  FIG. 2 is a diagram for explaining a configuration example of the distribution board 6 common to the embodiments. The distribution board 6 branches the main circuit connected to the commercial power supply 8 into a plurality of branch circuits. The distribution board 6 includes a main circuit breaker 11 provided in the main circuit, a branch circuit breaker 12 provided in each branch circuit, a power measuring device 13, a control unit 15, a communication unit 16, and a seismic sensor 17.

The main breaker 11 is provided between the branch point between the main circuit and the branch circuit and the commercial power supply 8. The branch breaker 12 is provided between a branch point between the main circuit and the branch circuit and an outlet to which the electric device 9A is connected.

The electric device 9A is various electric loads such as an air conditioner, a refrigerator, a washing machine, a TV, a vacuum cleaner, lighting, a water heater, a speaker, a microwave oven, an electromagnetic cooker, and a charger for an electric vehicle.

  The power measuring device 13 measures a current value flowing through a circuit to be measured (target circuit) in a predetermined period, for example, a predetermined number of cycles, and acquires measured current information. In other words, the power measurement device 13 acquires the measurement current waveform (measurement current waveform that can be generated from the measurement current information) of the target circuit. Hereinafter, the measurement current waveform may be read as measurement current information. The power measuring device 13 has a function of communicating with the outside via a communication function (not shown).

  The seismic sensor 17 detects shaking and supplies a seismic detection signal to the control unit 15 by the communication function of the power measuring device 13 or the communication unit 16 based on the detection of the shaking. For example, the seismic sensor 17a of 1st Embodiment mentioned later is comprised by an acceleration sensor, for example. The seismic sensor 17 a detects acceleration due to shaking and supplies a seismic detection signal corresponding to the detected acceleration to the control unit 15. For example, when a first acceleration (corresponding to a seismic intensity of 4 or more (less than seismic intensity 5) is detected), a first seismic detection signal is output and a second acceleration (corresponding to a seismic intensity of 5 or more) is detected. Then, the second seismic detection signal is output. Or the seismic sensor 17 may transmit the corresponding detection signal according to linear or arbitrary functions according to the magnitude | size of the detected acceleration. Or the seismic sensor 17b of 2nd Embodiment mentioned later detects the shake more than fixed value (for example, shake more than seismic intensity 5), and the control part 15 shows the seismic detection signal which shows the detection of the shake more than fixed value. To supply.

  In the first embodiment to be described later, the control unit 15 controls the main circuit breaker 11 to shut off the main circuit in response to the reception of the second seismic detection signal from the seismic sensor 17a. Or the control part 15 interrupts | blocks a main circuit with the main breaker 11 corresponding to reception of the 2nd seismic detection signal from the seismic sensor 17a. In the second embodiment, which will be described later, the control unit 15 receives a seismic detection signal from the seismic sensor 17b for a first time (for example, 30 seconds) or longer or a seismic detection signal. After the second time (for example, 3 minutes) elapses, the main circuit is controlled by the main circuit breaker 11. The control unit 15 may prevent the main circuit breaker 11 from shutting off the main circuit (supplied power) when the communication unit 16 receives the abnormality occurrence information from the home gateway device 7 or a cutoff command based on the abnormality occurrence information. Good. As for the interruption of the main circuit, for example, a means for immediately interrupting the main circuit by inputting a pseudo-leakage into the main circuit can be considered.

  The electric device 9A connected to the branch circuit of the distribution board 6 is an electric device compatible with HEMS. The electrical device 9A can communicate with the home gateway device 7. For example, the electric device 9 </ b> A can transmit device information including its own device identification information and an operation state indicating its own operation state to the home gateway device 7.

  The device identification information is information that can identify the type of the electrical device 9A. The device identification information is, for example, a model number assigned to each product type, a combination of a model number and a MAC address, or a combination of a model number and an arbitrary character string.

