[0021] (2) Details Hereinafter, the display system 1 according to the embodiment and the intercom system 2 including the display system 1 will be described in detail with reference to FIGS.

[0022] (2.1) Configuration 1, the intercom system 2 includes a display system 1, a control system 3, a first device 4, a second device 5, a detection system 6, a front door slave unit 7, a shared control system 8, and a lobby intercom 9. In the present embodiment, the display terminal serving as the display system 1 is, for example, an intercom master unit 10 (see FIG. 2).

[0023] The intercom system 2 is installed in a facility F1, which is, for example, an apartment building.

[0024] The facility F1 includes multiple dwelling units F2. The facility F1 also includes, for example, a common facility F3 shared by the residents of the multiple dwelling units F2. The common facility F3 may include, for example, a common entrance hall for the facility F1 or a management office. Note that, for the sake of explanation, only one dwelling unit F2 out of the multiple dwelling units F2 is shown in FIG. 1.

[0025] The shared facility F3 is provided with a shared control system 8, a lobby intercom 9, an elevator system 41 which is the first device 4, and the like.

[0026] Each of the multiple dwelling units F2 is equipped with an intercom master unit 10, a front door slave unit 7, an electric lock system 42 (first device 4), a control system 3, and a second device 5 controlled by the control system 3. The electric lock system 42 (first device 4) controls the locking / unlocking of the front door of the dwelling unit F2. The multiple second devices 5 installed in the dwelling unit F2 include at least one of, for example, lighting devices, air conditioning control devices, cooking appliances, hot water supply equipment, heating equipment, a power generation system, and a power storage system. Each of the multiple dwelling units F2 is also equipped with a detection system 6, such as a gas detector.

[0027] The configuration of each part of the intercom system 2 will be described in more detail below.

[0028] (2.1.1) Intercom base unit 1, intercom master unit 10, which is display system 1, includes first communication unit 11, second communication unit 12, and display unit 16. Intercom master unit 10 also includes third communication unit 13, fourth communication unit 14, fifth communication unit 15, call unit 17, control unit 18, operation unit 19, and memory unit 20.

[0029] The first communication unit 11 communicates with two first devices 4 (an elevator system 41 and an electric lock system 42) installed in the facility F1. The first communication unit 11 communicates with the elevator system 41 via the shared control system 8, which will be described in detail later.

[0030] The second communication unit 12 communicates with a control system 3 (described later) that controls a plurality of second devices 5 installed in the dwelling unit F2. In this embodiment, the plurality of second devices 5 includes at least one of a lighting device, an air conditioning control device, a cooking appliance, a hot water supply system, a heating system, a power generation system, and a power storage system installed in the dwelling unit F2. Note that, for the sake of explanation, FIG. 1 illustrates one second device 5 out of the plurality of second devices.

[0031] The third communication unit 13 is connected to a detection system 6, which is, for example, a gas detector. The third communication unit 13 receives the detection result of the detection system 6 from the detection system 6, for example, by wireless communication. Note that communication between the third communication unit 13 and the detection system 6 may be performed by a wired method.

[0032] Detection system 6 includes a detection unit that detects the condition of dwelling unit F2, an alarm unit that notifies the detection of an abnormality if an abnormality in the condition of dwelling unit F2 is detected, and a communication unit. The alarm unit of detection system 6 notifies the detection of the abnormality by issuing an alarm, for example, an alarm sound. If an abnormality is detected, the communication unit of detection system 6 notifies intercom master unit 10 by wireless communication via third communication unit 13 of information indicating the detection of the abnormality as a detection result.

[0033] When intercom master unit 10 receives information indicating that an abnormality has been detected from detection system 6, it displays, on display unit 16 (described later), information indicating that an alarm has been issued, for example.

[0034] The fourth communication unit 14 is connected to the lobby interphone 9 via the shared control system 8. For example, the fourth communication unit 14 receives an image transmitted from the lobby interphone 9 via the shared control system 8. Furthermore, the fourth communication unit 14 is configured to be able to communicate bidirectionally with the lobby interphone 9 via the shared control system 8 so that sound signals and control signals can be transmitted bidirectionally between the fourth communication unit 14 and the lobby interphone 9.

[0035] The lobby intercom 9 is installed, for example, at a common entrance included in the common facility F3. The lobby intercom 9 is equipped with an imaging device. When a visitor performs a call operation, the lobby intercom 9 starts capturing an image of the visitor using the imaging device. The lobby intercom 9 transmits data of the captured image to the intercom master unit 10 of the called dwelling unit F2 via the shared control system 8. Furthermore, the lobby intercom 9 transmits a control signal (call signal) to call, for example, user U1, who is a resident of dwelling unit F2, to the intercom master unit 10 via the shared control system 8. When a call can be established between the lobby intercom 9 and the intercom master unit 10 by performing a call start operation on the intercom master unit 10, the lobby intercom 9 transmits sound data including the visitor's voice to the intercom master unit 10 via the shared control system 8. When the lobby intercom 9 receives sound data from the operator of the intercom master unit 10, it outputs sound (including the operator's voice) based on the received data. When the intercom master unit 10 receives image data from the lobby intercom 9 via the shared control system 8, it displays the image captured by the lobby intercom 9 based on the received image data. While the intercom master unit 10 is receiving a control signal (call signal) from the lobby intercom 9 (i.e., when a visitor is calling via the lobby intercom 9), user U1 can talk to the lobby intercom 9 or unlock the lobby door via the shared control system 8.

[0036] The fifth communication unit 15 is connected to the front door slave unit 7. The fifth communication unit 15 and the front door slave unit 7 are configured to be able to communicate with each other.

[0037] The front door slave unit 7 is installed, for example, at the outer entrance of dwelling unit F2. The front door slave unit 7 is equipped with an imaging device. When a visitor performs a call operation, the front door slave unit 7 starts capturing an image of the visitor using the imaging device. The front door slave unit 7 transmits data of the captured image to the intercom main unit 10. Furthermore, the front door slave unit 7 transmits a control signal (call signal) to the intercom main unit 10 to call user U1. When a call can be established between the front door slave unit 7 and the intercom main unit 10 by performing a call start operation on the intercom main unit 10, the front door slave unit 7 transmits sound data to the intercom main unit 10. When the front door slave unit 7 receives sound data including the voice of the operator of the intercom main unit 10, it outputs sound (including the operator's voice) based on the received data.

