[0003] Japanese Patent Application Laid-Open No. 2020-134163

[0004] In general, there are cases where multiple remote controllers linked to each air conditioning apparatus are provided, and a specific air conditioning apparatus is controlled via the remote controller. In this case, even if an electromagnetic wave transmitter is provided as in the air conditioning system of Patent Document 1, the user cannot identify the remote controller linked to the air conditioning apparatus to be operated among the multiple remote controllers. Therefore, when multiple remote controllers linked to each air conditioning apparatus are provided, it is not easy for the user to operate the desired air conditioning apparatus.

[0005] The present disclosure has been made to solve the above-mentioned problems, and aims to provide an air conditioning system and a control method for an air conditioning system that allows a user to easily operate the air conditioning device of their choice.

[0006] The air conditioning system of the present disclosure comprises a plurality of air conditioning devices that condition the space to be air-conditioned, a plurality of remote controllers each linked to the plurality of air conditioning devices, and a plurality of identification means each linked to the plurality of remote controllers, and a target controller, which is one of the plurality of remote controllers identified using the identification means, controls the air conditioning device linked to the target controller based on an operation signal input from a terminal device.

[0007] The control method for an air conditioning system according to the present disclosure is a control method for an air conditioning system comprising a plurality of air conditioning devices that condition the space to be air-conditioned, a plurality of remote controllers each linked to the plurality of air conditioning devices, and a plurality of identification means each linked to the plurality of remote controllers, and comprises the steps of identifying one of the plurality of remote controllers as a target controller using the identification means, and controlling the air conditioning device linked to the target controller based on an operation signal input from a terminal device via the target controller.

[0008] The air conditioning system has a plurality of specifying means each associated with a plurality of remote controllers, and the target controller is specified using the specifying means. Therefore, in the air conditioning system, the user can easily operate the air conditioner of their choice.

It is a functional block diagram showing an air conditioning system according to embodiment 1.

It is a hardware configuration diagram showing a control device of the terminal device according to embodiment 1. It is a flowchart showing a control method of the air conditioning system according to embodiment 1.

[0010] Embodiment 1. An air conditioning system 100 according to Embodiment 1 will be described below with reference to the drawings. FIG. 1 is a schematic diagram showing the configuration of the air conditioning system 100 according to Embodiment 1. As shown in FIG. 1, the air conditioning system 100 includes air conditioners 1a to 1d, remote controllers 2a to 2d, environmental sensors 3a to 3d, and a terminal device 4. Each device in the air conditioning system 100 is installed in, for example, the same room. Note that FIG. 1 illustrates four air conditioners 1a to 1d, remote controllers 2a to 2d, and environmental sensors 3a to 3d, but the number of these devices may be two, three, five, or more. Furthermore, these devices do not necessarily have to be installed in the same room. Furthermore, FIG. 1 shows only the indoor units of the air conditioners 1a to 1d, and omits the outdoor units.

[0011] Air conditioner 1a is a device that conditions the air of the air-conditioned space Sa in which air conditioner 1a is installed, among the indoor spaces of a room. Air conditioners 1b, 1c, and 1d have the same configuration, arrangement, and functions as air conditioner 1a. In other words, air conditioners 1b to 1d are devices that condition the air of the air-conditioned spaces Sb to Sd in which air conditioners 1b to 1d are installed, among the indoor spaces of a room. Hereinafter, when there is no need to distinguish between air conditioners 1a to 1d, they will be simply referred to as air conditioner 1.

[0012] The remote controller 2a is connected by wire to a corresponding air conditioning device 1a among the multiple air conditioning devices 1, and controls the air conditioning device 1a. The wiring connecting the remote controller 2a to the air conditioning device 1a is hidden, for example, behind a wall, and the user cannot visually confirm the connection between the remote controller 2a and the air conditioning device 1a. The user can operate the remote controller 2a to check a unique ID and the like that distinguishes the remote controller 2a from the other remote controllers 2b to 2d.

[0013] The configuration, arrangement, and functions of the remote controllers 2b to 2d are similar to those of the remote controller 2a. That is, the remote controllers 2b to 2d are connected by wire to the corresponding air conditioners 1b to 1d among the multiple air conditioners 1, and control the air conditioners 1b to 1d. Hereinafter, when there is no need to distinguish between the remote controllers 2a to 2d, they will be simply referred to as the remote controller 2. The multiple remote controllers 2 may be provided in locations unrelated to the corresponding air-conditioned spaces, such as being arranged together on a wall in a room. Note that the remote controller 2 and the air conditioner 1 may also be connected wirelessly.

