既存の情報提供システムでは、防災行政無線の屋外拡声子局から気象情報や河川情報を拡声放送するようにしており、情報提供の単位となる拡声区域(エリア)は比較的広域である。ようするに如何なる情報を如何なるエリアに通知するかは大雑把である。戸別宅内に設置される戸別受信機を用いても、提供される情報は同様である。システムの高機能化にあたってはエリアをさらに局地化させ、また、動的に変化させられる機能などが要求されるがこのような技術は未だ知られていない。
目的は、危険地域の周辺住民にきめ細かく情報を提供できるようにした情報提供システムとその親局装置、および情報提供方法を提供することにある。
In the existing information provision system, weather information and river information are broadcasted from an outdoor loudspeaker station of the disaster prevention administrative radio, and the loudspeak area (area) as a unit of information provision is relatively wide. Thus, what information is notified to which area is roughly determined. The information provided is the same even when a door-to-door receiver installed in the door-to-door home is used. In order to increase the functionality of the system, the area is further localized, and a function that can be dynamically changed is required, but such a technique is not yet known.
An object is to provide an information providing system, a master station apparatus, and an information providing method capable of providing detailed information to residents in the vicinity of a dangerous area.

実施形態によれば、情報提供システムは、親局と複数の子局とを備える。親局は、少なくとも雨に関する自然現象データを提供する防災データ提供システムに接続される。各子局は、地域内のエリアごとに配置されエリア内に防災情報を提供する。親局は取得部、雨量予測部、水位予測部、データベース、判定部、特定部を備える。取得部は防災データ提供システムから自然現象データを取得する。雨量予測部は取得した自然現象データに基づいて地域内における雨量分布を予測する。水位予測部は取得した自然現象データに基づいて地域内における河川の水位分布を予測する。データベースは複数の子局のそれぞれの位置情報を記憶する。判定部は雨量分布および水位分布の少なくとも一方に基づいて、防災情報を提供すべきエリアを判定する。特定部は判定されたエリアに対応する子局を位置情報に基づいて特定し、当該特定した子局に防災情報を提供させる。   According to the embodiment, the information providing system includes a master station and a plurality of slave stations. The master station is connected to a disaster prevention data providing system that provides at least natural phenomenon data related to rain. Each slave station is arranged for each area in the area and provides disaster prevention information in the area. The master station includes an acquisition unit, a rainfall prediction unit, a water level prediction unit, a database, a determination unit, and a specifying unit. The acquisition unit acquires natural phenomenon data from the disaster prevention data provision system. The rainfall prediction unit predicts the rainfall distribution in the area based on the acquired natural phenomenon data. The water level prediction unit predicts the water level distribution of the river in the area based on the acquired natural phenomenon data. The database stores position information of each of the plurality of slave stations. The determination unit determines an area where disaster prevention information should be provided based on at least one of the rainfall distribution and the water level distribution. The specifying unit specifies a slave station corresponding to the determined area based on the position information, and causes the specified slave station to provide disaster prevention information.

図1は、実施形態に係わる情報提供システムの一例を示すシステム図である。このシステムは、庁舎などに設置される防災行政無線親局設備100を中核として、この防災行政無線親局設備100と無線通信する屋外拡声子局201〜20n、戸別受信機211〜21nを備える。屋外拡声子局201〜20n、戸別受信機211〜21nは、対象とする地域内の複数のエリアごとに配置され、エリア内に防災情報を提供する。   FIG. 1 is a system diagram illustrating an example of an information providing system according to the embodiment. The system includes outdoor loudspeaker stations 201 to 20n and door-to-door receivers 211 to 21n that communicate wirelessly with the disaster prevention administrative radio master station facility 100, with the disaster prevention administrative radio master station facility 100 installed in a government office or the like as a core. The outdoor loudspeaker stations 201 to 20n and the individual receivers 211 to 21n are arranged for each of a plurality of areas in the target area, and provide disaster prevention information in the areas.

