Description

  The present invention relates to a communication apparatus for automatically making a report to a report destination telephone by a voice message or the like.

  Conventionally, as a communication device that performs automatic notification, a voice message is transmitted when the report destination responds, and when a specific control signal transmitted from the report destination is received, it is determined that the other party has confirmed the voice message and the report is sent. If the control signal is not received and a specific control signal cannot be received, it is regarded as a non-response to the other party, and the call is continued such as calling another telephone number.

  In general, as shown in FIG. 2, when the callee detects the incoming call of the telephone and raises the handset, the caller of the telephone line in which the potential difference between the telephone lines is reversed centering on the point 200 where the potential difference between the telephone lines is zero. Since the polarity reversal 201 occurs, it is detected that the report destination has responded by the polarity reversal, and transmission of the voice message is started. Similarly, when the other party hangs up the telephone receiver, the telephone line polarity recovery 202 (which is also a kind of polarity reversal) occurs where the potential difference between the telephone lines returns to the original, centering on the point 200 where the potential difference between the telephone lines is zero. The reporting operation is terminated upon detecting that the reporting party has terminated the call due to the restoration of the polarity.

  Recently, in a telephone using an “IP telephone modem” that has begun to spread, there is a case where polarity reversal does not occur until the end of communication as shown in FIG.

  As a method not using polarity reversal, the voice message transmission timing is changed, and if it is shown in FIG. 3, the voice message is continuously transmitted immediately after dialing 301 (see, for example, Patent Document 1), or the DTMF signal from the report destination It is considered that transmission of a voice message is started by detecting (for example, see Patent Document 2).

  In the “IP phone modem”, the polarity of the telephone line is reversed by using the public telephone line without using the “IP telephone” function by dialing with a special number such as “186” at the head of the dial. However, as seen in some types of “IP telephone modems”, polarity inversion may occur as shown in FIG. 4 before the callee actually lifts the handset.

As shown in FIG. 5, as an internal configuration of an IP telephone modem, power is supplied to a telephone such as a communication device by a voltage source 501 supplied from the IP telephone modem during standby when a normal call is not being made. If the potential of the voltage source 501 is opposite to the polarity of the public telephone lines L1 and L2 when switching to the public telephone line by the switch 502, the voltage polarity of T1 and T2 connected to the telephone such as a communication device is reversed. Occurs by the occurrence of
JP-A-7-74838 JP-A-6-205128

  As in the case of the above-described conventional configuration, when detecting the response of the report destination by reversing the polarity of the telephone line, the report destination actually raises the handset as seen in some types of “IP telephone modem”. If polarity reversal occurs before, it will misrecognize that "the other party has lifted the handset" and send the voice message first.

  In addition, sending a voice message to the telephone line before the user of the report destination actually off-hooks the telephone line causes an extra signal to flow on the telephone line, and the report destination signals the start of transmission of the voice message. In order to transmit the DTMF signal, it is necessary to know what signal the reporting source is waiting for.

  SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and an object thereof is to provide a notification device that can reliably detect polarity reversal due to a response from a notification destination and can start transmitting a voice message.

  In order to solve the conventional problems, a communication terminal according to the present invention includes a line control unit that controls off-hook / on-hook control of a telephone line, a dial sending unit that dials a telephone line, the line control unit, A confirmation communication control unit that performs communication by calling a predetermined destination using the dial transmission unit, a polarity reversal detection unit that detects reversal of voltage polarity of a telephone line during communication, and the confirmation Response polarity reversal setting unit for setting the polarity reversal timing at the time of report destination response from the response notification signal from the communication control unit and the polarity reversal detection signal from the polarity reversal detection unit, and recording or synthesis after the other party's response at the dial destination And a voice transmission unit that transmits the voice message to the telephone line.

  Thus, the polarity reversal timing at the time of response of the report destination by the polarity reversal setting unit at the time of response by the signal detection signal and the polarity reversal detection signal during the communication while calling a predetermined destination by the confirmation communication control unit Therefore, at the time of subsequent notification, after dialing by the dial transmission unit, the other party's response can be detected at the polarity inversion timing at the time of response, and the voice transmission unit can notify the other party of the voice message.

  Since the reporting device of the present invention reliably detects polarity reversal due to the response of the reporting destination and starts transmitting a voice message, the reporting destination can be notified of the reporting content with certainty.

