The present invention operating by the overall design system signal flow as described above will be described based on the specific circuit operation.

3 is a circuit diagram of the present invention. In order to use the telephone alarm device 44 installed as shown in FIG. 2, when a user plugs a power cord into an outlet, an AC voltage is generated from a rectifier RF through a power transformer PT. Since the rectified and rectified voltage is input to the regulator RG through the diode D ₁ , a stable B + voltage is supplied to each circuit part, while the voltage through the rectifier RF is applied to the resistor R ₁ (R ₂ ). Since the microcomputer 1 is supplied to the first port part of the microcomputer 1 through the microcomputer 1, the microcomputer 1 detects the power failure of the AC voltage. Auxiliary / battery (9) is prepared to keep checking the accident information from door open, temperature, and gas, and the voltage of this auxiliary battery (9) is regulated through the battery back-up diode (D ₂ ). B + before supplying stable The voltage is sent to each circuit part, where the diode D ₁ prevents the voltage of the auxiliary battery 9 from being induced into the resistor R ₁ (R ₂ ) for the electrostatic charge during a power failure.

In addition, the light emitting diode 34, which is a battery voltage check lamp, checks the voltage of the auxiliary battery 9 in the battery voltage check circuit 10 so that the voltage of the auxiliary battery 9 (here, 5V regulator RG) is driven. When the voltage and the voltage of the diode (D ₂ ) are added together, it is 7.6V) .When it is lower than 7.6V, it turns on to allow the external user to change and use a new battery. When the stand-by switch 35 on the plate is turned on, the B + voltage is applied to the first port portion 14 of the microcomputer 1 through the resistor R ₃ to be in a power-on state while the microcomputer 1 is turned on. In FIG. 4, the signal level (normally high state) of the door sensor 41 and the temperature sensor 40 connected to the fourth port unit 17 is detected.

At this time, if there is an abnormal state in the place where the sensing device is installed and one of the door sensor 41 or the temperature sensor 40 is operated, a low state signal is inputted to the fourth port portion 17 of the microcomputer 1 and the microcomputer The central processing unit 11 in (1) senses that the subscriber's telephone number (of three subscribers) data by the key operation of the keyboard 30 in FIG. 4) through the fourth port unit 17, the matrix keyboard 4 is sensed through the third port unit 16 under the control of the central processing unit 11, and the central processing unit 11 and The ROM 12 dials the first telephone number among the three subscriber numbers stored and stored in the RAM 13.

That is, the relay driving signal through the first port portion 14 of (1) of the microcomputer is applied to the transistor TR ₁ through the resistor R ₄ as the signal of (4-3) of FIG. according to the waveform of 4-3), a transistor (TR ₁₎ is the waveform below this state if the transistor (TR ₁₎ is applied to the base is turned on so that the relay (RY) and driving the contact (a) butge, wherein the relay (RY) Before contact (a) is attached (ON HOOK state), voltage of about DC48V is applied on telephone line (TL), and when (a) is attached (OFF HOOK state), it is transferred through coil of line transformer (LT). The transmission line T and the reception line R of the furnace TL are shorted to fall to about DC5V. Therefore, when the relay RY is operated in accordance with the waveform (4-3) of FIG. 4 supplied to the base of the transistor TR ₁ , the contact a of the relay RY is attached and moved away (4- '). As shown in Fig. 4), it appears on the telephone line TL so that the telephone dialing signal is sent to the first subscriber's telephone through the telephone station 47. At this time, when the telephone dialing is completed, the telephone dialing continues to the base of the transistor TR ₁ . Since the level is applied and the contact point a of the relay RY is attached and maintained on the telephone, the fixed message stored in the ROM 12 is transmitted to the subscriber through the telephone line TL, which is the telephone line of the subscriber. After the telephone is dialed to the TL, the microcomputer 1 starts to synthesize the voice signal through the first port unit 14 under the control of the central processing unit 11 to drive the voice synthesis integrated circuit 2. Low state to high state when supplied to the integrated circuit (2) In addition, since the voice data signal from the second port unit 15 is applied, the warning message signal which is the output signal of the voice synthesis integrated circuit 2 receives the filter 5 in the waveform as shown in Fig. 4-1 of FIG. It is changed into a waveform such as (4-2) and supplied to the OP amplifier 6 and the mute switch 36. First, a signal of a warning message such as (4-2) is supplied to the OP amplifier (C ₁ ). 6) is amplified and output to the telephone line (TL) via the line transformer (LT) to transmit the warning message content through the transceiver of the subscriber telephone.

