  However, the intercom system as described in Patent Document 1 notifies the occupant of the occurrence of an earthquake immediately before, and prevents secondary disasters such as fires caused by leakage of lifelines such as electricity and gas. I couldn't. Then, an object of this invention is to provide the intercom system for apartment houses which can prevent the secondary disaster of the earthquake relevant to a lifeline.

  The present invention has a dwelling unit intercom base unit connected to a lifeline meter, a lobby intercom, and a control device that controls communication thereof, and the control device includes a gateway device that is connected to a wide area network. In the home intercom system, when the control device receives an earthquake detection signal based on the earthquake early warning from the wide-area network side, the control device transmits an earthquake warning command to the dwelling unit intercom master unit. When the earthquake warning command is received, a predetermined earthquake warning is output, and a cutoff command is transmitted to the lifeline meter to cut off the lifeline.

  Here, when the dwelling unit intercom master unit receives a predetermined operation after the lifeline meter shuts off the lifeline, it transmits a resume command to the lifeline meter to resume the lifeline. Good.

  In addition, the dwelling unit intercom master unit may transmit lifeline blocking information to the wide area network side after the lifeline meter has blocked the lifeline.

  According to the present invention, the dwelling unit intercom base unit 11 blocks the lifeline immediately before the occurrence of the earthquake, so that a secondary disaster related to the lifeline can be prevented. Moreover, since it is the structure which interrupts | blocks a lifeline in each dwelling unit side, it can cut | disconnect rapidly compared with the electric power company and the gas company interrupting | blocking a lifeline by remote control, and safety improves dramatically.

It is a basic block diagram of an intercom system for collective housing to which the present invention is applied. It is a flowchart of the information transmission in a remote meter-reading. It is a flowchart of the information transmission in the interruption | blocking of lifeline, and resumption. It is a functional block diagram of a dwelling unit intercom main unit, an adapter, and a lifeline meter. It is a functional block of an alarm monitoring panel, a router device, and an earthquake receiving device.

  The intercom system 1 shown in FIG. 1 includes a dwelling unit intercom master unit 11 installed in each room of a residence building, a lobby intercom 12 installed in a common entrance, etc., and an alarm monitoring panel 13 installed in an administrator room or the like. It consists of. Although the alarm monitoring panel 13 has a function as a control device that controls communication between the dwelling unit intercom base unit 11 and the lobby intercom 12, the alarm monitoring panel 13 and the control device may be configured separately. Good. The intercom system 1 further includes an earthquake receiving device 23 that receives an earthquake detection signal through the wide area network 20 and a gateway device 18 that is connected to the wide area network 20. In addition, the dwelling unit intercom base unit 11 is connected to the alarm monitoring panel 13 via the intercom line 19. The gateway device 18 may be configured integrally with the alarm monitoring panel 13.

  A door phone slave unit 14 and a security sensor 22 are connected to the dwelling unit intercom master unit 11, and a lifeline meter 16 is connected via an adapter 15. The security sensor 22 is, for example, a fire sensor, a gas leak sensor, a security sensor, or the like. The lifeline meter 16 is, for example, a power meter, a gas meter, a water meter, etc., and may be installed in a service yard outside the dwelling unit. The adapter 15 is separate from the dwelling interphone master unit 11, but may be configured integrally.

  The wide area network 20 is connected to a meter reading server device 21 for remotely reading the lifeline meter 16 by an electric power company, a gas company, etc., and an earthquake monitoring server device 24 for distributing earthquake detection information based on emergency earthquake early warning. Yes. The earthquake monitoring server device 24 is an information distribution server of the wide area earthquake monitoring system. The wide-area earthquake monitoring system is a system in which seismometers are placed in various locations in the monitoring area, and the earthquake detection signals of those seismometers are analyzed to calculate the epicenter and seismic intensity. It is an earthquake warning signal.

  The lobby intercom 12 includes a video camera 17 for photographing a visitor, and constitutes a TV intercom system together with the dwelling unit intercom master unit 11. Here, the lobby intercom 12 has one system, but may be two systems or more if it is a large-scale apartment house or the like. The intercom system 1 may not be a TV intercom system, but may have only a call function.

  The interphone line 19 performs communication according to an interphone line protocol different from that of the wide area network 20. There, a unique interphone line address is assigned to each of the dwelling unit intercom master units 11, and conversational voice and voice between the lobby interphone 12 and the called dwelling unit interphone master unit 11 are controlled by the alarm monitoring panel 13. Visitor video is transmitted.