防災行政無線親局設備(以下、親局設備と称する)100は、無線送受信装置110、操作卓120および気象情報入力部130を備える。操作卓120と気象情報入力部130とは、庁舎内に設置されるInternet protocol(IP)ネットワーク401などを介して接続される。   The disaster prevention administrative radio base station facility (hereinafter referred to as “base station facility”) 100 includes a radio transmission / reception device 110, an operation console 120, and a weather information input unit 130. The console 120 and the weather information input unit 130 are connected via an Internet protocol (IP) network 401 or the like installed in the government building.

気象情報入力部130は、IPネットワーク400などを介して他設備防災システム300に接続される。他設備防災システム300は少なくとも雨に関する自然現象データを提供するもので、例えば気象庁から提供されるデータベースなどを含む。このほか地震や降雪、霧などの気象現象に関する情報も他設備防災システム300から提供されることができる。   The weather information input unit 130 is connected to the other facility disaster prevention system 300 via the IP network 400 or the like. The other facility disaster prevention system 300 provides at least natural phenomenon data relating to rain, and includes, for example, a database provided by the Japan Meteorological Agency. In addition, information on weather phenomena such as earthquakes, snowfall, and fog can be provided from the other facility disaster prevention system 300.

無線送受信装置110は屋外拡声子局201〜20n、および戸別受信機211〜21nに無線回線を介して接続される。
屋外拡声子局201〜20nは音声拡声部としての拡声スピーカを備え、親局設備100から提供された防災情報が周辺地域に拡声放送される。戸別受信機211〜21nは住民の住宅内に設置され、親局設備100から提供された防災情報が戸別受信機内蔵のスピーカから放送される。屋外拡声子局201〜20nおよび戸別受信機211〜21nは文字表示機能を備え、親局設備100から提供された文字情報を表示できるようになっている。
The wireless transmission / reception apparatus 110 is connected to outdoor loudspeaker slave stations 201 to 20n and door-to-door receivers 211 to 21n via wireless lines.
The outdoor loudspeaker slave stations 201 to 20n are equipped with loudspeakers serving as voice loudspeakers, and disaster prevention information provided from the master station facility 100 is broadcasted to the surrounding area. The door-to-door receivers 211 to 21n are installed in residents' homes, and disaster prevention information provided from the master station equipment 100 is broadcast from speakers built into the door-to-door receiver. The outdoor loudspeaker stations 201 to 20n and the individual receivers 211 to 21n have a character display function, and can display character information provided from the master station facility 100.

図2は、図1に示される気象情報入力部130の一例を示す機能ブロック図である。気象情報入力部130は実施形態に係わる処理ブロックとして受信部130a、雨量予測部130b、水位予測部130c、エリア判定部130d、子局位置情報データベース(DB)130e、エリア位置情報DB130f、音声合成部130g、および、文字情報提供部130hを備える。   FIG. 2 is a functional block diagram showing an example of the weather information input unit 130 shown in FIG. The weather information input unit 130 includes a receiving unit 130a, a rainfall prediction unit 130b, a water level prediction unit 130c, an area determination unit 130d, a slave station location information database (DB) 130e, an area location information DB 130f, and a speech synthesis unit as processing blocks according to the embodiment. 130g and a character information providing unit 130h.

このうち子局位置情報DB130eには、屋外拡声子局201〜20nの拡声区域のエリア情報(GIS:Geographic Information System)、および戸別受信機211〜21nの位置情報(緯度、経度)が予め格納される。エリア位置情報DB130fには、対象エリアとなる市町村などの区域、境界、河川などのGIS情報が予め格納される。   Among these, in the slave station position information DB 130e, area information (GIS: Geographic Information System) of the loudspeaker areas of the outdoor loudspeaker slave stations 201 to 20n and position information (latitude and longitude) of the individual receivers 211 to 21n are stored in advance. The The area position information DB 130f stores in advance GIS information such as areas such as municipalities, boundaries, and rivers that are target areas.

