Description

本発明は、防災情報広域報知システムに係る発明である。   The present invention relates to a disaster prevention information wide area notification system.

従来、市町村に設けられている防災情報広域報知システムは、親局が専用波を用いて防災情報等の発信し、当該専用波を受信可能な拡声子局や戸別受信機で受信する構成である。なお、防災情報広域報知システムによっては、親局と戸別受信機等との間に中継局が介在する場合もある。また、この防災情報広域報知システムでは、戸別受信機が屋内に設置される場合が殆どである。   Conventionally, the disaster prevention information wide-area notification system provided in municipalities has a configuration in which a master station transmits disaster prevention information using a dedicated wave and receives the dedicated wave by a loudspeaker station or a separate receiver. . Depending on the disaster prevention information wide area notification system, a relay station may be interposed between the master station and the door-to-door receiver. Moreover, in this disaster prevention information wide area notification system, the door-to-door receiver is mostly installed indoors.

さらに、近年では、デジタル化された防災情報広域報知システム（具体的には、市町村デジタル同報通信システム）の配備が進んでいる。市町村デジタル同報情報システムについては、非特許文献１に詳しく説明されている。   Furthermore, in recent years, the deployment of digitized disaster prevention information wide area notification systems (specifically, municipal digital broadcast communication systems) has been progressing. The municipal digital broadcast information system is described in detail in Non-Patent Document 1.

「市町村デジタル同報通信システムの規格等に関する調査検討報告書」、社団法人 電波産業会、平成１５年３月"Survey Report on Standards of Municipal Digital Broadcast Communication Systems", The Japan Radio Industry Association, March 2003

しかし、従来の防災情報広域報知システムでは、総務省の認める親局からの出力がそれほど大きくない点、建物が軽量化のために金属パネルを多用する点及び近隣建物が高層化している点等により、戸別受信機が親局からの電界を得られない場合がある。この場合、専用アンテナを建物外部壁面等に設置することにより、戸別受信機が親局からの電界を得ることが可能になる。   However, in the conventional disaster prevention information wide area notification system, the output from the master station approved by the Ministry of Internal Affairs and Communications is not so large, the building uses a lot of metal panels to reduce the weight, and the neighboring buildings are high-rise The individual receiver may not be able to obtain the electric field from the master station. In this case, by installing a dedicated antenna on a building external wall surface or the like, the door-to-door receiver can obtain the electric field from the master station.

但し、賃貸住宅等の場合は、専用アンテナを設けることが許可されないことがある。また、戸別受信機が配備されるのは自治会長等の家である場合が多い。しかし、この自治会長等は短期間の持ち回り制であることが殆どである。そのため、自治会長等が変わる度に、専用アンテナの設置工事が必要となる。以上のような理由で、国民保護法による情報伝達手段と位置づけられた従来の防災情報広域報知システムについて、戸別受信機を設置することが自治体の負担であった。   However, in the case of rental housing, etc., it may not be permitted to provide a dedicated antenna. In addition, the door-to-door receiver is often deployed in the home of the president of the local government. However, this self-government chairman is mostly a short-term rotation system. For this reason, installation of a dedicated antenna is required every time the autonomous chairman changes. For the above reasons, it was a burden on the local government to install a separate receiver for the conventional disaster prevention information wide-area notification system, which was positioned as a means of information transmission under the National Protection Law.

また、デジタル化された防災情報広域報知システムについても、６０ＭＨｚ帯を用いるので伝送速度が限られている。そのため、自治体によっては、デジタル化された防災情報広域報知システムを導入せず、既存の防災情報広域報知システムを導入するケースがあった。   Also, the transmission speed is limited for the digitized disaster prevention information wide-area notification system because the 60 MHz band is used. For this reason, some local governments have introduced the existing disaster prevention information wide area notification system without introducing the digitized disaster prevention information wide area notification system.

そこで、本発明は、専用アンテナを設けることなく、安価に防災情報を受信できる受信機を設けた防災情報広域報知システムを提供することを目的とする。   Then, an object of this invention is to provide the disaster prevention information wide-area alerting | reporting system provided with the receiver which can receive disaster prevention information cheaply, without providing a dedicated antenna.

