The best mode for carrying out the invention will be described below with reference to the drawings.
FIG. 1 shows functional blocks of the indoor parent device 001 and the outdoor child device 002 of the present invention.
The indoor base unit 001 includes an interphone control unit 01 that controls the indoor base unit 001 and the outdoor unit 002 as a whole, an emergency response unit 02 that determines that it is an emergency and issues an instruction to the related unit, and an interphone control unit A specific voice detection sensitivity adjustment unit 03 that adjusts the detection sensitivity of the specific voice detection unit 04 according to an instruction 01, a specific voice detection unit 04 that detects a specific voice registered in advance, and a specific voice pattern registration in which the specific voice is registered in advance Unit 05, microphone 06 which is an audio input unit for capturing room audio, speaker 07 which outputs audio, notification unit 08 which notifies an emergency message to notification destination 11 in case of emergency, emergency emergency button 09, lock of door 12 key The key opening and closing unit 10 that monitors and controls unlocking, and the emergency message registration unit 13 that registers in advance an emergency message that is output in an emergency, are included as components.
The outdoor child device 002 amplifies the sound on the control unit 14 for controlling the entire child device, the interphone call unit 15 that accommodates the interphone microphone 20 and the call button 21, the character display unit 16 that displays characters on the monitor 18, and the speaker 19. An output loudspeaker 17 is provided as a component.
室内親機００１は玄関等のドア１２の錠が施錠から開錠に状態変化するのを鍵開閉部１０で常時監視している。住人が外出先から帰宅した時、ドア１２の錠を施錠から開錠に変化させると、これを鍵開閉部１０が検知し、インターホン制御部０１に信号『開錠』を送信する。 The indoor base unit 001 always monitors the key opening / closing part 10 for the state of the lock of the door 12 such as the entrance to change from locked to unlocked. When the resident returns home from the outside, if the lock of the door 12 is changed from locked to unlocked, the key opening / closing unit 10 detects this and transmits a signal “unlocked” to the intercom control unit 01.
インターホン制御部０１は、信号『開錠』を受信すると、特定音声検知感度調整部０３へ信号『感度上昇』を送信し、特定音声検知感度調整部０３は、‘感度高’を記憶保持する。この‘感度高’の状態は、インターホン制御部０１から信号『タイムアウト』を受信するまで継続し、それ以降は‘感度標準’の状態が記憶保持される。この継続時間は、インターホン制御部０１のタイマでパラメータ設定可能である。 When the intercom control unit 01 receives the signal “unlocked”, the intercom control unit 01 transmits the signal “sensitivity increase” to the specific voice detection sensitivity adjustment unit 03, and the specific voice detection sensitivity adjustment unit 03 stores and holds “high sensitivity”. This “high sensitivity” state continues until the signal “timeout” is received from the intercom control unit 01, and after that, the “sensitivity standard” state is stored and held. This duration can be parameter set by the timer of the intercom control unit 01.
特定音声検知部０４は音声入力部マイク０６から送られてくる室内で発生した音声を常時監視しているが、特定音声検知感度調整部０３の状態が‘感度高’に設定されている間は、室内音声を監視する検知レベルを通常より低くして監視する。これによって、ドア開錠直後の一定時間、特定音声検知部０４は感度が敏感になり、通常より低いレベルの音声を検知可能である。逆に一定時間経過後は、音声の検知レベルが通常に戻され、それまでより高くなるので、感度が鈍くなり、日常会話の類似音声によっては、誤動作しないようになる。 The specific sound detection unit 04 constantly monitors the sound generated in the room sent from the sound input unit microphone 06, while the state of the specific sound detection sensitivity adjustment unit 03 is set to “high sensitivity”. The detection level for monitoring room sound is set lower than usual. As a result, the specific voice detecting unit 04 becomes sensitive for a certain period of time immediately after the door is unlocked, and can detect a voice of a level lower than normal. On the contrary, after a certain period of time, the sound detection level is returned to the normal level and becomes higher than before, so the sensitivity becomes dull, and malfunction does not occur depending on the similar sound of daily conversation.
特定音声パターン登録部０５には、予め住人の悲鳴、大声や日常生活であまり聞くことのない騒音、発砲音等を登録しておく。 In the specific voice pattern registration unit 05, a resident's scream, loud voice, noise that is not often heard in daily life, a firing sound, and the like are registered in advance.
