The human body detecting means for detecting the disaster, the disaster information that is installed in each of the plurality of areas and that occurs in the installation area, and the disaster information is sent to the device control apparatus installed in the same area via the external network means When the disaster information is acquired, the center device generates a reply request signal that instructs the center device installed in a predetermined area different from the center device to reply. The reply request signal is transmitted to the device control apparatus installed in the same area via the external network means. And a first transmission control unit that, upon receiving the reply request signal, activates the human body detection unit, detects a change in the state of the device, and generates human body presence / absence information, A second transmission control unit configured to transmit the human body presence / absence information to the reply destination center device via the external network unit, and the reply destination center device receives the human body presence / absence information; Is transmitted to the terminal device registered in advance via the external network means.

  With this configuration, when a center device installed in an area where a disaster such as an earthquake, tsunami, landslide, typhoon, flood, or eruption has acquired disaster information, a response request signal is sent to the device control device. The device control device detects a person in the house with a human body sensor and detects a change in the state of the device, for example, on / off of a lighting fixture or opening / closing of a window or an entrance key, and a disaster occurs in human body presence / absence information. The center device is sent to the center device provided in the area that is not, and the human body presence / absence information is sent from the center device to the terminal device.Therefore, by referring to the terminal device before the actual disaster occurs, It is possible to grasp the safety information promptly.

  In addition, since the safety information can be exchanged between the center devices using an existing device control device such as a home gateway, the configuration of the safety confirmation system can be simplified, and the cost of the safety confirmation system increases. Can be prevented.

  In the safety confirmation system of the present invention, the center device includes an earthquake detection unit, and the disaster detection unit acquires earthquake information as the disaster information by detecting an initial tremor signal of an earthquake.

  With this configuration, a response request signal is transmitted from the center device to the device control device when a P wave (pitch), which is the initial tremor signal of an earthquake, is generated, so a large S wave (roll) generated after the P wave. Before the occurrence of a disaster, information on the presence or absence of human bodies can be transmitted from the equipment control device to the center device installed in an area where no disaster occurs, and even if an earthquake occurs and the building collapses, The presence or absence can be grasped and safety information can be obtained quickly.

  In addition, the device control apparatus of the safety confirmation system of the present invention operates the human body detection unit every predetermined time after receiving a reply request signal, and generates a human body presence / absence information by detecting a change in the state of the device. Then, it is comprised from the thing provided with the disaster mode setting means which transmits the said human body presence / absence information to the said center apparatus.

  With this configuration, after receiving a reply request signal, a disaster mode is set in which human body presence / absence information is generated and transmitted to the center device at regular intervals, so that the center device can be used for tsunami, landslide, typhoon, flood, eruption, etc. Safety can be ascertained until a disaster actually occurs in the area under the jurisdiction of the person or when there is a person in the house after the disaster occurs.

  For this reason, when there are people in the house, for example, there is a possibility that people who have not heard information on TV etc. or who know the information may be unable to move due to an injured person etc. In consideration of the situation, it is possible to send a family member or a local person to the home by looking at the information on the terminal device and promptly perform rescue or evacuation guidance.

  Moreover, the safety confirmation system of this invention is comprised from the said registered terminal device being a WWW server or a mobile telephone.

  With this configuration, human body presence / absence information is transmitted to a WWW server or mobile phone. When referring to a website, it is easy for an unspecified number of people to confirm safety information by referring to the human body presence / absence information via the Internet. can do.

  In FIG. 2, the HGW 3 includes an external communication unit 11, an internal communication unit 12, a timing unit 13, a storage unit 14, an input unit 15, a display unit 16, and a control unit 17, and these external communication unit 11, internal communication unit 12, a clock unit 13, a storage unit 14, an input unit 15, a display unit 16 and a control unit 17 are connected via an internal bus 18.

  The external communication unit 11 includes a modem, a TA (terminal adapter), a wireless TA, and the like, and communicates with the Internet 8 via a mobile phone 10 as a terminal device and a network infrastructure.

  The internal communication unit 12 performs data communication with the devices 21 to 24 via an internal LAN (Local Area Network) 19 as internal network means. The devices 21 to 24 are electrical appliances provided in the house 2, and are electrically operated, for example, automatic locking devices that automatically open and close keys such as televisions, video decks, lighting fixtures, windows and entrances, breakers, and surveillance cameras. Anything can be used as long as it is controlled. In the present embodiment, for convenience of explanation, four devices are illustrated, but in actuality, the same number of appliances are provided.

  The timer unit 13 includes a timer and measures time. The storage unit 14 is composed of a storage medium such as a hard disk or a CD-ROM. The storage unit 14 stores the time measured by a timer, stores family information (name, sex, etc.) in the house, and the control unit 17 Data is temporarily stored when various controls are performed.

