to be stopped is stopped on the portable terminal unit 6 side in the air conditioning system 100 according to embodiment 2 will be described with reference to fig. 7.

(step S301)

Upon receiving an operation stop input from the air conditioner operation input unit 16, the air conditioner operation management unit 15 reads the wireless ID registered in itself.

(step S302)

The air conditioner operation management unit 15 transmits an operation stop instruction from the portable wireless communication unit 9 to the wireless communication unit 3 of the indoor unit 2 having the read wireless ID.

Note that the operation of changing the setting such as setting the temperature of the indoor unit 2 can be executed by the same processing as the flowchart shown in fig. 7. In this case, in step S302, the command transmitted from the portable wireless communication unit 9 becomes a setting change command or the like.

Fig. 8 is a flowchart showing processing performed until the operation of the indoor unit 2 side of the air conditioning system 100 according to embodiment 2 of the present invention is stopped.

Next, a process performed until the operation of the indoor unit 2 to be stopped in the air conditioning system 100 according to embodiment 2 is stopped will be described with reference to fig. 8.

(step S401)

The indoor-unit control unit 11 determines whether or not an operation stop command is received from the portable terminal unit 6 by using the wireless communication unit 3. When the indoor-unit control unit 11 determines that the operation stop command has been received from the portable terminal unit 6 (yes), the process proceeds to step S402. On the other hand, when the indoor unit control unit 11 determines that the operation stop instruction is not received from the portable terminal unit 6 (no), it waits until it is received.

(step S402)

The indoor unit control unit 11 stops the operation of the indoor unit 2, and stops the operation of the outdoor unit 5 by transmitting an operation stop command to the outdoor unit control unit 14 using the wired communication line unit 7, thereby stopping the air conditioning operation.

As described above, the air conditioning system 100 according to embodiment 2 includes: a plurality of indoor units 2 having a wireless communication unit 3 for emitting radio waves; and a portable terminal unit 6 that performs wireless communication with each wireless communication unit 3. The portable terminal unit 6 detects the radio wave emitted from the wireless communication unit 3, and transmits an operation start command to the wireless communication unit 3 that has emitted the radio wave having the predetermined reference intensity or higher.

According to the air conditioning system 100 of embodiment 2, the portable terminal unit 6 detects the radio wave emitted from the wireless communication unit 3, and transmits an operation start instruction to the wireless communication unit 3 that has emitted the radio wave of the preset reference intensity or higher. That is, the radio wave intensity of the radio wave is correlated with the distance, so that it can be determined that the indoor unit 2 including the radio communication unit 3 which emits the radio wave having a strong radio wave intensity is located closer to the portable terminal unit 6. Therefore, by providing as described above, even in an environment where the position of the indoor unit section 2 frequently changes, the indoor unit section 2 in the vicinity of the user can be easily operated.

In which it is difficult to know whether or not a user can actually operate a certain indoor unit 2. Therefore, the feedback function may be provided in the indoor unit 2 or the portable terminal unit 6. For example, when a light emitting unit such as an LED is provided in the indoor unit 2, the light emitting unit is turned on to give feedback to the user about the operation. The portable terminal unit 6 displays the address of the indoor unit 2 that has received the operation, in addition to the light emission and vibration, and gives feedback to the user about which indoor unit 2 has received the operation, the number of indoor units 2 that have received the operation, and the like.

In the air conditioning system 100 according to embodiment 2, each indoor unit 2 includes a human sensing detection unit 4 that detects a human, and the indoor unit 2 that receives the operation start command via the wireless communication unit 3 starts the operation when the human sensing detection unit 4 detects a human.

According to the air conditioning system 100 of embodiment 2, only the indoor unit 2 in which the human detection unit 4 detects a human starts operating in the indoor unit 2 in which the wireless communication unit 3 receives the operation start command. Therefore, the indoor unit 2 in which no person is present in the air-conditioning target space can be removed from the operation target, and energy saving can be facilitated.

Embodiment 3

Hereinafter, although embodiment 3 of the present invention will be described, descriptions of the same contents as those of

embodiments

1 and 2 will be omitted, and the same reference numerals will be given to the same or corresponding portions as those of

embodiments

1 and 2.

