本発明は、防災や行政（広報など）の防災行政無線回線により無線電波を送信する統制局からの電波を受信し、屋外で拡声する防災行政無線設備の屋外拡声子局（屋外で拡声する局）に設置されるスピーカの音響到達エリアを決定するに際し、その検討作業において画面上で模擬しながら実施することを可能とする防災行政無線設備屋外拡声子局用音響到達エリア模擬システムにおいて、市町村名を入力し、対応する市町村地図を表示させ、また、屋外拡声子局設置位置とその音響到達エリア図を地図上に階層的に重ねて表示させ、さらに屋外拡声子局の位置や音響到達エリア図を変更しながら、その地域に最適な屋外拡声子局の位置と音響到達エリア図を模擬することができる構成を提供するものである。
【００１４】
（第１の実施の形態の構成）図１は、本発明の防災行政無線設備屋外拡声子局用音響到達エリア模擬システムに係る第１の実施の形態を示すブロック図である。
【００１５】
防災行政無線設備屋外拡声子局用音響到達エリア模擬システムは、入力装置１、データ処理装置２、記憶装置３、出力装置４とを含んで構成される。
【００１６】
入力装置１は、ユーザーが市町村（自治体）名を入力するキーボード等を含んで構成されている。
【００１７】
データ処理装置２は、音響到達エリア描画手段２１と音響到達エリア編集手段２２とを含んでおり、屋外拡声子局の音響到達エリア図を、出力装置４の画面に表示された地図上に描き、屋外拡声子局のスピーカの方向や音響到達エリア図の変更、あるいは屋外拡声子局の位置の変更等の作業を画面上で模擬する。
【００１８】
音響到達エリア描画手段２１は、地図データベース３１の地図データを入力装置１から入力された市町村名を基に検索し、出力装置４の画面上に表示させ、次に屋外拡声子局情報データベース３２を検索し、屋外拡声子局情報データベース３２の情報の内、屋外拡声子局の位置、スピーカの種類、数量、出力ワット数、方向、音響到達エリアパターンを基に屋外拡声子局の音響到達エリア図を市町村の地図上に描く。
【００１９】
音響到達エリア編集手段２２は、表示されている音響到達エリア図を変更する場合、ユーザーが、対象となる屋外拡声子局を選択（例えば、屋外拡声子局をマウスで直接クリックして指定する、屋外拡声子局名をキーボードで入力して指定する、屋外拡声子局番号をキーボードで入力して指定する）すると、屋外拡声子局情報データベース３２に登録されている情報が画面に表示されるので、ユーザーはこの情報を変更することにより、スピーカの方向や音響到達エリア図の変更、あるいは屋外拡声子局の設置位置の変更等の作業を画面上で模擬することを可能にするものである。これにより、ユーザーは、画面上に表示された屋外拡声子局の位置や音響到達エリア図を見ながら直感的な操作により、市町村の地域に最適な屋外拡声子局の位置や音響到達エリア図を模擬しながら事前（屋外拡声子局の設置後に行われるスピーカの方向などの調整）に決定できるので、現場での作業効率の向上と設置後の音響到達エリアのメンテナンス作業の負担を極力減少させるものである。
【００２０】
記憶装置３は、市町村の地図データや屋外拡声子局の位置、スピーカの種類などの屋外拡声子局情報を記憶しており、地図データベース３１と屋外拡声子局情報データベース３２とを含んでいる。
【００２１】
地図データベース３１は、屋外拡声子局が設置される市町村および屋外拡声子局が設置されている市町村の地図データ等が登録され格納されている。
【００２２】
屋外拡声子局情報データベース３２は、設置予定および設置されている屋外拡声子局に関する情報（屋外拡声子局の位置、屋外拡声子局のスピーカの種類、数量、出力ワット数、方向（向き）、音響到達エリアパターン等）が屋外拡声子局毎に登録され、格納されている。ここでいう音響到達エリアパターンとは、スピーカの種類によって決まる音響指向性図である。つまり、この発明では、音響到達エリアパターンを、スピーカの方向に応じて回転させたり、出力ワット数に応じて音響が到達するエリアを拡大・縮小したり、屋外拡声子局の設置位置に対応させて移動させたりしている。
【００２３】
出力装置４は、市町村地図や音響到達エリア図を表示するデスプレイと、市町村地図や音響到達エリア図を出力するプリンタ等を含んで構成される。
【００２４】
（第１の実施の形態の動作）次に、図１及び図２を参照して第１の実施の形態の動作について詳細に説明する。図２は、本発明の防災行政無線設備屋外拡声子局用音響到達エリア模擬システムに係る第１の実施の形態の動作を示すフローチャートである。
【００２５】