受信部130aは、他設備防災システム300からレーダ情報(降雨状況、降雨予測)などの気象情報、あるいは河川の水位などの河川情報を収集する。いずれの情報も自然現象データの一例である。
雨量予測部130bは、受信部130aから気象情報を受け取り、将来の降雨量、雨量分布などをエリアごとに予測する。水位予測部130cは受信部130aから河川情報を受け取り、将来の水位分布、河川の氾濫区域などをエリアごとに予測する。
The receiving unit 130a collects meteorological information such as radar information (rainfall status, rainfall prediction) or river information such as a river level from the other equipment disaster prevention system 300. Any information is an example of natural phenomenon data.
The rainfall prediction unit 130b receives weather information from the reception unit 130a and predicts future rainfall, rainfall distribution, and the like for each area. The water level prediction unit 130c receives the river information from the reception unit 130a, and predicts the future water level distribution, the flooded area of the river, and the like for each area.

エリア判定部130dは、予測された雨量分布、水位分布に基づいて、防災情報を提供すべきエリアを判定する。またエリア判定部130dは、判定されたエリアに対応する子局、すなわち当該エリアを受け持つ屋外拡声子局、戸別受信機を特定する。つまりエリア判定部130dは、拡声放送を起動すべきエリアもしくは屋外拡声子局、戸別受信機を判定する。   The area determination unit 130d determines an area where disaster prevention information should be provided based on the predicted rainfall distribution and water level distribution. In addition, the area determination unit 130d specifies a slave station corresponding to the determined area, that is, an outdoor loudspeaker slave station and a door-to-door receiver that are responsible for the area. That is, the area determination unit 130d determines the area where the loudspeaker broadcasting should be started, the outdoor loudspeaker station, and the individual receiver.

音声合成部130g、文字情報提供部130hは、エリア判定部130dから予測結果およびエリア判定結果を受け取り、提供すべき防災情報を生成する。すなわち音声合成部130gは、防災情報を放送すべきエリアに向けた内容の音声データを防災情報に基づいて合成する。文字情報提供部130hは、文字情報提供のための文字データを防災情報に基づいて生成する。   The voice synthesis unit 130g and the character information provision unit 130h receive the prediction result and the area determination result from the area determination unit 130d, and generate disaster prevention information to be provided. That is, the voice synthesizing unit 130g synthesizes voice data having contents directed to the area where the disaster prevention information should be broadcast based on the disaster prevention information. The character information providing unit 130h generates character data for providing character information based on the disaster prevention information.

またエリア判定部130dは、予測結果およびエリア判定結果を音声合成部130gおよび文字情報提供部130hに渡し、防災情報に基づき合成された音声データ、文字データを受け取る。さらにエリア判定部130dは、放送対象となる屋外拡声子局および戸別受信機の情報、放送内容の音声データ、文字情報提供のための文字データを操作卓120に渡す。   The area determination unit 130d passes the prediction result and the area determination result to the voice synthesis unit 130g and the character information providing unit 130h, and receives voice data and character data synthesized based on the disaster prevention information. Furthermore, the area determination unit 130d passes the information about the outdoor loudspeaker stations and door-to-door receivers to be broadcasted, the audio data of the broadcast contents, and the character data for providing character information to the console 120.

図3は、各屋外拡声子局201〜20nの拡声区域のエリア情報を模式的に示す図である。拡声区域は拡声放送が聞こえる範囲と捉えることができる。図中実線は行政境界(例えば市境)を示し、点線が拡声エリアを示す。図3においては行政境界をカバーするよう拡声エリアが配置される様子を示すが、必ずしも全ての領域をカバーする必要はない。図2の子局位置情報DB130eにはこの拡声区域のGIS情報が格納されている。また、戸別受信機211〜21nの位置情報(緯度、経度)も子局位置情報DB130eに格納されている。   FIG. 3 is a diagram schematically showing area information of the loudspeaker areas of the outdoor loudspeaker slave stations 201 to 20n. The loudspeaker area can be regarded as the range where loudspeaker broadcasting can be heard. In the figure, a solid line indicates an administrative boundary (for example, a city boundary), and a dotted line indicates a loudspeaker area. Although FIG. 3 shows a state where the loudspeaker area is arranged to cover the administrative boundary, it is not always necessary to cover the entire area. The slave station position information DB 130e in FIG. 2 stores the GIS information of this loudspeaker area. The position information (latitude and longitude) of the individual receivers 211 to 21n is also stored in the slave station position information DB 130e.

