The present invention relates to an emergency contact alarm system for a villa or a condominium or a multi-family house having a small number of households. It's about emergency call alerts that let you know immediately so that you can deal with unpleasant accidents.

In general, a gas leak alarm system that detects and alerts when a gas leak is detected, and a number of functions such as a visitor's identification device and a method for preventing theft are modularized into one main device so that it can be controlled uniformly by the main device. Best known for automation systems.

The advantage of this system is that it automatically operates by modularizing each necessary function (gas leak, method, visitor check device, etc.) for the purpose of protecting the facility and preventing human injury. Has the advantage of being comfortable.

However, such a home automation system can be used only for one's own home, even if it is an apartment with a large number of households, a villa or a coalition with a small number of households, or a single house where only one family lives. It's just a system.

That is, for example, when a gas overflow leaks, a signal from the gas leak detection sensor is sent to the home automation system, and an alarm is normally generated. However, the alarm is not intended to be delivered to other homes, but the home to which the system belongs. It has a meaning to convey only to person.

As a result, in the absence of a person, it may be impossible to cope with it, and it may have a fatal effect on other homes. In addition, when an intruder such as a robber breaks in, there is no device to contact outside. There were many problems, including being in trouble.

Accordingly, in view of the above problems, the present invention displays alarm means or a lamp in the case of an intruder such as a robbery, a gas leak accident or a fire accident in the absent home, or a home other than the absent home. Its purpose is to provide an affordable emergency contact alert system that can be contacted by means to respond promptly and proactively to anticipated unfavorable incidents.

In order to achieve the above object, the emergency contact alarm system according to the present invention is provided with an analog switch which connects a heat sensor, a gas sensor and an emergency switch in parallel and sets data corresponding to each household. A latch unit for latching a signal applied when the sensor or switch is activated, a decoder for decoding the signal output from the latch unit, a light emitting diode operated according to the signal output from the decoder, It is characterized by a built-in trigger unit for controlling the alarm driving circuit for driving the buzzer by the output of the OR gate to OR the signal output from the decoder.

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

1 is a front view of a terminal installed in each home while being a basic model in the emergency contact alarm system of the present invention.

In the drawing, (N1 to N5) is a name tag for setting household head names of each household to help understand the present invention, and (LED1 to LED5) is a light emitting diode group shown in FIG. (18) is a heat sensor (one of F1 or F2 to Fn) belonging to one household and a gas sensor (G1 or G2 to Gn) of the same household. ) Is a pack holder for fixing), (19) is a grill portion through which a plurality of holes pass so that the alarm sound of the buzzer (14) can leak out well, (20) is a set signal stored in the latch portion (10). Reset switch to clear.

One terminal configured as described above may install five terminals A to An corresponding to each household, assuming that five households live in a building, and each terminal A to An is illustrated in FIG. As described above, the thermal sensors F1 to Fn, the gas sensors G1 to Gn, and the emergency switches S1 to Sn are included. These power supply systems have a common DC power source (DC) rectified from the power supply unit 17 having a battery 16 for charging and discharging to which an AC power source (AC) is applied, as shown in FIG. Lines are formed in parallel to be supplied to each circuit of An).

If more than five households are housed, more expansions may be possible. That is, as shown in FIG. 3, the thermal sensor Fn, the gas sensor Gn, and the emergency switch Sn and In addition, the analog switch (an) and the terminal circuit (A) as shown in FIG. 4 can be further expanded, and the output terminal of the light emitting diode and the decoder (11) and the input terminal of the or gate (12) can be further expanded. You can set as many as add.

In such a state, when an intruder such as a robbery intrudes into the N1 home where each terminal is installed, if any one of the N1 homes presses the emergency switch S1 installed in an arbitrary place, the signal is transmitted through the analog switch a1. It is applied to the latch portion 10 of the terminals (B ~ An) installed in.

At this time, the latch unit 10 temporarily stores the set signal and keeps it until it is cleared by the reset switch 20.

The signal set in the latch unit 10 is input to the decoder 11, and the decoder 11 encodes the signal set in the latch unit 10. In A), the output is not sent by the promised coded signal of the decoder 11 belonging to it. At this time, the LED groups LED1 to LED5 and the buzzer 14 belonging to the terminal A of the N1 home are not operated.

