[0009] [Figure 1] This is a schematic diagram showing the air conditioning system according to Embodiment 1. [Figure 2] This is a functional block diagram showing the air conditioning system according to Embodiment 1. [Figure 3] This is a diagram illustrating the method of connecting a terminal device and a remote controller according to Embodiment 1. [Figure 4] This is a hardware configuration diagram showing the control device of the terminal device according to Embodiment 1. [Figure 5] This flowchart shows the control method for the air conditioning system according to Embodiment 1. [Modes for carrying out the invention]

[0010] Embodiment 1. The air conditioning system 100 according to Embodiment 1 will be described below with reference to the drawings. Figure 1 is a schematic diagram showing the air conditioning system 100 according to Embodiment 1. As shown in Figure 1, the air conditioning system 100 includes air conditioning units 1a to 1d, remote controllers 2a to 2d, environmental sensors 3a to 3d, and a terminal device 4. Each component of the air conditioning system 100 is installed, for example, in the same room. In Figure 1, four air conditioning units 1a to 1d, remote controllers 2a to 2d, and environmental sensors 3a to 3d are shown as an example, but the number of these units may be two, three, or five or more. Furthermore, these do not have to be installed in the same room. In addition, Figure 1 shows only the indoor units of the air conditioning units 1a to 1d, and the outdoor units are omitted.

[0011] Air conditioning unit 1a is a device that provides air conditioning to the air-conditioned space Sa within the room's interior space where air conditioning unit 1a is installed. The configuration, arrangement, and function of air conditioning units 1b, 1c, and 1d are the same as those of air conditioning unit 1a. In other words, air conditioning units 1b to 1d are devices that provide air conditioning to the air-conditioned spaces Sb to Sd within the room's interior space where air conditioning units 1b to 1d are installed. Hereafter, when air conditioning units 1a to 1d are not distinguished, they will simply be referred to as air conditioning unit 1.

[0012] The remote controller 2a is wired to a corresponding air conditioning unit 1a among multiple air conditioning units 1, and controls the air conditioning unit 1a. The wiring connecting the remote controller 2a and the air conditioning unit 1a is hidden, for example, behind a wall, so the user cannot see the connection between the remote controller 2a and the air conditioning unit 1a. The user can operate the remote controller 2a to confirm a unique ID or other identifier that distinguishes the remote controller 2a from other remote controllers 2b to 2d.

[0013] The configuration, arrangement, and function of remote controllers 2b to 2d are the same as those of remote controller 2a. In other words, remote controllers 2b to 2d are wired to their corresponding air conditioning units 1b to 1d among the multiple air conditioning units 1, and control the air conditioning units 1b to 1d. Hereafter, when remote controllers 2a to 2d are not distinguished, they will simply be referred to as remote controller 2. Multiple remote controllers 2 may be installed in locations unrelated to the corresponding air-conditioned space, such as being clustered together on a wall in a room. Note that the remote controllers 2 and the air conditioning units 1 may be connected wirelessly.

[0014] The environmental sensor 3a measures the environmental conditions of the air-conditioned space Sa in which it is installed. Environmental conditions include, for example, temperature, humidity, CO2 concentration, or PM2.5 concentration in the air-conditioned space Sa. The environmental sensor 3a also communicates wirelessly with a corresponding remote controller 2a among multiple remote controllers 2 to transmit information indicating the measured environmental conditions to the remote controller 2a. Communication between the environmental sensor 3a and the remote controller 2a is performed using wireless LAN such as Wi-Fi (registered trademark; hereinafter omitted) or Bluetooth (registered trademark; hereinafter omitted). The environmental sensor 3a is installed in the air-conditioned space Sa in a position that can be changed. Specifically, the environmental sensor 3a is installed in the air-conditioned space Sa, excluding the space above the ceiling. Furthermore, the environmental sensor 3a is, for example, a freestanding or wall-mounted type, is portable, and its installation position can be easily changed by the user. However, the environmental sensor 3a is positioned closer to the corresponding air conditioning unit 1a than the other environmental sensors 3b to 3d.

[0015] The configuration, arrangement, and function of environmental sensors 3b to 3d are the same as those of environmental sensor 3a. In other words, environmental sensors 3b to 3d are installed under the same conditions as environmental sensor 3a and measure the environmental conditions of the air-conditioned spaces Sb to Sd in which they are installed. Hereafter, when environmental sensors 3a to 3d are not distinguished, they will simply be referred to as environmental sensor 3. Environmental sensor 3 corresponds to the "specific means" in this disclosure.

