JP 2006-279829 A

  The resident of the house where the equipment is installed may change. In this case, it is necessary to make the remote operation of the equipment device impossible by a resident who has moved out of the house (hereinafter referred to as “pre-resident”). In Patent Literature 1, the center device invalidates the issued authentication information after the previous resident has left. Thereby, the remote operation of the facility apparatus by the previous resident becomes impossible. However, when a new resident (hereinafter referred to as a “new resident”) moves in, the issued authentication information may not yet be invalidated in the center device. In this case, the facility apparatus is remotely operated by a previous resident.

  The present specification provides a technique that can surely invalidate a remote operation by a resident who has moved out after the resident of the house where the equipment is installed is replaced.

  The facility apparatus disclosed in the present specification includes a display unit, a function execution unit capable of executing a specific function, and a control unit including a memory, and the control unit stores authentication information in the memory. When the authentication information matching the authentication information stored in the memory and the function execution instruction are received from the terminal device, the function execution unit is caused to execute the specific function. The controller is configured to detect that the power supply has recovered from a power failure, and when the first authentication information is stored in the memory and detects that the power supply has recovered from a power failure, A selection screen for allowing the user to select whether or not to change the first authentication information is displayed on the display unit, and the user selects to change the first authentication information on the selection screen. In case Erases the first authentication information stored in the memory may store different second said authentication information in said memory and said first authentication information.

  When the resident of the house where the equipment is installed is changed, the supply of power to the equipment is stopped until the new resident enters after the previous resident leaves. That is, it becomes a power failure state. According to said structure, a control part displays a selection screen on a display part, when detecting having returned from the power failure. Then, when the new resident selects to change the first authentication information, the control unit deletes the first authentication information and stores the second authentication information in the memory. Therefore, even if the control unit receives the first authentication information and the function execution instruction from the previous tenant's terminal device after storing the second authentication information in the memory, the control unit Do not execute the function. That is, after a new resident moves in, the remote operation of the facility device by the previous resident can be surely invalidated.

  The facility apparatus may include an operation setting unit for setting whether or not to display the selection screen on the display unit when detecting that the control unit has recovered from the power failure.

  Even when the resident is not replaced, the power supply to the equipment may be stopped. For example, a planned power outage. In such a situation, whenever a selection screen is displayed on the display unit every time recovery from a power failure, it is troublesome for the resident. According to said structure, the resident | tenant can select not displaying a selection screen on a display part, when a control part detects a power failure. Therefore, it is possible to prevent the selection screen from being displayed unnecessarily in a situation where the resident has not been replaced.

Further, the user can set the current date and time Tc by operating the operation unit 44. Hereinafter, the display unit 42 and the operation unit 44 may be collectively referred to as “remote control operation unit”.

  The remote controller control unit 50 includes a CPU 52 and a memory 54. The memory 54 stores the current date and time Tc. Further, the memory 54 stores identification information “XXX” of the hot water supply device 10 that can communicate with the remote controller 40. The identification information “XXX” is information assigned in advance to the water heater 10 and is unique to the water heater 10. The identification information is, for example, the serial number of the hot water supply device 10. The CPU 52 generates authentication information according to the program stored in the memory 54 and stores the authentication information in the memory 54. The authentication information is information used when the hot water supply device 10 is remotely operated using the hot water supply application 116 described later.

(Hot water operation)
Next, the hot water filling operation executed by the hot water supply apparatus 10 will be described. The hot water filling operation is an operation for supplying hot water to a bathtub that is a hot water supply location. CPU22 heats the water in a tank by driving a heat pump, and supplies warm water to a bathtub. When the temperature of the water supplied from the tank to the bathtub is lower than the hot water supply set temperature, the CPU 22 supplies the water heated to the hot water supply set temperature to the hot water supply location by driving the burner. When a predetermined amount of hot water is supplied to the bathtub, the hot water filling operation ends.

