Description

【０００１】
【発明の属する技術分野】
本発明は、交換機等に接続され、要求に応じて加入者端末に常時時報メッセージを提供し得る時報メッセージ供給装置における電源の異常に伴なう警報を外部へ通知する警報送信方法及びシステムに関するものである。
【０００２】
【従来の技術】
時報メッセージ供給装置は、それぞれの地域の市外又は市内電話中継交換機に設置され、斯種の時報メッセージ供給装置は一般に、公共放送電波から検出した時報信号に基づいて時報メッセージを形成し、この時報メッセージを交換機に常時供給するようにして、加入者の要求に応じて加入者端末へ時報メッセージを伝送する。このような時報メッセージ供給装置は、時報メッセージを形成するための種々の回路、例えば水晶発振器、公共放送電波からの時報信号検出器、時刻計数回路、時刻信号を時刻メッセージの音声に編集する編集回路、秒音・時報音発生回路等具えており、これらの回路は装置用電源によってそれぞれ作動し、また、装置用電源は、時報メッセージ供給装置のメンテナンス作業を行う保守拠点の保守者に対して、その電源異常に伴なう警報通知を行なうためにも用いられている。前記装置用電源に異常が生じた場合の警報は、それを受信する警報受信装置のインタフェースによってそれぞれ異なる送信モードの警報信号として、時報メッセージ供給装置における警報送信回路から警報受信装置へと送信されている。
【０００３】
図３に示すように、従来の時報メッセージ供給装置１及び1aは、保守者にその装置用電源の異常を警報通知するために、それぞれインタフェースの異なる警報受信装置２及び2aとネットワーク３を介して接続されている。例えば、時報メッセージ供給装置１の電源異常等により警報の送出が必要な場合に、この時報メッセージ供給装置１における警報送信回路（図示せず）は警報受信装置２及び2aに向けて、固有の送信モード（例えば、「アース」モード）で警報信号s1を送信する。この場合に、警報受信装置２は、時報メッセージ供給装置１の警報送信回路から送信された警報信号s1を受信した場合に警報を認識し、また、警報受信装置2aは、時報メッセージ供給装置1aの警報送信回路に固有の送信モード（例えば、「電池」モード）で送信された警報信号s2を受信した場合に警報を認識するように構成されている。従って、時報メッセージ供給装置１における警報送信回路から警報発生時に送出される警報信号s1は、警報受信装置２にて受信されて警報が認識されるのに対し、警報受信装置2aは、時報メッセージ供給装置1aの警報送信回路から送信される警報信号s2の受信時にしか警報を認識することができず、警報受信装置2aは、時報メッセージ供給装置１の警報送信回路から送信される警報信号s1を直接受信することができない。このために警報受信装置2aでも時報メッセージ供給装置１の警報送信回路回路からの警報信号s1を受信できるようにするためには、インタフェース変換装置４にて警報信号s1を警報信号s2に一旦変換しなければ警報信号s1を受信することができなかった。
【０００４】
さらに、時報メッセージ供給装置１及び1aは、これらの装置の警報送信回路への警報用電源と、これらの時報メッセージ供給装置が時報メッセージを形成して供給するのに必要な装置用電源とを共有しているため、これらの時報メッセージ供給装置１及び1aに対し、何らかの要因で電源供給が停止した場合には、これらの時報メッセージ供給装置による時報メッセージの供給そのものが停止するにも拘わらず、時報メッセージ供給装置の異常を警報受信装置２及び2aへ通知することも行えず、保守者に対して時報メッセージ供給装置の装置異常を通知することができなかった。
【０００５】
【発明が解決しようとする課題】
上述したように従来は、時報メッセージ供給装置１又は1aの警報送信回路からネットワーク３を介して警報を警報受信装置２及び2aに送出する場合において、警報受信装置２のインタフェースは「警報信号s1」の受信用に、警報受信装置2aのインタフェースは「警報信号s2」の受信用と、それぞれ相違しているために、時報メッセージ供給装置１における警報送信回路から警報受信装置2aへの警報送信を行うためには、この警報受信装置2aとのインタフェース整合をとるために、インタフェース変換装置４を介して接続する必要があった。また、それぞれの時報メッセージ供給装置１及び1aは、警報受信装置２及び2aに対して警報を送出する警報送信回路への警報用電源と、時報メッセージの形成及び供給に必要な装置用電源を共有しているため、時報メッセージ供給装置１に供給している装置用電源に異常が生じた場合には、この時報メッセージ供給装置の時報メッセージの供給が停止した旨の警報ならびに、給電用電源が異常である旨の警報を保守者に知らせることもできなかった。
【０００６】
そこで、本発明の目的は、時報メッセージ供給装置の電源異常に伴なう警報を外部に確実に送信できる安価な方法及びシステムを提供することにある。
【０００７】

【００１５】
【発明の実施の形態】
本発明をより詳細に説述するために、添付の図面に従ってこれを説明する。
【００１６】
