EXAMPLE

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

1 shows a control box and a block diagram according to the present invention. First, when power is supplied through the DC-adapter 21 of the power supply unit B, the predetermined voltage V _DD is constant by the voltage regulator 22. And then applied to one end of the system switch SW1, such a predetermined voltage V _DD charges the rechargeable battery 23 so that power can be supplied at the time of power failure. The battery voltage checker 24 checks the voltage of the rechargeable battery 23 and when the voltage is low, turns on the light emitting diode LED3 to display it. Subsequently, when the system switch SW1 is turned on, the light emitting diode LED1 indicating that the system is turned on by the voltage V _DD is turned on and the clock oscillator 1 is enabled, and the detection delay timer 3 ) Is set to an initial state, and when the clock oscillator 1 is operated, the clock holder 2 is enabled to apply a clock signal to the detection delay timer 3. At the same time, the system on driver 19 is driven by the voltage V _DD to output a high signal indicating that the system is turned on to the dial repeater unit E through the system on signal terminal T1. The system-on driver 19 operates the relay driver 18 to block the connection between the telephone terminal T3 and the extension telephone terminal T5, which is used when the intruder puts down the handset of the extension telephone from the telephone. Even if off-hook, the dial tone and outgoing message cannot be heard, and the main telephone can dial even when the telephone line of the extension telephone is disconnected.

At this time, prior to turning on the system, the operation time of the detection delay timer 3, the operation delay timer 5 and the siren time adjustment timer 7 is set by the switches SW2, SW3, and SW4. If (SW2) is set at the position of 30 seconds, even if the system is turned on, the sensing operation is started by the detection delay timer 3 after 30 seconds so that the system operator is not detected, and the switch SW3 is set for a predetermined time, for example, 7 seconds. In the position, the operation delay timer 5 causes the dialing to be made to the emergency contact point 7 seconds after the deceleration signal from the sensor is input, and the siren is operated while operating the alarm lamp. This is to give the system operator some time to turn off the system when returning home. The switch SW4 is used to set the alarm lamp and the operating time of the siren, for example, 30 seconds, 4 minutes, or infinity, which are controlled by the siren time adjustment timer 7.

Here, when the switch SW2 is set to the position of 30 seconds, the system is turned on, for example, the sensor latch circuit 8 starts after 30 seconds as the sensing operation is delayed by the sensing delay timer 3 for 30 seconds. Is enabled and a sensing signal is input from the sensor S1. When the sensing signal is input, the sensor latch circuit 8 enables the clock holder 4 to apply a clock signal to the operation delay timer 5. Will be done. Subsequently, the output of the detection signal is delayed by the operation delay timer 5 for a predetermined time, for example, 7 seconds, and after 7 seconds, the detection signal is output to enable the clock holder 6 and enable the enabled clock holder ( The signal is output from 6) to drive the relay driver 10 and the power driver 11. The relay driver 10 and the power driver 11 are driven to operate the siren oscillation amplifier 12 to operate the speaker ( The siren sounds through 13) and the alarm lamp L is activated by the relay driver 10 at the same time. At this time, when a predetermined time set in the siren time adjustment timer 7, for example, 30 seconds has elapsed, the timer 7 disables the sensor latch circuit 9 to output a signal from the clock holder 6 to generate a siren. And alarms will stop. If the time of the timer 7 is set to infinity, the operation of the siren and the alarm can be stopped by turning off the system switch SW1.

On the other hand, the detection signal from the sensor (S1) is delayed for 7 seconds by the operation delay timer (5), and then is output to the dial repeater unit (E) shown in FIG. 2 through the detection signal output terminal (T2), In the telephone unit C, when a signal is input from the dialy Peter unit E, automatic dialing is performed to transmit a voice message.

