본 발명은 철도차량의 DMC(Dead-Man Control)시스템에 관한 것으로, 특히 철도차량의 운행시 운전사가 졸거나 부주의하여 안전운행에 지장이 발생하는 경우에 경보가 발생함과 더불어 긴급제동이 수행되는 철도차량의 DMC시스템에 관한 것이다.The present invention relates to a dead-man control (DMC) system of a railway vehicle, and in particular, an emergency braking is performed while an alarm is generated when a driver is asleep or inadvertently interferes with safety operation during operation of the railway vehicle. It relates to the DMC system of rolling stock.

일반적으로, 철도차량은 일정한 철도레일상을 다수의 승객과 다량의 화물이 탑재된 상태로 장시간 동안 단조롭게 운행되기 때문에 운전사가 집중력이 저하되어 부주의하게 되거나 수면운전을 발생하는 등 철도차량의 안전운행을 유지할 수 없게 되는 바, 이를 방지하기 위해 종래에는 운전자가 수동으로 일정한 압력을 발생함으로써 단속되는 마스터제어핸들(MCH)과 소정의 지연시간을 가지고 철도의 제동장치를 작동시키도록 된 비상자기밸브(EMV)로 구성되어 있다.In general, railway cars operate monotonously for a long time with a large number of passengers and a large amount of cargo mounted on a certain railroad, so the driver may be inadvertently concentrated, causing inadvertent driving or surface driving. In order to prevent this, in order to prevent this, conventionally, the driver generates a certain pressure manually, and an emergency magnetic valve (EMV) which operates the brake system of the railway with a predetermined delay time and the master control handle (MCH) that is interrupted. It consists of).

한편, 운전자가 철도차량을 정상운행시키기 위해서는 상기 마스터제어핸들(MCH)을 일정한 압력으로 계속 누르고 있어야 하고, 만약 운전자가 졸거나 부주의 하여 상기 마스터제어핸들(MCH)에 제대로 압력을 가하지 않게 되는 경우 상기 비상자기밸브(EMV)가 동작하게 되어 철도차량의 비상제동장치가 동작하게 된 것이다.On the other hand, the driver must keep pressing the master control handle (MCH) at a constant pressure in order to operate the railway vehicle normally, and if the driver doze or carelessly press the master control handle (MCH) properly The emergency magnetic valve (EMV) is operated to operate the emergency braking system of the railway vehicle.

그러나, 종래의 철도차량의 DMC시스템은 철도차량이 장시간에 걸쳐 운행되는 교통수단임을 감안할 때 열차의 운행중 계속하여 마스터제어핸들(MCH)을 손으로 계속 누르고 있게 하는 것은 운전자에게 피로를 야기함과 더불어 운전자가 정상적인 운행을 할 수 있는 상태인지의 여부를 단순히 마스터제어핸들(MCH)에 눌려져 있는 상태에서만 판단하게 되고, 또한 일정한 압력을 유지하여 줄 수 있는 간단한 기구를 운전자가 임의로 설정하면 경보용 보조장치가 무력하게 되는 문제점이 있었다.However, considering that the DMC system of a conventional railway vehicle is a means of transportation that is operated for a long time, keeping the master control handle (MCH) pressed by hand continuously during operation of the train causes fatigue to the driver. The driver can judge whether the driver can operate normally only by pressing the master control handle (MCH), and also if the driver arbitrarily sets a simple mechanism that can maintain a constant pressure, the alarm assist device There was a problem of becoming powerless.

이에 본 발명은 상기한 문제점을 해결하기 위한 것으로, 철도차량의 운행시 운전사가 졸거나 부주의하여 안전운행에 지장이 발생하는 경우에 경보가 발생함과 더불어 긴급제동이 수행되는 철도차량의 DMC시스템을 제공하는데 그 목적이 있다.Accordingly, the present invention is to solve the above problems, when the operation of the railway vehicle is a sleepy or inadvertent obstacles to the safe operation when the alarm occurs and emergency braking DMC system of the railway vehicle is performed The purpose is to provide.
