Connected to the control unit 4 are a display 9, a printer 10, a keyboard 11, and the like for setting and inputting broadcast signals. The control unit 4 transmits an audio signal from the microphone 13 or the BGM source 33 to the notification broadcast transmission unit 12, and the audio signal is FM modulated by the notification broadcast transmission unit 12. An output from the notification broadcast transmission unit 12 is given to the transmission line 1 via the head end 2. Here, the control unit 4 can also transmit a broadcast signal from an audio device such as a tape recorder in addition to an audio signal from the microphone 13 or the BGM source 33. Alternatively, character data input from the keyboard 11 and displayed on the display 9 can be encoded and transmitted as a broadcast signal. Furthermore, image data based on video input through the display 9 can be appropriately encoded and transmitted as a broadcast signal.

図２は制御部４から送信される告知放送のフレーム構成を示したものである。制御部４から送信される告知放送は、告知放送受信機１６のスピーカ２５にて放送される音声情報と、告知放送受信機１６が告知放送の音声情報を制御するための制御情報とから構成される。告知放送の制御情報には告知放送の対象となるアドレスデータと、告知放送の種類を示すデータと、告知放送の音声情報の録音可否を示す録音可否データと、放送開始／終了データが含まれる。   FIG. 2 shows the frame structure of the notification broadcast transmitted from the control unit 4. The notification broadcast transmitted from the control unit 4 is composed of audio information broadcast by the speaker 25 of the notification broadcast receiver 16 and control information for the notification broadcast receiver 16 to control the audio information of the notification broadcast. The The control information of the notification broadcast includes address data that is a target of the notification broadcast, data indicating the type of the notification broadcast, recording availability data indicating whether or not the sound information of the notification broadcast can be recorded, and broadcast start / end data.

制御部４からは、最初に放送開始の制御情報を送信し、続いて音声情報、最後に放送終了の制御情報を送信する。制御情報の設定はキーボード１１の操作により行われ、告知放送の対象となる端末のアドレス指定と、送信する告知放送が緊急告知放送であるか一般告知放送であるかの放送種別の設定と、送信する告知放送を告知放送受信機１６において録音させるかどうかの録音設定を行う。   From the control unit 4, broadcast start control information is transmitted first, followed by audio information, and finally broadcast end control information. The control information is set by operating the keyboard 11, the address of the terminal that is the target of the notification broadcast, the broadcast type setting of whether the notification broadcast to be transmitted is an emergency notification broadcast, or a general notification broadcast, and transmission Recording setting is performed to determine whether or not the notification broadcast receiver 16 records the notification broadcast.

アドレス設定には、全加入端末を放送対象とする全端末一斉指定と、サービス地域やマンション等のグループ単位でブロック分けしたグループ指定と、個別に加入端末を指定する個別指定とがある。グループ指定の場合には、キーボード１１によりグループアドレスを入力することにより行う。そして、放送種別においては緊急告知放送のほうが一般告知放送よりも重要度が高く、対象端末指定においては重要度の高い順に全端末一斉指定、グループ指定、個別指定であることから、放送種別及び対象端末の設定により告知放送をその重要度で分類することができる。すなわち、告知放送の制御情報には告知放送の重要度を示す種別データが含まれる。  The address setting includes simultaneous designation of all terminals for broadcasting to all the subscribed terminals, group designation divided into blocks such as service areas and apartments, and individual designation for individually designating the subscribed terminals. In the case of group designation, it is performed by inputting a group address with the keyboard 11. And in the broadcast type, the emergency notification broadcast is more important than the general announcement broadcast, and in the target terminal designation, all terminals are designated simultaneously, group designation, individual designation in order of importance, so the broadcast type and target Notification broadcasts can be classified by their importance according to terminal settings. That is, the control information of the notification broadcast includes type data indicating the importance of the notification broadcast.

録音設定は上述のアドレス指定された告知放送受信機１６に対して告知放送を録音するか否かをキーボード１１により録音可否データとして入力することで行う。録音を許可する場合には、当該告知放送をどれだけの期間保存させるか設定することができる。保存期間設定は、例えば保存日数等をキーボード１１の操作により保存期間データとして入力することにより行う。また、保存期間を設定しないことで録音した告知放送を消去しないようにすることもできる。   The recording setting is performed by inputting whether or not to record the notification broadcast to the above-mentioned addressed notification broadcast receiver 16 by using the keyboard 11 as recording availability data. When recording is permitted, it is possible to set how long the notification broadcast is stored. For example, the storage period is set by inputting the storage days as storage period data by operating the keyboard 11. It is also possible not to delete the recorded announcement broadcast by not setting the retention period.