本発明に係る解決手段は、防災情報を専用波で発信する親局と、親局が発信する専用波を受信できる複数の専用受信機と、親局から受信した防災情報を一般に放送で使用されている電波である放送波に変換して再発信する再送信子局と、再送信子局が発信する放送波を受信できる放送受信機とを備え、再送信子局は、いずれか１つの専用受信機と、当該専用受信機に接続され放送波で放送可能な放送設備とを備え、専用受信機が防災情報を受信した場合、放送設備に割り込みが入り、放送設備は放送を中断して防災情報を放送波で発信することを特徴とする。
The solution according to the present invention is generally used in broadcasting of a master station that transmits disaster prevention information by a dedicated wave, a plurality of dedicated receivers that can receive a dedicated wave transmitted by the master station, and disaster prevention information received from the master station. A re-transmission slave station that converts a broadcast wave that is a radio wave to be retransmitted and a broadcast receiver that can receive a broadcast wave that is transmitted from the re-transmission slave station. When equipped with a receiver and broadcasting equipment connected to the dedicated receiver and capable of broadcasting on broadcast waves, when the dedicated receiver receives disaster prevention information, the broadcasting equipment is interrupted, and the broadcasting equipment interrupts the broadcasting and disaster prevention It is characterized by transmitting information by broadcast waves .

本発明に記載の防災情報広域報知システムは、親局から受信した防災情報を放送波で再発信する再送信子局を備えるので、各家庭において一般的に普及している受信機に利用することができ、専用アンテナを設ける必要もなく、安価な防災情報広域報知システムを構築することができる。また、本発明は、従来防災情報を発信できなかったエリアに対しても、放送波を利用することで容易に発信することが可能となる。   Since the disaster prevention information wide-area notification system described in the present invention includes a retransmitting slave station that retransmits the disaster prevention information received from the master station using a broadcast wave, the disaster prevention information wide-area notification system should be used for a receiver that is generally popular in each home. Therefore, it is not necessary to provide a dedicated antenna, and an inexpensive disaster prevention information wide area notification system can be constructed. Moreover, this invention can be easily transmitted by using a broadcast wave even for an area where disaster prevention information cannot be transmitted conventionally.

（実施の形態１）
図１に、本実施の形態に係る防災情報広域報知システムの概略図を示す。図１に示す防災情報広域報知システムでは、発信する防災情報（音声やデータ等の放送）を操作卓１より入力して、親局２から専用波３で発信する。そして、図１に示す防災情報広域報知システムでは、親局２からの専用波３を受信する拡声子局４及び戸別受信機５と、専用波３を放送波（一般に放送で使用されている電波、例えばＡＭ波やＦＭ波）に変換して再発信する再送信子局６とを備えている。 (Embodiment 1)
In FIG. 1, the schematic of the disaster prevention information wide-area alerting | reporting system which concerns on this Embodiment is shown. In the disaster prevention information wide area notification system shown in FIG. 1, disaster prevention information to be transmitted (broadcast such as voice and data) is input from the console 1 and is transmitted from the master station 2 by the dedicated wave 3. In the disaster prevention information wide-area broadcasting system shown in FIG. 1, the loudspeaker station 4 and the individual receiver 5 that receive the dedicated wave 3 from the master station 2, and the dedicated wave 3 are broadcast waves (generally used in broadcasting) , For example, an AM wave or an FM wave) and a retransmission slave station 6 for retransmitting.

なお、図１に示す防災情報広域報知システムでは、再送信子局６は専用波をＦＭ波７に変換して、防災情報を再送信している。そのため、当該防災情報を受信できる放送受信機として、市販されているＦＭラジオ８を利用することができる。また、拡声子局４とは、親局２から防災情報を受信し、当該防災情報をトランペットスピーカ等により放送する無線設備をいう。拡声子局４は、拡声機能を有している点で戸別受信機５とは異なるが、ともに専用波３を受信できる点では専用受信機である。   In the disaster prevention information wide-area notification system shown in FIG. 1, the retransmitting slave station 6 converts the dedicated wave into the FM wave 7 and retransmits the disaster prevention information. Therefore, a commercially available FM radio 8 can be used as a broadcast receiver that can receive the disaster prevention information. The loudspeaker station 4 is a wireless facility that receives disaster prevention information from the master station 2 and broadcasts the disaster prevention information through a trumpet speaker or the like. The loudspeaker slave station 4 is different from the door-to-door receiver 5 in having a loudspeaker function, but is a dedicated receiver in that both can receive the dedicated wave 3.

