(Embodiment)
[overview]
First, an overview of an information processing system according to an embodiment will be described. Fig. 1 is a block diagram showing an overview of an information processing system according to an embodiment.

The facility 80 shown in FIG. 1 is, for example, a residence such as an apartment building or a detached house, and includes multiple private areas 81 and a common area 82. Each of the multiple private areas 81 is an area where a resident lives, and an intercom device 20, a control device 30, and equipment 40 are installed in each of the private areas 81. The common area 82 is an area other than the private areas 81 in the facility 80, and is an area shared by multiple residents. A lobby intercom 50 and the like are installed in the common area 82. The lobby intercom 50 is communicatively connected to the multiple intercom devices 20 via a local communication network.

FIG. 1 also illustrates a server device 60 installed outside the facility 80. The server device 60 is communicatively connected to a plurality of control devices 30 via a wide area communication network 70 such as the Internet.

When a resident is staying in the private area 81, the control device 30 stores the resident's first personal setting information (hereinafter also referred to as first information), such as operation log information of the device 40. When a resident moves out of the private area 81 due to expiration of a rental contract or the like, there is room for consideration of a method for deleting the first personal setting information of the resident who has already moved out (hereinafter also referred to as the mover).

When a resident moves out, the resident or a manager or the like generally turns off the power supply from the distribution board of the private area 81 to the control device 30. At this time, the power supply to the intercom device 20 is often maintained. Therefore, the information processing system 10 detects the turning off of the power supply to the control device 30 (turning off the main power) accompanying the resident's departure by the intercom device 20, which maintains the power supply even when the resident leaves, and deletes the first personal setting information when it is estimated that the resident has left.

[composition]
Next, the functional configuration of such an information processing system 10 will be described with reference to Fig. 2 in addition to Fig. 1. Fig. 2 is a block diagram showing the functional configuration of the information processing system 10. Note that, for convenience, only one exclusive section 81 is shown in Fig. 2.

As shown in Figures 1 and 2, the information processing system 10 includes an intercom device 20, a handset 27, an electric lock 28, a control device 30, a number of devices 40, a lobby intercom 50, and a server device 60.

First, the intercom device 20 will be described. The intercom device 20 is another example of an information terminal, and is fixedly installed, for example, in each of the multiple private areas 81. The intercom device 20 and the handset 27 form an intercom system. The intercom device 20 is the parent device in the intercom system. The intercom device 20 includes a display unit 21, a communication unit 22, a control unit 23, and a memory unit 24.

The display unit 21 is a display device having the function of displaying images and the function of accepting manual input from the resident. The display unit 21 is realized by a display panel such as a touch panel, a liquid crystal panel, or an organic EL panel. The touch panel is, for example, a capacitive touch panel, but may also be a resistive touch panel. Note that it is not essential for the display unit 21 to have the function of accepting manual input from the resident, and an input acceptance unit such as a hardware button may be provided separately from the display unit 21.

The communication unit 22 is a communication module (communication circuit) that allows the intercom device 20 to communicate with the handset 27, the electric lock 28, the control device 30, and the lobby intercom 50. The communication unit 22 communicates with, for example, the handset 27, the electric lock 28, the control device 30, and the lobby intercom 50 via a local communication network. The communication performed by the communication unit 22 is, for example, wireless communication, but may also be wired communication. The communication unit 22 may have both wireless communication and wired communication functions. There are no particular limitations on the communication standard for the communication performed by the communication unit 22. Note that the communication via the local communication network complies with, for example, ECHONET Lite (registered trademark).

The control unit 23 controls the display of the image of the visitor captured by the handset 27 on the display unit 21, and controls the electric lock 28. The control unit 23 is realized, for example, by a microcomputer, but may also be realized by a processor.

The memory unit 24 is a storage device that stores computer programs executed by the control unit 23. The memory unit 24 is realized, for example, by a semiconductor memory.

