Are well known to those skilled in the art, and their detailed configuration will not be described.

次に図１の通報システムの動作を説明する。 Next, the operation of the notification system in FIG. 1 will be described.

図１及び図２において、本通報システムでは、通報装置１０は、通常運用時（即ち、警備端末５０からの接点入力がＯＮ（３．３Ｖとする）である場合）においては、使用者がハンドセット１２を取り上げることによってオフフック状態とされる。その状態で、通報装置１０において、使用者が呼出ボタン１００を押下すると、通報装置１０のＣＰＵ１６１は、ＥＥＰＲＯＭ１５に予め登録されている宛先(センタ装置３０)へ自動発報し、使用者はセンタ装置３０と通話が可能となる。 1 and 2, in this notification system, the notification device 10 allows the user to use the handset during normal operation (that is, when the contact input from the security terminal 50 is ON (3.3 V)). By picking up 12, it goes off-hook. In this state, when the user presses the call button 100 in the notification device 10, the CPU 161 of the notification device 10 automatically issues a destination (center device 30) registered in advance in the EEPROM 15, and the user selects the center device. Talking with 30 is possible.

ただし、警備端末５０がセンサ情報の異常発生を検出した時、通報装置１０においては警備端末５０からの接点入力がＯＦＦ(０Ｖとする)となる。警備端末５０からの接点入力がＯＦＦした場合（警備端末５０から通報があった場合）と、通報装置１０のＣＰＵ１６１は、通話パスの切替えを行い(センタ装置３０と通話している場合は強制切断し、ハンドセット１２へビジートーンを送出する)、警備端末５０からのアナログポートを介しての警備端末データを含む通報データ（モデム通信とする）をセンタ装置３０へ送信する。 However, when the security terminal 50 detects an abnormality in the sensor information, the contact input from the security terminal 50 is turned off (set to 0 V) in the notification device 10. When the contact input from the security terminal 50 is turned off (when a report is received from the security terminal 50), the CPU 161 of the reporting device 10 switches the call path (forcibly disconnects when talking with the center device 30). Then, a busy tone is sent to the handset 12), and report data (modem communication) including guard terminal data from the guard terminal 50 via the analog port is transmitted to the center device 30.

次に、本通報システムにおいて、通報装置１０の保守自動点検を行う際の動作について説明する。 Next, the operation when performing automatic maintenance inspection of the reporting device 10 in this reporting system will be described.

図１及び図２において、本通報システムにおいては、通報装置１０の保守自動点検を行う際には、センタ装置３０がＰＨＳ網及び公衆網４０を介して通報装置１０に保守メンテナンスコマンドを送信する。 In FIG. 1 and FIG. 2, in this notification system, when performing automatic maintenance inspection of the notification device 10, the center device 30 transmits a maintenance command to the notification device 10 via the PHS network and the public network 40.

通報装置１０は、制御部１６のＣＰＵ１６１が、センタ装置３０からの保守メンテナンスコマンドをアンテナ２７及びＰＨＳモジュール１８を介して受信すると、制御部１６のＣＰＵ１６１の制御下で以下の動作を行う。 When the CPU 161 of the control unit 16 receives a maintenance command from the center device 30 via the antenna 27 and the PHS module 18, the reporting device 10 performs the following operation under the control of the CPU 161 of the control unit 16.

即ち、まず、ＤＴＭＦ回路１４２においてＤＴＭＦ信号(例えばＰＢ８)を発信し、通話回路１４１において、発信されたＤＴＭＦ信号の信号レベルを増幅し、増幅されたＤＴＭＦ信号を内蔵スピーカ１１からハンドセットマイク１２Ｍへ送出する(送出レベルは任意とする)。 That is, first, the DTMF circuit 142 transmits a DTMF signal (for example, PB8), the call circuit 141 amplifies the signal level of the transmitted DTMF signal, and sends the amplified DTMF signal from the built-in speaker 11 to the handset microphone 12M. Yes (the sending level is arbitrary).

送出されたＤＴＭＦ信号は、ハンドセットマイク１２Ｍから通話回路（送話パス２００を構成する送話パス用通話回路）１４１を介しＤＴＭＦ回路１４２に導かれ、ＤＴＭＦ回路１４２において、ＤＴＭＦ信号を検出する。 The transmitted DTMF signal is guided from the handset microphone 12M to the DTMF circuit 142 via the call circuit (speech path call circuit constituting the transmission path 200) 141, and the DTMF circuit 142 detects the DTMF signal.

続いて、ＤＴＭＦ回路１４２においてＤＴＭＦ信号(例えばＰＢ８)を発信し、通話回路（受話パス３００を構成する受話パス用通話回路）１４１において、発信されたＤＴＭＦ信号の信号レベルを増幅し、増幅されたＤＴＭＦ信号をハンドセットレシーバ１２Ｒから内蔵マイク１３へ送出する(送出レベルは任意とする)。 Subsequently, a DTMF signal (for example, PB8) is transmitted in the DTMF circuit 142, and the signal level of the transmitted DTMF signal is amplified and amplified in the communication circuit (the reception path communication circuit constituting the reception path 300) 141. A DTMF signal is transmitted from the handset receiver 12R to the built-in microphone 13 (the transmission level is arbitrary).

送出されたＤＴＭＦ信号は、内蔵マイク１３から通話回路１４３を介しＤＴＭＦ回路１４２に導かれ、ＤＴＭＦ回路１４２において、ＤＴＭＦ信号を検出する。 The sent DTMF signal is guided from the built-in microphone 13 to the DTMF circuit 142 via the call circuit 143, and the DTMF circuit 142 detects the DTMF signal.