The air conditioning system 100 according to embodiment 3 starts operation of the indoor unit 2 having a radio wave intensity equal to or higher than a preset reference intensity and a radio wave intensity up to the nth upper position. Wherein N is, for example, "3". The setting of N can be freely set by the administrator from the air conditioner operation input unit 16, for example. Note that N may be set by a user other than the administrator.

Fig. 9 is a flowchart showing processing performed until the operation of the indoor unit 2 on the portable terminal unit 6 side of the air conditioning system 100 according to embodiment 3 of the present invention is started.

Next, the processing performed until the operation of the indoor unit 2 on the portable terminal unit 6 side of the air conditioning system 100 according to embodiment 3 is started will be described with reference to fig. 9.

The processing in steps S101 to S106 is the same as that in embodiment 2, and therefore, the description thereof is omitted.

(step S111)

The air conditioner operation management unit 15 compares the registered radio IDs with the radio wave intensity information, and determines whether or not there are radio IDs having the same radio wave intensity or whether or not there are a plurality of radio IDs having radio wave intensities within a preset range. However, this determination is performed when the nth cannot be determined because there are a plurality of wireless IDs in the vicinity of the nth that have the same or similar radio wave intensities. That is, when there are wireless IDs having the same or similar radio wave intensities in the order of being far from the nth except for the nth vicinity, the determination is not performed. If the air conditioner operation management unit 15 determines that there are wireless IDs having the same radio wave intensity or that there are a plurality of wireless IDs having radio wave intensities within a predetermined range (yes), the process proceeds to step S113. On the other hand, if the air conditioner operation management unit 15 determines that there is no radio ID having the same radio wave intensity and there are no plurality of radio IDs having radio wave intensities within a predetermined range (no), the process proceeds to step S112. Here, the radio wave intensity within the predetermined range is, for example, ± 5 dBm. That is, when there are a radio ID having a radio wave intensity of-60 dBm and a radio ID having a radio wave intensity of-55 dBm, it is determined that there are a plurality of radio IDs having radio wave intensities within a predetermined range.

(step S112)

The air conditioner operation management unit 15 sorts the detected radio waves from those having strong radio wave intensity, and registers the radio ID of the wireless communication unit 3 of the indoor unit 2 that has emitted the nth or higher radio wave in association with the information of the radio wave intensity.

(step S113)

The air conditioner operation management unit 15 transmits a radio wave intensity change command for decreasing the output radio wave intensity by a preset value to the radio communication unit 3 of the indoor unit 2 having the radio ID having the same radio wave intensity or having the radio ID having the radio wave intensity within a preset range, and the process proceeds to step S102. Here, as for radio waves, the attenuation amount changes depending on the distance, and radio waves having low wave intensity are liable to have a difference caused by the distance. Therefore, by reducing the radio wave intensity of the radio wave output from the wireless communication section 3, it is easy to determine the difference in distance from the portable terminal section 6 to the indoor unit 2. However, instead of transmitting the radio wave intensity change command for decreasing the radio wave intensity to be output by a preset value, the radio wave intensity change command for increasing the radio wave intensity to be output by a preset value may be transmitted. The information on the change in the radio wave intensity is registered in the air conditioner operation management unit 15. Then, for example, the air conditioner operation management unit 15 transmits an air conditioner operation command and then transmits a radio wave intensity change command to return the radio wave intensity to the original radio wave intensity to the wireless communication unit 3 of the indoor unit 2 having changed the radio wave intensity.

(step S114)

Fig. 10 is a flowchart showing processing performed until the operation of the indoor unit 2 side of the air conditioning system 100 according to embodiment 3 of the present invention is started.

Next, the processing performed until the operation of the indoor unit 2 side of the air conditioning system 100 according to embodiment 3 is started will be described with reference to fig. 10.

(step S211)

The indoor-unit control unit 11 determines whether or not an operation start command is received from the portable terminal unit 6, using the wireless communication unit 3. When the indoor-unit control unit 11 determines that the operation start command from the portable terminal unit 6 is received (yes), the process proceeds to step S214. On the other hand, when the indoor-unit control unit 11 determines that the operation start command from the portable terminal unit 6 has not been received (no), the process proceeds to step S212.