図１は本発明による時報メッセージ供給装置における電源の異常に伴なう警報送信システムの一実施例を示すブロック図である。この送信システムでは、時報メッセージ供給装置１０からネットワークを介して警報受信装置１１に対して警報を送信させる手段として、予め警報受信装置１１のインタフェースに合わせるために、遠隔保守運用端末１７からの指示により電話網を経て電話回路１５を介して設定されるか、もしくは現地保守運用端末１８からの操作により設定される装置制御回路１４の制御下にて送信モードが制御されて、警報受信装置１１のインタフェースに合った警報を警報受信装置１１に送信する外部警報送信回路１６を具えている。本発明ではこのような外部警報送信回路１６を用いることにより、従来必要とされていたインタフェース変換装置４（図３参照）への接続が不要となる。なお、時報メッセージ供給装置１０は、時報メッセージを形成して供給するための種々の回路、例えば水晶発振器、公共放送電波からの時報信号検出器、時刻計数回路、時刻信号を時刻メッセージの音声に編集する回路、秒音・時報音発生回路等も具えているが、これらは本発明の要部ではないために図示してない。
【００１７】
時報メッセージ供給装置１０の電源は、外部警報送信回路１６へ給電する警報用電源１３と、前記電話回路や、装置制御回路１４及び時報メッセージを形成して供給するための前述したような種々の回路にも給電するための装置用電源１４とに分割され、仮に警報用電源１３に異常が生じても、装置用電源１２によって電話回路１５を介して遠隔保守運用端末１７に自律発信し、保守者が遠隔保守運用端末１７に表示される警報を確認して、警報用電源１３の異常に早期に対処することができる。一方の装置用電源１２に異常があった場合においても、警報用電源１３より供給している外部警報送信回路１６より、警報受信装置１１に警報通知が可能となり、警報受信装置１１が受信した警報を保守者が認識することで、従来技術のように、警報が保守者に通知されなくなるようなことがなくなり、装置用電源１２の異常に早期に対処することができる。
【００１８】
次ぎに、装置用電源１２の監視について外部警報送信回路１６の接続構成を示している図２を用いて説明する。
【００１９】
時報メッセージ供給装置１０に供給している装置用電源１２の異常は、−４８Ｖ監視リレー２０によって監視されている。装置用電源１２の正常時には、この装置用電源１２より供給される電圧により、−４８Ｖ監視リレー２０が動作しており、−４８Ｖ監視リレー接点２２がブレイク状態にあるため、警報受信装置１１に対して、警報送出は行われないが、装置用電源１２に異常が生じた場合には、−４８Ｖ監視リレー２０が動作しなくなり、−４８監視リレー接点２２がメーク状態となるために、警報受信装置１１に対し警報が送出されるようになる。なお、図では示してないが、−４８Ｖ監視リレー接点２２は−４８Ｖ監視リレー２０に接続されている。
【００２０】
次に、警報受信装置１１に警報送出を可能とするための外部警報送信回路１６の動作について、同じく図２を参照して説明する。
【００２１】
先ず、外部警報送信回路１６による警報送信モードを、例えば「電池」モードとする場合について説明する。この場合には、外部警報送信回路１６の第１のモード選択（「電池」＆「アース」モード選択）リレー１９を遠隔保守運用端末１７（図１参照）の指示により設定した装置制御回路１４の制御のもとでメーク保持状態とすると共に、第２のモード選択（「ループ」モード選択）リレー２３を同じく遠隔保守運用端末１７（図１）の指示により設定した装置制御回路１４の制御のもとでブレイク保持状態とし、警報用電源１３からの電圧が、第１のモード選択リレー１９のメーク接点、第２のモード選択リレー２３のブレイク接点を介し、警報受信装置１１に警報として送信される。
【００２２】
次に、外部警報送信回路１６による警報送信モードを、例えば「アース」モードとする場合について説明する。この場合には、外部警報送信回路１６の第１のモード選択リレー１９を遠隔保守運用端末１７の指示により設定した装置制御回路１４の制御のもとでブレイク保持状態とし、第２のモード選択リレー２３を同じく遠隔保守運用端末１７の指示により設定した装置制御回路１４の制御のもとでブレイク保持状態とした状態で、アース２１からのアース電位の電圧が、第１のモード選択リレー１９のブレイク接点、第２のモード選択リレー２３のブレイク接点を介し、警報受信装置１１に警報として送信される。
【００２３】
次に、外部警報送信回路による警報送信モードを、例えば「ループ」モードとする場合について説明する。この場合には、外部警報送信回路１６は第１のモード選択リレー１９に依存せず、第２のモード選択リレー２３を装置制御回路１４の指示によりメーク保持状態とし、警報受信装置１１と外部警報送信回路１６との間にループが形成されることにより、このループ形成が警報受信装置１１に警報として送信される。
【００２４】
以上、装置用電源１２に異常が生じた場合に警報受信装置１１への警報の送信態様につき説明したが、次ぎに、警報用電源１３の監視について外部警報送信回路１６の接続構成を図２及び図３を用いて説明する。
【００２５】