The handset 27 is a so-called door phone that is installed at the entrance of the private area 81. Although details are not shown in the figure, the handset 27 includes a call button that a visitor presses, an imaging unit that captures an image (e.g., a moving image) of a visitor who presses the call button, and the like.

The electric lock 28 is a device that controls the unlocking and locking of doors (or windows, etc.) owned by the facility 80. The electric lock 28 is provided, for example, on the front door of the private area 81. The electric lock 28 is unlocked and locked by an authentication medium, for example, a card key. The electric lock 28 may also be unlocked and locked based on a control signal transmitted from the intercom device 20.

Next, the control device 30 will be described. The control device 30 is, for example, a HEMS (Home Energy Management System) controller having an energy management function. For example, the control device 30 is fixedly installed in each of the multiple private units 81. The control device 30 manages the power consumption of the devices 40 installed in the private units 81. The control device 30 is an example of an information terminal. The control device 30 is a local controller installed in the private unit 81 as a device separate from the devices 40 (i.e., not built into the devices 40). In addition, the control device 30 acquires and displays the status of the devices 40, and controls the devices 40 installed in the private unit 81. The control device 30 is not limited to a HEMS controller, and may be another EMS controller, another home controller without an energy management function, or a gateway device. Specifically, the control device 30 includes a display unit 31, a communication unit 32, a control unit 33, and a storage unit 34.

The display unit 31 is a display device having a function of displaying images and a function of accepting manual input from a user. The display unit 31 is realized by a display panel such as a touch panel, a liquid crystal panel, or an organic EL panel. The touch panel is, for example, a capacitive touch panel, but may also be a resistive touch panel.

The communication unit 32 is a communication module (communication circuit) that allows the control device 30 to communicate with the intercom device 20, the device 40, and the server device 60. The communication unit 32 communicates with the intercom device 20 and the device 40, for example, via a local communication network, and with the server device 60, via a wide area communication network 70. The communication performed by the communication unit 32 is, for example, wireless communication, but may also be wired communication. The communication unit 32 may have both wireless communication and wired communication functions. The communication standard of the communication performed by the communication unit 32 is not particularly limited. Note that the communication via the local communication network complies with, for example, ECHONET Lite (registered trademark).

The control unit 33 controls the display of images on the display unit 31 and controls the device 40. The control unit 33 is realized, for example, by a microcomputer, but may also be realized by a processor.

The memory unit 34 is a storage device that stores the first personal setting information (specifically, operation log information of the device 40, etc.). The memory unit 34 also stores computer programs executed by the control unit 33, etc. In the memory unit 34, the first personal setting information is stored in a dedicated area so that it can be distinguished from other information. The memory unit 34 is realized, for example, by a semiconductor memory.

Next, the device 40 will be described. The device 40 is a device that is controlled by the control device 30. The device 40 includes, for example, a communication module (communication circuit) for communicating with the control device 30, and operates according to a control signal received from the control device 30. The device 40 includes, for example, an air conditioning device 41 and a lighting device 42.

The air conditioning equipment 41 is equipment that takes in air from the space within the private area 81 (within the facility 80), adjusts at least one of the temperature and humidity, and releases the air into the space. A heat exchanger or the like is used to adjust the temperature. The air conditioning equipment 41 is, for example, an air conditioner for general household use, but may also be an industrial air conditioner.

The lighting equipment 42 illuminates the exclusive area 81 (inside the facility 80). The lighting equipment 42 is, for example, a ceiling light, but the specific form of the lighting equipment 42 is not particularly limited. The lighting equipment 42 may be a downlight, a pendant light, a spotlight, a bracket light, or the like.

Although not shown, each of the air conditioning equipment 41 and the lighting equipment 42 has a memory unit, and this memory unit stores third personal setting information (e.g., set temperature information of the air conditioning equipment 41, and lighting setting information of the lighting equipment 42). In the memory unit, the third personal setting information is stored in a dedicated area so as to be distinguishable from other information. The memory unit is realized, for example, by a semiconductor memory.