  The operating state is information indicating the operating state of the electrical device 9A expressed by a telegram system defined in ECHONET Lite, for example. For example, the operating state may be a power state indicating whether the power of the electric device 9A is ON or OFF, or various operating states such as the power saving operation state or the standby state of the electric device 9A. Good. More specifically, when the electrical apparatus 9A is an air conditioner, the operation state may indicate various states such as cooling, heating, air blowing, dehumidification, set temperature, and air volume.

  Next, the configuration of the home gateway device 7 will be described.

FIG. 3 is a block diagram for explaining a configuration example of the home gateway device 7 common to the embodiments.
The home gateway device 7 monitors the power consumption of each electrical device 9A in the home network system 2 and controls each electrical device 9A. 3, the home gateway device 7 includes a communication unit 21, a storage unit 22, and a control unit 23 (first control unit).

  The communication unit 21 communicates with the server 3 via the outside network 5. In addition, the communication unit 21 communicates with the distribution board 6, the user terminal 4, and each electrical device 9 </ b> A in the home network system 2. The communication unit 21 includes a wireless communication unit 24 and a wired communication unit 25. The wireless communication unit 24 and the wired communication unit 25 have different communication means, but have the same function in the present invention, and may be interchanged in the following description.

  The wireless communication unit 24 is connected to each device that performs wireless communication with the home gateway device 7. For example, the wireless communication unit 24 performs wireless communication with the distribution board 6, the user terminal 4, each electrical device 9 </ b> A, and the like. The wireless communication unit 24 includes a transceiver that transmits and receives radio waves, infrared rays, and the like.

  The wired communication unit 25 is connected to each device that performs wired communication with the home gateway device 7. For example, the wired communication unit 25 connects the home gateway device 7 to be communicable with the external network 5 via a relay device such as a router (not shown). The wired communication unit 25 includes a connection port into which a LAN cable is inserted, a communication circuit, and the like.

  The storage unit 22 stores various information. The storage unit 22 is configured by a storage device such as a semiconductor memory or a hard disk drive, for example.

The control unit 23 includes a processor such as a CPU, a program memory, a working memory, and various interfaces. The control unit 23 implements various processing functions by executing a program stored in the program memory by the processor.
For example, the control unit 23 processes information transmitted to and received from the power measurement device 13 in the distribution board 6, the communication unit 16, the user terminal 4, and each electrical device 9A. In addition, the control unit 23 processes information transmitted to and received from the server 3.

  The control unit 23 recognizes the device identification information and the operation state of the electric device 9A from the device information transmitted from the electric device 9A. In addition, the control unit 23 calculates the power consumption of each electrical device 9A in the home network system 2 based on the measurement information transmitted from the power measurement device 13 of the distribution board 6. The control unit 23 generates a device list by associating the device identification information with the operation state, the installation location, the power consumption, and the like, and stores the device list in the storage unit 22. Further, the control unit 23 updates the device list based on the device information and the calculated power consumption.

  The device list includes device identification information, operation status, installation location, and power consumption. The installation location is information that can identify the branch circuit to which the electrical device 9A is connected among the plurality of branch circuits branched by the distribution board 6, for example. In addition, for example, the installation location is information indicating a location where the electrical device 9A such as a living room or an entrance is installed. The control unit 23 acquires information input by the user from the user terminal 4 from the user terminal, and sets an installation location based on the acquired information. The power consumption is the power consumption of the electric device 9A calculated by the control unit 23 as described above. The device lists shown in FIGS. 9, 10, and 11 include device names, connection states, and control information in addition to the device list information described here.

  The control unit 23 can cause the user terminal 4 to generate a power consumption confirmation screen and a control screen by transmitting the device list to the user terminal 4. Moreover, the control part 23 may be the structure which produces | generates a power consumption confirmation screen and a control screen, and transmits to a user terminal. Furthermore, the control unit 23 may be configured to transmit the device list to the server 3 at a predetermined timing (for example, periodic timing or arbitrary timing).