そして、告知放送の開始もしくは終了時刻をカレンダー回路３７から読み出し、告知放送の音声情報の最初もしくは最後に音声にて送信する。放送時刻は音声ではなく、データとして送ってもよい。なお、このカレンダー回路３７は告知放送受信機１６側で持っていてもよい。   Then, the start or end time of the notification broadcast is read from the calendar circuit 37 and transmitted by voice at the beginning or end of the voice information of the notification broadcast. The broadcast time may be sent as data instead of voice. The calendar circuit 37 may be provided on the notification broadcast receiver 16 side.

図３は告知放送の送信処理について示したフローチャートである。告知放送の送信処理は、図３のフローチャートに従って行われる。この図に示すように、まず制御部４はキーボード１１の操作で、もしくは予め設定しておいた告知放送の送信時刻がきて告知放送モードとされたか否かを判断する（ＴＳ１）。そしてキーボード１１入力に従って、告知放送を緊急告知放送であるか一般告知放送であるかの種別設定を行う（ＴＳ２）。次に、告知放送の対象となる告知放送受信機１６のアドレス指定を行う（ＴＳ３）。この放送対象となる端末アドレスの設定は、キーボード１１により入力することで行う。   FIG. 3 is a flowchart showing notification broadcast transmission processing. The notification broadcast transmission process is performed according to the flowchart of FIG. As shown in this figure, first, the control unit 4 determines whether or not the notification broadcast mode is set by operating the keyboard 11 or when a preset notification broadcast transmission time comes (TS1). Then, according to the keyboard 11 input, the type of notification broadcast is set to be an emergency notification broadcast or a general notification broadcast (TS2). Next, the address of the notification broadcast receiver 16 that is the target of the notification broadcast is specified (TS3). The terminal address to be broadcast is set by inputting from the keyboard 11.

次にＴＳ３において指定された告知放送受信機１６に対して告知放送を録音させるか否かの設定を行う（ＴＳ４）。録音設定は録音許可または録音禁止のどちらかを選択することにより行われる。ここで、録音禁止を選択入力した場合には、放送開始データの設定は終了し、ＴＳ７の音声情報設定を行う。   Next, it is set whether or not the notification broadcast receiver 16 designated in TS3 is to record the notification broadcast (TS4). The recording setting is performed by selecting either recording permission or recording prohibition. Here, when recording prohibition is selected and input, the setting of the broadcast start data ends, and the audio information setting of TS7 is performed.

録音許可を選択入力した場合には告知放送の保存期間設定を行い（ＴＳ５）、放送開始データの設定は終了する。放送開始データの設定が終了すると、続いてマイク１３やＢＧＭ源３３により音声情報の入力を行う（ＴＳ６）。次に、放送対象となる端末アドレスとストップ信号とからなる放送終了データを設定し（ＴＳ７）、告知放送の設定が終了する。告知放送の設定が終了すると告知放送受信機１６に送信され（ＴＳ８）、センタ装置３側の送信処理が終了する。   When the recording permission is selected and input, the notification broadcast storage period is set (TS5), and the setting of the broadcast start data is completed. When the setting of the broadcast start data is completed, audio information is subsequently input through the microphone 13 and the BGM source 33 (TS6). Next, broadcast end data consisting of a terminal address to be broadcast and a stop signal is set (TS7), and notification broadcast setting is completed. When the notification broadcast setting is completed, it is transmitted to the notification broadcast receiver 16 (TS8), and the transmission processing on the center device 3 side is completed.

