Description

  The present invention relates to a method for making an emergency call by remote operation using a telephone line.

  Various notification systems have been developed that are installed in the house and notify the outside using a telephone line when an emergency situation is detected by a sensor or when an emergency notification button is operated. The emergency includes emergency situations such as illegal intruders, fires, etc., or sudden changes in conditions such as those who are being treated at home or elderly people who need nursing care. In addition, these notification systems usually have a function that a user externally activates the notification system by telephone and collects predetermined data obtained from, for example, a monitoring camera or a nurse in need from the notification system. ing. Further, when the above-described notification system is installed in a house, it is usually connected to a telephone line to which a communication device such as an existing telephone and / or a facsimile device is connected together with these communication devices.

  Conventionally, for example, Japanese Patent Laid-Open No. 2002-27131 (hereinafter referred to as Patent Document 1) is disclosed as a technique for calling a notification system from the outside using a telephone line and taking out the notification data. With this technology, even when connected to the same telephone line as other communication devices such as telephones and facsimile devices, it is possible to selectively perform an incoming operation while ensuring the operation of these communication devices, and Various functions can be activated.

  The notification device disclosed in Patent Document 1 has a so-called “call abandonment” in which a telephone line is disconnected immediately after ringing by a paging signal within a predetermined number of times when an incoming call is received on the telephone line; After this call abandonment, a normal incoming operation to the reporting device is started on the condition that both “re-incoming” within a preset reference time and satisfaction of both.

  For example, in the emergency call device 100 shown in FIG. 4, the call determination control unit 200 counts the call signal received for an incoming call by the call abandonment detection timer 103 at the time of the incoming call, and transmits the telephone line before counting twice. The call abandonment detection 201 is activated when a disconnection signal is received from the side. In the call determination control unit 200, when the function of the call abandonment detection 201 activates the continuous incoming call detection timer 104 and receives an incoming call within a predetermined time, the function of the continuous incoming call detection 202 detects a re-incoming call. The report determination control unit 200 causes the report control unit 101 to start predetermined report control via the detected telephone line connection control unit 102 when detecting both call abandonment and re-incoming call.

  With this configuration, when the ringing operation is continuously performed without disconnecting the telephone line halfway from the first incoming call, not only the answering machine function on the telephone, the automatic switching function of the facsimile apparatus, etc. can be operated, The reporting device can be activated in a short time.

JP 2002-27131 A

  In the above-described prior art, by setting the predetermined time of the continuous incoming call detection timer to a relatively short time such as several tens of seconds, a person other than the user who abandoned the call accidentally calls from the outside within this predetermined time. It is said that the possibility of making a call can be kept sufficiently low to effectively prevent the notification device from shifting to an incoming call operation caused by a call other than the user. However, if the incoming call cannot be detected due to traffic congestion on the exchange network operated by the telecommunications carrier, or if another incoming call occurs within a relatively short set time, the reporting device will malfunction. There is no opportunity. In addition, a re-incoming call for one call abandonment activates the notification device, but even in the case of a normal call, there may be a user who makes a re-call after abandoning the call unconsciously.

  Further, in the above-described prior art, since the notification data of the notification device is transmitted to the caller, the data is listened / recorded by the caller's telephone or received by the notification receiver on the caller side. On the other hand, it is assumed that the home caregiver is alone and cannot operate the emergency call device due to sudden illness or the like. In this case, an emergency call cannot be made by operating a push button including a wireless remote switch. In such a state, the party cannot answer the incoming call.

  As mentioned above, when starting an emergency call system connected to this telephone line using a telephone line from the outside, the malfunction that starts the emergency call device due to an incoming call from a person other than the user of this emergency call system is I can't escape.

  The emergency call system according to the present invention is connected in advance to a telephone line of a telecommunications carrier, and is set in advance after a call abandoned call that arrives at the telephone line and is disconnected within a predetermined time, and after the call abandoned call. The present invention relates to an emergency notification device that starts a notification operation of a device with a notification start condition that both a re-incoming call and a re-incoming call within a reference time are satisfied.

  In order to solve the above problems, one emergency call system according to the present invention is provided with a call mode setting button. That is, the emergency call system according to the present invention is characterized in that the emergency call device can be activated from the telephone line only when the report mode setting button is operated.

