The present invention relates to an automatic alarm device using a telephone line, in particular, the phone number and caller's location and the voice information of the emergency location in a specific place (for example police box, guard room, etc.) are stored and stored when contacting a sensor by an intruder. The present invention relates to an automatic alarm device which is connected to a place of a telephone number first and informs a receiving party of voice message information such as a location and an emergency state of a receiving party so as to be useful for criminal arrest or combating. In the conventional alarm device for the purpose of this type of method, the receiving party's telephone number is randomly memorized in the calling party's telephone. Although the telephone number of is selected, the alarm signal can be sent. However, this is because the telephone number of the calling party remembers the receiving party's telephone number frequently used in the calling party's phone and selects one number if necessary. Although it is advantageous to provide the convenience of the receiver's telephone user by being connected to the receiver, even if the receiver's telephone is selected as one number in case of an emergency, an alert is sent to the other party to indicate the current situation of the calling party.

It is. In addition, in the voice circuit 16 of the voice synthesizer 16, which is stored in the memory 17 by the voice input means, and the loop number or voice synthesizer 16 of the telephone number stored in the external subscriber's or arbitrary destination's telephone number setting. Since the basic circuit configuration of the tone generating unit 19 for pulsing the output voice is only a general circuit configuration as shown in FIG. 3, detailed descriptions thereof will be omitted. The operation of the embodiment of the present invention configured as described above will be described with reference to FIGS. 3 and 4.

First, a method for storing an external subscriber (a subscriber of a place to be contacted in case of emergency) or a telephone number of a battery when going out is to turn on the slide switch (S, SW) set in the key setting unit 20. _A loop is formed between ₁ and L ₂ and the tone generator 19 to receive a voltage for dial tone of the telephone station EXC. At this time, the tone generating unit 19 is driven by the voltage for the dial tone of the telephone station EXC and at the same time, by selecting the corresponding telephone number key using the key setting unit 20 connected thereto, illustration of the tone generating unit 19 is omitted. The desired phone number in its own memory. Once its phone number is set, the slide switch (S.SW) is restored to its original off position. At this time, if you want to change the phone number crawled in the memory of the tone generating unit 19, if the re-operation in the same manner as described above the old memory phone number data is removed and the new phone number is stored. In addition, the microphone 17 and the recording circuit of the voice input unit 18 transmit the caller's location and other voices of the emergency contents to be transmitted to the external subscriber in case of an emergency in the memory 17 through the voice synthesis unit 16. The signal is converted into memory data suitable for storage by the speech synthesis section 16 and stored in the memory 17 at the caller side location and emergency information. As described above, the transistor of the first delay unit 10 is normally stored in the waiting state after storing the necessary telephone number, the caller's position, and the emergency contents in each memory. Since the transistor Q ₁ is turned off because the base end of Q ₁ is 'low', the first relay Ry ₁ of the relay and the relay contact part 12 does not operate. Accordingly, the light emitting device LED ₁ connected to the b contact Ry ₁ b of the first relay Ry ₁ is turned on as shown in FIG. 4a to indicate that there is no intruder at the same time, and the alarm device 2 operates normally. You can see that.

At this time, if the on (high) signal of the instantaneous contact as shown in FIG. 4b is detected from each of the sensors S ₄ and S ₅ and the reed switches S _1- S ₃ of the sensing unit 1 installed at each anticipated intrusion position, the first delay is detected. The base terminal of the transistor Q1 of the unit 10 becomes the 'high' level for a while to turn on the transistor Q1 and simultaneously excite the relay Ry ₁ -Ry ₃ , but each sensor S of the sensing unit _{1 is} excited. ₄ , S ₅ ) or the moment the contact of the switch (S ₁ -S ₃ ) is off again, the transistor Q ₁ is returned to the off state. Since the same time, applied to the base of the first delay unit (10) resistance (R ₁₎ as the 4c help by the capacitor (C ₁₎ is charged potential is discharged discharge potential, the transistor (Q ₁₎ of the transistor (Q ₁₎ Keep on operation for a certain time. The re-operation timing of the transistor Q ₁ by the first delay unit 10 is a time point at which each contact point of the sensing unit 1 is opened as shown in FIG. 4B (a time point at which the high level is changed from the 'high' level to the 'low' level). ), And the delay operation period is delayed by the set time constant of the resistor R ₁ and the capacitor C ₁ . As a result of the delay time constant of the first delay unit 10, the first relay Ry ₁ of the relay and the relay contact unit 12 is kept in operation to switch its a and b contacts, and at the same time the emergency of the display unit 13 The status display light emitting element LED ₂ is turned on to indicate that an emergency state by an intruder has occurred. At the same time, its other a contact Ry ₁ a is shorted to excite the second and third relays Ry ₂ and Ry ₃ . Accordingly, the second relay (Ry ₂₎ is a hook switch (HS) an on telephone company at the same time flow through the trunk line (L ₁₎ of the short circuit contact a (Ry ₂ a) trunk line (L ₁₎ (EXC) voltage which by It is applied to the tone generator 19 via the bridge circuit 14 (BD) to operate it.