  The input unit 15 includes various operation buttons, a keyboard, and the like, and is configured to set a home mode, input information about a family at home, and set an answering mode.

  The display unit 16 is composed of a display device such as a lamp or a liquid crystal display device, and displays that the absence mode or the home mode is set, or displays information on a family at home. Yes.

  The control unit 17 includes a CPU (Central Processing Unit) and the like, and controls the entire HGW 3. In the present embodiment, the control unit 17 controls the devices 21 to 24 according to a predetermined sequence when receiving predetermined control information for controlling the devices 21 to 24 from the mobile phone 10 via the external communication unit 11.

  For example, when receiving a command signal to turn on the luminaire from the external communication unit 11, the control unit 17 performs control to turn on the luminaire or locks the lock when receiving a command signal to lock the automatic locking device. Etc.

  In addition, a human sensor 25 as a human body detecting means is connected to the internal LAN 19, and the human sensor 25 includes a temperature sensor and an optical sensor, and when a person is located in a predetermined area of the house 2 or passes through it. When a person is detected, detection information is output to the HGW 3.

  In addition, the control unit 17 acquires detection information from the human sensor 25 and also detects the presence / absence signal of the human body (human body presence / absence information) by detecting the presence / absence of a person in the home 2 based on the state change signals from the devices 21 to 24. It is designed to generate.

  Specifically, a state change signal is generated when a lighting fixture is switched from on to off, or when a lock such as a window or an entrance is unlocked by an automatic locking device, and this state change is generated. A human body presence / absence signal is generated by combining the signal and the detection signal from the human sensor 25.

  By combining the state change signal and the detection signal in this manner, for example, the human sensor 25 may erroneously detect a human body when, for example, the human sensor 25 detects a fallen television or chance in a state where the chest has fallen. Therefore, the detection accuracy of the presence / absence of the human body can be improved by combining the detection signal from the human sensor 25 and the state change signal when the state of the devices 21 to 24 is actually changed.

  The human body presence / absence signal includes information such as the presence / absence of a human body, the address of the home 2 where the HGW 3 is installed, the name of the resident of the home 2, the sex, and the e-mail address of the mobile phone. When the state of the devices 21 to 24 changes, the elapsed time from that time is measured by the time measuring unit 13, and when a reply request signal is transmitted from the center device as will be described later, Timekeeping time may be added.

  On the other hand, the center devices 4 to 6 include, for example, local governments such as ward offices, meteorological agencies, gas companies, electric power companies, water stations, telephone offices, servers in the home 2 of each household, and the like. It is installed in each area. In the present embodiment, for convenience of explanation, three center devices 4 to 6 are illustrated, but in reality, they are provided in each region of Japan. Moreover, in this Embodiment, the center apparatuses 4-6 are demonstrated by taking the server installed in the local government as an example.

  FIG. 3 is a configuration diagram of the center devices 4 to 6. In FIG. 3, the center devices 4 to 6 include an external communication unit 31, a seismometer 32, a storage unit 33, and a control unit 34.

  The external communication unit 31 includes a modem, a TA, a wireless TA, and the like, and communicates with the Internet 8 via the mobile phone 10 as a terminal device and the network infrastructure.

  The seismometer (earthquake detection means) 32 detects the shaking state of the ground, and detects the P wave (pitch) that is the initial fine motion signal, the S wave (rolling) that occurs after the P wave, and the like. ing.

  The storage unit 33 is composed of a storage medium such as a hard disk or a CD-ROM. When an earthquake occurs, the storage unit 33 is set in the area where the earthquake occurred, for example, installed in the area where the earthquake occurred. Is the center device 4, the addresses of the center devices 5 and 6 other than the center device 4, the text posted on the website when an earthquake occurs, or the text of the e-mail returned to the mobile phone 10, the center device 4 Is stored in association with the address of the center device 5 or the center device 6 which is a reply destination of the HGW 3 set in the same area.

  In addition, the storage unit 33 stores the address of a Web site on the WWW server 9 that posts the human body presence / absence signal when the HGW 3 receives the human body presence / absence signal. This website is set up for each municipality, and each municipality operates its own website. In addition, the website may not be operated by the local government but may be operated by a police station, a fire department or the like.

  The control part 34 is comprised from CPU etc., and the control part 34 controls the whole center apparatuses 4-6. In the present embodiment, when the seismometer 32 detects a P wave, for example, a reply is sent to the center device 5 or the center device 6 for the HGW 3 provided in the same area as the area where the center device 4 is installed. A reply request signal for performing is generated, and the reply request signal is transmitted via the external communication unit 31. In the present embodiment, the external communication unit 31 and the control unit 34 constitute first transmission control means.