また、図１に示す再送信子局６は、既存の拡声子局に、ＦＭ波で再送信を行う機能が追加されたものである。図１に示すような拡声機能と再送信機能とを併せ持つ再送信子局６以外に、専用波３をＦＭ波７に再送信する機能のみの再送信子局であっても良い。   The retransmission slave station 6 shown in FIG. 1 is obtained by adding a function of performing retransmission using FM waves to an existing loudspeaker slave station. In addition to the retransmitting slave station 6 having both the loudspeaking function and the retransmitting function as shown in FIG. 1, a retransmitting slave station having only the function of retransmitting the dedicated wave 3 to the FM wave 7 may be used.

本実施の形態では、再送信子局６が再送信する放送波をＦＭ波７としたために、当該再送信子局６の発信可能エリアにある市販のＦＭラジオ８で、防災情報を受信することができる。そのため、再送信子局６が再送信する放送波をＡＭ波とすれば、市販のＡＭラジオで防災情報を受信することができ、再送信子局６が再送信する放送波をＶＨＦ波又はＵＨＦ波とすれば、市販のＴＶで防災情報を受信することができようになる。   In the present embodiment, since the broadcast wave to be retransmitted by the retransmitting slave station 6 is the FM wave 7, the disaster prevention information is received by the commercially available FM radio 8 in the transmittable area of the retransmitting slave station 6. Can do. Therefore, if the broadcast wave retransmitted by the retransmitting slave station 6 is an AM wave, the disaster prevention information can be received by a commercially available AM radio, and the broadcast wave retransmitted by the retransmitting slave station 6 is a VHF wave or UHF. If it is a wave, it will be possible to receive disaster prevention information on a commercial TV.

以上のように、本実施の形態に係る防災情報広域報知システムは、受信した防災情報をＦＭ波７（放送波）で再発信する再送信子局６と、再送信子局６が発信するＦＭ波７を受信できるＦＭラジオ８（放送受信機）とを備える。そのため、本実施の形態に係る防災情報広域報知システムは、各家庭において一般的に普及しているＦＭラジオ８を防災情報の受信機に利用することができ、安価な防災情報広域報知システムを構築することができる。   As described above, the disaster prevention information wide-area notification system according to the present embodiment includes the retransmission slave station 6 that retransmits the received disaster prevention information using the FM wave 7 (broadcast wave) and the FM that the retransmission slave station 6 transmits. FM radio 8 (broadcast receiver) capable of receiving the wave 7 is provided. Therefore, the disaster prevention information wide-area notification system according to the present embodiment can use the FM radio 8 that is generally popular in each home as a receiver for disaster prevention information, and constructs an inexpensive disaster prevention information wide-area notification system. can do.

また、本実施の形態に係る防災情報広域報知システムでは、限られた防災無線の周波数、もしくは限られた防災無線の出力が原因で、従来防災情報を発信できなかったエリアに対しても、ＦＭ波７（放送波）を利用することで容易に発信することが可能となる。さらに、市販のＦＭラジオ８を使用可能とすることで、高価な戸別受信機を全戸に準備する必要がなくなるとともに、専用アンテナを設ける必要もなくなる。   In addition, in the disaster prevention information wide-area notification system according to the present embodiment, FM can also be transmitted to areas where disaster prevention information cannot be transmitted conventionally due to the limited frequency of the disaster prevention radio or the output of the limited disaster prevention radio. By using the wave 7 (broadcast wave), it is possible to easily transmit. Furthermore, by making it possible to use a commercially available FM radio 8, it is not necessary to prepare expensive door-to-door receivers in all the houses, and it is not necessary to provide a dedicated antenna.

（実施の形態２）
図２に、本実施の形態に係る防災情報広域報知システムの概略図を示す。図２に示す防災情報広域報知システムでは、図１で示した拡声機能と再送信機能とを併せ持つ再送信子局６を用いず、既存のＦＭ放送設備に拡声子局を接続した再送信子局１１を用いている。 (Embodiment 2)
In FIG. 2, the schematic of the disaster prevention information wide-area alerting | reporting system which concerns on this Embodiment is shown. In the disaster prevention information wide-area broadcasting system shown in FIG. 2, the retransmission slave station in which the loudspeaker station is connected to the existing FM broadcasting equipment without using the retransmission slave station 6 having both the loudspeaker function and the retransmission function shown in FIG. 11 is used.