本実施形態では告知放送受信機１６に送信する告知放送の制御情報に予め録音可否を設定することとしたので、放送者が放送する内容を考慮して告知放送を各告知放送受信機１６に録音させるかどうかを選択することができる。すなわち、重要性を有しないと思われる告知放送には録音禁止を選択設定することにより告知放送受信機１６に既に録音されている告知放送が消去されることはない。また、アドレス設定をグループ指定した場合には、そのグループ毎に録音可否を設定することができるので、グループの地域や設置場所の種類に応じてきめ細かい設定ができ、また設定操作が容易である。なお、キーボート１１等を使ってグループ毎に録音の要否を予め決定しておけば、告知放送を送信する際に、グループアドレスを選択すると自動的に録音可否が設定されるので、設定操作が容易となる。さらに告知放送の種別毎に予め録音要否の初期選択値を設定しておいてもよい。   In this embodiment, since recording permission is set in advance in the control information of the notification broadcast transmitted to the notification broadcast receiver 16, the notification broadcast is recorded in each notification broadcast receiver 16 in consideration of the content broadcast by the broadcaster. You can choose whether or not That is, by selecting and setting prohibition of recording for a notification broadcast that does not seem to be important, a notification broadcast that has already been recorded in the notification broadcast receiver 16 is not erased. In addition, when the address setting is designated as a group, whether recording is possible or not can be set for each group, so that detailed settings can be made according to the area of the group and the type of installation place, and the setting operation is easy. If the necessity of recording for each group is determined in advance using the keyboard 11 or the like, the recording operation is automatically set when the group address is selected when the notification broadcast is transmitted. It becomes easy. Further, an initial selection value for necessity of recording may be set in advance for each type of notification broadcast.

また、制御部４は一般電話回路網５０にも接続されており、一般家庭電話、携帯電話等の電話機５１から放送日時、告知内容、放送グループ等を事前に登録することによって、指定した時間に自動的に告知放送を行うことができる。   The control unit 4 is also connected to a general telephone network 50, and at a specified time by registering the broadcast date / time, notification contents, broadcast group, etc. in advance from a telephone 51 such as a general home phone or a mobile phone. Announcement broadcasting can be performed automatically.

次に伝送線路１の端末に設けられる告知放送受信機１６について説明する。図４に告知放送受信機１６のブロック図を示す。この図に示すように、告知放送受信機１６はセンタ装置３から送信された告知放送を受信復調する復調部２２と、この復調した告知放送に含まれる制御情報に基づき制御するマイコン１７が設けられる。マイコン１７は自端末の個別アドレスを記憶した個別記憶部１８と、自己の属するグループのグループアドレスを記憶したグループ記憶部１９とを有している。そして、復調部２２で復調された音声情報の出力手段として、音声情報を増幅する音声アンプ２４と、スピーカ２５を有し、音声アンプ２４の前段にはスピーカ２５からの音量を調整するための音量調整部２８が備えられる。   Next, the notification broadcast receiver 16 provided at the terminal of the transmission line 1 will be described. FIG. 4 shows a block diagram of the notification broadcast receiver 16. As shown in this figure, the notification broadcast receiver 16 is provided with a demodulator 22 for receiving and demodulating the notification broadcast transmitted from the center apparatus 3, and a microcomputer 17 for controlling based on the control information included in the demodulated notification broadcast. . The microcomputer 17 includes an individual storage unit 18 that stores an individual address of the terminal itself, and a group storage unit 19 that stores a group address of a group to which the microcomputer 17 belongs. The output unit of the audio information demodulated by the demodulator 22 includes an audio amplifier 24 that amplifies the audio information and a speaker 25, and a volume for adjusting the volume from the speaker 25 in the previous stage of the audio amplifier 24. An adjustment unit 28 is provided.

また、告知放送受信機１６は、受信した告知放送の音声情報を記憶する音声メモリ３１と、音声メモリ３１に告知放送を記憶させる録音手段３０とを有している。録音手段３０は復調部２２から出力される告知放送の音声情報を録音データに変換して音声メモリ３１に記憶させる録音処理を行う。   Further, the notification broadcast receiver 16 has an audio memory 31 for storing audio information of the received notification broadcast, and a recording unit 30 for storing the notification broadcast in the audio memory 31. The recording means 30 performs a recording process in which the audio information of the announcement broadcast output from the demodulator 22 is converted into recorded data and stored in the audio memory 31.