外出中に不審人物が室内に侵入し、その後住人が帰宅して、ドアの鍵を開錠した直後の一定時間内は上記したように特定音声検知感度調整部０３は‘感度高’に設定されるので、それを受けて特定音声検知部０４の音声検知レベルは、通常より低めに設定される。この通常より低めの検知レベルを超えるレベルの住人の悲鳴、大声と思われる音声を特定音声検知部０４で認識すると、特定音声検知部０４は認識した音声と特定音声パターン登録部０５に登録されている音声データとの照合を行なう。照合結果、両音声が
一致した場合、特定音声検知部０４から緊急対応部０２へ信号『特定音声検知』が送信される。
As described above, the specific voice detection sensitivity adjustment unit 03 is set to “high sensitivity” for a certain period of time immediately after the suspicious person enters the room while going out and the resident returns home and unlocks the door lock. Therefore, the voice detection level of the specific voice detection unit 04 is set lower than usual in response to this. When the specific voice detection unit 04 recognizes a scream or loud voice of a resident who exceeds a detection level lower than the normal level, the specific voice detection unit 04 registers the recognized voice and the specific voice pattern registration unit 05 with the recognized voice. The voice data is compared. If the two voices match as a result of the collation, the signal “specific voice detection” is transmitted from the specific voice detection unit 04 to the emergency response unit 02.
緊急対応部０２は、信号『特定音声検知』を受信すると、異常事態の発生と判断し、インターホン制御部０１と通知部０８へ信号『異常事態発生』を送信する。 Upon receiving the signal “specific voice detection”, the emergency response unit 02 determines that an abnormal situation has occurred, and transmits the signal “abnormal situation occurrence” to the intercom control unit 01 and the notification unit 08.
インターホン制御部０１は信号『異常事態発生』を受信すると、緊急メッセージ登録部１３から予め登録された緊急メッセージの２種のデータを読み出し、それに信号『異常事態発生』を併せて、緊急対応部０２及び室外子機００２の制御部１４へ送信する。 When the intercom control unit 01 receives the signal “occurrence of abnormal situation”, the emergency message registration unit 13 reads two types of data of the emergency message registered in advance from the emergency message registration unit 13, and combines the signal “abnormal situation occurrence” with the emergency response unit 02. And transmitted to the control unit 14 of the outdoor unit 002.
緊急メッセージ登録部１３には、緊急メッセージとして、例えば「室内で緊急事態が起きました。警察へ通報してください」に相当する音声データと、文字データの２種のデータが予め登録されている。この緊急メッセージは、詳細説明は省略するが、住人がマイク０６を用いて音声情報として、緊急メッセージ登録部に予め登録することができる。 In the emergency message registration unit 13, two types of data are registered in advance as emergency messages, for example, voice data corresponding to “an emergency has occurred in the room. Please notify the police” and character data. . Although detailed explanation is omitted, this urgent message can be registered in advance in the emergency message registration unit as voice information by the resident using the microphone 06.
また、インターホン制御部０１は、同時に鍵開閉部１０へも信号『異常事態発生』を送信する。鍵開閉部１０は、信号『異常事態発生』を受信すると、リモート機能でドア１２の鍵を開錠し、住人が素早く脱出できるように備える。 In addition, the intercom control unit 01 transmits a signal “abnormal situation occurrence” to the key opening / closing unit 10 at the same time. When the key opening / closing unit 10 receives the signal “occurrence of an abnormal situation”, the key opening / closing part 10 is unlocked by a remote function so that the resident can quickly escape.
緊急対応部０２は、受信した緊急メッセージ・データと信号『異常事態発生』を通知部０８に転送する。通知部０８には、予め緊急メッセージの連絡先やセキュリティ会社等の通知先１１が携帯電話や固定電話の電話番号として登録されている。そこで通知部０８は、信号『異常事態発生』を受信すると予め登録されている通知先１１の電話番号に自動発信し、受信した緊急メッセージ・データと信号『異常事態発生』を送付する。 The emergency response unit 02 transfers the received emergency message data and signal “abnormal situation occurrence” to the notification unit 08. In the notification unit 08, a contact address of an emergency message and a notification destination 11 such as a security company are registered in advance as a telephone number of a mobile phone or a fixed phone. Accordingly, when the notification unit 08 receives the signal “abnormal event occurrence”, the notification unit 08 automatically transmits to the telephone number of the notification destination 11 registered in advance, and sends the received emergency message data and the signal “abnormal event occurrence”.
