The present invention relates to an alarm device in an emergency, and in particular, processes signals detected from various sensors (heat, gas, water leakage, intrusion, fire, theft, crime prevention sensor, etc.) to call a reserved place for emergency conditions. It is about an alarm that can be notified immediately.

Conventional alarm devices in this regard include a variety of sensors for detecting a change of state, and a buzzer or alarm (including a lamp) for notifying a situation after detecting an abnormality from these sensors and detecting a buzzer or alarm when a signal is detected from these sensors. Either ring or drive the lamp to alert you of an emergency.

However, such alarms are not only limited to devices in their own area (in buildings or homes), but also lack the ability to communicate emergency situations to those in the immediate vicinity. In addition, there is a problem that a major damage is expected because the site is not immediately known if an emergency situation occurs in the absence.

The present invention, in view of the above-mentioned problems in the absence or during bedtime, can likewise remember the phone number of the place where you want to be located, or can reserve a phone number, such as a public office or a place with a good contact By constructing a circuit, when an emergency situation occurs due to signals detected from various sensors, it is possible to immediately notify an emergency situation to the corresponding government office or a reserved place where oneself is located so that the expected damage is minimized. It is an object of the present invention to provide an alarm device in case of emergency so that the present invention can be reduced as follows.

As shown in FIG. 1, the alarm device of the present invention includes a keyboard 8 for reserving a telephone number for giving a dial tone for a public office corresponding to each sensor or a place where one is located, and an input from the keyboard 8. A display circuit 7 for displaying the data, a latch circuit 6 for temporarily latching data exchanged between the keyboard 8 and the display circuit 7, and a memory circuit 10 by the microprocessor 1; Address decoder 9 which decodes the specified address of < RTI ID = 0.0 >), < / RTI > a bus drive circuit 5 which drives the address and data and control bus of the microprocessor 1, and a new telephone by erasing previously reserved telephone number data. A reset circuit (3) for resetting the number data and a sensor interface for interrupting the microprocessor (1) by receiving signals detected from various sensors Input from the keyboard 2 and the clock generation circuit 4 for generating a predetermined clock as a time reference signal of an operation processed by the microprocessor 1 and the tone detection circuit 12; The memory circuit 10 is composed of a RAM for storing the telephone number data and a program ROM, and the microprocessor 1 and the telephone 16 are shared by receiving data about a telephone number stored in the RAM of the memory circuit 10. A dialing circuit 11 for dialing a telephone to a place reserved for communication connection and a telephone line state at a primary reserved place dialed by the dialing circuit 11 to detect or receive a ring signal even when a ring signal is output. When there is a signal detected by the tone detection circuit 12 and the various sensors to inform the microprocessor 1 of the counterpart phone so that the next second reserved place can be called during a call. The automatic switching arc 14 and the dialing circuit 11 which receive the high signal decoded by the response decoder 9 through the or gate 15 and convert it into a telephone capable of informing the emergency situation of the ordinary telephone. And a telephone line interface circuit 13 for receiving the dialed data and interfacing to a general telephone trunk line.

Referring to Figure 1 the effect of the present invention configured as described above is as follows.

That is, as shown in FIG. 1, when the power required for each circuit is supplied to a power supply unit (not including a backup circuit) not shown, the tone detection circuit 12 and the predetermined clock generated by the clock generation circuit 4 are supplied. The microprocessor 1 operates to regularly execute the program of the ROM in the memory circuit 10.

At this time, the microprocessor 1 initializes the memory RAM to receive a desired telephone number through the keyboard 8, that is, a telephone number of a number of places that conveyed an emergency situation when an emergency occurs. The telephone number data of the relevant place corresponding to the scanned various sensors is sequentially stored in the RAM in the memory circuit 10 through the latch circuit 6.

In this state, when a signal detected from various sensors is applied to the interrupt terminal INT of the microprocessor 1 through the sensor interface circuit 2 due to a certain situation, the microprocessor 1 receives the signal of the input sensor. The code data corresponding to the signal input through the bus driver circuit 5 and the address decoder 9 is outputted to the input terminal of the or gate 15.

When any one of these input signals is a 'high' signal is output, the 'high' signal is output, so the automatic switching circuit 14 forms a communication path so that the phone can be used in a state in which the telephone can be used normally. Switch to the phone at the reserved location.

Here, if the signal detected from each sensor is a signal detected from an intrusion sensor, for example, the microprocessor 1 is located in the memory circuit 10 (e. The telephone number data of the place) is read and output to the dialing circuit 11.

Therefore, since the dialing circuit 11 is in a state in which a call path in a state in which the data read by the microprocessor 1 can receive and make a call by the automatic switching circuit 14 is formed, The corresponding data is inputted through a telephone line interface circuit 13 to a row and a column of a telephone circuit (not shown) embedded in the telephone 16 itself so that a signal such as pressing a key button of the telephone is reserved. Dial.

At this time, the tone detection circuit 12 detects the state of the telephone line at the reserved place by the tone detection function of advancing the ringing tone from 305 to 640HZ, and if the ringing tone is sent for a predetermined time, the tone detecting circuit 12 does not receive it at the first reserved place or When the call is in progress, the microprocessor 1 is notified and the microprocessor 1 dials the telephone number of the second designated place stored in the RAM of the memory circuit 10.

When receiving a telephone at a place reserved for the first or second dialed call, the phone is in an emergency situation by periodically generating tones or voices that generate a program of a ROM in the memory circuit 10 over a period of time. Will be delivered immediately.

The tones or voices can be set differently so as to easily identify signals detected from various sensors, which can be easily judged on each floor or at a certain place in a high-rise building, etc., and can also avoid user confusion. Make sure

As described above, according to the present invention, it is possible to be protected from illegal intruders such as robbery by making a call to a reserved place automatically by signals detected from various sensors, and also to prevent fire and theft during absence or sleep. Even if this happens, it is possible to immediately respond to this, it is possible to prevent damage to property and life.
