Description
제1도는 본 고안의 회로도.1 is a circuit diagram of the present invention.
* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings
1 : 안테나 2 : 증폭회로1 antenna 2 amplification circuit
3 : 레귤레이터 4 : 발진회로3: regulator 4: oscillation circuit
Q : 트랜지스터 R : 저항Q: Transistor R: Resistor

본 고안은 특징 포탄의 근접신관에 있어서 목표물의 감지 거리를 다 확산시켜 정밀도를 높이도록한 포탄근접신관의 거리 감지 회로에 관한 것이다.The present invention relates to a distance sensing circuit of the shell proximity fuse to increase the accuracy by spreading the sensing distance of the target in the proximity fuse of the feature shell.
특정 구경을 갖는 포탄의 근접 신관 내부에는 발진회로가 내장되어 있어 발사직후 안테나를 통하여 주파수를 출력 시킴에 따라 최초 출력 주파수와 반사파의 차이 즉 도플러 신호로서 목표물의 근접지점을 파악하여 목표물에 적정한 범위내에 도달하면 점화신호를 뇌관에 보내어 포탄을 폭발시키도록 되어 있다.The oscillating circuit is built in the shell of the shell with the specific aperture, and as the frequency is output through the antenna immediately after launch, the difference between the initial output frequency and the reflected wave, that is, the Doppler signal, is determined to determine the proximity of the target to the target. When it reaches it, it sends an ignition signal to the detonator to explode the shell.
따라서 일반적으로 제작되는 포탄 근접 신관에 있어서는 발진회로에서 출력되는 주파수를 직접 안테나를 통하여 방사시킴으로서 안정되지 못하고 비교적 약한 주파수로 인해 목표물의 감지거리가 축소되어 정확한 근접기능을 갖기에는 많은 문제점이 야기되었던 것이다. 그러므로 본 고안은 상기와 같은 문제점을 해결하고자 안출된 것으로서 발진회로에서 출력되는 주파수를 레귤레이터를 통해 안정화 시킨뒤 다시 증폭시켜 트랜지스터 근접 신관의 거리 감지 회로를 제공하는데 본 고안의 목적이 있는 것이다.Therefore, in general, the manufactured shell proximity fuses emit a frequency output from the oscillator circuit directly through the antenna, which causes unstable and relatively weak frequency, reducing the sensing distance of the target, causing many problems to have accurate proximity function. . Therefore, an object of the present invention is to provide a distance sensing circuit of a near-fuse transistor by stabilizing the frequency output from the oscillation circuit through a regulator and amplifying it again.
이하 첨부된 도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings as follows.
제1도에서와 같이 통상의 근접신관에 내장된 발진회로(4) 출력신호를 레귤레이터(3)를 통하여 증폭회로(2)에 인가하되 증폭회로(2)의 출력단은 콘덴서(C)와 트랜지스터(Q) 베이스단으로 각각 연결함과 동시에 상기 트랜지스터(Q) 에미터측은 저항(R)을 거쳐 콘덴서(C)와 접속하여 그라운드 되게 하고 또한 콜렉터단은 안테나(1)에 연결되도록한 것이다.As shown in FIG. 1, the output signal of the oscillator circuit 4 embedded in the normal proximity fuse is applied to the amplifier circuit 2 through the regulator 3, and the output terminals of the amplifier circuit 2 are the capacitor C and the transistor ( Q) At the same time, the emitter side of the transistor (Q) is connected to the capacitor (C) through the resistor (R) and grounded at the same time, and the collector end is connected to the antenna (1).
상기와 같은 구성으로 이루어진 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention made of the configuration as described above are as follows.
먼저, 포탄을 발사할때 배터리에서 발진회로(4)에 전원을 인가하여 발진을 시작하게 되며 이때 출력되는 주파수는 레귤레이터(3)로 전달되어 안정화된 신호로 만든후 증폭회로(2)에 인가하여 일정한 크기를 갖는 신호로 증폭된 신호가 트랜지스터(Q)베이스에 인가됨에 따라 상기 트랜지스터(Q)가 턴온상태가 되어 콜렉터에 접속된 안테나(1)를 통해 방산되는데 이때 트랜지스터(Q) 에미터 단에 매개된 저항(R)값이 높게 되면 콜렉터 전위가 증가하여 안테나(1)의 출력이 크게 됨으로서 목표물의 감지거리가 확대되는 것이다.First, when the shell is fired, the battery starts to oscillate by applying power to the oscillator circuit 4, and at this time, the output frequency is transmitted to the regulator 3 to make a stabilized signal and then applied to the amplification circuit 2. As a signal amplified by a signal having a predetermined magnitude is applied to the base of the transistor Q, the transistor Q is turned on and is dissipated through the antenna 1 connected to the collector. When the mediated resistance (R) is high, the collector potential is increased and the output of the antenna 1 is increased, thereby increasing the sensing distance of the target.
여기에서 콘덴서(C)는 바이패스용으로 사용하였다.Here, the capacitor C was used for bypass.
이상에서 상술한 바와같이 근접신관 내부에 발진회로(4)에서 출력되는 발진주파수르 레귤레이터(3)와 증폭회로(2) 경유케하여 안정화를 꾀하 다음 트랜지스터(Q) 에미터단의 저항(R)값을 높게 설정하여 안테나(1)을 통한 주파수의 출력이 크게 되어 감지거리가 확대 됨으로서 보다 정밀한 근접기능을 획득할 수 있는 유용한 고안인 것이다.As described above, stabilization is performed through the oscillation frequency regulator 3 and the amplification circuit 2 output from the oscillation circuit 4 inside the proximity fuse, and then the resistance (R) value of the emitter stage of the transistor (Q). It is a useful design to obtain a more precise proximity function by setting the high to increase the output of the frequency through the antenna (1) to increase the detection distance.