[0016] Terminal device 4 is, for example, a smartphone, tablet, or PC terminal owned by user U. Terminal device 4 has an application installed for operating the air conditioning unit 1. Hereinafter, the application for operating the air conditioning unit 1 will be referred to as the air conditioning app. The air conditioning app enables terminal device 4 to control the air conditioning unit 1, which is linked to the remote controller 2, via the remote controller 2. Terminal device 4 communicates wirelessly 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, the air conditioner 1, the remote controller 2, and the environmental sensor 3 correspond to each other on a one-to-one basis. The linking of these devices is determined at the time of installation of the air conditioner 1, the remote controller 2, and the environmental sensor 3. The air conditioning system 100 identifies the target controller linked to the air conditioner 1 that the user wishes to operate without going through the user's settings when the user desires to operate the air conditioner 1 closest to the user. That is, in Embodiment 1, the target controller is the remote controller 2 linked to the air conditioner 1 closest to the user. The user can operate the air conditioner 1 closest to the user via the target controller.

[0018] Note that the air conditioning system 100 may have a system controller for integrally controlling the air conditioner 1.

[0019] FIG. 2 is a functional block diagram showing the air conditioning system 100 according to Embodiment 1. 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 includes a display unit (not shown) and an operation unit (not shown). The display unit is, for example, a liquid crystal screen and displays the operation content of the air conditioner 1 linked to the remote controller 2. The operation content includes the presence or absence of operation of the air conditioner 1, the operation mode, the set temperature, the indoor temperature, the wind direction, and the air volume. The operation unit is, for example, a physical button and can input the operation content for the air conditioner 1 linked to the remote controller 2. The operation content includes the start and stop of the operation of the air conditioner 1, and the change of the operation mode, the set temperature, the wind direction, and the air 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 conditioner 1. The control device 22 also generates a first advertisement signal and instructs the communication device 23 to transmit the first advertisement signal to the terminal device 4. The first advertisement signal includes identification information indicating the remote controller 2 that transmits the information, and identification information of the environmental sensor 3 associated with the remote controller 2 that transmits the information. The identification information is unique to the remote controller 2 and the environmental sensor 3, and is, for example, the BD address or unique ID of the equipment.

[0021] The communication device 23 transmits an operation signal to the corresponding air conditioner 1 based on instructions from the control device 22. Similarly, when the communication device 23 receives an operation signal from the terminal device 4, it transmits it to the corresponding air conditioner 1. Furthermore, when the communication device 23 receives environmental information (described later) from the environmental sensor 3, it transmits it to the corresponding air conditioner 1. The communication device 23 also transmits a first advertisement signal to the terminal device 4. The first advertisement signal is transmitted periodically. In addition, the communication device 23 of each remote controller 2 transmits the first advertisement signal with the same intensity.

[0022] The environmental sensor 3 comprises an environmental measuring device 31, a control device 32, and a communication device 33. The environmental measuring device 31 measures the environmental conditions in the air-conditioned space. The control device 32 generates environmental information indicating the measured environmental conditions and instructs the communication device 33 to transmit this environmental information to the remote controller 2. The control device 32 also generates a second advertisement signal and instructs the communication device 33 to transmit the second advertisement signal to the terminal device 4. The second advertisement 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 accordance with instructions from the control device 32. The communication device 33 also transmits a second advertisement signal to the terminal device 4. The second advertisement signal is transmitted periodically. Furthermore, the communication device 33 of each environmental sensor 3 transmits the second advertisement signal with the same intensity.

[0024] The terminal device 4 includes 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 conditioner 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 entered from the operation screen. The control device 42 then generates an operation signal indicating the operation content entered from the operation screen and instructs the communication device 43 to transmit the operation signal to the remote controller 2, which has been identified as the target controller.

[0025] The control device 42 determines the target controller based on the first and second advertisement signals. A specific method of connecting the terminal device 4 and the remote controller 2 will be explained using Figure 3. Figure 3 is a diagram illustrating the method of connecting the terminal device 4 and the remote controller 2 according to Embodiment 1. First, the control device 42 determines that the environmental sensor 3 indicated by the second advertisement signal received with the highest intensity among the second advertisement signals received by the communication device 43 is the target sensor associated with the target controller, and stores the identification information of this target sensor. This utilizes the principle that the intensity of radio waves weakens as the distance from the source increases. That is, as described above, since the communication device 33 of each environmental sensor 3 transmits the second advertisement signal with the same intensity, the higher the intensity of the received radio wave, the more likely it is to be a radio wave transmitted from an environmental sensor 3 located closer to the terminal device 4. The intensity of the received radio wave is, for example, RSSI (Received Signal Strength Indicator) [dBm]. The target sensor corresponds to the "purpose identification means" in this disclosure.

