Based on a set of optic fiber sensors,an algorithm was proposed to count ships in inland waterways by combining the threshold of sound energy and the time-frequency characteristics of strong line spectrums,which solved the counting problem emerged when a number of ships went through the monitored water area in parallel.The processing results of a piece of 45 minutes long sound pressure data proved the effectiveness of this algorithm.