(step S212)

The indoor-unit control unit 11 determines whether or not the radio communication unit 3 has received the radio-wave intensity change command. When the indoor-unit control unit 11 determines that the radio communication unit 3 has received the radio-wave intensity change command (yes), the process proceeds to step S213. On the other hand, if the indoor-unit control unit 11 determines that the radio communication unit 3 has not received the radio-wave intensity change command (no), the process proceeds to step S211.

(step S213)

The indoor-unit control unit 11 decreases the intensity of the radio wave output from the wireless communication unit 3 by a preset value, and proceeds to the process of step S211.

(step S214)

The indoor unit control unit 11 determines whether or not a person in the air-conditioning target space of the indoor unit 2 is detected by the person detection unit 4. When the indoor unit control unit 11 determines that a person in the air-conditioning target space of the indoor unit 2 is detected (yes), the process proceeds to step S215. On the other hand, when the indoor unit control unit 11 determines that a person in the air-conditioning target space of the indoor unit 2 is not detected (no), the process proceeds to step S211.

However, there is also a model that does not include the human sensing detection unit 4, depending on the indoor unit 2. Therefore, in such a case, the determination process of step S214 may not be performed. In this case, when the indoor unit control unit 11 determines that the operation start command from the portable terminal unit 6 is received in the determination of step S211 (yes), the process proceeds to step S215. In embodiment 3, the indoor unit 2 up to the nth highest radio wave intensity is set as an operation target, and the indoor unit 2 from which a person in the air-conditioning target space is not detected is excluded from the operation target. Therefore, there are cases where there are fewer than N indoor units 2 that actually perform air conditioning operation. Therefore, when importance is placed on comfort as compared with energy saving, the process of determining the operating-target indoor units 2 may be repeated until N number of the operating-target indoor units 2 are reached (steps S101 to S114).

(step S215)

As described above, in the air conditioning system 100 according to embodiment 3, the portable terminal unit 6 sorts the detected radio waves from the radio waves having a strong radio wave intensity, and transmits the operation start command to the wireless communication unit 3 that transmits the radio waves of the preset order or more.

According to the air conditioning system 100 of embodiment 3, the portable terminal unit 6 sorts the detected radio waves from the radio waves having a strong radio wave intensity, and transmits an operation start command to the wireless communication unit 3 that emits the radio waves of the preset number of bits or more. Therefore, the conditions for determining the indoor unit 2 to be operated can be customized by the user.

In the air conditioning system 100 according to embodiment 3, when the portable terminal unit 6 detects the same radio wave intensity or radio wave intensities within a plurality of preset ranges, it transmits a radio wave intensity change command to the radio communication unit 3 that transmits radio waves of the same radio wave intensity or radio wave intensities within the preset ranges. In addition, the wireless communication section 3 that has received the radio wave intensity change instruction reduces the radio wave intensity of the emitted radio wave.

According to the air conditioning system 100 of embodiment 3, when the portable terminal unit 6 detects the same radio wave intensity or detects radio wave intensities within a plurality of predetermined ranges, it transmits a radio wave intensity change command to the wireless communication unit 3 that transmits a radio wave of the radio wave intensity. Therefore, the sequence of distances from each indoor unit 2 to the portable terminal unit 6 can be determined with high accuracy.

Embodiment 4

Hereinafter, although embodiment 4 of the present invention will be described, descriptions of the same parts as those in embodiments 1 to 3 will be omitted, and the same reference numerals will be given to the same or corresponding parts as those in embodiments 1 to 3.

The air conditioning system 100 according to embodiment 4 performs a process of easily selecting an indoor unit 2 in which a person is present in an air-conditioned space as an operation target.

Fig. 11 is a flowchart showing processing performed until the operation of the indoor unit 2 side of the air conditioning system 100 according to embodiment 4 of the present invention is started.

Next, the processing performed until the operation of the indoor unit 2 side of the air conditioning system 100 according to embodiment 4 is started will be described with reference to fig. 11.

(step S221)

The indoor unit control unit 11 determines whether or not a person in the air-conditioning target space of the indoor unit 2 is detected by the person detection unit 4. When the indoor unit control unit 11 determines that a person in the air-conditioning target space of the indoor unit 2 is detected (yes), the process proceeds to step S222. On the other hand, when the indoor unit control unit 11 determines that a person in the air-conditioning target space of the indoor unit 2 is not detected (no), the process proceeds to step S223.

