Description

[Technical Field]

[0001] The present disclosure relates to a door phone master unit and a notification method. [Background technology]

[0002] BACKGROUND ART Conventionally, there has been known an intercom system (or door phone system) that issues a disaster information alarm to notify the occurrence of a natural disaster such as an earthquake or tsunami (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-293667 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned conventional technology, disaster information about a natural disaster is sent from the entrance handset of the intercom system to an outside alarm outside the residence. Therefore, even with such an intercom system, if an emergency disaster occurs, such as a collapsed or flooded house, it is not possible to know whether anyone remains inside the residence. Rescuers (rescue workers, neighbors, people passing by, etc.) may have to open doors and break windows one by one to enter the residence and check whether anyone remains. As a result, rescue efforts may take a long time. Furthermore, people who are unable to move as they wish due to illness or other reasons may not be able to respond to rescuers' calls, and they may be overlooked.

[0005] Non-limiting examples of the present disclosure contribute to providing an indoor phone master unit and a notification method that can increase the possibility of rescue when a disaster occurs. [Means for solving the problem]

[0006] A door phone master unit according to one embodiment of the present disclosure includes an acquisition unit that acquires status information indicating the activity status of devices present in a house and acquires time information indicating the time related to the occurrence of a disaster, a determination unit that determines whether or not a predetermined condition is met based on the status information and the time information, and a notification unit that, if the predetermined condition is met, notifies a door phone slave unit or a wireless mobile terminal registered to the unit of information indicating that there may be a person in the house.

[0007] In a notification method according to one embodiment of the present disclosure, a door phone master unit acquires status information indicating the activity status of devices present in a house, acquires time information indicating the time related to the occurrence of a disaster, determines whether or not a specified condition is met based on the status information and the time information, and if the specified condition is met, notifies a door phone slave unit or a wireless mobile terminal registered to the door phone master unit of information indicating that there may be a person in the house.

[0008] These comprehensive or specific aspects may be realized as a system, an apparatus, a method, an integrated circuit, a computer program, or a recording medium, or may be realized as any combination of a system, an apparatus, a method, an integrated circuit, a computer program, and a recording medium. [Effects of the Invention]

[0009] According to one embodiment of the present disclosure, when certain conditions are met, information indicating that there may be someone inside the house is notified to the door phone handset or wireless mobile terminal, thereby increasing the possibility of rescue in the event of a disaster.

[0010] Further advantages and benefits of an embodiment of the present disclosure will become apparent from the specification and drawings.

DETAILED DESCRIPTION OF THE INVENTION

[0012] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings as appropriate. However, more detailed explanation than necessary may be omitted. For example, detailed explanation of already well-known matters or redundant explanation of substantially identical configurations may be omitted. This is to avoid unnecessary redundancy in the following explanation and to facilitate understanding by those skilled in the art.

[0013] The accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0014] (Embodiment) <Door phone system> First, a door phone system according to an embodiment of the present disclosure will be described.

[0015] 1 is a system configuration diagram showing an example of the configuration of a door phone system 10 according to the present embodiment. In FIG. 1, the surrounding environment of the system configuration is also shown.

[0016] As shown in FIG. 1, the door phone system 10 includes, for example, a door phone master unit 100 placed inside a building (an example of a house) 30 that is the home of a user 20, a front door slave unit (which may also be called a door phone slave unit) 200 placed near a front door 31 (or a nameplate or mailbox) of the building 30, and an electric lock 300 installed on the front door 31.

[0017] Intercom master unit 100 includes, for example, a speaker, a display, a monitor button, a call button, a microphone, a disaster mode release button, and a lock / unlock button. Intercom master unit 100 is initially configured to pre-register front door slave unit 200 and electric lock 300. In addition to the function of responding to calls (starting calls), intercom master unit 100 also has the function of displaying video of the area around the front door transmitted from front door slave unit 200, the function of accepting lock / unlock operations for electric lock 300 of front door 31, and the function of notifying that someone may be at home (in building 30) (or that someone may have collapsed in building 30) in the event of a disaster, as well as the location within building 30 where the person may be.

[0018] The speaker outputs audio from the front door slave unit 200 to the outside of the intercom master unit 100, for example, when the intercom master unit 100 and the front door slave unit 200 are in a call state. The display displays, for example, an image captured by a camera of the front door slave unit 200. For example, when the monitor button is pressed, the camera of the front door slave unit 200 is activated and the image captured by the camera of the front door slave unit 200 begins to be displayed on the display. For example, when the call button is pressed, the intercom master unit 100 and the front door slave unit 200 are in a call state. The microphone collects sounds around the intercom master unit 100, for example. For example, when the disaster mode release button is pressed, the disaster mode, which is used to notify users that someone may be at home in the event of a disaster, is released and the intercom master unit 100 enters (transitions) into normal mode. For example, when the lock / unlock button is pressed, the electric lock 300 of the front door 31 is locked / unlocked.

[0019] Doorway slave unit 200 includes a call button, an LED (Light Emitting Diode), a speaker, a microphone, and a camera. A two-wire cable 201, for example, consisting of a pair of copper wires, is laid between doorway slave unit 200 and indoor apparatus 100. In addition to the calling and communication functions, doorway slave unit 200 also has the function of capturing video of the area around the entrance with a camera and transmitting the video to indoor apparatus 100. Doorway slave unit 200 and indoor apparatus 100 may communicate wirelessly according to, for example, the DECT (Digital Enhanced Cordless Telecommunications) protocol.

[0020] For example, when the call button is pressed, it sends a visitor notification to the indoor phone base unit 100. The LED flashes red to indicate an emergency situation in which a person may have collapsed. For example, when the front door slave unit 200 and the front door slave unit 100 are in a call state, the speaker outputs audio from the front door slave unit 100 to the outside of the front door slave unit 200. For example, the microphone collects sounds around the front door slave unit 200. For example, the camera captures video of the area around the front door.

