Description

RFID를 이용한 철도차량용 정차역 무정차통과 방지 시스템{Non-stop pass prevention system for railway vehicles using RFID}Non-stop pass prevention system for railway vehicles using RFID}

본 발명은 무정차통과 방지에 관한 것으로, 더욱 상세하게는 안전상의 이유를 제외하고 열차가 정차하여야 하는 역에 대하여 서로 다른 거리에 미리 설치한 복수의 무선주파수 식별장치를 이용하여 경고음과 음성안내, 서행 및 정차를 하도록 하여 안전한 무정차통과 방지가 가능한 RFID를 이용한 철도차량용 정차역 무정차통과 방지 시스템에 관한 것이다.The present invention relates to the prevention of non-stop passing, and more particularly, by using a plurality of radio frequency identification devices pre-installed at different distances with respect to the station where the train should stop, except for safety reasons And it relates to a stop station non-stop pass prevention system for railway vehicles using RFID capable of preventing safe non-stop passing by making a stop.

일반적으로 전동차는 대도시의 복잡한 교통 문제, 협소한 도로문제, 과도한 보상문제 등의 해결을 위해 지하 또는 지상에 건설하여 저렴한 요금으로 교통의 막힘 없이 정한 목적지까지 안전하고 빠르게 갈 수 있는 대중 교통 수단으로 일반 대중이 가장 많이 이용하고 있다.In general, trains are constructed underground or on the ground to solve complex traffic problems, narrow road problems, and excessive compensation problems in large cities, and are a public transportation means that allows you to safely and quickly reach a designated destination at a low fare without traffic jamming. The public is using it the most.

기존의 열차 운행정보는 종합관제소의 열차운행 제어시스템에서 수집하여 안내정보를 각 역사의 정보통신실 제어기로 전송하며, 전송된 정보는 승강장에 설치된 LCD 디스플레이나 안내방송을 통하여 운행정보를 표출하며, 승강장 내의 대기 승객에게 운행정보를 인지시켜 탑승 등의 행위를 안내할 수 있도록 한다.Existing train operation information is collected by the train operation control system of the general control station and the guide information is transmitted to the information communication room controller of each station, and the transmitted information is displayed through the LCD display or announcement broadcast installed at the platform. By recognizing the operation information to the waiting passengers in the platform, it is possible to guide the boarding activities.

이러한 열차운행제어방식으로는 최근 ATC, ATS 등이 이용되고 있다.As such a train operation control method, ATC, ATS, etc. are recently used.

여기서 ATS(Automatic Train Stop device : 열차 자동 정지 장치)(이하, 간단히 'ATS'라 함)는 지상에서 많이 쓰이는 장치로서, 기관사가 수동으로 열차(지하철)(이하, 간단히 '열차'라 함) 운전을 하는 상태에서, 기관사가 일정시간 안에 열차를 정차시키지 않으면 강제적으로 열차를 정지시키는 장치이다.Here, ATS (Automatic Train Stop device) (hereinafter, simply referred to as'ATS') is a device that is widely used on the ground, and an engineer manually drives a train (subway) (hereinafter, simply referred to as a'train'). It is a device that forcibly stops the train if the engineer does not stop the train within a certain period of time.

ATC(Automatic Train Control device : 열차 자동 제어 장치)(이하, 간단히 'ATC'라 함)는 지하에서 많이 쓰이는 장치로서, 열차가 제한속도를 넘게 되면 자동으로 제한속도 아래로 제어하여 주는 장치이다.ATC (Automatic Train Control device) (hereinafter simply referred to as'ATC') is a device that is widely used underground and automatically controls the train below the speed limit when it exceeds the speed limit.

ATS는 열차를 자동으로 정지시키기는 하지만 기본적으로는 수동운행방식인데, 기관사가 수동으로 열차를 출발시키고, 수동으로 열차를 가속시키며, 수동으로 열차를 정차시키는 방식으로서, 특별한 상황, 예를 들어, 기관사가 일정시간 안에 열차를 정차시키지 않는 경우에는 ATS가 동작하여 열차를 강제적으로 정차시키는 방식이다.ATS stops trains automatically, but basically, it is a manual operation method.It is a method of manually starting the train by an engineer, manually accelerating the train, and manually stopping the train.Special circumstances, for example, If the engineer does not stop the train within a certain period of time, the ATS is activated and the train is forcibly stopped.

이하 첨부된 도면을 참조하여 종래 기술에 따른 수동운행방식에서의 무정차 역통과 방지를 위한 장치를 설명하기로 한다.Hereinafter, an apparatus for preventing non-stop reverse passage in a manual driving method according to the prior art will be described with reference to the accompanying drawings.

도 1은 종래 기술에 따른 수동운행방식에서의 무정차 역통과 방지장치를 나타낸 구성도이다.1 is a block diagram showing a non-stop reverse pass prevention device in a manual driving method according to the prior art.

종래 기술에 따른 무정차 역통과 방지장치는 도 1에 나타낸 바와 같이, 통과장애 예방대책으로 TCMS(Train Control and Monitoring System)를 구축하여 역 통과경보장치를 운영중에 있다.As shown in Fig. 1, the conventional non-stop reverse pass prevention device is operating a reverse pass warning device by constructing a Train Control and Monitoring System (TCMS) as a measure for preventing passage failure.

여기서 TCMS는 열차 종합 관리장치로서 TGIS의 발달형으로, 최신의 반도체 기술, 소프트웨어 기술과 데이터 커뮤니케이션 기술을 이용한 중앙 집중식 차내 정보제어(Centralized control of on-board information)를 위한 마이크로 컴퓨터 시스템이다. TCMS는 직렬 전송선을 차량에 있는 터미널과 연결시켜 차내 장치들을 집중적으로 제어 및 모니터링하는 열차 정보 관리 시스템의 역할을 한다. Here, TCMS is a developed type of TGIS as a comprehensive train management device, and is a microcomputer system for centralized control of on-board information using the latest semiconductor technology, software technology and data communication technology. TCMS acts as a train information management system that intensively controls and monitors in-vehicle devices by connecting serial transmission lines with terminals on the vehicle.

이러한 TCMS에서는 차륜직경, 정차역 정보, 역간 거리정보, 속도신호, 출입문 개발신호를 입력부에 입력하면 입력된 역간거리와 운행거리를 비교하여 전방 300m에서 1차경보(경고등 점멸), 전방 200m 지점에서 2차 경보(음성)를 하게 되고, 기관사는 정차를 위한 제동장치를 동작시키게 된다.In such TCMS, when the wheel diameter, stop station information, station distance information, speed signal, and door development signal are input to the input unit, the inputted station distance and the driving distance are compared, and the first warning (warning light flashes) at 300 m ahead, 2 at 200 m ahead. A car alarm (voice) is issued, and the engineer operates the brake system for stopping.

그러나 이러한 첨단장치의 구성에도 불구하고, 속도발전기의 오차나, 차륜직경, 차륜활주 등에 의한 주행거리 연산에 오차가 발생하는 문제가 있었고, 경보장치에 문제가 발생하거나, 인적오류에 따라 경보를 무시하는 등에 의해 무정차 통과 사례가 발생하는 문제가 있었다.However, despite the configuration of such a high-tech device, there was a problem that an error occurred in the calculation of the mileage due to an error in the speed generator, wheel diameter, and wheel sliding, and a problem occurred in the alarm device or the alarm was ignored due to human error. There was a problem in that a case of non-stop passing occurs due to such problems.