図4は、雨量予測部130bによる予測結果の一例を示す図である。例えば現在時刻を14:00とすると時間の経過とともに降雨域の移動することが示される。図4においては20分ごとの予測が示される。   FIG. 4 is a diagram illustrating an example of a prediction result by the rainfall prediction unit 130b. For example, if the current time is 14:00, it indicates that the rainfall area moves with time. In FIG. 4, prediction every 20 minutes is shown.

図5は、降雨域と拡声エリアとが重なる領域が時間の経過とともに変化することを模式的に示す図である。雨量予測結果(図4)が移動するので、降雨域と拡声エリアとが重なる領域も時間の経過とともに変化する。エリア判定部130dは降雨域の予測値と子局位置情報DB130e、エリア位置情報130fの情報とをもとに、降雨域と拡声区域とが重なる屋外拡声子局を抽出する。エリア判定部130dはこの結果に基づいて、各時刻での予測雨量と拡声機能を起動すべき屋外拡声子局の情報とを操作卓120に渡す。   FIG. 5 is a diagram schematically showing that the region where the rainfall region and the loudness area overlap changes with the passage of time. Since the rainfall prediction result (FIG. 4) moves, the region where the rainfall region and the loudspeaking region overlap also changes over time. The area determination unit 130d extracts outdoor loudspeaker slave stations where the rainy zone and the loudspeaker region overlap, based on the predicted value of the rainy region, the slave station location information DB 130e, and the information of the area location information 130f. Based on this result, the area determination unit 130d passes the predicted rain amount at each time and information on the outdoor loudspeaker station to activate the loudspeaker function to the console 120.

なお戸別受信機211〜21nにおいても、エリア判定部130dは、子局位置情報DB130eに格納されている戸別受信機211〜21nの位置情報(緯度、経度)と雨量予測結果(図4)とを元に、降雨域と重なる戸別受信機を抽出する。そしてエリア判定部130dはその結果、すなわち各時刻での予測雨量と放送機能を起動すべき対象の戸別受信機の情報を操作卓130dに渡す。   In each of the individual receivers 211 to 21n, the area determination unit 130d uses the position information (latitude and longitude) of the individual receivers 211 to 21n stored in the slave station position information DB 130e and the rainfall prediction result (FIG. 4). Originally, the receivers that overlap the rainfall area are extracted. Then, the area determination unit 130d passes the result, that is, the predicted rainfall amount at each time and the information of the target individual receiver to activate the broadcast function to the console 130d.

図6は、水位予測部130cによる予測結果の一例を示す図である。図6には河川の氾濫区域が示される。
図7は、河川氾濫区域と拡声エリアとの重なりを模式的に示す図である。エリア判定部130dは、図6に示される河川氾濫区域の予測結果とエリア位置情報DB130fに記憶されるエリアの位置情報とを照らし合わせ、河川氾濫区域に重なり合うエリアを判定する。さらにエリア判定部130dは、判定したエリアに対応する屋外拡声子局、戸別受信機を子局位置情報データベース(DB)130eの位置情報と照らし合わせ、防災情報を提供させるべき屋外拡声子局、戸別受信機を抽出する。エリア判定部130dは、抽出した屋外拡声子局、戸別受信機を操作卓120に送信する。
FIG. 6 is a diagram illustrating an example of a prediction result by the water level prediction unit 130c. FIG. 6 shows a flooded area of the river.
FIG. 7 is a diagram schematically showing the overlap between the river flooding area and the loudspeaker area. The area determination unit 130d compares the prediction result of the river flooding area shown in FIG. 6 with the area position information stored in the area position information DB 130f, and determines an area overlapping the river flooding area. Furthermore, the area determination unit 130d compares the outdoor loudspeaker station and the door-to-door receiver corresponding to the determined area with the position information of the slave station position information database (DB) 130e, and provides the outdoor loudspeaker station and door-to-door that should provide disaster prevention information. Extract the receiver. The area determination unit 130d transmits the extracted outdoor loudspeaker station and the door-to-door receiver to the console 120.