図２に示す防災情報広域報知システムでは、図１と同様、操作卓１から入力した防災情報を親局２から専用波３で発信する。拡声子局４及び戸別受信機５は、親局２から専用波３で発信された防災情報を受信することができる。そして、拡声子局４では受信した防災情報をトランペットスピーカ等を用いて音声として発する。また、戸別受信機５では受信した防災情報を内蔵のスピーカ等を用いて音声として発する。   In the disaster prevention information wide-area notification system shown in FIG. 2, the disaster prevention information input from the console 1 is transmitted from the master station 2 through the dedicated wave 3 as in FIG. The loudspeaker slave station 4 and the door-to-door receiver 5 can receive the disaster prevention information transmitted from the master station 2 through the dedicated wave 3. Then, the loudspeaker slave station 4 emits the received disaster prevention information as sound using a trumpet speaker or the like. The door-to-door receiver 5 emits the received disaster prevention information as sound using a built-in speaker or the like.

本実施の形態では、上記の拡声子局４及び戸別受信機５とは別に、既存のＦＭ放送設備１０（放送局又は役場の放送設備等）と、当該ＦＭ放送設備１０に接続できるインタフェースを有する拡声子局９とを備えている。つまり、本実施の形態に係る拡声子局９及びＦＭ放送設備１０が、再送信子局１１を構成する。   In the present embodiment, in addition to the above-mentioned loudspeaker slave station 4 and the door-to-door receiver 5, an existing FM broadcast facility 10 (such as a broadcast station or a broadcast facility at a public office) and an interface that can be connected to the FM broadcast facility 10 are provided. A loudspeaker slave station 9 is provided. That is, the loudspeaker slave station 9 and the FM broadcast facility 10 according to the present embodiment constitute a retransmission slave station 11.

そして、拡声子局９は、防災情報を受信するとＦＭ放送設備１０の放送に割り込む機能を有している。そのため、拡声子局９が受信した防災情報は、ＦＭ放送設備１０を経由しＦＭ波７（放送波）で発信されることになる。従って、本実施の形態に係る防災情報広域報知システムであっても、市販されているＦＭラジオ８（放送受信機）で防災情報を受信することが可能となる。   The loudspeaker slave station 9 has a function of interrupting the broadcast of the FM broadcast facility 10 when the disaster prevention information is received. Therefore, the disaster prevention information received by the loudspeaker slave station 9 is transmitted by the FM wave 7 (broadcast wave) via the FM broadcast facility 10. Therefore, even if it is the disaster prevention information wide-area alerting | reporting system which concerns on this Embodiment, it becomes possible to receive disaster prevention information with the FM radio 8 (broadcast receiver) marketed.

以上のように、本実施の形態に係る防災情報広域報知システムは、再送信子局１１が拡声子局９とＦＭ放送設備１０とを備える。そのため、本実施の形態に係る防災情報広域報知システムでは、各家庭において一般的に普及しているＦＭラジオ８（放送受信機）を防災情報の受信機に利用することができ、安価な防災情報広域報知システムを構築することができる。   As described above, in the disaster prevention information wide area notification system according to the present embodiment, the retransmission slave station 11 includes the loudspeaker slave station 9 and the FM broadcast facility 10. Therefore, in the disaster prevention information wide-area notification system according to the present embodiment, FM radio 8 (broadcast receiver) that is generally spread in each home can be used as a receiver for disaster prevention information, and inexpensive disaster prevention information. A wide area notification system can be constructed.

