APPARATUS AND METHOD FOR DETECTING OF LINE OBSTRUCTION

摘要

PURPOSE: A railway fault position detection device and a method thereof are provided to decide the fault position of the communication line by using the transfer time of the signal. CONSTITUTION: A failure position detection part(105) detects the failure position of a line by using the difference of the transmission delay time of the second signal and the transmission delay time of the first signal, and distance between the second terminal and the first terminal. The second signal is received in the first terminal. The first signal is received in the second terminal. In case the intensity when the second signal is selected is not satisfied, or the intensity when the first signal is selected is not satisfied, the failure position detection part detects the failure position of the line again.