ユーザーは、入力装置１を用いて市町村名を音響到達エリア描画手段２１へ入力する（図２のステップＡ１）。音響到達エリア描画手段２１は、入力された市町村名を地図データベース３１へ入力し、地図データベース３１は、入力された市町村名をキーに登録されている地図の検索を開始する（ステップＡ２）。ここで地図が登録されていなければ、処理を続行することはできないので処理を終了する（ステップＡ３のノー）。入力された市町村名に該当する市町村地図の検索に成功した場合（ステップＡ３のイエス）は、出力装置４の画面に市町村地図を表示する（ステップＡ４）。次に、市町村名は屋外拡声子局情報データベース３２へ入力され、該当する屋外拡声子局の情報を検索し（ステップＡ５）音響到達エリア描画手段２１へ入力される。
【００２６】
音響到達エリア描画手段２１は、入力された屋外拡声子局情報の内、屋外拡声子局の位置、スピーカの数量、方向、出力ワット数及び音響到達エリアパターンを基に、既に画面に表示されている市町村の地図上に屋外拡声子局の位置を表すシンボルとスピーカの音響到達エリア図を階層的に重ねて表示する（ステップＡ６）。この後ユーザーは、音響到達エリア編集手段２２により、画面上に表示されている屋外拡声子局の情報または音響到達エリア図の変更を行うことができる（ステップＡ７）。変更することができる項目としては、例えば屋外拡声子局の位置に関する移動、削除、新設の操作、及びスピーカの数量、出力ワット数（音量）、方向（向き）に応じて決まる音響到達エリア図である。
【００２７】
変更作業の具体的な例としては、変更作業全てをマウスの操作による方法、あるいはキーボードより屋外拡声子局番号を入力して屋外拡声子局を選択し、屋外拡声子局の位置の移動やスピーカの方向の変更等をマウスで行う方法等がある。変更作業終了後、変更内容を保存（屋外拡声子局情報を更新）し（ステップＡ８）、必要ならば音響到達エリア図を出力装置４のプリンタへ出力する（ステップＡ９、Ａ１０）。
【００２８】
（第２の実施の形態）第２の実施の形態について図３を参照して詳細に説明する。図３は、本発明の防災行政無線設備屋外拡声子局用音響到達エリア模擬システムに係る第２の実施の形態を示すブロック図である。なお、図３において図１に対応するものは同一の参照数字または符号を付し、その説明を省略する。
【００２９】
図３を参照すると、遠隔地端末５とデータ処理装置２とがネットワーク１００により接続された形態である点で図１と相違している。なお以降の説明では、ネットワーク１００はインターネットを含むネットワークとする。
【００３０】
遠隔地端末５は、データ処理装置２が置かれている場所とは離れた所に設置され、ネットワーク１００を介しデータ処理装置２に接続された端末である。遠隔地端末５は、ネットワーク１００を介してデータ処理装置２（データ処理装置２には、音響到達エリア模擬プログラムが最初から格納されており、音響到達エリア描画手段２１と音響到達エリア編集手段２２とが、この音響到達エリア模擬プログラムの制御下で動作する。）へ接続されることにより、データ処理装置２を経由して記憶装置３のデータベース（地図データベース３１、屋外拡声子局情報データベース３２）の内容を参照及び変更することを可能とするものである。
【００３１】
次に、第２の実施の形態の動作を図４を参照して詳細に説明する。図４は、本発明の第２の実施の形態の動作を示すフローチャートである。遠隔地端末５のユーザーはネットワーク１００に接続後、防災行政無線設備の音響到達エリア模擬プログラム専用のホームページへアクセスする（図４のステップＢ１及びＢ２）。例えば、この専用のホームページは、自治体あるいは自治体から委託された団体によって開設され運用されるホームページである。次にユーザーであることを確認するログイン手続きを行う（ステップＢ３、Ｂ４）。ログインが完了し認められたユーザーであることを確認すると、データ処理装置２は、遠隔地端末５へ市町村名の入力を求める画面を送信する（ステップＢ５）。
【００３２】
以降の動作は、遠隔地端末５における操作、表示を除いて図２に示されるステップＡ１〜Ａ１０の第１の実施の形態の場合と同様なので、遠隔地端末５に係る部分を中心に、続いて説明する。
【００３３】
ユーザーは、屋外拡声子局が設置される市町村の名称を遠隔地端末５を用いて入力する（ステップＡ１’）。音響到達エリア描画手段２１は、入力された市町村名を地図データベース３１へ入力し、地図データベース３１は、入力された市町村名をキーに登録されている市町村の地図を検索する（ステップＡ２’）。ここで地図が登録されていなければ、処理を続行することはできないので処理を終了する（ステップＡ３’のノー）。入力された市町村名に該当する市町村地図の検索に成功した場合（ステップＡ３’のイエス）は、市町村地図を遠隔地端末５において表示する（ステップＡ４’）。次に、市町村名は屋外拡声子局情報データベース２へ入力され、該当する屋外拡声子局情報を検索し（ステップＡ５’）、音響到達エリア描画手段２１へ入力される。