[0021] Electric lock 300 is a key device that locks / unlocks front door 31 in response to a locking request (instruction) / unlocking request (instruction), which is an electric signal, in addition to normal key operation (operation using a physical key) into a keyhole. An electric lock code 301, which is, for example, a JEM-A standard code, is laid between electric lock 300 and indoor phone master unit 100. Electric lock 300 locks / unlocks under the control of indoor phone master unit 100.

[0022] The door phone system 10 also includes a communication router 400 located within the building 30, a wirelessly capable device 500 located within the building 30, a server 600 connected to a public network 610 such as the Internet, and a wireless terminal (which may be referred to as a wireless mobile terminal) 700 (hereinafter referred to as a smartphone 700) such as a smartphone or tablet that can be taken outside the building 30. The smartphone 700 includes a smartphone owned by the user 20 and a smartphone owned by a person other than the user 20 (for example, a family member or relative of the user 20).

[0023] Communication router 400 connects to indoor apparatus 100, smartphone 700, device 500, and public network 610 via wireless communication lines 401, 402, 403, and 404, respectively, and relays communications between indoor apparatus 100, smartphone 700, and device 500 and public network 610, and relays communications between indoor apparatus 100, smartphone 700, and device 500. Wireless communication lines 401, 402, and 403 may be, for example, Wi-Fi (registered trademark; hereinafter omitted) lines, and wireless communication line 403 may be, for example, a cellular (mobile) line such as an LTE (Long Term Evolution) line or an NR (New Radio) line. Alternatively, the door phone master unit 100, the smartphone 700, and the device 500 may be directly connected via a wireless communication line (for example, using the Wi-Fi Direct method, Bluetooth (registered trademark) method, etc.) without going through the communication router 400, and the communication router 400 may be connected to the public network 610 via a cable line, optical fiber line, etc. instead of the wireless communication line 404.

[0024] The device 500 includes, for example, a human sensor 501, a home appliance 502, and an equipment device 503 as shown in FIGS. 2 and 3 . The device 500 transmits status information indicating its own activity state together with the transmission date and time to the indoor phone master 100 via the wireless communication line 403 and the communication router 400 periodically or whenever the state changes. Examples of information transmitted by the device 500 to the indoor phone master 100 will be described later with reference to FIG. 6 . In addition to the device 500, the electric lock 300 also transmits status information indicating its activity state together with the transmission date and time to the indoor phone master 100 via the electric lock code 301 periodically or whenever the state changes. The smartphone 700 also transmits status information indicating its activity state together with the transmission date and time to the indoor phone master 100 via the wireless communication line 402 and the communication router 400 periodically or whenever the state changes.

[0025] Server 600 connects to communication router 400 via public network 610 or the like when intercom master unit 100 is powered on, etc., thereby connecting to intercom master unit 100 and registering intercom master unit 100. Thereafter, server 600 remains constantly connected to intercom master unit 100 via public network 610 or the like, and exchanges various information with intercom master unit 100. An encrypted communication path may be established between server 600 and intercom master unit 100, and server 600 may perform encrypted communication with intercom master unit 100. Server 600 may be referred to as an authentication server.

[0026] For example, server 600 performs authentication processing on smartphone 700 that has requested access to indoor phone master unit 100. Then, on the condition that authentication of smartphone 700 is successful, server 600 establishes a connection with smartphone 700 and relays communication between smartphone 700 and indoor phone master unit 100 (via communication router 400, etc.).

[0027] On the other hand, when the intercom master unit 100 requests access to the smartphone 700, the server 600 establishes a connection with the smartphone 700 without performing authentication processing, and relays communication between the smartphone 700 and the intercom master unit 100 (via the communication router 400, etc.).

[0028] For example, when smartphone 700 is located inside building 30, it connects to communication router 400 via wireless communication line 402 to access indoor phone base unit 100, and when smartphone 700 is located outside building 30, it connects to public network 610 via wireless communication line 601 and accesses indoor phone base unit 100 via server 600. Wireless communication line 601 may be, for example, a cellular (mobile) line such as an LTE line or an NR line. Smartphone 700 may perform encrypted communication with indoor phone base unit 100 from inside and outside building 30.

[0029] The smartphone 700 also includes a speaker, a touch panel display, a microphone, a (terminal) monitor button, a (terminal) call button, a (terminal) disaster mode release button, a (terminal) disconnect button, a (terminal) unlock button, and a (terminal) lock button. The (terminal) monitor button, the (terminal) call button, the (terminal) disaster mode release button, the (terminal) disconnect button, the (terminal) unlock button, and the (terminal) lock button may be image buttons (icons) displayed on a touch panel display that can be used on an application for using the functions of the door phone system 10.

[0030] The speaker outputs audio from the indoor phone base unit 100 to the outside of the smartphone 700, for example, when the smartphone 700 and the indoor phone base unit 100 are in a call state. The touch panel display displays, for example, an image captured by a camera of the front door slave unit 200, a (terminal) monitor button, a (terminal) call button, a (terminal) disconnect button, a (terminal) unlock button, a (terminal) lock button, and the like. When the (terminal) monitor button is pressed (tapped), for example, it starts outputting an image of the area around the front door transmitted from the front door slave unit 200 via the front door mobile unit 100. When the (terminal) call button is pressed (tapped), for example, it starts a call between the smartphone 700 and the front door slave unit 200 via the front door mobile unit 100. When the (terminal) disaster mode release button is pressed (tapped), for example, it releases the disaster mode described above and causes the front door slave unit 100 to enter (transition to) normal mode. For example, when the (terminal) disconnect button is pressed (tapped), it disconnects the connection (communication, call) between the smartphone 700 and the indoor phone base unit 100. When the (terminal) unlock button is pressed (tapped), it unlocks the electric lock 300 of the front door 31 via the indoor phone base unit 100. When the (terminal) lock button is pressed (tapped), it locks the electric lock 300 of the front door 31 via the indoor phone base unit 100.

