Description

本発明は、自動発信システムに使用する相手応答検出に関するものである。   The present invention relates to counterpart response detection used in an automatic transmission system.

従来の自動発信システムに使用する相手応答検出は、相手が応答したことによる電圧極性反転を検出しているので、相手が応答しても電圧極性反転が得られない電話回線（警察署、消防署）の場合は、相手応答を確定することができなかった。このような問題を解決するために、ダイヤル番号送出後の相手呼出中信号を検出し、該相手呼出中信号の検出後、該相手呼出中信号の停止を検出することにより相手応答と判断する工夫がなされている（例えば、特許文献１参照）。   The other party's response detection used in the conventional automatic transmission system detects a voltage polarity reversal due to the other party's response, so a telephone line that cannot obtain a voltage polarity reversal even if the other party responds (police station, fire department) In the case of, the other party's response could not be confirmed. In order to solve such a problem, a device for detecting the other party's ringing signal after sending the dial number, and detecting the other party's ringing signal after detecting the other party's calling signal, is determined to be the other party's response (For example, refer to Patent Document 1).

しかし、このような工夫にあっても、相手呼出中信号の検出後、火災・犯罪・事故等の理由により自動発信システム側の電話回線が切断された場合、相手応答と見なしてしまい確実に相手応答検出をすることができず、相手応答を確定することができないという問題がある。
特公平３−２４１１３号公報 However, even with this ingenuity, if the telephone line on the automatic call system side is disconnected due to fire, crime, accident, etc. after detecting the other party's ringing signal, it will be regarded as the other party's response and the other party will be surely There is a problem that the response cannot be detected and the other party's response cannot be determined.
Japanese Patent Publication No. 3-24113

上記問題に鑑み、本発明は、相手応答自動検出方法および相手応答自動検出装置において、相手呼出中信号の検出後、火災・犯罪・事故等の理由により自動発信システム側の電話回線が切断された場合、相手応答と見なさず、誤った相手応答検出を防止することを目的とする。   In view of the above problems, in the other party automatic response detection method and the other party automatic response detection apparatus, after detecting the other party calling signal, the telephone line on the automatic transmission system side is disconnected due to a fire, crime, accident, or the like.

There is an advantage that a series of sequence of automatic transmission → partner response → communication (report) → completion → end talk can be completed with certainty.

以下、図を用いて、緊急通報装置である通信端末装置を例にして本発明の構成を説明する。図１〜図３は、本発明の第一の実施例にかかる緊急通報装置の構成を示す図であって、本説明はこの緊急通報装置に限定されず、例えば、自動通報装置などの通信端末装置であってもよい。   Hereinafter, the configuration of the present invention will be described using a communication terminal device, which is an emergency call device, as an example with reference to the drawings. 1-3 is a figure which shows the structure of the emergency call apparatus concerning the 1st Example of this invention, Comprising: This description is not limited to this emergency call apparatus, For example, communication terminals, such as an automatic notification apparatus It may be a device.

FIG. 2 is a diagram for explaining the outline of the configuration of the telephone line disconnection detection unit. FIG. 3 is a flowchart of partner response detection in the partner response detection unit.

図１に示すように、本発明にかかる通信端末装置１は、網制御部１１と、メッセージ送出部１２と、相手呼出中信号検出部１３と、電話回線切断検出部１４と、制御部１５とを有して構成される。   As shown in FIG. 1, a communication terminal device 1 according to the present invention includes a network control unit 11, a message sending unit 12, a partner calling signal detection unit 13, a telephone line disconnection detection unit 14, and a control unit 15. It is comprised.

網制御部１１は、電話回線２に接続され、電話回線２へのダイヤル発信と、メッセージ送信と、相手呼出中信号の受信を行うためのインターフェース回路である。   The network control unit 11 is connected to the telephone line 2 and is an interface circuit for performing dial transmission to the telephone line 2, message transmission, and reception of a partner calling signal.