[0038] The display unit 16 displays images transmitted from the lobby intercom 9 and the entrance slave unit 7. The display unit 16 is, for example, a touch panel, and displays an operation screen that is part of the operation unit 19 described later.

[0039] 2, the operation unit 19 includes a call-related button 191, an unlock button 192, a home button 193, an end button 194, and an alarm-related button 195. Furthermore, as described above, the operation unit 19 includes an operation screen that is displayed on the display unit 16. The operation screen will be described in detail in "(2.2) Operation Screen."

[0040] The operation unit 19 accepts operations by the user U1. When the fourth communication unit 14 receives a control signal (call signal) for calling the user U1 from the lobby intercom 9 and, for example, a pressing operation is performed on the call-related button 191, the intercom base unit 10 and the lobby intercom 9 become available for communication. If the operation unit 19 includes a touch panel, the operation of pressing the operation unit 19 includes, for example, an operation of touching the screen of the touch panel (touch operations such as tapping and swiping). Furthermore, if the call-related button 191 is pressed again when the call is available, the call ends. In other words, communication between the intercom base unit 10 and the lobby intercom 9, which is the call source, ends.

[0041] When the fourth communication unit 14 is receiving a call signal from the lobby interphone 9 or is able to communicate with the lobby interphone 9, for example, if the unlock button 192 is pressed, an unlock signal is transmitted to the shared control system 8. At this time, the shared control system 8 unlocks the door to the lobby.

[0042] Furthermore, when the call-related button 191 is pressed while the fifth communication unit 15 is receiving a control signal (call signal) for calling the user U1 from the front door slave 7, a call is made possible between the intercom master unit 10 and the front door slave 7. When the call-related button 191 is pressed again while a call is possible, the call is ended. In other words, the communication between the intercom master unit 10 and the front door slave 7, which is the call source, is ended.

[0043] The home button 193 is operated when a home screen G1 (see FIG. 3) described later is to be displayed on the display unit 16. The end button 194 is operated when the display of an image on the display unit 16 is to be ended.

[0044] The communication unit 17 includes a speaker and a microphone, and is configured to be able to communicate with the lobby interphone 9 and the entrance slave unit 7.

[0045] The alarm sound-related button 195 is operated when stopping the issuance of an alarm. For example, the alarm sound-related button 195 is operated when the detection result of the detection system 6 is a false alarm. When the user U1 presses the alarm sound-related button 195, for example, the alarm being issued from the detection system 6 is stopped.

[0046] The memory unit 20 is configured with a device selected from a ROM (Read Only Memory), a RAM (Random Access Memory), an EEPROM (Electrically Erasable and Programmable Read Only Memory), etc. The memory unit 20 stores data of images captured by the lobby intercom 9 and data of collected audio. The memory unit 20 stores data of images captured by the front door slave unit 7 and data of collected audio. The memory unit 20 stores data related to the operation screen to be displayed by the display unit 16.

[0047] The control unit 18 includes, for example, a computer system having a processor and a memory. The computer system functions as the control unit 18 when the processor executes a program stored in the memory.

[0048] The control unit 18 controls the communications of the first communication unit 11 to the fifth communication unit 15.

[0049] When the control unit 18 receives a control signal (call signal) and an image from the lobby interphone 9 via the fourth communication unit 14, it outputs sound data of the call sound to the speaker of the communication unit 17 and outputs the image to the display unit 16.

[0050] When the user U1 performs, for example, a pressing operation on the unlock button 192, the control unit 18 transmits an unlock signal to the shared control system 8 via the fourth communication unit 14.

[0051] When the control unit 18 receives a control signal (call signal) and an image from the front door unit 7 via the fifth communication unit 15, it outputs sound data of the call sound to the speaker of the call unit 17 and outputs the image to the display unit 16.

[0052] When the intercom master unit 10 is in answering mode and there is communication from the lobby intercom 9, front door sub-unit 7, etc., the control unit 18 stores information acquired by the communication in the memory unit 20. For example, when the control unit 18 receives a call signal from the lobby intercom 9 or front door sub-unit 7, it stores image data captured at the sender of the call signal and audio data collected at the sender in the memory unit 20. If the lobby intercom 9 does not have an imaging device, only audio data is received from the lobby intercom 9 and stored in the memory unit 20. Similarly, if the front door sub-unit 7 does not have an imaging device, only audio data is received from the front door sub-unit 7 and stored in the memory unit 20.

[0053] The control unit 18 periodically acquires weather information from, for example, an external weather server, and stores the acquired weather information in the storage unit 20.

[0054] The control unit 18 generates an operation screen in response to an operation on the intercom master unit 10, and displays the generated operation screen on the display unit 16. The control unit 18 controls processing related to the transition of the operation screen to be displayed on the display unit 16. The control unit 18 also controls the display unit 16 so that the display unit 16 displays the operation screen to be displayed.

[0055] The control unit 18 performs processing related to the playback of images (playback of moving images) and audio output stored in the storage unit 20. Specifically, the control unit 18 performs processing related to the playback of unplayed images among the images stored in the storage unit 20 and audio output.

[0056] (2.1.2) Control System The control system 3 that controls the multiple second devices 5 is, for example, a controller of an energy management system that manages the energy usage state in the dwelling unit F2. As shown in FIG. 1 , the control system 3 includes a first communication unit 31, a second communication unit 32, and a control unit 33.

[0057] The first communication unit 31 communicates with the intercom master unit 10. Specifically, the first communication unit 31 communicates with the second communication unit 12 of the intercom master unit 10 using a wireless communication method, for example, wireless communication. In this embodiment, the wireless communication method is a method that complies with standards such as Wi-Fi (registered trademark), Bluetooth (registered trademark), ZigBee (registered trademark), or low-power radio that does not require a license (specified low-power radio). Note that the first communication unit 31 and the second communication unit 12 may also communicate via wired communication.