  The other is to confirm the re-incoming call using a telephone number and a caller ID notification service given by the telecommunications carrier. That is, the emergency call system according to the present invention records a caller number at the time of call abandonment incoming call, checks the caller number at the incoming call after the call abandonment incoming call, confirms the re-incoming call, and further continues multiple times. When a predetermined number of call abandoned calls and re-incoming calls are counted and a predetermined number is reached, a predetermined report destination is called.

  By providing the notification mode setting button and switching the notification mode, the predetermined time for detecting the call abandonment incoming call can be set to an appropriate long time. In addition, the emergency call device notifies the caller that the call instruction has been received, and then the emergency call device calls a predetermined call destination via the telephone line to send the call data to the call destination. Can be sent out.

  Furthermore, the emergency call system according to the present invention records and verifies the caller number at the time of call abandonment incoming call, confirms continuous re-incoming calls, and calls a predetermined call destination when a predetermined number is reached. As a result, the use of this system can be limited and reliable reporting can be made to the reporting destination. That is, it is possible to avoid malfunctions from other than the user.

  In the present invention, when an emergency call device call is received from the outside using a telephone line when the notification mode setting button is provided and operated, the notification operation of the emergency call device is started. The chance of malfunctioning the emergency call device due to an incoming call from can be reduced.

  In addition, since the incoming call is confirmed by the caller ID collation match, and a plurality of consecutive matches are determined, the emergency call device call determination can be ensured and the incoming call from a user other than the user Thus, it is possible to reliably avoid an opportunity to cause the emergency call device to malfunction. Furthermore, the combination of the notification mode setting button and the caller number verification for a plurality of consecutive times is effective in further preventing malfunctions when calling the emergency notification device.

  In addition, the switching setting with the notification mode setting button can set the predetermined time for detecting abandoned incoming calls to an appropriate long time, so that the home caregiver alone can not operate the emergency call device due to sudden illness etc. However, no response at the emergency call device can be detected. Therefore, an emergency call can be reliably delivered to a predetermined report destination.

  In addition, the emergency call device notifies the caller that the call instruction has been received, and then the emergency call device calls a predetermined call destination via the telephone line to send the call data to the call destination. Can be sent out. With this configuration, the emergency call system according to the present invention is capable of setting an appropriate predetermined time for detecting a call abandonment incoming call even if the home caregiver is alone and cannot operate the emergency call device due to sudden illness, etc. Thus, it is possible not only to avoid unnecessary long-time calling, but also to reliably notify the callee by a predetermined call abandonment procedure.

It is explanatory drawing which shows one form of embodiment of the emergency call apparatus which concerns on Example 1 of this invention with a functional block. It is explanatory drawing which shows the outline of the operation | movement procedure of the emergency call apparatus in FIG. It is explanatory drawing which shows the detailed operation | movement procedure of the emergency call apparatus in FIG. It is explanatory drawing which shows Example 3 following FIG. 3A of the detailed operation | movement procedure of the emergency call apparatus in FIG. 1 with a flowchart. It is explanatory drawing which shows an example which concerns on the conventional emergency call apparatus with a functional block.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  The emergency call system according to the present invention is connected to a telephone line of a telecommunications carrier, receives a call to the telephone line and disconnects the telephone line within a predetermined time, and a preset criterion after the call abandonment is received. The present invention relates to an emergency notification device that starts a notification operation with a notification start condition that both a re-incoming call that has been received again in time is satisfied.

  The main object of the present invention is to reduce the chance of malfunctioning an emergency call device due to an incoming call from a person other than the user.

  Therefore, the emergency call system according to the present invention includes a notification mode setting button, and when the notification mode setting button is operated, a predetermined time for call abandonment incoming call detection can be set to an appropriate long time in advance. Accept a re-incoming call that has been confirmed to be unanswered. Furthermore, the emergency call system notifies the caller that the call instruction has been received from the emergency call device, and calls the predetermined call destination via the telephone line from the emergency call device to send the notification data. It is characterized by being sent out first.

  Furthermore, the basis is to make it possible to avoid erroneous connections from other than the user. Therefore, in the emergency call system according to the present invention, the caller number accepted when the call is abandoned is stored, and the incoming call is confirmed by the coincidence of the caller number. Furthermore, the emergency call device is activated for the first time when the call re-incoming call is repeated a plurality of times.

  With the configuration described above, it is possible to provide an emergency call system capable of reliably reporting to a predetermined report destination even in a situation where home caregivers cannot operate the emergency call device alone due to a sudden illness or the like.