Next, the configuration of the server will be described.
The server 3 manages various types of information related to the electrical device 9A corresponding to HEMS. For example, when the server 3 receives a control signal from the user terminal 4 via the network 5, the server 3 transmits the received control signal to the home gateway device 7 via the network 5. Thereby, the electric equipment 9A in the home network system 2 can be controlled. Further, the server 3 can acquire a device list from the home gateway device 7 via the network 5 and transmit it to the user terminal 4. Thereby, the server 3 can make the user terminal 4 generate a power consumption confirmation screen and a control screen. The server 3 may be configured to generate a power consumption confirmation screen and a control screen using the device list acquired from the home gateway device 7 and transmit the screen to the user terminal.

FIG. 4 is a block diagram for explaining a configuration example of the server 3 common to the embodiments. In the configuration example illustrated in FIG. 4, the server 3 includes a communication unit 31, a storage unit 32, and a control unit 33.
The communication unit 31 communicates with the home gateway device 7 and the user terminal 4 via the network 5.

The storage unit 32 stores various information. The storage unit 32 is configured by a storage device such as a semiconductor memory or a hard disk drive, for example. The storage unit 32 stores registration information for each electrical device 9A. The registration information is information in which the device identification information is associated with the operation state of the electric device 9A. The control unit 33 includes a processor such as a CPU, a program memory, a working memory, and various interfaces. The control unit implements various processing functions by executing a program stored in the program memory by the processor.
In the first and second embodiments described below, an example of emergency earthquake warning (earthquake information) will be described as abnormality occurrence information, but the present invention is not limited to this. For example, fire occurrence information may be used as the abnormality occurrence information.
(First embodiment)
First, the first embodiment will be described.
FIG. 5 is a flowchart illustrating an example of operation control according to the first embodiment.
As illustrated in FIG. 5, the wireless communication unit 24 of the home gateway device 7 collects (receives) device information (step S501). For example, at the time of initial setting and periodically, the wireless communication unit 24 requests device information from each device (electric device 9A) in the facility and receives device information from each device. The storage unit 22 of the home gateway device 7 stores the received device information (step S502). In addition, the device information stored in the storage unit 22 may be periodically updated, or may be updated at a timing such as when the electric device 9A newly enters the home network system 2.

  The control unit 23 of the home gateway device 7 generates a device list based on the received device information. For example, the wired communication unit 25 of the home gateway device 7 receives the control information of each device from the server at the time of initial setting, when there is an instruction from the user, or periodically, and the control unit 23 receives the received device. A device list can be generated based on the information and the control information. Further, the generated device list is periodically updated based on control information that is periodically received. The user may be able to edit based on the control information received from the server, or may be set freely by the user.

  FIG. 9 is a diagram illustrating an example of a first device list that can be used in the operation control according to the first embodiment. As shown in FIG. 9, for example, the first device list includes device identification information, device name, connection state, and control information, and the control information is activated by an emergency earthquake warning (earthquake information) as abnormality occurrence information. Or stop (guidance mode) and stop by a seismic detection signal (device protection mode) are included. The control unit 23 controls the operation of each device in the facility based on various received signals and the first device list.

  Note that the server 3 may generate a device list. For example, the wireless communication unit 24 of the home gateway device 7 transmits device information at the time of initial setting and periodically. The server 3 stores the control information of each device, receives the device information transmitted from the home gateway device 7, and generates a device list based on the received device information and the stored control information. Can do. The server 3 transmits the generated device list to the home gateway device 7. Thereby, the home gateway device 7 can receive the device list from the server 3. Further, the server 3 may periodically update the device list and transmit the updated device list to the home gateway device 7 or may transmit it according to a user instruction.

  When the Japan Meteorological Agency detects the occurrence of an earthquake, it sends an emergency earthquake bulletin. The server 3 receives this earthquake early warning and notifies the home gateway device 7 of it. When the wired communication unit 25 of the home gateway device 7 receives the earthquake early warning (step S503, YES), the control unit 23 responds to the reception of the earthquake early warning by the wireless communication unit 24 by the first device list. Operation control information (for example, a power-on signal / power-off signal) is transmitted to each device registered in (1). That is, the wireless communication unit 24 transmits the operation control information to each device registered in the first device list (step S504). Here, the server 3 that transmits the abnormality occurrence information and the server 3 that transmits the device list may be integrated or separate. When the server 3 stores the device list, necessary control information may be directly transmitted from the server 3 to the home gateway device 7 when the abnormality occurrence information is received.