  On the other hand, when the HGW 3 receives this reply request signal, the HGW 3 generates a human body presence / absence signal based on the human body presence / absence signal detected by the human sensor 25 and the state change signals of the devices 21 to 24 by the control unit 17, and the human body presence / absence signal is generated. The data is transmitted to the center device 5 or the center device 6 as a reply destination designated by the external communication unit 11. In the present embodiment, the external communication unit 11 and the control unit 17 constitute a second transmission control unit.

  Note that the control unit 34 is configured to prevent a human body detection signal from being concentrated and transmitted from a large number of HGWs 3 to a specific center device at a time when the number of response request signals transmitted to the HGW 3 exceeds a predetermined number. In order to distribute to the center apparatus 5 and the center apparatus 6, the address of the distribution destination center apparatus 5 or center apparatus 6 may be added to the reply request signal and transmitted to the HGW 3.

  Further, the center devices 4 to 6 may communicate with each other, and the center devices 4 to 6 in the area where no earthquake occurs may be designated as the address of the reply request signal.

  In addition, when receiving the human body presence / absence signal from the HGW 3, the control unit 34 of the reply destination center device 5 or the center device 6 registers the human body presence / absence signal through the external communication unit 31 in a website registered in advance in the WWW server 9. Or converted into e-mail and transmitted to the mobile phone 10 registered in advance. In the present embodiment, the external communication unit 31 and the control unit 34 constitute third transmission control means.

  The HGW 3 sets the automatic disaster mode after receiving a reply request signal from the center device 4. Specifically, the control unit 17 activates the human sensor 25 every predetermined time based on the time signal from the time measuring unit 13, and detects a state change of the devices 21 to 24 to generate a human body presence / absence signal. Thereafter, the human body presence / absence signal is transmitted to the center device 5 or the center device 6 as a reply destination. In the present embodiment, the timekeeping unit 13 and the control unit 27 constitute disaster mode setting means.

  Next, the communication procedure of the safety confirmation system will be described based on the sequence diagram of FIG. In FIG. 4, the center device 4 is described as a center device in the area, and the center devices 5 and 6 are described as center devices outside the area.

  First, in the center device 4, when the seismometer 32 detects a P wave (step S10), the center devices 5 and 6 as reply destinations are designated (step S20). At this time, the center device 5 or the center device 6 designated in advance as a reply destination of the HGW 3 installed in the installation area of the center device 4 may be used as the reply destination.

  Further, when the P wave is detected, the center devices 4 to 6 communicate with each other, and the center device 5 or the center device 6 in the area where the earthquake does not occur may be a reply destination. In addition, a large number of replies from the HGW 3 are received. When expected, the reply destination may be distributed to the center device 5 or the center device 6.

  When the reply center device is designated in this way (here, the center device 5 is designated as the reply destination), a reply request signal is transmitted to the HGW 3 (step S30). When the HGW 3 receives this reply request signal, the HGW 3 determines the presence or absence of a human body based on the detection signal from the human sensor 25 and also detects the in-home state based on the operation change state of the devices 21 to 24 (step S40).

  For example, when the human sensor 25 is off and the lighting fixture is changed from on to off, the control unit 17 unlocks the lock from the locked state, and further enters the locked state. Therefore, an “absent” identifier is set in the human body presence / absence signal.

  In addition, when the human sensor 25 is on and there is no change in the state of the lighting apparatus or the automatic locking device, the control unit 17 sets the identifier “at home” in the human body presence / absence signal as indicating that the person is at home. .

  Since the state of the devices 21 to 24 is not always changed at the time of receiving the reply request signal, the control unit 17 measures the time after the state is changed by the time measuring unit 13. For example, if “15 minutes” have elapsed from when the state of the devices 21 to 24 changes until a reply request is received, time information “15 minutes” is set.

  Then, based on the identifier of “absent” or “at home”, time information, and information such as the address of the home 2 where the HGW 3 is installed, the name of the resident of the home 2, gender, and the e-mail address of the mobile phone After the presence / absence signal is generated and this human body presence / absence signal is returned to the center device 5 added to the reply request signal (step S50), the automatic disaster mode is set (step S60).

  The center device 5 analyzes the human body presence / absence signal (step S70). As the human body presence / absence information to the WWW server 9, "There is a possibility that Mr. "Please contact me if you are a family member or an acquaintance." (Step S80), and the e-mail address of your mobile phone will say "There may be a family remaining in your home. Please send a confirmation e-mail "(step S90).

  The disaster managers and family members of the local government browse the website to confirm the safety of the residents in the home 2, and the family who owns the mobile phone 10 reads the email on the mobile phone and Confirm safety.

  Further, after receiving the reply request signal, the control unit 17 of the HGW 3 activates the human sensor 25 at regular time intervals, for example, every minute, and detects a change in the state of the devices 21 to 24 (Step S100, S130), a human body presence / absence signal is generated, and the human body presence / absence signal is transmitted to the center device 5 (steps S110 and S140). Each time the center device 5 receives a human body presence / absence signal, the center device 5 executes the same processing as steps S70 to S90 (steps S120 and S150).