  In the following embodiments, an emergency call system will be described with reference to a functional block diagram and a flowchart. However, changes such as distribution / merging of block functions or replacement of procedures are free as long as they satisfy the gist of the present invention, the functions described in the specification and described in the claims, and the present invention is limited by the following description. Is not to be done.

  The emergency call system according to the first embodiment will be described with reference to FIG.

  The emergency call device 10 in the illustrated emergency call system connects a telephone line of a telecommunications carrier to one side and a telephone 30 to the other side. The emergency notification device 10 includes an alarm sensor 11, a notification destination memory 12, a notification data transmission unit 13, a caller number memory 14, a call abandonment detection timer 15, a re-arrival determination timer 16, a continuous reception counter 17, and a notification mode setting button 18. , A message transmission device 19, a notification control unit 20, a telephone line connection control unit 21, and a notification determination control unit 22. The report determination control unit 22 has functions of caller number verification 23, call abandonment detection 24, re-incoming call determination 25, and emergency call determination 26.

  The alarm sensor 11 includes a sensor that detects an abnormality or anomaly in a house, a sick person, etc., and notifies the information data to the report data sending unit 13 via the report control unit 20, and a button for calling a report destination. The report destination memory 12 stores in advance a telephone number or the like as report destination information. The report data sending unit 13 receives report data to be reported to the report destination from, for example, the alarm sensor 11 and records it as needed. The report data recorded by the control of the report control unit 20 is sent to the telephone line via the telephone line connection control unit 21. Send it out.

  The caller number memory 14 receives the control of the report determination control unit 22 and records the caller number to be accepted each time an incoming call is received from the telephone line. The call abandonment detection timer 15 measures a predetermined time under the control of the notification determination control unit 22, and the notification determination control unit 22 detects a call abandonment reception when a disconnection signal is received within that time. The predetermined time may be counted as a ringing signal accepted for incoming from the telephone line. The call abandonment detection timer 15 can change the set time depending on whether or not the notification mode setting button 18 is operated. When the notification mode setting button 18 is operated, it takes a relatively long time to detect no response, but when there is no operation, a response in a short time is expected from an incoming call. Is done.

  The re-arrival determination timer 16 also measures the predetermined time under the control of the notification determination control unit 22, and the notification determination control unit 22 continuously receives an incoming call within a reference time set in a relatively short time after the call abandonment reception. It is determined that the incoming call has been received again. This reference time is preferably set in consideration of traffic congestion of the telephone network through which the telephone line passes. The continuous reception counter 17 measures the number when the call abandonment incoming call and the re-incoming call are continued under the control of the notification determination control unit 22.

  The report mode setting button 18 is a main feature of the present invention, and can be set to a report mode in which a report destination is called from a telephone line by operating when the user is absent. By this button operation, even when a home care worker is alone and has a sudden illness or the like, it is possible to detect an abnormality by calling from an outside line and notify a predetermined report destination even when the push button operation for operating the emergency call device cannot be performed.

  When the notification mode setting button 18 is used to set the notification mode, the message sending device 19 sends a voice message, a predetermined signal, etc. to the telephone line indicating that the emergency notification device 10 has been activated to the caller when an emergency call is determined. Send to the caller side and notify.

  The report control unit 20 has a conventional report function for reporting destinations under various conditions, and from the report data transmission unit 13 through the telephone line connection control unit 21 or directly under the control of the report determination control unit 22. Predetermined report data is sent to the report destination via a telephone line.

  The telephone line connection control unit 21 normally connects the telephone line and the telephone 30 directly and monitors the line state. The telephone line connection control unit 21 receives control from the notification control unit 20 or the notification determination control unit 22 to connect the notification data transmission unit 13, the message transmission device 19, or the telephone 30 to the telephone line, and to connect the telephone line. The emergency call device 10 or the telephone 30 can be connected to a preset call destination by making a call with a dial of the call destination stored in the call destination memory 12.

  When the notification mode setting button 18 is operated, the notification determination control unit 22 has functions of caller number verification 23, call abandonment detection 24, repeat incoming call determination 25, and emergency call determination 26, and an emergency call is generated. Is determined, and the notification control unit 20 is driven via the telephone line connection control unit 21 to execute a predetermined procedure.