[0058] The second communication unit 32 has a function of communicating with the communication units 51 of the plurality of second devices 5 by wired communication or wireless communication. The second communication unit 32 communicates with the communication units 51 (described later) of the second devices 5 by a communication method conforming to the ECHONET (Energy Conservation & Homecare Network: ECHONET (registered trademark)) standard, for example. Note that the communication method between the second communication unit 32 and the communication units 51 of the second devices 5 is not limited to the communication method conforming to the ECHONET standard, and can be changed as appropriate.

[0059] The control unit 33 has, for example, a computer system having a processor and a memory. The processor executes a program stored in the memory, causing the computer system to function as the control unit 33. The control unit 33 controls communication between the first communication unit 31 and the second communication unit 32.

[0060] For example, if the information received by the first communication unit 31 from the intercom master unit 10 includes command information for checking the status of multiple second devices 5, the control unit 33 causes the second communication unit 32 to send commands to the multiple second devices 5 to cause the multiple second devices 5 to transmit their respective statuses.

[0061] Here, the information received from the intercom master unit 10 may include control-related information relating to the control content of the plurality of second devices 5. The control-related information is information associated with a control command to be output to one or more second devices 5 to operate the one or more second devices 5 in a setting state suited to a desired scene (for example, a scene in the life of user U1 in dwelling unit F2, such as sleeping or going out). When the control system 3 receives the control-related information, the second communication unit 32 of the control system 3 transmits a control command to the communication unit 51 of the second device 5 to control the second device 5 based on the control-related information. Note that the control-related information may be information associated with a control command to collectively switch the operating states of the plurality of second devices 5 to a desired operating state (on or off), and the content of the control-related information can be changed as appropriate.

[0062] (2.1.3) First device In this embodiment, the two first devices 4 provided in the facility F1 are, for example, an electric lock system 42 that controls locking and unlocking of the entrance door of the dwelling unit F2 and an elevator system 41 provided in the shared facility F3.

[0063] As shown in FIG. 1, the electric lock system 42 includes an electric lock 421 and an electric lock control unit 422.

[0064] The electric lock control unit 422 locks or unlocks the electric lock 421 in response to a contact signal input from the first communication unit 11 of the intercom master unit 10.

[0065] As shown in FIG. 1, the elevator system 41 includes an elevator 411 and an elevator control unit 412.

[0066] When the elevator control unit 412 receives instructions regarding the control of the elevator 411 from the first communication unit 11 of the intercom base unit 10 via the shared control system 8, it moves the elevator 411 to the floor instructed by the intercom base unit 10 (for example, the floor where the dwelling unit F2 in which the intercom base unit 10 is installed is located).

[0067] (2.1.4)Second device The second devices 5 are, for example, electrical devices provided in the dwelling unit F2. The types and number of the second devices 5 are determined by the user U1 of the dwelling unit F2, and therefore the types and number of the second devices 5 may vary for each of the dwelling units F2 included in the facility F1. In this embodiment, the second devices 5 include, for example, at least one of a lighting device, an air conditioning control device, a cooking appliance, a hot water supply system, a heating system, a power generation system, and a power storage system.

[0068] Each of the second devices 5 includes a communication unit 51, a control unit 52, and a function unit 53.

[0069] The communication unit 51 communicates with the second communication unit 32 of the control system 3 by wireless communication or wired communication. The communication method adopted by the communication unit 51 can be changed as appropriate.

[0070] The control unit 52 includes, for example, a computer system having a processor and a memory. The processor executes a program stored in the memory, causing the computer system to function as the control unit 52. The control unit 52 controls the function unit 53.

[0071] The functional unit 53 is a component for realizing the respective functions of the multiple second devices 5. For example, if the second device 5 is an air conditioning control device, the functional unit 53 is a component for realizing the air conditioning function (such as a compressor, a heat exchanger, and a fan). If the second device 5 is a lighting device, the functional unit 53 is a component for realizing the lighting function (such as a light source and its lighting circuit). If the information received by the communication unit 51 from the control system 3 is a control command for controlling the second device 5, the control unit 52 controls the functional unit 53 and the communication unit 51 based on the control command. If the information received by the communication unit 51 from the control system 3 is a request for transmission of the status of the second device 5, the control unit 52 acquires the status of the functional unit 53 and causes the communication unit 51 to transmit status information indicating the status of the functional unit 53 to the control system 3.

[0072] (2.2) Operation screen The following describes each of the multiple operation screens that the intercom master unit 10 displays on the display unit 16. Note that the reference symbols and dashed lines surrounding areas in Figures 1 to 21 are shown for explanatory purposes only and are not displayed on the actual operation screens.

[0073] (2.2.1) Home screen First, the home screen G1 will be described with reference to FIG.

[0074] Home screen G1 is an operation screen that is displayed on display unit 16 when a predetermined operation is performed on intercom master unit 10. For example, when home button 193 (see FIG. 2) is pressed, home screen G1 is displayed on display unit 16. In other words, when home button 193 is pressed, control unit 18 of intercom master unit 10 generates home screen G1 and displays the generated home screen G1 on display unit 16.

[0075] As shown in FIG. 3, the home screen G1 includes display areas R1 to R9.

[0076] Display area R1 displays acquired information acquired through communication between intercom master unit 10 and communication terminals including front door sub-unit 7 and lobby intercom 9. Specifically, display area R1 displays an image (captured image) P1 acquired through communication with one of the communication terminals of front door sub-unit 7 and lobby intercom 9 during away mode as acquired information. Note that the acquired information displayed as image P1 is not limited to information acquired during away mode. For example, when user U1 of dwelling unit F2 is at home but does not answer a call, an image acquired through communication regarding the call may be displayed as image P1.

[0077] In addition to the image P1, the display region R1 also displays an image P2 for instructing playback and date and time information P3 indicating the date and time when the image P1 was captured.

[0078] When the intercom master unit 10 acquires multiple pieces of acquired information from one communication terminal in away mode, or acquires acquired information from each of two or more communication terminals, the most recent acquired information among the acquired acquired information is displayed in the display area R1.

[0079] In the display area R1, when information acquired through communication with at least one of the multiple communication terminals has not yet been played, viewed, or listened to, an icon M1 representing unread information indicating that the information has not been played (unread) is also displayed. For example, when there is a record of a visitor and there is no unplayed (unread) information, the icon M1 is not displayed, and the latest information among the played information is displayed as an image P1 in the display area R1. In addition, when there is a record of a visitor and there is unplayed (unread) information, the icon M1 is displayed, and the latest information among the unplayed information is displayed as an image P1 in the display area R1. The icon M1 may be displayed flashing or lit.

