The present invention relates to a telephone system, which is particularly concerned with emergency situations such as robbery in a house or physically handicapped person or a holocaust in a house without a phone in an emergency or emergency situation as an emergency transmission means. The present invention relates to an emergency call security telephone system that enables automatic telephone notification.

Unmanned telephone notification systems using telephone systems have been well known.

For example, there are known techniques such as storing telephone numbers of predetermined related places in case of fire or emergency, automatically connecting telephone lines, sending out an alarm sound, or fostering them to a voice recording apparatus such as a cassette.

However, in such a prior art, since the focus on the unmanned telephone notification function has not been advanced, a means of communication for proper use by the surrounding situation or substantial handicapped person in an emergency has been largely constrained.

For example, in the past, an emergency switch means installed in a house calls a phone number stored in the system at the time of an emergency and automatically connects a call path, and a means for notifying while recording recorded training is connected to a track at a specific place. Using the emergency switch requires a special effort due to the concealment of the switch means and at the same time increases the probability of misinformation due to mischief of the children.

In addition, they are not constrained in use because they do not have a means of automatically connecting and making phone calls without physically handicapped people, or they do not have a remote transmission / reception function by wireless means. There is a problem in gaining the confidentiality or agility of notification.

The present invention has been made to improve the problems as described above, which is a hand-free (hand-free) call function (speaker phone function) and the emergency call transmission and reception function by the remote transmission and reception means, especially in an unmanned automatic notification system in case of emergency It is to provide an emergency call security telephone system that can be expected to use the system efficiently by having a.

In order to realize the object of the above example, the present invention implements a speaker phone unit that can make a call without using a handset, and controls various messages during emergency notification, and stores a plurality of notification telephone numbers, and processes emergency notification messages while storing a plurality of notification telephone numbers. Receives and processes a system CPU that manages control, and an audio recording unit for audio recording processing of user-grown sound by the control of the system CPU, and an emergency signal connected to the system CPU and sent from a remote control transmission circuit or a manual transmission circuit. An emergency call security telephone system having a configuration including an emergency notification receiving unit.

This will be described in more detail below.

That is, the accompanying drawings are provided with respect to the telephone signal processing circuit 21, the ring tone generating circuit 22, etc., in which the emergency call security telephone logic 1 of the present invention is connected to a normal signal transformer Tr.

The emergency call security logic 1 receives the automatic transmission confirmation signal AT ₁ and the automatic reception mode signal AR ₁ of the system CPU 11 between the telephone signal processing circuit 21 and the system CPU 11 to perform a speaker phone function. When the voice is recorded under the control of the speaker phone unit 12, the keypad 15 for inputting and confirming the automatic notification telephone number to be stored in the system CPU 11, and the system CPU 11, the voice recording unit ( 13 can be transmitted to the system CPU 11 along with the lines L ₁ and L ₂ together with the voice input unit 16 for checking the recorded contents and the ring tone generating circuit 22. A ring tone detection unit 17 for providing a detection signal such as reception and the like, and an emergency notification receiving unit 18a for receiving and processing an emergency signal to the system CPU 11 by the operation of a remote control unit 18b or a manual transmitter 18c. And the other party in relation to the speakerphone unit 12 controlled by the system CPU 11 It has a structure which includes a call state detector 14 for detecting the copper been received the call is completed.

In addition, the telephone signal processing circuit 21 is a conventional HIC for a telephone, which includes a telline interface unit, a phone ringer output unit, a handset, and a dial interface unit, and the emergency call management unit 18a is a wreck band receiver. And a waveform shaping unit, and the shortwave receiver may be, for example, a narrowband FM receiver of a double super hetero nine.

At this time, the first intermediate frequency is 10.7MHZ, and the second intermediate frequency is 455KHZ, which is configured to convert the emergency notification signal sent from the relocon transmitter 18b into a low frequency signal and to provide the waveform to the system CPU 11 after waveform shaping. Have

In addition, the voice recording unit 13 is configured to include a normal ADM type voice synthesis recording IC and a data storage RAM.