(step S222)

The indoor unit control unit 11 increases the intensity of the radio wave output from the wireless communication unit 3 by a preset value. This is because the indoor unit 2 in which a person is present in the air-conditioned space can be easily selected as the operation target by increasing the intensity of the radio wave output from the wireless communication unit 3. However, when the radio wave intensity outputted from the radio communication unit 3 has been increased by a preset value, the process is skipped.

(step S223)

When the radio wave intensity output from the radio communication unit 3 has been increased by a preset value, the indoor unit control unit 11 returns the radio wave intensity output from the radio communication unit 3 to the original value. This is to prevent the indoor unit 2 in which no person is present in the air-conditioning target space from being easily selected as the operation target.

(step S224)

The indoor-unit control unit 11 determines whether or not an operation start command is received from the portable terminal unit 6 by using the wireless communication unit 3. When the indoor-unit control unit 11 determines that the operation start command from the portable terminal unit 6 is received (yes), the process proceeds to step S225. On the other hand, when the indoor-unit control unit 11 determines that the operation start command from the portable terminal unit 6 has not been received (no), the process proceeds to step S221.

(step S225)

As described above, in the air conditioning system 100 according to embodiment 4, when the human detection section 4 detects a human, the indoor unit 2 increases the radio wave intensity of the radio wave emitted by the wireless communication section 3.

According to the air conditioning system 100 of embodiment 4, when the human detection sensing unit 4 detects a human, the indoor unit 2 increases the radio wave intensity of the radio wave emitted by the wireless communication unit 3. Therefore, the indoor unit 2 in which a person is present in the air-conditioning target space can be easily selected as the operation target. However, the processing of increasing the radio wave intensity of the radio wave emitted by the wireless communication unit 3 when the human detection unit 4 detects a human is effective also in the case where the indoor unit 2 up to the nth is not found in embodiment 2.

Embodiment 5

Although embodiment 5 of the present invention will be described below, descriptions of the same parts as those in embodiments 1 to 4 will be omitted, and the same reference numerals will be given to the same or corresponding parts as those in embodiments 1 to 4.

The air conditioning system 100 according to embodiment 5 performs a process of easily selecting an indoor unit 2 in which a person is present in an air-conditioned space as an operation target, as in embodiment 4.

Fig. 12 is a flowchart showing processing performed until the operation of the indoor unit 2 on the portable terminal unit 6 side of the air conditioning system 100 according to embodiment 5 of the present invention is started.

Next, the processing of the air conditioning system 100 according to embodiment 5 until the operation of the indoor unit 2 is started on the portable terminal unit 6 side will be described with reference to fig. 12.

The processing in steps S101 to S108 is the same as that in embodiment 2, and therefore, the description thereof is omitted.

(step S121)

The air conditioner operation management unit 15 determines whether or not the portable radio communication unit 9 has received the radio wave intensity change command. Here, as will be described later, the radio wave intensity change command is transmitted to facilitate selection of the indoor unit 2, in which a person in the air-conditioned space is detected by the person detection unit 4, as an operation target. When the air conditioner operation management unit 15 determines that the portable radio communication unit 9 has received the radio wave intensity change command (yes), the process proceeds to step S122. On the other hand, when the air conditioner operation management unit 15 determines that the portable-side wireless communication unit 9 has not received the radio wave intensity change instruction (no), the process proceeds to step S105.

(step S122)

The air conditioner operation management unit 15 confirms the radio ID of the radio communication unit 3 of the sender of the radio wave intensity change command, transmits the radio wave intensity change command for reducing the output radio wave intensity by a preset value to the radio communication unit 3 of the indoor unit 2 other than the indoor unit 2 having the radio ID, and proceeds to the process of step S102.

Fig. 13 is a flowchart showing processing performed until the operation of the indoor unit 2 side of the air conditioning system 100 according to embodiment 5 of the present invention is started.

Next, the processing performed until the operation of the indoor unit 2 side of the air conditioning system 100 according to embodiment 5 is started will be described with reference to fig. 13.

(step S231)

The indoor unit control unit 11 determines whether or not a person in the air-conditioning target space of the indoor unit 2 is detected by the person detection unit 4. When the indoor unit control unit 11 determines that a person in the air-conditioning target space of the indoor unit 2 is detected (yes), the process proceeds to step S232. On the other hand, when the indoor unit control unit 11 determines that a person in the air-conditioning target space of the indoor unit 2 is not detected (no), the process proceeds to step S233.

