철도신호기의 오작동 방지장치{The error operation preventive system of railroad signal flag}The error operation preventive system of railroad signal flag}

본 발명은 철로용 신호기의 오작동 방지장치에 관한 것이며, 조작반과 신호기 사이에서 발생되는 각종 유도전력에 따른 신호기의 오작동을 해소하기 위한 것이다.The present invention relates to a device for preventing malfunction of a railway signal, and to solve a malfunction of a signal according to various induced powers generated between an operation panel and a signal.

철도와 지하철에는 철로 위에 여러개의 객차가 직렬로 연결되어 신호기의 지시에 따라 철로변경, 진행, 정지,서행을 수행하게 된다.In the railway and subway, several passenger cars are connected in series on the railroad, and the railroad is changed, proceeded, stopped, and slowed down according to the signal signal.

이와 같은 철로에 설치되는 신호기는 조작반에서 신호기까지의 거리는 짧은경우 수미터이고, 긴경우에는 수킬로미터에 이르게 되고, 신호기에 사용되는 공급전압은 50V, 110V, 220V에서 선택사용되고, 전용신호기 제어모듈을 사용하게 되므로 50V, 110V, 220V에서 선택된 전원이 입력되면 정류부와 LED드라이브를 거쳐 LED신호기가 동작하게 된다.The signal installed in the railway is several meters from the operation panel to the signal when it is short, and it reaches several kilometers when it is long. Since the selected power is input from 50V, 110V, 220V, the LED signal is operated through the rectifier and the LED drive.

또 LED신호기의 경우 LED드라이브와 제어모듈은 신호기 내부에 내장된다.In the case of LED signal, LED drive and control module are embedded inside the signal.

이와 같은 종래의 신호기는 조작반에서 신호기 사이를 통과하는 각종 유도전력(유도전압, 유도전류, 유도전력)에 노출됨으로써 조작반에서 지시되지 않은 상태(전원이 공급되지 않은 상태)에서도 신호기에 유도전력이 흐르게 되어 신호기가 오동작하게 된다.Such a conventional signal is exposed to various induction powers (induction voltage, induction current, induction power) passing between the signals in the operation panel so that the induced power flows in the signal even when the operation panel is not instructed (power is not supplied). The signal will malfunction.

이와 같이 유도전력에 의해 신호기가 오동작함으로써 철로를 주행하는 객차의 운전자인 기관사는 오작동된 신호기를 현시(現視)하고 주행함으로써 사고로 이어지는 문제점이 발생되고 있다.In this way, a driver who is a driver of a passenger car traveling on a railroad track due to a malfunction of a signal by induced power exhibits a problem that leads to an accident by displaying and driving a malfunctioning signal.

이에 본 발명은 종래의 위와 같은 제반결점을 해소하고, 철로의 조작반에서 신호기 사이를 통과하는 각종 유도전력은 컨버터와 LED드라이브의 유도전류차단회로에서 차단하고 조작반의 공급에 따른 전력으로만 신호기를 작동할 수 있는 오작동 방지장치를 제공함에 목적이 있다.Accordingly, the present invention solves the above-mentioned drawbacks of the prior art, the various induced power passing between the signal in the operating panel of the railway is cut off in the induction current blocking circuit of the converter and the LED drive and operate the signal only by the power according to the supply of the operation panel It is an object of the present invention to provide a malfunction prevention device.

본 발명은 도1과 같이 조작반의 신호기 제어모듈로 전원이 입력되면 자동전압인식회로를 거쳐 정류부에서 정류하고, 이를 컨버터에서 사용전압으로 변환하고 LED드라이브와 유도전류차단회로를 병렬로 구성하여 LED신호기에서 동작할 수 있도록 구성된다.The present invention is rectified by the rectifier through an automatic voltage recognition circuit when the power is input to the signal control module of the control panel as shown in Figure 1, converts it to the voltage used in the converter and LED drive and induction current blocking circuit in parallel to configure the LED signal It is configured to work on.

이와 같은 본 발명의 작용효과를 설명하면 다음과 같다.Referring to the effects of the present invention as follows.

도1과 같이 조작반의 신호기 제어모듈로 전원이 입력되면(AC 85-265V, DC 120-374V) 자동전압인식회로에서 인식하고 정류기에서 정류된 다음 설정된 DC전류로 변환하여 컨버터(트랜스 포함)로 입력되고, 컨버터로 입력된 전류는 안정화되어 신호기의 LED드라이브에 입력되고 LED신호기에서 동작이 이루어지게 된다.When power is input to the signal control module of the control panel as shown in Fig. 1 (AC 85-265V, DC 120-374V), it is recognized by the automatic voltage recognition circuit, rectified by the rectifier, and then converted to the set DC current to be input to the converter (including transformer). Then, the current input to the converter is stabilized is input to the LED drive of the beacon and the operation is performed in the LED beacon.

이와 같이 본 발명은 조작반에서 신호기를 작동시킬때 자동전압인식용 회로에 전원이 연결되면, 동 전원은 정류기를 통과하여 정류되어 컨버터로 입력되어 사용전압으로 변환되고, LED드라이브를 거쳐서 LED신호기가 동작되고, 조작반에서 신호기의 전원을 차단하여 꺼진 상태에서 조작반과 LED신호기 사이에 유도전력(유도전압, 유도전류)이 흐르게 되면 설정전압보다 낮은 유도전력은 컨버터에서 차단되고, 설정전류보다 낮은 유도전류는 LED드라이브의 유도전류차단회로를 거치면서 차단되므로 조작반과 신호기 사이의 거리에 구애 없이 유도전력(유도전압, 유도전류)를 효과적으로 차단하게 됨으로써 유도전력에 의한 신호기의 오작동이 해소되고, 또 AC 85-265V와 DC 120-374V의 범위의 전압을 자동으로 인식할 수 있는 자동전압인식회로를 부가하여 사용하게 됨으로써 사용전압에 따라 사용하는 부품이 달라지게되는 종래에 비하여 유지 및 보수가 간편하게 되는 것이다.Thus, in the present invention, when the power is connected to the automatic voltage recognition circuit when operating the signal in the operation panel, the power is rectified through the rectifier is input to the converter is converted into the use voltage, the LED signal is operated through the LED drive When induction power (induction voltage, induction current) flows between the control panel and LED signal in the off state by cutting off the power of the signal from the control panel, the induction power lower than the set voltage is cut off from the converter, and the induction current lower than the set current As it is cut through the induction current blocking circuit of the LED drive, it effectively cuts off induction power (induction voltage, induction current) regardless of the distance between the operation panel and the signal, thereby eliminating the malfunction of the signal by the induction power. Use of automatic voltage recognition circuit that can automatically recognize voltage in the range of 265V and DC 120-374V It thereby becomes a simple maintenance and repair as compared to the conventional parts are used depending on the voltage to vary.

또 본 발명은 컨버터를 병렬로 구하게 되면 컨버터의 이상이 발생 될 경우 또다른 컨버터로 전압이 제어되어 안정적으로 전원을 공급할 수 있게 된다.In addition, when the converter is found in parallel, the present invention can stably supply power by controlling the voltage to another converter when an error occurs in the converter.

따라서 이상과 같은 본 발명은 철로에서 조작반과 신호기 사이에 발생되는 각종 유도전력은 LED신호기에 전달되지 못하게 효과적으로 차단됨으로써 신호기의 오작동을 해소할 수 있는 특징이 있다.Therefore, the present invention as described above has a feature that can eliminate the malfunction of the signal by effectively blocking the various induced power generated between the operation panel and the signal in the rail to be delivered to the LED signal.