  In accordance with the control information of the first device list shown in FIG. 9, for example, operation control information (start / stop) is transmitted to each device of the device identification information 0011, 0012, 0013, 0031, 0041, 0051, and 0061. . As a result, each device operates (starts / stops). For example, by transmitting the operation control information (activation) to each device of the device identification information 0011, 0012, 0013, 0031, 0041, the illumination of the device identification information 0011, 0012, 0013 is turned on, and the TV of the device identification information 0031 is turned on. The program being started and being broadcast is output (for example, the earthquake early warning is displayed or output as audio), the speaker of the device identification information 0041 is also started and the program being broadcast is output (for example, the earthquake early warning is output as audio) ). According to the control information in the first device list, for example, the operation control information is not transmitted to the device with the device identification information 0021, and the operation control information (stop) is transmitted to each device with the device identification information 0051 and 0061. The Thereby, the microwave oven and electromagnetic cooker which are starting are stopped. The reason for stopping these devices is to prevent fire.

  For example, the home gateway device 7 can execute the guidance mode by transmitting operation control information corresponding to the reception of the earthquake early warning. By executing the guidance mode, for example, the lighting is turned on and an emergency earthquake warning is notified. This makes it easier to notice emergency earthquake alerts even at midnight hours. In addition, since the lighting is turned on, evacuation can be facilitated even in the midnight hours.

  Moreover, if the seismic sensor 17a of the distribution board 6 detects a shake, it outputs (transmits) a seismic detection signal corresponding to the detected shake (seismic intensity). For example, if a seismic intensity of 4 or more (less than seismic intensity 5) is detected, a first seismic detection signal is output, and if a seismic intensity of 5 or more is detected, a second seismic detection signal is output.

  When the wireless communication unit 24 of the home gateway device 7 receives the first seismic detection signal from the seismic sensor 17a (step S505, YES), the control unit 23 of the home gateway device 7 performs the first seismic detection. In response to the reception of the signal, the wireless communication unit 24 transmits operation control information (for example, a power-off signal) to each device registered in the first device list. That is, the wireless communication unit 24 transmits the operation control information (stop) to each device registered in the first device list (step S506).

  In accordance with the control information in the first device list shown in FIG. 9, for example, operation control information (stop) is transmitted to each device of the device identification information 0021, 0031, 0041, 0051, and 0061. As a result, the operating devices that are easily damaged by a sudden shut-off stop the operation, and the stopped devices continue to be stopped. In order to secure an evacuation route until the main circuit, which will be described later, is shut down, for example, the operation control information (stop) is not transmitted to each device of the device identification information 0011, 0012, 0013.

  For example, the home gateway device 7 can execute the device protection mode by transmitting the operation control information (stop) corresponding to the reception of the first seismic detection signal. By executing the device protection mode, the operation of each device (including the operation of each device in the guidance mode) can be stopped. As a result, each device can be protected (the device can be prevented from being damaged due to a sudden power failure), and the risk of an electric fire (an electric fire caused by each device operating in the induction mode) can be reduced. it can.

  Further, when the seismic sensor 17a outputs the second seismic detection signal, the distribution board control unit 15 responds to the reception of the second seismic detection signal (step S507, YES), and the main circuit. Is blocked (step S508). That is, the distribution board 6 executes the main cutoff mode in response to the reception of the second seismic detection signal described above, and stops the power supply to each device. Thereby, an electric fire can be prevented.

  FIG. 6 is a diagram illustrating an example of execution conditions in each mode by operation control according to the first embodiment. In the operation control according to the first embodiment, as shown in FIG. 6, the home gateway device 7 executes the guidance mode in response to the reception of the earthquake early warning and receives the first seismic detection signal. The device protection mode is executed in response to (detection from a weak earthquake with a seismic intensity of less than 5 to a slightly strong earthquake). Furthermore, the distribution board 6 executes the master cutoff mode in response to reception of the second seismic detection signal (detection of a strong earthquake having a seismic intensity of 5 or more). Each mode can be executed independently. For example, even if the earthquake early warning is not transmitted (even if the home gateway device 7 does not receive the earthquake early warning), if the home gateway device 7 receives the first earthquake detection signal, the device protection mode is set. If the distribution board 6 receives the second seismic detection signal, the main cut-off mode is executed.