(step S232)

The indoor unit control unit 11 transmits a radio wave intensity change command for reducing the radio wave intensity output from the radio communication unit 3 of the other indoor unit 2 by a preset value to the portable radio communication unit 9. This is because the intensity of the radio wave output from the radio communication unit 3 of the other indoor unit 2 is reduced, and the intensity of the radio wave output from the radio communication unit 3 of the indoor unit 2 is relatively increased, so that the indoor unit 2 in which a person is present in the space to be air-conditioned can be easily selected as the object to be operated. However, when a radio wave intensity change command for reducing the radio wave intensity output from the wireless communication unit 3 of the other indoor unit 2 has been transmitted, the process is skipped.

(step S233)

When a radio wave intensity change command for reducing the radio wave intensity output from the radio communication unit 3 of another indoor unit 2 has been transmitted, the indoor unit control unit 11 transmits a radio wave intensity change command for returning the radio wave intensity output from the radio communication unit 3 of another indoor unit 2 to the original radio wave intensity to the portable-side radio communication unit 9. This is to prevent the indoor unit 2 in which no person is present in the air-conditioning target space from being easily selected as the operation target.

(step S234)

The indoor-unit control unit 11 determines whether or not an operation start command is received from the portable terminal unit 6, using the wireless communication unit 3. When the indoor-unit control unit 11 determines that the operation start command from the portable terminal unit 6 is received (yes), the process proceeds to step S235. On the other hand, when the indoor-unit control unit 11 determines that the operation start command from the portable terminal unit 6 has not been received (no), the process proceeds to step S236.

(step S235)

(step S236)

The indoor-unit control unit 11 determines whether or not the radio communication unit 3 has received the radio-wave intensity change command. When the indoor-unit control unit 11 determines that the radio communication unit 3 has received the radio-wave intensity change command (yes), the process proceeds to step S237. On the other hand, if the indoor-unit control unit 11 determines that the radio communication unit 3 has not received the radio-wave intensity change command (no), the process proceeds to step S231.

(step S237)

The indoor unit control unit 11 determines whether or not a person in the air-conditioning target space of the indoor unit 2 is detected by the person detection unit 4. When the indoor unit control unit 11 determines that a person in the air-conditioning target space of the indoor unit 2 is detected (yes), the process proceeds to step S231. On the other hand, when the indoor unit control unit 11 determines that a person in the air-conditioning target space of the indoor unit 2 is not detected (no), the process proceeds to step S238.

(step S238)

The indoor-unit control unit 11 decreases the intensity of the radio wave output from the wireless communication unit 3 by a preset value, and proceeds to the process of step S231.

As described above, in the air conditioning system 100 according to embodiment 5, when the human detection section 4 detects a human, the indoor unit 2 transmits a radio wave intensity change command to the portable terminal unit 6. When receiving the radio intensity change command, the portable terminal unit 6 transmits the radio intensity change command to the wireless communication unit 3 other than the transmitter of the radio intensity change command.

According to the air conditioning system 100 of embodiment 5, when receiving the radio intensity change command, the portable terminal unit 6 transmits the radio intensity change command to the wireless communication unit 3 other than the transmitter of the radio intensity change command. In this way, the intensity of the radio wave output from the wireless communication unit 3 of the indoor unit 2 other than the indoor unit 2 in which the human sensing detection unit 4 detects a human is reduced, and the intensity of the radio wave output from the wireless communication unit 3 of the human sensing detection unit is relatively increased. This makes it possible to easily select the indoor unit 2 in which a person is present in the air-conditioned space as the operation target.

Embodiment 6

Although embodiment 6 of the present invention will be described below, descriptions of the same parts as those in embodiments 1 to 5 will be omitted, and the same reference numerals will be given to the same or corresponding parts as those in embodiments 1 to 5.

Fig. 14 is a flowchart showing processing performed until the operation of the indoor unit 2 on the portable terminal unit 6 side of the air conditioning system 100 according to embodiment 6 of the present invention is started. Fig. 15 is a diagram illustrating a process of excluding the indoor unit 2 having the flight address from the operation target in the air conditioning system 100 according to embodiment 6 of the present invention. Here, the "enclave address" refers to an address that is not adjacent to another address among the plurality of addresses. As shown in fig. 15, the enclave address is valid when set according to a certain rule such that columns are english letters and rows are numbers.