[0031] For example, in response to a request from a smartphone 700 located within building 30 that is connected to intercom master unit 100 via communication router 400 or directly, intercom master unit 100 registers the smartphone 700. Intercom master unit 100 may also register a remote smartphone 700. Intercom master unit 100 connects to smartphone 700 as needed and exchanges various information with smartphone 700.

[0032] 2, which shows a simplified example of intercom system 10, intercom master unit 100 transfers video, audio, and various control information between front door slave unit 200 and, for example, a smartphone 700 registered with intercom master unit 100. Furthermore, intercom master unit 100 receives locking / unlocking instructions (operation of a (terminal) locking / unlocking button) from smartphone 700 and locks / unlocks electric lock 300. Therefore, intercom master unit 100 has the function of responding to a call (starting a call), displaying video of the area around the front door, locking / unlocking electric lock 300, and disabling disaster mode, all of which can be performed from smartphone 700.

[0033] As shown in FIG. 2 and as described above, the indoor phone master unit 100 receives status information indicating the activity status of the smartphone 700, the electric lock 300, the motion sensor 501, the home appliance 502, the facility equipment 503, etc.

[0034] Although FIG. 2 shows a plurality of front door slave units 200, the number of front door slave units 200 is any number equal to or greater than one.

[0035] In such an intercom system 10, if user 20's smartphone 700 is registered with intercom master unit 100, user 20 can be notified when there is a visitor at his / her home not only when he / she is inside building 30 but also when he / she is outside building 30. Furthermore, in such an intercom system 10, user 20 can talk to the visitor while checking the intercom video and can remotely unlock front door 31.

[0036] <Device configuration> Next, the configurations of the intercom master unit 100 and front door slave unit 200 included in the intercom system 10 will be described. Each of the intercom master unit 100 and front door slave unit 200 includes, for example, a central processing unit (CPU), a storage medium such as a read-only memory (ROM) that stores a control program, a working memory such as a random access memory (RAM), and a communication circuit (not shown). In this case, the functions of each functional unit (block) described below are realized by the CPU executing the control program. Alternatively, each functional unit may be realized by a dedicated device or circuit rather than a general-purpose processing device (e.g., a CPU), or may be realized by a combination of a general-purpose processing device and a dedicated device or circuit.

[0037] <Configuration of the door phone master unit> FIG. 3 is a block diagram showing an example of the configuration of indoor apparatus 100 according to the embodiment of the present disclosure.

[0038] Indoor phone master unit 100 includes video processing unit 110, display output unit 120, audio processing unit 130, audio output unit 140, audio input unit 150, call control unit 160, network control unit 170, storage unit 180, and facility equipment control unit 190. As described above, indoor phone master unit 100 may be a computer including, for example, a CPU, ROM, RAM, etc. The CPU, for example, reads a program corresponding to the processing content from ROM, loads it into RAM, and controls the operation of indoor phone master unit 100 in cooperation with the loaded program.

[0039] The video processing unit 110 processes the input video data and generates an image to be displayed by the display output unit 120. The video processing unit 110 includes a video data input unit 112 and a video data decoding unit 114.

[0040] Video data input unit 112 inputs streaming video data from front door slave unit 200. The video data may be digital or analog data. Video data input unit 112 outputs the streaming video data input from front door slave unit 200 to video data decoding unit 114.

[0041] The video data decoding unit 114 converts the streaming video data input from the video data input unit 112 into image data. The video data decoding unit 114 outputs the image data to the display output unit 120 via the call control unit 160. The images are, for example, still images. In one example, the video data is converted into still image data for 15 still images per second.

[0042] The display output unit 120 displays the image input from the video processing unit 110. The display output unit is, for example, a display such as an LCD display device or an OLED display device.

[0043] Voice processing unit 130 processes a linear electrical signal representing voice input from voice input unit 150 via call control unit 160, and outputs voice data. Voice processing unit 130 also processes voice data input from front door slave unit 200, and outputs a linear electrical signal representing voice. Voice processing unit 130 includes a voice data input unit 132, a voice data decoding unit 134, a voice data encoding unit 136, and a voice data output unit 138.

[0044] The audio data input unit 132 inputs streaming audio data from the front door slave unit 200. The audio data represents, for example, the voice of a visitor speaking to the front door slave unit 200. The audio data input unit 132 outputs the streaming audio data input from the front door slave unit 200 to the audio data decoding unit 134.

[0045] The audio data decoding unit 134 decodes the streaming audio data input from the audio data decoding unit 134, and generates a linear electrical signal representing the audio. In this embodiment, the decoding is digital-to-analog conversion. The decoding method corresponds to the encoding method used by the audio data encoding unit 236 (see FIG. 4) of the front door slave unit 200. The audio data decoding unit 134 outputs the generated linear electrical signal representing the audio to the audio output unit 140 via the call control unit 160.

[0046] The audio data encoding unit 136 encodes a linear electrical signal representing audio input from the audio input unit 150 via the call control unit 160 to generate streaming audio data. In this embodiment, the encoding is analog-to-digital conversion. The encoding method corresponds to the decoding method used by the audio data decoding unit 234 (see FIG. 4 ) of the front door slave unit 200. The audio data encoding unit 136 outputs the generated streaming audio data to the audio data output unit 138.

[0047] The audio data output unit 138 outputs the streaming audio data input from the audio data encoding unit 136 to the front door slave unit 200 .

[0048] Audio output unit 140 converts a linear electrical signal representing audio input from audio data decoding unit 134 via call control unit 160 into audio, and outputs the audio to the outside of indoor apparatus 100. In this embodiment, audio output unit 140 is a speaker.

[0049] Audio input unit 150 converts audio around indoor apparatus 100 into a linear electrical signal. In this embodiment, audio input unit 150 is a microphone.

[0050] The call control unit 160 controls calls from the front door slave unit 200. The call control unit 160 includes an incoming call processing unit 162, a timer processing unit 164, and a call processing unit 166.

[0051] The incoming call processing unit 162 processes an incoming call from the front door slave unit 200. In this embodiment, in response to notification of an incoming call from the front door slave unit 200, the incoming call processing unit 162 notifies the timer processing unit 164 of the incoming call.