As described above, when the earthquake early warning is received, the guidance mode is executed, and the emergency earthquake early warning is transmitted more reliably and evacuation is facilitated. When a slightly strong earthquake is detected from a weak earthquake with a seismic intensity of less than 5, the device protection mode is executed, and the operation of the device registered in the first device list and effective in stop control is stopped. Thereby, the operation | movement of the intended apparatus can be stopped and operation | movement of apparatuses other than these can not be stopped. For example, a medical device or the like can be excluded from the target of stop control. Further, in the case of a strong earthquake with a seismic intensity of 5 or more, it is possible to cut off the power supply to all devices by emphasizing the execution of the main cut-off mode and preventing an electric fire or the like.
(Second Embodiment)
Next, a second embodiment will be described.

  FIG. 7 is a flowchart illustrating an example of operation control according to the second embodiment. As shown in FIG. 7, the wireless communication unit 24 of the home gateway device 7 collects (receives) device information (step S701), and the storage unit 22 stores the received device information (step S702). When the wired communication unit 25 of the home gateway device 7 receives the earthquake early warning (step S703, YES), the wireless communication unit 24 transmits operation control information to each device registered in the first device list. (Step S704). Steps S701 to 704 described above correspond to steps S501 to 504 described in the first embodiment.

  For example, it is assumed that the seismic sensor 17b of the distribution board 6 is a sensor that outputs (transmits) a seismic detection signal when a certain level of vibration is detected. In the first embodiment, the case of applying the seismic sensor 17a that outputs a seismic detection signal corresponding to the detected shaking (seismic intensity) has been described. However, in the second embodiment, a relatively low price that exceeds a certain level is described. A case will be described in which a seismic sensor 17b that outputs (transmits) a seismic detection signal when shaking is detected is described.

  For example, if a seismic intensity of 4 or 5 or more is detected, the seismic sensor 17b outputs a seismic detection signal. The wireless communication unit 24 of the home gateway device 7 receives the seismic detection signal, and the distribution board control unit 15 also receives the seismic detection signal.

  When the wireless communication unit 24 of the home gateway device 7 receives the seismic detection signal from the seismic sensor 17b (step S705, YES), the control unit 23 of the home gateway device 7 receives the first seismic detection signal. In response to this, the wireless communication unit 24 transmits operation control information (for example, a power-off signal) to each device registered in the first device list. That is, the wireless communication unit 24 transmits operation control information (stop) to each device registered in the first device list (step S706).

  In accordance with the control information in the first device list shown in FIG. 9, for example, operation control information (stop) is transmitted to each device of the device identification information 0021, 0031, 0041, 0051, and 0061. As a result, the operating devices that are easily damaged by a sudden shut-off stop the operation, and the stopped devices continue to be stopped.

  For example, the home gateway device 7 can execute the device protection mode by transmitting operation control information (stop) corresponding to the reception of the above-described seismic detection signal. By executing the device protection mode, the operation of each device (including the operation of each device in the guidance mode) can be stopped. As a result, each device can be protected (the device can be prevented from being damaged due to a sudden power failure), and the risk of an electric fire (an electric fire caused by each device operating in the induction mode) can be reduced. it can.