また、本実施の形態に係るの再送信子局１１は、実施の形態１の再送信子局６のように専用の再送信機能を持たせる必要がなく、既存のＦＭ放送設備１０と専用受信機（拡声子局９等）とを単に接続するだけで良い。そのため、本実施の形態に係る防災情報広域報知システムでは、再送信子局を安価に導入することができる。さらに、本実施の形態では、既存のＦＭ放送設備１０を利用するため、防災情報を再送信する以外の時は、通常の放送を行うことができ設備の利用効率が高くなる。   Further, unlike the retransmission slave station 6 of the first embodiment, the retransmission slave station 11 according to the present embodiment does not need to have a dedicated retransmission function, and is dedicated to the existing FM broadcast equipment 10 and dedicated reception. It is only necessary to simply connect a machine (amplifying slave station 9 or the like). Therefore, in the disaster prevention information wide area notification system according to the present embodiment, the re-transmission slave station can be introduced at low cost. Furthermore, in the present embodiment, since the existing FM broadcasting facility 10 is used, normal broadcasting can be performed except when the disaster prevention information is retransmitted, and the utilization efficiency of the facility is increased.

なお、本実施の形態では、ＦＭ放送設備１０に拡声子局９を接続する構成であったが、本発明はこれに限られず、親局２が発信する専用波を受信可能な専用受信機であれば良く、ＦＭ放送設備１０と接続可能な戸別受信機５でも良い。   In the present embodiment, the loudspeaker station 9 is connected to the FM broadcast facility 10, but the present invention is not limited to this, and is a dedicated receiver that can receive a dedicated wave transmitted from the master station 2. What is necessary is just the door-to-door receiver 5 that can be connected to the FM broadcasting facility 10.

（実施の形態３）
図３に、本実施の形態に係る防災情報広域報知システムの概略図を示す。図３に示す防災情報広域報知システムでは、親局２、拡声子局３及び戸別受信機５以外に、インターネット（ＩＰ網１６）に接続可能なパーソナルコンピュータ（以下、ＰＣともいう）１４と接続している戸別受信機１２をさらに備える構成である。 (Embodiment 3)
In FIG. 3, the schematic of the disaster prevention information wide-area alerting | reporting system which concerns on this Embodiment is shown. In the disaster prevention information wide-area notification system shown in FIG. The door-to-door receiver 12 is further provided.

図３に示す操作卓１から入力した防災情報を、親局２から専用波３を用いて発信する。拡声子局４及び戸別受信機５は、親局２から専用波３で発信された防災情報を受信することができる。そして、拡声子局４では受信した防災情報をトランペットスピーカ等を用いて音声として発する。また、戸別受信機５では受信した防災情報を内蔵のスピーカ等を用いて音声として発する。   Disaster prevention information input from the console 1 shown in FIG. 3 is transmitted from the master station 2 using the dedicated wave 3. The loudspeaker slave station 4 and the door-to-door receiver 5 can receive the disaster prevention information transmitted from the master station 2 through the dedicated wave 3. Then, the loudspeaker slave station 4 emits the received disaster prevention information as sound using a trumpet speaker or the like. The door-to-door receiver 5 emits the received disaster prevention information as sound using a built-in speaker or the like.

図３に示す防災情報広域報知システムでは、拡声子局４及び戸別受信機５への発信と平行して、戸別受信機１２がＩＰ網１６に接続可能なＰＣ１４に対して防災情報のデータを伝送する。戸別受信機１２は、戸別受信機５と同様、専用波３を受信可能であり、親局２からの防災情報を受信する。なお、図３では戸別受信機１２とＰＣ１４とは有線１３で接続されているが、本発明はこれに限られず、無線であっても良い。   In the disaster prevention information wide area notification system shown in FIG. 3, the disaster prevention information data is transmitted to the PC 14 that can be connected to the IP network 16 by the door receiver 12 in parallel with the transmission to the loudspeaker 4 and the door receiver 5. To do. Similarly to the door-to-door receiver 5, the door-to-door receiver 12 can receive the dedicated wave 3 and receives disaster prevention information from the master station 2. In FIG. 3, the door-to-door receiver 12 and the PC 14 are connected by the wire 13, but the present invention is not limited to this and may be wireless.

一方、ＰＣ１４は、有線１５にて一般に整備されているＩＰ網１６に接続されている。そのため、ＰＣ１４は、戸別受信機１２より得た防災情報に関連した情報をＩＰ網１６から取得することができる。   On the other hand, the PC 14 is connected to an IP network 16 that is generally maintained by a cable 15. Therefore, the PC 14 can acquire information related to the disaster prevention information obtained from the door-to-door receiver 12 from the IP network 16.