(Configuration of mobile terminals 100 and 200)
The mobile terminal 100 is a portable terminal device such as a mobile phone or a smartphone. The mobile terminal 100 can access the Internet 8. The mobile terminal 100 includes a display unit 102 and a terminal control unit 110. The display unit 102 is a display for displaying various information, and also functions as a so-called touch panel (that is, an operation unit). The terminal control unit 110 includes a CPU 112 and a memory 114. The CPU 112 controls the operation of the mobile terminal 100 according to a program stored in the memory 114. The memory 114 stores a hot water supply application 116. The hot water supply application 116 is installed in the portable terminal 100 from a server (not shown) on the Internet 8, for example. The hot water supply application 116 is an application provided by the manufacturer of the hot water supply apparatus 10. The hot water supply application 116 is an application for transmitting various instructions to the hot water supply apparatus 10 without the user operating the remote control operation unit of the remote controller 40. That is, the hot water supply application 116 is an application for remotely operating the hot water supply apparatus 10. For example, the user of the portable terminal 100 can use the hot water supply application 116 to transmit an instruction for causing the hot water supply apparatus 10 to execute a hot water filling operation (hereinafter referred to as “hot water filling instruction”). The mobile terminal 200 has the same configuration as the mobile terminal 100. Hereinafter, a user who uses the mobile terminal 100 is referred to as a “first user”, and a user who uses the mobile terminal 200 is referred to as a “second user”.

(Configuration of management server 300)
The management server 300 is a server provided by the manufacturer of the hot water supply system 4. The management server 300 includes a server control unit 310. The server control unit 310 includes a CPU 312 and a memory 314. A management table 316 is stored in the memory 314. In the management table 316, identification information and authentication information are associated with each other.

(First remote operation setting (Case A); FIG. 2)
Next, referring to FIG. 2, when the first user uses the mobile terminal 100 to perform settings for remotely operating the hot water supply apparatus 10 (hereinafter referred to as “remote operation settings”). The process will be described. In case A, it is assumed that there is no record of remote control settings executed in the past. Therefore, in the initial state of FIG. 2, the management table 316 does not store the identification information “XXX” of the hot water supply device 10 and the authentication information corresponding to the identification information (the state before setting in FIG. 2). In the following, considering the ease of understanding, when describing the processing executed by the CPUs 22, 52, 112, 312 without describing the CPU as a main body, the apparatus (the hot water supply device 10, the remote controller 40, the portable device) is described. The terminal 100 and the management server 300) are mainly described.

  First, at T <b> 10, the first user performs a wireless connection operation for establishing a wireless connection between the remote controller 40 and the wireless LAN router 60. Specifically, the first user establishes a wireless connection between the remote controller 40 and the wireless LAN router 60 using WPS (abbreviation for Wi-Fi Protected Setup). WPS is a technology that allows a wireless connection to be easily established between a pair of devices even if wireless setting information (eg, SSID, password, etc.) for establishing a wireless connection is not input by a user. When the wireless connection with the wireless LAN router 60 is established, the remote controller 40 can access the Internet 8 via the wireless LAN router 60.

  When the wireless connection with the wireless LAN router 60 is established, the remote controller 40 generates authentication information “A1” at T12 and displays the authentication information “A1” on the display unit 42 at T14. Thereby, the first user can confirm the authentication information “A1”. For example, the remote controller 40 may generate authentication information “A1” by randomly selecting a character string, or may generate authentication information using the identification information “XXX” of the hot water supply system 4 or the like. . Then, at T16, the remote controller 40 transmits the identification information “XXX” of the hot water supply device 10 to the portable terminal 100 via the wireless LAN router 60, and stores the authentication information “A1” in the memory 54 at T18.

  When the mobile terminal 100 receives the identification information “XXX” at T16, the mobile terminal 100 displays an authentication information input screen on the display unit 102 at T20. At T <b> 22, the first user operates the display unit 102 to input the authentication information “A1” displayed on the display unit 42 of the remote controller 40 on the authentication information input screen. In this case, at T24, the mobile terminal 100 transmits the identification information “XXX” received at T16 and the authentication information “A1” input at T22 to the management server 300. In T26, the mobile terminal 100 stores the identification information “XXX” and the authentication information “A1” in the memory 114 in association with each other.

  When the management server 300 receives the identification information “XXX” and the authentication information “A1” in T24, the management server 300 associates the identification information “XXX” and the authentication information “A1” in T30 and registers them in the management table 316 (FIG. 2). State after setting). As a result, the identification information “XXX” and the authentication information “A1” are stored in the memory 54 of the remote controller 40, the memory 114 of the portable terminal 100, and the memory 314 of the management server 300. Thus, the remote operation setting is completed.

(Remote operation (Case B); Fig. 3)
Next, with reference to FIG. 3, a process in which the first user performs a remote operation on the hot water supply device 10 using the hot water supply application 116 will be described. The initial state of FIG. 3 is a state after FIG. 2, that is, a state where the remote operation setting is completed. In this case, it is assumed that the first user is out.

