The display unit 43 is an output interface that displays various information. The storage unit 44 stores various information. The CPU 45 controls the entire terminal device 7.

FIG. 5 is an explanatory diagram showing an example of a notification screen related to a program update on the display unit 43 of the terminal device 7. As shown in FIG. When the adapter 3 determines that there is an update program that will cause the air conditioning system 1 to stop, the display unit 43 of the terminal device 7 shown in FIG. 5 switches from the program update confirmation screen 43A to the update time OFF screen 43B. When the display unit 43 detects an ON operation specifying the update time, it switches from the update time OFF screen 43B to the update time ON screen 43C. The program update confirmation screen 43A is a screen that notifies the user of the terminal device 7 that a new version of the program update is being confirmed. The update time OFF screen 43B is a screen that notifies the user of the terminal device 7 of program update guide information 431 when automatic updates are OFF. The guidance information 431 includes "The air conditioner cannot be used during the update. Please specify the time when the air conditioner will not be used as the start time." The update time OFF screen 43B includes an update time switching button 432 for switching between an update time ON screen 43C for specifying an update time or an update time OFF screen 43B, and an update button 433 for instructing a program update. The user of the terminal device 7 can instruct the adapter 3 to update the program via the communication network 8 by operating the update button 433.

The update time ON screen 43C is a screen that notifies the user of the terminal device 7 of the automatic update time and program update guide information when the automatic update is ON. The update time ON screen 43C includes an update time switching button 432, an update button 433, and a designation button 434 for specifying the update time. The user of the terminal device 7 can freely set the program update start time by operating the designation button 434. Thereby, by starting to stop the air conditioning system 1 due to a program update, for example, while the user is away, it is possible to prevent the user from feeling uncomfortable. The set update start time of the program is sent to the adapter 3 by touching the update button 434.

Next, the operation of the air conditioning system 1 of this embodiment will be explained. FIG. 6 is a flowchart showing an example of the processing operation of the CPU 14 in the adapter 3 related to update notification processing. In FIG. 6, the second acquisition unit 26 in the CPU 14 in the adapter 3 executes an update download process shown in FIG. 7, which will be described later (step S11). After executing the update download process, the determination unit 27 in the CPU 14 determines whether or not the program update requires stopping the air conditioning system 1 among the multiple types of program updates (step S12). Note that program updates include programs that require the air conditioning system 1 to be stopped and programs that do not need to be accompanied by the air conditioning system 1 to be updated. Programs that do not require stopping the air conditioning system 1 are, for example, update programs for the learning model, the firmware of the adapter 3, the firmware of the edge, and the like. For programs that do not require stopping the air conditioning system 1, for example, it is necessary to stop the movement of the fan or wind deflector that can be felt by the user, so it is ideal for updating the learning model, adapter 3 firmware, edge firmware, etc. This is a program that does not stop the air conditioning system 1 itself, since the air conditioning system 1 itself cannot be controlled anymore, but the air conditioning system 1 can continue as it was before the update.

If the program update requires stopping the air conditioning system 1 (Step S12, Yes), the notification unit 28 in the CPU 14 notifies the user's terminal device 7 that the program can be updated with the specified update time (Step S13). ), the processing operation shown in FIG. 6 ends. As a result, the terminal device 7 displays the update time ON screen 43C or the update time OFF screen 43B shown in FIG. 5 based on the notification that the program can be updated with the update time specified. Then, the user can recognize whether the program has been updated by looking at the display screen, and can specify a desired update time by operating the designation button 434.

If the program update does not need to involve stopping the air conditioning system 1 (step S12, No), the determination unit 27 ends the processing operation shown in FIG. 6 without notifying the user. As a result, the user can automatically update the program without performing a program update operation.

As explained above, the adapter 3 determines whether the program update needs to involve stopping the air conditioning system 1. If the program update requires stopping the air conditioning system 1, the adapter 3 notifies the user's terminal device 7 that the program can be updated at a specified update time. The terminal device 7 displays the update time ON screen 43C or the update time OFF screen 43B based on the notification that the program can be updated with the update time specified. As a result, the user can see the display screen and recognize whether the program has been updated with an update time specified, and can also freely specify the update time by operating the designation button 434. For example, if a time period during which the user is not present is specified as the update time, it is possible to avoid a situation where the update of the control program that involves stopping the air conditioning system 1 causes discomfort to the user.

FIG. 7 is a flowchart showing an example of the processing operation of the CPU 14 in the adapter 3 related to update download processing. In FIG. 7, the second acquisition unit 26 in the CPU 14 in the adapter 3 determines whether the version information of the current program has been acquired from the indoor unit 2 (step S21).

When the second acquisition unit 26 acquires the version information of the current program from the indoor unit 2 (Step S21, Yes), the second acquisition unit 26 determines whether or not the version information of the update program has been acquired from the server device 5 (Step S22). . When the second acquisition unit 26 acquires the version information of the update program from the server device 5 (Step S22, Yes), it determines whether the version information of the update program is newer (Step S23).

If the version information of the update program is newer (Step S23, Yes), the receiving unit 23 determines that there is an update program, starts downloading the update program from the server device 5 (Step S24), and performs the process shown in FIG. Finish the operation.

If the second acquisition unit 26 does not acquire the version information of the current program from the indoor unit 2 (Step S21, No), or if it does not acquire the version information of the update program from the server device 5 (Step S22, No). ), the processing operation shown in FIG. 7 ends.

If the version information of the update program is not newer (step S23, No), the second acquisition unit 26 determines that the version information of the current program is newer or the same version information, and ends the processing operation shown in FIG. .

