Control.

  The business service processing unit 35 b is a processing unit that monitors the operation and failure state of each functional unit of the business service unit 34 and transmits it to the shared server 20. When the security / disaster prevention unit 34a of the business service unit 34 detects the crime prevention / disaster prevention information, the business service processing unit 35b receives the crime prevention / disaster prevention information and notifies the shared server 20 of the information. In addition, the aggregate value of the gas, water, and electricity usage in the dwelling unit is received from the HEMS unit 34b, and the usage amount of the dwelling unit is periodically transmitted to the shared server 20.

  The information distribution unit 35c is a processing unit that distributes information inside and outside the dwelling unit. The information distribution unit 35c distributes and receives not only the information in the Internet communication but also the electronic circulation board, the data broadcast in the housing complex 200, the life-related information, and the like by the LAN communication in the dwelling and the dwelling unit.

  The security management unit 35d is a processing unit that monitors the security status of the entire dwelling unit, blocks communication by unauthorized intrusion and malware, and ensures the normality of the devices in the dwelling unit. By interlocking with the security management of the shared server 20, the security protection of the dwelling unit can be enhanced. Specifically, a security function necessary for a dwelling unit is added by combining hardware and software such as a firewall and IDS / IPS.

  Next, the network configuration of the collective facility optical communication system 100 will be described. FIG. 7 is a diagram showing an example of a network configuration of the collective-facility optical communication system 100 using a four-core optical fiber. As shown in FIG. 7, the network configuration of the optical communication system 100 for collective facilities using a four-core optical cable Ch includes an internet network 61, a broadcast network 62, and a crime prevention / disaster prevention network 63 for each core. And the network 64 for HEMS is comprised. In FIG. 7, the configurations of the networks 61 to 64 in the information communication central management room 10 are indicated by broken lines.

  The networks 61 and 62 are a network for the Internet and a network for viewing the television by the personal computer 51 and the television 52 connected to the dwelling unit server 30. In the personal computer 51 and the television 52, the electrical signal is converted into an optical signal by the dwelling server 30, and the optical signal is transmitted directly to an external public communication network via the Internet and a two-core optical cable for television broadcasting and the self-standing terminal device 12, respectively. It is sent as it is. Reception is in the reverse order of transmission. As described above, the networks 61 and 62 are used as communication and broadcasting networks dedicated to dwelling units.

  On the other hand, in the networks 63 and 64, the crime prevention / disaster prevention terminal 53 and the HEMS terminal 54 are connected to the shared server 20 from the dwelling server 30 by a single-core optical cable. The two networks 63 and 64 are information management networks in the apartment house.

  The networks 61 and 62 are open networks using two cores of the four-core optical cable Ch. That is, it is a network that communicates with the outside using a communication provider and a broadcaster that are freely selected in each dwelling unit, and the shared server 20 is not involved in this communication. In addition, each dwelling unit can add a functional unit to the indoor 19-inch rack 40 to perform communication unique to the device manufacturer.

  Note that, with the exception of rental equipment such as V-ONUs and distributors, the Internet and broadcasting are mostly configured by connection work within the information communication central management room 10. For this reason, if a rental device such as a terminal device such as a V-ONU is liberalized, the rental device is not necessary in order to be able to incorporate such a terminal device into the dwelling unit server 30, and the telecommunications carrier must enter the dwelling unit. Sex is almost lost.

  The networks 63 and 64 are relatively closed networks using two cores of the four-core optical cable Ch. The crime prevention / disaster prevention terminal 53 and the HEMS terminal 54 are connected to the dwelling unit server 30, and the shared server 20 is connected to the dwelling unit server 30 via the self-propelled termination device 12 with one-core optical fiber cables for crime prevention / disaster prevention and energy status grasping. Connected to. The networks 63 and 64 using the two cores are for information management in the apartment house 200, and are operated for centralized information distribution and reception by the shared server 20.

  Specifically, the shared server 20 distributes and receives the crime prevention / disaster prevention information to the crime prevention / disaster prevention terminal 53 of the dwelling unit, and distributes the HEMS information (electric power consumption, etc.) to a data center such as a trader. is there. Basically, the two networks 63 and 64 have a form in which the shared server 20 communicates with outside persons on behalf of the apartment house 200.

  The information that the shared server 20 delivers to the data center of the supplier is not limited to the amount of power used by the HEMS. For example, each dwelling unit is provided with a measuring unit for water and gas as well as electricity, and the dwelling unit server 30 aggregates and transmits the usage amount to the shared server 20, which uses a single optical cable. The measurement information can be distributed to each data center through the public network. It is also possible to distribute the usage fee details from the data center to the dwelling units.

