Description

철도차량 제동상태의 측정장치 및 방법{DEVICE AND METHOD THEREOF FOR MEASURING BRAKING-CONDITION IN RAILROAD CARRIAGES }DEVICE AND METHOD THEREOF FOR MEASURING BRAKING-CONDITION IN RAILROAD CARRIAGES}

본 발명은 철도차량의 제동장치에 관한 것으로서, 특히 운행중인 차량이 제동이 체결된 후, 제동시작점부터 제동종료까지의 제동상태를 압력센서로서 감지하고, 상기 감지한 정보를 실시간으로 메모리카드에 저장시킴과 더불어 상기 저장된 정보를 이용하여 철도차량의 제동상태를 출력하여 현시적으로 판별할 수 있도록 된철도차량의 제동상태 측정장치와 방법을 제공함을 특징으로 한다.The present invention relates to a braking device for a railway vehicle, and in particular, after a running vehicle is braked, a braking state from a braking start point to a braking end is detected as a pressure sensor, and the detected information is stored in a memory card in real time. In addition, the present invention provides an apparatus and method for measuring a braking state of a railway vehicle, which can be used to output a braking state of a railway vehicle using the stored information.

일반적으로, 철도 차량을 제동하기 위한 제동 시스템은 압축공기를 이용한 공기압제동장치가 적용되고 있는바, 이와 같이 공기압에 의한 종래 제동 시스템은 기관차로 구성된 제동밸브의 작동에 따라 각 차량간에 연결된 제동관을 통하여 후부차량에 압력신호를 전달하는 구조를 갖는 것으로서,In general, a braking system for braking a railway vehicle is applied with a pneumatic brake system using compressed air. Thus, a conventional braking system based on pneumatic pressure uses a braking tube connected to each vehicle according to the operation of a braking valve composed of a locomotive. As having a structure for transmitting a pressure signal to the rear vehicle through,

이는 도 1에 도시된 바와 같이 기관차에 탑재된 공기압축기와 각 차량으로 부착되는 보조공기통(1)을 제동관(5)에 의해 연결시켜 제동관(5)과 보조공기통(1)에 일정한 공기압을 충기토록 하되, 상기 제동관(5)과 보조공기통(1)의 사이로는 일방향밸브를 설치하여 제동관(5)으로부터 보조공기통(1)으로만 공기가 유입되도록 구성되고,As shown in FIG. 1, the air compressor mounted on the locomotive and the auxiliary air cylinder 1 attached to each vehicle are connected by the brake tube 5 to provide a constant air pressure to the brake tube 5 and the auxiliary air cylinder 1. It is to be filled, but between the braking tube 5 and the auxiliary air cylinder (1) by installing a one-way valve is configured so that air flows only from the braking tube (5) to the auxiliary air cylinder (1),

각 차량의 보조공기통(1)으로는 상기 제동관(5)의 압력변화에 따라 삼동작용을 하는 제어밸브와 제륜자(3a)의 링크기구와 연결되어 제륜자(3a)를 차륜(W)에 밀착시키는 제동실린더(3)가 연결되는 구조를 갖는 것이다.As the auxiliary air cylinder 1 of each vehicle, it is connected to the control valve and the link mechanism of the wheel setter 3a, which acts according to the pressure change of the braking tube 5, to connect the wheel setter 3a to the wheel W. It has a structure in which the braking cylinder 3 to be in close contact is connected.

이에, 상기와 같은 구조의 철도차량용 제동장치에 의해 행하여지던 종래 제동 시스템에 의한 열차의 제동 시에는 기관차가 기관차내의 제동밸브를 작동, 제동관(5)의 압력을 하강시키게 되면, 제동관(5)의 압력변화신호를 전달받는 제어밸브는 보조공기통(1)의 압축공기를 제동실린더(3)로 이동케 하여 제동실린더(3)와 연결된 링크기구를 작동시켜 제륜자(3a)를 차륜(W)에 밀착시키므로 제동력을 얻게 되는 것이며,Therefore, when braking the train by the conventional braking system performed by the railway vehicle braking system having the above structure, when the locomotive operates the brake valve in the locomotive and lowers the pressure of the braking tube 5, the braking tube 5 The control valve which receives the pressure change signal of) moves the compressed air of the auxiliary air cylinder (1) to the brake cylinder (3) to operate the link mechanism connected to the brake cylinder (3) to drive the wheelset (3a) to the wheel (W). ) So you get a braking force,

제동력의 완화 시는 제동밸브를 제어 주공기통(4)의 압축공기를 제동관(5)과보조공기통(5)으로 보내 압력을 상승시키게 되며 제동관(5)의 압력상승신호를 받은 제어밸브의 작동으로 제동실린더(3)에서 작용하던 공기를 대기로 방출시키게 되고, 링크기구에 연결된 스프링의 탄성회복력에 의해 차륜(W)에 밀착되었던 제륜자(3a)를 원위치되도록 함으로써 제동력이 완화되는 것이다.When the braking force is relieved, the pressure is increased by sending the compressed air of the control main cylinder (4) to the brake tube (5) and the auxiliary air cylinder (5), and the control valve receiving the pressure rise signal of the brake tube (5). By releasing the air acting on the braking cylinder (3) by the operation, the braking force is alleviated by bringing the wheel (3a) in close contact with the wheel (W) by the elastic recovery force of the spring connected to the link mechanism.

상기와 같은 철도차량의 제동 구조와 동작에서는 차량이 정지된 상태에서 제동장치를 정확히 점검하기가 어렵다. 일반적으로, 차량기지에서 기관차와 객차를 연결하여 출발직전 보수요원이 육안으로만 개별차량의 제동기 동작상태를 파악하게 된다. 따라서, 철도차량의 제동장치를 많은 인력이 투입되어 점검함이 불가피하고, 출발전 점검시간이 과도하게 소요됨은 물론 정확한 동작상태를 파악하기 어렵다.In the braking structure and operation of the railway vehicle as described above, it is difficult to accurately check the braking device in a stopped state of the vehicle. In general, by connecting the locomotive and the passenger car at the vehicle base, the maintenance personnel immediately grasp the brake state of the individual vehicle only with the naked eye. Therefore, it is unavoidable to check the braking system of the railway vehicle by inputting a large number of personnel, and it is difficult to determine the exact operating state as well as excessively checking time before departure.

또한, 개별 객차간의 제동시간 지연에 따른 객차와 객차간의 충돌이 발생한 경우에는 승객에게 불안감을 조성할 뿐 아니라 노약자 및 임산부가 탑승한 경우에는 보다 심각한 상황이 발생할 수 있다.In addition, when a collision between a carriage and a carriage occurs due to a delay in braking time between individual carriages, not only may anxiety be caused to passengers, but also more serious situations may occur when the elderly and pregnant women are on board.

이에 본 발명은 상기와 같은 제반 문제점을 해결하기 위해 발명된 것으로,Thus, the present invention was invented to solve the above problems,

차량 정지상태에서의 제동상황 뿐만 아니라 운행 중 제동상태를 모두 기록 관리하여 제어상태의 문제점을 사전에 해결할 수 있는 철도차량의 제동상태 측정장치 및 방법을 제공한다The present invention provides an apparatus and method for measuring a braking state of a railway vehicle, which records and manages not only a braking situation in a vehicle stop state but also a braking state during operation to solve a problem of a control state in advance.
