[0008] (Findings that formed the basis of this disclosure) At the time the inventors arrived at the idea of this disclosure, there was a technology in place that transmitted product number information stored in a memory unit of an indoor or outdoor unit of an air conditioner to a remote control via a communication line and stored in the remote control, and if an abnormality occurred in the indoor or outdoor unit, displayed the product number information of the abnormal indoor or outdoor unit on the remote control. This allows the product number information of the abnormal device to be confirmed on the remote control, enabling the abnormal device to be inspected and repaired quickly.

[0009] However, when the control board of the target device is designed to be shared among a plurality of devices with different part numbers, when replacing the failed control board, the part number information corresponding to the target device is not stored in the storage unit of the control board in the initial state after replacement. Therefore, the operator who replaces the control board needs to write the part number information corresponding to the target device into the storage unit of the replaced control board. Also, it is conceivable that the part number information written in the storage unit of the control board of the target device is incorrect at the time of shipment from the factory. In this case, it is necessary to change the part number information stored in the storage unit to the correct part number information. And when the installation location is, for example, the ceiling like the indoor unit of the air conditioner, and the workability when changing the part number information stored in the storage unit of the control board is poor, there is a disadvantage that the work is difficult. The inventors discovered the problem of avoiding such a disadvantage, and in order to solve that problem, they came to constitute the subject matter of the present disclosure. Therefore, the present disclosure provides a remote operation system that can facilitate the maintenance of a control board provided in a target device remotely operated by a remote controller.

[0010] Hereinafter, embodiments will be described in detail with reference to the drawings. However, a more detailed description than necessary may be omitted. For example, a detailed description of already well-known matters, or a redundant description of substantially the same configuration may be omitted. This is to avoid making the following description overly redundant and to facilitate the understanding of those skilled in the art. Note that the accompanying drawings and the following description are provided for those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0011] (Embodiment) Hereinafter, embodiments will be described with reference to FIGS. 1 to 6. [1. Configuration of Remote Operation System] Referring to FIG. 1, the configuration of the remote control system 1 in the present disclosure will be described. The remote control system 1 is an air conditioning system including a first outdoor unit 10a, a second outdoor unit 10b, a first indoor unit 20a, a second indoor unit 20b, a third indoor unit 20c, a ventilation device 30, and a remote controller 50.

[0012] The first outdoor unit 10a, the second outdoor unit 10b, the first indoor unit 20a, the second indoor unit 20b, the third indoor unit 20c, and the ventilation device 30 correspond to the target devices of the present disclosure, are connected to the remote controller 50 by a communication cable, and are remotely controlled by the remote controller 50. The first outdoor unit 10a, the second outdoor unit 10b, the first indoor unit 20a, the second indoor unit 20b, and the third indoor unit 20c are connected by refrigerant pipes (not shown) to form a refrigeration cycle. By supplying refrigerant from the first outdoor unit 10a and the second outdoor unit 10b to the first indoor unit 20a, the second indoor unit 20b, and the third indoor unit 20c through the refrigerant pipes, air conditioning of the areas where the first indoor unit 20a, the second indoor unit 20b, and the third indoor unit 20c are installed is performed. The ventilation device 30 performs ventilation of the area where the ventilation device 30 is installed.

[0013] The first outdoor unit 10a includes a control board 11a that controls the operation of the first outdoor unit 10a. The control board 11a has a processor, a memory, a communication interface, etc., and controls the operation of the first outdoor unit 10a by the processor reading and executing a program for controlling the first outdoor unit 10a stored in the memory. Further, the control board 11a includes a rewritable non-volatile first memory 12a. The first memory 12a is, for example, an EEPROM (Electrically Erasable Programmable Read-Only Memory).

[0014] The first memory 12a stores part number information indicating the part number (product number) of the first outdoor unit 10a. In FIG. 1, as shown in the blowout B1, an example is illustrated where the address (communication address) of the first outdoor unit 10a is set to "1-1" and "A" is stored as the part number information in the first memory 12a. Here, the control board 11a is shared among outdoor units with a plurality of different part numbers, and the control board 11a sets control conditions for the first outdoor unit 10a according to the part number information of the first outdoor unit 10a stored in the first memory 12a.