メッセージ送出部１２は、制御部１５の相手応答検出出力により、網制御部１１を通して電話回線２に対してあらかじめ登録したメッセージを送出する回路である   The message sending unit 12 is a circuit that sends a pre-registered message to the telephone line 2 through the network control unit 11 based on the partner response detection output of the control unit 15.

相手呼出中信号検出部１３は、相手呼出中信号の検出と前記相手呼出中信号の停止検出を行う回路である。   The other party calling signal detector 13 is a circuit that detects the other party calling signal and detects the stop of the other party calling signal.

電話回線切断検出部１４は、電話回線が切断されたことを検出する回路であり、電話回線切断監視信号を出力する。   The telephone line disconnection detection unit 14 is a circuit that detects that the telephone line has been disconnected, and outputs a telephone line disconnection monitoring signal.

電話回線切断検出部１４の構成の概略を、図２を用いて説明する。電話回線切断検出部１４は、ダイオードブリッジ１４１と、電流制限抵抗１４２と、コンデンサ１４３と、放電抵抗１４４と、コンパレータ１４５と、ホトカップラー１４６と、スイッチング手段であるトランジスタ１４７と、バイアス抵抗１４８とを有して構成される。   An outline of the configuration of the telephone line disconnection detection unit 14 will be described with reference to FIG. The telephone line disconnection detection unit 14 includes a diode bridge 141, a current limiting resistor 142, a capacitor 143, a discharge resistor 144, a comparator 145, a photocoupler 146, a transistor 147 serving as switching means, and a bias resistor 148. It is configured.

ダイオードブリッジ１４１は、電話回線２に供給されている電圧を整流する手段であり、電話回線２に供給されている電圧を、電話回線２に影響を与えない電流制限抵抗１４２を介し、コンデンサ１４３に充電する。   The diode bridge 141 is a means for rectifying the voltage supplied to the telephone line 2, and the voltage supplied to the telephone line 2 is supplied to the capacitor 143 via the current limiting resistor 142 that does not affect the telephone line 2. Charge.

コンパレータ１４５は、コンデンサ１４３の充電電圧を監視し、充電電圧が一定値以上になると、トランジスタ１４７を導通させ、コンデンサ１４３に充電された電力を、放電抵抗１４４を介してホトカップラー１４６の発光部の発光ダイオード１４６Ａに流し、受光部のトランジスタ１４６Ｂを動作させて、バイアス抵抗１４８を介して供給される電圧を、電話回線２と絶縁された電話回線切断監視信号として制御部１５に断続的に出力する。   The comparator 145 monitors the charging voltage of the capacitor 143. When the charging voltage exceeds a certain value, the comparator 145 causes the transistor 147 to conduct, and the power charged in the capacitor 143 is supplied to the light-emitting unit of the photocoupler 146 via the discharge resistor 144. The voltage supplied through the bias resistor 148 is intermittently output to the control unit 15 as a telephone line disconnection monitoring signal insulated from the telephone line 2 by operating the transistor 146B of the light receiving unit. .

制御部１５は、網制御部１１に対して相手ダイヤル番号の送出を指示する機能と、相手呼出中音検出部１３の状態と、電話回線切断検出部１４からの電話回線切断監視信号が断続的に出力されていれば、相手が該自動発信に応答したことを示す相手応答信号を出力し、メッセージ送出部１２に対して、信号（メッセージ）の送出を指示する機能を有する。制御部１５は、電話回線切断検出部１４の電話回線切断監視信号が停止している場合は、電話回線が切断されていると判断し、回線を終話し、再度ダイヤル発信から繰り返す。   The control unit 15 intermittently receives a function for instructing the network control unit 11 to send the other party dial number, the state of the other party ringing tone detection unit 13, and the telephone line disconnection monitoring signal from the telephone line disconnection detection unit 14. Is output, the other party response signal indicating that the other party has responded to the automatic transmission is output, and the message sending unit 12 is instructed to send a signal (message). When the telephone line disconnection monitoring signal from the telephone line disconnection detection unit 14 is stopped, the control unit 15 determines that the telephone line is disconnected, terminates the line, and repeats from dialing again.