  In T100, the first user operates the portable terminal 100 to start the hot water supply application 116 and executes a hot water filling execution operation. The hot water filling execution operation is an operation for causing the hot water supply device 10 to execute the hot water filling operation.

  In T102, the portable terminal 100 transmits a hot water filling instruction, identification information “XXX”, and authentication information “A1” to the management server 300. The hot water filling instruction is an instruction for causing the hot water supply apparatus 10 to execute the hot water filling operation.

  The management server 300 determines that the identification information “XXX” and the authentication information “A1” received in T102 match the identification information “XXX” and the authentication information “A1” stored in the management table 316, and in T110, Transmission of the hot water filling instruction to the hot water supply system 4 (specifically, the remote controller 40) is permitted. Then, at T112, the management server 300 transmits the hot water filling instruction, the identification information “XXX”, and the authentication information “A1” to the remote controller 40 via the wireless LAN router 60. The management server 300 permits transmission of the hot water filling instruction to the remote control 40 when the received identification information and authentication information do not match any combination of the identification information and authentication information stored in the management table 316. do not do.

  The remote controller 40 determines that the identification information “XXX” and the authentication information “A1” received at T112 match the identification information “XXX” and the authentication information “A1” stored in the memory 54. At T114, A hot water filling instruction is transmitted to hot water supply apparatus 10.

  In response to receiving the hot water filling instruction at T114, the hot water supply apparatus 10 executes the hot water filling operation at T120. Thereby, the 1st user can make hot water supply apparatus 10 perform hot water filling operation, even if the 1st user has gone out.

(First power outage sequence (Case C); Fig. 3)
Next, processing executed after the first power failure occurs will be described with reference to FIG. The first power failure is, for example, a planned power failure, and the supply of power to the hot water supply system 4 is stopped despite the ON state of the breaker (not shown) to which the hot water supply system 4 is electrically connected. It is in a state. The initial state of case C is the same as the initial state of case B except that the first power failure has occurred.

  At the power failure recovery time Tr, the first power failure is restored. In this case, the supply of electric power to the hot water supply system 4 is resumed, and the hot water supply apparatus 10 and the remote controller 40 are turned on. When the time during which a power failure has occurred is longer than a predetermined time (for example, 5 minutes), the current date and time Tc set in the remote controller 40 is an initial setting date and time (for example, “January 1, 2000, 00:00:00 ”) In this case, it is assumed that the power outage has continued for about 2 hours. For this reason, after the first power failure is restored, the current date Tc has returned to the initial setting date.

  At T200, the remote controller 40 detects that the power has returned from the power failure. Specifically, the remote controller 40 determines that it has recovered from a power failure because the current date and time Tc set in the remote controller 40 is the initial setting date and time.

  When it is determined that the remote controller 40 has recovered from the power failure and the authentication information “A1” is stored in the memory 54, the confirmation screen S1 (see FIG. 5A) is displayed on the display unit 42 in T210. To do. On the confirmation screen S1, for example, a message “If the resident changes due to a new move, the authentication information necessary to use the hot water supply application is changed.” Is displayed. When the first user confirms the message displayed on the confirmation screen S1, the first user operates the confirmation button 44b in T212.

  In response to the confirmation button 44b being operated by the first user, the remote controller 40 displays the selection screen S2 (see FIG. 5B) on the display unit 42 at T220. Buttons (“Yes” and “No”) for selecting whether or not the resident has changed are displayed on the selection screen S2. In this case, the resident has not changed before and after the power failure. For this reason, at T222, the first user operates the remote control operation unit to select “No”.

  When “No” is selected by the first user, the remote controller 40 displays a normal screen (not shown) on the display unit 42 at T230. The normal screen is a screen on which, for example, an instruction for transmitting a hot water filling instruction to the hot water supply apparatus 10 can be input. Note that the first user does not display the confirmation screen S1 and the selection screen S2 on the display unit 42 even when it is detected that the remote control 40 has recovered from the power failure by operating the remote control operation unit. As can be set in advance. In this case, the remote controller 40 displays the normal screen on the display unit 42 without displaying the confirmation screen S <b> 1 and the selection screen S <b> 2 on the display unit 42 when detecting that the power has returned from the power failure.

