Abstract

An auxiliary power supply system of an indoor guide display for a railcar is provided to operate the next guide display even though the first guide display is not operated by the cutting-off of a main power by operating an auxiliary power. An auxiliary power supply system of an indoor guide display for a railcar includes a main power(110), a main power switch(120), a main power detecting circuit(130), a main power input circuit(140), an auxiliary power operating circuit(170), an auxiliary power(160), and an auxiliary power input circuit(180). The main power(110) supplies a power to the indoor guide display. The main power detecting circuit(130) determines whether the main power(110) is normally operated. The main power switch(120) maintains a closed state when the main power(110) is normally operated, and is opened when the main power(110) is abnormally operated. The main power input circuit(140) converts the main power(110) passed through the main power detecting circuit(130) into a power suitable for the indoor guide display when the main power switch(120) maintains the closed state. The auxiliary power operating circuit(170) maintains an inactive state when the main power(110) is normally operated, and is operated when the main power(110) is abnormally operated. The auxiliary power(160) is operated by the operation of the auxiliary power operating circuit(170). The auxiliary power input circuit(180) converts the auxiliary power(160) into the power suitable for the indoor guide display when the auxiliary power(160) is operated.

본 발명은, 전동차 실내 안내표시기의 보조전원 시스템으로서, 특히 실내 안내표시기에 공급되는 주전원이 차단되는 경우에 보조전원을 동작시켜 첫번째 전동 차 실내 안내표시기가 동작하지 않더라도, 그 이후의 전동차 안내표시기를 동작시킬 수 있는 전동차 실내 안내표시기 보조전원 시스템에 관한 것이다.The present invention relates to an auxiliary power system of an indoor guide of an electric vehicle, in particular, when the main electric power supplied to the indoor guide is cut off and the auxiliary electric power is operated so that the first electric vehicle indoor indicator is not operated. The present invention relates to an electric vehicle indoor guide indicator auxiliary power system that can be operated.

현재, 전동차 실내 안내표시기로서 많이 이용되고 있는 LCD 실내 안내표시기에 고화질의 영상 데이터를 전송하기 위해서는 대략 1GHz 이상의 전송속도를 필요로 하며, 이러한 전송에 있어서의 전송 매체로는 광케이블, 동축 케이블, 무선 등이 있을 수 있다. 그러나, 각 매체마다 전송 속도에 따른 전송 거리가 있으므로, 일정거리마다 중계기를 설치하여야 한다.In order to transmit high-quality image data to LCD indoor guides, which are widely used as indoor guides for electric vehicles, transmission speeds of about 1 GHz or more are required, and transmission media in such transmissions include optical cables, coaxial cables, and wireless devices. This can be. However, since each medium has a transmission distance according to the transmission rate, a repeater must be installed at a predetermined distance.

한편, 이러한 중계기는 전원에 문제가 발생하면 신호 전달이 불가능하므로 전동차와 같은 곳에서는 반드시 전원의 이상동작에 대한 문제를 고려하여야 한다.On the other hand, such a repeater can not transmit a signal if a problem occurs in the power supply, so in the place such as an electric vehicle must consider the problem of abnormal operation of the power supply.

이하, 첨부된 도면을 참조하여 종래 기술의 문제점을 설명한다.Hereinafter, the problems of the prior art will be described with reference to the accompanying drawings.

도 1 은 종래의 전동차 실내 안내표시기의 주전원 시스템을 나타내는 구성도이다.1 is a block diagram showing a main power system of a conventional indoor vehicle guide display.

The main power supply which has passed through the detection circuit 30 is converted into a main power input signal 150 which is a signal suitable for an electric vehicle indoor device such as an LCD electric vehicle indoor guide and outputs. In this case, since the sub power supply operation circuit 170 does not operate, the supply of the sub power supply 160 is not performed.

한편, 주전원 (110) 이 외부의 요인 또는 자체고장에 의해 정상적으로 동작하지 않는다면 주전원 검출회로 (130) 는 주전원 (110) 이 비정상적으로 동작하고 있음을 감지하여 주전원 개폐기 (120) 를 개방시킴과 동시에, 보조전원 동작회로 (170) 를 동작시키고, 이에 따라 보조전원 (160) 이 다이오드 (170) 를 거쳐 보조전원 입력회로 (180) 에 공급된다. 보조전원 입력회로 (180) 는 입력된 보조전원 신호를 LCD 전동차 실내 안내표시기와 같은 전동차 실내장치에 적합한 신호로 변환하여 출력한다. 여기에서, 보조전원 (160) 은 그 일 실시예로서 운전실에 설치된 중앙제어장치내에서 출력되며, 바람직하게는 DC 24V 의 값을 갖는다.On the other hand, if the main power source 110 does not operate normally due to external factors or self-failure, the main power detection circuit 130 detects that the main power source 110 is abnormally operated and simultaneously opens the main power switch 120. The auxiliary power source operation circuit 170 is operated, and thus the auxiliary power source 160 is supplied to the auxiliary power source input circuit 180 via the diode 170. The auxiliary power input circuit 180 converts the input auxiliary power signal into a signal suitable for an indoor vehicle indoor apparatus such as an LCD electric vehicle indoor guide and outputs the converted auxiliary power signal. Here, the auxiliary power supply 160 is output in a central control unit installed in the cab as one embodiment, and preferably has a value of DC 24V.

이상, 설명한 바와 같이 전동차 실내 안내표시기의 보조전원 시스템을 구성하면, 실내 안내 표시기에 공급되는 주전원이 차단되더라도 보조전원을 동작시켜 그 이후의 전동차 안내표시기를 동작시킬 수 있다.As described above, when the auxiliary power system of the indoor guide indicator of the electric vehicle is configured, even if the main power supplied to the indoor guide indicator is cut off, the auxiliary power may be operated to operate the electric vehicle guide indicator thereafter.

이상에서는 본 발명을 특정의 바람직한 실시예를 참조하여 설명하였으나, 본 발명은 상기한 실시예에 한정되지 아니하며 본 발명의 요지를 벗어나지 않는 범위 내에서 당해 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의하여 다양한 변경과 수정이 이루어질 수 있는 것이다.In the above, the present invention has been described with reference to specific preferred embodiments, but the present invention is not limited to the above-described embodiments and those skilled in the art without departing from the gist of the present invention. The various changes and modifications can be made by.

상기한 바와 같은 본 발명은, 실내 안내표시기에 공급되는 주전원이 차단되는 경우에 보조전원을 동작시켜 첫번째 전동차 실내 안내표시기가 동작하지 않더라 도, 그 이후의 전동차 안내표시기를 동작시킬 수 있는 효과가 있다.According to the present invention as described above, even when the main electric power supplied to the indoor guide is cut off, the auxiliary power is operated to operate the electric car guide indicator thereafter even if the first electric car indoor guide is not operated. .