[0080] Display area R2 displays, for example, a rectangular operation unit B1, which is an icon for viewing or listening to information acquired by intercom master unit 10 through communication with at least one of the multiple communication terminals. By, for example, pressing operation on operation unit B1, character strings related to the content to be executed by intercom master unit 10 are displayed on operation unit B1. In this embodiment, the character string "View Record" is displayed on operation unit B1.

[0134] The operating status display section B39 of the air conditioning operation section B34 displays the operating status of the air conditioning control device 57. In this example, the air conditioning control device 57 is in operation, and the operating status display section B39 of the air conditioning operation section B34 displays the character string "In Operation."

[0135] The information displayed in the environment display section B37, the operation mode display section B38, and the operation status display section B39 of the air conditioning operation section B34 can be updated to the latest status by, for example, pressing the update operation section B43, which is, for example, a square-shaped icon displayed in the display area R24.

[0136] The operation switching operation section B40 of the air conditioning operation section B34 is an icon for switching between operating and stopped the air conditioning control device 57. The operation switching operation section B40 of the air conditioning operation section B34 displays the control content for the air conditioning control device 57 when, for example, a pressing operation is performed. In FIG. 8, the air conditioning control device 57 is in operation, so the operation switching operation section B40 of the air conditioning operation section B34 displays the character string "Stop." Here, when the user U1 performs, for example, a pressing operation on the operation switching operation section B40 of the air conditioning operation section B34, the operation of the air conditioning control device 57 is stopped.

[0137] The timer operation section B41 of the air conditioning operation section B34 is an icon for setting the timer of the air conditioning control device 57. Here, when the user U1 performs, for example, a pressing operation on the timer operation section B41 of the air conditioning operation section B34, the operation screen displayed on the display unit 16 transitions from the air conditioning setting screen G42 to a timer setting screen for setting the timer.

[0138] The detailed operation section B42 of the air conditioning operation section B34 is an icon for making detailed settings related to the operating conditions of the air conditioning control device 57. Here, when the user U1 performs, for example, a pressing operation on the detailed operation section B42 of the air conditioning operation section B34, the operation screen displayed on the display unit 16 transitions from the air conditioning setting screen G42 to a detailed operation screen G43, which is one of the multiple control system screens G4.

[0139] As shown in FIG. 9, the detailed operation screen G43 includes display areas R25 to R29.

[0140] The display area R25 displays the character string "Detailed Operation [Living Room Air Conditioner]." This allows the user U1 to recognize that the operation screen currently displayed on the display unit 16 is the detailed operation screen G43, which is one of the multiple control system screens G4.

[0141] The display area R26 displays the text "Device Control > Air Conditioner > Detailed Operation [Living Room Air Conditioner]." This allows the user U1 to recognize that the detailed operation screen G43 currently displayed on the display unit 16 is the control system screen G4, which is at a lower level than the air conditioning setting screen G42.

[0142] The display area R27 displays an operation unit B44 that is operated to display, on the display unit 16, for example, the device control screen G41, which is the control system screen G4 before transitioning to the detailed operation screen G43. The operation unit B44 is, for example, a square icon. For example, the character string "Back" is displayed in the operation unit B44.

[0143] The display region R28 displays a control item display section B45 that shows multiple control items that can be controlled by the air conditioning control device 57. The control item display section B45 is displayed in a table format with, for example, four rows and three columns. The first to fourth rows of the leftmost column C1 display, for example, four control items that can be controlled by the air conditioning control device 57 (e.g., "operation mode," "temperature," "air volume," and "air direction"). Here, control of the "operation mode" refers to switching the operation mode of the air conditioning control device 57 between cooling, heating, dry, etc. The first to fourth rows of the central column C2 display the current settings corresponding to the control items displayed in the first to fourth rows of column C1. The first to fourth rows of the rightmost column C3 display change operation sections B46 to B49 for changing the settings displayed in the first to fourth rows of column C2. In this embodiment, the character string "change" is displayed in each of the change operation sections B46 to B49.

[0144] The display area R29 displays a setting transmission operation section B50, which is, for example, a rectangular icon, for reflecting changes to the settings of the control items in the control of the air conditioning control device 57. In this embodiment, the setting transmission operation section B50 displays the character string "Send Settings." When the user U1 performs, for example, a pressing operation on the setting transmission operation section B50, the changes to the settings of the control items (for example, a change to the operation mode using the change operation section B46) are sent to the communication section of the air conditioning control device 57 (the communication section 51 of the second device 5 in FIG. 1). When the communication section of the air conditioning control device 57 receives the changes to the settings of the control items, the control section of the air conditioning control device 57 (the control section 52 of the second device 5 in FIG. 1) starts controlling the air conditioning control device 57 based on the changes to the settings of the control items.

[0145] By adopting the configuration of the plurality of control system screens G4 as described above, the following advantages are obtained.

[0146] For example, as shown in FIG. 4, the control item (first control item) that can be controlled for the air conditioning control device 57 and that is displayed on the second operation section B23 is one item: switching between stop and operation.

[0147] Meanwhile, the number of control items (second control items) that can be controlled by the air conditioning control device 57, which are shown on the multiple control system screens G4, is six in this embodiment, which is more than the number of first control items. Specifically, the second control items shown on the multiple control system screens G4 are two items on the air conditioning setting screen G42, namely, stop / operation switching and timer setting (see FIG. 8), and four items on the detailed operation screen G43, namely, operation mode control, temperature control, air volume control, and air direction control (see FIG. 9).

[0148] This allows the second device 5, for example the air conditioning control device 57, to be controlled in more detail on the multiple control system screens G4.

[0149] Here, the characteristics of the transition between the individual control screen G31 and the control system screen G4 in this embodiment will be further described.