  In addition, it is technically possible to perform meter reading in which the dwelling unit server 30 collects the electricity, gas, and water usage of each dwelling unit for each dwelling unit and transmits it to the shared server 20, which is compatible with electric smart grids and efficient gas. Effective measures such as use and water-saving measures are also possible. Moreover, since the shared server 20 communicates with an external data center in an integrated manner without newly subscribing a communication line, a dwelling unit that does not contract the Internet can perform efficient communication.

  The network 63 for crime prevention / disaster prevention and the network 64 for HEMS are in the form of a LAN in which the shared server 20 and the dwelling unit are closed in the apartment house 200. As for the outside, the shared server 20 communicates with the data center, the disaster prevention center, and the like in a centralized manner. Any one of the two-core networks may be used to transmit and receive other equipment-related signals specific to the housing complex, such as intercom and equipment monitoring signals.

  As described above, the optical communication system 100 for collective facilities shown in FIG. 7 has two network forms. That is, there are two networks: an open network in which each dwelling unit is independently connected to the Internet, etc., and an information management closed network in the apartment house 200 in the LAN form of the shared server 20 and dwelling unit server 30.

  Since the two networks are also mixed on the shared server 20 and the dwelling unit server 30, it is desirable to separate the networks from each other. For this reason, it separates in a network segment or divides a protocol to prevent mutual interference of information. In particular, including the protection of personal information, the security management unit 23 of the shared server 20 is used from the viewpoint of security to prevent information leakage from inside and outside.

  In the first embodiment, the case where the four-core optical cable Ch is used for communication, broadcasting, crime prevention / disaster prevention and HEMS is described. However, the purpose of use of the four-core optical cable Ch is not limited to this. In addition, the communication for crime prevention / disaster prevention and HEMS can be made into 1 core, and the remaining 1 core can also be made into a reserve.

  Next, in the optical communication system for collective facilities 100, a processing procedure of a network configuration until a resident of each dwelling unit selects a communication carrier and can communicate will be described. FIG. 8 is a flowchart showing a processing procedure until communication is possible using the communication carrier selected by the resident.

  When a resident newly selects a telecommunications carrier or changes a telecommunications carrier, he / she issues a line setting request from the personal computer 51 to the shared server 20 via the dwelling server 30. The shared server 20 receives the line setting request (step S101), selects the communication carrier indicated in the line setting request by the system management unit 25c of the control unit 25 (step S102), and selects the selected communication carrier. A line setting request is output to the communication carrier through the communication unit (step S103).

  When receiving the line setting request output from the shared server 20, the communication carrier transmits an acceptance notice including a line connection schedule to the shared server 20. The shared server 20 receives the reception notification from the communication carrier (step S104), and notifies the resident of the line connection schedule included in the reception notification (step S105). The telecommunications carrier and the house management company perform a connection test based on the line connection schedule, and perform a line setting completion operation when the connection test is completed. The shared server 20 determines whether or not a line setting completion operation has been accepted (step S106). If the line setting completion operation has not been accepted (step S106; No), the process moves to step S106 and waits for the line setting completion operation. To do.

  When the line setting completion operation is received (step S106; Yes), the shared server 20 updates the connection state of the system (step S107) and ends the process.

  Next, a communication processing procedure in which the shared server 20 centrally transmits and receives gas, electricity, water metering information, operation monitoring of home equipment, and the like will be described. FIG. 9 is a flowchart for explaining the communication processing procedure of the shared server 20 when the electronic message communication is received. In addition, since disaster prevention is mentioned in Example 2, only a common part is demonstrated here.

  When the shared server 20 receives a message (step S201), it is determined whether the received message relates to a shared service such as crime prevention / disaster prevention or HEMS (step S202). When the received message is related to the shared service (step S202; Yes), the shared server 20 determines whether the received message is related to the HEMS information (step S203). If the received message is related to the HEMS information (step S203; Yes), the total value of electricity, gas, and water in the dwelling unit is read from the received message (step S204) and stored as dwelling unit information (step S205).