Next, the lobby intercom 50 will be described. The lobby intercom 50 is a device that is installed at the entrance of the facility 80 (i.e., the common area 82) or the like. The lobby intercom 50 is used, for example, to release the so-called auto-lock. Although details are not shown, the lobby intercom 50 is equipped with a numeric keypad that allows a visitor to enter the number of a specific private area 81, a call button, and an imaging unit that captures an image (e.g., a video image) of a visitor who presses the call button.

Next, the server device 60 will be described. The server device 60 is, for example, a cloud server installed outside the facility 80. The server device 60 includes a storage unit 61 that stores second personal setting information of the resident of the facility 80 in association with the ID of the control device 30. FIG. 3 is a diagram showing an example of second personal setting information stored in the storage unit 61. In the storage unit 61, the second personal setting information is stored so as to be distinguished from other information, for example, by being associated with the ID of the control device 30 and stored in a dedicated area. The storage unit 61 is realized, for example, by a hard disk drive.

[Operation example 1]
Next, a description will be given of a first operation example of the information processing system 10. FIG.

The communication unit 22 of the intercom device 20 and the communication unit 32 of the control device 30 communicate periodically while activated (S11). When the resident (target person) leaves and the distribution board of the private area 81 is operated, the power supply to the control device 30 is turned off (S12). At this time, the power supply to the intercom device 20 is not turned off.

The control unit 23 of the intercom device 20 detects that communication between the communication unit 22 and the control device 30 has been cut off (S13). In other words, the control unit 23 indirectly detects that the power supply to the control device 30 has been turned off.

Thereafter, when the power supply to the control device 30 is turned on by the new resident or the like operating the distribution board of the exclusive area 81 (S14), the communication unit 22 of the intercom device 20 and the communication unit 32 of the control device 30 resume communication (S15). At this time, the control unit 23 detects that communication between the communication unit 22 and the control device 30 has resumed (S16), and determines whether the period from when communication was cut off to when communication was resumed is equal to or longer than a predetermined period (S17). In other words, the control unit 23 determines whether the length of the operation suspension period from when the power supply to the control device 30 was stopped to when it was resumed is equal to or longer than a predetermined period. The length of the predetermined period is, for example, 24 hours, but may be determined empirically or experimentally as appropriate.

If it is determined that the length of time from when communication is cut off to when communication is resumed is less than the predetermined time, the processing from step S18 onwards is not performed. If the control unit 23 determines that the length of time from when communication is cut off to when communication is resumed is equal to or greater than the predetermined time, it causes the communication unit 22 to transmit a first command to the control device 30 requesting the deletion of the first personal setting information (S18).

The first personal setting information is information generated by the use of the control device 30 while the departing person was residing in the private section 81 (in other words, staying in the facility 80). In other words, the first personal setting information is information related to the departing person. The first personal setting information includes, for example, setting information intentionally set by the departing person when he/she was residing in the private section 81 (for example, screen setting information of the display section 31, name setting information of the rooms in the private section 81, and application programs installed by the departing person). The first personal setting information also includes information automatically generated by the control device 30 when the departing person was residing in the private section 81, such as operation log information of the device 40 and history information of energy consumption in the private section 81. In the case where a mobile terminal such as a smartphone can be connected to the control device 30 for communication, the first personal setting information may include connection setting information of the mobile terminal. The first personal setting information may also include information for performing scene control (information indicating how to combine multiple devices), which will be described later.

When the communication unit 32 receives the first command, the control unit 33 of the control device 30 causes the display unit 31 to display a notification screen that prompts the user to delete the first personal setting information (S19). Figure 5 shows an example of the notification screen.