[0026] Next, the control device 42 searches for a first advertisement signal containing the identification information of the target sensor among the first advertisement signals received by the communication device 43. When a first advertisement signal containing the target identification information is found, the control device 42 determines that the remote controller 2 indicated by this first advertisement 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 unit 1 and is located near the environmental sensor 3, the target controller identified by the above means becomes the device associated with the air conditioning unit 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 unit 1 via the target controller.

[0027] For example, in the example shown in Figure 3, first, the terminal device 4 receives the second advertisement signal with the highest intensity from environmental sensor 3c among the multiple environmental sensors 3. The size of the arrow corresponds to the strength of the radio waves received by the terminal device 4. Here, the second advertisement signal from environmental sensor 3 contains the identification information of environmental sensor 3c, which is "AA:BB:CC". Therefore, next, the terminal device 4 searches for the first advertisement signal among the multiple remote controllers 2 that contains the information "AA:BB:CC" as the identification information of environmental sensor 3c. At this time, the terminal device 4 finds that the first advertisement signal transmitted from the remote controller 2c associated with environmental sensor 3c contains the information "AA:BB:CC" as the identification information of environmental sensor 3c. The terminal device 4 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 conditioner 1c via the remote controller 2c.

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

[0029] Figure 4 is a hardware configuration diagram showing the control device 42 of the terminal device 4 according to Embodiment 1. The control device 42 has a processor 101 such as a CPU and memory 102. Each function of the control device 42 is realized by the processor 101 and memory 102. Figure 4 shows that the processor 101 and memory 102 are connected to each other so as to be able to communicate via a bus 103.

[0030] The air conditioning application is written as a program and stored in memory 102. The processor 101 reads and executes the air conditioning application stored in memory 102, thereby realizing the functions of the control device 42. The control device 22 of the remote controller 2 and the control device 32 of the environmental sensor 3 also consist of a processor and memory, similar to the control device 42 of the terminal device 4.

[0031] Figure 5 is a flowchart illustrating the control method for the air conditioning system 100 according to Embodiment 1. First, the communication device 23 of the remote controller 2 transmits a first advertisement signal (step S1), and the communication device 33 of the environmental sensor 3 transmits a second advertisement signal (step S2). However, the first advertisement signal and the second advertisement signal are transmitted periodically and may be transmitted simultaneously, or the second advertisement signal may be transmitted first.

[0032] When the communication device 43 of the terminal device 4 receives the first advertisement signal and the second advertisement signal, the control device 42 of the terminal device 4 determines the second advertisement signal with the highest intensity (step S3). Next, the control device 42 of the terminal device 4 identifies the remote controller 2 associated with the environmental sensor 3 that emitted the second advertisement signal with the highest intensity 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 Embodiment 1 has multiple identification means linked to multiple remote controllers 2, and the target controller is identified using the identification means. Therefore, the air conditioning system 100 allows the user to easily operate the air conditioning device 1 they desire.

[0034] Furthermore, the environmental sensor 3 of the air conditioning system 100 in Embodiment 1 is installed in a position that can be changed within the space to be air-conditioned. Therefore, even if a user retrofits the environmental sensor 3 to enable operation by the terminal device 4 when, for example, only the air conditioning unit 1 is already installed, the installation of the terminal device 4 can be easily done without any construction work. Thus, the air conditioning system 100 in Embodiment 1 can be easily constructed by the user.

[0035] Furthermore, the air conditioning system 100 of Embodiment 1 can be configured by introducing only relatively inexpensive remote controllers 2 and environmental sensors 3 to an existing air conditioning device 1, thereby reducing costs and construction man-hours.

[0036] Furthermore, conventional terminal devices that do not communicate with the environmental sensor 3 cannot identify the nearest air conditioning unit 1. Moreover, when multiple remote controllers 2 are arranged together on a wall in a room, the remote controllers 2 may be positioned independently of the location of the air conditioning unit 1, making it impossible for the terminal device to identify the remote controller 2 associated with the nearest air conditioning unit 1. As a result, the user had to search for the remote controller 2 to operate the air conditioning unit 1 closest to them and then confirm the identification information of that remote controller 2. To obtain 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 cumbersome for the user.

