Abstract

In the case of the existing train control system, the driver monitors the condition of the vehicle through a composite controller device that displays various information on a screen in the vehicle. However, when problems arise such as car trouble, it is difficult for the drivers to take action immediately. In addition, maintenance personnel have to manually save data one by one after storing the vehicle to analyze control information of the main devices such as the brake controller and auxiliary power. To improve these points, a system that sends and receives all information in real time should be established by installing a sensor communication network and a surveillance system. This study attempts to improve the safety and maintenance of rail vehicles by suggesting a standardized method for train control and surveillance system.

기존 전동차 제어시스템의 경우에는 종합제어장치를 통하여 차량 내의 각종 정보를 운전자 화면에 현시하여 운전자가 차량의 상태를 감시하도록 구성되어 있다. 그러나 차량고장 등과 같이 갑작스런 사고가 발생할 경우에는 운전자가 당황하여 정확한 고장조치를 하기 어려운 것이 현실이다. 또한 제동제어기 및 보조전원장치 등 주요장치들의 제어정보를 분석하기 위하여 차량이 기지에 입고되고 난 후에 유지보수원이 현장에서 일일이 수동으로 데이터를 저장하는 매우 비효율적인 유지보수시스템으로 운영되고 있다. 이러한 점을 개선하기 위해서는 차량 내에 센서통신네트워크 및 감시시스템을 설치하여 차량 내의 모든 정보를 실시간으로 송수신하는 시스템을 구축하여야 한다. 본 연구에서는 이러한 시스템 구축을 위하여 전동차 제어 및 감시시스템의 표준화 방안을 제시함으로써, 이를 통해 차량시스템의 안전성을 향상하고 유지보수를 보다 효율적으로 개선하고자 한다.