(Second remote operation setting sequence (Case D); FIG. 4)
Next, with reference to FIG. 4, processing when the second user executes remote operation setting using the mobile terminal 200 will be described. Case D assumes a situation in which a second user moves in after the first user leaves. Therefore, in the initial state of FIG. 4, the management table 316 stores the identification information “XXX” of the hot water supply device 10 and the authentication information “A1” corresponding to the identification information (before setting in FIG. 4). State). In addition, the authentication information “A1” is stored in the memory 54 of the remote controller 40. In the initial state of FIG. 4, the breaker to which the hot water supply system 4 is electrically connected is set to the OFF state, and the supply of electric power to the hot water supply system 4 is stopped. That is, the hot water supply system 4 is in a power failure state. Also, a wireless LAN router 60 different from the wireless LAN router installed by the first user is installed by the second user.

  At T300, the second user changes the breaker from the OFF state to the ON state. Thereby, electric power is supplied to the hot water supply system 4, and the hot water supply apparatus 10 and the remote controller 40 are turned on. In a situation where the resident changes from the first user to the second user, the time during which the supply of power to the hot water supply system 4 is stopped is longer than the predetermined time. Therefore, the current date and time Tc set in the remote controller 40 has returned to the initial set date and time.

  T302 is the same as T200 in FIG. T310 to T320 are the same as T210 to T220 in FIG. When the selection screen S2 is displayed, in T322, the second user operates the remote control operation unit to select “Yes”.

  When “Yes” is selected by the second user, the remote controller 40 changes the authentication information stored in the memory 54 at T324. Specifically, the remote controller 40 deletes the authentication information “A1” from the memory 54 and stores the new authentication information “A2” in the memory 54. At T330, the remote controller 40 displays the change completion screen S3 (see FIG. 5C) on the display unit 42. On the change completion screen S3, a message indicating that the change of the authentication information has been completed and a message prompting establishment of a wireless connection with the wireless LAN router 60 are displayed. When the confirmation button 44b is operated by the second user at T332, the remote controller 40 displays the normal screen on the display unit 42 at T334. Thereby, the remote controller 40 receives the identification information “XXX”, the authentication information “A1”, and the hot water filling instruction from the portable terminal 100 owned by the first user via the management server 300 and the wireless LAN router 60. Even so, the hot water filling instruction is not transmitted to the hot water supply apparatus 10. That is, at this time, the remote operation of the hot water supply device 10 by the first user is invalidated. It should be noted that the remote controller 40 performs the operation even when a normal operation such as an operation for transmitting a hot water filling instruction to the hot water supply device 10 is performed by the user in a state where the screens S1 to S3 are displayed on the display unit 42. Not accepted. That is, when the screens S1 to S3 are displayed on the display unit 42, the operations on the screens S1 to S3 are given priority.

  T340, T344, T346, and T350 to T360 are the same as T10, T14, T16, and T20 to T30 in FIG. 2 except that the authentication information “A2” is used instead of the authentication information “A1”. Thus, the remote operation setting is completed. Therefore, the second user can remotely operate the hot water supply apparatus 10 using the portable terminal 200.

  As described above, the resident who is in the house where the hot water supply system 4 is installed may be changed from the first user to the second user. When there is a track record of executing the remote operation setting by the first user, it is necessary to invalidate the remote operation of the hot water supply apparatus 10 using the portable terminal 100 owned by the first user. According to the above configuration, the remote controller 40 displays the selection screen S2 (see FIG. 5B) on the display unit 42 when detecting that the power has recovered from the power failure (T320 in FIG. 4). When the second user who is a new resident selects to change the authentication information “A1” (“Yes” in FIG. 5B) (T322 in FIG. 4), the remote controller 40 displays the authentication information. “A1” is deleted, and authentication information “A2” is stored in the memory 54 (T324 in FIG. 4). Therefore, the remote controller 40 may receive the authentication information “A1” and the hot water filling instruction from the portable terminal 100 owned by the first user after storing the authentication information “A2” in the memory 54. The hot water filling instruction is not transmitted to the hot water supply apparatus 10. That is, the hot water supply device 10 does not execute the hot water filling operation. Therefore, after the second user moves in, the remote operation of the hot water supply device 10 by the first user can be surely invalidated.

  In addition, the remote controller 40 includes a remote controller operation unit for setting whether or not to display the selection screen S2 on the display unit 42 when detecting that the power supply has recovered from the power failure. For example, even when a resident does not change like the first power failure, the power supply to the hot water supply system 4 may be stopped. In such a situation, if the selection screen S2 is displayed on the display unit 42, it is troublesome for the resident. According to the above configuration, it is possible to select not to display the selection screen S2 on the display unit 42 when the remote controller 40 detects a power failure in a state where the resident has not been replaced. That is, the selection screen S2 can be prevented from being displayed unnecessarily.