Reference numerals MC and MC ₂ are first and second microphones.

The present invention of such a configuration is as follows.

That is, when a telephone call is made through the lines L ₁ and L ₂ to the emergency call crime prevention logic 1 of the present invention, a ring tone is generated in the ring tone generator circuit 22 and converted to logic through the ring tone detector 17. After that, it is provided to the system CPU (11).

In this state, when the system CPU 11 sends the automatic reception mode signal AR ₁ to the speakerphone unit 12, the speakerphone unit 12 becomes a mode that can be received through the speaker, and then automatically through the first microphone MC ₁ . Incoming call is available.

In this case, too, the body-free person can automatically receive a call without lifting the handset.

When the passage is completed, the call state detection unit 14 detects a call state from the phone signal processing circuit 21 and then automatically returns the phone line from the system CPU 11.

In this case, when the call partner hangs up the phone, a sound may be generated and received, thereby recovering the rotation.

On the other hand, in the internal memory of the system CPU 11, the automatic notification telephone number to be notified in case of emergency is normally stored by using the keypad 15. In response to the telephone number, the second microphone MC ₂ and voice recording are stored. Automatic notification messages are recorded by using the internal memory RAM of the unit 13.

At this time, the automatic notification recording means information on the system user's location, situation information (such as fire or theft or robbery), and information that requires emergency rescue. Record a message such as "You have been injured and need emergency help."

In addition, such a message can be set arbitrarily according to the number of the automatic notification telephone numbers, and in case of emergency transmission 1 to an already scheduled telephone number, the recording contents are transmitted by calling the arbitrary automatic automatic telephone numbers until all three locations are connected. In the case of emergency transmission 2, the connection process is performed until one location is connected.

Then, in order to confirm the contents of the voice recording unit 13 corresponding to the automatic notification telephone number, the contents can be known by the use of the voice input confirmation unit 16.

On the other hand, during the recording process of the voice recording unit 13, the message to be recorded is selected by the message selection switch, and when the recording button is pressed, the internal RAM is selected and the REC terminal of the voice synthesis IC is activated to enter the recording mode.

In addition, the ACL terminal of the voice synthesis IC can be activated and cleared, and recording can be started when the start terminal is activated again.

When recording starts, the recording lamp lights up at the same time, and after a predetermined time, the lamp goes off.

In the case of recording and playback, only when an emergency signal is provided to the system CPU 11 by the emergency call management unit 18a, the system CPU 11 controls the telephone preference to a call state, and then a predetermined message is output from the voice recording unit 13. The phone is taken out and notified by telephone line.

On the other hand, the emergency notification receiver 18a generates a low frequency signal (e.g., 168HZ) when the system user drives the remote controller 18b or the manual transmitter 18c when an emergency occurs, which is an emergency notification receiver 18a. If the 168HZ signal is applied to the emergency signal terminal of the system CPU 11 continuously for more than 5 times, then the connection of the telephone line, the dialing of the telephone number, the confirmation of the line connection, etc. are controlled by the interrupt program of the system CPU. Send an emergency notification message.

Here, the system CPU 11 sends the automatic dial signal ADA to the telephone signal processing circuit 21 together with the telephone line connection, and the dial signal calls the other party through the lines L ₁ and L ₂ , and then rotates with the other party. After the connection is detected, the ring tone detection unit 17 detects the rotation connection, and the system CPU 11 transmits the emergency notification message stored in the voice recording unit 13 through the telephone signal processing line 21 to the lines L ₁ and L _2. ) Will be automatically notified.

As a result, the other side can quickly and quickly prepare a countermeasure for assisting the system user with the user's emergency notification.

The present invention is equipped with a speakerphone function that enables automatic call without lifting the handset in the telephone system including the unmanned automatic notification function and the emergency notification transmission and reception function that can provide emergency notification as a remote transmission and reception means. There is a beneficial feature that increases the efficiency well.