  Further, after the first time (for example, 3 minutes) has elapsed since the control unit 15 of the distribution board 6 receives the seismic detection signal (step S707, YES), the main circuit is interrupted by the main circuit breaker 11 (step S707). S708). As a result, it is possible to cut off the power supply after executing the device protection mode in an emergency and prevent an electric fire. In addition, the control part 15 may have a function which stores a seismic detection signal at the time of a power failure, and interrupts | blocks a main trunk at the time of power recovery. Thereby, the secondary fire at the time of power recovery can be prevented. When the control unit 15 continuously receives the seismic detection signal for a second time (for example, 30 seconds) or more (step S707, YES), the main circuit may be shut off (step S708). That is, if the distribution board 6 continues to receive the seismic detection signal for a certain time or longer, the distribution board 6 executes the main cutoff mode and stops the power supply to each device. Thereby, when a big earthquake occurs, the supply of electric power can be cut off without waiting for the first time described above, and the electric devices not corresponding to the electric devices 9A and HEMS can be stopped to prevent an electric fire. .

  FIG. 8 is a diagram illustrating an example of execution conditions in each mode by operation control according to the second embodiment. In the operation control according to the second embodiment, as shown in FIG. 8, the home gateway device 7 executes the guidance mode in response to the reception of the earthquake early warning, and receives the seismic detection signal (seismic intensity 4 Or the device protection mode is executed in response to the detection of five or more earthquakes. Furthermore, the distribution board 6 executes the master cutoff mode after the second time has elapsed since the seismic detection signal was continuously received for the first time or longer or the seismic detection signal was received. Each mode can be executed independently. For example, even if the earthquake early warning is not transmitted (even if the home gateway device 7 does not receive the earthquake early warning), if the home gateway device 7 receives the seismic detection signal, the device protection mode is executed. After the distribution board 6 receives the seismic detection signal continuously for a first time (for example, 30 seconds) or after receiving the seismic detection signal, the main blocker mode is set. Run.

  As described above, when the earthquake early warning is received, the guidance mode is executed, and the emergency earthquake early warning is transmitted more reliably and evacuation is facilitated. When an earthquake with a seismic intensity of 4 or 5 or more is detected, the device protection mode is executed, and the operation of the device registered in the first device list and effective in stop control is stopped. Thereby, the operation | movement of the intended apparatus can be stopped and operation | movement of apparatuses other than these can not be stopped. For example, a medical device or the like can be excluded from the target of stop control. In addition, after receiving a seismic intensity of 4 or 5 or more after the continuous reception of the first time or the seismic detection signal, the main cut-off mode is executed after the second time has elapsed to prevent electrical fires, etc. The power supply to all devices can be cut off.

  FIG. 10 is a diagram illustrating an example of a second device list that can be used in the operation control according to the first and second embodiments. As shown in FIG. 10, the device list includes device identification information, device name, connection state, and control information, and the control information includes operation control (guidance mode), operation timing (guidance mode), and Includes stop control (equipment protection mode) based on seismic detection signals. The control unit 23 controls the operation of each device in the facility based on various received signals and the device list.

  For example, the operation timing can be set by the user terminal 4. Operation timing 0 indicates that the operation control is executed almost simultaneously with the reception of the earthquake early warning, and operation timing 0.5 indicates that the operation control is executed about 0.5 seconds after the reception of the earthquake early warning. The operation timing 1.0 indicates that the operation control is executed about 1.5 seconds after the reception of the earthquake early warning.

  That is, the control unit 23 of the home gateway device 7 causes the wireless communication unit 24 to transmit the operation control information to the device having the device identification information 0011 almost simultaneously with the reception of the earthquake early warning (at the first timing), and About 0.5 seconds after receiving the breaking news (at the second timing), the wireless communication unit 24 causes the operation control information to be transmitted to the device of the device identification information 0012, and about 1.0 seconds after receiving the earthquake early warning. At the third timing, the wireless communication unit 24 causes the operation control information to be transmitted to the device having the device identification information 0012. Thereby, the illumination of the device identification information 0011 is turned on almost simultaneously with the reception of the reception bulletin, the illumination of the device identification information 0012 is turned on about 0.5 seconds after the reception of the reception bulletin, and the illumination of the device identification information 0013 is Lights about 1.0 seconds after receiving the reception bulletin. For example, the illuminations of the device identification information 0011, 0012, and 0013 arranged in order from a distance toward the emergency exit are sequentially turned on, and the evacuation route (evacuation direction) can be easily shown to the user. The user confirms the arrangement of the illumination in advance and sets the operation timing with the user terminal, whereby the illumination can be sequentially turned on along the evacuation route. For example, it is possible to sequentially turn on lighting along an evacuation route in a commercial facility or the like.