つまり、親局２と戸別受信機４，１２等との通信では輻輳を生じさせない程度の小さな伝送容量の防災情報が発信されている。従って、ＰＣ１４には、小さな伝送容量の防災情報が表示されるだけである。しかし、ＰＣ１４はＩＰ網１６に接続されているため、ユーザがさらに詳細な防災情報、もしくは関連情報を知りたい場合には、ＰＣ１４に表示されている防災情報のリンクを選択することで、より大容量の情報を得ることが可能になる。   That is, disaster prevention information with a transmission capacity that is small enough not to cause congestion is transmitted in communication between the master station 2 and the individual receivers 4 and 12. Therefore, the disaster prevention information with a small transmission capacity is only displayed on the PC 14. However, since the PC 14 is connected to the IP network 16, if the user wants to know more detailed disaster prevention information or related information, the user can select a disaster prevention information link displayed on the PC 14 to increase the disaster prevention information. Capacity information can be obtained.

なお、ＰＣ１４とＩＰ網１６との接続は有線１３に限られず、無線であっても良い。また、ＰＣ１４の接続先は、ＩＰ網１６に限られず電話回線網等の既存の通信回線網であっても良い。   The connection between the PC 14 and the IP network 16 is not limited to the wired line 13 and may be wireless. Further, the connection destination of the PC 14 is not limited to the IP network 16 and may be an existing communication line network such as a telephone line network.

本実施の形態に係る防災情報広域報知システムは、戸別受信機１２が受信した防災情報に関する情報（さらに詳細な防災情報、もしくは関連情報）を取得可能なＩＰ網１６（通信回線網）に接続された情報処理装置であるＰＣ１４を備えている。そのため、本実施の形態に係る防災情報広域報知システムは、極めて限られた伝送速度しか持たないシステムにおいて、ユーザが望めば、さらに詳しい大容量の情報を得ることが可能となる。   The disaster prevention information wide area notification system according to the present embodiment is connected to an IP network 16 (communication line network) that can acquire information (more detailed disaster prevention information or related information) related to disaster prevention information received by the individual receiver 12. PC 14 as an information processing apparatus is provided. Therefore, the disaster prevention information wide-area notification system according to the present embodiment can obtain more detailed information on a large volume if the user desires in a system having an extremely limited transmission rate.

また、本実施の形態に係る防災情報広域報知システムでは、送信機能を有しない戸別受信機４，１２がＰＣ１４を介してＩＰ網１６と接続することにより、ＡＣＫや情報の送信が可能となる。ＰＣ１４に接続された戸別受信機１２を用いると、具体的に、独居老人宅の緊急呼び出し等が可能となる。さらに、ＩＰ網１６を介して戸別受信機４，１２のソフトウェア等をアップデートやサポート等を行うことが可能となる。   Moreover, in the disaster prevention information wide-area notification system according to the present embodiment, the ACK and information can be transmitted by connecting the receivers 4 and 12 having no transmission function to the IP network 16 via the PC 14. When the door-to-door receiver 12 connected to the PC 14 is used, it is possible to make an emergency call or the like of a nursing home alone. Further, it becomes possible to update or support the software of the individual receivers 4 and 12 via the IP network 16.

（実施の形態４）
図４に、本実施の形態に係る防災情報広域報知システムの概略図を示す。図４に示す防災情報広域報知システムでは、親局２の設備の一部である操作卓１が直接ＩＰ網１６（通信回線網）に接続された構成である。 (Embodiment 4)
In FIG. 4, the schematic of the disaster prevention information wide-area alerting | reporting system which concerns on this Embodiment is shown. In the disaster prevention information wide-area notification system shown in FIG.

図４に示す防災情報広域報知システムにおいても、操作卓１から入力された防災情報は、親局２から専用波３を用いて発信される。拡声子局４及び戸別受信機５は、親局２から専用波３で発信された防災情報を受信することができる。そして、拡声子局４では受信した防災情報をトランペットスピーカ等を用いて音声として発する。また、戸別受信機５では受信した防災情報を内蔵のスピーカ等を用いて音声として発する。   Also in the disaster prevention information wide-area notification system shown in FIG. 4, the disaster prevention information input from the console 1 is transmitted from the master station 2 using the dedicated wave 3. The loudspeaker slave station 4 and the door-to-door receiver 5 can receive the disaster prevention information transmitted from the master station 2 through the dedicated wave 3. Then, the loudspeaker slave station 4 emits the received disaster prevention information as sound using a trumpet speaker or the like. The door-to-door receiver 5 emits the received disaster prevention information as sound using a built-in speaker or the like.