[0015] Similarly, the second outdoor unit 10b includes a control board 11b that controls the operation of the second outdoor unit 10b. The specification of the control board 11b is the same as that of the control board 11a. As shown in the blowout B2, the address of the second outdoor unit 10b is set to "1-2", and "B" is stored as the part number information in the first memory 12b of the control board 11b. The control board 11b sets control conditions for the second outdoor unit 10b according to the part number information of the second outdoor unit 10b stored in the first memory 12b.

[0016] Next, the first indoor unit 20a includes a control board 21a that controls the operation of the first indoor unit 20a. The control board 21a has a processor, a memory, a communication interface, etc., and controls the operation of the first indoor unit 20a by reading and executing the control program of the first indoor unit 20a stored in the memory by the processor. Also, the control board 21a includes a rewritable non-volatile first memory 22a. The first memory 22a is, for example, an EEPROM.

[0017] The first memory 22a stores model number information indicating the model number (product number) of the first indoor unit 20a. As shown in balloon B3, Fig. 1 illustrates a case in which the address (communications address) of the first indoor unit 20a is set to "2-1" and "C" is stored as model number information in the first memory 22a. Here, the control board 21a is shared by indoor units with multiple model numbers having different specifications, and the control board 21a sets control conditions for the first indoor unit 20a according to the model number information of the first indoor unit 20a stored in the first memory 22a.

[0018] Similarly, the second indoor unit 20b is equipped with a control board 21b that controls the operation of the second indoor unit 20b. The specifications of the control board 21b are the same as those of the control board 21a. As shown in speech bubble B4, the address of the second indoor unit 20b is set to "2-2," and "D" is stored as the product number information in the first memory 22b of the control board 21b. The control board 21b sets the control conditions for the second indoor unit 20b according to the product number information of the second indoor unit 20b stored in the first memory 22b.

[0019] Similarly, the third indoor unit 20c is equipped with a control board 21c that controls the operation of the third indoor unit 20c. The specifications of the control board 21c are the same as those of the control board 21a. As shown in speech bubble B5, the address of the third indoor unit 20c is set to "2-3," and "E" is stored as the product number information in the first memory 22c of the control board 21c. The control board 21c sets the control conditions for the third indoor unit 20c according to the product number information of the third indoor unit 20c stored in the first memory 22c.

[0020] Next, the ventilation device 30 is equipped with a control board 31 that controls the operation of the ventilation device 30. The control board 31 has a processor, memory, a communication interface, etc., and controls the operation of the ventilation device 30 by reading and executing a program for controlling the ventilation device 30 that is stored in the memory. The control board 31 also has a non-rewritable first memory 32. The first memory 32 is, for example, a ROM (Read Only Memory).

[0021] The first memory 32 stores model number information indicating the model number (product number) of the ventilation device 30. As shown in speech bubble B6, Fig. 1 illustrates a case where the address (communication address) of the ventilation device 30 is set to "3-1" and "F" is stored as the model number information in the first memory 32. The control board 31 is used in ventilation devices with the same specifications and does not need to accommodate changes in the control conditions, so the model number information stored in the first memory 32 cannot be changed.

[0022] Here, the first memories 12a, 12b, 22a, 22b, 22c, and 32 correspond to the first storage unit of the present disclosure. In the following, when describing matters common to the control boards 11a, 11b, 21a, 21b, 21c, and 31, they will be referred to as control boards without reference numerals. Furthermore, when describing matters common to the first memories 12a, 12b, 22a, 22b, 22c, and 32, they will be referred to as first memories without reference numerals.

[0023] Next, the remote control 50 has a processor, memory, a communication interface, etc., and remotely controls each target device by loading and executing a control program for the remote control 50 stored in the memory by the processor. The remote control 50 has a display unit 51, an up button 52, a down button 53, a left button 54, a right button 55, an enter button 56, a back button 57, and a second memory 58. Information about each target device is stored in the second memory 58, as described below. The second memory 58 corresponds to the second storage unit in this disclosure.

