Abstract

본 발명은 철도차량에서 전류루프신호를 RS232C신호를 이용하여 시험할 수 있는 철도차량용 모니터 시스템의 직렬통신 시험장치에 관한 것으로, 차량용 제어장치들에서 발생된 정보를 수집하고 처리하기 위하여 차량용 제어장치들과 전류루프에 의한 직렬통신방식에 의해 통신하는 모니터 시스템; 상기 모니터 시스템을 시험하기 위하여 디지탈전압레벨로 데이타를 송수신하는 컴퓨터; 상기 컴퓨터의 디지탈전압 레벨신호를 상기 모니터시스템의 전류루프에 의한 직렬통신방법에 적합한 전류레벨신호로 변환하기 위하여 제1변환수단; 및 상기 모니터 시스템의 전류루프에 의한 직렬통신방식에 의한 전류레벨 신호를 상기 컴퓨터의 디지탈전압 레벨신호로 변환하기 위한 제2변환수단을 구비한다. 본 발명에 의하면, 모니터링 장치내의 직류루프회로의 전류신호를 컴퓨터와 통신할 수 있는 신호레벨로 변환함으로써, 차량기기 대신에 컴퓨터를 이용하여 모니터링 장치에 대한 통신 프로토콜을 시험할 수 있다.The present invention relates to a serial communication test apparatus for a railway vehicle monitor system capable of testing a current loop signal using a RS232C signal in a railway vehicle, and includes vehicle control apparatuses for collecting and processing information generated from vehicle control apparatuses. A monitor system for communicating by serial communication with an overcurrent loop; A computer for transmitting and receiving data at a digital voltage level to test the monitor system; First conversion means for converting the digital voltage level signal of the computer into a current level signal suitable for a serial communication method by a current loop of the monitor system; And second converting means for converting the current level signal by the serial communication method by the current loop of the monitor system into the digital voltage level signal of the computer. According to the present invention, by converting the current signal of the DC loop circuit in the monitoring device into a signal level that can communicate with a computer, the communication protocol for the monitoring device can be tested using a computer instead of the vehicle equipment.