  According to a first aspect of the present invention, there is provided a line control unit that controls off-hook / on-hook control of a telephone line, a dial sending part that dials a telephone line, and a predetermined partner using the line control part and the dial transmission part. A confirmation communication control unit that performs communication by placing a telephone call first, a polarity reversal detection unit that detects reversal of the voltage polarity of the telephone line during communication, a response notification signal from the confirmation communication control unit and the polarity Response polarity reversal setting unit that sets the polarity reversal timing at the time of response from the polarity reversal detection signal from the reversal detection unit, and a voice sending unit that sends a voice message recorded or synthesized after the other party's response to the dialing destination to the telephone line By making a call to the other party predetermined by the confirmation communication control unit and performing communication, the response notification signal and the polarity inversion detection signal are used. The answer polarity reversal setting unit sets the polarity reversal timing for the response of the report destination, so after dialing by the dial sending unit at the time of subsequent notification, the other party response is detected at the polarity reversal timing at the time of response and the voice is transmitted Since the transmission of the voice message is started by the part, the report content can be surely notified to the report destination.

  A second invention includes a signal detection unit for detecting a signal from a telephone line in the first invention, and in particular, a confirmation communication control unit receives a signal predetermined by the signal detection unit, thereby receiving a signal from a communication destination. It is determined that there is a response and performs control to notify the control unit of a response notification signal and terminate communication, and the response polarity inversion setting unit is closest to the time when the response notification signal is received from the confirmation communication control unit By setting the polarity reversal of the communication destination as the polarity reversal at the time of response of the communication destination, the confirmation communication control unit can detect that the other party has responded when a predetermined signal from the communication partner is received. Because the polarity reversal detection signal with the closest timing at that time can be set by the response polarity reversal setting unit, the timing of polarity reversal when the other party can respond is set reliably It is possible.

  In the third invention, in particular, the predetermined signal of the second invention is a voice, DTMF, or modem signal. A human conversation from a communication partner, DTMF signal transmission by a general telephone, Since the confirmation communication control unit can detect that communication has been made when there is a response from a modem such as an automatic reply device, confirmation communication can be reliably performed until the other party can respond. .

  In the fourth aspect of the invention, in particular, the confirmation communication control unit of the first aspect of the invention detects that a predetermined user operation has been performed by outputting a signal flowing in the telephone line and receiving a response from the report destination. Control is performed to notify the control unit of the response notification signal and terminate the communication, and the response polarity inversion setting unit reverses the polarity at the timing closest to the time when the response notification signal is received from the confirmation communication control unit Is set as the polarity reversal when the communication destination responds, and the user confirms the modem signal, voice signal, etc. when the communication partner responds by voice output and the user performs an operation. Confirmation that the other party has responded can be detected by the communication control unit, and the polarity inversion detection signal at the closest timing at that time can be set by the response polarity inversion setting unit. The timing of the rolling can be reliably set.

  In the fifth invention, in particular, the predetermined user operation of the fourth invention is any one of a button or touch panel operation, a predetermined voice input operation, or a combination thereof. Confirmation communication control when the user confirms the modem signal or voice signal when the other party responds by voice output and the user performs either a button or touch panel operation, a predetermined voice input operation, or a combination thereof Since the part can detect that the other party has responded, the confirmation communication can be performed until the other party can surely respond.

  A sixth invention is a program that causes a computer to execute all or part of the functions of any one of the first to fifth inventions, thereby changing the program during operation by downloading on a recording medium or a communication line. Since it can be added, it can cope with new specification changes.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the present embodiment.

(Embodiment)
FIG. 1 shows a block configuration diagram of a communication apparatus 1 according to an embodiment of the present invention.

  In FIG. 1, the line control unit 101 controls off-hook / on-hook of the telephone line 3, the dial sending part 102 dials the telephone line 3, and the voice sending part 103 records or synthesizes after answering the other party of the dial destination. Is sent to the telephone line 3, the signal detection unit 104 detects the reception of a predetermined signal from the telephone line 3, and the polarity reversal detection unit 105 detects the polarity reversal of the telephone line 3 and performs control. The unit 106 controls each unit and detects the signal of the sensor 2 to perform a notification operation, and the communication confirmation button 107 is an operation button used at the time of installation.