[0052] Timer processing unit 164 performs timer processing from the reception of an incoming call from front door unit 200 to the start of a call between indoor apparatus 100 and front door unit 200. In this embodiment, in response to a notification of an incoming call from incoming call processing unit 162, timer processing unit 164 starts outputting a linear electrical signal representing a ring tone to audio output unit 140, and starts communication of video data between indoor apparatus 100 and front door unit 200. Also in this embodiment, in response to detecting that an answer button (not shown) provided on indoor apparatus 100 has been pressed, timer processing unit 164 stops outputting the linear electrical signal representing the ring tone to audio output unit 140 and notifies call processing unit 166 of the answer. For example, the time from the start to the end of output of the linear electrical signal representing the ring tone is three seconds.

[0053] Call processing unit 166 processes calls between indoor apparatus 100 and front door slave unit 200. In this embodiment, call processing unit 166 starts communication of audio data between indoor apparatus 100 and front door slave unit 200 in response to a response notification from timer processing unit 164. Also, in this embodiment, call processing unit 166 disconnects video and audio communication between indoor apparatus 100 and front door slave unit 200 in response to detecting the end of the call.

[0054] Network control unit 170 controls communication in accordance with a communication protocol that corresponds to the type of network through which indoor apparatus 100 communicates. Network control unit 170 includes a communication processing unit 172.

[0055] Communication processing unit 172 performs communication (transmission and reception) between indoor apparatus 100 and a communication partner of indoor apparatus 100 in accordance with a communication protocol followed by indoor apparatus 100 and the communication partner of indoor apparatus 100.

[0056] For example, the communication processing unit 172 receives status information together with the transmission date and time from the smartphone 700, the electric lock 300, the motion sensor 501, the home appliance 502, the facility appliance 503, etc. The communication processing unit 172 and / or a control unit (not shown) processes the received status information and the transmission date and time, and outputs (stores) it in the storage unit 180 in the form of a device usage log table 60 as shown in FIG.

[0057] Although not shown in FIG. 3 , when indoor apparatus 100 and a device such as smartphone 700 communicate via server 600, video, audio, and various control information are communicated via network control unit 170 (communication processing unit 172). When indoor apparatus 100 is the transmitting side, video, audio, and various control information are transmitted via call control unit 160 and network control unit 170 (communication processing unit 172) as appropriate. When indoor apparatus 100 is the receiving side, video, audio, and various control information are received via network control unit 170 (communication processing unit 172) and are stored in storage unit 180, output to display output unit 120, or output to audio output unit 140 as appropriate via call control unit 160.

[0058] The memory unit 180 stores data necessary for the operation of the door phone base unit 100, programs executed by the CPU, data received via the network control unit 170 from devices such as the smartphone 700 of the user 20, data generated by the functional units of the door phone base unit 100, usage logs of the smartphone 700, etc.

[0059] FIG. 6 is a diagram illustrating an example of a device usage log stored in the device usage log table 60 according to the embodiment of the present disclosure.

[0060] The device usage log table 60 includes a "Device" column, a "Installation Location" column, a "Last Used Date and Time" column, and a "Current Status" column.

[0061] The device names shown in the "Device" column and the installation location names shown in the "Installation Location" column are input and set in the intercom master unit 100 by the user 20, for example, directly or indirectly via the smartphone 700. Devices included in the "Device" column include the smartphone 700, the electric lock 300, the motion sensor 501, the home appliances 502 (refrigerators, etc.), the facility appliances 503 (bed sensors, toilets, gas water heaters, lighting fixtures, etc.), etc. The installation location included in the "Installation Location" column includes information about the floor on which the device is installed.

[0062] The last used date and time shown in the "Last used date and time" column and the current status shown in the "Current status" column are set by the communication processing unit 172 and / or a control unit not shown based on the status information and transmission date and time transmitted from the smartphone 700, etc.

[0063] For example, in the case of an electric lock, when status information indicating that the electric lock is locked or unlocked is transmitted from the electric lock, the transmission date and time is set as the last used date and time. Also, when the status information indicates that the electric lock is locked, the current status is set to locked, and when the status information indicates that the electric lock is unlocked, the current status is set to unlocked.

[0064] For example, in the case of a bed sensor, when status information indicating that a person is detected in bed is transmitted from the bed sensor, the transmission date and time is set as the last used date and time. If the status information indicates that a person is detected in bed, the current status is set to in use, and if the status information indicates that a person is not detected in bed, the current status is set to unused.

[0065] For example, in the case of a human presence sensor, when status information indicating that the presence of a person (or animal) has been detected is transmitted from the human presence sensor, the transmission date and time is set as the last used date and time. If the status information indicates that the presence of a person (or animal) has been detected, the current status is set to in use, and if the status information indicates that the presence of a person (or animal) has not been detected, the current status is set to unused.

[0066] For example, in the case of a refrigerator, when status information indicating that the refrigerator door has been opened or closed is transmitted from the refrigerator, the transmission date and time is set as the last used date and time. If the status information indicates that the refrigerator door has been opened, the current status is set to "door open," and if the status information indicates that the refrigerator door has been closed, the current status is set to "door closed."

[0067] For example, in the case of a toilet, when status information indicating that the toilet door has been locked or unlocked is transmitted from the toilet, the transmission date and time is set as the last used date and time. If the status information indicates that the toilet door is locked, the current status is set to in use, and if the status information indicates that the toilet door is unlocked, the current status is set to unused.

[0068] For example, in the case of a gas water heater, when status information indicating that the gas water heater has been activated or deactivated is transmitted from the gas water heater, the transmission date and time is set as the last used date and time. If the status information indicates that the gas water heater has been activated, the current status is set to in use, and if the status information indicates that the gas water heater has been deactivated, the current status is set to not in use.

[0069] For example, in the case of a lighting fixture, when the lighting fixture transmits status information indicating that the lighting fixture has been turned on or off, the transmission date and time is set as the last used date and time. If the status information indicates that the lighting fixture has been turned on, the current status is set to in use, and if the status information indicates that the lighting fixture has been turned off, the current status is set to not in use.