警報用電源１３に異常が生じた場合には、外部警報送信回路１６の第１のモード選択リレー１９が電源異常を認識する。この場合には、警報用電源１３が異常のため、この電源１３によって動作していた第２のモード選択リレー２３及び、第１のモード選択リレー１９が動作できなくなり、警報用電源１３異常時の通知を、警報受信装置１１に対して行えなくなる。しかし、装置制御回路１４が、警報用電源１３の監視を行っている警報用電源監視９（図１参照）からの電源異常情報を受けて、その電源異常を認識すると、電話回路１５を経由し、遠隔保運用端末１７に対して通知を行うため、保守者に対しては警報用電源が異常である旨の通知を行うことが可能である。
【００２６】
【発明の効果】
時報メッセージ供給装置の電源を装置用電源と、警報用電源とに分離することにより、装置用電源に異常があっても、警報用電源を用いて警報受信装置に警報送信が行えるため、確実な警報伝達が可能である。外部警報送信回路の警報信号送信モードの選択機能は、遠隔保守運用端末等により警報受信装置の複数のインタフェースに対応させることができることにより、インタフェース変換装置が不要となることから、従来方式に比較し安価な設備構築ができる。

BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to an alarm transmission method and system for notifying the outside of an alarm associated with a power failure in a time signal message supply device connected to an exchange or the like and capable of always providing a time signal message to a subscriber terminal upon request. It is.
[0002]
[Prior art]
The time signal message supply device is installed in a local area or in a local telephone relay exchange, and such a time signal message supply device generally forms a time signal message based on a time signal signal detected from a public broadcast radio wave. The time signal message is transmitted to the subscriber terminal in response to the request of the subscriber by always supplying the time signal message to the exchange. Such a time signal message supply device includes various circuits for forming a time signal message, such as a crystal oscillator, a time signal signal detector from a public broadcast radio wave, a time counting circuit, and an editing circuit that edits the time signal into the sound of the time message. , Second sound / time signal sound generation circuit, etc., these circuits are each operated by the power supply for the device, and the power supply for the device is for maintenance personnel at the maintenance base that performs maintenance work of the time signal message supply device, It is also used to provide alarm notifications associated with the power supply abnormality. When an abnormality occurs in the power supply for the device, an alarm is transmitted from the alarm transmission circuit in the time signal message supply device to the alarm reception device as an alarm signal in a different transmission mode depending on the interface of the alarm reception device that receives the alarm. Yes.