[0150] The multiple control system screens G4 include screens that are not directly related to the detailed control of the second device 5 (for example, a control home screen that is the home screen of the control system 3, etc.). For example, when transitioning from the control home screen to a control system screen G4 for performing detailed control of the second device 5 (for example, a device control screen G41), a menu operation section for transitioning to the control home screen is displayed on the device control screen G41. On the other hand, when transitioning from the individual control screen G31 to the device control screen G41, for example, the menu operation section is not displayed on the device control screen G41, as shown in FIG. 7. In detail, when transitioning from the individual control screen G31 to the device control screen G41, the intercom master unit 10 sends an instruction to the control system 3 not to display the menu operation section on the device control screen G41. In response to this, the control system 3 generates a device control screen G41 that does not display the menu operation section and displays it on the display unit 16. The control system 3 may generate and store in advance a device control screen G41 on which the menu operation unit is displayed and a device control screen G41 on which the menu operation unit is not displayed. In this case, when the control system 3 receives a display request for the device control screen G41 from the intercom master unit 10, it selectively displays the device control screen G41 on which the menu operation unit is not displayed on the display unit 16.

[0151] Furthermore, when transitioning from the control home screen to, for example, the device control screen G41, the operation unit B19 is not displayed on the device control screen G41. On the other hand, when transitioning from, for example, the individual control screen G31 to the device control screen G41, the operation unit B19 is displayed as described above, and by performing, for example, a pressing operation on the operation unit B19, the operation screen transitions to the individual control screen G31. In detail, when transitioning from the individual control screen G31 to the device control screen G41, the intercom master unit 10 sends an instruction to the control system 3 to display the operation unit B19 on the device control screen G41. In response to this, the control system 3 generates a device control screen G41 on which the operation unit B19 is displayed and displays it on the display unit 16. Note that the control system 3 may previously generate and store a device control screen G41 on which the operation unit B19 is not displayed and a device control screen G41 on which the operation unit B19 is displayed. In this case, when the control system 3 receives a display request for the device control screen G41 from the intercom master unit 10, it causes the display unit 16 to selectively display the device control screen G41 on which the operation section B19 is displayed.

[0152] This reduces the possibility that the user U1 will be unable to return from the control system screen G4 for performing detailed control of the second device 5 to the individual control screen G31.

[0153] (2.2.4) Group control screen The group control screen G32 is the control screen G3 that is displayed on the display unit 16 when, for example, a pressing operation is performed on the group control tab B17 in the display region R14 of the individual control screen G31.

[0154] As shown in FIG. 6, the group control screen G32 includes display areas R30 to R34.

[0155] The display region R30 displays a plurality of display target operation units, which are rectangular icons with different display modes. In the display region R30, the plurality of display target operation units include a plurality (seven in this embodiment) of third operation units B60 (B61 to B67). Here, each of the third operation units B61 to B67 is operated to control one or more third devices selected from, for example, two first devices 4 (electric lock system 42, elevator system 41) and, for example, five second devices 5 (lighting devices 54 to 56, air conditioning control devices 57, 58). In other words, the group control screen G32 is an operation screen for collectively controlling one or more third devices.

[0156] In this embodiment, the symbols and names (character strings) written on each of the third operation sections B61 to B67 are different. Specifically, each of the third operation sections B61 to B67 displays a name representing one or more third devices to be controlled, a character string and a symbol representing the purpose of control, etc.

[0157] For example, the third operation section B61 is a display target operation section for collectively controlling the air conditioning control devices 57 and 58 registered as the third devices.

[0158] The third operation unit B62 is a display target operation unit for controlling the third equipment related to ensuring the safety of the dwelling unit F2 when the dwelling unit F2 is left unoccupied for a long period of time, for example, due to user U1 traveling.

[0159] The third operation section B63 is a display target operation section for collectively controlling, for example, the lighting devices 54 to 56 registered as third devices.

[0160] The third operation section B64 is a display target operation section for performing control related to putting the third device into a state suitable for the user U1 to sleep, for example.

[0161] The third operation section B65 is a display target operation section for controlling a third device related to ensuring the safety of the dwelling unit F2 while the user U1 is out, for example.

[0162] The third operation section B66 is a display target operation section for performing control related to setting the third device to a state suitable for the user U1 when waking up, for example.

[0163] The third operation section B67 is a display target operation section for performing control related to setting the third device in a state suitable for the user U1 when at home, for example.

[0164] Here, as an example, a third operating section B64 for performing control related to making the dwelling unit F2 suitable for sleeping for the user U1 will be described.

[0165] The third operation unit B64 is operated to control, for example, the electric lock system 42, the lighting devices 54 to 56, and the air conditioning control devices 57 and 58. Here, before the third operation unit B64 is operated, as shown in Figures 4 and 5, it is assumed that the electric lock 421 of the electric lock system 42 is unlocked, the lighting device 54 (kitchen light) and the lighting device 55 (living room light) are on, and the air conditioning control device 57 (living room air conditioner) is operating. It is also assumed that the air conditioning control device 58 (bedroom air conditioner) is stopped, and the lighting device 56 (bedroom main light) is off.

[0166] The third operation section B64 displays, from the top, a symbol of a bed and the character string "Go to bed," which represent going to bed.

[0167] For example, when the third operation unit B64 is pressed, the electric lock 421 that was unlocked is locked, the lighting devices 54 and 55 that were turned on are turned off, and the air conditioning control device 57 that was running is stopped. The air conditioning control device 58 that was stopped is started, and the lighting device 56 that was turned off is turned on. After the third operation unit B64 is pressed, the third operation unit B64 may display, for example, a string of characters "Sleep Mode." The display color of the third operation unit B64 may also change from that before the pressing operation. At this time, the lighting device 56 may be turned on in a night light mode with lower illuminance than when it is normally turned on. By pressing the third operation unit B64 in this way, the state of the dwelling unit F2 becomes suitable for the user U1 to sleep, without the user U1 having to individually control the third devices (the electric lock system 42, the lighting devices 54-56, and the air conditioning control devices 57 and 58).

[0168] Furthermore, when the third operation unit B64 is pressed again, for example, the lighting devices 54 and 55 are turned on and the air conditioning control device 57 starts operating. Also, the air conditioning control device 58 is stopped operating and the lighting device 56 is turned off. In this case, for example, the electric lock 421 is controlled to remain locked for security purposes.

[0169] The one or more third devices controlled by the operations of the third operation units B61 to B67 can be changed as appropriate by, for example, the user U1.