The emergency switch SW5 is artificially operated regardless of whether the system switch SW1 is turned on or off. When the emergency switch SW5 is turned on, the latch circuit 14 is enabled to power the driver 17. Outputs a signal to the power driver 17, and receives the signal to drive the relay driver 18 to cut off the connection between the telephone terminal T3 and the extension telephone terminal T5 and at the same time the system driver 19), a high level system on signal is output to the sheath on signal terminal T1. When the signal indicating that the emergency switch SW5 is closed is output from the latch circuit 14 to the detection signal output terminal T2, the telephone unit C shown in FIG. 2 detects the detection signal from the sensor S1. As is entered, the voice mail is automatically sent to the emergency contact. On the other hand, the signal from the latch circuit 14 is also applied to the delay timer 15 and delayed for a predetermined time, for example, 5 seconds, and then the relay driver 10 and the power driver 11 are driven in the same manner as described above. L) and siren are activated. At this time, setting the delay time for a predetermined time, for example, 5 seconds, is to prevent the accidental action of the intruder when the alarm light and the siren are operated as soon as the system operator turns on the emergency switch SW5. On the other hand, when the emergency switch SW5 is turned on, the system switch SW1 is reset to the off position when the switch is in the on position, and to the on position when the emergency switch SW5 is in the on position.

In addition, the sensors 53 and 54 are vibration detection sensors or contact detection sensors installed in window glass or the like instead of an entrance. For example, sensors that allow an overcurrent to flow when the window glass is broken are used. The detection signal does not require a detection delay time or an operation delay time, and operates only when the system switch SW1 is on. If a detection signal is input from the sensor S3 S4, the light emitting diode (LED2) is detected by the overcurrent detector 16. Lights up and the detection signal is input to the sensor latch circuit 9 to operate the alarm lamp L and the siren for a predetermined time set in the timer 7. At the same time, the sensing signal is output to the sensing signal output terminal T2, and the telephone unit C shown in FIG. 2 is automatically dialed as described above, and the voice message is transmitted.

In addition, the sensor (S2) by turning on the switch (SW6) when using only the function of the phone without turning the system on, the function of the doorbell to detect the ringer and ring the bell. When detected, the doorbell circuit 20 is driven to output the buzzer sound twice, for example, "ding-dong".

Next, FIG. 2 is a block diagram of a telephone according to the present invention. First, when a ringer signal is input through a telephone line T4, the ringer 25 is operated by the ringer signal to ring a signal to a speaker (not shown). When the handset is lifted for transmission or reception, the hook switch (SW7) is turned on and the off-hook driver 26 is operated to apply an off-hook signal to the HK (Hook) terminal of the dialy 27. In general, when the handset is placed on the telephone, the on-hook state is called. At this time, the telephone is placed in the reception standby state. When the handset is lifted, it is called the off-hook state. At the time, the speech circuit 29 of the telephone is operated to enable a call. In this case, the signal is output from the DP (Dial Pulse) terminal of the dialy 27 to enable the line driver 28 to operate the speech circuit 29 to transmit or receive the signal.

On the other hand, when the MTR (Monitor) button of the keyboard 30 is pressed in order to dial while the handset is placed on the telephone, a signal is output from the HKCNTL (Hook Control) terminal of the dialy 27 and the line driver is output. Since 28 is enabled, the speech circuit 29 is operated so that transmission or reception is possible. Here, dialing in the on-hook state can dial the number of the other party by pressing the buttons of the keyboard 30 and the memory board 31, and there are two dialing methods, mechanical and electronic, with a selection switch (not shown). According to the position of mechanical), the signal is output from the DP terminal, and the electronic power is output from the DTMF signal from the T / O (Tone Out) terminal, and is input to each line driver 28 or speech circuit 29 and dialed. do. The liquid crystal panel 32 shows the current time, dial number, memory number, electronic / mechanical state, and the like.