  The caller number collation 23 stores the caller number in the caller number memory 14 when receiving an incoming call. If the caller number is already stored, the caller number collation 23 compares the caller number and notifies the incoming call determination 25 with a match. Then, the memory is updated. The call abandonment detection 24 starts the call abandonment detection timer 15 upon arrival and detects call abandonment that is disconnected within a predetermined time period, while notifying the telephone line connection control unit 21 of the arrival when the time limit is reached. Transition to a predetermined operation. At the time when the notification mode setting button 18 is operated, the ringing time by at least several ringing signals is set so as to be able to detect an unanswerable state for an incoming call. When this time limit is reached, for example, a telephone line release process is executed following a short answering service after an automatic response.

  The re-incoming call determination 25 starts the re-incoming call determination timer 16 when a call abandonment is detected, and determines that it is a re-incoming call when the caller number is the same as that stored in the caller number memory 14 for an incoming call within a predetermined reference time. When the time is reached, the connected telephone line is released. The emergency call determination 26 increments the count of the continuous reception counter 17 by one every time it is determined that the re-incoming call is determined by the re-incoming call determination 25, and determines that it is an emergency call when the predetermined number is reached, thereby determining the telephone line connection control unit 21. And the emergency call device 10 starts a predetermined emergency call process. There is no need to set an extremely short time because the caller ID is verified in the re-arrival determination.

  That is, the notification determination control unit 22 notifies the notification control unit 20 of the emergency notification determination via the telephone line connection control unit 21, so that the notification control unit 20 connects the message sending device 19 to the telephone line, for example, an emergency notification device. Is notified by voice from the message sending device 19. The report control unit 20 reads out the report destination dial number from the report destination memory 12 after repeatedly sending the message, for example, and then calls the report destination by automatically dialing after releasing the telephone line connected to the caller. The notification data transmission unit 13 is connected to the telephone line to transmit predetermined notification data. In this case, in addition to the data recorded in the notification data sending unit 13, a message indicating that an emergency has been found and notified from the outside is added to the notification data.

  Next, the main functions of the present invention will be described as a second embodiment with reference to FIG.

  That is, the notification mode setting button 18 has already been operated and is set to the notification mode (step S1), and the caller number memory 14, the call abandonment detection timer 15, the re-incoming call determination timer 16, and the continuous reception counter 17 are initialized ( The procedure starts with the procedure S2) being performed.

  If there is an incoming call (YES in step S3), the notification determination control unit 22 accepts the caller number and records it in the caller number memory 14, but collates it (step S4) if it is already stored. Then, the notification determination control unit 22 determines that the incoming call is re-incoming as the same sender number (YES in step S5) in the case of matching, and measures the number of times (step S6).

  When the procedure S5 is “NO” and the caller number is not the same, or after the procedure S6, when the number of times of measurement has not reached the predetermined value (NO in the procedure S7), the report determination control unit 22 abandons the call as before. Is detected (YES in step S8) and it is determined that the incoming call is a re-incoming call (YES in step S9), the process returns to step S3 and waits for the next incoming call.

  When the above step S7 is “YES” and the number of measurements reaches a predetermined value, the notification determination control unit 22 causes the notification control unit 20 to activate the notification control via the telephone line connection control unit 21, and the caller ID The memory 14, call abandonment detection timer 15, re-arrival determination timer 16, and continuous reception counter 17 are initialized (step S10). The notification control unit 20 instructs the telephone line connection control unit 21 to connect the message sending device 19 to the telephone line and, for example, sends a voice message “Starting the notification device and reporting to the report destination” to the caller number. After the transmission to the original, the telephone line is released, the report destination is called by automatic dialing, and the report data sending unit 13 is switched to this telephone line (step S11). As a result, the caller can know that the emergency call device has been activated by this call.

  When the above steps S8 and S9 are “NO” and either the call abandonment detection or the reincoming call determination cannot be performed, the emergency call device 10 has the caller number memory 14, the call abandonment detection timer 15, the reincoming call determination timer 16, Then, the continuous reception counter 17 is initialized and restored (procedure S12).

  Next, referring to the flowchart of FIGS. 3A and 3B together with the block diagram of FIG. 1, one embodiment of the operation procedure of the emergency notification device 10 will be described in detail as a third embodiment.