図8は、実施形態に係わる親局設備100により実施される処理手順を示すフローチャートである。親局設備100はまず、レーダ情報(降雨状況、降雨予測)などの気象情報や河川の水位などの河川情報を、定期的に、あるいはポーリングなどにより他設備防災システム300から受信する(ステップS101)。これらの情報は受信部130aから雨量予測部130bおよび水位予測部130cに渡される。   FIG. 8 is a flowchart showing a processing procedure performed by the master station equipment 100 according to the embodiment. First, the master station equipment 100 receives weather information such as radar information (rainfall status, rainfall prediction) and river information such as river water level from the other equipment disaster prevention system 300 periodically or by polling (step S101). . These pieces of information are passed from the receiving unit 130a to the rainfall prediction unit 130b and the water level prediction unit 130c.

雨量予測部130bは、渡された気象情報を用いて降雨量の分布などを予測し、その結果をエリア判定部130dに渡す。水位予測部130cは、渡された河川情報を用いて河川の氾濫区域や水位分布などを予測し、その結果をエリア判定部130dに渡す(ステップS102)。   The rainfall prediction unit 130b predicts the distribution of rainfall using the passed weather information and passes the result to the area determination unit 130d. The water level prediction unit 130c predicts a flooded area, a water level distribution, and the like of the river using the passed river information, and passes the result to the area determination unit 130d (step S102).

エリア判定部130dは、雨量分布、水位分布、河川の氾濫区域の予測結果などに基づいて、エリア位置情報DB130fに格納されている市町村などの区域、境界、河川などのGIS情報を参照し、降雨が予測される区域、河川の氾濫が予測される区域を、防災情報を提供すべきエリアとして判定する。   The area determination unit 130d refers to the GIS information such as the municipalities, boundaries, rivers, etc. stored in the area position information DB 130f based on the rainfall distribution, the water level distribution, the prediction result of the flooded area of the river, etc. Are determined as areas where disaster prevention information should be provided.

またエリア判定部130dは、屋外拡声子局201〜20nの拡声区域のエリア情報、戸別受信機211〜21nの位置情報(子局位置情報DB130e)を参照して、判定されたエリアに対応する屋外拡声子局および戸別受信機を抽出する(ステップS103)。   The area determination unit 130d refers to the area information of the loudspeaker areas of the outdoor loudspeaker slave stations 201 to 20n and the position information of the individual receivers 211 to 21n (slave station positional information DB 130e), and the outdoor corresponding to the determined area. A loudspeaker slave station and a door-to-door receiver are extracted (step S103).

次に、音声合成部130gはエリア判定部130dから予測結果およびエリア判定結果を防災情報として受け取り、放送すべき内容の音声データを合成してエリア判定部130dに返す。また文字情報提供部130h、はエリア判定部130dから予測結果およびエリア判定結果を防災情報として受け取り、文字情報提供のための文字データを生成してエリア判定部130dに返す(ステップS104)。またエリア判定部130dは、抽出した屋外拡声子局および戸別受信機の情報、放送内容の音声データおよび文字情報提供のための文字データを操作卓120に渡す。   Next, the speech synthesis unit 130g receives the prediction result and the area determination result as the disaster prevention information from the area determination unit 130d, synthesizes the voice data of the content to be broadcast, and returns it to the area determination unit 130d. The character information providing unit 130h receives the prediction result and the area determination result as the disaster prevention information from the area determining unit 130d, generates character data for providing character information, and returns the character data to the area determining unit 130d (step S104). In addition, the area determination unit 130d passes the extracted outdoor loudspeaker station and door-to-door receiver information, broadcast content audio data, and character data for providing character information to the console 120.