  The basic operation of the intercom system 1 is the same as the conventional one. That is, when a call specifying a dwelling unit number is made on the lobby interphone 12, the alarm monitoring panel 13 specifies an intercom line address corresponding to the dwelling unit number and calls the dwelling unit intercom master unit 11. When a response operation is performed at the called dwelling unit intercom base unit 11, the alarm monitoring panel 13 exclusively transmits an audio signal and a video signal between the dwelling unit intercom base unit 11 and the lobby interphone 12. As a result, a call only between the dwelling unit intercom base unit 11 and the lobby intercom 12 is allowed, and an image captured by the video camera 17 is displayed on the display unit 11 c of the dwelling unit intercom base unit 11.

  At this time, the alarm monitoring panel 13 relays communication between the dwelling unit intercom base unit 11 and the lobby intercom 12, but the dwelling unit intercom base unit 11 and the alarm monitoring panel 13 communicate by designating a transmission destination. Thus, exclusive control is possible. Communication between the alarm monitoring panel 13 and the lobby interphone 12 is basically one-to-one communication, and may be performed in a format other than the interphone line protocol. In this case, the alarm monitoring board 13 performs protocol conversion and communication relay.

  Note that the call between the dwelling unit intercom master unit 11 and the lobby intercom unit 12 is terminated by the alarm monitoring panel 13 when a termination operation is performed on the dwelling unit intercom base unit 11 or when a predetermined time has elapsed.

  The operation of the intercom system 1 as an alarm monitoring system is basically the same as the conventional one. That is, when the dwelling unit intercom base unit 11 receives an abnormality detection signal from the security sensor 22, it outputs a warning message corresponding to the type of abnormality and outputs an alarm screen. Further, an abnormality detection signal is transmitted to the alarm monitoring panel 13 through the intercom line 19. When the alarm monitoring panel 13 receives the abnormality detection signal, the alarm monitoring panel 13 specifies the dwelling unit from the source intercom line address, outputs an alarm, and transmits an alarm command signal to the dwelling unit intercom master unit 11 of the surrounding dwelling unit. Performs processing such as outputting a message loudly. Further, the alarm monitoring panel 13 may transfer the occurrence of an abnormality to a server device (not shown) of a security company through the wide area network 20 or a telephone line.

  Next, a basic operation in the remote meter reading of the lifeline meter 16 will be described.

  The meter-reading server device 21 corresponds to the registration number of the lifeline meter 16, the customer address including the customer name, residence number, and room number, and route information for reaching the lifeline meter 16 through the wide area network 20. Has a registered customer database. The route information includes at least the network address of the adapter 15 provided corresponding to each of the dwelling unit intercom base unit 11.

  The remote meter reading is performed by a procedure of transmitting a meter reading command from the meter reading server device 21 to the lifeline meter 16 side and returning meter reading information from the lifeline meter 16 side to the meter reading server device 21 as a response. The meter reading information may be voluntarily and periodically transmitted from the lifeline meter 16 side to the meter reading server device 21.

  The meter reading command designates the network address of the adapter 15 connected to one of the dwelling intercom master units 11 as a transmission destination, and is transmitted by a predetermined network protocol. The wide area network 20 includes a plurality of routers (not shown), but the meter reading instructions are successively transferred based on route information set in each of the routers and reach the gateway device 18.

  When the gateway device 18 receives the meter reading command, the gateway device 18 reads the network address of the transmission destination, and sends the meter reading command to the interphone line 19 if it is any network address of the adapter 15 installed in the residence building. . At that time, as a conversion from the network protocol to the interphone line protocol, a predetermined header or footer is added to the meter reading command. The converted meter reading command includes a broadcast interphone line address that designates all of the dwelling interphone master units 11 as a transmission destination. The interphone line address for broadcasting is a special form of the interphone line address.

  With such a configuration, the gateway device 18 can determine whether or not to read only the address of the transmission destination of the meter reading command received from the wide area network 20 and send it to the intercom line 19 in the residence. In addition, the meter reading server device 21 can generate and transmit a meter reading command without knowing the configuration of the intercom system 1, for example, the intercom line address of the dwelling unit intercom master unit 11, and the system operation becomes easy.

  The meter reading command sent to the interphone line 19 by the gateway device 18 is received by all the dwelling unit intercom base unit 11. As a protocol conversion, the dwelling unit intercom master unit 11 removes the header and footer of the interphone line protocol from the meter reading command, and outputs the meter reading command after the protocol conversion to the adapter 15.

  When the adapter 15 receives the meter reading command, the adapter 15 determines whether or not its own network address is specified as the transmission destination, and if so, outputs the meter reading command to the lifeline meter 16. On the other hand, if the network address is not designated as the transmission destination, the meter reading command is abandoned. The communication protocol between the adapter 15 and the lifeline meter 16 may be of any type.