  After step S205, the shared server 20 determines whether or not it is necessary to notify the data center of the total value read from the message (step S206). If it is determined that the notification of the total value is necessary (step S206; Yes), the shared server 20 notifies the data center of the total value read from the message (step S207). After completion of step S207, or when it is determined that notification is not necessary (step S206; No), the shared server 20 determines whether or not the usage fee details to be notified to the dwelling unit exist in the data center. (Step S208). If there is no usage fee detail to be notified to the dwelling unit in the data center (step S208; No), the shared server 20 ends the process. If the usage fee specification to be notified to the dwelling unit exists in the data center (step S208; Yes), the shared server 20 transmits the usage fee specification to the dwelling unit server 30 (step S209), and ends the process.

  If the message received in step S201 relates to the shared service (step S202; Yes), but is not HEMS information (step S203; No), the received message is a message indicating crime prevention / disaster prevention information. Therefore, the shared server 20 reads crime prevention / disaster prevention information from the received electronic message (step S210). The shared server 20 determines whether it is necessary to distribute the read crime prevention / disaster prevention information to all the dwelling units in the residence building (step S211).

  When it is determined that the read crime prevention / disaster prevention information needs to be distributed to all the dwelling units in the residence building (step S211; Yes), the shared server 20 delivers the read crime prevention / disaster prevention information to all the residence units in the residence building. (Step S212).

  After step S212, or when it is determined that the read crime prevention / disaster prevention information need not be distributed to all the dwelling units in the residence building (step S211; No), the shared server 20 needs to report to the disaster prevention organization or the like. It is determined whether or not there is (step S213).

  If it is determined that a report to the disaster prevention organization or the like is necessary (step S213; Yes), the shared server 20 reports to the disaster prevention organization or the like (step S214) and ends the process. If it is determined that a report to a disaster prevention organization or the like is not required (step S213; No), the crime prevention / disaster prevention information is uploaded to an electronic circulation board that can be read by the resident (step S215), and the process is terminated.

  If the message received in step S201 is not related to the shared service (step S202; No), the shared server 20 reads out the home unit status information of the dwelling unit stored in the unified format in the message (step S216). After step S216, shared server 20 updates the device status record (step S217), performs notification processing on operation terminal 24 (step S218), and ends the process.

  In the first embodiment, the case where four functional units related to communication, broadcasting, crime prevention / disaster prevention, and HEMS are used has been described. However, the optical communication system 100 for collective facilities is not limited to this. Further, the network form of the optical communication system 100 for collective facilities is not limited to the form disclosed in the first embodiment. By adding functional units according to future service modes, it is possible to expand the system by planned arrangement of units such as full-fledged smart grid, distance education, remote diagnosis and meter reading agency.

  In addition, regarding the smart grid and the like, since the shared server 20 centrally manages information about dwelling units, it is desirable to strictly manage security from the viewpoint of protecting personal information. For this reason, the form which secures the security of the whole residence with the shared server 20, and adds required security for every dwelling unit in conjunction with it is also possible.

  In the first embodiment, the four-core optical cable Ch is installed in each dwelling unit, but is not limited to the four-core, and any cable such as an eight-core optical cable can be used. When using an 8-core optical cable in high-rise apartments, etc., use 4 cores for communication, broadcasting, crime prevention / disaster prevention, and HEMS, and use the remaining 4 cores for base station antenna wiring as a countermeasure for eliminating radio wave interruptions in mobile phones. It may be used for This is because mobile phone radio waves may be difficult to reach, especially on higher floors, and measures are taken to eliminate radio wave interruptions in buildings. If one core is connected to the up and down of one mobile phone company, base station antenna wiring of two mobile phone companies can be performed with four cores.

  In the case of disaster prevention information, it is necessary to share the same accurate information in a short time even if the contracted telecommunication carriers are different dwelling units. In the second embodiment, a case will be described in which disaster prevention information that arrives early is acquired and all the dwelling units are notified of this disaster prevention information equally regardless of which communication provider each dwelling unit has contracted.

  FIG. 10 is a functional block diagram illustrating the configuration of the shared server 110 according to the second embodiment. As shown in FIG. 10, the shared service unit 22 of the shared server 110 is provided with a crime prevention / disaster prevention unit 26, and the control unit 25 is provided with a disaster prevention information processing unit 27. Since other configurations and operations are the same as those of the shared server 20 of the first embodiment shown in FIG. 3, the same components are denoted by the same reference numerals and description thereof is omitted.