[0003]
As shown in FIG. 3, the conventional time signal supply devices 1 and 1a are connected to the maintenance personnel via alarms 2 and 2a having different interfaces and the network 3 in order to notify the maintenance person of an abnormality in the power supply for the device. It is connected. For example, when it is necessary to send an alarm due to an abnormality in the power supply of the time signal message supply device 1, an alarm transmission circuit (not shown) in the time signal message supply device 1 transmits a specific transmission to the alarm reception devices 2 and 2a. The alarm signal s1 is transmitted in a mode (eg, “earth” mode). In this case, the alarm receiver 2 recognizes the alarm when the alarm signal s1 transmitted from the alarm transmission circuit of the hourly message supply device 1 is received, and the alarm receiver 2a is connected to the hourly message supply device 1a. An alarm is recognized when an alarm signal s2 transmitted in a transmission mode (eg, “battery” mode) unique to the alarm transmission circuit is received. Accordingly, the alarm signal s1 sent from the alarm transmission circuit in the hourly message supply device 1 when the alarm is generated is received by the alarm receiver 2 and the alarm is recognized, whereas the alarm receiver 2a is supplied with the hourly message. The alarm can be recognized only when the alarm signal s2 transmitted from the alarm transmission circuit of the device 1a is received, and the alarm reception device 2a directly receives the alarm signal s1 transmitted from the alarm transmission circuit of the hourly message supply device 1. Cannot receive. For this reason, in order to enable the alarm receiver 2a to receive the alarm signal s1 from the alarm transmission circuit of the time signal message supply apparatus 1, the interface converter 4 once converts the alarm signal s1 into the alarm signal s2. Without it, the alarm signal s1 could not be received.
[0004]
Further, the hourly message supply devices 1 and 1a share the alarm power supply to the alarm transmission circuit of these devices and the device power supply necessary for these hourly message supply devices to form and supply the hourly message. Therefore, when the power supply to these hourly message supply devices 1 and 1a is stopped for some reason, the hourly message supply by these hourly message supply devices is stopped even though the supply of the hourly message itself is stopped. It was also impossible to notify the alarm receivers 2 and 2a of the abnormality of the message supply device, and it was impossible to notify the maintenance person of the device abnormality of the time signal message supply device.
[0005]
[Problems to be solved by the invention]
As described above, conventionally, when an alarm is sent from the alarm transmission circuit of the hourly message supply device 1 or 1a to the alarm reception devices 2 and 2a via the network 3, the interface of the alarm reception device 2 is “alarm signal s1”. Since the interface of the alarm receiving device 2a is different from that for receiving the “alarm signal s2”, the alarm transmission from the alarm transmission circuit in the hourly message supply device 1 to the alarm receiving device 2a is transmitted. Therefore, it is necessary to connect via the interface conversion device 4 in order to achieve interface matching with the alarm receiving device 2a. In addition, each time signal message supply device 1 and 1a share a power source for alarms to an alarm transmission circuit that sends an alarm to the alarm reception devices 2 and 2a, and a power source for devices necessary for the formation and supply of time signal messages. Therefore, when an abnormality occurs in the power supply for the device supplied to the time signal message supply device 1, an alarm that the supply of the time signal message of the time signal message supply device has stopped and the power supply for power supply is abnormal. It was not possible to notify the maintenance personnel of the alarm.
[0006]

The transmission mode is controlled under the control of the device control circuit 14 which is set via the telephone network 15 via the telephone circuit 15 or by an operation from the local maintenance operation terminal 18, and the interface of the alarm receiving device 11 An external alarm transmission circuit 16 for transmitting an alarm suitable for the above to the alarm receiver 11 is provided. In the present invention, the use of such an external alarm transmission circuit 16 eliminates the need for connection to the interface converter 4 (see FIG. 3), which has been conventionally required. The hourly message supply device 10 edits various circuits for forming and supplying hourly messages, such as a crystal oscillator, a hourly signal detector from a public broadcast radio wave, a time counting circuit, and a time signal into voice of the time message. However, these circuits are not shown because they are not essential parts of the present invention.