  In the internal configuration of the control unit 106, the confirmation communication control unit 108 performs communication by calling a predetermined destination using the line control unit 101 or the dial transmission unit 102, and the number conversion unit 109 starts from the start of communication. When the polarity reversal detection unit 105 does not detect polarity reversal by the end, the telephone number to be dialed in the future is set with a predetermined number before dialing, and the time counting unit 110 starts / ends the time count as a timer. The response polarity inversion setting unit 111 sets the polarity inversion timing when the communication destination responds.

  If the number conversion unit 109 does not detect polarity reversal, the predetermined number added before the telephone number to be dialed in the future is “186”, and the public telephone line is always used for communication via the “IP telephone modem”. Make a call.

  The sensor 2 notifies the communication device 1 such as an emergency call button, a window / door opening / closing sensor, a human sensor for detecting infrared rays or movement, a gas leak sensor, a gas meter, a failure sensor for facility equipment, and the like. .

  The operation and action of the communication device 1 configured as described above will be described below with reference to FIGS.

  When installing the communication device 1, the installer connects the communication device 1 to the telephone line 3 and presses the communication confirmation button 107.

  When the control unit 106 detects that the communication confirmation button 107 has been pressed (S601), the control unit 106 communicates with the communication confirmation center that is a communication destination predetermined by the confirmation communication control unit 108 (S602). The confirmation communication control unit 108 makes a call by controlling the line control unit 101 and the dial sending unit 102 to dial the communication confirmation center (S603). Since the telephone number of the communication confirmation center is a predetermined communication destination, the telephone number stored in the confirmation communication control unit 108 as a predetermined telephone number is used.

  When receiving a call, the communication confirmation center off-hooks the telephone line and sends a 1400 Hz sine wave signal, which is a kind of audio signal, to the telephone line.

  After dialing the communication confirmation center, the confirmation communication control unit 108 sends a response notification signal to the control unit 106 (S607) when the signal detection unit 104 is notified of signal detection at 1400 Hz, which is a predetermined signal (S606). ), The line control unit 101 is controlled to end the communication.

  The confirmation communication control unit 108 determines whether the polarity reversal of the telephone line 3 has occurred between the start and end of communication with the communication confirmation center by the polarity reversal detection unit 105 (S604), and does not perform the polarity reversal. In the case (S608), the number conversion unit 109 is set to be dialed by adding "186" before the telephone number to be dialed in the future (S609), and the communication to the communication center is performed again.

  Further, when the control unit 106 receives the response notification signal from the confirmation communication control unit 108 (S610), the polarity inversion detection is performed until the point of polarity inversion closest to the timing at which the response notification signal is received, that is, until the response notification signal is received. The number of detections of polarity reversal notified from the unit 105 is set in the response polarity reversal setting unit 111 (S611). For example, when the telephone line voltage changes as shown in FIG. 4, two polarity reversals of the first polarity reversal 401 and the second polarity reversal 201 occur until the response notification signal 403 is received. The response polarity reversal setting unit 111 is set to “twice”. Thereby, it can be seen that the time when the second polarity reversal occurs is the timing when the communication destination responds.

  After that, when receiving the report factor signal from the sensor 2, the control unit 106 instructs the line control unit 101 to off-hook the telephone line 3 as a call request (S701), and sends a notification destination to the dial transmission unit 102, as in the prior art. And a dial signal is transmitted to the telephone line 3 (S702).

  Next, the control unit 106 instructs the timing unit 110 to start timing of the first timer (T1) (S703), and the polarity is inverted by the number of times set in the response polarity inversion setting unit 111 when the destination telephone goes off-hook. Since the polarity reversal detection signal is received from the detecting unit 105 (S705), the voice sending unit 103 is instructed to send a voice message to the telephone line 3 (S706), and the voice sending unit 103 stops the message. The voice message is repeated until it is instructed to start transmission to the telephone line 3, and at the same time, the time measuring unit 110 is instructed to stop timing (S707) of the first timer (T1) and to start timing of the second timer (T2). (S708).

  When the receiver is off-hooked to the incoming call from the communication device 1, the report destination telephone can hear the recorded or synthesized voice message from the communication device 1 via the telephone line 3. The contents of the voice message are the contents of the cause of the report (for example, intruder report, gas leak report, emergency call report, etc.) and the confirmation operation (for example, “Please press' #” button for confirmation ”). The operator operates the buttons on the telephone according to the voice message repeatedly heard.