  Then, when the resident in the home 2 cancels the automatic disaster mode, the human body presence / absence information is not transmitted. At this time, if an automatic disaster mode release signal is transmitted to the center device 5, it is determined that a resident in the home 2 or a manager of the local government has visited the home 2 and intentionally activated the HGW 3, It can be determined that the person has taken some measures.

  As described above, in the present embodiment, when the center apparatus 4 installed in the area acquires the P wave, the reply request signal is transmitted to the HGW 3, and the HGW 3 is sent to the person 2 in the house by the human sensor 25. And detecting changes in the state of the devices 21 to 24, and transmitting a human body presence / absence signal to the center device 5 provided in an area where no earthquake has occurred. Since it is transmitted to the Web site of the server 9 and the mobile phone 10, it is possible to grasp the presence / absence of a person in the house 2 by referring to the WWW server 9 and the mobile phone 10 before a large earthquake that actually causes damage occurs. Information can be grasped promptly.

  In addition, since the safety information can be exchanged between the center devices 5 using the existing HGW 3, the configuration of the safety confirmation system 1 can be simplified, and the cost of the safety confirmation system 1 increases. Can be prevented.

  In the present embodiment, since the center devices 4 to 6 include the seismometer 32, and the earthquake information is detected by the seismometer 32 as disaster information and the disaster information is acquired, P is an initial tremor signal of the earthquake. A reply request signal can be transmitted from the center device 4 to the HGW 3 when a wave is generated.

  For this reason, before the large S wave generated after the P wave is generated, the human body presence / absence signal can be transmitted from the HGW 3 to the center device 5 installed in the area where the earthquake does not occur. Even if the computer collapses, the center device 5 can grasp the presence / absence of a person at home and promptly obtain safety information.

  In the present embodiment, the HGW 3 activates the human sensor 25 every predetermined time after receiving the reply request signal, and after detecting the state change of the devices 21 to 24 and generating the human body presence / absence signal, Since the automatic disaster mode for transmitting this human body presence / absence signal to the center device 5 is set, there is a person in the house 2 until an actual earthquake occurs in the area controlled by the center device 4 or after the earthquake occurs It is possible to grasp the safety.

  For this reason, when there are people in the home 2, for example, there are people who have not heard information on TV, etc., even if they know the information, there are elderly people who are living alone or sick people, or it is not possible to move due to actual injuries etc. In consideration of the possibility, etc., the information on the terminal device can be viewed and a family member or a local person can be dispatched to the home for prompt rescue or evacuation guidance.

  In the present embodiment, since the human body presence / absence signal is transmitted from the center device 5 to the WWW server 9 or the mobile phone 10, when referring to the website, it is not possible to refer to the human body presence / absence information through the Internet 8. A large number of specific people can easily check the safety information.

  Further, when referring to the mobile phone 10, for example, the safety information of the family can be quickly grasped by transmitting a human body presence / absence signal to the mobile phone 10 owned by the family in the home 2 installed by the HGW 3, for example. Can do.

  In addition, if there is a person who owns the mobile phone 10 in the home 2, he / she can quickly evacuate by seeing that the person has received a large earthquake by looking at the mail received by the mobile phone 10. It can be performed.

  In the present embodiment, the center device 4 distributes the center devices 5 and 6 to which the reply request signal is sent back, so that a large number of reply request signals are returned to the center device 5 or the center device 6 in one place. Thus, it is possible to prevent the communication line from being punctured and the processing in the center device from being delayed.

  In the present embodiment, the center devices 4 to 6 detect the P wave as disaster information and generate a reply request signal. However, the disaster information includes tsunami, landslide, typhoon, flood, eruption, etc. You may make it acquire disaster information.

  In this case, the center devices 4 to 6 may immediately generate a reply request signal based on disaster information such as an evacuation warning acquired from the Japan Meteorological Agency, or each of the center devices 4 to 6 may be tsunami, landslide, typhoon, Means for acquiring disaster information such as floods and eruptions may be provided.

  In the present embodiment, the center devices 4 to 6 are configured from local government servers, but as described above, servers such as the Japan Meteorological Agency, gas companies, electric power companies, water departments, telephone offices, etc. installed for each area. You may comprise. In this case, since the human body presence / absence information is transmitted and posted on a website operated by the local government, the Meteorological Agency, etc. can cooperate with the local government in the area to rescue or evacuate people in the premises 2 .

  Moreover, when the center apparatuses 4-6 are comprised from the server of each household, what is necessary is just to connect the server of relatives and friends outside an area. In the present embodiment, the human body detection means is configured by the human sensor 25 including a temperature sensor, an optical sensor, or the like, but is not limited thereto, and may be configured by a camera or the like.