  When the lifeline meter 16 detects a meter reading command from the adapter 15, it returns the meter reading data at that time. When the adapter 15 accepts the meter reading data, the adapter 15 generates meter reading information specifying the network address of the meter reading server device 21 as a transmission destination, and transmits the meter reading information to the dwelling interphone master unit 11.

  The dwelling unit intercom base unit 11 adds the header and footer of the interphone line protocol to the meter reading information received from the adapter 15 and sends the information to the interphone line 19. The meter reading information sent to the interphone line 19 includes the interphone line address of the gateway device 18 as a transmission destination.

  When the gateway device 18 receives the meter reading information from the interphone line 19, the gateway device 18 converts it to a network protocol by removing the header and footer of the interphone line protocol from the meter reading information, and sends it to the wide area network 20.

  The meter reading information output to the wide area network 20 has the network address of the meter reading server device 21 designated as the transmission destination, and therefore is sequentially transferred by a plurality of routers and reaches the meter reading server device 21. The meter-reading server device 21 performs processing such as reading the meter-reading information and storing it in a charging database or the like.

  A time-series flow of information transmission in the above operation is shown in FIG.

  Further, according to the present invention, when the intercom system 1 receives an earthquake detection signal based on the earthquake early warning through the wide area network 20, the lifeline can be automatically shut off. The basic operation will be described below.

  In the earthquake detection signal transmitted by the earthquake monitoring server device 24, the network address of the earthquake receiving device 23 is designated as the transmission destination. When receiving the earthquake detection signal, the earthquake receiving device 23 refers to preset location information of the residence building, etc., calculates the predicted seismic intensity of the residence building, and alerts the earthquake detection signal to which the expected earthquake intensity information is added. Output to the panel 13.

  When the alarm monitoring panel 13 receives the earthquake detection signal, if the predicted seismic intensity is equal to or higher than a preset threshold value, the alarm monitoring panel 13 transmits an earthquake alarm command to all the dwelling intercom master units 11 through the interphone line 19. The earthquake warning command includes an interphone line address for broadcasting that designates all of the dwelling unit intercom master units 11.

  Upon receiving the earthquake warning command, the dwelling unit intercom master unit 11 outputs an earthquake warning message and outputs an earthquake warning screen. Furthermore, as a characteristic operation of the present invention, the dwelling unit intercom master unit 11 transmits a lifeline cutoff command to the adapter 15 to cause the lifeline meter 16 to shut down the lifeline. In this way, if the lifeline is automatically shut off at the time of receiving the earthquake detection signal at the individual dwelling unit side, it can be shut off more quickly than the power company or gas company shuts off the lifeline by remote operation. Safety is improved dramatically.

  When the adapter 15 controls the lifeline meter 16 to shut off the lifeline, it is desirable to generate cutoff information and transmit it to a power company or gas company server on the wide area network 20. That is, block information specifying the network address of the meter reading server device 21 as a transmission destination is generated and transmitted to the dwelling unit intercom master unit 11. The procedure for transmitting the blocking information to the meter reading server device 21 by the dwelling unit intercom master unit 11 is the same as that for meter reading information. In this way, power companies and gas companies can grasp the situation more quickly and prevent confusion.

  Moreover, it is preferable that the interrupted lifeline can be resumed by performing a predetermined operation on the dwelling unit intercom master unit 11. That is, when the dwelling unit intercom base unit 11 receives the restart operation after the lifeline meter 16 blocks the lifeline, it transmits a restart command to the lifeline meter 16 to restart the lifeline. On the other hand, the adapter 15 may generate resumption information and transmit it to the power company or gas company server on the wide area network 20 through the dwelling unit intercom base unit 11. In this case, after the safety confirmation by the resident, the lifeline can be resumed, so secondary disasters and the like can be prevented.

  In addition, the time-sequential flow of information transmission in the interruption and resumption of the lifeline is shown in FIG. In addition, the lifeline can be shut off and resumed even in a system that does not perform remote meter reading. In that case, the gateway device 18 may be omitted.

  Next, the configuration of each part of the intercom system 1 will be described with reference to FIGS. 4 and 5.

Yes. When an abnormality occurs or during an earthquake, a corresponding warning message is output from the speaker of the calling unit 11b and a warning screen is displayed and output from the display unit 11f. Further, at the time of an earthquake, a cutoff command is generated and transmitted to the adapter 15, and the lifeline is shut off by the lifeline meter 16.

  In addition, when the alarm unit 11g receives a predetermined resumption operation with the operation unit 11f after the lifeline is cut off, the alarm unit 11g generates a resumption command and transmits it to the adapter 15, and the lifeline meter 16 resumes the lifeline.

  The adapter 15 includes a network communication unit 15 a that processes the network protocol and communicates with the dwelling unit intercom base unit 11, and a meter control unit 15 b that controls the lifeline meter 16.