[0037] In this regard, the air conditioning system 100 of Embodiment 1 uses an environmental sensor 3 provided in conjunction with the air conditioning unit 1 to automatically recognize the identification information of the remote controller 2 for operating the air conditioning unit 1 closest to the user in the terminal device 4. Therefore, the user can operate the air conditioning unit 1 closest to them on the spot. For example, in an office that employs a free-address system where employees work at different desks each day, and the air conditioning unit 1 that the user wants to use also changes each 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 first embodiment of the air conditioning system 100, the air conditioner 1 is controlled based on the environmental conditions measured by the environmental sensor 3. Here, since the environmental sensor 3 is located in the space to be air-conditioned, it can measure environmental conditions that are more in line with the environment in which the user is spending time, compared to sensors installed inside the air conditioner 1 or the remote controller 2. For example, even if the temperature near the user's seat is locally higher than the average room temperature due to heat exhaust from office equipment, the air conditioner 1 is controlled based on the temperature measured by the environmental sensor 3. Therefore, in such cases, the air conditioner 1 in the space to be air-conditioned where the user is spending time can lower the temperature of the blown air or increase the airflow compared to other air conditioners 1. In this way, the first embodiment of the air conditioning system 100 can improve the accuracy of air conditioning and further enhance user comfort.

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

[0040] However, the environmental sensor 3 can be placed anywhere in the air-conditioned space, as long as it is positioned closer to the corresponding air conditioning unit 1 than other environmental sensors 3. For example, by placing the environmental sensor 3 closer to the user, the user's comfort can be further improved, as already explained. Also, by placing the environmental sensor 3 closer to the air conditioning unit 1, such as by directly attaching it to the air conditioning unit 1, the possibility of operating an air conditioning unit 1 other than the one the user intends to operate can be reduced.

[0041] The above describes the embodiments of the present disclosure, but the present disclosure is not limited to the configuration of the embodiments described above, and various modifications or combinations are possible within the scope of its technical idea. For example, the environmental sensor 3 may be replaced with another small digital device having wireless communication capabilities. Alternatively, a beacon or the like having only wireless communication capabilities may be used. In these cases as well, in the air conditioning system 100 of Embodiment 1, the identification information of the remote controller 2 for operating the air conditioning unit 1 closest to the user can be automatically recognized by the terminal device 4, similar to the environmental sensor 3.

[0042] Alternatively, a sticker or the like with a two-dimensional code printed on it may be used instead of or in addition to the environmental sensor 3. The two-dimensional code may be, for example, a QR code (registered trademark) and indicate the identification information of the remote controller 2. Therefore, a medium with a two-dimensional code printed on it also corresponds to the "identification means" in this disclosure. The sticker with the two-dimensional code printed on it is placed in the space to be air-conditioned and its installation location can be changed. Specifically, for example, it is affixed to the main body of the air conditioning unit 1 linked to the remote controller 2 or to a desk or the like near the air conditioning unit 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, as the target controller, can control the air conditioning unit 1 via the remote controller 2 indicated by the acquired identification information. Note that if a sticker or the like with a two-dimensional code printed on it 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 form described above. For example, the terminal device 4 may identify the target controller as follows: First, the environmental sensor 3 is made 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 made to transmit the information to the terminal device 4 by including identification information indicating the environmental sensor 3 that transmits the information, and identification information of the remote controller 2 associated with the environmental sensor 3 that transmits the information, in the second advertisement signal. In this case as well, the terminal device 4 can identify the target controller based on the identification information of the remote controller 2 indicated by the second advertisement signal received with the highest intensity among the second advertisement signals received from the environmental sensor 3.

[0044] Furthermore, the terminal device 4 may be configured to only be able to operate the air conditioning unit 1 when the radio wave strength exceeds a threshold. The threshold is, for example, the lowest strength obtainable when the terminal device 4 is in the room. In this case, the air conditioning system 100 can improve security by restricting operation by third parties who should not be operating the air conditioning unit 1.

[0045] Furthermore, when the terminal device 4 receives the second advertisement signal from the environmental sensor 3, it may also receive not only the identification status but also the environmental status measured by the environmental sensor 3. In this case, for example, the measured temperature, humidity, CO2 concentration, or PM2.5 concentration may be displayed on the operation screen of the terminal device 4. In this case, the user can use the displayed information as a reference when operating the air conditioning system 1.

[0046] Furthermore, if the terminal device 4 receives multiple signals of the same intensity from the environmental sensor 3, it may display an option on the operation screen of the terminal device 4 to select which air conditioning unit 1 to operate. However, the terminal device 4 may also operate multiple air conditioning units 1. [Explanation of symbols]