[0024] [2.Storing part number information] 2, the following describes the procedure for the remote control 50 to communicate with each target device (first outdoor unit 10a, second outdoor unit 10b, first indoor unit 20a, second indoor unit 20b, third indoor unit 20c, and ventilation device 30), acquire product number information of each target device, and store the information in the second memory 58. The remote control 50 executes the process according to the flowchart in FIG. 2 when the remote control system 1 is powered on (when the remote control system 1 is installed, when maintenance of the remote control system 1 is performed, etc.).

[0025] The remote controller 50 individually executes the processing according to the flowchart shown in FIG. 2 for each target device. Here, the case where the remote controller 50 acquires the product number information stored in the first memory 12a of the first outdoor unit 10a from the first outdoor unit 10a and stores it in the second memory 58 will be described.

[0026] In step S1 of FIG. 2, the remote controller 50 transmits product number request information to the first outdoor unit 10a. In step S20, when the first outdoor unit 10a (more specifically, the control board 11a) receives the product number request information transmitted from the remote controller 50, the process proceeds to step S21. In step S21, the first outdoor unit 10a transmits the product number information stored in the first memory 12a to the remote controller 50.

[0027] Here, when information other than the product number (such as master unit / slave unit information) is stored in the first memory 12a, the first outdoor unit 10a also transmits the information to the remote controller 50. Further, when the control board 11a is replaced, since a dummy product number is stored in the first memory 12a or it is in a blank state where no product number information is stored, the first outdoor unit 10a transmits information indicating the dummy product number information or the blank state to the remote controller 50.

[0028] In step S2, when the remote controller 50 receives the product number information from the first outdoor unit 10a, the process proceeds to step S3. In step S3, as shown in FIG. 4, the remote controller 50 stores the received product number information in the second memory 58 for each target device. FIG. 4 shows a model information table 60 in which product number information is acquired from each target device in the state illustrated in FIG. 1 and stored in the second memory 58. In the model information table 60 shown in FIG. 4, for each target device, address, product number information, and master unit / slave unit information are stored. For the ventilation device 30, information indicating that the product number cannot be changed is stored.

[0029] [3. Countermeasure processing when the control board is replaced and when the product number information is inappropriate] According to the flowchart shown in FIG. 3, the corresponding processing when the control board of the target device is replaced and when the part number information stored in the first memory of the control board is inappropriate will be described.

[0030] In step S5 of FIG. 3, the remote controller 50 recognizes the presence or absence of the target device whose control board has been replaced by communicating with each target device. Specifically, when the part number information acquired from the target device by communication is dummy part number information or information indicating that the part number information is blank, the remote controller 50 recognizes that the control board has been replaced. Then, when the remote controller 50 recognizes the target device whose control board has been replaced, the process proceeds to step S10, and when the remote controller 50 does not recognize the target device whose control board has been replaced, the process proceeds to step S6.

[0031] In step S10, as shown in the pop-up B10, the remote controller 50 displays on the display unit 51 a notification screen D10 prompting the setting of part number information for the replaced control board, and then proceeds to step S6. Pop-up B10 illustrates the case where the control board 11a of the first outdoor unit 10a has been replaced. The operator W can confirm the notification screen D10 and operate the decision button 56 to switch to the part number information change screen D6 for the control board 11a after replacement shown in FIG. 6 described later, and change the part number information stored in the first memory 12a of the control board 11a.

[0032] In step S6, the remote controller 50 recognizes the presence or absence of the target device whose part number information (set part number information) stored in the first memory of the control board deviates from the setting conditions. Then, when the remote controller 50 recognizes the target device whose set part number information deviates from the setting conditions, the process proceeds to step S11, and when the remote controller 50 does not recognize the target device whose set part number information deviates from the setting conditions, the process proceeds to step S7.