[0070] For example, in the case of a smartphone, when status information indicating that the smartphone is connected to intercom master unit 100 via wireless communication line 402 or that the smartphone has been disconnected from intercom master unit 100 is transmitted from the smartphone, the transmission date and time is set as the last used date and time. When the status information indicates that the smartphone is connected to intercom master unit 100 via wireless communication line 402, the current status is set to "connected to the master unit," and when the status information indicates that the smartphone has been disconnected from intercom master unit 100 via wireless communication line 402, the current status is set to "disconnected from the master unit."

[0071] The facility equipment control unit 190 communicates signals with the electric lock 300 of the entrance door 31 and controls the locking / unlocking of the electric lock 300. The facility equipment control unit 190 includes an electric lock control unit 192 and an electric lock communication unit 194.

[0072] The electric lock control unit 192 outputs a signal (lock / unlock instruction) instructing the electric lock 300 to be locked / unlocked to the electric lock communication unit 194 in response to an operation using a physical key, a press of the lock / unlock button on the indoor phone master unit 100, or a press (tap) of the (terminal) lock / unlock button on the smartphone 700. The electric lock control unit 192 also receives a signal (information) from the electric lock communication unit 194 indicating that the electric lock 300 has been locked / unlocked.

[0073] The electric lock communication unit 194 transmits the lock / unlock command input from the electric lock control unit 192 to the electric lock 300. In addition, the electric lock communication unit 194 inputs a signal (information) from the electric lock 300 indicating that the electric lock 300 has been locked / unlocked.

[0074] In addition, the above-mentioned control unit (not shown) of the indoor phone master unit 100 may control at least some of the above-mentioned functional units of the indoor phone master unit 100, and may perform functions other than the functions of these functional units.

[0075] For example, the control unit may function as an acquisition unit that acquires status information indicating the activity status of smartphones 700, electric locks 300, devices 500, etc. present in the building 30 via the communication processing unit 172, and acquires time information indicating the time related to the occurrence of a disaster.

[0076] For example, the control unit may function as a determination unit that determines whether or not a predetermined condition (for determining whether or not there is a possibility that a person is present inside the building 30) is satisfied based on the acquired status information and time information. For example, the control unit may function as an identification unit that identifies a location inside the building 30 (where there is a possibility that a person is present) based on the acquired status information and time information. For example, the control unit functioning as an identification unit may identify the installation location of the human presence sensor 501 as the location based on the acquired status information and time information that indicates the activity state of the human presence sensor 501.

[0077] For example, when a predetermined condition is satisfied, the control unit may function as a notification unit that notifies front door slave unit 200 or smartphone 700 registered in indoor apparatus 100 of information indicating that a person may be present inside building 30 via communication processing unit 172. For example, the control unit functioning as a notification unit may further notify front door slave unit 200 or smartphone 700, via communication processing unit 172, of the location (where a person may be present) in addition to the information indicating that a person may be present.

[0078] For example, when a predetermined condition is satisfied, the control unit may function as a call control unit that puts indoor apparatus 100 and front door slave unit 200 into a call state. For example, when a predetermined condition is satisfied, the control unit functioning as a notification unit may notify front door slave unit 200 of information indicating that a person may be present after a voice (for example, at a predetermined volume or higher) is input to indoor apparatus 100 via front door slave unit 200.

[0079] For example, the control unit may function as an output control unit that, when a predetermined condition is satisfied, outputs a message from (a speaker of) indoor phone master unit 100, confirming whether or not notification of information indicating that a person may be present is necessary. For example, when a predetermined condition is satisfied, the control unit functioning as a notification unit may notify front door slave unit 200 or smartphone 700 of information indicating that a person may be present if there is no response (e.g., from user 20) to the message from indoor phone master unit 100 within a predetermined time, but may not notify front door slave unit 200 or smartphone 700 of the information if there is a response from indoor phone master unit 100 within the predetermined time.

[0080] <Configuration of the entrance unit> FIG. 4 is a block diagram showing an example of the configuration of the front door slave unit 200 according to the embodiment of the present disclosure.

[0081] Doorway slave unit 200 includes video generation unit 220, audio processing unit 230, audio output unit 240, audio input unit 250, and control unit 260. As described above, doorway slave unit 200 may be a computer including, for example, a CPU, ROM, RAM, etc. The CPU, for example, reads out a program corresponding to the processing content from ROM, loads it into RAM, and controls the operation of doorway slave unit 200 in cooperation with the loaded program.

[0082] Video generation unit 220 generates video data of a subject. The subject is, for example, a visitor standing in front of front door slave unit 200. Video generation unit 220 generates video data of a subject speaking to front door slave unit 200, for example. Video generation unit 220 includes an imaging unit 222, a video data encoding unit 224, and a video data output unit 226.

[0083] The imaging unit 222 captures an image of the subject. The imaging unit 222 is, for example, a CMOS camera or a CCD camera. The imaging unit 222 outputs the captured image data of the subject to the image data encoding unit 224.

[0084] The video data encoding unit 224 encodes the video data of the subject input from the imaging unit 222 into a streaming format. In this embodiment, the encoding method may be a digital format such as MPEG-2 format, H.264 format, H.265 format, or H.266 format, or an analog format. The video data encoding unit 224 outputs the encoded video data in streaming format to the video data output unit 226.

[0085] Video data output unit 226 outputs the streaming format video data input from video data encoding unit 224 to indoor apparatus 100 (see FIG. 3).

[0086] Audio processing unit 230 processes a linear electrical signal representing audio input from audio input unit 250 and outputs audio data. Audio processing unit 230 also processes audio data input from indoor apparatus 100 and outputs a linear electrical signal representing audio. Audio processing unit 230 includes an audio data input unit 232, an audio data decoding unit 234, an audio data encoding unit 236, and an audio data output unit 238. Audio data input unit 232, audio data decoding unit 234, audio data encoding unit 236, and audio data output unit 238 have the same functions as audio data input unit 132, audio data decoding unit 134, audio data encoding unit 136, and audio data output unit 138 of indoor apparatus 100 (see FIG. 3), respectively, and therefore description thereof will be omitted.