  In addition, it is not limited only to the above-mentioned sequential lighting control, For example, control which repeats lighting and extinction sequentially so that several illuminations may flow continuously may be sufficient. Thereby, it is possible to show the evacuation route and prompt the evacuation. Alternatively, control may be performed so that predetermined illumination (for example, living illumination) blinks / extinguishes after one minute. Thereby, evacuation can be prompted.

  FIG. 11 is a diagram illustrating an example of a third device list that can be used in the operation control according to the first and second embodiments. As shown in FIG. 11, the device list includes device identification information, device name, connection state, and control information, and the control information includes operation control (guidance mode), detailed operation control (guidance mode) based on the earthquake early warning, And stop control (equipment protection mode) by seismic detection signal. The control unit 23 controls the operation of each device in the facility based on various received signals and the device list.

  For example, the detailed operation control can be set by the user terminal. The terrestrial channel 001 and the volume level 30 indicate that the terrestrial channel 001 is selected and the volume level is set to 30.

  That is, the control unit 23 of the home gateway device 7 causes the wireless communication unit 24 to transmit the operation control information and the detailed operation control information to the TV of the device identification information 0031 in response to the reception of the earthquake early warning. Thereby, the TV of the device identification information 0031 is activated in response to reception of the reception bulletin, selects the terrestrial channel 001 (outputs the program of the terrestrial channel 001), and sets the volume level 30 (volume level). 30 to output sound). As a result, it is possible to watch the broadcast of a specific channel in response to the reception of the earthquake early warning, and it is possible to notify the reception of the earthquake early warning by switching the volume (by switching to a loud volume). .

  Note that the second device list and the third device list may be combined. When combined, according to the second device list, each device operates with a time difference, for example, lighting of device identification information 0011, 0012, 0013 can be turned on in order to indicate an evacuation route, According to the device list, the TV of the device identification information 0031 is activated, the program video of the terrestrial channel 001 is output, and the sound can be output at the volume level 30.

  According to the first and second embodiments described above, it is possible to operate each device registered in the device list based on the reception of the earthquake early warning, thereby enabling notification of emergency earthquake early warning and evacuation guidance. It becomes. In addition, according to the first embodiment described above, reception of the first seismic detection signal corresponding to detection from a relatively weak earthquake to a slightly strong earthquake (or seismic detection corresponding to the detection of a predetermined level of earthquake). Since the operation of each device registered in the device list can be stopped based on the reception of the signal), it is possible to reduce the risk due to the device operated based on the reception of the earthquake early warning. Furthermore, according to the first embodiment described above, the second seismic detection signal corresponding to the detection of a strong earthquake (or the reception of the seismic detection signal corresponding to the detection of a predetermined level of earthquake for a certain period or more). ), The main circuit can be cut off and an electric fire can be prevented.

  In the above description, the operation control based on the earthquake early warning and the seismic detection signal has been described. For example, the first fire occurrence information based on pressing of the emergency button for notifying the occurrence of a fire provided in the facility, The operation control described above may be executed in combination with second fire occurrence information that detects smoke or heat and notifies the occurrence of a fire. For example, by replacing the earthquake early warning with the first fire occurrence information and replacing the seismic detection signal with the second fire occurrence information (by replacing the seismic detection sensor with smoke or heat detection sensor), the second implementation The operation control according to the embodiment can be executed.

  All procedures in the control described in the first and second embodiments can be executed by software. For this reason, the control can be easily realized only by installing and executing the program on the home gateway device 7 or the like through a computer-readable storage medium storing the program for executing the control procedure.

  For example, the home gateway device 7 or the like can read the program from a computer-readable storage medium, store the read program, and complete the installation of the program. Alternatively, the home gateway device 7 can download the program from a server or the like, store the downloaded program, and complete the installation of the program. Thereby, the home gateway device 7 can easily realize the control based on the installed program.