[0014] The environmental sensor 3a measures the environmental condition of the air-conditioned space Sa in which the environmental sensor 3a is installed. The environmental condition includes, for example, the temperature, humidity, CO ２ The environmental sensor 3a wirelessly communicates with a corresponding remote controller 2a among the multiple remote controllers 2, transmitting information indicating the measured environmental condition to the remote controller 2a. Communication between the environmental sensor 3a and the remote controller 2a is performed via a wireless LAN such as Wi-Fi (registered trademark; omitted below) or Bluetooth (registered trademark; omitted below). The environmental sensor 3a is installed in a position that can be changed in the air-conditioned space Sa. Specifically, the environmental sensor 3a is installed in the air-conditioned space Sa excluding the ceiling space in the room. The environmental sensor 3a is, for example, a freestanding or wall-mounted type, and is portable, allowing the user to easily change its installation position. However, the environmental sensor 3a is installed closer to the corresponding air conditioning device 1a than the other environmental sensors 3b to 3d.

[0015] The configuration, arrangement, and functions of the environmental sensors 3b to 3d are also similar to those of the environmental sensor 3a. In other words, the environmental sensors 3b to 3d are installed under the same conditions as the environmental sensor 3a, and measure the environmental conditions of the air-conditioned spaces Sb to Sd in which they are installed. Hereinafter, when there is no need to distinguish between the environmental sensors 3a to 3d, they will be simply referred to as the environmental sensor 3. The environmental sensor 3 corresponds to the "identification means" in this disclosure.

[0016] The terminal device 4 is, for example, a device such as a smartphone, tablet, or PC terminal owned by the user U. An application for operating the air conditioning apparatus 1 is installed on the terminal device 4. Hereinafter, the application for operating the air conditioning apparatus 1 will be referred to as an air conditioning app. The air conditioning app causes the terminal device 4 to realize a function for controlling the air conditioning apparatus 1 linked to the remote controller 2 via the remote controller 2. The terminal device 4 wirelessly communicates with the remote controller 2 and the environmental sensor 3, for example, using a wireless LAN such as Wi-Fi or a communication standard such as Bluetooth.

[0017] As described above, there is a 1:1:1 correspondence between the air conditioning apparatus 1, the remote controller 2, and the environmental sensor 3. The association of these devices is determined when the air conditioning apparatus 1, the remote controller 2, and the environmental sensor 3 are installed. When a user wishes to operate the air conditioning apparatus 1 closest to them, the air conditioning system 100 identifies the target controller associated with the air conditioning apparatus 1 that the user wishes to operate, without any settings by the user. In other words, in the first embodiment, the target controller is the remote controller 2 associated with the air conditioning apparatus 1 closest to the user. The user can operate the air conditioning apparatus 1 closest to them via the target controller.

[0018] The air conditioning system 100 may also have a system controller that performs integrated control of the air conditioning device 1 .

[0019] FIG. 2 is a functional block diagram showing the air conditioning system 100 pertaining to the first embodiment. As shown in FIG. 2, the remote controller 2 has an operation / display device 21, a control device 22, and a communication device 23. The operation / display device 21 comprises a display unit (not shown) and an operation unit (not shown). The display unit is, for example, an LCD screen, and displays the operation details of the air conditioning apparatus 1 linked to the remote controller 2. The operation details include whether the air conditioning apparatus 1 is operating, the operation mode, the set temperature, the indoor temperature, the airflow direction, and the airflow volume. The operation unit is, for example, a physical button, and can input operation details for the air conditioning apparatus 1 linked to the remote controller 2. The operation details include starting and stopping the operation of the air conditioning apparatus 1, and changing the operation mode, the set temperature, the airflow direction, and the airflow volume.

[0020] The control device 22 generates an operation signal indicating the operation content input from the operation display device 21, and instructs the communication device 23 to send this operation signal to the air conditioning device 1. The control device 22 also generates a first advertising signal, and instructs the communication device 23 to transmit the first advertising signal to the terminal device 4. The first advertising signal includes identification information indicating the remote controller 2 that transmits the information, and identification information of the environmental sensor 3 linked to the remote controller 2 that transmits the information. The identification information is information unique to the remote controller 2 and the environmental sensor 3, and is, for example, the BD address or unique ID of the device.

