Abstract
Description
본 발명은 열차 접근 경보 시스템으로 상세히는 기관차 및 기타 동력차(모터카, 검측차, 선로보수용 장비등)에 무선 전파발신장치를 고정 설치하여 열차의 정보를 선로상에서 작업을 하는 작업원의 단말기에 제공하는 시스템이다.The present invention is a train approach alarm system in detail installed in the locomotive and other power vehicles (motor cars, detection cars, track repair equipment, etc.) to provide a radio wave transmitting device fixed to provide the information of the train to the terminal of the worker working on the track It is a system.
통상 열차 운행선에서 작업시 작업위치에서 열차의 운행 속도에 따라 200~400미터 전방에 작업표지를 세워 열차 기관사에게 작업중임을 알려 열차 접근시 기적을 울려주는 경보체제를 사용하고 있다. 그러나 이 경보체제는 작업하는 보선원 및 보안원등이 보수장비의 소음, 부근을 통과하는 자동차, 항공기등의 소음, 작업에 대한 정신집중, 잡념등으로 열차의 기적을 인지하지 못하여 많은 안전사고가 발생하고 있다.In general, when working on the train line, the work mark is set 200 ~ 400 meters ahead according to the operating speed of the train at the working position to inform the train engineers that they are working, and an alarm system is used to sound a miracle when approaching the train. However, this alarm system has many safety accidents because the working ships and security officers are not aware of the miracle of the train due to the noise of maintenance equipment, the noise of cars, aircrafts, etc. passing through the vicinity, the concentration of work, and the thoughts. It is happening.
본 발명의 과제는 열차 운행선에서 작업하는 보선원 및 보안원에게 접근 열차의 정보를 보다 확실하게 제공함으로써 안전사고를 미연에 방지 하고자 하는 것이다.An object of the present invention is to prevent the safety accident in advance by providing the information of the approach train to the crew and security personnel working on the train service line more reliably.

본 발명의 구성을 첨부된 도면에 따라 상세히 설명하면 다음과 같다.Hereinafter, the configuration of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 발신장치와 수신장치의 관계를 설명한 개요도로써 경보 시스템의 작동 거리는 500m 내외로 설정하고 그 반경내에서 수신 감도를 측정하여 열차 상황을 알린다.1 is a schematic diagram illustrating the relationship between a transmitter and a receiver. The operating distance of the alarm system is set to about 500 m and the reception sensitivity is measured within the radius to inform the train situation.
발신 장치와 수신 장치는 각 상황들을 고유한 코드로서 구분하여 그 상황을 통보한다. 발신 장치에서 보낸 신호가 맞는지의 확인은 ID 코드를 수신하여, 수신 장치의 ID 코드와 비교함으로써 확인된다.The originating device and the receiving device identify each situation as a unique code and notify the situation. Confirmation that the signal sent from the originating device is correct is verified by receiving an ID code and comparing it with the ID code of the receiving device.
발신장치는 현재의 상황을 코드로 전달하며, 수신장치는 수신된 코드와 현재의 수신감도를 측정하여 상태별 경보 레벨 값을 통보한다.The originating device transmits the current situation to the code, and the receiving device measures the received code and the current reception sensitivity to notify the alarm level value for each state.
상태별 경보 레벨값은 아래와 같이 세 단계로 구분한다.Status level alarm level is divided into three stages as follows.
레벨 0 - 안전상황(열차 부재중 - 신호 수신이 안될 경우)Level 0-Safety situation (train missing-no signal received)
레벨 1 - 주의상황(저속운행중 30km/h미만, 거리 500m이상 혹은 역내이동중)Level 1-Attention (less than 30km / h during low speed, distance over 500m or moving in the station)
레벨 2 - 경보상황(고속운행중 30km/h이상, 거리 500m이내)Level 2-Alarm condition (over 30km / h during high speed, within 500m distance)
도 2는 지형지물등이 전파의 진행을 방해하는 경우로써 지형지물등이 전파의 진행을 방해 할 때에는 그 지점에 이동 중계기를 설치한다. 중계기는 전파의 수신 및 발신 두가지 기능을 동시에 갖는다.2 is a case where a feature or the like hinders the propagation of radio waves, and when a feature or the like hinders the propagation of radio waves, a mobile repeater is installed at the point. The repeater has both functions of receiving and sending radio waves at the same time.
도 3,4는 발신, 수신 장치의 구성도이다.3 and 4 are block diagrams of the transmitting and receiving apparatus.
도 5는 송신 데이터의 형식으로 각 상황을 알리기 위해서는 고유의 식별 코드가 요구된다. 고유식별 코드는 총 32비트로 구성되며, 통신에러가 발생할 경우를 고려하여 에러정정코드(CRC)를 사용한다. 고유 식별 코드는 8비트의 헤더와 8비트의 데이터코드, 16비트의 에러정정코드로 구성된다5, a unique identification code is required to inform each situation in the form of transmission data. The unique identification code consists of 32 bits in total and uses an error correction code (CRC) in consideration of a communication error. The unique identification code consists of an 8-bit header, 8-bit data code, and 16-bit error correction code.
도 6은 데이터의 송수신 코드 신호의 파형이며6 is a waveform of a transmission / reception code signal of data;
도 7은 본 경보시스템의 동작 Flowchart 로서 송신 장치에 전원이 공급되면, 송신장치는 대기 상태에서 동작 모드로 들어가고, 열차의 이동이나 속도 등을 읽어 열차의 상황을 송신한다. 안테나는 전방 지향성 안테나를 사용한다. 수신 단말기의 경우는 전원이 공급되면, 대기 상태에서 무선 전파를 수신하여 코드 정보가 들어오는지를 체크한다. 만약 코드 정보가 들어오면 코드 정보를 수신하여 전송 오류 체크를 한다. 데이터에 오류가 없을 경우 헤더를 확인하여 그 정보가 맞으면, 데이타를 해독하여 현재 상황을 벨이나 진동으로 알린다. 수신 단말기의 안테나는 무지향성 PCB Pattern 안테나를 사용한다.7 is an operation flowchart of the alarm system. When power is supplied to the transmission apparatus, the transmission apparatus enters the operation mode in the standby state, and reads the movement or speed of the train to transmit the train status. The antenna uses a forward directional antenna. In the case of the receiving terminal, when power is supplied, it receives a radio wave in a standby state and checks whether code information is received. If the code information is received, the code information is received and the transmission error is checked. If there is no error in the data, check the header and if the information is correct, the data is decrypted and the current situation is announced by bell or vibration. The antenna of the receiver terminal uses an omni-directional PCB pattern antenna.
이상에서와 같이 본 발명에 의하면 열차 운행선에서 작업하는 보선원 및 보안원등이 여러 가지 사유로 열차의 기적을 인지하지 못하여 발생하는 안전사고를 대폭 줄일 수 있으며 건널목에도 본 발명을 접목하면 많은 인적, 물적 피해를 줄일 수 있다.As described above, according to the present invention, the safety incidents caused by the crew and the security guard working on the train service line can be greatly reduced due to various reasons, and the present invention can be applied to the railroad crossings. Therefore, physical damage can be reduced.