[0087] The audio output unit 240 is a speaker that converts the linear electrical signal representing the audio input from the audio data decoding unit 234 into audio and outputs the audio to the outside of the front door slave unit 200 .

[0088] The audio input unit 250 is a microphone that converts audio around the entrance slave unit 200 into a linear electrical signal.

[0089] Control unit 260 controls the operation of video generation unit 220 and audio processing unit 230. For example, in response to pressing a call button (not shown) provided on front door slave unit 200, control unit 260 notifies master unit 100 of an incoming call, causes video generation unit 220 to start outputting video data, and causes audio processing unit 230 to start outputting audio data. Furthermore, for example, in response to detecting the end of a call, control unit 260 causes video generation unit 220 to end outputting video data and causes audio processing unit 230 to end outputting audio data. Furthermore, in response to a ringing instruction from master unit 100, control unit 260 controls front door slave unit 200 to ring to indicate that a person may be in the building or that a person may be at a certain location.

[0090] <Door phone system operation> Next, an example of the operation of the door phone system 10 according to the embodiment of the present disclosure will be described.

[0091] FIG. 5 is a flowchart illustrating an example of the operation of indoor phone master unit 100 according to an embodiment of the present disclosure. In this example, it is assumed that indoor phone master unit 100 knows the current time. For example, it is assumed that indoor phone master unit 100 can obtain time information from an NTP (Network Time Protocol) server via a network. In addition, in the scenario illustrated in FIG. 6, which will be referred to below, it is assumed that user 20 returns home at 10:30 PM on June 1, 2022, wakes up at 6 AM on June 2 the following day, eats breakfast, and is relaxing in the living room when indoor phone master unit 100 receives an emergency earthquake alert at 9 AM.

[0092] In step S501, the intercom master unit 100 (communication processing unit 172, control unit (acquisition unit)) waits for disaster information regarding the occurrence of earthquakes, tsunamis, floods, etc. and evacuation instructions from a disaster information provider, for example, that has been pre-registered in the intercom master unit 100.

[0093] In step S502, indoor apparatus 100 (communication processing unit 172, control unit (acquisition unit)) determines whether disaster information has been received.

[0094] If indoor apparatus 100 has not received disaster information (step S502: NO), the flow returns to step S501.

[0095] On the other hand, if the door phone master unit 100 receives disaster information (step S502: YES), in step S503, the door phone master unit 100 (control unit (determination unit)) checks the status of various devices by checking the device usage log table 60 shown in Figure 6 stored in the memory unit 180 based on the reception time of the disaster information received in step S502.

[0096] In step S504, indoor apparatus 100 (control unit (determination unit)) determines whether or not there is a possibility that someone is present at home, based on the device status confirmed in step S503.

[0097] If it is determined that there is no possibility that a person is at home (step S504: NO), the flow ends.

[0098] On the other hand, if it is determined that there is a possibility that someone is at home (step S504: YES), in step S505, intercom master unit 100 (controller (output control unit)) causes the speaker of intercom master unit 100 to output a confirmation message requesting confirmation as to whether it is OK to output a message indicating that there is a possibility that someone is at home from the speaker of front door slave unit 200. At this time, if it is unnecessary to output a message indicating that there is a possibility that someone is at home from the speaker of front door slave unit 200, intercom master unit 100 (controller (output control unit)) also causes the speaker of intercom master unit 100 to output a message guiding the user to press a predetermined button within a predetermined time (for example, 20 seconds). This makes it possible to avoid outputting unnecessary messages (ringing) when there is someone in building 30 but no rescue is required.

[0099] In step S506, indoor apparatus 100 (controller) determines whether a predetermined button has been pressed (whether a response has been made to the confirmation message) within a predetermined time (for example, 20 seconds) since the confirmation message was output.

[0100] If it is determined that the predetermined button has been pressed within the predetermined time (step S506: YES), the flow ends.

[0101] On the other hand, if it is determined that the predetermined button has not been pressed within the predetermined time (step S506: NO), master unit 100 (controller) enters (transitions to) disaster mode in step S507.

[0102] In step S508, indoor apparatus 100 (control unit (identification unit)) identifies a location where a person may be present, based on the device status confirmed in step S503.

[0103] In step S509, intercom master unit 100 (control unit (communication control unit)) puts intercom master unit 100 and front door slave unit 200 into a communication state, and starts a two-way communication with front door slave unit 200. As a result, audio from inside building 30 is output from front door slave unit 200, and external audio around front door slave unit 200 is output from intercom master unit 100 into building 30, thereby further increasing the possibility of rescue.

[0104] In step S510, indoor apparatus 100 (control unit (notification unit)) displays an emergency status indicating that a person may be present at home (or may have collapsed), and instructs front door slave unit 200 to ring the location identified in step S508 (sends a ring instruction to front door slave unit 200). This ring instruction is an example of "information indicating that a person may be present in the house" according to the present disclosure. This reduces the time required to search for the person to be rescued, thereby increasing the likelihood of rescue.

[0105] In step S511, indoor apparatus 100 (communication processing unit 172, control unit) waits for an instruction to cancel disaster mode.

[0106] In step S512, indoor apparatus 100 (communication processing unit 172, control unit) determines whether or not a disaster mode release instruction has been received.

[0107] If indoor apparatus 100 has not received the instruction to cancel the disaster mode (step S512: NO), the flow returns to step S511.

[0108] On the other hand, if indoor apparatus 100 receives the instruction to cancel disaster mode (step S512: YES), indoor apparatus 100 (controller) enters (transitions to) the normal mode, and the flow ends.

[0109] Some steps shown in FIG. 5 will now be described in more detail.