When a notification screen such as that shown in FIG. 5 is displayed and an operation to approve the deletion of the first personal setting information is received by the display unit 31 (S20), the control unit 33 deletes the first personal setting information from the storage unit 34 (S21). As described above, the first personal setting information is stored in a dedicated area in the storage unit 34 so that it can be distinguished from other information, and therefore the control unit 33 can selectively delete the first personal setting information. Note that steps S19 and S20 may be omitted. In other words, the first personal setting information may be deleted without an operation to approve the deletion of the first personal setting information.

In addition, upon receiving the first command, the control unit 33 causes the communication unit 32 to send a second command to the server device 60 (S22). That is, when the control unit 33 determines that the length of the operation suspension period is equal to or longer than a predetermined period, the control unit 33 causes the communication unit 32 to send a command requesting the server device 60 to delete the second information related to the departing person that is held by the server device 60. The second command is a command requesting the server device 60 to delete the second personal setting information related to the departing person. Note that if communication with the server device 60 has not been established at the time the first command is received, a process of establishing communication is performed first.

The second personal setting information is information generated by the use of the control device 30 while the departing person was residing in the private area 81 (in other words, staying at the facility 80). In other words, the second personal setting information is information related to the departing person. As shown in FIG. 3 above, the second personal setting information includes, for example, user registration information registered by the departing person to receive services using the server device 60, and backup information of the first personal setting information. Services using the server device 60 include, for example, a service for remotely controlling the control device 30 and the equipment 40 from outside the facility 80 via a mobile terminal such as a smartphone, and a notification service regarding power consumption to the mobile terminal.

When the server device 60 receives the second command, it deletes the second personal setting information from the memory unit 61 provided in the server device 60 based on the received second command (S23). As described above, in the memory unit 61 provided in the server device 60, the second personal setting information is stored in a dedicated area in association with the ID of the control device 30 so that it can be distinguished from other information, and therefore the server device 60 can selectively delete the second personal setting information. Note that the second command includes the ID of the control device 30 that sent the second command, and the server device 60 can selectively delete the second personal setting information associated with the ID included in the second command.

Furthermore, upon receiving the first command, the control unit 33 causes the communication unit 32 to transmit a third command to each of the multiple devices 40 (S24). That is, when the control unit 33 determines that the length of the operation suspension period is equal to or longer than a predetermined period, the control unit 33 causes the communication unit 32 to transmit a third command requesting the deletion of third information related to the departing person held by the device 40. The third command is a command requesting the device 40 to delete the third personal setting information of the departing person. Note that, if communication with the device 40 has not been established at the time the first command is received, a process of establishing communication is performed first.

The third personal setting information is information generated by the use of the equipment 40 while the departing person was residing in the private unit 81 (in other words, staying in the facility 80). In other words, the third personal setting information is information related to the departing person. The third personal setting information includes, for example, setting information that was intentionally set by the departing person himself/herself while residing in the private unit 81 (for example, the set temperature information of the air conditioning equipment 41 and the lighting setting information of the lighting equipment 42).

When the device 40 receives the third command, it deletes the third personal setting information from the storage unit of the device 40 based on the received third command (S25). As described above, the third personal setting information is stored in a dedicated area in the storage unit of the device 40 so as to be distinguishable from other information, and therefore the device 40 can selectively delete the third personal setting information.

As described above, the control unit 23 of the intercom device 20 determines whether the length of the operation suspension period from when the power supply to the control device 30 is stopped until it is resumed is equal to or longer than a predetermined period, based on the communication state between the communication unit 22 and the control device 30. When the control unit 23 determines that the length of the operation suspension period is equal to or longer than the predetermined period, it transmits a first command to the control device 30 as control related to the deletion of the first personal information. By transmitting the first command, the control unit 23 causes the display unit 31 of the control device 30 to display a notification screen prompting the user to delete the first personal setting information, deletes the first personal setting information, and further causes the communication unit 32 of the control device 30 to transmit the second command and the third command.