[0170] When, for example, a pressing operation is performed on the additional operation unit B68, which is, for example, a square icon displayed in the display area R31, the operation screen displayed on the display unit 16 transitions from the group control screen G32 to an operation unit addition screen. On the operation unit addition screen, the user U1 can set a new third operation unit B60 for controlling any one or more third devices. The newly set third operation unit B60 is added to the display area R30.

[0171] In the display area R32, an operation unit B69 is displayed that is operated to display, for example, the home screen G1, which is an operation screen before transitioning to the control screen G3 (individual control screen G31 and group control screen G32), on the display unit 16. In this embodiment, the operation unit B69 is, for example, a square icon. In this embodiment, the character string "Back" is displayed in the operation unit B69.

[0172] Display region R33 displays a switching operation section B70 that is operated to switch the page displayed in display region R30. The switching operation section B70 has the same function as the switching operation section B13 displayed on individual control screen G31, and therefore a description thereof will be omitted.

[0173] The display region R34 displays an individual control tab B16 and a group control tab B17. The individual control tab B16 and the group control tab B17 were explained in "(2.2.2) Individual Control Screen," so explanation will be omitted here.

[0174] (2.2.5) Display when operation of the display target operation part is restricted The following describes restrictions on the operation of the display target operation section on the control screen G3 (individual control screen G31 and group control screen G32).

[0175] Here, it is assumed that the second operation unit B21 displayed on page Pg1 of the individual control screen G31 is operated as shown in Fig. 4. As described above, the second operation unit B21 is a displayed operation unit operated to control the lighting device 54 (kitchen lighting), and in Fig. 4, the lighting device 54 is on.

[0176] At this time, when, for example, a pressing operation is performed on the second operation unit B21, as shown in FIG. 1, control information instructing the second device 5, i.e., the lighting device 54, to turn off the light is transmitted from the intercom master unit 10 via the control system 3. At this time, as shown in FIG. 10, for example, the character string "TRANSMITTING" is displayed in the status display area A13 of the second operation unit B21. Furthermore, in the portion of the second operation unit B21 where the symbol of the lighting device was displayed, an indicator 22 including, for example, multiple circles that rotate is displayed. The character string "TRANSMITTING" and the indicator 22 continue to be displayed on the second operation unit B20 from the time the second operation unit B20 is operated until the control prohibition period has elapsed. The control prohibition period will be described in detail later.

[0177] The intercom master unit 10 does not accept any operation of the second operation unit B20 until the control prohibition period has elapsed since the second operation unit B20 was operated. If the second operation unit B20 is operated during the control prohibition period, information notifying the user U1 that the operation of the second operation unit B20 will not be accepted is displayed on the display unit 16. For example, in this embodiment, if the second operation unit B21 is pressed during the control prohibition period, the second operation unit B21 is displayed in gray, notifying the user U1 that the operation of the second operation unit B21 will not be accepted. Note that the second operation unit B21 may be displayed in gray when a control signal instructing the lighting device 54 to turn off is transmitted. In other words, the second operation unit B21 may be displayed in gray at the same time that the character string "Sending" and the indicator 22 are displayed.

[0178] In this embodiment, during the control prohibition period of the second operation unit B21, the intercom master unit 10 accepts operations of the display target operation units other than the second operation unit B21. For example, during the control prohibition period of the second operation unit B21, the intercom master unit 10 accepts operations of the first operation units B11 and B12 and the second operation units B22 to B25 included in the pages Pg1 and Pg2 (see FIGS. 4 and 5) displayed in the display area R10 of the individual control screen G31.

[0179] During the control prohibition period of the second operation unit B21, only the third operation unit B60, which does not include the lighting device 54 as a control target among the third operation units B61 to B67 displayed on the group control screen G32 (see FIG. 6), can be operated. In other words, during the control prohibition period of the second operation unit B21, the intercom master unit 10 does not accept operation of the third operation unit B60, which includes the lighting device 54, which is the control target of the second operation unit B21, as a third device among the third operation units B61 to B67. For example, when the third operation unit B64, which is operated to control the electric lock system 42, the lighting devices 54 to 56, and the air conditioning control devices 57 and 58, is operated on the group control screen G32, a notification message 23 stating, for example, "Operation is not possible because the device is being operated or set up," and a confirmation operation unit B71 displaying the character string "Confirm," are displayed on the display unit 16, as shown in FIG. 11. This causes intercom master unit 10 to notify user U1 that operation of third operation unit B64 will not be accepted.

[0180] When the user U1 presses the confirmation operation section B71, for example, the notification message 23 and the confirmation operation section B71 are hidden and the group control screen G32 is displayed on the display unit 16.

[0181] In this embodiment, the control prohibition period is a period that includes the transmission period and the operation check period.

[0182] The transmission period is the period from when intercom master unit 10 transmits control information instructing the lighting device 54 to turn off the light to when the lighting device 54 receives the control information. Specifically, the control information is transmitted from intercom master unit 10 to control system 3 (see FIG. 1 ). Upon receiving the control information, control system 3 transmits the control information to the lighting device 54, which is the second device 5. Upon confirming that the lighting device 54 has received the control information, control system 3 transmits a reception confirmation signal to intercom master unit 10. By receiving the reception confirmation signal transmitted from control system 3, intercom master unit 10 can confirm that the lighting device 54 has received the control information. In other words, in this case, the transmission period is the period from when intercom master unit 10 transmits control information instructing the lighting device 54 to turn off the light to when intercom master unit 10 receives the reception confirmation signal transmitted from the control system 3.

[0183] The operation confirmation period is the period after the transmission period until intercom master unit 10 confirms that lighting device 54 has been turned off as instructed in the control information. In detail, after the transmission period, intercom master unit 10 transmits a confirmation instruction signal to control system 3 to check the operating status of lighting device 54. Note that the time from the end of the transmission period until intercom master unit 10 transmits the confirmation instruction signal is shorter than the predetermined period (e.g., 5 seconds) during which the status of lighting device 54 displayed in status display area A13 is updated.

[0184] When the control system 3 receives the confirmation instruction signal transmitted from the intercom master unit 10, it checks the operating status of the lighting device 54. If it is confirmed that the lighting device 54 is turned off as instructed by the control information, the control system 3 transmits a confirmation signal to the intercom master unit 10.