[0110] In step S503 of FIG. 5, for example, indoor phone master unit 100 (control unit (determination unit)) checks the device usage log going back a predetermined time (for example, two hours) from the time the disaster information was received to check the current status of the devices. Therefore, in this case, in device usage log table 60, records corresponding to human presence sensor 1, human presence sensor 2, toilet, gas water heater, lighting fixture 1, and smartphone in the "Devices" column are checked. Note that the predetermined time may be input and set by user 20 into indoor phone master unit 100.

[0111] In step S504 of FIG. 5 , for example, if there is a device (e.g., a motion sensor) that indicates the possibility that a person is in building 30, such as a device with a value of "in use" or similar stored in the "current status" column of device usage log table 60 shown in FIG. 6 , intercom master unit 100 (controller (determination unit)) may determine that there is a possibility that a person is in building 30; otherwise, it may determine that there is no possibility that a person is in building 30. Alternatively, intercom master unit 100 (controller (determination unit)) may determine whether there is a possibility that a person is in building 30 based on a predetermined rule. For example, if there is a history of toilet use and the front door has not been opened or closed during a predetermined time (e.g., two hours) before receiving disaster information, intercom master unit 100 (controller (determination unit)) may determine that there is a possibility that a person is in building 30. Furthermore, for example, if there is a history of lighting device use and the front door has been opened and closed during a predetermined time (e.g., two hours) before receiving disaster information, intercom master unit 100 (controller (determination unit)) may determine that there is no possibility that a person is in building 30. Furthermore, for example, if smartphone 700 of user 20 is currently connected to indoor apparatus 100 via wireless communication line 402, indoor apparatus 100 (control unit (determination unit)) may determine that there is a possibility that someone is at home. By setting such a rule, it is possible to reduce the possibility of a missed detection, where it is determined that there is no possibility that someone is at home.

[0112] Examples of "predetermined conditions" according to the present disclosure include "the human presence sensor is currently in use," "the toilet has been used and the front door has not been opened or closed within a predetermined period of time (e.g., two hours) prior to receiving the disaster information," and "the smartphone 700 is currently connected to the door phone base unit 100 via the wireless communication line 402."

[0113] In step S508 of FIG. 5, for example, if there is a motion sensor that is in use, intercom master unit 100 (controller (identifier)) may first identify the installation location of the motion sensor as a location where a person may be present. For example, in the example shown in FIG. 6, because motion sensor 2 is currently in use, intercom master unit 100 (controller (identifier)) may identify (detect) that a person may be in the living room on the first floor (for example, that a person may have collapsed in the living room on the first floor). If there is no motion sensor that is in use, for example, intercom master unit 100 (controller (identifier)) may then identify, as a location where a person may be present, the installation location of a device whose last use date and time in device usage log table 60 is closest to the date and time when the disaster information was received.

[0114] 5, for example, intercom master unit 100 (control unit (output control unit)) may control intercom master unit 100 to increase the sensitivity of the microphone of intercom master unit 100 (for example, to the maximum) and increase the audio output from the speaker of intercom master unit 100 (for example, to the maximum). Also, for example, in step S509 of FIG. 5, intercom master unit 100 (control unit (output control unit)) may instruct front door slave unit 200 to increase the sensitivity of the microphone of front door slave unit 200 (for example, to the maximum) and increase the audio output from the speaker of front door slave unit 200 (for example, to the maximum) (such an instruction may be transmitted to front door slave unit 200).

[0115] The indication of the emergency state in step S510 of FIG. 5 may be, for example, by flashing an LED provided in front door slave unit 200 in red. Also, in step S510 of FIG. 5, for example, in the example shown in FIG. 6, indoor apparatus 100 (control unit (notification unit)) may instruct front door slave unit 200 to sound a message such as "There may be a person in the living room on the first floor" or "There may be a person collapsed in the living room on the first floor." If no motion sensor is in use in step S508, indoor apparatus 100 (control unit (identification unit)) may not need to identify the location. Furthermore, indoor apparatus 100 may not execute step S508 itself. If the location is not identified in this way, indoor apparatus 100 (control unit (notification unit)) may instruct front door slave unit 200 in step S510 to simply sound a message indicating that there may be a person in the house, instead of a location. This instruction is also an example of "information indicating that there may be a person in the house" according to the present disclosure. In addition to or instead of issuing an instruction to front door slave unit 200, intercom master unit 100 (control unit (notification unit)) may notify smartphone 700 registered with intercom master unit 100 (e.g., a smartphone of a family member or relative of user 20) of information indicating that there may be someone inside the house. In step S510 of FIG. 5, for example, initially, intercom master unit 100 may only issue an instruction to display an emergency state, and after audio (e.g., audio at or above a predetermined volume) from around front door slave unit 200 is input to intercom master unit 100, intercom master unit 100 (control unit (notification unit)) may instruct front door slave unit 200 to sound a message. This can prevent the message from being sounded excessively.

[0116] The instruction to cancel disaster mode in steps S511 and S512 of Figure 5 may be made, for example, in response to pressing a disaster mode cancel button provided on the door phone base unit 100, or in response to pressing (tapping) a (terminal) disaster mode cancel button on the smartphone 700 registered to the door phone base unit 100.

[0117] <Modification of the embodiment> In the above, a residential house was used as an example of where the door phone base unit 100 is installed to determine whether or not there is a possibility that someone is at home, but the door phone base unit 100 may also be installed in general buildings such as stores, factories, warehouses, and other buildings, and may determine whether or not there is a possibility that someone is at home.

[0118] The order of the steps in Fig. 5 is not limited to the order shown in the figure. For example, the order of steps S507, S508, and S509 can be arbitrarily changed.

[0119] 5 may be read as "the time or date when the disaster information was received" or "the time or date when a disaster warning was issued" or "the time or date when a disaster occurred." The "time or date and time when the disaster information was received," "the time or date and time when a disaster warning was issued," and "the time or date and time when a disaster occurred" are examples of "time information indicating the time related to the occurrence of a disaster" according to the present disclosure.