As a result, a new resident or an administrator of the facility 80 can easily delete the first personal setting information, the second personal setting information, and the third personal setting information by turning on the main power of the control device 30. In other words, the information processing system 10 can assist in deleting information about a departing resident.

If the control device 30 does not have a display unit 31, the notification screen in FIG. 3 may be displayed on the display unit 21 of the intercom device 20 instead of the display unit 31.

In addition, in the operation example 1, the relationship between the intercom device 20 and the control device 30 may be reversed. In other words, the control device 30 may determine whether the length of the operation suspension period from when the power supply to the intercom device 20 is stopped until it is resumed is equal to or longer than a predetermined period, and may instruct the intercom device 20 and the lobby intercom 50 connected to the intercom device 20 to delete the personal setting information.

[Operation example 2]
Next, a description will be given of an operation example 2 of the information processing system 10. FIG.

When the resident leaves and the power supply to the control device 30 is turned off by operating the distribution board in the private area 81, the control unit 33 of the control device 30 detects that the power supply to the control device 30 has been turned off using a backup power source (e.g., a capacitor) (S31), and stores in the memory unit 34 off-time information indicating the time when the power supply was turned off (S32).

When the power supply to the control device 30 is then turned on by a new resident or the like operating the distribution board in the exclusive area 81, the control unit 33 detects that the power supply has been turned on (S33) and, based on the off time information stored in the memory unit 34, determines whether the length of the outage period from when the power supply to the control device 30 was stopped until it was restarted is equal to or longer than a predetermined period (S34).

If it is determined that the length of the operation suspension period is less than the predetermined period, the processing from step S35 onwards is not performed. If it is determined that the length of the operation suspension period is equal to or greater than the predetermined period, the processing from steps S35 to S41 is performed. The processing from steps S35 to S41 is the same as the processing from steps S19 to S25 in operation example 1.

As described above, in operation example 2, the control unit 33 of the control device 30 determines whether the length of the operation suspension period from when the power supply to the control device 30 is stopped to when it is restarted is equal to or longer than a predetermined period. When the control unit 33 determines that the length of the operation suspension period from when the power supply to the control device 30 is stopped to when it is restarted is equal to or longer than a predetermined period, the control unit 33 performs control related to the deletion of the first personal setting information. As control related to the deletion of the first personal setting information, the control unit 33 causes the display unit 31 to display a notification screen prompting the deletion of the first personal setting information, and deletes the first personal setting information. In addition to the control related to the deletion of the first personal setting information, the control unit 33 also causes the communication unit 32 to transmit a second command and a third command.

As a result, a new resident or an administrator of the facility 80 can easily delete the first personal setting information, the second personal setting information, and the third personal setting information by turning on the main power of the control device 30. In other words, the information processing system 10 can assist in deleting information about a departing resident.

In the second operation example, the control device 30 deletes the first personal setting information stored in the control device 30, but the intercom device 20 may perform a similar operation. In other words, the control unit 23 of the intercom device 20 may determine whether the length of the operation suspension period from when the power supply to the intercom device 20 is stopped until it is resumed is equal to or longer than a predetermined period, and delete the first personal setting information stored in the memory unit 24 of the intercom device 20.

The first personal setting information stored in the memory unit 24 includes, for example, setting information that was intentionally set by the departing person when he or she was residing in the private unit 81 (e.g., screen setting information for the display unit 21 and volume setting information for the ringtone). The first personal setting information stored in the memory unit 24 also includes information that was automatically generated by the intercom device 20 when the departing person was residing in the private unit 81 (e.g., image information of the visitor).

[Modification]
The first personal setting information may include information for executing scene control. In other words, scene control is collective control of a plurality of devices installed in the facility 80, and is generally executed by the control device 30. Fig. 7 is a diagram showing an example of information for executing scene control.

In the information for executing scene control shown in FIG. 7 (hereinafter also referred to as control information for scene control), the control contents of multiple devices are linked to each of life scenes (scene names) such as waking up, going out, and going to bed. The control information for scene control is stored in the memory unit 34 as one piece of first personal setting information.