  When the emergency call device 10 accepts an incoming call (YES in step S21), the call determination control unit 22 sets the caller number when the call mode is set by operating the call mode setting button 18 (YES in step S22). Accept and record in caller number memory 14. However, if it is already stored, the caller number collation 23 collates the caller number between acceptance and recording (step S23). Then, the notification determination control unit 22 adds one continuous reception counter 17 (step S25) as continuous reception of the same caller number (YES in step S24) in the case of coincidence, and the emergency notification determination 26 measures the number of times. To do.

  When the emergency call determination 26 determines that the measured value has reached a predetermined value (YES in step S26), the notification determination control unit 22 causes the notification control unit 20 to activate notification control via the telephone line connection control unit 21, The caller number memory 14, the call abandonment detection timer 15, the re-incoming call determination timer 16, and the continuous reception counter 17 are initialized (step S27). The notification control unit 20 instructs the telephone line connection control unit 21 to connect the message sending device 19 to the telephone line, and, for example, to the originator of the caller, for example, “Start the reporting device and report to the report destination”. A message is transmitted (step S28). Since the call control unit 20 subsequently accepts the disconnection from the caller side, the telephone line is released (step S29), the dialed number of the callee is read from the callee memory 12, and the callee is called by automatic dialing. . The report control unit 20 connects the report data sending unit 13 to this telephone line in response to the report destination and transmits the report data (step S30).

  When the above steps S24 and S26 are “NO” and the caller numbers do not match or the measured value does not reach the predetermined value, the call abandonment detection 24 of the notification determination control unit 22 starts the measurement at the call abandonment detection timer 15 (step S31). ) Then, the call abandonment detection 24 detects that there is a disconnection from the calling side (YES in step S33) as a call abandonment incoming before the predetermined value is reached by the call abandonment detection timer 15 (NO in step S32). The call abandonment detection timer 15 in the operation of the notification mode setting button 18 needs an appropriate length of time for ringing, for example, three or four ringtones in order to detect a state where it cannot respond. In addition, it is possible to take measures to prevent false notifications due to continuous incomings with extremely short incoming times due to one-off or mischief.

  The notification determination control unit 22 activates the re-arrival determination timer 16 by the re-incoming determination 25 upon detection of the call abandoned incoming call, starts measurement, and initializes the call abandonment detection timer 15 (step S34). When the re-arrival determination timer 16 has not reached the predetermined value (NO in step S35) and there is an incoming call (YES in step S36), the re-incoming determination timer 16 determines that the re-incoming determination 25 continues and initializes the re-incoming determination timer 16 ( Then, the procedure returns to the procedure S23 and the procedure for determining continuous reception is repeated.

  When step S22 is “NO” and the notification mode is not set, various known incoming calls (step S40) are executed. When the above step S32 is “YES” and exceeds a predetermined value of the call abandonment detection timer 15, the call abandonment detection timer 15 is initialized as an unacceptable state such as absence (step S41), and a predetermined answering machine answering or the like is performed. Incoming processing (step S42) is executed. If step S35 is “YES” and the predetermined value of the re-arrival determination timer 16 has been reached, the re-incoming determination timer 16 is initialized (step S43) and a predetermined release process (step S44) is executed.

  In the above explanation, since one telephone line is connected and re-incoming to the same telephone line is targeted, it is necessary to change the connection for emergency calls, but if another telephone line can be connected, It is possible to adopt a procedure for calling a report destination without waiting for disconnection from the user. In this case, the report data can be sent to the caller.

  In the present invention, by providing a notification mode setting button, system activation from the telephone line can be limited to the operation of the button, and the availability of notification data can be manually limited. In addition, the verification of the caller ID and the determination based on the number of repetitions can almost eliminate the erroneous start of the system. In this way, it can be used when receiving information or data from the system by using the telephone line of the telecommunications carrier to receive the incoming call. Furthermore, using both together improves the certainty.

  In addition, the system can be used for a transfer system of an exchange apparatus having a plurality of telephone lines by enabling dialing to a predetermined reporting destination and switching the connection destination by starting the system from the telephone line. Furthermore, when the reporting device is connected to a telephone exchange device having a plurality of external lines, the reporting device user can make a call by sending from the outside, and the caller can set the forwarding destination in advance to the forwarding device, The reporting device can be used as a transfer device.

  As mentioned above, although this invention was demonstrated in detail with reference to embodiment and an Example, this invention is not limited to the said embodiment and Example. Various changes that can be understood by those skilled in the art can be made to the configuration and details of the present invention within the scope of the present invention.