上記動作を実施する事によって、通報装置１０の通話回路（送受話）１４１、内蔵スピーカ１１、内蔵マイク１３、及び音声回路部１４、ハンドセット１２のハンドセットマイク１２Ｍ及びハンドセットレシーバ１２Ｒに問題ない事を確認できる。 By performing the above operation, it is confirmed that there is no problem in the communication circuit (transmission / reception) 141, the built-in speaker 11, the built-in microphone 13, and the voice circuit unit 14, the handset microphone 12M of the handset 12 and the handset receiver 12R. it can.

その他ＲＯＭ１６２のリード、ＲＡＭ１６３のリード及びライト、フックスイッチ検出回路２３の状態検出、呼出ボタン検出回路２４の呼出ボタン１００の状態検出等のチェックしたら、時刻を含めた保守自動点検動作結果をＥＥＰＲＯＭ１５内に保存すると共にセンタ装置３０へも送信する。 When the ROM 162 is read, the RAM 163 is read and written, the state of the hook switch detection circuit 23 is detected, the state of the call button 100 of the call button detection circuit 24 is detected, the result of the automatic maintenance check operation including the time is stored in the EEPROM 15. The data is stored and transmitted to the center device 30.

通報装置１０の保守自動点検動作中に警備端末５０から通報があった場合には、通報装置１０のＣＰＵ１６１は、警備端末５０からの通報データをＲＡＭ１６３或いはＥＥＰＲＯＭ１５内にバッファしておき、センタ装置３０へ保守自動点検動作結果を送信後、通報データをセンタ装置３０へ送信する。 When a notification is received from the security terminal 50 during the maintenance automatic inspection operation of the notification device 10, the CPU 161 of the notification device 10 buffers the notification data from the security terminal 50 in the RAM 163 or the EEPROM 15, and the center device 30. After transmitting the result of the maintenance automatic inspection operation, the notification data is transmitted to the center device 30.

なお、図２の通報装置１０では、ＤＴＭＦ信号を音信号として用い、ＤＴＭＦ信号にて通話機能確認を行っているが、音信号としてコール・プログレス・トーンを用い、コール・プログレス・トーンにて通話機能確認を行っても良い。 2 uses the DTMF signal as a sound signal and performs a call function check using the DTMF signal. However, the call progress tone is used as the sound signal and the call progresses using the call progress tone. You may check the function.

また、送話パス２００の確認にはＤＴＭＦ信号及びコール・プログレス・トーンの一方を用い、受話パス３００の確認にはＤＴＭＦ信号及びコール・プログレス・トーンの他方を用いても良い。 One of the DTMF signal and the call progress tone may be used for confirming the transmission path 200, and the other of the DTMF signal and the call progress tone may be used for confirming the reception path 300.

また、図２の通報装置１０では、送話パス２００を自動点検してから受話パス３００を自動点検しているが、送話パス２００の確認にはＤＴＭＦ信号及びコール・プログレス・トーンの一方を用い、受話パス３００の確認にはＤＴＭＦ信号及びコール・プログレス・トーンの他方を用いることによって、送話パス２００及び受話パス３００の自動点検を同時に行っても良い。 2 automatically checks the transmission path 200 and then automatically checks the reception path 300. To confirm the transmission path 200, one of the DTMF signal and the call progress tone is used. In use, the other of the DTMF signal and the call progress tone may be used to confirm the reception path 300, so that the transmission path 200 and the reception path 300 may be automatically checked at the same time.

以上説明したように、本実施形態においては、自動にて送話パス２００及び受話パス３００の動作確認が可能となり、保守作業員の作業時間を短縮できる。運用によっては保守作業員が不要となる。 As described above, in the present embodiment, it is possible to automatically check the operation of the transmission path 200 and the reception path 300, and the work time of the maintenance worker can be shortened. Depending on the operation, maintenance workers are not required.

The hollow guide portion 102 has a function of guiding (returning) a DTMF signal (sound signal) emitted from the handset receiver 12R to the handset microphone 12M when the handset 12 is placed on the notification device main body 101 (the notification device 10 is in an on-hook state). Have

この通報装置１０’は、制御部１６のＣＰＵ１６１が、センタ装置３０からの保守メンテナンスコマンドをアンテナ２７及びＰＨＳモジュール１８を介して受信すると、制御部１６のＣＰＵ１６１の制御下で以下の動作を行う。 When the CPU 161 of the control unit 16 receives a maintenance command from the center device 30 via the antenna 27 and the PHS module 18, the notification device 10 'performs the following operation under the control of the CPU 161 of the control unit 16.

即ち、ＤＴＭＦ回路(音信号送出及び検出部)１４２においてＤＴＭＦ信号(例えばＰＢ８)を発信し、通話回路（受話パス３００を構成する受話パス用通話回路）１４１において、発信されたＤＴＭＦ信号の信号レベルを増幅し、増幅されたＤＴＭＦ信号をハンドセットレシーバ１２Ｒから空洞ガイド部１０２へ送出する(送出レベルは任意とする)。 That is, the DTMF signal (for example, PB8) is transmitted in the DTMF circuit (sound signal transmission and detection unit) 142, and the signal level of the transmitted DTMF signal is transmitted in the communication circuit (the reception path communication circuit constituting the reception path 300) 141. And the amplified DTMF signal is sent from the handset receiver 12R to the cavity guide unit 102 (the sending level is arbitrary).