[0033] In step S11, as shown in the callout B11, the remote controller 50 displays on the display unit 51 an alert screen D11 that prompts for a change to the set product number information that deviates from the set conditions, and proceeds with the process to step S7. Callout B11 illustrates a case where the set product number information stored in the first memory 22a of the control board 21a of the first indoor unit 20a deviates from the set conditions. The operator W can check the alert screen D11 and operate the decision button 56 to switch to the product number information change screen D6 described later, and change the product number information stored in the first memory 22a of the control board 21a to appropriate product number information.

[0034] Here, as the set conditions for the product number information, for example, it is set that it is a maximum of 16 half-width characters combined with uppercase alphabet letters (A to Z) starting with an uppercase alphabet letter, numbers (0 to 9), or special characters (-, +, half-width space, etc.). Alternatively, as the product number conditions, for a plurality of target devices remotely operated by the remote controller 50, it may be set that the product number information stored in the first memory of the control board provided in each target device has a predetermined continuity (for example, the consecutive alphabetical order shown in FIG. 1).

[0035] [4. Setting process for product number information] According to the flowchart shown in FIG. 5, while referring to FIG. 6, the procedure of the product number information setting process by operating the remote controller 50 will be described.

[0036] In step S50 of FIG. 5, when the remote controller 50 recognizes a selection operation of the product number information setting menu by the operator W, it proceeds with the process to step S51. In step S51, the remote controller 50 displays on the display unit 50 the product number information change screen D1 shown in FIG. 6. On the product number information change screen D1, the target devices connected to the remote controller 50 are listed. The operator W operates the up button 52 or the down button 53 to switch the target device to be selected, and operates the decision button 56 to confirm the selected target device. Also, the product number information change screen D1 is scrolled and displayed as D2 and D3.

[0037] When the target device to be selected is determined by operating the determination button 56, the remote controller 50 switches to the part number information change screen D4. The part number information change screen D4 in FIG. 6 illustrates a state in which the first outdoor unit 10a is selected. The part number information change screen D4 illustrates a case where the control board 11a of the first outdoor unit 10a is replaced and the dummy part number information "XYZ" stored in the first memory 12a of the control board 11a is displayed. When the return button 57 is operated while the part number information change screen D4 is being displayed on the display unit 51, the remote controller 50 returns the display on the display unit 51 to the part number information change screen D1.

[0038] When the determination button 56 is operated while the part number information change screen D4 is being displayed on the display unit 51 of the remote controller 50, the remote controller 50 switches the display on the display unit 51 to the part number information change screen D6. On the part number information change screen D6, the part number information ("XYZ") that is the part number information (currently set part number information) stored in the first memory 12a of the control board 11a after replacement of the first outdoor unit 10a is displayed. Also, on the part number information change screen D6, the part number information ("A") that is the part number information (set part number information) of the control board 11a (control board 11a before replacement) of the first outdoor unit 10a when the remote operation system 1 was installed and recorded in the model information table 60 shown in FIG. 4 is displayed.

[0039] Also, the remote controller 50 accepts changes to the content of the part number information in response to operations of the left button 54, right button 55, up button 52, and down button 53. Specifically, the remote controller 50 shifts the position (digit) of the part number information to be changed left or right in response to an operation of the left button 54 or right button 55, and scrolls and changes the display characters to be selected in response to an operation of the up button 52 or down button 53.

[0040] The remote controller 50 displays a change confirmation screen D7 that displays the part number information before the change (here, "XYZ") and the part number information after the change (here, the set part number information "A") in response to an operation of the determination button 56, and when the determination button 56 is operated in a state where "Yes" is selected (in a white-out display state), it recognizes the completion of the designation of the part number information after the change (here, the designation of "A").

[0041] Through the loop processing of step S52 and step S60 in FIG. 5, when the remote controller 50 recognizes the completion of specifying the product number information in step S52, it proceeds to step S53, and when it recognizes the end of selecting the product number information setting menu in step S60, it proceeds to step S54.