Next, the processing of the air conditioning system 100 according to embodiment 6 until the operation of the indoor unit 2 is started on the portable terminal unit 6 side will be described with reference to fig. 14 and 15.

The processing in steps S101 to S103, S107, and S108 is the same as that in embodiment 2, and therefore, the description thereof is omitted.

(step S131)

The air conditioner operation management unit 15 confirms the wireless ID of the wireless communication unit 3 of the sender and the address of the wireless communication unit 3 of the sender, and starts measurement of the radio wave intensity (RSSI). Also, the air conditioner operation management portion 15 resets the measurement of the time from the start of the radio wave detection. Here, the air conditioner operation management unit 15 determines the radio wave intensity of the detected radio wave by using an average or median value based on the measurement results of a plurality of times in order to determine the fluctuation of the radio wave intensity.

(step S132)

The air conditioner operation management unit 15 determines whether or not the radio wave intensity of the detected radio wave determined in the process of step S131 is equal to or higher than a preset reference intensity. If the air conditioner operation management unit 15 determines that the radio wave intensity of the detected radio wave is equal to or greater than the reference intensity (yes), the process proceeds to step S133. On the other hand, when the air conditioner operation management unit 15 determines that the radio wave intensity of the detected radio wave is not equal to or greater than the reference intensity (no), the process proceeds to step S134.

(step S133)

The air conditioner operation management unit 15 determines whether or not the address of the wireless communication unit 3 of the indoor unit 2 is an address of the enclave. If the air conditioner operation management unit 15 determines that the address of the wireless communication unit 3 of the indoor unit 2 is the address of the enclave (yes), the process proceeds to step S134. On the other hand, when the air conditioner operation management unit 15 determines that the address of the wireless communication unit 3 of the indoor unit 2 is not the address of the enclave (no), the process proceeds to step S107.

(step S134)

The air conditioner operation management unit 15 discards information of radio wave intensity not satisfying the reference intensity or the radio ID of the radio communication unit 3 of the indoor unit 2 having the flight address.

Here, as shown in fig. 15, for example, the addresses of the wireless communication units 3 of the indoor units 2 having the radio wave intensities equal to or higher than the preset reference intensity (-70dBm or higher) are "1-a", "2-a", and "2-E", respectively. In this case, "1-a" and "2-a" are addresses adjacent to each other, but the address of "2-E" is not adjacent to the addresses of "1-a" and "2-a" and becomes an enclave address. Therefore, in this case, the wireless ID of the wireless communication unit 3 of the indoor unit 2 having the address of "2-E" is excluded from the operation target. This is to avoid erroneous detection of the radio wave intensity by the air conditioner operation management unit 15 due to the influence of an obstacle or the like. That is, the air conditioner operation management unit 15 may detect that the radio wave intensity of the radio wave emitted from the wireless communication unit 3 of the indoor unit 2 located far from the portable terminal unit 6 is stronger than the radio wave intensity of the wireless communication unit 3 of the indoor unit 2 located near the portable terminal unit 6. Therefore, in the processing of steps S133 and S134, the radio ID of the radio communication unit 3 of the indoor unit 2 having the flight address is excluded from the operation target as described above, so that erroneous detection of the radio wave intensity can be avoided. Wherein, can also constitute: the wireless ID is associated with the position of the indoor unit 2, and the radio wave intensity is prevented from being erroneously detected based on the wireless ID instead of the address.

Here, in the case where a plurality of radio waves are detected in the process of step S103, the air conditioner operation management section 15 performs the processes of steps S131 to S134 of the detected radio wave number.

As described above, in the air conditioning system 100 according to embodiment 6, the portable terminal unit 6 acquires the address of the wireless communication unit 3 that has emitted a radio wave of a predetermined reference intensity or higher. The portable terminal unit 6 excludes the wireless communication unit 3 having the enclave address from the object to which the operation start command is transmitted.

According to the air conditioning system 100 of embodiment 6, since the wireless communication unit 3 having the flight address is excluded from the objects to which the operation start command is transmitted, erroneous detection of the radio wave intensity can be avoided.