As explained above, the adapter 3 compares the version information of the current program from the indoor unit 2 and the version information of the update program from the server device 5, and if the version information of the update program is newer, the adapter 3 updates the update program. Start downloading. As a result, the adapter 3 can recognize the presence or absence of a downloadable update program.

FIG. 8 is a flowchart showing an example of the processing operation of the CPU 14 in the adapter 3 related to the update time setting process. In FIG. 8, the second acquisition unit 26 in the CPU 14 in the adapter 3 determines whether a program update time has been detected from the user's terminal device 7 (step S31). Note that the terminal device 7 notifies the adapter 3 of the update time specified by operating the designation button 434 on the update time ON screen 43C or the update time OFF screen 43B shown in FIG. When the second acquisition unit 26 detects the program update time from the user's terminal device 7 (step S31, Yes), the second acquisition unit 26 sets the program update time (step S32), and ends the processing operation shown in FIG. do. As a result, the update unit 29 in the CPU 14 determines whether or not the current time is the set program update time, and if the current time is the set program update time, starts the program update operation. Become. If the update time of the program is not detected from the user's terminal device 7 (step S31, No), the update unit 29 sets the current time as the update time (step S33), and ends the processing operation shown in FIG. do. As a result, the update unit 29 immediately starts updating the program without asking the user for confirmation.

As explained above, when the adapter 3 detects the program update time from the terminal device 7, it sets the program update time. If the current time is the program update time, the adapter 3 starts the program update operation. As a result, the user of the terminal device 7 can freely set the update time of the program. For example, if a time period during which the user is not present is specified as the update time, it is possible to avoid a situation where the update of the control program that involves stopping the air conditioning system 1 causes discomfort to the user.

FIG. 9 is a flowchart showing an example of the processing operation of the CPU 14 in the adapter 3 related to update processing. The update unit 29 in the CPU 14 determines whether the program update time is set in the second acquisition unit 26 in the CPU 14 in the adapter 3 (step S41). If the program update time is set (Step S41, Yes), the update unit 29 determines whether the current time is the program update time (Step S42).

When the current time is the program update time (step S42, Yes), the update unit 29 stops the air conditioning system 1 (step S43), updates the control program of the air conditioning system 1 (step S44), and performs the process shown in FIG. The indicated processing operation ends.

If the program update time has not been set (step S41, No), the update unit 29 ends the processing operation shown in FIG. 9 . If the current time is not the program update time (step S42, No), the update unit 29 returns to the process of step S42 to determine whether the current time is the program update time.

As explained above, the adapter 3 can stop the air conditioning system 1 and update the control program of the air conditioning system 1 when the current time is the program update time. As a result, for example, if a time period during which the user is not present is specified as the update time, it is possible to avoid a situation where the update of the control program that involves stopping the air conditioning system 1 causes discomfort to the user.

When the adapter 3 of this embodiment receives a program update notification from the server device 5, it determines whether it is necessary to stop the indoor unit 2 due to the program update. The adapter 3 notifies the user's terminal device 7 of a program update when it is necessary to stop the indoor unit 2. As a result, the user of the terminal device 7 can recognize a program update that requires stopping the indoor unit 2.

The adapter 3 acquires a program update instruction from the terminal device 7 along with the program update time, stops the indoor unit 2 at the update time according to the instruction from the terminal device 7, and causes the indoor unit 2 to execute the program update. As a result, the user of the terminal device 7 can update the program at the desired update time, thereby preventing discomfort caused by an unintended stoppage of the indoor unit 2 due to the program update. In other words, the user can update the program (stop the air conditioning system 1) at a time of his/her own preference, for example, at a time when the user is not present, so that the user will not feel uncomfortable. Furthermore, when the air conditioning system can be updated without stopping the air conditioning system, the update is performed without asking the user, and the user can always enjoy comfort through optimal control.

In this embodiment, the control program for the air conditioning system 1 is, for example, the program for the indoor unit 2, but the program for the adapter 3, the program for the control unit 2B that controls the indoor unit 2, and the program for controlling the indoor unit 2 A learning model or the like may be used, and can be changed as appropriate.

For example, when updating the program of the control unit 2B of the indoor unit 2, the content to be learned may be changed, and in this case, only the learning that the indoor unit 2 can handle can be performed to suppress the capacity of the learning model.

Furthermore, an example is shown in which the user of the terminal device 7 specifies the update time using the designation button 434 on the update time ON screen or the update time OFF screen, and sets the specified update time in the adapter 3. However, if the update time is specified in the previous designation operation of the designation button 434, the update time specified in the previous designation operation may be set in the adapter 3 even without the designation button 434. It can be changed as appropriate.

In this embodiment, the indoor unit 2 itself must be stopped while the program of the indoor unit 2 is being updated, and conditioned air cannot be delivered to the user, so a case where the user is required to specify the update time is exemplified. did. However, this is not limited to the program for the indoor unit 2; for example, if the indoor unit 2 needs to be stopped using another program, the user is contacted. For example, even if there is only one memory area to store the learning model and the learning model cannot be referenced during updating, the user may be allowed to specify the update time, which can be changed as appropriate.

Further, each component of each part shown in the drawings does not necessarily have to be physically configured as shown in the drawings. In other words, the specific form of dispersion/integration of each part is not limited to what is shown in the diagram, but all or part of it may be functionally or physically distributed/integrated in arbitrary units depending on various loads, usage conditions, etc. can be configured.

Furthermore, various processing functions performed in each device can be performed in whole or in part on a CPU (Central Processing Unit) (or a microcomputer such as an MPU (Micro Processing Unit) or an MCU (Micro Controller Unit)). You may also choose to execute it. Further, various processing functions may be executed in whole or in part on a program that is analyzed and executed by a CPU (or a microcomputer such as an MPU or MCU) or on hardware using wired logic. Needless to say.