[0120] 5 includes an earthquake early warning, a heavy rain and flood warning, etc., and the example has been described in which the reception of these disaster information triggers the determination of whether or not there is a possibility that a person is at home. In addition, a sensor that detects the collapse of building 30, the flooding of building 30, etc. may be installed in building 30, and the determination of whether or not there is a possibility that a person is at home may be triggered by the reception by intercom master unit 100 of sensor information indicating the detection by such a sensor. Therefore, the time or date when such sensor information is received is also an example of "time information indicating the time related to the occurrence of a disaster" according to the present disclosure.

[0121] In the above, an example has been described in which intercom master unit 100 performs operations according to the present disclosure using data such as a device usage log. However, data such as a device usage log may be stored in a cloud (e.g., a server), and at least some of the operations described as being performed by intercom master unit 100 may be performed in the cloud. For example, at least some of the functions of intercom master unit 100 (functional units shown in FIG. 3 ) may be provided in server 600 or another server. In this case, intercom master unit 100 does not need to perform processing corresponding to the function, but simply transfers various data to server 600 or another server, and server 600 or another server performs the processing corresponding to the function. This reduces the cost of intercom master unit 100 and the processing load on intercom master unit 100.

[0122] The above-described functional units may be divided into further functional units, or two or more functional units may be integrated into one functional unit. For example, the determination unit and the identification unit may exist as the same functional unit.

[0123] Intercom master unit 100 may be realized as a single device having all of the above-mentioned functional units, or as multiple devices in which the above-mentioned functional units are distributed. When intercom master unit 100 is realized as multiple devices, the functions of intercom master unit 100 can be realized by cooperation via a network using communication units provided in the multiple devices.

[0124] <Effects of the embodiment> As described above, according to the present embodiment, intercom master unit 100 (control unit (acquisition unit)) acquires status information indicating the activity status of devices (smartphone 700, electric lock 300, device 500, etc.) present in home building 30 of user 20, and acquires time information related to the occurrence of a disaster. Intercom master unit 100 (control unit (determination unit)) determines whether a predetermined condition (for determining whether there is a possibility that a person is in home building 30) is met based on the acquired status information and time information. Then, if the predetermined condition is met (if there is a possibility that a person is in home building 30), intercom master unit 100 (control unit (notification unit)) notifies front door slave unit 200 or a wireless mobile terminal (smartphone 700) registered in intercom master unit 100 of information indicating that there is a possibility that a person is in home building 30.

[0125] Therefore, according to this embodiment, it is determined whether or not a specified condition is met, and if the specified condition is met, information indicating that there may be a person inside the building 30 is notified to the door phone sub-unit or wireless mobile terminal, thereby increasing the possibility of rescue in the event of a disaster.

[0126] <Summary of the embodiment> A door phone master unit (door phone master unit 100) according to one embodiment of the present disclosure includes an acquisition unit (CPU, control unit) that acquires status information indicating the activity status of devices (smartphone 700, electric lock 300, device 500, etc.) present in a house (building 30) and acquires time information indicating the time related to the occurrence of a disaster, a determination unit (CPU, control unit) that determines whether or not a specified condition is met based on the status information and the time information, and a notification unit that, if the specified condition is met, notifies a door phone slave unit (front door slave unit 200) or a wireless mobile terminal (smartphone 700) registered to the unit of information indicating that there may be someone inside the house.

[0127] With the above configuration, when certain conditions are met, information indicating that there may be someone inside the house is sent to the door phone slave or wireless mobile terminal, thereby increasing the possibility of rescue in the event of a disaster.

[0128] The door phone master unit further includes an identification unit (CPU, control unit) that identifies a location within the house based on the status information and the time information, and the notification unit further notifies the door phone slave unit or the wireless mobile terminal of the location.

[0129] With the above configuration, a location where a person (person to be rescued) may be present can be identified, thereby reducing the time required to search for the person to be rescued and increasing the possibility of rescue.

[0130] The indoor apparatus further includes a call control unit (CPU, control unit) that puts the indoor apparatus and the indoor apparatus into a call state when the predetermined condition is satisfied.

[0131] With the above configuration, audio from inside the house is output from the intercom slave unit, and audio from outside the area around the intercom slave unit is output from the intercom master unit into the house, thereby further increasing the possibility of rescue.

[0132] In this intercom master unit, when the specified condition is met, after voice is input to the intercom master unit via the intercom slave unit, the notification unit notifies the intercom slave unit of the information.

[0133] With the above configuration, it is possible to prevent information (for example, messages) from being excessively notified (for example, sounded).

[0134] The door phone master unit further includes an output control unit (CPU, control unit) that causes the door phone master unit to output a message when the specified conditions are met, and the notification unit notifies the door phone slave unit or the wireless mobile terminal of the information when the specified conditions are met and there is no response to the message from the door phone master unit within a specified time.

[0135] With the above configuration, when there is a response to the message (for example, when there is someone in the building but no rescue is required), it is possible to avoid notification (for example, ringing) of unnecessary information (for example, a message).

[0136] In a notification method according to one embodiment of the present disclosure, a door phone master unit (door phone master unit 100) acquires status information indicating the activity status of devices (smartphone 700, electric lock 300, device 500, etc.) present in a house (building 30), acquires time information indicating the time related to the occurrence of a disaster, determines whether or not a specified condition is met based on the status information and the time information, and if the specified condition is met, notifies a door phone slave unit (front door slave unit 200) or a wireless mobile terminal (smartphone 700) registered to the door phone master unit of information indicating that there may be someone inside the house.

[0137] With the above configuration, when certain conditions are met, information indicating that there may be someone inside the house is sent to the door phone slave or wireless mobile terminal, thereby increasing the possibility of rescue in the event of a disaster.

[0138] In the above-described embodiments, the notation "... part" used for each component may be replaced with other notations such as "... circuitry," "... assembly," "... device," "... unit," or "... module."

[0139] Although the embodiments have been described above with reference to the drawings, the present disclosure is not limited to such examples. It is clear that a person skilled in the art can conceive of various modifications or alterations within the scope of the claims. It is understood that such modifications or alterations also fall within the technical scope of the present disclosure.