[0185] By receiving the confirmation signal transmitted from the control system 3, the intercom master unit 10 can confirm that the lighting device 54 has been turned off as instructed by the control information. Note that the control system 3 may be configured to automatically check the operating status of the lighting device 54 and transmit a confirmation signal to the intercom master unit 10, without relying on receiving a confirmation instruction signal from the intercom master unit 10.

[0186] When the control prohibition period for the second operation unit B21 has elapsed, the intercom master unit 10 resumes accepting operations of the second operation unit B21. When the control prohibition period has elapsed, the second operation unit B21 displays the symbol of the lighting device and the character string "ON" as the control content to be executed when the second operation unit B21 is operated, as shown in Fig. 12. In addition, the character string "OFF" is displayed in the status display area A13.

[0187] The transmission period may be the control prohibition period. In this case, when the intercom master unit 10 receives a reception confirmation signal transmitted from the control system 3, it resumes accepting operations of the second operation unit B21.

[0188] (2.2.6) Display when an abnormality is detected The following describes the screen that is displayed on the display unit 16 when the detection system 6 (see FIG. 1) installed in the dwelling unit F2 detects an abnormality in the dwelling unit F2. Here, the description will be made assuming that the detection system 6 is a gas detector (hereinafter referred to as gas detector 6).

[0189] When gas detector 6 detects a gas leak in dwelling unit F2, it transmits abnormality information indicating the occurrence of a gas leak to third communication unit 13 (see FIG. 1). When third communication unit 13 receives the abnormality information, intercom master unit 10 stops accepting operations from first operation units B11, B12, second operation units B21 to B25, and third operation units B61 to B67. Note that at this time, intercom master unit 10 may be set to stop accepting operations from first operation units B11, B12, second operation units B21 to B25, and third operation units B61 to B67, and to control the devices that are the control targets of first operation units B11, B12 and second operation units B21 to B25. For example, intercom master unit 10 may stop accepting operations from first operation units B11, B12, second operation units B21 to B25, and third operation units B61 to B67, and may also turn off lighting devices 54 to 56 operated by second operation units B21 to B25, and stop operation of air conditioning control devices 57, 58. Note that the control content to be performed by intercom master unit 10 when abnormality information is received can be set arbitrarily.

[0190] When the intercom base unit 10 stops accepting operations on the first operation units B11, B12, the second operation units B21 to B25, and the third operation units B61 to B67, the display unit 16 displays a notification message 24, for example, "Operation is not possible because an alarm has been issued," and a confirmation operation unit B72 with the string "Confirm" displayed, as shown in Figure 13.

[0191] At this time, when the user U1 presses the confirmation operation unit B72, for example, the home screen G1 (see FIG. 3) is displayed on the display unit 16. At this time, the alarm notification unit B7 of the home screen G1 displays the character string "ALARM" to notify that an abnormality has been detected by the gas detector 6.

[0192] Here, intercom master unit 10 will not accept operations on first operation units B11, B12, second operation units B21 to B25, and third operation units B61 to B67 until a predetermined condition is met. The predetermined condition is, for example, that third communication unit 13 receives information indicating that gas leak in dwelling unit F2 is no longer detected from gas detector 6. The predetermined condition may be, for example, that user U1 presses alarm sound-related button 195 (see FIG. 2), which is a mechanical button provided on intercom master unit 10.

[0193] (2.2.7) Startup screen settings Below, we will explain how to set up the startup screen that is displayed on display unit 16 when user U1 touches display unit 16 while intercom master unit 10 is in a standby state with nothing displayed on display unit 16.

[0194] In this embodiment, if the operation unit 19 (see FIG. 2 ), which includes the call-related button 191, the unlock button 192, the home button 193, the end button 194, and the alarm sound-related button 195, and the operation screen displayed on the display unit 16 are not operated for a certain period of time (e.g., 30 seconds), the intercom master unit 10 enters a standby state. In this state, when the user U1 touches the display unit 16, a start-up screen is displayed on the display unit 16. Here, in this embodiment, the start-up screen can be selected from a plurality of candidate operation screens.

[0195] The procedure for selecting the startup screen will be described below.

[0196] The startup screen is initially set to, for example, the home screen G1 (see FIG. 3).

[0197] First, the user U1 presses the operation unit B8 displayed on the home screen G1 to change the startup screen from the home screen G1. When the operation unit B8 is pressed, the operation screen displayed on the display unit 16 transitions from the home screen G1 to a user setting screen G2 for configuring settings for the intercom master unit 10 and the control system 3.

[0198] Here, the user setting screen G2 includes display areas R35 to R38, as shown in FIG.

[0199] The character string "Settings" is displayed in the display region R35, which allows the user U1 to recognize that the operation screen currently displayed on the display unit 16 is the user setting screen G2.

[0200] In the display area R36, an operation unit B73 is displayed, which is operated to display, on the display unit 16, for example, the home screen G1, which is an operation screen before transitioning to the user setting screen G2. The operation unit B73 is, for example, a square icon. For example, the character string "Back" is displayed in the operation unit B73.

[0201] Display area R37 displays, for example, five setting operation sections B81 to B85 for selecting the type of setting content related to intercom master unit 10 and control system 3. Setting operation sections B81 to B85 are, for example, rectangular icons. Information indicating the type of setting content (name related to setting) and a graphic representing the type are displayed in setting operation sections B81 to B85.

[0202] For example, the setting operation section B81 displays "sound" as a name related to settings. The setting operation section B81 is pressed, for example, when setting a ring tone.

[0203] The setting operation section B82 displays "Call Call" as the name related to settings. The setting operation section B82 is pressed, for example, when setting an answering message to be displayed when a call is made during answering mode.

[0204] The setting operation section B83 displays "recording" as a name related to settings. The setting operation section B83 is pressed, for example, when making settings related to recording (settings such as recording time).

[0205] The setting operation section B84 displays "screen" as a name related to settings. The setting operation section B84 is pressed, for example, when making settings related to the screen (settings such as screen resolution).

[0206] The setting operation section B85 displays "EMS" as a name related to settings. The setting operation section B85 is pressed, for example, when performing settings related to the control system 3 (changing energy saving target values, etc.).

[0207] Next, the user U1 performs a pressing operation on the setting operation unit B83 to change the startup screen from the home screen G1. When the pressing operation is performed on the setting operation unit B83, for example, four screen setting operation units B91 to B94 for selecting the type of setting content for the screen are displayed in the display region R38.