[0021] The communication device 23 transmits an operation signal to the corresponding air conditioning device 1 in response to an instruction from the control device 22. Similarly, when the communication device 23 receives an operation signal from the terminal device 4, it transmits the operation signal to the corresponding air conditioning device 1. Furthermore, when the communication device 23 receives environmental information (described later) from the environmental sensor 3, it transmits the environmental information to the corresponding air conditioning device 1. The communication device 23 also transmits a first advertising signal to the terminal device 4. The first advertising signal is transmitted periodically. Furthermore, the communication devices 23 of all remote controllers 2 transmit the first advertising signal with equal strength.

[0022] The environmental sensor 3 has an environmental measuring device 31, a control device 32, and a communication device 33. The environmental measuring device 31 measures the environmental state in the space to be air-conditioned. The control device 32 generates environmental information indicating the measured environmental state and instructs the communication device 33 to transmit this environmental information to the remote controller 2. The control device 32 also generates a second advertising signal and instructs the communication device 33 to transmit the second advertising signal to the terminal device 4. The second advertising signal includes identification information of the environmental sensor 3 that transmits the information.

[0023] The communication device 33 transmits environmental information to the corresponding remote controller 2 in response to an instruction from the control device 32. The communication device 33 transmits a second advertising signal to the terminal device 4. The second advertising signal is transmitted periodically. In addition, the communication devices 33 of all the environmental sensors 3 transmit the second advertising signal with the same intensity.

[0024] The terminal device 4 has an operation display device 41, a control device 42, and a communication device 43. The operation display device 41 is, for example, a touch panel. The control device 42 displays an operation screen for operating the air conditioning device 1 on the operation display device 41. The control device 42 also controls the content displayed on the operation screen based on the operation content input from the operation screen. The control device 42 then generates an operation signal indicating the operation content input from the operation screen and instructs the communication device 43 to transmit the operation signal to the remote controller 2 identified as the target controller.

[0025] The control device 42 determines the target controller based on the first advertising signal and the second advertising signal. A specific connection method between the terminal device 4 and the remote controller 2 will be described with reference to FIG. 3 . FIG. 3 is a diagram for explaining the connection method between the terminal device 4 and the remote controller 2 according to the first embodiment. First, the control device 42 determines the environmental sensor 3 indicated by the second advertising signal received with the highest strength among the second advertising signals received by the communication device 43 as the target sensor associated with the target controller, and stores the identification information of this target sensor. This utilizes the principle that the strength of radio waves decreases the farther the distance from the source of transmission. That is, since the communication devices 33 of all environmental sensors 3 transmit second advertising signals with the same strength as described above, it can be determined that the higher the strength of the received radio waves, the radio waves transmitted from the environmental sensor 3 located closer to the terminal device 4. The strength of the received radio wave is, for example, a received signal strength indicator (RSSI) [dBm]. The purpose sensor corresponds to the "purpose specifying means" in the present disclosure.

[0026] Next, the control device 42 searches for a first advertising signal including identification information of the target sensor among the first advertising signals received by the communication device 43. When a first advertising signal including the target identification information is found, it determines that the remote controller 2 indicated by this first advertising signal is the target controller, and stores the identification information indicating this remote controller 2. As described above, since the environmental sensor 3 corresponds to the air conditioning device 1 and is provided near the environmental sensor 3, the target controller identified by the above means is the device linked to the air conditioning device 1 closest to the user. Then, the terminal device 4 establishes communication with the target controller based on the identification information indicating the target controller, and transmits an operation signal to the air conditioning device 1 via the target controller.

[0027] For example, in the example of FIG. 3 , the terminal device 4 first receives the second advertising signal with the highest strength from the environmental sensor 3c among the multiple environmental sensors 3. Note that the size of the arrow corresponds to the level of radio wave strength when received by the terminal device 4. Here, the second advertising signal from the environmental sensor 3 contains the identification information of the environmental sensor 3c, "AA:BB:CC." Therefore, the terminal device 4 then searches for a first advertising signal that contains the information "AA:BB:CC" as the identification information of the environmental sensor 3c among the first advertising signals transmitted from the multiple remote controllers 2. At this time, the terminal device 4 finds that the first advertising signal transmitted from the remote controller 2c linked to the environmental sensor 3c contains the information "AA:BB:CC" as the identification information of the environmental sensor 3c. The terminal device 4 then stores the identification information "XX:YY:ZZ" transmitted by the remote controller 2c as the identification information of the target controller, connects to the remote controller 2c based on this identification information, and transmits an operation signal to the air conditioning device 1c via the remote controller 2c.