For example, when a user operates the display unit 31 of the control device 30 to instruct execution of the "wake up" scene control, the control unit 33 refers to the control information of FIG. 7 stored in the memory unit 34 and turns on the air conditioning equipment 41 and the lighting equipment 42 with the preregistered settings (brightness, set temperature, etc.). Note that the resident can set which equipment will perform what operation when execution of each scene control is instructed.

Incidentally, the "sleep" scene control includes the electric lock 28 as a control target, but as shown in Figures 1 and 2, the control device 30 and the electric lock 28 are not connected for communication. On the other hand, the intercom device 20 is connected for communication with the electric lock 28. In such a case, the control information for scene control is stored not only in the memory unit 34 of the control device 30, but also in the memory unit 24 of the intercom device 20. This allows the control device 30 to request the intercom device 20 to control the electric lock 28 when an instruction to execute scene control is received.

In this way, the first personal setting information may include control information for scene control. Such control information for scene control is, for example, information for collectively controlling the electric lock 28 (an example of a first device) that is communicatively connected to the communication unit 22 and not communicatively connected to the control device 30, and the air conditioning equipment 41 and the lighting equipment 42 (an example of a second device) that are not communicatively connected to the communication unit 22 and are communicatively connected to the control device 30.

[Effects, etc.]
As described above, the information processing system 10 includes a memory unit (memory unit 24 or memory unit 34) that stores first personal setting information generated by a subject's use of an information terminal (intercom device 20 or control device 30), and a control unit (control unit 23 or control unit 33) that executes control related to the deletion of the first personal setting information when it is determined that the length of the operation suspension period from when the power supply to the information terminal is stopped until it is restarted is equal to or longer than a predetermined period. The first personal setting information is an example of first information.

Such an information processing system 10 can assist in deleting information about a target person after that person has left the facility.

For example, the information processing system 10 further includes a display unit (display unit 21 or display unit 31), and the control unit controls the display unit to display a notification screen prompting the user to delete the first personal setting information as a control related to the deletion of the first personal setting information.

Such an information processing system 10 can prompt the deletion of the first personal setting information.

Also, for example, the control unit deletes the first personal setting information as a control related to the deletion of the first personal setting information.

Such an information processing system 10 can delete the first personal setting information.

For example, the information terminal (control device 30) also includes a communication unit 32 that is communicatively connected to the server device 60 via the wide area communication network 70. When the control unit (control unit 23 or control unit 33) determines that the length of the operation suspension period is equal to or longer than a predetermined period, it causes the communication unit 32 to transmit a command requesting the deletion of second personal setting information related to the subject held by the server device 60. The second personal setting information is an example of second information.

Such an information processing system 10 can delete the second personal setting information.

For example, the information terminal (control device 30) includes a communication unit 32 that is communicatively connected to the device via a local communication network, and when the control unit (control unit 23 or control unit 33) determines that the length of the operation suspension period is equal to or longer than a predetermined period, it causes the communication unit 32 to transmit a command requesting the deletion of third personal setting information related to the subject held by the device 40. The third personal setting information is an example of third information.

Such an information processing system 10 can delete the third personal setting information.

For example, the memory unit 34 is provided by an information terminal (control device 30), and the control unit 23 is provided by an information terminal other than the information terminal (intercom device 20).

Such an information processing system 10 can indirectly detect when power supply to an information terminal is turned off and restarted using another information terminal.

For example, the control unit 23 also determines whether the length of the operation suspension period is equal to or longer than a predetermined period based on the communication state of other information terminals (intercom device 20) and the information terminal (control device 30).

Such an information processing system 10 can indirectly detect when power supply to an information terminal is turned off and resumed based on the communication state.

For example, the information terminal is a control device 30 (EMS controller), and the other information terminal is an intercom device 20.
