Description

  The present invention relates to a telephone device that can automatically notify in an emergency.

In a telephone device having an emergency call function, there is a technique for automatically calling a predetermined report destination when a telephone handset remains off for a certain period of time (for example, Patent Document 1).
However, with the technique disclosed in Patent Document 1, it can be recognized that the report destination is in some abnormal state, but the content of the abnormality cannot be understood unless a call is made. For this reason, there is a drawback that the situation cannot be communicated when the caller falls down and the handset cannot be talked with the handset removed.

JP 61-1111050 A

  In order to solve the drawbacks of the prior art described above, the present invention can transmit the contents or situation of an emergency to the report destination without depending on the handset call even when the handset call is not possible. It is to provide a telephone device.

  The telephone device of the present invention is a telephone device that automatically makes a call to a destination in an emergency, and includes a hook detection means for detecting on-hook or off-hook of the own phone device, and a destination phone number registration for registering the destination phone number. Means, an automatic transmission means for automatically transmitting to the report destination registered in the report destination telephone number registration means, and an off-hook elapsed time measurement means for measuring an elapsed time since the hook detection means detects an off-hook. And when the hook detection means detects an off-hook of the apparatus and does not detect either a dial signal from the apparatus or an on-hook even after a predetermined time has elapsed, The sending means automatically sends to the callee registered in the callee telephone number registration means, and automatically sends a message to the effect that the callee has responded if the callee responds. After, start the hands-free call mode with self automatically, even after the transmission of the message, characterized by continuing the handsfree call mode.

  According to the present invention, it is possible to notify the callee that the emergency situation has occurred by simply leaving the handset such as kicking off, and also being unable to have a handset such as being in physical anomaly or robbery. However, conversation or monitor audio can be sent to the callee in the hands-free call mode.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a functional block diagram including a telephone device of the present invention. In FIG. 1, 1 is a telephone line, 2 is a DTMF (Dual-Tone Multi-Frequency) sending unit, 3 is a reporting message sending unit, 4 is a hands-free calling unit, 5 is a DTMF signal generating unit, and 6 is a calling telephone number. Registration unit, 7 is a notification message storage unit, 8 is a schedule registration unit, 9 is a control unit, 10 is an off-hook elapsed time measurement unit, 11 is a hook detection unit, 12 is a key operation detection unit, 13 is a notification function (valid / invalid) ) Switching unit, 14 is an automatic volume adjusting unit for microphone (MIC) and speaker (SP), and 15 is a handset.

  The DTMF signal transmission unit 2 transmits a DTMF signal from the own telephone device or a DTMF signal in the report destination telephone number registration unit. The report message sending unit 3 sends a report message in the report message storage unit 7 when connected to the report destination. The DTMF signal generator 5 converts the telephone number into a DTMF signal and sends it to the telephone line 1.

  The report destination telephone number registration unit 6 stores the telephone number of the emergency report destination. The report message storage unit 7 stores in advance a message to be sent to the report destination. The schedule registration unit 8 registers a report destination for each day of the week and time.

  When the off-hook elapsed time measuring unit 10 detects an off-hook of the telephone device from the hook detecting unit 11, the off-hook elapsed time measuring unit 10 starts a timer and measures the off-hook elapsed time. The hook detection unit 11 detects on-hook and off-hook of the own telephone device.

  The MIC / SP volume automatic adjustment unit 14 automatically increases the input sensitivity of the microphone and the reproduction volume of the speaker from the normal state when a call-free state is established with the report destination. The reporting function (valid / invalid) switching unit 13 enables or disables the emergency reporting function of the own telephone device.

  The key operation detection unit 12 detects a key operation of the own telephone device. The control unit 9 controls the apparatus.

FIG. 2 is a flowchart of the operation of the telephone device of the present invention. In FIG. 2, the operation of this function is started when the power is turned on (S301). When the reporting function (valid / invalid) switching unit 13 is disabled, it operates as a normal telephone device. When the reporting function is enabled, the hook detection unit 11 is operated off-hook. Wait (S302, S303).
When the hook detection unit 11 detects an off-hook operation, the off-hook elapsed time measuring unit 10 measures the time since the hook is off-hooked (S304). If a key operation from the own telephone device is detected within a certain time after the off-hook operation has been performed (YES in S305), it is determined as a normal off-hook operation, and a transition is made to a normal operation according to the key operation. Ends.

  If the hook detection unit 11 detects an on-hook within a predetermined time after being off-hooked (S306, YES), it is determined that the normal transmission is interrupted, and the flow ends.

  If there is no key operation or on-hook operation from the own telephone device within a certain time after being off-hooked, a time-out occurs (S307, YES), the process proceeds to step 308 and step 309, and the notification function is automatically activated. Thereby, even when the button operation of the own telephone device cannot be performed, it is possible to make an emergency call only by an off-hook operation.

  In Step 308 and Step 309, the schedule registration unit 8 is registered in advance with a report destination corresponding to the day of the week and time, and the control unit 9 schedules the telephone number of the report destination according to the day of the week and the time when reporting. A search is made from the registration unit 8 and is automatically transmitted (reported) to any one of the report destinations 1 to 3 according to the day of the week and the time (S310, S313, S316).

  If there is no response from the report destination after sending an automatic report (NO in S311, S314, S317), for example, retry is performed up to three times (S312, S315, S318). If there is still no response, for example, the notification retry is repeated after a predetermined time has elapsed.

  When there is a response from the report destination and a call with the report destination is started (S311, S314, S317), a pre-registered message stored in the report message storage unit 7 is first sent to the report destination (S319). ).

  Next, the own telephone device is switched to the hands-free call mode (S320). Further, after entering the hands-free call mode, the microphone input sensitivity and speaker playback volume are automatically adjusted by the MIC / SP volume automatic adjustment unit 14 (S321), and the microphone sensitivity and speaker playback volume are set to be higher than normal. Increase. As a result, even when an emergency call is made in a situation where the user cannot have a handset such as being physically abnormal or being robbed, a conversation or monitor voice can be transmitted to the report destination. After entering the hands-free call mode, when the call disconnection from the reporting destination is detected, or when a rushing person hooks on the handset of the own telephone device, this flow ends (S322).

FIG. 1 is a functional block diagram including the telephone device of the present invention. FIG. 2 is a flowchart of the operation of the telephone device of the present invention.
