Description

【0001】
【発明の属する技術分野】
本発明は、市町村単位に設置される市町村防災行政無線システムにおける放送方式に関するものである。
【0002】
【従来の技術】
図2は従来の市町村防災行政無線システム親局の一例を示すブロック図である。図2において、1はマイク等から入力された音声信号を送出する音声送出部、4は変調された音声信号、または文字データを無線回線に送出する送信部、5はアンテナ、6はFAX、コンピュータ等から入力された文字データを送出する文字データ送出部、7は音声信号と文字データの出力を切り替える切替部、8は送出する音声信号または文字データを無線回線に送出できるようにする変調部を示す。
【0003】
従来の方式では、健常者と難聴者に各種情報を放送する場合、音声送出または文字データ送出のいずれか一方の放送を初めに行い、その放送が終了した後、他方の放送を行う必要があったため、健常者と難聴者に対して同時に放送内容を伝えることが不可能であった。
【0004】
【発明が解決しようとする課題】
前述の従来の方式では、音声放送と文字データ放送を同時に行うことが不可能であるという欠点がある。この欠点を解決し、音声放送を行うだけで音声放送と文字データ放送を同時に放送可能とすることを目的とする。
【0005】
【課題を解決するための手段】
本発明は上記の目的を達成するため、音声送出部からの音声放送を文字データに変換して、音声放送と文字データ放送を異なるチャネルにて同時に放送可能とするため、音声→文字データ変換部、音声データ合成変調部を追加する。
【0006】
その結果、音声放送を行うだけで、音声送出部からの音声放送を文字データに変換して、音声放送と文字データ放送を異なるチャネルにて同時に放送することができるようになる。
【0007】
【発明の実施の形態】
以下、本発明の一実施例を図1により説明する。1はマイク等から入力された音声信号を送出する音声送出部、2は音声送出部から出力された音声信号を文字データに変換する音声→文字データ変換部、3は音声送出部1から出力された音声放送内容と音声→文字データ変換部2から出力された文字データ放送内容を異なるチャネルにて変調して同時に出力する音声データ合成変調部、4は変調されたデータを無線回線に送出する送信部、5はアンテナを示す。
【0008】
音声送出部1はマイク等から入力された音声信号を音声放送内容として、音声→文字データ変換部2と音声文字データ合成変調部3に出力する。音声→文字データ変換部2は、入力された音声放送内容を文字データに変換し、音声文字データ合成変調部3に文字データ放送内容を出力する。音声文字データ合成変調部3は、入力された音声放送内容と文字データ放送内容を異なるチャネルにて同時に変調を行って、送出部4に出力し、送出部4からアンテナ5を介して無線回線に出力され、音声放送と文字データ放送が同時に行うことが可能となる。
【0009】
【発明の効果】
本発明により、音声放送を行うだけで音声放送と文字データ放送を同時に放送可能となる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a broadcasting system in a municipal emergency management radio system installed in municipal units.
[0002]
[Prior art]
FIG. 2 is a block diagram showing an example of a conventional municipal disaster prevention administrative radio system master station. In FIG. 2, reference numeral 1 denotes an audio transmission unit for transmitting an audio signal input from a microphone or the like, 4 denotes a transmission unit for transmitting a modulated audio signal or character data to a wireless line, 5 denotes an antenna, 6 denotes a FAX, and a computer. A character data transmitting unit for transmitting character data input from the like, a switching unit 7 for switching between output of a voice signal and character data, and a modulation unit 8 for transmitting a voice signal or character data to be transmitted to a wireless line. Show.
[0003]
In the conventional method, when broadcasting various information to a healthy person and a hearing-impaired person, it is necessary to perform broadcasting of either one of voice transmission and character data first, and after the broadcasting ends, perform the other broadcasting. Therefore, it was impossible to simultaneously transmit the broadcast contents to healthy persons and hearing-impaired persons.
[0004]
[Problems to be solved by the invention]
The above-mentioned conventional method has a drawback that it is impossible to simultaneously perform audio broadcasting and text data broadcasting. It is an object of the present invention to solve this drawback and to enable simultaneous broadcasting of audio broadcasting and text data broadcasting only by performing audio broadcasting.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the present invention converts an audio broadcast from an audio transmission unit into character data, and enables an audio broadcast and a character data broadcast to be simultaneously broadcast on different channels. , A voice data synthesis modulator is added.
[0006]
As a result, only by performing the audio broadcasting, the audio broadcasting from the audio transmitting unit can be converted into character data, and the audio broadcasting and the character data broadcasting can be simultaneously broadcast on different channels.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIG. Reference numeral 1 denotes a voice transmitting unit for transmitting a voice signal input from a microphone or the like, 2 denotes a voice → character data converting unit for converting a voice signal output from the voice transmitting unit into character data, and 3 denotes a voice output from the voice transmitting unit 1. The audio data synthesizing and modulating section which modulates the audio broadcast contents and the character data broadcast contents output from the audio-> character data conversion section 2 on different channels and simultaneously outputs the modulated data, and 4 transmits the modulated data to the wireless line. Reference numeral 5 denotes an antenna.
[0008]
The audio transmission unit 1 outputs an audio signal input from a microphone or the like as audio broadcast content to the audio-to-character data conversion unit 2 and the audio-character data synthesis / modulation unit 3. The voice-to-text data conversion unit 2 converts the input voice broadcast content into text data and outputs the text data broadcast content to the voice text data synthesis and modulation unit 3. The voice / text data synthesizing / modulating unit 3 simultaneously modulates the input voice broadcast content and text data broadcast content on different channels, outputs the modulated content to the transmission unit 4, and transmits the data to the wireless line via the antenna 5 from the transmission unit 4. The audio broadcast and the text data broadcast can be performed at the same time.
[0009]
【The invention's effect】
According to the present invention, audio broadcasting and text data broadcasting can be simultaneously broadcasted only by performing audio broadcasting.