センタ装置３からの告知放送は全加入端末に送信される。そして、告知放送受信機１６のマイコン１７は告知放送の制御情報に指定された端末アドレスが個別記憶部１８又はグループ記憶部１９に記憶されている個別アドレス又はグループアドレスと一致する場合に自端末が放送対象であると判断する。すなわち、マイコン１７は受信した告知放送の制御情報から自端末が放送対象として指定されているか否かを判別し、指定されていれば、出力手段に音声情報出力の指令信号を出力すると共に録音手段３０に録音動作の指令信号を出力する。   The announcement broadcast from the center device 3 is transmitted to all the subscriber terminals. Then, the microcomputer 17 of the notification broadcast receiver 16 determines that the terminal of the terminal when the terminal address specified in the control information of the notification broadcast matches the individual address or group address stored in the individual storage unit 18 or the group storage unit 19. Judged to be broadcast. That is, the microcomputer 17 determines whether or not the terminal is designated as a broadcast target from the control information of the received notification broadcast, and if so, outputs a voice information output command signal to the output means and the recording means. A recording operation command signal is output to 30.

また、復調部２２にて復調された制御情報は、マイコン１７に設けられたメモリ３９に記憶され、音声メモリ３１の音声情報と対応が保持され、告知放送の再生、録音、消去に使用される。   The control information demodulated by the demodulator 22 is stored in a memory 39 provided in the microcomputer 17, and the correspondence with the audio information in the audio memory 31 is maintained, and is used for reproducing, recording, and erasing notification broadcasts. .

図５は告知放送受信機における告知放送処理を示したフローチャートである。この図に示すようにマイコン１７は、まず受信した告知放送に自端末が放送対象として指定されているか否かを判断する（ＲＳ１）。そして、指定されている場合には告知放送の制御情報に含まれる録音可否データから告知放送の録音可否を判別する（ＲＳ２）。そして、録音可否データが録音許可を示す場合には音声メモリ３１に空きがあるか否か判別し（ＲＳ３）、音声メモリ３１に空きがある場合には、出力手段及び録音手段３０に制御信号を出力し、音声情報をスピーカ２５にて放送出力すると共に音声メモリ３１に音声情報を録音し（ＲＳ４）、空きがない場合には放送出力を行うと共に音声メモリ３１に音声情報を上書き録音する（ＲＳ５）。ＲＳ２において録音可否データが録音禁止を示す場合には放送出力のみを行い（ＲＳ６）、音声メモリ３１には録音しない。   FIG. 5 is a flowchart showing notification broadcast processing in the notification broadcast receiver. As shown in this figure, the microcomputer 17 first determines whether or not its own terminal is designated as a broadcast target in the received notification broadcast (RS1). If it is designated, whether or not the notification broadcast can be recorded is determined from the recordability data included in the control information of the notification broadcast (RS2). When the recording permission / inhibition data indicates that recording is permitted, it is determined whether or not the voice memory 31 is empty (RS3). If the voice memory 31 is empty, a control signal is sent to the output means and the recording means 30. Output and broadcast the audio information through the speaker 25 and record the audio information in the audio memory 31 (RS4). If there is no space, the broadcast information is output and the audio information is overwritten and recorded in the audio memory 31 (RS5). ). When the recording permission / prohibition data in RS2 indicates that recording is prohibited, only the broadcast output is performed (RS6), and the sound memory 31 is not recorded.

すなわち、マイコン１７は告知放送の制御情報に含まれる録音可否データが録音許可を示す場合には受信した音声情報を放送出力すると共に音声メモリ３１に録音又は上書き録音し、録音許可データが録音禁止を示す場合には音声情報の放送出力のみを行い音声メモリ３１には録音しない。そして、マイコン１７は録音された告知放送の音声情報を保存期間データにより設定された期間の経過時に消去する。   That is, the microcomputer 17 broadcasts the received audio information and records or overwrites it in the audio memory 31 when the recording availability data included in the control information of the announcement broadcast indicates that recording is permitted, and the recording permission data prohibits recording. In the case shown, only the audio information is broadcasted and not recorded in the audio memory 31. Then, the microcomputer 17 erases the recorded sound information of the notification broadcast when the period set by the retention period data has elapsed.

またＲＳ５の動作において、告知放送の制御情報に含まれる種別データを比較し、新規の告知放送よりも重要度が低い告知放送が録音されている場合には、その告知放送を消去して新規の告知放送を録音し、新規の告知放送よりも重要度が低い告知放送が音声メモリ３１に録音されていなければ新規の告知放送を録音しないようにしてもよい。これにより、録音可否データが録音許可を示す場合であっても、既に音声メモリ３１に録音されているより重要な告知放送が消去されることを防止することができる。   Also, in the operation of RS5, the type data included in the control information of the notification broadcast is compared, and if a notification broadcast having a lower importance than the new notification broadcast is recorded, the notification broadcast is deleted and a new one is recorded. The notification broadcast may be recorded, and the new announcement broadcast may not be recorded unless the announcement broadcast having a lower importance than the new announcement broadcast is recorded in the audio memory 31. As a result, even if the recording permission / inhibition data indicates that recording is permitted, it is possible to prevent the more important announcement broadcast already recorded in the audio memory 31 from being deleted.