[0208] Here, the screen setting operation sections B91 to B94 display information indicating the type of setting content (name of setting) and the current setting content, etc.

[0209] For example, the screen setting operation section B91 displays "brightness" as the setting name and "1" as the current screen brightness setting value. The screen setting operation section B91 is pressed, for example, when setting the screen brightness.

[0210] The screen setting operation section B92 displays "Start-up screen" as a name related to the setting and "Home" indicating the home screen as the setting content of the current startup screen. The screen setting operation section B92 is pressed, for example, when setting the startup screen.

[0211] The screen setting operation section B93 displays "Maintenance" as the name related to the setting. The screen setting operation section B93 is pressed, for example, when setting maintenance of the screen.

[0212] The screen setting operation section B94 displays the name of the setting, "Touch panel correction." The screen setting operation section B94 is pressed, for example, when setting the touch panel of the display section 16, for example.

[0213] Next, the user U1 performs a pressing operation on the screen setting operation unit B92 to change the startup screen from the home screen G1.

[0221] The startup screen candidate G13 lists "EMS home screen" as the name of the operation screen to be selected as the startup screen. Note that "EMS home screen" here refers to the control home screen of the control system 3.

[0222] In FIG. 15, the home screen G1 is selected as the startup screen, and the radio button RB1 of the startup screen candidate G11 is checked. The user U1 can check either the radio button RB2 of the startup screen candidate G12 or the radio button RB3 of the startup screen candidate G13, for example, by pressing the radio button. After checking either the radio button RB2 or the radio button RB3, the user can change the startup screen from the home screen G1 to the operation screen corresponding to the checked radio button by pressing the decision operation unit B96 displayed in the display area R43, for example. The decision operation unit B96 is, for example, a rectangular icon, and displays the character string "Confirm."

[0223] (2.2.8) English setting for the name of the second device The following describes how to set the name of the second device 5 in English.

[0224] In this embodiment, the operation screen displayed on the display unit 16 is displayed in a display language based on the display language setting of the intercom master unit 10. In addition, the display content related to the second device 5 on the operation screen is displayed in a display language based on the display language setting of the control system 3.

[0225] For example, if the display language setting of the intercom master unit 10 is English and the display language setting of the second device 5 in the control system 3 is Japanese, the display language setting of the individual control screen G31 will be a mixture of English and Japanese. In detail, as shown in Fig. 16 and Fig. 17, only the names of the lighting devices 54 to 56 and the air conditioning control devices 57 and 58, which are the second device 5, are displayed in Japanese.

[0226] When the display language setting of the intercom master unit 10 is English and the display language setting of the second device 5 is Japanese, the individual control screen G31 includes display areas R44 to R49, as shown in Figures 16 and 17. The content displayed in the display areas R44 to R48 is the same as the content displayed in the display areas R10 to R14 described in "(2.2.2) Individual control screen" except for the display language, so a description thereof will be omitted.

[0227] In the display region R49, a screen call operation section B97 and a name setting operation section B98 are displayed.

[0228] The screen call operation unit B97 is an operation unit in which the string "Detailed Operation" displayed on the screen call operation unit B18 in Figure 4 has been changed to the string "Control with EMS", and since its functions are the same as those of the screen call operation unit B18, its explanation will be omitted.

[0229] The name setting operation section B98 is, for example, a square-shaped icon that is operated to set the name of the second device 5 to be displayed on the display section 16. The name setting operation section B98 displays, for example, the character string "Name Setting."

[0230] The procedure for changing the display of the names of the lighting devices 54 to 56 and the air conditioning control devices 57 and 58 to English will be described below.

[0231] First, the user U1 presses the name setting operation unit B98, for example. When the name setting operation unit B98 is pressed, the operation screen displayed on the display unit 16 transitions from the individual control screen G31 to the device name setting screen G6. Note that the device name setting screen G6 is generated by, for example, the control unit 33 of the control system 3.

[0232] Here, the device name setting screen G6 includes display areas R50 to R52, as shown in FIG.

[0233] The display region R50 displays the character string "Device Name Setting." This allows the user U1 to recognize that the operation screen currently displayed on the display unit 16 is the device name setting screen G6.

[0234] Display region R51 displays a device name change operation section B99 for setting the name of the second device 5 controlled by control system 3. The device name change operation section B99 is displayed in, for example, a two-column table format. The first line of column C11 on the left side displays the string "Device Type." Starting from the second line, device types corresponding to the second devices 5 installed in dwelling unit F2, namely, lighting devices 54-56 and air conditioning control devices 57 and 58, are listed. The first line of column C12 to the right of column C11 displays the string "Device Name." Starting from the second line of column C12, names corresponding to lighting devices 54-56 and air conditioning control devices 57 and 58, respectively, are displayed: "Kitchen Light," "Living Room Light," "Bedroom Main Light," "Living Room Air Conditioner," and "Bedroom Air Conditioner." To the right of the names corresponding to lighting devices 54-56 and air conditioning control devices 57 and 58, respectively, edit operation sections B101-B105, each of which is a rectangular icon displaying the string "Edit." The editing operation sections B101 to B105 are pressed, for example, to change the names corresponding to the lighting devices 54 to 56 and the air conditioning control devices 57 and 58, respectively.

[0235] In the display region R52, an operation unit B106 is displayed which is operated to cause the display unit 16 to display, for example, the individual control screen G31, which is the operation screen before transitioning to the device name setting screen G6. The operation unit B106 is, for example, a square icon. For example, the character string "Back" is displayed in the operation unit B106.

[0236] The user U1, for example, presses one of the edit operation units B101 to B105 to change the name of the second device 5 displayed on the individual control screen G31 to English. When each of the edit operation units B101 to B105 is pressed, the name of the corresponding second device 5 can be changed. Here, as shown in FIG. 19, the user U1 changes the names corresponding to the lighting devices 54 to 56 and the air conditioning control devices 57 and 58 to, for example, "Kitchen Light," "LR Light," "BR Light," "LR A / C," and "BR A / C," respectively. As a result, the name of the second device 5 displayed on the individual control screen G31 is changed to English, as shown in FIGS. 20 and 21.