さらに、図４に示す防災情報広域報知システムでは、親局２から防災情報を発信するのと並行して、防災情報もしくは当該防災情報よりも詳細な情報を、ＩＰ網１６経由して接続インタフェース１８で接続されたＰＣ１９等に情報を送信する。   Further, in the disaster prevention information wide area notification system shown in FIG. 4, the disaster prevention information or more detailed information than the disaster prevention information is transmitted via the IP network 16 in parallel with the transmission of the disaster prevention information from the master station 2. The information is transmitted to the PC 19 or the like connected by.

なお、接続インタフェース１８としては、例えばＬＡＮや電話回線などがある。また、接続インタフェース１８は、有線であっても無線であっても良い。さらに、操作卓１から防災情報等をＩＰ網１６経由して受け取れる端末として、ＰＣ１９以外に携帯電話や携帯情報端末などであっても良い。また、本実施の形態では、ＩＰ網１６としているがこれに限られず、防災情報等を伝送可能な通信回線網であれば良い。   Examples of the connection interface 18 include a LAN and a telephone line. The connection interface 18 may be wired or wireless. Furthermore, as a terminal that can receive disaster prevention information or the like from the console 1 via the IP network 16, a mobile phone or a portable information terminal may be used in addition to the PC 19. In the present embodiment, the IP network 16 is used. However, the present invention is not limited to this, and any communication network that can transmit disaster prevention information or the like may be used.

以上のように、本実施の形態に係る防災情報広域報知システムは、防災情報を専用波で発信し、且つ当該防災情報を通信回線網（ＩＰ網１６）に送信可能な親局を備えている。そのため、本実施の形態に係る防災情報広域報知システムでは、極めて限られた伝送速度しか持たない親局２から戸別受信機５等への発信以外に、より多くの情報を伝達することができるＩＰ網１６を介した親局からＰＣ１９等への情報送信が可能となる。また、本実施の形態に係る防災情報広域報知システムでは、メール等を利用することにより、携帯電話等にも防災情報を送信することが可能となる。   As described above, the disaster prevention information wide area notification system according to the present embodiment includes a master station capable of transmitting disaster prevention information by a dedicated wave and transmitting the disaster prevention information to the communication network (IP network 16). .

Further, if the broadcasting facility 20 is a CATV (cable) broadcasting facility, the broadcast wave 21 is transmitted via a wire, and disaster prevention information can be received by the TV receiver 22 (broadcast receiver) connected by the wire. It becomes possible.

また、放送設備２０から防災情報等を発信する場合、まず操作卓１から防災情報を入力すると放送設備２０に割り込みが入る。そして、放送設備２０は、当該割り込みにより放送を中断し、防災情報を発信する。   When disaster prevention information or the like is transmitted from the broadcast facility 20, when the disaster prevention information is first input from the console 1, the broadcast facility 20 is interrupted. And the broadcasting equipment 20 interrupts broadcasting by the said interruption, and transmits disaster prevention information.

以上のように、本実施の形態に係る防災情報広域報知システムは、親局２に接続された放送波２１で放送可能な放送設備２０を備えている。そのため、本実施の形態に係る防災情報広域報知システムは、限られた周波数や出力しか許可されていない親局２から戸別受信機５等への通信システム以外に、既存の放送設備２０の放送エリアに防災情報を伝達するシステムを有することのなる。また、既存の放送設備２０を利用するので、本実施の形態に係る防災情報広域報知システムは安価に構築することができる。   As described above, the disaster prevention information wide area notification system according to the present embodiment includes the broadcasting facility 20 capable of broadcasting on the broadcast wave 21 connected to the master station 2. Therefore, the disaster prevention information wide area notification system according to the present embodiment is not limited to the communication system from the master station 2 to which the limited frequency or output is permitted to the individual receiver 5 or the like. Will have a system to communicate disaster prevention information. Moreover, since the existing broadcasting equipment 20 is utilized, the disaster prevention information wide-area notification system according to the present embodiment can be constructed at a low cost.