室外子機００２の制御部１４は、緊急メッセージ・データと信号『異常事態発生』を受信すると受信した緊急メッセージ・データの文字データを文字表示部１６へ転送し、文字表示部１６では文字データを解析し、表示すべき文字データをモニタ１８へ送り、モニタ１８に表示する。また、受信した緊急メッセージ・データの音声データを拡声通知部１７へ送信し、拡声通知部１７では音声データを解析して、音声再生すべき音声データをスピーカ１９へ送り、スピーカ１９から音声出力する。 When the control unit 14 of the outdoor unit 002 receives the emergency message data and the signal “abnormal condition occurrence”, the control unit 14 transfers the received emergency message data character data to the character display unit 16, and the character display unit 16 receives the character data. The character data to be analyzed and displayed is sent to the monitor 18 and displayed on the monitor 18. Also, the voice data of the received emergency message / data is transmitted to the loudspeaker notification unit 17, which analyzes the voice data, sends the voice data to be played back to the speaker 19, and outputs the voice from the speaker 19. .
このようにして、本発明では、室内で発生した音声を監視することによって、異常状事態発生を検知し、外部にいる人に対して、室内での異常事態発生を知らせることができる。 In this way, in the present invention, the occurrence of an abnormal situation can be detected by monitoring the sound generated in the room, and the occurrence of the abnormal situation in the room can be notified to an outside person.
異常事態を解除するには、非常ボタンを長押しする。非常ボタンを長押しすると、緊急対応部０２は、異常事態解除を認識し、緊急対応部１２からインターホン制御部０１及び通知部０８へ信号『異常事態解除』を通知する。 To cancel the abnormal situation, press and hold the emergency button. When the emergency button is pressed for a long time, the emergency response unit 02 recognizes the cancellation of the abnormal situation, and notifies the intercom control unit 01 and the notification unit 08 of the signal “abnormal situation release” from the emergency response unit 12.
次にインターホン制御部０１で鍵開閉部１０が開錠を検知した時にスタートさせたタイマーがタイムアウトしたときについて説明する。タイムアウトするとインターホン制御部０１から信号『タイムアウト』を特定音声検知感度調整部０３へ送信し、特定音声検知感度調整部０３では検知感度を敏感な状態に保つ時間の終了を認識し、通常の検知感度を示す‘感度標準’を記憶保持する。この‘感度標準’を参照して、特定音声検知部０４は、室内音声の検知レベルを通常のレベルに戻すので、検知感度は鈍くなり、日常の会話で誤って異常事態発生となることを防止する。 Next, a case where the timer started when the key opening / closing unit 10 detects unlocking in the intercom control unit 01 times out will be described. When the time-out occurs, the intercom control unit 01 sends a signal “timeout” to the specific sound detection sensitivity adjustment unit 03. The specific sound detection sensitivity adjustment unit 03 recognizes the end of the time to keep the detection sensitivity in a sensitive state, and performs normal detection sensitivity. The 'sensitivity standard' indicating is stored. Referring to this 'sensitivity standard', the specific sound detection unit 04 returns the detection level of the room sound to the normal level, so the detection sensitivity becomes dull and prevents an abnormal situation from being accidentally generated in daily conversation. To do.
インターホン制御部０１は、信号『異常事態解除通知』を受信すると鍵開閉部１０から新たに送られてくる鍵の施錠、開錠情報を受信待ちする状態に入る。 When the intercom control unit 01 receives the signal “notification of cancellation of abnormal situation”, the intercom control unit 01 enters a state of waiting for reception of key locking / unlocking information newly sent from the key opening / closing unit 10.

The operation starts when the power is turned on (S200), and it is monitored whether the door 12 is opened (S201). When the door 12 is unlocked (S201: Yes), when the signal “unlocked” is sent from the key opening / closing unit 10, a signal “sensitivity increase” is sent to the specific voice detection sensitivity adjustment unit 03 to adjust the specific voice detection sensitivity. The unit 03 stores and holds “high sensitivity” (S210).
Further, the intercom control unit 01 activates a specific voice detection timer (not shown) (S211).
特定音声検知部０４でマイク０６からの室内音声と特定音声パターン登録部０５に予め登録された特定の音声とを常時照合し（Ｓ２２０のＮｏ，Ｓ２２４のＮｏ）、照合した結果、両者が一致した場合（Ｓ２２０のＹｅｓ）に、フローチャートには明記してないが、信号『特定音声検知』が緊急対応部０２に通知され、緊急対応部０２はこれを異常事態発生と判断し、信号『異常事態発生』をインターホン制御部０１及び通知部０８に送付する。 The specific voice detection unit 04 always collates the room voice from the microphone 06 with the specific voice registered in advance in the specific voice pattern registration unit 05 (No in S220, No in S224), and as a result of the collation, both are matched. In the case (Yes in S220), the signal “specific voice detection” is notified to the emergency response unit 02, and the emergency response unit 02 determines that an abnormal situation has occurred, and the signal “abnormal situation”. “Generate” is sent to the intercom control unit 01 and the notification unit 08.