  The shared server 110 is connected to the local disaster prevention system and a plurality of communication carriers, etc., and the shared server 110 always collects disaster prevention information and centrally distributes emergency and accurate disaster prevention information to all units. The crime prevention / disaster unit 26 is a unit that is connected to disaster monitoring of a security company, a local disaster prevention system, and a communication carrier's line, collects disaster prevention information from these systems, etc., and reports it to the apartment house 200. The crime prevention / disaster prevention unit 26 transmits to the disaster prevention information processing unit 27 the received disaster prevention information such as fire, earth disaster, natural disaster, etc., information provider, and contents.

  The disaster prevention information processing unit 27 always keeps the disaster prevention information received from the crime prevention / disaster prevention unit 26 up-to-date, and when the received disaster prevention information is newer than the existing disaster prevention information, the disaster prevention information is stored in each dwelling unit server 30. In addition to distributing to the crime prevention / disaster prevention unit 34a, the stored disaster prevention information is updated. Of the four networks 61 to 64 using four cores, the network that can distribute information in the shortest time is a network 63 for crime prevention / disaster prevention. Therefore, the disaster prevention information processing unit 27 distributes disaster prevention information to all dwelling units using the crime prevention / disaster prevention network 63.

  In addition, the disaster prevention information processing unit 27 is for emergency broadcast communication that is set in advance in the system management unit 25c so that the disaster prevention information is distributed equally to each unit regardless of which telecommunications carrier has a contract with the unit. Make settings for disaster prevention information delivery. The disaster prevention information is distributed from the disaster prevention information processing unit 27 to the dwelling unit server 30 via the communication unit 12 by this disaster prevention information distribution setting. Thereby, disaster prevention information is processed with the highest priority and distributed to each dwelling unit server 30.

  Further, particularly in case of urgent necessity, it may be linked with the in-house broadcasting by the recorded voice in the apartment house 200 or an alarm device. In this case, the disaster prevention information processing unit 27 issues an alarm instruction through the alarm device when the emergency disaster prevention information is received, issues an alarm all at once in the apartment house 200, and conveys the first report to the residents, Information distribution will be conducted with the primary purpose of taking prompt action. In the second embodiment, this is called a simultaneous alarm net. Thereafter, the shared server 20 delivers detailed disaster prevention information to each dwelling unit. For this reason, even when a resident is not in a dwelling unit but in a common area such as a corridor, disaster prevention information can be quickly distributed. Depending on the type of disaster prevention information, it is preferable that several types of recording voices and warning sounds are prepared.

  Note that whether or not the emergency information is urgently distributed to the dwelling units may be conditional or unconditional. For example, the weather forecast such as heavy rain or lightning may be more than a warning. However, in the second embodiment, in consideration of the case where there is no time to evacuate after receiving an alarm as in the case of an earthquake, notification is made unconditionally when a forecast is issued and when it occurs. .

  Disaster prevention information is not limited to natural disasters such as earthquakes and tsunamis, thunderstorms, and floods linked to them. When the disaster prevention information processing unit 27 receives a report from a certain dwelling unit or tenant, such as a neighborhood fire, gas leak warning and private fire report, etc., it may be necessary to promptly notify the specified dwelling unit and the apartment housing disaster prevention center to respond. is there. In this case, the disaster prevention information processing unit 27 receives a report from the dwelling unit or the dwelling unit server 30 of the resident and notifies all the dwelling units.

  Similarly, when a certain dwelling unit uses a disaster prevention unit such as a security company as a functional unit of the dwelling server 30, information from the disaster prevention unit can also be incorporated into the disaster prevention information. In this case, when the disaster prevention unit in the dwelling unit server 30 receives the disaster prevention information from the security company or the like, the disaster prevention information processing unit 27 of the shared server 110 is notified to the shared server 110 using the crime prevention / disaster prevention network 63. If it determines with the disaster prevention information received from 30 being newer than the existing information, disaster prevention information will be transferred with respect to all the dwelling unit servers 30 other than the transmitted dwelling unit. As a result, the disaster prevention information from the security company registered in the dwelling unit server 30 is automatically distributed to the dwelling units in the residence building via the disaster prevention information processing unit 27 of the shared server 110.

  FIG. 11 is a flowchart showing a processing procedure for distributing disaster prevention information to the residence building by the shared server 110. When the shared server 110 receives the disaster prevention information from the dwelling server 30 (step S301), the disaster prevention information processing unit 27 determines whether or not the received disaster prevention information is newer than the existing information already stored in its own device ( Step S302). If the received disaster prevention information is not newer than the existing information already stored in the own device (step S302; No), the shared server 110 ends the process.