[0042] In step S53, the remote controller 50 transmits the product number information (designated product number information) specified on the product number information change screen D6 to the selected target device (here, the first outdoor unit 10a). The first outdoor unit 10a (more specifically, the control board 11a of the first outdoor unit 10a) proceeds to step S71 when it receives the designated product number information transmitted from the remote controller 50 in step S70. In step S71, the first outdoor unit 10a stores the designated product number information in the first memory 12a. As a result, the product number information stored in the first memory 12a is changed to the designated product number information specified on the product number information change screen D6.

[0043] [5. Effects, etc.] As described above, in the present embodiment, the operator W can change the product number information stored in the first memory provided in the control board of the target devices (the first outdoor unit 10a, the second outdoor unit 10b, the first indoor unit 20a, the second indoor unit 20b, the third outdoor unit 20c, the ventilation device 30) connected to the remote controller 50 by a simple operation of the remote controller 50. Thereby, maintenance such as replacement of the control board provided in the target device can be facilitated.

[0044] (Other Embodiments) As described above, the above embodiments have been described as examples of the technology disclosed in the present application. However, the technology in the present disclosure is not limited to this, and can also be applied to embodiments with changes, replacements, additions, omissions, etc. Therefore, other embodiments will be exemplified below.

[0045] In the above embodiment, examples of target devices remotely controlled by the remote controller of the present disclosure include the first outdoor unit 10a, the second outdoor unit 10b, the first indoor unit 20a, the second indoor unit 20b, the third indoor unit 20c, and the ventilation device 30. Target devices of the present disclosure are not limited to these, and may also be an air purifier, a water heater, or the like that are remotely controlled by the remote controller.

[0046] In the above embodiment, when the target device whose control board has been replaced is recognized by the processing of steps S5 and S10 in Fig. 3, a notification screen D10 is displayed to prompt the user to set the product number information of the replaced control board, and a product number information change screen D6 (see Fig. 6) for the replaced control board is displayed. In another embodiment, the processing of steps S5 and S10 may be omitted.

[0047] In the above embodiment, as shown in Fig. 6, when a target device (ventilation device 30) whose product number information cannot be changed is selected on the product number information change screen D4, a screen D5 notifying that the setting cannot be changed is displayed on the display unit 51 of the remote control 50. In another embodiment, a sound notifying that the setting cannot be changed may be output from a speaker provided in the remote control 50. Also, the notification by the display unit 51 or the speaker that the setting cannot be changed may be omitted.

[0048] In the above embodiment, when a target device whose registered product number information deviates from the set conditions is recognized by the processing of steps S6 and S11 in Fig. 3, a notification screen D11 prompting the user to change the product number information to appropriate product number information is displayed on the display unit 51. In another embodiment, the processing of steps S6 and S11 may be omitted.

[0049] The control board provided in the target device of the present disclosure may be any controller capable of controlling the operation of the target device of the present disclosure. When describing the subject matter of the invention, the entity controlling the operation of the target device of the present disclosure may be referred to as a control board, control unit, controller, or similar terms. The control board can be realized in various forms. For example, the control board may use a processor as its controlling entity. Using a processor as its controlling entity enables various processes to be performed by loading a program from a storage medium storing the program into the processor and executing the program. This allows the processing content to be changed by modifying the program stored in the storage medium, thereby increasing the flexibility of changing the control content. Examples of processors include a central processing unit (CPU) and a microprocessing unit (MPU). Examples of storage media include a hard disk, flash memory, and optical disk. Furthermore, a wired logic device, whose program cannot be rewritten, may be used as the controlling entity of the control board. Using wired logic as the controlling entity of the control board is effective in improving processing speed. Examples of wired logic include an application-specific integrated circuit (ASIC). The controller may also be realized by combining a processor and wired logic. By combining a processor and wired logic to realize the main control unit of the control board, it is possible to increase the flexibility of software design while improving processing speed. The main control unit of the control board and a circuit having a function different from the main control unit may be configured with a single semiconductor element. An example of a circuit having a different function is an A / D / D / A conversion circuit. The main control unit may be configured with a single semiconductor element or multiple semiconductor elements. When configured with multiple semiconductor elements, each control described in the claims may be realized with a different semiconductor element. Furthermore, the control board may be configured with a semiconductor element and a passive component such as a resistor or capacitor.