At the same time, the second stage a contact Ry ₃ a of 2 is commonly shorted by the third relay Ry ₃ to apply a redial signal (+ RD / -RD) to the tone generating unit 19, The synthesizer 16 provides the voice drive signals P ₁ and P ₂ . At this time, the delay on pulse ('high': 4c) of the first delay unit 10 is output, and after the charge delay time t ₁ for a predetermined period of time, the resistance of the first delay unit 10 R ₁ , The charging potential of the capacitor C _{2 in} the second delay portion 11 is discharged by the resistor R ₄ by the oscillation pulse generated by R ₂ ) and the capacitor C ₁ . The driving of the third relays Ry ₂ and Ry ₃ is extended for t ₂ hours to delay the operation. The reason for extending the delay time by t ₂ by the second demonstration unit 11 is to capture the dial tone through the trunk lines L ₁ and L ₂ , and to perform the redial period for the busy tone and the tone generator 19. This is to sufficiently transmit the tone signal of the external subscriber telephone number stored therein and the voice information (caller side position and emergency contents) stored in the memory 17 through the voice synthesis unit 16 to the external subscriber. Therefore, when the charge delay oscillation pulse of t ₁ is converted to 'low' by the first delay unit 10, the second relay Ry ₂ and the third relay Ry _{3 are} formed as shown in FIGS. 4k and l. At the same time, the tone generating unit 19 and the voice synthesizing unit 16 are driven as shown in FIGS. 4G and h, and the data stored in each memory is transferred through the final tone generating unit 19 to the trunk lines L ₁ and L _2. ) Accordingly, through the CO lines L ₁ and L ₂ , the tone generating unit 19 loops and tone pulses the external subscriber's telephone number and its location and voice information stored on the caller's side, respectively. It is delivered to the subscriber (arbitrary battery).

At the same time, an alarm is generated through the alarm generating unit 15 connected to the a contact (Ry ₃ a) terminal of the third relay (Ry ₃ ) of the relay and the relay contact part 12, which alarms the intruder. Choose from as needed. Thereafter, when the potential charged in the capacitor C ₁ of the first delay unit 10 is discharged and the set delay time t ₃ is completed, the base potential of the transistor Q ₁ falls to the 'low' level. At the same time as the transistor Q ₁ is turned off, the first relay Ry ₁ is turned off to be in an initial standby state, and a delay operation is performed for a period of t ₂ when the operation of the first delay unit 10 is completed. When the potential charged in the capacitor C ₂ of the unit 11 is discharged and the set delay time t ₄ is completed, the base potential of the transistors Q ₂ and Q ₃ falls to the 'low' level. The two Darlington connection transistors Q ₂ and Q ₃ having symmetry are turned off, and at the same time, the second and third relays Ry ₂ and Ry ₃ are turned off to return to the initial standby state to display the normal state of the display unit 13. The light emitting device LED ₂ is turned on, and then each sensor S ₄ (S ₅ ) and the switch S of the sensing unit 1 at that time _{When the} detection signal is applied in ₁ -S ₃ ), the above operation is repeated.

As described above, according to the automatic alarm device of the present invention, a plurality of intrusion detection sensors, such as a reed switch or an infrared sensor, are installed for each element that is expected to be intruded, so that an outsider's intrusion through contact operation can be arbitrarily selected through a telephone main line. The location of the caller's side and the corresponding emergency information can be sent to the subscriber's phone at the place, indicating that an emergency has occurred. As it can be notified, there is a feature that can effectively perform the security function.