【００３４】
音響到達エリア描画手段２１は、市町村の地図上に屋外拡声子局の位置を表すシンボルと音響到達エリア図を階層的に重ねて遠隔地端末５において表示する（ステップＡ６’）。この後ユーザーは、遠隔地端末５から音響到達エリア編集手段２２により、遠隔地端末５の画面上に表示されている屋外拡声子局の情報や音響到達エリア図の変更を行うことができる（ステップＡ７’）。遠隔地端末５から、変更による内容を保存（屋外拡声子局情報を更新）し（ステップＡ８’）、音響到達エリア図を遠隔地端末５において印刷する（ステップＡ９’、Ａ１０’）。作業終了後、ログアウト手続きを行って終了する（ステップＢ６）。
【００３５】
（第３の実施の形態）次に、本発明の第３の実施の形態について図５を参照して詳細に説明する。図５は、本発明の第３の実施の形態を示すブロック図である。なお、図５において図１に対応するものは同一の参照数字または符号を付し、その説明を省略する。入力装置１、データ処理装置２ａ、出力装置４が、記憶装置３と離間していることが、第１の実施の形態との相違点である。
【００３６】
遠隔地端末５ａに、入力装置１、データ処理装置２ａ、音響到達エリア描画手段２１、音響到達エリア編集手段２２、データベース接続確立手段２３、出力装置４を備え、ネットワーク１００を介して、アクセス処理装置８、記憶装置３を備える構成である。
【００３７】
データベース接続確立手段２３とアクセス処理装置８（ユーザー認証手段８１及び通信制御手段８２）は、ユーザーを認証し、記憶装置３と接続し、地図データベース３１、屋外拡声子局情報データベース３２を利用する機能を提供する。ユーザーを認証し、記憶装置３のデータベースに接続された後は、第１の実施の形態で説明したのと同様の動作を行うので、説明は省略する。作業終了後、接続を解除し、終了する。
【００３８】
（第４の実施の形態）次に、本発明の第４の実施の形態について図面を参照して詳細に説明する。図６は、本発明の第４の実施の形態を示すブロック図である。なお、図６において図１に対応するものは同一の参照数字または符号を付し、その説明を省略する。
【００３９】
図６を参照すると、第４の実施の形態は、音響到達エリア模擬プログラムを記録した記録媒体６を備える。この記録媒体６は磁気ディスク、半導体メモリその他の記録媒体であってよい。音響到達エリア模擬プログラムは、第１の実施の形態における音響到達エリア描画手段２１と音響到達エリア編集手段２２の動作を制御するプログラムである。
【００４０】
音響到達エリア模擬プログラムは、記録媒体６からデータ処理装置７に読み込まれ、データ処理装置７の動作を制御する。データ処理装置７は音響到達エリア模擬プログラムの制御により以下の処理、すなわち第１の実施の形態におけるデータ処理装置２による処理と同一の処理を実行する。
【００４１】
入力装置１より市町村名を入力すると、地図データベース３１において該当する市町村の地図を検索し、検索に成功すると該当する市町村地図を出力装置４に与える。次に屋外拡声子局情報データベース３２において、市町村名に該当する屋外拡声子局情報（屋外拡声子局の位置、スピーカの種類、数量、出力ワット数、方向（向き）、音響到達エリアパターン等）が検索され、既に出力装置４の画面に表示されている地図上に階層的に重ねて表示する。ここでユーザーは、屋外拡声子局の移動、削除、新設と音響到達エリアの変更作業を行うことができる。変更後の結果は、屋外拡声子局情報データベース３２に保存される。また、結果を印刷する場合は、出力装置４に備えたプリンタによって、印刷することができる。
【００４２】
【発明の効果】
第１の効果は、簡単な操作で屋外拡声子局の位置の変更に伴うスピーカの方向（向き）や音響到達エリア図が画面上で模擬できるので、考え得る場合における作業後の様子が地図上で一目瞭然となることである。この結果、予め最適な結果を予測できるので、現地での調査にかかる手間が省け、検討作業にかかる時間の大幅な削減を図ることができる。
【００４３】
第２の効果は、検討結果は全て画面上に表現されるため、紙の地図上で検討作業を行う場合に生じる音響到達エリア図の書き直し作業が無くなることである。この結果、作業者の負担を大幅に軽減でき、また、常に情報は最新の状態に保たれる。
【００４４】
第３の効果は、防災行政無線設置者等の第三者へ音響到達エリアを決定する過程を見せることができることにある。この結果、第三者、例えば防災行政無線設置者に対し、設置許可等の理解が得やすくなり迅速な対応が図れる。