[0050] The communication circuit (communication interface) as a communicator provided in the target device and the remote control in this disclosure may be any circuit that enables communication between the target device and the remote control in this disclosure. When describing the subject matter of the invention, the term "communicator" may also be used to refer to a communication means, a communication unit, a transmission / reception means, a transmission / reception unit, or similar terms as a means for enabling communication between the elements constituting the target device and the remote control in this disclosure. The communicator can be realized in various ways. Examples of the communicator include a wireless connection with an external device via a base station or a direct wireless connection with an external device. Examples of wireless connections with an external device via a base station or the like include an IEEE 802.11-compatible wireless LAN that wirelessly communicates with a Wi-Fi (registered trademark) router, a third-generation mobile communication system (commonly known as 3G), a fourth-generation mobile communication system (commonly known as 4G), an IEEE 802.16-compatible WiMax (registered trademark), and a Low Power Wide Area (LPWA) network. The use of a communicator that directly connects the device of the present disclosure to an external device wirelessly is effective in improving the security of communications, and also allows the device of the present disclosure to communicate with external devices even in places where there is no relay device such as a Wi-Fi (registered trademark) router. Examples of communicators that directly connect the device of the present disclosure to an external device wirelessly include communication via Bluetooth (registered trademark), communication via NFC (Near Field Communication) via a loop antenna, and infrared communication.

[0051] It should be noted that the above-described embodiments are intended to illustrate the technology of the present disclosure, and various modifications, substitutions, additions, omissions, etc. may be made within the scope of the claims or their equivalents.

[0052] (Addendum) The above description of the embodiments discloses the following techniques.

[0053] (Technology 1) A remote control system comprising a target device equipped with a control board having a first memory unit, and a remote controller that communicates with the control board to remotely operate the target device, wherein the control board receives designated product number information transmitted from the remote controller in response to a predetermined operation on the remote controller, and stores the designated product number information in the first memory unit. With this configuration, it is possible to facilitate the maintenance of the control board used in the target device remotely operated by the remote controller.

[0054] (Technology 2) The remote controller has a second memory unit and a display unit, and acquires, through communication with the control board, the set product number information which is the product number information stored in the first memory unit, stores the set product number information in the second memory unit, displays the set product number information stored in the second memory unit, and displays on the display unit a product number information change screen that accepts selection of the set product number information by the predetermined operation. When the set product number information is selected on the product number information change screen, the remote control system according to Technology 1, which transmits the set product number information to the control board as the designated product number information. With this configuration, when the control board of the target device is replaced, the work of storing and succeeding the set product number information stored in the first memory unit of the control board before replacement in the first memory unit of the control board after replacement can be facilitated.

[0055] (Technology 3) The remote controller includes a plurality of the target devices. The remote controller acquires the set product number information stored in the first storage unit of the control boards respectively provided in the plurality of the target devices through communication with the plurality of control boards, stores the information in the second storage unit, and when recognizing through communication with the plurality of target devices that the control board of any one of the target devices has been replaced, displays on the display unit a product number information change screen for the control board after replacement, which shows the set product number information stored in the first storage unit of the control board before replacement. When the set product number information is selected on the product number information change screen for the control board after replacement, the remote control system according to Technology 2 transmits the set product number information as the specified product number information to the control board after replacement. According to this configuration, when a plurality of target devices are remotely controlled by a remote controller, it is possible to easily recognize the target device whose control board has been replaced and perform the operation of storing and inheriting the set product number information stored in the first storage unit of the control board before replacement in the first storage unit of the control board after replacement.

[0056] (Technology 4) The remote controller recognizes through communication with the control board whether the product number information stored in the first storage unit can be changed. When the change of the product number information stored in the first storage unit is impossible, the remote controller notifies the operator or the like through the notification unit provided in the remote controller that the change of the product number information is impossible.