また、マイコン１７には告知放送の出力を切り替える音声切替部３６が接続されている。音声切替部３６はマイコン１７により制御されて、復調部２２で受信した告知放送の出力と音声メモリ３１に記憶されている告知放送の再生出力とを切り替えることができる。   The microcomputer 17 is connected to an audio switching unit 36 that switches the output of the notification broadcast. The sound switching unit 36 is controlled by the microcomputer 17 and can switch between the notification broadcast output received by the demodulation unit 22 and the reproduction output of the notification broadcast stored in the sound memory 31.

また、マイコン１７には音声メモリ３１における告知放送の録音状態を知らせるための告知ランプが接続されている。告知ランプは緊急告知放送用の緊急告知ランプ３５と一般告知放送用の一般告知ランプ３４が備えられている。また、マイコン１７には、音声メモリ３１に記憶された告知放送の音声情報を再生出力させるための再生スイッチ３８が接続されている。  The microcomputer 17 is connected to a notification lamp for notifying the recording state of the notification broadcast in the audio memory 31. The notification lamp includes an emergency notification lamp 35 for emergency notification broadcasting and a general notification lamp 34 for general notification broadcasting. The microcomputer 17 is connected to a reproduction switch 38 for reproducing and outputting the sound information of the notification broadcast stored in the sound memory 31.

一般告知ランプ３４もしくは緊急告知ランプ３５は告知放送の録音中は点灯し、告知放送の録音が終了すると点滅状態に切り替えられる。そして、録音された告知放送を再生するための再生スイッチ３８が押された場合に消灯する。したがって、一般告知ランプ３４もしくは緊急告知ランプ３５は、告知放送の受信録音が再生スイッチ３８の操作で確認されない限り点滅状態を保つため、端末利用者が留守の間に告知放送があった場合でも、告知放送があったことを容易に知ることができる。   The general notification lamp 34 or the emergency notification lamp 35 is turned on during recording of the notification broadcast, and is switched to a blinking state when the recording of the notification broadcast is completed. When the playback switch 38 for playing back the recorded notification broadcast is pressed, the light is turned off. Therefore, since the general notification lamp 34 or the emergency notification lamp 35 keeps blinking unless the received recording of the notification broadcast is confirmed by the operation of the playback switch 38, even when the terminal user is in the absence of the notification broadcast, You can easily know that there was an announcement broadcast.

録音されている告知放送を再生させる再生スイッチ３８が押されると、再生手段であるマイコン１７は音声メモリ３１に記憶された告知放送をその重要度の高い順に選択し、スピーカ２５から再生する。すなわち端末利用者は、重要な緊急告知放送等から聞くことができるので、未確認の告知放送を確認するための時間を長くとれない場合等に便利である。   When the reproduction switch 38 for reproducing the recorded announcement broadcast is pressed, the microcomputer 17 as the reproduction means selects the announcement broadcasts stored in the audio memory 31 in the descending order of importance and reproduces them from the speaker 25. That is, the terminal user can listen to important emergency notification broadcasts and the like, which is convenient when it is not possible to take a long time to confirm unconfirmed notification broadcasts.

以上、本発明の実施形態について説明したが、本発明の適用はこれら実施形態には限られず、その技術的思想の範囲内において様々に適用されうるものである。例えば、告知放送の送信処理は、まず放送開始データを送信して告知放送受信機１６を音声情報の受信及び出力が可能な状態とし、マイク１３やＢＧＭ源３３により直接告知放送を行い、告知放送の終了時に放送終了データを送信することによって告知放送を終了させるようにしてもよい。   As mentioned above, although embodiment of this invention was described, application of this invention is not restricted to these embodiment, It can apply variously within the range of the technical idea. For example, in the notification broadcast transmission process, first, broadcast start data is transmitted so that the notification broadcast receiver 16 can receive and output audio information, and the microphone 13 and the BGM source 33 directly perform the notification broadcast. Notification broadcast may be terminated by transmitting broadcast end data at the end of.