最後に、これらの情報は操作卓120から無線送受信装置110に渡され、該当する屋外拡声子局および戸別受信機に対して放送内容が放送される(ステップS105)。すなわち操作卓120がエリア判定部130dから受け取った拡声放送対象の屋外拡声子局の情報および放送対象の戸別受信機の情報、音声データおよび文字データは、無線送受信装置110を経由して、対象の屋外拡声子局および戸別受信機に無線で通知される。これを受けた屋外拡声子局および戸別受信機は、受信した放送内容を音声で拡声放送したり、文字表示したりする。   Finally, these pieces of information are transferred from the console 120 to the wireless transmission / reception device 110, and the broadcast contents are broadcast to the corresponding outdoor loudspeaker station and the individual receiver (step S105). That is, the information on the outdoor loudspeaker station to be loudspeaked and the information on the individual receiver to be broadcast, the voice data, and the character data received by the console 120 from the area determination unit 130d are transmitted via the wireless transmission / reception device 110. It is notified wirelessly to the outdoor loudspeaker station and the door-to-door receiver. Receiving this, the outdoor loudspeaker station and the door-to-door receiver broadcast the received broadcast content by voice or display characters.

図9は、比較のため既存の防災行政無線システムを示す図である。図9のシステムにおいては防災に係わる気象情報、河川情報を職員が自ら収集し、市町村の防災親局設備の操作者に与えることで、防災情報が周辺住民に伝達されていた。このため情報収集に手間取ったりするとその分、住民への情報伝達が遅れることになる。また、マンパワーに依存する部分が大きく、対策を講じる余地があった。さらには、エリア、時間、情報内容を考慮して拡声区域(エリア)を動的に変化させ住民に周知させることはできなかった。   FIG. 9 is a diagram showing an existing disaster prevention administrative radio system for comparison. In the system shown in FIG. 9, the staff collected the weather information and river information related to disaster prevention and gave them to the operators of the disaster prevention master station equipment in the municipalities, so that the disaster prevention information was transmitted to the surrounding residents. For this reason, if it takes time to collect information, information transmission to the residents will be delayed accordingly. In addition, there was a large part depending on manpower, and there was room for taking measures. Furthermore, it was not possible to dynamically change the loudspeaker area (area) in consideration of the area, time, and information content and to inform the residents.

図10は、比較のため既存の防災行政無線システムの他の例を示す図である。このシステムはモバイル通信システムを利用して、災害時において要支援者への注意喚起をメールなどで行うシステムである。前提となるシステムが、モバイル端末を備えるモバイル通信システムであるので、本発明の想定する課題を解決することはできない。   FIG. 10 is a diagram showing another example of an existing disaster prevention administrative radio system for comparison. This system is a system that uses a mobile communication system to alert a support recipient in the event of a disaster by e-mail or the like. Since the presupposed system is a mobile communication system including mobile terminals, the problem assumed by the present invention cannot be solved.

図11は、比較のため既存の防災行政無線システムの他の例を示す図である。このシステムは自治体の行政区域の境界にとらわれずに緊急通報を行おうとするものであるが、やはりモバイル通信システムを前提とするものであるので、本発明の想定する課題を解決することはできない。   FIG. 11 is a diagram illustrating another example of an existing disaster prevention administrative radio system for comparison. This system is intended to make an emergency call without being bound by the boundaries of the administrative area of the local government. However, since this system is also premised on the mobile communication system, the problem assumed by the present invention cannot be solved.