In addition, a signal such as (4-2) through the filter (5) is supplied to the mute switch 36, where the contents of the warning message through the voice synthesis integrated circuit (2) do not want to be heard through the speaker (31). In this case, it is difficult to hear the contents of the message when the intruder invades. In such a case, when the mute switch 36 is turned on, the voice signal is cut off and the mute switch 36 is turned off when the user wants to send it out through the speaker 31. The audio signal is amplified by the power amplifier 7 through the condenser C ₂ and sent to the speaker 31.

After supplying the warning messages sent out in this way, the subscriber who is called through the condenser microphone 32 can monitor the indoor state where the telephone alarm device 44 is installed for about a dozen seconds. Since the condenser drive signal is changed from the low level to the high level from the one port part 14 and supplies power to the condenser microphone 32, the sound in the room state is transmitted to the OP amplifier 8 through the condenser microphone 32, From this, the output signal of the higher-sensitivity OP amplifier 8 is transmitted to the subscribers along the telephone line TL through the condenser C4 in the order of the OP amplifier 6 and the line transformer LT, and then the monitor. At the end, the microcomputer (1) needs to check whether the called subscriber has listened to the warning message correctly.

Then, the signal dialed to the telephone number subscriber is inputted through the telephone line (TL) to the ring signal waveform, which is the signal of Fig. 4 (4-5), to the telephone ring number and the telephone line check circuit (3). -6) is inputted to the third port portion l6 of the microcomputer 1 from the central processing unit 11, the ROM 12, and the RAM 13 of the microcomputer 1 from thereon. The number of waveforms generated in the high state is checked by the number of ringing. When the number of ringing rings and the number of ringing sounds stored in advance match the relay driving signal from the first port portion 14 of the microcomputer 1, the state is high. Since the above-described transistor TR ₁ is turned on, the contact a of the relay RY is attached to form a communication circuit.

Therefore, the voice message passing through the voice synthesis integrated circuit 2 described above passes through the filter 5, the OP amplifier 6, the line transformer LT, and the telephone line TL, and is sent to the telephone number subscriber.

On the other hand, the telephone ring number and the telephone line check circuit 3 serves to shape the waveform of the ring tone coming into the telephone line TL by the microcomputer 1 as shown in FIG. 4 (4-6). The phone line TL is disconnected or shorted to have a waveform such as (4-7) so that the microcomputer 1 detects the microcomputer 1, and when the microcomputer 1 detects the emergency, the first port unit 14 makes an emergency. By operating the bell 45 will notify the person in the room.

In the above state, the door open and abnormality shown in FIG. In addition, the door sensor 41 and the temperature sensor 40 is in the standby state of detecting the signal. Alternatively, if the user presses the emergency button 43 used in an emergency, the emergency signal is high and the first state of the microcomputer 1 is removed. Since it is applied to the four-port unit 17 and operated by the flute chart shown in FIG. 6, the description of the operation is omitted since it is the same as the operation state when the door open and abnormal temperature are detected.

Therefore, when the telephone alarm device detects an abnormal state in the microcomputer 1, the above-described operation is performed, and a signal is transmitted from the first shift unit 14 of the microcomputer 1 so that the alarm light emitting diode 33 is swung. At the same time, the external emergency bell 45 is operated so that the emergency and the disaster is notified to the inside and outside.

As described above, the present invention checks the input of accident information from all the sensing devices (door open, temperature, emergency button) at the microcomputer and notifies the internal and external status through the emergency bell and the speaker, and at the same time dials under the control of the microcomputer. By sending a warning message to subscribers of telephone numbers, it is effective to prevent or prevent the emergency and disaster of the place where the telephone alarm system is installed by calling for help.