このような通信端末装置１において、電話回線切断検出部１４は、電話回線２に電圧が印加されているときには、コンデンサ１４３が電話回線２によって電流制限抵抗１４２を経由して充電され、所定の電圧となるとコンパレータ１４５がトランジスタ１４７をＯＮとして、放電抵抗１４４およびホトカップラー１４６の発光ダイオード１４６Ａを介して放電される。コンパレータ１４５は、入力電圧が所定の電圧に達したことを検出して動作する第１の電圧と、動作後入力電圧が低下して動作を停止する第２の電圧との間にヒステリシスを有しており、動作を開始する第１の電圧よりも低い第２の所定の電圧に達した点で動作を停止する。したがって、コンデンサ１４３が放電を開始して所定の時間が経過してコンデンサ１４３の電圧が第２の電圧に達すると、トランジスタ１４７はＯＦＦとされる。したがって、電話回線が切断されていないときには、電話回線切断監視信号は所定の周期で、ＯＮ／ＯＦＦを繰り返す。   In such a communication terminal device 1, when a voltage is applied to the telephone line 2, the telephone line disconnection detection unit 14 is charged with the capacitor 143 by the telephone line 2 via the current limiting resistor 142, and has a predetermined voltage. Then, the comparator 145 turns on the transistor 147 and is discharged through the discharge resistor 144 and the light emitting diode 146A of the photocoupler 146. Comparator 145 has a hysteresis between a first voltage that operates by detecting that the input voltage has reached a predetermined voltage, and a second voltage that stops operation when the input voltage decreases after operation. The operation is stopped when a second predetermined voltage lower than the first voltage at which the operation starts is reached. Therefore, when the capacitor 143 starts discharging and a predetermined time elapses and the voltage of the capacitor 143 reaches the second voltage, the transistor 147 is turned off. Therefore, when the telephone line is not disconnected, the telephone line disconnection monitoring signal repeats ON / OFF at a predetermined cycle.

制御部１５は、電話回線切断検出部１４からの電話回線切断監視信号が繰り返して出力されているときには、電話回線は接続状態と判断し、電話回線切断監視信号の断続出力が停止し、一定電圧（ハイレベル）のままになると、回線が切断されたと判断する。   When the telephone line disconnection monitoring signal from the telephone line disconnection detection unit 14 is repeatedly output, the control unit 15 determines that the telephone line is in a connected state, stops the intermittent output of the telephone line disconnection monitoring signal, and outputs a constant voltage. If it remains (high level), it is determined that the line has been disconnected.

相手応答検出を実現するための通信端末１における処理を、図３を用いて説明する。図３は、相手応答検出の概要処理フローチャートである。まず、通報要因が発生すると、制御部１５から網制御部１１に相手ダイヤル番号送出を指示し、電話回線２に対して相手ダイヤル番号を送出する（Ｓ１）。   Processing in the communication terminal 1 for realizing partner response detection will be described with reference to FIG. FIG. 3 is a flowchart of an outline process of partner response detection. First, when a reporting factor occurs, the control unit 15 instructs the network control unit 11 to send the other party dial number and sends the other party dial number to the telephone line 2 (S1).