これに対し実施形態では、親局設備100に気象情報入力部130を備え、他設備防災システム300から気象情報や河川情報を取得し、それらの情報に基づいて、警報を発すべきエリアを予測する。各エリアに対応する屋外拡声子局および戸別受信機の位置は予めデータベース化されて親局設備100に記憶されており、予測されたエリアを受け持つ屋外拡声子局および戸別受信機を特定して、防災情報を発報させるようにする。すなわち警報を発令すべきエリアを詳細に特定し、拡声放送・文字情報提供を適切なエリアに適切なタイミングで実施するようにしている。これにより単純な一斉放送にとどまらず、必要な人に適切なタイミング(予測して事前に通知)で防災情報を提供することができる。   In contrast, in the embodiment, the master station facility 100 includes a weather information input unit 130, acquires weather information and river information from the other facility disaster prevention system 300, and predicts an area where an alarm should be issued based on the information. . The location of the outdoor loudspeaker station and the door-to-door receiver corresponding to each area is stored in the base station equipment 100 in advance as a database, and the outdoor loudspeaker station and the door-to-door receiver serving the predicted area are identified, Make disaster prevention information available. In other words, the area where the alarm should be issued is specified in detail, and the sound broadcasting and text information provision are performed in an appropriate area at an appropriate timing. As a result, it is possible to provide disaster prevention information not only for simple simultaneous broadcasting but also for necessary people at an appropriate timing (predicted and notified in advance).

実施形態の情報提供システムによれば、例えば、広域のレーダ雨量情報に連動して動的に拡声区域を変化させて拡声放送、文字情報提供を実施したり、河川の水位情報から該当する拡声区域のみに拡声放送・文字情報提供をすることなどが可能となる。従って周辺住民に対して情報をよりきめ細かく提供することが可能になり、効果的な注意喚起、避難誘導などが行えるようになる。
これらのことから、危険地域の周辺住民にきめ細かく情報を提供できるようにした情報提供システムとその親局装置および情報提供方法を提供することが可能となる。
According to the information providing system of the embodiment, for example, the loudspeaker broadcasting and text information provision are performed by dynamically changing the loudspeaker area in conjunction with radar rainfall information over a wide area, or the relevant loudspeaker area is determined from the river water level information. It is possible to provide voice broadcasting and text information only. Therefore, it becomes possible to provide information to neighboring residents in more detail, and effective alerting and evacuation guidance can be performed.
As a result, it is possible to provide an information providing system, a master station apparatus, and an information providing method capable of providing detailed information to residents in the vicinity of the dangerous area.

なお本発明は上記実施形態に限定されるものではない。例えば図8のフローチャートにおけるステップS103では、防災情報を提供すべきエリアとして降雨が予測されるエリア、河川の氾濫が予測される区域を判定し、これらに対応する屋外拡声子局および戸別受信機を抽出するようにした。   The present invention is not limited to the above embodiment. For example, in step S103 in the flowchart of FIG. 8, areas where rainfall is predicted as areas where disaster prevention information should be provided and areas where rivers are predicted to be flooded are determined, and outdoor loudspeaker stations and door-to-door receivers corresponding to these areas are determined. I tried to extract.

この処理にあたり、降雨が予測される区域と河川の氾濫が予測される区域とを、OR条件またはAND条件で合わせた地域に対応する、屋外拡声子局および戸別受信機を抽出するようにしても良い。あるいは、降雨が予測される区域または河川の氾濫が予測される区域を別々に判定し、それぞれの区域ごとに、対応する屋外拡声子局および戸別受信機を戸別に抽出するようにしても良い。   In this process, outdoor loudspeaker stations and individual receivers that correspond to areas where the areas where rainfall is predicted and the areas where rivers are expected to overflow are combined using the OR condition or AND condition may be extracted. good. Alternatively, an area where rainfall is predicted or an area where river flooding is predicted may be determined separately, and a corresponding outdoor loudspeaker station and door-to-door receiver may be extracted for each area.

本発明の実施形態を説明したが、この実施形態は例として提示するものであり、発明の範囲を限定することは意図していない。この新規な実施形態は、その他の様々な形態で実施されることが可能であり、発明の要旨を逸脱しない範囲で、種々の省略、置き換え、変更を行うことができる。この実施形態やその変形は、発明の範囲や要旨に含まれるとともに、特許請求の範囲に記載された発明とその均等の範囲に含まれる。   Although an embodiment of the present invention has been described, this embodiment is presented as an example and is not intended to limit the scope of the invention. The novel embodiment can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. This embodiment and its modifications are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
