When an object moves within the operating range, an output voltage or current is generated.
그리고 경보 회로에서는 상기 감지기에서 발생한 전압을 감지한 뒤 침입자가 있는 것으로 판단하고 경보를 발생시켜 침입자가 발생하였음을 알린다. 그런데 상기 감지기류는 외부 환경의 자극이나 간섭현상에 의해 자주 오동작을 발생하고, 사람이 아닌 가축이나 곤충의 움직임에 의해 작동할수 있으며 감기지의 감도가 높아 비교적 오동작이 잦은 단점이 있다.After detecting the voltage generated by the detector, the alarm circuit determines that there is an intruder and generates an alarm to inform that the intruder has occurred. By the way, the sensors are frequently malfunctioned by the stimulation or interference of the external environment, can be operated by the movement of livestock or insects, not humans, and has a relatively high malfunction due to the high sensitivity of the cold.
따라서 본 고안의 목적은 2개의 감지기를 사용하여 2개의 감지기 모두에서 감지신호가 발생할때만 감지신호를 발생함으로써 도난경보기의 효율을 증가시킬수 있는 회로를 제공함에 있다.Accordingly, an object of the present invention is to provide a circuit that can increase the efficiency of the burglar alarm by generating a detection signal only when a detection signal occurs in both detectors using two detectors.

The controller 105 includes a controller IC5, a resistor R5, and a capacitor C3. Finally, the alarm controller 110 includes a transistor Q1 composed of a diode D1 and a relay RY1. do.
따라서 상술한 구성에 의거 본 고안의 일실시예를 상세히 설명한다.Therefore, an embodiment of the present invention based on the above-described configuration will be described in detail.
먼저 제1감지기(101)가 작동하면 제1감도조절부(102)를 거쳐 제1지연부(103)내의 제1지연기(IC2)로 신호가 전달된다. 이때 제1지연부(103)는 원숏(one-shot)회로로 구성되고, 지연시간은 제1지연기(IC2)의 반전출력단(Q)의 출력 펄스폭(PW1)인 "저항(R1)·캐패시터(C1)"의 값에 의해 결정된다.First, when the first sensor 101 operates, the signal is transmitted to the first delay unit IC2 in the first delay unit 103 via the first sensitivity control unit 102. At this time, the first delay unit 103 is composed of a one-shot circuit, and the delay time is " resistance R1 ", which is the output pulse width PW1 of the inverting output terminal Q of the first delay unit IC2. Is determined by the value of the capacitor C1 ".
상기 제1지연기(IC2)의 비반전 출력단(Q)에는 제1발광소자(LED1)를 연결하여 상기 제1지연기(IC2)의 입력단(B)에 "하이"가 입력될 경우 이를 표시한다. 상기 제1지연기(IC2)의 반전출력단(Q)의 출력을 제어부(105)의 제어기(IC5)의 입력단(A)에 전달된다.The first light emitting device (LED1) is connected to the non-inverting output terminal (Q) of the first delay unit (IC2) to display when "high" is input to the input terminal (B) of the first delay unit (IC2). . The output of the inverted output terminal Q of the first delay unit IC2 is transmitted to the input terminal A of the controller IC5 of the controller 105.
제2감지기(106)가 작동하면 제2감도조절부(107)를 거쳐 제2지연부(108)에 제2지연기(IC4)의 입력단(B)에 전달된다. 상기 제2지연기(IC4)의 비반전출력단(Q)의 출력 펄스폭(PW2)은 "저항(R3)·캐패시터(C1)"의 값이 되며, 반전출력단()에는 제2발광소자(LED2)를 연결하여 감지상태를 표시한다.When the second sensor 106 is operated, the second sensor 106 is transmitted to the input terminal B of the second delay unit IC4 via the second sensitivity control unit 107. The output pulse width PW2 of the non-inverting output terminal Q of the second delay unit IC4 becomes the value of " resistance R3 / capacitor C1 " ) Displays a detection state by connecting a second light emitting device (LED2).
또한 비반전 출력단(Q)의 출력은 상기 제어기(IC5)의 입력단(B)에 전달된다. 상기 제어기(IC5)는 입력단(A)에 "로우"펄스와 입력단(B)에 "하이"펄스가 동시에 입력될때 비반전출력단(Q)에 "하이"펄스를 출력하므로서 트랜지스터(Q1)를 구동시킨다. 그리고 이때 릴레이(RLY1)가 구동하여 경보신호(GB)를 출력하게 된다.Also, the output of the non-inverting output terminal Q is transmitted to the input terminal B of the controller IC5. The controller IC5 drives the transistor Q1 by outputting a "high" pulse to the non-inverting output terminal Q when a "low" pulse is input to the input terminal A and a "high" pulse to the input terminal B at the same time. . At this time, the relay RLY1 is driven to output the alarm signal GB.
상기 제어기(IC5)의 반전출력단의 신호(Q)는 평상시 "하이"상태로 있다가 경보시에 "로우"로 되어 제1지연부(103)의 제1지연기(IC2)와 제2지연부(108)의 제2지연기(IC4)를 리세트하여 감지상태를 해제시키는 기능을 한다. 경보가 발생하는 시간인 제어기(IC5)의 비반전출력단(Q)의 출력시간(Palarm)은 "저항(R5)·캐패시터(C3)"의 값으로 결정 된다.The signal Q of the inverting output stage of the controller IC5 is normally in a "high" state and then becomes "low" in an alarm, so that the first delay unit IC2 and the second delay unit of the first delay unit 103 are in a state of being "low". The second delay unit IC4 of 108 is reset to release the detection state. The output time Palm of the non-inverting output terminal Q of the controller IC5, which is the time at which the alarm occurs, is determined by the value of " resistance R5 capacitor C3 ".
본 고안의 기능상은 특징은 제1감지기(101)의 지연시간인 "저항(R1)·캐패시터(C1)"가 제2감지기(106)의 지연시간인 "저항(R3)·캐패시터(C2)"에 겹쳐졌을때만 경보신호(GB)가 발생된다는 점이다.The functional feature of the present invention is that "resistance R1 capacitor C1", which is the delay time of the first sensor 101, is "resistance R3 capacitor C2", which is the delay time of the second sensor 106. The alarm signal GB is generated only when the signal is overlapped.
이외의 경우는 경보신호(GB)가 발생하지 않으며 감지된 신호는 무시된다. 상기 회로를 부가하여 2개 이상의 경우에도 적용할수 있다.In other cases, the alarm signal GB does not occur and the detected signal is ignored. The above circuit can be added and applied to two or more cases.
상술한 바와 같이 본 고안은 2개의 감지기(101,106)가 모두 동작할때만 경보신호(GB)를 발생시킴으로서 도난경보기의 효율을 증가시킬수 있는 이점이 있다.As described above, the present invention has an advantage of increasing the efficiency of the burglar alarm by generating the alarm signal GB only when both the detectors 101 and 106 operate.
