Description

열차의 출입문 닫힘 자동경보 시스템Door Closed Auto Alarm System

본 고안은 전동차의 출입문 개폐 시스템에 관한 것으로 특히, 출입문 제어회로 및 방송장치 사이에 계전기수단을 구비하여 출입문이 닫힐 때 자동으로 경고방송을 하는 시스템에 관한 것이다.The present invention relates to a door opening and closing system of an electric vehicle, and more particularly, to a system for automatically alerting when a door is closed by providing a relay means between a door control circuit and a broadcasting device.

종래의 전동차에서는, 기관사가 육성으로 출입문을 닫는다는 것을 방송한 후에, 출입문 개폐스위치를 조작하여 출입문을 닫았다.In a conventional electric car, after the engineer broadcasts that the door is closed by nurturing, the door is closed by operating the door open / close switch.

그러나 본 고안을 이용한 전동차에서는, 기관사가 출입문을 닫을 때 직접 육성으로 방송하지 않더라도, 기관사가 출입문 개폐스위치를 조작하면 자동으로 경고방송이 되도록 이루어졌다.However, in the electric vehicle using the present invention, even if the engineer does not directly broadcast when closing the door, the engineer was made to be automatically alerted when operating the door opening and closing switch.

상기한 목적을 달성하기 위해, 본 고안에서는 방송장치에 출입문의 닫힘신호를 방송장치로 전송하기 위한 계전기 접점(3, 4) 및 시한 계전기(5, 6)로 구성된 인터페이스를 제공한다.In order to achieve the above object, the present invention provides an interface consisting of relay contacts (3, 4) and time relay (5, 6) for transmitting the door closing signal to the broadcast device.

도 1은 본 고안에 따른 출입문 자동경보 시스템의 회로도이다.1 is a circuit diagram of an automatic door alarm system according to the present invention.

<도면의 주요부분에 대한 부호의 설명><Description of the symbols for the main parts of the drawings>

1 --- 출입문 개폐스위치, 2 --- 도어 계전기 코일,1 --- door open / close switch, 2 --- door relay coil,

3 --- 도어 계전기 b접점, 4 --- 도어 계전기 a접점,3 --- door relay b contact, 4 --- door relay a contact,

5 --- 시한 계전기 접점, 6 --- 시한 계전기 코일,5 --- time relay contact, 6 --- time relay coil,

7 --- 방송장치.7 --- Broadcasting device.

본 고안에 따른, 열차의 출입문 닫힘 자동경보 시스템은 출입문 개폐스위치(1), 도어 계전기 코일(2) 및 도어 계전기 a 및 b접점(4, 3)과 시한 계전기 접점(5) 및 시한 계전기 코일(6)로 구성된다.According to the present invention, the door closing automatic alarm system of a train includes a door opening and closing switch (1), a door relay coil (2) and a door relay a and b contacts (4, 3) and a time relay contact (5) and a time relay coil ( 6) consists of.

(실시예)(Example)

이하, 첨부된 예시도면을 참조하여 본 고안의 실시형태를 설명한다.Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

먼저, 출입문을 열때의 회로동작을 설명한다.First, the circuit operation when opening the door will be described.

기관사가 개폐 스위치(1)을 단락시키면 도어 계전기 코일(2)이 여자됨에 따라 도어 계전기 b접점(3)이 개방되고 도어 계전기 a접점(4)이 단락된다. 이때 도어 계전기 b접점(3)이 개방되므로 방송장치(7)로 신호가 전송되지 않는다.When the engine driver short-circuits the on / off switch 1, the door relay coil 2 is opened, and the door relay b contact 3 is opened and the door relay a contact 4 is shorted. At this time, since the door relay b contact 3 is opened, no signal is transmitted to the broadcasting device 7.

다음으로, 출입문을 닫을때의 동작은 다음과 같다.Next, the operation when closing the door is as follows.

기관사가 개폐 스위치(1)를 개방시키면, 도어 계전기 코일(2)이 소자됨에 따라 도어 계전기 b접점(3)이 단락되고 도어 계전기 a접점(4)이 개방된다. 이때, 여자되어 있던 시한 계전기 코일(6)이 소자되고, 시한 계전기 접점(5)은 일정한 시간이 지난후에 접점이 떨어지게 설정되어 있다. 여기에서, 단락된 도어 계전기 b접점(3)과 일정한 시간동안 단락되어 있는 시한 계전기 접점(5)을 매개로 DC 100V 전원이 방송장치로 입력되어 방송장치에서 방송을 출력한다.When the engine operator opens and closes the switch 1, the door relay coil 2 is shorted and the door relay b contact 3 is shorted and the door relay a contact 4 is opened. At this time, the time relay coil 6 which has been excited is set, and the time relay contact 5 is set so that a contact may fall after a fixed time. Here, the DC 100V power is input to the broadcasting apparatus via the shorted door relay b contact 3 and the time relay contact 5 shorted for a predetermined time, and the broadcasting apparatus outputs the broadcasting.

이때, 도시한 바와 같이, 시한 계전기 접점(5)은 도어 계전기 b접점(3)의 하단부에 설치되고 시한 계전기 코일(6)이 소자되어도 일정한 시간이 지난 후에 OFF되도록 설정되어, 출입문 개폐스위치(1)가 빠른 속도로 ON/OFF되어도 방송이 출력되지 않도록 동작한다.At this time, as shown in the figure, the time relay contact point 5 is installed at the lower end of the door relay b contact point 3 and is set to turn off after a certain time even when the time relay coil 6 is demagnetized, and the door opening / closing switch 1 Even if) is ON / OFF at high speed, it does not output broadcasting.

참고로, 출입문 개폐스위치(1) 및 도어 계전기 코일(2)은 열차의 출입문 제어회로(도시되지 않음)내에 포함되어 있으며, 상기 고안에 대한 실시예, 구성 및 도면은 열차의 한쪽면의 출입문에 대한 것으로서, 실제 사용에 있어서 본 고안은 2개가 한쌍으로 사용되어 열차의 양쪽 출입문에 대해 동작한다.For reference, the door open / close switch 1 and the door relay coil 2 are included in the door control circuit (not shown) of the train, and embodiments, configurations, and drawings for the above-described design are provided on the door of one side of the train. In practical use, the present invention uses two pairs to operate on both doors of a train.

출입문을 닫을 때마다 기관사가 육성으로 방송하는 번거로움을 피할 수 있을 뿐 아니라, 기관사가 출입문 닫힘방송을 하지 않아도 자동으로 출입문이 닫힐 때 경고방송이 출력됨으로 해서 승객의 안전을 도모할 수 있고 기관사는 운전에만 전념할 수 있다.Whenever the door is closed, the driver can avoid the hassle of fostering the broadcast, and even when the door is closed, the warning broadcast is automatically output when the door is closed. You can concentrate on driving.