相手ダイヤル番号送出後、相手呼出中信号検出部１３で相手呼出中信号検出を開始する（Ｓ２）。この相手呼出中信号検出を行う処理を相手呼出中信号検出処理という。相手呼出中信号を検出すると（Ｓ３：Ｙｅｓ）、次に、相手呼出中信号検出部１３で相手呼出中信号停止の検出を開始する（Ｓ４）。なお、相手呼出中信号は電話回線２の先に接続された交換機からの信号（４００Ｈｚ）であり、この信号の検出は４００Ｈｚを検出すればよく、従来よりある公知の任意の方法または手段が適用可能である。   After sending the other party dial number, the other party calling signal detection unit 13 starts detecting the other party calling signal (S2). This process of detecting the other party call signal is called the other party call signal detection process. When the other party calling signal is detected (S3: Yes), the other party calling signal detection unit 13 starts detecting the other party calling signal stop (S4). The other party calling signal is a signal (400 Hz) from an exchange connected to the end of the telephone line 2, and this signal may be detected by detecting 400 Hz, and any conventionally known method or means can be applied. Is possible.

相手呼出中信号の停止を検出する（Ｓ４：Ｙｅｓ）と、前記電話回線切断監視信号によって電話回線切断検出を行う（Ｓ５）。この電話回線切断検出を行う処理を回線接続状態検出処理という。電話回線切断検出が無い（Ｓ５：Ｎｏ）場合、制御部１５は相手が応答したことを示す相手応答信号を出力し（制御部１５内処理）、制御部１５からメッセージ送出部１２に対してメッセージ送出開始を指示し、メッセージ送出を開始する（Ｓ７）、メッセージの送出が完了したら、通報完了とする（Ｓ８）。   When the stop of the other party calling signal is detected (S4: Yes), the telephone line disconnection is detected by the telephone line disconnection monitoring signal (S5). This process of detecting a telephone line disconnection is called a line connection state detection process. If there is no detection of disconnection of the telephone line (S5: No), the control unit 15 outputs a partner response signal indicating that the other party has responded (processing in the control unit 15), and the control unit 15 sends a message to the message sending unit 12. Sending is instructed to start sending a message (S7). When sending of the message is completed, the notification is completed (S8).

ステップ５で、電話回線切断検出がある場合（Ｓ５：Ｙｅｓ）、電話回線が切断されたと判断して通報失敗（Ｓ６）に移行し、再度ダイヤル発信（Ｓ１）に戻る。   If it is detected in step 5 that the telephone line has been disconnected (S5: Yes), it is determined that the telephone line has been disconnected, the process proceeds to report failure (S6), and the process returns to dial transmission (S1) again.

このようにして、相手応答自動検出機能を備えた通信端末装置において、相手呼出中信号の検出後、相手呼出中信号の停止を検出した場合でも、火災・犯罪・事故等の理由により自動発信システム側の電話回線が切断された場合には、電話回線の切断を確実に検出することができ、誤った相手応答検出を防止して確実に相手応答検出を判断することができる。   In this way, in the communication terminal device equipped with the other party response automatic detection function, even after detecting the other party calling signal, even if the other party calling signal stop is detected, the automatic transmission system for fire, crime, accident, etc. When the telephone line on the side is disconnected, it is possible to reliably detect disconnection of the telephone line, and it is possible to reliably detect partner response detection by preventing erroneous partner response detection.

上記説明において、電話回線切断検出部１４を構成するコンパレータ１４５は、コンデンサ１４３の充電電圧を監視し、動作開始電圧と動作停止電圧の間にヒステリシスを有する手段であれば他のいかなる手段、例えばリセットＩＣ、サイリスタ、電圧監視手段などであってもよい。また、ホトカップラー１４６は、電話回線２と電話回線切断監視信号との間を絶縁する構成であれば、どのような手段例えば、リレー、フォトモスリレー、フォトトランジスタなどであってもよい。   In the above description, the comparator 145 constituting the telephone line disconnection detection unit 14 monitors the charging voltage of the capacitor 143, and any other means, for example, a reset, as long as it has a hysteresis between the operation start voltage and the operation stop voltage. It may be an IC, a thyristor, a voltage monitoring means, or the like. The photocoupler 146 may be any means, for example, a relay, a photo MOS relay, a phototransistor, etc., as long as it is configured to insulate between the telephone line 2 and the telephone line disconnection monitoring signal.