However, the analog switch a1 in the N1 home and N2 to N5 are configured in parallel circuits so that the output stages of the analog switches a1 to a2 in the home are set at the same time. It passes to each decoder 11 via each latch part 10 which belongs to the terminal B-An of other homes N2-N5 except this invading N1 home.

Each decoder 11 belonging to the terminals B to An of the N2 to N5 households outputs a "high" signal to an output terminal to which the light emitting diodes LED2 to LED5 are connected according to a predetermined rule. Therefore, since the "high" signal is supplied through the resistors R2 to R5 to the light emitting diodes LED2 to LED5 protruding outside the terminals B to An of the N2 to N5 homes except for the N1 home, the light emitting diodes LED2 to LED5. ) Lights up.

On the other hand, the "high" signal output from the decoder 11 of the terminal (B ~ An) of the NW ~ N5 hypothesis is applied to the input terminal of the trigger unit 13 by being ORed at the OR gate 12, The trigger unit 13 oscillates with a pulse for driving the buzzer 14, which will be described later, by the CR time constant circuits C1 and C6 for smoothly determining the characteristic of the oscillation frequency and outputting it to the output terminal θ. do. The transistor TR1 is switched according to the oscillation pulse so that the oscillation pulse output from the output terminal θ of the trigger unit 13 is supplied to the base terminal of the transistor TR1 of the alarm driving circuit 15. ).

Accordingly, the terminals a2 to a5 of the N2 to N5 homes, except for the N1 home, generate an alarm by each buzzer 14 belonging thereto, and the light emitting diode LED1 of the N1 home is not turned on so that the N2 to N2 homes are not lit. N5 homes will recognize that an intruder has invaded N1 homes.

)에 "로우"와 "하이"신호를 각각 출력함으로써 래치부(10)는 클리어됨과 동시에 경보구동회로(15)의 작동을 정지시켜 부저(14)가 구동되지 않도록 한다.In this way, when the reset switch 20 shown in FIG. 4 is turned "on" in the N2 to N5 homes that recognizes that an intruder has entered the N1 home, the signal of each output terminal of the decoder 11 becomes "low". The light-emitting diodes LED2 to LED5 are turned off, and the output signal of the OR gate 12 is inverted from "high" to "low", so that the trigger unit 13 is operated to output the terminals θ, (

By outputting a "low" and a "high" signal to the), the latch unit 10 is cleared and the operation of the alarm drive circuit 15 is stopped to prevent the buzzer 14 from being driven.

This circuit operation is not only N1 home, but also any of N2 ~ N5 homes by pressing the emergency switch to inform the emergency, alarm and display by the buzzer and light emitting diodes of other homes except the pressed home.

In addition, the heat detection sensor (F1 ~ Fn) and the gas detection so that each terminal (A ~ An) installed in each emergency contact alarm device of the emergency contact alarm system of the present invention to notify that the fire has occurred by the heat detection in the event of fire By installing the sensors (G1 ~ Gn), as in the emergency switch (S1 ~ Sn) operation by the intruder will be informed that there is an accident by the alarm and light emitting diode display.

On the other hand, in consideration of the case where a person is absent in the home where the terminals A to An are installed, the CR time constant circuits C1 and R6 are connected to the trigger unit 13 shown in FIG. ) And the lighting signal of the light emitting diodes LED1 to LED5 included in each terminal A to An and the alarm sound signal of the buzzer 14 are generated only for a predetermined time by the time constant value of the resistor R6. It can be replaced by a variable terminal that adjusts the time constant value as needed.

In addition, when the wires of the emergency switches S1 to Sn connected to the terminals A to An of each of the homes N1 to N5 are disconnected, the control signal of the analog switches a1 to an is set low. It goes high, which is the same as when the emergency switch is turned on, and outputs an alarm or light indication to each home that the cable is abnormal in a broken home.

Each terminal of the emergency contact alarm system according to the present invention as described above is connected to an alliance, a villa or a multi-family house, and connected to each other in case of an intruder from each home or in case of a fire or gas leak. Alarms and lamps are displayed so that they can cope with methods and disaster prevention accidents.