Subsequently, in the voice synthesis unit D, when the voice is recorded, when the switches SW8 and SW9 are set to the R position and the operation button B _STT is pressed to apply the operation signal to the terminal S _TT , the microphone M1 is applied. The analog audio signal is input to the voice synthesis chip 33 through the voice synthesis chip 33, and the analog audio signal is converted into a digital signal and stored in the RAM 34. About 8 seconds. When the switches SW8 and SW9 are placed in the P position and the button B _STT is pressed to apply an operation signal to the terminal S _TT , the digital signal stored in the RAM 34 is analogized by the voice synthesis chip 33. The signal is converted into a signal and an audio signal is output from the terminal PLAY to the speech circuit 29. In the off-hook state, the voice signal is transmitted to the telephone line.

In the dial repeater unit E, when the system on signal is input to the terminal connected to the control box A, the off hook driver 26 is first disabled so that the intruder does not off-hook even if the intruder puts down the handset. Recorded sound) and a dial tone, and the sensor latch circuit 35 is enabled to operate when a detection signal is input, and at the same time, the counter 38 is enabled to operate.

Next, when the sensing signal is input, the sensor latch circuit 35 latches the signal and outputs the signal to the off hook driver 36. When the sensing signal is input, the off hook driver 36 first dialy 27. The phone is off-hook so that it can signal by dialing the terminal (HK). Then, the output of the off-hook driver 36 is delayed by about 600 ms in the 600 ms delay timer 37 to ensure countering. In other words, it is necessary to listen to the dial tone after dialing the handset during the call, and to make such a condition.

When a signal is input from the off-hook driver 36, the first signal C1 is output from the counter 38 to operate the memory driver 42 to dial the first emergency contact number. 42 is operated by the signal C1, but at the same time the 600 second delay timer 37 and the 1.5 second delay timer 41 are operated, during which time the memory driver 42 is disabled and then the dialy 27 is turned off. This is to prevent multiple outputs at the same time and to ensure dialing of the next number. On the other hand, if the signal C1 output from the counter 38 is input to the 40-second delay timer 39, the delayed for 40 seconds and then the off-hook driver 36 for 2 seconds by the 2 second time holder 40 is displayed. Is enabled. That is, the 2 second time holder 40 is on-hook for 2 seconds to redial, and then is off hook again.

In addition, the 5 second on / off timer 43 operates during 40 seconds when the signal C1 is delayed. At this time, the output from the timer 43 drives the play driver 44 to release the button B _STT . The recorded message is transmitted to the telephone line through the speech circuit 29 by applying the same signal to the voice synthesis chip 33. Since the recording time of the message is about 8 seconds, the same message can be sent four times. This is because the timer 43 drives the plaid driver 44 after 5 seconds, although 40 ÷ 8 = 5 times. In addition, when the off-hook driver 36 is disabled for two seconds and then enabled again, the 600-delay timer 37 is operated to apply a signal to the counter 38 so that the second signal C2 is output. Subsequently, the process is repeated as described above, and unless all other control signals are input, all the emergency contact numbers, for example, four telephone numbers, are dialed and the message is transmitted.

On the other hand, when the other station receives an emergency call of the sensor crime prevention telephone system according to the present invention when a ring signal is received and a call is received, the receiver hears a recorded message informing of an emergency, and the receiver stops the message by pressing the "#" button of the telephone. In addition, the situation where the sensor crime prevention telephone system is installed, that is, the site of the invasion, can hear and hear the sound heard from the microphone M2 of the room monitor unit F.

When the "#" button of the receiving station telephone is pressed, the "#" key decoder 45 receives this signal and outputs a message stop signal to the voice synthesis chip 33 to stop the transmission of the message. 46) is output to the speech circuit 29 through the room monitor microphone (M2) to be output to the telephone line. Here, the output of the "#" key decoder 45 enables the microdriver 46 and at the same time resets the 40 second delay timer 39 so that the situation of the field can be monitored for 40 seconds. Press the button again to extend the monitor time by 40 seconds, and if the button is not pressed after 40 seconds, the counter 38 resets, stopping dialing the remaining emergency contacts and returning to the initial state. Go back

It is not limited to the above embodiment of the present invention, it can also be used as a fire alarm by providing a sensor for detecting it in a predetermined position in a fire.