  The signal detection unit 104 analyzes the signal received from the telephone line 3, converts it into a code, and notifies the control unit 106. When the operator of the destination telephone presses the '#' button on the telephone, Since the “#” signal is received by the communication apparatus 1 as a DTMF (Dual Tone Multi Frequency) signal via the line 3, the signal detection unit 104 notifies the control unit 106 of “#” reception (S 709). The unit 106 instructs the voice sending unit 103 to stop sending the first message (S710), and instructs the line control unit 101 to turn on the telephone line 3 as a disconnection request, thereby terminating the notification (S711).

  Also, in the above flow, when the destination is not present or the telephone is busy and the telephone is not connected, the first timer (with the number of polarity reversals detected on the telephone line 3 being less than the number set in the response polarity reversal setting unit 111) Since T1) times out (S712), when the control unit 106 is notified of the T1 timeout from the time measuring unit 110, the control unit 106 instructs the line control unit 101 to turn on the telephone line 3 as a disconnection request (S713). ). Further, as the redial process, the user is surely notified by dialing another destination or redialing to the same destination at a later time (S714).

  Furthermore, if the voice message cannot be heard even if the report destination responds, the second timer (T2) times out without receiving the instructed signal (S715), so T2 from the timer 110 A time-out notification is sent to the control unit 106, and redial processing is performed in the same manner as the time-out of the first timer (S717).

  With the above operation, even when the communication apparatus 1 is connected to an “IP telephone modem” in which the polarity inversion of the telephone line 3 does not occur, the number conversion unit 109 adds “186” to the head of the destination telephone number. When the other party responds by connecting to a public telephone line without performing an IP phone call via the Internet, the telephone line 3 can be operated with polarity reversal, and even when there are multiple polarity reversals, the response polarity Since the polarity reversal when the other party responds can be reliably detected by setting the number of times of the reversal setting unit 111, the call destination telephone can hear the voice message from the beginning when it is off-hook.

  In this embodiment, the signal transmitted from the confirmation communication center is a 1400 Hz sine wave. However, if a DTMF signal or a modulated modem signal is used, the signal can be detected by a commercially available receiver IC. The part can be configured easily.

  Further, if the signal sent from the confirmation communication center is a voice message such as “please press the communication confirmation button” and the speaker that can output the signal flowing through the telephone line 3 is attached to the communication device 1, Confirming the connection to the confirmation communication center, and pressing the communication confirmation button as a predetermined user operation to notify the control unit of the response notification signal and terminate the communication, the signal detection circuit There is no need to provide it.

  In addition to pressing the button, the operation method may be an interface attached to the communication apparatus 1. For example, the touch panel is pressed, or the button and the touch panel are pressed simultaneously or in a predetermined order. It can also be done.

  Further, in this embodiment, the communication is terminated when the confirmation signal “#” is pressed in the notification destination telephone, but the signal detection unit 104 receives it by pressing a predetermined button from the notification destination telephone. Then, if the control unit 106 determines and performs a predetermined operation (for example, voice transmission of data accumulated in the control unit 106 or buzzer sound transmission from the communication device 1), a signal indicating the end of communication The communication device 1 can be controlled from the telephone of the report destination until it is detected.

  In the present embodiment, the predetermined number added before the telephone number to be dialed in the future when the polarity conversion unit 109 does not detect polarity reversal is “186”, but “184” or “0000” may also be used. Similar to the present embodiment, by making a call through a public telephone line without using the “IP telephone” function, the polarity of the telephone line can be reversed when the report destination responds.

  In the present embodiment, the number conversion unit 109 is used to add a predetermined number to be added before the telephone number to be dialed in the future when the telephone line does not detect polarity reversal. If you want to dial with a number (for example, “186”, “184”, “0000”, etc.), even if you are connected to an “IP phone modem”, you will not be able to use the “IP phone” function. By making a call, the polarity of the telephone line can be reversed at the time when the callee answers.

  Moreover, it is realizable using a computer by implement | achieving all or one part of each function of these communication apparatuses 1 with a program or data. Also, by using a recording medium that records the program and data, it is easy to write software into the control memory of a general-purpose microcomputer or move data to another terminal. It is possible to cope with new specification changes by changing or adding programs during operation by downloading.

  Since the communication device of the present invention makes a notification when a notification occurrence event occurs and reliably notifies the content to the notification destination phone as a voice message, the emergency notification device, the security sensor abnormality notification or the sensor information change notification, It can also be used for applications such as centralized monitoring of equipment and facilities.