[0028] When the air conditioning device 1 receives an operation signal from the remote controller 2, it performs an operation based on the operation content indicated by the received operation signal and the environmental state indicated by the environmental information.

[0029] 4 is a hardware configuration diagram showing the control device 42 of the terminal device 4 according to the first embodiment. The control device 42 has a processor 101 such as a CPU and a memory 102. Each function of the control device 42 is realized by the processor 101 and the memory 102. FIG. 4 shows that the processor 101 and the memory 102 are connected to each other via a bus 103 so as to be able to communicate with each other.

[0030] The air conditioning application is written as a program and stored in memory 102. The processor 101 implements the functions of the control device 42 by reading and executing the air conditioning application stored in memory 102. Note that, like the control device 42 of the terminal device 4, the control device 22 of the remote controller 2 and the control device 32 of the environmental sensor 3 also comprise a processor and memory.

[0031] 5 is a flowchart showing a control method for the air conditioning system 100 according to the first embodiment. First, the communication device 23 of the remote controller 2 transmits a first advertising signal (step S1), and the communication device 33 of the environmental sensor 3 transmits a second advertising signal (step S2). However, the first advertising signal and the second advertising signal are each transmitted periodically, and may be transmitted simultaneously, or the second advertising signal may be transmitted first.

[0032] When the communication device 43 of the terminal device 4 receives the first advertising signal and the second advertising signal, the control device 42 of the terminal device 4 determines which second advertising signal has the strongest intensity (step S3). Subsequently, the control device 42 of the terminal device 4 identifies the remote controller 2 linked to the environmental sensor 3 that transmitted the strongest second advertising signal as the target controller (step S4). Then, the control device 42 of the terminal device 4 transmits an operation signal to the target controller (step S5).

[0033] As described above, the air conditioning system 100 of the first embodiment has a plurality of specifying means linked to a plurality of remote controllers 2, respectively, and the target controller is specified using the specifying means. Therefore, in the air conditioning system 100, the user can easily operate the air conditioner 1 desired.

[0034] Furthermore, the environmental sensor 3 of the air conditioning system 100 of the first embodiment is installed in a position that can be changed in the air-conditioned space. Therefore, even if the user wants to add the environmental sensor 3 later to accommodate operation by the terminal device 4 when only the air conditioning apparatus 1 is already installed, the installation of the terminal device 4 can be easily performed without any construction work. Therefore, the air conditioning system 100 of the first embodiment can be easily constructed by the user.

[0035] Furthermore, the air conditioning system 100 of embodiment 1 can be constructed by introducing only a relatively inexpensive remote controller 2 and an environmental sensor 3 into an existing air conditioning device 1, thereby reducing costs and construction labor.

[0036] Furthermore, conventional terminal devices that do not communicate with the environmental sensor 3 are unable to identify the air conditioning apparatus 1 that is located closest to them. Furthermore, when multiple remote controllers 2 are placed together on a wall in a room, the remote controllers 2 may be placed regardless of the location of the air conditioning apparatus 1, and therefore the terminal device is unable to identify the remote controller 2 that is linked to the air conditioning apparatus 1 that is located closest to them. For this reason, the user had to search for the remote controller 2 that can operate the air conditioning apparatus 1 closest to them and then check the identification information of this remote controller 2. To know the identification information of the remote controller 2, the user had to operate the operation display device 21 of the remote controller 2, which was time-consuming for the user.

[0037] In this regard, the air conditioning system 100 of embodiment 1 uses an environmental sensor 3 provided corresponding to each air conditioning unit 1 to have the terminal device 4 automatically recognize the identification information of the remote controller 2 for operating the air conditioning unit 1 closest to the user. Therefore, the user can operate the air conditioning unit 1 closest to them on the spot. For example, even in an office with a free address system where work desks vary from day to day, and the air conditioning unit 1 that a user wants to use changes from day to day, the user does not need to search for the remote controller 2 or check its identification information each time. In this way, the air conditioning system 100 of embodiment 1 improves the convenience of using the air conditioning unit 1.

[0038] Furthermore, in the air conditioning system 100 of the first embodiment, the air conditioning device 1 is controlled based on the environmental condition measured by the environmental sensor 3. Because the environmental sensor 3 is located in the air-conditioned space, it can measure the environmental condition in line with the user's environment by comparing it with sensors installed inside the air conditioning device 1 or the remote controller 2. For example, even if the temperature near the user's seat is locally higher than the average indoor temperature due to heat exhaust from office equipment, the air conditioning device 1 is controlled based on the temperature measured by the environmental sensor 3. Therefore, in such a case, the air conditioning device 1 in the air-conditioned space where the user is located can lower the temperature of the air blown out and increase the airflow rate compared to other air conditioning devices 1. In this way, the air conditioning system 100 of the first embodiment can improve the accuracy of air conditioning and further enhance user comfort.

