The present invention relates to a system for monitoring the travelling state of a train by considering the communication state of the train. The system comprises: a data preprocessing unit which extracts data from sensing data detected by a low power sensor formed in a train, and generates a packet by including the extracted data; a packet transmitting unit which transmits the packet to a train monitoring platform through a mobile communication network; and a link state detecting unit which determines whether a wireless link with the train monitoring platform is disconnected. As recovering to a normal state after the wireless link disconnection from the determination result of the link state detecting unit, the data preprocessing unit generates the packet by including an average and a variance value of the data extracted from the sensing data during time between the wireless link disconnection and the recovery thereof. Therefore, the system for monitoring the travelling state of a train can reliably monitor the state of the train.

    본 발명은 열차의 통신 상태를 고려한 열차 주행 상태 모니터링 시스템에 관한 것으로, 열차에 형성된 저전력 센서에서 감지된 센싱 데이터로부터 데이터를 추출하고, 추출된 데이터를 포함하여 패킷을 생성하는 데이터 전처리부; 상기 패킷을 이동통신망을 통해 열차 모니터링 플랫폼으로 전송하는 패킷 송신부; 상기 열차 모니터링 플랫폼과의 무선링크 두절여부를 판단하는 링크 상태 검출부;를 포함하고, 상기 링크 상태 검출부의 판단결과 무선링크 두절 이후 정상으로 복구됨에 따라, 상기 데이터 전처리부는 무선링크 두절 이후 복구 사이의 시간 동안 상기 센싱 데이터로부터 추출된 데이터의 평균값과 분산값을 포함시켜 패킷을 생성한다. 이로 인해, 열차의 상태를 신뢰성 있게 모니터링할 수 있는 효과가 있다.