[0018]
Next, monitoring of the apparatus power supply 12 will be described with reference to FIG. 2 showing the connection configuration of the external alarm transmission circuit 16.
[0019]
An abnormality of the device power supply 12 supplied to the hourly message supply device 10 is monitored by the -48V monitoring relay 20. When the device power supply 12 is normal, the voltage supplied from the device power supply 12 operates the -48V monitoring relay 20, and the -48V monitoring relay contact 22 is in a break state. Although no alarm is sent, if an abnormality occurs in the power supply 12 for the device, the -48V monitoring relay 20 stops operating, and the -48 monitoring relay contact 22 is in a make state. 11 will be alerted. Although not shown in the figure, the −48V monitoring relay contact 22 is connected to the −48V monitoring relay 20.
[0020]
Next, the operation of the external alarm transmission circuit 16 for enabling alarm transmission to the alarm receiver 11 will be described with reference to FIG.
[0021]
First, the case where the alarm transmission mode by the external alarm transmission circuit 16 is set to, for example, the “battery” mode will be described. In this case, the first mode selection (“battery” & “earth” mode selection) relay 19 of the external alarm transmission circuit 16 is set according to the instruction of the remote maintenance operation terminal 17 (see FIG. 1). Under the control, the make-holding state is set, and the second mode selection (“loop” mode selection) relay 23 is set according to the instruction from the remote maintenance operation terminal 17 (FIG. 1). And the voltage from the alarm power supply 13 is transmitted as an alarm to the alarm receiver 11 via the make contact of the first mode selection relay 19 and the break contact of the second mode selection relay 23. .
[0022]
Next, the case where the alarm transmission mode by the external alarm transmission circuit 16 is, for example, the “earth” mode will be described. In this case, the first mode selection relay 19 of the external alarm transmission circuit 16 is brought into the break holding state under the control of the device control circuit 14 set by the instruction of the remote maintenance operation terminal 17, and the second mode selection relay 23 is set in the break holding state under the control of the device control circuit 14 which is also set by the instruction of the remote maintenance operation terminal 17, the voltage of the earth potential from the earth 21 is the break of the first mode selection relay 19. The signal is transmitted as an alarm to the alarm receiver 11 via the contact and the break contact of the second mode selection relay 23.
[0023]
Next, the case where the alarm transmission mode by the external alarm transmission circuit is set to, for example, the “loop” mode will be described. In this case, the external alarm transmission circuit 16 does not depend on the first mode selection relay 19, and the second mode selection relay 23 is set to the make-hold state according to the instruction of the device control circuit 14, and the alarm reception device 11 and the external alarm By forming a loop with the transmission circuit 16, this loop formation is transmitted to the alarm receiver 11 as an alarm.
[0024]
As described above, the transmission mode of the alarm to the alarm receiver 11 when the abnormality occurs in the apparatus power supply 12 has been described. Next, the connection configuration of the external alarm transmission circuit 16 for monitoring the alarm power supply 13 is shown in FIG. This will be described with reference to FIG.
[0025]
When an abnormality occurs in the alarm power supply 13, the first mode selection relay 19 of the external alarm transmission circuit 16 recognizes the power supply abnormality. In this case, since the alarm power supply 13 is abnormal, the second mode selection relay 23 and the first mode selection relay 19 that have been operated by the power supply 13 cannot be operated, and the alarm power supply 13 is in an abnormal state. Notification cannot be performed to the alarm receiver 11. However, when the device control circuit 14 receives the power supply abnormality information from the alarm power supply monitor 9 (see FIG. 1) that monitors the alarm power supply 13 and recognizes the power supply abnormality, it passes through the telephone circuit 15. Since the remote maintenance operation terminal 17 is notified, the maintenance person can be notified that the alarm power supply is abnormal.
[0026]