[0039] Furthermore, in the air conditioning system 100 of the first embodiment, the target controller is identified by the environmental sensor 3. Since the installation position of the environmental sensor 3 can be changed, if the environmental sensor 3 is installed at a lower position than the air conditioning device 1 installed at a high position on the ceiling or wall, the distance to the terminal device 4 will be closer. Therefore, the distance for each environmental sensor 3 can be estimated with higher accuracy.

[0040] However, the environmental sensor 3 may be placed anywhere in the air-conditioned space, as long as it is placed closer to the corresponding air conditioning apparatus 1 than other environmental sensors 3. For example, placing the environmental sensor 3 closer to the user can further improve user comfort, as already explained. Furthermore, placing the environmental sensor 3 closer to the air conditioning apparatus 1, such as by directly attaching it to the air conditioning apparatus 1, can reduce the possibility of operating an air conditioning apparatus 1 other than the one the user wants to operate.

[0041] The above is a description of the embodiments of the present disclosure, but the present disclosure is not limited to the configurations of the above embodiments and various modifications or combinations are possible within the scope of the technical concept. For example, other small digital devices with wireless communication capabilities may be provided instead of the environmental sensor 3. Also, beacons or the like that have only wireless communication capabilities may be used. In these cases, in the air conditioning system 100 of embodiment 1, as with the environmental sensor 3, the terminal device 4 can automatically recognize the identification information of the remote controller 2 for operating the air conditioning apparatus 1 closest to the user.

[0042] Alternatively, a sticker or the like having a two-dimensional code printed thereon may be used instead of or in addition to the environmental sensor 3. The two-dimensional code, such as a QR code (registered trademark), indicates the identification information of the remote controller 2. Therefore, a medium on which the two-dimensional code is printed also corresponds to the "identification means" of the present disclosure. The sticker with the two-dimensional code printed thereon is provided in the air-conditioned space and can be relocated. Specifically, for example, it is affixed to the main body of the air conditioning apparatus 1 linked to the remote controller 2 or to a desk or the like near the air conditioning apparatus 1. The two-dimensional code is read by the terminal device 4 using the camera function of the terminal device 4. As a result, the terminal device 4 can acquire the identification information indicated by the two-dimensional code and control the air conditioning apparatus 1 as the target controller via the remote controller 2 indicated by the acquired identification information. Note that if a sticker or the like having a two-dimensional code printed thereon is used instead of the environmental sensor 3, the environmental sensor 3 can be omitted.

[0043] Furthermore, the procedure by which the terminal device 4 identifies the target controller is not limited to the above-described form. For example, the terminal device 4 may identify the target controller as follows. First, the environmental sensor 3 is caused to acquire identification information of the corresponding remote controller 2. This process may be performed when the environmental sensor 3 is installed. Then, the environmental sensor 3 is caused to transmit a second advertising signal to the terminal device 4, with the second advertising signal including identification information indicating the environmental sensor 3 that transmits the information and identification information of the remote controller 2 linked to the environmental sensor 3 that transmits the information. In this case, too, the terminal device 4 can identify the target controller based on the identification information of the remote controller 2 indicated by the second advertising signal received with the highest strength from the environmental sensor 3.

[0044] Furthermore, the terminal device 4 may be configured to be able to operate the air conditioning apparatus 1 only when the radio wave strength exceeds a threshold. The threshold is, for example, the lowest strength that can be obtained when the terminal device 4 is present in a room. In this case, the air conditioning system 100 can restrict operation of the air conditioning apparatus 1 by third parties who should not operate it, thereby improving security.

[0045] Furthermore, when receiving the second advertising signal from the environmental sensor 3, the terminal device 4 may receive not only the identification state but also the environmental state measured by the environmental sensor 3. At this time, for example, the measured temperature, humidity, CO ２ In this case, the user can use the displayed information as a reference when operating the air conditioning apparatus 1.

[0046] Furthermore, when the terminal device 4 receives multiple signals of the same intensity from the environmental sensor 3, the terminal device 4 may display an option on the operation screen of the terminal device 4 for selecting which air conditioning device 1 to operate. However, the terminal device 4 may also be configured to operate multiple air conditioning devices 1.