  When the disaster prevention information received from the dwelling unit server 30 is newer than the existing disaster prevention information (step S302; Yes), the disaster prevention information processing unit 27 needs to distribute the received disaster prevention information within the residence building. Is determined (step S303).

  If it is determined that the received disaster prevention information needs to be distributed within the residence building (step S303; Yes), the disaster prevention information processing unit 27 determines whether or not to alert the received disaster prevention information through the simultaneous alarm network. (Step S304). If it is determined that an alarm is to be issued through the simultaneous alarm net (step S304; Yes), the disaster prevention information processing unit 27 issues an alarm through the simultaneous alarm net (step S305).

  After the alarm by the simultaneous alarm net (step S305) is completed or when the alarm by the simultaneous alarm net is not performed (step S304; No), the disaster prevention information processing unit 27 uses the disaster prevention information received from the dwelling unit server 30 for crime prevention / Distribution to all the dwelling units by the network 63 for disaster prevention (step S306). After step S306, the disaster prevention information processing unit 27 updates the disaster prevention information held by the own device with the disaster prevention information received from the dwelling unit server 30 (step S307), and ends the process. When the simultaneous alarm net is not used in step S303 (step S303; No), disaster prevention information is distributed to all the dwelling units (step S306), the disaster prevention information of the own device is updated (step S307), and a series of processes Exit.

  As described above, it is important for disaster prevention information to promptly notify all the dwellers of the first report, which enables the dwelling units to respond quickly. In the second embodiment, all communication carriers and broadcasters with whom the shared server 110 has contracted in the apartment house 200 and disaster prevention information such as regional disaster prevention systems are centrally collected and the latest disaster prevention information is distributed to each unit. This makes it possible to respond quickly.

  In addition to transmitting emergency disaster prevention information as in the second embodiment, a disaster prevention information web is established as a disaster prevention network in the apartment house 200, and disaster information of communication companies, broadcasters, and various disaster prevention systems is provided. You can also build a system that allows browsing.

  In the second embodiment, the effect of centralized information delivery by the collective-facility optical communication system 100 is not limited to sharing disaster prevention related information. The form of receiving information centrally and flowing it centrally can be considered in various situations in terms of daily life. The second embodiment can also be applied when emergency transmission of hygiene information such as crime prevention and infectious diseases is required.

  In the optical communication system 100 for collective facilities disclosed in the first and second embodiments, measures against lightning damage are particularly important. Therefore, it is preferable that the collective facility optical communication system 100 is a system including lightning protection measures. When an overcurrent generated by induced lightning or the like enters the apartment house 200 from a power line, a communication line, or the like, an IP-related device operating at a low voltage is fragile. For this reason, lightning arresters such as SPD (Surge Protection Device) are provided in the communication and power supply lines. Specifically, a lightning arrester such as an SPD may be installed in the communication and power line of the self-standing termination device 12, the shared server 20, the IDF 13, and the dwelling unit server 30 of the collective facility optical communication system 100.

  In the said Example 1 and 2, although demonstrated taking the case of the apartment house, the present invention is not limited to an apartment house. As described above, it is naturally applicable to office buildings and the like. Further, if a detached house is one household of an apartment house and the entire community is regarded as an apartment house, it is possible to realize the optical communication system 100 for collective facilities of the entire community.

  In the first and second embodiments, the information communication central management room 10 is installed in the room or server room where the MDF (Main Distribution Frame) is installed together with the termination device of the communication carrier. As explained. However, if the information central management room 10 cannot be newly established or expanded in an existing facility or the like, the information communication central management room 10 is an outdoor storage box equipped with a 19-inch rack, and equipment is stored in this storage box on the rooftop. Is possible. The outdoor storage box can be a storage box that can be configured in various ways, depending on the configuration of the optical communication system 100 for collective facilities. This storage box enables wiring to the information communication central management room 10 without affecting the waterproofing on the roof.

  As described above, since the integrated wiring is made to each dwelling unit by the four-core optical cable Ch, when the terminal is updated, it is only necessary to replace the terminal equipment. For this reason, life extension of an apartment house etc. is achieved. Also, in the future, even if PCs, TVs, telephone terminals, etc. will be compatible with optical connections and all-optical wiring is used, it is only necessary to replace conventional metal cables with optical fibers and change the connection outlets to optical outlets. New technology can be easily introduced without damaging the wiring equipment.

  The collective-facility optical communication system according to the present invention is suitable for a case where a tenant wants to realize flexibility that allows a resident to freely select each telecommunications carrier and handling capability to quickly provide information related to a disaster or the like.
